Abstract
The utility model discloses an automatic wheel brake system which comprises a wheel body, a support, a central shaft and a plug pin locking device. The wheel body comprises a central hole, a spoke support, a wheel face groove and a plug pin hole, the central hole of the wheel body is connected with the support through the central shaft, the central shaft comprises an end bolt, a nut and a central round rod, the plug pin locking device is arranged on the top of the support, and comprises a spring, a cylindrical pin, a positioning ring and a spring limiting ring, and the cylindrical pin moves up and down through the positioning ring in the vertical direction. According to the mode, the automatic wheel brake system is used in cooperation with a brake cable, and is easy and convenient to operate, rapid in response, good in braking effect, high in stability, and capable of being widely applied to trolleys in supermarkets, warehouses and the like.
Description
Technical field
The utility model relates to parking system design field, particularly relates to a kind of wheel automatic parking system.
Background technology
Hand barrow is a kind of common transportation means, because operation is light, it is flexible to turn to, comparatively extensive in the use in the places such as warehouse, supermarket.
The wheel of hand barrow is less, and part vehicle do not have parking system, to user, brings certain trouble or even danger, and the part hand barrow that contains parking system, and its parking system is rubber friction braking, and parking performance is weak and effect is stable not.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of wheel automatic parking system, can automatic parking in the time of parking, and stable performance, simple to operate, parking is effective.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of wheel automatic parking system is provided, comprise: wheel body, support, center shaft and latch latching device, described wheel body comprises centre hole, vertically hung scroll supports, wheel face groove and pin hole, the centre hole of described wheel body is connected by center shaft with supporting, described center shaft comprises end bolt, nut and middle round bar, described latch latching device is positioned at the top of support, described latch latching device comprises spring, straight pin, nest, spring limit coil, described straight pin is lower mobile in the vertical direction by nest.
In preferred embodiment of the utility model, the centre hole of described wheel body comprises the bearing in hole.
In preferred embodiment of the utility model, described nest is welded on support, top.
In preferred embodiment of the utility model, the diameter of described straight pin is less than the diameter of pin hole.
The beneficial effects of the utility model are: a kind of wheel automatic parking system that the utility model is pointed out, be arranged on the wheel position of hand barrow, by hand barrow, push away the latch latching device that brake cable on handle is connected to wheel automatic parking system, when moving, go-cart holds brake, straight pin in latch latching device rises, wheel rotates freely, when stopping, hand unclamps naturally, straight pin is promoted to quickly fall in the pin hole of wheel body by spring, stop the running of wheel, simple to operate, reaction is fast, parking is effective, stable performance, the anti-car that automatically slips.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of wheel automatic parking system one preferred embodiment of the present utility model;
Fig. 2 is the left view of Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, wheel body, 2, support, 3, center shaft, 4, latch latching device.
The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, the utility model embodiment comprises:
A kind of wheel automatic parking system, comprise: wheel body 1, support 2, center shaft 3 and latch latching device 4, described wheel body 1 comprises centre hole, vertically hung scroll support, wheel face groove and pin hole, the centre hole of described wheel body 1 is connected by center shaft 3 with support 2, described center shaft 3 comprises end bolt, nut and middle round bar, described latch latching device 4 is positioned at the top of supporting 2, described latch latching device 4 comprises spring, straight pin, nest, spring limit coil, and described straight pin is lower mobile in the vertical direction by nest.
Further, the centre hole of described wheel body comprises the bearing in hole.
Further, described nest is welded on support, top.
Further, the diameter of described straight pin is less than the diameter of pin hole.
General hand barrow parking system adopts is the running that the friction force of sheet rubber stops wheel, due to skidding between wearing and tearing, wheel and the rubber of unstable, the rubber of rubber pressure, causes parking unstable properties, and effect is naturally poor.
A kind of wheel automatic parking system that the utility model is pointed out, be arranged on the bottom of hand barrow, by hand barrow, push away the latch latching device 4 that brake cable on handle is connected to wheel automatic parking system, when moving, go-cart holds brake, straight pin in latch latching device 4 rises, and wheel body 1 rotates freely, and in the time of parking, hand unclamps naturally, straight pin is promoted to quickly fall in the pin hole of wheel body by spring, stops the running of wheel.
In sum, a kind of wheel automatic parking system that the utility model is pointed out, coordinates brake cable to use, easy and simple to handle, be swift in response, parking is effective, stability is high, can be widely used in the hand barrow in the places such as supermarket, warehouse.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
