Abstract
The utility model discloses a kind of quick locking and releasing structure of hand barrow, comprise: upper spider and lower bearing bracket, upper spider one end is equipped with brake lever, the other end is fixed with snap close, and described snap close is connected by zip with between brake lever, and described lower bearing bracket is fixed with U-shaped pin, when the dead bolt of described snap close extends below U-shaped pin, upper spider is connected for locking with lower bearing bracket, and bolt retraction departs from U-shaped pin and is connected, and upper spider and lower bearing bracket are releasing structure.By the way, the utility model achieves Quick fastening and the function discharging upper spider and lower bearing bracket two design of parts fast, solves difficult release or the problem by several step ability releasing structure, thus improves work efficiency, save manpower, reduce productive costs.
Description
Technical field
The utility model relates to hand barrow field, particularly relates to a kind of quick locking and releasing structure of hand barrow.
Background technology
Quick release between the upper spider of existing hand barrow and lower bearing bracket and Quick fastening need several step just can complete, inefficiency, and human resources consumption is large, improves productive costs.
Utility model content
For solving the problems of the technologies described above, the utility model mainly provides a kind of can solve quick locking and the releasing structure that could be locked and discharge the hand barrow of the problem of upper spider and lower bearing bracket by several step.
The technical scheme that the utility model adopts is: the quick locking and the releasing structure that provide a kind of hand barrow, comprise: upper spider and lower bearing bracket, upper spider one end is equipped with brake lever, the other end is fixed with snap close, and described snap close is connected by zip with between brake lever, and described lower bearing bracket is fixed with U-shaped pin, when the dead bolt of described snap close extends below U-shaped pin, upper spider is connected for locking with lower bearing bracket, and bolt retraction departs from U-shaped pin and is connected, and upper spider and lower bearing bracket are releasing structure.
In the utility model preferred embodiment, described snap close is fixed on upper spider by cross recess pan bolt and hexagon nut with flange.
In the utility model preferred embodiment, the face, oblique angle of described pin tongue contacts with the hollows of U-shaped pin.
In the utility model preferred embodiment, described zip one end is elbow end, and described elbow end penetrates in bonnet lock hole, and the other end is arranged in the spacing hole of brake lever.
In the utility model preferred embodiment, described dead bolt is connected with retracing spring.
The beneficial effects of the utility model are: the utility model achieves Quick fastening and discharges the function of upper spider and lower bearing bracket two design of parts fast, solve difficult release or the problem by several step ability releasing structure, thus improve work efficiency, save manpower, reduce productive costs.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of preferred embodiment when discharging in the quick locking of the utility model hand barrow and releasing structure;
Fig. 2 is the structural representation of preferred embodiment when locking in the quick locking of the utility model hand barrow and releasing structure;
Fig. 3 is the quick locking of the utility model hand barrow and the exploded view of releasing structure.
In accompanying drawing, the mark of each parts is as follows: 1, brake lever, and 2, upper spider, 3, hexagon nut with flange, 4, snap close, 5, cross recess pan bolt, 6, lower bearing bracket, 7, zip, 8, U-shaped pin.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 2 and Fig. 3, the utility model embodiment comprises:
The quick locking of hand barrow and a releasing structure, as shown in Figure 3, comprising: upper spider 2 and lower bearing bracket 6, and upper spider 2 one end is equipped with brake lever 1, and the other end is fixed with snap close 4.Described brake lever 1 is provided at the end of frame, facilitates people's manual manipulation.
Described snap close 4 is fixed on upper spider 2 by cross recess pan bolt 5 and hexagon nut with flange 3.
Described snap close 4 is connected by zip 7 with between brake lever 1, and described zip 7 one end is elbow end, and described elbow end penetrates in snap close 4 hole, and the other end is arranged in the spacing hole of brake lever 1.
Described lower bearing bracket 6 is fixed with U-shaped pin 8, and when the dead bolt of described snap close 4 extends below U-shaped pin 8, upper spider 2 is connected for locking with lower bearing bracket 6, and bolt retraction departs from U-shaped pin 8 and is connected, and upper spider 2 and lower bearing bracket 6 are releasing structure.
Main operational principle is: when upper spider 2 moves down into certain position, the face, oblique angle of dead bolt contacts with U-shaped pin 8 hollows, the face, oblique angle of dead bolt and U-shaped pin 8 hollows all possess the effect of guiding, and dead bolt is under the retracing spring of inside simultaneously, and dead bolt can stretch out and compress into, be under pressure contraction, when locking toward when coming downwards to the below of U-shaped pin 8, dead bolt is released due to pressure, relies on spring automatically to return to original position, now reach the state of quick locking, as shown in Figure 2.
When depressing the handle of brake lever 1, because snap close 4 is connected with brake lever 1 by zip 7, when zip 7 applies pressure shortening by brake lever 1, dead bolt is subject to the pulling force of zip 7 and shrinks, thus reaches the state of release fast, now can will upper spider 2 move, as shown in Figure 1.
The utility model achieves Quick fastening and discharges the function of upper spider 2 and lower bearing bracket 6 two design of parts fast, solve difficult release or the problem by several step ability releasing structure, thus improve work efficiency, save manpower, reduce productive costs.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; 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.
