Description

Technical Field

[0001] The utility model relates to the technical field of reduction gearboxes, and in particular to a reduction gearbox connecting bracket with a multi-point fixing effect. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. Reducers are generally used for low-speed and high-torque transmission equipment. The power of an electric motor, internal combustion engine or other high-speed operation is decelerated by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

[0003] The patent specification with announcement number CN202708015U discloses a kind of longitudinal shear unit reduction box bracket, which includes a base, a support column extending from the base in the vertical direction, a connecting arm connected to the reduction box main body is arranged on one side of the support column, the connecting arm includes a first connecting arm and a second connecting arm extending obliquely upward, the first connecting arm and the second connecting arm are arranged up and down respectively, an auxiliary supporting column is arranged on the side opposite to the side of the support column where the connecting arm is arranged, and the auxiliary supporting column, the support column and the base together form a triangle. Compared with the prior art, the bracket of the utility model is arranged in a structure of multiple connecting arms and auxiliary supporting columns, which ensures the perfect fixation of the reduction box and has high production safety performance.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for the relatively convenient disassembly and assembly of the reducer during use, and the staff are required to perform relatively tedious installation work, which requires a lot of time and manpower costs in preparation work. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a reduction gearbox connecting bracket with a multi-point fixing effect, which solves the problem in the related art that it is inconvenient to conveniently disassemble and assemble the reduction gearbox.

[0006] The technical solution of the utility model is as follows:

[0007] A reduction box connecting bracket with a multi-point fixing effect comprises a reduction box body, two groups of sliding shells and two groups of fixed shells are respectively provided on both sides of the outside of the reduction box body, rod bodies are provided inside the sliding shells and the fixed shells, multiple groups of rod bodies are fixedly connected to the outer surfaces of the sliding shells and the fixed shells, the rod bodies are symmetrically distributed left and right with the sliding shells and the fixed shells as the center, one end of the rod bodies on the same side away from the inner side is fixedly connected with a mounting plate, connecting rods are fixedly connected between the two groups of sliding shells and the two groups of fixed shells, two threaded rods are threadedly connected inside the sliding shells, a rotating plate is fixedly connected to the outer ends of the threaded rods, a plurality of anti-skid plates are fixedly connected to the outside of the rotating plate, and an adapter plate is fixedly connected to one end of the threaded rods.

[0008] Preferably, the rod body is slidably connected to the sliding shell, and the fixed shell is fixedly connected to the rod body.

[0009] Preferably, one side of the exterior of one of the sliding shell and the fixed shell is fixedly connected with a folding rod, and one end of the two folding rods is fixedly connected with a support plate.

[0010] Preferably, the interiors of the two support plates are in contact with the exterior of the reducer body, and the interiors of the sliding shell and the fixed shell are in contact with the exterior of the reducer body.

[0011] Preferably, two through slots are provided inside the fixing shell, and the shape of the adapter plate is the same as the shape of the inside of the through slots.

[0012] Preferably, a first clamping plate is fixedly connected to both sides of the exterior of the sliding shell, and a second clamping plate is fixedly connected to both sides of the exterior of the fixed shell.

[0013] Preferably, a spring is fixedly connected to one side of the second clamping plate, and the spring is in contact with one side of the first clamping plate.

[0014] Preferably, the spring is in an undeformed state, and a plurality of anti-slip plates are distributed in a circular shape.

[0015] The working principle and beneficial effects of the utility model are:

[0016] In the utility model, when the adapter plate passes through the through slot inside the fixed shell in a vertical state, the staff can reverse the rotating plate and the anti-slip plate at this time. The rotating plate will synchronously drive the threaded rod and the adapter plate to reverse during the rotation process, and then the threaded rod will be screwed out in the direction of the rotating plate. At this time, the adapter plate will tighten one side of the fixed shell, so that the rotating plate can reduce the distance between the sliding shell and the fixed shell during the reversal process, ensuring firmness and solving the problem of inconvenient disassembly and assembly of the reducer.

[0017] When the reducer body needs to be disassembled, the staff needs to rotate the adapter plate to a state that is compatible with the internal through groove of the fixed shell. At this time, the spring will drive the clamping plate to move outward through its own elastic force. During the movement, the clamping plate will simultaneously drive the sliding shell to slide on the outside of the rod body, thereby facilitating the separation of the sliding shell and the fixed shell, ensuring the use effect and solving the problem of inconvenient disassembly and assembly of the reducer.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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. Example 1

[0025] like Figure 1~Figure 3As shown, the present embodiment proposes a reduction box connecting bracket with a multi-point fixing effect, comprising a reduction box body 1, two groups of sliding shells 2 and two groups of fixed shells 8 are respectively provided on both sides of the outside of the reduction box body 1, rod bodies 3 are provided inside the sliding shells 2 and the fixed shells 8, and multiple groups of rod bodies 3 are fixedly connected to the outer surfaces of the sliding shells 2 and the fixed shells 8, and the rod bodies 3 are respectively symmetrically distributed with the sliding shells 2 and the fixed shells 8 as the center, and a mounting plate 4 is fixedly connected to one end of the rod bodies 3 on the same side away from the inner side, and connecting rods 5 are fixedly connected between the two groups of sliding shells 2 and the two groups of fixed shells 8, and two threaded rods 10 are connected inside the sliding shell 2 by threads, and a rotating plate 9 is fixedly connected to the outer end of the threaded rod 10, and a plurality of anti-skid plates 15 are fixedly connected to the outside of the rotating plate 9, and an adapter plate 11 is fixedly connected to one end of the threaded rod 10.

[0026] In this embodiment, the rod body 3 is slidably connected to the sliding shell 2, and the fixed shell 8 is fixedly connected to the rod body 3, which can facilitate the connection work between the sliding shell 2 and the fixed shell 8.

[0027] In this embodiment, one side of the sliding shell 2 and the fixed shell 8 is fixedly connected to a folding rod 6 , and one end of the two folding rods 6 is fixedly connected to a support plate 7 , which can facilitate the connection work of the support plate 7 .

[0028] In this embodiment, the interiors of the two support plates 7 are in contact with the exterior of the reducer body 1 , and the interiors of the sliding shell 2 and the fixed shell 8 are in contact with the exterior of the reducer body 1 , which can facilitate multi-point support of the reducer body 1 .

[0029] In this embodiment, two through slots are provided inside the fixing shell 8, and the shape of the adapter plate 11 is the same as the shape inside the through slots, so that the separation work can be facilitated.

[0030] During use, when the reducer body 1 needs to be installed and fixed, the staff first needs to install the mounting plates 4 on both sides at the corresponding points, and then the staff needs to place the reducer body 1 between the sliding shell 2 and the fixed shell 8, and then push the connecting rod 5 or the folding rod 6 on one side. The folding rod 6 will synchronously drive the supporting plate 7 to move during the pushing process, and the sliding shell 2 will slide on the outside of the rod body 3. The sliding shell 2 will synchronously drive the threaded rod 10, the rotating plate 9 and the anti-skid plate 15 to move during the movement, and the threaded rod 10 will drive the adapter plate 11 to move. When the adapter plate 11 passes through the through slot inside the fixed shell 8 in a vertical position, the staff can reverse the rotating plate 9 and the anti-slip plate 15. The rotating plate 9 will synchronously drive the threaded rod 10 and the adapter plate 11 to reverse during the rotation, and then the threaded rod 10 will be screwed out in the direction of the rotating plate 9. At this time, the adapter plate 11 will tighten one side of the fixed shell 8, so that the rotating plate 9 can reduce the distance between the sliding shell 2 and the fixed shell 8 during the reversal process to ensure firmness. At the same time, the support plates 7 on both sides will be in contact, so as to achieve multi-point support for the reducer body 1. Example 2

[0031] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that both sides of the outside of the sliding shell 2 are fixedly connected with a clamping plate 12, and both sides of the outside of the fixed shell 8 are fixedly connected with a clamping plate 2 13, which can facilitate the fixed connection of the clamping plate 12.

[0032] In this embodiment, a spring 14 is fixedly connected to one side of the second clamping plate 13 , and the spring 14 is in contact with one side of the first clamping plate 12 , which can facilitate the fixing and energy storage of the spring 14 .

[0033] In this embodiment, the spring 14 is in an undeformed state, and a plurality of anti-slip plates 15 are arranged in a circular distribution, which can facilitate the deformation of the spring 14 .

[0034] During use, during the process of connecting the sliding shell 2 with the fixed shell 8, the sliding shell 2 will drive the card plate 12 to move, and the card plate 12 will continue to be in close contact with the spring 14 during the movement. Although the spring 14 is elastic, it does not affect the spiral performance of the threaded rod 10 inside the sliding shell 2. Therefore, when it is necessary to disassemble the reducer body 1, the staff needs to rotate the adapter plate 11 to a state that is compatible with the internal through groove of the fixed shell 8. At this time, the spring 14 will drive the card plate 12 to move outward through its own elastic force, and the card plate 12 will synchronously drive the sliding shell 2 to slide on the outside of the rod body 3 during the movement, thereby facilitating the separation work between the sliding shell 2 and the fixed shell 8 and ensuring the use effect.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
