Most existing bearing seats are integral bearing seats, and the bearings are installed by interference fit. The maintenance and replacement of the bearings are time-consuming and labor-intensive. Some bearing seats are upper split structures, but the upper and lower seats are fixed together by bolts. During later maintenance, specific tools and external forces are required to operate, affecting work efficiency. Utility Model Content

When maintenance is needed, the screw driving mechanism drives the screw rod to separate from the second blind hole, and pulls the connecting rod outward to separate it from the first blind hole, so that the upper seat body can be removed. It does not require special tools and large external force operation, is convenient for maintenance and replacement, and is firmly and stably installed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings.

When the mounting block 102 enters the connecting groove 202, it pushes the connecting rod 3, driving the connecting rod 3 to move into the through hole 203, and causing the stopping mechanism 4 to undergo elastic deformation until the first blind hole 103 corresponds to the through hole 203. The force pushing the connecting rod 3 disappears, and the reverse force of the stopping mechanism 4 causes one end of the connecting rod 3 to move into the first blind hole 103, and the stopping mechanism 4 always applies a pushing force, so that the connecting rod 3 is firmly in contact with the first blind hole 103, so that a lock is formed between the mounting block 102 and the connecting groove 202.

[0024] The stopping mechanism 4 includes a guide cylinder 401, a guide block 402, a spring 403, and a limit plate 404. The guide cylinder 401 is arranged on the lower connecting portion 201. One end of the connecting rod 3 passes through the through hole 203 and the guide cylinder 401, and extends to the outside of the guide cylinder 401. The guide block 402 is arranged on the connecting rod 3 inside the guide cylinder 401, and the guide block 402 is slidably connected to the inner wall of the guide cylinder 401. The spring 403 is sleeved on the connecting rod 3, and one end conflicts with the guide block 402, and the other end conflicts with the inner wall of the guide cylinder 401. The limit plate 404 is arranged on the connecting rod 3 outside the guide cylinder 401. After the mounting block 102 contacts the connecting rod 3, the connecting rod 3 and the guide block 402 are driven along the guide cylinder 401 to the through hole. The guide block 402 and the connecting rod 3 are moved toward the first blind hole 103 to form a locking mechanism, and the outer diameter of the limit plate 4 is larger than the inner diameter of the guide cylinder 401. When it is necessary to separate the mounting block 102 from the connecting groove 202, the limit plate 404 is pulled outward to separate the connecting rod 3 from the first blind hole 103, so that the mounting block 102 can be separated from the connecting groove 202 without the need for special tools and large external force. This makes the installation and disassembly between the upper base 1 and the lower base 2 more convenient, and makes its maintenance simpler and more convenient.

[0025] A first driving inclined surface 104 is provided at the bottom of both ends of the mounting block 102, and a second driving inclined surface 301 matching the first driving inclined surface 104 is provided at the end of the connecting rod 3 close to the mounting block 102. The first driving inclined surface 104 cooperates with the second driving inclined surface to facilitate the mounting block 102 to generate a driving force on the connecting rod 3.

[0026] A second blind hole 302 is provided on one side of the connecting rod 3, a screw rod 5 is provided on the outside of the lower connecting part 201, and a screw driving mechanism 6 connected to the screw rod 5 is provided, one end of the screw rod 5 passes through the lower connecting part 201 and the mounting block 102, and is threadedly connected to the second blind hole 302, a first connecting hole 105 connected to the second blind hole 301 is provided on the outside of the mounting block 102, and a second connecting hole 204 connected to the first connecting hole 105 is provided on the outside of the lower connecting part 201. The first connecting hole 105, the second connecting hole 204, and the second blind hole 302 are on the same central axis, one end of the screw rod 5 passes through the first connecting hole 105 and the second connecting hole 204, and is connected to the second blind hole 302. When the connecting rod 3 enters the first blind hole 10 3, the first connecting hole 105, the second connecting hole 204, and the second blind hole 302 are connected to each other, and the screw rod 5 is driven by the screw driving mechanism 6 to move horizontally, and the screw rod 5 enters the first connecting hole 105 and the second connecting hole 204, and is threadedly connected with the second blind hole 302, thereby limiting the axial movement of the connecting rod 3 so that it will not be separated from the first blind hole 103 due to external force, and then the upper base 1 and the lower base 2 are firmly installed together. When maintenance is needed, the screw rod 5 is driven by the screw driving mechanism 6 to separate from the second blind hole 302, and the connecting rod 3 is pulled outward to separate it from the first blind hole 103, so that the upper base 1 can be removed. It does not require special tools and large external force to operate, is convenient for maintenance and replacement, and is firmly and stably installed.

[0027] The screw drive mechanism 6 includes an annular slide rail 601 on the same central axis as the second connecting hole 204, and a knob 602 rotatably connected to the annular slide rail 601. The other end of the screw 5 passes through the annular slide rail 601 and is threadedly connected to the knob 602. The knob 602 is provided with an annular slide groove that matches the annular slide rail 601, so that the knob 602 can rotate stably on the annular slide rail 601, thereby driving the screw 5 to move back and forth horizontally.

[0028] A base 7 is provided at the bottom end of the lower seat body 2 , and a mounting hole is provided on the upper surface of the base 7 for fixing the base 7 on the equipment.

[0029] Example 2

[0030] The difference between this embodiment and the first embodiment is that a height adjustment frame is provided at the rear end of the upper body 1 and the lower body 2. The height adjustment frame includes a base 801, columns 802 symmetrically arranged on both sides of the upper surface of the base 801, and a beam 803 arranged at the top of the two columns 802. The base 801 is fixed to the equipment table by bolts. An adjusting screw 901 is rotatably provided on one side between the beam 803 and the base 801, and a sliding rod 902 is provided on the other side. A rotating block 903 connected to the adjusting screw 901 is provided on the top of the beam 803. The two ends of the rear end surface of the lower body 2 are fixed to the equipment table by bolts. Two driving members 10 are symmetrically arranged on the side, which are threadedly connected to the adjusting screw 901 and slidingly connected to the sliding rod 902. A sliding block 11 is provided on the side of the two driving members 10 close to the column 802, and the sliding block 11 cooperates with the sliding rod 902 to make the driving member 10 move back and forth stably up and down. By rotating the rotating block 903, the driving member 10 is driven to move back and forth up and down along the adjusting screw 901 to adjust the height of the lower seat 2 and the upper seat 1. The height position can be adjusted according to needs without repeated adjustment through gaskets, making it more practical.

[0031] On the column 802, a plurality of fastening holes 804 are evenly arranged from top to bottom, and a waist-shaped hole 701 matching the fastening hole 804 is opened on the base 7. The waist-shaped hole 701 generates a clamping force between the base 7 and the column 802 through bolts and nuts, making the lower seat 2 and the upper seat 1 more firm and stable on the height adjustment frame, and not easy to shake due to the force during transmission.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
