Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a combined locking device. Background Technology

[0002] In many electromechanical and electronic products, certain electrical parameters need to be adjusted. After adjustment to the appropriate position, another mechanism is needed to fix the adjusted parameters. Generally, the adjustment mechanism is a screw, and the fastening mechanism is a nut.

[0003] The electrical parameters that need to be adjusted are often quite precise. If separate tools are used, and the parameters are adjusted and then another tool is used to tighten the fixing nut, the adjusted parameters will become misaligned. Therefore, a combination tool is needed that can tighten the fixing nut promptly after the electrical parameters are adjusted to the appropriate position without changing tools, so as to maintain the correct electrical parameters. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a combined locking device that can solve the problems in the prior art.

[0005] The technical solution of the present invention is a combined locking device, comprising an outer sleeve, an actuator, a handle, and a tightening unit. The actuator includes a positioning sleeve and an adjusting unit. The adjusting unit slides up and down along the axis within the positioning sleeve and is used to adjust the screw to be adjusted. The positioning sleeve is used to lock the fixing nut that mates with the screw to be adjusted. The handle is fixedly connected to the adjusting unit via the tightening unit and provides resistance when adjusting the screw. The outer sleeve is fixedly connected to the positioning sleeve via its own threads and provides assistance when tightening the fixing nut. When adjusting the screw, the positioning sleeve is fitted onto the fixing nut, and the adjusting unit slides upward and extends out of the positioning sleeve, adjusting the screw to be adjusted to complete the adjustment function. When tightening the fixing nut, the adjusting unit slides downward and retracts into the positioning sleeve, completing the locking function via the positioning sleeve fitted onto the fixing nut.

[0006] Preferably, the device further includes a pressure ring, which is fixedly connected to the positioning sleeve by an interference fit, and the pressure ring is fixedly connected to the adjustment unit by an interference fit.

[0007] Preferably, the top of the adjusting unit is provided with a wedge-shaped flat opening for adjusting the screw to be adjusted, and the top of the positioning sleeve is provided with a hexagonal sleeve for locking the fixing nut.

[0008] Preferably, the outer casing is a cylindrical part with knurled outer cylindrical surface and internal thread on inner cylindrical surface.

[0009] Preferably, the outer surface of the positioning sleeve is a stepped shaft structure, and the inner surface is provided with stepped holes. The external thread on the stepped shaft is connected to the internal thread on the outer sleeve, and the stepped shaft is provided with an axial limiting shoulder. After the outer sleeve is connected to the positioning sleeve 2, axial positioning is achieved. The stepped holes are used to install the adjustment unit and the pressure ring, respectively.

[0010] Preferably, the adjustment unit is an adjustment lever.

[0011] Preferably, the adjusting rod has a stepped shaft structure, with the intermediate shaft engaging with the stepped hole of the positioning sleeve to achieve up and down sliding, and the bottom part being milled flat and fixedly connected to the handle through a tightening unit.

[0012] Preferably, the setter unit is a set screw.

[0013] With the above technical solution, during the process of adjusting and locking electrical parameters, the positioning sleeve can be placed on the locking nut first, and then the adjusting unit can be extended to tighten the screw to be adjusted. After the electrical parameters are adjusted to the appropriate position, the adjusting unit can be retracted, and the positioning sleeve can be used to tighten the fixing nut directly to achieve integrated adjustment and locking operation, effectively preventing the "deviation" phenomenon caused by using separate tools.

[0019] Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details are set forth for purposes of explanation and not limitation, in order to aid in a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced in other embodiments departing from these specific details.

[0020] It should be noted that, in order to avoid obscuring the invention with unnecessary details, only the device structure and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0021] like Figure 1 and 2 As shown, this embodiment of the invention provides a combined locking device, which includes an outer sleeve 1, an actuator 2, a handle 5, and a locking unit 6. The actuator includes a positioning sleeve 2 and an adjusting unit 3. The adjusting unit 3 can slide up and down along the axis in the positioning sleeve 2 and is used to adjust the screw to be adjusted. The positioning sleeve 2 is used to lock the fixing nut that cooperates with the screw to be adjusted. The handle 5 is fixedly connected to the adjusting unit 3 through the locking unit 6 and is used to provide resistance when adjusting the screw to be adjusted. The outer sleeve 1 is fixedly connected to the positioning sleeve 2 through its own thread and is used to provide assistance when locking the fixing nut. When adjusting the screw to be adjusted, the positioning sleeve 2 (such as the top) is on the fixing nut, and the adjusting unit 3 slides upward and extends out of the positioning sleeve 2. The adjusting unit 3 is used to adjust the screw to be adjusted to complete the adjustment function. When locking the fixing nut, the adjusting unit 3 slides downward and retracts into the positioning sleeve 2. The locking function is completed by the positioning sleeve 2 on the fixing nut (that is, the positioning nut is already on the fixing nut when adjusting the screw to be adjusted).

[0022] With the above technical solution, during the process of adjusting and locking electrical parameters, the positioning sleeve can be placed on the locking nut first, and then the adjusting unit can be extended to tighten the screw to be adjusted. After the electrical parameters are adjusted to the appropriate position, the adjusting unit can be retracted, and the positioning sleeve can be used to tighten the fixing nut directly to achieve integrated adjustment and locking operation, effectively preventing the "deviation" phenomenon caused by using separate tools.

[0023] In other words, when the screw to be adjusted needs to be adjusted, the adjustment unit extends; when the screw is adjusted to the correct position and the nut needs to be tightened, the adjustment unit retracts. Thus, the adjustment and tightening actions are completed in one integrated unit without changing tools, preventing electrical parameter deviations caused by tool changes.

[0024] According to one embodiment of the present invention, the device further includes a pressure ring 4, which is fixedly connected to the positioning sleeve 2 by an interference fit, and the pressure ring 4 is fixedly connected to the adjustment unit 3 by an interference fit.

[0025] This restricts the axial sliding of the adjusting unit and prevents it from slipping out of the positioning sleeve when it slides within the sleeve.

[0026] According to one embodiment of the present invention, the top of the adjusting unit (the end of the adjusting unit that extends out of the sleeve) is provided with a wedge-shaped flat opening for adjusting the screw to be adjusted, and the top of the positioning sleeve (the end that the adjusting unit can extend out of) is provided with a hexagonal sleeve for locking the fixing nut.

[0027] According to one embodiment of the present invention, the outer sleeve is a cylindrical part, the outer cylindrical surface is provided with knurling to prevent slippage during use, and the inner cylindrical surface is provided with internal threads.

[0028] According to one embodiment of the present invention, the outer surface of the positioning sleeve is a stepped shaft structure, and the inner surface is provided with stepped holes. The external thread on the stepped shaft is connected to the internal thread on the outer sleeve, and the stepped shaft is provided with an axial limiting shoulder. After the outer sleeve is connected to the positioning sleeve 2, axial positioning is achieved. The stepped holes are used to install the adjustment unit and the pressure ring, respectively.

[0029] According to one embodiment of the present invention, the adjustment unit is an adjustment lever.

[0030] According to one embodiment of the present invention, the adjusting rod has a stepped shaft structure, with a wedge-shaped flat opening at the top for use when adjusting the screw, the intermediate shaft engaging with the stepped hole of the positioning sleeve to achieve up and down sliding, and a portion of the bottom being milled flat and fixedly connected to the handle through a tightening unit.

[0031] According to one embodiment of the present invention, the setter unit is a set screw.

[0032] The combined locking device of the present invention will now be described with reference to examples.

[0033] like Figure 1 and 2 As shown, a combination locking tool includes: an outer sleeve 1, a positioning sleeve 2, an adjusting rod 3, a pressure ring 4, a handle 5, and a set screw 6. The positioning sleeve 2 and the adjusting rod 3 are two actuators; the adjusting rod 3 is responsible for tightening the screw that adjusts electrical parameters, and the positioning sleeve 2 is responsible for locking the nut. The top of the adjusting rod 3 is designed with a wedge-shaped flat opening for tightening the screw to be adjusted, and the top of the positioning sleeve 2 is designed with a hexagonal sleeve for tightening the nut. The handle 5 is fixed to the adjusting rod 3 via the set screw 6, providing resistance when tightening the adjusting screw. The outer sleeve 1 is fixed to the positioning sleeve 2 via its own threads, providing assistance when tightening the nut. The adjusting rod 3 can slide up and down along its axis within the positioning sleeve 2. When tightening the adjusting screw, the adjusting rod 3 slides upward, causing the wedge-shaped flat opening to protrude from the hexagonal sleeve, completing the adjustment function. When tightening the nut, the adjusting rod 3 slides downward, causing the wedge-shaped flat opening to retract below the hexagonal sleeve, completing the locking function. The pressure ring 4 and the positioning sleeve 3 are fixed together by an interference fit to prevent the adjusting rod 3 from coming out of the positioning sleeve 2 when it slides in the positioning sleeve 2.

[0034] The outer sleeve 1 is a cylindrical part with knurled outer cylindrical surface to prevent slippage during use. The inner cylindrical surface has internal threads for connection with the positioning sleeve 2. The outer surface of the positioning sleeve 2 is a stepped shaft structure, with stepped holes on the inner surface and a hexagonal sleeve at the top for tightening the fixing nut. The stepped shaft has external threads that connect with the internal threads on the outer sleeve 1, and an axial limiting shoulder is designed to achieve axial positioning after the outer sleeve 1 is connected to the positioning sleeve 2. The internal stepped holes are used to install the adjusting rod 3 and the pressure ring 4. The adjusting rod 3 is a stepped shaft structure with a wedge-shaped flat opening at the top for adjusting the screw to be adjusted. The middle shaft mates with the stepped hole in the positioning sleeve 2 to allow for vertical sliding. A portion of the bottom is milled flat and fixed to the handle 5 with a set screw 6. The pressure ring 4 has an interference fit with the lower hole of the adjusting rod 3, which restricts the axial sliding of the adjusting rod 3 after installation, preventing it from dislodging.

[0035] As can be seen from the above embodiments, the combined locking device of the present invention has the following advantages:

[0036] After adjusting the electrical parameters of electromechanical and electronic products to the appropriate position, the adjusting device can promptly tighten the fixing nut without leaving the screw to be adjusted, thereby preventing the electrical parameters from "going astray".
