Description

Technical Field

[0001] The utility model relates to the technical field of reciprocating saw slide rods, in particular to an anti-rotation structure for a reciprocating saw slide rod. Background Art

[0002] A reciprocating saw is a commonly used power tool. The reciprocating saw drives a reciprocating mechanism through a motor to move, making the saw blade perform a reciprocating linear motion, thereby realizing the cutting of materials. Its cutting speed and strength can be controlled by adjusting the motor speed and the stroke of the saw blade.

[0003] The reciprocating saw slide rod is an important component in a reciprocating saw, providing stable guidance for the reciprocating motion of the saw blade, ensuring that the saw blade can move along a straight line during the cutting process, and improving the cutting accuracy and quality.

[0004] In daily work, it is found that the conventional fixed structure of the reciprocating saw slide rod is double-bearing guidance front and back. For cost control, the slide rod uses single-bearing guidance. However, the single-bearing guidance slide rod will have a yaw phenomenon during operation, which will cause the noise and vibration effects of the whole machine to deteriorate, reduce the overall life of the reciprocating saw after long-term use, and affect the use experience. Furthermore, the existing single-bearing guidance slide rod of the reciprocating saw will have a yaw problem that affects normal use when in use. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect of yaw in the prior art that affects normal use, and to propose an anti-rotation structure for a reciprocating saw slide rod.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-rotation structure for a reciprocating saw slide rod, including a reciprocating saw gearbox cover. A slide rod assembly is arranged on the inner wall of the reciprocating saw gearbox cover. A locking assembly is arranged between the reciprocating saw gearbox cover and the slide rod assembly. Two installation grooves are opened on the inner wall of the reciprocating saw gearbox cover, and the two installation grooves are respectively arranged below the end of the slide rod assembly. A support pin is installed on the inner wall of the installation groove, and the support pin is cylindrical. An adjusting assembly is arranged between the reciprocating saw gearbox cover and the support pin. Through the above components, the support pin is placed on the inner wall of the installation groove in the reciprocating saw gearbox cover. The support pin can support the end of the slide rod assembly. When the slide rod assembly performs a reciprocating motion, the support pin can play a supporting role, ensuring the stable effect of the slide rod assembly and reducing the skew phenomenon.

[0007] Preferably, the adjusting component includes a hollow sleeve fixedly connected to the surface of the reciprocating saw gearbox cover. A threaded sleeve is fixedly connected to the surface of the support pin, and the threaded sleeve is slidably connected to the inner walls of both the hollow sleeve and the reciprocating saw gearbox cover. A screw rod is rotatably connected to the inner wall of the hollow sleeve, and the screw rod is threadedly connected to the inner wall of the threaded sleeve. With the above components, by rotating the screw rod, the screw rod can drive the threaded sleeve to move within the hollow sleeve, and the threaded sleeve drives the support pin to move, thereby adjusting the position of the support pin.

[0008] Preferably, one end of the screw rod is fixedly connected to a control head, and a cross slot is provided on the surface of the control head. With the above components, by inserting a tool into the cross slot on the surface of the control head, the control head and the screw rod can be driven to rotate and adjust.

[0009] Preferably, a sealing gasket is provided between the control head and the hollow sleeve, and the sealing gasket is sleeved and connected to the screw rod. With the above components, the sealing gasket can play a role in sealing and protection.

[0010] Preferably, guide blocks are fixedly connected to both ends of the support pin, guide slots are provided on both sides of the installation slot, and the guide blocks are slidably connected to the inner walls of the guide slots. With the above components, when the support pin moves, the guide blocks can move within the guide slots, thereby improving the overall stability effect.

[0011] Preferably, the locking component includes a slide bar pressing plate located above the slide bar assembly. Two pressing screws are provided on the surface of the slide bar pressing plate, and the slide bar pressing plate is installed on the reciprocating saw gearbox cover through the pressing screws. With the above components, the locking screws cooperate with the slide bar pressing plate to press the slide bar assembly, improving stability.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, through this solution, two support pin installation slots are added to the reciprocating saw gearbox cover, and the support pins are placed in the installation slots. The support pins can support the end of the slide bar assembly, thereby reducing the situation of up and down shaking and yaw at the end of the slide bar during operation, realizing the functions of slide bar support and anti-rotation, and further improving the overall stability of the equipment.

[0014] 2. In the present utility model, by setting the adjusting component, the position of the support pin can be adjusted to ensure that the support pin can stably support the slide bar assembly, and stable support can be achieved through adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a reciprocating saw slide bar anti-rotation structure, including a reciprocating saw gearbox cover 1, the inner wall of the reciprocating saw gearbox cover 1 is provided with a slide bar assembly 2, a locking assembly 3 is arranged between the reciprocating saw gearbox cover 1 and the slide bar assembly 2, two installation grooves 4 are opened on the inner wall of the reciprocating saw gearbox cover 1, the two installation grooves 4 are respectively arranged below the end of the slide bar assembly 2, a support pin 5 is installed on the inner wall of the installation groove 4, the support pin 5 is arranged in a cylindrical shape, and an adjusting assembly 6 is arranged between the reciprocating saw gearbox cover 1 and the support pin 5.

[0023] In this embodiment: Place the support pin 5 on the inner wall of the installation groove 4 in the reciprocating saw gearbox cover 1. The support pin 5 can support the end of the slide bar assembly 2. When the slide bar assembly 2 makes a reciprocating motion, the support pin 5 can play a supporting role to ensure the stable effect of the slide bar assembly 2 and reduce the phenomenon of deflection.

[0024] Specifically, the adjusting assembly 6 includes a hollow sleeve 64, the hollow sleeve 64 is fixedly connected to the surface of the reciprocating saw gearbox cover 1, a threaded sleeve 61 is fixedly connected to the surface of the support pin 5, the threaded sleeve 61 is respectively slidably connected to the inner wall of the hollow sleeve 64 and the reciprocating saw gearbox cover 1, a screw 66 is rotatably connected to the inner wall of the hollow sleeve 64, and the screw 66 is threadedly connected to the inner wall of the threaded sleeve 61.

[0025] In this embodiment: Rotate the screw 66. The screw 66 can drive the threaded sleeve 61 to move in the hollow sleeve 64. The threaded sleeve 61 drives the support pin 5 to move, so that the position of the support pin 5 can be adjusted.

[0026] Specifically, one end of the screw 66 is fixedly connected with a control head 65. A cross slot is formed on the surface of the control head 65. By inserting a tool into the cross slot on the surface of the control head 65, the control head 65 and the screw 66 can be driven to rotate and adjust.

[0027] Specifically, a gasket 67 is arranged between the control head 65 and the hollow sleeve 64. The gasket 67 is sleeved and connected with the screw 66. The gasket 67 can play a role in sealing and protection.

[0028] Specifically, guide blocks 62 are fixedly connected to both ends of the support pin 5. Guide slots 63 are formed on both sides of the installation slot 4. The guide blocks 62 are slidably connected to the inner walls of the guide slots 63.
