[0034] like Figures 1-4 As shown in the figure, an embodiment of the present invention provides a support frame, including a support rod 100, a sliding seat 200 slidable relative to the support rod 100, and support legs 300 that can be unfolded and retracted relative to the support rod 100. The sliding seat 200 is slidably connected to the support rod 100 and can slide along the axial direction of the support rod 100. Multiple support legs 300 are provided. Each support leg 300 is rotatably connected to the sliding seat 200, with its first end rotatably connected to the sliding seat 200. The multiple support legs 300 can be evenly distributed around the circumference of the sliding seat 200. The sliding seat 200 can be annular and fitted around the support rod 100. The support rod 100 can be a telescopic lifting rod. The support rod 100 is connected to a locking assembly 400 for locking and unlocking the legs 300. The locking assembly 400 can lock or unlock the legs 300. When locked, the legs 300 remain locked and against the support rod 100. The support tripod is rod-shaped for easy handheld use as a selfie stick and for storage. When unlocked, the legs 300 can be extended, and each leg 300 can touch the ground, allowing the support tripod to be used as a tripod. The support frame also includes a pull rod 500. The first end of the pull rod 500 is rotatably connected to the support leg 300, and the second end of the pull rod 500 is rotatably connected to the locking seat assembly 400 or the support rod 100. An elastic member 600 is provided between the pull rod 500 and the support leg 300. The elastic member 600 elastically abuts against the support leg 300 and the pull rod 500. When the support leg 300 is retracted to the support rod 100, the elastic member 600 is pre-compressed and elastically deformed. When the support leg 300 is retracted, the elastic member 600 accumulates elastic potential energy. In this way, the support leg 300 can be directly subjected to the force of the elastic member 600. When the support leg 300 is unlocked, the elastic potential energy of the elastic member 600 causes the support leg 300 to unfold directly outward. The unfolding angle of the support leg 300 is large, which is convenient for users.

[0035] like Figure 5 , 7As shown, specifically, the lock seat assembly 400 also includes a seat body 420, which is fixedly or integrally connected to the other end of the support rod 100. The lock body 410 is slidably connected to the seat body 420, and an elastic element 430 is provided between the lock body 410 and the seat body 420 for sliding the lock body 410 to the locked position. The second end of the pull bar 500 is rotatably connected to the seat body 420. The elastic element 430 can be a compression spring, which elastically abuts against the lock body 410. When the user presses the lock body 410 directly or indirectly, the lock body 410 slides towards the seat body 420 and further compresses the elastic element 430, causing the lock body 410 to slide to the unlocked state. When the user releases the lock body 410, the lock body 410 slides away from the seat body 420 under the reset action of the elastic element 430, causing the lock body 410 to return to the locked state.

[0036] like Figure 3 , 5 As shown, specifically, the lock body 410 has multiple locking grooves 411 on the side away from the base 420, and each support leg 300 has a locking hook 320 at the end away from the sliding base 200 that can be engaged in the locking groove 411. The locking groove 411 can be a V-shaped groove or a trapezoidal groove, etc., and the locking hook 320 can be a V-shaped protrusion or a trapezoidal protrusion. Specifically, the latch structure includes an unlocking member 450, which is rotatably or slidably connected to the lock body 410. The unlocking member 450 has a locked position and an unlocked position. When the unlocking member 450 is in the unlocked position, the unlocking member 450 is linked with the lock body 410. That is, when the unlocking member 450 is pressed, the lock body 410 can be switched to the unlocked state, and the support leg 300 can be unfolded outward.

[0037] like Figure 5 , 7 As shown, specifically, the lock body 410 is disposed between the unlocking member 450 and the base 420. The base 420 is provided with an unlocking hole 421, and the unlocking member 450 is provided with a limiting post 451. When the unlocking member 450 is rotated to the unlocked position, the limiting post 451 is aligned with the unlocking hole 421, the unlocking member 450 can be pressed, the limiting post 451 can enter the unlocking hole 421, and the unlocking member 450 can slide to drive the lock body 410 to switch to the unlocked state. When the limiting post 451 is not aligned with the unlocking hole 421, the limiting post 451 abuts against the seat 420 and cannot be pressed. The unlocking member 450 cannot drive the seat 20. That is, the unlocking member 450 can rotate to switch to the locked state (the limiting post 451 is aligned with the unlocking hole 421, and the unlocking member 450 can slide along the axis of the support rod 100) and the unlocked state (the limiting post 451 is not aligned with the unlocking hole 421, the limiting post 451 is aligned with the unlocking hole 421, and the unlocking member 450 cannot slide along the axis of the support rod 100).

[0038] In specific applications, such as Figures 1 to 4As shown, the elastic member 600 can be a torsion spring, which has good elasticity and the lever arm can be designed to be longer, so that the support leg 300 can maintain a stable (maximum) unfolding angle, and the support leg 300 has good stability.

[0039] Specifically, such as Figures 2-4 As shown, the first end of the pull bar 500 is rotatably connected to the inner side of the support leg 300 via a pivot structure. The elastic member 600 is located at the pivot structure, resulting in a compact structure where the elastic member 600 and the pivot structure are not exposed, giving the product an aesthetically pleasing appearance. The support leg 300 can be in the shape of an arc-shaped sheet, which can rest against the outer periphery of the support rod 100.

[0040] Specifically, such as Figure 6 , 10 As shown, the torsion spring includes a collar portion 610, a first elastic arm 620, and a second elastic arm 630. The collar portion 610, the first elastic arm 620, and the second elastic arm 630 can be integrally formed from spring steel wire. That is, the elastic component includes the collar portion 610, the first elastic arm 620, and the second elastic arm 630, all integrally connected to the collar portion 610. The collar portion 610 is fitted onto the rotating shaft structure. The first elastic arm 620 abuts against the pull rod 500, and the second elastic arm 630 abuts against the inner side of the support leg 300, resulting in good structural reliability. The pull rod 500 can be a metal part, which can be in the form of a thin sheet. The pull rod 500 can also be made of a plastic sheet with good elasticity.

[0041] Specifically, such as Figure 6 As shown, the pivot structure includes a first pivot 710 connected to both ends of the support leg 300. The first end of the pull bar 500 is rotatably connected to the middle of the first pivot 710. Two collar portions 610 are provided and are respectively located on both sides of the first end of the pull bar 500. The first elastic arm 620 is a rectangle with an open bottom (roughly U-shaped, but in specific applications, it can be an inverted U-shape, etc.). The lower end of the first elastic arm 620 is integrally connected between the two collar portions 610. When the support leg 300 is retracted, the first side of the pull bar 500 faces the inside of the support leg 300. The first elastic arm 620 abuts against the first side of the pull bar 500. The second elastic arm 630 abuts against the inside of the support leg 300. Two second elastic arms 630 can be provided. The first elastic arm 620 includes a transverse portion and two longitudinal portions. The transverse portion of the first elastic arm 620 is attached to the pull bar 500, and the two longitudinal portions are integrally connected to the two collar portions 610 respectively.

[0042] Specifically, such as Figure 3 , 6As shown, the inner side of the support leg 300 is provided with a receiving groove 301 for at least partially accommodating the pull bar 500. When the support leg 300 is folded into the support rod 100, the pull bar 500 is at least partially accommodated in the receiving groove 301. The two second elastic arms 630 are close to the two sides of the receiving groove 301 in the width direction, resulting in a compact structure. The two sides of the receiving groove 301 are provided with slots 303 for accommodating the two ends of the first rotating shaft 710. The slots 303 have openings. The support leg 300 is fixedly connected with a limiting member 770 for sealing the openings to prevent the first rotating shaft 710 from loosening, so as to facilitate assembly. The limiting member 770 can be a plastic part or a metal part. The limiting member 770 can be connected to the inner side of the support leg 300 by means of adhesive, screw fixing, etc.

[0043] like Figure 4 , 7 As shown, specifically, the lock seat assembly 400 includes a lock body 410 disposed on the support rod 100 and movable between a locked position and an unlocked position. A latch structure is provided between the lock body 410 and the support leg 300. When the lock body 410 is in the locked position, the support leg 300 is locked to the lock body 410 by the latch structure and remains in a retracted state, ensuring that the support leg 300 will not automatically pop open after being accidentally touched, and the support leg 300 always remains in a retracted state. When the lock body 410 is in the unlocked position, the support leg 300 is disengaged from the lock body 410 and unfolds under the action of the elastic member 600 and the pull bar 500 and remains in an unfolded state. In the retracted state, the user can directly press the lock body 410 to move the lock body 410 towards the unlocked position, thereby releasing the lock on the support leg 300, and then causing the support leg 300 to unfold under the action of the torsion spring, driving the pull bar 500 to slide the sliding seat 200 down along the support rod 100, so that the support leg 300 automatically unfolds.

[0044] like Figure 4 As shown, specifically, one end of the support rod 100 is provided with a clamping component 800 for clamping the mobile terminal. The clamping component 800 can be an elastic clamp, which can be housed in the receiving cavity of the housing. Of course, the clamping component 800 can also adopt other suitable structures.

[0045] like Figure 3 , 4 As shown, specifically, each support leg 300 has a ground-inserting pin 900 extending from the end of the sliding seat 200. The ground-inserting pin 900 is rotatably or slidably connected to the support leg 300 and can be folded back inside the support leg 300. The end of the ground-inserting pin 900 can be spike-shaped. The ground-inserting pin 900 can rotatably or slidably extend out of the support leg 300 and be inserted into a support surface such as grass, making it suitable for uneven support surfaces and providing good applicability. The ground-inserting pin 900 can be U-shaped or other suitable shapes. Alternatively, the ground-inserting pin 900 can also be straight, L-shaped, or E-shaped, all of which fall within the protection scope of this utility model.

[0046] likeFigure 3 , 4 As shown, specifically, the grounding pin 900 is rotatably connected to the support leg 300. A limiting structure is provided between the support leg 300 and the grounding pin 900. The support leg 300 may be provided with an inclined surface. When the grounding pin 900 rotates and extends out of the support leg 300, the grounding pin 900 can abut against the inclined surface, thereby limiting the rotation of the grounding pin 900. The grounding pin 900 can be perpendicular to the insertion surface, resulting in good stability.

[0047] like Figure 3 , 4 As shown, specifically, the inner side of the support leg 300 is provided with a slot for receiving the grounding pin 900, and the inner side of the support leg 300 is provided with a buckle 330 for limiting the grounding pin 900, so as to facilitate the storage of the grounding pin 900.

[0048] like Figure 2 As shown, specifically, the two ends of the pull bar 500 are integrally formed or fixedly provided with rings (which can be bent into shape), and both ends of the pull bar 500 are provided with rotating shafts to facilitate assembly.

[0049] The present invention provides a support stand with a locking seat assembly 400 that can lock or unlock the legs 300. When the legs 300 are locked, they remain locked and abut against the support rod 100. The support stand is rod-shaped for easy hand-holding and storage. When the legs 300 are unlocked, they can be unfolded and each leg 300 can touch the ground for use. The support frame also includes a pull rod 500. The first end of the pull rod 500 is rotatably connected to the support leg 300, and the second end of the pull rod 500 is rotatably connected to the locking seat assembly 400 or the support rod 100. An elastic member 600 is provided between the pull rod 500 and the support leg 300. The elastic member 600 elastically abuts against the support leg 300 and the pull rod 500. When the support leg 300 is retracted to the support rod 100, the elastic member 600 is pre-compressed and elastically deformed. When the support leg 300 is retracted, the elastic member 600 accumulates elastic potential energy. In this way, the support leg 300 can be directly subjected to the force of the elastic member 600. When the support leg 300 is unlocked, the elastic potential energy of the elastic member 600 causes the support leg 300 to unfold directly outward. The unfolding angle of the support leg 300 is large, which is convenient for users.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
