After the female head 31 and the male head support bowl 321 are matched, the female head 31 and the male head tooth plate 322 are detachably connected together to realize the installation of the projector and the bracket. There is no need to align the female head 31 and the male head 32, the operation is simpler, and the connection is more secure. When disassembly is required, the female head 31 and the male head tooth plate 322 are disassembled to realize the disassembly of the projector and the bracket. The joint structure 30 can be quickly installed and disassembled with the projector, which is more convenient to use and improves work efficiency.

[0039] Specifically, the female connector 31 may be integrated into the bottom of the projector, or the female connector 31 may be connected to the bottom of the projector via a 1 / 4 nut, which is not specifically limited here.

[0040] In this embodiment, the male support bowl 321 includes a support bowl body 3211 and a sleeve 3212, wherein the sleeve 3212 is disposed at the bottom of the support bowl body 3211, and the sleeve 3212 is sleeved at the end of the frame 20, and the bottom surface of the support bowl body 3211 contacts the end surface of the frame 20, and the female head 31 matches the support bowl body 3211.

The bottom of the connecting bowl 301 is provided with a plurality of through holes 3011, and the through holes 3011 are aligned with the through holes 3011 at the top of the frame 20. Bolts are passed through the through holes 3011 of the connecting bowl 301 and the through holes 3011 at the top of the frame 20 at the same time, thereby realizing a detachable connection between the joint and the frame 20. In other embodiments, the guide block 311 may be an upwardly protruding structure.

[0043] In this embodiment, the guide block 311 is a disc structure.

[0044] In this embodiment, the number of through holes 3011 is four. In other embodiments, the number of through holes 3011 may be increased or decreased, which is not specifically limited here.

[0045] In order to prevent the projector from easily moving relative to the bracket, an anti-skid structure is provided on the connecting bowl 301 and / or the guide block 311. In this embodiment, the side wall of the connecting bowl 301 and the side wall of the guide block 311 are both provided with an anti-skid structure. Of course, the anti-skid structure may be provided only on the side wall of the connecting bowl 301, or only on the side wall of the guide block 311.

[0046] The anti-skid structure in this embodiment is the anti-skid teeth 101. In other embodiments, the anti-skid structure may also be a friction anti-rotation structure, such as a structure for increasing friction, such as knurling, sandblasting, etc., which is not specifically limited here.

[0047] More preferably, part of the sidewalls of the guide block 311 are provided with anti-skid teeth 101. All the sidewalls of the connecting bowl 301 are provided with anti-skid teeth 101.

[0048] In order to improve the ease of use of the projector, a first power contact is provided in the connecting bowl 301, and a second power contact is provided in the female head 31. When the power adapter is set at the bottom of the base 10 and the guide block 311 is set in the connecting bowl 301, the first power contact and the second power contact are in contact, thereby realizing power conduction.

[0049] It should also be explained that the middle of the male toothed disc 322 is penetrated by a mounting hole 3221, the sleeve 3212 is arranged in the mounting hole 3221, and the bottom surface of the support bowl body 3211 is in contact with the top surface of the male toothed disc 322. The male toothed disc 322 is sleeved on the sleeve 3212, so as to achieve radial fixation, and the male toothed disc 322 can move and rotate axially along the male support bowl 321, so as to facilitate the placement of the female head 31 in the connecting bowl 301 at any angle, and lock the female head 31 by rotating. It is no longer necessary to align the female head 31 and the male toothed disc 322 before locking the female head 31, and the operation is simpler.

[0050] Specifically, the edge of the male tooth plate 322 is provided with a first tooth plate 3222, and the bottom surface of the female head 31 is provided with a second tooth plate 312. After the female head 31 is placed in the connection bowl 301, the female head 31 or the male tooth plate 322 is rotated so that the first tooth plate 3222 and the second tooth plate 312 are engaged. There are multiple second tooth plates 312, and the multiple second tooth plates 312 are arranged at intervals along the circumferential direction. There is a gap between two adjacent second tooth plates 312. After the female head 31 is placed in the connection bowl 301, if the first tooth plate 3222 is located in the gap, the female head 31 and the male head 32 are in a separated state. By rotating the male tooth plate 322, the first tooth plate 3222 passes over the gap and is engaged with the second tooth plate 312. At this time, the female head 31 and the male head 32 are in a locked state.

[0051] In addition, in order to prevent the male tooth plate 322 from rotating too much and to prevent the joint from being damaged, a limiting structure is provided on the first tooth plate 3222 or the second tooth plate 312. Specifically, a limiting block can be provided at the end of the second tooth plate 312, or a matching wedge structure can be provided on the surface where the male tooth plate 322 and the female head 31 are locked and combined, and the wedge structure is locked with each other to achieve limiting.

[0052] In addition, in order to improve the operating feel and to create a granular feel, the outer surface of the male toothed disc 322 has scale teeth.

[0053] Furthermore, the joint also includes an elastic member 40 and a lower cover plate 50. The lower cover plate 50 is sleeved on the end of the frame 20. The lower cover plate 50 is used to support the elastic member 40. The elastic member 40 is arranged between the male toothed disc 322 and the lower cover plate 50. The elastic member 40 is used to generate a reset torque to reset the male toothed disc 322.

[0054] In this embodiment, the elastic member 40 is a spring.

[0055] Specifically, the two ends of the spring are respectively abutted against the male toothed disc 322 and the lower cover plate 50, and the lower cover plate 50 provides a supporting force to the spring, so that the spring supports the male toothed disc 322 upward, thereby generating a reset torque, so that the first toothed disc 3222 of the male toothed disc 322 does not need to be aligned with the gap between the second toothed disc 312 of the female head 31 first, that is, the female head 31 can be placed in the male head 32 at any angle. When the first toothed disc 3222 and the gap are not aligned, after the female head 31 is placed in the male head 32, the female head 31 will force the male toothed disc 322 to move downward. It is only necessary to rotate the male toothed disc 322, and the first toothed disc 3222 can automatically enter the gap under the action of the elastic force of the spring. After continuing to rotate, the first toothed disc 3222 can be engaged with the second toothed disc 312.

[0056] It should also be noted that a motor can also be provided to realize the automatic locking operation of the female head 31 and the male head 32. After the guide block 311 and the connecting bowl 301 cooperate, the motor can be triggered automatically or manually to drive the female head 31 or the male head tooth plate 322 to rotate, thereby realizing the automatic locking operation.

[0057] In summary, an embodiment of the utility model provides a joint structure 30, which includes a female head 31 and a male head 32. The female head 31 is used to connect to the projector, and the male head 32 is used to connect to the top of the frame 20, or the female head 31 is connected to the top of the frame 20, and the male head 32 is used to connect to the projector. The male head 32 includes a male support bowl 321 and a male toothed disc 322. The male support bowl 321 is sleeved in the male toothed disc 322, and the male toothed disc 322 is used to move and rotate along the axial direction of the male support bowl 321. The female head 31 cooperates with the male support bowl 321 and is detachably connected to the male toothed disc 322. When the joint structure 30 is in use, the female head 31 and the projector are connected together, the male head support bowl 321 is sleeved in the male head tooth plate 322, and the male head tooth plate 322 can move and rotate along the axial direction of the male head support bowl 321. After the female head 31 and the male head support bowl 321 are matched, the female head 31 and the male head tooth plate 322 are detachably connected together to achieve the installation of the projector and the bracket. There is no need to align the female head 31 and the male head 32, the operation is simpler, and the connection is more secure.
