Description

Technical Field

[0001] The utility model relates to the technical field of elastic belt installation, in particular to an installation tool. Background Art

[0002] Elastic belts are mostly made of multi-strand polyester cores, which have enhanced strength and toughness, high transmission efficiency, automatic buffering, eliminating deformation during transmission, ensuring transmission stability, and significantly reducing noise compared to traditional belts. However, since elastic belts have a greater demand for tension, they are more difficult to install, often requiring two people to coordinate the assembly, resulting in low installation efficiency and labor waste.

[0003] The tooling in the current solution has the same shape as the pulley teeth to fix and limit the belt, and can be adjusted according to different belt thicknesses to meet installation requirements. However, in this solution, since the tooling needs to have the same tooth shape as the pulley teeth, different belt tooth shapes need to match different tooling, and the tooling needs to be replaced frequently during use, which is inconvenient. In addition, the tooling and the pulley are fixed with bolts, which is complicated to operate. Utility Model Content

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments to be described below are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Figure 1This is a schematic diagram of the relative relationship between the installation tool 2 and the pulley 1 in an embodiment of the utility model. The installation tool 2 is fixedly clamped on the side of the pulley 1 to fix the elastic belt on the pulley 1. According to the thickness of the belt and the belt tooth shape, the clamping position of the installation tool 2 can be adjusted in a targeted manner.

[0043] Figure 2 The schematic diagram of the structure of the installation tool 2 in one embodiment of the utility model is shown. The installation tool 2 includes a bracket 21, an outer sleeve 23, an inner sleeve 24 and a handle 22. The bracket 21 has a first plate 211 and a second plate 212 opposite to each other. For ease of installation and carrying, the bracket 21 is U-shaped as a whole. The outer sleeve 23 passes through the first plate 211. The outer sleeve 23 is fixed to the first plate 211 to ensure the stability of the installation tool 2. A smooth through hole is provided inside the outer sleeve 23 to ensure that the inner sleeve 24 slides smoothly in the through hole along the axial direction. Figure 3 As shown, small holes are provided at both ends of the connecting member 25, one end of the connecting member 25 is connected to the outer sleeve 23 through a pin 251, and the other end is connected to the handle 22 through a rotating member 252. The connection parts of the small holes can be rotated, so that the rotating member 252 and the inner sleeve 24 can be driven to move by rotating the handle 22, and the operation is simple and convenient.

[0044] The handle 22 is rotatably connected to the inner sleeve 24 via the rotating member 252. Pulling the handle 22 guides the connecting member 25 to rotate, and drives the inner sleeve 24 to slide in the through hole of the outer sleeve 23, thereby adjusting the relative distance between the inner sleeve 24 and the second plate 212 for easy installation or removal of the installation tool 2.

[0045] like Figure 4 As shown, the installation tool 2 also includes a fixing device 26, which is fixed on the outer sleeve 23 and is used to fix the inner sleeve 24 after the installation tool 2 presses the pulley 1. Specifically, in this embodiment, the fixing device 26 is a hinge locking structure, one of the hinges of the hinge locking structure is L-shaped, and when the inner sleeve 24 presses the pulley 1, the L-shaped hinge of the hinge locking structure is covered on the inner sleeve 24 to prevent the inner sleeve 24 from bouncing up.

[0046] like Figure 2 As shown, a cushion block 242 is provided at one end of the inner sleeve 24 close to the second plate 212. Further, in this embodiment, the inner sleeve 24 also has an adjustment rod 241, and a cushion block 242 is provided at one end of the adjustment rod 241 close to the second plate, and the other end of the adjustment rod 241 is threadedly connected to the inner sleeve 24. The adjustment rod 241 can change its length in the inner sleeve 24 by rotating the thread, thereby adjusting the relative distance between the cushion block 242 and the second plate 212, and changing the length of the adjustment rod 241 can adapt to elastic belts of different widths.

[0047] It is understandable that the adjustment rod 241 and the inner sleeve 24 may also be connected by a snap-fit ​​connection, and the relative distance between the cushion block 242 and the second plate 212 may be adjusted by a limiting structure.

[0048] like Figure 3 As shown, the inner sleeve 24 has a rotating member 252, and the rotating member 252 passes through a hole formed by the connection member 25 and the handle 22. The arrangement of the rotating member 252 allows the inner sleeve 24, the connection member 25 and the handle 22 to rotate relative to each other. The rotating member 252 is a rotating shaft with a Z-shaped structure. When the handle 22 is pulled downward, the inner sleeve 24 has a tendency to move downward. The Z-shaped structure can lift the inner sleeve 24 upward to maintain the smooth movement of the inner sleeve 24.

[0049] It is understandable that the position where the handle 22 is connected to the connecting member 25 and the position where the handle 22 is connected to the rotating member 252 may be different. In this case, the rotating member 252 may be of any shape as long as the handle 22 is rotatably connected to the inner sleeve 24. The connecting member 25 is hingedly connected to the outer sleeve 23 through the pin 251, and the connection of the pin 251 is rotatable.

[0050] like Figure 1-4 As shown, the outer sleeve 23 is processed with threads on the outside, which can be threadedly connected with the first plate 211 to achieve a fixing effect. The outer sleeve 23 is also sleeved with a fixing member 231, which is screwed to fix the outer sleeve 23 and the first plate 211 by screwing. Specifically, in this embodiment, the fixing member 231 includes a nut, and the outer sleeve 23 is fixed to the first plate 211 by tightening the nut.

[0051] How it works:

[0052] like Figure 5 As shown, the initial position of the installation tool 2 is shown. The elastic belt 7 is installed on the water pump pulley 4, the generator pulley 5 and the idler pulley 6 in sequence. The elastic belt 7 is wound around the damping pulley 1 and fixed using the installation tool 2. Figure 6 As shown, the installation tool 2 is installed in the completed position, and the handle 22 is turned to fix the elastic belt 7 on the damping pulley 3. The damping pulley 3 is turned clockwise until it reaches the position shown in the figure, the elastic belt 7 is installed, and the handle 22 is turned to disassemble the installation tool 2 to complete the installation.
