Summary of the invention
For between existing door-plate and floor, having gap, the utility model provides the joint closing device of a kind of.
To achieve these goals, the utility model is that the technical scheme that its technical problem of solution is taked is:
The joint closing device of a kind of, comprise the main body be fixed on door-plate, described main body is provided with an elongated slot, one end of elongated slot is groove, the other end of elongated slot is connected with an expansion link by back-moving spring, and expansion link is located in elongated slot, the end that expansion link is positioned at groove is the metal slippery fellow, be connected with at least two wire springs on described expansion link, described wire spring is movably connected on main body by revolving joint, and the lower end of wire spring is by the rivet joint close plate that has been movably connected.
Further, described metal slippery fellow is inclined-plane slippery fellow or spherical slippery fellow.
Further, the bottom of described joint close plate is provided with rubber weather strip.
Further, described wire spring is preferably two.
Further, described revolving joint is rivet, screw, nail or pin.
The beneficial effects of the utility model: the joint closing device of door provided by the utility model, can effectively fill the gap between door and floor, prevent that mouse, mosquitos and flies, worm ant from entering indoor; This joint closing device can be protected door preferably, prevents that door is damaged or scratch; The material of making this joint closing device is comparatively common and cheap, and product cost is low.
The accompanying drawing explanation
Fig. 1 is the utility model joint closing device structural representation.
The joint close view that Fig. 2 is joint closing device.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The joint closing device of a kind of as shown in Figure 1-2, comprise the main body 1 be fixed on door-plate, it should be noted that, described main body 1 is provided with an elongated slot 2, one end of elongated slot 2 is groove, the other end of elongated slot 2 is connected with an expansion link 4 by back-moving spring 3, and expansion link 4 is located in elongated slot 2, the end that expansion link 4 is positioned at groove is metal slippery fellow 5, be connected with at least two wire springs 6 on described expansion link 4, described wire spring 6 is movably connected on main body 1 by revolving joint 7, and the lower end of wire spring 6 is by the rivet joint close plate 8 that has been movably connected.
Further it should be noted that described metal foxy 5 is for inclined-plane slippery fellow or spherical slippery fellow.
Bottom that further it should be noted that described joint close plate 8 is provided with rubber weather strip 9.
Further it should be noted that described wire spring 6 is preferably two.
Further it should be noted that described revolving joint 7 is for rivet, screw, nail or pin.
When door is closed, the metal slippery fellow 5 of doorframe compression expansion link 4, expansion link 4 slides left and drives wire spring 6 upper ends and slides left together, the centre of wire spring 6 is owing to being movably connected on main body 1 by revolving joint 7, make the lower end of wire spring 6 move and drive joint close plate 8 downwards and move downward, thereby reach sealing effectiveness.
When door is opened, because doorframe is abandoned the pressure to expansion link 4 metal slippery fellows 5, expansion link 4 affects because of the elastic force of the back-moving spring 3 that is subject to left end, make expansion link 4 slide to the right, and slide to the right together in drive wire spring 6 upper ends, wire spring 6 bottoms drive joint close plates 8 move upward simultaneously, reach the unlatching effect.
Joint closing device provided by the utility model, can effectively fill the gap between door and floor, prevents that mouse, mosquitos and flies, worm ant from entering indoor; This joint closing device can be protected door preferably, prevents that door is damaged or scratch; The material of making this joint closing device is comparatively common and cheap, and product cost is low.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
