Description

Technical Field

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

[0002] The existing tripod includes a central axis, a base and leg tubes. The central axis passes through the base and is movably connected to the base. The central axis can slide relative to the base. The leg tubes are movably connected to the base. The leg tubes are rotatably connected to the base through a rotating shaft. The leg tubes can be rotated to open or store relative to the base. A storage groove is provided on the central axis. When the leg tubes are stored, the leg tubes are rotated to be accommodated in the storage groove.

[0003] Among them, when the leg is in the unfolded position, the leg is locked to the base by the rotating shaft, that is, it is locked only by the locking screws, so that the friction between the base and the leg is sufficient to support the leg from being retracted in the absence of external force. However, the locking screws may become loose during use, which will cause the leg to be out of the locked state, making the stability of the tripod supporting the object worse. Utility Model Content

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] The utility model provides a tripod, in particular a photographic tripod, but the scope of the invention is not limited thereto.

[0032] Reference Figures 1 to 6In one embodiment of the utility model, the tripod includes a base 10 and a leg tube 20; the base 10 is provided with a stopper 101; the number of the leg tubes 20 is at least three, one end of the leg tube 20 is rotatably arranged at the stopper 101 and a friction portion 201 is provided at a position of the leg tube 20 corresponding to the stopper 101, and when the leg tube 20 is opened, the friction portion 201 is in interference contact with the stopper 101.

[0033] In this embodiment, the stopper 101 can be a mounting groove provided on the base 10, and the corresponding friction part 201 can be a convex part provided on the end of the leg tube 20. Of course, the interference structures on the base 10 and the leg tube 20 can be interchanged, that is, the stopper 101 is a convex block provided on the base 10, and the friction part 201 is a groove provided on the end of the leg tube 20. The following will mainly introduce the stopper 101 as a mounting groove and the friction part 201 as a convex part as an example, but this article is not limited to this. Any structure that can lock the rotating end of the leg tube 20 on the base 10 by interference contact when the leg tube 20 is in a fully open state can be used, and it is not limited here.

[0034] In this embodiment, the leg tube 20 and the base 10 can be rotatably connected via a rotating shaft 22. The rotating shaft 22 can be composed of locking screws, or the rotating shaft 22 can be a round rod or a rivet, etc. This embodiment uses locking screws, which is not limited here.

[0035] The utility model improves the structure of the tripod. When the leg tube 20 is folded, the friction portion 201 of the leg tube 20 and the base 10 are in a natural state. When the leg tube 20 is opened, the friction portion 201 of the leg tube 20 and the stop portion 101 of the base 10 are in an interference state, thereby providing sufficient friction to the leg tube 20. In this way, the leg tube 20 will not be folded without external force, thereby effectively improving the stability of the object supported by the tripod.

[0036] It should be noted that when the leg tubes 20 are folded, the friction portion 201 of the leg tube 20 and the base 10 are in a natural state, which means that when the leg tubes 20 are folded together, there is a gap between the friction portion 201 of each leg tube 20 and the corresponding stop portion 101, or the friction portion 201 lightly rests on the stop portion 101, so that the user can open the leg tube 20 more easily.

[0037] In order to facilitate processing and manufacturing, the main reference Figures 3 to 6 In one embodiment, a connector 21 may be provided at one end of the leg tube 20, and a convex portion is provided at the outer end of the connector 21 to form a friction portion 201. When the leg tube 20 is opened, the convex portion is in interference contact with the groove wall of the installation groove.

[0038] In this embodiment, the outer contour line of the protrusion may be arc-shaped or wavy, or the outer contour of the protrusion may be consistent with the curved contour of the cam mechanism, as long as the structure can satisfy the interference state with the base 10 when the leg tube 20 is opened.

[0039] In this embodiment, the connector 21 includes a connecting body 211 and a rotating arm 212 connected to the connecting body 211. The convex portion is provided on the end of the rotating arm 212. The rotating arm 212 is provided with a rotating shaft hole 213 for inserting the rotating shaft 22 connecting the rotating arm 212 and the base 10. In this way, the convenience of assembly can be further improved while the convex portion can be conveniently processed.

[0040] The connecting body 211 and the leg tube 20 may be fixed by means of clamping, bonding or welding, which are not limited here.

[0041] Of course, in other embodiments, the friction portion 201 may be directly processed at the end of the leg tube 10, which can reduce the number of parts and facilitate subsequent assembly.

[0042] In order to avoid shrinkage of the connector 21, save materials and reduce costs, further, refer to Figures 4 to 6 The connector 21 may be provided with a plurality of glue reducing holes 214 .

[0043] In addition, to improve the stability of supporting cameras and other equipment, refer to Figures 1 to 4 In one embodiment, the tripod may further include a central axis 30 and a support plate 40. The base 10 is sleeved on the central axis 30. When the leg tubes 20 are in the folded state, each leg tube 20 is folded on the central axis 30. The support plate 40 is arranged on the base 10. The support plate 40 is provided with screws 41. The screws 41 are suitable for connecting with the device to be supported. The screws 41 may be 1 / 4 or 3 / 8 standard camera screws, etc., which are not limited here.

[0044] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
