Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer housing. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine. It plays a crucial role in the field of mechanical transmission, and its main function is to reduce speed and increase torque to meet the power and motion parameter requirements of different working machines. In the application fields of speed reducers, the speed reducer housing is a key component that protects the internal mechanical structure and ensures the normal operation of the speed reducer, so its design and manufacturing quality are of paramount importance.

[0003] The existing utility model patent with publication application number CN213628818U discloses a speed reducer housing. A heat sink is installed inside the speed reducer, transferring heat from the inside of the housing to the heat sink. The heat sink then transfers heat from a water pipe to the water, which is circulated by a water pump. Water has a high specific heat capacity, absorbing heat inside the water pipe and releasing it in the water tank, thus cooling the speed reducer. However, the speed reducer housing consists of an upper and lower shell, fixed together by bolts. This method requires tools for installation and disassembly using ordinary bolts, making the operation relatively cumbersome, especially in situations with limited space or requiring frequent disassembly and maintenance. This cumbersome operation significantly reduces work efficiency and increases maintenance and time costs. Therefore, a speed reducer housing is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a speed reducer housing to address the aforementioned technical problems.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problems mentioned in the background art through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A speed reducer housing, comprising:

[0008] The bottom shell has an upper shell on its top. Several connecting holes are opened at the joints on both sides of the bottom shell and the upper shell. A fixing cylinder is provided in the inner cavity of the connecting holes.

A push column is fixedly connected to the bottom end of the screw. A groove is provided at the bottom of the connecting hole on the surface of the bottom shell. A protective component is provided at the top of the connecting hole on the surface of the upper shell.

[0010] In a preferred embodiment of the reducer housing provided by this utility model, a plurality of connecting holes on both sides of the top of the upper housing are arranged in a vertically corresponding manner to a plurality of connecting holes on both sides of the bottom of the upper housing.

[0011] In a preferred embodiment of the reducer housing provided by this utility model, there are several fixed cylinders, and the several fixed cylinders are respectively fixedly inserted into several connecting holes on the surface of the upper shell, and the bottom end of the fixed cylinder is movably inserted to the bottom of the corresponding connecting hole on the surface of the bottom shell.

[0012] In a preferred embodiment of the reducer housing provided by this utility model, the rotating block is square in shape, and the height of the inner cavity of the side hole is sufficient for the rotating block to rotate.

[0013] In a preferred embodiment of the reducer housing provided by this utility model, magnetic blocks are installed on opposite sides of the two rotating blocks, and the two magnetic blocks can be magnetically attracted to each other.

[0014] In a preferred embodiment of the reducer housing provided by this utility model, the top of the screw extends through to the top of the fixed cylinder and is fixedly connected to a knob.

[0015] In a preferred embodiment of the reducer housing provided by this utility model, the bottom end of the fixed cylinder extends into the inner cavity of the corresponding groove, and after the rotating block rotates, one side of its side fits against the top of the inner cavity of the groove.

[0016] In a preferred embodiment of the reducer housing provided by this utility model, the protective component includes a second groove formed at the top of the connecting hole on the surface of the upper housing, and the top of the fixing cylinder is fixedly inserted through the top of the second groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a reducer housing. During installation, the fixing cylinder is inserted into the corresponding connection hole, and the knob is turned. This causes the screw and push column to rotate and move downwards, pushing the two rotating blocks to rotate outwards by 90 degrees.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A reducer housing includes: a bottom shell 1, an upper shell 2 on the top of the bottom shell 1, several connecting holes 3 on both sides of the bottom shell 1 and the upper shell 2, and a fixed cylinder 4 inside the connecting hole 3; side holes 5 on both sides of the bottom of the fixed cylinder 4, a rotating block 6 rotatably connected to the top of the inner cavity of the side hole 5 via a rotating shaft, a screw 8 threadedly connected to the inner cavity of the fixed cylinder 4, and a push post 9 fixedly connected to the bottom end of the screw 8. The diameter of the push post 9 is smaller than that of the screw 8. The smaller diameter of the push post 9 allows it to concentrate the force transmitted from the screw 8 onto the rotating block 6 when it contacts the rotating block 6. This concentrated force can more effectively push the rotating block 6 to overcome friction and other resistance, and achieve stable rotation. A groove 11 is provided at the bottom of the connecting hole 3 on the surface of the bottom shell 1, and a protective member 12 is provided at the top of the connecting hole 3 on the surface of the upper shell 2.

[0033] In the embodiments of this application, several connecting holes 3 on both sides of the top of the upper shell 2 are arranged vertically corresponding to several connecting holes 3 on both sides of the bottom of the upper shell 2. Several fixing cylinders 4 are present, and each fixing cylinder 4 is fixedly inserted into the cavity of one of the connecting holes 3 on the surface of the upper shell 2. The bottom end of the fixing cylinder 4 extends movably to the bottom of the cavity corresponding to the connecting hole 3 on the surface of the bottom shell 1. The rotating block 6 is square in shape, and the height of the cavity of the side hole 5 allows the rotating block 6 to rotate. Magnetic blocks 7 are installed on opposite sides of the two rotating blocks 6, and the two magnetic blocks 7 can magnetically attract each other. Before installation or during disassembly, the magnetic blocks 7... The magnetic attraction allows the rotating block 6 to be held in a specific position. For example, when the two rotating blocks 6 are attracted by the magnetic block 7 before installation, the rotating block 6 is in the inner cavity of the fixed cylinder 4, which facilitates the docking operation of the fixed cylinder 4. The top of the screw 8 extends through to the top of the fixed cylinder 4 and is fixedly connected to the knob 10. The bottom end of the fixed cylinder 4 extends into the inner cavity of the corresponding groove 11. After the rotating block 6 rotates, one side of it fits against the top of the inner cavity of the groove 11. The groove 11 provides space for the rotating block 6 to fit, ensuring that the rotating block 6 can be stably fixed on the bottom shell 1, thereby ensuring the stability of the connection between the bottom shell 1 and the upper shell 2.

[0034] In the embodiments of this application, the protective component 12 includes a second groove 121 formed at the top of the connecting hole 3 on the surface of the upper shell 2. The top of the fixing cylinder 4 is fixedly inserted through the groove 121. A protective cover 122 is threadedly connected to the inner cavity of the groove 121. The protective cover 122 can provide good protection for the connecting hole 3 and the fixing cylinder 4, preventing external dust, moisture and other impurities from entering the connection part, avoiding problems such as wear and corrosion of the connection parts caused by impurities, and extending the service life of the reducer housing. A sealing ring 123 is installed at the bottom of the inner cavity of the groove 121. The bottom end of the protective cover 122 abuts against the sealing ring 123. The sealing ring 123 enhances the sealing between the protective cover 122 and the groove 121, further improving the protective effect and ensuring that the connection part is in a good sealing state.

[0035] The usage process of the reducer housing provided by this utility model is as follows: During installation, the upper housing 2 is first placed on top of the lower housing 1, so that the connecting holes 3 on both sides of the top of the upper housing 2 correspond vertically to the connecting holes 3 on both sides of the bottom of the upper housing 2. At this time, the two rotating blocks 6 are attracted to each other through the magnetic block 7, so that the rotating blocks 6 are in the inner cavity of the fixed cylinder 4 for easy docking. When the upper housing 2 and the lower housing 1 are docked, the fixed cylinder 4 is inserted into the corresponding connecting hole 3 until the bottom end of the fixed cylinder 4 moves through to the corresponding connecting hole 3 on the surface of the lower housing 1. The bottom of the inner cavity extends into the inner cavity of the groove 11. Then, the knob 10 is turned, which drives the screw 8 to rotate. The screw 8 moves downward, which in turn pushes the push column 9, which is fixedly connected to its bottom end, to move downward together. During the downward movement of the push column 9, it will contact the two rotating blocks 6 and apply force, pushing the two rotating blocks 6 to rotate outward by ninety degrees. After the rotating blocks 6 rotate, one side of the rotating blocks 6 rotates to the outside of the fixed cylinder 4 until it fits against the top of the inner cavity of the groove 11, thereby achieving a stable connection between the bottom shell 1 and the upper shell 2.
