However, at the same time, we need to ensure that the gas is not easy to leak and the overall stability of the device. Summary of the Invention

[0004] The purpose of the utility model is to provide a pneumatic spring claw of a flexible buckle clamp to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

The first air inlet pipe and the clamp tail cover are fastened together, the clamp tail cover and the clamp piston are slidingly connected, the clamp tail cover and the clamp cylinder are connected, the clamp tail cover and the piston guide rod are fastened together, the clamp piston and the elastic claw are slidingly connected, the clamp piston and the pushing rod abut, the clamp piston and the clamp cylinder are slidingly connected, the clamp piston and the piston guide rod are slidingly connected, the second air inlet pipe and the clamp cylinder are fastened together, the elastic claw and the pushing rod abut, the elastic claw and the piston guide rod are fastened together, the pushing rod and the clamp cylinder are slidingly connected, the magnetic ring and the clamp piston are fastened together, and the magnetic ring and the clamp cylinder are slidingly connected.

[0007] The clamp cylinder is used as the main installation base for the installation of other components. The clamp cylinder provides a sealing environment. The piston guide rod is used as a fixing device for the installation and fixation of the elastic claw. The first air inlet pipe and the second air inlet pipe are used as the main air inlet structure for conveying gas. The gas is conveyed through the first air inlet pipe and flows through the clamp tail cover to the inside of the clamp cylinder, so that the air pressure at the end of the clamp cylinder close to the clamp tail cover increases. The increased air pressure at the end of the clamp cylinder close to the clamp tail cover pushes the clamp piston to move toward the end of the clamp cylinder where the air pressure is low. The movement of the clamp piston drives the tightening rod to move, and the movement of the tightening rod drives the elastic claw to contract. The elastic claw is contracted to clamp the buckle. The magnetic ring is used as the main detection device to detect the grasping signal.

[0008] Furthermore, a first air outlet is provided on the first air inlet pipe, and the first air outlet is communicated with the tail cover of the clamp.

[0009] The gas enters the interior of the clamp cylinder through the first gas outlet and the clamp tail cover, causing the air pressure at the end of the clamp cylinder close to the clamp tail cover to increase.

[0010] Furthermore, the fixture tail cover includes a cover body, a first tail cover sealing ring and a second tail cover sealing ring, the cover body is provided with a first air inlet hole, a first tail cover mounting groove and a second tail cover mounting groove, the first air outlet is connected to the first air inlet hole, the first tail cover sealing ring is placed on the first tail cover mounting groove, the first tail cover sealing ring and the piston guide rod are abutted, the first tail cover sealing ring and the first tail cover mounting groove are abutted, the second tail cover sealing ring is placed on the second tail cover mounting groove, the second tail cover sealing ring and the second tail cover mounting groove are abutted, the second tail cover sealing ring and the fixture cylinder are abutted, the cover body and the fixture cylinder are tightly connected, the cover body and the piston guide rod are tightly connected, and the cover body and the fixture piston are tightly connected.

[0011] The cover body serves as the main installation base and is used for the installation and positioning of other components. The first air inlet pipe is installed through the first air inlet hole, and the gas flows into the first air inlet hole from the first air outlet and flows into the interior of the fixture cylinder through the first air inlet hole, so that the air pressure inside the fixture cylinder near the end of the fixture tail cover increases. The first tail cover sealing ring and the second tail cover sealing ring serve as the main sealing devices. The first tail cover sealing ring is respectively in contact with the first tail cover mounting groove and the piston guide rod to block the connection gap between the cover body and the piston guide rod to provide a sealed environment, so that the gas in the fixture cylinder will not leak from the connection gap between the cover body and the piston guide rod. The second tail cover sealing ring is respectively in contact with the second tail cover mounting groove and the fixture cylinder to block the connection gap between the cover body and the fixture cylinder to provide a sealed environment, so that the gas in the fixture cylinder will not leak from the connection gap between the cover body and the fixture cylinder.

[0012] Furthermore, the clamp piston includes a piston body and a piston sealing ring. The piston body is provided with a piston mounting groove. The piston sealing ring is placed in the piston mounting groove. The piston sealing ring and the piston mounting groove are abutted. The piston sealing ring and the clamp cylinder are abutted. The piston body and the clamp cylinder are slidingly connected. The piston body and the cover body are tightly connected. The piston body and the elastic claw are tightly connected. The piston body and the pushing rod are tightly connected. The piston body and the piston guide rod are slidingly connected.

[0013] The piston body serves as the main sealing component. The piston body divides the clamp cylinder into two closed environments. Gas is delivered to the inside of the clamp cylinder through the first air inlet hole to increase the pressure of the closed environment in the clamp cylinder near the cover body. The pressure is increased by delivering gas, and the piston body is pushed to move toward the end of the clamp cylinder close to the elastic claw. The movement of the piston body drives the tightening rod to move, and the movement of the tightening rod drives the elastic claw to contract. The buckle is grasped by the contraction and clamping of the elastic claw.

[0014] Furthermore, a second air outlet is provided on the second air inlet pipe, and the second air outlet is connected to the clamp cylinder.

[0015] When it is transported to the designated position, gas is delivered to the clamp cylinder through the second air outlet to increase the pressure of the closed environment of the clamp cylinder near the elastic claw. At the same time, the first air outlet stops delivering gas. The pressure is increased by delivering gas to push the piston body toward the end of the clamp cylinder near the cover body, and also push the tightening rod toward the end of the clamp cylinder near the cover body. The force exerted by the tightening rod on the elastic claw disappears, the elastic claw no longer contracts, and the buckle disengages.

[0016] Furthermore, a groove is provided on the elastic claw, and the elastic claw is made of elastic material.

[0017] The buckle is connected through the groove, which makes it difficult for the buckle to fall off during transportation. The elastic claw is made of elastic material to ensure that the elastic claw can restore its shape without external force, thereby achieving repeated clamping.

[0018] Furthermore, the clamp cylinder includes a cylinder body, a first cylinder sealing ring and a second cylinder sealing ring. The cylinder body is provided with a first cylinder groove, a second cylinder groove and a second air inlet. The first cylinder sealing ring is placed in the first cylinder groove, the first cylinder sealing ring and the first cylinder groove are abutted, the first cylinder sealing ring and the pushing rod are abutted, the second cylinder sealing ring is placed in the second cylinder groove, the second cylinder sealing ring and the second cylinder groove are abutted, the second cylinder sealing ring and the pushing rod are abutted, the cylinder body and the cover body are fastened together, the cylinder body and the piston body are slidingly connected, the second air inlet and the second air outlet are connected, the cylinder body and the pushing rod are slidingly connected, and the cylinder body and the magnetic ring are slidingly connected.

[0019] The cylinder body serves as the main closed environment. The first cylinder sealing ring is respectively in contact with the first cylinder groove and the pushing rod to achieve initial sealing. The second cylinder sealing ring is respectively in contact with the second cylinder groove and the pushing rod to achieve secondary sealing, ensuring that the gas inside the cylinder body will not leak from the connection gap between the cylinder body and the pushing rod. The gas delivered from the second air outlet is sent into the interior of the cylinder body through the second air inlet hole to increase the pressure in the cylinder body near the end of the elastic claw to push the pushing rod and the piston body to move toward the side of the cover body.

[0020] Furthermore, a magnetic fixing groove is provided on the cylinder body, a magnetic switch is provided on the magnetic fixing groove, and the magnetic fixing groove and the magnetic switch are tightly connected.

[0021] The magnetic switch on the magnetic fixing slot detects the signal on the magnetic ring to detect the grasping action.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Fully automatic operation is achieved by detecting the grabbing signal and the releasing signal through the magnetic ring. When the elastic claw is needed to clamp the buckle, gas is delivered through the first air outlet, and the gas enters the cylinder body near the end of the cover body through the first air inlet. The gas enters the cylinder body to increase the pressure of the cylinder body near the cover body, so as to push the piston body to move in the direction close to the elastic claw. The movement of the piston body drives the tightening rod to move, and the movement of the tightening rod causes the elastic claw to contract, and the elastic claw contracts to clamp the buckle. When the buckle is sent to the specified position, the first air outlet stops gas delivery, and the second air outlet starts to deliver gas, and the gas enters the cylinder body near the end of the elastic claw through the second air inlet. The gas enters the cylinder body to increase the pressure of the end of the cylinder body away from the cover body, so as to push the piston body to move in the direction close to the cover body. The movement of the piston body drives the pushing rod to move in the direction close to the cover body, the force of the pushing rod on the elastic claw disappears, the elastic claw is released and restored, and the buckle is disengaged.

[0024] 2. Various buckle products can be grabbed through the grooves on the elastic claws. Large buckles can be grabbed by changing the specifications of the elastic claws.

[0025] 3. The device is sealed by the first tail cover sealing ring, the second tail cover sealing ring, the first cylinder sealing ring and the second cylinder sealing ring to ensure that gas will not leak and improve the grasping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The clamp cylinder 8 serves as the main installation base for the installation of other components. The clamp cylinder 8 provides a sealed environment. The piston guide rod 9 serves as a fixing device for the installation and fixation of the elastic claw 6. The first air inlet pipe 1 and the second air inlet pipe 4 serve as the main air inlet structure for conveying gas. The gas is conveyed through the first air inlet pipe 1 and flows through the clamp tail cover 2 to the inside of the clamp cylinder 8, so that the air pressure at the end of the clamp cylinder 8 close to the clamp tail cover 2 increases. The increased air pressure at the end of the clamp cylinder 8 close to the clamp tail cover 2 pushes the clamp piston 3 to move toward the end of the clamp cylinder 8 with low air pressure. The movement of the clamp piston 3 drives the tightening rod 7 to move. The movement of the tightening rod 7 drives the elastic claw 6 to contract. The elastic claw 6 contracts to clamp the buckle 5.

[0033] like Figure 2 - Figure 3 As shown, the first air inlet pipe 1 is provided with a first air outlet 11 , and the first air outlet 11 is communicated with the fixture tail cover 2 .

[0034] The gas passes through the first gas outlet 11 and the clamp tail cover 2 into the interior of the clamp cylinder 8, causing the air pressure at the end of the clamp cylinder 8 close to the clamp tail cover 2 to increase.

[0035] like Figure 1 - Figure 3 As shown, the clamp tail cover 2 includes a cover body 21, a first tail cover sealing ring 22 and a second tail cover sealing ring 23. The cover body 21 is provided with a first air inlet 211, a first tail cover mounting groove 212 and a second tail cover mounting groove 213. The first air outlet 11 is connected to the first air inlet 211. The first tail cover sealing ring 22 is placed on the first tail cover mounting groove 212. The first tail cover sealing ring 22 and the piston guide rod 9 are abutted. The first tail cover sealing ring 22 and the first tail cover mounting groove 212 are abutted. The second tail cover sealing ring 23 is placed on the second tail cover mounting groove 213. The second tail cover sealing ring 23 and the second tail cover mounting groove 213 are abutted. The second tail cover sealing ring 23 and the clamp cylinder 8 are abutted. The cover body 21 and the clamp cylinder 8 are tightly connected. The cover body 21 and the piston guide rod 9 are tightly connected. The cover body 21 and the clamp piston 3 are tightly connected.

[0036] The cover body 21 serves as the main installation base, and is used for the installation and positioning of other components. The first air inlet pipe 1 is installed through the first air inlet hole 211, and the gas flows into the first air inlet hole 211 from the first air outlet 11, and flows into the inside of the clamp cylinder 8 through the first air inlet hole 211, so that the air pressure inside the clamp cylinder 8 near the end of the clamp tail cover 2 increases. The first tail cover sealing ring 22 and the second tail cover sealing ring 23 serve as the main sealing devices. The first tail cover sealing ring 22 is respectively in contact with the first tail cover mounting groove 212 and the piston guide rod 9 to block the connection gap between the cover body 21 and the piston guide rod 9 to provide a sealed environment, so that the gas in the clamp cylinder 8 will not leak from the connection gap between the cover body 21 and the piston guide rod 9. The second tail cover sealing ring 23 is respectively in contact with the second tail cover mounting groove 213 and the clamp cylinder 8 to block the connection gap between the cover body 21 and the clamp cylinder 8 to provide a sealed environment, so that the gas in the clamp cylinder 8 will not leak from the connection gap between the cover body 21 and the clamp cylinder 8.

[0037] like Figure 1 - Figure 3 As shown, the clamp piston 3 includes a piston body 31 and a piston sealing ring 32. A piston mounting groove 311 is provided on the piston body 31. The piston sealing ring 32 is placed in the piston mounting groove 311. The piston sealing ring 32 and the piston mounting groove 311 are abutted. The piston sealing ring 32 and the clamp cylinder 8 are abutted. The piston body 31 and the clamp cylinder 8 are slidingly connected. The piston body 31 and the cover body 21 are firmly connected. The piston body 31 and the elastic claw 6 are firmly connected. The piston body 31 and the tightening rod 7 are firmly connected. The piston body 31 and the piston guide rod 9 are slidingly connected.

[0038] The piston body 31 serves as the main sealing component. The clamp cylinder 8 is divided into two closed environments by the piston body 31. Gas is delivered to the inside of the clamp cylinder 8 through the first air inlet 211 to increase the pressure of the closed environment in the clamp cylinder 8 near the cover body 21. The pressure is increased by delivering gas, and the piston body 31 is pushed to move toward the end of the clamp cylinder 8 near the elastic claw 6. The movement of the piston body 31 drives the tightening rod 7 to move. The movement of the tightening rod 7 drives the elastic claw 6 to contract. The elastic claw 6 is contracted and clamped to achieve the capture of the buckle 5.

[0039] like Figure 1 - Figure 3 As shown, the second air inlet pipe 4 is provided with a second air outlet 41 , and the second air outlet 41 is connected to the clamp cylinder 8 .

[0040] After being transported to the designated position, gas is delivered to the clamp cylinder 8 through the second air outlet 41 to increase the pressure of the closed environment of the clamp cylinder 8 near the elastic claw 6. At the same time, the first air outlet 11 stops delivering gas. The pressure is increased by delivering gas to push the piston body 31 toward the end of the clamp cylinder 8 near the cover body 21, and also push the tightening rod 7 toward the end of the clamp cylinder 8 near the cover body 21. The force exerted by the tightening rod 7 on the elastic claw 6 disappears, the elastic claw 6 no longer contracts, and the buckle 5 is disengaged.

[0041] like Figure 1 - Figure 3 As shown, a groove 61 is provided on the elastic claw 6, and the elastic claw 6 is made of elastic material.

[0042] The buckle 5 is clamped by the groove 61, so that the buckle 5 is not easy to fall off during transportation. The elastic claw 6 is made of elastic material to ensure that the elastic claw 6 can restore its shape without external force, thereby achieving repeated clamping.

[0043] like Figure 1 - Figure 3 As shown, the clamp cylinder 8 includes a cylinder body 81, a first cylinder sealing ring 82 and a second cylinder sealing ring 83. The cylinder body 81 is provided with a first cylinder groove 811, a second cylinder groove 812 and a second air inlet 813. The first cylinder sealing ring 82 is placed in the first cylinder groove 811, the first cylinder sealing ring 82 and the first cylinder groove 811 are abutted, the first cylinder sealing ring 82 and the pushing rod 7 are abutted, the second cylinder sealing ring 83 is placed in the second cylinder groove 812, the second cylinder sealing ring 83 and the second cylinder groove 812 are abutted, the second cylinder sealing ring 83 and the pushing rod 7 are abutted, the cylinder body 81 and the cover body 21 are fastened together, the cylinder body 81 and the piston body 31 are slidingly connected, the second air inlet 813 is connected to the second air outlet 41, the cylinder body 81 and the pushing rod 7 are slidingly connected, and the cylinder body 81 and the magnetic ring 10 are slidingly connected.

[0044] The cylinder body 81 serves as the main closed environment. The first cylinder sealing ring 82 abuts against the first cylinder groove 811 and the pushing rod 7 respectively to achieve initial sealing. The second cylinder sealing ring 83 abuts against the second cylinder groove 812 and the pushing rod 7 respectively to perform secondary sealing to ensure that the gas inside the cylinder body 81 will not leak from the connection gap between the cylinder body 81 and the pushing rod 7. The gas delivered from the second air outlet 41 is sent into the interior of the cylinder body 81 through the second air inlet hole 813 to increase the pressure in the cylinder body 81 near the end of the elastic claw 6 to push the pushing rod 7 and the piston body 31 to move toward the side of the cover body 21.

[0045] like Figure 1 - Figure 3 As shown, the cylinder body 81 is also provided with a magnetic fixing groove 814, and a magnetic switch is provided on the magnetic fixing groove 814. The magnetic fixing groove 814 and the magnetic switch are fastened together.

[0046] The magnetic switch on the magnetic fixing slot 814 detects the signal on the magnetic ring 10 to detect the grabbing action.

[0047] The working principle of the present invention is as follows: the detection of the grab signal and the release signal is carried out through the magnetic switch and the magnetic ring 10 to realize full automatic operation. When the elastic claw 6 is needed to clamp the buckle 5, gas is delivered through the first air outlet 11, and the gas enters the cylinder body 81 near the end of the cover body 21 through the first air inlet 211. The gas enters the cylinder body 81 to increase the pressure of the cylinder body 81 near the end of the cover body 21, so as to push the piston body 31 to move toward the elastic claw 6. The movement of the piston body 31 drives the pushing rod 7 to move. The movement of the pushing rod 7 causes the elastic claw 6 to contract. The elastic claw 6 contracts to clamp the buckle 5. When the buckle 5 is sent to the specified position, the first air outlet 11 stops gas delivery, and the second air outlet 41 starts to deliver gas. The gas passes through the second air inlet 813 enters the cylinder body 81 near one end of the elastic claw 6, and the gas enters the cylinder body 81 to increase the pressure on the end of the cylinder body 81 away from the cover body 21, so as to push the piston body 31 to move toward the cover body 21. The movement of the piston body 31 drives the pushing rod 7 to move toward the cover body 21. The force exerted by the pushing rod 7 on the elastic claw 6 disappears, the elastic claw 6 is loosened and restored, and the buckle 5 is disengaged. Various buckles 5 can be grasped by the groove 61 on the elastic claw 6. The grasping of large buckles 5 can be achieved by replacing the specifications of the elastic claw 6. The device is sealed by the first tail cover sealing ring 22, the second tail cover sealing ring 23, the first cylinder sealing ring 82 and the second cylinder sealing ring 83 to ensure that the gas will not leak, thereby improving the grasping efficiency.
