Description

Technical Field

[0001] The invention relates to the technical field of wire connectors, and in particular to a locking tool for a wire connector. Background Art

[0002] Wire connectors are commonly used tools in electrician wiring and are also very common in home decoration. They are suitable for single-strand hard wires or multi-strand hard wires with a certain cross-sectional area of ​​the wire. This connector has rated voltage and rated current limitations, such as a rated voltage of 40 volts and a rated current of 24 amperes. According to the number of connected wires, it can be divided into two-wire connectors, three-wire connectors, five-wire connectors and other types. Wire connectors simplify the connection between single-strand hard wires and multi-strand soft wires, becoming an ideal connector between the two. They are often used in the connection of wires for chandeliers, ceiling lamps, downlights, spotlights, exhaust fans, ventilation fans, etc.

[0003] The locking tool of the wire connector mainly uses mechanical pressure to press the wire connector and the wire tightly together. Specifically, the locking tool usually includes a pressure rod and a fixed block. The fixed block is provided with a cavity for fixing the wire connector, and the shape of the cavity corresponds to the shape of the wire connector to be locked. The pressure rod is provided with a handle, an external thread and a pressure head. The handle is used to receive the rotational force to realize the rotation of the pressure rod, the pressure head is used to squeeze the wire pressing block of the wire connector, and the external thread is used to cooperate with the internal thread on the fixed block to realize the tightening and loosening of the pressure rod.

[0004] When connecting cables, traditional cable adapters and cable splicing devices require external force to make the wire connector reach a self-locking state. Either the cable adapter compresses the cable through screws and threads; or it requires the use of wire crimping pliers or knocking tools to ensure that it reaches a self-locking state, and then a locking clamp is set to lock it. These methods have technical problems such as unchanged operation and unstable locking state maintenance time. Summary of the invention

[0005] In order to solve the above technical problems, an object of the present invention is to provide a locking tool for a wire connector, which is easy to operate and can significantly increase the maintenance time of the locking state.

[0006] To achieve the above object, the present invention provides the following technical solutions: A locking tool for a wire connector, comprising a ring sleeve, a threaded hole is formed on the ring sleeve, a threaded rod is connected to the threaded hole through the inner thread, a pressing block is arranged at one end of the threaded rod facing the ring sleeve, an operating block is arranged at the top of the threaded rod, an operating rod is hingedly connected to the edge of the operating block through a pin shaft, and a hook plate is arranged at the other end of the operating rod through a controllable telescopic component; A fixing ring corresponding to the threaded hole is fixedly arranged on the ring sleeve, a locking spring is arranged on one side of the fixing ring away from the ring sleeve, a movable ring is fixedly arranged on the other end of the locking spring, and the threaded rod passes through the movable ring, the locking spring, the fixing ring and the threaded hole in sequence; A rotating ring is rotatably sleeved outside the fixed ring via an annular bearing, and a hook groove matched with the hook plate is opened on the side of the rotating ring.

[0007] By adopting the above scheme, in the initial state of the locking and pressing tool, the locking and pressing tool includes a ring sleeve, a threaded rod, a pressure block, an operating block, an operating rod, a controllable telescopic component, a hook plate, a fixed ring, a locking spring, a movable ring and a rotating ring and other components; before the operation is performed, the threaded rod passes through the movable ring, the locking spring and the fixed ring, and is inserted into the threaded hole, but is not completely locked; the operating rod is hinged to the operating block through a pin shaft, and the hook plate is connected to the other end of the operating rod through the controllable telescopic component, and at this time the hook plate is not connected to the hook groove on the side of the rotating ring; in the locking During the tightening process, the user holds the operating rod and turns the operating block effortlessly through the lever principle; as the operating block turns, the threaded rod gradually rotates in the threaded hole and moves forward, pushing the pressing block to lock the wire connector; during the movement of the threaded rod, the user adjusts the length of the controllable telescopic component to make the hook plate and the hook groove on the side of the rotating ring gradually approach and finally connect; once the hook plate and the hook groove are fully connected, a stable locking structure is formed; the locking spring always applies pressure to the movable ring, which in turn exerts a certain pressure on the threaded rod through the movable ring Friction; this friction helps prevent the threaded rod from loosening due to vibration or other external forces in the locked state; then, regarding the maintenance of the locked state: when the hook plate is connected to the hook groove, due to the elastic force of the locking spring and the close fit between the hook plate and the hook groove, the threaded rod is firmly locked in the threaded hole, thereby ensuring the locked state of the wire connector; even under the action of vibration or external force, due to the elastic force of the locking spring and the stable connection between the hook plate and the hook groove, the threaded rod is not easy to loosen or rotate, thereby greatly extending the maintenance time of the locked state; when unlocking is required, the user first separates the hook plate from the hook groove through the controllable telescopic component; then, the operating rod is rotated in the opposite direction to make the threaded rod gradually rotate and move backward in the threaded hole, thereby releasing the locking pressure on the wire connector; in summary, the locking tool of the wire connector realizes the locking and unlocking functions of the wire connector through the steps of rotating the operating rod, moving the threaded rod, connecting the hook plate and the hook groove, and the action of the locking spring; its working principle is simple and clear, easy to operate, and can greatly improve the maintenance time of the locked state.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] The first embodiment, such as Figures 1 to 2 As shown, a locking tool for a wire connector comprises a ring sleeve 1, a threaded hole is provided on the ring sleeve 1, a threaded rod 2 is connected through the inner thread of the threaded hole, a pressing block 3 is provided on the end of the threaded rod 2 facing the ring sleeve 1, an operating block 4 is provided on the top of the threaded rod 2, an operating rod 501 is hinged on the edge of the operating block 4 through a pin, and a hook plate 502 is provided on the other end of the operating rod 501 through a controllable telescopic component; a fixed ring 601 corresponding to the threaded hole is fixedly provided on the ring sleeve 1, a locking spring 602 is provided on the side of the fixed ring 601 away from the ring sleeve 1, and a movable ring 603 is fixedly provided on the other end of the locking spring 602, and the threaded rod 2 passes through the movable ring 603, the locking spring 602, the fixed ring 601 and the threaded hole in sequence; a rotating ring 604 is provided on the outside of the fixed ring 601 through an annular bearing rotating sleeve, and a hook groove 605 adapted to the hook plate 502 is provided on the side of the rotating ring 604.

[0026] like Figures 1 to 2As shown, the edge of the operating block 4 is hinged with an operating rod 501 through a pin shaft. This design allows the user to use the lever principle to rotate the operating block 4 with a small force, thereby driving the threaded rod 2 to rotate; the application of the lever principle greatly reduces the user's operating burden, making the use of the locking tool more convenient; the other end of the operating rod 501 is provided with a hook plate 502 through a controllable telescopic component; this design allows the user to adjust the length of the hook plate 502 as needed, so that the hook plate 502 can be more easily connected to the hook groove 605, or retracted when not needed, avoiding interference during operation and improving the flexibility and convenience of operation; the hook plate 502 is adapted to the hook groove 605 on the side of the rotating ring 604, and this design can form a stable connection in the locked state to prevent the threaded rod 2 from loosening due to vibration or other external forces; the close fit between the hook plate 502 and the hook groove 605 ensures the stability and durability of the locked state; a locking spring 602 is provided on the side of the fixing ring 601 away from the ring sleeve 1, and the other end of the locking spring 602 is fixed A movable ring 603 is provided; the elastic force of the locking spring 602 can further increase the friction between the threaded rod 2 and the threaded hole, preventing the threaded rod 2 from rotating or loosening in the locked state; this design not only improves the stability of the locked state, but also prolongs the locking time; the threaded connection between the threaded rod 2 and the threaded hole is itself a reliable connection method, which can withstand large tension and pressure; under the joint action of the locking spring 602 and the connection between the hook plate 502 and the hook groove 605, the reliability of this threaded connection is further improved, thereby ensuring the long-term maintenance of the locked state; in summary, the locking tool of the wire connector achieves the beneficial effects of convenient operation and greatly improving the locking state maintenance time by applying the lever principle, controllable telescopic components, the connection between the hook plate 502 and the hook groove 605, the locking spring 602 and the threaded connection; these designs not only improve the convenience of using the locking tool, but also ensure the stability and durability of the locking state, providing a strong guarantee for the installation and maintenance of the wire connector.

[0027] like Figure 1As shown, the operating rod 501 includes a fixedly connected triangular plate-shaped connecting plate and a cylindrical extension rod, the connecting plate is hinged with a pin, and the extension rod is connected to a controllable telescopic assembly; when the user needs to rotate the operating block 4, he can hold the connecting plate and apply a rotational force. Since the connecting plate and the operating block 4 are hinged with a pin, the rotation of the connecting plate will drive the operating block 4 to rotate, and then the locking or unlocking of the wire connector is realized through the threaded rod 2. The connection between the extension rod and the controllable telescopic assembly allows the user to adjust the position of the hook plate 502 as needed. By rotating the threaded sleeve in the controllable telescopic assembly (such as the internal threaded sleeve 902 and the external thread design mentioned above), the position of the extension rod relative to the first movable tube 901 can be changed, thereby adjusting the relative position of the hook plate 502 and the hook groove 605 on the rotating ring 604, which is convenient for connection or separation. The triangular plate-shaped connecting plate design utilizes the principle of leverage, so that the user can realize the rotation of the operating block 4 with less force. The shape and size of the connecting plate can be adjusted according to actual needs to optimize the lever effect. The threaded connection in the controllable telescopic assembly provides a stable connection and adjustment method. As the sleeve rotates, the tight fit between the outer and inner threads creates enough friction to keep the extension rod in place, while also allowing for easy position adjustment when needed.

[0028] like Figure 1As shown, the controllable telescopic assembly includes a first movable tube 901, the outer wall of the first movable tube 901 is rotatably connected to an internal thread sleeve 902 through a bearing, and a first fixed tube 903 is fixedly arranged at one end of the extension rod facing the hook plate 502, and the outer wall of the first fixed tube 903 is provided with an external thread, which is adapted to the internal thread of the internal thread sleeve 902, and the first movable tube 901 is used to accommodate the first fixed tube 903; the external thread of the first fixed tube 903 is adapted to the internal thread of the internal thread sleeve 902, which means that when the internal thread sleeve 902 rotates, it moves along the external thread of the first fixed tube 903, thereby changing the position of the first fixed tube 903 relative to the first movable tube 901. This threaded connection provides a stable connection and adjustment method, allowing the user to adjust the position of the first fixed tube 903 (and the hook plate 502 connected thereto) by rotating the internal thread sleeve 902 when necessary. When the user needs to adjust the position of the hook plate 502, it can be achieved by rotating the internal thread sleeve 902. Since the internal threaded sleeve 902 is rotatably connected to the first movable tube 901 through a bearing, rotating the internal threaded sleeve 902 will not cause the first movable tube 901 to rotate together. As the internal threaded sleeve 902 rotates, it moves along the external thread of the first fixed tube 903, thereby pushing or pulling the first fixed tube 903 (as well as the extension rod and the hook plate 502) to extend and retract relative to the first movable tube 901. In this way, the user can accurately adjust the position of the hook plate 502 so that it is aligned with and connected to the hook groove 605 on the rotating ring 604. The design of the controllable telescopic component allows the position of the hook plate 502 to be flexibly adjusted as needed, which increases the adaptability and flexibility of the locking tool. By simply rotating the internal threaded sleeve 902, the user can quickly adjust the position of the hook plate 502, thereby simplifying the operation process and improving work efficiency.

[0029] like Figure 1 As shown, the outer wall of the threaded sleeve is evenly distributed with a number of anti-skid concave edges in an annular shape; the main function of the anti-skid concave edges is to increase the friction between the user's hand and the threaded sleeve to prevent the hand from slipping or difficulty in applying sufficient force when rotating the threaded sleeve. When the user needs to rotate the threaded sleeve to adjust the length of the controllable telescopic component, the fingers can more easily grasp and stably rotate the threaded sleeve without losing control due to hand slippage. By adding anti-skid concave edges, the user can adjust the length of the controllable telescopic component more safely and accurately, thereby ensuring that the hook plate 502 can be correctly aligned with the hook groove 605 on the rotating ring 604 and connected. This improves the convenience and accuracy of the operation of the locking tool and reduces failures or damage caused by operating errors.

[0030] like Figure 3As shown, the movable ring 603 is connected to the fixed ring 601 through a sliding telescopic tube 7, the threaded rod 2 is inside the sliding telescopic tube 7, and the locking spring 602 is outside the sliding telescopic tube 7; the sliding telescopic tube 7 includes a second fixed tube 701 fixedly connected to the fixed ring 601, and a second movable tube 702 is slidably connected inside the second fixed tube 701, and the other end of the second movable tube 702 is fixedly connected to the movable ring 603; the sliding connection of the second movable tube 702 in the second fixed tube 701 allows the movable ring 603 to move to a certain extent relative to the fixed ring 601. This movement is carried out along the axis direction of the threaded rod 2. The threaded rod 2 passes through the sliding telescopic tube 7 and is supported by the channel inside it. This ensures that the threaded rod 2 can remain stable when rotating and moving, and will not bend or deviate from the axis due to external force. The locking spring 602 surrounds the outside of the sliding telescopic tube 7, one end of which is connected to the fixed ring 601, and the other end is connected to the movable ring 603 (or indirectly connected through the second movable tube 702). The elastic force of the locking spring 602 acts on the movable ring 603, providing a thrust in the direction of the fixed ring 601. This thrust helps to maintain a close fit between the threaded rod 2 and the threaded hole, and increases the stability of the locking. When the position of the threaded rod 2 needs to be adjusted, the user can move the hook plate 502 by operating the operating rod 501 and the controllable telescopic component, and then drive the movement of the movable ring 603 through the interaction between the rotating ring 604 and the hook groove 605. The movement of the movable ring 603 will compress or release the locking spring 602, thereby allowing the threaded rod 2 to be adjusted accordingly in the threaded hole. Once adjusted to the desired position, the elastic force of the locking spring 602 will help maintain the locking state of the threaded rod 2.

[0031] like Figure 1As shown, the bottom of the pressing block 3 is rotatably connected to an arc-shaped pressing plate 801 that is in direct contact with the wire through a bearing, and an anti-skid pad 802 is bonded to the side of the arc-shaped pressing plate 801 facing the wire; the inner wall of the ring sleeve 1 is set to a frosted texture in the vertical projection coverage area of ​​the arc-shaped pressing plate 801 and is provided with a plurality of arc-shaped anti-skid ridges 803; the arc-shaped pressing plate 801 is rotatably connected to the bearing, and can rotate freely relative to the pressing block 3. This rotation design allows the arc-shaped pressing plate 801 to better adapt to the shape and size of the wire, ensuring that the wire can be pressed evenly and tightly during the locking process. The anti-skid pad 802 is usually made of a material with a high friction coefficient, such as rubber or silicone. It is attached to the side of the arc-shaped pressing plate 801 facing the wire, which can significantly increase the friction between the arc-shaped pressing plate 801 and the wire. This helps prevent the wire from sliding due to uneven force or external interference during the locking process, thereby ensuring the firmness of the locking pressure. The frosted texture of the inner wall of the ring sleeve 1 and the anti-skid ridge 803 are designed to increase the friction between the ring sleeve 1 and the wire connector. This design not only helps prevent the wire connector from sliding or rotating during the locking process, but also improves the stability of the locking pressure. The arc-shaped design of the anti-skid ridge 803 enables it to better match the contour of the wire connector, further increasing the firmness of the locking pressure.

[0032] like Figures 1 to 3 As shown, the number of operating rods 501 is three, and the three operating rods 501 are evenly distributed in a ring on the operating block 4. The number of hook grooves 605 is three or a multiple of three, and multiple hook grooves 605 are evenly distributed in a ring on the side of the rotating ring 604; the side of the rotating ring 604 is provided with hook grooves 605, and the number of hook grooves 605 is three or a multiple of three, and they are also evenly distributed in a ring. This layout matches the number of operating rods 501, ensuring that each operating rod 501 can correspond to one or more hook grooves 605, so that the user can accurately control the rotation angle of the rotating ring 604 through the operating rod 501. The hook plate 502 is a key component connecting the controllable telescopic component and the rotating ring 604, and it can be clamped with the hook groove 605 under the push of the controllable telescopic component.

[0033] like Figure 3As shown, the cross section of the clamping part of the hook plate 502 and the hook groove 605 is rectangular. This design provides a stable clamping structure, because the rectangular cross section can prevent the hook plate 502 from rotating or sliding during the clamping process, thereby ensuring the firmness of the locking. The user can drive the rotation of the rotating ring 604 by rotating any operating rod 501. Since the number of operating rods 501 and hook grooves 605 is three or multiples of three, and they are evenly distributed in a ring, the user can easily select any operating rod 501 for operation without worrying about uneven force distribution or inaccurate rotation angle. When it is necessary to lock the wire connector, the user can push the hook plate 502 to the corresponding hook groove 605 through the controllable telescopic component for clamping. Since the clamping part of the hook plate 502 and the hook groove 605 is a rectangular cross section, the clamping process is stable and firm, ensuring that the wire connector can be effectively locked. This design also improves the convenience of operation of the locking tool, because the user can complete the locking process through a simple rotation operation without complicated operation steps or tool assistance.

[0034] like Figure 3 As shown, the cross section of the connection between the hook plate 502 and the hook groove 605 is rectangular; the rectangular cross section design provides a stable connection structure. When the hook plate 502 is connected to the hook groove 605, the rectangular shape can prevent the hook plate 502 from rotating or sliding sideways during the connection process, thereby ensuring the firmness and stability of the locking and pressing. The rectangular cross section makes the fit between the hook plate 502 and the hook groove 605 more precise. Due to the consistency of the shape, the hook plate 502 can be accurately inserted into the hook groove 605 to form a tight connection, reducing the risk of locking and pressing failure due to improper fit. The rectangular cross section design also enhances the connection strength between the hook plate 502 and the hook groove 605. When subjected to external forces, the rectangular structure can better resist deformation and damage, thereby extending the service life of the locking and pressing tool.

[0035] like Figure 1As shown, the ring sleeve 1, the threaded rod 2, the operating block 4, the operating rod 501, the fixed ring 601, the rotating ring 604, the controllable telescopic component and the hook plate 502 are all made of stainless steel; the stainless steel material has excellent corrosion resistance and can resist the erosion of various corrosive media (such as water, acid, alkali, etc.). This allows the locking tool to maintain good performance and appearance even in a humid and highly corrosive environment. The stainless steel material has high strength and hardness and can withstand large pressure and tension. This ensures that the locking tool can provide sufficient clamping force when locking the wire connector to prevent the wire from loosening or falling off. The stainless steel material also has good wear resistance and can resist wear and scratches. This allows the locking tool to maintain a smooth and neat appearance during use, while reducing the performance degradation caused by wear. The stainless steel material is easy to clean and maintain. Even if dust or dirt accumulates during use, its original gloss and performance can be restored by simply wiping or washing.

[0036] The second embodiment, such as Figure 4 As shown, one operating rod 501 corresponds to at least two controllable telescopic components; this design allows the user to adjust the length of multiple controllable telescopic components at the same time through a single operating rod 501, thereby achieving synchronous adjustment of the position of the hook plate 502. When the positions of multiple hook plates 502 need to be adjusted at the same time, the user only needs to operate one operating rod 501, which greatly simplifies the operation process and improves work efficiency. By combining multiple controllable telescopic components with a single operating rod 501, the user can more easily control the positions of multiple hook plates 502, thereby completing the locking or unlocking operation more quickly. This design also increases the flexibility and adaptability of the locking tool, enabling it to adapt to wire connectors of different sizes or shapes.
