Description

Technical Field

[0001] This utility model relates to the field of belt clamps, specifically a belt mounting structure for a belt-driven lifting platform. Background Technology

[0002] Belt-driven lifting platforms use a belt to drive a pulley system, which in turn drives the scissor arms to open and close, achieving lifting and lowering. They are relatively inexpensive, their components are easy to disassemble and maintain, and the motor is typically located on the outside of the lifting platform, resulting in smoother and more stable operation.

[0003] For example, patent CN220907034U discloses a novel belt lifting mechanism, which includes a frame, a placement assembly, a lifting adjustment assembly, and a drive assembly. The placement assembly is slidably connected to the frame. The lifting adjustment assembly has at least two sets, evenly distributed on both sides of the placement assembly. The lifting adjustment assembly includes a first transmission belt, a first transmission clamp, and two first transmission wheels, both of which are rotatably connected to the frame. The first transmission belt is driven by the two first transmission wheels, and the first transmission clamp is fixedly connected to the first transmission belt and the placement assembly respectively. The drive assembly includes a first rotary driver, a synchronizing rod, and two drive rods. The two drive rods are located on both sides of the placement assembly. One of the first transmission wheels in the lifting adjustment assembly is fixedly connected to the corresponding drive rod. The synchronizing rod is located between the two drive rods, and the synchronizing rod and the drive rod are driven by a corner actuator. The first rotary driver is used to drive any one of the drive rods to rotate.

[0004] The aforementioned patent uses a transmission clamp to connect the transmission belt and the placement component; however, the disadvantage of the aforementioned patent is that the transmission clamp in the prior art generally has poor stability in fixing the belt. For example, in the new energy vehicle refrigerator drawer and transmission belt fixing structure disclosed in the authorization announcement number CN222988041U, the clamping assembly disclosed in the aforementioned patent is horizontal with the transmission belt. After a period of use, it is easy for relative displacement to occur between the clamping assembly and the transmission belt, which leads to a decrease in transmission accuracy.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a belt-mounted lifting platform structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The belt-mounted lifting platform includes a fixed base; a belt mounting groove is provided at the front end of the fixed base, and a belt fixing block is movably disposed in the belt mounting groove; both the belt mounting groove and the belt fixing block have trapezoidal cross sections; the fixed base and the belt fixing block are also fixedly connected by belt fixing bolts; guide grooves are provided on the left and right side walls of the inner cavity of the belt mounting groove; guide blocks are symmetrically provided on the left and right side walls of the belt fixing block; the guide blocks are slidably disposed in the guide grooves, thereby guiding the belt fixing block along the guide grooves into the belt mounting groove.

[0009] Furthermore, the fixing base is symmetrically provided with mounting connecting ears on its left and right sides, and the mounting connecting ears are provided with a first through hole for mounting the fixing base.

[0010] Furthermore, the rear side surfaces of the belt mounting groove are respectively a first upper inclined surface, a first middle horizontal surface, and a first lower inclined surface, and correspondingly, the rear side surfaces of the belt fixing block are respectively a second upper inclined surface, a second middle horizontal surface, and a second lower inclined surface; the first upper inclined surface, the first middle horizontal surface, the first lower inclined surface, the second upper inclined surface, the second middle horizontal surface, and the second lower inclined surface are arranged in a one-to-one correspondence.

[0011] Furthermore, the front end of the belt fixing block has two second countersunk holes, which respectively penetrate the second upper inclined surface and the second lower inclined surface. The screw of the belt fixing bolt is installed in the second countersunk hole. At the same time, the rear side of the fixing seat has two third countersunk holes, which respectively penetrate the first upper inclined surface and the first lower inclined surface. The nut of the belt fixing bolt is installed in the countersunk of the third countersunk hole.

[0012] Furthermore, the countersunk head of the third countersunk hole is hexagonal.

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

[0014] Compared to the clamping assembly and the drive belt, the belt mounting structure of this utility model has a horizontal fixing method. The cross-section of the belt mounting groove and the belt fixing block are both trapezoidal. At this time, the belt located in the belt mounting groove is also pressed into a trapezoidal shape, which increases the contact area between the belt and the belt mounting structure. At the same time, the belt fixing bolts that pass through the belt further prevent the belt from shifting relative to the belt mounting structure. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-6 The belt-mounted lifting platform includes a fixed base 1; the fixed base 1 is symmetrically provided with mounting connecting ears 101 on its left and right sides, and the mounting connecting ears 101 are provided with a first through hole 102 for mounting the fixed base 1.

[0023] When using this utility model, the fixing seat 1 can be fixedly installed on the lifting platform by screwing bolts or screws into the first countersunk hole 102 of the mounting connecting ear 101.

[0024] The front end of the fixed base 1 is provided with a belt mounting groove 2, and a belt fixing block 3 is movably disposed in the belt mounting groove 2; both the belt mounting groove 2 and the belt fixing block 3 have trapezoidal cross sections; the fixed base 1 and the belt fixing block 3 are also fixedly connected by belt fixing bolts 4.

[0025] Specifically, the rear side surfaces of the belt mounting groove 2 are a first upper inclined surface 201, a first middle horizontal surface 202, and a first lower inclined surface 203, respectively. Correspondingly, the rear side surfaces of the belt fixing block 3 are a second upper inclined surface 301, a second middle horizontal surface 302, and a second lower inclined surface 303, respectively. The first upper inclined surface 201, the first middle horizontal surface 202, the first lower inclined surface 203, and the second upper inclined surface 301, the second middle horizontal surface 302, and the second lower inclined surface 303 are arranged in a one-to-one correspondence.

[0026] In this design, guide grooves 204 are provided on the left and right side walls of the inner cavity of the belt mounting groove 2; guide blocks 304 are symmetrically provided on the left and right side walls of the belt fixing block 3; the guide blocks 304 are slidably disposed in the guide grooves 204, thereby guiding the belt fixing block 3 to enter the belt mounting groove 2 along the guide grooves 204.

[0027] When using this utility model, the fixing seat 1 is installed on the side of the lifting platform by bolts, holes are drilled in the belt (for the belt fixing bolt 4 to pass through), the belt 9 passes through the belt mounting groove 2, and then the fixing block 3 is pressed into the belt mounting groove 2 to tighten the belt 9. Finally, the belt fixing block 3 is fixed by the belt fixing bolt 4.

[0028] In this design, the front end of the belt fixing block 3 has two second countersunk holes 401, which penetrate the second upper inclined surface 301 and the second lower inclined surface 303 respectively. The screw of the belt fixing bolt 4 is installed in the second countersunk holes 401. Meanwhile, the rear side of the fixing seat 1 has two third countersunk holes 402, which penetrate the first upper inclined surface 201 and the first lower inclined surface 203 respectively. The countersunk head of the third countersunk holes 402 is hexagonal. The nut of the belt fixing bolt 4 is installed in the countersunk head of the third countersunk hole 402. Since the countersunk head of the third countersunk hole 402 is hexagonal and the nut of the belt fixing bolt 4 is a hexagonal nut, the nut of the belt fixing bolt 4 cannot rotate in the third countersunk hole 402, thereby fixing the screw and nut of the belt fixing bolt 4. At the same time, using a countersunk hole to install the nut can keep the rear end of the fixing seat 1 flat, so that the rear end of the fixing seat 1 can fit against the side of the lifting platform, because the side of the lifting platform is generally a vertical plane.
