Description

Technical Field

[0001] This utility model relates to the field of caster technology, specifically to a high load-bearing caster. Background Technology

[0002] High-load-bearing casters are key load-bearing components in industrial equipment, warehousing and logistics, and heavy machinery. Existing heavy-duty casters generally adopt bolt-fastened or welded installation structures. When facing equipment maintenance, bearing replacement, or wheel wear, the disassembly process requires special tools and high-intensity operations, which is particularly difficult in narrow spaces or high-altitude operation scenarios. Furthermore, repeated disassembly and assembly can easily lead to stripped threads or structural deformation of the mounting base, thereby causing safety hazards. Therefore, a high-load-bearing caster is proposed. Utility Model Content

[0003] In view of the problems in the prior art, this utility model provides a high load-bearing caster.

[0004] The technical solution adopted by this utility model to solve its technical problem is a high load-bearing caster, including a connecting plate and a mounting plate. The bottom end of the connecting plate is fixedly connected to the caster. The connecting plate is arranged in a U-shape. A cavity is opened inside the connecting plate for the mounting plate to be installed and inserted. A spring cavity is opened inside the mounting plate. A spring is vertically installed inside the spring cavity. A limit plate is fixedly connected to the top end of the spring. The top end of the limit plate is fixedly connected to the bottom end of the limit rod. A through groove is opened at the top end of the connecting plate for the limit rod to be installed and inserted.

[0005] By adopting the above technical solution, the caster can be quickly installed through the modular connection between the connecting plate and the mounting plate. During assembly, only three steps are required: pressing the limit rod, pushing in the connecting plate, and pushing down the baffle. This can improve the speed of installation and disassembly of the caster, and the convenience of maintenance is significantly better than the traditional bolt fixing method.

[0006] Specifically, the top end of the mounting plate is fixedly connected to the bottom end of the support column, the top end of the support column is fixedly connected to the bottom end of the top plate, and threaded holes are provided at the four corners of the top plate for bolts to be screwed in.

[0007] By adopting the above technical solution, the top plate is fixed to the bottom of the mobile device through the threaded holes at its four corners. During operation, the bolts are inserted from the bottom of the top plate upwards through the threaded holes and then screwed into the pre-set mounting holes of the mobile device.

[0008] Specifically, positioning grooves are provided on both sides and the bottom surface of the mounting plate. The positioning grooves are used for the insertion of positioning strips, and the positioning strips are fixedly connected to the inner sides and the inner bottom surface of the connecting plate.

[0009] By adopting the above technical solution, the insertion process of the mounting plate and the connecting plate needs to be precisely guided by the positioning groove and positioning strip. The operator needs to strictly align the positioning strip on the inner side of the connecting plate with the positioning groove on the corresponding side of the mounting plate, thereby increasing the connection friction between the mounting plate and the connecting plate.

[0010] Specifically, two sliding grooves are provided on both sides of the support column and both sides of the mounting plate. The two sliding grooves are used for sliding installation of the sliders. One end of the two sliders is fixedly connected to one side of the baffle.

[0011] By adopting the above technical solution, the baffle achieves vertical sliding adjustment through the cooperation of the slider and the sliding groove. After the connecting plate and the mounting plate are inserted, the baffle is pushed down, and the sliders on both sides move down along the sliding grooves on the support and the mounting plate until the baffle can cover both sides of the connecting plate.

[0012] Specifically, the bottom end of the bolt contacts the top end of the connecting plate.

[0013] By adopting the above technical solution, after the connecting plate and the mounting plate are connected together, the bottom end of the bolt will abut against the top end of the connecting plate, thereby providing a function to prevent the bolt from coming loose.

[0014] Specifically, finger grooves are provided on both sides of the connecting plate, and the finger grooves are connected to the inside of the through groove.

[0015] By adopting the above technical solution, a finger can be inserted into the finger groove and pressed down on the limiting rod, so that the limiting rod is pressed into the interior of the mounting plate, which can push the connecting plate to separate the connecting plate and the mounting plate.

[0016] The beneficial effects of this utility model are:

[0017] The high load-bearing caster described in this utility model can be quickly installed through the modular connection between the connecting plate and the mounting plate. During assembly, only three steps are required: pressing the limit rod, pushing in the connecting plate, and pushing down the baffle. This can improve the speed of installation and disassembly of the caster, and the convenience of maintenance is significantly better than the traditional bolt fixing method.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As one embodiment of this utility model, such as Figures 1-4 As shown, the high-load-bearing caster of this utility model includes a connecting plate 2 and a mounting plate 3. The bottom end of the connecting plate 2 is fixedly connected to a caster 1. The connecting plate 2 is U-shaped and has a cavity 17 inside for the mounting plate 3 to be inserted. The mounting plate 3 has a spring cavity 12 inside and a spring 7 is vertically installed inside the spring cavity 12. The top end of the spring 7 is fixedly connected to a limiting plate 8. The top end of the limiting plate 8 is fixedly connected to the bottom end of a limiting rod 9. The top end of the connecting plate 2 has a through groove 10 for the limiting rod 9 to be inserted.

[0026] When using the connecting plate 2 and the mounting plate 3, the operator needs to slide the mounting plate 3 horizontally into the connecting plate 2 along the cavity 17. At this time, the operator needs to use their fingers to press the limiting rod 9 into the interior of the mounting plate 3. After the mounting plate 3 is fully inserted into the cavity 17 of the connecting plate 2, the limiting rod 9 will automatically lock into the through groove 10 at the top of the connecting plate 2 under the elastic force of the spring 7, forming a mechanical lock, thereby preventing the mounting plate 3 from accidentally coming out.

[0027] The present invention also includes that the top end of the mounting plate 3 is fixedly connected to the bottom end of the support column 4, the top end of the support column 4 is fixedly connected to the bottom end of the top plate 6, and threaded holes 5 are provided at the four corners of the top plate 6, the threaded holes 5 being used for screwing in the bolts 11.

[0028] In use, the top plate 6 is fixed to the bottom of the mobile device through the threaded holes 5 at its four corners. During operation, the bolts 11 are inserted from the bottom of the top plate 6 upwards into the threaded holes 5 and screwed into the preset mounting holes of the mobile device.

[0029] The present invention also includes positioning grooves 15 on both sides and the bottom surface of the mounting plate 3. The positioning grooves 15 are used for the positioning strips 18 to be installed and inserted. The positioning strips 18 are fixedly connected to the inner sides and the inner bottom surface of the connecting plate 2.

[0030] During use, the insertion process of the mounting plate 3 and the connecting plate 2 requires precise guidance through the positioning groove 15 and the positioning strip 18. The operator must strictly align the positioning strip 18 on the inner side of the connecting plate 2 with the positioning groove 15 on the corresponding side of the mounting plate 3 before inserting it, thereby increasing the connection friction between the mounting plate 3 and the connecting plate 2.

[0031] The present invention also includes two sliding grooves 14 on the opposite sides of the support column 4 and the opposite sides of the mounting plate 3. The two sliding grooves 14 are used for sliding installation of the sliders 16. One end of the two sliders 16 is fixedly connected to one side of the baffle 13.

[0032] In use, the baffle 13 is vertically slidable and adjustable through the cooperation of the slider 16 and the slide groove 14. After the connecting plate 2 and the mounting plate 3 are inserted, the baffle 13 is pushed down, and the sliders 16 on both sides move down along the slide groove 14 on the support column 4 and the mounting plate 3 until the baffle 13 can cover both sides of the connecting plate 2.

[0033] It should be noted that the slider 16 has a certain friction in the slide groove 14, so that the baffle 13 will not slide down naturally due to gravity after being pushed up. In addition, the slider 16 has a limiting structure in the slide groove 14, such as a T-shaped slider 16 and slide groove 14, which can prevent the slider 16 from being pulled out of the slide groove 14.

[0034] This utility model also includes that the bottom end of the bolt 11 contacts the top end of the connecting plate 2.

[0035] When in use, after the connecting plate 2 and the mounting plate 3 are connected together, the bottom end of the bolt 11 will abut against the top end of the connecting plate 2, thereby providing an anti-loosening function for the bolt 11.

[0036] The present invention also includes finger grooves 19 on both sides of the connecting plate 2, and the finger grooves 19 are connected to the inside of the through groove 10.

[0037] When in use, you can insert your finger into the finger groove 19 and press down on the limiting rod 9 so that the limiting rod 9 is pressed into the interior of the mounting plate 3, which will push the connecting plate 2 to separate the connecting plate 2 from the mounting plate 3.

[0038] In use, the top plate 6 is first attached to the bottom surface of the mobile device, and the bolts 11 are screwed into the threaded holes 5 from bottom to top until they are screwed into the bottom of the mobile device, so that the top plate 6 is fixedly connected to the mobile device. Then, the connecting plate 2 is placed on the outside of the mounting plate 3, and the positioning strips 18 on the inside of each connecting plate 2 are aligned with the positioning grooves 15 on the outside of the mounting plate 3. At the same time, the limiting rod 9 is pressed into the inside of the mounting plate 3 with a finger to compress the spring 7. Then, the mounting plate 3 is inserted into the inside of the connecting plate 2 by sliding the connecting plate 2 until the limiting rod 9 is pushed out into the through groove 10 by the spring 7. In this way, the limiting rod 9 provides a limiting effect for the connecting plate 2 from the inside of the connecting plate 2. Finally, by pushing the baffle 13 downward, the slider 16 slides in the slide groove 14, so that the baffle 13 blocks part of the sides of the connecting plate 2, further restricting the sliding of the connecting plate 2 and enhancing the connection stability of the connecting plate 2. At this time, the caster 1 is installed.

[0039] When it is necessary to disassemble caster 1, first push baffle 13 upward so that baffle 13 will not block the sliding of connecting plate 2. Then insert your finger into finger groove 19 and press down limit rod 9 so that limit rod 9 is pressed into the interior of mounting plate 3. Then push connecting plate 2 to separate connecting plate 2 from mounting plate 3.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
