Embodiment
As depicted in figs. 1 and 2, a kind of lithium battery pressure-bearing test gas explosion frock, including base, base cover and side seals Block;The base 1 is in rectangular-shape, and 1 upper surface of base is connected by location hole 1-2 and the locking of base cover 3, the base The experiment opening that bearing groove 1-1, the bearing groove 1-1 have been drawn in 1 upper surface is unfolded towards right flank, paving inside the bearing groove 1-1 Discharge pond 2, injecting hole cushion rubber 2-1 be filled between the compressed air injecting hole 5-3 of the inner side of the battery 2 and side seals block 5, The side seals block 5 is tightly connected by rubber pad 5-1 and battery safety valve 2-2, the side seals block 5 by screw with Base 1 is tightly connected.Wherein, tool assembly is produced for convenience, and frock shape of the invention is in rectangular-shape.Pass through cuboid The structure of shape fast and effectively can be modeled and put into production, and substantially increase production efficiency.In order to will effectively prepare in advance Good battery 2 is put into frock, and bearing groove 1-1 has been drawn in 1 upper surface of base.The experiment opening court of the bearing groove 1-1 Right flank is unfolded, and quickly can so be laterally inserted into battery 2, time saving and energy saving.In order to which battery 2 is sealed, holding Carry and be mounted with side seals block 5 and base cover 3 at the exposure of groove 1-1.Having been opened up at the same time on side seals block 5 conveniently to note Enter the injecting hole 5-3 of compressed air.Finally in order to ensure that compressed air is not revealed, in the compressed air injecting hole 5-3 It is corresponding with the injecting hole cushion rubber 2-1 in the outside of battery 2.In order to strengthen ductility of the battery safety valve 2-3 in frock, described Battery safety valve 2-3 and rubber pad 5-1 carries out sealing filling.Since the battery safety valve 2-3 wind pressure born is about 3Mpa, but The gas injection pressure for being detection is about 6Mp.So battery safety valve 2-3 is easy to air leakage phenomena occur.So in order to prevent this The generation of phenomenon, soft contact is done by rubber pad 5-1 with battery safety valve 2-3.Anti- battery safety valve 2-3 receive gas injection pressure to During external deformation, deformation complementation can be done by rubber pad 5-1.So it can prevent battery safety valve 2-3 from air leakage phenomena occur.
As depicted in figs. 1 and 2, the base 1 each has longitudinal screw hole 6-1 and horizontal screw hole at top and left part Be mounted with screw rod 8 in 7-1, the longitudinal direction screw hole 6-1 and horizontal screw hole 7-1 respectively, two screw rods 8 through longitudinal direction screw hole 6-1 with Horizontal screw hole 7-1 is fitting to connection with longitudinal pushing block 8 and horizontal pushing block 7 respectively, and 8 end of screw rod is equipped with butterfly bolt 9.Wherein, In order to allow the frock to can adapt to the battery 2 to be detected of different sizes, at the top of the base 1 and left part equipped with vertical To pushing block 8 and horizontal pushing block 7.Staff hole is by screw rod 8 through longitudinal direction screw hole 6-1 and transverse direction screw hole 7-1 respectively to longitudinal direction Pushing block 8 and horizontal pushing block 7 carry out the adjusting of size.Most at last mesuring battary 2 carry out effectively it is spacing, oozed in order to avoid there is compressed air Leakage.
As shown in Figure 1, the side horizontal of the longitudinal direction pushing block 8 and horizontal 7 ejection face of pushing block respectively with battery 2 contacts.Its In, due to longitudinal pushing block 8 and horizontal pushing block 7 be battery 2 squeeze by horizontal plane push away it is spacing.Become from usual electrical contact Be changed to face contact, spacing efficiency can be greatly improved, prevent squeeze push away it is spacing during there is battery run-off the straight so that nothing The situation of method face compressed air mouth occurs.
As shown in Figure 1,5 medial surface of side seals block has drawn two limiting slots 5-2, the limiting slot 5-2 and electricity Pond 2 it is raised corresponding, the limiting slot 5-2 is filled with rubber pad 5-1.Wherein, for the lug boss of 2 output terminal of match battery Point, draw two limiting slot 5-2 in 5 medial surface of side seals block.Also completed at the same time by the way of filled rubber pads 5-1 Processing in sealing contact.It so can effectively prevent and occur leaking out in seal process and jitter phenomenon.
As shown in Figure 3 and Figure 4, the top of base cover 3 is fixedly connected with handle 4, and 3 bottom of base cover is fixedly connected There are two boss 3-1, the through hole of the boss 3-1 transverse directions is corresponding with the through hole at 1 bottom chimb of base, the boss 3-1 Connected by screw and the locking of 3 bottom flange of base cover.Wherein, base cover 3 is opened in order to facilitate technical staff.In the base The top of lid 3 is fixedly connected with handle 4.And two boss 3-1 are fixedly connected with 3 bottom of base cover, recycle boss 3-1 is connected by screw and the locking of base cover 3.The stability that base cover 3 is connected with frock can so be strengthened.
To sum up, the present invention substantially increases the sealing performance of frock by the way of elastic extruding type sealing.It is original to squeeze Pressure mode is point contact, and the mode present invention employs face contact substantially increases tight type of the battery inside frock, into And avoid and the gas leak phenomenon that injecting hole off normal is brought is compressed when battery does pressure-bearing test.The filling of rubber pad is significantly more efficient to be carried The high matching degree of battery and frock.
Although the foregoing describing the embodiment of the present invention, those skilled in the art should be appreciated that this It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the principle of the present invention and essence, Protection scope of the present invention is only limited by the claims that follow.
