[0030] The following will be combined Figure 1 - Figure 4 to make a further detailed description of the present application.

[0031] The embodiment discloses a high-performance clamp convenient to disassemble, which comprises a clamping body 1, a plurality of gear grooves 12 are formed in the outer wall of the clamping body 1, a clamping cavity 13 is fixedly connected at one end of the clamping body 1, and a locking assembly 2 is arranged in the clamping cavity 13.

[0032] Referring to Figures 2 to 4 , the locking assembly 2 comprises a tightening gear 21 rotating in the clamping cavity 13, the outer wall of the tightening gear 21 is engaged with the gear groove 12, two rotating columns 23 are fixedly connected at both ends of the tightening gear 21, a ratchet wheel 27 is fixedly connected at the other end of the rotating column 23, two rotating shafts 3 are rotatably connected at one side in the clamping cavity 13, a connecting block 31 is fixedly connected at the other side of the rotating shaft 3, a pressing plate 32 is fixedly connected at one side of the connecting block 31, two clamping blocks 26 are fixedly connected at the inner side of the pressing plate 32 close to the center, a gear block 24 is fixedly connected at the other end of the clamping block 26, the top end of the gear block 24 is engaged with the notch of the outer wall of the ratchet wheel 27, a plurality of first elastic members 25 are fixedly connected at the inner side of the pressing plate 32, and the other end of the first elastic member 25 is fixedly connected to the outer side of the gear block 24.

[0033] Thus, after the tape body 1 is placed in the designated pipeline position, the pressing plate 32 is pressed to drive the gear block 24 downward, the ratchet wheel 27 engaged with the gear block 24 is rotated under the force of the pressing plate 32, the rotating column 23 is rotated at the same time, the tightening gear 21 at the other end of the rotating column 23 is rotated, the tightening gear 21 is rotated at the same time to make the tape body 1 shrink inward, so that the tape body 1 can be adjusted according to the different diameters of the pipeline, and the disassembly and recovery to the original suitable fastening state are avoided due to the thermal expansion and cold contraction of the pipeline. At the same time, when the pressing plate 32 is pressed downward, the first elastic member 25 is used to support the gear block 24, so that the gear block 24 can always be engaged with the ratchet wheel 27 to stably drive the tightening gear 21 to rotate. When the clamp is disassembled, the pressing plate 32 is lifted upward, the pressing plate 32 drives the first elastic member 25 to move to the upper end, the gear block 24 is disengaged from the ratchet wheel 27, and the function of quick disassembly is realized.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 , the inside of the clamping cavity 13 is fixedly connected with a protection plate 15 on one side, the side of the protection plate 15 is fixedly connected with the baffle 34, the inside of the clamping cavity 13 is fixedly connected with a support plate 14 on the other side, the inside of the support plate 14 is fixedly connected with two support arms 22, the other end of the support arm 22 is rotatably arranged in the groove on the outer wall of the rotating column 23, the inside of the pressing plate 32 is fixedly connected with a plurality of second elastic members 33 near the other end, the other end of the second elastic member 33 is fixedly connected with the baffle 34, the baffle 34 is fixedly connected with the inside of the clamping cavity 13 on both sides, and the inside of the tape body 1 is fixedly connected with a sealing ring 11 near the center.

[0035] Thus, when the pressing plate 32 is pressed downward, due to the different force each time, the angle of pressing is also different. In order to prevent the pressing plate 32 from being pressed too hard to contact the tightening gear 21, the side of the protection plate 15 is used to block the pressing plate 32, so that the angle of pressing downward each time is the same. At the same time, when the ratchet wheel 27 drives the tightening gear 21 to rotate, the tightening gear 21 may shake, which may cause the belt body 1 to return to the original position and not be tightened in place. Therefore, the support arm 22 on the outer wall of the rotating column 23 is used to support the rotating column 23 and the tightening gear 21, so that the tightening gear 21 is more stable when rotating. Due to the different diameters of the pipes, the pressing plate 32 cannot be reset after being pressed for the first time and needs to be lifted to the specified position to continue to apply force, which affects the installation efficiency. Therefore, a plurality of second elastic members 33 are installed at the bottom of the pressing plate 32. The elasticity of the second elastic members 33 enables the pressing plate 32 to return to the original position after being pressed, improving the installation efficiency. Finally, the sealing ring 11 is used to seal the pipe connection to avoid leakage at the pipe interface.

[0036] The implementation principle of the high-performance clamp convenient to disassemble is as follows: after the clamp body 1 is placed at the specified pipeline position, the pressing plate 32 is pressed to drive the gear block 24 to press downward, the ratchet wheel 27 engaged with the gear block 24 is rotated under the force of the pressing plate 32, the rotating column 23 is rotated at the same time, the tightening gear 21 at the other end of the rotating column 23 is rotated, the tightening gear 21 is engaged with the gear groove 12 of the clamp body 1 at the bottom, and the tightening gear 21 is rotated at the same time to make the clamp body 1 shrink inward, so that the clamp body 1 can be adjusted according to the different diameters of the pipeline, and the original fastening state after disassembly cannot be restored due to thermal expansion and cold contraction of the pipeline. At the same time, when the pressing plate 32 is pressed downward under the force, the elastic force of the first elastic member 25 is used to support the gear block 24, so that the gear block 24 can always be engaged with the ratchet wheel 27 to stably drive the tightening gear 21 to rotate. When the clamp is disassembled, the pressing plate 32 is lifted upward, the pressing plate 32 drives the first elastic member 25 to move to the upper end, and the gear block 24 is disengaged from the ratchet wheel 27, so that the function of quick disassembly is realized. At the same time, when the pressing plate 32 is pressed downward, the pressing angle is different each time. In order to prevent the pressing plate 32 from being pressed too hard to contact the tightening gear 21, the side edge of the protective plate 15 is used to block the pressing plate 32, so that the pressing angle is the same each time. Due to the different diameters of the pipeline, the pressing plate 32 needs to be pressed multiple times. After the first pressing, the pressing plate 32 cannot be reset and needs to be lifted to the specified position to continue to press, which affects the installation efficiency. Therefore, multiple second elastic members 33 are installed at the bottom of the pressing plate 32, the elasticity of the second elastic members 33 is used to make the pressing plate 32 return to the original position after being pressed, and the installation efficiency is improved.

[0037] The above merely describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
