Abstract
Description
[Technical field]
[0001] The present invention provides a support for an imaging device that can be quickly adjusted in height. [Background technology]
[0002] Prior art, for example, Patent Document 1 discloses a telescopic support leg locking device that includes a fixed support, a first movable support that is slidably mounted on the fixed support and moves telescopically relative to the fixed support, a first locking structure that is provided between the first movable support and the fixed support and can lock or unlock the first movable support to the fixed support, a second movable support that is slidably mounted on the first movable support and moves telescopically relative to the first movable support, a second locking structure that is provided between the second movable support and the first movable support and can lock or unlock the second movable support to the first movable support, and a linking mechanism that is provided between the second locking structure and the first locking structure and can link and lock or unlock the second locking structure and the first locking structure at the same time. This eliminates the need to operate locking mechanisms in different positions, making it convenient for the user to operate the telescopic support leg locking device and improving convenience of use.
[0003] As described above, in the conventional technology, the fixed support, the first movable support, and the second movable support are arranged in parallel, which increases the lateral size of the entire product and makes it inconvenient to carry and store.
[0004] In the prior art, when locked, the clamp, the first shaft member, and the connecting rod are misaligned as a whole, causing the first locking member to abut against the side wall of the fixed support, thereby fixing the first movable support to the fixed support. The push block acts on the first driving block to move the linkage rod upward, causing the second driving block at the lower end of the linkage rod to act on the second locking member and abut against the side wall of the first movable support. In this locking structure, both the second movable support and the first movable support are fixed by pressing them against the side wall of the support using the locking member, and this locking method using one-sided pressing is prone to scratching the surface of the support, and uneven force is likely to cause problems such as loosening or dents in the support.

A transmission assembly 30 is attached to the first lock receiving seat 120 to drive the lock assembly 20 to unlock or lock, and a drive assembly 50 is further provided on the first lock receiving seat 120 or the connecting receiving portion 100 to drive the operation of the transmission assembly 30.
[0012] In view of the above, by inserting the first movable pipe member, which can move forward and backward relative to the fixed pipe member, into the fixed pipe member, a nested assembly structure is used, thereby reducing the width of the product and achieving convenience in carrying and storing. In addition, by providing a lock assembly for fitting the first movable pipe member outside the first mounting cavity and locking it with the first lock receiving seat, and by adopting a nested assembly structure, it is possible to prevent problems such as wear or loosening caused by receiving force on one side.
[0013] If it is necessary to adjust the position of the first movable pipe member 130 relative to the fixed pipe member 110, the transmission assembly 30 can be driven by the drive assembly 50 to unlock the lock assembly 20, and then the first movable pipe member 130 can be pulled to adjust its forward / backward position relative to the fixed pipe member 110.
[0014] 3 to 7, the first mounting cavity 125 has a connecting hole 121, a taper lock hole 122 and a moving groove 123 in that order from the front to the rear, the rear end of the fixed pipe member 110 is fixed to the connecting hole 121, the lock assembly 20 has a movable member 210 arranged in the moving groove 123 so as to be able to move forward and backward, the movable member 210 is provided with a taper lock bush 220 that can clamp and lock the first movable pipe member 130 by fitting the first movable pipe member 130 around it and inserting it into the taper lock hole 122, a plurality of deformation grooves 221 are drilled in the taper lock bush 220, and the transmission assembly 30 is used to move the movable member 210 in the forward and backward directions relative to the moving groove 123.
[0015] The fixed pipe member 110 is screwed into the connecting hole 121 .
[0016] In the locked state, the taper lock bush 220 is fitted into the taper lock hole 122, and the taper lock hole 122 deforms the taper lock bush 220 to clamp the first movable pipe member 130, thereby placing the first movable pipe member 130, the taper lock bush 220 and the first lock receiving seat 120 in a locked state relative to each other.
[0017] When releasing the lock, the transmission assembly 30 can be released by moving the movable member 210 relative to the first lock receiving seat 120 to disengage the taper lock bush 220 from the taper lock hole 122 and separate the taper lock bush 220 from the first movable pipe member 130.
[0018] 4 to 8, the transmission assembly 30 includes a rotating member 310 rotatably arranged in the first mounting cavity 125, a driving helical tooth portion 312 is provided at an end of the rotating member 310 close to the movable member 210, and the movable member 210 is provided with a driven helical tooth portion 212 that meshes with the driving helical tooth portion 312.
