Description
Technical field
The utility model relates to detector technical field, in particular to a kind of hand-held tester upper cover.
Background technique
For detecting ammonia, formaldehyde etc., hand-held tester is made of existing hand-held tester upper cover and pedestal, existing
Some upper covers and pedestal are screwed, and for existing upper cover due to the requirement of weight and material cost, what can be done is more and more thinner,
Upper cover surrounding is easy for stress Inward deflection or breakage occur in this way, thus will affect the use of hand-held tester.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of hand-held tester upper covers, solve upper cover and are easy to become
Shape or the problem of breakage.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of hand-held tester upper cover, including upper cover plate, the upper cover plate rear end is equipped with ring frame, on the upper cover plate
Equipped with display screen mounting hole and key hole, the upper cover plate rear end face is equipped with multiple screw connection columns, the ring frame inner wall
It is equipped with L-type groove with ring frame rear end face junction, the ring frame inner wall is equipped with a plurality of rib, the rib rear end face
In the same plane with the ring frame rear end face.
Further, the outer wall at left and right sides of the ring frame is designed with tread plate.
Further, four display screens are uniformly provided on the upper cover plate rear end face of the display screen mounting hole surrounding to connect
Connect column.
Further, the upper cover plate rear end face of the key hole surrounding is equipped with key limitting casing.
By adopting the above technical scheme, due to being equipped with a plurality of rib, rib rear end face and the ring frame in ring frame inner wall
In the same plane, such rib can both reinforce the intensity of ring frame to rear end face, by that can also pacify to hand-held pedestal
Convex block mounted in L-type groove is limited, and is prevented upper cover deformation or damaged, is improved the service performance of upper cover.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view one of hand-held tester upper cover one embodiment of the utility model；
Fig. 2 is a kind of schematic perspective view two of hand-held tester upper cover one embodiment of the utility model；
Fig. 3 is the A-A enlarged structure schematic diagram in Fig. 2.
Figure number and its explanation:
1, upper cover plate；2, key hole；3, ring frame；4, tread plate；5, display screen mounting hole；6, key limitting casing；7, it shows
Display screen connecting column；8, screw connection column；9, rib；10, L-type groove.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to figs. 1 to Fig. 3, a kind of hand-held tester upper cover provided by the utility model, including upper cover plate 1, it is described on
1 rear end of cover board is equipped with ring frame 3, and the upper cover plate 1 is equipped with display screen mounting hole 5 and key hole 2,1 rear end of upper cover plate
Face is equipped with multiple screw connection columns 8, and 3 inner wall of ring frame and the 3 rear end face junction of ring frame are equipped with L-type groove
10,3 inner wall of ring frame is equipped with a plurality of rib 9,9 rear end face of rib and 3 rear end face of ring frame same flat
On face.
The ring frame 3 of the technical program includes the left plate, upper plate, right panel and the lower plate that are sequentially connected end to end, left plate, upper plate,
Right panel and the inner wall of lower plate are designed with rib 9, and the rib 9 of the inner wall of upper plate and lower plate is all two, the inner wall of left plate and right panel
Rib 9 all be three, certainly, specifically can according to require increase or reduce.Left plate, upper plate, right panel and lower plate are designed with L
Type groove 10, four 10 groups of L-type grooves circlewise L-type groove so that it is convenient to be cooperatively connected with the cricoid convex block of pedestal.Pass through muscle
Item 9 can increase resistance to compression and the support strength of upper cover, and the convex block on the pedestal of hand-held tester and the cooperation of L-type groove 10 position
When, convex block can be limited by rib 9, prevent 3 stress of ring frame to be easy Inward deflection or damage, and after rib 9
In the same plane, 9 rear end face of rib can also be used as the face with base contacts for end face and 3 rear end face of ring frame, in increase
The contact area of lid and pedestal reduces the possibility of upper cover or base groove.Ring frame 3 can be done by rib 9 it is thinner,
Material can be saved, it is light-weight, it is at low cost, to improve the service performance of upper cover.
The outer wall of 3 left and right sides of ring frame is designed with tread plate 4.Hand is facilitated to hold hand-held tester in this way.
Four display screen connecting columns 7 are uniformly provided on 1 rear end face of the upper cover plate of 5 surrounding of display screen mounting hole.
It can of course be arranged to other quantity according to actual requirement.
1 rear end face of the upper cover plate of 2 surrounding of key hole is equipped with key limitting casing 6.Key can be prevented in this way
Sideslip.
In conclusion the utility model is by being equipped with a plurality of rib, rib rear end face and the annular in ring frame inner wall
In the same plane, such rib can both reinforce the intensity of ring frame in back end of frame face, by can also be to hand-held pedestal
The convex block for being mounted on L-type groove is limited, and is prevented upper cover deformation or damaged, is improved the service performance of upper cover.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
