Description

The hand brake type case and bag

Technical field

The utility model relates to a kind of hand brake type case and bag, belongs to field of mechanical technique.

Background technology

At present, the case and bag that have roller are used widely, the situation that still can occur rolling voluntarily at needs roller in the stopping time.For prevent case and bag from line slip, the case and bag that have are provided with brake gear, can the wheel of case and bag is static by brake function.But, having mode that the case and bag of brake gear step on by pin in the market and control wheel and realize opening and closing, its brake function operation is very inconvenient and loaded down with trivial details.

The utility model content

The utility model technical problem to be solved provides a kind of hand brake type case and bag, the mode that replaces pin to step on control the brake gear of case and bag roller startup, close, make operation simpler, convenient.

For solving the problems of the technologies described above; The utility model provides a kind of hand brake type case and bag, comprises shell, pull bar, pull bar handgrip, wheel, it is characterized in that; Also comprise be located on the shell, the button assembly of pull bar handgrip below; Said button assembly is provided with that button is removed in the brake tightening up, loosen of control brake cable and brake starts button, and it is inner that said brake cable one end is positioned at said button assembly, the other end and the brake block interlock that is located at the wheel next door.

Comprise the connecting rod that starts the button interlock with brake in the said button assembly, an end of said brake cable is arranged in the groove of said interlinking lever end.

Said brake cable around a runner clockwise or rotate counterclockwise.

Button and brake are removed in said brake, and to start button adjacent, and the bottom all is arranged in the said button assembly, and said brake is removed the button bottom and had an inclined-plane, one have the interior inclined-plane corresponding with said inclined-plane positioning bead be arranged at said brake and remove bottom the button; Said positioning bead is driven by a positioning bead stage clip and starts button with said brake and lean on mutually, said brake start side bottom the button have one can locate said positioning bead groove.

Be provided with back-moving spring between said brake startup button and said connecting rod.

The other end of said brake cable is connected with an end of a connecting plate; Said connecting plate rotates around the rotating shaft that is positioned on its center line; When said connecting plate rotated, the other end of said connecting plate can be in the position that presses down said brake block and said wheel CONTACT WITH FRICTION or be in and lift the position that said brake block separates with said wheel.

The beneficial effect that the utility model reached:

The brake that the hand brake type case and bag of the utility model adopt the brake startup button on the hand button assembly and the releasing button that brakes to control the case and bag roller starts, closes, and button assembly is arranged at the below of pull bar handgrip, and is simple, convenient.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.

Like Fig. 1, shown in Figure 2; The hand brake type case and bag comprise shell 1, pull bar 2, pull bar handgrip 21, wheel 3; Also comprise the button assembly 4 that is located at pull bar handgrip 21 belows; Button assembly 4 is provided with brake and removes button 5 and brake startup button 6, button assembly 4 is connected the action control that realizes brake with wheel 3 by brake cable 7.

Below in conjunction with Fig. 3, Fig. 4 and Fig. 5, the detailed structure of hand brake type case and bag and startup, releasing brake operation are described.

Non-braking state: when brake startup button 6 was in like Fig. 3 state, brake block 8 was in the state of upspringing, and did not interfere with wheel 3, and wheel 3 can freely rotate.

Braking state:

Press down brake and start button 6 to position as shown in Figure 4, positioning bead 9 ejects left under 10 effects of positioning bead stage clip, snaps in brake and starts in button 6 grooves, makes it the location.Brake is removed button 5 bottoms and is had an inclined-plane 51, comprises an interior inclined-plane corresponding with inclined-plane 51 in the positioning bead 9, make positioning bead 9 eject left the time, under interior inclined-plane promotes the cooperation on inclined-plane 51, the releasing button 5 that the brakes ejection that can move upward automatically.

When brake startup button 6 presses down; Meeting compression spring 11 and drivening rod 12 move downward; One end of brake cable 7 is stuck in the groove of connecting rod 12 ends and moves downward with connecting rod 12, and brake cable 7 wheel 13 that under the drive of connecting rod 12, rotates tightens up action clockwise.Near the other end that brake cable 7 is positioned at the wheel is connected with a connecting plate 14, when brake cable 7 is tightened up motion clockwise, will drive connecting plate 14 and clockwise rotate around its rotating shaft 15; Connecting plate 14 left ends move upward; And its right-hand member moves downward, and depresses brake block 8, and brake block 8 is pressed back and wheel 3 CONTACT WITH FRICTION; Move interference, realize brake function.

Release the brake Status: In brake boot state, pressing down the brake release button 5, the brake release button 5 pressed process, the bevel 51 to promote the positioning beads 9 Inner Bevel, the positioning positioning beads beads 9 compression spring 10 and right movement, positioning beads 9 from brakes start button 6 slot exit, brake start button 6 in the restoring force of the spring 11 under the action of the pop-up, while driving rod 12 upward movement.When connecting rod 12 moves upward, brake cable 7 one ends that are stuck in its end grooves are moved upward thereupon, brake cable 7 wheel 13 that under the drive of connecting rod 12, rotates carries out counterclockwise loosening up.Brake cable 7 moves downward with the other end that connecting plate 14 is connected, and connecting plate 14 is rotated counterclockwise around its rotating shaft 15, and connecting plate 14 left ends move downward; And its right-hand member moves upward, and pushes down brake block 8 no longer downwards, and brake block 8 upwards lifts under the returning spring effect automatically; Do not contact with wheel 3; Do not move interference with wheel 3, the brake closed condition is promptly got back in wheel 3 rotation that affranchises.

Button assembly 4 inner link 12, runner 13 and brake cable 7 are symmetrical set, and 2 brake cable 7 are connected to 2 wheels 3 respectively, realize that simultaneously brake to wheel 3 starts and removes.

The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection domain of the utility model.
