Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic products, and more specifically to an internal wiring belt positioning anti-hinge ball head structure and a lamp. Background Art
[0002] As one of the rotational connection methods, ball joints can achieve arbitrary rotation within a range of 360 degrees, greatly improving the rotation range of the product. However, for electronic products that require wires to be built into the ball head for routing, if the 360-degree rotation range is still maintained, it is very easy to cause wire kinking, that is, excessive bending of the wires, resulting in fatigue fracture of the wires, causing the electronic product to fail and greatly shortening its service life. Utility Model Content
[0003] The purpose of the present utility model is to overcome the deficiency of the prior art in that the wiring inside the ball hinge structure easily causes the hinge to break, and to provide an internal wiring with a positioning anti-hinge ball head structure and a lamp, which can limit the rotation angle of the ball hinge to a certain extent, so that it can be greater than the rotation angle of the ordinary shaft transfer and prevent the hinge from breaking, thereby increasing the practicality of the wiring inside the ball head structure and improving the aesthetics of the electronic product.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0005] Provided is an internal wiring belt positioning and anti-hinge ball head structure, comprising a first joint, a second joint, and a mounting seat, all of which are provided with open cavities, and also a rotating shaft. The outside and inside of the first joint, as well as the outside of the second joint and the inside of the mounting seat are all provided with spherical rotating surfaces. The first joint and the second joint are concentrically arranged and are both movably mounted on the mounting seat. The first joint is sleeved on the outside of the second joint and is rotatably connected to the second joint through the rotating shaft; the second joint is provided with a first limiting groove, and the rotating shaft is located in the first limiting groove; the second joint is provided with a first limiting portion, and the mounting seat is provided with a second limiting portion, and the first limiting portion is slidably connected to the second limiting portion.
[0006] The present invention routes the wires internally by passing them through the first connector, the second connector, and the mounting seat in sequence, and at the same time, the first connector and the second connector are rotatably connected by a rotating shaft, so that the first connector can rotate relative to the second connector around the rotating shaft with the rotating shaft as the axis, which is the first direction of limitation; further, by setting a first limiting groove, the rotating shaft can swing along the first limiting groove, so that the first connector and the second connector can cooperate with the rotating shaft to rotate along the three-dimensional space where the first limiting groove is located, which is the second direction of limitation; further, by the sliding connection between the first limiting part and the second limiting part, the first connector and the second connector can cooperate with the rotating shaft to rotate along the sliding direction of the first limiting part and the second limiting part, which is the third direction of limitation. Under the above three direction limitations, the wire inside the ball head can only be bent at a certain angle, and cannot be bent 360 degrees without restriction, so the hinge wire can be prevented from breaking, ensuring the service life of the wire, thereby improving the service life of the electronic product.
[0007] Preferably, the first limiting groove is an arc-shaped structure, and the arc is arranged concentrically with the spherical rotating surface. The bottom of the first joint and the top and bottom of the second joint are open structures to facilitate the passage of wires. The first joint and the second joint cooperate with the rotating shaft to rotate along the arc of the first limiting groove.
[0008] Preferably, the first limit groove also extends through the top of the second joint, defining a line vertically passing through the center of the spherical rotating surface as the centerline of the ball head structure. The first limit grooves are symmetrically arranged on the second joint along this centerline. By limiting the arc corresponding to the arc structure of the first limit groove, the swing angle of the first and second joints can be limited. The symmetrical arrangement of the first limit grooves along the centerline ensures that the swing amplitude meets practical requirements during the swing process.
[0009] Preferably, the first limiting portion is a protrusion located at the bottom of the second joint, and the second limiting portion is an arc-shaped groove. The protrusion and groove are slidably connected, and when the first limiting portion slides relative to the second limiting portion, the first joint and the second joint cooperate with the rotating shaft to rotate along the arc of the second limiting portion.
[0010] Preferably, the mounting base includes a limit bracket and an adjustment sleeve, both of which are hollow. The limit bracket has a plurality of adjustment slots uniformly distributed along the circumference thereof and extending therethrough. The first joint and the second joint are both mounted within the limit bracket, and the adjustment sleeve is sleeved on the outside of the limit bracket and threadedly connected thereto. By providing the adjustment slots, one end of the limit bracket is divided into a plurality of sections, all of which are connected at the other end, which is equivalent to making the size of the limit bracket adjustable. The width of the adjustment slot is indirectly set by the threaded engagement of the adjustment sleeve and the limit bracket. After the second joint is placed in the limit bracket, the width of the adjustment slot is reduced by tightening the adjustment sleeve and the limit bracket, thereby reducing the size of the limit bracket, thereby forming a wrapping limit for the second joint, and thus enabling the second joint to be securely installed.
[0011] Preferably, the lamp body connecting assembly is further included, and the lamp body connecting assembly is detachably mounted on the bottom of the mounting base and is used to connect the mounting base to the lamp body.
[0012] Preferably, the lamp body connection assembly includes an upper cover and a lower cover, the limit bracket is installed in the upper cover and is clamped thereto, and the lower cover is clamped to the upper cover. The upper cover is used to connect to the mounting base, specifically by clamping with the limit bracket, and the lower cover is used to connect to the lamp body.
[0013] Preferably, the first joint includes a first ball head with a spherical rotating surface and a rod connection portion, the rod connection portion being connected to the top of the first ball head portion. The first ball head portion is sleeved on the outside of the second joint, and the rod connection portion protrudes from the mounting seat. The first ball head portion is used to transfer to the second joint, and the rod connection portion is used to connect to the outside world.
[0014] Preferably, the second joint includes a second ball head with a spherical rotating surface and a seating portion, the seating portion being connected to the bottom of the second ball head, the first limiting portion being located at the bottom of the seating portion, and the seating portion being slidably connected to the mounting seat. The second ball head is used to connect to the first joint, and the seating portion is used to connect to the outside world.
[0015] The utility model also provides a lamp comprising a lamp post, the aforementioned internal wiring strip positioning anti-hinge ball joint structure, and a lamp body, wherein one end of the ball joint structure is connected to the lamp post and the other end is connected to the lamp body. The lamp is rotatably connected to the lamp body via the ball joint structure, allowing rotation within a wide range of angles while preventing internal wires from being scissored.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] The utility model can limit the rotation angle of the ball hinge to a certain extent, so that it can be greater than the rotation angle of the ordinary shaft transfer, and can prevent the hinge line from breaking, thereby increasing the practicality of the internal wiring of the ball head structure and improving the aesthetics of the electronic product.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0040] Example 1
[0041] like Figures 1 to 15 The figure shows a first embodiment of the utility model, which is a positioning anti-hinge ball head structure for internal wiring belt, including a first joint 1, a second joint 2, and a mounting seat 3, all of which are provided with open cavities, and also includes a rotating shaft 4. The outside and inside of the first joint 1 and the outside of the second joint 2 and the inside of the mounting seat 3 are provided with spherical rotating surfaces. The first joint 1 and the second joint 2 are concentrically arranged and are both movably mounted on the mounting seat 3. The first joint 1 is sleeved on the outside of the second joint 2 and is rotatably connected to the second joint 2 through the rotating shaft 4; the second joint 2 is provided with a first limiting groove 21, and the rotating shaft 4 is located in the first limiting groove 21; the second joint 2 is provided with a first limiting portion 22, and the mounting seat 3 is provided with a second limiting portion 31, and the first limiting portion 22 is slidably connected to the second limiting portion 31.
[0042] like Figure 14 As shown, the wire 6 passes through the middle of the first joint 1, the second joint 2, and the mounting base 3, and the first joint 1 and the second joint 2 are installed and fastened using the mounting base 3. The first joint 1 and the second joint 2 are both provided with spherical rotating surfaces to form a ball hinge structure, and then the first joint 1 and the second joint 2 are rotatably connected through the rotating shaft 4, so that the first joint 1 can rotate relative to the second joint 2 around the rotating shaft 4 as the axis. This is the limit in the first direction. Figure 5 and Figure 6 As shown; further, by providing the first limiting groove 21, the shaft 4 can swing along the first limiting groove 21, so that the first joint 1 and the second joint 2 can cooperate with the shaft 4 to rotate along the three-dimensional space where the first limiting groove 21 is located. This is the second direction of the limit, as shown Figure 10 As shown; further, through the sliding connection between the first limiting portion 22 and the second limiting portion 31, the first joint 1 and the second joint 2 can cooperate with the shaft 4 to rotate along the sliding direction of the first limiting portion 22 and the second limiting portion 31, which is the third direction limit, as shown Figure 13 By making the first, second, and third directions perpendicular to each other, a rotation limit in three-dimensional space can be formed. However, each direction has limitations, so it cannot achieve 360-degree rotation at any angle like a ball joint. Each direction can only rotate within a certain angle range, greatly reducing the risk of wire 6 being broken.
[0043] As an embodiment of the present invention, the first limiting groove 21 is an arc-shaped structure and the arc-shaped structure is arranged concentrically with the spherical rotating surface. The bottom of the first joint 1 and the top and bottom of the second joint 2 are all open structures to facilitate the passage of the wire 6. The first joint 1 and the second joint 2 cooperate with the rotating shaft 4 to rotate along the arc direction of the first limiting groove 21. This embodiment is based on the fact that the rotating shaft 4 passes through the first joint 1 and the second joint 2 horizontally from the center of the sphere. At this time, the first limiting groove 21 is arranged along the vertical plane passing through the axis of the rotating shaft 4, so that the rotating shaft 4 and the first limiting groove 21 can be limited in two different directions respectively, namely, rotation centered along the axis of the horizontally arranged rotating shaft 4, and longitudinal rotation along the center of the sphere to make the horizontal axis swing left and right. By setting the curvature corresponding to the arc structure of the first limiting groove 21 accordingly, the rotation angle of the first joint 1 and the second joint 2 can be limited, preferably to 180°~260°.
[0044] In one embodiment of the present invention, the first retaining groove 21 also extends through the top of the second joint 2. The centerline of the spherical head structure is defined as the line vertically passing through the center of the spherical rotating surface. The first retaining grooves 21 are symmetrically arranged along this centerline on the second joint 2. Because the top of the second joint 2 is open, if the arc structure corresponding to the first retaining groove 21 is large, the first retaining groove 21 is forced to be interrupted, divided into two sides by the centerline, but this does not affect the retaining function of the first retaining groove 21.
[0045] In one embodiment of the present invention, the first stopper 22 is a protrusion located at the bottom of the second joint 2, while the second stopper 31 is an arc-shaped groove. The stopper formed by the first and second stopper 22 and 31 is located horizontally, allowing the first joint 1 and the second joint 2 to rotate synchronously along the horizontal direction, about the centerline passing through the center of the sphere as the rotation axis 4. By adjusting the arc angle of the second stopper 31, the rotation angle of the first and second joints 1 and 2 can be limited, preferably to 180° to 260°.
[0046] As one embodiment of the present invention, the mounting base 3 includes a hollow limit bracket 32 and an adjustment sleeve 33. The limit bracket 32 is uniformly distributed along the circumference thereof with a plurality of adjustment slots 331 extending therethrough. The first joint 1 and the second joint 2 are both mounted within the limit bracket 32, and the adjustment sleeve 33 is sleeved on the outside of the limit bracket 32 and threadedly connected thereto. The provision of the adjustment slots 331 allows the limit bracket 32 to adjust its diameter under the action of the adjustment sleeve 33. As needed, the number of threads of the adjustment sleeve 33 and the limit bracket 32 is determined by the number of threads of connection. The tighter the adjustment sleeve 33 is screwed to the limit bracket 32, the smaller the diameter of the limit bracket 32, and the smaller the width of the adjustment slots 331. The looser the adjustment sleeve 33 is screwed to the limit bracket 32, the larger the diameter of the limit bracket 32, and the wider the adjustment slots 331.
[0047] As an embodiment of the present invention, the first joint 1 includes a first ball head 11 with a spherical rotating surface, a rod connecting portion 12, the rod connecting portion 12 is connected to the top of the first ball head 11, the first ball head 11 is sleeved on the outside of the second joint 2, and the rod connecting portion 12 is protruding from the mounting seat 3. The second joint 2 includes a second ball head 23 with a spherical rotating surface and a seat connecting portion 24, the seat connecting portion 24 is connected to the bottom of the second ball head 23, the first limiting portion 22 is located at the bottom of the seat connecting portion 24, and the seat connecting portion 24 is slidably connected to the mounting seat 3. The rod connecting portion 12 is used to connect to the outside world from the side of the first joint 1, and the seat connecting portion 24 is used to connect to the outside world from the side of the second joint 2. The first ball head 11 cooperates with the second ball head 23 to realize a ball hinge. Within the scope of knowledge of those skilled in the art, the ball head can be a structure similar to a ball head. In order to facilitate internal wiring, the top and bottom of the ball head can also be adaptively flattened to form an open structure that passes through from top to bottom, so that the wire 6 can pass through easily.
[0048] Example 2
[0049] The following is a second embodiment of the present invention's internal wiring belt positioning anti-hinge ball head structure. This embodiment is similar to the first embodiment, except that it further includes a lamp body connection assembly 5, which is detachably mounted on the bottom of the mounting base 3. The lamp body connection assembly 5 is used to connect the lamp body, allowing the ball head structure to establish contact with the lamp body.
[0050] As one embodiment of the present invention, the lamp body connection assembly 5 includes an upper cover 51 and a lower cover 52. The limit bracket 32 is installed in the upper cover 51 and is clamped thereto, and the lower cover 52 is clamped to the upper cover 51. The upper cover 51 is used to connect to the mounting base 3, specifically by clamping with the limit bracket 32, and the lower cover 52 is used to connect to the lamp body.
[0051] Example 3
[0052] like Figures 16 to 18 The figure shows an embodiment of a lamp of the present invention, comprising a lamp post 101, a ball-joint structure 102 with an internal wiring arrangement and positioning to prevent hinges, as described above, and a lamp body 103. The ball-joint structure 102 is connected to the lamp post 101 at one end and to the lamp body 103 at the other. The lamp is pivotally connected to the lamp body 103 via the ball-joint structure 102, and is also connected to the lamp post 101. This allows the lamp body 103 to rotate relative to the lamp post 101 over a wide range of angles while preventing the internal wires 6 from being hinged.
[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
