Technical Field

[0001] This utility model relates to the field of hydraulic pliers technology, specifically a hydraulic pliers with an anti-pinch structure. Background Technology

[0002] Hydraulic pliers are tools that use hydraulic principles to cut or crimp certain materials. They are mainly used in various aspects, such as cutting wires and cables, disassembling and installing automotive parts, sometimes cutting metal parts, and crimping cable connectors.

[0003] In existing technology, the hydraulic crimping pliers commonly used in factories are made by a hydraulic pump supplying hydraulic pressure through pipelines. A person manually puts the metal head on the wire and then uses the hydraulic pliers to squeeze it to form the wire.

[0004] However, if not handled carefully, it is possible to squeeze the fingers, or even crush them. Therefore, it is necessary to design a hydraulic clamp that can prevent fingers from being pinched. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic clamp with an anti-pinch structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic clamp with an anti-pinch structure, comprising: a mounting plate, a hydraulic clamp assembly disposed on the top of the mounting plate, anti-pinch components disposed on both sides of the hydraulic clamp assembly, a switch box disposed on one side of each anti-pinch component, a protective shell disposed on the upper surface of the hydraulic clamp assembly, each anti-pinch component comprising a support column, a lifting cylinder, a touch switch and an electric push rod, the support column being fixedly mounted on the upper surface of the mounting plate, a first cylindrical groove being formed at the top of the support column, the electric push rod being fixedly mounted in the cylindrical groove, the lifting cylinder being fixedly mounted on the output end of the electric push rod, and the touch switch being fixedly mounted on the upper surface of the support column.

[0007] Preferably, an annular belt is provided on one side of the support, and a second cylindrical groove is provided at the bottom of the lifting cylinder. A limiting ring is fixedly connected to the bottom side wall of the second cylindrical groove, and the limiting ring is slidably connected to the second cylindrical groove.

[0008] Preferably, the hydraulic clamp assembly includes a base, a hydraulic housing, and pressure blocks. The base is fixedly mounted on the upper surface of the mounting plate, and the hydraulic housing is fixedly mounted on the base. The hydraulic housing has a notch, and pressure blocks are provided on both sides of the notch. An integrated circuit is disposed inside the hydraulic housing.

[0009] Preferably, a connecting block is fixedly connected to one end of the hydraulic unit housing, and a hydraulic pipe is fixedly connected to one end of the connecting block, the hydraulic pipe being connected to a hydraulic pump.

[0010] Preferably, the upper surface of the base is provided with sliding grooves on both sides, the bottom of the protective shell extends into the sliding grooves and is slidably connected thereto, and the protective shell is provided with through holes on both sides.

[0011] Preferably, a switch block is provided inside the switch box, and the switch block can slide on the switch box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention proposes a hydraulic clamp with two touch switches on both sides. The hydraulic clamp can only be started normally when both hands are placed on the touch switches. Since the cutting notch is set on the line connecting the two touch switches, it does not affect the handling of the object to be clamped. This effectively protects the worker's hands and prevents them from being easily squeezed. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0021] Please see Figure 1 , Figure 4 and Figure 5 This utility model provides a technical solution: a hydraulic clamp with an anti-pinch structure, comprising: a mounting plate 1, a hydraulic clamp assembly 5 on the top of the mounting plate 1, the hydraulic clamp assembly 5 being used to complete the hydraulic pressing work, anti-pinch components 3 being provided on both sides of the hydraulic clamp assembly 5, the anti-pinch components 3 being used to prevent the user from accidentally pinching their hand, a switch box 2 being provided on one side of each anti-pinch component 3, the switch box 2 being used to control whether the anti-pinch component 3 is active, and a protective shell 4 being provided on the upper surface of the hydraulic clamp assembly 5, the protective shell 4 also being used to prevent the hand from being pinched during the pressing process.

[0022] Each anti-pinch component 3 includes a support column 8, a lifting cylinder 9, a touch switch 10, and an electric push rod 11. The support column 8 is fixedly installed on the upper surface of the mounting plate 1, providing a certain support function. A first cylindrical groove 12 is formed at the top of the support column 8. The first cylindrical groove 12 is relatively deep. The electric push rod 11 is fixedly installed within the first cylindrical groove 12. The lifting cylinder 9 is fixedly installed at the output end of the electric push rod 11. The lifting and lowering of the output end of the electric push rod 11 can drive the lifting and lowering of the lifting cylinder 9. The touch switch 10 is fixedly installed on the upper surface of the support column 8. Switch 10 only closes when touched by a person, at which point the hydraulic clamp can work normally. A wide annular belt 13 is provided on one side of the support column 8. A second cylindrical groove 14 is provided at the bottom of the lifting cylinder 9. The support column 8 extends into the second cylindrical groove 14 and is slidably connected to it. A limit ring 15 is fixedly connected to the bottom side wall of the second cylindrical groove 14. The limit ring 15 is used to prevent the lifting cylinder 9 from detaching from the support column 8. The limit ring 15 is slidably connected to the second cylindrical groove 14. When the lifting cylinder 9 rises and falls, the limit ring 15 rises and falls within the annular belt 13.

[0023] When using it, first prepare the object to be clamped, hold it by hand and pass it between the two clamping blocks 20. Then start the electric push rod 11 and adjust the height of the lifting cylinder 9 to the most comfortable position and stop lifting. Then place both hands, the hand that may be holding the material, on the touch switch 10. It will automatically clamp and clamp. After clamping, remove the material. In special cases, such as when the other hand needs to do other work, or for disabled persons, the switch block 7 on the switch box 2 corresponding to the inconvenient hand can be switched to the other end. At this time, the touch switch 10 can be closed. Only one touch switch 10 is needed to operate. Example

[0024] Please see Figures 1-2 Based on Embodiment 1, the hydraulic clamp assembly 5 includes a base 17, a hydraulic housing 18, and a pressure block 20. The base 17 is fixedly installed on the upper surface of the mounting plate 1. The base 17 is made of insulating material to prevent electric leakage. The hydraulic housing 18 is fixedly installed on the base 17. The hydraulic housing 18 has a complex structure inside. A notch 19 is opened on the hydraulic housing 18. The pressure block 20 inside the notch 19 is used for squeezing. Pressure blocks 20 are provided on both sides of the notch 19. One pressure block 20 is stationary, while the other pressure block 20 can slowly move closer to the other pressure block 20 under the action of hydraulic pressure. An integrated circuit is provided inside the hydraulic housing 18. A connecting block 21 is fixedly connected to one end of the hydraulic housing 18. The connecting block 21 is used to connect the hydraulic line. A hydraulic pipe 6 is fixedly connected to one end of the connecting block 21. The hydraulic pipe 6 is connected to the hydraulic pump. Therefore, the pump will continuously provide pressure to the hydraulic device to ensure its normal operation.

[0025] In actual use, the hydraulic pump supplies fluid through the connecting block 21 into the hydraulic unit and pushes the pressure block 20 to move. Only one pressure block 20 can move, while the other pressure block 20 is fixed. The output of its hydraulic pump is also controlled by an integrated circuit. Example

[0026] Please see Figures 2-3 Based on Embodiment 2, sliding grooves are provided on both sides of the upper surface of the base 17. The bottom of the protective shell 4 extends into the sliding groove and is slidably connected to it. The protective shell 4 can slide in the sliding groove. When the protective shell 4 is in use, it is slid to the notch 19. When it is not in use, it is slid away from the notch 19. Through holes 16 are provided on both sides of the protective shell 4. The through holes 16 are to allow the material to continue working while providing protection. A switch block 7 is provided in the switch box 2. The switch block 7 and the touch switch 10 are connected in parallel. As long as one of them is closed, clamping can be achieved. The switch block 7 can slide on the switch box 2. When the switch block 7 slides to close the switch, the touch switch 10 is no longer effective and remains in a closed state.

[0027] In normal use, first prepare the object to be clamped, hold it by hand and pass it between the two clamping blocks 20. Then, start the electric push rod 11 and adjust the height of the lifting cylinder 9 to the most comfortable position and stop lifting. Then, place both hands, the hand that may be holding the material, on the touch switch 10. It will automatically clamp and clamp the object. After clamping, remove the material. In special cases, such as when the other hand needs to do other work, or for disabled persons, the switch block 7 on the switch box 2 corresponding to the inconvenient hand can be switched to the other end. This will close the touch switch 10. Only one touch switch 10 is needed for operation. During this process, the working state of the touch switch 10 can be changed by moving the toggle block. The hydraulic pump will supply liquid through the connecting block 21 to the hydraulic unit and push the clamping block 20 to move. Only one clamping block 20 can move, while the other clamping block 20 is fixed. The output of the hydraulic pump is also controlled by an integrated circuit.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
