Description

Technical Field

[0001] The utility model belongs to the technical field of racks, and in particular relates to a highly wear-resistant guide rail rack. Background Art

[0002] A rack is a special gear with teeth distributed on a bar-shaped body. Racks are also divided into spur racks and helical racks, which are used in pairs with spur cylindrical gears and helical cylindrical gears respectively. The rack can cooperate with the gear to achieve a guiding effect, thereby realizing linear movement. After searching, it was found that the application number "202122706012.4" discloses "a rust-proof rack", which records "including a rack body, a splicing assembly and a lubrication assembly, the outer side of the rack body is provided with a protective assembly for rust prevention, the splicing assembly for splicing is arranged at the left and right ends of the rack body, and the lubrication assembly for lubrication is arranged inside the rack body, the rack body includes a tooth seat plate, convex teeth and pin holes, the top surface of the tooth seat plate is provided with convex teeth, and the inside of the tooth seat plate is provided with pin holes". When the above-mentioned rack is used, The splicing assembly allows multiple racks to be spliced ​​together, thereby extending the service length of the racks. The above-mentioned splicing method is plug-in, which is simple and quick, and can improve the splicing efficiency of the racks. In addition, the surface of the rack body is provided with a wear-resistant layer, which can effectively improve the wear resistance of the racks. However, the above-mentioned racks still have certain shortcomings when in use: when the above-mentioned racks are spliced ​​together, one end of a rack needs to be inserted into the other end of another rack. When multiple racks are spliced ​​together, if the rack in the middle is severely worn and needs to be replaced, since one end of the rack is inserted into another rack and the other end of the rack has one end of another rack plugged into it, when the rack needs to be disassembled, the adjacent rack needs to be disassembled before it can be removed, which makes it inconvenient to disassemble and replace the rack.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 6 The utility model provides the following technical solutions: a highly wear-resistant guide rail rack, comprising a rack body 1, the rack body 1 comprising a tooth seat plate 11 and a convex tooth 12 arranged on the top of the tooth seat plate 11, recesses 2 are staggered at both ends of the tooth seat plate 11, the bottom end of the recess 2 at one end is fixedly connected to a fixing component 3, and a mounting groove 4 is opened on the surface of the recess 2 at the other end, and fixing holes 5 are opened on both sides of the mounting groove 4, and unlocking components 6 are installed on both sides of the recess 2 located at the mounting groove 4.

[0021] In this embodiment, a wear-resistant layer 7 is provided on the surface of the rack body 1. The wear-resistant layer 7 is made of carburizing technology, and the rack body 1 is made of low-carbon steel.

[0022] Specifically, the wear resistance of the rack body 1 can be significantly improved by providing the wear-resistant layer 7 , and the rack body 1 is made of low-carbon steel, which can improve the toughness of the rack body 1 .

[0023] In this embodiment, the fixing assembly 3 includes a fixing block 31 fixedly installed at the bottom end of the corresponding recessed platform 2, a first installation cavity 32 is opened inside the fixing block 31, openings penetrating the first installation cavity 32 are opened on both sides of the fixing block 31, two limit plates 33 are slidably installed in the first installation cavity 32, a telescopic rod 34 is fixedly connected between the two limit plates 33, a first spring 35 is sleeved on the outside of the telescopic rod 34, both ends of the first spring 35 are respectively connected to the surfaces of the two limit plates 33, a positioning block 36 is fixedly connected to one side of the two limit plates 33, and one end of the positioning block 36 extends to the outside through the opening.

[0024] Specifically, after the fixing block 31 is installed in the installation groove 4, the limiting plate 33 drives the positioning block 36 to be inserted into the fixing hole 5 under the action of the first spring 35, so that the two rack bodies 1 can be quickly spliced ​​together in this way.

[0025] In this embodiment, the unlocking component 6 includes a second installation cavity 61 opened inside the two sides of the corresponding recessed platform 2, the two sides of the second installation cavity 61 are connected, a guide rod 62 is arranged in the second installation cavity 61, a limit ring 63 is installed on the surface of the guide rod 62 located in the second installation cavity 61, the limit ring 63 is slidably installed in the second installation cavity 61, one end of the guide rod 62 located on the outside is fixedly connected to a push block 64, and a second spring 65 is sleeved on the outside of the guide rod 62, and the two ends of the second spring 65 are respectively connected to the recessed platform 2 and the push block 64.

[0026] Specifically, when multiple rack bodies 1 need to be removed for replacement after being spliced, the staff only needs to push the push blocks 64 on both sides inward, and the push blocks 64 will drive the guide rod 62 to squeeze the positioning block 36 inward. The limiting ring 63 slides in the second mounting cavity 61 to guide the movement of the guide rod 62, and the positioning block 36 is pushed inward to drive the limiting plate 33 to squeeze the first spring 35. When the positioning block 36 is out of the fixing hole 5, the rack body 1 can be lifted upward to complete the disassembly of the corresponding rack body 1. This disassembly method is simple and convenient, and effectively improves the work efficiency of the staff.

[0027] In this embodiment, first wedge-shaped surfaces 8 are formed on both sides of the top of the concave platform 2 located at the installation groove 4 , and a second wedge-shaped surface 9 is formed at the bottom of the end of the positioning block 36 .

[0028] Specifically, when multiple rack bodies 1 are spliced, when the fixing block 31 is installed in the mounting groove 4, the first wedge surface 8 is set to cooperate with the second wedge surface 9 opened at the end of the positioning block 36 so that when the staff installs the rack body 1 downward, the positioning block 36 will be squeezed inwardly under the action of the first wedge surface 8 and the second wedge surface 9, and when the positioning block 36 moves to the fixing hole 5, the positioning block 36 will be inserted into the fixing hole 5 under the action of the first spring 35, thereby facilitating and quickly splicing the rack body 1.

[0029] In this embodiment, when the fixing block 31 is installed in the installation groove 4 and the positioning block 36 is installed in the fixing hole 5 , one end of the guide rod 62 is in close contact with the positioning block 36 .

[0030] Specifically, when the rack body 1 needs to be disassembled, it is only necessary to push the guide rod 62 so that the guide rod 62 drives the positioning block 36 to be separated from the fixing hole 5 . This method can improve the disassembly efficiency of the rack body 1 .

[0031] Working principle: When multiple rack bodies 1 are spliced, it is only necessary to insert the fixing component 3 at the bottom of one end of a rack body 1 into the mounting groove 4 of another rack body 1. With the cooperation of the fixing component 3, the mounting groove 4 and the fixing hole 5, the splicing of multiple rack bodies 1 can be completed quickly and conveniently. This splicing method is simple and convenient, and can effectively improve the splicing efficiency of the rack bodies 1. When one of the rack bodies 1 is severely worn and needs to be replaced, it is only necessary to disengage the positioning block 36 from the fixing hole 5 with the cooperation of the unlocking component 6, and then remove the rack body 1 upward to quickly complete the disassembly. This disassembly method does not require the removal of the rack bodies 1 on both sides, and then replace the new rack body 1 in the above manner. This disassembly and assembly method can effectively improve the work efficiency of the staff.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
