Description

Technical Field

[0001] The utility model relates to the technical field of electric power fittings, in particular to a mortise and tenon combined type wire clamp. Background Technique

[0002] As an indispensable important component in the power system, the electric power fitting wire clamp plays an important role in aspects such as fixing, connecting and transmitting force of the wire. With the continuous development and progress of electric power technology, the types and performances of electric power fitting wire clamps are also constantly updated and improved.

[0003] In the existing conductor strain wire clamp products, in order to facilitate wire installation, an open-type wire clamp body and a two-half combined inner insulating sleeve are mostly used. During application, during the process of tightening after wire installation, there are only two upper and lower gripping dimensions, and the opening part of the open-type wire clamp body cannot provide a closed-loop gripping force to the inner insulating sleeve, so it is not easy to reach the standard gripping force, and it is also easy to damage the insulating skin wrapped around the wire.

[0004] Therefore, we propose a mortise and tenon combined type wire clamp to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a mortise and tenon combined type wire clamp.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A mortise and tenon combined type wire clamp includes a wire clamp body. The wire clamp body includes two conical semi-cylinders. T-shaped mortise and tenon structures that can be engaged with each other are respectively arranged on both sides of the two conical semi-cylinders. The two conical semi-cylinders are merged left and right in a staggered manner through a plurality of T-shaped mortise and tenon structures. The two conical semi-cylinders can be merged to form a conical cylinder, and an inner sleeve mechanism is arranged in a matching manner inside the conical cylinder.

[0008] Preferably, the thickness of the conical semi-cylinder is less than the thickness of the T-shaped mortise and tenon structure.

[0009] Preferably, the inner sleeve mechanism includes a plurality of inner wedge combination units. Corresponding convex structures and groove structures are respectively arranged on the left and right of each inner wedge combination unit. The plurality of inner wedge combination units can be assembled and spliced with each other through the corresponding convex structures and groove structures, and are spliced to form a hollow cone with a set gap.

[0010] Preferably, the hollow cone formed by splicing a plurality of the inner wedge combination units can be coaxially inserted into the conical cylinder formed by merging two conical semi-cylinders. The outer side of the hollow cone is attached to the inner sides of the two conical semi-cylinders, and the inside of the hollow cone is used for passing the wire. A spiral convex structure is arranged on the inner side surface of the hollow cone.

[0011] Preferably, a number of reserved slots are provided on one side of the inner wedge combination unit that fits the conical semi-cylinder. The reserved slots are arranged perpendicular to the direction of the wire. Two or more inner wedge combination units can be assembled through spring hooks, and both ends of the spring hooks can be inserted and matched with the corresponding two reserved slots.

[0012] Preferably, pull plates are rotatably installed on the sides of both conical semi-cylinders, and a number of mounting holes are provided at one end of each pull plate away from the conical semi-cylinder.

[0013] Preferably, a clip is installed between one end of each of the two pull plates away from the conical semi-cylinder. The clip is in the shape of a triangular plate, and two circular wire tightener hanging holes are provided on the triangular plate.

[0014] Preferably, the wire clamp body further includes two polygonal conical cylinders.

[0028] Embodiment 1

[0029] Referring to Figures 1-6 , a mortise and tenon combined type line clamp includes a line clamp body 1. The line clamp body 1 includes two conical semi-cylinders 2. On both sides of the two conical semi-cylinders 2, there are respectively provided T-shaped mortise and tenon structures 3 that can be engaged with each other, that is, the T-shaped mortise and tenon structures 3 on both sides of the two conical semi-cylinders 2 can be fitted and arranged. The two conical semi-cylinders 2 are merged left and right through a plurality of T-shaped mortise and tenon structures 3, and the two conical semi-cylinders 2 can be merged to form a conical cylinder, and an inner sleeve mechanism is matched and arranged inside the conical cylinder.

[0030] For the above example, those skilled in the art should know that when implementing the above technical solution, the size specifications of the conical semi-cylinder 2 are not limited to a single specification form, and the conical semi-cylinder 2 can be preset with a variety of size specifications according to the use requirements.

[0031] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to using two conical semi-cylinders 2 in combination. It can also be composed of 4 quarter-conical parts, or even more combinations of 2n conical parts.

[0032] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the T-shaped mortise and tenon structure 3, i.e., the mortise and tenon structure, is not limited to the T shape in terms of its shape. This mortise and tenon structure can also be a cuboid structure, a trapezoid structure, a triangular structure, a cylindrical structure, an elliptical structure, a conical structure, a polygonal structure, etc., that is, a shape structure that can ensure interlocking.

[0033] As a technical optimization solution of the present utility model, the thickness of the conical semi-cylinder 2 is less than the thickness of the T-shaped mortise and tenon structure 3, that is, the T-shaped mortise and tenon structure 3 is thicker. Moreover, the T-shaped mortise and tenon structure 3 adopts a thickness gradient design from thick to thin. This design also has the effect of a reinforcing rib and can play two roles: The first is to strengthen the strength when several T-shaped mortise and tenon structures 3 are interlocked; the second is that compared with an increase in the overall thickness, it effectively reduces the overall weight of the device, facilitating high-altitude operation, and thus also saving more materials and costs.

[0034] As a technical optimization solution of the present utility model, the inner sleeve mechanism includes several inner wedge combination units 4. Each inner wedge combination unit 4 is respectively provided with corresponding convex structures 12 and concave structures 13 on the left and right. Several inner wedge combination units 4 can be assembled and spliced with each other through the corresponding convex structures 12 and concave structures 13, and are spliced to form a hollow cone with a set gap.

[0035] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, several inner wedge combination units 4 can be pre-set in terms of quantity and specifications during production according to the internal sizes of the two conical semi-cylinders 2, so that the enclosed hollow cone can be set inside the corresponding two conical semi-cylinders 2.

[0036] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the mating shapes of the top of the convex structure 12 and the bottom of the concave structure 13 can be any polygon such as a triangle, a semi-circle, an ellipse, a peach shape, a heart shape, etc.

[0037] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the convex structure 12 and the concave structure 13 can be respectively set with one convex and one concave on the left, or two convexes and two concaves can be respectively set on the left and right.

[0038] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the number of the convex structures 12 and the groove structures 13 can be one, two, three, etc., n numbers.

[0039] As a technical optimization solution of the present utility model, a hollow cone formed by splicing a plurality of inner wedge combination units 4 can be coaxially inserted into a conical cylinder formed by combining two conical semi-cylinders 2. The outer side of the hollow cone fits the inner sides of the two conical semi-cylinders 2, and the inside of the hollow cone is used for passing a wire. A spiral convex structure 5 is arranged on the inner side surface of the hollow cone, that is, the plurality of inner wedge combination units 4 are correspondingly provided with spiral convex structures 5. Since the wire is formed by stranding a plurality of metal wires, the spiral convex structures 5 of the plurality of inner wedge combination units 4 can better cooperate with the outer surface shape of the wire to form a larger contact surface under the action of tension, thereby generating a greater holding force.

[0040] As a technical optimization solution of the present utility model, a plurality of reserved grooves 6 are arranged on one side of the inner wedge combination unit 4 that fits the conical semi-cylinder 2. The reserved grooves 6 are arranged perpendicular to the wire. Two or more inner wedge combination units 4 can be assembled by a spring hook 7, and both ends of the spring hook 7 can be inserted and matched with the corresponding two reserved grooves 6. The setting of the spring hook 7 facilitates the installation of the plurality of inner wedge combination units 4 during high-altitude operations.

[0041] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, 4 reserved grooves 6 can be arranged on the side of the inner wedge combination unit 4 in the up, down, left, and right directions, or more, and the number of the arranged reserved grooves is an even number.

[0042] As a technical optimization solution of the present utility model, pulling plates 8 are rotatably installed on the sides of the two conical semi-cylinders 2, and a plurality of mounting holes 11 are arranged at one ends of the two pulling plates 8 away from the conical semi-cylinders 2.

[0043] As a technical optimization solution of the present utility model, a clip 9 is installed between one ends of the two pulling plates 8 away from the conical semi-cylinders 2. The clip 9 is in the shape of a triangular plate, and two circular tightener hanging holes 10 are arranged on the triangular plate. When tightening the wire, one end of the tightener is hooked into the tightener hanging hole 10. Compared with the traditional method of arranging the hanging hole on the clamp body, the setting of the clip 9 greatly reduces the force borne by the main body during the wire tightening process, thereby avoiding the deformation of the main body caused by excessive force.

[0044] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the tightener hanging hole 10 is not limited to a circular shape, and can also be any polygon such as a trapezoid, a square, a rectangle, a pentagon, etc.

[0045] On the premise of the same strength and technical standards, the device reduces material costs due to structural optimization. Due to the adjustment of the positions of each functional part, casting and forging processes with one-time molding can be adopted, thus improving production efficiency and reducing energy consumption compared with traditional casting processes. The material used and the overall weight of the wire clamp are reduced, making the wire clamp more portable and faster to install during high-altitude operations. Due to higher strength, the wire clamp has better strength after installation, longer service life, and higher durability.

[0046] The working principle is as follows:

[0047] A number of inner wedge combination units 4 are assembled and spliced with each other through corresponding convex structures 12 and concave structures 13 to form a hollow cone with a set gap. Two or more inner wedge combination units 4 can be assembled through spring hooks 7. The setting of the spring hooks 7 facilitates the installation of a number of inner wedge combination units 4 during high-altitude operations. At the same time, two conical semi-cylinders 2 are merged left and right through a number of T-shaped mortise and tenon structures 3, and the two conical semi-cylinders 2 can be merged to form a conical cylinder. Then, the wire to be fixed is inserted into the hollow cone. By tightening the wire, a number of inner wedge combination units 4 squeeze the two conical semi-cylinders 2, and the effect of extrusion fixation can be achieved.

[0048] Compared with the existing wire clamp device, the two conical semi-cylinders 2 can be spliced left and right, meeting the effect of convenient installation and effectively improving work efficiency.

[0049] When a number of inner wedge combination units 4 are set for wire insertion, a number of inner wedge combination units 4 are arranged around the wire and fixed in sequence, so that the wire can be inserted conveniently, facilitating the subsequent wire tightening operation.

[0050] At the same time, the wire is formed by stranding multiple metal wires. The spiral convex structures 5 of a number of inner wedge combination units 4 can better match the external surface shape of the wire to form a larger contact surface under the action of tension, thereby generating a greater grip force. Moreover, it can provide a closed-loop grip force. While meeting the grip force standard, it is not easy to damage the insulating skin wrapped outside the wire.

[0051] When tightening the wire, one end of the wire tightener is hooked in the wire tightener hanging hole 10. Compared with the traditional setting of the hanging hole on the wire clamp body, the setting of the clamping piece 9 greatly reduces the force borne by the main body during the wire tightening process, thereby avoiding deformation of the main body caused by excessive force and effectively improving the service life of the device.

[0052] Embodiment 2

[0053] Refer to Figure 7 , the difference between this embodiment and Embodiment 1 is:

[0054] The clamp body 1 further includes two polygonal conical cylinders 14. The two polygonal conical cylinders 14 are also respectively provided with a T-shaped mortise and tenon structure 3 that can be engaged with each other. When the two polygonal conical cylinders 14 are combined, the corresponding inner sleeve mechanism of the corresponding specification can also be placed inside the clamp body 1. The working principle of the two polygonal conical cylinders 14 is the same as that of the two conical semi-cylinders 2, and will not be elaborated here.

[0055] For the above example, those skilled in the art should know that when implementing the above technical solution, the size specifications of the polygonal conical cylinder 14 are not limited to a single specification form. The polygonal conical cylinder 14 can be preset with multiple size specifications according to the use requirements, and the corresponding inner sleeve mechanism can also be set with corresponding size specifications.

[0056] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to using the combination of two polygonal conical cylinders 14. It can also be composed of 4 quarter-conical parts, or can be composed of a larger number of 2n conical parts.

[0057] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
