Abstract
The utility model discloses a U-shaped lock type opening and closing mechanism of a dumper packing case tail door. The U-shaped lock type opening and closing mechanism comprises a base sleeve, a fixing sleeve and a U type safety pin, wherein a hoop and the base sleeve are fixed on a stand column on the side of the dumper packing case tail door, the fixing sleeve is fixed on the dumper packing case tail door, one end of the U type safety pin is matched with the base sleeve, the other end of the U type safety pin is matched with the fixing sleeve, and opening and closing of the packing case tail door are achieved through pulling-out and inserting-in of the U type safety pin. The U-shaped lock type opening and closing mechanism further comprises the hoop and a split pin, wherein the hoop and the base sleeve are fixed to the same stand column, and the split pin is arranged at the end, inserted into the base sleeve, of the U type safety pin. Under the condition that precise workpiece manufacturing and special investment are not needed, the facts that the tail door is effectively locked when daily cargos are loaded on the packing case and the tail door can be freely closed or opened when hoisting is carried out are guaranteed. The opening and closing mechanism of the dumper packing case tail door is not only convenient to operate but also easy to manufacture and high in strength (because welding binding faces are long), and resolves a series of problems that an opening and closing mechanism normally used for a light-duty automobile and a truck at present is complex in structure and high in cost and easily causes blocking.
Description
Technical field
The utility model relates to gently, microcaloire car self-unloading cargo box structure, is specifically related to a kind of capacity of the tipping body tail-gate U-shaped locking-type mechanism for opening/closing.
Background technology
At present, commonly used light, microcaloire car capacity of the tipping body tail-gate mechanism for opening/closing mainly contains three kinds of drag hook type, lock posture and rod-pulling types.Wherein, drag hook type forms with locking and the relieving of latch and moves mainly by the drag hook upset, reaches the purpose that the back door opens and closes, and is easy to operate, can effectively turn round.But when latch and back door were welded to connect, face of weld was little, weak strength, welding operation difficulty are big, and the latch cantilever is long simultaneously, and latch easily deforms in actual use, even fractures; The lock posture is bent the locking of lock frame and buckle and is decontroled action by straight, reach the purpose that the back door opens and closes, but because straight curved lock frame is when opening, often whirlpool down downwards owing to the vibration of gravity or container lifting, thereby the keying at influence even interference back door, bring inconvenience for operation and use, seldom producer uses this structure; Rod-pulling type is by pull bar (the employing hinge that has) folding and unfolding, briquetting is compressed and decontrols the back door, reaches the purpose that the back door opens and closes.Container of engineering dump truck use at present is comparatively general, but the manufacturing cost height, mechanism's relative complex, if poor fit (stuck) between structure, the back door can not effectively be opened when easily causing the container lifting, thereby accidents caused.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of easy to operate, the non-damageable capacity of the tipping body tail-gate of structure U-shaped locking-type mechanism for opening/closing is provided.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of capacity of the tipping body tail-gate U-shape lock formula mechanism for opening/closing, it is characterized in that: this mechanism comprises cover for seat, fixed cover and U-shaped latch, wherein, cover for seat is fixed on the column of capacity of the tipping body, fixed cover is fixed on the capacity of the tipping body tail-gate, one end of U-shaped latch cooperates with cover for seat, and the other end cooperates with fixed cover.
Further, the head that described U-shaped latch inserts cover for seat one end is provided with pin-and-hole, construction opening pin in the pin-and-hole.
Further, described capacity of the tipping body tail-gate U-shape lock formula mechanism for opening/closing also comprises clip, and clip and cover for seat are fixed on the same column of capacity of the tipping body.
Compared with prior art, one of the beneficial effects of the utility model are: need not under accurate product and the special situation about dropping into, when guaranteeing the daily loading of container, tail-gate is effectively locked; During lifting, tail-gate is opened (upset) freely.Make that container tail-gate mechanism for opening/closing is not only easy to operate, and make easily, intensity high (welding applying face length), solved at present slight, card Vehicle tipping container mechanism for opening/closing complex structure commonly used, cost higher, easily cause stuck serial problem.
Description of drawings
Fig. 1 shows according to structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
A kind of capacity of the tipping body tail-gate U-shape lock formula mechanism for opening/closing, comprise clip 1, cover for seat 2, fixed cover 3 and U-shaped latch 4, wherein, clip 1 and cover for seat 2 are fixed on the column on capacity of the tipping body tail-gate limit, fixed cover 3 is fixed on the capacity of the tipping body tail-gate, one end of U-shaped latch 4 cooperates with cover for seat 2, and the other end cooperates with fixed cover 3, by the keying of extracting and inserting realization container tail-gate of U-shaped latch 4.When an end of U-shaped latch inserted the cover for seat other end and inserts fixed cover, the container tail-gate was locked on the column on its limit, realizes closing of container tail-gate; When U-shaped latch appoint one or both ends to be in to extract state the time, the container tail-gate is realized opening, can be stuck in a certain end of U-shaped latch in the clip 1 this moment.
The head that described U-shaped latch inserts cover for seat 2 one ends is provided with pin-and-hole, construction opening pin 5 in the pin-and-hole.This structure Design realizes the flexible connection of U-shaped latch 4 and cover for seat 2, also can not drop out from cover for seat 2 when extracting state when U-shaped latch 4 is in, and improves simple operation.
The working process of described capacity of the tipping body tail-gate U-shape lock formula mechanism for opening/closing is: first a certain end with U-shaped latch 4 inserts in the cover for seat 2 and installs spring cotter 5; When closing the container tail-gate, U-shaped latch 4 is mentioned along cover for seat 2, the other end of U-shaped latch inserts fixed cover 3, as shown in Figure 1; When opening the container tail-gate, U-shaped latch 4 is rotated to an angle after cover for seat 2 is mentioned, the elbow of U-shaped latch is partly snapped in the clip 1.
Although be described with reference to the utility model of best interpretations embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and embodiment will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to constituent elements and/or the layout of subject combination layout.Except modification that constituent elements and/or layout are carried out with improving, to those skilled in the art, other purposes also will be tangible.
