DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0038] Specifically, if Figure 1-Figure 7 As shown, a manhole cover fixing device is provided in the present application, which is mainly used to solve the problem that the existing manhole cover 500 is difficult to carry. The manhole cover 500 is mainly used in conjunction with a fixing ring 100, a manhole cover ring 200 and a fixing ring 300.

[0039] Its specific structure is:

[0040] The fixing ring 100 is an integral ring body. The fixing ring 100 is installed on the foundation when the manhole is built, or is processed when the manhole is repaired. The fixing ring 100 is provided with an inner cavity 110 and a fixing groove 120. The inner cavity 110 is used to install the manhole cover 500, and the fixing groove 120 fixes the manhole cover 500. The fixing groove 120 is connected to the inner cavity 110 to facilitate the fixation of the manhole cover 500. One side of the fixing groove 120 is opened. There is a limiting groove 130, which is connected to the fixing groove 120. Since the existing manhole cover 500 has no corresponding structure to be used in conjunction with the limiting groove 130, in order to avoid this situation in the embodiment of the present application, a manhole cover ring 200 is sleeved on the manhole cover 500. The outer diameter of the manhole cover ring 200 is equal to the inner diameter of the fixing ring 100. The manhole cover ring 200 is clamped with the manhole cover 500, so that the manhole cover ring 200 is not easy to fall off the manhole cover 500.

[0041] Among them, a fixing part 210 is provided on the outer position of the manhole cover ring 200. In this application, the fixing part 210 is a fixing pin, and the number and position of the fixing pins correspond one-to-one to the number and position of the fixing grooves 120, so that when the manhole cover ring 200 is installed on the fixing ring 100, the fixing pin can cooperate with the fixing groove 120, so that the fixing pin is located in the fixing groove 120. Since a limiting groove 130 is provided on one side of the fixing groove 120, when the fixing pin is located in the fixing groove 120, the manhole cover 500 is rotated horizontally so that the fixing pin moves to the limiting groove 130, thereby completing the fixation of the manhole cover 500.

[0042] In order to prevent the manhole cover 500 from shaking, the width and depth of the limiting groove 130 correspond to the size of the fixing pin, so that the fixing pin is fixed in the limiting groove 130 to prevent the manhole cover 500 from shaking horizontally.

[0043] On the basis of the above structure, due to the presence of the fixing groove 120, the fixing pin may move within the fixing groove 120. To avoid this situation, an adjusting member 400 is provided in the embodiment of the present application. The adjusting member 400 mainly functions to prevent the fixing pin from moving from the limiting groove 130 into the fixing groove 120. The specific implementation process is as follows:

[0044] The main body of the adjusting member 400 is provided with a fixing bolt 410, and an adjusting block 420 is sleeved on the fixing screw bolt, and the adjusting block 420 is threadedly connected to the fixing bolt 410, so that the adjusting block 420 moves on the fixing bolt 410 along the direction of the fixing bolt 410.

[0045] A connecting rod 430 is provided on the adjustment block 420 . The connecting rod 430 is a movable rod. The main function of the connecting rod 430 is to abut and limit the fixing pin to prevent the fixing pin from moving from the limiting groove 130 to the fixing groove 120 .

[0046] In the embodiment of the present application, the connecting rod 430 is composed of a first adjusting rod 431 and a second adjusting rod 432. The first adjusting rod 431 and the second adjusting rod 432 are rotatably connected through a rotating shaft to enable the first adjusting rod 431 and the second adjusting rod 432 to rotate relative to each other. At the same time, the rotating shaft also forms an abutment portion 433, and the abutment portion 433 mainly abuts against the fixing pin, so that the fixing pin is limited and fixed.

[0047] One end of the first adjusting rod 431 away from the abutting portion 433 abuts against the adjusting block 420 .

[0048] In order to realize the abutting relationship of the connecting rod 430, it is necessary to push the connecting rod 430 so that the first adjusting rod 431 and the second adjusting rod 432 rotate with each other. The adjusting block 420 is provided with a first block 421 and a second block 422, and the first block 421 and the second block 422 are rotatably connected. Figure 7 As shown, the cooperation between the rotating groove 424 and the rotating block 425 allows the first block 421 and the second block 422 to rotate with each other without separating, wherein the positions corresponding to the fixing bolts 410 are provided with through grooves 423, the through grooves 423 on the first block 421 are threadedly connected to the fixing bolts 410, and the through grooves 423 on the second block 422 are used for the fixing bolts 410 to pass through. Under this structure, when the first block 421 rotates on the fixing bolt 410, the second block 422 does not rotate and is restricted by the connecting rod 430, so that when the first block 421 moves up and down on the fixing bolt 410, the second block 422 drives the first adjusting rod 431 and the second adjusting rod 432 to rotate with each other, so as to facilitate the abutment part 433 to abut against the fixing pin.

[0049] In the embodiment of the present application, since the space of the fixed groove 120 is small, when the first adjusting rod 431 and the second adjusting rod 432 are directly rotated, the abutment portion 433 will abut against the inner wall of the fixed groove 120, affecting the adjustment process of the adjustment block 420. To avoid this situation, the end of the second adjusting rod 432 away from the abutment portion 433 is slidably connected to the slide 440, and the slide 440 abuts against the fixed groove 120.

[0050] like Figure 6 As shown, more specifically, the slide 440 is a contact block, which is fixedly connected to the fixing bolt 410, so that the fixing bolt 410 is in contact with the fixing groove 120 through the contact block; a first slide groove 441 is provided on the abutment block, and the end of the second adjustment rod 432 away from the abutment portion 433 is slidingly connected to the first slide groove 441, so that when the adjustment block 420 is adjusted on the fixing bolt 410, the adjustment block 420 drives the connection rod 430 to rotate itself, and the second adjustment rod 432 slides in the first slide groove 441.

[0051] On the basis of the above structure, in order to achieve effective abutment of the abutment portion 433 against the fixed pin, a stopper 450 is also rotatably connected to the abutment portion 433. The area of the side of the stopper 450 facing the limiting groove 130 is smaller than the cross-sectional area of the limiting groove 130, so that the stopper can effectively abut the fixed pin. To facilitate the abutment process of the stopper 450 against the fixed pin, a second sliding groove 451 is provided on the stopper 450 at a position corresponding to the abutment portion 433, and the abutment portion 433 is slidably connected in the second sliding groove 451.

[0052] When the adjusting block 420 is adjusted on the fixing bolt 410 , the abutting portion 433 is located in the limiting groove 130 .

[0053] In the embodiment of the present application, a fixing hole 310 is provided on the fixing ring 300 at a position corresponding to the adjusting member 400 , and a fixing bolt 410 on the adjusting member 400 is connected to the fixing hole 310 correspondingly so that the fixing bolt 410 is fixed in the fixing hole 310 .

[0054] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
