Abstract
The utility model discloses a liquid crystal protector in an engineering machinery instrument. The liquid crystal protector in the engineering machinery instrument comprises a liquid crystal, a circuit board, a fixing board and a shell body. The liquid crystal is fixedly arranged on the shell body through the fixing board. The circuit board is placed above the fixing board. Protective casings are installed all round the liquid crystal and on the upper rim and the lower rim of the liquid crystal. The adopted installation way of the liquid crystal is flexible connection. In a compact-structure type instrument, due to the material character of silica gel, requirements for precision of silica gel protective casing parts are low, and simultaneously, in the work of engineering machinery, the silica gel protective casing parts can play a role of cushioning, thereby enabling the liquid crystal to bear less force and to be difficult to damage.
Description
Technical field
The utility model belongs to the engineering mechanical instruments technical field, relates to a kind of liquid crystal protection structure, relates in particular to liquid crystal fender guard in a kind of engineering mechanical instruments.
Background technology
Construction machinery and equipment refers to the mechanical equipment for constructions such as building, road, bridge, tunnel, water conservancy, railways.Along with the development of economic construction, the output of construction machinery and equipment also is on the increase, and the instrument supporting as construction machinery and equipment also increases thereupon.Because the work under bad environment of construction machinery and equipment; alternation and impact load are large; therefore the structure design for engineering mechanical instruments just is even more important; particularly even more important to the protection structure design of liquid crystal in the engineering mechanical instruments; at present; the liquid crystal mounting means is illustrated in fig. 1 shown below in the engineering mechanical instruments, and liquid crystal 1 is fixed on the wiring board 4 by erection column 3 and screw 2, and this mode is hard the connection.In the instrument of compact conformation type, higher to the accuracy requirement of erection column 3.In the work of construction machinery and equipment, the suffered force rate of liquid crystal 1 is larger, easily damages.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides liquid crystal fender guard in a kind of engineering mechanical instruments.
The utility model is achieved by following technical solution.
Liquid crystal fender guard in a kind of engineering mechanical instruments comprises liquid crystal, wiring board, adapter plate and housing, and described liquid crystal is fixedly mounted on the housing by adapter plate, and wiring board places the adapter plate top, and lower edge is provided with protecting sleeve around liquid crystal and on the liquid crystal.
Above-mentioned protecting sleeve adopts elastomeric material to make.
Adopt the technical program, be because this mode for being flexible coupling, in the instrument of compact conformation type, because the material behavior of silica gel is lower to the accuracy requirement of Silicone Case, the while, Silicone Case played the effect of buffering in the work of construction machinery and equipment.
The beneficial effects of the utility model are:
Compared with prior art, the utility model reduces the suffered power of liquid crystal owing to increasing the effect that the protecting sleeve part of a silica gel plays buffering in the liquid crystal outside, is not easy to damage.
Description of drawings
Fig. 1 is traditional liquid crystal mounting structure schematic diagram;
Fig. 2 is the utility model liquid crystal mounting structure schematic diagram.
Among the figure: 1-liquid crystal, 2-erection column, 3-screw, 4-wiring board, 5-adapter plate, 6-protecting sleeve, 7-housing.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
Liquid crystal fender guard in a kind of engineering mechanical instruments; comprise liquid crystal 1, wiring board 4, adapter plate 5 and housing 7; described liquid crystal 1 is fixedly mounted on the housing 7 by adapter plate 5, and wiring board 4 places adapter plate 5 tops, and lower edge is provided with protecting sleeve 6 around liquid crystal 1 and on the liquid crystal 1.
Above-mentioned protecting sleeve 6 adopts elastomeric material to make.
