Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a support leg and tripod. Background Technology

[0002] The existing tripod includes components such as a telescopic rod assembly, a fixed base, support legs, and a support platform. The fixed base is fitted onto the telescopic rod assembly, and the support platform is set at the top of the telescopic rod assembly to support shooting equipment such as cameras and mobile phones. One end of each of the three support legs is rotatably mounted on the fixed base and is connected to the telescopic rod assembly through connecting rods.

[0003] However, the support leg structure of this tripod is only suitable for relatively flat ground or flat tabletops, and each time it is used, it is necessary to open each support leg, pull the telescopic rod assembly, and then fix the shooting equipment on the support platform, which is a rather cumbersome operation. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes a support leg, comprising:

[0006] The support body has one end adapted to be rotatably connected to the pole of the tripod, and the other end is provided with a first clamping arm;

[0007] A self-restoring elastic component is disposed within the support body; and

[0008] A movable component is movably disposed on the support body along the length direction of the support body. One end of the movable component is connected to the self-resetting elastic component, and the other end of the self-resetting elastic component is connected to the inner wall of the support body. The movable component is provided with a second clamping arm. The first clamping arm and the second clamping arm constitute a clamping structure for clamping an object. The self-resetting elastic component is used to provide clamping force and reset the movable component.

[0009] Optionally, the support leg further includes a control element, which is disposed on the support leg body and connected and fixed to the movable element. The control element is used to drive the movable element to move along the length direction of the support leg body under the action of an external force, so as to adjust the relative distance between the first clamping arm and the second clamping arm.

[0010] Optionally, the support body is provided with a slide groove, the self-recovering elastic component is housed in the slide groove, and one end of the movable component is provided with a bent arm that is slidably disposed in the slide groove and connected to the self-recovering elastic component.

[0011] Optionally, the self-recovering elastic component is a tension spring or a tension elastomer.

[0012] Optionally, the control element is a pusher element, which is connected to the movable element by screws. The pusher element is used to manually push the second clamping arm away from the first clamping arm.

[0013] Optionally, the control element is a knob, which is connected to the movable element by bolts. The knob is used to manually push the second clamping arm away from the first clamping arm and to lock or loosen the movable element and the support body when manually rotated.

[0014] Optionally, the control element is a lever, which is connected to the movable element via a pin and a pin seat. The lever is used to drive the second clamping arm away from the first clamping arm when manually pushed and to lock or release the movable element from the support body when manually turned.

[0015] To achieve the above objectives, this utility model also proposes a tripod, comprising:

[0016] Rod; and

[0017] At least three legs are rotatably mounted on the rod body, switching between an extended position and a retracted position, and at least one of the legs is the aforementioned support leg, which includes:

[0018] The support body has one end adapted to be rotatably connected to the pole of the tripod, and the other end is provided with a first clamping arm;

[0019] A self-restoring elastic component is disposed within the support body; and

[0020] A movable component is movably disposed on the support body along the length direction of the support body. One end of the movable component is connected to the self-recovering elastic component, and the other end of the self-recovering elastic component is connected to the inner wall of the support body. The movable component is provided with a second clamping arm, and the first clamping arm and the second clamping arm constitute a clamping structure for clamping an object.

[0021] Optionally, one of the legs is the support leg and the opening angle of the support leg in the unfolded position is greater than the opening angle of the other legs in the unfolded position, and the contact surface formed by the ends of the support leg and the other legs, which is suitable for contacting the table or the ground, is in a horizontal position.

[0022] Optionally, in the stored position, the support leg and the other legs are respectively abutted against the outer periphery of the rod, and the clamping structure of the support leg is arranged opposite to the bottom end face of the rod.

[0023] In the technical solution of this utility model, the support leg includes a support body, a self-resetting elastic component, and a movable component. One end of the support body is adapted to be rotatably connected to the rod of the tripod, and the other end of the support body is provided with a first clamping arm. The self-resetting elastic component is disposed within the support body. The movable component is movably disposed on the support body along its length direction. The movable component is connected to one end of the self-resetting elastic component, and the other end of the self-resetting elastic component is connected to the inner wall of the support body. The movable component is provided with a second clamping arm. The first clamping arm and the second clamping arm constitute a clamping structure for clamping an object. The self-resetting elastic component is used to provide clamping force and to reset the movable component. It can be understood that this utility model improves the support leg structure of the tripod, allowing the tripod to be clamped onto objects that can be clamped by clamping mechanisms, such as boards or shelves on desktops or workbenches. This makes it more applicable to a wider range of scenarios, and in this case, there is no need for cumbersome operation. It is only necessary to fix the shooting equipment on the platform of the tripod and then clamp the support leg of the tripod at the target position (the order of the two operation steps can be interchanged), making it more convenient to use.

[0048] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0051] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0053] This utility model proposes a support leg that can be used as the leg of a tripod or other stand to enable the stand to have a clamping function, or it can be used as a grip for a handheld gimbal to enable the grip to have a clamping function, and the invention is not limited thereto.

[0054] Reference Figures 1 to 10 In some embodiments of this utility model, the support leg 100 is applied to a tripod. The support leg 100 includes a support body 10, a self-restoring elastic component 20, and a movable component 30. One end of the support body 10 is adapted to be rotatably connected to the rod 200 of the tripod, and the other end of the support body 10 is provided with a first clamping arm 11. The self-restoring elastic component 20 is disposed inside the support body 10. The movable component 30 is movably disposed on the support body 10 along the length direction of the support body 10. The movable component 30 is connected to one end of the self-restoring elastic component 20, and the other end of the self-restoring elastic component 20 is connected to the inner wall of the support body 10. The movable component 30 is provided with a second clamping arm 31. The first clamping arm 11 and the second clamping arm 31 constitute a clamping structure for clamping an object. The self-restoring elastic component 20 is used to provide clamping force and reset the movable component 30.

[0055] In this embodiment, the support body 10 can be a sheet structure with an arc-shaped cross section, so as to better fit the outer peripheral wall of the cylindrical rod 200 of the tripod when stored; of course, the support body 10 can also be a cylinder, cuboid or irregular shape, which is not limited here.

[0056] The self-recovering elastic component 20 may be a number of tension springs or other tensile elastic bodies. The tensile elastic body is an elastic element, elastic component or elastic structure made of metal or plastic that can be stretched and self-recovering. Any component, component or structure that can provide clamping force to the clamping structure and restore the movable part 30 to its initial position is acceptable and is not limited here.

[0057] The movable component 30 can be an L-shaped plate structure, with one end of one side movably inserted into the support body 10, and the other side serving as a second clamping arm 31. The corresponding first clamping arm 11 can also be a plate structure of the same or similar size. Alternatively, the movable component 30 can be an assembly structure of a sliding rod and a clamping block. One end of the sliding rod is slidably disposed in the support body 10, and the other end of the sliding rod is connected to the clamping block. The clamping block is located outside the support body 10 and serves as the second clamping arm 31. The corresponding first clamping arm 11 can be a block structure of the same or similar size.

[0058] It is understood that this utility model improves the structure of the tripod's support leg 100, allowing the tripod to be clamped onto objects such as desktops or workbenches or shelves that can be clamped by clamping mechanisms. This makes it applicable to a wider range of scenarios, and in such cases, there is no need for complicated operations. Simply fix the shooting equipment on the tripod platform and then clamp the tripod's support leg 100 at the target position (the order of the two operation steps can be interchanged), making it more convenient to use.

[0059] To further improve ease of use, the main reference is... Figures 5 to 21 In some embodiments, the support leg 100 may further include a control member, which is disposed on the support leg body 10 and connected and fixed to the movable member 30. The control member is used to drive the movable member 30 to move along the length direction of the support leg body 10 under the action of external force, so as to adjust the relative distance between the first clamping arm 11 and the second clamping arm 31.

[0060] In this embodiment, as Figures 18 to 21 As shown, the support body 10 has a groove 10a, and the self-restoring elastic component 20 is housed in the groove 10a. One end of the movable component 30 has a bent arm 32 that is slidably disposed in the groove 10a and connected to the self-restoring elastic component 20. The self-restoring elastic component 20 can be selected as two tension springs, and the ends of the tension springs are engaged with the bent arm 32. Of course, in some other embodiments, a ball bearing rolling structure can also be used, which is not limited here.

[0061] Furthermore, such as Figure 11 As shown, the top wall of the support body 10 may be provided with a clearance channel 10b extending along its length. The control member passes through the clearance channel 10b and is connected and fixed to the movable member 30. It should be noted that by setting the length of the clearance channel 10b, the range of motion of the movable member 30 can be controlled, that is, the size of the clamping space of the clamping structure. In this embodiment, the top wall of the support body 10 may be formed by a separate top shell and serve as an appearance decoration. The shape of the clearance channel 10b should be adapted to the movement trajectory of the control member, and aesthetic treatment should be carried out as much as possible to make the overall design more industrially aesthetic.

[0062] In one embodiment, the main reference is... Figures 5 to 10The control component is a pusher 410. The pusher 410 and the movable component 30 can be connected by screws 411. The pusher 410 is used to drive the second clamping arm 31 away from the first clamping arm 11 when manually pushed.

[0063] In use, the movable part 30 can be pushed out by manually pushing the pusher 410. Of course, in this scenario, the user can also directly pull the second clamping arm 31 to the target position, but this is relatively more strenuous.

[0064] In another embodiment, primarily referring to Figures 11 to 15 The control element is a knob 420, which is connected to the movable part 30 by a bolt 421. The knob 420 is used to manually push the second clamping arm 31 away from the first clamping arm 11 and to lock or loosen the movable part 30 and the support body 10 when manually rotated. An external hex bolt 421 can be used to fix the knob 420 and the movable part 30.

[0065] In use, the second clamping arm 31 of the movable part 30 can be pushed out to the target position by manually pushing the knob 420 first, and then the knob 420 can be turned to lock the movable part 30 and the support body 10, thereby ensuring the reliability of clamping the object. It should be noted that during operation, the knob 420 can be locked at any point in the clearance channel 10b.

[0066] In yet another embodiment, the main reference is... Figures 16 to 21 The control mechanism uses a lever 430, which is connected to the movable part 30 via a pin 431 and a pin seat 432. The lever 430 is used to manually push the second clamping arm 31 away from the first clamping arm 11 and to lock or release the movable part 30 from the support body 10 when manually operated. In this way, while realizing the clamping function, the reliability of the clamped object is effectively ensured.

[0067] In this embodiment, the pin seat 432 can be an external hexagonal pin. The pin is fixed on the movable part 30 and passes through the clearance channel 10b. Both the buckle 430 and the pin are provided with corresponding pin holes. The pin 431 is inserted into the pin holes of the buckle 430 and the pin to install the buckle 430 on the pin. The buckle 430 can be locked at any point in the clearance channel 10b.

[0068] When in use, you can first manually push the lever 430 to push the second clamping arm 31 of the movable part 30 to the target position, and then pull down the lever 430 to lock the movable part 30 and the support body 10, thereby ensuring the reliability of clamping the object.

[0069] This utility model also proposes a tripod, such as Figures 1 to 4As shown, the tripod includes a support leg 100. The specific structure of the support leg 100 is as described in the above embodiment. Since the tripod proposed by this utility model includes all solutions of all embodiments of the support leg 100, it has at least the same technical effects as the support leg 100 described above, which will not be described in detail here.

[0070] Reference Figures 1 to 4 In one embodiment of this utility model, the stand includes a rod 200 and at least three legs, which are rotatably switchable between an extended position and a retracted position on the rod 200, and at least one of the legs is the aforementioned support leg 100. Preferably, to meet the needs of different support heights, the rod 200 in this embodiment can be a telescopic rod assembly.

[0071] In this embodiment, as Figure 3 As shown, only one leg uses the aforementioned support leg 100, and the opening angle of this support leg 100 in the unfolded position is greater than the opening angle of the other legs in the unfolded position. Furthermore, the contact surface formed by the ends of the support leg 100 and the other legs, suitable for contact with a tabletop or ground, is in a horizontal position. This accommodates common usage scenarios such as flat terrain and level tabletops, helping to ensure the stability of the support.

[0072] To make the tripod smaller in overall size after being folded up, making it more convenient for users to carry and store, refer to Figure 1 and Figure 2 In some embodiments, the tripod can be configured such that when in the stowed position, the support leg 100 and the other legs are respectively attached to the outer periphery of the rod body 200, and the clamping structure of the support leg 100 is arranged opposite to the bottom end face of the rod body 200.

[0073] To meet the usage needs of users in more scenarios, in some embodiments, the tripod also includes a support platform 300. The support platform 300 is set at the top of the rod 200 and can be configured with clips and / or magnetic structures to more conveniently fix different types of objects. The support platform 300 can be connected to the rod 200 through a connecting plate or rod. The support platform 300 can rotate 360° relative to the connecting plate or rod, and the connecting plate or rod can perform pitching and 360° rotation relative to the rod 200.

[0074] In addition, a removable Bluetooth remote control 400 can be installed on the fixed base of the pole 200. Correspondingly, the tripod can be equipped with control circuit, Bluetooth module and electric drive mechanism, etc. Users can control the movement of the tripod through Bluetooth remote control 400, thereby meeting the usage needs of more scenarios and providing a better user experience.

[0075] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
