And the right side lock box (not shown) being fixed in right case (not shown), the pin (figure being fixed on the lock box of right side
Not shown in), it is articulated with one in described left side lock box 40 for locking the hook 41 of pin, described handle is provided with to wear is connected on
Locking bar 22 within the lock box 40 of left side, described hook 41 is connected on this locking bar 22, and described positioner includes being movably arranged on
Alignment pin in left box body 80, the gear 60 being connected on locking bar 22, the bottom side of described alignment pin is formed with several and gear
The teeth groove (not shown) that the gear teeth 61 on 60 are meshed, described teeth groove is along the axial direction arrangement of alignment pin, the described right side
The location hole (not shown) interted for alignment pin is formed with casing.
The present embodiment, under the turning effort of handle, can drive the rotary work of hook 41, simultaneously also with moving gear 60
Rotary work, and then alignment pin is moved towards right case direction, it is finally inserted in the location hole being provided with to right case, make
41 must be linked up with pin lock regularly, is preventing left box body 80 right case relatively from moving up such that it is able to preferably avoid two casees
The phenomenon of relative displacement in body when assembled, can effectively mitigate the labour intensity of operating personnel, significantly improves casing assembly
Efficiency.
When needing to dismantle left and right two tanks, invert handle, hook 41 departs from from pin, the rotary work of gear 60 will
Drive the reset work of alignment pin, thus completing the dismounting of two tanks.
Preferably, the described gear teeth 61 are evenly distributed on the partial circle side face of gear 60, i.e. remaining periphery of gear 60
For smooth arc surface, spring 90 is installed between described alignment pin and left box body 80.During initial position, the gear teeth 61 with corresponding
Teeth groove be meshed, spring 90 is in the state compressed, when two gear teeth 61 are all departed from teeth groove, alignment pin no longer towards
During the bin movement on right side, the bounce of spring 90 will make alignment pin be securely seated between in location hole, avoid two further
The phenomenon of relative displacement in casing when assembled.
Preferably, the quantity of the described gear teeth 61 and teeth groove is 2.The quantity of the gear teeth 61 of the present invention and teeth groove can be passed through
Actual conditions are configured or 3 or 4.
Preferably, described left box body 80 includes being fixedly installed on lock box 40 back side of left side and for accommodating positioner
Backing plate 50, described backing plate 50 is formed with the through hole 51 for locking bar 22 insertion, this backing plate 50 can effective protection positioner.
Preferably, described alignment pin is included for inserting the first locator pin 70 and the first locator pin in location hole
70 the second locator pin 71 being fixedly connected, described teeth groove is formed at the bottom side of the second locator pin 71；The one of described spring 90
End is connected on the side wall of backing plate 50, and the other end of described spring 90 is connected on the second locator pin 71.In teeth groove and the gear teeth
Under 61 cooperation, the first locator pin 70 can be driven to be inserted in location hole.
Preferably, the diameter of described first locator pin 70 is less than the diameter of the second locator pin 71, and first can be facilitated to determine
Position pin portion 70 is inserted in location hole.
Preferably, it is installed with cover plate 30 before described left side lock box 40, described locking bar 22 is rotatably arranged on
On cover plate 30.In the presence of cover plate 30, the steadiness between handle and left side lock box 40 can be strengthened.
Preferably, described cover plate 30 is fixing by bolt 31 with left side lock box 40.It is ensured that covering in the presence of bolt 31
Fastness between plate 30 and left side lock box 40.
Preferably, the section of described locking bar 22 is regular hexagon, and described locking bar 22 sequentially passes through and is formed on hook 41
First inner hexagonal hole, the second inner hexagonal hole being formed on gear 60.
Preferably, the grip part 20 that the sleeve 21 that described handle includes being sleeved on locking bar 22 is fixedly connected with sleeve 21.
The rotary work to locking bar 22 for the setting person of being convenient to operation of grip part 20, can be arranged similar to people's hand-type on grip part 20
Groove, operator puts his hand in groove, can further facilitate the rotary work to locking bar 22 for the operator.
The locking bar 22 of the present invention sequentially passes through the first inner hexagonal hole, through hole 51 and the second inner hexagonal hole, drives hook 41
Rotation, meanwhile, with the rotation of moving gear 60, thus drive the second locator pin 71 and the first locator pin 70 towards right case
Move in direction.During beginning, the gear teeth 61 are meshed with corresponding teeth groove, and spring 90 is in the state compressed, then locking bar 22
Start to rotate, drive the synchronous rotary of locking bar 22 and gear 60, in the presence of the gear teeth 61 on gear 60 and teeth groove, alignment pin
Towards the motion of location hole direction.When locking bar 22 continues rotary motion, two gear teeth 61 are all departed from teeth groove, alignment pin no longer court
When right case motion, the bounce of spring 90 will make alignment pin be securely seated between in location hole, and link up with 41 and will continue
Rotate, be finally locked on pin.
When needing to dismantle left and right two tanks, invert handle, hook 41 departs from from pin, and the gear teeth 61 of gear 60 rotate
To when engaging with teeth groove, the reset work of alignment pin will be driven, and spring 90 will continue to be compressed, thus completing tearing open of two tanks
Unload.
Specifically, the sealed process of the present invention is as follows:
(a) as shown in figure 4, now spring 90 be in the state compressed, the gear teeth 61 are meshed with teeth groove；
B (), then as shown in figure 5, locking bar 22 starts to rotate, hook 41 and gear 60 also begin to synchronous rotation, promote the
One locator pin 70 and the second locator pin 71 move towards location hole direction；
C () is then as shown in fig. 6, locking bar 22 continues rotation, hook 41 and gear 60 also synchronous continuation rotation, the first positioning
Pin portion 70 and the second locator pin 71 continue to move towards location hole direction, and one of gear teeth 61 and teeth groove start to depart from；
D () is then as shown in fig. 7, locking bar 22 continues rotation, hook 41 and gear 60 also synchronous continuation rotation, the first positioning
Pin portion 70 and the second locator pin 71 continue to move towards location hole direction, and the another one gear teeth 61 and teeth groove also begin to depart from.
E () is last as shown in figure 8, locking bar 22 continues rotation, and also synchronization continues rotation for hook 41 and gear 60, but due to
The all of gear teeth 61 and teeth groove have been detached from, so the no longer direction towards location hole is moved by alignment pin, and in spring 90
In the presence of bounce, the first locator pin 70 is fixedly secured in location hole so that right case can not occur relatively
Mobile, hook 41 is final and pin locks.As two casings dismantled, only locking bar 22 need to be inverted and just may be used.
Moreover, it is noted that the spring 90 of the present invention has been not the effect resetting, and it is made by the bounce-back of spring 90
First locator pin 70 is firmly inserted in positioning in the hole by power, and the alignment pin of the present invention is the gear teeth 61 and the tooth by gear 60
Engaging each other of groove is resetted, it is to avoid two Box body dislocation and block alignment pin so that alignment pin showing of being not easy to return
As.
For a person skilled in the art, can technical scheme as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the protection model that all should belong to the claims in the present invention
Within enclosing.
