Description

TECHNICAL FIELD

[0001] The present application relates to the field of damping device, especially to a quick installation damping assembly and tail wheel thereof. BACKGROUND

[0002] When the pulley of the damping assembly is used as an upper pulley, in order to facilitate the installation, disassembly and subsequent maintenance of the damping slider, a maintenance opening is usually formed on the suspension rail, and the damping assembly is installed or disassembled through the maintenance opening and the suspension rail.

[0003] Therefore, due to the size of the maintenance opening, the operation of the damping assembly is not convenient when it is installed or disassembled with the suspension rail, which reduces the work efficiency of installation or disassembly, and consumes more manpower, material resources and time cost; in addition, the setting of the maintenance opening reduces the overall strength of the suspension rail, which is not conducive to the long-term use of the suspension rail. SUMMARY

[0004] In order to overcome at least one of the defects of the prior art, the present application provides a quick installation damping assembly and tail wheel thereof.

[0005] The technical scheme adopted by the present application to solve the problems is:

[0006] The first connecting piece;

[0007] The pulley seat;

[0008] The first connecting piece is movably arranged on the pulley seat and can adjust the relative position in the width direction of the pulley seat, and the first connecting piece is provided with a first pulley.

[0009] Further, the first connecting piece comprises a rotating piece and a first wheel seat, both ends of the rotating piece are rotatably connected with the pulley seat and the first wheel seat respectively, so as to adjust the relative position of the first wheel seat in the width direction of the pulley seat, and the first pulley is arranged on the first wheel seat.

[0010] Therefore, by adjusting the relative distance between the first connecting piece and the outer side of the pulley seat, the overall size of the first connecting piece and the pulley seat in the width direction of the pulley seat is reduced, so that the first connecting piece and the pulley seat can be installed or removed from the strip-shaped slot below the suspension rail, thereby realizing the quick installation or disassembly of the tail wheel and the suspension rail.

[0011] Further, a reset device is also included, which is arranged on the pulley seat and acts on the connection between the rotating piece and the pulley seat, so as to push the rotation of the rotating piece to push the first wheel seat away from the middle part of the pulley seat in the width direction of the pulley seat.

[0012] Therefore, before the tail wheel components are installed into the trolley rail, the first wheel seat is pushed to the middle of the pulley seat in the width direction of the pulley seat, at this time the reset device is in a compressed state, then the tail wheel components are installed into the trolley rail, and then the reset device pushes the first wheel seat to the direction away from the middle of the pulley seat in the width direction of the pulley seat, thereby automatically clamping the first pulley in the trolley rail.

[0013] Further, the reset device is a torsion spring.

[0014] Therefore, the torsion spring has the characteristics of simple structure and convenient use.

[0015] Further, the pulley seat is provided with a first fixing hole, and a fixing member passes through the first fixing hole to fix the first wheel seat to the pulley seat.

[0016] The fixing member fixes the first wheel seat to the pulley seat, further improving the stability of the overall structure of the tail wheel.

[0017] Further, it further comprises a second connecting member, the second connecting member comprises a second wheel seat, the second wheel seat is detachably connected with the first wheel seat, and the second wheel seat is provided with a second pulley.

[0018] Therefore, the detachable connection of the second wheel seat and the first wheel seat facilitates the installation and disassembly between the tail wheel components.

[0019] Further, it further comprises a plug-in part for plug-in fixing of the first wheel seat and the second wheel seat.

[0020] Therefore, the plug-in part can plug-in fix the first wheel seat and the second wheel seat, and the plug-in fixing of the first wheel seat and the second wheel seat effectively enhances the integrity between the first pulley and the second pulley, thereby ensuring the synchronicity and stability of the first pulley and the second pulley during rolling.

[0021] Further, the plug-in part comprises a plug-in protrusion and a plug-in groove, the plug-in protrusion and the plug-in groove are respectively arranged on the first wheel seat and the second wheel seat, and the plug-in protrusion is plugged into the plug-in groove to connect the first wheel seat and the second wheel seat.

[0022] Therefore, the specific way of plug-in of the plug-in part is the plug-in of the plug-in protrusion and the plug-in groove, the plug-in protrusion and the plug-in groove have simple structure and simple and fast assembly method, which is more conducive to the plug-in operation of the first wheel seat and the second wheel in the trolley rail and improves the installation or disassembly efficiency.

[0023] Further, the second wheel seat is provided with a mounting hole for plug-in of an external tool.

[0024] Therefore, when the second wheel seat and the second pulley need to be installed into or taken out of the track, due to the limited space in the track, an external tool can be inserted into the mounting hole to install or take out the second wheel seat and the second pulley.

[0025] Further, the pulley seat is provided with a second fixing hole, and the fixing member passes through the second fixing hole to fix the second wheel seat to the pulley seat.

[0026] The fixing member fixes the first wheel seat to the pulley seat, so that the first wheel seat can be kept in the middle of the pulley seat during installation, and the fixing member fixes the second wheel seat to the pulley seat, further improving the stability of the overall structure of the tail wheel.

[0027] A quickly-installed damping assembly comprises a damping body and a tail wheel, and the pulley seat is connected to the damping body.

[0028] Therefore, the damping assembly with the tail wheel has the characteristics of quick installation or disassembly of the track.

[0029] Further, the pulley seat is detachably connected to the damping body.

[0030] The detachable connection between the pulley seat and the damping body facilitates the installation and disassembly of the components.

[0031] A quickly-installed damping assembly comprises:

[0032] a damping body;

[0033] a first connecting member movably arranged on the damping body and adjustable in the relative position in the width direction of the damping body, and the first connecting member is provided with a first pulley.

[0034] Therefore, the tail wheel with the damping body can be directly connected without the pulley seat, reducing the use of components and thus reducing the cost.

[0035] In summary, the quickly-installed damping assembly and the tail wheel thereof provided by the present application have the following technical effects:

[0036] 1. The first connecting piece can be adjusted in the relative position in the width direction of the damping body, which can realize the overall width adjustment of the damping assembly, the first connecting piece and the damping assembly body can be directly passed through the strip-shaped slot below the suspended rail and installed in the suspended rail when the overall width of the damping assembly is minimum, then the first connecting piece is adjusted so that the overall width of the damping assembly reaches maximum, so as to limit the first connecting piece and the damping assembly body in the suspended rail, and the above-mentioned, since the damping assembly can be directly passed through the strip-shaped slot below the suspended rail and installed in the suspended rail, no maintenance opening needs to be additionally arranged on the suspended rail, thereby avoiding the problem of the overall strength reduction of the suspended rail caused by the maintenance opening.

[0037] 2. The first connecting piece can be adjusted in the relative position in the width direction of the damping body, which can realize the overall width adjustment of the damping assembly, the first connecting piece and the damping assembly body can be directly passed through the strip-shaped slot below the suspended rail and installed in the suspended rail when the overall width of the damping assembly is minimum, then the first connecting piece is adjusted so that the overall width of the damping assembly reaches maximum, so as to limit the first connecting piece and the damping assembly body in the suspended rail, and the above-mentioned, since the damping assembly can be directly passed through the strip-shaped slot below the suspended rail and installed in the suspended rail, no maintenance opening needs to be additionally arranged on the suspended rail, thereby avoiding the problem of the overall strength reduction of the suspended rail caused by the maintenance opening.
