[0029] The utility model will be explained in detail below in combination with each embodiment shown in the drawing, but it should be explained that these embodiments are not the limitation of the utility model, and the equivalent transformation or substitution of function, method or structure made by the ordinary skilled in the art according to these embodiments all belong to the protection scope of the utility model.

[0030] Referring to the drawing Figures 1-8 The support frame for photography in the embodiment includes a head 100 and at least one support leg 200 assembled on the head 100, the support leg 200 includes a plurality of telescopic tubes 300, each adjacent two telescopic tubes 300 form a telescopic rod 210 including an inner tube 211 and an outer tube 212, in order to complete the locking and unlocking of the inner tube 211 and the outer tube 212 in each telescopic rod, the locking mechanism 400 is further included between the inner tube 211 and the outer tube 212 and arranged in the inner tube 211 and the outer tube 212, the support leg 200 is stretched to any position, so that the locking mechanism 400 tends to be in the locked state between the inner tube 211 and the outer tube 212 after stretching; in the embodiment, the entire locking mechanism 400 is arranged between the inner tube 211 and the outer tube 212, the locking mechanism cannot be seen on the appearance, the product is more beautiful, without increasing the external joint, and the operation is easy to operate, and the stretching is random, the unlimited locking when stretching to any position is realized, that is, in the embodiment, the support leg realizes the unlimited locking state by the locking mechanism when being stretched to any position, at this time, there is no stretching length requirement, and the application range is more extensive.

[0031] In the embodiment, for unlocking, compared with the compact space near the head 100 when being arranged near the head 100, the unlocking key is arranged at the bottom, that is, the inner tube at the end of the support leg 200 away from the head 100 is provided with the unlocking key 500, in use, the unlocking key 500 is rotated, the inner tube 211 is synchronously driven to rotate, the support leg 200 in the stretched state is retracted, and the unlocking is completed.

[0032] Different from the section by section unlocking mode, in the embodiment, one key unlocking is completed through the unlocking key 500, that is, through rotating the unlocking key, no matter how many groups of telescopic rods can be unlocked, and the contraction is completed.

[0033] In the embodiment, the inner and outer tubes in each group of telescopic rods 210 can also be individually locked without limit, that is, the inner and outer tubes in the telescopic rod are stretched to any position, and the corresponding telescopic rod can be automatically locked.

[0034] In the embodiment, fine adjustment can also be realized for the entire telescopic tube or each group of telescopic rods, at this time, the inner and outer tubes in a group are made close to each other and the distance between them is shortened by rotating the inner tube or the unlocking key, so that fine adjustment is realized. For example, when the working surface is uneven, the lengths of the multiple telescopic tubes must be different, at this time, fine adjustment is made to one telescopic tube to make it adapt to the uneven working surface.

[0035] In the embodiment, the assembly of the unlocking key and the supporting leg is introduced as follows.

[0036] The locking mechanism 400 in the embodiment can slide locally in the supporting leg, specifically, one of the outer tube 212 and the locking mechanism 400 is provided with a sliding groove along the axial direction of the outer tube 212, and the other is provided with a sliding mechanism moving along the sliding groove. At this time, the sliding groove can be arranged on the inner wall of the outer tube 212 or the locking mechanism 400, and the sliding mechanism can be arranged on the inner wall of the outer tube or the outer wall of the locking mechanism. At this time, only relative sliding needs to be completed, and then during stretching, the locking mechanism 400 can drive the inner tube to slide up and down on the inner wall of the outer tube 212.

[0037] Specifically, the locking mechanism 400 includes a fixed mechanism 410 fixed to the inner tube 211 and a sliding mechanism 420 screwing with the fixed mechanism 410. In the embodiment, the sliding mechanism 420 drives the inner tube 211 to slide in the outer tube.

[0038] In the embodiment, in order to realize integrated linkage, the unlocking key 500 is directly fixed to the inner tube 211 of the last telescopic tube, so that it is fixedly connected with the inner tube away from the gimbal 100. Then when the unlocking key 500 is rotated, the inner tube 212 and the fixed mechanism 410 are rotated, and then the sliding mechanism 420 slides up and down with the fixed mechanism 410, controls the distance between the inner and outer tubes, and makes them close or away from each other.

[0039] In this embodiment, the adjacent groups of telescopic rods 210 share a tube, such as the inner tube of the previous section constituting the outer tube of the next section, and during rotation, linkage between multiple telescopic rods 210 is inevitable. At this time, when the unlocking key 500 rotates, the inner tube 211 of the support leg 300 away from the gimbal 100 rotates, synchronously driving the inner tube 211 of the telescopic rod 210 in the extended state to rotate and unlock.

[0040] Specifically, the unlocking key 500 in this embodiment includes a sleeve 510, which is sleeved and fixed to the outer tube 211 of the telescopic tube 300 away from the gimbal. In this embodiment, by being arranged externally, it is convenient for users to directly operate, and by being assembled in the form of a sleeve 510, it is convenient for assembly.

[0041] In this embodiment, in order to ensure the support of the support leg, a support mechanism 600 extending into the inner tube 212 of the support leg 200 away from the gimbal 100 is further included, and the support mechanism 600 forms a support surface at the bottom of the telescopic tube 300. In this embodiment, the support mechanism 600 can be arranged next to the unlocking key 500, and the support mechanism 600 is partially inserted into the inner tube in the form of a double-layer slot to form a footing support.

[0042] The locking principle and structure between the inner and outer tubes are described in detail as follows:

[0043] First, for a specific telescopic rod 210, the locking mechanism 400 includes an expansion mechanism 430 between the inner tube 211 and the outer tube 212, and the expansion mechanism 430 expands against the outer tube 212, so that the inner tube 211 and the outer tube 212 tend to be in an interference locking state. During this process, the expansion mechanism 430 will be in an outward expansion or inward depression state. When it expands outward, it will press the outer tube 212, so that the inner tube 211 and the outer tube 212 are interfered and locked by external force, and when it is depressed inward, it moves away from the outer tube 212, so that there is a gap between the inner and outer tubes, and relative movement can be achieved to complete unlocking.

[0044] In the above process, the expansion mechanism can also be interfered by a driving mechanism to expand or contract. Specifically, the driving mechanism can be a slope in the expansion mechanism 430 and / or the outer tube 212, and the two slopes are parallel to each other. When they approach each other, the interference force between the two slopes increases, causing the expansion mechanism to expand and lock, and when they move away from each other, the interference force between the two slopes decreases, causing the expansion mechanism to contract and unlock.

[0045] Of course, in the embodiment, the fixing mechanism 410 can be provided with a hollow column near the sliding mechanism 420, and then a plurality of assembly spaces are provided outside the sliding mechanism 420, the expansion mechanism 430 includes a plurality of arc-shaped pieces, and then a plurality of convex inclined surfaces are provided outside the hollow column, and then in rotation, the convex inclined surfaces make the expansion mechanism 430 expand outward eccentrically, and the expansion is completed, and reverse rotation is realized.

[0046] Specifically, in the embodiment, the diameters of the telescopic pipes gradually decrease from the outer side of the holder 100, the telescopic pipes with large diameters constitute the outer pipe 212, and the telescopic pipes with small diameters constitute the inner pipe 211.

[0047] The support frame in the embodiment can be composed of three support legs to form a tripod, or can be composed of more support legs to form various modes, but for each support leg 200, the scheme in the embodiment can realize the effect of stretching locking and rotating one step unlocking, and can also finely adjust the rotation for uneven working surfaces without increasing external joints, thereby ensuring the aesthetics.

Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
