Description

Technical Field

[0001] This utility model relates to the field of facility agriculture engineering technology, specifically to a film-pressing card disassembly pliers. Background Technology

[0002] Film pressing clips are widely used in prefabricated plastic greenhouses due to their low price and good fixing effect. In order to maintain a good fixing effect on the plastic greenhouse film, the film pressing clips must tightly wrap around the film rolling rod. To enhance the strength and tightness of the film pressing clips, multiple reinforcing steel wires are added during the design and manufacturing process. Although this ensures that the film pressing clips have sufficient elasticity, it also causes assembly difficulties.

[0003] Currently, there are few tools specifically designed for loading and unloading film-pressing cards. Most operations rely on manual methods or the use of mechanical tools. Because film-pressing cards have high elasticity and burrs on their edges, manual handling not only easily damages the greenhouse film, causing it to lose its original toughness and integrity, but also easily cuts fingers, posing both safety hazards and slowing down assembly. These problems, to some extent, limit the application of film-pressing cards. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a film-pressing card removal pliers. By adjusting the height of the top support, it can adapt to film-pressing cards of different specifications. During the removal of the film-pressing card, it can avoid squeezing the greenhouse film, and achieve quick removal of the film-pressing card without damaging the greenhouse film. It has the advantages of simple structure, convenient use, and time and labor saving.

[0005] The technical solution of this utility model is as follows: This utility model is a pressure-film card removal plier, which is special in that: the pressure-film card removal plier includes a first clamp body, a second clamp body, a top support base and a top support. The first clamp body and the second clamp body are connected by a pin. The top support is set on the top support base and is movably connected to the top support base. The top support base is connected to the first clamp body and the second clamp body by a pin and can rotate independently around the pin. The upper end of the top support base is connected to the first clamp body and the second clamp body by two tension springs respectively.

[0006] Furthermore, the first clamp body includes a first handle and a first working arm located on the same side, with the first handle positioned below the first working arm; the second clamp body includes a second handle and a second working arm located on the same side, with the second handle positioned below the second working arm; and the connecting portion of the first handle and the first working arm is connected to the connecting portion of the second handle and the second working arm via a pin.

[0007] Furthermore, two arc-shaped arms are provided on the upper sides of the first and second action arms, and the ends of the arc-shaped arms are bent inward into a hook shape.

[0008] Furthermore, the two tension springs are respectively connected to the lower parts of the first and second action arms.

[0009] Furthermore, the length of the first actuating arm is less than the length of the first handle, and the length of the second actuating arm is less than the length of the second handle.

[0010] Furthermore, the top support base has a C-shaped opening structure with pin holes on both sides through which the pin shaft can pass.

[0011] Furthermore, the top support includes an arc-shaped plate, a screw rod, and a nut. The screw rod is located below the arc-shaped plate, and a screw hole matching the screw rod is provided above the top support base. The screw rod and the screw hole are fixed together by the nut.

[0012] Furthermore, the top support also includes a cushion, which is positioned above the curved plate.

[0013] Furthermore, the nut is a knurled, hand-tightening round nut.

[0014] This utility model provides a pressure-film card removal pliers, including a first pliers body, a second pliers body, a top support base, and a top support. The first pliers body includes a first handle and a first actuating arm located on the same side, with the first handle positioned below the first actuating arm. The second pliers body includes a second handle and a second actuating arm located on the same side, with the second handle positioned below the second actuating arm. The connecting part of the first handle and the first actuating arm is connected to the connecting part of the second handle and the second actuating arm via a pin. The top support is connected to the top support base via a screw hole in the center of the top support base, and its length is freely adjustable. When the removal pliers are working, the top support is stable in the middle of the pressure-film card. The first and second actuating arms apply a pulling force to both sides of the pressure-film card, opening it. Each of the first and second actuating arms has two arc-shaped arms, with the ends of the arc-shaped arms bent inward into a hook shape. The length of the first actuating arm is shorter than the length of the first handle, and the length of the second actuating arm is shorter than the length of the second handle. The four arc-shaped arms work together to keep the pressure-film card stable and evenly stressed during the opening process. The hook-shaped ends can better grip the edge of the pressure-film card. The pressure-film card removal pliers have a force-saving structure, making the removal process more time-saving and labor-saving. The top support base is connected to the first and second clamping bodies via a pin and can rotate independently around the pin. This independent rotation provides a smooth feel and easy operation for the card clamping pliers. The upper end of the top support base is connected to the first and second operating arms via two identical tension springs. The tension springs ensure that the top support base and the top support are always positioned on the center line of the angle formed by the first and second operating arms when the clamping bodies rotate around the pin. Therefore, when gripping card clamps of different sizes, the top support can always be supported at the center of the back of the card, providing stable support. Simultaneously, the two tension springs allow the card clamping pliers to be closed when not in use, facilitating storage.

[0015] Therefore, this utility model has the following advantages:

[0016] 1. This utility model has a simple structure, is easy to use, saves time and effort, and can be adapted to different specifications of pressure film cards by adjusting the height of the top support, thus having a wide range of applications;

[0017] 2. This utility model can avoid squeezing the greenhouse film during the disassembly of the film pressing card, and can quickly disassemble the film pressing card without damaging the film; it protects the safety of assembly personnel and prevents the film pressing card from scratching their fingers.

[0030] The overall scheme of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0031] See Figures 1 to 4The structure of this utility model includes a first clamp body 1, a second clamp body 2, a top support base 3, and a top support 4. The first clamp body 1 includes a first handle 1.1 and a first actuating arm 1.2 located on the same side, with the first handle 1.1 positioned below the first actuating arm 1.2. The second clamp body includes a second handle 2.1 and a second actuating arm 2.2 located on the same side, with the second handle 2.1 positioned below the second actuating arm 2.2. The connecting parts of the first handle 1.1 and the first actuating arm 1.2 are connected to the connecting parts of the second handle 2.1 and the second actuating arm 2.2 via a pin 5. The top support 4 is connected to the top support base 3 via a screw hole in the center of the top support base 3, and its length can be freely adjusted. When the disassembly clamp is in operation, the top support 4 is stably positioned in the middle of the pressure plate 8, and the first 1.2 and the second actuating arm 2.2 apply a pulling force to both sides to the pressure plate 8, opening the pressure plate 8.

[0032] The first actuating arm 1.2 and the second actuating arm 2.2 each have two arc-shaped arms on their upper sides. The ends of the arc-shaped arms are bent inward into hook shapes. The length of the first actuating arm 1.2 is less than the length of the first handle 1.1, and the length of the second actuating arm 2.2 is less than the length of the second handle 2.1. The four arc-shaped arms work together to keep the pressure-sensitive card 8 stable and evenly stressed during the opening process. The hook-shaped ends can better grip the dovetail groove 8.1 on the edge of the pressure-sensitive card 8. The pressure-sensitive card removal pliers have a force-saving structure, making the removal process more time-saving and labor-saving.

[0033] The top support base 3 has a C-shaped opening structure and pin holes on both sides. The pin shaft 5 passes through the pin holes and is connected to the first clamp body 1 and the second clamp body 2. It can rotate independently around the pin shaft 5, which makes the pressure film card removal clamp have a smooth feel and smooth operation.

[0034] The upper end of the top support base 3 is connected to the lower part of the first working arm 1.2 and the second working arm 2.2 by two tension springs 6 of the same specification. The two tension springs 6 of the same specification ensure that the top support base 3 and the top support 4 are always on the center line of the angle formed by the first working arm 1.2 and the second working arm 2.2 when the clamping body 1 and the second clamping body 2 rotate around the pin 5. Therefore, when the pressure card removal pliers grasp pressure cards 8 of different specifications, the top support 4 can always be supported at the center position of the back of the pressure card 8, providing stable support for the pressure card 8; at the same time, the two tension springs 6 can keep the pressure card removal pliers in a closed state when not in use, which is convenient for storage.

[0035] See Figure 5 The top support 4 includes a screw 4.2 that matches the screw hole of the top support base 3. An arc plate 4.1 is provided at the contact point between the top of the screw 4.2 and the pressure film card 8, and a soft pad 4.3 is fixed on the arc plate 4.1. The screw 4.2 and the screw hole are fixed by a nut 4.4, and the nut 4.4 is a knurled hand-tightening round nut.

[0036] The curved plate 4.1 provides a stable support surface for the pressure card 8, forming a five-point stable structure with the four arc-shaped arm gripping points; the soft pad 4.3 ensures flexible contact between the two, avoiding hard damage to the pressure card 8; by rotating the top support 4, the length of the top support 4 can be adjusted to fit different specifications of pressure cards 8. When the nut 4.4 on the screw 4.2 is tightened downwards, the top support base 3, the top support 4, and the nut 4.4 interact to form a rigid composite, and finally the top support 4 is fixed on the top support base 3. The knurled hand-tightening nut can also be turned by hand in the tightened state, making it convenient to adjust the length of the top support during use.

[0037] See Figure 6 The pressure-membrane card 8, which is matched with the pressure-membrane card disassembly pliers of this utility model, has an open structure and is provided with four symmetrical dovetail grooves 8.1 and several reinforcing steel wires 8.2. The dovetail groove structure facilitates the positioning and gripping of the pressure-membrane card 8 by the first working arm 1.2 and the second working arm 2.2, and the reinforcing steel wires 8.2 give the pressure-membrane card 8 sufficient elasticity.

[0038] The method of using this utility model is as follows:

[0039] First, rotate the top support 4 according to the specifications of the pressure film card 8 to adjust the length of the top support 4. After determining the appropriate height, rotate the nut 4.4 to lock the top support 4.

[0040] The second step is to insert the pressure film removal pliers into the back of the pressure film 8, so that the two arc arms at the front ends of the first working arm 1.2 and the second working arm 2.2 hook into the dovetail grooves 8.1 on both sides of the pressure film 8, and the top support 4 presses against the back of the pressure film 8.

[0041] The third step is to apply continuous pressure to the first handle 1.1 and the second handle 2.1. Through the lever action of the first clamp body 1 and the second clamp body 2, the first action arm 1.2 and the second action arm 2.2 apply a pulling force to both sides to the four dovetail grooves 8.1 of the pressure plate 8. As the force gradually increases, the pressure plate removal clamp slowly opens the pressure plate 8.

[0042] Fourth step: Remove the open pressure film card 8 from the film winding rod 7, loosen the pressure film card removal pliers, and let the pressure film card 8 fall off the removal pliers.

[0043] It should be noted that when the pressure film removal pliers are used to install the pressure film card 8, the operation process is the reverse of the removal process.

[0044] The content of this utility model and the technical content not specifically described in the above embodiments are the same as the prior art.

[0045] The above are merely specific embodiments disclosed in this utility model, but the scope of protection disclosed in this utility model is not limited thereto. The scope of protection disclosed in this utility model shall be determined by the scope of protection of the claims.
