Description

Technical Field

[0001] The utility model relates to the technical field of synchronous belts, in particular to a modular end head assembly with adjustable tension for synchronous belts. Background Art

[0002] Synchronous belt is a synchronous toothed belt, also known as timing belt. It is similar to common belt transmission methods such as V-belts and flat belts, and is a flexible transmission form. Synchronous toothed belts use steel wire ropes or glass fiber ropes as a strong layer, and are covered with polyurethane or chloroprene rubber on the outside. The inner circumference of the belt is made into a tooth shape so that it meshes with the toothed belt pulley. Since the strong layer has little deformation after bearing, the circumference of the toothed belt can be kept unchanged, so there is no relative slip between the belt and the pulley, thereby ensuring synchronous transmission and a constant transmission ratio. For transmissions that require synchronization, it can also be used for low-speed transmission;

[0003] Among them, there is an open synchronous belt, which is made of thermoplastic polyurethane material and has high wear resistance. Various types of steel wire cores ensure that it still maintains good operation ability in high-load transmission. The open belt in the synchronous belt is usually used for linear motion transmission devices. The open synchronous belt has different connection methods. One of them is a bolt connection. This connection method connects the hub and pulley of the open synchronous belt with bolts, which is easy to install and disassemble. It is suitable for high-load operation and occasions that are not easy to slant, but the mechanical properties are relatively poor. When used specifically, the two ends of the open synchronous belt are fixed by punching holes at the ends and tightening them with screws.

[0004] When installing a conventional synchronous belt, a special auxiliary installation tool is required to engage it with the driving gear of the equipment, which makes the convenience and flexibility of the entire installation operation relatively limited.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a modular end head assembly with adjustable tension of the synchronous belt is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a modular end head assembly with adjustable tension of a synchronous belt, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modular terminal assembly with adjustable tension of a synchronous belt, comprising a main belt body and a docking terminal, the surface of the main belt body is provided with a tooth shape, the docking terminal is arranged at one end of the main belt body, and an adjustment block is inserted inside the docking terminal, and a connecting terminal is arranged at the end of the main belt body away from the docking terminal, the docking terminal comprises an terminal slot, a first connecting hole, a docking socket and a second connecting hole, the first connecting hole is opened on both sides of the left and right sides of the terminal slot, and a docking socket is arranged below the terminal slot, and a second connecting hole is opened horizontally in the middle of the docking socket.

[0008] Furthermore, the main belt body and the tooth shape are arranged as an integral structure, and the adjustment block is movably connected to the main belt body.

[0009] Furthermore, the internal structural dimensions of the terminal slot match the outer surface structure of one end of the adjustment block, and the first connecting holes are arranged equidistantly on the left and right sides of the terminal slot.

[0010] Furthermore, holes with the same structure as the first connecting hole are arranged equidistantly in the middle of the adjustment block, and the diameters of the first connecting hole and the second connecting hole are the same.

[0011] Furthermore, the connecting end includes a docking plug, a first connecting hole, a connecting socket and a second connecting hole. The first connecting hole is horizontally opened in the middle of the docking plug, and the connecting socket is arranged above the docking plug, and the second connecting hole is opened on the side of the connecting socket.

[0012] Furthermore, the outer surface structure of the docking block matches the outer surface structure of the docking socket, and the internal structure of the docking socket matches the surface structure of one end of the adjustment block away from the end slot, and the first connecting hole and the second connecting hole have the same structural dimensions.

[0013] Furthermore, a first connecting anchor rod is horizontally penetrated through the upper side of the connecting end, and a second connecting anchor rod is horizontally penetrated through the lower side of the connecting end.

[0014] Furthermore, the hole diameters of the first connection hole and the second connection hole match the diameter of the first connection anchor rod, and the hole diameters of the second connection hole and the first connection hole match the diameter of the second connection anchor rod.

By using the above structure, the stability and firmness of the overall structural connection can be ensured to the greatest extent when the front and rear ends of the main belt body are docked and combined.

[0018] 2. The utility model, by equidistantly arranging a hole structure matching the diameter of the first connecting anchor rod in the middle of the adjustment block, cooperates with the first connecting holes symmetrically opened on both sides of the end slot, and the second connecting holes opened on both sides of the connecting socket, and uses the first connecting anchor rod to be horizontally inserted into the structural holes of any group as needed, so that when the two ends of the main belt body are butted, adjustments can be made within a certain range.
