Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a detachable clamp for adjusting the length of a ceramic push rod. Background Technology

[0002] A clamp is a special device used to fix, position and clamp workpieces during machining, assembly or inspection. Its core function is to ensure that the workpiece maintains the correct position and posture during machining or assembly, thereby improving accuracy, efficiency and safety. Its main components are clamping body, clamping mechanism, auxiliary devices and connecting elements.

[0003] Existing technologies, such as the utility model with publication number CN215107371U, disclose an adjustable-length profile clamp. This utility model is an adjustable-length profile clamp including a first slide groove and a second slide groove. A locking bolt passes through both the first and second mounting plates. The screw end of the locking bolt passes through the first and second mounting plates and is threaded with a fixing nut. Vertical connecting plates are connected to the top surfaces of the two side walls of the second slide groove, facing the second mounting plate. Locking blocks for engaging the profile grooves are connected to the opposite sides of the second and first connecting plates. This utility model allows for precise adjustment of the fixed width of the profile clamp; a full rotation of the locking bolt increases or decreases the fixed width by one thread pitch. Furthermore, the locking blocks can engage with the grooves of the profiles, clamping two adjacent profiles together and then locking them in place with the locking bolt and fixing nut. This provides good profile fixation, reducing the gap between spliced ​​templates and improving casting quality.

[0004] The following defects were found in the above-mentioned issues: In the existing technology of push rod length adjustment clamps, clamps are usually used to hold the push rods and then adjust their length. However, during operation, many push rods of different diameters need to be clamped. In the existing push rod clamps, different clamps of different specifications need to be changed to hold push rods of different diameters. This leads to a significant increase in labor costs and a reduction in work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing push rod clamps, which require constantly changing clamps of different specifications to hold push rods of different diameters, resulting in significantly increased labor costs and reduced work efficiency. Therefore, this invention proposes a detachable clamp for adjusting the length of ceramic push rods.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a detachable clamp for adjusting the length of a ceramic push rod, comprising a push rod body, an extension rod, and a base. The push rod body is slidably connected to the extension rod. A clamping device is provided on the upper surface of the base. The clamping device includes a rectangular groove, which is formed on the upper surface of the base. A slider is slidably connected to the inner wall of the rectangular groove. A bearing plate is fixedly connected to the upper surface of the slider. Two connecting plates are fixedly connected to both sides of the base. A first screw is rotatably connected to the inner wall of the rectangular groove. The first screw is threadedly connected to the slider. A nut is fixedly connected to one end of the first screw. A first semi-circular buckle is fixedly connected to the upper surface of one of the connecting plates and the bearing plate. Two second screws are rotatably connected to one side of the first semi-circular buckle. A second semi-circular buckle is provided above the first semi-circular buckle. The second semi-circular buckle is threadedly connected to the second screw. A knob is fixedly connected to the end of the second screw away from the first semi-circular buckle. Two sliding rods are fixedly connected to the ends of the two connecting plates that are close to each other. The two sliding rods are slidably connected to the bearing plate.

[0007] The effect achieved by the above components is as follows: when the length of the push rod needs to be adjusted, the push rod and the extension rod are clamped and fixed by the first semicircular buckle and the second semicircular buckle. Then, the required extension length of the push rod can be adjusted by rotating the first screw. The first semicircular buckle and the second semicircular buckle are clamped together by the second screw, which can accommodate push rods of different diameters.

[0008] Preferably, the knob has four semi-circular grooves on its arc surface, and the four semi-circular grooves are evenly distributed on the arc surface.

[0009] The effect achieved by the above components is that when the second screw is turned by the knob, the operator can put their fingers into the semi-circular groove to turn the knob, making the operation simpler and easier to apply force.

[0010] Preferably, three handles are fixedly connected to the side of the nut, and the ends of the three handles away from the nut are all semi-circular.

[0011] The effect achieved by the above components is that when it is necessary to rotate the first screw, the three levers on the nut can be used to rotate it, which makes the operation more convenient and labor-saving.

[0012] Preferably, the inner walls of both the first and second semicircular buckles are provided with a plurality of anti-slip textures, and the plurality of anti-slip textures are evenly distributed on the inner walls of the first semicircular buckle and the second semicircular buckle.

[0013] The effect achieved by the above components is that when clamping the push rod and the extension rod, the anti-slip texture can increase the friction between the push rod and the first and second semicircular buckles, resulting in a better clamping effect.

[0014] Preferably, the base has four fixing devices on both sides, each of the four fixing devices including a rectangular plate. Rectangular blocks are fixedly connected to both sides of the rectangular plate. A rotating rod is rotatably connected to one end of two rectangular blocks that are close to each other. A ring is fixedly connected to the arc surface of the rotating rod. A first clamping plate is fixedly connected to the arc surface of the ring. A sliding plate is slidably connected to one side of the first clamping plate. The sliding plate completely penetrates the first clamping plate. A second clamping plate is fixedly connected to the lower surface of the sliding plate. A third screw is rotatably connected to the upper surface of the second clamping plate. The third screw is threadedly connected to the first clamping plate.

[0015] The effect achieved by the above components is that when the base is placed on the workbench or other relatively smooth surface, the first clamp and the second clamp can be used to move the second clamp toward the first clamp by rotating the third screw, thereby clamping the entire clamp on the platform according to the thickness of the platform, thus achieving the effect of fixing the entire clamp.

[0016] Preferably, a plurality of rubber strips are fixedly connected to the upper surface of the second clamping plate, and the plurality of rubber strips are evenly distributed on the second clamping plate.

[0017] The effect achieved by the above components is that when the clamp is held on the platform by the first clamp and the second clamp, the friction between the clamp and the platform can be increased by the several rubber strips on the second clamp, so as to make the fixing effect better.

[0018] Preferably, a plurality of suction cups are fixedly connected to the lower surface of the base, and the plurality of suction cups are evenly distributed on the lower surface of the base.

[0019] The effect achieved by the above components is that when the clamp is placed on the platform, it can be attached to the platform by the suction cup under the base, which further enhances the fixing effect of the device.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, when the length of the push rod needs to be adjusted, a corresponding clamp is required to hold and fix the push rod, thus enabling successful length adjustment. However, since the diameter of the push rod varies, it is necessary to constantly change the corresponding clamp when dealing with push rods of different diameters. By setting up a clamping device, push rods of different diameters can be clamped using the first and second semicircular buckles without the need to change clamps, thereby reducing usage costs and increasing work efficiency. The specific operating steps of the clamping device are as follows: When the push rod needs to be adjusted in length, it needs to be placed on the arc surface of the two first semicircular buckles. After placement, the four second screws located on the two second semicircular buckles can be rotated. When rotating the second screws, a knob on one end of the second screw can be used for rotation. The four semicircular grooves on the arc surface of the knob allow the operator to insert their fingers into the semicircular grooves to rotate the knob, making it easier for the operator to apply force. When the second screws are rotated, they will drive the second semicircular buckles to move towards the first semicircular buckles, thereby clamping and fixing the push rod. After clamping, the first and second semicircular buckles connected to the support plate can slide along the rectangular groove by rotating the first screw located in the rectangular groove. At the same time, the support plate will also slide in the same direction along the slide bar, thereby increasing the transmission efficiency of the support plate. Rotating the first screw using the three grips on the side of the nut makes the operation of rotating the first screw simpler and more convenient. The several anti-slip textures located on the inner side of the first and second semicircular buckles can increase the friction between the semicircular buckles and the push rod, thereby increasing the clamping effect.

[0022] In this invention, a fixing device is installed. When the clamp is needed to adjust the length of the push rod, it must be placed on a table or platform. However, after placement, the clamp may fall off the platform and be damaged due to severe vibration or accidental collision. The fixing device, using first and second clamps located on both sides of the base, secures the clamp to the platform, preventing it from falling. The specific operating steps of the fixing device are as follows: When the push rod length needs to be adjusted using the clamp, it needs to be placed on the workbench and fixed. After the clamp is placed on the workbench, the operator can rotate the four rotating rods located on both sides of the base. The four rotating rods are connected to the base via rectangular plates and blocks. When the rotating rods are rotated, the rings connected to them rotate at the same angle. When the rings rotate, the first clamp and the second clamp connected to the first clamp via a third screw and a sliding plate also rotate with the ring. When the second clamp rotates to a state relatively parallel to the bottom surface of the workbench, the rotation of the rotating rods and rings can be stopped. At this point, the third screw can be rotated. As the third screw rotates, it will cause the second clamping plate to slide upward inside the first clamping plate using the sliding plate. This will move the second clamping plate towards the first clamping plate. Then, depending on the thickness of the worktable, when the second clamping plate rises to make full contact with the bottom surface of the worktable, it will work together with the first clamping plate to fix the base to the worktable by pressing it. This completes the fixing of the clamp. The suction cups located under the base can adhere to the worktable when the base is placed, making the fixing effect of the device more stable. The rubber strips located on the second clamping plate can increase the friction between the second clamping plate and the bottom surface of the worktable when the second clamping plate contacts the bottom surface of the worktable, resulting in a better fixing effect.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a detachable clamp for adjusting the length of a ceramic push rod, including a push rod body 1, an extension rod 2 and a base 3. The push rod body 1 and the extension rod 2 are slidably connected. The upper surface of the base 3 is provided with a clamping device 4, and four fixing devices 5 are provided on both sides of the base 3.

[0029] The specific setup and function of the clamping device 4 and the fixing device 5 will be explained in detail below.

[0030] Reference Figure 2As shown, in this embodiment: the clamping device 4 includes a rectangular groove 401, which is formed on the upper surface of the base 3. A slider 402 is slidably connected to the inner wall of the rectangular groove 401. A bearing plate 403 is fixedly connected to the upper surface of the slider 402. Two connecting plates 404 are fixedly connected to both sides of the base 3. A first screw 405 is rotatably connected to the inner wall of the rectangular groove 401. The first screw 405 is threadedly connected to the slider 402. A nut 412 is fixedly connected to one end of the first screw 405. One of the connecting plates 404... Both the first semi-circular buckle 406 and the upper surface of the support plate 403 are fixedly connected to a first semi-circular buckle 406. Two second screws 408 are rotatably connected to one side of the first semi-circular buckle 406. A second semi-circular buckle 407 is provided above the first semi-circular buckle 406. The second semi-circular buckle 407 is threadedly connected to the second screws 408. A knob 409 is fixedly connected to the end of the second screws 408 away from the first semi-circular buckle 406. Two sliding rods 414 are fixedly connected to the ends of the two connecting plates 404 that are close to each other. The two sliding rods 414 are slidably connected to the support plate 403. When the push rod needs to be adjusted in length, the push rod and the extension rod 2 are clamped and fixed by the first semi-circular buckle 406 and the second semi-circular buckle 407. Then, the required extension length of the push rod can be adjusted by rotating the first screw 405. The first semi-circular buckle 406 and the second semi-circular buckle 407 are clamped together by the second screw 408, which can accommodate push rods of different diameters. The knob 409 has four semi-circular grooves 410 evenly distributed on its arc surface. When rotating the second screw 408 via the knob 409, the operator can insert their fingers into the semi-circular grooves 410 to rotate the knob 409, making operation simpler and easier to apply force. Three handles 413 are fixedly connected to the side of the nut 412, with each handle 413 having a semi-circular end away from the nut 412. When rotating the first screw 405, the three handles 413 on the nut 412 can be used for rotation, making operation more convenient and effortless. The inner walls of both the first semi-circular buckle 406 and the second semi-circular buckle 407 have several anti-slip textures 411 evenly distributed on their inner walls. When clamping the push rod and extension rod 2, several anti-slip textures 411 can increase the friction between the push rod and the first semi-circular buckle 406 and the second semi-circular buckle 407, making the clamping effect better.

[0031] Reference Figure 3 and Figure 4As shown in this embodiment: each of the four fixing devices 5 includes a rectangular plate 501. Rectangular blocks 502 are fixedly connected to both sides of the rectangular plate 501. A rotating rod 503 is rotatably connected to one end of two rectangular blocks 502 that are close to each other. A ring 504 is fixedly connected to the arc surface of the rotating rod 503. A first clamping plate 505 is fixedly connected to the arc surface of the ring 504. A sliding plate 506 is slidably connected to one side of the first clamping plate 505. The sliding plate 506 completely penetrates the first clamping plate 505. A second clamping plate 507 is fixedly connected to the lower surface of the sliding plate 506. A third screw 509 is rotatably connected to the upper surface of the second clamping plate 507. The third screw 509 is threadedly connected to the first clamping plate 505. When the base 3 is placed on a workbench or other relatively smooth surface, the first clamping plate 505 and the second clamping plate 507 can be used. By rotating the third screw 509, the second clamping plate 507 is moved towards the first clamping plate 505, thereby clamping the entire clamp onto the platform according to its thickness, achieving the effect of fixing the entire clamp. Several rubber strips 508 are fixedly connected to the upper surface of the second clamping plate 507, and these rubber strips 508 are evenly distributed on the second clamping plate 507. When the clamp is clamped onto the platform using the first clamping plate 505 and the second clamping plate 507, the rubber strips 508 on the second clamping plate 507 increase the friction between the clamp and the platform, resulting in a better fixing effect. Several suction cups 510 are fixedly connected to the lower surface of the base 3, and these suction cups 510 are evenly distributed on the lower surface of the base 3. When the clamp is placed on the platform, it can be attracted to the platform using the suction cups 510 on the bottom of the base 3, further enhancing the fixing effect of the device.

[0032] In terms of working principle, when the length of the push rod needs to be adjusted, a corresponding clamp is required to hold and fix the push rod so that the length can be successfully adjusted. However, since the diameter of the push rod is different, it is necessary to constantly change the corresponding clamp when dealing with push rods of different diameters. By setting up the clamping device 4, the first semicircular buckle 406 and the second semicircular buckle 407 can clamp push rods of different diameters without changing the clamp, thereby reducing the cost of use and increasing the work efficiency. The specific operating steps of the clamping device 4 are as follows: When the push rod needs to be adjusted in length, it needs to be placed on the arc surface of the two first semicircular buckles 406. After placement, the four second screws 408 located on the two second semicircular buckles 407 can be rotated. When rotating the second screws 408, the knob 409 on one end of the second screw 408 can be used. The four semicircular grooves 410 on the arc surface of the knob 409 allow the operator to insert their fingers into the semicircular grooves 410 to rotate the knob 409, making it easier for the operator to apply force. When the second screws 408 are rotated, they will drive the second semicircular buckles 407 to move towards the first semicircular buckles 406, thereby clamping and fixing the push rod. After clamping, the first semicircular buckle 406 and the second semicircular buckle 407 connected to the support plate 403 can slide along the rectangular groove 401 by rotating the first screw 405 located in the rectangular groove 401. At the same time, the support plate 403 will also slide in the same direction along the slide bar 414, thereby increasing the transmission efficiency of the support plate 403. The first screw 405 can be rotated by using the three grips 413 on the side of the nut 412, which makes the operation of rotating the first screw 405 simpler and more convenient. The several anti-slip textures 411 located on the inner side of the first semicircular buckle 406 and the second semicircular buckle 407 can increase the friction between the semicircular buckle and the push rod, thereby increasing the clamping effect.

[0033] In this utility model, by setting a fixing device 5, when it is necessary to use the clamp to adjust the length of the push rod, the clamp needs to be placed on a table or a platform. However, after placement, the clamp may fall off the platform and be damaged due to severe vibration or accidental collision. By setting a fixing device 5, the clamp is fixed to the platform using the first clamp 505 and the second clamp 507 located on both sides of the base 3, preventing the clamp from falling off the platform. The specific operation steps of the fixing device 5 are as follows: When it is necessary to use the clamp to adjust the length of the push rod, the clamp needs to be placed on the workbench and fixed. Once the clamp is placed on the workbench, the operator can rotate the four rotating rods 503 located on both sides of the base 3. These four rotating rods 503 are connected to the base 3 via rectangular plates 501 and rectangular blocks 502. As the rotating rods 503 are rotated, the rings 504 connected to them rotate at the same angle. When the rings 504 rotate, the first clamping plate 505 connected to it, and the second clamping plate 507 connected to the first clamping plate 505 via a third screw 509 and a sliding plate 506, also rotate with the rings 504. When the second clamping plate 507 rotates to a state relatively parallel to the bottom surface of the workbench, the rotation of the rotating rods 503 and the rings 504 can be stopped. At this point, the third screw 509 can be rotated. As the third screw 509 is rotated, it will cause the second clamping plate 507 to slide upward inside the first clamping plate 505 with the help of the sliding plate 506. This will cause the second clamping plate 507 to move towards the first clamping plate 505. Then, depending on the thickness of the worktable, when the second clamping plate 507 rises to make full contact with the bottom surface of the worktable, it will work together with the first clamping plate 505 to fix the base 3 to the worktable by pressing it. This completes the fixing of the clamp. The suction cups 510 located under the base 3 can be attached to the worktable when the base 3 is placed, making the fixing effect of the fixing device 5 more stable. The rubber strips 508 located on the second clamping plate 507 can increase the friction between the second clamping plate 507 and the bottom surface of the worktable when the second clamping plate 507 contacts the bottom surface of the worktable, thus improving the fixing effect.
