Description

Technical Field

[0001] The utility model relates to the technical field of reciprocating saw balance plates, in particular to a support structure for a reciprocating saw balance plate. Background Art

[0002] With the saw blade that reciprocates at a high speed, a reciprocating saw can easily cut various materials, including wood, metal, plastic, etc. Whether it is a thick wooden board or a hard metal pipe, the reciprocating saw can handle it with ease.

[0003] The reciprocating saw balance plate is a key component in a reciprocating saw, mainly used to balance vibrations. When the reciprocating saw is working, due to the high-speed reciprocating motion of the saw blade, relatively large vibrations will be generated. The balance plate can effectively balance these vibrations, making the reciprocating saw more stable during the working process, reducing the hand fatigue of the operator and the impact on the surrounding environment.

[0004] In daily work, it is found that the existing fixing method of the reciprocating saw balance plate adopts a gearbox housing plus three guide posts structure to guide the balance plate. However, during the use process, it has no function of supporting the balance plate, resulting in abnormal wear of the machine and unstable vibration noise after long-term operation of the balance plate. Furthermore, there is no support structure for the existing reciprocating saw balance plate, and it is prone to wear during use. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages of the existing technology, such as having no support structure and being prone to wear during use, and to propose a support structure for a reciprocating saw balance plate.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A support structure for a reciprocating saw balance plate includes a reciprocating saw gearbox body and a reciprocating saw gearbox cover. The reciprocating saw gearbox cover is arranged above the reciprocating saw gearbox body. The inner wall of the reciprocating saw gearbox body is provided with a reciprocating saw balance plate body. A first guide pin is fixedly connected to the inner wall of the reciprocating saw gearbox body, and the first guide pin is slidably connected to the inner wall of the reciprocating saw balance plate body. Two second guide pins are fixedly connected to the inner wall of the reciprocating saw gearbox body. An installation groove is formed on the surface of the reciprocating saw gearbox cover, and a support pin is arranged on the inner wall of the installation groove. Through the above components, the first guide pin cooperates with the two second guide pins to guide the reciprocating saw balance plate body. At the same time, the two support pins in the reciprocating saw gearbox cover can contact the surface of the reciprocating saw balance plate body, thereby realizing the support of the reciprocating saw balance plate body and improving stability.

[0007] Preferably, the two second guide pins are arranged on both sides of the reciprocating saw balance plate body. Through the above components, the second guide pins are arranged on both sides of the reciprocating saw balance plate body, which can reduce gasket parts and lower the risk of missing installation.

[0008] Preferably, a hollow block is fixedly connected to the surface of the reciprocating saw gearbox cover. A moving plate is slidably connected to the inner wall of the hollow block. Two connecting rods are fixedly connected to the surface of the moving plate. A connecting component is arranged between the connecting rod and the support pin. A transmission screw rod is rotatably connected to the inner wall of the hollow block. The transmission screw rod is threadedly connected to the inner wall of the moving plate. Through the above components, when the transmission screw rod is rotated, the transmission screw rod can drive the moving plate and the connecting rod to move. The connecting rod cooperates with the connecting component to drive the support pin to move and adjust the position to ensure contact with the reciprocating saw balance plate.

[0009] Preferably, one end of the transmission screw rod is fixedly connected with a rotating head, and a slot is formed on the surface of the rotating head. Through the above components, during adjustment, a tool can be inserted into the slot on the surface of the rotating head to drive the transmission screw rod to rotate, improving usability.

[0010] Preferably, the connecting component includes a connecting screw rod. The connecting screw rod is fixedly connected to one end of the connecting rod. A threaded groove is formed on the surface of the support pin. The connecting screw rod is threadedly connected to the inner wall of the threaded groove. Through the above components, the support pin can be connected to the connecting screw rod on the surface of the connecting rod through the threaded groove on its surface, facilitating subsequent disassembly.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. Through this solution, the reciprocating saw balance plate can be supported by two support pins in the reciprocating saw gearbox cover to ensure that the reciprocating saw balance plate is always in a horizontal state during operation, making the vibration and noise of the whole machine more stable.

[0013] 2. Through this solution, the second guide pins on both sides of the reciprocating saw balance plate are externally placed, which can reduce gasket parts and reduce the risk of missing installation. BRIEF DESCRIPTION OF THE DRAWINGS

The surface of the reciprocating saw gear box cover body 2 is provided with an installation groove 6. The inner wall of the installation groove 6 is provided with a support pin 7.

[0021] In this embodiment: The first guide pin 4 cooperates with the two second guide pins 5 to guide the reciprocating saw balance plate body 3. At the same time, the two support pins 7 in the reciprocating saw gear box cover body 2 can contact the surface of the reciprocating saw balance plate body 3, so as to realize the support of the reciprocating saw balance plate body 3 and improve the stability.

[0022] Specifically, the two second guide pins 5 are arranged on both sides of the reciprocating saw balance plate body 3. The second guide pins 5 are arranged on both sides of the reciprocating saw balance plate body 3, which can reduce gasket parts and reduce the risk of missing installation.

[0023] Specifically, the surface of the reciprocating saw gear box cover body 2 is fixedly connected with a hollow block 8.

A connecting component 13 is arranged between the connecting rod 12 and the support pin 7. The inner wall of the hollow block 8 is rotatably connected with a transmission screw 10. The transmission screw 10 is threadedly connected with the inner wall of the moving plate 11.

[0024] In this embodiment: Rotate the transmission screw 10. The transmission screw 10 can drive the moving plate 11 and the connecting rod 12 to move. The connecting rod 12 cooperates with the connecting component 13 to drive the support pin 7 to move and adjust the position to ensure contact with the reciprocating saw balance plate body 3.

[0025] Specifically, one end of the transmission screw 10 is fixedly connected with a rotating head 9. The surface of the rotating head 9 is provided with a slot.

[0026] In this embodiment: During adjustment, a tool can be inserted into the slot on the surface of the rotating head 9 to drive the transmission screw 10 to rotate, improving the ease of use.
