Description
Technical field
The utility model is related to telecommunications maintenance facility field, more particularly to a kind of maintenance well lids.
Background technology
With the development of China's urban construction, underground communication gauze is more and more intensive, the corresponding mating inspection of the thing followed
The setting for looking into well is also more and more.Now well lid being often used to be fixed on well head, contact surface is to contact firmly, and damping performance is poor,
When well lid is rolled by vehicle, well lid is mutually collided with well seat, generates strenuous vibration and high-decibel noise, affects people's life
It is living.
Utility model content
The purpose of this utility model is to provide a kind of maintenance well lids, by the way that damping is arranged in well seat inner circumferential,
Damping absorbs the pressure that well lid is subject to, the advantages of having and weaken the vibrations that well lid is subject to, reduce noise.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of maintenance well lid, packet
Well seat is included, well lid is placed on the inside of the pedestal, the seat slot coordinated with well lid, the seat slot side week are offered on the well seat
To several square grooves along seat slot radial direction are evenly equipped with, it is embedded with the snubber block moved along square groove length direction in the square groove,
The end that the snubber block stretches out square groove offers axis horizontal and the arc notch higher than snubber block, the snubber block side of stretching into
The end of slot, which contradicts, spring of the axis along square groove length direction.
By using above-mentioned technical proposal, by well lid buckle closure in seat slot, well lid is contradicted with arc notch and is compressed, and well lid pushes away
To after mobile a distance inside square groove, snubber block compressed spring, spring generates reaction and squeezes snubber block, damping dynamic snubber block
When block is equal to the gravity of well lid to the resultant force that well lid generates, well lid is stablized in seat slot.When vehicle is pressed on well lid, snubber block edge
Square groove length direction moves, further compressed spring, until the resultant force that spring makes snubber block generate the pressure of snubber block is equal to
In pressure or snubber block the indentation square groove that well lid acts on snubber block, well lid end face directed downwardly is contradicted with seat slot bottom surface, and realization subtracts
Shake damping of the block to maintenance well lid.Well lid is arcuate structure with snubber block contact surface so that when well lid moves down small distance,
Snubber block generates the longer displacement distance along seat slot axis direction, to make spring generate preferable damping effect.
The utility model is further arranged to：The seat slot bottom surface is provided with the gasket groove of circular ring type structure, the gasket groove
Inside it is embedded with rubber washer.
By using above-mentioned technical proposal, when well lid end face directed downwardly and the conflict of seat slot bottom surface, well lid end face directed downwardly
With rubber washer impact absorption, noise and damage that well lid is generated with the collision of seat slot bottom surface are reduced.
The utility model is further arranged to：The guide rod for being fixed on snubber block, the guiding are arranged in the spring
Bar is arranged in be fixed in square groove deviates from the block that snubber block one end contradicts with spring.
By using above-mentioned technical proposal, when well lid squeezes snubber block, snubber block pushes guide rod to be moved in square groove, subtracts
Compressed spring in block moving process is shaken, spring is made to provide the elastic acting force along snubber block moving direction, realization subtracts well lid
Shake.The elastic force direction of the generation of guide rod guide springs keeps its holding identical as the snubber block direction of motion, reaches preferable damping
Effect.
The utility model is further arranged to：The block lower end is installed with the screw rod for being pierced by well seat.
It by using above-mentioned technical proposal, is connect with block using screw rod, fixed form is simple, and cost is relatively low, assembly effect
Rate is high.
The utility model is further arranged to：The six square nuts compressed with well seat, the square groove are installed on the screw rod
Short transverse bottom surface offers below guide rod and the slot hole of width and screw rod cooperation.
By using above-mentioned technical proposal, behind slot hole length direction mobile screw position, using six square nuts by screw rod
It is fixed, the adjusting of stop location is realized, damping effect is enable to be adjusted by different use environments, reaches preferable effect.
The utility model is further arranged to：Well seat bottom surface offers the recessing groove for accommodating screw rod and six square nuts.
By using above-mentioned technical proposal, screw rod and six square nuts are set in well seat, when carrying out the installation of well seat,
The slot for placing screw rod and six square nuts need not be additionally opened up on well seat mounting surface, be convenient for the installation of well seat.
The utility model is further arranged to：The end face of the well lid towards seat slot bottom surface is provided with rounded corner.
By using above-mentioned technical proposal, when the setting of rounded corner makes well lid mutually be moved with snubber block, snubber block and well
Abrasion between lid edge is smaller, extends the service life of maintenance well lid.
The utility model is further arranged to：Square groove short transverse bottom surface offers chord length and is equal to snubber block width one
Half rhone, the rhone is along square groove length direction.
By using above-mentioned technical proposal, rhone can make to enter the water outflow in square groove, reduce sewage to spring
Corrosion is conducive to extend the service life of maintenance well lid.
In conclusion the utility model has the advantages that：By well lid buckle closure in seat slot, well lid and arc notch
It contradicts and compresses, well lid pushes snubber block to mobile one end inside square groove after, and snubber block compressed spring, spring generates reaction
Snubber block is squeezed, when snubber block is equal to the gravity of well lid to the resultant force that well lid generates, well lid is stablized in seat slot.When people or vehicle
When being pressed on well lid, snubber block is moved along square groove length direction, further compressed spring, until spring makes the pressure of snubber block
The resultant force that snubber block generates is equal to pressure of the well lid to snubber block；Or in snubber block indentation square groove, well lid end face directed downwardly and seat
Groove bottom contradicts, and realizes damping of the snubber block to maintenance well lid.Well lid and snubber block contact surface are arcuate structure so that well lid to
When lower mobile small distance, snubber block generates the longer displacement distance along seat slot axis direction, preferable to make spring generate
Damping effect.
