Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing component installation technology, specifically to a sealing component assembly clamp with a positioning element. Background Technology
[0002] During the maintenance of hydraulic cylinders, when replacing and installing the U-shaped seal ring on the end cover, since there are no special tools, it is usually done by hand with a screwdriver to pry and pick the seal ring into the groove, which is time-consuming and laborious, and can easily damage the seal ring.
[0003] A known Chinese utility model patent (Publication No.: 202220969422.X) discloses a sealing component assembly clamp with positioning elements, belonging to the technical field of U-shaped sealing ring installation fixtures. This sealing component assembly clamp with positioning elements includes a fixture assembly. The fixture assembly includes two hinges arranged vertically, a limiting element I, and two limiting elements II. Both hinges have through holes I near their ends, and the limiting elements I pass through two of the through holes I. Several through holes II are also evenly distributed on both hinges, and the two limiting elements II are respectively disposed through two of the through holes II. A positioning element for positioning the distance between the two hinges is also provided. This application not only facilitates the installation of the U-shaped sealing ring body and the end cap, but also facilitates the quick assembly and disassembly of the hinges, limiting elements I, and the two limiting elements II without the aid of external tools, while reducing the probability of the U-shaped sealing ring body falling off during clamping.
[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned sealing assembly clamp with positioning element: When limiting the two handles that open outward in the above technical solution, the clamping bolts need to be tightened, and when restoring the angle of the two handles, the clamping bolts need to be loosened. This process leads to the problem of low installation efficiency of U-shaped sealing rings. Therefore, a sealing assembly clamp with positioning element is proposed. Utility Model Content
[0005] This utility model proposes a sealing component assembly clamp with positioning elements, which solves the problem in related technologies where tightening the clamping bolts is required when limiting the two outward-opening handles, and loosening the clamping bolts is required when restoring the angle of the two handles, resulting in low installation efficiency of the U-shaped sealing ring.
[0006] The technical solution of this utility model is as follows: A sealing component assembly clamp with a positioning element, comprising:
[0007] A circular plate 1 and a circular plate 2 rotatably connected to the bottom of the circular plate 1; a pin 1 is detachably connected to the top of the circular plate 1.
[0008] The connecting frame is fixedly installed on the outer side wall of the first circular plate and the second circular plate respectively. A block is slidably connected to one side of the inner wall of the connecting frame, and a pin is detachably connected to the top of the block.
[0009] A limiting tooth is fixedly installed on the outer side wall of the circular plate. A limiting component is provided on the top of the connecting frame. A tooth block is fixedly installed on one side of the limiting component, and the tooth block is engaged with the limiting tooth.
[0010] The stop bar is fixedly installed on the outer side wall of the second circular plate.
[0011] Preferably, the limiting component includes a connecting rod, a connecting plate, and a torsion spring. The connecting rod and the torsion spring are respectively fixedly installed on the top of the connecting frame. The connecting plate is rotatably connected to the top of the connecting rod. One end of the torsion spring is connected to the bottom of the connecting plate. The toothed block is located on one side of the connecting plate.
[0012] Preferably, the outer wall of the first pin is provided with a thread, and a limiting cylinder is fixedly installed on the top of the first circular plate, and the thread is threadedly connected to the limiting cylinder.
[0013] Preferably, the outer wall of the second pin is provided with a second thread, and the top of the block is provided with a threaded groove, and the second thread and the threaded groove are threadedly connected.
[0014] Preferably, threaded rods are rotatably connected to both sides of the inner wall of the connecting frame, the threaded rods are threadedly connected to the block, and one end of the threaded rod is fixedly connected to a driven conical tooth.
[0015] Preferably, an active conical tooth is rotatably connected to one side of the inner wall of the connecting frame, and the active conical tooth and the driven conical tooth are meshed together.
[0016] Preferably, a handle is fixedly installed on one side of the connecting frame, and a rubber sleeve is fitted on the outer side wall of the handle.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] By using the set limiting components, toothed blocks, and limiting teeth, pressing the limiting components causes the toothed blocks and limiting teeth to separate, releasing the limiting of the first circular plate. This allows the connecting frame to be opened outwards to its end. When the two connecting frames are pulled back, the inclined surfaces of the toothed blocks and limiting teeth do not limit the first circular plate, allowing the two connecting frames to return to their original state. Therefore, it is not necessary to manually release the limiting of the first circular plate when the two connecting frames are pulled back, which helps to increase the installation efficiency of the U-shaped sealing ring.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0026] Please see Figure 1 - Figure 4 The present invention provides a sealing component assembly clamp with a positioning element, comprising:
[0027] Circular plate 1, rotatably connected to the bottom of circular plate 1, and a pin 4 detachably connected to the top of circular plate 1.
[0028] The connecting frame 3 is fixedly installed on the outer side wall of the circular plate 1 and the circular plate 2 respectively. A handle 18 is fixedly installed on one side of the connecting frame 3. A rubber sleeve 19 is fitted on the outer side wall of the handle 18. A block 5 is slidably connected to one side of the inner wall of the connecting frame 3. A pin 2 6 is detachably connected to the top of the block 5.
[0029] The limiting tooth 7 is fixedly installed on the outer side wall of the circular plate 1. The top of the connecting frame 3 is provided with a limiting component 8. A tooth block 9 is fixedly installed on one side of the limiting component 8. The limiting component 8 includes a connecting rod 81, a connecting plate 82 and a torsion spring 83. The connecting rod 81 and the torsion spring 83 are respectively fixedly installed on the top of the connecting frame 3. The top end of the connecting plate 82 is rotatably connected to the top end of the connecting rod 81. One end of the torsion spring 83 is connected to the bottom end of the connecting plate 82. The tooth block 9 is located on one side of the connecting plate 82 and is engaged with the limiting tooth 7.
[0030] The stop bar 10 is fixedly installed on the outer side wall of the circular plate 2;
[0031] In use, install pin 4 on top of circular plate 1, and screw pin 6 onto block 5. When installing the U-shaped sealing ring body, place the U-shaped sealing ring body between the front and rear pins 4 and the two pins 6. Press the connecting plate 82 to separate the toothed block 9 from the limiting tooth 7, releasing the limiting of circular plate 1. Open the connecting frame 3 outward to its end using handle 18. After releasing the connecting plate 82, the torsion spring 83 will cause the connecting plate 82 to rotate back to its original position, causing the toothed block 9 to engage with the limiting tooth 7. Limit the opening angle of the connecting frame 3 to cause the U-shaped sealing ring to undergo elastic deformation. Then, place it into the end cover and align the U-shaped sealing ring with the sealing groove of the end cover. Hold the two handles 18 to drive the two connecting frames 3 to retract. At this time, under the action of the inclined surface of the tooth block 9 and the limiting tooth 7, the connecting plate 82 rotates, causing the two connecting frames 3 to return to their original state. The U-shaped sealing ring automatically enters the groove under its own elastic action. Finally, it can be smoothed by hand. The stop bar 10 prevents the connecting plate 82 from rotating in the direction of the circular plate 1.
[0032] Specifically, the outer wall of the pin 4 is provided with thread 11, and the top of the circular plate 1 is fixedly installed with a limiting cylinder 12, and the thread 11 and the limiting cylinder 12 are threadedly connected.
[0033] Rotate pin 4 to connect thread 11 with limit cylinder 12, making it easier to install pin 4 on limit cylinder 12.
[0034] Specifically, the outer wall of the second pin 6 is provided with a second thread 13, and the top of the block 5 is provided with a threaded groove 14, and the second thread 13 and the threaded groove 14 are threadedly connected.
[0035] Rotate pin 26 to connect thread 213 with thread groove 14, making it easier to install pin 26 on block 5.
[0036] Specifically, threaded rods 15 are rotatably connected to both sides of the inner wall of the connecting frame 3. The threaded rods 15 are threadedly connected to the block 5. One end of the threaded rods 15 is fixedly connected to a driven conical tooth 16. One side of the inner wall of the connecting frame 3 is rotatably connected to an active conical tooth 17. The active conical tooth 17 and the driven conical tooth 16 are meshed together.
[0037] Rotating the active bevel gear 17 drives the driven bevel gear 16 to rotate, the driven bevel gear 16 drives the threaded rod 15 to rotate, the threaded rod 15 drives the block 5 to move, and the block 5 drives the second pin 6 to move to adjust the distance between it and the first pin 4. The distance between the second pin 6 and the first pin 4 is adjusted according to the actual situation.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
