[0001] The utility model relates to the technical field of resin manhole covers, in particular to a resin manhole cover with good high-temperature resistance effect. Background Technique

[0002] The resin manhole cover, also known as the polymer fiberglass reinforced plastic manhole cover or composite material manhole cover, is a manhole cover product made by a specific process, which has the characteristics of strong anti-theft performance, large bearing capacity, high temperature resistance, long service life, etc.

[0003] In the prior art, the resin manhole cover relies on its own weight to buckle on the manhole seat. When some heavy vehicles pass by from the side of the manhole cover, it is easy to cause the manhole cover to tilt and separate from the manhole seat. In addition, the manhole cover can be easily separated from the manhole seat by intentional human movement, and the safety is relatively low. Therefore, we designed a resin manhole cover with good high-temperature resistance effect to solve the above problems. Content of the Utility Model

[0025] A limiting mechanism is fixedly installed on the side wall of one of the limiting plates 10. The limiting mechanism extends into the extrusion mechanism and abuts against its inner side wall. The limiting mechanism includes a first mounting frame 5 fixedly installed on the side wall of the limiting plate 10. A clamping plate 6 is slidably connected in the first mounting frame 5. The clamping plate 6 extends into the clamping groove 14 and abuts against its inner side wall. A jack 7 is opened at the top of the clamping plate 6.

[0027] The functional principle of the present utility model can be described through the following operation methods:

[0028] When it is necessary to install the manhole cover body 2 on the manhole seat 1, first, the operator places the manhole cover body 2 on the manhole seat 1, so that the limiting block 9 at the bottom of the manhole cover body 2 is inserted into the corresponding limiting groove 8 on the manhole seat 1, so that the manhole cover body 2 is embedded in the manhole seat 1. At this time, the operator inserts a plug rod with a diameter smaller than that of the communication hole 3 into the communication hole 3. The operator presses the plug rod downward. The plug rod squeezes the slider 16 to slide downward. The slider 16 drives the ejector rod 17 to slide downward. When the ejector rod 17 slides downward, it squeezes the inclined surface of the trapezoidal block 12. The ejector rod 17 drives the trapezoidal block 12 to slide. The trapezoidal block 12 drives the clamping block 24 to slide through the sliding rod 11, so that the clamping block 24 is inserted into the corresponding slot 22. When the side wall of the clamping block 24 abuts against the inner side wall of the slot 22, the clamping plate 6 slides into the clamping groove 14 under the action of the elastic force of the second spring 18. The clamping plate 6 limits and fixes the slider 16, so that the clamping block 24 is fixed in the slot 22. At this time, the manhole cover body 2 and the manhole seat 1 are stably connected;

[0029] When it is necessary to disassemble the manhole cover body 2 from the manhole seat 1, the operator inserts a plug rod into the first installation frame 5 so that the bottom end of the plug rod enters the jack 7 on the clamping plate 6. Then the operator pulls the plug rod to slide to the right, and the plug rod drives the clamping plate 6 to slide to the right. At this time, the clamping plate 6 disengages from the slot 14 on the slider 16, and the clamping plate 6 releases the fixation of the slider 16. The clamping block 24 slides into the second installation frame 23 under the action of the pulling force of the first spring 13, and the clamping block 24 disengages from the slot 22. Then the manhole cover body 2 can be disassembled from the manhole seat 1.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
