Optimize above-mentioned rack, the rack is a kind of sliceable and dismountable rack, is formed by multiple frame bodies 30.It should
Rack includes that horizontal splicing construction and vertical splicing construction can also erect so that two adjacent frame bodies 30 horizontal can splice
Straight splicing.In the present embodiment, user can select according to the quantity of the number of units of this test box 31 and the difference of test environment
Horizontal splicing or vertical splicing are selected, can be fixed and the bring wasting of resources to avoid frame dimensions in the prior art.For example,
There are five test boxs 31, when the height of test site is large enough to hold five test boxs 31, and user can also get at the top
Cabinet when, then vertical splicing can be used, splice five frame bodies 30, five cabinets are then mounted on corresponding and frame body 30
It is upper, for another example, there are ten test boxs 31, all vertical splicing is unrealistic at this time, even if place height can accommodate
Put ten cabinets on vertical direction, several cabinet users of the top do not allow easy to operate yet, and horizontal splicing can be used at this time
Mode, or it is five one group that ten frame bodies 30, which are divided, is then again mounted on ten cabinets on corresponding frame body 30 i.e.
It can.
Optimize above-mentioned horizontal splicing construction, the horizontal splicing construction includes the opposite sides the set on each frame body
Three connectors and the 4th connector, two adjacent frame bodies are spelled by the third connector and the 4th connector
It connects, can work in coordination between them, i.e., this rack and another rack cooperate.Wherein third connector be two card slots, the 4th
Connector is the fixture block that can correspond to two card slots of insertion, i.e., is connected two adjacent frame bodies 30 by the way of clamping
Come.Certainly, in addition to this, can also be connected by the way of screws bolts.This is all dismountable connection type.
Optimize above-mentioned vertical splicing construction, the vertical splicing construction includes being located at the first of 30 top and bottom of frame body to connect
The quantity of fitting and the second connector, the first connector and the second connector can have multiple, be allowed to more firm connection.Such as
There are four their quantity, these connectors are mounted on four corners of rack, in such a way that clamping is either threadedly coupled
It is attached.Equally they are also all dismountable connection types.
Continuing to optimize above-mentioned rack, the rack further includes the computer bracket for installing computer, and the two of the frame body 30
Side is equipped with several second installation positions 33 detachably installed for the computer bracket.It is designed in this way, it can be directly by all-in-one machine
It is mounted on computer bracket, is convenient for real-time operation.As a preferred scheme of the present embodiment, when there is multiple frame bodies 30,
In the same side of frame body 30, each second installation position 33 is respectively positioned between first installation position 32 of adjacent two, such as
After this installs computer, computer is not far from test box 31, operates this test box 31 on one side convenient for user, operates computer on one side.
Above scheme is advanced optimized, being detachably connected between computer bracket and frame body 30, which can use, to be threadedly coupled,
It can also be using clamping.
Continue to optimize above-mentioned frame body 30, if the top of the frame body 30 also is provided with detachably installing for the computer bracket
Dry third installation position 34.User can according to need the installation of selection computer bracket.
Continue to optimize above-mentioned rack, the rack further includes several battery trays for shelving battery, each battery tray
It corresponds with each frame body 30, is detachably connected between the corresponding frame body 30 of each battery tray.
Continue to optimize above-mentioned rack, 30 bottom of frame body is equipped with several universal wheels 35.It can be in order to machine frame movement to finger
Fixed position.As a preferred scheme of the present embodiment, it is mounted on lock piece 36 on each universal wheel 35, it can be with
Avoid its free to slide its locking by the lock piece 36 after being moved to specified position.
Embodiment seven:
The utility model embodiment also provides a kind of battery tester, including the battery testing for testing battery performance
Case and a kind of above-mentioned rack, the opposite sides of the battery testing case are equipped with side hanging part, and first installation position has two
A, two side hanging parts are removably mounted on respectively on two first installation positions.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
