[0028] like Figures 1 to 3As shown, a self-opening portable stand has good shrinkage and folding ability, can effectively reduce the volume after folding, and is easy to carry. At the same time, the support legs 3 can be automatically opened when in use, which is convenient for users to unfold and use, and can ensure the work efficiency of users. The self-opening portable stand of this embodiment includes a telescopic rod group 1, a connecting component 2 connected to the top of the telescopic rod group 1, and three support legs 3 connected to the bottom of the telescopic rod group 1, wherein the telescopic rod group 1 of this embodiment includes a plurality of hollow structure sleeve rods 11 that are sequentially sleeved from the inside to the outside, the connecting component 2 of this embodiment is connected to the top of the innermost sleeve rod 11, and the three support legs 3 are connected to the outermost sleeve rod 11, so that when the user uses it, the three support legs 3 located at the bottom of the telescopic rod group 1 can be opened to form a stable support platform, and at the same time, equipment such as video cameras and cameras can be installed on the connecting component 2 at the top of the telescopic rod group 1, so as to facilitate the user to use. Furthermore, when the bracket is in use, the sleeve rods 11 of the telescopic rod group 1 can be pulled out to increase the length of the bracket, thereby facilitating adjustment of the height of the device to obtain a better user experience; when the bracket is carried, the sleeve rods 11 of the telescopic rod group 1 can be retracted to reduce the volume of the bracket for easy carrying.

[0029] like Figures 1 to 3 As shown, the telescopic rod group 1 of this embodiment is movably provided with a movable sleeve 4, one end of each supporting leg 3 is hinged at the bottom of the movable sleeve 4, and at the same time, an automatic pop-up component 5 is connected between the bottom of the telescopic rod group 1 and the supporting leg 3, so that when the movable sleeve 4 moves along the telescopic rod group 1, the supporting legs 3 can be gathered together and surrounded by the outside of the telescopic rod group 1 or simultaneously unfolded to form a supporting platform under the action of the automatic pop-up component 5, which is convenient for use; and the automatic pop-up component 5 can also automatically pop open each supporting leg 3 when the bracket is unfolded and used, without the user manually opening the supporting leg 3 for support, which is convenient for the user to unfold the bracket for use and can ensure the user's work efficiency.

[0030] Specifically, Figure 3As shown, the automatic pop-up component 5 of this embodiment includes a connecting rod 52 and an unfolding spring 51, wherein the two ends of the connecting rod 52 are respectively hinged at the inner middle part of the supporting leg 3 and the bottom of the outermost sleeve rod 11 of the telescopic rod group 1. When the movable sleeve 4 moves along the telescopic rod group 1, the supporting legs 3 hinged to the movable sleeve 4 can be simultaneously retracted and surrounded by the outer side of the telescopic rod group 1 or simultaneously unfolded at the same angle under the drive of the connecting rod 52, which is convenient for folding or unfolding the bracket. In order to realize the automatic deployment of the three supporting legs 3 in this embodiment, one end of the deployment spring 51 is connected to the inner top of the supporting leg 3, and the other end of the deployment spring 51 is connected to the middle part of the connecting rod 52. When the supporting leg 3 is deployed, the deployment spring 51 is in a relaxed state. Therefore, when the movable sleeve 4 moves up along the telescopic rod group 1 to retract the supporting leg 3, the distance between the top of the supporting leg 3 and the middle part of the connecting rod 52 increases, thereby stretching and tightening the deployment spring 51 connected at the two positions. When the user uses the bracket, the deployment spring 51 can retract under the action of elasticity and drive the supporting leg 3 and the connecting rod 52 to rotate and open, thereby realizing the automatic deployment of the supporting leg 3, which is convenient for the user to use.

[0031] like Figures 2 to 4 As shown, in order to prevent the supporting legs 3 that are gathered together and surrounded on the outside of the telescopic rod group 1 from bouncing apart under the action of the unfolding spring 51 when the bracket is stored, a locking sleeve 6 is provided at the bottom of the connecting component 2 in this embodiment, and a locking groove 41 is provided at the top of the movable sleeve 4. After the movable sleeve 4 moves upward along the telescopic rod group 1 to drive the supporting legs 3 to gather and surround the outside of the telescopic rod group 1, the locking sleeve 6 at the bottom of the connecting component 2 is inserted into the locking groove 41, thereby locking the movable sleeve 4 to prevent the movable sleeve 4 from moving, so that the supporting legs 3 can remain in a retracted and gathered state.

[0032] Specifically, Figure 4 As shown, the locking sleeve 6 of this embodiment is provided with a plurality of slots 42 at equal intervals on the inner wall thereof, and a plurality of hooks 61 are provided at equal intervals on the outer wall of the locking sleeve 6 where the locking sleeve 6 is inserted into the locking slot 41. After the locking sleeve 6 is inserted into the locking slot 41 and rotated, the hooks 61 on the outer wall of the locking sleeve 6 can be engaged with the slots 42, thereby locking the movable sleeve 4, preventing the movable sleeve 4 from moving along the telescopic rod group 1 and causing the support legs 3 to unfold, thereby ensuring the stability of the bracket when folding and contracting.

[0033] Further, such as Figure 4As shown, in order to further improve the stability of the bracket after folding and prevent the movable sleeve 4 from loosening and causing the supporting leg 3 to automatically unfold when the locking sleeve 6 is accidentally touched, the present embodiment further provides a connecting seat 7 at the bottom of the connecting assembly 2, wherein the bottom of the connecting seat 7 is inserted into the locking sleeve 6, and a torsion spring 8 is installed on the portion of the connecting seat 7 inserted into the locking sleeve 6, one end of the torsion spring 8 is connected to the connecting seat 7, and the other end of the torsion spring 8 is connected to the inner wall of the locking sleeve 6, so that the locking sleeve 6 can keep the hook 61 on its surface engaged in the slot 42 under the elastic force of the torsion spring 8, thereby preventing the locking sleeve 6 from easily rotating and causing the supporting leg 3 to automatically unfold. When the bracket needs to be unfolded for use, it is only necessary to rotate the locking sleeve 6 to overcome the elastic force of the torsion spring 8 and then disengage the hook 61 from the slot 42, so that the movable sleeve 4 can be unlocked and moved along the telescopic rod group 1 under the drive of the unfolding spring 51 to realize the automatic unfolding of each supporting leg 3.

[0034] like Figure 3 As shown, the inner side of the support leg 3 of the present embodiment is provided with an enclosing groove 31 adapted to the outermost sleeve rod 11 of the telescopic rod group 1. When the bracket is stored so that the support leg 3 is enclosed on the outside of the telescopic rod group 1, the outermost sleeve rod 11 of the telescopic rod group 1 can be embedded in the enclosing groove 31 on the inner side of the three support legs 3, which can effectively reduce the volume of the bracket after folding and facilitate carrying; at the same time, a storage groove 32 is also provided in the enclosing groove 31 of the present embodiment, so that the connecting rod 52 and the unfolding spring 51 for automatically unfolding the support leg 3 can be embedded in the storage groove 32 when the support leg 3 is contracted and gathered, thereby avoiding interference with the contraction and gathering of the support leg 3 and ensuring the normal contraction of the support leg 3.

[0035] like Figure 2 and Figure 4 As shown, in order to facilitate the adjustment of the equipment connected to the bracket, the connecting component 2 of this embodiment includes a ball socket 21 fixedly connected to the top of the telescopic rod group 1 and a ball head 22 movably connected in the ball socket 21. The ball head 22 of this embodiment is connected to a connecting piece 23. Video cameras, cameras and other equipment can be installed on the top of the bracket through the connecting piece 23, and various angles and positions can be adjusted by rotating the ball head 22 in the ball socket 21, so that users can have a better usage experience.

[0036] Among them, the connecting member 23 of this embodiment includes a connecting seat 7 fixedly connected to the top of the ball head 22, an adjusting knob installed in the connecting seat 7 for transverse rotation, and a connecting column connected to the center of the adjusting knob and extending from the surface of the connecting seat 7. When connecting equipment such as a video camera and a camera, the connecting column can be rotated by adjusting the knob so that the connecting column can be threadedly connected to the connecting holes of various equipment. The connection method is convenient and suitable for connecting a variety of equipment, and has a wide range of applications.

[0037] like Figure 4As shown, one side of the ball socket 21 of the present embodiment is also provided with a locking screw 24 which is inserted into the interior of the ball socket 21 and abuts against the surface of the ball head 22. After the device is installed and the position is adjusted through the ball head 22, the position of the ball head 22 can be fixed by the locking screw 24 abutting against the surface of the ball head 22, so that the connected device can maintain the adjusted angle and position to work.

[0038] At the same time, a rotating handle 25 is fixedly installed on the locking screw 24 of this embodiment. The user can rotate the locking screw 24 by rotating the handle 25, so that the locking screw 24 abuts against the surface of the ball head 22 to lock it or moves away from the ball head 22 to loosen it, which is convenient for the user to adjust.

[0039] like Figure 1 and Figure 5 As shown, the present embodiment forms a telescopic rod set 1 by providing a plurality of sleeve rods 11 which are sleeved from the inside to the outside in sequence, and two adjacent sleeve rods 11 are telescopically movable, so that the user can adjust the height of the bracket by pulling out each sleeve rod 11 in sequence, and when the use is completed and the sleeve rods 11 are folded and stored, each sleeve rod 11 can also be retracted in sequence to reduce the overall volume of the bracket, which is convenient for carrying. In order to achieve stable telescopic movement between each sleeve rod 11 of the present embodiment, a vertically arranged guide groove 111 is arranged on the outer wall of each sleeve rod 11, and a guide protrusion 112 is arranged at a position corresponding to the guide groove 111 on the inner wall of the sleeve rod 11. When each sleeve rod 11 is sleeved in sequence, the guide protrusion 112 on the inner wall of the sleeve rod 11 located on the outside can be movably engaged in the guide groove 111 on the outer wall of the sleeve rod 11 located on the inside, so that the telescopic movement of the sleeve rod 11 can be guided, which is convenient for realizing stable telescopic movement of the telescopic rod set 1.

[0040] In summary, the working principle of the present embodiment is as follows: the present embodiment provides a bracket with a telescopic rod group 1, and provides a support leg 3 hinged to a movable sleeve 4 mounted on the telescopic rod group 1 at the bottom of the telescopic rod group 1, so that when the bracket is folded, each support leg 3 can be folded and surrounded by the outside of the telescopic rod group 1, and at the same time, the telescopic rod group 1 can be contracted to shorten the overall length of the bracket, thereby effectively reducing the volume of the bracket after folding, which is convenient for carrying; and, by providing an automatic pop-up component 5 between the bottom of the telescopic rod group 1 and the support leg 3 bracket, when the bracket is unfolded for use, the support leg 3 can automatically pop up under the action of the automatic pop-up component 5, which is convenient for the use of the bracket and can ensure the work efficiency of the user.

[0041] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model.
