Example

[0024] A type of concrete inspection well that can be opened from the inside, such as Figures 1-5 As shown, the manhole includes a manhole body 1, a manhole cover 2, and a fixed frame 3 fixedly connected to the manhole body 1. The manhole cover 2 is rotatably connected to the fixed frame 3. The fixed frame 3 has a slot 4. The manhole cover 2 is slidably provided with a locking member 5 for embedding into the slot 4. The locking member 5 and the slot 4 cooperate to achieve a fixing effect. The manhole cover 2 is also provided with a locking assembly that pushes the locking member 5 to move. The locking assembly controls the connection between the locking member 5 and the slot 4, achieving the opening and closing effect.

[0025] like Figures 2-3 As shown, the locking member 5 includes a base 6 that is pulsatorically connected to the locking assembly and a locking part 7 that is slidably disposed on the base 6. The locking part 7 has an anti-disengagement outer edge fixedly disposed at one end near the locking assembly, thereby preventing the locking part 7 from falling off the base 6. At the same time, an elastic element 8 is disposed between the base 6 and the locking part 7 to push the locking part 7 to move away from the locking assembly. By utilizing the elastic thrust of the elastic element 8, the locking part 7 is in the extended state under normal conditions, thereby ensuring the fixed effect after being embedded under normal conditions.

[0026] like Figures 2-4As shown, the well body 1 is provided with a pushing assembly for pushing the locking part 7 to move towards the base 6, one end of the pushing assembly extends the inner wall of the well body 1, and the other end is embedded in the slot 4, and the pushing assembly can realize the effect of pushing the locking part 7 to compress the elastic element 8 and thus retreat from the slot 4, so that the manhole cover 2 can also be opened in the well body 1, thereby effectively avoiding someone being trapped and improving safety.

[0027] As shown in the Figures 2-3 , the pushing assembly includes a housing 9 fixedly arranged on the well body 1 and a pushing piece 10 slidingly arranged on the housing 9, and the housing 9 provides a mounting space for the pushing assembly, and the housing 9 is provided with a long opening 17 for the pushing piece 10 to extend to the outside, and the pushing piece 10 abuts against the locking part 7 through the long opening 17, so that the locking part 7 can be pushed out of the slot 4 by pulling and sliding the pushing piece 10.

[0028] As shown in the Figures 2-3 , the pushing assembly further comprises a lever 11 rotatably arranged on the housing 9, a sliding block 12 abutting against one end of the lever 11, and a connecting rod 13 hingedly connected to the sliding block 12 and the pushing piece 10 at both ends, wherein the distance between the rotating point of the lever 11 and the abutting end of the sliding block 12 is less than the distance between the position where the user holds the lever 11 and the rotating point, thereby forming a labor-saving structure to facilitate the user to quickly pull the lever 11 to rotate and thus push the sliding block 12 to move, and the sliding block 12 is slidingly arranged on the housing 9, thereby ensuring the accuracy of the moving direction of the sliding block 12, and the connecting rod 13 is inclined, thereby the sliding block 12 moves upward, and the connecting rod 13 forms a horizontal component force through the inclined arrangement, thereby the connecting rod 13 drives the pushing piece 10 to move horizontally.

[0029] As shown in the Figures 2-3 , the abutting place of the lever 11 and the sliding block 12 is provided with a spherical structure, which reduces the jamming during abutting, and the sliding block 12 is provided with a concave structure, which provides a space for the lever 11, making the overall structure more compact.

[0030] As shown in the Figures 2-4 , the locking assembly includes a lock cylinder 18 arranged on the manhole cover 2, a key 14 for embedding the lock cylinder 18, and a pushing piece 15 fixedly connected to the rotor of the lock cylinder 18, the pushing piece 15 is provided with a cam structure, and the base 6 is provided with a moving frame for the rotation of the pushing piece 15, thereby realizing the effect of reciprocating the moving frame through the rotation of the cam structure, and thus realizing the position of the base 6.

[0031] The lock cylinder 18 adopts a pin tumbler structure, and the lock cylinder 18 includes a lock sleeve, a rotor, a spring and a plurality of pins matched together. Since the pin tumbler structure is a prior structure, it will not be described in detail.

[0032] The inner recess structure is arranged above the inner recess structure, and the cover plate 16 is detachably connected above the inner recess structure, and the cover plate 16 is fixed on the inner recess structure through bolts, so as to reduce the entry of external dust.

[0033] Working principle: when the manhole cover 2 needs to be opened from the outside, first, the cover plate 16 is disassembled, then the key 14 is inserted and then the lock core 18 is rotated, so that the lock core 18 drives the actuator 15 to rotate, the actuator 15 drives the base 6 and the locking part 7 to move away from the insertion slot 4 through the push moving frame, so as to realize the effect of unlocking, and then the manhole cover 2 can be opened.

[0034] When the manhole cover 2 needs to be opened from the inside of the well body 1, the lever 11 is pulled downward to rotate, so that the lever 11 pushes the sliding block 12 to move upward, so that the sliding block 12 drives the pusher 10 to move toward the base 6 through the connecting rod 13, and at this time, the pusher 10 abuts against the locking part 7, so that the locking part 7 is pushed to move together, so that the locking part 7 exits the insertion slot 4, realizing the effect of unlocking, and then the manhole cover 2 can be opened.

[0035] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0036] In addition, it should be understood that although the present application is described in the form of embodiments, each embodiment does not contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can be properly combined to form other embodiments that those skilled in the art can understand.
