Description
Technical Field
The utility model relates to the technical field of sealing structures, in particular to an instrument shell with a double-sealing structure.
Background
The waterproof grade GB/T6968-2019 national standard requirement of the existing film type gas meter shell is above IP54, and in consideration of cost and installation environment requirements, gas meter manufacturers generally design two shells, wherein one shell is IP54 (no sealing gasket is arranged between an upper cover and a bottom shell), and the installation environment is suitable for being installed indoors; the other shell is IP65 (sealing gasket is arranged between the upper cover and the bottom shell) and can be installed outdoors. Two sets of dies are required to be opened, so that the cost is high, and time and labor are wasted.
Two sets of dies are required to be opened for producing the two shells, so that the cost is high, and time and labor are wasted.
Disclosure of utility model
According to the instrument shell with the double-sealing structure, the spigot is arranged between the upper cover and the bottom shell to serve as a heavy sealing structure, the sealing gasket is further arranged on the basis of the spigot structure to serve as a double sealing structure, and sealing performances of different grades can be achieved only by one set of die, so that die opening cost is reduced, and time and labor are saved.
To achieve the above object, the present utility model provides a meter case having a double seal structure, comprising: an upper cover, a bottom case and a sealing gasket;
the joint of the upper cover and the bottom shell is provided with an adaptive spigot, and the spigot adopts a Chinese character 'ji' -shaped structure;
The shape and the size of the sealing gasket are matched with those of the spigot, and the sealing gasket is arranged at the spigot and is clamped by the upper cover and the bottom shell to realize sealing.
In the above technical solution, preferably, only the sealing level of the spigot between the upper cover and the bottom case reaches IP54.
In the above technical solution, preferably, a sealing grade of the double sealing structure in which the spigot and the gasket are disposed between the upper cover and the bottom case reaches IP65.
In the above technical solution, preferably, the sealing gasket is disposed at a junction between the boss and the groove of the spigot.
In the above technical solution, preferably, the sealing gasket is attached to and covers the whole butt joint of the spigot.
Compared with the prior art, the utility model has the beneficial effects that: the spigot is arranged between the upper cover and the bottom shell to serve as a heavy sealing structure, and the sealing gasket is further arranged on the basis of the spigot structure to serve as a double sealing structure, so that sealing performances of different grades can be realized only by one set of die, the die opening cost is reduced, and time and labor are saved.

fig. 2 is a schematic structural view of a meter housing with a double seal structure according to another embodiment of the present utility model.
In the figure, the correspondence between each component and the reference numeral is:
1. the sealing device comprises an upper cover, a bottom shell, a sealing gasket and a spigot.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model is described in further detail below with reference to the attached drawing figures:
As shown in fig. 1 and 2, a meter case having a double seal structure according to the present utility model includes: an upper cover 1, a bottom shell 2 and a sealing gasket 3;
the joint of the upper cover 1 and the bottom shell 2 is provided with a spigot 4 which is matched with each other, and the spigot 4 adopts a Chinese character 'ji' -shaped structure;
The shape and the size of the sealing gasket 3 are matched with those of the spigot 4, and the sealing gasket 3 is arranged at the spigot 4 and clamped by the upper cover 1 and the bottom shell 2 to realize sealing.
In this embodiment, through setting up tang 4 as a heavy seal structure between upper cover 1 and the drain pan 2, still set up sealed pad 3 as dual seal structure on tang structure's basis, only need one set of mould can realize the sealing performance of different grades, reduced the die sinking cost, labour saving and time saving.
Specifically, the seam allowance 4 of the structure of the Chinese character 'ji' shape can form a certain degree of sealing effect, and the sealing gasket 3 is overlapped on the seam allowance 4, so that the sealing effect can be further enhanced. Thus, the same mold opening can be adopted for the instrument housings with two sealing grades, so that the mold opening cost can be reduced.
In the above embodiment, it is preferable that only the sealing level of the spigot 4 is provided between the upper cover 1 and the bottom case 2 to reach the IP54, so that the IP54 sealing level can be achieved only by the spigot 4 without the gasket 3.
In the above embodiment, it is preferable that the seal level of the double seal structure in which the spigot 4 and the gasket 3 are provided between the upper cover 1 and the bottom case 2 is IP65, and the gasket 3 is provided on the spigot 4, so that the seal level of IP65 can be achieved.
In the above embodiment, it is preferable that the laying position of the gasket 3 includes two setting modes, specifically including:
(1) The sealing gasket 3 is arranged at the joint of the boss of the spigot 4 and the groove;
(2) The whole butt joint department of sealed pad 3 laminating cladding tang structure fills up and establishes complete sealed pad 3 in whole junction between upper cover 1 and drain pan 2, improves sealed sealing stability and sealed effect.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
