Description

Technical Field

[0001] The utility model relates to the technical field of line stringing devices for distribution networks, in particular to an anti-slip wire clamp with a branching structure. Background Art

[0002] Wire clamps for distribution networks are key metal accessories used to secure, connect, and protect conductors in power systems. Wire clamps with branching functions play an important role in distributing electrical energy in power grids. Branching mechanisms ensure connectivity stability, preventing the main line from being too tight and damaging the insulation, and preventing the branch line from being too loose and falling off. Therefore, a stable and reliable branching mechanism is particularly important.

[0003] The Chinese invention patent application with publication number CN117458338A discloses a new type of anti-slip wire clamp, in which an oblique wedge groove is opened on the lower pressing surface of the wire clamp base, and a wedge block slider is arranged inside the oblique wedge groove. By applying reverse force, the friction of the contact surface is increased, which not only ensures the compression of the ground wire and the tower wire, but also ensures that the wire is not damaged under tension. It is a wire tightening tool suitable for a variety of wires, which brings great convenience to users. However, the wire clamp does not have a wire splitting function and has poor applicability. In addition, during the clamping process, the force application point of the wire clamp is far away from the overall center of gravity and the force application direction is in the horizontal direction or near the horizontal direction. The horizontal component force is large, which causes the wire clamp to displace horizontally or has a tendency to displace horizontally, thereby increasing the risk of damage to the insulation layer. Utility Model Content

[0004] In response to the problems existing in the prior art, the utility model provides a non-slip wire clamp with a wire dividing structure that is simple in structure, easy to operate, realizes the wire dividing function, and is easy to adjust. During the clamping process, the risk or tendency of the wire clamp to undergo horizontal displacement is reduced, and the risk of damage to the insulation layer is effectively reduced.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: an anti-slip wire clamp with a wire-dividing structure, comprising a base, a first wire clamping plate, a second wire clamping plate and a clamping mechanism; the clamping mechanism comprises a first connecting plate and a linkage structure; the first connecting plate comprises a first end, a second end and a force-applying portion; the first wire clamping plate is arranged between the force-applying portion and the base, and the second wire clamping plate is arranged on the linkage structure; the first end moves along the first direction or the second direction on the base, and when the first end moves along the first direction or the second direction, the second end rotates with the base and the linkage structure along the first axis, and the force-applying portion acts on the first wire clamping plate and the linkage structure respectively, the first direction is an arc direction with the first axis as the axis, and the first direction is opposite to the second direction;

[0006] When the first end moves along the first direction B: the first clamping plate approaches the base under the action of the force-applying portion, and a first clamping space is formed between the first clamping plate and the base, the first clamping space is used for clamping the main line, the second clamping plate approaches the base under the action of the linkage structure, and a second clamping space is formed between the second clamping plate and the base, the second clamping space is used for clamping the branch line, when the first clamping space is formed between the first clamping plate and the base, or when the first clamping space is formed between the first clamping plate and the base and the second clamping space is formed between the second clamping plate and the base When the first end moves along the second direction C: the first wire clamping plate moves away from the base under the action of the force-applying part, and the second wire clamping plate moves away from the base under the action of the linkage structure. When the first wire clamping plate moves away from the base, or when both the first wire clamping plate and the second wire clamping plate move away from the base, the anti-slip wire clamp with a wire splitting structure is in an open state.

[0007] By moving the first end along the first direction B, the first wire clamping space and the second wire clamping space can be formed at the same time, so that the anti-slip wire clamp with a branching structure can reach a clamping state. By moving the first end along the second direction C, the first wire clamping space and the second wire clamping space can be opened, so that the anti-slip wire clamp with a branching structure can reach an open state. The structure is simple and easy to operate. At the same time, the branching function is realized, the application range is increased, and the clamping of different clamping amounts can be achieved by the distance the first end moves along the first direction B, which is convenient for adjustment.

[0008] The first direction B is the arc direction with the first axis as the axis, that is, the force direction during the clamping process is the arc direction with the first axis as the axis. Compared with the prior art, the force is applied in the horizontal direction or the direction close to the horizontal direction, which greatly reduces the horizontal force component, and reduces the risk or tendency of the anti-slip clamp with a branching structure to undergo horizontal displacement, thereby effectively reducing the risk of damage to the insulation layer.

[0009] In some embodiments, the first end is moved along the first direction by applying force to the first end; when the first end moves along the first direction, the first end moves from the first position to the second position, or the first end moves from close to the first position to close to the second position, the first position is higher than the second position, and the clamping process is a process of applying force from a high position to a low position, which facilitates force application.

[0010] In some embodiments, along the horizontal direction, the first position is closer to the center of gravity of the anti-slip clamp with a branching structure than the second position. The force application process of the clamping process is a process in which the force application point approaches the center of gravity along the horizontal direction or the force application point moves near the center of gravity along the horizontal direction. The anti-slip clamp with a branching structure is stable, greatly avoids the risk of flipping and reduces the tendency to flip, thereby further reducing the risk of damage to the insulation layer.

[0011] In some embodiments, the base includes a main clamping seat, the main clamping seat includes a first surface and a second surface, the first surface is opposite to the second surface;

[0012] When the first end moves along the first direction: the first clamping plate approaches the first surface under the action of the force-applying portion, and a first clamping space is formed between the first clamping plate and the first surface, and the second clamping plate approaches the second surface under the action of the linkage structure, and a second clamping space is formed between the second clamping plate and the second surface; when the first end moves along the second direction: the first clamping plate moves away from the first surface under the action of the force-applying portion, and the second clamping plate moves away from the second surface under the action of the linkage structure. The first surface and the second surface opposite to each other on the main clamping seat are selected to correspond to the first clamping plate and the second clamping plate respectively to form the first clamping space and the second clamping space, and when clamping, the stable main clamping seat serves as a partition between the first clamping space and the second clamping space. When in use, the first clamping space is usually on the top and the second clamping space is on the bottom, with a simple structure, stable clamping and good line separation effect.

[0013] In some embodiments, the base further includes a connecting seat, the connecting seat is fixedly connected to the main clamping seat, and a first arc groove and a second arc groove are formed on the connecting seat;

[0014] The first end moves in the first arc groove along the first direction or the second direction;

[0015] The first clamping plate includes a fourth end, and the force applying portion is hingedly connected to the first clamping plate along a second axis;

[0016] When the first end moves along the first direction, the fourth end moves along the fifth direction in the second arc groove;

[0017] When the first end moves along the second direction, the fourth end moves along a sixth direction in the second arc groove.

[0018] In some embodiments, a second wire groove is defined on the second surface, and a fourth wire groove is defined on the surface of the second clamping plate adjacent to the second surface, wherein the second wire groove and the fourth wire groove are parallel to each other; when the first end moves along the first direction, a second wire clamping space is formed between the second wire groove and the fourth wire groove. Since the second wire groove and the fourth wire groove remain parallel to each other during movement of the first end along the first direction or the second direction, during the clamping process, the second wire groove and the fourth wire groove evenly clamp the branch wire from both sides, thereby avoiding damage to the branch wire's outer insulation layer while ensuring a clamping effect to prevent the branch wire from slipping during use.

[0019] In some embodiments, the clamping mechanism further comprises a fastening assembly;

[0020] When the first wire clamping space is formed between the first wire clamping plate and the base, or the second wire clamping space is formed between the second wire clamping plate and the base, the fastening assembly limits the relative position between the first wire clamping plate and the base, and the fastening assembly limits the relative position between the linkage structure and the base.

[0021] In some embodiments, the fastening assembly includes at least a second connecting bolt, which is arranged along the second axis. Because the force-applying portion directly acts on the first clamping plate and the linkage structure to form the first clamping space between the first clamping plate and the base, and the linkage structure to form the second clamping space between the second clamping plate and the base, the second connecting bolt can simultaneously limit the position of the first and second clamping plates, thereby maintaining the clamped state.

[0022] In some embodiments, the connecting seat is provided with a second sliding groove on a side away from the main clamping seat; the main clamping seat includes a third end;

[0023] The second end is respectively engaged with the third end and the second clamping line in rotation along the first axis;

[0024] The linkage structure includes a linkage rod, a first linkage rod, two second linkage rods and a slider;

[0025] The slider is slidably engaged with the second sliding groove;

[0026] One end of the connecting rod is movably connected to the force applying portion, and the other end of the connecting rod is rotatably matched with the slider along the third axis;

[0027] One end of the first connecting rod is hingedly connected to the third end along the first axis, and the other end of the first connecting rod is hingedly connected to the second clamping line along a fourth axis; the two second connecting rods are located on the same side of the first connecting rod;

[0028] One end of the two second connecting rods is hingedly connected to the slider, and the other end of the two second connecting rods is hingedly connected to the second clamping plate, and a parallel four-link structure is formed between the two second connecting rods, the parts where the two second connecting rods and the slider are hinged to each other, and the parts where the two second connecting rods and the second clamping plate are hinged to each other.

[0029] In some embodiments, a strip groove is provided at the end portion of the connecting rod connected to the force-applying portion, and the strip groove is sleeved on the outside of the second connecting bolt, and when the first end moves along the first direction or the second direction, the second connecting bolt slides back and forth along the strip groove, so that no matter how the clamping amount of the first clamping space changes, the clamping of the second clamping space can be adjusted by the position of the second connecting bolt in the strip groove, thereby omitting the additional wire blocking structure, simplifying the structure, and facilitating adjustment.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The utility model can achieve a clamping state or an open state by moving the first end along the first direction or the second direction. It has a simple structure and is easy to operate. At the same time, it realizes the line splitting function, increases the scope of application, and realizes clamping of different line clamping amounts by the distance the first end moves along the first direction, which is easy to adjust and has a wide range of applications.

[0032] 2. Compared with the prior art in which force is applied in a horizontal direction or a direction close to the horizontal direction, the present invention greatly reduces the horizontal force component, thereby reducing the risk or tendency of horizontal displacement of the anti-slip clamp with a branching structure, thereby effectively reducing the risk of damage to the insulation layer.

[0047] To clearly illustrate the technical features of this solution, the following detailed description of the implementation methods of this application will be given in conjunction with the accompanying drawings and examples, so that the implementation process of how this application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of this application and the various features therein can be combined with each other as long as they do not conflict with each other, and the resulting technical solutions are all within the scope of protection of this application.

[0048] Example 1

[0049] See also Figure 3 This embodiment provides an anti-slip wire clamp with a wire splitting structure, including a base 1, a first wire clamping plate 3, a second wire clamping plate 8 and a clamping mechanism; see Figure 1, the clamping mechanism is arranged on the base 1, and the clamping mechanism includes a first connecting plate 2 and a linkage structure 9; the first connecting plate 2 includes a first end 21, a second end 22 and a force-applying portion 23; the first clamping plate 3 is arranged between the force-applying portion 23 and the base 1, the linkage structure 9 is respectively connected to the first connecting plate 2 and the base 1, and the second clamping plate 8 is arranged on the linkage structure 9; the first end 21 moves along the first direction B or the second direction C on the base 1, and when the first end 21 moves along the first direction B or the second direction C, the second end 22 is respectively rotated with the base 1 and the linkage structure 9 along the first axis, and the force-applying portion 23 acts on the first clamping plate 3 and the linkage structure 9, respectively, the first direction B is the direction of an arc with the first axis as the axis, and the first direction B is opposite to the second direction C;

[0050] When the first end 21 moves along the first direction B: the first clamping plate 3 is close to the base 1 under the action of the force-applying portion 23, and a first clamping space is formed between the first clamping plate 3 and the base 1, and the first clamping space is used for clamping the main line. The second clamping plate 8 is close to the base 1 under the action of the linkage structure 9, and a second clamping space is formed between the second clamping plate 8 and the base 1, and the second clamping space is used for clamping the branch line. When the first clamping space is formed between the first clamping plate 3 and the base 1, or when the first clamping space is formed between the first clamping plate 3 and the base 1 and the second clamping space is formed between the second clamping plate 8 and the base 1, there is The anti-slip wire clamp of the line-dividing structure is in a clamping state. Since the first wire clamping space is used for clamping the main line and the second wire clamping space is used for clamping the branch line, the second wire clamping space is usually not used alone, and is only used in conjunction with the first wire clamping space when branching is required; when the first end 21 moves along the second direction C: the first wire clamping plate 3 moves away from the base 1 under the action of the force-applying part 23, and the second wire clamping plate 8 moves away from the base 1 under the action of the linkage structure 9. When the first wire clamping plate 3 moves away from the base 1, or when the first wire clamping plate 3 and the second wire clamping plate 8 are both away from the base 1, the anti-slip wire clamp with the line-dividing structure is in an open state.

[0051] The benefit is that: by moving the first end 21 along the first direction B, the first wire clamping space and the second wire clamping space can be formed at the same time, so that the anti-slip wire clamp with a branching structure can reach a clamping state, and by moving the first end 21 along the second direction C, the first wire clamping space and the second wire clamping space can be opened, so that the anti-slip wire clamp with a branching structure can reach an open state. The structure is simple and the operation is convenient. At the same time, the branching function is realized, the application range is increased, and the clamping of different clamping amounts can be achieved by the distance the first end 21 moves along the first direction B, which is convenient for adjustment.

[0052] It is also beneficial that: the first direction B is the arc direction with the first axis as the axis, that is, the force direction during the clamping process is the arc direction with the first axis as the axis. Compared with the prior art, the force is applied in the horizontal direction or the direction close to the horizontal direction, which greatly reduces the horizontal force component, reduces the risk or tendency of the anti-slip clamp with a branching structure to undergo horizontal displacement, thereby effectively reducing the risk of damage to the insulation layer.

[0053] Preferably, see Figure 1 、 2 3. During the clamping process, the first end 21 is moved along the first direction B by applying force to the first end 21; when the first end 21 moves along the first direction B, the first end 21 moves from the first position to the second position, or the first end 21 moves from close to the first position to close to the second position, and the first position is higher than the second position; similarly, when the first end 21 moves along the second direction C, the first end 21 moves from the second position to the first position, or the first end 21 moves from close to the second position to close to the first position.

[0054] Advantageously, the clamping process is a process of applying force from a high position to a low position, which facilitates force application.

[0055] Taking the new anti-slip wire clamp in the prior art as an example, in which the clamping process is achieved by applying force to the first end 21, the first end 21 is already far away from the overall center of gravity of the wire clamp before clamping. During the clamping process, the force application point moves in the horizontal direction away from the overall center of gravity of the wire clamp. The wire clamp is prone to flipping or has a tendency to flip, thereby increasing the risk of damage to the insulation layer.

[0056] In order to further reduce the operational risk of the insulating layer during the clamping process, the first position is closer to the center of gravity of the anti-slip clamp with a branching structure than the second position in the horizontal direction.

[0057] Beneficially, the force application process of the clamping process is the process of the force application point approaching the center of gravity in the horizontal direction or the movement of the force application point near the center of gravity in the horizontal direction. The anti-slip clamp with a split-line structure is stable, which greatly avoids the risk of flipping and reduces the tendency to flip, thereby further reducing the risk of damage to the insulation layer.

[0058] Furthermore, when the first end 21 moves along the first direction B by applying force to the first end 21, the proportion of the first horizontal force component is greater than the proportion of the second horizontal force component, the proportion of the first horizontal force component is the proportion of the horizontal force component of the force applied when the first end 21 is close to the first position, and the proportion of the second horizontal force component is the proportion of the horizontal force component of the force applied when the first end 21 is close to the second position, that is, the proportion of the first vertical force component is less than the proportion of the second vertical force component, the proportion of the first vertical force component is the proportion of the vertical force component of the force applied when the first end 21 is close to the first position, and the proportion of the second vertical force component is the proportion of the vertical force component of the force applied when the first end 21 is close to the second position.

[0059] What is beneficial is that, since the closer to the clamping state, the greater the risk of damage to the insulation layer caused by the force with a larger proportion of the horizontal component, when the force is applied through the first end 21 during the clamping process, the first end 21 moves along the first direction B. When approaching the clamping state, the direction of the force gradually changes from a large proportion of the horizontal component to a large proportion of the vertical component. When approaching the clamping state, the risk of damage to the insulation layer caused by the force applied by the first end 21 can be further reduced.

[0060] In some embodiments, the base 1 includes a main clamping seat 110, the main clamping seat 110 includes a first surface 117 and a second surface 118, the first surface 117 and the second surface 118 are opposite to each other; the main clamping seat 110 includes a first body 111, the first surface 117 and the second surface 118 are opposite to each other;

[0061] When the first end 21 moves along the first direction B: the first clamping plate 3 approaches the first surface 117 under the action of the force-applying portion 23, and a first clamping space is formed between the first clamping plate 3 and the first surface 117, a first wire groove 112 is provided on the first surface 117, and a third wire groove 31 is provided on the surface of the first clamping plate 3 close to the first surface 117, and anti-slip grooves are provided on the surface of the third wire groove 31. In the clamping state, a first wire clamping space is formed between the first wire groove 112 and the third wire groove 31, and the second clamping plate 8 approaches the second surface 118 under the action of the linkage structure 9, and a second wire clamping space is formed between the second clamping plate 8 and the second surface 118; when the first end 21 moves along the second direction C: the first clamping plate 3 moves away from the first surface 117 under the action of the force-applying portion 23, and the second clamping plate 8 moves away from the second surface 118 under the action of the linkage structure 9.

[0062] It is beneficial to select the first surface 117 and the second surface 118 on the main wire clamping seat 110 that are opposite to each other, corresponding to the first wire clamping plate 3 and the second wire clamping plate 8 respectively to form the first wire clamping space and the second wire clamping space, and when clamping, the stable main wire clamping seat 110 serves as a separator between the first wire clamping space and the second wire clamping space. When in use, the first wire clamping space is usually on the top and the second wire clamping space is on the bottom. The structure is simple, the wire clamping is stable and the wire separation effect is good.

[0063] In some embodiments, the third wire groove 31 is parallel to the first wire groove 112. The third wire groove 31 and the first wire groove 112 are in a parallel state when approaching or moving away from each other, which can increase the use range of the first wire clamping space and enable the first wire clamping space to be applied to different wire quantities.

[0064] See also Figure 3The first biting block 6 is slidably set in the first wire groove 112, and a first slide groove 113 is opened in the first wire groove 112. The first biting block 6 is slidably set in the first slide groove 113. The first slide groove 113 is sloped. During use, when the first end 21 moves along the first direction B during the line clamping process, the first biting block 6 moves from the bottom of the slope to the top of the slope, that is, slides from the deep end to the shallow end in the first slide groove 113 to achieve biting.

[0065] In some embodiments, the base 1 further includes a connecting seat 120, which is fixedly connected to the main clamping seat 110 and has a first arc groove 122 and a second arc groove 123 formed thereon. The connecting seat 120 includes a second body 121, the first arc groove 122 and the second arc groove 123 being formed on the second body 121, and the connecting seat 120 is close to the first surface 117 and away from the second surface 118.

[0066] The first end 21 moves in the first arc groove 122 along the first direction B or the second direction C;

[0067] The first clamping plate 3 includes a fourth end 32, and the force applying portion 23 is hingedly connected to the first clamping plate 3 along the second axis;

[0068] When the first end 21 moves along the first direction B, the fourth end 32 moves along the fifth direction F in the second arc groove 123;

[0069] When the first end 21 moves along the second direction C, the fourth end 32 moves along the sixth direction G in the second arc groove 123 .

[0070] The fourth end 32 slides in cooperation with the second arc groove 123 through the fourth connecting bolt 14 , that is, when the first end 21 moves along the first direction B or the second direction C, the fourth end 32 moves along the fifth direction F or the sixth direction G driven by the fourth connecting bolt 14 .

[0071] In some embodiments, a second wire groove 115 is provided on the second surface 118, and a fourth wire groove 81 is provided on the surface of the second wire clamping plate 8 close to the second surface 118, and the second wire groove 115 and the fourth wire groove 81 are parallel to each other; when the first end 21 moves along the first direction B: a second wire clamping space is formed between the second wire groove 115 and the fourth wire groove 81, and anti-slip grooves are respectively provided on the surfaces of the second wire groove 115 and the fourth wire groove 81. Since the second wire groove 115 and the fourth wire groove 81 always remain parallel to each other during the movement of the first end 21 along the first direction B or the second direction C, that is, during the clamping process, the second wire groove 115 and the fourth wire groove 81 evenly clamp the branch line when they clamp the branch line from both sides of the branch line, thereby avoiding damage to the surface insulation layer of the branch line, while ensuring the clamping effect to prevent the branch line from slipping during use.

[0072] In some of these embodiments, the clamping mechanism further comprises a fastening assembly;

[0073] When a first wire clamping space is formed between the first wire clamping plate 3 and the base 1, or a second wire clamping space is formed between the second wire clamping plate 8 and the base 1, the fastening assembly limits the relative position between the first wire clamping plate 3 and the base 1, and the fastening assembly limits the relative position between the linkage structure 9 and the base 1, that is, when the first wire clamping space is formed, or the first wire clamping space and the second wire clamping space are formed at the same time, the clamping state of the anti-slip wire clamp with a branching structure is maintained by the fastening assembly.

[0074] In some embodiments, the fastening assembly includes at least a second connecting bolt 12 , which is disposed along a second axis, and the second axis is a hinged connection between the force-applying portion 23 and the first clamping plate 3 .

[0075] The benefit is that: since the force-applying part 23 directly acts on the first clamping plate 3 and the linkage structure 9, a first clamping space is formed between the first clamping plate 3 and the base 1, and a second clamping space is formed between the second clamping plate 8 and the base 1 under the action of the linkage structure, the first clamping plate 3 and the second clamping plate 8 can be limited at the same time by the second connecting bolt 12, thereby maintaining the clamping state.

[0076] The first connecting plate 2 has a first end 21 at one end and a second end 22 at the other end. The middle portion of the first connecting plate 2 is a force-applying portion 23.

Preferably, the bolt head and nut of the third connecting bolt 13 are axially lengthened to facilitate force application. Figure 3 、 4 The force can be applied by hooking the bolt head and the nut with two fingers respectively to apply force to the third connecting bolt 13, thereby indirectly applying force to the first end 21; the third connecting bolt 13 moves in the first arc groove 122 along the first direction B or the second direction C, driving the first end 21 to move along the first direction B or the second direction C;

[0078] The benefit is that the third connecting bolt 13 is convenient for applying force with fingers by setting an axially extended bolt head and nut, and after installation, the anti-slip wire clamp with a branching structure has no redundant force-applying components during use, reducing the overall number of contact points, thereby improving service life.

[0079] See also Figure 4In addition to applying force with fingers, force can also be applied through the pull rod 20; the pull rod 20 is U-shaped, and the two sides of the U-shaped open end are bent into hooks. When in use, the hooks on both sides of the open end of the U-shaped pull rod 20 hook the bolt head and the nut respectively, and force is applied to the closed end of the U to achieve force on the third connecting bolt 13, which is convenient for force application. Similarly, after installation, the anti-slip wire clamp with a branching structure has no redundant force-applying components during use, reducing the number of overall contact points, thereby increasing service life.

[0080] Preferably, the fastening assembly also includes a first connecting bolt 11, a third connecting bolt 13 and a fourth connecting bolt 14. When the anti-slip wire clamp with a branching structure is in a clamping state, the first connecting bolt 11, the second connecting bolt 12, the third connecting bolt 13 and the fourth connecting bolt 14 are tightened respectively to ensure the limiting effect.

[0081] Preferably, the inner side surface of the connecting seat 120 is fixedly connected to the main wire clamping seat 110; one side surface of the first wire clamping plate 3 is in contact with the inner side surface of the connecting seat 120, and when the wire is clamped in the first wire clamping space, the inner side surface of the connecting seat 120 facing the side corresponding to the first wire clamping space has a wire blocking function, and the other side surface of the first wire clamping plate 3 is movably connected to the wire blocking plate 7 between the main wire clamping seat 110, and the wire blocking plate 7 includes a wire blocking portion 73; when the first wire clamping plate 3 is away from the main wire clamping seat 110, the wire blocking portion 73 is located in the third position, and when the wire blocking portion 73 is located in the third position, the wire blocking plate 7 is located as a whole at the first wire clamping plate 3 or the wire blocking plate 7 is located as a whole at the main wire clamping seat 110; that is, when the wire blocking portion 73 is in the third position, the interval between the first wire clamping plate 3 and the main wire clamping seat 110 is opened, so that the main line is conveniently fed into the first wire groove 112 and the third wire groove 31;

[0082] When the first wire clamping plate 3 is close to the main wire clamping seat 110 to form a first wire clamping space, the wire blocking portion 73 is located at the fourth position. When the wire blocking portion 73 is located at the fourth position, the wire blocking portion 73 is located between the first wire clamping plate 3 and the main wire clamping seat 110, realizing the wire blocking function of the first wire clamping space.

[0083] In some preferred embodiments, one end of the wire blocking plate 7 is rotatably engaged with the second shaft, and the other end of the wire blocking plate 7 is provided with a wire blocking portion 73. When the first wire clamping plate 3 is away from the main wire clamping seat 110, the wire blocking plate 7 rotates along the third direction D until the wire blocking portion 73 is located in a third position. When the first wire clamping plate 3 approaches the main wire clamping seat 110 to form a first wire clamping space, the wire blocking plate 7 rotates along the fourth direction E until the wire blocking portion 73 is located in a fourth position. The wire blocking portion 73 is moved between the third position and the fourth position by rotation, thereby realizing the overall integration of the anti-slip wire clamp.

[0084] In some preferred embodiments, the wire baffle 7 also includes a hanging ear 72, which is rotated with the second shaft. When the wire blocking part 73 is in the fourth position, the hanging ear 72 is clamped on the fourth connecting bolt 14, effectively utilizing the connection part between the first wire clamping plate 3 and the base 1. At the same time, the connection between the hanging ear 72 and the fourth connecting bolt 14 can ensure the stability of the wire baffle 7 during use.

[0085] Preferably, a toggle portion 71 is provided on the wire baffle 7 , and the toggle portion 71 is located close to the hanging ear 72 , so as to facilitate the rotation or toggle of the wire baffle 7 .

When the first end 21 moves along the first direction B or the second direction C, the first connecting plate 2 drives the slider 94 to slide in the second slide groove 124 through the connecting rod 91. Under the restriction of the parallel four-link structure and the first connecting rod 92, the fourth wire groove 81 and the second wire groove 115 approach or move away from each other.

[0093] Advantageously, the linkage structure 9 can be provided to enable the second clamping plate 8 to move closer to or farther from the base 1 through the movement of the first connecting plate 2, without the need for an additional clamping structure, and thus the operation is convenient.

[0095] The benefit is that: by setting the strip groove 911, when the first wire clamping space and the second wire clamping space are used at the same time, no matter how the clamping amount of the first wire clamping space changes, the clamping of the second wire clamping space can be adjusted by the position of the second connecting bolt 12 in the strip groove 911, omitting the additional wire blocking structure, simplifying the structure, and facilitating adjustment.

[0096] See also Figure 5 In some embodiments, the second slide groove 124 passes through the end surface of the connecting seat 120 near the third end 116, and a limiting groove 125 is formed on both sides of the second slide groove 124 away from the third end 116. The slide groove auxiliary member 10 can be detachably connected in the second slide groove 124 to facilitate the installation of the slider 94;

The slider connecting part 942 passes between the two blocking bars 102, and the two blocking bars 102 are installed in the limiting groove 125 away from the ends of the blocking block 101. The blocking block 101 is located at the end of the second slide groove 124 passing through the second main body 121, which is used to prevent the slider 94 from slipping and facilitate installation; the second slide groove 124 passes through the end of the second main body 121 to provide a first threaded hole 126, and a connecting through hole 103 is provided on the blocking block 101, and the through hole 103 and the first threaded hole 126 are respectively connected by the seventh connecting bolt 17 to achieve the fixation of the blocking block 101; a second threaded hole 127 is provided near the limiting groove 125, and the six connecting bolt 16 is used to limit the two blocking bars 102.

[0100] Example 2

[0101] In order to facilitate inspection and maintenance, it is often necessary to install a grounding device on the wire clamp to ensure the safety of maintenance personnel. However, the additional grounding device increases additional costs and is limited by the stability of the installation, which can easily cause safety hazards.

[0102] In order to improve the performance of the anti-slip wire clamp with a split wire structure, based on Example 1, other aspects are the same as Example 1, and the differences from Example 1 are as follows:

[0103] See also Figure 7-11 The anti-slip wire clamp with a split wire structure also includes a grounding ring 5 and a second connecting plate 4. In view of the angle of the accompanying drawing, the second connecting plate 4 is Figure 8 Not shown in the figure, the second connecting plate 4 is used to install the grounding ring 5 on the base 1.

[0104] Advantageously, the provision of the grounding ring 5 can avoid additional costs during maintenance, and the grounding ring 5 integrated with the wire clamp has low potential safety hazards and is stable in use.

[0105] The first wire clamping space and the second wire clamping space are located on the same side of the connecting base 120, and the grounding ring 5 is located on the side of the connecting base 120 away from the first wire clamping space to prevent the grounding ring 5 from interfering with the wire clamping when clamping or in use, thereby affecting the use effect;

[0106] The grounding ring 5 is mounted on the connecting base 120 via the second connecting plate 4;

[0107] See also Figure 12 、 13, a third arc groove 128 is also provided on the connecting seat 120. The center of the second arc groove 123 is the first center of the circle, and the center of the third arc groove 128 is the second center of the circle. When the first center of the circle is translated to the second center of the circle along the seventh direction, the second arc groove 123 and the third arc groove 128 coincide with each other. Strictly speaking, the seventh direction is the horizontal direction when the anti-slip clamp with a split line structure is in use. The second connecting plate 4 is installed between the second arc groove 123 and the third arc groove 128. Preferably, the third arc groove 128 is located on one side of the second arc groove 123, and the first axis is located on the other side of the second arc groove 123. During the clamping or opening process, the interference between the grounding ring 5 and the clamping mechanism is avoided or reduced. At the same time, through reasonable weight distribution, the process of clamping, the process of the force application point approaching the center of gravity in the horizontal direction, or the movement of the force application point near the center of gravity in the horizontal direction is further ensured.

[0108] See also Figure 11 The second connecting plate 4 is T-shaped and includes a fifth end 41, a sixth end 42, and a seventh end 43. One end of the horizontal portion of the T-shape is the fifth end 41, the other end of the horizontal portion of the T-shape is the sixth end 42, and the outer end of the vertical portion of the T-shape is the seventh end 43. The fifth end 41 is connected to the connecting seat 120 and the first clamping plate 3 at the second arc groove 123, respectively. The sixth end 42 is connected to the connecting seat 120 at the third arc groove 128. The grounding ring 5 is installed at the seventh end 43.

[0109] During the movement of the first end 21 along the first direction B, the fourth end 32 moves along the fifth direction F in the second circular arc groove 123, driving the fifth end 41 to move along the fifth direction F along the second circular arc groove 123, that is, the second connecting plate 4 moves, and at this time the sixth end 42 moves along the third circular arc groove 128; when the first end 21 moves along the second direction C, the fourth end 32 moves along the sixth direction G in the second circular arc groove 123, driving the fifth end 41 to move along the sixth direction G along the second circular arc groove 123, that is, the second connecting plate 4 moves, and at this time the sixth end 42 moves along the third circular arc groove 128.

[0110] Advantageously, by arranging the second connecting plate 4 for mounting the grounding ring 5 between the second arc groove 123 and the third arc groove 128, when the second connecting plate 4 is successfully installed, no matter how the first end 21 moves during the clamping process, the plane where the T-shape is located will definitely not flip, thereby ensuring the stable installation of the grounding ring 5.

[0111] That is, during the process of the fourth end 32 moving along the fifth direction F in the second arc groove 123,

[0112] The fifth end 41 is mounted on the second arc groove 123 via the fourth connecting bolt 14 , the sixth end 42 is mounted on the third arc groove 128 via the fifth connecting bolt 15 , and the grounding ring 5 is mounted on the seventh end 43 via the eighth connecting bolt 18 ;

[0113] Preferably, the grounding ring 5 is U-shaped, and the open end of the U-shaped grounding ring 5 is sleeved on both sides of the seventh end 43. During installation, the grounding ring 5 is connected to the seventh end 43 through the eighth connecting bolt 18.

[0114] Advantageously, the U-shaped grounding ring 5 is provided, which has a simple structure and is convenient for disassembly, assembly and maintenance.

[0115] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
