Description

Technical Field

[0001] This invention relates to the field of universal connector technology, and particularly to an adjustable universal connector and a cosmetic mirror. Background Technology

[0002] Makeup mirrors typically consist of a mounting bracket and a mirror. The mirror is mounted on the bracket via a universal connector, allowing users to flexibly adjust the mirror's angle as needed. In existing makeup mirrors, the universal connector usually includes a ball-and-socket joint on the back of the mirror and a ball joint connected to the mounting bracket. The ball-and-socket joint has a spherical movable cavity and a clearance hole communicating with the movable cavity. The ball joint passes through the clearance hole, and its ball head is movably mounted within the movable cavity. The ball joint can rotate omnidirectionally relative to the ball-and-socket joint, and the clearance hole limits the range of rotation of the ball joint relative to the ball-and-socket joint. In this type of universal connector, the ball-and-socket joint and the ball head are usually interference-fitted, creating a damping force between them. This damping force allows the mirror to stop at the desired angle. However, after a period of use, the ball-and-socket joint and the ball head will wear down, causing the damping force between them to decrease, making the universal connector loose and preventing the mirror from stopping at the desired angle. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an adjustable tension universal connector, which can adjust the tension of the universal connector as needed, and the adjustment is convenient.

[0004] The present invention also proposes a cosmetic mirror having the above-mentioned universal connector.

[0005] An adjustable universal connector according to a first aspect of the present invention includes a base, a locking sleeve, a first mounting pad, a second mounting pad, and a ball joint. One end of the locking sleeve is screwed to the base. One end of the locking sleeve has an open receiving cavity, and the other end has a first clearance hole communicating with the receiving cavity. The first mounting pad is mounted on the base and located within the receiving cavity. The second mounting pad is disposed within the receiving cavity and located on the side of the first mounting pad away from the base. A space is provided between the first mounting pad and the second mounting pad to restrict their relative deflection. The positioning structure includes a spherical movable cavity formed by the first mounting pad and the second mounting pad, wherein the second mounting pad is provided with a second clearance hole communicating with the movable cavity and the first clearance hole; the ball joint passes through the first clearance hole and the second clearance hole, one end of the ball joint is a ball head, the ball head is movably mounted in the movable cavity, and the ball head abuts against the first mounting pad and the second mounting pad; wherein, when the locking sleeve rotates relative to the base, the locking sleeve can enable the first mounting pad and the second mounting pad to cooperate to clamp or release the ball head.

[0006] The adjustable tension universal connector according to embodiments of the present invention has at least the following beneficial effects: With the above-described configuration, the universal connector provided by the present invention only requires the locking sleeve to rotate relative to the base to allow the first mounting pad and the second mounting pad to cooperate in clamping or releasing the ball joint, thereby realizing the tension adjustment of the universal connector, which is convenient. Furthermore, since a positioning structure is provided between the first mounting pad and the second mounting pad to limit their relative deflection, the first mounting pad and the second mounting pad remain relatively stationary during the rotation of the ball joint relative to the base. This makes the ball joint more stable during rotation and prevents misalignment of the first mounting pad and the second mounting pad from causing a failure in the fit, ensuring that the first mounting pad and the second mounting pad can effectively cooperate in clamping the ball joint during the rotation of the ball joint.

[0007] According to some embodiments of the present invention, the positioning structure includes a plurality of first elastic clamping teeth disposed on the first mounting pad and a plurality of second elastic clamping teeth disposed on the second mounting pad. All the first elastic clamping teeth are arranged circumferentially along the first mounting pad and abut against the ball head. Adjacent two first elastic clamping teeth form a first slot. The second elastic clamping teeth are arranged circumferentially along the second mounting pad and abut against the ball head. All the second elastic clamping teeth are correspondingly embedded in all the first slots.

[0008] According to some embodiments of the present invention, one side of the first elastic clamping tooth is an arc surface and fits against the surface of the ball head, and one side of the second elastic clamping tooth is an arc surface and fits against the surface of the ball head.

[0009] According to some embodiments of the present invention, there is a gap between the bottom surface of the first slot and the second elastic clamping tooth, and two adjacent second elastic clamping teeth surround to form a second slot for the corresponding first elastic clamping tooth to be inserted, and there is a gap between the bottom surface of the second slot and the first elastic clamping tooth.

[0010] According to some embodiments of the present invention, the base is provided with a positioning groove, and one end of the first mounting pad is embedded in the positioning groove.

[0011] According to some embodiments of the present invention, the peripheral wall of the second clearance hole protrudes to form a positioning part, the positioning part is inserted into the first clearance hole, and the outer periphery of the positioning part is in contact with the inner wall of the first clearance hole.

[0012] According to some embodiments of the present invention, the receiving cavity is cylindrical, and the outer contour of the second mounting pad near the first clearance hole is cylindrical to fit the receiving cavity.

[0013] According to some embodiments of the present invention, the ball joint includes a connecting arm at least partially located outside the locking sleeve, the connecting arm being detachably connected to the ball head.

[0014] A cosmetic mirror according to a second aspect of the present invention includes a mounting bracket, a mirror, and the aforementioned adjustable universal connector, wherein one of the base and the ball joint is connected to the mounting bracket, and the other is connected to the mirror.

[0015] According to an embodiment of the present invention, a cosmetic mirror has at least the following beneficial effects: by using the above-mentioned universal connector, when it is found that the mirror cannot stop at the required angle position, the locking sleeve can be rotated relative to the base to tighten the universal connector and increase the damping; when it is found that the mirror is difficult to rotate due to excessive damping, the locking sleeve can be rotated relative to the base to loosen the universal connector. Thus, the cosmetic mirror provided by the present invention can adjust the tightness of the universal connector as needed, and the adjustment is convenient.

[0028] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 4 According to an embodiment of the present invention, an adjustable universal connector includes a base 100, a locking sleeve 200, a first mounting pad 310, a second mounting pad 320, and a ball joint 400. One end of the locking sleeve 200 is screwed to the base 100. One end of the locking sleeve 200 is provided with an open receiving cavity 210, and the other end is provided with a first clearance hole 220 communicating with the receiving cavity 210. The first mounting pad 310 is mounted on the base 100 and located within the receiving cavity 210. The second mounting pad 320 is disposed within the receiving cavity 210 and located on the side of the first mounting pad 310 away from the base 100. A space is provided between the first mounting pad 310 and the second mounting pad 320 to limit their relative deflection. The positioning structure includes a first mounting pad 310 and a second mounting pad 320 forming a spherical movable cavity 330. The second mounting pad 320 is provided with a second clearance hole 321 that communicates with the movable cavity 330 and the first clearance hole 220. A ball joint 400 passes through the first clearance hole 220 and the second clearance hole 321. One end of the ball joint 400 is a ball head 410, which is movably mounted in the movable cavity 330 and abuts against the first mounting pad 310 and the second mounting pad 320. When the locking sleeve 200 rotates relative to the base 100, the locking sleeve 200 can make the first mounting pad 310 and the second mounting pad 320 cooperate to clamp or release the ball head 410.

[0030] With the above configuration, the universal connector provided by the present invention only requires the locking sleeve 200 to rotate relative to the base 100, so that the first mounting pad 310 and the second mounting pad 320 can cooperate to clamp or loosen the ball head 410, thereby realizing the tightness adjustment of the universal connector, and the adjustment is convenient. In particular, since a positioning structure is provided between the first mounting pad 310 and the second mounting pad 320 to limit their relative deflection, the first mounting pad 310 and the second mounting pad 320 remain relatively stationary during the rotation of the ball joint 400 relative to the base 100, making the ball joint 400 more stable during rotation and preventing the first mounting pad 310 and the second mounting pad 320 from being misaligned due to relative deflection, thus ensuring that the first mounting pad 310 and the second mounting pad 320 can effectively cooperate to clamp the ball head 410 during the rotation of the ball joint 400.

[0031] The universal connector provided by this invention can be applied to cosmetic mirrors and products with rotating components such as camera stands. Specifically, the universal connector provided by this invention, through its positioning structure, can prevent the ball joint 410 from becoming less accurate due to repeated relative misalignment between the first mounting pad 310 and the second mounting pad 320, thus ensuring the movement accuracy and stability of the ball joint 400 and meeting the high precision requirements of products such as camera stands.

[0032] Reference Figure 2 and Figure 3 As can be imagined, in some embodiments, the positioning structure includes a plurality of first elastic clamping teeth 311 disposed on the first mounting pad 310 and a plurality of second elastic clamping teeth 322 disposed on the second mounting pad 320. All the first elastic clamping teeth 311 are arranged circumferentially on the first mounting pad 310 and abut against the ball head 410. Adjacent two first elastic clamping teeth 311 form a first groove 312. The second elastic clamping teeth 322 are arranged circumferentially on the second mounting pad 320. Two elastic clamping teeth 322 abut against the ball head 410. All the second elastic clamping teeth 322 are correspondingly embedded in all the first slots 312. With the above arrangement, the relative deflection of the first mounting pad 310 and the second mounting pad 320 can be restricted by the cooperation of the first elastic clamping teeth 311 and the second elastic clamping teeth 322. In addition, the contact length between the first mounting pad 310 and the second mounting pad 320 and the ball head 410 is increased, so that the first mounting pad 310 and the second mounting pad 320 can clamp the ball head 410 more effectively.

[0033] During assembly, the first mounting pad 310 can be installed on the base 100 first, then the ball head 410 can be placed on the first mounting pad 310, then the second mounting pad 320 can be installed on the first mounting pad 310, and then the locking sleeve 200 can be screwed onto the base 100. The positioning structure can prevent the ball head 410 from being accidentally pushed out of the movable cavity 330 during the process of connecting the locking sleeve 200 to the base 100, which would lead to assembly errors.

[0034] Reference Figure 1 and Figure 2 It can be imagined that in some embodiments, one side of the first elastic clamping tooth 311 is an arc surface and fits against the surface of the ball head 410, and one side of the second elastic clamping tooth 322 is an arc surface and fits against the surface of the ball head 410. With the above configuration, the first elastic clamping tooth 311 and the second elastic clamping tooth 322 can guide and position the ball head 410 to further improve the movement accuracy of the ball joint 400.

[0035] Reference Figure 2 and Figure 3 It is conceivable that, in some embodiments, there is a gap between the bottom surface of the first slot 312 and the second elastic clamping tooth 322, so that the second elastic clamping tooth 322 can move during the tightening of the locking sleeve 200, thereby preventing the second elastic clamping tooth 322 from pressing against the first mounting pad 310 and affecting the clamping of the ball head 410. Two adjacent second elastic clamping teeth 322 surround to form a second slot 323 for the corresponding first elastic clamping tooth 311 to be inserted. There is a gap between the bottom surface of the second slot 323 and the first elastic clamping tooth 311, so that the first elastic clamping tooth 311 can move during the tightening of the locking sleeve 200, thereby preventing the first elastic clamping tooth 311 from pressing against the second mounting pad 320 and affecting the clamping of the ball head 410. With the above configuration, the first mounting pad 310 and the second mounting pad 320 can also compensate for errors according to the actual size of the ball head 410, ensuring that the first mounting pad 310 and the second mounting pad 320 can effectively clamp the ball head 410 with dimensional errors.

[0036] It should be noted that the above positioning structure can also adopt other settings. For example, the positioning structure includes a regular hexagonal groove and an annular protrusion with a regular hexagonal outer contour. The annular protrusion is set on the first mounting pad 310, and the inner side of the annular protrusion can fit against the surface of the ball head 410. The groove is set on the second mounting pad 320, and the annular protrusion is engaged in the groove.

[0037] Reference Figure 1 and Figure 2As can be imagined, in some embodiments, the base 100 is provided with a positioning groove 110, and one end of the first mounting pad 310 is embedded in the positioning groove 110. With the above arrangement, the base 100 can position the first mounting pad 310 to prevent the first mounting pad 310 from tilting or swinging relative to the base 100 during the rotation of the ball head 410.

[0038] It should be noted that in some other embodiments, the first mounting pad 310 may also be mounted on the base 100 in other ways, for example, the first mounting pad 310 may be mounted on the base 100 by bolts.

[0039] Reference Figure 1 and Figure 2 As can be imagined, in some embodiments, the peripheral wall of the second clearance hole 321 protrudes to form a positioning part 324. The positioning part 324 is inserted into the first clearance hole 220, and the outer periphery of the positioning part 324 fits against the inner wall of the first clearance hole 220. Thus, the second mounting pad 320 can be positioned by the cooperation between the positioning part 324 and the first clearance hole 220, preventing the second mounting pad 320 from tilting or swinging relative to the locking sleeve 200 during the rotation of the ball head 410.

[0040] Reference Figure 1 and Figure 2 As can be imagined, in some embodiments, the receiving cavity 210 is cylindrical, and the outer contour of the end of the second mounting pad 320 near the first clearance hole 220 is cylindrical and adapted to the receiving cavity 210. Thus, the receiving cavity 210 can guide and position the second mounting pad 320, ensuring the installation accuracy of the second mounting pad 320. Furthermore, during installation, simply inserting the second mounting pad 320 into the receiving cavity 210 along its axis and inserting the positioning part 324 into the first clearance hole 220 is sufficient to position the second mounting pad 320; the positioning process is relatively simple.

[0041] Reference Figure 1 and Figure 2 As can be imagined, in some embodiments, the ball joint 400 includes a connecting arm 420 at least partially located outside the locking sleeve 200. The connecting arm 420 is detachably connected to the ball head 410. Thus, during assembly, the ball head 410 can be first installed in the movable cavity 330, then the locking sleeve 200 can be screwed to the base 100, and finally the connecting arm 420 can be connected to the ball head 410, simplifying the assembly process. Furthermore, connecting arms 420 of different lengths can be replaced as needed.

[0042] In practice, the connecting arm 420 can be detachably connected to the ball head 410 through snap-fit, threaded connection or other means.

[0043] It is conceivable that in some embodiments, the first mounting pad 310 is connected to the base 100, and a limiting structure is provided between the first mounting pad 310 and the second mounting pad 320 to restrict the second mounting pad 320 from disengaging from the first mounting pad 310. The connecting arm 420 is provided with a limiting part 421, which is located outside the locking sleeve 200. The width of the limiting part 421 is greater than the diameter of the first clearance hole 220, and the length of the locking sleeve 200 is greater than the distance between the limiting part 421 and the base 100. With the above arrangement, the limiting structure can limit the movement of the second mounting pad 320 during the loosening of the locking sleeve 200. The second mounting pad 320 is disengaged from the first mounting pad 310, thereby preventing the ball head 410 from disengaging from the movable cavity 330. In this way, when the locking sleeve 200 contacts the limiting part 421, the locking sleeve 200 is still screwed to the base 100. The limiting part 421 can prevent the locking sleeve 200 from being loosened further, thereby reducing the possibility that the locking sleeve 200 will accidentally detach from the base 100 due to excessive loosening by the user. This can further reduce the possibility that the makeup mirror 600 will accidentally fall off the mounting bracket 500, causing damage to the mirror 600 or injuring the user. The safety is high.

[0044] Specifically, in some embodiments, the limiting structure includes a protrusion and a limiting groove. One of the buckle and the limiting groove is disposed on the first elastic clamping tooth 311, and the other is disposed on the side wall of the corresponding second slot 323. The protrusion is slidably inserted into the limiting groove.

[0045] Specifically, in some embodiments, a retaining ring is provided at one end of the first mounting pad 310, and an annular retaining groove is provided on the inner wall of the first positioning groove 110. The retaining ring is engaged in the retaining groove, thereby engaging the first mounting pad 310 with the base 100.

[0046] Reference Figure 1 According to an embodiment of the present invention, a cosmetic mirror includes a mounting bracket 500, a mirror 600, and the aforementioned adjustable universal connector. One of the base 100 and the ball joint 400 is connected to the mounting bracket 500, and the other is connected to the mirror 600. By employing the aforementioned universal connector, when the mirror 600 cannot be stopped at the desired angle, the locking sleeve 200 can be rotated relative to the base 100 to tighten the universal connector and increase damping. When the mirror 600 is found to have difficulty rotating due to excessive damping, the locking sleeve 200 can be rotated relative to the base 100 to loosen the universal connector. Thus, the cosmetic mirror provided by the present invention can adjust the tightness of the universal connector as needed, and the adjustment is convenient.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
