In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The present application relates to a manhole cover, which comprises a manhole cover lock, and the manhole cover is locked and fixed by the manhole cover lock.

[0033] The other structures and operations of the manhole cover have been recorded in the relevant technology for ordinary technicians in this field and will not be described in detail here. The structure of the manhole cover lock will be introduced below.

[0034] The present application relates to a manhole cover lock, which includes a lock seat 100 and a lock pin 200. The lock pin 200 is arranged on the manhole cover, the lock seat 100 is fixedly arranged, and the lock seat 100 is provided with a locking area 110. The locking area 110 is formed in the lock seat 100 as a structure with an inner cavity. When the manhole cover is closed, the lock pin 200 is used to insert into the locking area 110. The manhole cover lock includes a lock tongue 300, the lock tongue 300 is used to insert into the locking area 110, and the lock tongue 300 is connected to the lock pin 200 to lock the lock pin 200 and prevent the lock pin 200 from withdrawing from the locking area 110, thereby locking the manhole cover. In conjunction with the accompanying drawings, the lock pin 200 is inserted into the locking area 110 from top to bottom, and the lock tongue 300 is inserted into the locking area 110 horizontally. In the locking area 110, the lock tongue 300 and the lock pin 200 are vertically staggered to achieve a snap connection.

[0035] Furthermore, a floating block 120 is provided at the bottom of the locking area 110. The floating block 120 is used to prevent the lock tongue 300 from being inserted into the locking area 110, and to prevent the lock tongue 300 from being inserted into the locking area 110 due to misoperation, so that the lock pin 200 cannot be inserted into the locking area 110, resulting in the manhole cover being unable to be closed and locked. Specifically, when the lock pin 200 is not inserted into the locking area 110, the floating block 120 is at the position where the lock tongue 300 is inserted into the locking area 110. When the lock tongue 300 is inserted into the locking area 110, the floating block 120 blocks the lock tongue 300, so that the lock tongue 300 cannot be inserted. In the related art, the lock tongue 300 is also designed to be able to automatically lock and automatically insert into the locking area 110. This situation will undoubtedly hinder the lock pin 200 from being inserted into the locking area 110, so it is necessary to design the floating block 120 to block the lock tongue 300.

[0036] The manhole cover lock is designed so that the floating block 120 can move in the locking area 110 to avoid the lock tongue 300. Specifically, when the lock pin 200 is inserted into the locking area 110, the floating block 120 is pressed to move the floating block 120, so that the floating block 120 can avoid the lock tongue 300. At this time, the lock tongue 300 can be inserted into the locking area 110 and engaged with the lock pin 200. In this case, the action of the lock pin 200 pressing the floating block 120 is used to achieve the floating block 120 avoiding the lock tongue 300, which can reduce the operation of locking the manhole cover, and there is no need to operate the floating block 120 additionally, saving time and effort.

[0037] As an embodiment, the floating block 120 is connected to the bottom of the locking area 110 through an elastic component. Under the action of the elastic component, the floating block 120 can approach or move away from the bottom of the locking area 110, so that the floating block 120 can float in the locking area 110. It can be understood that the locking pin 200 presses down the floating block 120, and the elastic component is compressed to store energy. After the manhole cover is opened and the locking pin 200 withdraws from the locking area 110, under the action of the elastic component, the floating block 120 automatically moves to a position that blocks the insertion of the locking tongue 300.

[0038] Specifically, the elastic component includes a floating elastic member, the two ends of which respectively abut the bottom of the locking area 110 and the floating block 120, and the floating elastic member can generate elastic potential energy when under pressure. Further, at least two floating elastic members are provided to make the floating block 120 evenly stressed.

[0039] Further, the elastic component includes a first connecting member 121, and the first connecting member 121 is provided with at least two, the first connecting member 121 penetrates the floating block 120 and is connected to the bottom of the locking area 110, and the floating elastic member is sleeved on the outside of the first connecting member 121, and the floating elastic member is provided as a compression spring. It can be understood that the first connecting member 121 plays the role of installing the floating block 120 and the floating elastic member on the one hand, and plays the role of limiting the moving direction of the floating block 120 on the other hand, and plays a guiding role.

[0040] In some examples, the first connecting member 121 is configured as a threaded rod, a bolt, or a screw.

[0041] As an embodiment, the lock base 100 is provided with a first through-area 111 for inserting the lock tongue 300 on the side wall of the locking area 110, and the lock pin 200 is provided with a second through-area 210 for the lock tongue 300 to pass through. It can be understood that after the lock pin 200 is inserted into the locking area 110, the second through-area 210 and the first through-area are in an interlocking position, so that the lock tongue 300 passes through the first through-area 111 and is inserted into the second through-area 210 to achieve the clamping connection with the lock pin 200.

[0042] Furthermore, along the direction in which the lock tongue 300 is inserted into the locking area 110, first penetration areas 111 are respectively provided on two opposite side walls of the locking area 110. In this case, after locking, the lock tongue 300 sequentially penetrates the first penetration area 111 on one side of the locking area 110, the second penetration area 210 of the lock pin 200, and the first penetration area 111 on the other side of the locking area 110, and the side walls on both sides of the locking area 110 exert force on the lock tongue 300, which can improve the clamping strength between the lock tongue 300 and the lock pin 200, and improve the reliability of the manhole cover locking.

[0043] It is understandable that, when the lock pin 200 is separated from the lock base 100, the floating block 120 at least partially blocks the first penetration area 111, and when the lock pin 200 is inserted into the locking area 110, the floating block 120 is moved to a position avoiding the first penetration area 111 by the pressure of the lock pin 200. It should be noted that, when the floating block 120 partially blocks the first penetration area 111, the portion blocked by the floating block 120 should be sufficient to prevent the lock tongue 300 from entering the first penetration area 111.

[0044] In conjunction with the accompanying drawings, the floating block 120 is set to a straight side surface on the side facing the first penetration area 111, and is perpendicular to the direction in which the lock tongue 300 is inserted into the locking area 110, so that the side surface of the floating block 120 can directly abut the end of the lock tongue 300 to ensure that the floating block 120 can block the column lock tongue 300.

[0045] As an embodiment, a recessed pressure area 122 is provided on the side of the floating block 120 facing the locking pin 200. When the locking pin 200 is inserted into the locking area 110, the end of the locking pin 200 at least partially abuts against the pressure area 122, so that the locking pin 200 and the floating block 120 are accurately positioned and the pressure applied by the locking pin 200 to the floating block 120 can be ensured to be stable.

[0046] In conjunction with the accompanying drawings, the pressure area 122 is formed as a groove on the side of the floating block 120, and the two ends of the groove extend to the edge of the floating block 120 to form a notch. Further, the lock pin 200 is provided with a pressure rod 220, and the pressure rod 220 is provided on the lock pin 200 for pressing the end of the floating block 120, and the pressure rod 220 is used to press the floating block 120. Specifically, when the lock pin 200 presses the floating block 120, the pressure rod 220 abuts against the pressure area 122, and the pressure rod 220 is located in the groove formed by the pressure area 122.

[0047] In some embodiments, the second penetration area 210 extends to the end of the locking pin 200 to form a notch, and the pressure rod 220 is disposed at the notch formed by the second penetration area 210. In conjunction with the drawings, the second penetration area 210 is formed into a U-shaped notch facing the end of the locking pin 200 for pressing the floating block 120, and the pressure rod 220 is disposed near the end of the U-shaped notch.

[0048] It is understandable that, on the one hand, when the lock pin 200 presses down the floating block 120, the pressure rod 220 abuts against the floating block 120. On the other hand, when the lock tongue 300 is engaged with the lock pin 200, the pressure rod 220 is located at the lower side of the lock tongue 300, and the lock tongue 300 achieves engagement and fixation of the lock pin 200 by limiting the pressure rod 220, thereby preventing the lock pin 200 from withdrawing from the locking area 110.

[0049] As an embodiment, the manhole cover lock includes a lock housing, the lock housing is fixedly arranged, a lock tongue 300 is arranged in the lock housing, and the lock tongue 300 is movable in the lock housing, and a lock seat 100 is arranged on the lock housing. In conjunction with the accompanying drawings, the lock seat 100 is arranged on the top of the lock housing, and the bottom of the lock seat 100 protrudes downward to form a hollow locking area 110, so that the lock seat 100 is formed into a T-shaped shape.

[0050] As an embodiment, the lock tongue 300 rotates and is inserted into the locking area 110 along an arc trajectory. Specifically, the manhole cover lock is provided with a rotatable lock core in the lock housing, the lock tongue 300 is connected to the lock core, and the lock core drives the lock tongue 300 to rotate so that the lock tongue 300 is inserted into or withdrawn from the locking area 110.

[0051] Furthermore, the locking tongue 300 has a shape formed along an arc track.

[0052] As another alternative implementation, the locking tongue 300 is inserted into the locking area 110 along a straight track, and the locking tongue 300 is inserted into the locking area 110 laterally.

[0054] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
