Battery pack；Inner casing includes the first end wall for being respectively arranged at the first open end of shell and the second open end for being set to shell
Second end wall, the first open end cap are equipped with end cap, are provided with first seal between end cap and the first end wall, the second end wall it is outer
Abutting between peripheral wall and the inner wall of the second open end has second seal；The first seal and the second seal are used for
The shell, inner casing and the end cap is set to connect the battery case to form sealing.Locking clamping device tool provided by the invention
There is good waterproof performance, and easy to carry.
As shown in Figure 1, the present invention provides a kind of locking clamping devices, comprising: collet 1, the collet 1 includes for pressing from both sides
Hold product clamping cylinder 11 and the fixed ring 12 being sheathed on outside the clamping cylinder 11, the clamping cylinder 11 by least three each other it
Between be provided with 111 circumferential direction of clamping piece in gap and be enclosed, and one end offers the holding holes 112 for product clamping, each
Clamping piece 111 is connect with 12 center of fixed ring by a connection piece 110, and the both ends of each clamping piece 111 can be with
Corresponding every a connection piece 110 is fulcrum relative rotation, to change the aperture of the holding holes 112 to lock product；Regulating part
2, it is set to the described one end of clamping cylinder 11 far from product clamping, for keeping each clamping piece 111 remote under used in the external force
It with the connector 110 is fulcrum rotation from one end of product clamping, to adjust the apertures of the holding holes 112 to lock production
Product.
In the present embodiment, there are six identical clamping pieces 111 for setting, when 111 quantity of clamping piece is very few, are easy to cause tune
The aperture for saving holding holes 112 is not accurate enough, and when clamping piece quantity is excessive, the dynamics of clamping is not big enough, and collet intensity is not high,
It is also inconvenient for processing.Each clamping piece 111 with each corresponding connector 110 and the one of the fixed ring 12 at
Type, it is each since each described one end of clamping piece 111 far from product clamping is fulcrum rotation with the connector 110
The clamping piece 111, each connector 110 and the fixed ring 12 are spring steel material production, connector 110
When thickness is too small, the intensity of connector 110 is inadequate, when clamping piece 111 being be easy to cause to rotate with connector 110 for fulcrum, clamping
The fracture of the junction of part 111 and connector 110, when thickness is excessive, when clamping piece 111 is difficult to rotate with connector 110 for fulcrum,
Therefore, in the present embodiment, each connector 110 with a thickness of 2-4mm.
Specifically, the clearance distance between every adjacent two clamping piece 111 is 1-2mm, and between every adjacent two connector 110
Clearance distance be also 1-2mm.When clearance distance is excessive, piece-holder dynamics is inadequate, when gap is too small, two adjacent clamping pieces
Frictional force can be generated between 111 and connector 110, so that the adjusting of holding holes 112 is difficult to realize.
In the present embodiment, the clamping cylinder 11 offers close to one end of the regulating part 2 and connects with the holding holes 112
Logical adjustment hole 113, the adjustment hole 113 abut with the regulating part 2 and form default tune with the axis of the clamping cylinder 11
Save angle, according to lever principle, preset adjust angle it is excessive when, the degree of regulation of holding holes 112 is not high enough, presets and adjusts angle
When too small, need the mobile enough distances of regulating part 2 that could effectively adjust holding holes 112, therefore in the present embodiment, preset and adjust
Angle is 45-75 °.
Specifically, the regulating part 2 includes the pressed end 21 that is slidably connected in the adjustment hole 113 and separate with institute
State the connecting pin 22 of 113 one end of adjustment hole, the axis of the pressed end 21 and the clamping cylinder 11 forms default the adjustings folder
Angle, the pressed end 21 are slided in the adjustment hole 113 to squeeze each clamping piece 111 and make it with the connector
110 apertures rotated for fulcrum to adjust the holding holes 112.
As described in Figure 1, the locking clamping device in the present embodiment further includes rear top pillar 3, the rear top pillar 3 and the connection
Side of the end 22 far from the pressed end 21 abuts, for mobile towards 22 direction of connecting pin under external force, so that
The pressed end 21 is slided in the adjustment hole 113 to adjust the aperture of the holding holes 112.
In order to adjust clamping piece 111 with connector 110 as the position of the fulcrum in fulcrum rotation process, adjustment clamping of being more convenient for
The outer wall section in hole 112, each clamping piece 111 is recessed to form groove 114, each connector 110 and corresponding folder
The junction of gripping member 111 is located on the concave surface of the groove 114.
Referring to figs. 1 and 2, at least two first fixation holes 121, the fixed board 4 are offered in fixed ring 12
Upper each first fixation hole 121 of correspondence offers the second fixation hole 41, and each fixation hole 121 and described second are consolidated
Hole 41 is determined for passing through fixing piece 123 so that the fixed ring 12 is fixedly connected on fixed board 4；In the present embodiment,
First fixation hole 121 and four the second fixation holes 41 there are four being respectively set；The fixed ring 12 is towards the fixed board 4
One side section convexes to form the first limited step 122, and the side of fixed board 4 towards the fixed ring 12 corresponds to described
One limited step 122 is formed with the second limited step 42, and first limited step 122 is connected to second limited step 42
It connects.
In conclusion application scheme at least has following advantageous effects compared with the existing technology:
1) clamping high reliablity and clamping precision height；
2) concentricity precision can be increased to 0.005mm by 0.02mm in the prior art.
Above disclosed is only a preferred embodiment of the present invention, cannot limit the power of the present invention with this certainly
Sharp range, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and weighs according to the present invention
Benefit requires made equivalent variations, still belongs to the scope covered by the invention.
