Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission and control, and in particular to a rotary damping dial. Background Technology

[0002] A damping dial is a dial device with damping characteristics, typically consisting of a dial body and a damping mechanism. It is widely used in equipment and mechanisms requiring precise control and stable operation, such as lens adjustments in photographic equipment, air conditioning vents in automobiles, fishing gear, and gimbals.

[0003] The existing damping dials typically have fixed settings for the resistance of the dial and the damping mechanism. This means that damping dials of the same specifications can only be used in a single scenario. If the weight of the object to be connected changes, the effect will be poor. In particular, when the weight increases, the damping dial may not be able to be fixed at a specific angle, which has certain limitations. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rotary damping dial to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a rotary damping dial, including an outer wheel, an inner wheel, and a damping mechanism, wherein at least one damping mechanism is provided between the outer wheel and the inner wheel, wherein the damping mechanism includes a set screw that is threadedly installed on the outer wheel, and also includes a spring and a damping pin provided at the tail end of the set screw, wherein the resistance of the damping pin to the inner wheel is adjusted by tightening or loosening the set screw to compress or release the spring.

[0006] Preferably, the outer wheel has an annular structure, with a circular hole at its center for mounting the inner wheel, and a through threaded hole radially opened on the outer surface of the outer wheel for mounting the set screw of the damping mechanism.

[0007] Preferably, the outer surface inside the inner wheel is provided with an annular groove, and a ring of equidistant spherical grooves are provided on the annular groove.

[0008] Preferably, the tail of the damping pin is provided with an arc-shaped surface, which is adapted to the concave size of the spherical groove.

[0009] Preferably, there are three threaded holes, and a damping mechanism is installed in each threaded hole, with the three damping mechanisms evenly forming a triangular shape on the outer wheel.

[0010] Preferably, a polygonal hole is also provided at the center of the inner wheel for assembly with the object to be connected via a polygonal shaft.

[0011] Preferably, the outer edge of the outer wheel is provided with multiple mounting holes for mounting the damping pulley.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The damping mechanism of this utility model consists of a set screw, a spring, and a damping pin. In use, the spring is compressed or released by tightening the set screw, thereby changing the spring force and adjusting the resistance of the damping pin on the inner wheel. The resistance between the damping pin and the inner wheel can be adjusted according to the usage scenario, so that the damping wheel of the same specification can be used in different scenarios, thereby improving the flexibility and practicality of the damping wheel.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] This utility model provides a rotary damping dial, such as Figure 1 As shown, a rotating damping dial includes an outer wheel 1, an inner wheel 2, and a damping mechanism 3, with the damping mechanism 3 disposed between the outer wheel 1 and the inner wheel 2.

[0023] Specifically, such as Figure 2-3 As shown, the outer wheel 1 has a ring structure, and the circular hole 11 at its center is used to install the inner wheel 2. The outer surface of the outer wheel 1 has a through threaded hole 12 for installing the set screw 31 of the damping mechanism 3.

[0024] Specifically, such as Figure 4-5 As shown, an annular groove 21 is provided on the outer surface of the inner wheel 2, and a ring of equidistant spherical grooves 22 are provided on the annular groove 21.

[0025] Specifically, such as Figure 6 As shown, the damping mechanism 3 includes a set screw 31 that is threaded onto the outer wheel 1, and also includes a spring 32 and a damping pin 33 disposed at the tail end of the set screw 31. The spring 32 and the damping pin 33 are sequentially connected to the tail end of the set screw 31. The tail end of the damping pin 33 is provided with an arc-shaped surface, which is adapted to the concave size of the spherical groove 22.

[0026] In use, by tightening the set screw 31 towards the inner wheel 2, the damping pin 33 remains in contact with the inner wheel 2, thus compressing the spring 32 and increasing its elasticity, thereby increasing the resistance of the damping pin 33 to the inner wheel 2. Conversely, by tightening the set screw 31 in the opposite direction, the spring 32 is released, reducing its elasticity and thus decreasing the resistance of the damping pin 33 to the inner wheel 2. The resistance between the damping pin 33 and the inner wheel 2 can be adjusted according to the usage scenario, allowing the same specification damping dial to be used in different situations, thereby improving the flexibility and practicality of the damping dial.

[0027] Furthermore, a polygonal hole 23 is provided at the center of the inner wheel 2 for assembling with the object to be connected via a matching polygonal shaft, so that the object to be connected can rotate using the inner wheel 2. For example, the object to be connected can be an air conditioner impeller assembly, used to adjust the direction of the air outlet.

[0028] Preferably, the polygonal hole 23 is a square hole in the shape of a quadrilateral, so the inner wheel 2 is assembled with the object to be connected through a square shaft. Alternatively, depending on the usage scenario, it can be a triangular, pentagonal, or hexagonal hole, and the polygonal shaft used can be adapted accordingly.

[0029] Furthermore, multiple mounting holes are provided on the outer edge of the outer wheel 1 for mounting the damping puller. The outer wheel 1 can be fixedly mounted on the object to be used using fasteners such as bolts and screws, so that the outer wheel 1 remains stationary when the inner wheel 2 rotates.

[0030] In this embodiment, there are three threaded holes 12, and a damping mechanism 3 is installed in each threaded hole 12. The three damping mechanisms 3 are evenly triangular on the outer wheel 1. The damping pins 33 of the three damping mechanisms 3 simultaneously abut against the inner wheel 2 to increase the force points on the inner wheel 2, thereby improving the stability of the damping pull wheel in the fixed state and preventing vertical rotation and displacement.

[0031] It can be noted that the number of damping mechanisms 3 can be adjusted according to the size of the damping pulley. If the damping mechanism 3 is used to connect large or heavy objects, the number of damping mechanisms 3 can be increased, and vice versa.

[0032] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0033] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
