DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides as Figures 1 - 3The displacement assembly shown in the figure includes a displacement support seat 100, and both ends of the displacement support seat 100 are provided with strip-shaped mounting holes 101. There are two strip-shaped mounting holes 101 located on the same side of the displacement support seat 100 and arranged in parallel and at intervals. The opening of the strip-shaped mounting holes 101 facilitates the adjustment of the mounting position of threaded fasteners such as bolts or screws on the displacement support seat 100, making the installation of the displacement support seat 100 on the external frame more flexible. The top of the displacement support seat 100 is provided with a rotatable rotating shaft 200, and the rotating shaft 200 is used for the turntable. The support is fixed, and the turntable body 400 is connected and supported by the rotating shaft 200, and the rotating shaft 200 can rotate and tilt the turntable body 400 to achieve the function of tilting and displacement of the turntable body 400. The side wall of the displacement support seat 100 is provided with a rotating driving mechanism 300, and the rotating driving mechanism 300 is used to drive the rotation of the rotating shaft 200. The rotating shaft 200 is driven to rotate by the rotating driving mechanism 300, so as to achieve the driving of the tilting and displacement of the turntable body 400;

[0022] In a preferred embodiment, the rotary drive mechanism 300 includes a bearing shell 301 fixed to the side wall of the displacement support seat 100 and a worm 303 arranged at the inner bottom of the bearing shell 301 and capable of rotating. A worm wheel 302 is arranged at the inner top of the bearing shell 301. The middle part of the worm wheel 302 is fixedly plugged with the end of the rotating shaft 200. The middle part of the worm 303 is meshedly connected with the bottom of the worm wheel 302. One end of the worm 303 extends to the outside of the bearing shell 301 and is fixedly connected with a crank. The crank is used to drive the worm 303 to rotate clockwise or counterclockwise, so that the worm 303 drives the worm wheel 302 to rotate, thereby driving the rotating shaft 200 clockwise or counterclockwise. By rotating counterclockwise, the tilt angle of the turntable body 400 fixedly connected to the rotating shaft 200 is adjusted. At the same time, due to the self-locking effect between the worm 303 and the worm wheel 302, after rotating the worm 303 to adjust the tilt position of the turntable body 400, when there is no external force acting on the worm 303 to rotate it, the worm 303 keeps its position fixed, and the worm 303 cannot be driven to rotate by the rotation of the worm wheel 302. In this way, it is impossible to apply a force on the turntable body 400 to drive it to rotate, thereby locking the tilt position of the turntable body 400, making the adjustment operation of the tilt and displacement of the turntable body 400 more convenient.

[0023] Furthermore, the crank handle includes a connecting arm 308, and the bottom of the connecting arm 308 away from the worm 303 is fixedly connected to a T-shaped shaft 309, and the outer wall of the T-shaped shaft 309 is movably sleeved with a grip sleeve 310. The outer wall of the T-shaped shaft 309 is sleeved with a rotatable grip sleeve 310, which can increase the convenience and effort of manually holding the grip sleeve 310 to rotate the connecting arm 308, and is more convenient to use. A convex groove 304 is provided at the end of the worm 303 facing the crank handle, and the interior of the convex groove 304 is a polyhedron. A limiting piece is fixedly provided on the top of the connecting arm 308 facing the worm 303, and the outer wall of the limiting piece is movably plugged into the inner cavity of the convex groove 304, and the limiting piece is used to move in the convex groove 304. The convex groove 304 can be moved in the connecting arm 308, so that the connecting arm 308 can be engaged or separated with the convex groove 304 by driving the limiting member to translate, thereby achieving the limit locking or unlocking between the connecting arm 308 and the convex groove 304, so that the connecting arm 308 can drive the worm 303 to rotate, and can also be in an unlocked state with the worm 303 and cannot drive it to rotate; wherein the limiting member includes a connecting rod 307 fixedly connected to the side wall of the connecting arm 308, one end of the connecting rod 307 is fixedly connected to a positioning block 306, and the side of the positioning block 306 facing away from the connecting rod 307 is fixedly connected to a guide slider 305, and the outer wall of the guide slider 305 is connected to the convex groove 304. The inner wall of the slot 304 is movably fitted, the mating part between the convex slot 304 and the guide slider 305 is circular, and the mating part between the inside of the convex slot 304 and the positioning block 306 is polygonal. After the connecting arm 308 is pressed inwardly to drive the cylindrical guide slider 305 to move inwardly so that the positioning block 306 is separated from the corresponding position of the convex slot 304, the lock between the limiter and the convex slot 304 can be released, so that the worm 303 cannot be driven to rotate when the connecting arm 308 rotates, and the connecting arm 308 is pulled outward to move the guide slider 305 outward, driving the positioning block 306 to be inserted into the corresponding position of the port of the convex slot 304 When the handle is in the correct position, the positioning block 306 is inserted and engaged with the corresponding position of the convex groove 304 to achieve the limit between the limit piece and the convex groove 304, so that the connecting arm 308 can be rotated and the worm 303 can be driven to rotate at the same time. Such a design can prevent the crank handle from being accidentally touched. When not adjusting, the connecting arm 308 can be squeezed inward to drive the limit piece and the convex groove 304 on the end face of the worm 303 to form an unlocked state, and the worm 303 cannot be driven to rotate by the connecting arm 308. When adjustment is needed, only the connecting arm 308 needs to be pulled outward to lock the limit piece and the convex groove 304. The operation is simple and convenient, and it also has the effect of preventing accidental collision.

[0024] In another embodiment, the utility model further provides a turntable, including the above-mentioned displacement assembly, and also including a turntable body 400 fixedly connected between two rotating shafts 200, and a connecting seat 401 is fixedly provided on the top of the turntable body 400.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
