Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
Such as Fig. 1, the preferred embodiment of the safeguard structure of the of the present utility model a kind of lithium battery group shown in 2 and 3, including casing 3 and the case lid 1 mating setting with casing 3, casing 3 and case lid 1 all adopt waterproof material to make, its surface is all coated with high-abrasive material structure sheaf, high-abrasive material structure sheaf surface is also wrapped on antistatic film structure sheaf, antistatic film structure sheaf is detachably arranged on casing 3 and case lid 1 respectively, case lid 1 is detachably connected on casing 3, casing 3 side has groove 5, groove 5 notch correspondence case lid 1 is arranged, groove 5 is embedded in and is provided with adhesive tape 4, adhesive tape 4 adopts ethylene-propylene diene copolymer material to make, casing 3 is respectively equipped with electric components installing hole 2 and the detection hole 6 for airtight test, electric components installing hole 2 more than one.
It is provided with rubber sleeve in described electric components installing hole 2.The effect that buffer stop connects can be played.
Annular stricture of vagina it is provided with in described rubber sleeve.Convenient and mounting structure is connected.
Described adhesive tape 4 adopts that many thin tree laces are stranded to be formed.Pulling force is higher, is not easily broken.
The described built-in reinforcement of adhesive tape 4.Good reinforcement interconnection function can be played.
The safeguard structure size of a kind of lithium battery group of utility model of the present utility model is just pairing easily, and can be prevented effectively from produce elastic deformation, high temperature-proof, fire-retardant and insulation effect, effectively inside can be detected simultaneously, air-tightness is extremely strong, greatly strengthen overall sealing performance, self parts is completely embedded, and has good stationarity.Casing 3 and case lid 1 all adopt waterproof material to make, and substantially increase water resistance, it is to avoid current entrance affects internal component and normally uses；Its surface is all coated with high-abrasive material structure sheaf, and high-abrasive material structure sheaf surface is also wrapped on antistatic film structure sheaf, has wear-resisting and antistatic property concurrently, and result of use is better；Antistatic film structure sheaf is detachably arranged on casing 3 and case lid 1 respectively, and case lid 1 is detachably connected on casing 3, it is simple to carries out assembling and changes；Casing 3 side has groove 5, and groove 5 notch correspondence case lid 1 is arranged, and groove 5 is embedded in and is provided with adhesive tape 4, and adhesive tape 4 adopts ethylene-propylene diene copolymer material to make, and has good being tightly connected property.
Principle of work and power: when casing covers with case lid, it is designed in the groove 5 of Box Cover tape edge edge, one adhesive tape 4 of installation by adhering, owing to groove 5 is directed to adhesive tape 4, there is installation by adhering space, playing fixation, when casing 3 covers with case lid 1, adhesive tape 4 effect of being stressed is in stationary state, as elastic filler, sealing function can be effectively acted as again simultaneously.
Detection process: after the components and parts installing hole of casing 3 completes installation, then by casing 3 and case lid 1 installation.In casing 3, it is filled with 0.015Mpa air pressure finally by detection hole 6, then stops inflation and close detection hole 6.When this air pressure can be safeguarded 30 minutes and without decline, then it represents that this casing 3 is airtight qualified.If any decline, then utilize the places such as liquid edge lid seam, installing hole, the welding position that can produce foam, bubble to smear, produce then to show that there is gas leakage at this place if any bubble, then mend gas leakage point.Frontier inspection limit is repaiied in this approach, until it reaches the air pressure standard in the stipulated time, then with standard component, detection hole 6 is sealed.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine its technical scope according to right.
