The supporting leg 100 can be folded to reduce the occupied volume of the supporting component 200, and meanwhile, the folding of the supporting leg 100 is very convenient and the operation is simple. For convenience of assembly, the connection portion 130 is detachably connected to each of the support legs 100. Specifically, the supporting leg 100 is provided with a first mounting hole 101, the connecting portion 130 is provided with a second mounting hole 131, a spring piece is arranged in the second mounting hole 131, and the connecting portion 130 extends into the first mounting hole 101 and is detachably connected with the first mounting hole through the action of the spring piece, so that the connecting portion 130 and the supporting leg 100 are conveniently and rapidly assembled to form the supporting assembly 200. In this embodiment, four supporting legs 100 and four connecting portions 130 are adopted to form the supporting assembly 200, each two supporting legs 100 are connected through one connecting portion 130, the connecting portions 130 are in an arc structure, so as to increase the stress of the supporting assembly 200, and the four connecting portions 130 are circular after being connected with the four supporting legs 100.
Referring to fig. 4 to 9, the support foot 100 includes an upper joint 10, a lower joint 30, and an elastic member 50. The first mounting hole 101 is provided at the upper joint 10. One of the lower joint 30 and the upper joint 10 has a locking portion 31, and the other of the lower joint 30 and the upper joint 10 has a limiting groove 13 into which the locking portion 31 extends. In the present embodiment, the locking portion 31 is provided on the lower joint 30, the limit groove 13 is provided on the upper joint 10, but the present invention is not limited thereto, and the limit groove 13 may be provided on the lower joint 30, and the locking portion 31 may be provided on the upper joint 10, thereby achieving the effects of the present invention. The locking portion 31 is provided with a long groove 36 for sliding the fixed shaft 11, the fixed shaft 11 passes through the long groove 36 and is rotatably connected, and the limiting groove 13 is used for limiting the pivoting angle of the lower joint 30 around the upper joint 10, and the lower joint 30 is operated to rotate around the fixed shaft 11. The fixed shaft 11 is disposed on the same side as the limit groove 13, and in this embodiment, the upper joint 10 is provided with the fixed shaft 11. One end of the elastic member 50 is mounted on the upper joint 10, the other end of the elastic member 50 is mounted on the lower joint 30, the elastic member 50 constantly enables the locking portion 31 to be clamped in the limiting groove 13, that is, the elastic member 50 provides elastic force to constantly move the locking portion 31 along the limiting groove 13, the lower joint 30 is operated to overcome the elastic force of the elastic member 50 so that the locking portion 31 is separated from the limiting groove 13 to a certain position, and the lower joint 30 can be operated to rotate around the fixed shaft 11 to fold the lower joint 30 relative to the upper joint 10. Thus, when the support foot 100 is not required, for example: the lower joint 30 is pulled downwards, that is, the lower joint 30 is pulled to move in the arrow direction K (as shown in fig. 5), so that the lower joint 30 moves to a certain position, and the position can be designed according to practical situations, and can reach a rotatable position, which is not limited herein. When the lower joint 30 moves to a position where the lower joint 30 can rotate around the fixed shaft 11, the lower joint 30 is operated to fold inwards, so that the lower joint 30 is folded relative to the upper joint 10, and the folding process is convenient. Also, due to the folding of the support legs 100, the occupied volume thereof is reduced, and the transportation and carrying are convenient. In the present embodiment, the elastic member 50 adopts a tension spring, and the elongated slot 36 adopts an elliptical structure, but not limited thereto.
Referring to fig. 5 to 6, the locking portion 31 includes a first locking portion 311 and a second locking portion 313, the long slot 36 includes a first long slot 361 provided in the first locking portion 311 and a second long slot 363 provided in the second locking portion 313, and the fixed shaft 11 penetrates the first long slot 361 and the second long slot 363. By providing two locking portions 31, the stability of the pivoting and supporting of the lower joint 30 is improved. Further, a movable space 35 of the elastic member 50 is provided between the first locking portion 311 and the second locking portion 313, one end of the elastic member 50 is connected to the fixed shaft 11, the other end of the elastic member 50 is connected to the lower joint 30, and the elastic member 50 is provided between the first locking portion 311 and the second locking portion 313, thereby improving stability of support. In order to secure the stability of the installation of the elastic member 50, the lower joint 30 has a fixing post 32, one end of the elastic member 50 is connected to the fixing shaft 11, and the other end of the elastic member 50 is connected to the fixing post 32. In particular, the lower joint 30 has a first limiting plate 33 and a second limiting plate 34, and the first limiting plate 33, the second limiting plate 34 and the fixed column 32 enclose a movable space 35 for the elastic member 50, so as to avoid the elastic member 50 from separating.
Referring to fig. 5, the limiting slot 13 is provided with an opening 14, the fixing shaft 11 passes through the limiting slot 13, the locking portion 31 is separated from the limiting slot 13 to a certain position, and the lower joint 30 can be operated to fold up on the upper joint 10 along the direction of the opening 14. The opening 14 not only makes the structure of the supporting leg 100 compact, but also makes the pivoting of the lower joint 30 around the fixed shaft 11 smooth.
The principle of operation of the support foot 100 of the present application is described in detail below with reference to fig. 1-9.
When the support foot 100 is in the use state (as shown in fig. 1 or fig. 7), the top ends of the first locking portion 311 and the second locking portion 313 abut against the limiting groove 13, and the elastic member 50 constantly enables the first locking portion 311 and the second locking portion 313 to be engaged with the limiting groove 13, so that the upper joint 10 and the lower joint 30 are located on the same straight line in the vertical direction, and a supporting effect can be provided. When the support leg 100 is not needed, the lower joint 30 is pulled downward in the arrow direction K (as shown in fig. 5), the locking portion 31 is separated from the limiting groove 13 to a certain position, i.e., a position that can be folded along the direction of the opening 14 (as shown in fig. 5 or 8), and then the lower joint 30 is operated to be folded on the upper joint 10 along the direction of the opening 14, so that the lower joint 30 is folded relative to the upper joint 10 (as shown in fig. 2 or 9), and the folding is convenient.
Compared with the prior art, the locking part 31 stretches into the limiting groove 13, the fixed shaft 11 and the long groove 36 are in relative sliding and rotating connection, meanwhile, the elastic piece 50 enables the locking part 31 to be clamped in the limiting groove 13 constantly, and the limiting groove 13 is used for limiting the pivoting angle of the lower joint 30 around the upper joint 10, so that the upper joint 10 and the lower joint 30 are mutually supported. Because the fixed shaft 11 can slide relatively in the long groove 36, the lower joint 30 is operated to overcome the elastic force of the elastic member 50, and the long groove 36 is driven to move downwards, so that the locking part 31 is separated from the limiting groove 13 to reach a certain position, at which the lower joint 30 can be operated to pivot around the fixed shaft 11 to rotate relative to the upper joint 10, thereby realizing the folding of the lower joint 30 relative to the upper joint 10, and the folding is convenient.
The invention has been described in connection with the preferred embodiments, but the invention is not limited to the embodiments disclosed above, but it is intended to cover various modifications, equivalent combinations according to the essence of the invention.
