Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a gear and rack lifting machine support mechanism. Background Technology

[0002] A rack and pinion jack is a mechanism that achieves lifting by the synchronous engagement of gears and a rack. Its working principle is that a motor drives the gears to rotate, which in turn drives the rack to move linearly up and down.

[0003] For example, announcement number CN214692811U, entitled "A Gear and Rack Lift Meshing Transmission Mechanism," includes a sleeve. A lifting rod is movably connected to the inner wall of the sleeve. Two symmetrically distributed grooves are formed on the outer wall of the lifting rod, and a rack is fixedly connected to the inner wall of each groove. Two symmetrically distributed rectangular through holes are formed on the outer wall of the sleeve, and fixed covers are fixedly connected to the walls of these through holes. Circular holes are formed on the front and rear outer walls of both fixed covers. This double-sided meshing ensures the force balance of the gear and rack lift meshing transmission mechanism, improving the reliability of the transmission, reducing wear, and extending its service life. Furthermore, the limiting mechanism provides a self-locking function, enhancing the safety and reliability of the gear and rack lift.

[0004] Although the existing rack and pinion lift has a self-locking support structure, this structure has the following drawbacks: 1. The structure is complex to install and inconvenient for users to disassemble and replace later; 2. The self-locking head is a single-head structure, and the locking support effect is poor. Therefore, it does not meet the current needs. In response, a rack and pinion lift support mechanism is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a support mechanism for a rack and pinion lift, so as to solve the problems mentioned in the background art, such as the poor locking support effect of the existing rack and pinion lift self-locking support mechanism and the complex overall structure that is inconvenient for users to replace.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear and rack lifting mechanism, comprising: a housing, a gear rotating component, a rack lifting component, a limiting component, and a self-locking reinforcing support component. The gear rotating component is installed at the center of the housing. A rack lifting component meshing with and transmitting power to the gear rotating component is installed on one side of the gear rotating component. A limiting component is installed on the side of the rack lifting component away from the gear rotating component. A self-locking reinforcing support component is installed on the other side of the gear rotating component. The self-locking reinforcing support component includes a vertical self-locking strip. Several vertically spaced locking teeth are provided on the outer wall of the self-locking strip near the gear rotating component. An electric telescopic rod is installed at the other end of the self-locking strip.

[0007] Preferably, guide frames are installed at both the upper and lower ends of the self-locking clip, and guide grooves are provided inside the guide frames. Guide blocks are installed inside the guide grooves, and the guide blocks are connected to the ends of the self-locking clip by bolts.

[0008] Preferably, the gear rotating component includes a gear, and a servo motor is mounted on one end of the gear.

[0009] Preferably, the rack lifting component includes a rack frame, and an outer edge support frame extending to the outside of the housing is provided above the rack frame. Limiting sliders are provided on both sides of the outer edge support frame and the rack frame.

[0010] Preferably, the limiting component includes a limiting frame, the limiting frame having a rack assembly groove inside, and the rack frame located within the rack assembly groove.

[0011] Preferably, the rack assembly groove has limit grooves on both sides, and the limit slider moves up and down within the limit grooves.

[0012] Preferably, a cover plate is installed on the top of the housing, and an opening is provided on the outer wall of the cover plate for the rack and pinion lifting component to move up and down.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the self-locking clip is moved back and forth by the electric telescopic rod. When moving forward, the locking teeth of the self-locking clip are inserted into the tooth groove of the gear, so that both sides of the gear are restricted by the self-locking clip and the rack frame respectively, thereby improving the self-locking reinforcement support of the rack frame. In this self-locking reinforcement support structure, the locking teeth are arranged vertically at intervals, so that when self-locking is restricted, multiple gear tooth grooves can be restricted at one time, thereby effectively improving the self-locking support effect. When subsequent adjustment is required, it is only necessary to drive the self-locking clip to retract backward by the electric telescopic rod to separate the locking teeth from the gear tooth groove, thereby realizing a quick and flexible self-locking support operation. In addition, the self-locking support structure is simple and easier to replace later, solving the problem that the existing gear rack lift self-locking support mechanism has poor locking support effect and complex overall structure that is inconvenient for users to replace.

[0015] (2) In this utility model, the limiting frame and the rack assembly groove are used to limit the position of the rack frame, ensure that the rack frame can mesh with the gear, and prevent the rack frame from deviating. During the lifting and lowering movement of the rack frame, the limiting sliders on both sides will slide in the limiting groove. The sliding improves the smoothness and stability of the displacement process. Furthermore, the limiting sliders can further limit the lifting and lowering process of the rack frame, prevent its lifting and lowering deviation, and improve stability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1 , Figure 4 This utility model provides an embodiment of a gear and rack lifting mechanism, comprising: a housing 1, a gear rotating component 2, a rack lifting component 3, a limiting component 4, and a self-locking reinforcing support component 5. The gear rotating component 2 is installed at the center of the housing 1. The rack lifting component 3, which meshes with the gear rotating component 2, is installed on one side of the gear rotating component 2. The limiting component 4 is installed on the side of the rack lifting component 3 away from the gear rotating component 2. The self-locking reinforcing support component 5 is installed on the other side of the gear rotating component 2. The self-locking reinforcing support component 5 includes a vertical self-locking bar 502. Several vertically spaced locking teeth 503 are provided on the outer wall of the self-locking bar 502 near the gear rotating component 2. An electric telescopic rod 501 is installed at the other end of the self-locking bar 502.

[0023] The electric telescopic rod 501 drives the self-locking clip 502 to move back and forth. When moving forward, the locking teeth 503 at the self-locking clip 502 are inserted into the tooth groove of the gear 201, so that both sides of the gear 201 are restricted by the self-locking clip 502 and the rack frame 301 respectively, thereby improving the self-locking reinforcement support of the rack frame 301. In this self-locking reinforcement support structure, if the locking teeth 503 are arranged vertically at intervals, multiple tooth grooves of the gear 201 can be restricted at one time when self-locking is restricted, thereby effectively improving the self-locking support effect. When subsequent adjustment is required, it is only necessary to drive the self-locking clip 502 to retract backward by the electric telescopic rod 501, so that the locking teeth 503 are separated from the tooth groove of the gear 201, realizing a quick and flexible self-locking support operation.

[0024] Furthermore, such as Figure 4 As shown, guide frames 504 are installed at both the upper and lower ends of the self-locking clip 502. The guide frame 504 has a guide groove 505 inside, and a guide block 506 is installed inside the guide groove 505. The guide block 506 is connected to the end of the self-locking clip 502 by bolts. When the electric telescopic rod 501 pushes the self-locking clip 502 to move, the two ends of the self-locking clip 502 can slide within the guide groove 505 through the guide block 506, making the displacement process smoother.

[0025] Please see Figure 1 , Figure 2 The top of the housing 1 is equipped with a cover plate 101. The outer wall of the cover plate 101 has an opening 102 for the rack lifting component 3 to move up and down. The gear rotating component 2 includes a gear 201. A servo motor 202 is installed at one end of the gear 201. The rack lifting component 3 includes a rack frame 301. An outer edge support frame 302 extending to the outside of the housing 1 is provided above the rack frame 301. Limit sliders 303 are provided on both sides of the outer edge support frame 302 and the rack frame 301.

[0026] The servo motor 202 is used to drive the gear 201 to rotate. The tooth groove of the gear 201 meshes with the protruding tooth block of the rack frame 301. When the gear 201 is rotating, it drives the rack frame 301 to move upward, so that the rack frame 301 and the outer edge support frame 302 move out of the opening 102 to the outside of the housing 1, which achieves the effect of rising. When descending, the servo motor 202 only needs to reverse the gear 201 to drive the rack frame 301 to move downward.

[0027] Please see Figure 1 , Figure 3The limiting component 4 includes a limiting frame 401, with a rack assembly groove 402 inside the limiting frame 401. The rack frame 301 is located inside the rack assembly groove 402. Limiting grooves 403 are provided on both sides inside the rack assembly groove 402. The limiting sliders 303 slide up and down within the limiting grooves 403. The limiting frame 401 and the rack assembly groove 402 are used to limit the position of the rack frame 301, ensuring that the rack frame 301 can mesh with the gear 201 and preventing the rack frame 301 from deviating. During the lifting and lowering movement of the rack frame 301, the limiting sliders 303 on both sides slide within the limiting grooves 403. The sliding improves the smoothness and stability of the displacement process. Furthermore, the limiting sliders 303 can further limit the lifting and lowering process of the rack frame 301, preventing it from deviating during lifting and lowering and improving stability.
