[0026] The locking structure of the schematic tripod socket is described with reference to Figures 2 to 5, a locking structure of a tripod holder according to a preferred embodiment of the utility model, be equipped with on tripod, the tripod includes a holder 10 and a holder 20, the holder 20 has a sliding slot 201, the holder 10 is slidably arranged on the sliding slot 201 of the holder 20.

[0027] Further, to realize the holder 10 is slidably arranged on the holder 20, as shown in Figure 3 And Figure 4 The bottom of the holder 10 has a rack part 101, the holder 20 also has a through cavity 202, the through cavity 202 is communicated with the sliding slot 201, one end of the holder 10 with the rack part 101 is slidably arranged on the sliding slot 201, in addition, the locking structure of the tripod holder includes a gear shaft 30, the gear shaft 30 is rotatably installed on the holder 20 through bearing, and the gear on the gear shaft 30 is placed in the through cavity 202 and is engaged with the rack part 101.

[0028] It needs to be explained that when the front and back positions of the rod-shaped piece need to be adjusted, only the gear shaft 30 is rotated, then the gear on the gear shaft 30 drives the rack part 101 to move, and the holder 10 is moved along the sliding slot 201, and the rod-shaped piece held by the holder 10 is moved along the front and back.

[0029] Further, to realize that when the gear shaft 30 is rotated after the holder 10 is moved to the specified position of the sliding slot 201, the holder 10 will not be moved again, realize the "locking" of the position of the holder 10, in the embodiment of the application, as shown in Figure 5 The locking structure of the tripod holder further includes a sliding sleeve 40, one end of the gear shaft 30 has a light axis surface 301 and an embedding surface 302, the embedding surface 302 has a plurality of recesses (not marked in the figure) arranged in annular array, the embedding surface 302 is located at the end of the gear shaft 30, the sliding sleeve 40 has a hole 401, the hole 401 has a plurality of convexities 4011 arranged in annular array near the end hole wall of the holder 20, the convexities 4011 correspond to the recesses one by one, the convexities 4011 extend into the recesses or the convexities 4011 are located outside the light axis surface 301 and are spaced apart from the light axis surface 301 by a predetermined distance in the radial direction of the gear shaft 30.

[0030] It should be noted that when the protrusion 4011 is located outside the optical axis surface 301, the rotation of the sliding sleeve 40 does not drive the gear shaft 30 to rotate because the protrusion 4011 on the sliding sleeve 40 is spaced apart from the optical axis surface 301 by a predetermined distance; when the protrusion 4011 extends into the groove, the protrusion 4011 and the groove cooperate, and at this time, rotating the sliding sleeve 40 drives the gear shaft 30 to rotate; in view of this, when it is necessary to move the holder 10, the user moves the sliding sleeve 40 away from the holder 10 and makes the protrusion 4011 extend into the corresponding groove, at this time, rotating the sliding sleeve 40 drives the gear shaft 30 to rotate and moves the holder 10 to a specified position of the sliding groove 201; after the holder 10 is moved to the specified position of the sliding groove 201, the sliding sleeve 40 is moved towards the holder 10 and the protrusion 4011 is located outside the optical axis surface 301, at this time, even if the sliding sleeve 40 is accidentally touched and rotated during use, the gear shaft 30 will not rotate and drive the holder 10 to move, achieving the locking of the position of the holder 10 and further achieving the advantage that the holder 10 can be selectively moved when the rotating member rotates. In addition, when the protrusion 4011 is not directly opposite the groove, the operator only needs to rotate the sliding sleeve 40 during the process of moving the sliding sleeve 40 away from the holder 10, and the sliding sleeve 40 is directly opposite the groove and extends into the groove after rotating by a predetermined angle.

[0031] Further, to avoid the sliding sleeve 40 from being separated from the gear shaft 30 due to excessive force applied by the operator during the process of moving the sliding sleeve 40 away from the holder 10, Figure 5 As shown, the locking structure of the tripod holder 10 further includes a anti-disengagement piece 50, the maximum radial dimension of the anti-disengagement piece 50 is greater than the minimum radial dimension of the hole 401 having the protrusion 4011, when the protrusion 4011 passes through the groove and is located outside the optical axis surface 301, the anti-disengagement piece 50 is fixedly connected with one end surface of the gear shaft 30 having the embedded surface 302, and the fixed connection mode includes but is not limited to adhesive connection.

[0032] It should be noted that because the maximum radial dimension of the anti-disengagement piece 50 is greater than the minimum radial dimension of the hole 401 having the protrusion 4011, when the protrusion 4011 abuts against the anti-disengagement piece 50, the protrusion 4011 is blocked and cannot be further moved away from the holder 10.

[0033] Further, to achieve the placement of the anti-disengagement piece 50 into the hole 401 and the connection with the end surface of the gear shaft 30, Figure 5As shown, the hole 401 is a through hole, and the locking structure of the tripod holder further comprises a abutting member 60, which is detachably connected with one end of the hole 401 away from the holder 20. In the embodiment of the present application, the abutting member 60 is threadedly connected with the hole 401.

[0034] It should be noted that the abutting member 60 is separated from the hole 401 so as to facilitate the anti-drop sheet 50 to be put into the hole 401 and bonded with the gear shaft 30. After the anti-drop sheet 50 is connected with the gear shaft 30, the abutting member 60 is threadedly connected with the hole 401.

[0035] Further, in order to realize that the protrusion 4011 is located outside the optical axis surface 301, as shown in Figure 5 As shown, the sliding sleeve 40 is provided with a first magnetic member 402 at one end close to the holder 20, and the holder 20 is provided with a second magnetic member 203 at one end close to the sliding sleeve 40. The magnetic properties of the first magnetic member 402 and the second magnetic member 203 are opposite. In the present application, the first magnetic member 402 and the second magnetic member 203 are both implemented as magnetic rings. When the protrusion 4011 is located outside the optical axis surface 301, the first magnetic member 402 and the second magnetic member 203 are close to each other, and under the action of magnetic force, the protrusion 4011 is located outside the optical axis surface 301. In addition, when the protrusion 4011 extends into the groove, since the distance between the first magnetic member 402 and the second magnetic member 203 is far, the magnetic attraction force between the first magnetic member 402 and the second magnetic member 203 can be ignored.

[0036] Further, in order to facilitate the user to rotate the sliding sleeve 40, as shown in Figure 4 The outer wall of one end of the sliding sleeve 40 away from the holder 20 is provided with a knurl 403.

[0037] Further, in order to avoid that the rod-shaped member is separated from the holder 10 on both sides, as shown in Figure 2 The top of the holder 10 is provided with two symmetrically arranged arch corner portions 101, and the rod-shaped member is placed between the two arch corner portions 101.

[0038] In summary, the locking structure of the tripod holder according to the embodiment of the present application is illustrated, which provides the advantage that the rotating member can selectively drive the holder to move when rotating.

[0039] It is worth mentioning that, in the embodiment of the present application, the locking structure of the tripod holder is simple in structure, does not involve complex manufacturing process and expensive materials, and has higher economy. At the same time, for the manufacturers, the locking structure of the tripod holder provided by the present application is easy to produce and low in cost, which is more conducive to controlling the production cost, and is further conducive to the promotion and use of the product.

[0040] It will be understood by those skilled in the art that the embodiments of the present application shown in the above description and the accompanying drawings are only examples and do not limit the present application. The purpose of the present application has been completely and effectively achieved. The function and structural principle of the present application have been shown and described in the embodiments, and the embodiments of the present application can be any deformation or modification without departing from the principle.
