Description

Technical Field

[0001] This utility model belongs to the field of rotating base technology, specifically referring to a rotating base whose angle can be manually rotated and adjusted. Background Technology

[0002] Most of the rotating bases currently available on the market are equipped with synchronous motors for automatic rotation. However, for other applications, automatic rotation is not required in many places, and manual rotation is necessary. This makes them more reliable and economical in terms of cost and reliability.

[0003] To address the above issues, this paper proposes a novel manual arbitrary angle positioning structure, which is more convenient to use. Simply rotate the base or the object connected to the base to rotate it to the desired angle. Moreover, it is low in cost and has a reliable structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is:

[0005] Existing technology uses a base with a synchronous motor to achieve the rotation function, which sometimes leads to waste of resources and increased costs.

[0006] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a rotating base that can be manually rotated and adjusted, including an upper cover, a lower cover and a rotating structure, wherein the upper cover is fitted onto the lower cover and the rotating structure is installed between the upper cover and the lower cover and is rotatably mounted on the upper cover;

[0007] The upper cover extends a circular thin-walled structure from its center toward the lower cover, and the thin-walled structure has a toothed groove array arranged inward around its inner circumference at one end near the lower cover.

[0008] The rotating structure has symmetrically arranged limiting grooves on one side near the lower cover. A locking button is slidably arranged in the limiting groove. The locking button is located between the limiting groove and the toothed groove and is limited by the lower cover and the rotating structure from the upper and lower sides. A spring is provided between the locking button and the limiting groove.

[0009] Furthermore, the end of the latch near the tooth groove is set in a pointed shape.

[0010] Furthermore, the rotating structure includes a left rotating body and a right rotating body, which are fitted together and form a circular structure lying inside the thin-walled structure of the upper cover. The limiting grooves are respectively opened on the left rotating body and the right rotating body.

[0011] Furthermore, parallel positioning rings are respectively provided on the left and right rotating bodies, and side ribs are arranged in a circumferential array on the inner wall of the circular thin-walled structure on the upper cover, with the side ribs located between the parallel positioning rings.

[0012] Furthermore, the lower cover is provided with limiting and fixing ears distributed circumferentially with respect to the circular thin-walled structure, and the side wall of the upper cover is provided with a locking protrusion. The position of the locking protrusion corresponds to the limiting and fixing ears, and the locking protrusion is locked in the limiting and fixing ears.

[0013] Furthermore, the tooth groove is also provided with protrusions.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] By setting up latches and springs on the rotating structure to work with toothed grooves, rotation and limit can be achieved, allowing manual rotation of the rotating structure and reducing the resource waste caused by setting up a motor. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, the present invention proposes a rotating base that can be manually rotated and adjusted, including an upper cover 1, a lower cover 2 and a rotating structure 3. The upper cover 1 is fixed on the lower cover 2, and the rotating structure 3 is installed between the upper cover 1 and the lower cover 2 and is rotatably mounted on the upper cover 1.

[0025] A circular thin-walled structure extends from the center of the upper cover 1 toward the lower cover 2, and the end of the thin-walled structure near the lower cover 2 is provided with toothed grooves 4 arranged in an inward circumferential array.

[0026] like Figure 4 As shown, a limiting groove 5 is symmetrically opened on the side of the rotating structure 3 near the lower cover 2. A locking button 6 is slidably arranged in the limiting groove 5. The locking button 6 is located between the limiting groove 5 and the toothed groove 4 and is limited from the upper and lower sides by the lower cover 2 and the rotating structure 3. A spring 7 is provided between the locking button 6 and the limiting groove 5.

[0027] During use, when the rotating structure 3 is rotated, the latch 6, which is located in the limiting groove 5, is also driven to rotate. Under the action of the spring 7, the latch 6 is always tightly attached to the tooth groove 4, so it is limited when it rotates to the concave part. When the manual valve drives the rotating structure 3 to rotate, the latch 6 moves to the convex part and squeezes the spring 7 to slide to the next concave part to achieve rotation and fix the position.

[0028] The end of the latch 6 near the tooth groove 4 is set in a pointed shape.

[0029] like Figure 1-4 As shown, the rotating structure 3 includes a left rotating body 8 and a right rotating body 9. The left rotating body 8 and the right rotating body 9 are fitted together and form a circular structure lying in the thin-walled structure of the upper cover 1. The limiting grooves 5 are respectively opened on the left rotating body 8 and the right rotating body 9.

[0030] To prevent the rotating structure 3 from falling off the top cover 1, parallel positioning rings 10 are provided on the left rotating body 8 and the right rotating body 9 respectively. Side ribs 11 are arranged in a circular array on the inner wall of the circular thin-walled structure on the top cover 1, and the side ribs 11 are located between the parallel positioning rings 10.

[0031] To facilitate the installation of the upper cover 1 and the lower cover 2, the lower cover 2 is provided with limiting and fixing ears 12 distributed around the circumference of the circular thin-walled structure, and the side wall of the upper cover 1 is provided with a locking protrusion 13. The position of the locking protrusion 13 corresponds to the limiting and fixing ears 12, and the locking protrusion 13 is locked in the limiting and fixing ears 12.

[0032] like Figure 5 As shown, the tooth groove 4 is also provided with a protrusion 14.

[0033] When using this device, the toothed groove 4 on the upper cover 1 drives the latch 6 and spring 7 for positioning. When rotating, the spring 7 will contract under the action of torque. The latch 6 and spring 7 are integrated as a positioning point and limit. The upper cover 1, lower cover 2 and rotating structure 3 are moving points. Regardless of whether they rotate forward or backward, the rotation function will be realized. The upper and lower limits are achieved by using the protrusion 14 on the upper cover 1, the side rib 11 and the rotating structure 3. The points and surfaces are used to cooperate to fully ensure the gap between the rotating structure 3 and the upper cover 1 and lower cover 2.
