[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] I. Working principle of the present utility model:

[0032] The dual - buckle - locked multi - angle connector of the present utility model mainly consists of a first connector, a second connector and a limit button. The first connector is installed on the upper part of the second connector and fixed by the limit button. One end of the first connector and the second connector are respectively provided with insertion parts for connecting other pipe fittings. The second connector and the protrusion are provided with through - holes, and long screws are arranged inside the through - holes. The first connector rotates around the long screws to achieve multi - angle adjustment;

[0033] One end of the first connector away from the insertion part is provided with a protrusion. The second connector is provided with an assembly groove that penetrates the second connector, and the protrusion is located in the assembly groove. One side of the protrusion is a smooth plate - like structure, and the other side is provided with a plurality of tooth - shaped protrusions that are circumferentially distributed and intermittently arranged.

[0034] The limit button is installed on the second connector and includes a pressing plate, a link and a dual - buckle body that are connected in sequence. One side of the second connector is provided with a card slot for installing the limit button, and a detachable spring is arranged at the bottom of the card slot to provide a reset force for the limit button; The second connector is provided with a through - hole that cooperates with the dual - buckle body, and the cross - sectional shapes of the dual - buckle body and the through - hole are the same as the cross - sectional shapes of two adjacent tooth - shaped protrusions.

[0035] 1.1 Angle adjustment principle

[0036] As shown in Figures 5-6 , the first connecting member 1 is installed in the assembly groove 201 of the second connecting member 2 through the protruding portion 101. When the angle needs to be adjusted, press the pressing plate 301 of the limit button 3 to separate the double buckle body 303 from the tooth-shaped protrusion 1011 of the protruding portion 101. At this time, the first connecting member 1 can rotate freely around the long screw. After adjusting to the required angle, release the pressing plate 301, and the spring 204 pushes the double buckle body 303 to be stuck between the new tooth-shaped protrusions 1011 to achieve angle locking.

[0037] 1.2 Locking principle

[0038] As shown in Figure 6 , in the normal state, the spring 204 is in a compressed state, pressing the double buckle body 303 of the limit button 3 tightly between the tooth-shaped protrusions 1011 of the protruding portion 101. Since one side of the protruding portion 101 is a smooth plate-like structure and the other side is a tooth-shaped protrusion 1011, the double buckle body 303 can only enter from one side of the tooth-shaped protrusion 1011 and cannot slide out from the smooth plate-like structure side. Therefore, this structure can effectively prevent the limit button 3 from accidentally coming out and ensure the locking firmness of the connecting member.

[0039] 1.3 Spring action principle

[0040] As shown in Figure 3 , the spring 204 is installed in the card slot 203 of the second connecting member 2 and cooperates with the cylinder 304 on the pressing plate 301 of the limit button 3. When the pressing plate 301 is pressed, the spring 204 is further compressed to store elastic potential energy. When the pressing plate 301 is released, the spring 204 releases the elastic potential energy, pushing the double buckle body 303 to quickly reset and be stuck between the tooth-shaped protrusions 1011 of the protruding portion 101 to achieve quick locking.

[0041] Under the action of the spring, the double buckle body of the limit button is stuck between the tooth-shaped protrusions of the protruding portion. Since one side of the protruding portion is a smooth plate-like structure and the other side is a tooth-shaped protrusion, it can prevent the limit button from sliding out, thereby realizing the fixation of the first connecting member and the second connecting member. When the angle needs to be adjusted, press the pressing plate of the limit button to compress the spring, so that the double buckle body is separated from the tooth-shaped protrusion. At this time, the first connecting member can rotate around the long screw. After adjusting to the required angle, release the pressing plate, and the spring resets, pushing the double buckle body to be stuck between the new tooth-shaped protrusions to complete the angle adjustment and positioning. II. Specific implementation method:

[0043] Manufacture the first connecting piece, the second connecting piece and the limit button separately by means of casting, forging or injection molding using suitable materials such as metal or high-strength plastic. Ensure the dimensional accuracy and surface quality of each component; machine an insertion part at one end of the first connecting piece for connecting other pipe fittings. Machine a convex part at the other end. One side of the convex part is a smooth plate-like structure, and multiple intermittently arranged tooth-shaped protrusions are machined on the other side in a circumferential distribution; machine an assembly groove, a through hole, a through-bore and a clamping groove on the second connecting piece. The size of the assembly groove should match the convex part of the first connecting piece, the shape of the through hole should be the same as the cross-sectional shapes of the double snap bodies and two adjacent tooth-shaped protrusions, the through-bore is used for installing long screws, and the clamping groove is used for installing the limit button and the spring; manufacture the limit button, including a pressing plate, a connecting rod and double snap bodies. Ensure that the shape of the double snap bodies matches the tooth-shaped protrusions. Machine a cylinder on the pressing plate for cooperating with the spring; prepare long screws and springs. The long screws should match the through-bores, and the elastic coefficient of the springs should be selected according to actual requirements.

[0044] Installation process: Insert the convex part of the first connecting piece into the assembly groove of the second connecting piece, ensure that the tooth-shaped protrusions of the convex part face the direction of the through hole, pass the long screws through the through-bores on the second connecting piece and the convex part, so that the first connecting piece can rotate freely around the long screws, place the springs into the clamping grooves of the second connecting piece, and then insert the cylinders of the limit buttons into the springs to install the limit buttons in the clamping grooves. Ensure that the double snap bodies of the limit buttons fit tightly with the tooth-shaped protrusions of the convex part.

[0045] Usage method: Insert the pipe fittings to be connected into the insertion parts of the first connecting piece and the second connecting piece, and welding, threaded connection or other suitable connection methods can be adopted. Adjust the angle: When the angle of the pipe fittings needs to be adjusted, press the pressing plate of the limit button to separate the double snap bodies from the tooth-shaped protrusions of the convex part. At this time, the first connecting piece can rotate freely around the long screws. After adjusting to the required angle, release the pressing plate, the springs reset, and the double snap bodies are stuck between the new tooth-shaped protrusions to achieve angle locking.

[0046] The above describes the present utility model and its embodiments. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design similar structural modes and embodiments to this technical solution without creative efforts, and all should fall within the protection scope of the present utility model.
