[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0026] The embodiment of the present application provides a connection mechanism with adjustable gap and easy disassembly, which can solve the problem in the related art that it is difficult to achieve both proper adjustment of the gap and stable connection between the top cover connecting member and the lifting device connecting member.

[0027] Since there will be a certain gap between the top cover and the lifting device due to the natural deformation of the top cover during the connection between the top cover and the lifting device, which will not only increase the installation difficulty of the top cover and the lifting device but also pose certain potential safety hazards; then a connection mechanism that can be easily disassembled and whose gap between the top cover connecting member and the lifting device connecting member can be flexibly adjusted is designed.

[0028] Reference Figures 1-6 , a connection mechanism with adjustable gap and easy disassembly, which includes: a first connecting member 1, on which a fixed cylinder 4 is provided; an adjusting column 5, which is threadedly connected in the fixed cylinder 4 and vertically provided with an adjusting clamping groove 52 and a connecting groove 51; a second connecting member 2, which is connected to the top of the adjusting column 5 through a locking member 3 and the connecting groove 51.

[0029] Through this structural design, the first connecting member 1 is provided with a fixing cylinder 4 for accommodating the adjusting column 5, providing a spatial basis for adjusting the gap between the connecting members. The adjusting column 5 is connected to the inner wall of the fixing cylinder 4 by a threaded structure, facilitating height adjustment. The second connecting member 2 is arranged inside the adjusting column 5, thus realizing the adjustment of the distance between the first connecting member 1 and the second connecting member 2. An adjusting card slot 52 is arranged vertically along the adjusting column 5. When adjusting the gap, insert the rotating rod into the adjusting card slot 52 and rotate it to complete the adjustment of the height position of the adjusting column 5 inside the fixing cylinder 4. The connecting slot 51 is used to connect the second connecting member 2, providing a turning-in space for the locking member 3. The locking member 3 cooperates with the connecting slot 51 to tightly abut the second connecting member 2 against the top surface of the adjusting column 5, thus realizing the stable connection between the first connecting member 1 and the second connecting member 2, and solving the problem in the related art that it is difficult to achieve both proper adjustment of the gap and stable connection between the top cover connecting member and the lifting device connecting member.

[0030] In some preferred embodiments, it further includes a rotating rod, which is used to insert into the adjusting card slot 52 to drive the adjusting column 5 to approach or move away from the first connecting member 1. The adjusting card slot 52 is located at the port of the adjusting column 5 close to the first connecting member 1, and the connecting slot 51 is located at the port of the adjusting column 5 far from the first connecting member 1. The adjusting card slot 52 communicates with the connecting slot 51.

[0031] This embodiment adds a rotating rod, which is used to insert into the adjusting card slot 52 and drive the adjusting column 5 to move by rotation, thereby adjusting the distance between it and the first connecting member 1. The operator can apply a rotational force to the rotating rod to drive the adjusting column 5 to move in the direction of approaching or moving away from the first connecting member 1. The adjusting card slot 52 is located at the port of the adjusting column 5 close to the first connecting member 1, mainly used to assist the rotating rod to rotate the adjusting column 5. The connecting slot 51 is located at the port of the adjusting column 5 far from the first connecting member 1, so as to use the locking member 3 to lock and fit the second connecting member 2 to the top of the adjusting column 5. There is a communication relationship between the adjusting card slot 52 and the connecting slot 51, that is, the rotating rod can pass through the connecting slot 51 and insert into the adjusting card slot 52.

[0032] In some preferred embodiments, the cross-sectional area of the notch of the adjusting card slot 52 is smaller than the cross-sectional area of the notch of the connecting slot 51.

[0033] With this structural setting, since the adjusting card slot 52 communicates with the connecting slot 51, in order to ensure that the rotating rod can extend into the adjusting card slot 52 from the other end face of the adjusting column 5, it needs to pass through the connecting slot 51. Therefore, it should be ensured that the notch of the connecting slot 51 is larger than the notch of the adjusting card slot 52 to ensure that the rotating rod can pass through the connecting slot 51 smoothly.

[0034] In some preferred embodiments, the adjustment slot 52 vertically penetrates the adjustment column 5 and is coaxial with the central axis of the adjustment column 5; a plurality of connection slots 51 are provided on the end face of the adjustment column 5 away from the first connecting member 1, and the plurality of connection slots 51 are annularly distributed with the adjustment slot 52 as the center; the second connecting member 2 is provided with an adjustment through hole 21 and a first connection through hole, and the adjustment through hole is for the rotating rod to extend into the adjustment slot 52.

[0035] Through this structural design, the vertically penetrating design of the adjustment column 5 provides a convenient adjustment method, enabling the adjustment column 5 to centrally adjust the distance between the connecting members. The adjustment slot 52 is located at the center of the column, ensuring the symmetry and stability of the adjustment; the plurality of connection slots 51 are annularly distributed around the adjustment slot 52. Such a design enhances the stability after adjustment, effectively disperses the stress at each connection point, and improves the stability and load-bearing capacity of the overall structure. The connection slots 51 and the adjustment slot 52 are independently arranged, so that after the bolt is fixed, it does not affect the connection of the rotating rod to the adjustment slot 52, thereby realizing the independent adjustment of the relative position of the adjustment column 5 and adjusting the distance between the first connecting member 1 and the second connecting member 2. The adjustment through hole 21 on the second connecting member 2 provides convenience for connection and adjustment, enabling the rotating rod to smoothly extend into the adjustment slot 52. Such a design enables easy fine-tuning to be carried out even after assembly is completed, meeting the requirements in different usage environments. The locking member 3 is in the form of a bolt and is connected to the adjustment slot 52 by passing through the first connection through hole, which can effectively fix the position of the adjustment column 5 and lock the second connecting member 2 to ensure the stability of the device. The design of multiple bolts improves the firmness of the connection, disperses the stress, and ensures the stability of the structure. The combined design of the adjustment column 5 and the adjustment slot 52 enables the operator to quickly and easily adjust the distance between the connecting members to adapt to specific usage requirements. The annularly distributed connection slots 51 ensure that during the adjustment process, the stress distribution at each connection point is uniform, reducing the potential risk of local deformation and enhancing the durability of the overall structure. This design takes into account the convenience of maintenance. The adjustment through hole 21 enables necessary adjustments to be made even after assembly is completed without completely disassembling the device, saving time and resources. This adjustment design mechanism can be effectively applied in various mechanical equipment, automation devices, and engineering applications that require dynamic adjustment. For example, the connection of robotic arms, the adjustment of conveyor belts, the connection of building structures, etc. can all be precisely and flexibly controlled through such a design.

[0036] In some preferred embodiments, the cross-section of the adjustment slot 52 is a regular hexagon; or, the cross-section of the adjustment slot 52 is a regular octagon.

[0037] This embodiment further defines the shape and structure of the adjustment slot 52, and designs the cross-section of the adjustment slot 52 into a general structure such as a regular hexagon or a regular octagon, which can ensure that the rotating rod can be adapted to it. The notches of these two polygonal shapes can effectively prevent the sliding or adverse rotation of the rotating rod after it enters, because the geometric structure of the polygon makes the force transmission more evenly distributed, improving the smoothness of rotation. This design is not only applicable to a specific type of rotating rod, but also can be adapted to a variety of tools and devices, expanding the scope of application of the design and enhancing the versatility of the product.

[0038] In some preferred embodiments, one end of the rotating rod is a regular hexagonal cylinder structure, and the other end is a regular octagonal cylinder structure to be adapted to the adjustment slot 52.

[0039] Through this structural design, different polygonal shapes (regular hexagon and regular octagon) are adopted at both ends of the rotating rod, so that it can be flexibly adapted to various types of adjustment slots 52. The operator can select a suitable port for connection according to actual needs, broadening the usage scenarios and reflecting its bidirectional adaptability; the design of the polygonal shape provides more gripping surfaces, making the rotating rod more stable during use, and the operator can apply force more accurately during operation, reducing the risk of failure caused by sliding.

[0040] In some preferred embodiments, the locking member 3 is a bolt; the second connecting member 2 is provided with a second connecting through hole; the connecting groove 51 is a threaded hole structure, and the bolt passes through the second connecting through hole and is connected to the connecting groove 51 to tightly attach and hold the second connecting member 2 to the top of the adjusting column 5.

[0041] Through this structural design, choosing a bolt as the locking member 3 helps to achieve precise fastening and adjustment. The application of the bolt ensures the firmness of the connection and is easy to disassemble and reinstall when needed. The second connecting through hole provided on the second connecting member 2 facilitates the passing and fixing of the bolt, ensuring the effectiveness of the connection. In addition, this design can adapt to adjusting columns 5 of different thicknesses, enhancing compatibility. The connecting groove 51 adopts a threaded hole structure, and the bolt is connected to the connecting groove 51 through the second connecting through hole, thereby tightly attaching and fixing the second connecting member 2 to the top of the adjusting column 5, simply realizing the indirect fixed connection between the first connecting member 1 and the second connecting member 2.

[0042] In some preferred embodiments, an elastic washer 6 is provided between the nut of the bolt and the second connecting member 2.

[0043] With this structural arrangement, the elastic washer 6 is made of rubber or other highly elastic materials, and its main functions are shock absorption, buffering, and sealing. Adding an elastic washer between the connected nut and the second connecting member 2 helps reduce stress concentration at the connection site and prevent fatigue failure in a load-changing or vibrating environment. The elastic washer 6 serves to protect the connection surface, preventing the nut from causing direct physical damage to the second connecting member 2 and enhancing the service life of the connection components. The elastic material has good sealing performance, can form a reliable seal at the connection, prevent the intrusion of dust, moisture, or other external substances, and contribute to the long-term stable operation of the device. Adding the elastic washer 6 can help disperse the torque applied to the nut, making the pressure more evenly distributed to the connecting members, thereby reducing the risk of potential connection failure.

[0044] In some preferred embodiments, a flat washer 7 is provided between the elastic washer 6 and the second connecting member 2.

[0045] With this structural design, the flat washer 7 is made of metal or other hard materials, and its main function is to disperse the load applied to the connecting components and prevent local deformation or damage to the second connecting member 2 when the bolt head or nut is tightened. The buffering and sealing functions provided by the elastic washer 6 are combined with the rigidity and pressure-bearing capacity of the flat washer 7 to form a composite connection that can cope with more complex working environments and conditions. When the elastic washer 6 and the flat washer 7 are used in combination, the performance of the connection structure is significantly improved. Through reasonable design and material selection, this combination not only achieves the optimization of load distribution and sealing but also enhances the durability of the connection.

[0046] In some preferred embodiments, the fixing cylinder 4 has a designed height L.

[0047] In this embodiment, by selecting fixing cylinders 4 of different heights, the minimum distance between the first connecting member 1 and the second connecting member 2 can be controlled; by reasonably adjusting this height, the required minimum distance can be ensured during installation to meet the required engineering standards and ensure the reliability of the structure under different working conditions. In applications in compact spaces, by controlling the minimum distance, the overall structural layout can be optimized and the space utilization rate can be improved.

[0048] The beneficial effects brought by the present utility model include:

[0049] The first connecting member 1 is provided with a fixing cylinder 4 for accommodating the adjusting column 5, providing a spatial basis for adjusting the gap between the connecting members. The adjusting column 5 is connected to the inner wall of the fixing cylinder 4 by a threaded structure, facilitating height adjustment. The second connecting member 2 is disposed within the adjusting column 5, thus realizing the adjustment of the distance between the first connecting member 1 and the second connecting member 2. An adjusting slot 52 is provided vertically along the adjusting column 5. When adjusting the gap, the rotating rod is inserted into the adjusting slot 52 and rotated, and the height position of the adjusting column 5 within the fixing cylinder 4 can be adjusted. The connecting slot 51 is used to connect the second connecting member 2, providing a turning-in space for the locking member 3. The locking member 3 cooperates with the connecting slot 51 to tightly abut the second connecting member 2 against the top surface of the adjusting column 5, thus realizing the stable connection between the first connecting member 1 and the second connecting member 2, and solving the problem in the related art that it is difficult to appropriately adjust the gap and stably connect between the top cover connecting member and the lifting device connecting member.
