Description

Technical Field

[0002] Prior art, such as Chinese utility model patent document with publication number CN219828379U, discloses a quick-release head and a photographic tripod, wherein the quick-release head comprises: a base with a slide groove on the top; a quick-release plate that can slide into the slide groove from an opening on one side of the slide groove; a locking mechanism for locking the quick-release plate; the locking mechanism comprises: an elastic member that is arranged between the locking member and the base and forces the locking member to be located in the locking position; the locking member comprises a locking portion and an operating portion, the locking portion having a locking position for locking the quick-release plate and an unlocking position for disengaging the quick-release plate; when the operating portion is pressed, the locking member overcomes the elasticity of the elastic member and switches from the locking position to the unlocking position.

[0003] Based on the above, in the prior art, the quick-release plate is assembled into the slide slot by plugging, and then the front and rear positions of the quick-release plate are constrained under the locking action of the locking mechanism to achieve the assembly of the quick-release plate. The technical problem with this assembly method is that in order to ensure that the quick-release plate and the slide slot are plugged in more smoothly, the quick-release plate and the slide slot are not perfectly matched during the design, and the slide slot reserves a larger space to allow the quick-release plate to be better plugged in and assembled. This reserved space will cause the quick-release plate to move up and down relative to the base, which is prone to shaking during use, and needs further improvement. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1-Figure 6 A pan / tilt structure with quick disassembly and good stability includes a pan / tilt seat 10 and a quick-release plate 20, the pan / tilt seat 10 is provided with a cavity 110 for plugging with the quick-release plate 20, the front side of the cavity 110 is opened, the left and right sides of the cavity 110 are provided with first limiting grooves 120, the left and right sides of the quick-release plate 20 are provided with limiting ribs 210 that can be plugged into the first limiting grooves 120, the cavity 110 is provided with an elastic element 130 that applies an upward force to the quick-release plate 20, and the cavity 110 is provided with a limiting component 30 for limiting the quick-release plate 20 from detaching from the cavity 110.

[0022] The quick-release plate 20 is plugged into the pan-tilt base 10 for assembly. During the assembly process, the elastic element can exert an upward force on the quick-release plate, so that the quick-release plate after plugging and assembly is pressed tightly by the elastic element to prevent it from shaking. At the same time, when the assembly is completed, the limit assembly 30 limits the quick-release plate 20 so that it cannot be separated from the cavity 110.

[0023] See also Figure 4 and Figure 5 In the present invention, two groups of limit assemblies 30 are provided and are respectively provided on opposite sides. When the quick-release plate 20 is operated, unlocking is achieved by pressing the limit assemblies 30 on both sides.

[0024] See also Figure 4 The pan-tilt seat 10 is provided with a first installation cavity 101, a connecting hole 105 communicating with the receiving cavity 110 is provided above the first installation cavity 101, a moving seat 300 is provided in the first installation cavity 101, a limiting protrusion 301 is provided on the moving seat 300, the limiting protrusion 301 passes through the connecting hole 105 and extends into the receiving cavity 110, and a first elastic member 310 for applying an upward force to the moving seat 300 is provided in the first installation cavity 101;

[0025] The lower end surface of the quick-release plate 20 is provided with a second limiting groove 200 which is plugged and matched with the limiting protrusion 301;

[0026] A second installation cavity 102 is disposed on the pan-tilt seat 10 outside the first installation cavity 101 , and a pressing member 410 is disposed in the second installation cavity 102 for driving the movable seat 300 to move downward.

[0027] See also Figure 2 A guide ramp 303 is provided on the front side of the upper end surface of the limiting protrusion 301 , and the front end of the guide ramp 303 is flush with the bottom surface of the cavity 110 .

[0028] During assembly, the quick-release plate 20 and the pan-tilt seat 10 are plugged and assembled. When the rear end of the quick-release plate 20 contacts the guide ramp 303, the quick-release plate 20 will squeeze the limiting protrusion 301 to move it downward. When it moves downward, it will compress the first elastic member 310 until the limiting protrusion 301 coincides with the second limiting groove 200. Under the action of the first elastic member 310, the limiting protrusion 301 is inserted into the second limiting groove 200 to constrain the front and rear position of the quick-release plate 20, thereby achieving position limitation so that it cannot be detached from the cavity 110.

[0029] See also Figure 4 and Figure 5 A driven inclined surface 302 is disposed on the side of the moving seat 300 facing the pressing member 410 , and an active inclined surface 411 is disposed on the side of the moving seat 300 facing the driven inclined surface 302 . The active inclined surface 411 can be fitted with the driven inclined surface 302 .

[0030] When the pressing member 410 is moved from the inside by external force, the active inclined surface 411 cooperates with the driven inclined surface 302 to drive the movable seat 300 to move downward, so that the limiting protrusion 301 is disengaged from the second limiting groove 200 to complete the unlocking. Without the constraint of the limiting protrusion 301, the quick-release plate 20 can be disengaged from the cavity 110 to achieve disassembly.

[0031] See also Figure 6 The second mounting cavity 102 includes a first mounting groove 104 disposed in the pan-tilt seat 10, an opening 103 penetrating the pan-tilt seat 10 is disposed outside the first mounting groove 104, a pressing protrusion 420 is disposed on the outer wall surface of the pressing member 410, and the pressing protrusion 420 passes through the opening 103 and extends to the outside of the pan-tilt seat 10;

[0032] A second elastic member 430 is connected between the pressing member 410 and the second mounting cavity 102 .

[0033] The function of the second elastic member 430 is to apply an outward force to the pressing member 410. When the user presses the pressing bump 420, the pressing member 410 is driven inward to drive the movable seat 300 downward, so that the second elastic member 430 is compressed. When the pressing member 410 is released, the pressing member 410 moves outward under the action of the second elastic member 430 to reset.

[0034] In the present invention, the first elastic member 310 and the second elastic member 430 are springs.

[0035] See also Figure 2 A groove 131 is provided on the bottom surface of the cavity 110, a deformable member 132 is provided in the groove 131, a protrusion 133 is provided on the deformable member 132, the deformable member 132 is connected to the pan-tilt seat 10, and the protrusion 133 is in contact with the lower end surface of the quick-release plate 20.

[0036] Furthermore, a guide slope 134 is provided on the front side of the protrusion 133 .

[0037] When the quick-release plate 20 and the pan-tilt mount 10 are plugged in and assembled, the quick-release plate 20 contacts the guide slope 134 on the front side of the protrusion 133, which squeezes the protrusion 133 to deform the deformable member 132 downward until the quick-release plate 20 and the pan-tilt mount 10 are fully plugged in. Then, the protrusion 133, under the action of the deformable member 132, pushes the quick-release plate 20 upward.
