Description

Technical Field

[0001] This utility model relates to the field of tripod technology, and specifically to a folding tripod. Background Technology

[0002] Tripods are widely used in photography, surveying, painting, medical equipment and other fields, and folding tripods are becoming increasingly popular due to their portability.

[0003] An existing type of folding tripod has the following structure: Figure 1 As shown, the tripod includes a connecting shaft 1a, a connecting module, a fastening module, and a support module. The connecting module includes a connecting guide sleeve 2a and a support sleeve 3a. The fastening module includes a first hand-tightening bolt 4a and a second hand-tightening bolt 5a. The support module includes three legs 6a and three connecting rods 7a. The connecting shaft 1a is inserted into the connecting guide sleeve 2a, with its bottom abutting against the bottom of the support sleeve 3a. The connecting shaft 1a is fixed inside the connecting guide sleeve 2a by the first hand-tightening bolt 4a and inside the support sleeve 3a by the second hand-tightening bolt 5a. One end of the leg 6a is hinged to the connecting guide sleeve 2a, and one end of the connecting rod 7a is hinged to the middle of the leg 6a, while the other end is hinged to the support sleeve 3a. This folding tripod is relatively stable when unfolded because of the connecting rods 7a between the three legs 6a and the connection of the connecting rods 7a to the connecting shaft 1a via the support sleeve 3a.

[0004] However, existing folding tripods still have the following technical problems: the stable structure consisting of connecting rod 7a, support sleeve 3a, and connecting central axis 1a is relatively complex, and when folded, such as Figure 2 As shown, it is necessary to unscrew the second hand-tightening bolt 5a to separate the support sleeve 3a from the connecting shaft 1a. However, when unfolding, it is necessary to install the support sleeve 3a onto the connecting shaft 1a and tighten the second hand-tightening bolt 5a. Therefore, both folding and unfolding are very inconvenient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a folding tripod with a relatively simple and stable structure, and which is more convenient to fold and unfold.

[0006] The technical solution of this utility model is: a folding tripod, including an end cap and three legs hinged to the end cap at the top. A folding lever is also provided between two adjacent legs. The folding lever folds as the legs are closed and unfolds as the legs are opened. The three unfolded folding levers form a triangular support on the three legs.

[0007] With the above structure, this utility model has the following advantages:

[0008] This utility model of a folding tripod only requires a folding lever between two adjacent legs to form a triangular support when the three legs are opened, thus keeping the three legs stable. The stabilizing structure is relatively simple. The folding and unfolding of the folding lever is automatically completed along with the closing and opening actions of the legs, without the need for additional operation, making folding and unfolding more convenient.

[0009] Preferably, the folding rod includes a first rod and a second rod, with the first end of the first rod and the first end of the second rod respectively hinged to two adjacent support legs, and the second end of the first rod hinged to the second end of the second rod. This configuration makes the folding rod a two-section structure that folds in the middle, making folding more convenient and taking up less space after folding.

[0010] Preferably, a locking structure is provided between the second end of the first rod and the second end of the second rod. The locking structure disengages as the folding rod is folded and engages as the folding rod is unfolded. This locking structure allows the folding rod to maintain its shape when unfolded, thus making the triangular support formed by the folding rod more stable and providing stronger support.

[0011] Preferably, the locking structure includes a slot disposed on one of the second ends of the first rod and the second end of the second rod, and a buckle disposed on the other. When the folding rod is folded, the buckle disengages from the slot; when the folding rod is unfolded, the buckle engages with the slot. This locking structure uses a buckle mechanism, making it easy to engage and disengage.

[0012] Preferably, the top or bottom of the slot is open, and the buckle includes a bevel that gradually extends into the slot. When the folding rod is folded, the bevel disengages from the slot, and when the folding rod is unfolded, the bevel engages with the slot. This buckle structure is simple, and the bevel design makes it easier to connect and separate the buckle from the slot.

[0013] Preferably, the second end of the first rod is disposed within the second end of the second rod, the slot is disposed at the top of the second end of the second rod, and the inclined surface is disposed on the second end of the first rod and gradually extends from the inside to the slot. This arrangement makes the locking structure layout reasonable and the structure compact.

[0014] Preferably, the top of the end cap is closed, and the bottom extends inward to form a receiving cavity for accommodating the upper ends of the three legs. The receiving cavity has three limiting portions, and the upper ends of the three legs are respectively hinged within the three limiting portions of the receiving cavity. This end cap structure not only simplifies the structure by mounting the three legs within the same receiving cavity, but also utilizes the limiting portions within the receiving cavity to allow each leg to move within a defined range without interference.

[0015] Preferably, the two ends of the folding rod are respectively connected to the upper part of two adjacent support legs. This arrangement not only reduces the length of the folding rod, but also allows for a suitable unfolding angle of the support legs, thus making the support legs more stable after unfolding.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Example:

[0028] like Figure 3-8As shown, a folding tripod includes an end cap 1 and three legs 2 hinged to the end cap 1 at their upper ends. A folding lever 3 is also provided between two adjacent legs 2. The folding lever 3 folds as the legs 2 are closed and unfolds as the legs 2 are opened. The unfolded three folding levers 3 form a triangular support on the three legs 2. In this embodiment, the directions of up, down, top, bottom, inside, and outside are... Figure 3 As the standard.

[0029] In this embodiment, the folding tripod only requires a folding lever 3 between two adjacent legs 2 to form a triangular support after the three legs 2 are opened, thus keeping the three legs 2 stable. The stabilizing structure is relatively simple. The folding and unfolding of the folding lever 3 are automatically completed along with the closing and opening actions of the legs 2, without the need for additional operation, so folding and unfolding are more convenient.

[0030] The folding lever 3 includes a first lever 6 and a second lever 7. The first end of the first lever 6 and the first end of the second lever 7 are respectively hinged to two adjacent support legs 2. The second end of the first lever 6 is hinged to the second end of the second lever 7. In this embodiment, both the first lever 6 and the second lever 7 are hinged to the support legs 2 by riveting, and the first lever 6 and the second lever 7 are also hinged together by riveting. This design makes the folding lever 3 a two-section structure that folds in the middle, making folding more convenient and reducing the space occupied after folding.

[0031] A locking structure 8 is also provided between the second end of the first rod 6 and the second end of the second rod 7. The locking structure 8 disengages as the folding rod 3 is folded and engages as the folding rod 3 is unfolded. The locking structure 8 enables the folding rod 3 to maintain its shape when unfolded, thereby making the triangular support formed by the folding rod 3 more stable and providing stronger support.

[0032] The locking structure 8 includes a slot 9 located on one of the second ends of the first rod 6 and the second rod 7, and a buckle 10 located on the other. When the folding lever 3 is folded, the buckle 10 disengages from the slot 9, and the hinge angle between the first rod 6 and the second rod 7 continuously decreases, causing them to move closer together. When the folding lever 3 is unfolded, the buckle 10 engages with the slot 9, thereby limiting the unfolding angle between the first rod 6 and the second rod 7 (that is, when the buckle 10 engages with the slot 9, this is the maximum unfolding angle between the first rod 6 and the second rod 7). This locking structure 8 uses the buckle 10 method, which facilitates fastening and disengagement.

[0033] The top or bottom of the slot 9 is set as an opening 11, and the buckle 10 includes a slope 12 that gradually extends into the slot 9. When the folding lever 3 is folded, the slope 12 disengages from the slot 9, and when the folding lever 3 is unfolded, the slope 12 engages with the slot 9. This locking structure 8 is simple, and the slope 12 of the buckle 10 makes it easier to connect and separate the buckle 10 from the slot 9.

[0034] The second end of the first rod 6 is located inside the second end of the second rod 7, the slot 9 is located at the top of the second end of the second rod 7, and the inclined surface 12 is located on the second end of the first rod 6 and gradually extends from the inside to the slot 9. This arrangement makes the locking structure 8 reasonably laid out and compact.

[0035] The top of the end cap 1 is closed, and the bottom extends inward to form a receiving cavity 4 for accommodating the upper ends of the three support legs 2. The receiving cavity 4 has three limiting parts 5, and the upper ends of the three support legs 2 are respectively hinged within the three limiting parts 5 of the receiving cavity 4. In this embodiment, the three limiting parts 5 are evenly distributed along the circumferential direction to make the three support legs 2 more balanced when unfolded. This end cap 1 structure not only simplifies the structure by installing the three support legs 2 in the same receiving cavity 4, but also utilizes the limiting parts 5 within the receiving cavity 4 to allow each support leg 2 to move within a defined range without interference.

[0036] The two ends of the folding rod 3 are respectively connected to the upper part of two adjacent support legs 2. This arrangement not only reduces the length of the folding rod 3, but also allows the support legs 2 to unfold at a suitable angle, thus making the support legs 2 more stable after unfolding.

[0037] The working principle of the folding tripod in this embodiment is as follows:

[0038] When in use, open the three support legs 2, and the folding rod 3 unfolds along with the support legs 2. During the unfolding process, the buckle 10 on the first rod 6 is inserted downward into the slot 9 on the second rod 7. When the buckle 10 is in place in the slot 9, the folding rod 3 is fully unfolded and remains in the unfolded position. At this time, the three folding rods 3 form a stable triangular support on the three support legs 2, which makes the overall structure more stable when bearing weight and makes the overall structure less prone to movement when under force.

[0039] When folded, the three legs 2 are closed, the buckle 10 on the first rod 6 of the folding lever 3 disengages upward from the slot 9 on the second rod 7, and the folding lever 3 is folded along the middle and stored between the two adjacent legs 2, greatly reducing the space occupied.
