DETAILED DESCRIPTION

[0022] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a mahjong machine large plate connection hinge with an integrated mortise and tenon connection, comprising: a fixed seat 1, a rotating seat 2 is rotatably arranged on the fixed seat 1, a limiting seat 3 is fixedly installed on the rotating seat 2, and a limiting component 4 is fixedly installed in the fixed seat 1. The limiting component 4 includes a fixed ring 5 fixedly installed inside the fixed seat 1, a sliding rod 6 rotatably and slidably arranged inside the fixed ring 5, a fixed plate 7 fixedly installed at one end of the sliding rod 6, a limiting plate 8 fixedly installed at the other end of the sliding rod 6, and a spring 9 located between the fixed ring 5 and the fixed plate 7. A guide seat 10 for guiding the rotating seat 2 is fixedly installed on the fixed seat 1.

[0025] In this embodiment, specifically: the fixing base 1 is an L-shaped structure, the fixing base 1 is composed of an integrated bending structure, two first protrusions 101 are provided at the bottom of the fixing base 1, and a plurality of first circular holes are opened on the two first protrusions 101. The opening of the first circular holes facilitates the fixed installation of the fixing base 1.

[0026] In this embodiment, specifically: a second protrusion 102 is provided on the fixed seat 1, the rotating seat 2 is rotatably matched with the second protrusion 102, two fixed blocks 11 are fixedly installed on the second protrusion 102 and rotatably matched with the rotating seat 2, a plurality of second circular holes 103 are opened on the fixed seat 1, and the installation of the second protrusion 102 makes it difficult for the rotating seat 2 to deviate during rotation.

[0027] In this embodiment, specifically: a bolt fastener 12 for fixing the guide seat 10 is fixedly installed on the fixed seat 1, and a first arc hole 201 and a second arc hole 202 are opened on the rotating seat 2. The first arc hole 201 is set to slide with the guide seat 10. The opening of the first arc hole 201 facilitates the sliding cooperation between the guide seat 10 and the rotating seat 2.

[0028] In this embodiment, specifically: the sliding rod 6 is slidably arranged inside the fixed seat 1, the limit seat 3 is fixedly installed on one side of the second arc hole 202, and a plurality of grooves 301 for accommodating the limit plate 8 are opened on the limit seat 3. The opening of the groove 501 facilitates the insertion of the limit plate 8 into the interior of the fixed ring 5, thereby making it difficult for the rotating seat 2 to rotate.

[0029] In this embodiment, specifically: a plurality of third circular holes 203 are provided on the rotating seat 2, and a recess 304 for the second protrusion 102 to pass through is provided on the rotating seat 2.

[0030] The utility model is in operation: when the hinge is working, the fixed seat 1 and the rotating seat 2 need to be fixed on the plate, and the plate to be opened is rotated at this time, and the rotating seat 2 rotates at this time, and when the rotating seat 2 is rotated to a suitable angle, when the plate is opened, the rotating seat 2 rotates at this time, and when the plate is rotated to a suitable angle, the sliding rod 6 is pulled at this time, and after the sliding rod 6 is pulled, the spring 9 is squeezed and contracted at this time, and then the sliding rod 6 and the fixing plate 7 are rotated, and when the fixing plate 7 is rotated, the force pulling the sliding rod 6 is released at this time, and the spring 9 resets the fixing plate 7 and the sliding rod 6, and one end of the fixing plate 7 is inserted into the interior of the limit seat 3 at this time, and the rotating seat 2 stops rotating at this time;

[0031] When the guide seat 10 needs to guide the rotating seat 2, the rotating seat 2 is rotated at this time. During the rotation of the rotating seat 2, the guide seat 10 guides the rotating seat 2, and the rotating seat 2 rotates around the central axis of the guide seat 10.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
