The technical problems to be solved in the utility model is for drawbacks described above, a kind of electromotor CH spraying system control unit damping heat ray filter, this electromotor CH spraying system control unit damping heat ray filter simple in construction, good damping result, the heat that can effectively completely cut off on body to be damped are provided.
In order to solve above-mentioned technical problem, this utility model includes the supporting plate for installing CH spraying system control unit, supporting plate is bolted on body to be damped, it is structurally characterized in that: be set with cushion blocking on the bolt between described body to be damped and supporting plate, bolt between described supporting plate and nut is also set with cushion blocking, between described two cushion blockings, is provided with certain distance.
Described cushion blocking includes cylindrical body, and the middle part of described cylindrical body is provided with the through hole being available for bolt traverse, is provided with rubber damping pad between described cylindrical body and supporting plate.
Described cylindrical body includes land and overhanging section, and overhanging section is vertically arranged with land, and rubber damping pad is arranged between overhanging section of outer surface and land lower surface.
The lower loop of described rubber damping pad is provided with the card dress portion coordinated with supporting plate.
The spacing of described two cushion blockings is 1mm-3mm.
Distance between overhanging section of lower surface of described two cushion blockings is 1mm-3mm.
Described cylindrical body is made up of carbon steel sheet or corrosion resistant plate; Described rubber damping pad is made up of butyronitrile material.
Described two cushion blockings are as the criterion with supporting plate mid-depth line and are symmetrical arranged.
Advantageous effect after employing such scheme is: cushion blocking is sleeved on the bolt between body to be shaken and supporting plate, cushion blocking is installed between supporting plate and body to be damped, and the cushion blocking between body to be shaken and supporting plate can be decayed the vibration transmitted on body to be damped; Cushion blocking is sleeved on the bolt between supporting plate and nut, cushion blocking is installed between supporting plate and nut, owing to bolt is tightened on body to be damped, therefore also can some vibration be delivered on supporting plate by nut, the vibration that nut can be transmitted by this cushion blocking decays, and two-stage vibration damping can improve effectiveness in vibration suppression of the present utility model; Being provided with certain distance between two cushion blockings, ensure that time bolt is tightened that rubber damping pad will not be compressed, thus ensure that rubber damping pad has vibration-damping function always; Rubber damping pad is made up of butyronitrile material; butyronitrile material has relatively low heat conductivity and good heat-proof quality, it is possible to completely cut off the heat above body to be damped, so that the temperature of CH spraying system control unit is unlikely to too high; better protect electronic component, extend its service life.
In sum, this utility model simple in construction, good damping result, the heat that can effectively completely cut off on body to be damped.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the mounting structure figure of cushion blocking.
Detailed description of the invention
As Figure 1-Figure 2, this electromotor CH spraying system control unit damping heat ray filter includes the supporting plate 1 for installing CH spraying system control unit, supporting plate 1 is fixed on body to be damped by bolt 2, bolt 2 between body to be damped and supporting plate 1 is set with cushion blocking 3, the bolt 2 between supporting plate 1 and nut is also set with cushion blocking 3. Cushion blocking 3 includes cylindrical body 31, is provided with rubber damping pad 32 between cylindrical body 31 and supporting plate 1. In the present embodiment, cylindrical body 31 is common carbon steel plate or corrosion resistant plate; rubber damping pad 32 is nitrile rubber; butyronitrile material has relatively low heat conductivity and good heat-proof quality; the heat above body to be damped can be completely cut off; so that the temperature of CH spraying system control unit is unlikely to too high; better protect electronic component, extend its service life. Rubber damping pad 32 and cylindrical body 31 strong bond are integrated. Cylindrical body 31 includes land and overhanging section, and overhanging section is vertically arranged with land, overhanging section also is provided be available for the through hole of bolt 2 traverse, generally hollow T-shaped of cylindrical body 31. Rubber damping pad 32 is arranged between overhanging section of outer surface and land lower surface, and the lower loop of rubber damping pad 32 is provided with the card dress portion coordinated with supporting plate 1, so that cushion blocking 3 is installed between supporting plate 1 and body to be damped. In the present embodiment, rubber damping pad 32 is also the T-shaped of hollow, the bottom thus making rubber damping pad 32 also forms overhanging section, and overhanging section of rubber damping pad 32 and overhanging section of cylindrical body 31 bond together and be inserted simultaneously in the gap between supporting plate 1 and bolt 2.Cushion blocking 3 can be decayed the vibration transmitted on body to be damped. Another one cushion blocking 3 is installed between supporting plate 1 and nut, owing to bolt 2 is tightened on body to be damped, therefore also can some vibration be delivered on supporting plate 1 by nut, and the vibration that nut can be transmitted by cushion blocking 3 decays. In the present embodiment, two cushion blocking 3 structures are identical, and the two is as the criterion with supporting plate 1 mid-depth line and is symmetrical arranged, and namely overhanging section of two cushion blockings 3 is symmetrical arranged.
With reference to accompanying drawing 1 and accompanying drawing 2, between two cushion blockings 3, it is provided with certain distance. This distance is 1mm-3mm, and namely the distance between 3 overhanging sections of end faces of two cushion blockings is 1mm-3mm, and in the present embodiment, this distance elects 2mm as. The distance that bolt 2 does not tighten between front 3 overhanging sections of end faces of two cushion blockings is 2mm, bolt has the screw-down torque of a regulation, thickness by appropriate design vibration isolation rubber, when bolt 2 tightens, distance between two cushion blocking 3 overhanging sections end faces is reduced to 0mm by 2mm, this moment is just suitable screw-down torque, even if now continuing to bolt on 2, because the lower surface of two overhanging section of cushion blockings 3 can contact prop up, so the moment being applied on rubber damping pad 32 is without being further added by, this ensures that there the damping effect of two cushion blockings.
The present embodiment medium-height trestle plate 1 is fixed on body to be damped by four bolts 2, and each bolt 2 is all set with two cushion blockings 3, improves effectiveness in vibration suppression.
This utility model is not limited to above-mentioned detailed description of the invention, those skilled in the art, under the premise without departing from spirit and scope of the present utility model, can do some changes and modification. Protection domain of the present utility model should be as the criterion with claim of the present utility model.
