[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example: Refer to Figure 1 to Figure 2 A manhole cover for a municipal road includes a manhole cover seat 1, a circular manhole opening 2 is opened in the central position of the manhole cover seat 1, a rotating seat 3 is arranged at the upper end of the manhole cover seat 1, and a manhole cover 4 is rotatably connected to the rotating seat 3. A rotating seat 3 is arranged at the upper end of the manhole cover seat 1, and the rotating seat 3 is made of high-strength, corrosion-resistant metal material to provide stable rotation support for the manhole cover 4. The manhole cover 4 is rotatably connected to it through the rotating seat 3, so that the manhole cover 4 can be flexibly opened and closed when needed.

[0025] The manhole cover seat 1 is provided with a support seat at the position of the wellhead 2, and the manhole cover 4 is located at the upper end of the support seat. The surface of the support seat is flat and has a certain degree of roughness, and the manhole cover 4 is located at the upper end of the support seat. The support seat not only bears the weight of the manhole cover 4 itself, but also effectively disperses the pressure on the manhole cover when vehicles and pedestrians pass by, ensuring that the manhole cover remains stable during long-term use and avoids shaking, displacement, etc.

[0026] An opening cover assembly is arranged inside the manhole cover seat 1. The specific opening cover assembly includes two lifting rods 7 that are slidably penetrated by the manhole cover seat 1. The upper ends of the two lifting rods 7 are fixedly connected with a cross bar 8. The cross bar 8 is made of a solid metal rod and has sufficient strength and toughness, which is convenient for operators to grasp and apply force.

[0027] A plurality of reinforcing seats 5 are arranged at the upper end of the manhole cover seat 1, and one of the reinforcing seats 5 is located in the protective cover 61. The reinforcing seat 5 in the protective cover 61 is provided with a clearance groove 9, and the cross bar 8 is located in the clearance groove 9 to avoid the situation where the box cover 62 cannot cover 61.

[0028] A connecting rod 10 is fixedly connected to the lower sides of the two lifting rods 7. The rod bodies of the two connecting rods 10 are symmetrically fixedly connected to two L-shaped rods 11. A plurality of reinforcing rods 12 are arranged between the two L-shaped rods 11. The reinforcing rods 12 are evenly distributed between the two L-shaped rods 11 and are fixed to the L-shaped rods 11 by welding, which effectively enhances the overall structural strength of the L-shaped rods 11 and prevents the L-shaped rods 11 from deforming during the process of lifting the manhole cover 4.

[0029] When the cross bar 8 is at the highest point, the upper end surfaces of the two L-shaped rods 11 are higher than the upper end surface of the wellhead 2. When the cross bar 8 is at the highest point, the upper end surfaces of the two L-shaped rods 11 are higher than the upper end surface of the wellhead 2. At this time, the long sides of the L-shaped rods 11 can lift the manhole cover 4, overcoming the self-gravity of the manhole cover 4 and the friction between the support seat and the manhole cover 4, so that the manhole cover 4 rotates around the rotating seat 3, ensuring that the operation of opening the manhole cover is completed.

[0030] The upper end of the manhole cover seat 1 is also provided with a protective component 6 for protecting the cover opening component. Specifically, the protective component 6 includes a protective cover 61 fixedly arranged at the upper end of the manhole cover seat 1, a box cover 62 is rotatably arranged on the upper end of the protective cover 61, and a rotating lock buckle 63 is rotatably arranged on the right end of the box cover 62. The right end of the protective cover 61 is fixedly connected with a fixing pin 64, and the fixing pin 64 is horizontally opened with a plurality of upper locking holes 65, and the rotating lock buckle 63 is opened with a through hole that cooperates with the fixing pin 64. The upper locking hole 65 is used in conjunction with a protective lock, and the box cover 62 locks the protective cover 61 firmly and cannot be opened at will, thereby effectively preventing non-staff from touching the cover opening component and avoiding the manhole cover from being easily opened and stolen. When the manhole cover 4 needs to be opened, only the staff equipped with the corresponding key can open the protective lock, rotate and separate the rotating lock buckle 63 from the fixing pin 64, and then rotate the box cover 62 upward to open the protective component 6 and expose the cover opening component for subsequent cover opening operations.

[0031] The working principle of the utility model is as follows:

[0032] The right end of the protective cover 61 is fixedly connected with a fixing pin 64, and the fixing pin 64 is horizontally opened with multiple upper locking holes 65. The size and spacing design of these upper locking holes 65 meet the specifications of the standard protective lock. The rotating lock buckle 63 is opened with a through hole that cooperates with the fixing pin 64. Under normal use, the lock buckle 63 is rotated downward to make its through hole and the fixing pin 64 cooperate, and then the protective lock is locked. The box cover 62 is firmly locked and cannot be opened at will, thereby effectively preventing non-staff from touching the cover opening component and avoiding the manhole cover from being easily opened and stolen.

[0033] When it is necessary to open the manhole cover 4, only the staff can use the corresponding key to open the protective lock, rotate the lock buckle 63 upward to separate it from the fixing pin 64, and then rotate the box cover 62 upward to open the protective assembly 6 to expose the cover opening assembly. The operator holds the cross bar 8 with both hands and pulls the cross bar 8 upward with force. The cross bar 8 moves upward, driving the two lifting rods 7 fixed to it to move upward synchronously. Since the lower sides of the two lifting rods 7 are connected by the connecting rod 10, and the L-shaped rods 11 are symmetrically fixed on the connecting rod 10, the L-shaped rods 11 will also move upward with the lifting rods 7. When the cross bar 8 moves to the highest point, the upper end surfaces of the two L-shaped rods 11 are higher than the upper end surface of the wellhead 2. At this time, the long side of the L-shaped rod 11 can lift the manhole cover 4, overcome the self-gravity of the manhole cover 4 and the friction between the support seat and the manhole cover 4, so that the manhole cover 4 rotates around the rotating seat 3, thereby completing the operation of opening the manhole cover.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
