Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in fig. 1-11, the invisible well lid comprises a bottom frame 1, a tray 2, an original well lid 3, a pavement layer 4 and an anti-blocking opening device.

The tray 2 is square dish, and the bottom is equipped with strengthening rib 11, and the layer 4 of mating formation is laid in the tray 2 through strengthening rib 11. The bottom frame 1 is fixedly sleeved on the periphery of the tray 2, and the bottom frame 1 is welded with the tray 2. The construction method comprises the following steps: the bottom frame 1 is welded with the tray 2 and placed above the original well cover 3, and then the pavement layer 4 is paved in the tray 2 and is paved to be flush with the surrounding pavement. By providing the bottom frame 1 at the outer frame of the tray 2, the strength and rigidity of the tray 2 can be increased.

The anti-blocking opening device is fixed at the center of the tray 2 by welding with the reinforcing ribs 11. The anti-blocking opening device comprises a vertical pipe 5, a stop block 6, an anti-blocking block 8, a slide bar 7 and a lifting block 9. The stopper 6 is welded to the top end of the vertical tube 5 and is welded coaxially with the vertical tube 5. The upper center of the stop block 6 is provided with an embedded groove 61 matched with the anti-blocking block 8, the lower center of the stop block 6 is provided with a slide bar through hole 62 matched with the slide bar 7, the embedded groove 61 and the slide bar through hole 62 are communicated up and down and penetrate through the whole stop block 6, and the inner size of the slide bar through hole 62 is smaller than the inner size of the embedded groove 61. The anti-blocking block 8 is welded at the top end of the sliding rod 7, a bolt hole 71 is formed in the center of the bottom of the sliding rod 7, a through hole 92 opposite to the bolt hole 71 is formed in the center of the lifting block 9, and the lifting block 9 is fixed at the bottom of the sliding rod 7 through a bolt 10. The outer dimension of the lifting block 9 is larger than the slide bar through hole 62. The slide bar 7 can slide up and down between the embedded groove 61 and the slide bar through hole 62, and the anti-blocking block 8 and the lifting block 9 play a limiting role on the slide bar 7. When in use, the sliding rod 7 is inserted from the sliding rod through hole 62 from top to bottom, then the lower end of the sliding rod 7 is inserted into the square hole 91 of the lifting block 9, and then the lifting block 9 is connected with the sliding rod 7 by using the bolt 10 to pass through the through hole 92 and the bolt hole 71.

The anti-blocking block 8 is made of a magnetic material, and the use method of the anti-blocking opening device is demonstrated: when the hidden well lid is required to be opened, an operator uses a magnet to attract the anti-blocking block 8 and lifts the anti-blocking block 8 out of the embedded groove 61, meanwhile, the sliding rod 7 ascends along the sliding rod through hole 62 and ascends until the lifting block 9 abuts against the stop block 6, and the operator continues to apply a drawing acting force on the sliding rod 7 and the anti-blocking block 8, so that the whole hidden well lid can be lifted. When the invisible well lid is covered on the original well lid 3, under the action of gravity, the sliding rod 7 moves downwards to the anti-blocking block 8 to be embedded into the embedded groove 61 and block the embedded groove 61, so that the functions of dust accumulation prevention and blocking prevention can be achieved. The setting of anti-blocking opening device, when needs open stealthy well lid, only need pull up prevent that the jam piece 8 can, when not opening, prevent that the jam piece 8 embedding is inlayed and is inlayed groove 61 and shutoff is inlayed groove 61, make rainwater, dust and rubbish can not get into, play the effect of rain-proof water, dust and rubbish, consequently, this stealthy well lid does not need operating personnel to spend time to draw the deposit in the lifting hole clearly, and the opening of well lid is more convenient, and because can not pile up rubbish, so be difficult to send the putrefactive odor.

As a preferable scheme, the sliding rod 7 is designed as a square rod, the sliding rod through hole 62 is designed as a square through hole, the embedded groove 61 is a circular groove, the anti-blocking block 8 is a cylindrical block, the lifting block 9 is a square block, and the inner hole of the vertical pipe 5 is a square hole. The slide bar 7 and the slide bar through hole 62 are designed to be square, so that the slide bar 7 can be prevented from rotating when the invisible well lid is pulled out, and the shaking of the invisible well lid caused by the rotation of the slide bar 7 is avoided. The lifting block 9 is designed as a square block, and the inner hole of the vertical pipe 5 is designed as a square hole, so that the function of preventing the sliding rod 7 from rotating is also achieved.

As a preferable scheme, a positioning protrusion 64 and a positioning groove 93 which are opposite up and down are respectively arranged on the contact surface of the stop block 6 and the vertical pipe 5; the opposite surfaces of the stop block 6 and the lifting block 9 are also provided with a positioning protrusion 64 and a positioning groove 93 which are opposite to each other vertically. The setting of location arch 64 and positioning groove 93 can increase dog 6 and vertical pipe 5, and lift by crane piece 9 and dog 6's area of contact when lifting by crane tray 2, reduces the pressure that lift by crane piece 9 and dog 6 bore when opening stealthy well lid to reduce and lift by crane piece 9 and dog 6 take place cracked probability in tray 2 the in-process of lifting by crane.

Preferably, the groove bottom of the embedded groove 61 is provided with two circles of annular protrusions 63, and the bottom surface of the anti-blocking block 8 is provided with two circles of annular grooves 81 which can be engaged with the annular protrusions 63. After the anti-blocking block 8 is embedded into the embedded groove 61, the annular protrusion 63 and the annular groove 81 can seal the contact surface of the anti-blocking block 8 and the embedded groove 61, so that dust, rainwater and the like are prevented from entering and accumulating along a gap between the anti-blocking block 8 and the stop block 6, and the anti-blocking block 8 is prevented from being difficult to pull out. After passing through the gap between the outer side wall of the anti-blocking block 8 and the groove wall of the embedded groove 61, the rainwater reaches the gap between the bottom wall of the anti-blocking block 8 and the groove bottom of the embedded groove 61, and then the rainwater can reach the slide bar through hole 62 only after passing through the gap between the annular bulge 63 of the outer ring and the groove wall of the annular groove 81. The outer ring annular protrusion 63 blocks rainwater, so that the rainwater cannot easily reach the slide bar through hole 62, a certain waterproof sealing effect is achieved, and meanwhile, odor in a sewer can be prevented from escaping through the slide bar through hole 62 to influence the surrounding environment. The anti-blocking block 8 can be adhered with a rubber sleeve, the rubber sleeve is also embedded in the embedded groove 61, the rubber sleeve not only can play a role in sealing a gap between the block 8 and the embedded groove 61, but also can play a role in preventing water, and the corrosion time of the anti-blocking block 8 is prolonged.

Alternatively, the anti-blocking block 8 is made of stainless steel, the top surface is provided with a mounting hole, the mounting hole is screwed or bonded with a weak magnet, and the orifice of the mounting hole is blocked by rubber leather. When the anti-blocking block 8 needs to be lifted, the iron pry bar is used for adsorbing the weak magnet on the anti-blocking block 8, and then the iron pry bar is lifted, so that the anti-blocking block 8 can be lifted from the embedded groove 61.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
