Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an adjusting screw with a positioning pin hole. Background Technology
[0002] The locating pin hole is a key part of the adjusting screw. By setting the locating pin hole on the screw body, it can cooperate with the corresponding locating pin to achieve precise positioning of the screw during the adjustment process, effectively avoiding the impact on assembly accuracy or equipment performance caused by shaking or offset during adjustment.
[0003] However, existing adjusting screws with locating pin holes have certain limitations in practical use. When faced with thickness deviations in parts produced in different batches, existing adjusting screws are often difficult to flexibly adapt to parts produced in different batches, reducing the applicability of the tool. This leads to increased debugging difficulty in the assembly process due to insufficient adjustment accuracy, and reduced work efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an adjusting screw with a locating pin hole, which aims to improve the problem that traditional adjusting screws with locating pin holes are difficult to flexibly adapt to parts produced in different batches and reduce the applicability of the tool.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An adjusting screw with a locating pin hole includes a screw rod, a hexagonal hole at the top of the screw rod, a nut slidably connected to the outside of the screw rod, a washer fixedly connected to the outside of the nut, the inside of the washer slidably connected to the outside of the screw rod, a bolt threadedly connected to the outside of the screw rod, a locating hole at one end of the screw rod, a first sliding rod slidably connected inside the locating hole, the bolt being disposed outside the first sliding rod, and an adjusting component being disposed outside the nut.
[0007] Preferably, the adjustment assembly includes a control plate, which is disposed outside the nut. A retaining plate is fixedly connected to the outside of the control plate. One end of the retaining plate is engaged with a limit groove, and a second spring is disposed inside the retaining plate.
[0008] Preferably, one end of the second spring is disposed inside the nut, and the limiting groove is formed on the outside of the screw.
[0009] Preferably, a control rod is provided at the bottom end of the screw, and a second slide rod is fixedly connected to the top end of the control rod.
[0010] Preferably, the outer side of the second slide rod is slidably connected to the inside of the screw rod, and a locking rod is fixedly connected to the top end of the second slide rod.
[0011] Preferably, the external part of the locking rod is slidably connected to the inside of the screw, and a first spring is provided on the lower surface of the locking rod.
[0012] Preferably, one end of the first spring is disposed inside the screw, and a slide rail is fixedly connected inside the positioning hole.
[0013] Preferably, the slide rail is slidably connected to the outside of the first slide rod.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by pushing the nut to drive the clamping plate to slide, the clamping plate pushes the second spring to retract. When the clamping plate slides to a certain position, the second spring releases its elastic force to push the clamping plate into the limiting groove, fixing the nut to the outside of the screw, thereby flexibly responding to the thickness deviation of different batches of parts and achieving the effect of improving the applicability of the screw.
[0016] 2. In this utility model, by pulling the control lever, the second slide bar is driven to slide downward, the second slide bar drives the locking rod to slide, and the locking rod pushes the first spring to retract, thereby causing the locking rod to leave the groove in the first slide bar. Thus, the installation or disassembly operation can be completed without the need for tools, thereby reducing the operator's dependence on tools and shortening the operation time.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an adjusting screw with a positioning pin hole, including a screw rod 1, a hexagonal hole 2 at the top of the screw rod 1, a nut 3 slidably connected to the outside of the screw rod 1, a washer 5 fixedly connected to the outside of the nut 3, a washer 5 slidably connected to the inside of the washer 5 on the outside of the screw rod 1, a bolt 6 threadedly connected to the outside of the screw rod 1, a positioning hole 7 at one end of the screw rod 1, a first slide rod 8 slidably connected to the inside of the positioning hole 7, the bolt 6 being disposed outside the first slide rod 8, and an adjusting component 4 being disposed outside the nut 3;
[0026] Specifically, the screw 1 consists of a connecting rod and a threaded connecting rod to provide a sliding track for the nut 3. The hexagonal hole 2 is used to screw the screw 1 into the part using a tool. The nut 3 is used to fit the part to prevent the screw 1 from loosening. The washer 5 is used to prevent the nut 3 from rotating and scratching the part. The bolt 6 is used to cooperate with the nut 3 to fix the part. The positioning hole 7 and the first sliding rod 8 are used to prevent the bolt 6 from loosening due to vibration. The adjusting component 4 is used to adjust the nut 3, thereby reducing the dependence on the screw size accuracy and achieving the effect of simplifying the assembly process.
[0027] Reference Figure 3 and Figure 4 The adjustment assembly 4 includes a control plate 401, which is located outside the nut 3. A retaining plate 402 is fixedly connected to the outside of the control plate 401. One end of the retaining plate 402 is engaged with a limiting groove 403. A second spring 404 is located inside the retaining plate 402. One end of the second spring 404 is located inside the nut 3. The limiting groove 403 is located outside the screw 1.
[0028] Specifically, the control plate 401 is an arc-shaped connecting plate used to control the upward reset of the clamping plate 402. The clamping plate 402 is a concave connecting plate used to fix the nut 3 to the outside of the screw 1. The limiting groove 403 is used to provide a groove for the clamping plate 402. The second spring 404 is a compression spring used to provide pressure to the clamping plate 402 so that the clamping plate 402 is locked in the limiting groove 403. Thus, with slight adjustments according to the thickness of the new part, the installation can be completed quickly, achieving the effect of shortening maintenance time and reducing maintenance costs.
[0029] Reference Figure 5 A control rod 9 is provided at the bottom end of the screw 1, and a second slide rod 10 is fixedly connected to the top end of the control rod 9. The second slide rod 10 is slidably connected to the outside of the screw 1, and a locking rod 12 is fixedly connected to the top end of the second slide rod 10. The locking rod 12 is slidably connected to the outside of the screw 1, and a first spring 11 is provided on the lower surface of the locking rod 12. One end of the first spring 11 is located inside the screw 1, and a slide rail 13 is fixedly connected to the inside of the positioning hole 7. The slide rail 13 is slidably connected to the outside of the first slide rod 8.
[0030] Specifically, the outer wall of the first slide rod 8 has a groove that fits tightly with the slide rail 13 for quick positioning of the first slide rod 8. The outer wall of the first slide rod 8 has a groove that fits with the locking rod 12 for fixing the first slide rod 8. The outer wall of the control rod 9 has a groove for the user to pinch the control rod 9 and pull the second slide rod 10. The second slide rod 10 is used to connect the control rod 9 and the locking rod 12. The locking rod 12 is used to lock the first slide rod 8. The first spring 11 is used to provide pressure to the locking rod 12 and to reset the locking rod 12 after the first slide rod 8 is removed, thereby improving the versatility and adaptability of the structure.
[0031] Working principle: When the position of nut 3 needs to be adjusted according to the thickness of the part, push nut 3 to slide downwards, thereby causing nut 3 to drive the retaining plate 402 to slide within nut 3. Then, retaining plate 402 pushes the second spring 404 to retract. After retaining plate 402 slides to the appropriate position, the second spring 404 releases its elastic force and pushes retaining plate 402 into the limiting groove 403 in screw 1, thereby fixing nut 3 to the outside of screw 1 after sliding. This allows for flexible handling of thickness deviations in different batches of parts, thereby improving the applicability of the screw.
[0032] Next, insert the first slide rod 8 into the positioning hole 7 inside the screw 1, so that one end of the first slide rod 8 pushes the locking rod 12 to slide inside the screw 1. Then, the locking rod 12 pushes the second slide rod 10 to slide. Furthermore, the locking rod 12 pushes the first spring 11 to retract. When the groove outside the first slide rod 8 slides to the outside of the locking rod 12, the first spring 11 releases its elastic force to push the locking rod 12 into the groove outside the first slide rod 8. Thus, the installation or disassembly operation can be completed without the need for tools, thereby reducing the operator's dependence on tools and shortening the operation time.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
