Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a threading joint which is easy to turn. Background Art

[0002] During the installation or wiring process of lighting fixtures, the powered cables are usually passed through the inside of the lamp bracket to prevent the cables from being exposed to the outside space. Sometimes the cables need to be bent at different angles, and sometimes the direction of the cables needs to be changed to facilitate the cables to reach different outlets, and these angles and directions may need to be adjusted at any time.

[0003] The existing wiring method generally allows the cable to pass directly through the hollow part of the bracket. There is no special protective shell for the cable at the corners and twists of the bracket, which makes the cable easily squeezed or bent by the structure of the bracket corners. It is also not easy to adapt to different bending angles. Long-term use may cause excessive squeezing or pulling on the cable. In severe cases, it may even damage the cable surface, causing risks such as exposed wires, cable breakage, or cable connection failure, affecting user safety.

[0004] In view of the above shortcomings, we need to develop a threading connector that is easy to turn to meet the needs of the majority of users. Utility Model Content

[0005] In view of the above-mentioned existing threading methods that make the cables easily squeezed or bent, inconvenient to adapt to different bending angles, and damage the cable surface, the technical solution adopted by the utility model to solve the technical problems is:

[0006] A threading joint that is easy to turn, comprising a threading base, a rotation limiter, a rotating member and a mounting shell, wherein the mounting shell is provided with a mounting limiter opening for the rotating member to pass through, and the threading base, the rotation limiter and the rotating member are all provided with a main threading hole that is connected;

[0007] A spherical structure portion is provided at one end of the rotating member and is located between the rotating limit member and the mounting shell. The spherical structure portion is located between the rotating limit member and the mounting shell and extends a limit column. The rotating limit member is provided with an arc-shaped inner cavity for accommodating the spherical structure portion, and the arc-shaped inner cavity is provided with a limit groove for limiting the movable space of the limit column.

[0008] Furthermore, in some embodiments, a rotation gasket is further included, wherein the rotation gasket is installed between the rotation limiter and the installation shell, and the rotation gasket is provided with an arc-shaped contact surface that contacts the surface of the spherical structure.

[0009] Furthermore, in some embodiments, the other end of the rotating member is provided with a connecting portion for connecting to the outside, and the connecting portion is provided with a limiting platform for limiting the rotation direction of the rotating member.

[0010] Further, in some embodiments, an end of the wire passing base away from the rotation limiter is provided with a base mounting portion for connecting to the outside, and the main wire passing hole includes a side wire passing hole located at the base mounting portion.

[0011] Further, in some embodiments, the wire passing base is provided with a base positioning portion, the mounting shell is provided with a shell positioning portion, and the shell positioning portion is provided with a positioning blind hole for the base positioning portion to extend into.

[0012] Furthermore, in some embodiments, a fastener for installation is also included, and the fastener passes through the wire-passing base and the rotation limiter and is detachably connected to the installation shell.

[0013] Further, in some embodiments, the wire-passing base is provided with a first mounting portion for the fastener to pass through, and the rotation limiting member is provided with a second mounting portion corresponding to the first mounting portion.

[0014] Further, in some embodiments, the mounting shell is provided with a third mounting portion for connecting the fastener, and the second mounting portion is provided with a mounting limiting cavity for the third mounting portion to extend into.

[0015] Further, in some embodiments, a plurality of the first mounting portions are arranged at intervals around the circumference of the main cable hole.

[0016] Furthermore, in some embodiments, a reinforcing rib for reinforcing the second mounting portion is provided on the outer side of the rotation limiting member.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1. The utility model is a connector structure for protecting cables and can be twisted in a large direction to meet installation requirements. A spherical structure of a wire-passing base and an installation shell clamping a rotating member is used as a rotation method that is convenient for turning. A rotation limiter that limits the turning range is provided inside the wire-passing base, and a plurality of wire-passing holes that are convenient for passing cables are provided on the wire-threading connector, so that the cables can pass through stably without being squeezed or bent, and the externally connected structure can be freely turned and twisted in a large range. In addition to meeting the rotation requirements, it can also protect the cables, facilitate user use, and improve safety of use.

[0019] 2. The utility model adds a rotating gasket between the rotating limiter and the mounting shell to facilitate stable rotation. The rotating gasket can be made of silicone material, so that the arc-shaped contact surface of the rotating gasket can elastically contact the surface of the spherical structure to avoid vibration due to incomplete contact when the rotating part rotates. The silicone material has good wear resistance, which avoids the spherical structure from directly contacting the arc-shaped inner cavity. The rotating gasket can be detachably installed between the rotating limiter and the mounting shell. When the rotating gasket is severely worn, it can be removed and replaced without affecting the replacement of the overall structure, reducing maintenance costs and improving convenience of use.

[0020] 3. The wire passing base, rotating limiter and installation shell of the utility model are provided with multiple installation parts and positioning parts. After installation, the spherical structure of the rotating part is fully and stably clamped, so that the rotation of the rotating part is more stable and smooth, and the rotating part is prevented from being easily loosened and displaced. The multi-layer shell from the outside to the inside protects the cables passing through the wire passing holes, so that the cables are not easily damaged or squeezed. The rotation radius of the threading connector is large, which has little effect on the bending degree of the cables passing through, thereby ensuring the stable use of the cables and reducing safety hazards and usage hazards.

[0030] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 8 As shown, a threading joint that is easy to turn, includes a threading base 1, a rotation limiter 2, a rotating member 3 and a mounting shell 4, wherein the mounting shell 4 is provided with a mounting limiter opening 41 for the rotating member 3 to pass through, and the threading base 1, the rotation limiter 2 and the rotating member 3 are all provided with a main threading hole 5 that is connected;

[0032] A spherical structure portion 31 is provided at one end of the rotating member 3 and is located between the rotating limit member 2 and the mounting shell 4. The spherical structure portion 31 is located between the rotating limit member 2 and the mounting shell 4 and extends a limit column 32. The rotating limit member 2 is provided with an arc-shaped inner cavity 21 for accommodating the spherical structure portion 31. The arc-shaped inner cavity 21 is provided with a limit groove 22 for limiting the movable space of the limit column 32.

[0033] Specifically, in some embodiments, the wire-passing base 1 is used as a connector base for the cable to pass through and connect to an external structure. The wire-passing base 1 is provided with a base inner cavity for accommodating and installing a rotation limiter 2. The rotation limiter 2 and the mounting shell 4 are components for cooperating to clamp the rotating member 3. The mounting shell 4 is provided with a shell inner cavity for accommodating and installing the rotation limiter 2 and the rotating member 3. The rotation limiter 2 is limitedly connected to the side of the wire-passing base 1 facing the rotating member 3. The rotating member 3 is a rotatable component hinged between the rotation limiter 2 and the mounting shell 4. The spherical structure portion 31 is the core structure for realizing rotation in the wire-passing joint. The spherical structure portion 31 is provided at one end of the rotating member 3 for rotation and is located at the rotation limit Between the positioning member 2 and the mounting shell 4, the spherical structure portion 31 contacts the arc-shaped inner cavity 21 and the mounting limit opening 41, the arc-shaped inner cavity 21 and the mounting shell 4 cover each other to form a space for accommodating the spherical structure portion 31, the arc-shaped inner cavity 21 and the mounting shell 4 clamp the spherical structure portion 31 to limit the shaking position of the spherical structure portion 31 without affecting the rotation of the rotating member 3, the surface of the spherical structure portion 31 is in sliding contact with the surface of the arc-shaped inner cavity 21, and the limit column 32 extends into the limit groove 22 so that the rotating limit member 2 limits the rotation range of the rotating member 3, thereby preventing the rotating member 3 from squeezing the cable due to the wire hole 5 due to excessive rotation range, and controlling the rotation range within the range that satisfies the cable passing and activity space.

[0034] Specifically, in some embodiments, the main wire passing hole 5 is a through hole for allowing the cable to pass through. The main wire passing holes 5 are respectively arranged on the wire passing base 1, the rotating limit member 2 and the rotating member 3 to form wire passing holes that are connected to each other. The main wire passing holes 5 include a first wire passing hole 51 located on the wire passing base 1, a second wire passing hole 52 located on the rotating limit member 2, and a third wire passing hole 53 located on the rotating member 3. The design of multiple wire passing holes is conducive to having enough space for the cables to pass through, avoiding squeezing and cutting of the cables, helping to protect the stable placement of the cables, and improving the durability of the cables.

[0035] The utility model discloses a joint structure which is used for protecting cables and can greatly twist its direction to meet installation requirements. A wire-passing base and a spherical structure part of a mounting shell clamping a rotating part are adopted as a rotation mode for facilitating steering. A rotation limiter for limiting the steering range is arranged inside the wire-passing base, and a plurality of wire-passing holes for facilitating the passage of cables are opened on the wire-threading joint, so that the cables can pass through stably without being squeezed and bent, and the structure of the external connection can be freely turned and twisted in a large range. In addition to meeting the rotation requirements, the cable can be protected, which is convenient for users to use and improves the safety of use.

[0036] like Figures 4 to 8 As shown, it also includes a rotating gasket 6, which is installed between the rotating limiter 2 and the mounting shell 4, and the rotating gasket 6 is provided with an arc-shaped contact surface 61 that contacts the surface of the spherical structure 31.

[0037] Optionally, in some embodiments, the rotating gasket 6 can be made of materials such as rubber, silicone, plastic or polymer materials. These materials have good wear resistance and elasticity, so that when the rotating gasket 6 contacts the spherical structure part 31 and generates friction, the service life of the rotating gasket 6 can be improved. It can also be attached to the spherical structure part 31 over a large area to improve the rotation stability of the spherical structure part 31. Preferably, the rotating gasket 6 is made of silicone material. Among the above materials, silicone has better wear resistance and elasticity, is easy to make, has low procurement cost, and is convenient for production.

[0038] Specifically, in some embodiments, the rotating gasket 6 is a protective gasket that is placed between the spherical structure part 31, the rotating limit member 2 and the mounting shell 4 to avoid direct contact between the three. The rotating limit member 2 and the mounting shell 4 are respectively provided with a gasket installation groove for installing and limiting the rotating gasket 6. The thickness of the rotating gasket 6 is greater than the depth of the gasket installation groove, so as to avoid contact and friction between the spherical structure part 31 and the arc-shaped inner cavity 21, and also avoid contact and friction between the spherical structure part 31 and the mounting shell 4, thereby improving the durability of the rotating limit member 2 and the mounting shell 4. The rotating gasket 6 elastically contacts and presses the spherical structure part 31 through the arc-shaped contact surface 61, so that the rotating member 3 will not shake easily when rotating, thereby improving the rotation stability of the rotating member 3.

[0039] like Figure 1 and Figure 2 as well as Figures 4 to 8 As shown, the other end of the rotating member 3 is provided with a connecting portion 33 for connecting to the outside, and the connecting portion 33 is provided with a limiting platform 34 for limiting the rotation direction of the rotating member.

[0040] Specifically, in some embodiments, the connecting portion 33 is a connecting part of the threading connector for outputting cables and connecting external structures or devices. The connecting portion 33 is provided with a built-in assembly cavity and a plurality of assembly holes located in the assembly cavity for easy installation. Adding a connecting portion 33 to the threading connector can facilitate the connection of the threading connector to other structures or devices. The connection with other structures or devices is reinforced through the assembly holes to avoid shaking or collision during connection that may cause easy loosening. A limiting platform 34 is provided on the outer side of the connecting portion 33 for limiting the rotation direction of other external structures or devices. The limiting platform 34 is provided with a flat and smooth platform surface. When other external structures or devices are connected to the rotating part 3 through the connecting portion 33, the clamping limiting platform 34 can be used to make the other external structures or devices rotate synchronously with the rotating part 3, thereby avoiding the assembly hole directly bearing the torque of rotation and causing easy damage, reducing the friction between the external structure or device and the connecting portion 33, improving the durability of the rotating part 3, and improving the rotation stability of the rotating part 3.

[0041] like Figures 1 to 8 As shown, the end of the wire passing base 1 away from the rotation limiter 2 is provided with a base mounting portion 11 for connecting to the outside, and the main wire passing hole 5 includes a side wire passing hole 54 located on the base mounting portion 11.

[0042] Specifically, in some embodiments, the base mounting portion 11 is a plug for inserting into other external structures or devices. After the base mounting portion 11 is connected to the outside, the rotating member 3 can make a relatively stable rotation relative to the other external structures or devices. The base mounting portion 11 is symmetrically arranged at one end of the wire-passing base 1 away from the rotation limit member 2. The main wire-passing hole 5 includes a side wire-passing hole 54 for passing the cable. The side wire-passing hole 54 is located between two symmetrically arranged base mounting portions 11. The side wire-passing hole 54 is connected to the interior of the wire-passing base 1 and leads to the first wire-passing hole 51 and the second wire-passing hole 52. The design of the side wire-passing hole 54 can facilitate users to pass cables from different wire-passing holes respectively, which helps cables extending in different directions to pass through the wire-passing connector, thereby improving the practicality and adaptability of the wire-passing connector.

[0043] like Figures 4 to 8 As shown, the wire passing base 1 is provided with a base positioning portion 13, the mounting shell 4 is provided with a shell positioning portion 42, and the shell positioning portion 42 is provided with a positioning blind hole 43 for the base positioning portion 13 to extend into.

[0044] Specifically, in some embodiments, the base positioning portion 13 is a hollow positioning column extending from the base inner cavity wall of the wire-passing base 1 and used to limit the installation position of the wire-passing base 1. The shell positioning portion 42 is a hollow positioning column extending from the shell inner cavity wall of the mounting shell 4 and used to limit the installation position of the mounting shell 4. The shell positioning portion 42 is provided with a positioning blind hole 43 for the base positioning portion 13 to extend into. The base positioning portion 13 extends into the positioning blind hole 43 so that the base positioning portion 13 is connected with the shell positioning portion 42 by a clearance fit. The relative position of the wire-passing base 1 and the mounting shell 4 is defined by the clearance fit between the columnar outer wall and the hole wall, so that the installation accuracy of the wire-passing base 1 and the mounting shell 4 is relatively high, avoiding shaking caused by excessive clearance that affects use, and improving the rotation stability of the threading connector.

[0045] like Figures 4 to 8 As shown, it also includes a fastener for installation, and the fastener passes through the wire-passing base 1 and the rotation limiter 2 and is detachably connected to the installation housing 4. The wire-passing base 1 is provided with a first installation portion 14 for the fastener to pass through, and the rotation limiter 2 is provided with a second installation portion 23 corresponding to the first installation portion 14.

[0046] Optionally, in some embodiments, the fasteners may be various fastening accessories such as screws, bolts, pins, rivets, etc. Preferably, the fasteners may be bolts or screws as fastening accessories, and the bolts or screws have a threaded structure for convenient connection. The wire passing device 1 may be threadedly connected to the mounting housing 4 through the threaded structure and clamp the spherical structure portion 31, so that the rotating member 3 is more stable when rotating.

[0047] Specifically, in some embodiments, the first mounting portion 14 passes through the wire passing base 1 and is arranged around the first wire passing hole 51, the second mounting portion 23 passes through the rotation limit member 2 and is arranged around the second wire passing hole 52, and the first mounting portion 14 and the second mounting portion 23 are both used for fasteners to pass through and lock in the mounting shell 4, so that the wire passing base 1, the rotation limit member 2 and the mounting shell 4 are stably and detachably connected. After the rotation limit member 2 and the mounting shell 4 clamp the spherical structure portion 31, they are locked by fasteners and the degree of locking is adjusted, so that the spherical structure portion 31 meets the requirements of stable rotation and will not shake easily, thereby improving the stability of the wire threading joint.

[0048] like Figures 5 to 8 As shown, the mounting shell 4 is provided with a third mounting portion 44 for connecting the fastener, and the second mounting portion 23 is provided with a mounting limiting cavity 231 for the third mounting portion 44 to extend into.

[0049] Specifically, in some embodiments, the mounting shell 4 is provided with a third mounting portion 44 for detachably connecting a fastener, and the fastener passes through the first mounting portion 14 and the second mounting portion 23 and then extends into the third mounting portion 44 for threaded connection. The tightness of the spherical structure portion 31 clamped by the rotation limit member 2 and the mounting shell 4 is adjusted through the threaded connection, so that the spherical structure portion 31 meets the requirement of stable rotation and does not shake easily. The second mounting portion 23 is provided with a mounting limit cavity 231 for the third mounting portion 44 to extend into, and the third mounting portion 44 extends into the mounting limit cavity 231 with a clearance fit, so that the rotation limit member 2 is stably installed in the mounting shell 4, avoiding shaking or displacement of the rotation limit member 2 during use to affect the use of the rotating member 3, and multiple fasteners are respectively passed through multiple first mounting portions 14 and second mounting portions 23 and installed in the third mounting portion 44, so that the overall structure of the threading joint is more stable, thereby improving the structural stability of the threading joint.

[0050] like Figure 1 as well as Figures 3 to 8 As shown, a plurality of the first mounting portions 14 are arranged at intervals around the circumference of the main cable hole 5 .

[0051] Specifically, in some embodiments, multiple first mounting portions 14 are arranged at annular circumferential intervals around the first wire passing hole 51 on a side of the wire passing base 1 away from the rotating member 3. Correspondingly, the same number of multiple second mounting portions 23 are also arranged at annular circumferential intervals on the rotation limit member 2 corresponding to the multiple first mounting portions 14. Correspondingly, the same number of multiple third mounting portions 44 are also arranged at annular circumferential intervals on the mounting shell 4 corresponding to the multiple second mounting portions 23. The second mounting portion 23 and the third mounting portion 44 corresponding to each first mounting portion 14 are in a coaxial state to facilitate the fastener to pass through and connect to the third mounting portion 44. Such a design helps the wire passing base 1, the rotation limit member 2 and the mounting shell 4 to disperse the clamping force through the first mounting portions 14, the second mounting portions 23 and the third mounting portions 44 that are evenly arranged when clamping the rotating member 3, so that the rotating member 3 is evenly stressed in multiple directions, avoiding the force point being biased towards the weak side to affect the rotation and durability, and the overall structure of the threading joint is more stable, thereby improving the structural stability of the threading joint.

[0052] like Figures 6 to 8 As shown, a reinforcing rib 232 for reinforcing the second mounting portion 23 is provided on the outer side of the rotation limiting member 2 .

[0053] Specifically, in some embodiments, the rotation limiter 2, as a component installed between the wire-passing base 1 and the mounting shell 4 to directly clamp the rotation member 3, is subjected to the largest shaking force. In order to improve the bearing capacity of the rotation limiter 2, a reinforcing rib 232 for strengthening the force is additionally provided between the second mounting portion 23 and the second wire-passing hole 52, and reinforcing ribs 232 are evenly provided between multiple second mounting portions 23 and the second wire-passing holes 52. Such a design helps to improve the shaking force of the rotation limiter 2, avoid damage and cracks at the connection between the second mounting portion 23 and the rotation limiter 2 during use, and improve the structural stability of the rotation limiter 2.

[0054] like Figures 1 to 8 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0055] During installation, the rotation limiter 2 is placed in the base cavity of the wire-passing base 1, the second mounting portion 23 is aligned with the first mounting portion 14, the rotation member 3 is placed in the arc-shaped cavity 21 so that the spherical structure portion 31 fits with the arc-shaped cavity 21, and after the limiting column 32 is inserted into the limiting groove 22, the connecting portion 33 passes through the installation limiting opening 41, the installation shell 4 covers the rotation member 3 and extends the base positioning portion 13 into the shell positioning portion 42, the base positioning portion 13 and the positioning blind hole 43 are clearance-matched, so that the third mounting portion 44 is aligned with the second mounting portion 23, and then the fastener is passed through the first mounting portion 14 and the second mounting portion 23 and is threadedly connected to the third mounting portion 44, and the clamping tightness of the rotation member 3 is adjusted by the threaded connection between the fastener and the third mounting portion 44 to complete the installation of the threading connector;

[0056] When in use, the cable is inserted into the first wire hole 51 and passes through the second wire hole 52 and the third wire hole 53 to reach the connecting part 33, and can be connected to other structures or equipment. When rotating, the limit groove 22 limits the range of movement of the limit column 32 so that the rotating member 3 is within the preset rotation range. When the rotating member 3 rotates, it drives the cable to bend and turn in the direction of rotation.

[0057] like Figures 1 to 8 As shown, the specific implementation of Example 2 of the utility model is as follows:

[0058] Different from the first embodiment, the cables of this embodiment can be inserted through the side wire hole 54;

[0059] When in use, the cable is extended into the side wire hole 54 and passes through the second wire hole 52 and the third wire hole 53 to reach the connecting part 33, and can be connected to other structures or equipment. When rotating, the limit groove 22 limits the range of movement of the limit column 32 so that the rotating member 3 is within the preset rotation range. When the rotating member 3 rotates, it drives the cable to bend and turn in the direction of rotation.

[0060] like Figures 1 to 8As shown, the specific implementation of Example 3 of the utility model is as follows:

[0061] Different from the first and second embodiments, in the present embodiment, a rotating gasket 6 may be installed between the rotating stopper 2 and the mounting housing 4. The rotating gasket 6 elastically contacts and presses against the spherical structure 31 through the arc-shaped contact surface 61, so that the rotating member 3 does not shake easily when rotating, thereby improving the stability of the rotation of the rotating member 3.

[0062] The rotation limiter 2 and the mounting shell 4 are respectively provided with a gasket mounting groove for mounting and limiting the rotation gasket 6; during installation, the rotation limiter 2 is placed in the base inner cavity of the over-line base 1, the second mounting portion 23 is aligned with the first mounting portion 14, and after the rotation gasket 6 is installed in the gasket mounting groove of the rotation limiter 2, the rotation member 3 is placed in the arc-shaped inner cavity 21 so that the spherical structure portion 31 fits with the arc-shaped contact surface 61 of the rotation gasket 6, and after the limiting column 32 extends into the limiting groove 22, the connecting portion 33 passes through the mounting limiting opening 41, and the mounting shell The rotating member 3 and the rotating gasket 6 are covered so that the rotating gasket 6 is installed in the gasket installation groove of the installation housing 4, the base positioning portion 13 extends into the housing positioning portion 42, the base positioning portion 13 and the positioning blind hole 43 are clearance-matched, so that the third installation portion 44 is aligned with the second installation portion 23, and then the fastener is passed through the first installation portion 14 and the second installation portion 23 and is threadedly connected with the third installation portion 44, and the clamping tightness of the rotating member 3 is adjusted by the threaded connection between the fastener and the third installation portion 44, and the installation of the threading connector is completed;

[0063] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
