[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0052] This utility model embodiment provides a support bracket 1, such as Figures 1 to 15 As shown, the support frame 1 includes a main rod 11, a sliding seat 12, support legs 13, and connecting rods 14. The sliding seat 12 is sleeved on the main rod 11. At least three support legs 13 are provided, each rotatably mounted on the sliding seat 12. At least three connecting rods 14 are provided, with each connecting rod 14 paired with a support leg 13. The two ends of each connecting rod 14 are rotatably connected to the support leg 13 and the main rod 11, respectively. A locking mechanism 15 is provided on the sliding seat 12. The locking mechanism 15 has a locked state and an unlocked state. When the locking mechanism 15 is in the locked state, each support leg 13 is retracted to the outer periphery of the main rod 11, and the locking mechanism 15 contacts the main rod 11 to lock the position of the main rod 11 and the sliding seat 12. When the locking mechanism is in the unlocked state, the sliding seat 12 can slide on the main rod 11, allowing each support leg 13 to extend outward relative to the main rod 11 to form a support structure (see...). Figure 1 ).

[0053] In the support frame 1, multiple connecting rods 14 are paired with multiple legs 13, and the two ends of the connecting rods 14 are rotatably connected to the legs 13 and the main rod 11, respectively, thereby enabling the support structure of the support frame 1 (i.e., Figure 1 The support structure shown (after each support leg 13 is unfolded) has a more stable support function, and the support legs 13 and the main rod 11 are connected by connecting rods 14, so that each support leg 13 can be linked when unfolding outward or retracting inward relative to the main rod 11 (that is, each support leg 13 can simultaneously unfold outward to form a support structure, or simultaneously retract inward to form a retracted structure). During the unfolding or retracting of each support leg 13, since each support leg 13 is rotatably mounted on the sliding seat 12, and each support leg 13 is connected to the main rod 11 through connecting rods 14 to form a linked structure, the sliding seat 12 needs to slide relative to the main rod 11 to ensure the smooth rotation of each support leg 13. Specifically, during the retraction process, the sliding seat 12 moves towards the top of the main rod 11 (e.g., ...). Figure 1 The sliding mechanism (in the direction of arrow A) causes each support leg 13 and connecting rod 14 to rotate towards the main rod 11, thus retracting each support leg 13. During the outward expansion of each support leg 13 relative to the main rod 11, the sliding seat 12 moves towards the bottom of the main rod 11 (e.g., ...). Figure 1The locking mechanism 15 is arranged on the sliding seat 12, so that the locking mechanism 15 is released on the sliding seat 12, and the sliding seat 12 is pushed to slide towards the bottom end of the main rod 11, and the linkage of the supporting legs 13 is realized, so that the supporting legs 13 are more convenient to be unfolded.

[0054] The prior art supporting leg frame (not shown in the figure) is often arranged with a locking mechanism at the bottom end of the main rod, and the supporting leg or the connecting rod is locked with the locking mechanism at the bottom end of the main rod when the supporting leg and the connecting rod are stored (for example, a clamping groove is arranged on the supporting leg, and a clamping convex is arranged at the bottom end of the main rod to match the clamping groove), so that the supporting leg and the connecting rod can be kept in the storage state, and this kind of mode causes that when the supporting leg frame is used, the locking of the locking mechanism at the bottom end of the main rod needs to be released first, and then the sliding seat is slid towards the bottom end of the main rod, and the linkage of the supporting legs is unfolded. The technical scheme of the utility model is that the locking mechanism 15 is arranged on the sliding seat 12, so that the locking mechanism 15 is released on the sliding seat 12, and the sliding seat 12 is pushed to slide towards the bottom end of the main rod 11, and the linkage of the supporting legs 13 is realized, so that the supporting legs 13 are more convenient to be unfolded.

[0055] The utility model discloses a supporting leg frame 1 further includes a pop-up mechanism 16, and the pop-up mechanism 16 stores energy when the locking mechanism 15 is in the locking state. When the locking mechanism 15 is in the unlocking state, the pop-up mechanism 16 releases energy to push the sliding seat 12 to slide on the main rod 11. Therefore, when the locking mechanism 15 does not lock the main rod 11, the sliding seat 12 slides on the main rod 11 through the energy release of the pop-up mechanism 16, and the sliding seat 12 drives the supporting legs 13 to unfold in the sliding process, so that the supporting legs 13 are automatically unfolded to form a supporting structure of the supporting leg frame 1. The energy storage of the pop-up mechanism 16 means that the pop-up mechanism 16 has a force that can push the sliding seat 12 to slide on the main rod 11. The force can directly or indirectly act on the sliding seat 12 or the main rod 11. As long as the force exists when the locking mechanism 15 is in the locking state, the position between the sliding seat 12 and the main rod 11 is not limited when the locking mechanism 15 is in the unlocking state, so that the sliding seat 12 can slide towards the bottom end of the main rod 11 under the action of the force, and the supporting legs 13 are unfolded.

[0056] In an embodiment, referring to Figures 2 to 4, the support stand 1 further comprises a sleeve 17, a first abutting piece 18, a second abutting piece 19, the sleeve 17 is sleeved on the main rod 11, and one end of the sleeve 17 is fixed to the sliding seat 12, the first abutting piece 18 is sleeved on the main rod 11 and is in sliding connection with the main rod 11, the main rod 11 is provided with an abutting portion 111 abutting against the first abutting piece 18, the second abutting piece 19 is arranged at an end of the sleeve 17 away from the sliding seat 12, and the elastic opening mechanism 16 is provided as a first spring 161; the first spring 161 is sleeved on the main rod 11 and located in the sleeve 17, the first spring 161 is arranged between the first abutting piece 18 and the second abutting piece 19, when the locking mechanism 15 is in the locked state, the first abutting piece 18 abuts against the abutting portion 111, and the second abutting piece 19 compresses the first spring 161 to store energy. Specifically, the first abutting piece 18 is sleeved on the main rod 11 and is in sliding connection with the main rod 11, and the abutting portion 111 limits the sliding position of the first abutting piece 18 on the main rod 11, so that the sliding seat 12 can continue to slide on the main rod 11 when the first abutting piece 18 is abutted by the abutting portion 111, and the second abutting piece 19 slides with the sliding of the sliding seat 12, so that the second abutting piece 19 compresses the first spring 161 to store energy in the process of sliding (that is, the first spring 161 is compressed to accumulate elastic potential energy), when each support leg 13 is stored, the locking mechanism 15 is in the locked state, the locking mechanism 15 locks the positions of the main rod 11 and the sliding seat 12, and the sliding of the main rod 11 and the sliding seat 12 is limited, so that each support leg 13 remains in the storage state. When the locking mechanism 15 is in the unlocked state, the locking mechanism 15 releases the locking of the positions of the main rod 11 and the sliding seat 12, so that the main rod 11 and the sliding seat 12 can slide relatively, under the action of the elastic potential energy, the sliding seat 12 slides relative to the main rod 11 towards the bottom end of the main rod 11, so that each support leg 13 is unfolded.

[0057] Referring to Figure 4 , the second abutting piece 19 is a protrusion 171 formed by extending the inner side wall of the sleeve 17 towards the main rod 11; in this way, the protrusion 171 is arranged on the inner side wall of the sleeve 17 and abuts against or fixes the end of the first spring 161, so that the first spring 161 can be stably arranged between the first abutting piece 18 and the second abutting piece 19. Specifically, referring to Figure 5 , a groove 172 is formed in the protrusion 171, and the first spring 161 can be fixed or abutted in the groove 172, so as to facilitate the stable installation of the first spring 161 between the protrusion 171 and the first abutting piece 18.

[0058] In an embodiment, the second abutting piece 19 is a sliding sleeve (not shown in the figure) arranged at one end of the sleeve 17 away from the sliding seat 12. In this way, the sleeve 17 and the second abutting piece 19 are two components and can be processed separately, avoiding damage to the entire sleeve 17 caused by insufficient strength of the protrusion 171 when the sleeve 17 and the second abutting piece 19 are one component.

[0059] In one embodiment, referring to Figure 6 and Figure 7 , the unfolding mechanism 16 is a torsion spring 162 clamped between the leg 13 and the sliding seat 12 or clamped between the leg 13 and the main rod 11. When the locking mechanism 15 is in the locked state, the leg 13 receives and compresses the torsion spring 162 to store energy. When the locking mechanism 15 is in the unlocked state, the torsion spring 162 resets to make the sliding seat 12 slide on the main rod 11, so that each leg 13 unfolds outward relative to the main rod 11 (i.e., the leg 13 rotates relative to the main rod 11, and the end of the leg 13 away from the sliding seat 12 moves away from the main rod 11) to form a support structure. Thus, when the locking mechanism is in the unlocked state, the torsion spring 162 resets to push the leg 13 to unfold outward, and the leg 13 unfolds outward, so that the sliding seat 12 can slide on the main rod 11 without being positionally locked by the locking mechanism 15. The specific installation structure of the torsion spring 162 is not described here, and those skilled in the art can design it according to the actual situation.

[0060] In one embodiment (not shown in the figure), the unfolding mechanism is a torsion spring provided between the main rod 11 and the connecting rod 14. When the locking mechanism 15 is in the locked state, the connecting rod 14 rotates towards the main rod 11 to compress the torsion spring to store energy. When the locking mechanism 15 is in the unlocked state, the torsion spring resets to make the sliding seat 12 slide on the main rod 11, so that each leg 14 unfolds outward relative to the main rod 11 to form a support structure. Thus, when the locking mechanism is in the unlocked state, the torsion spring resets to push the connecting rod 14 to unfold outward (i.e., the connecting rod 14 rotates relative to the main rod 11 and the leg 13, and the end of the connecting rod 14 connected to the leg 13 moves away from the main rod 11), so that each leg 13 also unfolds outward, so that the sliding seat 12 can slide on the main rod 11 without being positionally locked by the locking mechanism 15. In this embodiment, the working principle of the torsion spring is similar to that of the embodiments shown in Figure 6 and Figure 7 , and the only difference is the installation position of the torsion spring.

[0061] In one embodiment, referring to Figure 8, the elastic column 163 is arranged on the main rod 11 or the connecting rod 14, when the locking mechanism 15 is in the locked state, the connecting rod 14 rotates towards the main rod 11 to compress the elastic column 163 to store energy; when the locking mechanism 15 is in the unlocked state, the elastic column 163 resets to make the sliding seat 12 slide on the main rod 11, so that each support leg 13 expands outward relative to the main rod 11 to form a support structure. Thus, when the locking mechanism 15 is in the unlocked state, the elastic column 163 resets to push the connecting rod 14 to expand outward relative to the main rod 11 (i.e. the connecting rod 14 rotates relative to the main rod 11 and the support leg 13, and the end of the connecting rod 14 connected with the support leg 13 moves away from the main rod 11), so that each support leg 13 also expands outward, and then the sliding seat 12 can slide on the main rod 11 when the sliding seat 12 and the main rod 11 are not limited and locked by the locking mechanism 15.

[0062] In an embodiment, referring to Figure 9 , the elastic column 163 is arranged on the main rod 11 or the connecting rod 14, when the locking mechanism 15 is in the locked state, the connecting rod 14 rotates towards the main rod 11 to compress the elastic column 163 to store energy; when the locking mechanism 15 is in the unlocked state, the elastic column 163 resets to make the sliding seat 12 slide on the main rod 11, so that each support leg 13 expands outward relative to the main rod 11 to form a support structure. Thus, when the locking mechanism 15 is in the unlocked state, the elastic column 163 resets to push the connecting rod 14 to expand outward relative to the main rod 11 (i.e. the connecting rod 14 rotates relative to the main rod 11 and the support leg 13, and the end of the connecting rod 14 connected with the support leg 13 moves away from the main rod 11), so that each support leg 13 also expands outward, and then the sliding seat 12 can slide on the main rod 11 when the sliding seat 12 and the main rod 11 are not limited and locked by the locking mechanism 15.

[0063] In an embodiment, referring to Figure 10Further comprising a sleeve 17, the pop-up mechanism 16 is a first magnetic member 166 and a second magnetic member 167, the first magnetic member 166 is slidingly installed on the outer side of the main rod 11, the sleeve 17 is sleeved on the main rod 11, and one end of the sleeve 17 is fixed to the sliding seat 12, the second magnetic member 167 is installed on the end of the sleeve 17 away from the sliding seat 12, and the first magnetic member 166 and the second magnetic member 167 form a repulsive force between the magnetic poles; The main rod 11 is provided with a resisting portion 111 resisting the first magnetic member 166; During the folding process of the support leg 13, the first magnetic member 166 slides on the main rod 11 and is finally abutted by the resisting portion 111, the sleeve 17 slides on the main rod 11 and drives the second magnetic member 167 to move towards the first magnetic member 166 to store energy; The locking mechanism 15 releases the locking of the position of the main rod 11 and the sliding seat 12 in the folding state of the support leg 13, the repulsive force between the magnetic poles of the first magnetic member 166 and the second magnetic member 167 releases energy to push the sliding seat 12 to slide on the main rod 11, so that each support leg 13 is unfolded outward relative to the main rod 11 to form a support structure.

[0064] The first magnetic member 166 and the second magnetic member 167 repel each other to provide a force to push the sliding seat 12 to slide towards the bottom end of the main rod 11, thereby driving each support leg 13 to unfold to form a support structure of the support stand 1. Specifically, during the folding process of the support leg 13, the first magnetic member 166 is close to the second magnetic member 167, and the first magnetic member 166 and the second magnetic member 167 repel each other to store energy. At this time, the locking mechanism 15 locks the main rod 11, and each support leg 14 remains in the folded state. When in use, the locking mechanism 15 releases the locking of the position of the main rod 11 and the sliding seat 12 in the folded state of each support leg 14, the repulsive force between the magnetic poles of the first magnetic member 166 and the second magnetic member 167 releases energy to push the sliding seat 12 to slide on the main rod 11, thereby driving each support leg 14 to unfold through the connecting rod 15. The repulsive force between the first magnetic member 166 and the second magnetic member 167 through the magnetic force can provide a force for the sliding of the sliding seat 12 on the main rod 11.

[0065] Specifically, the first magnetic member 166 and the second magnetic member 167 are both annular magnetic members; the first magnetic member 166 is sleeved on the main rod 11, and the second magnetic member 167 is installed on the inner wall of the sleeve 13 away from the sliding seat 12. The first magnetic member 166 and the second magnetic member 167 are both annular magnetic members, which can provide stable and sufficient magnetic force. Specifically, the first magnetic member 166 is composed of a plurality of magnets, and the second magnetic member 167 is also composed of a plurality of magnets. The number of magnets in the first magnetic member 166 and the second magnetic member 167 is the same, and the positions of the magnets in the first magnetic member 166 and the second magnetic member 167 are one-to-one. The magnetic pole directions of the magnets in the first magnetic member 166 and the second magnetic member 167 are the same, so that the first magnetic member 166 and the second magnetic member 167 can provide the sliding force of the sliding seat 12 and the main rod 11 through the repulsion force of multiple pairs of magnets.

[0066] As shown in Figures 11 to 15 , the locking mechanism 15 includes a button 151 and a reset member 152. The button 151 is provided with a pressing portion 1511 and a locking portion 1512. The reset member 152 is installed in the sliding seat 12 and abuts against the pressing portion 1511 to push the pressing portion 1511 to reset. When the pressing portion 1511 is pressed, the locking portion 1512 can be separated from the main rod 11 to release the locking state. The sliding seat 12 and the main rod 11 slide, that is, the sliding seat 12 is provided with a cavity 123 for the main rod 11 to pass through. The locking portion 1512 contacts the main rod 11, that is, the locking portion 1512 can extend into the cavity 123 to contact the main rod 11.

[0067] Referring to Figure 14 , the sliding seat 12 includes an outer shell 121 and an inner liner 122. The outer shell 121 is sleeved on the inner liner 122, and the inner liner 122 is sleeved on the main rod 11. The outer shell 121 is provided with a pressing hole 1211 for the pressing portion 1511 to be exposed. The inner liner 122 is provided with a first installation groove 1221 for the button 151 to be installed. The first installation groove 1221 is provided with a locking hole 1222 for the locking portion 1512 to extend out. When the locking mechanism 15 is in the locking state, the locking portion 1512 extends out of the locking hole 1222 to contact the main rod 11 to lock the position of the main rod 11 and the sliding seat 12. The reset member 152 is a second spring, which is installed in the first installation groove 1221 and clamped between the inner liner 122 and the pressing portion 1511.

[0068] Continuing to refer to Figure 14 , the button 151 is provided with a shaft portion 1513. The inner liner 122 is provided with a second installation groove 1223 matched with the shaft portion 1513. When the pressing portion 1511 is pressed, the pressing portion 1511 moves towards the bottom of the first installation groove 1221 with the shaft portion 1513 as the fulcrum, so that the locking portion 1512 moves and separates from the main rod 11.

[0069] In an embodiment, the main rod 11 is provided with a locking slot (not shown in the figure), and the locking part 1512 is clamped into the locking slot when the support foot 13 is in the retracted state.

[0070] In an embodiment, referring to Figure 11 and Figure 12 , at least one support foot 13 is provided with a limiting part 131, which is arranged at the end of the support foot 13 away from the sliding seat 12. When the locking mechanism 15 is in the locked state, the main rod 11 is located between the limiting part 131 and the locking part 1512, and the locking part 1512 abuts against the top end of the main rod 11. Thus, in the locked state, the locking part 1512 abuts against the top end of the main rod 11, and the limiting part 131 is located at the bottom end of the main rod 11 (the limiting part 131 can be in contact with the bottom end of the main rod 11 or have a certain distance therefrom) when the support foot 13 is retracted. That is to say, in this state, the main rod 11 is always located between the limiting part 131 and the locking part 1512, so that the support foot 13 can be kept in the retracted state. In the unlocked state, that is, by the locking mechanism 15, the locking part 1512 no longer abuts against the top end of the main rod 11, so that the main rod 11 can slide under the action of the unfolding mechanism 16 to unfold the support foot 13. It should be understood that when the main rod 11 is arranged as a telescopic rod, the abutment against the top end of the main rod 11 refers to the abutment against the top end of the outermost rod of the telescopic rod.

[0071] In an embodiment, the locking mechanism 15 is arranged in two and symmetrically arranged on the sliding seat 12 in the length direction of the main rod 11. The arrangement of the locking mechanism 15 in two can effectively prevent the unlocking of the locking mechanism 15 caused by accidental touch, and the two symmetrically arranged locking mechanisms 15 are equivalent to two locking parts 1512 acting on the main rod 11, so that the main rod 11 can be more stably locked.
