[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] Please see Figures 1-6 This utility model embodiment provides a double-locking gimbal structure, including: a first connector 10, the first connector 10 including a first clamping part 101 and a second clamping part 102 movably connected, forming a clamping space 103 between the first clamping part 101 and the second clamping part 102; a clamping locking structure 20, the first connector 10 being movably connected to the clamping locking structure 20, the clamping locking structure 20 being used to restrict the relative movement between the first clamping part 101 and the second clamping part 102; a second connector 30, the first connector 10 being movably connected to the second connector 30; and a first angle locking structure 40, the first connector 10 and the second connector 30 being movably connected to the first angle locking structure 40, the first angle locking structure 40 being used to restrict the relative movement between the first connector 10 and the second connector 30.

[0043] In this utility model, the first clamping part 101 and the second clamping part 102 of the first connecting member 10 form a clamping structure. A clamping locking structure 20 is provided on the first connecting member 10 to achieve clamping and locking. The clamping structure formed by the first connecting member 10 can rotate relative to the second connecting member 30, so the angle of the clamping structure is adjustable. A first angle locking structure 40 is provided to lock after the angle is adjusted. Furthermore, both the clamping locking structure 20 and the first angle locking structure 40 can be integrated on the first connecting member 10, making the overall structure more compact.

[0044] In this embodiment of the utility model, the double-locking gimbal structure further includes a third connecting member 50, the second connecting member 30 and the third connecting member 50 are movably connected, and the third connecting member 50 is provided with a bayonet 60; the double-locking gimbal structure further includes a second angle locking structure 70, the second connecting member 30 and the third connecting member 50 are both movably connected to the second angle locking structure 70, and the second angle locking structure 70 is used to restrict the relative movement between the second connecting member 30 and the third connecting member 50.

[0045] When this utility model is in use, a connecting object, such as a camera, photographic light, probe, or other device, can be clamped by the first clamping part 101 and the second clamping part 102, and another connecting object, such as a microphone, flash, or other device, can be snapped into the bayonet 60 position on the third connecting member 50.

[0046] Thus, when the first angle locking structure 40 is not locked, one connected object can move relative to the second connected object 30 along with the first connected member 10, or another connected object can move relative to the first connected member 10 along with the third connected member 50 and the second connected member 30; when the second angle locking structure 70 is not locked, another connected object can move relative to the second connected member 30 along with the third connected member 50, or one connected object can move relative to the third connected member 50 along with the first connected member 10 and the second connected member 30; thus, one connected object has two degrees of freedom relative to another connected object.

[0047] In this embodiment of the utility model, the first connecting member 10 or the second connecting member 30 is rotatably connected, and the second connecting member 30 is rotatably connected to the third connecting member 50; the first connecting member 10 or the second connecting member 30 rotates around the first central axis B1, and the second connecting member 30 and the third connecting member 50 rotate around the second central axis B2; there is an included angle between the first central axis B1 and the second central axis B2.

[0048] For example, referring to 6, the first central axis B1 and the second central axis B2 are set perpendicular to each other, and the angle between the first central axis B1 and the second central axis B2 is 90°. Of course, in some other application scenarios, the angle between the first central axis B1 and the second central axis B2 is other angles, such as 60°, 70°, 80°, 89°, 91°, 110° or 120°, etc. The angle between the first central axis B1 and the second central axis B2 is determined according to the actual application scenario and is not limited.

[0049] Thus, when the first angle locking structure 40 is not locked, one connected object can move relative to the second connected object 30 around the first central axis B1, following the first connected member 10; or another connected object can move relative to the first connected member 10 around the first central axis B1, following the third connected member 50 and the second connected member 30. When the second angle locking structure 70 is not locked, another connected object can move relative to the second connected member 30 around the second central axis B2, following the third connected member 50; or one connected object can move relative to the third connected member 50 around the second central axis B2, following the first connected member 10 and the second connected member 30. Thus, one connected object can rotate in two directions relative to another connected object around the first central axis B1 or the second central axis B2.

[0050] In this embodiment of the present invention, the first clamping part 101 and the second clamping part 102 are nested together. The first clamping part 101 has a first clamping end 1011 extending outward, and the second clamping part 102 has a second clamping end 1021 extending outward. The first clamping part 101 and the second clamping part 102 slide relative to each other to adjust the distance between the first clamping end 1011 and the second clamping end 1021.

[0051] It should be noted that the nested arrangement of the first clamping part 101 and the second clamping part 102 means that: the first clamping part 101 is fitted outside the second clamping part 102, in which case the second clamping part 102 guides the movement of the first clamping part 101; or the second clamping part 102 is fitted outside the first clamping part 101, in which case the first clamping part 101 guides the movement of the second clamping part 102. Because the first clamping part 101 and the second clamping part 102 are nested together, the structure of the first connecting member 10 is more compact.

[0052] For example, see Figure 4 Both the first clamping part 101 and the second clamping part 102 are T-shaped and are coaxially arranged. The first clamping part 101 and the second clamping part 102 slide relative to each other axially to adjust the axial distance between the first clamping end 1011 and the second clamping end 1021. In use, the connecting object is clamped between the first clamping end 1011 and the second clamping end 1021. That is, the clamping space 103 formed between the first clamping part 101 and the second clamping part 102 is the space between the first clamping end 1011 and the second clamping end 1021.

[0053] In this embodiment of the utility model, the first clamping part 101 is a sleeve structure, and the second clamping part 102 is a shaft structure. The first clamping part 101 is sleeved on the outside of the second clamping part 102. The clamping and locking structure 20 includes a clamping and locking member 201, which is sleeved on the outside of the second clamping part and is threadedly connected to the second clamping part.

[0054] For example, see Figure 4 The clamping and locking member 201 is a locking nut, and the clamping and locking member 201 has a threaded hole; the first clamping part 101 has a first connecting end 1012, the first clamping end 1011 is disposed at one end of the first clamping part 101, and the first connecting end 1012 is disposed at the other end of the first clamping part 101; the second clamping part 102 has a second connecting end 1022, the second clamping end 1021 is disposed at one end of the second clamping part 102, and the second connecting end 1022 is disposed at the other end of the second clamping part 102; the second connecting end 1022 of the second clamping part 102 is provided with a thread, and the clamping and locking member 201 is threadedly connected to the second connecting end 1022 of the second clamping part 102.

[0055] In use, after placing the object to be connected into the space between the first clamping end 1011 and the second clamping end 1021, rotate the clamping locking member 201 until the clamping locking member 201 abuts against the second connecting end 1022 of the first clamping part 101 to lock the first clamping part 101 and the second clamping part 102.

[0056] In this embodiment of the utility model, the first angle locking structure 40 includes a first angle locking member 401. The first angle locking member 401 drives the first connecting member 10 and the second connecting member 30 to abut against each other to restrict their relative movement, or the first angle locking member 401 abuts against both the first connecting member 10 and the second connecting member 30 to restrict their relative movement.

[0057] In this embodiment of the utility model, the second connecting member 30 is sleeved outside the first connecting member 10 to form a rotatable connection; the first angle locking member 401 is sleeved outside the first connecting member 10, and the first angle locking member 401 and the first connecting member 10 are threadedly connected; by rotating the first angle locking member 401, the first connecting member 10 and the second connecting member 30 are driven to abut against each other to restrict the relative rotation of the two.

[0058] For example, see Figure 4 The first angle locking member 401 is a locking nut. The first angle locking member 401 has a threaded hole. The first clamping part 101 is provided with a threaded part 1013 that is threadedly connected to the first angle locking member 401. The second connecting member 30 is provided with a mounting hole that is rotatably connected to the first connecting member 10. The second connecting member 30 can be supported on the first end of the first clamping part 101.

[0059] In use, loosen the first angle locking member 401, and the first connecting member 10 and the second connecting member 30 can rotate relative to each other. The second connecting member 30 rotates relative to the first connecting member 10, or the first connecting member 10 rotates relative to the second connecting member 30. After the relative rotation between the first connecting member 10 and the second connecting member 30 is completed, tighten the first angle locking member 401. The first angle locking member 401 and the second connecting member 30 abut against each other, and the second connecting member 30 and the first connecting member 10 abut against each other, thereby achieving locking.

[0060] In this embodiment of the present invention, the first angle locking structure 40 further includes an anti-loosening member 402, which is sleeved on the outside of the first connecting member 10. The anti-loosening member 402 moves along the axial direction of the first connecting member 10 and is disposed between the first angle locking member 401 and the second connecting member 30.

[0061] For example, see Figure 5 The first clamping part 101 is provided with an anti-rotation part 1014. A threaded part 1013 and an anti-rotation part 1014 are sequentially arranged along the circumferential direction of the first clamping part 101. The anti-loosening member 402 is an anti-loosening washer. The anti-loosening member 402 is provided with a first anti-rotation hole 403. The anti-rotation part 1014 and the first anti-rotation hole 403 cooperate with each other to form an anti-rotation structure, so that the anti-loosening member 402 can move along the axial direction of the first connecting member 10. The first clamping part 101 can also be threadedly connected to the first angle locking member 401 through its threaded part 1013.

[0062] The anti-rotation hole can be a D-shaped hole, a waist-shaped hole, an oblong hole, or a square hole.

[0063] After the first angle locking member 401 is locked, when the second connecting member 30 moves or shakes, since the anti-loosening member 402 is set between the first angle locking member 401 and the second connecting member 30, the anti-loosening member 402 separates the first angle locking member 401 and the second connecting member 30, and the anti-loosening member 402 moves along the axial direction of the first connecting member 10, the anti-loosening member 402 does not rotate, and the second connecting member 30 has difficulty driving the first angle locking member 401 to rotate, thereby improving the stability of the first angle locking member 401.

[0064] In this embodiment of the utility model, the second angle locking structure 70 includes a second angle locking member 701. The second angle locking member 701 drives the second connecting member 30 and the third connecting member 50 to abut against each other to restrict their relative movement, or the second angle locking member 701 abuts against both the second connecting member 30 and the third connecting member 50 to restrict their relative movement.

[0065] In this embodiment of the utility model, the second connecting member 30 and / or the third connecting member 50 are provided with a connecting hole 80, and a rotating shaft 90 passes through the connecting hole 80; the second angle locking member 701 is a conical sleeve structure with one end larger than the other end. The second angle locking member 701 is inserted into the connecting hole 80 and sleeved on the outside of the rotating shaft 90. The second angle locking member 701 is movably connected to the rotating shaft 90. The second angle locking member 701 abuts against both the second connecting member 30 and the third connecting member 50 to restrict their relative rotation.

[0066] For example, see Figure 4 as well as Figure 5 Both the second connecting member 30 and the third connecting member 50 are provided with connecting holes 80. The second connecting member 30 and the third connecting member 50 are rotatably connected to the rotating shaft 90 through their connecting holes 80. The second angle locking member 701 has an extension 7011. The second connecting member 30 is provided with a second anti-rotation hole 100 that cooperates with the extension 7011. The second angle locking member 701 moves along the axial direction of the rotating shaft 90 through the cooperation of its extension 7011 and the second anti-rotation hole 100. That is, the second angle locking member 701 moves along the axial direction of the second central shaft B2.

[0067] In use, the user pushes the second angle locking member 701 into at least one connecting hole 80 along the axial direction of the second central axis B2 until the second angle locking member 701 simultaneously abuts against the second connecting member 30 and the third connecting member 50 to achieve locking.

[0068] Furthermore, the second angle locking structure 70 includes a knob 702 and / or a locking bolt 703. The knob 702 or the locking bolt 703 is used to push the second angle locking member 701 to move axially along the direction of the second central axis B2. The rotating shaft 90 has a threaded hole inside. The knob 702 or the locking bolt 703 is inserted into the rotating shaft 90 and threadedly connected to the rotating shaft 90. The knob 702 or the locking bolt 703 is used to lock the second angle locking member 701.

[0069] Continue reading Figure 4 Both the second connector 30 and the third connector 50 are U-shaped. The two sides of the second connector 30 and the third connector 50 are rotatably connected. The two rotatably connected positions of the second connector 30 and the third connector 50 are provided with a second angle locking structure 70.

[0070] The above provides a detailed description of a double-locking gimbal structure disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the double-locking gimbal structure and its core idea. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
