[0009] The locking structure can lock the multiple support legs to retract them, and can unlock each support leg under external pressure to allow it to spring open.

[0010] In some embodiments, the locking structure includes a mounting base, an elastic element, and a button. The mounting base is connected to the end of the rod and is rotatably connected to the connecting rod. The button is slidably disposed relative to the mounting base and locked to the support foot. The two ends of the elastic element abut against the button and the mounting base, respectively.

[0011] In some embodiments, one of the mounting base or the button is provided with a mounting post, and the other is provided with a through groove. The mounting post is slidably disposed in the through groove, and the elastic element is sleeved on the outside of the mounting post.

[0012] In some embodiments, the mounting base is provided with the mounting post;

[0013] The button is provided with the through groove, which includes a first section and a second section. The first section is close to the mounting base, and the inner diameter of the first section is smaller than the inner diameter of the second section.

[0014] The locking structure also includes a limiting screw, which is threadedly connected to the mounting post, and the nut of the limiting screw is located inside the second section. The nut is used to limit the sliding of the button.

[0015] In some embodiments, the mounting base is provided with a mounting groove, and a portion of the mounting post is located within the mounting groove, the mounting groove being used to accommodate the elastic member in a compressed state.

[0022] In summary, the support bracket provided by this utility model has the following technical effects:

[0023] By setting a locking structure, the support legs can be locked to achieve retraction. When the support legs need to be extended, the locking structure receives external force and unlocks the support legs. Since the support legs are rotatably equipped with connecting rods, and the connecting rods are rotatably set in the locking structure, the connecting rods are driven by the elastic force of the torsion spring. The connecting rods rotate relative to the locking structure and then open. The extension of the connecting rods causes the sliding sleeves on the rods to slide, thereby causing the support legs to extend. In this way, multiple support legs can be quickly extended with just a press, which is convenient for users. When the support legs need to be retracted, the sliding sleeves are driven to slide away from the locking structure. When the free end of the support leg approaches the locking structure, it is locked. Attached Figure Description

Detailed Implementation

[0036] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0037] Please see Figures 1 to 11 The support bracket 100 provided in this embodiment of the utility model includes a rod 10, a sliding sleeve 20, a locking structure 30, a support structure 40, and multiple torsion springs 50. Figure 1 and Figure 2 This is a diagram showing the unfolded state. Figures 3 to 7 This is a diagram illustrating the collapsed state.

[0038] The rod 10 serves as a support base, for example, to support electronic devices such as mobile phones and cameras. A sliding sleeve 20 is slidably fitted over the rod 10. A locking structure 30 is located at one end of the rod 10. The support structure 40 includes multiple support feet 41 and multiple connecting rods 42. One end of each support foot 41 is rotatably connected to the sliding sleeve 20. The multiple connecting rods 42 and multiple support feet 41 are arranged in a one-to-one correspondence. One end of each connecting rod 42 is rotatably connected to the support foot 41, and the other end is rotatably connected to the locking structure 30 via a rotating shaft 37. Multiple torsion springs 50 and multiple rotating shafts 37 are arranged in a one-to-one correspondence and fitted onto the rotating shafts 37, used to apply elastic force to the connecting rods 42. The locking structure 30 can lock the multiple support feet 41 to retract them, and can unlock each support foot 41 under external pressure to spring it open.

[0039] The aforementioned support leg 100, by setting a locking structure 30, can lock the support leg 41 to achieve folding. When the support leg 41 needs to be unfolded, the locking structure 30 receives external force and unlocks the support leg 41. Since the support leg 41 is rotatably mounted with a connecting rod 42, and the connecting rod 42 is rotatably mounted with the locking structure 30, the connecting rod 42 is subjected to the elastic driving force of the torsion spring 50. After the connecting rod 42 rotates relative to the locking structure 30, it opens. The unfolding of the connecting rod 42 causes the sliding sleeve 20 to slide on the rod body 10, thereby causing the support leg 41 to unfold. In this way, multiple support legs 4 can be quickly unfolded by simply pressing, which is convenient for the user. When the support leg 41 needs to be folded, the sliding sleeve 20 is driven to slide away from the locking structure 30. When the free end of the support leg 41 approaches the locking structure 30, it can be locked.

[0040] The torsion spring 50 can be a conventional torsion spring, having a helical cylindrical main body and torsion arms located at both ends of the main body. The main body is sleeved on the rotating shaft, with one end of the torsion arm fixedly positioned, and the other end of the torsion arm abutting against the connecting rod 42, specifically against the inner wall of the connecting rod 42. When the connecting rod 42 is in the retracted state, the torsion arm is compressed and constantly provides an elastic driving force to open the connecting rod 42. Therefore, when the support frame 41 is unlocked, the torsion spring 50 can apply an elastic driving force to the connecting rod 42 through its torsion arm. Under the action of the elastic driving force, the connecting rod 42 can rotate and open relative to the locking structure 30.

[0041] In this embodiment, the support leg 100 can be a tripod, a quadrupole, or a support leg 100 with a greater number of support legs 41, and is not limited thereto.

[0042] Furthermore, the rod 10 can be an independent rod-shaped structure, such as a circular tube or a square tube, or it can include multiple telescopic rods 10 that are slidably connected to each other, so that the rod 10 can be adjusted to different support heights. Specifically, in this embodiment, the rod 10 is a telescopic rod, including at least one outer rod and one inner rod. The outer rod is telescopically fitted around the outer periphery of the inner rod to adjust different support heights and improve the practicality of the product.

[0043] When the support foot 41 is opened, the connecting rod 42 is driven to unfold under the elastic force of the torsion spring 50. The unfolding of the connecting rod 42 also drives the sliding sleeve 20 to move closer to the locking structure 30, thereby driving the support foot 41, which is rotatably set on the sliding sleeve 20, to unfold. When the support foot 41 is retracted, the sliding sleeve 20 can be pulled away from the locking structure 30 by hand.

[0044] Understandably, in order to facilitate the movement of the sliding sleeve 20 driven by the hand, the sliding sleeve 20 has a certain extension length along the axial direction of the rod 10, so that it can have sufficient contact area with the hand, facilitate the hand's closing operation, and have a greater connection strength with the rod 10.

[0045] Furthermore, in order to ensure the uniformity of appearance when folded, the sliding sleeve 20 can be provided with two different outer diameters. When the support leg 41 and the connecting rod 42 are in the folded state, they can fit into the smaller outer diameter section, so that the entire support leg 100 can have a uniform outer diameter when folded.

[0046] Please see Figure 1 , Figure 2 , Figures 5 to 11 This is a schematic diagram of the locking structure 30 in this embodiment. The locking structure 30 includes a mounting base 31, an elastic element 32, and a button 33. The mounting base 31 is connected to the end of the rod 10 and is rotatably connected to the connecting rod 42. The button 33 is slidably disposed relative to the mounting base 31 and can be locked with the support foot 41. The two ends of the elastic element 32 abut against the button 33 and the mounting base 31, respectively. Thus, when the support foot 41 is unfolded, the button 33 is pressed by hand. At this time, the button 33 compresses the elastic element 32 and disengages from the support foot 41. After the support foot 41 and the button 33 are disengaged, the connecting rod 42 is subjected to the elastic force of the torsion spring 50. The torsion spring 50 springs the connecting rod 42 open. The unfolding movement of the connecting rod 42 drives the unfolding movement of the support foot 41, thereby realizing the opening of the support foot 41. At the same time, under the action of the elastic force of the elastic element 32, the button 33 slides back to its original position relative to the mounting base 31, preparing for the next retraction and locking of the support foot 41.

[0047] Furthermore, since the button 33 needs to slide relative to the mounting base 31 along the axial direction of the rod 10 to compress the elastic member 32 in this direction of movement, one of the mounting base 31 or the button 33 is provided with a mounting post 312 and the other is provided with a through groove 331. The mounting post 312 is slidably disposed in the through groove 331, and the elastic member 32 is sleeved on the outside of the mounting post 312. In this way, the mounting post 312 can be used to position the installation of the elastic member 32 and guide the extension and retraction of the elastic member 32 so that the elastic member 32 can extend and retract along the axial direction of the rod 10.

[0048] Specifically, in this embodiment, when the mounting post 312 and the through slot 331 are set, the mounting post 312 is set on the mounting base 31, and the button 33 is provided with the through slot 331. In this way, the way of setting the slot in the button 33 makes the button 33 lightweight and easy to slide; or in another embodiment, the mounting post 312 can be provided on the button 33 and the through slot 331 can be provided on the mounting base 31 as needed, which is not limited here.

[0049] Understandably, since button 33 needs to slide relative to mounting base 31, to prevent button 33 from becoming loose relative to mounting base 31 when elastic force is applied to button 33 by elastic member 32, mounting base 31 needs to be provided with a limiting structure to restrict the sliding distance of button 33. Specifically, in this embodiment, when setting the limiting structure, please refer to... Figures 6 to 8 The through-groove 331 includes a first section 3311 and a second section 3312 with different outer diameters. The first section 3311 is close to the mounting base 31, and the second section 3312 is far away from the mounting base 31. The inner diameter of the first section 3311 is smaller than that of the second section. The first section 3311 and the mounting post 312 are clearance-fitted to slide with the mounting post 312. The locking structure 30 also includes a limiting screw 36. The limiting screw 36 is threadedly connected to the mounting post 312, and the nut 361 of the limiting screw 36 is located in the second section 3312. The nut 361 is used to limit the sliding of the button 33. In this way, the movement of the button 33 is limited by the nut 361 of the limiting screw 36 to prevent it from loosening relative to the mounting base 31. In other embodiments, a limiting block can be provided on the inner wall of the mounting base 31 and extended towards the center. When the button 33 moves to contact the limiting block under the elastic force of the elastic member 32, it stops moving, which can also achieve the limiting effect of the button 33.

[0050] Furthermore, when the entire support leg 100 is in the retracted state, in order to shorten the length of the entire support leg 100, the mounting base 31 is provided with a mounting groove 313, and part of the mounting post 312 is provided in the mounting groove 313. The mounting groove 313 is used to accommodate the elastic element 32 in a compressed state. Thus, through the setting of the mounting groove 313, when the button 33 locks the support leg 41, the elastic element 32 is in a compressed state and is compressed in the mounting groove 313, so that the button 33 and the mounting base 31 can be as close as possible, thereby shortening the length of the entire support leg 100 along the axial direction of the rod 10.

[0051] Please see Figures 7 to 11 In one embodiment of this utility model, in order to guide the telescopic movement of the button 33, one of the mounting base 31 or the button 33 is provided with a guide groove 332, and the other is provided with a guide post 314. The guide post 314 is slidably disposed in the guide groove 332. In this way, the movement of the button 33 can be guided by the guide post 314 and the guide groove 332 to ensure the stability of the movement of the button 33 in the straight line direction.

[0052] Understandably, multiple guide posts 314 and multiple guide grooves 332 can be provided in the mounting base 31 or the button 33. One guide post 314 is slidably disposed in one guide groove 332. By setting multiple guide posts 314 and multiple guide grooves 332, the sliding movement of the button 33 can be further limited.

[0053] Furthermore, when the mounting base 31 is made of plastic, due to its certain thickness, in order to facilitate the injection molding of the entire mounting base 31, the mounting base 31 includes a mounting part 315 and a connecting part 316. The mounting part 315 forms an installation space, the connecting part 316 is installed in the installation space, and is provided with the aforementioned mounting post 312 and guide post 314, and the button 33 slides in the installation space.

[0054] When connecting the mounting part 315 and the connecting part 316, the limiting screw 36 passes through the mounting post 312 to connect the mounting part 315 and the connecting part 316 into one unit.

[0055] Please see Figures 5 to 7 as well as Figure 10 , Figure 11 In one embodiment of this utility model, when the support foot 41 is locked and unlocked by the locking structure 30, one of the free ends of the locking structure 30 or the support foot 41 is provided with a slot 411, and the other is provided with a block 34. The block 34 is engaged in the slot 411 to lock the support foot 41 by the locking structure 30. After pressing the locking structure 30, the block 34 disengages from the slot 411 to unlock both.

[0056] Specifically, in this embodiment, the free end of the support leg 41 is provided with a slot 411, and the locking structure 30 is provided with a block 34, specifically the button 33 is provided with a block 34. In another embodiment, the slot 411 can be provided on the button 33 and the block 34 can be provided on the support leg.

[0057] In this embodiment, when a locking block 34 is provided on the locking structure 30, the locking structure 30 is provided with an avoidance groove 35, and the groove wall of the avoidance groove 35 is provided with a locking block 34, that is, the button 33 is provided with an avoidance groove 35; the support leg 41 includes a main body 413 and a locking head 412 provided at the free end of the main body 413. The locking head 412 is provided with a slot 411. When the support leg 41 is in a locked state relative to the locking structure 30, the locking head 412 is provided in the avoidance groove 35. By providing the avoidance groove 35, the locking head 412 on the support leg 41 can be received so that the locking block 34 can be inserted into the slot 411 of the locking head 412. In this way, the overall uniformity of the entire support leg 100 when it is folded up is ensured.

[0058] To ensure the uniformity of the entire support frame 100 when it is folded, the locking structure 30 is provided with a clearance notch 311. Specifically, the mounting base 31 is provided with a clearance notch 311, and one end of the connecting rod 42 is rotatably disposed at the clearance notch 311 and faces the button 33. The clearance notch 311 extends to the side of the mounting base 31. By setting the clearance notch 311, one end of the connecting rod 42 and the rotating shaft 37 can be disposed in the clearance notch 311. When the support frame 100 is in the folded state, the connecting rod 42 can be as close as possible to the outer wall of the rod body 10, and the support foot 41 can be as close as possible to the outer wall of the rod body 10, thereby ensuring the uniformity of the appearance structure when folded.

[0059] Understandably, corresponding to the clearance notch 311 on the mounting base 31, and in the retracted state, the connecting rod 42 can fit against the outer wall of the rod body 10. The connecting rod 42 includes a rotating part 421 and an extension part 422 set at approximately a 90-degree angle. The rotating part 421 and the rotating shaft 37 are rotatably arranged. In the retracted state, the extension part 422 fits against the outer wall of the rod body 10.

[0060] The above-mentioned support leg 100 is used as follows: When the support leg 41 needs to be opened, the hand presses the button 33, causing the locking head 412 on the support leg 41 to disengage from the latch 34 on the button 33. Under the elastic force of the torsion spring 50, the connecting rod 42 is driven to rotate. The rotation of the connecting rod 42 drives the support leg 41 to rotate relative to the mounting base 31 and open. At the same time, it drives the sliding sleeve 20 to move closer to the locking structure 30. When the support leg 100 needs to be closed, the hand pulls the sliding sleeve 20 to move away from the locking structure 30, which drives the support leg 41 and the connecting rod 42 to rotate respectively, so that the locking head 412 on the support leg 41 locks on the latch 34 of the button 33, thereby realizing the closure.

[0061] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
