[0029] See Figure 1 and Figure 2 , or see Figure 3A gimbal of the present invention includes: a metal housing 100 having an upward-opening cavity 110; a plastic support 200 disposed within the cavity 110, having a first spherical groove 210 opposite to the opening of the cavity 110; a plastic clamping block 300 movably disposed within the metal housing 100, having a second spherical groove 310 opposite to the opening of the cavity 110; a metal ball head 400 disposed within the metal housing 100, the upper part of the metal ball head 400 being connected to a mounting platform 500 extending out of the opening of the cavity 110, the mounting platform 500 being used to connect photographic equipment; and a first locking member 600 threadedly connected to the side of the metal housing 100, one end of which extends into the metal housing 100 and is capable of pushing the plastic clamping block 300 close to the metal ball head 400, so that the metal ball head 400 abuts against the first spherical groove 210, the second spherical groove 310, and the inner wall of the metal housing 100.

[0030] The above-described gimbal utilizes the first spherical groove 210 on the plastic support 200 and the second spherical groove 310 on the plastic clamping block 300, together with the cavity 110 of the metal shell 100, to define the clamping space for clamping the metal ball head 400. The first locking member 600 pushes the plastic clamping block 300 to press the second spherical groove 310 against the surface of the metal ball head 400. The plastic support 200 and the plastic clamping block 300 can elastically deform to fit tightly against the surface of the metal ball head 400, so that the photographic equipment on the metal ball head 400 can be stably mounted on the gimbal. Moreover, the material cost of this gimbal is relatively low.

[0031] See Figure 1 and Figure 2 In some embodiments of the present invention, the lower end of the metal casing 100 is provided with a base 700 that can rotate relative to it about a vertical axis. A locking mechanism 800 is provided between the base 700 and the metal casing 100. The locking mechanism 800 has a locked state and an unlocked state. When the locking mechanism 800 is in the locked state, the base 700 is fixed to the metal casing 100. When the locking mechanism 800 is in the unlocked state, the base 700 can rotate relative to the metal casing 100. Using the above structure, the photographic equipment on the mounting platform 500 can be rotated horizontally. It should be noted that the base 700 is used to connect to a projection bracket or other fixed position. When it is necessary to rotate the photographic equipment horizontally, the locking mechanism 800 is first switched to the unlocked state, and then the base 700 can be driven to rotate relative to the metal casing 100. After adjustment, the locking mechanism 800 can be switched to the locked state.

[0032] See Figure 1 and Figure 2In some embodiments of the present invention, the interior of the metal housing 100 is provided with a mounting assembly 120 for fixing the plastic support 200. The mounting assembly 120 can drive the metal ball head 400 upward against the opening of the cavity 110. The base 700 has an upwardly extending pivot portion 710. The lower part of the plastic support 200 is provided with a sleeve portion 220 that cooperates with the pivot portion 710. The base 700 and the plastic support 200 are rotatably connected by a bolt assembly 10 coaxial with the pivot portion 710. It can be understood that the above structure uses the mounting assembly 120 to fix the plastic support 200 inside the metal housing 100, and then uses the bolt assembly 10 to rotatably connect the base 700 to the plastic support 200 to achieve the function of horizontal rotation of the base 700 relative to the metal housing 100, without the need for a rotatable connection structure between the base 700 and the metal housing 100. In addition, the cooperation between the pivot portion 710 and the sleeve portion 220 facilitates the limiting and guiding of the rotation of the base 700 relative to the plastic support 200.

[0033] See Figure 1 and Figure 2 In some embodiments of the present invention, the sleeve portion 220 has a second notch 221 arranged radially on its side. The locking mechanism 800 includes a plastic pressure block 810 movably disposed within the second notch 221 and a second locking member 820 threadedly connected to the metal housing 100. The second locking member 820 can push the plastic pressure block 810 to elastically abut against the pivot portion 710, thereby preventing the base 700 from rotating relative to the plastic support 200 and preventing the plastic support 200 from rotating relative to the metal housing 100. It is understood that when it is necessary to switch the locking mechanism 800 to the unlocked state, it is only necessary to rotate the second locking member 820 to remove the plastic pressure block 810 from pressing against the pivot portion 710; when it is necessary to switch the locking mechanism 800 to the locked state, it is only necessary to rotate the second locking member 820 to press the plastic pressure block 810 against the pivot portion 710. The above-mentioned locking mechanism 800 has a simple structure and is easy to use and operate.

[0034] See Figure 1 and Figure 2 In some embodiments of the present invention, the mounting assembly 120 includes a ring spring 121, the inner peripheral wall of the metal housing 100 is provided with an annular groove 122 for accommodating the ring spring 121, the plastic support 200 has a side plate portion located above the ring spring 121, the metal housing 100 is provided with an assembly 123 for driving the ring spring 121 to open and enter the annular groove 122 and press the side plate portion upward, the plastic pressure block 810 contacts the assembly 123 and stabilizes the assembly 123 within the metal housing 100, when the assembly 123 separates from the ring spring 121, the ring spring 121 retracts and leaves the annular groove 122 so that the plastic support 200 can detach from the metal housing 100.

[0035] It should be noted that the ring spring 121 generally has an opening. When assembling the gimbal with the above structure, the assembly 123 extends into the opening of the ring spring 121, opening the opening of the ring spring 121. At this time, a part of the ring spring 121 enters the annular groove 122, and a part of the ring spring 121 lifts the side plate upward, thereby fixing the plastic support 200 inside the metal shell 100. In this embodiment, the upper end face of the plastic pressure block 810 supports the lower end of the assembly 123 to prevent the assembly 123 from coming out of the opening of the ring spring 121. It can be understood that when the gimbal needs to be disassembled, the bolt assembly 10 can be unscrewed first, and then the base 700, plastic pressure block 810, second locking member 820, and assembly 123 can be removed in sequence. After that, the opening of the ring spring 121 closes, the ring spring 121 disengages from the annular groove 122, and the ring spring 121 and plastic support 200 can be removed.

[0036] See Figure 3 In some embodiments of the present invention, the lower end of the metal housing 100 is provided with a lower channel opening communicating with the cavity 110. A base 20 is detachably connected to the lower channel opening to fix the plastic support 200 inside the metal housing 100. The base 20 is provided with a downwardly extending threaded mounting post 21. The diameter of the threaded mounting post 21 is configured according to the usage requirements. The base 20 and the lower end of the metal housing 100 are connected by a threaded structure to close the lower channel opening, thereby stabilizing the plastic support 200 inside the metal housing 100.

[0037] See Figure 2 In some embodiments of the present invention, the inner peripheral wall of the metal shell 100 is cylindrical, and the plastic support 200 includes a cylindrical portion 230 that mates with the inner peripheral wall of the metal shell 100. A first notch 231 is provided on one side of the cylindrical portion 230 and arranged radially therein. A plastic clamping block 300 is movably disposed within the first notch 231. The plastic clamping block 300 can reciprocate along the arrangement direction of the first notch 231, thereby clamping the surface of the metal ball head 400 or allowing the metal ball head 400 to rotate freely relative to the plastic clamping block 300.

[0038] See Figure 1 and Figure 2 In some embodiments of the present invention, the plastic clamping block 300 is provided with a vertical slot 320, and one end of the first locking member 600 extending into the metal housing 100 is provided with an anti-detachment head 610 inserted into the vertical slot 320. The anti-detachment head 610 cooperates with the vertical slot 320 to facilitate the connection between the plastic clamping block 300 and the first locking member 600, and also prevents the plastic clamping block 300 from deflecting relative to the first locking member 600, ensuring that the metal ball head 400 cannot be displaced relative to the metal housing 100.

[0039] See Figure 1 and Figure 2 In some embodiments of the present invention, the mounting platform 500 includes a first connecting seat 510 connected to the upper part of the metal ball head 400. A second connecting seat 520 is rotatably mounted on the first connecting seat 510 about a vertical axis. The second connecting seat 520 has a threaded connecting post 521, and its outer surface has an annular guide groove 522. A ball bearing 530 extending into the annular guide groove 522 is connected to the first connecting seat 510 via an elastic element 540. An adjusting screw 550 abuts against the elastic element 540 on the first connecting seat 510. The second connecting seat 520 is used to hold photographic equipment. This structure allows the photographic equipment to rotate about a certain diameter of the metal ball head 400. It is understood that by tightening or loosening the adjusting screw 550, the force exerted by the elastic element 540 on the ball bearing 530 can be adjusted, thereby adjusting the ease of rotation of the second connecting seat 520 relative to the first connecting seat 510 to suit different usage needs.

[0040] See Figure 4 The present invention also discloses a projection bracket, comprising: a flat panel mounting base 30 and a connecting rod 40, one end of the connecting rod 40 being connected to the flat panel mounting base 30, and the other end of the connecting rod 40 being provided with the aforementioned gimbal.

[0041] The projection bracket using the above-mentioned gimbal is inexpensive, provides a stable and reliable connection to photography equipment, and the tablet mounting base 30 can be placed on a table or the ground, fixed to a side wall, or fixed to the ceiling. This projection bracket has a variety of uses and a wide range of applications.

[0042] 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.

[0043] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
