Description

Technical Field

[0001] The utility model relates to a manhole cover with fine-adjustable height. Background Art

[0002] Manhole covers can be seen everywhere on the road. Manhole covers are divided into many categories. Although the structures are similar (except for the initial rainwater manhole covers), the other sewer manhole covers, cable manhole covers, etc. are all large circular structures. In the past, many manhole covers were preset on the car lanes, but now many are designed in the middle of the green belts, or in the non-motorized vehicle lanes. There are also manhole covers on the green belts next to many bus stops. The existing manhole cover design position makes it very likely that pedestrians will step on the manhole covers, and whether it is now or in the past, the manhole cover openings are preset positions, so the manhole cover openings often appear at a height lower than the road surface. After the manhole cover is installed, the manhole cover and the road surface will be inconsistent in height, which will easily cause water accumulation on rainy days and cause the road surface to be uneven, which also greatly affects the appearance. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the prior art, thereby providing a manhole cover with fine-adjustable height, which makes the manhole cover basically consistent with the road surface height and has better safety.

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions:

[0005] The utility model discloses a manhole cover with fine-adjustable height, comprising a manhole cover and a manhole seat matched with the manhole cover; the manhole seat is divided into an inner wall and an outer wall which can be adjusted up and down; the outer wall is a hollow structure, the inner wall is located inside the outer wall, can move up and down inside the outer wall, and one end can move to the top of the outer wall.

[0006] Preferably, three windows are evenly arranged on the inner side wall of the outer wall, through which the inner wall can be seen.

[0007] Preferably, two vertically arranged bayonet holes are provided on the side of the window for fixing the inner wall at different heights.

[0008] Preferably, three clamping columns are evenly arranged on the inner wall.

[0009] Preferably, handles are evenly arranged on the inner wall.

[0010] Preferably, a removable wire mesh is provided at the lower end of the well seat.

[0011] The beneficial effects of the utility model are:

[0012] The manhole seat wall is designed as an outer wall and an outer wall with adjustable height. In this way, when the pre-buried manhole seat mouth is low, the inner wall can be raised so that the manhole cover can be kept at the same height as much as possible with the ground after placement. At the same time, fill can be carried out around the inner wall of the height to keep the ground at a basically consistent height, which will not cause water accumulation and will also be more beautiful and flat. The wire mesh design can block fallen debris from falling into the well when problems occur with the manhole cover, such as when the manhole cover is moved. It also ensures that children and pedestrians will not fall into the well, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0014] Figure 1 , 2 4 is a schematic diagram of the structure of the utility model;

[0015] Figure 3 , 5 It is a partially enlarged schematic diagram of the utility model.

[0016] In the figure: 1-well cover, 2-well seat, 3-wire mesh, 2.1-well ring, 2.2-inner wall, 2.3-outer wall, 2.4-window, 2.5-handle, 2.6-stud, 2.7-bayonet DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] like Figure 1-5As shown, a manhole cover with fine-adjustable height is mainly used for manhole covers on cable wells in green belts. It includes a manhole cover 1 and a manhole seat 2 matched with the manhole cover 1; the manhole seat 2 is divided into an inner wall 2.2 and an outer wall 2.3 that can be adjusted up and down; the outer wall 2.3 is a hollow structure, the inner wall 2.2 is located inside the outer wall 2.3, and can move up and down inside the outer wall 2.3, and one end can be moved to the top of the outer wall 2.3; because the green belt is not at the same height, the manhole cover on the green belt is easy to be lower than the green belt, which will cause a part of the manhole cover to be concave. If the manhole cover happens to be next to the bus stop, everyone will walk to the green belt. , and the unevenness of the manhole cover makes it easy to trip, and when it rains heavily, the lower position of the manhole cover will also cause water accumulation; further, the inner wall 2.2 is located inside the outer wall 2.3, and can be lifted upward along the outer wall 2.3. When it is completely flat, the upper end surfaces of the inner wall 2.2 and the outer wall 2.3 are located in the same plane, and the manhole cover 1 is placed on the inner wall 2.2. When the inner wall 2.2 rises, the height of the manhole cover 1 from the well seat 2 will also increase, and the well seat 2 is fixed on the ground. Therefore, the distance between the manhole cover 1 and the ground will change as the inner wall 2.2 rises.

[0019] Three windows 2.4 are evenly arranged on the inner side wall of the outer wall 2.3, through which the inner wall 2.2 can be seen.

[0020] Two vertically arranged bayonet holes 2.7 are provided on the side of the window 2.4 for fixing the inner wall 2.2 at different heights.

[0021] Three clamping columns 2.6 are evenly arranged on the inner wall 2.2. Specifically, the clamping columns 2.6 are arranged corresponding to the windows 2.4. A clamping column 2.6 is arranged on the inner wall 2.2 at each window 2.4. After the clamping column 2.6 is inserted into the clamping port 2.7, the inner wall 2.2 can be adjusted to different heights.

[0022] The inner wall 2.2 is also evenly provided with handles 2.5. Specifically, the handles 2.5 are located in the window 2.4. When the height of the inner wall 2.2 is to be adjusted, the height of the inner wall 2.2 can be adjusted by grasping any two handles 2.5 and pulling them upwards, and then inserting the clamping column 2.6 into the clamping hole 2.7. In this way, the height of the inner wall 2.2 can be adjusted. In this way, when the preset well seat position is lower than the ground height, the position of the manhole cover 1 can be raised by adjusting the height of the inner wall 2.2, so that the manhole cover 1 can be kept at a basically consistent height with the ground.

[0023] A removable wire mesh 3 is provided at the lower end of the well seat 2; specifically, if the well cover 1 moves, the wire mesh 3 can not only prevent debris from falling into the well, but also play a protective role to prevent children and pedestrians from accidentally falling.

[0024] The beneficial effects of the utility model are:

[0025] The manhole seat wall is designed as an outer wall and an outer wall with adjustable height. In this way, when the pre-buried manhole seat mouth is low, the inner wall can be raised so that the manhole cover can be kept at the same height as much as possible with the ground after placement. At the same time, fill can be carried out around the inner wall of the height to keep the ground at a basically consistent height, which will not cause water accumulation and will also be more beautiful and flat. The wire mesh design can block fallen debris from falling into the well when problems occur with the manhole cover, such as when the manhole cover is moved. It also ensures that children and pedestrians will not fall into the well, thereby improving safety.
