[0028] The following will be combined with the drawings in 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 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.

[0029] Reference Figure 1-3 The utility model provides an embodiment: an assembled bearing seat, including a lower shaft seat 1, an upper shaft cover 2 is slidably connected to the top of the lower shaft seat 1, and fixed blocks 3 are slidably connected to the left and right ends of the lower shaft seat 1, worms 6 are rotatably connected to the left and right ends of the interior of the lower shaft seat 1, and worm wheels 7 are rotatably connected to the left and right ends of the interior of the lower shaft seat 1, and the two worms 6 are respectively meshed with the two worm wheels 7, and the insides of the two worm wheels 7 are fixedly connected with threaded rods 8, and threaded holes are provided at the left and right ends of the upper shaft cover 2. The ends of the two threaded rods 8 away from the worm wheels 7 are respectively threadedly connected to the inside of the threaded holes, and a buckle assembly and a pulling assembly are provided inside the lower shaft seat 1, and the rear sides of the two worms 6 are fixedly connected to connecting rods 5, and the ends of the two connecting rods 5 away from the worm 6 are fixedly connected to the turning handle 4, and grooves 17 are provided inside the lower shaft seat 1 and the upper shaft cover 2.

[0030] Specifically, the lower shaft seat 1 is a part of the bearing seat, which is mainly used to support and position the shaft at the lower end. It ensures that the shaft can rotate stably and bear the load on the shaft. The upper shaft cover 2 is usually a part of the bearing seat, which is used to cover the bearing and the shaft to provide additional protection and support. The fixing block 3 is used to stabilize and fix other components. The bearing seat is usually installed on other structures through the fixing block 3. The handle 4 is used to rotate and adjust the handwheel of other components. The connecting rod 5 is an element connecting mechanical parts, which is used to transmit motion to the worm 6. The worm 6 and the worm wheel 7 cooperate with each other to convert and transmit motion to the threaded rod 8. The threaded rod 8 is used to thread the upper shaft cover 2 and the lower shaft seat 1. The groove 17 is used to accommodate the bearing or the shaft.

[0031] Reference Figure 1 and Figure 4 The buckle assembly includes a spring 14, which is fixedly connected to the interior of the lower shaft seat 1, a slider 11 is fixedly connected to the top of the spring 14, and an L-shaped block 10 is fixedly connected to the left side of the slider 11. The pulling assembly includes two connecting plates 13, which are rotatably connected to the left and right sides of the slider 11 respectively, and a pull rod 15 is rotatably connected between the ends of the two connecting plates 13 away from the slider 11. The left and right sides of the bottom of the slider 11 and the left and right sides of the pull rod 15 close to the spring 14 are fixedly connected with a rotating rod 12, and the ends of the two connecting plates 13 close to the slider 11 are respectively rotatably connected to the slider 11 through two of the rotating rods 12, and the ends of the two connecting plates 13 close to the pull rod 15 are respectively rotatably connected to the pull rod 15 through the other two rotating rods 12. A sliding groove 16 is opened in the interior of the lower shaft seat 1, and the slider 11 is slidably connected to the interior of the sliding groove 16. A card slot 9 is opened in the interior of the fixed block 3, and the L-shaped block 10 is slidably connected to the interior of the card slot 9.

[0032] Specifically, the slot 9 is a slot body with a special structure for accommodating the L-shaped block 10, so that it can move or be positioned relative to the slot 9. The L-shaped block 10 is used to limit the movement of the fixed block 3. The slider 11 is used to drive the L-shaped block 10 to move by transmitting power. The rotating rod 12 is used to connect the connecting plate 13, and the connecting plate 13 is used to connect the slider 11 and the pull rod 15. The spring 14 provides elastic support, the pull rod 15 provides pulling force, and the slide groove 16 is used to accommodate the sliding of the slider 11.

[0033] Working principle: Determine the working environment and working requirements, select a suitable fixed block 3 to install the bearing seat, pull the pull rod 15, and the pulling force passes through the connecting plate 13 to the slider 11, so that the slider 11 compresses the spring 14 to drive the L-shaped block 10 on the left to move, and then fit the fixed block 3 against the lower shaft seat 1, so that the L-shaped block 10 enters the inside of the slot 9, release the pull rod 15, the spring 14 resets, and the thrust pushes the slider 11, so that the L-shaped block 10 is embedded in the inside of the slot 9. After the installation of the fixed block 3 is completed, the bearing seat can be installed at the workplace.

[0034] After fixing the lower shaft seat 1, place the bearing or shaft into the lower shaft seat 1, then align the two threaded holes of the upper shaft cover 2 with the two threaded rods 8, and turn the two handles 4 at the same time to rotate the worm 6 through the connecting rod 5, so that the worm wheel 7 rotates with the rotation of the worm 6, and drives the internally fixed threaded rod 8 to rotate, and the upper shaft cover 2 and the lower shaft seat 1 can be installed and fixed. Because the meshing of the worm wheel 7 and the worm 6 has a self-locking feature, the vibration generated during the working process will not cause the upper shaft cover 2 and the lower shaft seat 1 to loosen.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
