Description

Technical Field

[0001] The invention relates to the technical field of special clothing, in particular to a clamping device used for welding connectors of live working shielding clothing. Background Art

[0002] In live-line operations in the power industry, workers need to wear special shielding suits (also called equipotential equalizing suits) to ensure personal safety. This type of shielding suit forms a complete conductive system through precise connection design, such as the close connection between clothes and gloves, pants and socks and shoes. When workers wear a complete set of shielding suits, their bodies reach the same potential state as the high-voltage equipment environment, thereby effectively shielding the dangerous current that easily flows through the human body, ensuring the safety of workers in high-voltage environments.

[0003] However, in the production and maintenance process of shielding suits, the welding of connectors is a crucial link. Traditional connection methods often rely on the design of a movable sleeve in conjunction with a single spring. However, this design has significant limitations: the rebound force of a single spring is limited, and it is difficult to stably maintain the tight fit of the movable sleeve during the welding process, which can easily cause the sleeve to loosen and affect the welding quality. In addition, the existing welding process often lacks a special clamping mechanism to stabilize the movable sleeve so that it remains stationary during the welding process. This not only affects the accuracy and reliability of welding, but also easily causes the connector to be welded loosely due to slight movements during the welding process, thereby affecting the overall protective effect of the shielding suit. Summary of the invention

DETAILED DESCRIPTION

[0023] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings are prone to use exaggerated methods to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0024] See also Figure 1-5 , an embodiment provided by the present invention:

[0025] A clamp for welding connectors of live working shielding clothing comprises a fixed sleeve 1, a movable sleeve 2, a bullet-locking sleeve 5 and a first spring 112, wherein the first spring 112 is movably mounted on the inner wall of the fixed sleeve 1, and the outer surface of the fixed sleeve 1 is provided with two groups of circular grooves 111, one end of the movable sleeve 2 is connected to a limiting plate 3, and one end of the limiting plate 3 is connected to a clamping sleeve 114, one side outer surface of the limiting plate 3 is connected to a second spring 113, two groups of clamping teeth 115 are fixedly mounted on the outer surface of the clamping sleeve 114, a first wire connection hole 4 is formed on the outer surface of the movable sleeve 2, a second wire connection hole 6 is formed on the outer surface of the bullet-locking sleeve 5, and a clamping mechanism is provided at one end of the fixed sleeve 1, the clamping mechanism comprises a clamping ring 9, and the clamping ring 9 is fixedly mounted on the outer surface of one side of the fixed sleeve 1, a thread is formed on the outer surface of the clamping ring 9, and an extrusion ring 7 is movably mounted on the outer surface of the clamping ring 9.

[0026] Furthermore, the outer surface of the clamping ring 9 is provided with a plurality of vertical through grooves 911, which allow the clamping ring 9 to deform, especially radially contract, when being squeezed. This design enables the clamping ring 9 to fit more closely and clamp the bullet lock sleeve 5, thereby improving the stability and reliability of the clamping.

[0027] Furthermore, a plurality of operating rods 8 are fixedly mounted on the outer surface of the extrusion ring 7, and the operating rods 8 provide convenient force application points for the operator, making it easier to control the rotation and movement of the clamping ring 7. By rotating or pushing the operating rods 8, the operator can easily adjust the position and clamping force of the clamping ring 7, thereby achieving fast and accurate clamping operation.

[0028] Furthermore, one side of the plurality of operating rods 8 is in an arc shape, and the arc shape design makes the operating rod 8 more ergonomic and convenient for operators to hold and operate. At the same time, the arc shape also reduces friction and resistance during operation, improving the smoothness and comfort of operation.

[0029] Furthermore, the outer surfaces of the multiple groups of operating rods 8 are wrapped with rubber, and the rubber layer can increase the friction between the operator's hand and the operating rod 8 to prevent operating errors caused by hand slippage. At the same time, the rubber layer can also absorb some impact and vibration to reduce the discomfort of the operator's hand.

[0030] Furthermore, one end of the extrusion ring 7 is conical, and the conical design facilitates the extrusion ring 7 to penetrate the clamping ring 9 and start the clamping process. As the extrusion ring 7 rotates and moves, its conical end can gradually push the clamping ring 9 inward to achieve a stable clamping effect.

[0031] Furthermore, a spring limiting ring 811 is provided on the inner wall of the fixed sleeve 1. The spring limiting ring 811 provides stable support and positioning for the first spring 112, thereby preventing the first spring 112 from shifting or falling off during operation.

[0032] Working principle: First, the second wire connection hole 6 and the first wire connection hole 4 are designed on the movable sleeve 2 and the bullet lock sleeve 5 respectively, for the subsequent connection of the metal wire, and the first spring 112 is placed inside the fixed sleeve 1, and the spring limit ring 811 on the inner wall of the fixed sleeve 1 provides support to ensure that the first spring 112 can function stably. Then, the bullet lock sleeve 5 is inserted into the inner wall of the fixed sleeve 1 and passed through one end of the fixed sleeve 1 to prepare for the subsequent connection and clamping.

[0033] Next, the engaging sleeve 114 is connected to the fixed sleeve 1, at which time the latching teeth 115 enter the circular groove 111 on the outer surface of the fixed sleeve 1, and the movable sleeve 2 is rotated to slide the latching teeth 115 along the circular groove 111 until the latching teeth 115 abut against the lowest point of the circular groove 111. In this process, the second spring 113 on one side of the limiting plate 3 abuts against the first spring 112 inside the fixed sleeve 1, thereby increasing the overall rebound force and stability.

[0034] Then, through the action of the clamping mechanism, the clamping mechanism includes a clamping ring 9 and an extrusion ring 7. The clamping ring 9 is fixedly mounted on the outer surface of one side of the fixed sleeve 1, and a plurality of vertical through grooves 911 are provided on the clamping ring 9 so that the clamping ring 9 can be deformed when being extruded. One end of the extrusion ring 7 is designed to be conical, so that it can be inserted into the clamping ring 9 and the extrusion ring 7 can be moved along the outer surface of the clamping ring 9 by rotating the operating rod 8.

[0035] When the extrusion ring 7 rotates and moves along the clamping ring 9, the conical end thereof generates an inward extrusion force on the clamping ring 9, so that the clamping ring 9 contracts and tightly clamps the outer surface of the bullet lock sleeve 5. In this way, the bullet lock sleeve 5 and the movable sleeve 2 are stably fixed together, providing reliable support for subsequent wire welding.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
