The solution adopted by the utility model to solve the technical problem is that a manhole cover structure includes a manhole cover casting and a well seat casting, and the manhole cover connector at one end of the well seat casting is provided with a cavity for the installation and rotation of the manhole cover casting. One side of the cavity is provided with a boss, and the well cover casting is provided with a slideway groove for embedding the boss for hinged rotation, and the other end of the well cover casting is provided with an arc-shaped elastic arm, and one end of the elastic arm It is fixedly connected with the manhole cover casting, and the other end is suspended in the air and is provided with an inclined-plane bump for extrusion. The well seat casting is provided with an inclined-plane concave hole that is extruded and self-locked with the inclined-plane protrusion. The manhole cover casting and the well seat casting There is also a buffer device at the joint.

Further, the elastic arm is located at the bottom of the manhole cover casting, and the top of the manhole cover casting is opened with a hook to hook the manhole cover casting at the corresponding position of the elastic arm. The position is provided with a pry opening for prying off the manhole cover casting.

Further, the boss is rectangular and inclined relative to the vertical plane, the slideway groove is composed of a rectangular groove and a circular groove, the rectangular groove is located at the opening of the slideway groove, and the circular groove Located at the bottom of the channel groove.

Further, the rectangular groove at the opening of the slideway groove is provided with a pin driven into a pin hole for locking the boss in the circular groove.

Further, the buffer device includes a number of rubber strip grooves with narrow tops and wide bottoms. The rubber strip grooves are set on the casting of the well seat. Embedded rubber strips are arranged on the rubber strip grooves. The height of the embedded rubber strips is Out of the top surface of the rubber strip groove, the manhole cover casting is extended with a plurality of convex strips for contacting and supporting the embedded rubber strip at the position of the embedded rubber strip.

Further, there are two manhole cover joints of the well cover casting and the well seat casting respectively, and the extension directions of the bosses are consistent.

Compared with the prior art, the utility model has the following beneficial effects: the manhole cover structure adopts an arc-shaped elastic arm structure, which can be self-locked and reduce the impact when the vehicle is rolled, and overcomes the need for existing manhole cover castings when the manhole cover is overdue. Disadvantages where castings may bounce, impact and make noise. Moreover, the pin on the groove of the slideway can lock the boss in the circular groove, which has an anti-theft function. The embedded rubber strip of the buffer device can solve the problem that the traditional rubber strip is easy to fall off, and the processed rubber strip groove and embedded rubber strip can achieve a fixed and uniform height of the embedded rubber strip above the rubber strip groove, ensuring that the casting of the manhole cover is always stable. It will be directly pressed against the well frame, thus further effectively avoiding vibration and noise. Therefore, the utility model is not only a kind of technological innovation, but also beneficial to traffic safety and environmental protection. It is a green product that meets the requirements of safety and environmental protection, and is worthy of vigorous promotion and application.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Figures 1 to 6, a manhole cover structure includes a manhole cover casting 2 and a well seat casting 1. A well cover connector 18 at one end of the well seat casting 1 is provided with a cavity 11 for the installation and rotation of the manhole cover casting 2. , one side of the cavity 11 is provided with a boss 6, and the well cover casting 2 is provided with a slideway groove 7 for embedding the boss 6 for hinge rotation, and the other end of the well cover casting 2 is provided with an arc-shaped Elastic arm 3, one end of the elastic arm 3 is fixedly connected with the manhole cover casting 2, and the other end is suspended in the air and provided with an inclined-plane bump 4 for extruding. The oblique concave hole 5 of the lock, and the junction of the well cover casting 2 and the well seat casting 1 are also provided with a buffer device 8 .

In this embodiment, the elastic arm 3 is located at the bottom of the well cover casting 2, and the top of the well cover casting 2 is provided with a cover lifting hole 9 at the corresponding position of the elastic arm 3 to hook the well cover casting 2, and the well cover The casting 2 is provided with a pry opening 10 for prying off the well cover casting 2 at the edge position beside the cover opening 9 .

In this embodiment, the boss 6 is rectangular and inclined relative to the vertical plane, the slideway groove 7 is composed of a rectangular groove 12 and a circular groove 13, and the rectangular groove 12 is located in the slideway groove 7 At the opening, the circular groove 13 is located at the bottom of the groove 7 of the slideway.

In this embodiment, the rectangular groove 12 at the opening of the slideway groove 7 is provided with a pin 14 driven into a pin hole for locking the boss 6 in the circular groove 13 , which has an anti-theft function.

In this embodiment, the buffer device 8 includes a number of rubber strip grooves 15 that are narrow at the top and wide at the bottom. 16. The embedded rubber strip 16 is higher than the top surface of the rubber strip groove 15, and the manhole cover casting 2 has several convex strips 17 extending on the position of the embedded rubber strip 16 for contacting and supporting the embedded rubber strip 16 , the height of the embedded rubber strip 16 higher than the rubber strip groove 15 is uniform, which can prevent the phenomenon that the existing manhole cover rubber strip falls off, and can greatly improve its buffer capacity, and has anti-noise function.
