Abstract
The utility model discloses a kind of filter cylinder access panels for deduster, the access panel cooperated including manhole and the manhole, the access panel is equipped with the step that sealing is matched with manhole, the side of the step is circumferentially uniformly arranged several blind holes, the bottom edge of the blind hole is flushed with the bottom surface of the step, the damping block along the sliding of blind hole length direction is embedded in the blind hole, the end that the damping block stretches out blind hole is equipped with arc slope, the central angle of the arc slope is 60 ° -90 °, the end of the damping block insertion blind hole is equipped with the spring along blind hole length direction.Damping block is arranged in the access panel step side of the utility model, makes have certain buffering between air filter housing and access panel, simple and reasonable, have good damping noise reduction effect.
Description
Technical field
The utility model relates to air filter technical fields, and in particular to a kind of filter cylinder access cover for deduster
Plate.
Background technique
Currently, integrally disposed several filter cores in air filter shell, hull outside sealing, only in filter core cylinder position
Equipped with manhole, to be overhauled and to be replaced to filter core, it is equipped with access panel at manhole, at access panel and manhole
Shell directly contacts, and with the operation of air filter, resonance, longtime running occur for shell and access panel, and access panel holds
It easily loosens, is hit between shell and cover board, generate high-decibel noise, the consumption experience of consumer is poor.
Utility model content
The purpose of this utility model is that overcome defect existing in the prior art, provide that a kind of structure is simple, reduces and makes an uproar
Sound reduces the filter cylinder access panel for deduster of resonance.
To achieve the above object, the technical solution of the utility model is to design a kind of filter cylinder access cover for deduster
Plate, including the access panel that manhole and the manhole cooperate, the access panel is equipped with and matches sealing with manhole
Step, the side of the step is circumferentially uniformly arranged several blind holes, and the bottom edge of the blind hole is flushed with the bottom surface of the step,
The damping block along the sliding of blind hole length direction is embedded in the blind hole, the end that the damping block stretches out blind hole is equipped with circular arc slope
Face, the central angle of the arc slope are 60 ° -90 °, and the end of the damping block insertion blind hole is equipped with along blind hole length direction
Spring.
Access panel is cooperated into buckle closure in manhole, on the edge and cover board of shell manhole by step and manhole
Arc slope damping block contradict and compress, manhole edge pushes damping block to after blind hole internal slide a distance, subtracts
Block compressed spring is shaken, spring generates reaction force and squeezes damping block, and the sealing reached between shell manhole and access panel is steady
It is fixed.The shell vibrating when air filter operation, damping block are moved along blind hole length direction, further compressed spring, spring pair
The pressure of thrust and shell vibrating that damping block generates is cancelled out each other, and realizes damping of the damping block to shell vibrating.
Preferred technical solution is that the bottom surface of the step and manhole cooperation offers the seal groove of circular ring shape, described
O-shaped rubber seal is equipped in seal groove.When the bottom surface of access panel and step contradicts, housing parts around manhole with
Rubber washer impact absorption, reduces noise and the damage of cover board and shell collision generation, while also having sealing function, avoids
Outer dust is isolated in by filtering outside filtering element for air filter to escape.
Preferred technical solution is that the chord length of the arc slope is greater than the width of the blind hole.The chord length of arc slope
Greater than the width of blind hole, avoid that damping block being pressed into blind hole when shell vibrating.
Further preferred technical solution is that the back side of the arc slope face inconsistent with the blind hole periphery is equipped with
Resilient cushion.The setting of resilient cushion, when reducing damping block along the sliding of blind hole length direction, between arc slope and step side
It hits, further improves the effect of damping noise reduction.
Advantages and beneficial effects of the utility model lie in that damping block is arranged in the access panel, make air filter housing
Between access panel have certain buffering, it is simple and reasonable, have good damping noise reduction effect.Access panel step
Bottom surface is equipped with rubber seal, further reduces noise and the damage of cover board and shell collision generation, while also having sealing
Effect avoids the dust outside filtering element for air filter by filtering isolation from escaping.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model access panel；
In figure: 1, blind hole；2, damping block；3, arc slope；4, spring；5, resilient cushion.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
As shown in Figure 1, a kind of filter cylinder access panel for deduster, the inspection cooperated including manhole and the manhole
Plate is built, the access panel is equipped with the step that sealing is matched with manhole, and the side of the step is circumferentially uniformly arranged
The bottom edge of several blind holes 1, the blind hole 1 is flushed with the bottom surface of the step, is embedded in the blind hole along blind hole length direction
The damping block 2 of sliding, the end that the damping block 2 stretches out blind hole are equipped with arc slope 3, and the central angle of the arc slope 3 is
60 ° -90 °, the end of the damping block insertion blind hole is equipped with the spring 4 along blind hole length direction.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
