Description

Technical Field

[0001] The utility model relates to the field of photographic equipment, in particular to a telescopic tripod locking structure and a telescopic tripod. Background Art

[0002] A tripod is an instrument used to support and adjust photographic equipment during photographic activities, and existing tripods usually have a multi-stage telescopic structure. In order to achieve one-touch telescopic extension of the tripod, existing tripods all use a lever to drive a clamping block to clamp the telescopic tube, thereby limiting the movement of the telescopic tube. However, this locking method has a long locking time and is prone to loosening after long-term use. In particular, after the lever is worn, the driving force generated by the eccentric part of the lever is weakened, causing the telescopic tube to be accidentally unlocked. Therefore, a new telescopic tripod locking structure and a telescopic tripod are urgently needed to solve the above problems. Utility Model Content

[0030] The first abutting portion 41 and the second abutting portion 42 can move toward or away from each other in the base body 10 under the driving of the driving portion 30 .

[0031] ①Reference Figure 1-2, is a structural schematic diagram of a telescopic tripod, which is described by taking the structure of the telescopic tripod as an example. Specifically, the telescopic tripod includes three stages, the first stage is composed of two first tubes (locked parts 80) that are penetrated through the base body 10 and located on both sides of the first extrusion part 71 and the second extrusion part 72, the second stage is composed of two second tubes that are connected to the base body 10 at one end and extend downward at the other end, the third stage is composed of two third tubes 81 that are inserted into the second tube at one end and can be telescoped relative to the second tube at the other end, and the first tube is connected to the base body 10 through the locking structure provided by the utility model.

[0032] ② In one embodiment, the driving portion 30 is provided with a first tooth portion 51, and the first abutting portion 41 and the second abutting portion 42 are respectively provided with a second tooth portion 52 and a third tooth portion 53 meshing with the first tooth portion 51, so as to drive the first abutting portion 41 and the second abutting portion 42 to rotate;

[0033] In one embodiment, a locking structure of a telescopic tripod further includes a first extruding portion 71 disposed in the base body 10 and located between the first abutting portion 41 and the locked portion 80, and a second extruding portion 72 disposed in the base body 10 and located between the second abutting portion 42 and the locked portion 80; the first extruding portion 71 is connected to the first abutting portion 41 through a first limiting structure to limit the rotation of the first abutting portion 41 in the base body 10; the second extruding portion 72 is connected to the second abutting portion 42 through a second limiting structure to limit the rotation of the second abutting portion 42 in the base body 10;

[0034] Specifically, when the driving portion 30 is in the locked state, the first abutting portion 41 and the second abutting portion 42 will be driven to rotate, and the first abutting portion 41 is connected to one side of the transmission portion 20 through the first threaded connection structure 61, and the second abutting portion 42 is connected to the other side of the transmission portion 20 through the second threaded connection structure 62. The spiral direction of the first threaded connection structure 61 is opposite to the spiral direction of the second threaded connection structure 62, which will cause the first abutting portion 41 and the second abutting portion 42 to move in opposite directions relative to the transmission portion 20, thereby The first extrusion portion 71 connected to the part 41 and the second extrusion portion 72 connected to the second abutment portion 42 respectively squeeze the two first tubes to limit the relative movement between the first tubes and the seat body 10; when the driving portion 30 is in an unlocked state, the first abutment portion 41 and the second abutment portion 42 will move toward each other relative to the transmission portion 20, and the first extrusion portion 71 connected to the first abutment portion 41 and the second extrusion portion 72 connected to the second abutment portion 42 will move away from the two first tubes, so that the first tube can move relative to the seat body 10.

[0035] ③ In one embodiment, the first stage and the third stage of the telescopic tripod are connected by a linkage structure, so that when the first stage is in a locked state, the third stage can be linked to be in a locked state as well, so as to realize one-key locking of the three-stage telescopic structure, or when the first stage is in an unlocked state, the third stage can be linked to be in an unlocked state as well, so as to realize one-key unlocking of the three-stage telescopic structure; specifically, the linkage structure includes a connecting seat 91, a hook 92, a pull rod 93, a first push block 94 and a second push block 95, wherein one end of the hook 92 is respectively connected to the first abutting portion 41 and the second abutting portion 42, the other end of the hook 92 is connected to one end of the pull rod 92, the other end of the pull rod 92 is connected to the first push block 94, the second push block 95 is movably arranged in the connecting seat 91, the two ends of the two third tubes 81 are respectively inserted in the seat body 10 and the connecting seat 91 and are arranged on both sides, the second push block 95 abuts against one of the third tubes 81, and of course, a third push block can also be arranged to abut against another third tube 81;

[0036] Furthermore, the driving part 30 drives the first abutting part 41 and the second abutting part 42 to rotate, and at the same time pulls the pull rod 93 upward or pushes the pull rod 93 downward through the pull hook 92. The first push block 94 cooperates with the second push block 95 through the inclined surface, so that when the pull rod 93 moves upward, the first push block 94 drives the second push block 95 and the third push block to move in opposite directions, thereby squeezing the two third tubes 81 respectively, restricting the third tube 81 from moving relative to the connecting seat 91, and when the pull rod 93 moves downward, the first push block 94 drives the second push block 95 and the third push block to move in opposite directions, thereby releasing the squeezing of the third tube 81, so that the third tube 81 can move relative to the connecting seat 91;

[0037] ④ The advantage of the utility model is that the one-touch locking and unlocking of the locked part is achieved through the above structure, which has the advantages of fast unlocking speed and convenient operation, and meets the use requirements.

[0038] In one embodiment, a limiting groove 11 is disposed in the seat body 10 , and the first abutting portion 41 and the second abutting portion 42 extend into the limiting groove 11 to limit the movement stroke of the first abutting portion 41 and the second abutting portion 42 in the seat body 10 .
