Description

[Technical Field]

[0001] This utility model mainly relates to a camera pan-tilt body locking structure. [Background Technology]

[0002] Most gimbal locking mechanisms on the market rely on friction between the screw's front end and the retaining ring on the base. This structure has a small contact area, which can easily lead to unstable locking force. Therefore, we have improved the gimbal locking structure and proposed a new technical solution. [Utility Model Content]

[0003] To solve at least one of the above problems, this utility model proposes a new structural solution. The camera gimbal locking structure adopts the following technical solution:

[0004] A camera pan-tilt head main body locking structure includes a pan-tilt head main body, a main body locking ring, a chassis fixing ring, and a locking screw;

[0005] The main body of the gimbal has a cavity, and the main body locking ring and the chassis fixing ring are assembled into the cavity; the main body locking ring has a circular cavity, and the chassis fixing ring is placed in the circular cavity; the main body of the gimbal has a connecting hole, the main body locking ring has a screw hole, and the locking screw passes through the connecting hole and is connected to the screw hole.

[0006] The locking screw passes through the connecting screw hole to drive the main locking ring to move within the cavity, so that the main locking ring presses against the chassis fixing ring to restrict the rotation of the gimbal body relative to the chassis fixing ring.

[0007] Preferably, protrusions extend from both sides of the main locking ring, and locking positions extend from the cavity. The main locking ring is inserted into the cavity so that the protrusions are embedded in the locking positions, so that the gimbal body and the main locking ring rotate synchronously.

[0008] Preferably, the chassis fixing ring has a concave annular groove, and the locking screw passes through the screw hole and moves to abut against the annular groove.

[0009] Preferably, the chassis retaining ring has a protruding screw portion, and the chassis retaining ring is provided with a base. The base has a protrusion, and the screw portion is screwed onto the protrusion to fix the chassis retaining ring to the base.

[0010] Preferably, the base is fitted with a damping ring base, which rotates around the protruding post as an axis.

[0011] Preferably, the base is fitted with a gear adjustment ring, the gear adjustment ring has a through cavity, and the damping ring base is placed inside the through cavity.

[0012] Preferably, a tapered protrusion is engaged at the end of the locking screw.

[0013] The beneficial effects of this utility model compared with the prior art are:

[0014] This improved structure uses a main locking ring to grip the chassis fixing ring, similar to a brake pad. When the screw is tightened forward, the locking ring moves and grips the chassis fixing ring, generating greater friction between the rings. Simultaneously, the front end of the screw also rubs against the fixing ring, resulting in a bidirectional grip that increases the locking force and stability of the gimbal body. It boasts advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] The preferred embodiment provided by this utility model is as follows: Figures 1-4As shown, a camera pan-tilt body 1 locking structure includes a pan-tilt body 1, a body locking ring 2, a chassis fixing ring 3, and a locking screw 4; the end of the locking screw 4 is screwed with a conical protrusion 8 to facilitate the rotation of the locking screw 4.

[0023] The gimbal body 1 has a cavity 11, into which the main locking ring 2 and the chassis fixing ring 3 are assembled; the main locking ring 2 has a circular cavity 21, through which the main locking ring 2 passes, and the chassis fixing ring 3 is placed in the circular cavity 21; the gimbal body 1 has a connecting hole 12, and the main locking ring 2 has a screw hole 22, through which the locking screw 4 passes and is connected to the screw hole 22; protrusions 23 extend from both sides of the main locking ring 2, and locking positions 13 extend from the cavity 11. The main locking ring 2 is inserted into the cavity 11 so that the protrusions 23 are embedded in the locking positions 13, so that the gimbal body 1 and the main locking ring 2 rotate synchronously.

[0024] The locking screw 4 passes through the connecting hole 12 and connects to the screw hole 22, so as to drive the main locking ring 2 to move within the cavity 11, so that the main locking ring 2 presses against the chassis fixing ring 3, thereby restricting the rotation of the gimbal body 1 relative to the chassis fixing ring 3. The chassis fixing ring 3 is provided with a concave annular groove 31, and the locking screw 4 passes through the screw hole 22 and moves to abut against the annular groove 31.

[0025] The chassis fixing ring 3 has a protruding screw portion 32. The chassis fixing ring 3 is equipped with a base 5. The base 5 has a protrusion 51, and the protrusion 51 is provided with an internal thread. The screw portion 32 is screwed onto the protrusion 51 to fix the chassis fixing ring 3 to the base 5. A damping ring base 6 is sleeved on the base 5. The damping ring base 6 rotates around the protrusion 51 as an axis. The damping ring base 6 has a through hole 61, and the protrusion 51 passes through the through hole 61. A gear adjustment ring 7 is sleeved on the base 5. The gear adjustment ring 7 has a through cavity 71, and the damping ring base 6 is placed in the through cavity 71.

[0026] Working principle: When the main body needs to be locked, rotate the locking screw 4 so that the locking screw 4 and the screw hole 22 are screwed together to pull the main body locking ring 2 to move. The main body locking ring 2 and the chassis fixing ring 3 are pressed together to hold the fixing ring. At the same time, the front end face of the screw rubs against the fixing ring groove 31 to further lock the gimbal main body 1. When the gimbal needs to be rotated, rotate the screw in the opposite direction to release the main body.
