Description

Technical Field

[0001] This utility model relates to the field of camera tripod technology, specifically to a support leg tube. Background Technology

[0002] Tripods are typically used to support photographic, video, or surveying equipment. To prevent slippage of the tripod legs while providing support, rubber feet or ground stakes need to be installed at the bottom of the legs, depending on the terrain. When using a hard surface, rubber feet are needed; when using a soft surface such as snow or sand, ground stakes are needed. This means that when changing the location of the tripod, the bottom of the legs needs to be switched between feet and ground stakes. The traditional solution is to remove the feet and then install the ground stakes, or vice versa. The removed feet or ground stakes are usually stored separately, which can easily lead to them being forgotten or lost. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a support tube with a simple structure that can be easily switched between two support modes: floor plug and foot pad, and can avoid the loss of floor plug and foot pad.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A support tube includes a tube, a base, a ground plug, and a foot pad. The upper end of the base is fixedly connected to the lower end of the tube. The base has an axial threaded through hole. One end of the ground plug is flat and the other end is pointed. A portion of the outer circumference of the ground plug has an external thread section. The ground plug can be screwed into the threaded through hole of the base with either end facing upwards through the external thread section. The foot pad is detachably installed at the lower end of the base. The middle of the foot pad has a through hole for the pointed end of the ground plug to pass through.

[0006] In one embodiment, the outer peripheral surface of the ground insert is provided with a first external thread segment and a second external thread segment, and a limiting protrusion is provided between the first external thread segment and the second external thread segment. The outer diameter of the limiting protrusion is larger than the diameter of the threaded through hole of the base. When the ground insert is screwed into the threaded through hole of the base through the first external thread segment, the tip of the ground insert faces downward. When the ground insert is screwed into the threaded through hole of the base through the second external thread segment, the tip of the ground insert faces upward.

[0007] In one embodiment, the foot pad is threaded to the lower end of the base.

[0008] In one embodiment, the outer circumference of the base is provided with a ring of bosses, the outer diameter of which is larger than the outer diameter of the foot tubes; the foot pads are made of flexible material and have stepped through holes that are wider at the top and narrower at the bottom. A groove is provided on the upper wall of the through hole, corresponding to the bosses of the base. The foot pads can deform to allow the bosses of the base to embed into the grooves. To prevent the foot pads from rotating circumferentially relative to the base, the lower end of the base has a rectangular or waist-shaped structure, and a section of the stepped through hole in the foot pads is a rectangular or waist-shaped hole.

[0009] In one embodiment, the foot tube is a carbon fiber tube.

[0010] The beneficial effects of this utility model are as follows: Since the floor plug can be screwed into the threaded through-hole of the base with either end facing upwards, and the foot pad is detachably installed at the lower end of the base, with a through-hole in the middle for the tip of the floor plug to pass through, when switching support modes, the foot pad can be removed first, then the floor plug can be unscrewed from the base and screwed onto the base with one end reversed, and finally the foot pad can be installed on the base. In this way, regardless of whether the support tube is in floor plug support mode or foot pad support mode, both the floor plug and the foot pad are always installed simultaneously on the tube, thus fundamentally preventing the loss or forgetting of the floor plug and foot pad. Furthermore, the support tube provided by this utility model has a simple structure, making it very convenient to process and use, and it is durable. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 7As shown, a support tube includes a tube 10, a base 20, a ground plug 30, and a foot pad 40. The tube 10 is preferably a carbon fiber tube. The upper end of the base 20 is inserted into the lower end of the tube 10 and fixedly connected thereto. The base 20 has an axial threaded through hole 21 in the middle. One end of the ground plug 30 is flat and the other end is a pointed part 34. A portion of the outer circumference of the ground plug 30 is provided with an external thread section. The ground plug 30 can be screwed into the threaded through hole 21 of the base 20 with either end facing upwards. The foot pad 40 is detachably installed at the lower end of the base 20. The middle part of the foot pad 40 is provided with a through hole for the pointed part 34 of the ground plug 30 to pass through.

[0024] Specifically, the outer peripheral surface of the ground plug 30 is provided with a first external thread section 31 and a second external thread section 32. A limiting protrusion 33 is provided between the first external thread section 31 and the second external thread section 32. The outer diameter of the limiting protrusion is larger than the diameter of the threaded through hole 21 of the base 20. When the ground plug 30 is screwed into the threaded through hole 21 of the base 20 through the first external thread section 31, the tip 34 of the ground plug 30 faces downward. When the ground plug 30 is screwed into the threaded through hole 21 of the base 20 through the second external thread section 32, the tip 34 of the ground plug 30 faces upward.

[0025] To enable the foot pad 40 to be detachably installed at the lower end of the base 20, a very common method is to connect the foot pad 40 to the lower end of the base 20 via threads. The structure and principle of this method need not be elaborated.

[0026] To achieve rapid installation and removal between the foot pad 40 and the base 20, this embodiment employs the following technical solution: A raised platform 22 is provided on the outer circumference of the base 20, the outer diameter of which is larger than the outer diameter of the foot tube 10. The foot pad 40 is made of rubber and has a stepped through-hole that is wider at the top and narrower at the bottom. A groove 41 is provided on the upper wall of the through-hole, corresponding to the raised platform 22 of the base 20. The foot pad 40 can deform to allow the raised platform 22 of the base 20 to embed into the groove 41, and can also deform to quickly detach the foot pad 40 from the base 20. To prevent the foot pad 40 from rotating circumferentially relative to the base 20, the lower end of the base 20 is a rectangular or waist-shaped structure 23, and a section of the stepped through-hole of the foot pad 40 is a rectangular or waist-shaped hole 42.

[0027] Because the ground plug 30 can be screwed into the threaded through hole 21 of the base 20 with either end facing upwards through its external thread section, and the foot pad 40 is detachably installed at the lower end of the base 20, with a through hole in the middle of the foot pad 40 for the tip 34 of the ground plug 30 to pass through, when it is necessary to change the support mode, the foot pad 40 can be removed first, then the ground plug 30 can be unscrewed from the base 20 and screwed onto the base 20 with one end turned upside down, and finally the foot pad 40 can be installed on the base 20. In this way, regardless of whether the support tube is in ground plug support mode or foot pad support mode, the ground plug 30 and the foot pad 40 are always installed on the support tube 10 simultaneously, thereby fundamentally preventing the loss or forgetting of the ground plug 30 and the foot pad 40. In addition, the support tube provided in this embodiment is very convenient to process and use due to its simple structure, and it is durable.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the scope of this utility model patent.

[0029] To facilitate understanding by those skilled in the art of the improvements of this utility model over the prior art, some of the drawings and descriptions of this utility model have been simplified, and for clarity, some other elements have been omitted from this application. Those skilled in the art should realize that these omitted elements may also constitute the content of this utility model.
