Description

Technical Field

[0001] This utility model relates to the field of transmission component fastening technology, specifically to an anti-loosening component and a transmission assembly. Background Technology

[0002] In some transmission structures, in order to facilitate the replacement and maintenance of vulnerable parts, they are usually designed as separate units, with gears or transmission wheels detachably mounted on the shaft. However, in such transmission components, as the shaft rotates continuously, the bolts and other locking parts used to connect and fasten the shaft and the transmission components are prone to falling off. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an anti-loosening component that can reduce the phenomenon of locking components on transmission parts falling off.

[0004] This utility model also proposes a transmission assembly having the above-mentioned anti-loosening component.

[0005] According to a first aspect of the present invention, an anti-loosening component is used to prevent a locking member on a transmission component from falling off, comprising a first anti-loosening part and a second anti-loosening part. The first anti-loosening part includes a first side surface, which has a recessed receiving space for accommodating the transmission component. The second anti-loosening part is connected to the first side surface and extends toward the center of the receiving space relative to the first side surface, and the second anti-loosening part can be inserted into the locking member.

[0006] The anti-loosening component according to the present invention has at least the following beneficial effects: In related technologies, locking components usually pass radially through the transmission component and the rotating shaft. During the frequent operation of the transmission component, the locking component may become loose. Since the locking component uses a screw structure with a blind hole on the back to facilitate removal and reduce space occupation, the blind hole is used to insert a corresponding shaped hex wrench or other wrench. Therefore, the anti-loosening component of this application is provided with two different types of anti-loosening parts. The first anti-loosening part is sleeved on the outer periphery of the transmission component, and the second anti-loosening part is directly inserted into the blind hole on the back of the locking component. The combination of the two can fix the locking component inside the transmission component and prevent the locking component from coming out of the transmission component as the usage time increases.

[0007] According to some embodiments of this utility model, the first anti-loosening part is provided with an opening, the opening being connected to the receiving space, and the transmission component can enter the receiving space through the opening. Providing an opening makes it easier to install the anti-loosening component on the transmission assembly; simply slip the anti-loosening component onto the transmission component from top to bottom, allowing the transmission component to enter the receiving space.

[0008] According to some embodiments of this utility model, the opening includes a first wall and a second wall disposed opposite to each other, extending from the center of the receiving space toward the edge of the receiving space, with the distance between the first wall and the second wall gradually increasing. The opening has a shape that opens from the inside out, making it easier for the transmission component to enter the receiving space from the opening and achieve locking.

[0009] According to some embodiments of this utility model, the second anti-detachment part is configured such that: the second anti-detachment part extends in a straight line, and the central axis of the second anti-detachment part coincides with the axis of symmetry of the opening. The straight-line second anti-detachment part can be better inserted into the locking member, fitting well with most vertically opened operating ports. The coincidence of the central axis of the second anti-detachment part with the axis of symmetry of the opening allows the transmission member to slide along the sliding direction after entering the receiving space from the opening, enabling the second anti-detachment part to be inserted into the operating port on the back of the locking member, reducing operational difficulty, and ensuring that the extension direction of the second anti-detachment part, the relative movement direction of the transmission member and the anti-loosening member, and the extension direction of the operating port are all on the same straight line.

[0010] According to some embodiments of this utility model, the first anti-detachment part includes an arc segment, the opening is formed in the arc segment, and the inner wall surface of the arc segment is the first side surface. Most transmission components usually have a circular outer circumferential surface for easy installation. The arc-shaped first anti-detachment part can accommodate most transmission components, and the fitting process between the arcs is also smoother.

[0011] According to some embodiments of this utility model, the first anti-detachment part is elastic, and the size of the opening is smaller than the maximum inner diameter of the first anti-detachment part. This allows the first anti-detachment part to deform as the transmission component enters through the opening, and after the transmission component enters the receiving space, the rebound force of the first anti-detachment part enables it to be better fixed to the outer periphery of the transmission component, improving the anti-loosening effect.

[0012] According to some embodiments of this utility model, the second anti-detachment part is configured such that: the second anti-detachment part extends along a straight line, and the outer peripheral cross-section of the second anti-detachment part is an equilateral hexagon. The equilateral hexagonal design allows the second anti-detachment part to adapt to locking members with internal hexagonal threaded holes on the back, and the equilateral hexagonal structure is not prone to slippage or rotation after being inserted into the operating port on the back of the locking member.

[0013] According to some embodiments of the present invention, the material of the first anti-detachment part is polypropylene, and / or the material of the second anti-detachment part is polyetheretherketone.

[0014] The transmission assembly according to a second aspect embodiment of the present invention includes the anti-loosening component as described in any one of the first aspect embodiments, and further includes a transmission component and a locking component. The transmission component is disposed in the receiving space, the locking component is connected to the transmission component, and an operating port is provided at one end of the locking component near the first side, with the second anti-loosening part inserted into the operating port.

[0015] The transmission assembly according to the embodiments of this utility model has at least the following beneficial effects: In related technologies, locking members are usually radially inserted through the transmission member and the shaft. During the frequent operation of the transmission member, the locking member may become loose. In order to facilitate removal and reduce space occupation, the locking member uses a screw structure with a blind hole on the back. The blind hole is used to insert a corresponding shaped hex wrench or other wrench. Therefore, the anti-loosening member of this application is provided with two different types of anti-loosening parts. The first anti-loosening part is sleeved on the outer periphery of the transmission member, and the second anti-loosening part is directly inserted into the blind hole on the back of the locking member. The combination of the two can fix the locking member inside the transmission member and prevent the locking member from coming out of the transmission member as the usage time increases. The transmission assembly using the anti-loosening member can reduce transmission failures caused by the locking member falling off and improve transmission efficiency.

[0016] According to some embodiments of the present invention, the transmission component has a through hole along the axial direction, through which a rotating shaft can pass. The transmission component includes a main body and a gear part coaxially arranged with the through hole. The locking component can pass through the main body and the rotating shaft to fix the main body and the rotating shaft together.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] refer to Figures 1 to 4According to a first aspect embodiment of the present invention, an anti-loosening member 100 is used to prevent the locking member 202 on the transmission member 201 from falling off, and includes a first anti-loosening part 101 and a second anti-loosening part 104. The first anti-loosening part 101 includes a first side surface 102, and the first side surface 102 is recessed with a receiving space 103 for accommodating the transmission member 201. The second anti-loosening part 104 is connected to the first side surface 102, and the second anti-loosening part 104 extends toward the center of the receiving space 103 relative to the first side surface 102. The second anti-loosening part 104 can be inserted into the locking member 202. In related technologies, the locking member 202 typically passes radially through the transmission member 201 and the shaft. During frequent operation of the transmission member 201, the locking member 202 may become loose. To facilitate removal and reduce space occupation, the locking member 202 uses a screw structure with a blind hole on its back. The blind hole is used to insert a corresponding shaped Allen wrench or other wrench. Therefore, the anti-loosening member 100 of this application is provided with two different types of anti-loosening parts. The first anti-loosening part 101 is sleeved on the outer periphery of the transmission member 201, and the second anti-loosening part 104 is directly inserted into the blind hole on the back of the locking member 202. The combination of the two can fix the locking member 202 inside the transmission member 201 and prevent the locking member 202 from coming out of the transmission member 201 as the usage time increases.

[0026] It should be noted that the reference Figure 3 and Figure 4 In some embodiments of this utility model, the transmission component 201 may be a gear structure with a rotating shaft, or it may be a belt or a rolling wheel structure, while the locking component 202 is a screw with a blind hole on the back. The anti-loosening component 100 of this application embodiment uses the blind hole to fasten the locking component 202. When it is necessary to disassemble the locking component 202, the anti-loosening component 100 of this application is first taken out, and then an Allen wrench or spline wrench or other parts are inserted into the blind hole of the locking component 202 for disassembly, so that the transmission component 201 can be disengaged from the rotating shaft.

[0027] It should be noted that the aforementioned blind hole is... Figure 3 and Figure 4 The operation port 203 shown in the figure is used to allow the operating wrench to be inserted into the locking member 202 to tighten or loosen it, and to allow the second anti-detachment part 104 to be inserted therein to achieve the anti-detachment function when the transmission member 201 does not need to be replaced.

[0028] refer to Figure 1In some embodiments of this utility model, the first anti-loosening part 101 is provided with an opening 105, which connects to the receiving space 103. The transmission member 201 can enter the receiving space 103 through the opening 105. Providing an opening 105 makes it easier to install the anti-loosening part 100 on the transmission assembly 200. Simply put the anti-loosening part 100 on the transmission member 201 from top to bottom, so that the transmission member 201 enters the receiving space 103.

[0029] It should be noted that in some embodiments of this utility model, the first anti-detachment part 101 can also be made into a detachable closed-loop structure, so as to be fitted onto the transmission member 201, allowing the second anti-detachment part 104 to be inserted into the locking member 202, and after the second anti-detachment part 104 is inserted, it can also prevent the first anti-detachment part 101 from rotating around its own axis.

[0030] refer to Figure 1 In some embodiments of this utility model, the opening 105 includes a first wall 106 and a second wall 107 disposed opposite to each other, extending from the center of the receiving space 103 towards the edge of the receiving space 103, with the distance between the first wall 106 and the second wall 107 gradually increasing. This design makes the opening 105 open from the inside out, making it easier for the transmission member 201 to enter the receiving space 103 from the opening 105 and lock. Furthermore, in some embodiments of this utility model, the connection positions of the first wall 106 and the first side surface 102, and the connection positions of the second wall 107 and the first side surface 102, can be chamfered to make the process of the transmission member 201 entering the receiving space 103 smoother. Furthermore, in some embodiments of this utility model, the first side surface 102 can be provided with an anti-slip layer or a non-slip pad can be directly added to prevent the first anti-detachment part 101 from sliding when it is installed on the transmission member 201, thereby improving structural stability.

[0031] refer to Figure 1 In some embodiments of this invention, the second anti-detachment portion 104 is configured such that it extends in a straight line, and its central axis coincides with the axis of symmetry of the opening 105. This linear second anti-detachment portion 104 allows for better insertion. Figure 3 and Figure 4 The operation port 203 shown is consistent with most vertically opened operation ports 203. The central axis of the second anti-detachment part 104 coincides with the symmetrical axis of the opening 105 so that after the transmission member 201 enters the receiving space 103 from the opening 105, the second anti-detachment part 104 can be inserted into the operation port 203 on the back of the locking member 202 along the sliding direction, reducing the difficulty of operation and making the extension direction of the second anti-detachment part 104, the relative movement direction of the transmission member 201 and the anti-loosening member 100, and the extension direction of the operation port 203 on the same straight line.

[0032] refer to Figure 1 In some embodiments of this utility model, the first anti-detachment part 101 includes an arc segment 108, an opening 105 is formed in the arc segment 108, and the inner wall surface of the arc segment 108 is the first side surface 102. Most transmission components 201 usually have a circular outer peripheral surface for easy installation. The arc-shaped first anti-detachment part 101 can accommodate most transmission components 201, and the fitting process between the arcs is also smoother.

[0033] refer to Figure 1 In some embodiments of this utility model, the first anti-detachment part 101 is elastic, and the size of the opening 105 is smaller than the maximum inner diameter of the first anti-detachment part 101. This design allows the first anti-detachment part 101 to deform during the process of the transmission member 201 entering through the opening 105. After the transmission member 201 enters the receiving space 103, the rebound force of the first anti-detachment part 101 enables it to be better fixed to the outer periphery of the transmission member 201, thereby improving the anti-loosening effect.

[0034] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the second anti-detachment part 104 is configured such that: the second anti-detachment part 104 extends along a straight line, and the outer peripheral cross-section of the second anti-detachment part 104 is an equilateral hexagon. The equilateral hexagonal design allows the second anti-detachment part 104 to adapt to the locking member 202 with an internal hexagonal threaded hole on the back, and the equilateral hexagonal structure is not prone to sliding or rotating after being inserted into the operating port 203 on the back of the locking member 202.

[0035] In some embodiments of this utility model, the first anti-detachment part 101 is made of polypropylene, and / or the second anti-detachment part 104 is made of polyetheretherketone (PEEK). Polypropylene has a low density, and the first anti-detachment part 101 is a major component of the anti-loosening part 100. Therefore, using polypropylene makes the overall structure lighter. Polypropylene also has good heat resistance, allowing the anti-loosening part 100 to be used in transmission components 200 in high-temperature environments without easily deforming or melting. The good bending fatigue resistance of polypropylene also allows it to be repeatedly installed and disassembled after the opening 105 is provided without easily causing permanent deformation, resulting in a longer service life. In some embodiments, the first anti-detachment part 101 can also be made of materials such as polyethylene or polyvinyl chloride. Polyetheretherketone (PEEK) possesses excellent mechanical strength and stability, making it resistant to deformation after the second anti-loosening part 104 is inserted into the locking member 202. Furthermore, PEEK exhibits good high-temperature resistance and chemical stability, allowing the anti-loosening part 100 to be applied in a wider range of transmission component 200 usage scenarios, thus enhancing its adaptability. PEEK also demonstrates good dimensional stability, enabling it to better fit the operating port 203 of the locking member 202 when used to manufacture the relatively small second anti-loosening part 104 with higher dimensional accuracy requirements. In some embodiments, polyethylene, alloys, or other materials can also be used to manufacture the second anti-loosening part 104.

[0036] refer to Figure 3 and Figure 4 According to a second aspect embodiment of the present invention, the transmission assembly 200 includes the anti-loosening member 100 of any one of the first aspect embodiments, and further includes a transmission member 201 and a locking member 202. The transmission member 201 is disposed in the receiving space 103, the locking member 202 is connected to the transmission member 201, and an operating port 203 is provided at one end of the locking member 202 near the first side 102, and a second anti-loosening part 104 is inserted into the operating port 203. In related technologies, the locking element 202 typically passes radially through the transmission element 201 and the shaft. During frequent operation of the transmission element 201, the locking element 202 may become loose. To facilitate removal and reduce space occupation, the locking element 202 uses a screw structure with a blind hole on its back. The blind hole is used to insert a corresponding shaped Allen wrench or other wrench. Therefore, the anti-loosening element 100 of this application is provided with two different types of anti-loosening parts. The first anti-loosening part 101 is sleeved on the outer periphery of the transmission element 201, and the second anti-loosening part 104 is directly inserted into the blind hole on the back of the locking element 202. The combination of the two can fix the locking element 202 inside the transmission element 201, preventing the locking element 202 from coming out of the transmission element 201 over time. The transmission assembly 200 using the anti-loosening element 100 can reduce transmission failures caused by the locking element 202 falling off and improve transmission efficiency.

[0037] It should be noted that, specifically, in some embodiments of this utility model, the transmission component 200 is applied in the field of PCB board manufacturing transmission. Since circuit boards require long-term manufacturing and transportation, the transmission component 200 has a long service life. Furthermore, circuit boards have high surface quality requirements. If the transmission component 201 on the transmission component 200 malfunctions, for example, if the locking component 202 falls off, causing the transmission component 201 to be unable to rotate smoothly around the axis or to fall off directly, it may scratch the surface of the circuit board, causing quality problems. Using the transmission component 200 of this application embodiment can effectively reduce the panel scratch rate caused by the locking component 202 falling off, thus improving the manufacturing quality of the circuit board.

[0038] refer to Figure 3 and Figure 4 In some embodiments of this utility model, the transmission component 201 has a through hole 206 along the axial direction, through which a rotating shaft can pass. The transmission component 201 includes a main body portion 204 and a gear portion 205 coaxially arranged with the through hole 206. The locking component 202 can pass through the main body portion 204 and the rotating shaft to fix the main body portion 204 to the rotating shaft. Gear transmission has a stable transmission ratio, wide application scenarios, can adapt to most transmission environments, and has a long service life. Therefore, the transmission component 200 as a whole can also have a longer service life and better adapt to long-term transmission scenarios.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
