Description

Technical Field

[0001] The invention relates to the technical field of flexible buckle transmission and transportation, in particular to a multi-joint socket type flexible buckle belt. Background Art

[0002] At present, the existing V-belts are usually reinforced materials combined with vulcanized rubber and steel. The existing V-belts are divided into two categories: special core V-belts and ordinary V-belts. Compared with flat transmission belts, they have the advantages of easy installation, small footprint, high transmission efficiency and low noise, and occupy an important position in the entire transmission field. The V-belt is widely used in power transmission of mechanical equipment driven by electric motors and internal combustion engines, but the problems of the V-belt are mainly poor heat resistance, large mechanical wear and tear, and inconvenient stretching. If all belts on the same belt are not replaced at the same time, the new and old belts will be different, and the lengths will be different, which will make the load distribution on the V-belt uneven, causing the V-belt to vibrate and the transmission to be unstable, thus reducing the working efficiency of the V-belt transmission. In the use of the V-belt, there are also other problems, such as the belt slipping on the pulley and causing the inability to transmit power. In addition, if the shape of the belt body changes, the belt slips over the rotating axle or directly detaches from the rotating axle, the equipment will not be able to be used normally or even be scrapped, or it must be repaired and maintained. What is more serious is that in extreme environments, excessive use of the V-belt will cause delamination, tearing and breaking due to fatigue, wear of the working surface of the belt, and torsional vibration of the driven shaft, which will cause equipment damage, reduce production efficiency, and cause product unreliability, especially in heavy construction equipment and emergency equipment. Problems caused by V-belt transmission will produce fatal consequences.

[0003] In order to solve the above problems, a Chinese patent application with publication number CN113124105A discloses an active buckle belt, comprising at least three active buckle units that are sequentially buckled and connected, each active buckle unit having a connecting body and a bendable support head connecting piece and a limit support head that are sequentially connected to its head, and a first through hole and a second through hole arranged along the front-to-back direction, and the first through hole of the active buckle unit is sequentially provided for the limit support head of the first active buckle unit adjacent thereto to be inserted and used for limiting; the second through hole of the active buckle unit is provided for the limit support head of the active buckle unit adjacent thereto to be inserted and used for limiting; the limit support head and the bendable support head connecting piece of the active buckle unit are sequentially inserted into the first through hole of the active buckle unit and the second through hole of the active buckle unit to achieve locking, so that the two sides of the active buckle belt that is fitted and clamped in this way have a good fitting and clamping degree, so that the noise of the entire active buckle V-belt during use is reduced as a whole, and the extension of the V-belt is avoided, thereby extending its service life.

[0004] However, when the above-mentioned flexible-joint belts are put into use in various fields and usage scenarios, in the transmission field with heavy load and high wear resistance requirements, the flexible-joint belts are severely worn and replaced more frequently, which makes it difficult to meet the heavy load requirements. Summary of the invention

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a triple-plug active belt which changes the previous two-plug connection mode into a three-plug connection and increases the thickness by one layer to enhance the pressure resistance and compressive strength of the active buckle belt.

[0006] The technical solution adopted by the present invention is: a multi-joint socket-type active buckle belt, which is formed by a plurality of active buckle units with sockets arranged on its body, which are sequentially inserted and buckled into a closed loop, each of the active buckle units has at least three sockets on its body, and each of the active buckle units is sequentially provided with an integral bending portion and a limiting buckle portion on its body head; each of the sockets is provided with an integral bending portion and a limiting buckle portion of two adjacent active buckle units for insertion and buckling; The movable buckle units are connected and closed in sequence for transmission or delivery.

[0007] In the present technical solution, the cross section of the position-limiting buckle portion is a regular trapezoidal structure, and the so-called regular trapezoidal structure is a structure with a short upper base and a long lower base.

[0008] In the present technical solution, the thickness of the body of the active buckle unit is 2-6 mm.

[0009] In the technical solution, the other end of the side surface of the main body away from the limiting buckle portion is provided with an oblique chamfer along the belt buckling direction.

[0010] In the technical solution, at least three of the sockets are arranged at intervals on the body of the active buckle unit under the separation of the partition part.

[0011] In the technical solution, each of the sockets is narrow at first and then wide from the end of its limit buckle portion to the other end.

[0012] In the technical solution, the length of each of the insertion openings along the conveyor belt direction is greater than the lateral width of the limiting buckle portion.

[0013] In the technical solution, the length of the bending portion is based on the fact that each active buckle unit is inserted and tightly fastened.

[0014] In the technical solution, the movable buckle unit is formed by thermoplastic molding of PU composite material and industrial cloth.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The number of sockets of the active buckle unit is increased. On the one hand, the overall thickness of the active buckle belt formed by the buckling is increased. On the other hand, the number of sockets is increased, the buckling is tighter, and the tensile strength of the active buckle belt is stronger, thereby improving the overall thickness, tensile strength, shear strength and wear resistance of the active buckle belt, and expanding its scope of use.

[0016] 2. The thickness of the single-piece active buckle unit has also increased. The buckling flexibility and flexibility of the thickened active buckle belt remain unchanged, thus ensuring better installation performance and further improving the processing performance, wear resistance and service life of the active buckle belt.

[0017] 3. At least three of the sockets are arranged at intervals on the body of the active buckle unit under the separation of the partition part. The use of the partition part realizes the integrated setting of snap-fitting and fastening, which facilitates the active plugging and tightening of the active buckle unit.

[0018] 4. The active buckle unit is formed by thermoplastic molding of PU composite material and industrial cloth, so it has good wear resistance and ensures that the bending part and the limit buckle part have good elastic bending performance after processing, and can still ensure good ductility and high temperature resistance.

[0019] To sum up, the multi-link socket type active buckle belt of the present invention improves the overall thickness, tensile and shear resistance, high temperature resistance and wear resistance of the active buckle belt, and is adapted to the use range of multi-link socket type active buckle belts in the transmission field with heavy load and high wear resistance requirements, and has high tensile and shear resistance, high temperature resistance and high wear resistance.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, in the description of the embodiments of the present invention, the device positional relationships such as "up", "down", "front", "back", "left", "right" and the like in all the drawings are based on the positions or positional relationships shown in the accompanying drawings. Figure 1 As standard.

[0023] like Figure 1 As shown, a multi-linked socket-type active buckle belt is formed by a plurality of active buckle units 10 with sockets 12 arranged on its main body 11, which are sequentially inserted and buckled into a closed loop. The main body 11 of each active buckle unit 10 has at least three sockets 12, and the head of the main body 11 of each active buckle unit 10 is sequentially provided with an integral bending portion 13 and a limiting buckle portion 14; each of the sockets 12 is provided with the integral bending portion 13 and the limiting buckle portion 14 of the two adjacent active buckle units 10 for use in transmission after being inserted and buckled, and the active buckle units 10 are sequentially connected and closed for transmission or delivery. The overall structure of the multi-linked socket-type active buckle belt is shown in FIG. Figure 1 As shown, the main body 11 of the existing active buckle unit 10 can be used as the basis. The detailed structural diagram can be found in Figure 2 , Figure 3 , directly thicken the original belt composed of two sockets and buckles, making it more wear-resistant, firmer and more anti-slip. For details, see the specific effect diagram Figure 4 , Figure 5 , Figure 6 and Figure 7 shown.

[0024] In some embodiments, see Figure 2 and Figure 3As shown, the cross-section of the limiting buckle portion 14 is a regular trapezoidal structure, which is a structure with a short upper base and a long lower base, so that the limiting buckle portion 14 can be better limited after being inserted into the socket of the adjacent active buckle unit 10, thereby preventing the active buckle unit 10 from slipping and ensuring that they are tightly combined for transmission.

[0025] In some embodiments, Figure 2 , Figure 3 as well as Figure 4 As shown, the thickness of the body 11 of the active buckle unit 10 is 2-6mm, and the preferred implementation is 3mm, 3.5mm, 4mm, 4.2mm, 4.5mm, 5mm, 6mm and the like. The active buckle units 10 of these thicknesses can take into account the thickness of the body 11 of the active buckle unit 10, the length of the body 11 of the active buckle unit 10, and the number of sockets 12 of the body 11 of the active buckle unit 10, so as to obtain an active buckle belt which is easy to process and install and has suitable wear resistance, shear resistance and tensile resistance, so that it can have a higher cost-effectiveness in specific transmission and transmission scenarios.

[0026] In some embodiments, Figure 2 As shown, the other end of the side of the main body 11 away from the limiting buckle portion 14 is provided with an oblique chamfer 15 along the belt buckling direction. The setting of the oblique chamfer 15 ensures that after the active buckle belt is connected, it is relatively smooth in the tangential direction of the active buckle belt, so that during the installation and maintenance process, the safety of the installation and maintenance personnel can be ensured, thereby avoiding unnecessary safety accidents.

[0027] In at least some embodiments, from Figure 2 and Figure 3 , Figure 4 It can be seen that at least three of the sockets 12 are arranged at intervals on the body 11 of the active buckle unit 10 under the separation of the partition part 16, so as to achieve a tight engagement with the limit buckle part 14 of the adjacent active buckle unit 10. In the specific implementation process, the connection mode of the partition part 16 can be an integrated structure formed with the body 11 of the active buckle unit 10, or it can be a movable partition part adjusted by a movable gasket, such as Figure 3 As shown; the two structures have their own advantages. The former integrated structure is suitable for requirements of short processing cycle and convenient and quick installation, and the latter movable partition part adjusted by movable gasket is suitable for use in transmission devices that require precise installation clearance between the limit buckle part 14 and the socket 12.

[0028] In other embodiments, Figure 4As shown, each of the sockets 12 is narrow at first and then wide from its limiting buckle portion 14 end to the other end, so that the limiting buckle portion 14 of one active buckle unit 10 can be easily inserted into the socket 12 of another active buckle unit 10. After insertion, the relative positions of the two active buckle units 10 are adjusted to prevent the engaged active buckle units 10 from sliding, thereby ensuring that they can be clamped and ensuring their working stability. A specific embodiment can be a trapezoidal structure first and a rectangular structure later as shown in the figure.

[0029] In some embodiments, the length of each socket 12 along the conveyor belt direction is greater than the lateral width of the limiting buckle portion 14, thereby ensuring that the limiting buckle 14 can be easily inserted into the socket 12, and the active buckle unit 10 inserted into the socket 12 can be easily adjusted and can be taken out at any time.

[0030] In some embodiments, the length of the bending portion 13 is such that each active buckle unit 10 is inserted and tightly fastened, thereby ensuring that each active buckle unit 10 can always remain tight and not loose during transmission. Figure 2 and Figure 3 The structure of the active buckle unit 10 of the triple socket and the active buckle unit 10 of the quadruple socket is shown in FIG. Figure 5 and Figure 6 It can be seen from the connected buckle belt that the thickness of the connected belt will be very different due to the different number of sockets. From the structure and material properties, it can be inferred that there will be certain differences in its specific performance. During use, the number of sockets 12 and the thickness of the body 11 can be selected according to different application scenarios, thereby forming different buckle units 10 so that they can meet their respective technical requirements when used.

[0031] In some embodiments, the active buckle unit 10 is formed by thermoplastic molding of PU composite material and industrial cloth, so as to achieve better wear resistance and ensure that the limited support head and the bendable support head connecting piece have good elastic bending performance after processing, while still being able to ensure good ductility and good high temperature resistance.

[0032] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
