Preferably, the inner cavity of the mounting groove is equipped with gasket seal;
Preferably, the protective cover is clear glass protective cover;
Preferably, the damping shell is connected through a screw thread with annular mounting shell;
Preferably, the outer surface of the ring cover is equipped with foam-rubber cushion.
Advantageous effect:
The utility model makes pressure gauge when receiving external collision, subtracting inside damping shell by designing a kind of damping shell Shake spring can store the power being subject to, and play good cushioning effect, protect the safety of pressure gauge, keep it light It is fragile, solve the problems, such as that pressure gauge easily receives damage;When protective cover damages, without entire pressure gauge is needed to change, only Protective cover is needed to change, saves maintenance cost, and vacuum pump connection exhaust pipe can be used annular mounting shell and dial Space between protection panels is set as vacuum state, makes it have good leakproofness.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other drawings may also be obtained based on these drawings.
FIG. 1 is a schematic structural view of the utility model.
Reference numeral is as follows:1, pressure watch shell, 2, dial protection panels, 3, mounting hole, 4, annular mounting shell, 5, solid Determine bolt, 6, mounting groove, 7, protective cover, 8, exhaust pipe, 9, sealing cover, 10, damping shell, 11, groove, 12, damping spring, 13, Ring cover.
Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained without creative efforts belong to The range of the utility model protection.
It is realized at this in novel description, it should be noted that term "center", "lower", "left", "right", " is erected at "upper" Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only The utility model and simplifying describes for ease of description, do not indicate or imply the indicated device or element must have it is specific Orientation, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
Referring to Fig. 1:A kind of pressure gauge with protective device, including pressure watch shell 1, dial protection panels 2, mounting hole 3, annular mounting shell 4, fixing bolt 5, mounting groove 6, protective cover 7, exhaust pipe 8, sealing cover 9, damping shell 10, groove 11, damping The surface inserting of spring 12 and ring cover 13, the pressure watch shell 1 has dial protection panels 2, the dial protection face Four groups of mounting holes 3 are equidistantly equipped on 1 surface of pressure watch shell of the surrounding of plate 2, the annular mounting shell 4 passes through fixing bolt 5 It is fixedly connected with mounting hole 3, the inner wall of the mounting shell 4 is equipped with a circle mounting groove 6, and the inner cavity of the mounting groove 6 is equipped with sealing Gasket, the protective cover 7 are fastened on 6 inner wall of mounting groove, and the protective cover 7 is clear glass protective cover, the annular mounting shell 4 Surface be equipped with damping shell 10, the damping shell 10 4 is connected through a screw thread with annular mounting shell, and the surface of the damping shell 10 is set Fluted 11, the inner wall horizontal homogeneous of the groove 11 is equipped with multigroup damping spring 12, and the inner cavity of the groove 11 is equipped with annular The outer surface of lid 13, the ring cover 13 is equipped with foam-rubber cushion, and the ring cover 13 is solid by damping spring 12 with 11 inner wall of groove Fixed connection.
