[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a transmission shaft for a grinding head. The transmission shaft for the grinding head includes a disassembly and assembly component 200. The disassembly and assembly component 200 controls the engagement and disassembly of the locking block 202 and the locking groove 203, so that the dustproof threaded tube 103 can be quickly disassembled and assembled without special tools.

[0032] The main structure 100 includes a bushing 101, a shaft 102 at the bottom of the bushing 101, a dustproof threaded tube 103 covering the surface of the shaft 102, and a housing 104 fixedly connected to the bottom of the surface of the bushing 101, the bottom of the housing 104 being open; and...

[0033] The assembly 200 is located in the inner cavity of the housing 104. It includes an embedding groove 201 at the bottom of the inner cavity of the bushing 101. Both sides of the inner cavity of the embedding groove 201 are slidably connected to the locking blocks 202. The top of the surface of the dustproof threaded tube 103 is provided with a locking groove 203, which cooperates with the locking blocks 202. A mounting plate 204 is fixedly connected to one side of the bushing 101. A power component 205 is provided at the bottom of the mounting plate 204, and a limit component 206 is provided at the top of the power component 205.

[0034] In the main structure 100, the bushing 101 and the shaft body 102 serve as the main frame of the transmission shaft; the dustproof threaded tube 103 is sleeved on the surface of the shaft body 102 to achieve dynamic sealing and prevent metal shavings and dust from entering the interior of the transmission shaft.

[0035] The assembly / disassembly component 200 enables the quick assembly / disassembly of the dustproof threaded tube 103 through the sliding engagement of the embedded groove 201 and the locking block 202. The annular snap-fit ​​design of the groove 203 and the locking block 202 replaces the traditional bolt connection, avoiding the need for special tools (the problem of cumbersome bolt assembly / disassembly in the prior art). The power component 205 and the limiting component 206 work together to drive the locking block 202 to extend and retract within the embedded groove 201, thereby locking or releasing the dustproof threaded tube 103. This solves the problems of low maintenance efficiency and complex operation in the prior art. The mounting plate 204 provides fixed support for the power component 205, ensuring transmission stability.

[0036] Example 2

[0037] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the power component 205 includes a fixed block 205a disposed at the bottom of the mounting plate 204. The inner cavity of the fixed block 205a is rotatably connected to a lead screw 205b via a bearing. One side of the lead screw 205b is rotatably connected to the bushing 101 via a bearing. A movable block 205c is threadedly connected to the surface of the lead screw 205b. Movable rods 205d are hinged to both sides of the movable block 205c. A connecting rod 205e is hinged to one side of the movable rod 205d. A horizontal plate 205f is hinged to one side of the connecting rod 205e. One side of the horizontal plate 205f is fixedly connected to the locking block 202.

[0039] The power component 205 converts rotational motion into linear displacement of the movable block 205c via a threaded transmission between the lead screw 205b and the movable block 205c. The hinged structure between the movable rod 205d and the connecting rod 205e pushes the horizontal plate 205f to move laterally, causing the locking block 202 to engage or disengage from the locking slot 203. This design achieves single-handed operation through mechanical linkage, allowing for the assembly and disassembly of the dustproof threaded tube 103 without tools, thus solving the problem of relying on tools such as Allen wrenches in the prior art.

[0040] Specifically, the other side of the lead screw 205b passes through the housing 104 and is fixedly connected to a handle 205g, and a protrusion is fixedly connected to one side of the handle 205g.

[0041] The handle 205g is fixed to the end of the lead screw 205b, and the protrusion increases friction, making it easy to manually rotate the lead screw 205b. Operators can control the extension and retraction of the locking block 202 by turning the handle 205g without the need for tools such as wrenches, further simplifying the maintenance process.

[0042] Specifically, the bushing 101 has a sliding groove 205h on both sides, which cooperates with the horizontal plate 205f.

[0043] The slide groove 205h is formed on both sides of the bushing 101 to provide a straight guide path for the horizontal plate 205f, ensuring that the horizontal plate 205f remains horizontal during movement, avoiding misalignment between the locking block 202 and the locking groove 203, and improving the accuracy and reliability of disassembly and assembly.

[0044] Specifically, the connecting rod 205e is hinged to the fixing block 205a, and the top of the fixing block 205a is fixedly connected to the mounting plate 204.

[0045] The connecting rod 205e is hinged to the fixing block 205a, and the top of the fixing block 205a is fixed to the mounting plate 204, forming a stable triangular support structure to distribute the transmission load of the power component 205 and prevent the lead screw 205b from being deformed by force.

[0046] Specifically, the limiting component 206 includes a limiting buckle 206a fixedly connected to the top of the horizontal plate 205f, a limiting rod 206b slidably connected to the inner cavity of the limiting buckle 206a, and one side of the limiting rod 206b fixedly connected to the bushing 101.

[0047] The limiting member 206 restricts the movement range of the horizontal plate 205f through the sliding engagement of the limiting buckle 206a and the limiting rod 206b, preventing the locking block 202 from over-extending and causing damage to the locking groove 203, while ensuring the complete engagement of the locking block 202 and the locking groove 203.

[0048] Specifically, a spring 202a is fixedly connected to one side of the card block 202. One side of the spring 202a is fixedly connected to one side of the inner cavity of the embedding groove 201. There are multiple sets of springs 202a, which are evenly distributed on one side of the card block 202.

[0049] Spring 202a is installed between the locking block 202 and the embedded groove 201 to provide elastic restoring force, while multiple sets of evenly distributed springs 202a ensure that the locking block 202 is subjected to uniform force, avoiding wear caused by stress concentration at a single point.

[0050] Specifically, both the card block 202 and the card slot 203 are annular, and the other side of the card block 202 is in contact with the inner cavity of the card slot 203.

[0051] The ring-shaped design of the locking block 202 and the locking groove 203 maximizes the contact area, disperses the locking force, and reduces the risk of local wear. The ring-shaped locking is more vibration resistant than the traditional bolt connection and prevents the dustproof threaded tube 103 from loosening during the operation of the drive shaft.

[0052] Specifically, a sealing ring 103a is fixedly connected to the top of the dustproof threaded tube 103, and a sealing plate 103b is fixedly connected to one side of the inner cavity of the bushing 101. The bottom of the sealing plate 103b is in contact with the sealing ring 103a.

[0053] The contact surfaces of the sealing ring 103a and the sealing plate 103b form a double seal, which enhances the dustproof effect, prevents dust from entering the inner cavity of the bushing 101 from the snap-fit ​​gap, and extends the service life of the drive shaft.

[0054] When this technical solution is in operation, if it is necessary to disassemble the dustproof threaded tube 103, the operator turns the handle 205g, which drives the lead screw 205b to rotate. The movable block 205c on the surface of the lead screw 205b moves threadedly. The movable block 205c pushes the horizontal plate 205f to slide in the slide groove 205h through the movable rod 205d and the connecting rod 205e. This, in turn, drives the locking block 202 to move in the inner cavity of the embedded groove 201, causing the locking block 202 to disengage from the slot 203. At this time, the dustproof threaded tube 103 can be removed from the slot. Remove the bushing 101. During installation, align the top of the dustproof threaded tube 103 with the bushing 101, so that the slot 203 is aligned with the insert slot 201. Rotate the handle 205g in the opposite direction to reset the locking block 202 until the locking block 202 is engaged in the slot 203 to complete the installation. Throughout the process, the limit buckle 206a slides on the limit rod 206b to limit the range of movement of the horizontal plate 205f and ensure operational safety. The sealing ring 103a contacts the sealing plate 103b to ensure the sealing of the connection.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
