Detailed Implementation

[0022] The technical solution of this utility model will be further clearly and completely described below with reference to the accompanying drawings and through embodiments. The described embodiments are only some embodiments of this utility model. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0023] like Figure 1-5 As shown, a tripod.

[0024] like Figure 1-5 As shown, a tripod includes a fixed rod 1, a sliding sleeve 2 slidably mounted on the fixed rod 1, and at least three legs 3 hinged to the sliding sleeve 2 that can retract towards the central axis of the fixed rod 1. A connecting member 4 is provided at the bottom of the fixed rod 1, and a transmission link 5 is provided between the connecting member 4 and the legs 3. The transmission link 5 includes a link body 51 and a first connecting portion 52 and a second connecting portion 53 located at both ends of the link body 51. The first connecting portion 52 is hinged to the middle of the legs 3, and the middle of the second connecting portion 53 is hinged to the connecting member 4. A pressure cap 7 is provided at the bottom of the connecting member 4. A first elastic member 6 is provided between the pressure cover 7 and the second connecting part 53. The first elastic member 6 has the tendency to rotate the transmission connecting rod 5 around the hinge position of the second connecting part 53 and to move the first connecting part 52 away from the fixed rod 1. A button 9 is provided at the bottom of the pressure cover 7 that can move up and down. A second elastic member 8 is provided between the pressure cover 7 and the button 9. The second elastic member 8 has the tendency to move the button 9 away from the pressure cover 7 along the central axis of the connecting post 41. A button hook 91 is provided on the outside of the button 9. A fixing hook 31 is provided at the bottom of the support leg 3. The fixing hook 31 is elastically engaged with the button hook 91.

[0025] like Figure 2-5As shown, both the first elastic member 6 and the second elastic member 8 can be elastic mechanical components, such as compression springs, torsion springs, etc. In this embodiment, both the first elastic member 6 and the second elastic member 8 are compression springs. The bottom of the connecting member 4 is provided with a connecting post 41. The first elastic member 6, the pressure cover 7, the second elastic member 8 and the button 9 are movably inserted through the connecting post 41 from top to bottom. The top end of the first elastic member 6 elastically abuts against the bottom of the second connecting part 53 away from the connecting rod body 51, and its bottom end elastically abuts against the pressure cover 7. The top end of the second elastic member 8 elastically abuts against the pressure cover 7, and its bottom end elastically abuts against the button 9.

[0026] like Figure 1-2 As shown, the legs 3 are evenly distributed around the outer periphery of the fixed rod 1. The legs 3 have two states: folded and supported. When the bottom of the legs 3 moves towards the central axis of the fixed rod 1, so that the legs 3 are completely folded around the outer periphery of the fixed rod 1, the legs 3 form a tubular structure that can be used as a handle for easy gripping. Since the overall structure is small when folded, it is also easy for users to store. When the bottom of the legs 3 moves away from the central axis of the fixed rod 1, so that the bottom of the legs 3 can all abut against the same plane as the table, the legs 3 are in a supported state and can be used as a tripod.

[0027] like Figure 3 As shown, when the tripod is in the folded state, the end of the second connecting part 53 away from the main body 51 of the connecting rod will compress the first elastic member 6, and the fixing hook 31 at the bottom of the support leg 3 will engage with the button hook 91. In use, the user pushes the button 9 upwards, causing the button hook 91 to separate from the fixing hook 31. At this time, under the action of elastic potential energy, the second elastic member 8 will push the end of the second connecting part 53 away from the main body 51, causing the transmission connecting rod 5 to rotate around the hinge position of the second connecting part 53 and move the first connecting part 52 away from the fixed rod 1. During the process of moving away from the fixed rod 1, the first connecting part 52 will... The support leg 3, which is hinged to the fixed rod 1, unfolds away from the central axis (the bottom of the support leg 3 moves away from the central axis of the fixed rod 1). During the movement, the support leg 3 pulls the sliding sleeve 2, which is hinged to it, to slide downward on the fixed rod 1. When the bottom of the support leg 3 is in contact with a certain plane, it can be used as a tripod. After use, the support leg 3 is manually retracted, so that the bottom of the support leg 3 moves towards the central axis of the fixed rod 1. When the fixed hook 3 is elastically engaged with the button hook 91, the tripod is retracted, and all components return to the retracted state.

[0028] The tubular structure formed by the legs 3 can be square or round, etc.

[0029] like Figure 3-5As shown, in order to better cooperate with the compression spring, the second connecting part 53 and the first connecting part 52 are set at a certain angle, which can be 60 degrees, 90 degrees, 120 degrees, etc.; the end of the second connecting part 53 away from the connecting rod body 51 is provided with an anti-disengagement hook 531, which is movably engaged with the top of the first elastic member 6 to prevent the first elastic member 6 from disengaging from the second connecting part 53.

[0030] like Figure 5 As shown, the top of the pressure cap 7 is provided with a first fixing groove 71, the bottom of the first elastic member 6 is embedded in the first fixing groove 71, the bottom of the pressure cap 7 is provided with a first fixing groove 71, and the top of the second elastic member 8 is embedded in the second fixing groove 72.

[0031] like Figure 5 As shown, the button 9 includes a main body shell 92, the button hook 91 is disposed at the bottom of the outer side of the main body shell 92, and the main body shell 92 is surrounded by connecting parts 4 to form a cavity. The first elastic member 6, the pressure cover 7 and the second elastic member 8 are all disposed in the cavity. The main body shell 92 is provided with a movable groove 921, the transmission connecting rod 5 is movably inserted into the movable groove 921, and the second connecting part 53 passes through the movable groove 921 and is hinged to the connecting part 4 in the middle.

[0032] like Figure 5 As shown, a connecting hole 922 is provided through the center of the main body shell 92. The inner diameter of the connecting hole 922 is larger than the outer diameter of the connecting post 41. The bottom of the connecting post 41 is movably inserted into the connecting hole 922, allowing the main body shell 92 to move up and down along the connecting post 41. A fixing screw 923 is provided on the outside of the bottom of the connecting hole 922. The fixing screw 923 is fixed to the bottom of the connecting post 41. The outer diameter of the nut of the fixing screw 923 is larger than the inner diameter of the connecting hole 922 to prevent the main body shell 92 from falling off the connecting post 41.

[0033] like Figure 1 and 5 As shown, the bottom of the main body shell 92 is also provided with a button protrusion 93, which makes it convenient for the user to press the button 9.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
