Description

But a kind of slide plate of relative motion

Technical field

The utility model relates to a kind of amusement apparatus, more particularly, relates to a kind of propulsive mechanism of slide plate.

Background technology

Public slide plate and scooter principle of propeller are well-known, and sliding continuously by the operator of scooter constantly pedaled realization with pin backward.Because slide plate and scooter are in the process of advancing fast, the operator not only sprains legs and feet with pin continuously backward with pedaling easily, but also causes the irregular wear of shoes easily.In order to solve the problem that prior art exists, people have proposed some and have promoted the technical scheme of slide plate and scooter indirectly.Such as, " self walking type scooter with foldable frame " that China Patent No. CN200510099722.8 proposes.Though the technical scheme of this utility model has solved the slide mode of operator with the feet step on the ground, also avoided the irregular wear of shoes.But " two telescopic chute " in this technical scheme is easy to generate bigger resistance in the contractile motion process.

Summary of the invention

At the deficiencies in the prior art, but the purpose of this utility model provides a kind of slide plate of relative motion, and it can make operator's both feet stand in and advance slide plate on the slide plate.

But the purpose of this utility model is achieved in that a kind of slide plate of relative motion, and front slide and tail skid have pulley, and front slide constitutes scalable the connection with tail skid by sleeve pipe and slide bar; Between front slide and the tail skid back-moving spring is arranged; Tail skid has propulsive mechanism.

On the such scheme basis, the utility model also has following further step:

Described sleeve pipe and slide bar are for can relatively rotate structure.

Described propulsive mechanism is the pulley of band freewheel clutch on the tail skid.

Described propulsive mechanism is the brake block on the tail skid, and tail skid is the tiltable structure.

Described front slide connects pulley by steeraxle.

Described front slide is provided with steering handle, and front slide connects pulley by steering handle.

Each 1 of described sleeve pipe and slide bar.

Between described sleeve pipe and the slide bar ball is arranged.

Advantage of the present utility model is as follows:

Because front slide constitutes scalable the connection with tail skid by sleeve pipe and slide bar; Between front slide and the tail skid back-moving spring is arranged; Tail skid has propulsive mechanism.So the utility model has not only been simplified being connected between front slide and the tail skid, but also help simplifying the structure of propulsive mechanism.

Propulsive mechanism can be the brake block on the slide plate, or the freewheel clutch on the pulley.Brake block and the freewheel clutch on the pulley on the slide plate are used to advance slide plate, and operator's only using foot is back and forth pedaled tail skid and can be promoted slide plate continuously and travel forward.Comparatively speaking, use brake block more to help simplified structure on the slide plate.The utility model not only can both feet stands in and advances slide plate on the slide plate, and reliable operation.

The specific embodiment

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:

Referring to Fig. 1 and Fig. 2.But a kind of slide plate of relative motion, front slide 1 and tail skid 4 are equipped with pulley 5 respectively, and front slide 1 and tail skid 4 can carry human body weight, and pulley 5 can use the pulley on the existing slide plate.Front slide 1 can be connected pulley 5 by steeraxle 200 respectively with tail skid 4; Iff being that front slide 1 connects pulley 5 by steeraxle, promptly described front slide 1 connects pulley 5 by steeraxle 200.Steeraxle 200 can use prior art.Pulley 5 quantity on front slide 1 and the tail skid 4 can be decided as required, on front slide 1 and the tail skid 42 pulleys 5 can be installed respectively; Perhaps as shown in Figure 3,2 pulleys 5 are installed on the front slide 1,1 pulley 5 is installed on the tail skid 4.Fix 1 length on the front slide 1 and be 60 centimetres sleeve pipe 2,5 centimetres of the external diameters of sleeve pipe 2,4 centimetres of internal diameters; Fix 1 length on the tail skid 4 and be 60 centimetres slide bar 3, the diameter of slide bar 3 is 3.6 centimetres; Slidably, promptly front slide 1 constitutes scalable be connected by sleeve pipe 2 with slide bar 3 with tail skid 4 to sleeve pipe 2 kinks on slide bar 3.Sleeve pipe 2 can use pipe, and slide bar 3 uses round bar, and sleeve pipe 2 kinks are rotatable on slide bar 3, and promptly described sleeve pipe 2 and slide bar 3 are for can relatively rotate structure.Be noted that because sleeve pipe 2 and slide bar 3 play the guiding role, and sleeve pipe 2 can use steel tubes slide bar 3 can be to constitute the section bar that is slidingly connected with steel tubes; Sleeve pipe 2 can also be the section bar (as section bars such as channel-section steels) of open architecture, and slide bar 3 is section bars such as the channel-section steel that can be nested with sleeve pipe 2 or I-steel.Front slide 1 is fixed 1 sleeve pipe 2, fixes 1 slide bar 3 on the tail skid 4, respectively 1 of promptly described sleeve pipe 2 and slide bar 3.In order to reduce the frictional resistance between sleeve pipe 2 and the slide bar 3, between sleeve pipe 2 and the slide bar 3 ball can be set, also available roller of ball and roller substitute, and between promptly described sleeve pipe 2 and the slide bar 3 ball are arranged.Between front slide 1 and the tail skid 4 back-moving spring is arranged, back-moving spring can reset after moving in that front slide 1 and tail skid 4 are relative.Back-moving spring uses tension spring, and back-moving spring can be installed in the sleeve pipe 2, and an end of back-moving spring passes sleeve pipe 2 and is connected on the front slide 1, and the other end of back-moving spring connects slide bar 3.Slide bar 3 can be a hollow pipeline.Tail skid 4 has propulsive mechanism.Described propulsive mechanism is that promotion front slide 1 and tail skid 4 are proal, operator's both feet stand on front slide 1 and the tail skid 4, can make front slide 1 and tail skid 4 produce relative motion by pedaling tail skid 4, under the effect of propulsive mechanism, front slide 1 and tail skid 4 can travel forward.Described propulsive mechanism can have following 2 kinds of embodiments:

First kind of propulsive mechanism.Described propulsive mechanism is the brake block 400 on the tail skid 4, and tail skid 4 is the tiltable structure.At the fixing brake block 400 of the reverse side of tail skid 4, brake block 400 is fixed on a side of tail skid 4, brake block 400 can use material manufacturings such as plastics or elastomeric material, for the ease of changing brake block 400, brake block 400 constitutes separable structure with tail skid 4, and brake block 400 uses screw to be fixed on the tail skid 4.Tail skid 4 is the tiltable structure.Referring to Fig. 4.The tiltable structure of tail skid 4 is such: 1 pulley 5 is installed on the tail skid 4, and sleeve pipe 2 is a pipe, and slide bar 3 is a round bar, and sleeve pipe 2 kinks are rotatable on slide bar 3; 8 centimetres of the diameters of rear wheel 5, the height of brake block 400 are 6 centimetres, when tail skid 4 is placed on ground and is the level of state, and overhead 2 centimetres of brake block 400.When tail skid 4 persons of being operated were pedaled and tilted, brake block 400 can land, thereby front slide 1 is travelled forward; When tail skid 4 recovers level, but brake block 400 built on stilts.

Second kind of propulsive mechanism.Described propulsive mechanism is the pulley 5 of band freewheel clutch on the tail skid 4.Freewheel clutch can be installed in the pulley 5 on the tail skid 4, and freewheel clutch and pulley 5 constitute integrative-structures, and pulley 5 is fixed on the tail skid 4 by freewheel clutch, and pulley 5 can only one-directional rotation.

Described front slide 1 is provided with steering handle, and front slide 1 connects pulley 5 by steering handle.Front slide 1 is provided with steering handle can become scooter.Steering handle is a prior art, can use the steering handle on the existing scooter, and steering handle connects pulley 5, and steering handle is rotatably connected by Bearning mechanism and front slide 1 formation.
