Abstract
The utility model discloses a film viewer, the viewing window size of which can be adjusted. The film viewer comprises a shell top and a shell bottom, wherein, an upper sliding tray I is internally arranged on the left side of the shell top, a lower sliding tray I is internally arranged on the left side of the shell bottom, and a left occluder is arranged between the upper sliding tray I and the lower sliding tray I; and an upper sliding tray II is internally arranged on the right side of the shell top, a lower sliding tray II is internally arranged on the right side of the shell bottom, and a right occluder is arranged between the upper sliding tray II and the lower sliding tray II. As for the film viewer, the occluders are arranged inside the film viewer; the size of the viewing window can be adjusted randomly and horizontally; steel balls are arranged between the film viewer shell and the occluders for matching, which reduces not only the sliding resistance but also the sliding noise; and the use is convenient on the base of not affecting the whole beauty of the film viewer.
Description
Technical field
The utility model relates to a kind of viewbox, specifically relates to the viewbox that a kind of size of view window can be regulated.
Background technology
Industrial x-ray egative film viewbox is that industrial x-ray detects the visual plant that carries out radiographic film observation and evaluation.Be characterized in the brightness height, reach as high as 10
5Cd/m
2More than, the view window size is generally about 200 * 60mm, when observing little egative film or carrying out the zonule evaluation, egative film can not cover whole form, effectively do not block if do not take, high-intensity light causes damage to commenting the sheet personnel, so JB/7902-1999 " industrial radiography egative film viewbox " standard-required must be equipped with shadow shield.
At present, all viewboxs all are equipped with a cover shadow shield, as shown in Figure 1.Shortcoming is: 1, lose easily; 2, need constantly to change shadow shield, inconvenience in the use; 3, bending distortion easily, influence is used; 4, manufacturing cost increases, waste material.
Summary of the invention
The purpose of this utility model provides a kind ofly can regulate the viewbox of view window size arbitrarily.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises that the inside, left side of pushing up at shell is provided with sliding tray I at the bottom of shell top and the shell, and the inside, left side at the bottom of the shell is provided with lower slider groove I, between last sliding tray I and the lower slider groove I left shadow shield is set; Inside, right side on the shell top is provided with sliding tray II, and the inside, right side at the bottom of the shell is provided with lower slider groove II, between last sliding tray II and the lower slider groove II right shadow shield is set.
Be equipped with the ball that matches with last sliding tray I and lower slider groove I in the upper and lower of left shadow shield.
Be equipped with the ball that matches with last sliding tray II and lower slider groove II in the upper and lower of right shadow shield.
Above-mentioned ball is a steel ball.
Adopt the utility model of technique scheme, shadow shield is set to the inside of viewbox; Can regulate the size of view window in the horizontal direction arbitrarily; Between viewbox shell and the shadow shield steel ball is set and cooperates, both reduced sliding resistance, lowered slip noise again; Easy to use, do not influence the overall appearance of viewbox again.

Fig. 3 is the arrangenent diagram of two shadow shields and viewbox body in the utility model;
Fig. 4 is the structural representation of shadow shield in the utility model.
Embodiment
As shown in Figure 1, the utility model comprises at the bottom of shell top 1 and the shell 2, in the inside, left side on shell top 1 sliding tray I3 is set, and 2 inside, left side is provided with lower slider groove I5 at the bottom of the shell, between last sliding tray I3 and the lower slider groove I5 left shadow shield 7 is set.Like this, left shadow shield 7 can horizontally slip in last sliding tray I3 and lower slider groove I5 back and forth.For the resistance that reduces to slide, lower slip noise simultaneously, be equipped with the ball 9 that matches with last sliding tray I3 and lower slider groove I5 in the upper and lower of left shadow shield 7, as shown in Figure 4.
Based on same symmetrical structure, inside, right side on shell top 1 is provided with sliding tray II4,2 inside, right side is provided with lower slider groove II6 at the bottom of the shell, between last sliding tray II4 and the lower slider groove II6 right shadow shield 8 is set, and left shadow shield 7 and right shadow shield 8 are horizontally disposed with.In addition, be equipped with the ball 9 that matches with last sliding tray II4 and lower slider groove II6 in the upper and lower of right shadow shield 8, as Fig. 2, shown in Figure 4.Simultaneously, reduce to minimum for guaranteeing the resistance that slides, above-mentioned ball 9 all adopts steel ball.
Principle of work of the present utility model is: as shown in Figure 3, left shadow shield 7 and right shadow shield 8 all have been arranged on the inside of viewbox, and are positioned at the left and right sides of viewbox body.Usually when not using shadow shield, left shadow shield 7 and right shadow shield 8 are hidden in viewbox inside, do not influence the overall appearance of viewbox.When real work, level spurs left shadow shield 7 and right shadow shield 8 as required, because left shadow shield 7 and right shadow shield 8 be arranged on the same surface level, and in other words in same track, thus the size that can regulate view window arbitrarily.
