Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention with the anti-toppling handle structure will be further described below by referring to the drawings of the specification and the specific embodiments.

Example 1

As shown in fig. 1 to 4, an anti-tipping handle structure includes a handle assembly and a pair of fixing assemblies arranged in mirror symmetry, wherein the handle assembly is fixedly connected with a container through the fixing assemblies.

The handle assembly comprises a cross beam 11 and two side beams 12 connected with the cross beam 11, wherein the side beams 12 are vertically connected with the cross beam 11, strip-shaped connecting holes 15 and open slots 14 are sequentially formed in the side beams 12, the connecting holes 15 are arranged on one side far away from the cross beam 11, and the openings of the open slots 14 are arranged on one sides of the side beams 12 close to a pin 22. When the handle assembly is rotated to the upright position, the pins 22 snap into the slots 14.

The fixing component comprises a mounting plate 21 connected with the wall of the container 3, a limiting piece 24 connected with the side wall of the mounting plate 21, a lock pin 22 and a rotating shaft 23 which are sequentially arranged on the front end surface of the mounting plate 21 from top to bottom.

The rotating shaft 23 penetrates through the connecting hole 15, the side beam 12 is connected with the mounting plate 21 through a nut, and the side beam 12 can rotate freely by taking the rotating shaft 23 as an axis.

When the handle assembly is vertically and naturally placed, the pin shaft 22 is contacted with one side wall of the open slot 14, which does not form a limiting bulge, and the rotating shaft 23 is contacted with one end of the connecting hole 15, which is close to the open slot 14;

when the handle assembly is lifted vertically, the pin 22 contacts with a side wall of the open slot 14 forming a limiting protrusion, and the rotating shaft 23 contacts with one end of the connecting hole 15 far away from the open slot 14.

The limiting member 24 is used for limiting the rotation position of the handle assembly, the limiting member may be set to be any structure capable of achieving a limiting function, such as an L shape or a straight shape, and the length of the portion of the limiting member 24 perpendicularly connected to the wall of the container 3 is greater than the maximum thickness of the mounting plate 21, and further, in order to ensure the stability of limiting, the length of the portion of the limiting member 24 perpendicularly connected to the wall of the container 3 is greater than the sum of the maximum thickness of the mounting plate 21 and the thickness of the side wall 21.

Example 2

Based on embodiment 1, in order to further ensure the stability of the handle assembly when the container is lifted, the side wall of the open slot 14 close to the connecting hole 15 forms a limiting protrusion 141 for limiting the falling-out of the pin 22. Furthermore, in order to facilitate the pin 22 to enter the opening groove 14, the limiting protrusion 141 is disposed to be inclined toward the inside of the opening groove 14 near the sidewall of the pin 22.

Example 3

Based on example 1, in order to further extend the application of the anti-tipping handle of the invention in automation, the end face of the cross beam 11 remote from the container 3 is provided with a connecting piece 13 which is convenient for the manipulator to grasp. The connecting piece 13 is of a T-shaped structure.

The working principle of the invention is as follows:

the mounting plate in the fixing component is used for being fixedly connected with the wall of the container. The side beam of the handle assembly is provided with a connecting hole and an open slot. When the handle is not used, the handle assembly is in a horizontal state under the limiting action of the limiting block, as shown in attached figure 2. When the handle assembly is in operation, rotating the handle assembly to a vertical position, wherein the handle assembly is under gravity, as shown in fig. 3; and further lifting the handle assembly, moving the handle assembly upwards until the lower semicircle of the connecting hole of the side beam of the handle assembly is contacted with the rotating shaft, and clamping the lock pin of the limiting protrusion of the open slot of the side beam of the handle assembly at the moment so as to realize the relative fixation of the handle assembly and the container, wherein the phenomenon of inclination or tipping caused by the rotation of the container around the rotating shaft can be effectively prevented as shown in the attached figure 4.

The working process of the invention is as follows:

when the handle assembly is laid down to the horizontal state, the handle assembly is supported and limited by the limiting part. When the handle assembly works, the handle assembly is rotated to be in a vertical state, at the moment, under the action of gravity, the upper semicircle of the connecting hole on the side beam of the handle assembly is contacted with the rotating shaft, and the opening of the open slot on the side beam of the handle assembly is flush with the height of the lock pin, as shown in the state of figure 3; the lifting handle is further lifted, the lifting handle assembly moves upwards until the lower semicircle of the connecting hole of the side beam of the lifting handle assembly is contacted with the rotating shaft, and the open slot of the side beam of the lifting handle assembly clamps the lock pin, so that the relative fixation of the lifting handle assembly and the container is realized, and the phenomenon of inclination or tipping caused by the rotation of the container around the rotating shaft can be effectively prevented.
