[0037] The support column 201d is fixed to the inner wall of the fixed box 201a. The support column 201d can support the moving rod 201c to prevent the moving rod 201c from shifting. A sliding groove is set on one side of the fixed box 201a. The pressure rod 201e slides in the sliding groove. The moving rod 201c can be driven to move by pressing the pressure rod 201e.

[0038] Specifically, the fixing member 201 further includes a first spring 201f and a first fixing seat 201g. The first spring 201f is fixed to the bottom of the moving rod 201c, and the first fixing seat 201g is fixed to the bottom of the first spring 201f.

[0039] When the moving rod 201c is moved, an extrusion force can be applied to the first spring 201f. The movement of the moving rod 201c drives the block 201b to separate from the limiting groove, thereby releasing the limit on the cover 101. After the cover 101 is installed, it is necessary to limit the cover 101. The moving rod 201c is released. At this time, the rebound force of the first spring 201f can drive the block 201b to engage with the limiting groove, thereby limiting the cover 101. The first fixed seat 201g is fixed to the inner wall of the fixed box 201a. The first fixed seat 201g can be provided to support the first spring 201f to prevent the first spring 201f from deviating.

[0041] After the cover 101 is installed in the fixing box 201a, a squeezing force can be applied to the second spring 201h. The rebound force of the second spring 201h can drive the cover 101 to move, so that the block 201b on the cover 101 is more tightly engaged with the limit groove, so as to fix the cover 101 in the fixing box 201a. The second fixing seat 201i is used to support the second spring 201h to prevent the second spring 201h from deviating.

[0042] Specifically, the limiting member 202 includes a limiting gear 202a and a gear sleeve 202b. The limiting gear 202a is sleeved on the outside of the movable rod 102, and the gear sleeve 202b is sleeved on the outside of the limiting gear 202a. A limiting groove X is set on one side of the positioning plate 103, and one end of the gear sleeve 202b is set in the limiting groove X.

[0043] A tooth groove is provided on the tooth sleeve 202b, and the tooth groove is engaged with the limit gear 202a. The movable rod 102 can be limited by the engagement of the tooth groove with the limit gear 202a to prevent the movable rod 102 from rotating, thereby limiting the cover 101. The tooth sleeve 202b is movably connected to the movable rod 102. When it is necessary to release the limit on the movable rod 102, the tooth groove and the limit gear 202a can be separated by moving the tooth sleeve 202b, thereby allowing the movable rod 102 to rotate so that the cover 101 can be opened.

[0044] Example 3

[0045] Reference Figure 3 and Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0046] Specifically, the limiting member 202 further includes a pull plate 202c, a third spring 202d and a positioning plate 202e, the pull plate 202c is sleeved on the outside of the gear sleeve 202b, the third spring 202d is fixed to one side of the gear sleeve 202b, and the positioning plate 202e is fixed to one end of the third spring 202d.

[0047] The positioning plate 202e is fixed to one end of the movable rod 102. When it is necessary to separate the tooth groove from the limit gear 202a, the pull plate 202c is pulled, and the pull plate 202c drives the tooth sleeve 202b to move. At this time, the setting of the positioning plate 202e can apply a squeezing force to the third spring 202d when the tooth sleeve 202b moves, so that the tooth groove can be separated from the limit gear 202a, and then the cover 101 can be opened. After closing the cover 101, in order to prevent the cover 101 from being accidentally touched and opened automatically, the pull plate 202c is released. At this time, the rebound force of the third spring 202d can drive the tooth groove to move and engage with the limit gear 202a, so that the limit gear 202a can be limited to prevent the cover 101 from being accidentally touched and opened automatically.

[0048] When in use, when the cover plate 101 needs to be installed, the cover plate 101 is first placed in the fixing box 201a. At this time, the limit grooves on both sides of the cover plate 101 are engaged with the clamping blocks 201b. After the cover plate 101 is installed in the fixing box 201a, an extrusion force can be applied to the second spring 201h. The rebound force of the second spring 201h can drive the cover plate 101 to move, so that the clamping blocks 201b on the cover plate 101 are more closely engaged with the limit grooves. To fasten the cover 101 in the fixing box 201a, when the cover 101 needs to be removed, the pressure rod 201e is pressed, and the pressure rod 201e drives the moving rod 201c to move. When the moving rod 201c is moved, a squeezing force can be applied to the first spring 201f. The movement of the moving rod 201c drives the block 201b to separate from the limiting groove, thereby releasing the limit on the cover 101 so that the cover 101 can be removed.

[0049] When it is necessary to open the cover 101, the pull plate 202c is pulled, and the pull plate 202c drives the gear sleeve 202b to move. At this time, the positioning plate 202e can be set to apply a squeezing force to the third spring 202d when the gear sleeve 202b moves, so that the tooth groove can be separated from the limit gear 202a, thereby releasing the limit on the movable rod 102, so that the cover 101 can be opened. When it is necessary to cover the foundation pit monitoring hole, the cover 101 can be closed to cover the foundation pit monitoring hole. After the cover 101 is closed, it is necessary to limit the cover 101 to prevent the cover 101 from being accidentally touched and opened automatically. The pull plate 202c is released. At this time, the rebound force of the third spring 202d can drive the tooth groove to move and engage with the limit gear 202a, so that the limit gear 202a can be limited to prevent the cover 101 from being accidentally touched and opened automatically.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
