Description

Technical Field

[0001] This utility model relates to a hinged connection structure and belongs to the field of mechanical equipment technology. Background Technology

[0002] A hinge is a mechanical connection that connects two objects, allowing each object to retain some degrees of freedom of movement. The relative motion between the two objects is conditional and is a common type of mechanical connection. In practical applications, hinges are frequently encountered between a straight connector 1 and an H-shaped connector 2, such as... Figure 1 The current conventional approach involves creating a connecting hole in the H-shaped connector, inserting a pin into the hole, and then fitting a sleeve onto the pin in the I-shaped connector 1 to complete the hinged connection. This conventional hinged connection structure requires machining the connecting hole, sleeve, and pin, involving numerous processing steps and materials, resulting in relatively high costs and making it unsuitable for mass production. Therefore, there is an urgent need for a new hinged connection structure that is simple in structure and low in cost to reduce the manufacturing cost of the equipment. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a new type of hinged connection structure that is simple in structure and low in cost, thereby reducing the manufacturing cost of the equipment.

[0004] The purpose of this utility model is achieved as follows:

[0005] A hinged connection structure includes a straight connector and an H-shaped connector. An integrally formed T-shaped connector is installed on the straight connector, and a connection through hole is provided on the H-shaped connector. Both ends of the T-shaped connector are provided with connecting parts that are movably connected to the connection through hole. The connecting part is provided with a cylindrical boss that is movably embedded in the connection through hole.

[0006] Furthermore, the T-shaped connector is integrally injection molded from engineering plastic.

[0007] Furthermore, the engineering plastic is glass fiber reinforced nylon.

[0008] Furthermore, the two sides of the T-shaped connector are provided with reinforcing sheets, and the reinforcing sheets and the connecting part are provided with a conical structure for transition.

[0009] Furthermore, the cylindrical boss of the connecting part is replaced with a threaded countersunk hole, and the connecting part is movably connected to the connecting through hole through bolts and the threaded countersunk hole.

[0010] Furthermore, the two connecting parts of the T-shaped connector have a cylindrical boss on one side and a threaded countersunk hole on the other.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a T-shaped connector with a T-shaped structure as the main structure of the hinged connection. Connecting parts are set on both sides of the T-shaped connector to movably connect with the H-shaped connector, which simplifies the hinged connection structure, makes assembly convenient, reduces costs, and is suitable for mass production.

[0019] Example 1

[0020] See Figure 2 This utility model relates to a hinged connection structure, comprising a straight connector 1 and an H-shaped connector 2. A T-shaped connector 3, integrally injection molded from engineering plastic, is mounted on the straight connector 1. A connecting through hole 4 is provided on the H-shaped connector 2. The T-shaped connector 3 has connecting portions 5 at both ends that are movably connected to the connecting through hole 4. The connecting portion 5 has a cylindrical boss that is movably embedded in the connecting through hole 4.

[0021] To ensure sufficient structural strength of the connector and the service life of the hinge point, glass fiber reinforced nylon is used as the body material of the T-shaped connector 3, and reinforcing sheets 6 are provided on both sides of the T-shaped connector 3. The reinforcing sheets 6 and the connecting part 5 are provided with a conical structure 7 for transition, so as to prevent stress concentration at the root of the connecting part of the cylindrical boss and premature damage.

[0022] This utility model adopts a T-shaped connector 3 with an integrated structure as the main body of the hinge structure. The connecting parts on both sides of the T-shaped connector 3 are movably connected with the H-shaped connector 2, realizing the hinge connection between the straight connector 1 and the H-shaped connector 2. This simplifies the hinge connection structure between the two, makes assembly simple and low-cost, and is suitable for mass production.

[0023] Example 2

[0024] See Figure 3 In Embodiment 1, the cylindrical bosses on both sides of the connecting part 5 are replaced with threaded countersunk holes. The connecting part 5 is movably connected to the connecting through hole 4 by bolts and threaded countersunk holes. This situation is applicable when the H-shaped connector 2 cannot be disassembled or has high rigidity, and the bosses on both sides cannot be simultaneously inserted into the connecting through hole 4.

[0025] Example 3

[0026] See Figure 4 In conjunction with Embodiments 1 and 2, the two connecting parts 5 of the T-shaped connector 3 are provided with a cylindrical boss on one side and a threaded countersunk hole on the other side. The cylindrical boss is first inserted into a connecting through hole 4 of the H-shaped connector 2, and then the other connecting through hole 4 is connected by bolts and threaded countersunk holes, which can further simplify the assembly steps of the hinged connection.

[0027] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
