Description

Height-adjustable's rack case

Technical Field

The utility model relates to a rack box, concretely relates to stop gear on scalable corner post.

Background

A height-adjustable rack box is available for rolling wheel type or crawler type equipment. As shown in fig. 1, the tank is composed of a base frame 1, an end frame 2, and a diagonal brace 3. And end frame receiving grooves are formed in two ends of the underframe. The end frame is of a gantry structure, and the height of the end frame at least one end is adjustable. The end frames are hinged to two ends of the underframe and can be folded towards the inside of the box. The end frames are folded and hidden in the end frame receiving grooves at the end parts of the underframe. When the end frame is vertical, the wheeled or tracked equipment can pass through the end frame gantry from one end of the underframe by means of an auxiliary ramp, so that the rolling requirement is met. The disadvantage of this solution is that there is no stop mechanism on the telescopic corner post. This leads to two problems: (1) it is difficult to control the corner post extension stroke. (2) The fixing bolts on the corner posts are difficult to install and disassemble.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a height-adjustable rack box.

The technical scheme of the utility model is that:

a height-adjustable rack box is characterized by comprising an underframe, end frames and inclined struts, wherein end frame receiving grooves, outer hinges and inclined strut outer hinges are arranged at two ends of the underframe;

the end frame at least one end of the rack box is adjustable in height, the end frame with the adjustable height is of a gantry structure and comprises an end frame top beam, an outer corner column, an inner corner column and a fixed bolt, one end of the outer corner column is fixed on the end frame top beam, the other end of the outer corner column is an open end, one end of the inner corner column is connected with the inner hinge, the other end of the inner corner column is nested in the open end of the outer corner column, the outer corner column and the inner corner column form a telescopic corner column structure, and the inner corner column and the outer corner column are connected through the fixed bolt; the outer corner post is provided with a guide groove, and the inner corner post is provided with a limiting pin. When the corner post moves in a telescopic way, the limiting pin slides in the guide groove, so that the corner post limiting mechanism is formed.

The utility model discloses following beneficial effect has:

the utility model discloses rack box end frame is planer-type structure, and the end frame corner post of at least one end is scalable, height-adjustable promptly. When the roller mounting is carried out, the end frame is erected, the corner columns of the end frame extend, the gantry height rises along with the erection of the end frame, and more vehicle types can directly pass through the end frame gantry. When the box is folded and recovered, the corner posts of the end frame retract, the height of the end frame descends along with the corner posts, and the folded end frame is accommodated in the accommodating groove in the bottom frame. Because the telescopic corner post is provided with the limiting device, the stroke of the telescopic corner post is easy to control in the telescopic process of the corner post, and meanwhile, the installation and the disassembly of the fixed bolt are convenient.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 2, the platform box is composed of a base frame 1, a height-adjustable end frame 20 and a diagonal brace 3. The height-adjustable end frame 20 is of a gantry type structure and is hinged to the end part of the underframe through a hinge device. The height adjustable end stile 20 may be a box-in stand and have a height adjustable feature. The end frame with reduced height can be hidden in the end frame accommodating groove at the end part of the bottom frame after being folded. One end of the inclined strut 3 is hinged on the bottom frame, and the other end of the inclined strut is hinged in the end frame corner column.

As shown in fig. 3, the base frame 1 is provided at both ends thereof with end frame receiving grooves 11, outer hinges 12, and sprag hinge points 13.

As shown in fig. 4, the height adjustable end frame 20 is composed of an end frame top beam 21, an outer corner post 22, an inner corner post 23, and a fixing pin 24. One end of the outer corner post 22 is fixed on the end frame top beam 21, and the other end is an opening end. One end of the inner corner post 23 is connected with the inner hinge, and the other end is nested in the opening end of the outer corner post 22. The outer corner post 22 and the inner corner post 23 form a telescopic corner post structure, and the inner corner post and the outer corner post are connected through a fixing bolt 24.

As shown in fig. 5a, 5b and 5c, the inner corner post is provided with a guide groove 221. And a limiting pin 231 is arranged on the outer corner post. When the corner post is extended or retracted, the stopper pin 231 slides in the guide groove 221, thereby constituting a corner post stopper mechanism.

As shown in fig. 6, the telescoping corner post is in an extended position with the end frame height raised.

As shown in fig. 7, the retractable corner post is in a shortened state with the end frame height in a lowered state.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
