Description
Technical Field
The utility model belongs to the technical field of parking management equipment, concretely relates to parking management equipment with airtight valve.
Background
Parking management equipment is applied to in the open parking area, because parking management equipment does not shelter from in the open parking area, leads to equipment to stand wind and blows the sun, and for waterproof, at parking management equipment during operation, take place temperature variation in the sealed cavity, the internal and external unbalance of atmospheric pressure, a large amount of cold gas and steam in cooling back, dust etc. can get into equipment, reduce the life of equipment and directly wet the damage even, seriously influence parking management equipment's use.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a parking management equipment with airtight valve, including drain pan 1, airtight valve of metal 2 and waterproof silica gel circle 3, set up an airtight valve round hole in the drain pan 1, be convenient for install airtight valve of metal, set up a recess on airtight valve opening for place waterproof silica gel circle 3, the degree of depth of recess is the same with 3 thickness of waterproof silica gel circle, and the recess is filled completely to waterproof silica gel circle 3, and the diameter of recess is less than the diameter of the cap of airtight valve of metal 2, is greater than the diameter of the thread circle of airtight valve of metal 2.
Preferably, the airtight valve circular hole is located in the available space in the bottom case 1 except for the battery cover.
Preferably, the material of the metal gastight valve is copper.
The utility model has the advantages that: by adopting the scheme, the air tightness of the equipment can be effectively protected by the equipment-mounted airtight valve, air water vapor and dust are filtered, air circulation is not influenced, and the internal and external pressure difference is stabilized, so that the equipment can withstand wind and sunshine.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1 is a side view of a parking management apparatus with an airtight valve according to embodiment 1 of the present invention.
Fig. 2 is a sectional view of a parking management apparatus with an airtight valve according to embodiment 1 of the present invention.
Wherein: 1 is a bottom shell, 2 is a metal airtight valve, and 3 is a waterproof silica gel ring.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1: referring to fig. 1 and 2, the parking management equipment with the airtight valve comprises a bottom shell 1, a metal airtight valve 2 and a waterproof silica gel ring 3, wherein an airtight valve round hole is formed in the bottom shell 1, the metal airtight valve is convenient to install, a groove is formed in an airtight valve hole and used for placing the waterproof silica gel ring 3, the depth of the groove is equal to the thickness of the waterproof silica gel ring 3, the groove is completely filled with the waterproof silica gel ring 3, and the diameter of the groove is smaller than that of a cap of the metal airtight valve 2 and larger than that of a threaded ring of the metal airtight valve 2. The airtight valve circular hole is located in the available space in the bottom case 1 except for the battery cover. Can effectively protect parking management equipment's gas tightness behind parking management equipment installation airtight valve, filtration air steam, debris such as dust do not influence the circulation of air moreover, stabilize inside and outside pressure differential to make parking management equipment stand up to wind and blow the sunshine.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
