[0034] See also Figures 1 to 5 Now, a metal wire clamp device provided by the utility model is described. A metal wire clamp device comprises a clamp body 100, two clamp heads 200, an elastic member and an unlocking handle 400.
[0035] The interior of the clamp body 100 is provided with a conical cavity 110, the front side of the conical cavity 110 has an outlet end, and the two sides of the conical cavity 110 are provided with guide slopes 111, and the guide slopes 111 are inclined inward from the back to the front, and the upper end surface of the clamp body 100 is provided with a through hole 121 connected to the conical cavity 110; two clamp heads 200 are symmetrically arranged in the conical cavity 110, and the outer side surfaces of the clamp heads 200 are provided with matching slopes 210 adapted to the guide slopes 111, and the inner side surfaces of the clamp heads 200 are provided with clamping surfaces, and the rear sides of the two clamping surfaces are relatively provided with notches 230; the elastic member is provided Placed in the conical cavity 110, the elastic component provides an elastic pre-tightening force for the two pliers heads 200 to move toward the front side, so that the two pliers heads 200 extend from the outlet end and the two clamping surfaces fit together to clamp the metal wire; the unlocking handle 400 is rotatably set on the top of the clamp body 100, and the lower end of the unlocking handle 400 is provided with a pushing block 410 that passes through the through hole 121. The pushing block 410 is inserted into the two notches 230. The pushing block 410 pushes the rear part of the two notches 230 backward as the unlocking handle 400 rotates, so that the two pliers heads 200 move backward and the two clamping surfaces are separated from each other.
[0036] The utility model provides a wire clamp device. Compared with the prior art, two clamp heads 200 are arranged in the conical cavity 110 of the clamp body 100. The elastic component of the conical cavity 110 pushes the two clamp heads 200 to extend from the outlet end. Under the cooperation of the guide slope 111 and the matching slope 210, the clamping surfaces of the two clamp bodies 100 are attached to each other and clamp the wire. The unlocking handle 400 is turned, and the unlocking handle 400 drives the pushing block 410 to push the two clamp heads 200 backward through the notch 230. The two clamp heads 200 move backward and the two clamping surfaces are separated from each other and the wire is released. When the wire clamp device provided by the utility model is used, the elastic component is used to provide elastic force for the two clamp heads 200. The two clamp heads 200 slide forward along the guide slope 111 on the corresponding side and approach each other, and finally the wire is clamped by the two opposite clamping surfaces. When the metal wire needs to be loosened, the unlocking handle 400 drives the pushing block 410 to push the two clamp heads 200 backward through the notch 230, and the two clamp heads 200 slide backward along the guide inclined surfaces 111 on the corresponding sides and move away from each other, and the two clamping surfaces separate to release the metal wire. The utility model provides a metal wire clamp device, which can stably clamp the metal wire, and it is also very labor-saving to loosen the metal wire, and has a simple structure and is easy to operate.
[0037] It is worth noting that the direction in which the opening end of the tapered cavity 110 of the clamp body 100 is set is defined as the front, and the direction away from the opening end is defined as the rear.
[0038] See also Figures 1 to 3The top of the clamp body 100 is detachably mounted with a clamp cover 120. The shapes of the clamp cover 120 and the clamp body 100 are adapted to each other. The upper end surface of the clamp body 100 is provided with a plurality of threaded holes in the circumferential direction. The corresponding positions of the clamp cover 120 are also provided with a plurality of connection holes 141. At the same time, the clamp cover 120 is provided with countersunk holes coaxially at the positions corresponding to the connection holes 141. A plurality of connection bolts are used to penetrate the connection holes 141 from top to bottom and are threadedly connected to the threaded holes. The clamp cover 120 is connected by connection bolts, which is convenient for disassembly and assembly of the clamp cover 120. When a certain component is worn or damaged, it can be replaced, which is convenient for maintenance.
[0039] The through hole 121 is opened in the middle of the clamp upper cover 120 and extends in the front-to-back direction to form a strip-shaped through hole 121. The unlocking handle 400 is installed in the middle of the clamp upper cover 120. The unlocking handle 400 and the clamp upper cover 120 are rotatably matched so that the push block 410 of the unlocking handle 400 can be inserted into the notch 230 through the through hole 121. The strip-shaped through hole 121 can provide space for the push block 410 to swing in the through hole 121.
[0040] In order to ensure that the matching bevel 210 of the pliers head 200 always slides with the guiding bevel 111 of the conical cavity 110, corresponding slideways and slide grooves are respectively provided on the matching bevel 210 and the guiding bevel 111, and two inclined slideways can also be respectively provided at the bottom of the accommodating groove, and the two inclined slideways have the same inclination as the guiding bevel 111 on the corresponding side, and at the same time, a corresponding inclined slide groove is provided on the lower end surface of the pliers head 200, and the inclined slide groove is an embedded groove, and both ends do not extend to the front and rear end surfaces of the pliers head 200, and the inclined slide slides in the inclined slide groove, so that when the pliers head 200 moves forward and backward, it is always ensured that the matching bevel 210 and the guiding bevel 111 are in contact with each other, and the sliding trajectory remains consistent. That is, the two pliers heads 200 move forward while moving closer to each other, and the two pliers heads 200 move backward while separating from each other. The embedded inclined slide can prevent the inclined slide from sliding out of the inclined slide, keeping the clamp head 200 only able to move forward and backward within a certain range, avoiding compression transition when moving backward and damaging the elastic component or getting stuck in the outlet end when moving forward.
[0041] A limit groove is opened in the front-to-back direction of the clamp body 100, and the inner sides of the two clamp heads 200 are respectively provided with limit blocks inserted into the limit groove. The width of the limit groove is greater than the width of the limit block. When the two clamp heads 200 move forward to the exit end, the two limit blocks fit each other; when the two clamp heads 200 move backward to the point where the two limit blocks respectively abut against the two sides of the limit groove in the width direction, the two clamp heads 200 will not be able to move backward any further, thereby effectively protecting the elastic component.
[0042] In addition, the height of the rear side of the lower end surface of the conical cavity 110 gradually increases, that is, the rear end of the conical cavity 110 forms a reducing groove with a gradually decreasing height. When the pliers head 200 moves backward to the reducing groove, the height of the pliers head 200 is greater than the height of the reducing groove. At this time, the pliers head 200 can no longer move backward, which can also effectively protect the elastic component.
[0043] See also Figure 1 and Figure 4 The upper end surface of the clamp upper cover 120 is provided with two lugs 122, which are integrally formed on the upper end surface of the clamp upper cover 120. The two lugs 122 are parallel to each other and are respectively located on the left and right sides of the through hole 121. The unlocking handle 400 passes through the space between the two lugs 122, so that the push block 410 passes through the through hole 121 and is inserted into the notch 230. The two sides of the unlocking handle 400 are respectively provided with rotating shafts 420, which respectively penetrate the through holes 121 on the two lugs 122, so that the unlocking handle 400 and the two lugs 122 are rotatably connected.
[0044] In some embodiments, see Figure 4 The pushing block 410 has a certain length, and the upper end of the pushing block 410 is integrally formed on the rear side of the lower end of the unlocking handle 400. At this time, the two rotating shafts 420 can be arranged on the left and right sides of the upper part of the pushing block 410, and the lower end of the pushing block 410 extends to the notch 230 of the two pliers heads 200.
[0045] Preferably, the front side of the lower end of the pushing block 410 has an arcuate surface, and the arcuate surface and the rear side of the lower end of the pushing block 410 have rounded corners, which can reduce local scratches caused by the pushing block 410 when pushing the rear of the notch 230.
[0046] In addition, a pressing handle 430 extending forward is provided at the upper end of the unlocking handle 400. The pressing handle 430 and the unlocking handle 400 are integrally formed. The joint between the pressing wrench and the unlocking handle 400 is in an arc transition, which reduces internal stress and improves structural strength. The pushing block 410 is provided at the rear side of the lower end of the unlocking handle 400. When the metal wire needs to be loosened, the end of the pressing handle 430 is pressed downward. The downward pressing method can make the unlocking method more convenient to apply force.
[0047] When the end of the pressing handle 430 is pressed against the upper end surface of the clamp cover 120, the end of the pushing block 410 will not fall out of the notch 230, but will always be pressed against the rear of the notch 230, avoiding the unlocking of the handle 400.
[0048] See also Figure 5, multiple anti-slip teeth 220 are arranged on both clamping surfaces from front to back, and the anti-slip teeth 220 are integrally formed on the clamping surfaces. The tips of the multiple anti-slip teeth 220 on the two clamping surfaces are all acute-angle structures, and the anti-slip teeth 220 are all tilted backwards. In addition, the multiple anti-slip teeth 220 on both sides are relatively staggered and interlocked, that is, the acute-angle structure of the anti-slip teeth 220 on one side is inserted between the two adjacent anti-slip teeth 220 on the other side. The multiple anti-slip teeth 220 that bite each other can make the metal wire clamping stability between the two better. In addition, when the forward pulling force of the metal wire is too large, the metal wire will drive the two clamp heads 200 to continue to move toward the outlet end, and the two guide inclined surfaces 111 will squeeze the two clamp heads 200 inward at the same time, and the multiple anti-slip teeth 220 on the two clamping surfaces will bite each other, so as to bite off the metal wire and effectively protect the clamp device.
[0049] The elastic component includes two compression springs 300, which are arranged side by side in the conical cavity 110. The two compression springs 300 are respectively connected to the two pliers heads 200 in a one-to-one correspondence, and the compression springs 300 provide elastic preload for the corresponding pliers heads 200 to move forward.
[0050] Specifically, a protrusion 130 is provided at the rear end of the pliers head 200, and the front end of the compression spring 300 is sleeved on the protrusion 130 to prevent the front end of the compression spring 300 from escaping from the protrusion 130 and failing to provide elastic force to the pliers head 200 normally. The rear end of the compression spring 300 is connected to the rear end surface of the conical cavity 110. The rear end of the compression spring 300 can also be sleeved on the corresponding protrusion 130 or directly embedded or bonded to ensure the stability of the compression spring 300.
[0051] The rear end of the clamp body 100 is symmetrically provided with two connecting parts 140, which are integrally formed at the rear end of the clamp body 100, and the end of the connecting part 140 is coaxially provided with a connecting hole 141, and the axial direction of the connecting hole 141 is horizontally arranged along the left and right direction. The two connecting holes 141 can be used to connect other components externally, so as to facilitate the installation of the clamp device.
[0052] When the clamping surfaces of the two pliers heads 200 are in contact with each other, the front ends of the two pliers heads 200 are spliced into an acute-angle structure. Similarly, the two guiding inclined surfaces 111 on both sides of the conical cavity 110 also form an acute-angle gap of the same angle, and the acute-angle structure moves back and forth inside the clamp body 100; the pliers heads 200 move forward by the same displacement, and can generate a greater downward clamping force than the pliers heads 200 with a larger angle. The anti-slip teeth 220 on the two pliers heads 200 can provide more friction, so that the pliers heads 200 can clamp the metal wire firmly.
[0053] In addition, the front inner side surface of the pliers head 200 is provided with an introduction bevel, which is inclined inward from the front to the back, and the two introduction bevels constitute an introduction angle 240. The introduction angle 240 can facilitate the metal wire to smoothly enter the gap between the two clamping surfaces when the gap between the two clamping surfaces is not large. At the same time, the design of the introduction angle 240 also prevents the metal wire from being exposed from the two pliers heads 200 from rubbing against the sharp edge of the front end of the pliers head 200, thereby reducing the risk of the metal wire breaking.
[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
