Description

Technical Field

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

[0002] Currently, the existing V-belts are usually reinforced 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 floor area, high transmission efficiency, and low noise, and play an important role in the entire transmission field. The V-belt is widely used in the power transmission of mechanical equipment driven by motors and internal combustion engines. However, the problems of the V-belt mainly include poor heat resistance, large mechanical wear, and inconvenience in stretching. If all the belts on the same belt are not replaced simultaneously during replacement, it will result in differences between the new and old belts in terms of length, causing uneven load distribution on the V-belt, resulting in vibration of the V-belt, unstable transmission, and reduced working efficiency of the V-belt transmission; in the use of V-belts, there are also other problems, such as the belt slipping on the pulley and being unable to transmit power. In addition, if the shape of the belt body changes and the belt slides over the rotating wheel shaft or directly disengages from the rotating wheel shaft, it will cause the equipment to malfunction or even be scrapped, or maintenance is required. More seriously, in extreme environments, overuse of V-belts can cause delamination, tearing, and breakage due to fatigue, wear of the working surface of the belt, torsional vibration of the driven shaft, resulting in equipment damage, reduced production efficiency, and unreliable products, especially in heavy industrial construction equipment and emergency equipment. The problems caused by V-belt transmission can lead to fatal consequences.

[0003] In order to solve the above problems, the Chinese patent application with the publication number CN113124105A discloses a buckle belt, which includes at least three buckle units connected in sequence. Each buckle unit has a connecting body, a bendable support head connecting piece and a limiting support head sequentially connected to its head, and a first insertion hole and a second insertion hole arranged in the front-rear direction. Moreover, the first insertion hole of the buckle unit is sequentially supplied for the limiting support head of the first adjacent buckle unit behind it to insert and be limited; the second insertion hole of the buckle unit is supplied for the limiting support head of the adjacent buckle unit behind it to insert and be limited; the limiting support head and the bendable support head connecting piece of the buckle unit are sequentially inserted into the first insertion hole and the second insertion hole of the buckle unit to achieve locking. In this way, the fitting and clamping degree of both sides of the tightly fitted buckle belt is good, reducing the overall noise during the use of the entire buckle V-belt, and avoiding the extension of the V-belt, thus prolonging its service life.

[0004] However, when the above flexible belt is applied to various fields and usage scenarios, in the transmission fields with high requirements for heavy loads and wear resistance, the flexible belt wears severely, needs to be replaced frequently, and is difficult to meet the requirements of heavy loads. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present utility model provides a triple-plug flexible belt that changes the previous connection method of two sockets to a connection method of three sockets, and adds an additional layer of thickness to enhance the pressure resistance and compressive strength of the flexible belt with snap fasteners.

[0006] The technical solution adopted by the present utility model is as follows: a multi-plug flexible belt with snap fasteners is formed by sequentially inserting and snap-fastening a plurality of flexible buckle units with sockets on its body to form a closed loop. At least three sockets are provided at the body part of each flexible buckle unit, and an integral bending part and a limit buckle part are sequentially provided at the head of the body of each flexible buckle unit; each socket is provided for the integral bending part and the limit buckle part of two adjacent flexible buckle units to be inserted and snap-fastened.

[0007] When several flexible buckle units are sequentially connected and closed and snap-fastened, they are used for transmission or conveyance.

[0008] In this technical solution, the cross-section of the limit buckle part 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.

[0009] In this technical solution, the thickness of the body of the flexible buckle unit is 2-6 mm.

[0010] In this technical solution, at the other end of the side of the body away from the limit buckle part, an inclined chamfer is provided along the belt snap-fastening direction.

[0011] In this technical solution, at least three sockets are arranged at intervals on the body of the flexible buckle unit under the separation of the partition part.

[0012] In this technical solution, each socket is first narrow and then wide from the end of its limit buckle part to the other end.

[0013] In this technical solution, the length of each socket along the conveyor belt direction is greater than the transverse width of the limit buckle part.

[0014] In this technical solution, the length of the bending part is such that after each flexible buckle unit is inserted, it is just snap-fastened and pressed tightly.

[0015] In this technical solution, the flexible buckle unit is formed by thermoplastic molding of a PU composite material and industrial cloth.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 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 buckle is increased. On the other hand, the number of sockets is increased, the buckle 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.

[0018] 2. The thickness of the single-piece active buckle unit has also increased. The buckling flexibility of the thickened active buckle belt remains unchanged, and the buckling flexibility is also the same, thus ensuring its better installation performance and further improving the easy processing performance, wear resistance and service life of the active buckle belt.

[0019] 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 snapping and fastening, which facilitates the active plugging and tightening of the active buckle unit.

[0020] 4. The movable buckle unit is made of PU composite material and industrial cloth thermoplastic molding, so it has good wear resistance and ensures that the bending part and the limit buckle part after processing have good elastic bending performance, while still being able to ensure good ductility and good high temperature resistance.

[0021] To sum up, the multi-link socket-type active buckle belt of the utility model 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 the multi-link socket-type active buckle belt 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.

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the combination or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, during the description of the embodiments of the present invention, for the positional relationships of "upper", "lower", "front", "rear", "left", "right", etc. of all the devices in the drawings, they are all based on Figure 1 as the standard.

[0032] As Figure 1 shown, the multi - joint socket - type flexible buckle belt is formed by sequentially plugging and buckling a plurality of flexible buckle units 10 with sockets 12 on its body 11 to form a closed loop. There are at least three sockets 12 on the body 11 part of each flexible buckle unit 10. An integrated bending part 13 and a limit buckle part 14 are sequentially arranged at the head of the body 11 of each flexible buckle unit 10. Each socket 12 is provided for the integrated bending part 13 and the limit buckle part 14 of two adjacent flexible buckle units 10 to be inserted and buckled for transmission use. After a plurality of flexible buckle units 10 are sequentially connected and closed and buckled, they are used for transmission or conveyance. The overall structural diagram of this multi - joint socket - type flexible buckle belt is shown in Figure 1. Based on the existing body 11 of the flexible buckle unit 10, the detailed structural diagram can be seen in Figure 2 , Figure 3 , directly thickening the belt composed of the original two - socket flexible buckle units as a whole, making its wear - resistance performance stronger, more firm, and with better anti - slip performance. The specific usage effect diagram can be seen in detail in Figure 4 , Figure 5 , Figure 6 and Figure 7 shown.

[0033] In some embodiments, see Figure 2 and Figure 3 As shown, the cross section of the limiting buckle portion 14 is a regular trapezoidal structure. The so-called regular trapezoidal structure 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 to perform transmission work.

[0034] In some embodiments, as Figure 2 、 Figure 3 as well as Figure 4 As shown, the thickness of the body 11 of the active buckle unit 10 is 2-6 mm, and the preferred embodiment is 3 mm, 3.5 mm, 4 mm, 4.2 mm, 4.5 mm, 5 mm, 6 mm and the like. The active buckle units 10 of these thicknesses can simultaneously 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 that is easy to process and install and has relatively suitable wear resistance, shear resistance and tensile resistance, so that it can have a higher cost-effectiveness in specific transmission and transmission scenarios.

[0035] In some embodiments, as Figure 2 As shown, the side surface of the main body 11 is provided with an oblique chamfer 15 along the belt buckling direction away from the other end of the limit buckle portion 14. 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.

[0036] In at least some embodiments, 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, thereby realizing a tight engagement with the limiting 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 the movable gasket is suitable for use in transmission devices that require precise installation clearance between the limit buckle part 14 and the socket 12.

[0037] 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 movable buckle unit 10 can be easily inserted into the socket 12 of another movable buckle unit 10. After insertion, the relative positions between the two movable buckle units 10 are adjusted to prevent the engaged movable 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 then a rectangular structure as shown in the figure.

[0038] 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 at the same time, the active buckle unit 10 inserted into the socket 12 can be easily adjusted and can be taken out at any time.

[0039] In some embodiments, the length of the bent portion 13 is such that each of the active buckle units 10 is inserted and tightly fastened, thereby ensuring that each of the active buckle units 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 As can be seen from the connected buckle belt, the thickness of the connected belt will vary greatly due to the different number of sockets. Based on the structure and material properties, it can be inferred that there will be certain differences in the 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 to meet the respective technical requirements when used.

[0040] In some embodiments, the movable 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 limiting 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.

[0041] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
