Description

Technical Field

[0001] The utility model relates to a clamp structure, and more specifically, to a network clamp. Background Art

[0002] A network clamp is a commonly used tool for wire cutting and wire stripping, which is widely used in daily life. In the existing network clamp, the blade is very unstable during the wire cutting process. After long-term use, when the blade is subjected to force, it is easy to deflect and tilt around the positioning screw, which limits the wire cutting function of the network clamp. Although the blade can be manually adjusted back to its original position, the operation is troublesome and cumbersome, greatly reducing the user experience.

[0003] For example: Chinese Patent Publication No. CN206595647U, Publication Date: October 27, 2017, the name of the utility model is a new type of multi-functional network cable pliers. This application discloses a network cable pliers structure, which includes an upper main body and a lower main body on the main body. The upper main body and the lower main body are movably connected by a first pin shaft. The main body is provided with a wire stripping port, a wire cutting port and a wire pressing port. The upper main body is connected to the upper handle. This solution can achieve multiple functions such as wire stripping, wire cutting and wire pressing. However, in this solution, the blade at the wire cutting port is only fixed to the main body by a positioning shaft. When the blade is stressed, it is easy to deflect around the positioning shaft, resulting in the blade being unusable. Summary of the Utility Model

[0004] The utility model overcomes the problem that the blade of the network clamp is prone to deflection and failure, and provides a network clamp. This solution limits the rotational freedom of the blade and enhances the stability of the blade during operation, effectively preventing the problem of deflection and tilt of the blade in the network clamp.

[0005] To solve the above technical problems, the utility model adopts the following technical solution: A network clamp includes a blade, the blade is arranged on the pliers mouth main body, and further includes a Z-shaped limiting member. The limiting member is provided with a first abutting edge and a second abutting edge. The blade is arranged on the limiting member and is aligned with the first abutting edge, and the second abutting edge is arranged on the pliers mouth main body and is aligned with the inner side of the pliers mouth. In this solution, the limiting member is mainly used to limit the blade. The first abutting edge can abut against the back of the blade. When the blade tip is stressed, the whole back of the blade will press tightly against the first abutting edge, and the second abutting edge will also press tightly against the inner side of the pliers mouth main body when the blade is stressed. The deflection problem of the blade is restricted by the two abutting edges. At the same time, since the back of the blade abuts against the first abutting edge, the stability and working strength of the blade are improved, and the service life of the network clamp is greatly increased.

[0006] Preferably, a first positioning post is further provided on the limiting member. The first positioning post is arranged on the side where the first abutting edge is located, and a groove body adapted to the first positioning post is provided on the blade. The first positioning post is used for initially positioning the blade. The groove bodies on the blade are arranged on both sides. After the groove bodies and the first positioning post are matched, the initial positioning of the blade and the limiting member is completed, which is more conducive to the assembly of the blade. In addition, the limiting effect of the blade can also be enhanced.

[0007] Preferably, a second positioning post is further provided on the limiting member. The second positioning post is arranged on the side where the second abutting edge is located, and a positioning hole adapted to the second positioning post is provided on the jaw body. The second positioning post is used for initially positioning the limiting member. The positioning hole on the jaw body can be matched with the second positioning post to realize the initial positioning of the limiting member on the jaw body, which is beneficial to the installation of the limiting member and the blade on the jaw body. In addition, the limiting effect of the limiting member can also be enhanced.

[0008] Preferably, one end of the blade abuts against the first abutting edge, and the other end of the blade extends outside the limiting member. The back structure of the blade abuts against the first abutting edge, while the cutting head structure needs to extend outside the limiting member to play the cutting role of the cutting head and avoid the limiting member interfering with the working area of the cutting head.

[0009] Preferably, there are two jaw bodies. A locking structure is provided on one of the jaw bodies, and a buckle groove adapted to the lock is provided on the other. The two jaw bodies are in a rotational connection relationship. When the network pliers are not in use, the network pliers need to be stored to protect the internal structure of the network pliers. The two jaw bodies of the network pliers can be locked together through the lock to prevent the jaws from opening and exposing the internal structure to the outside, resulting in the internal structure being easily damaged. When the network pliers need to be used, just open the lock.

[0010] Preferably, the lock is rotationally connected to the jaw body, and a barb is provided on the lock. The lock and the jaw body are arranged in a rotational connection. When the network pliers need to be used, in order to avoid the lock interfering with the jaw position, the lock can be rotated to a position collinear with the handle; when the network pliers are not in use, the lock can be rotated to the locking position again; the barb on the lock can hook the buckle groove on the other jaw body, making the two jaw bodies locked more firmly and not easily separated.

[0011] Preferably, a positioning member is further provided on the jaw body. One end of the positioning member is fixed to one of the jaw bodies, and the other end of the positioning member is inserted and engaged with the other jaw body. The positioning member is mainly used to limit the problem of misalignment of the two jaw bodies. When the network pliers are stored, the two jaw bodies may not be on the same plane due to the external environment, which may ultimately cause the rotation pin shafts of the two jaw bodies to become loose and the performance of the jaw bodies to deteriorate. One end of the positioning member can be fixed to one of the jaw bodies, and the other end can be inserted tightly into the other jaw body. Thus, through the action of the positioning member, the two jaw bodies can be kept on the same plane.

[0012] Preferably, the positioning member includes two positioning pieces that can be respectively inserted and engaged with the two jaw bodies. Two positioning pieces can also be provided on the positioning member. By inserting and tightening the two jaw bodies respectively with the two positioning pieces, the two jaw bodies can also be located on the same plane, avoiding the occurrence of misalignment.

[0013] Preferably, an elastic member is further provided between the two jaw bodies. The provision of the elastic member between the two jaw bodies is beneficial for the network pliers to be used more labor-saving. The elastic member can push the two jaw bodies apart to an open state, and the operator only needs to apply a pressing force to close the jaws.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) It can effectively prevent the blade on the jaw from deflecting during the working process and improve the stability of the blade at the same time; (2) The blade has a better positioning effect and the assembly is simpler and more convenient; (3) A lock structure is provided, which can better store the network pliers and reduce the storage space of the network pliers; (4) It can effectively prevent the misalignment phenomenon of the network pliers and ensure good performance of the network pliers.

Specific embodiments

[0024] The technical solution of the present utility model will be further specifically described below through specific embodiments and in conjunction with the drawings.

[0025] Embodiment 1: As Figures 1 to 3 shown, a network plier includes two plier arms 2 which are rotatably connected between them. The part between the rotation axes of the two plier arms 2 is the jaw body part, and a jaw 4 is formed between the two jaw bodies. The jaw 4 can be used for operations such as wire cutting, wire stripping, and wire pressing, and corresponding wire cutting openings, wire stripping openings and other structures are provided. And the wire cutting opening and the wire stripping opening are usually provided with a blade 1 structure for wire cutting and wire stripping work. The blade 1 is arranged on one of the jaw bodies, defined as the first jaw body 21, and the other jaw body is defined as the second jaw body 22. In this embodiment, the blade 1 is arranged on the first jaw body 21.

[0026] Specifically, a limiting member 3 is further arranged between the blade 1 and the first jaw body 21. As Figure 2 and Figure 3 shown, the limiting member 3 is a Z-shaped structure. At both ends of the limiting member 3 are the first abutting edge 31 and the second abutting edge 32 respectively. Among them, the first abutting edge 31 and the second abutting edge 32 are respectively arranged on the opposite sides of the limiting member 3 and are perpendicular to the main surface of the limiting member 3. The back part of the blade 1 is arranged on the first abutting edge 31 and is tightly attached and aligned with the first abutting edge 31, and the second abutting edge 32 is tightly attached and aligned with the inner side of the first jaw body 21. A fixing hole is arranged on the blade 1, the limiting member 3 and the first jaw body 21, and the blade 1, the limiting member 3 and the first jaw body 21 can be fixed together by fastening members such as screws.

[0027] When the cutting head part (the working end of the blade) of the blade 1 is stressed, if the blade 1 has a tendency to rotate around its fastener, the back part of the blade 1 will exert a squeezing effect on the first abutting edge 31 of the limiting member 3, thereby transmitting the force to the limiting member 3, making the limiting member 3 also have a tendency to rotate. The second abutting edge 32 on the limiting member 3 is in contact with the inner side edge of the first jaw body 21, and the first jaw body 21 will restrict the rotation of the limiting member 3, so that the blade 1 cannot deflect either, thus ensuring that the blade 1 can work normally and improving the stability of the blade 1.

[0028] A first positioning post 33 is also provided on the limiting member 3. The first positioning post 33 is arranged on the side where the first abutting edge 31 is located, and the first positioning post 33 is arranged at the middle position of the side of the limiting member 3. A groove body 11 structure adapted to the first positioning post 33 is arranged at the middle side position of the blade 1. Before the blade 1 and the limiting member 3 are fixed together, preliminary positioning can be realized through the first positioning post 33 and the groove body 11 structure. Specifically, the blade 1 is first abutted against the first abutting edge 31, and then the blade 1 is pushed along the first abutting edge 31 towards the position where the first positioning post 33 is located, so that the groove body 11 and the first positioning post 33 are engaged. At this time, the fixing holes on the blade 1 and the fixing holes on the limiting member 3 can be just aligned, which is beneficial to the subsequent installation of the blade 1 and the limiting member 3. It should be noted that two groove body 11 structures are provided and are respectively located on both sides of the blade 1, so that the blade 1 can be engaged with the limiting member 3 whether it is on the front or the back.

[0029] A second positioning post 34 is also provided on the limiting member 3. The second positioning post 34 is arranged on the side opposite to the position where the first positioning post 33 is located. A positioning hole (not shown in the figure) adapted to the second positioning post 34 is arranged on the first jaw body 21. Through the cooperation of the second positioning post 34 and the positioning hole on the first jaw body 21, preliminary positioning of the limiting member 3 and the first jaw body 21 can be realized. And when the second positioning post 34 and the positioning hole on the first jaw body 21 are engaged, the fixing holes on the blade 1, the fixing holes on the limiting member 3 and the fixing holes on the first jaw body 21 can be aligned together, which is beneficial to the assembly work of the blade 1, the limiting member 3 and the first jaw body 21.

[0030] It should be noted that both the first positioning post 33 and the second positioning post 34 are smooth column structures. The first positioning post 33 and the second positioning post 34 may not be fixedly connected to the blade 1 or the first jaw body 21. After the blade 1 is worn, it is beneficial to replace the blade 1.

[0031] The blade 1 includes two ends. One end is the working end, which is the cutter head structure, and the other end is the limiting end, which is the back of the blade structure. The back of the blade abuts against the first abutting edge 31, while the cutter head protrudes outside the limiting member 3, so that the cutter head can be exposed from the limiting member 3 and the first jaw body 21, ensuring that the cutter head can play a cutting role and preventing the limiting member 3 or the first jaw body 21 from interfering with the working area of the cutter head.

[0032] Embodiment 2: As Figures 1 to 8 shown, a network pliers includes two plier arms 2, which are rotatably connected between them. The area between the rotation axes of the two plier arms 2 is the jaw body part, and a jaw 4 is formed between the two jaw bodies. The jaw 4 can be used for operations such as wire cutting, wire stripping, and wire pressing, and corresponding wire cutting openings, wire stripping openings and other structures are provided. The wire cutting opening and the wire stripping opening are usually provided with a blade 1 structure for wire cutting and wire stripping work. The blade 1 is arranged on one of the jaw bodies, defined as the first jaw body 21, and the other jaw body is defined as the second jaw body 22. In this embodiment, the blade 1 is arranged on the first jaw body 21.

[0033] Specifically, a limiting member 3 is further arranged between the blade 1 and the first jaw body 21. As Figure 2 and Figure 3 shown, the limiting member 3 is a Z-shaped structure. At both ends of the limiting member 3 are the first abutting edge 31 and the second abutting edge 32 respectively. Among them, the first abutting edge 31 and the second abutting edge 32 are respectively arranged on opposite sides of the limiting member 3 and are perpendicular to the main surface of the limiting member 3. The back part of the blade 1 is arranged on the first abutting edge 31 and is closely aligned with the first abutting edge 31, and the second abutting edge 32 is closely aligned with the inner side of the first jaw body 21. A fixing hole is provided on the blade 1, the limiting member 3 and the first jaw body 21, and the blade 1, the limiting member 3 and the first jaw body 21 can be fixed together by fasteners such as screws.

[0034] When the cutter head part (the working end of the blade) of the blade 1 is stressed, if the blade 1 has a tendency to rotate around its fastener, the back part of the blade 1 will exert a squeezing effect on the first abutting edge 31 of the limiting member 3, thereby transmitting the force to the limiting member 3, making the limiting member 3 also have a tendency to rotate. And the second abutting edge 32 on the limiting member 3 is tightly attached to the inner side edge of the first jaw body 21, and the first jaw body 21 will limit the rotation of the limiting member 3, so that the blade 1 cannot deflect either, thus ensuring that the blade 1 can work normally and improving the stability of the blade 1.

[0035] A first positioning post 33 is further provided on the limiting member 3. The first positioning post 33 is arranged at a position on the side where the first abutting edge 31 is located, and the first positioning post 33 is arranged at the middle position of the side of the limiting member 3. A groove body 11 structure adapted to the first positioning post 33 is arranged at the middle side position of the blade 1. Before the blade 1 and the limiting member 3 are fixed together, preliminary positioning can be achieved through the first positioning post 33 and the groove body 11 structure. Specifically, the blade 1 is first abutted against the first abutting edge 31, and then the blade 1 is pushed along the first abutting edge 31 towards the position where the first positioning post 33 is located, so that the groove body 11 and the first positioning post 33 are engaged. At this time, the fixing holes on the blade 1 and the fixing holes on the limiting member 3 can be just aligned, which is beneficial to the subsequent installation of the blade 1 and the limiting member 3. It should be noted that two groove body 11 structures are provided and are respectively located on both sides of the blade 1, so that the blade 1 can be fitted on the limiting member 3 regardless of whether it is on the front or the back.

[0036] A second positioning post 34 is further provided on the limiting member 3. The second positioning post 34 is arranged on the side opposite to the position where the first positioning post 33 is located. A positioning hole (not shown in the figure) adapted to the second positioning post 34 is arranged on the first jaw body 21. Through the cooperation of the second positioning post 34 and the positioning hole on the first jaw body 21, preliminary positioning of the limiting member 3 and the first jaw body 21 can be achieved. And after the second positioning post 34 and the positioning hole on the first jaw body 21 are engaged, the fixing holes on the blade 1, the fixing holes on the limiting member 3, and the fixing holes on the first jaw body 21 can be aligned together, so that it is beneficial to the assembly work of the blade 1, the limiting member 3, and the first jaw body 21.

[0037] It should be noted that both the first positioning post 33 and the second positioning post 34 are smooth column structures, and the first positioning post 33 and the second positioning post 34 may not be fixedly connected to the blade 1 or the first jaw body 21. Therefore, after the blade 1 is worn, it is beneficial to replace the blade 1.

[0038] The blade 1 includes two ends. One end is the working end, which is a cutter head structure, and the other end is the limiting end, which is a cutter back structure. The cutter back abuts against the first abutting edge 31, and the cutter head protrudes outside the limiting member 3, so that the cutter head can be exposed from the limiting member 3 and the first jaw body 21, thereby ensuring that the cutter head plays a cutting role and preventing the limiting member 3 or the first jaw body 21 from interfering with the working area of the cutter head.

[0039] A lock catch 5 structure is further provided on the first jaw body 21. The lock catch 5 is an elastic sheet structure, such as Figure 7 or Figure 8As shown, one end of the elastic sheet is relatively flat, and at this flat end, it is rotatably connected to the first jaw body 21 through a positioning pin. The other end of the elastic sheet bends towards the outside of the first jaw body 21, and a barb 51 structure is also provided at this bent end. A buckle groove 6 structure is provided on the second jaw body 22, and the size of the notch of the buckle groove 6 is adapted to the size of the barb 51.

[0040] An elastic member 8 is also provided between the first jaw body 21 and the second jaw body 22. The elastic member 8 is a spring structure. In the normal state, the elastic member 8 will keep the first jaw body 21 and the second jaw body 22 open to a certain extent, which is convenient for the staff to use. At the same time, the elastic member 8 can also cooperate with the locking function of the lock 5 structure.

[0041] Specifically, when the network pliers are used up and need to be stored, at this time, press the first jaw body 21 and the second jaw body 22 together, then rotate the lock 5 structure so that the barb 51 of the lock 5 structure corresponds to the position of the buckle groove 6 on the second jaw body 22, and then press the bent end of the lock 5 structure to press the barb 51 into the inside of the buckle groove 6. Then release the first jaw body 21 and the second jaw body 22. Under the action of the elastic member 8, there is a tendency for the first jaw body 21 and the second jaw body 22 to open. At this time, the barb 51 can hook the groove wall of the buckle groove 6, so that the first jaw body 21 and the second jaw body 22 are locked together, reducing the storage space of the network pliers. When the network pliers need to be used, only need to press the first jaw body 21 and the second jaw body 22 close to each other. At this time, the barb 51 will disengage from the position of the buckle groove 6. Under the action of the self-elastic force of the lock 5, its bent end will drive the barb 51 to pop out, thus releasing the limiting effect between the first jaw body 21 and the second jaw body 22; and in order to prevent the lock 5 structure from interfering with the working area of the jaw 4, the lock 5 structure can also be rotated to a position parallel to the first jaw body 21.

[0042] It should be noted that in this embodiment, the lock 5 is provided on the first jaw body 21, and the buckle groove 6 is provided on the second jaw body 22. In actual applications, the lock 5 can also be provided on the second jaw body 22, and the buckle groove 6 is provided on the first jaw body 21.

[0043] A positioning member 7 is also provided on the first jaw body 21. The positioning member 7 is an overall L-shaped structure, such as Figure 4 and Figure 5As shown, one end of the positioning member 7 is a fixed portion 72, which is fixed on the first jaw body 21, and the other end is a positioning piece 71 located between the first jaw body 21 and the second jaw body 22. Among them, both the first jaw body 21 and the second jaw body 22 are composed of two parallel plate structures, so there is a gap inside the first jaw body 21 and there is also a gap inside the second jaw body 22. When the first jaw body 21 and the second jaw body 22 are pressed together, the positioning piece 71 on the positioning member will be inserted into the gap between the second jaw bodies 22. Through the action of the positioning member 7, the positioning piece 71 can ensure that the first jaw body 21 and the second jaw body 22 are in the same plane, preventing the two from being misaligned and damaging the performance of their rotating shafts.

[0044] Similarly, the whole positioning member 7 can also be a T-shaped structure, as Figure 6 shown. The positioning member 7 also has a fixed portion 72. There are two positioning pieces 71 on both sides of the fixed portion 72. The two positioning pieces 71 can be respectively inserted into the gap inside the first jaw body 21 and the gap inside the second jaw body 22, so as to ensure that the first jaw body 21 and the second jaw body 22 are in the same plane. And compared with the L-shaped positioning member structure, the T-shaped positioning member has higher stability. Similarly, the positioning member 7 can be arranged on the first jaw body 21 or on the second jaw body 22. In this embodiment, arranging the positioning member 7 on the first jaw body 21 is just one of the arrangement methods.
