[0003] In the existing technology, when adjusting the shooting height of the camera tube, it is necessary to pull the various tube groups of the camera tube to complete the height adjustment, and connect the various tube groups through locking parts to prevent them from shrinking under the action of their own gravity. However, this operation is very troublesome, and the screws must be loosened each time to adjust the position of the tube group. Therefore, we improve the locking structure between the tubes and propose a new locking technology solution. [Utility Model Content]

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions.

[0024] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," and "connect" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection; direct connection, connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] The following description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to further describe the specific embodiments of the present invention so that the technical solutions and beneficial effects of the present invention are more clearly understood. The following description of the embodiments with reference to the accompanying drawings is for illustrative purposes only and is intended to explain the present invention, but is not to be construed as limiting the present invention.

[0026] The preferred embodiment provided by the present invention is as follows: Figures 1 to 5 As shown, a tube body linkage locking structure of a camera tube, which includes a pin 1, a tube 2, and a first connecting seat 3; the pin 1 is connected to the tube 2 through the first connecting seat 3;

[0027] The first connecting seat 3 includes a pipe seat 4, a connector 5, a locking sleeve 6, and a sleeve 7. The locking sleeve 6, sleeve 7, and connecting member 5 are installed in the pipe seat 4 so that the first connecting seat 3 as a whole slides along the pipe pin 1.

[0028] The connector 5 includes a main portion 51 and a secondary portion 52. The secondary portion 52 extends to both sides of the main portion 51. The main portion 51 is provided with a first connection hole 53, and the secondary portion 52 is provided with a second connection hole 54. The locking sleeve 6 and the sleeve 7 are connected to the pin 1, and the locking sleeve 6 is inserted into the first connection hole 53. The locking sleeve 6 moves with the connector 5 so that the locking sleeve 6 is embedded in the sleeve 7. The locking sleeve 6, sleeve 7 and pin 1 cooperate to prevent the first connector 3 from sliding relative to the pin 1.

[0029] The bottom end of the tube row seat 4 is provided with a cavity 41, in which the connector 5 is placed. The bottom of the cavity 41 is open, and the connector 5 is placed into the cavity 41 from the open bottom. The cavity 41 is provided with a bottom cover 42, which has corresponding holes for the pins 1 to pass through. The bottom cover 42 is locked to the bottom end of the tube row 2 to close the cavity 41. The tube row seat 4 is provided with a first through hole 43 and a second through hole 44. The pin 1 is connected to the first through hole 43, and the tube body of the tube row 2 is connected to the second through hole 44. The tube row seat 4 is provided with a cylindrical cavity 45. The diameter of the cylindrical cavity 45 is larger than the diameter of the first through hole 43. The sleeve 7 is placed in the cylindrical cavity 45 to limit the position of the sleeve 7 in the tube row seat 4 through the cylindrical cavity 45.

[0030] The locking sleeve 6 has a plurality of blocks 61 arranged in a circular pattern with gaps between the blocks 61 to provide elasticity. The locking sleeve 6 is provided with a concave annular groove 62 to secure the locking sleeve 6 to the connector 5, allowing the locking sleeve 6 to move together with the connector 5. The blocks 61 of the locking sleeve 6 are inclined. The sleeve 7 has an access cavity 71 that extends through the sleeve 7. The diameter of the access cavity 71 gradually decreases from its front end to the rear end. The locking sleeve 6 enters the through cavity 81 from the rear end of the sleeve 7. As the sleeve 7 gradually enters the through cavity 81, the blocks 61 gradually close together by abutting against the walls of the access cavity 71. The blocks 61 then press-fit against the pin 1, thereby restricting further relative movement between the first connector 3 and the pin 1.

[0031] The tube row 2 includes a first tube row 21 and a second tube row 22, which are connected by a second connecting seat 8. The second connecting seat 8 has a through cavity 81 that extends through the second connecting seat 8. The first tube row 22 passes through the through cavity 81 and connects to the auxiliary tube portion 52. Counterbores 82 are provided on both sides of the through cavity 81, and the tube bodies of the first tube row 21 are connected to these counterbores 82. The tube body of the first row of tubes 22 is a hollow structure. A sleeve 221 is connected to the tube body of the first row of tubes 22. A third through hole 46 is provided at the second through hole 44. The second through hole 44 and the third through hole 46 are located on the same straight line to facilitate the connection of the tube body. The diameter of the third through hole 46 is smaller than the diameter of the second through hole 44. The diameter of the second row of tubes corresponds to the diameter of the second through hole, and the diameter of the sleeve corresponds to the diameter of the third through hole. The sleeve 221 passes through the third through hole 46 and is connected to the connecting piece 5. The screw passes through the second connecting hole 54 and is connected to the sleeve 221, thereby connecting to the first row of tubes 22 through the sleeve 221.

[0032] Adjustment process: the first row of tubes 21 and the first row of tubes 22 are connected together through the second connecting seat 8, and the first row of tubes 22 passes through the through cavity 81 of the second connecting seat. The first row of tubes 21 and the first row of tubes 22 can move relative to each other to adjust the length. The sleeve 221 in the first row of tubes 22 passes through the third through hole 46 and is fastened to the connecting piece 5, and the tube body of the first row of tubes 22 and the sleeve 221 can move relative to each other; the pin 1 is connected to the first connecting hole 53, and the sleeve 7 and the locking sleeve 6 are connected to the pin 1. In the normal state, the block 61 of the locking sleeve 6 does not enter the through cavity 81 of the sleeve 7, and the first connecting seat 3 can slide along the pin 1, thereby adjusting the relative position of the first row of tubes 22 and the pin 1 to achieve the telescopic function; after the position is adjusted, the sleeve 221 is pulled to make the sleeve 221 and the tube body of the first row of tubes 22 move relative to each other, and the sleeve 221 drives the linkage to move in the concave cavity 41, so that the block 61 of the sleeve 221 is embedded in the through cavity 81 of the sleeve 7, and the block 61, the wall of the through cavity 81, and the pin 1 squeeze each other to limit the relative movement of the pin 1 and the first connecting seat 3, thereby limiting the extension length of the first row of tubes 22 and the pin 1.
