[0023] The following will further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0024] As Figures 1-3As shown in the figure, the utility model is a municipal manhole cover with a falling prevention function, including a bottom plate 1. In the middle above the bottom plate 1, there is a support ring 2. The upper end inside the support ring 2 is movably connected to the manhole cover body 3 through a pin shaft. On one side of the manhole cover body 3 away from the pin shaft, there is a through groove 4. Below the through groove 4 of the manhole cover body 3, there are four fixing rods 5 arranged in a matrix. The lower part of the fixing rod 5 is fixedly connected to a first fixing block 6. In the middle above the first fixing block 6, there is a guide tube 7. A connecting rod 8 is inserted in the middle of the guide tube 7, and the connecting rod 8 is movably connected with the guide tube 7. The connecting rod 8 can move vertically inside the guide tube 7. At one end of the connecting rod 8 inside the guide tube 7, there is a limit plate 10. Above the limit plate 10 of the connecting rod 8, there is a first spring 11 sleeved. Below the guide tube 7 of the first fixing block 6, there is a first guide groove 12. At one end of the connecting rod 8 inside the first guide groove 12, there is a pressing block 13. The first guide groove 12 can guide and limit the pressing block 13. On both sides at the lower end of the first guide groove 12 of the first fixing block 6, there are second guide grooves 14. A positioning block 15 is arranged in the second guide groove 14. The second guide groove 14 can guide and limit the positioning block 15. On both sides of the first fixing block 6 on the bottom plate 1, there are second fixing blocks 16. A positioning groove 17 matching the positioning block 15 is opened on the second fixing block 16. When the manhole cover body 3 covers the upper end of the support ring 2, under the action of the elastic force of the first spring 11, the first spring 11 pushes the limit plate 10 and the connecting rod 8 to move vertically. Under the action of the elastic force of the first spring 11, the pressing block 13 squeezes the positioning block 15, and the positioning block 15 moves towards the second fixing block 16 side inside the second guide groove 14, so that the positioning block 15 is inserted into the positioning groove 17. Through the mutual cooperation between the positioning block 15 and the positioning groove 17, the manhole cover body 3 can be stably covered on the upper end of the support ring 2.

[0025] One side of the positioning block 15 close to the positioning groove 17 is set as an arc surface. The setting of the arc surface makes it easier for the positioning block 15 to be inserted into the positioning groove 17.

[0026] The upper part of the connecting rod 8 is fixedly connected to a pull ring 9. The setting of the pull ring 9 makes it more convenient for the staff to pull the connecting rod 8.

[0027] The cross section of the pressing block 13 is an inverted cone, and the positioning block 15 is provided with an inclined surface matching the inverted cone.

[0028] Above the positioning block 15, there is a slider 18. On the first fixing block 6, there is a chute 19 that matches the slider 18. The side of the slider 18 away from the pressing block 13 is fixedly connected to the side wall of the chute 19 through a second spring 20. The slider 18 can slide inside the chute 19. Through the mutual cooperation between the slider 18 and the chute 19, the moving stability of the positioning block 15 is effectively improved. When the pressing block 13 no longer squeezes the positioning block 15, under the elastic force of the second spring 20, the slider 18 drives the positioning block 15 to slide, so that the positioning block 15 can automatically disengage from the inside of the positioning groove 17.

[0029] On both sides of the manhole cover body 3, there are drainage holes 21. Rainwater can enter the drain pipe below the manhole cover body 3 through the drainage holes 21.

[0030] Between the bottom plate 1 and the support ring 2, there are multiple reinforcing plates 22 arranged in a matrix. The reinforcing plates 22 effectively increase the overall structural strength of the manhole cover.

[0031] On the outer side of the support ring 2 of the bottom plate 1, there are multiple mounting grooves 23 arranged in a matrix. The manhole cover can be fixedly installed through the mounting grooves 23.

[0032] Specifically, in the present utility model, when the manhole cover body 3 covers the upper end of the support ring 2, under the elastic force of the first spring 11, the first spring 11 pushes the limiting plate 10 and the connecting rod 8 downward. Under the elastic force of the first spring 11, the pressing block 13 squeezes the positioning block 15, and the positioning block 15 moves towards the side of the second fixing block 16 inside the second guiding groove 14. The positioning block 15 is inserted into the positioning groove 17. Through the mutual cooperation between the positioning block 15 and the positioning groove 17, the manhole cover body 3 can be stably covered on the upper end of the support ring 2. When opening the manhole cover body 3, by pulling the pull ring 9 through the through groove 4, the pull ring 9 drives the connecting rod 8 and the pressing block 13 to move upward. When the pressing block 13 no longer squeezes the positioning block 15, under the elastic force of the second spring 20, the slider 18 drives the positioning block 15 to slide, so that the positioning block 15 can automatically disengage from the inside of the positioning groove 17. At this time, the manhole cover body 3 can rotate around the support ring 2, and thus the manhole cover body 3 can be opened.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
