Description

Technical Field

[0001] The invention relates to the technical field of logistics and transportation, and in particular to a universal wheel for logistics equipment which is easy to replace. Background Art

[0002] A swivel wheel is a so-called movable caster, and its structure allows for 360-degree horizontal rotation. Casters are a general term, including movable casters and fixed casters. Fixed casters have no rotating structure and cannot rotate horizontally but only vertically. These two types of casters are generally used in combination. For example, a trolley has two fixed wheels in the front and two movable swivel wheels in the back near the push handles. Casters, as an important component of many handling tools, are not only walking parts, but also have the function of shock absorption, especially in logistics places with uneven ground conditions. The shock absorption effect of casters plays a key role in the quality of handling operations and the noise of the working environment.

[0003] After searching, Chinese patent number CN106626976A discloses a shock-absorbing universal wheel. Although it can facilitate the load-bearing of the caster and improve stability, its disassembly is cumbersome and requires repeated tightening of the bolts, which makes it inconvenient to replace the universal wheel for logistics equipment, thereby affecting the use of logistics equipment and causing the problem of device defects. Summary of the invention

[0004] The purpose of the present invention is to solve the defects in the prior art and to provide a universal wheel for logistics equipment which is easy to replace.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A universal wheel for logistics equipment that is easy to replace, includes a bracket and a rotating rod, the top surface of the rotating rod is provided with an embedded column, the outer surface of the embedded column is provided with an embedded groove, the embedded groove is embedded with an embedded rod, and a cavity one is provided in the embedded column, the top surface of the cavity one is rotatably connected with a screw rod, the outer surface of the screw rod is meshingly sleeved with a moving block, the outer surface of the moving block is hinged with an articulated rod, the other end of the articulated rod is hinged with a clamping rod, and a guide rod is provided through the moving block.

[0007] Furthermore, a magnetic block is fixedly connected to the top surface of the embedded column, a second cavity is opened at the top of the embedded rod, a clamping block is slidably sleeved on the top wall of the second cavity, a second spring is installed between the clamping block and the bottom surface of the second cavity, and a pull rod is fixedly connected to the side wall of the clamping block.

[0008] Through the above technical solution, the following technical effects can be achieved: the universal wheel on the logistics equipment does not need to repeatedly tighten the nut, making the disassembly and installation of the universal wheel easy, thereby simplifying the replacement of the universal wheel and avoiding affecting the use of the logistics equipment.

[0009] Furthermore, the bottom surfaces of the embedded rod and the screw rod are fixedly connected to the rotating rod, the cross section of the embedded groove is L-shaped, the two ends of the guide rod are respectively fixedly connected to the two ends of cavity one, and the clamping rod is slidably sleeved with the side wall of cavity one.

[0010] Furthermore, the embedded rods are evenly distributed about the central axis of the embedded column, the second cavity is T-shaped, the pull rod extends outside the embedded rod, and the pull rod is slidably sleeved with the second cavity, and the clamping block is clamped with the top surface of the embedded groove.

[0011] Furthermore, the clamping block and the pulling rod are each provided with one, and the circumference of the moving track of the clamping block is a multiple of the screw pitch.

[0012] Furthermore, a roller is hingedly connected to one end of the bracket, and a turntable is rotatably connected to the other end of the bracket, a fixed block is fixedly connected to the other side of the turntable, and a connecting rod is fixedly connected to the other side of the fixed block, and the connecting rod is slidably sleeved with the bottom surface of the rotating rod, and the outer surface of the rotating rod is respectively provided with embedding holes and sliding grooves, a slider is slidably sleeved in the sliding groove, a moving ring is fixedly connected to the end surface of the slider, and a bolt is meshed and sleeved on the outer surface of the moving ring, a telescopic rod is fixedly connected between the top surface of the fixed block and the inner top surface of the rotating rod, and a spring is slidably sleeved on the outer surface of the telescopic rod.

[0013] Through the above technical scheme, the following technical effects can be achieved: the fixed block on the connecting rod drives the turntable and the bracket to descend, thereby indirectly extending the height of the universal wheel, and then the bolt is rotated to make the bolt re-engage with the embedding hole to achieve the purpose of fixing the height of the universal wheel. At this time, the universal wheel can lift the logistics equipment to a specific height to avoid friction caused by contact between the logistics equipment and the ground. At the same time, the universal wheel can also be used in a variety of logistics equipment, expanding the scope of application.

[0014] Furthermore, the sliding block is fixedly connected to the side wall of the connecting rod, the moving ring is slidably sleeved with the outer surface of the rotating rod, and the bolt is engaged with the embedding hole.

[0015] Furthermore, the rotating rod fixes the connecting rod and the fixing block through a movable ring, bolts and embedded holes.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention drives the clamping block to separate from the top surface of the embedded groove by the pull rod, thereby releasing the fixation of the rotating rod and the embedded column, and then drives the moving block to move by the screw on the rotating rod, and the moving block cannot rotate due to the limit of the guide rod. Therefore, the moving block can only move vertically under the drive of the screw, so that the moving block drives one end of the hinged rod to descend, so that the other end of the hinged rod pulls the clamping rod to shrink into the cavity, so that the clamping rod is separated from the inner side wall of the installation groove reserved on the logistics equipment, thereby releasing the clamping connection of the embedded column, so that the embedded column can be pulled out of the installation groove. The purpose of disassembling the universal wheel for logistics equipment is achieved. When the universal wheel for logistics equipment needs to be installed, the embedded column is reinserted into the installation groove, and the magnetic block on the embedded column is engaged and adsorbed with the top surface of the installation groove, so that the embedded column cannot rotate, and then the above operation is repeated in reverse, so that the clamping rod is engaged with the inner wall of the installation groove again, and the embedded column is fixed to the rotating rod, so as to achieve the purpose of replacing the universal wheel on the logistics equipment. There is no need to repeatedly tighten the nut, which makes the disassembly and installation of the universal wheel simple, thereby simplifying the replacement of the universal wheel and avoiding affecting the use of the logistics equipment.

[0018] 2. The present invention disengages the bolt from the embedding hole by rotating the bolt on the movable ring, thereby releasing the fixation of the movable ring and indirectly releasing the fixation of the connecting rod and the fixed block. The connecting rod is then driven to extend out of the rotating rod by the slider on the movable ring, so that the fixed block on the connecting rod drives the turntable and the bracket to descend, thereby indirectly extending the height of the universal wheel. The bolt is then rotated to re-engage the bolt with the embedding hole to achieve the purpose of fixing the height of the universal wheel. At this time, the universal wheel can lift the logistics equipment to a specific height to avoid friction caused by contact between the logistics equipment and the ground. At the same time, the universal wheel can also be used with a variety of logistics equipment, thereby expanding the scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

A slider 8 is slidably sleeved in the slide groove 7, and a moving ring 9 is fixedly connected to the end surface of the slider 8. A bolt 10 is meshingly sleeved on the outer surface of the moving ring 9, and a telescopic rod 12 is fixedly connected between the top surface of the fixed block 4 and the inner top surface of the rotating rod 6. A spring 13 is slidably sleeved on the outer surface of the telescopic rod 12, and the slider 8 is fixedly connected to the side wall of the connecting rod 5, and the moving ring 9 is slidably sleeved on the outer surface of the rotating rod 6.
