Description

Technical Field

[0001] The utility model belongs to the technical field of manhole covers, and particularly relates to a glue-free noise-proof adjustable manhole cover. Background Technique

[0002] With the acceleration of the urbanization pace in China, the municipal infrastructure, especially the urban road construction, has developed rapidly, and the manhole cover is an important part of the municipal facilities.

[0003] Traditionally, when the manhole cover is placed on the manhole ring, a rubber ring needs to be added between the manhole cover and the manhole ring to prevent iron from rubbing against iron and making abnormal noises. However, with long-term use, the rubber ring will be severely worn, which easily causes a large gap between the manhole cover and the manhole ring, resulting in the manhole cover shaking when pressed, and thus generating a large amount of noise. Therefore, we have proposed a glue-free noise-proof adjustable manhole cover. Content of the Utility Model

[0004] The purpose of the utility model is to provide a glue-free noise-proof adjustable manhole cover. By setting a placement ring, specifically, the width of the placement ring on the manhole ring and the width of the bearing contact surface of the manhole cover are increased to mm to improve stability. The top of the placement ring is the bearing surface. By precisely machining the high-precision conical surface one and the high-precision conical surface two to the precise fit dimensions, the gap is reduced, thereby achieving the effect of tight fitting, so that the manhole cover will not shake strongly, and the sound can be eliminated without placing a rubber ring, solving the problem that there is a large gap between the existing manhole cover and the manhole ring, which will cause the manhole cover to shake when pressed, and thus generate a large amount of noise.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a glue-free noise-proof adjustable manhole cover, including a manhole ring. A manhole cover is arranged inside the manhole ring. A hexagonal reinforcing plate is fixedly connected to the center of the bottom of the manhole cover. Reinforcing plates are fixedly connected to the six corners on the outside of the hexagonal reinforcing plate. A high-precision conical surface one is arranged on the outer surface of the manhole cover;

[0007] A high-precision conical surface two is opened on the inner wall of the manhole ring. A placement ring is fixedly connected to the surface of the high-precision conical surface two. Three card seats are fixedly connected to the outer surface of the placement ring. The three card seats are arranged in a circumferential array. The surface of the high-precision conical surface one is in contact with the surface of the high-precision conical surface two. By setting a placement ring, specifically, the width of the placement ring on the manhole ring and the width of the bearing contact surface of the manhole cover are increased to mm to improve stability. The top of the placement ring is the bearing surface. By precisely machining the high-precision conical surface one and the high-precision conical surface two to the precise fit dimensions, the gap is reduced, thereby achieving the effect of tight fitting, so that the manhole cover will not shake strongly, and the sound can be eliminated without placing a rubber ring.

[0008] Further, a clamping block is fixedly connected to the bottom of the reinforcing plate. A tapered groove is formed on the outer side of the clamping block. The surface of the tapered groove contacts the inner ring of the placement ring. The top of the reinforcing plate is fixedly connected to the bottom of the manhole cover. The clamping block on the reinforcing plate contacts the inner ring of the placement ring through the tapered groove, and can be closely fitted again to improve the stability.

[0009] Further, a stabilizing assembly is arranged below the hexagonal reinforcing plate. The stabilizing assembly includes stabilizing plates. The number of the stabilizing plates is six. The six stabilizing plates are arranged in a circumferential array. The parts connected by the six stabilizing plates are the same. A fixing ring is fixedly connected to the inner wall of the placement ring. Six inclined blocks are fixedly connected to the inner wall of the hexagonal reinforcing plate. One side of each of the six inclined blocks corresponding to the six stabilizing plates is provided with an inclined surface. A plurality of convex blocks are fixedly connected to the corresponding sides of the stabilizing plates and the inclined blocks. By arranging the stabilizing assembly, specifically, after the manhole cover and the manhole ring are matched, the inclined blocks in the hexagonal reinforcing plate are inserted into the stabilizing plates. Then, the stabilizing plates and the inclined blocks increase the friction force through the convex blocks on the surfaces, improve the stability after the manhole cover is installed, reduce the situation of shaking again, and thus improve the sound insulation effect.

[0010] Further, a support rod is fixedly connected to the side of the stabilizing plate close to the fixing ring. The side of the support rod away from the stabilizing plate is fixedly connected to the inner ring of the fixing ring. The support rod is used to support the stabilizing plate. Since the bottom of the inclined block and the top of the stabilizing plate are both provided with inclined surfaces, the two can be smoothly inserted.

[0011] Further, three elastic arms are fixedly connected to the bottom of the reinforcing plate. The three elastic arms are arranged in a circumferential array. The parts connected by the three elastic arms are the same. A buckle is fixedly connected to the side of the elastic arm close to the placement ring. A hinge is fixedly connected to the back of the manhole cover. The top and bottom of the buckle are both provided with inclined surfaces. The top and bottom of the clamping seat are both provided with inclined surfaces. The surface of the buckle contacts the surface of the clamping seat. Since the bottom of the buckle and the top of the clamping seat are both provided with inclined surfaces, after the buckle contacts the clamping seat, the buckle will be squeezed, and then the elastic arm will be squeezed and bent, so that the buckle can smoothly pass through the clamping seat.

[0012] The utility model has the following beneficial effects:

[0013] 1. By arranging the placement ring, specifically, the width of the placement ring on the manhole ring and the width of the bearing contact surface of the manhole cover are increased to 30 mm to increase the stability. The top of the placement ring is the bearing surface. By precisely machining the high-precision conical surface one and the high-precision conical surface two to the precision fit dimensions, the gap is reduced, so as to achieve the effect of close fitting, so that the manhole cover will not shake strongly, and the sound can be removed without placing a rubber ring.

[0014] 2. The utility model improves the stability after the manhole cover is installed and further reduces the shaking situation by setting a stabilizing component. Specifically, after the manhole cover and the manhole ring are matched, the inclined block in the hexagonal reinforcing plate will be inserted into the stabilizing plate, and the stabilizing plate and the inclined block will increase the friction force through the bumps on the surface, thereby improving the sound insulation effect.

[0015] Of course, any product implementing the utility model does not necessarily need to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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.

[0026] Please refer to Figures 1-6 As shown, the present utility model is a glue - free noise - proof adjustable manhole cover, which includes a manhole ring 1. Inside the manhole ring 1, there is a manhole cover 11. At the center of the bottom of the manhole cover 11, a hexagonal reinforcement plate 114 is fixedly connected. On the outer hexagons of the hexagonal reinforcement plate 114, reinforcement plates 111 are fixedly connected. On the outer surface of the manhole cover 11, there is a high - precision conical surface 113.

[0027] On the inner wall of the manhole ring 1, there is a high - precision conical surface 13. On the surface of the high - precision conical surface 13, a placement ring 131 is fixedly connected. On the outer surface of the placement ring 131, three card seats 132 are fixedly connected. The three card seats 132 are arranged in a circumferential array. The surface of the high - precision conical surface 113 contacts the surface of the high - precision conical surface 13. By setting the placement ring 131, specifically, the width of the placement ring 131 on the manhole ring 1 and the width of the bearing contact surface of the manhole cover 11 are increased to 30 mm to increase stability. The top of the placement ring 131 is the bearing surface. By precisely machining the high - precision conical surface 113 and the high - precision conical surface 13 to the precision - fitting dimensions, the gap is reduced, so as to achieve the effect of close fitting, so that the manhole cover 11 will not have strong shaking and can play the role of removing sound without placing a rubber ring.

[0028] At the bottom of the reinforcement plate 111, a block 112 is fixedly connected. On the outer side of the block 112, a tapered groove 21 is opened. The surface of the tapered groove 21 contacts the inner ring of the placement ring 131. The top of the reinforcement plate 111 is fixedly connected to the bottom of the manhole cover 11.

[0029] Below the hexagonal reinforcement plate 114, a stabilizing component 12 is provided. The stabilizing component 12 includes a stabilizing plate 121. The number of the stabilizing plates 121 is six. The six stabilizing plates 121 are arranged in a circumferential array. The parts connected by the six stabilizing plates 121 are the same. A fixing ring 122 is fixedly connected to the inner wall of the placement ring 131. Six inclined blocks 123 are fixedly connected to the inner wall of the hexagonal reinforcement plate 114. On the sides corresponding to the six stabilizing plates 121, the six inclined blocks 123 are all provided with inclined surfaces. On the corresponding sides of the stabilizing plate 121 and the inclined block 123, a number of convex blocks are fixedly connected. By setting the stabilizing component 12, specifically, after the manhole cover 11 and the manhole ring 1 are matched, the inclined blocks 123 in the hexagonal reinforcement plate 114 will be inserted into the stabilizing plates 121. Then, the stabilizing plates 121 and the inclined blocks 123 will increase the friction force through the convex blocks on the surface, improve the stability of the manhole cover 11 after installation, and reduce the situation of shaking again, so as to improve the sound - proof effect.

[0030] One side of the stabilizing plate 121 close to the fixing ring 122 is fixedly connected with a support rod 124, and one side of the support rod 124 away from the stabilizing plate 121 is fixedly connected with the inner ring of the fixing ring 122.

[0031] The bottom of the reinforcing plate 111 is fixedly connected with elastic arms 14. The number of the elastic arms 14 is three. The three elastic arms 14 are arranged in a circumferential array. The parts connected by the three elastic arms 14 are the same. One side of the elastic arm 14 close to the placing ring 131 is fixedly connected with a buckle 141. The back of the manhole cover 11 is fixedly connected with a hinge 15. The top and bottom of the buckle 141 are both beveled. The top and bottom of the clamping seat 132 are both beveled. The surface of the buckle 141 is in contact with the surface of the clamping seat 132.

[0032] A specific application of this embodiment is:

[0033] During use, cover the manhole cover 11 on the well ring 1 through the hinge 15. Then, the manhole cover 11 will cooperate with the high-precision second conical surface 13 on the inner wall of the well ring 1 through the high-precision first conical surface 113. By removing the rubber strip, the width of the placing ring 131 on the well ring 1 and the width of the bearing contact surface of the manhole cover 11 are increased to 30 mm to increase the stability. The top of the placing ring 131 is the bearing surface. By using precision machining of the high-precision first conical surface 113 and the high-precision second conical surface 13 to the precision fit size, the gap is reduced, so as to achieve the effect of close fitting, so that the manhole cover 11 will not shake strongly, and the rubber ring does not need to be placed to remove the sound. At the same time, the clamping block 112 on the reinforcing plate 111 will contact the inner ring of the placing ring 131 through the conical groove 21, and can be closely fitted again to improve the stability. At the same time, since the bottom of the buckle 141 and the top of the clamping seat 132 are both beveled, after the buckle 141 contacts the clamping seat 132, the buckle 141 will be squeezed, and then the elastic arm 14 will be squeezed and bent, so that the buckle 141 can pass through the clamping seat 132 smoothly. Then, under the elastic action of the elastic arm 14, the buckle 141 is reset, and the buckle 141 is fitted and clamped with the clamping seat 132 to play a fixing role. Then, the inclined block 123 in the hexagonal reinforcing plate 114 will be inserted into the stabilizing plate 121. Since the bottom of the inclined block 123 and the top of the stabilizing plate 121 are both beveled, the two can be inserted smoothly. Then, the stabilizing plate 121 and the inclined block 123 will increase the friction force through the bumps on the surface, improve the stability after the manhole cover 11 is installed, and reduce the shaking situation again, so as to improve the sound insulation effect.
