CN201435193Y - Digital display device - Google Patents

Abstract

The utility model discloses a digital display device comprising the following structure: a bracket is internally provided with a spring plate; a boss is arranged on the spring plate; corresponding circular grooves are arranged on the spring plate and the bracket; the two circular grooves are respectively connected with two short shafts on fields; clamping grooves which are clamped with clamping platforms on the spring plate are arranged at the same side of the two short shafts on the fields; the fields rotate to drive the clamping grooves to be clamped with or separated from the clamping platforms; and the fields are positioned in a same plane with the bracket when the clamping platforms are clamped with the clamping grooves. The bracket and the spring plate form an integrated or separatedstructure; and when forming the separated structure, the bracket and the spring plate are fixed with each other by using screws or fixedly connected each other by spot welding. In the digital displaydevice, the fields are rotatablely combined with the spring plate and the bracket, and clamped and connected with the spring plate, thus having the advantages of accurate positioning, no backplane structure, and small occupied space.

Description

Numeric display unit

Technical field

The utility model relates to character display device, particularly index word display device.

Background technology

Display device commonly used partly is made up of panel, upset field etc., and the field rotating shaft is fixed on the panel, by field is overturn around the shaft, and the demonstration of realization field or do not show.Prior art generally has two kinds of implementations, and a kind of is that a backboard was close in the back after field was overturn, and realizes the steady display of field; Another kind of mode is by the wringing fit between upset field and the rotating shaft, also can simply realize position stability after upset.

The major defect of first kind of implementation is to regulate inconvenience, field need be left backboard and could regulate afterwards, and, need the space bigger, under the condition of limited of space, implement the comparison difficulty; The major defect of the second way is that the location is unreliable, and, after upset a period of time, because the wearing and tearing of rotating shaft or field can be lost positioning function.

Said structure exists structure to take up room greatly, locate inaccurate problem.

The utility model content

In view of this, the utility model is to provide numeric display unit, takes up room greatly, locatees inaccurate problem to solve above-mentioned display device structure.

For addressing the above problem, the utility model provides numeric display unit, comprise: have shell fragment in the support, have boss on the shell fragment, on shell fragment and support, have corresponding arc groove, two arc grooves are connected with two minor axises on the field respectively, the homonymy of two minor axises on the field, have with shell fragment on the draw-in groove that holds mutually of Ka Tai, field is rotated and is driven draw-in groove and hold with the card decometer or throw off, after Ka Tai and draw-in groove held, field and support were in same plane.

So two arc grooves respectively with field on two minor axises be connected to hold and fixedly connected or be rotationally connected;

Be rotationally connected for: described field and two minor axises are structure as a whole, and described minor axis and arc groove are rotationally connected;

Hold and be fixedly connected as: described two minor axises and described font are rotationally connected, and described minor axis and arc groove hold and be fixed together.

Described support and shell fragment are disjunctor or divide body structure; When dividing body structure, the employing screw fixes or spot welding is fixed together.

Device of the present utility model combines with shell fragment, support field is rotatable, and field holds connection mutually with shell fragment, accurate positioning, and do not have back board structure, have the little advantage that takes up space.

Embodiment

For clearly demonstrating the technical scheme in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.

Referring to Fig. 1, the device among the embodiment comprises support 1, has the shell fragment 2 of disjunctor or split in the support, has boss 21 on the shell fragment 2.When support 1 and shell fragment 2 are made the branch body structure, adopt screw to fix or spot welding is fixed together.Has corresponding arc groove at shell fragment 2 and support 1, two arc grooves respectively with field shown in Figure 2 on two minor axises 31 hold, Fig. 2, Fig. 3, field shown in Figure 4, the homonymy of two minor axises 31 on the field, have with shell fragment 2 on the draw-in groove 32 that holds mutually of card platform 21.

Field is installed to synoptic diagram such as the Fig. 5, shown in Figure 6 on support 1 and the shell fragment 2, rotate by control minor axis 31, field is rotated along arc groove, has different colors on two opposite faces of field, after the field rotation, card platform 21 is thrown off with draw-in groove 32, when field Rotate 180 degree, after being turn-over, card platform 21 holds again once again with draw-in groove 32.

Above-mentioned field and two minor axises 31 are integrative-structures, also two minor axises 31 and described font can be rotatably connected, minor axis and arc groove held be fixed together, when rotating field, minor axis 31 does not rotate, after can the realize field rotation, card platform 21 is thrown off with draw-in groove 32, when field Rotate 180 degree, promptly behind the turn-over, card platform 21 holds again once again with draw-in groove 32.

Field shows different colors by rotation, can form different numerals, numeral 2 as shown in Figure 8, device of the present utility model combines with shell fragment, support field is rotatable, and field holds connection mutually with shell fragment, accurate positioning, and do not have back board structure, have the little advantage that takes up space.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims (3)

1, numeric display unit, it is characterized in that, comprise: have shell fragment in the support, have boss on the shell fragment, on shell fragment and support, have corresponding arc groove, two arc grooves are connected with two minor axises on the field respectively, the homonymy of two minor axises on the field, have with shell fragment on the draw-in groove that holds mutually of Ka Tai, field is rotated and is driven draw-in groove and hold with the card decometer or throw off, after Ka Tai and draw-in groove held, field and support were in same plane.
