[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment: A slide, such as Figure 1-Figure 5 As shown, it includes a base 1, a rack 2, a slider 3, a bearing seat 4, a gear shaft 5, a locking nut 6 and a first knob 7. The upper part of the base 1 is in the shape of a dovetail groove. A straight groove parallel to the square groove and equal in width is provided on the top of the base 1. The rack 2 is installed in the straight groove. A dovetail groove is provided at the bottom of the slider 3. The slider 3 is slidably connected to the base 1 through the dovetail groove. A square groove is provided on the slider 3 above the dovetail groove. The square groove fits with the rack 2. Two threaded holes are provided on the slider 3. A countersunk hole matching the threaded hole on the slider 3 is provided on the bearing seat 4. The slider 3 and the bearing seat 4 are fixedly connected by a hexagon socket bolt. Corresponding pin holes are provided on the bearing seat 4 and the slider 3. The slider 3 and the bearing seat 4 are installed and positioned by inserting pins into the pin holes. The right side of the slider 3 is fixedly connected to the bearing seat 4. The height of the highest point of the bearing seat 4 after installation is lower than or equal to the height of the upper side of the slider 3. The inner ring of the bearing on the bearing seat 4 is connected to the gear shaft 5, the gear at the shaft end of the gear shaft 5 is meshed with the rack 2, and the rear part of the gear shaft 5 is connected to a locking nut 6. The gear shaft 5 consists of a rotating shaft with three step surfaces and a gear connected to the rotating shaft with a key. The rotating shaft diameter on the front side of the front step surface is larger than the diameter of the inner ring of the bearing on the bearing seat 4, and the rotating shaft diameter between the front step surface and the middle step surface is smaller than the diameter of the inner ring of the bearing on the bearing seat 4. An external thread is provided on the rotating shaft on the rear side of the rearmost step surface, a through hole is provided in the middle of the locking nut 6, and an internal thread is provided in the through hole. The locking nut 6 is connected to the gear shaft 5 through a thread, and a first knob 7 is connected to the rear end of the gear shaft 5. By turning the first knob 7, the first knob 7 drives the gear shaft 5 and the locking nut 6 to rotate. Since the gear at the shaft end of the gear shaft 5 is meshed with the rack 2, the gear shaft 5 drives the slider 3 to slide through the bearing seat 4 to achieve displacement.

[0025] like Figure 4As shown, it also includes a baffle 8 and a second knob 10. The baffle 8 is fixedly connected to the upper part of the base 1. The baffle 8 is located on the front side of the rack 2 and is installed parallel to the rack 2. The highest point of the baffle 8 is lower than or equal to the height of the upper side of the rack 2. A limiting groove 9 is provided at the position where the slider 3 overlaps with the slider 3. The second knob 10 is connected to the slider 3 through a threaded hole. The second knob 10 overlaps with the baffle 8 in the front-to-back direction. The baffle 8 is used to insert into the limiting groove 9 to limit the slider 3.

[0026] The rack 2 is installed in the slot on the base 1 by bolt connection, and the slider 3 is assembled with the upper part of the base 1 and the rack 2 through the dovetail groove and the square groove. Then, the gear shaft 5 is moved to pass through the inner ring of the bearing on the bearing seat 4, and the locking nut 6 is installed to the rear of the gear shaft 5 and rotated to contact the inner ring of the bearing on the bearing seat 4. The first knob 7 is installed to the rear end of the gear shaft 5, and then the baffle 8 is installed on the base 1. In this way, the assembly of the slide is completed, which solves the problem that the slide is not easy to assemble at present. Subsequently, the gear shaft 5 and the locking nut 6 are driven to rotate by turning the knob. Through the meshing transmission of the gear shaft 5 and the rack 2, the gear shaft 5 drives the slider 3 to slide on the base 1 through the bearing seat 4 to achieve displacement. After completing the translational movement, the second knob 10 is inserted into the upper limit groove 9 of the slider 3 from the front to contact the baffle 8, thereby limiting the slider 3. When the slider 3 does not need to be limited, the second knob 10 can be pulled out and disengaged from the baffle 8.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
