Technical Field

[0001] The utility model relates to the technical field of well covers, in particular to a well cover with a stainless steel lock. Background Technique

[0002] Well covers are used to cover roads or deep wells at home to prevent people or objects from falling. In urban construction, the underground drainage system is crucial. To facilitate the maintenance and cleaning of the drainage system, deep wells are usually set at predetermined positions, and the top of the well is sealed with a well cover.

[0003] Existing well covers are all placed on the well cover seat. When the sewer backs up or when impacted by a vehicle, the well cover is likely to warp, and even pop out, affecting traffic safety. For this reason, we propose a well cover with a stainless steel lock. Summary of the Utility Model

[0004] In view of the deficiency that the existing well cover directly placed on the well cover seat will be washed open when the sewer backs up, the utility model provides a well cover with a stainless steel lock, which has the advantages that after the well cover is placed in the well cover seat, the well cover and the well cover seat are firmly hooked on the well cover seat through triangular clamping blocks, with large connection strength and no loosening, and solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A well cover with a stainless steel lock includes a well cover and a well cover seat. One side of the well cover is rotatably connected to one side of the well cover seat, and further includes a stainless steel lock, which includes a connecting part and a fixing part;

[0006] The connecting part includes two parallel rotating shafts. Both ends of the rotating shafts are rotatably connected in the mounting seats, and strip-shaped plates are respectively connected to the middle parts of the two rotating shafts. Triangular clamping blocks are respectively connected to the opposite sides of the other ends of the two strip-shaped plates. Elastic components are respectively arranged on the two rotating shafts. Driven by the elastic components, the two triangular clamping blocks approach each other;

[0007] The fixing part includes a mounting seat body, a lock hole is provided on the mounting seat body, and a strip-shaped limiting seat is installed at the middle position of the lock hole, and the strip-shaped limiting seat divides the lock hole into two;

[0008] Among them, the connecting part is arranged on the well cover, the fixing part is arranged in the well cover seat, and the lock hole corresponds to the positions of the two strip-shaped plates. After the well cover is placed in the well cover seat, the two strip-shaped plates are distributed on both sides of the strip-shaped limiting seat, and the triangular clamping blocks are hooked under the strip-shaped limiting seat.

[0009] Preferably, the elastic component includes a torsion spring sleeved on the rotating shaft. The number of torsion springs on each rotating shaft is at least one, and one end of the torsion spring is connected to the strip-shaped plate, and the other end is connected to the mounting seat.

[0010] Preferably, the manhole cover includes a cover plate, a reinforcement ring is provided at the bottom edge of the cover plate, and the mounting seat is arranged at the bottom edge of the cover plate.

[0011] Preferably, the manhole cover seat includes an annular seat, a placement groove is provided at the top of the inner edge of the annular seat, the cover plate and the reinforcement ring are placed in the placement groove, and the mounting seat body is arranged at the bottom of the inner edge of the annular seat.

[0012] Preferably, a support is provided at the center of the annular seat, and the side surfaces of the support are connected to the annular seat via a plurality of brackets;

[0013] An annular ring is provided at the center of the cover plate, and the annular ring and the reinforcement ring are connected by multiple reinforcement ribs. The reinforcement ribs are connected to the cover plate, and multiple annular reinforcement rings connected to the reinforcement ribs are also provided at the bottom of the cover plate;

[0014] When the manhole cover is placed in the manhole cover seat, the support is placed in the annular ring and the top of the support contacts the bottom surface of the cover plate.

[0015] Preferably, a strip-shaped opening is provided on the cover plate between the two rotating shafts, and circular openings are provided in the middle of both sides of the strip-shaped opening;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a manhole cover with a stainless steel lock, including a manhole cover and a manhole cover seat.

[0032] The specific structure of the manhole cover seat is as follows. It includes an annular seat 1. At the bottom of the outer edge of the annular seat 1, there is an outwardly extending annular support edge 4. The annular support edge 4 is provided with multiple grooves and is connected to the annular seat 1 through multiple triangular plates, which can strengthen the strength between the annular support edge 4 and the annular seat. At the top of the inner edge of the annular seat 1, there is a placement groove 5. At the center of the annular seat 1, there is a support 11. The side of the support 11 is connected to the annular seat 1 through multiple brackets 12. The brackets 12 are specifically connected to the bottom position of the inner wall of the annular seat 1 to prevent interference with the installation of the manhole cover;

[0033] The specific structure of the manhole cover is as follows. The manhole cover includes a cover plate 6. At the bottom edge of the cover plate 6, there is a reinforcement ring 13. At the center of the cover plate 6, there is an annular ring 15. The annular ring 15 and the reinforcement ring 13 are connected through multiple reinforcement ribs 14. The reinforcement ribs 14 are connected to the cover plate 6. At the bottom of the cover plate 6, there are also multiple annular reinforcement rings 16 connected to the reinforcement ribs 14. After the cover plate 6 is reinforced by the reinforcement ring 13, the reinforcement ribs 14 and the annular reinforcement rings 16, the compressive and bending resistance capabilities of the cover plate 6 are significantly improved, enabling the manhole cover to have better bearing capacity;

[0034] When the manhole cover is in use, the cover plate 6 and the reinforcement ring 13 are placed in the placement groove 5. After the manhole cover is placed in the manhole cover seat, the support 11 is placed in the annular ring 15 and its top contacts the bottom surface of the cover plate 6, that is, the support 11 supports at the center of the cover plate 6. Because when the manhole cover is in use, its center is suspended, and when a relatively large pressure is applied to its surface, the center of the manhole cover is most likely to bend. Therefore, in this application, the center of the manhole cover is supported by the support 11, which can strengthen the strength of the manhole cover.

[0035] Regarding the connection relationship between the manhole cover and the manhole cover seat, as Figure 1 and Figure 2 shown, one side of the manhole cover is rotatably connected to one side of the manhole cover seat. In the actual application process, a U-shaped seat 2 is provided on one side of the annular seat 1, and a rotating block 3 is provided at the edge of the reinforcement ring 13. The rotating block 3 is rotatably installed in the U-shaped seat 2 through a rotating shaft. When the manhole cover is rotated, the edge of the manhole cover can rotate together with the rotating block 3 in the U-shaped seat 2, and the manhole cover can be opened and closed.

[0036] This application also includes a stainless steel lock. The stainless steel lock includes a connection part and a fixed part. The connection part is arranged on the manhole cover, and the fixed part is arranged in the manhole cover seat. And the best position of the stainless steel lock is arranged on the side of the manhole cover and the manhole cover seat away from their rotating connection;

[0037] Among them, the connection part includes two parallel rotating shafts 20. Both ends of the rotating shafts 20 are rotatably connected in the mounting seat 19. The mounting seat 19 is made of the same material as the manhole cover. The mounting seat 19 can be welded to the cover plate 6 or installed on the cover plate 6 by means of bolt fastening. As Figure 2As shown, the specific position of the mounting seat 19 is set at the bottom edge of the cover plate 6, and the middle of the two rotating shafts 20 is respectively connected to the strip plate 18, and the triangular clamping block 17 is connected to the other side of the other end of the two strip plates 18. The two rotating shafts 20 are respectively provided with an elastic component. Under the drive of the elastic component, the two triangular clamping blocks 17 are close to each other. The elastic component can be a torsion spring 24 sleeved on the rotating shaft 20. There is at least one torsion spring 24 on each rotating shaft 20, and one end of the torsion spring 24 is connected to the strip plate 18 and the other end is connected to the mounting seat 19.

[0038] The fixing part includes a mounting seat body 23, such as Figure 3 As shown, the mounting seat body 23 is arranged at the bottom of the inner edge of the annular seat 1, and a lock hole 22 is provided on the mounting seat body 23. The lock hole 22 is a rectangular hole. A strip-shaped limit seat 21 is installed in the middle of the lock hole 22. The strip-shaped limit seat 21 divides the lock hole 22 into two. The mounting seat body 23 and the annular seat 1 are made of the same material and the two are an integrated structure. The strip-shaped limit seat 21 is preferably made of stainless steel to prevent it from rusting and reducing the connection strength. Its two ends can be fastened to the mounting seat body 23 by bolts or welded;

[0039] It should be noted that the lock hole 22 corresponds to the position of the two strip plates 18. Figure 6 As shown, the bottoms of the two triangular blocks 17 are both inclined surfaces, that is, the bottoms of the two triangular blocks 17 form an inverted "V"-shaped structure, and the top of the strip limit seat 21 is arc-shaped. When the manhole cover is placed in the manhole cover seat, the bottoms of the two triangular blocks 17 first contact the top of the strip limit seat 21. As the manhole cover gradually sinks, the two triangular blocks 17 are supported by the strip limit seat 21, and finally the two strip plates 18 are distributed on both sides of the strip limit seat 21. The triangular blocks 17 are hooked under the strip limit seat 21. At this time, the manhole cover is firmly locked on the manhole cover seat and will not loosen.

[0040] The rotating shaft 20, the strip plate 18 and the triangular clamping block 17 are all made of stainless steel, which can prevent them from rusting and reducing the connection strength.

[0041] In order to facilitate the opening of the manhole cover, it also includes a key to open the stainless steel lock. A strip opening 8 is provided on the cover plate 6 between the two rotating shafts 20. A circular opening 7 is provided in the middle of both sides of the strip opening 8. The strip opening 8 and the circular opening 7 constitute a key opening.

[0042] The key comprises a rod 10, the bottom of which is connected to two parallel cylindrical heads 9, both ends of which protrude from the rod 10, and a handle is provided on the top of the rod 10;

[0043] The diameter of the rod body 10 is larger than that of the cylindrical head 9. The rod body 10 is placed in the circular opening 7, and the cylindrical head 9 is placed in the strip opening 8. After the rod body 10 is placed in the circular opening 7, it is limited and can only move and rotate in a straight line up and down. Therefore, when the bottom of the rod body 10 is against the strip limit seat 21, the rotating rod body 10 is rotated 90°. The two ends of the cylindrical head 9 at the bottom of the rod body 10 are respectively against the two strip plates 18. The cylindrical head 9 opens the two strip plates 18 and drives the triangular block 17 to separate from the bottom of the strip limit seat 21. At this moment, the most important thing is that Figure 6 As shown, the cylindrical head 9 at the top is just located below the cover plate 6, and the gap between the two is matched, that is, the cylindrical head 9 at the top is also rotated 90°, and it is now perpendicular to the strip opening 8. At this moment, the operator can lift the manhole cover by hand using the handle, while the cylindrical head 9 at the bottom and the two strip plates 18 are always in contact and will not separate.
