Problems solved by technology

[0011] Furthermore, due to the undesired increase in the size of the cover body 2, as a result, dust tends to accumulate on the side surface portion 20b of the race portion 20 on the upper portion of the cover body 2.
In this way, for example, when working in a clean room, the accumulated dust is scattered on the product, which has a bad influence on the product
[0012] In addition, as mentioned above, the elastic piece 5 has a large amount of deformation and must make its length longer. Therefore, the insertion amount of the cover body 2 inserted into the housing 1 becomes larger, so there is a limitation of the long insertion amount of the device. Problems with the installation of the wiring board inside the housing
[0013] In addition, when the control panel is installed, it is necessary to confirm the display content while performing necessary operations on the temperature regulator installed in the housing 1 from the front of the control panel, so it is necessary to collectively arrange the operation part and the display part on the cover body. 2, however, as mentioned above, in the case of the existing casing, there is a large dead space between the side end 20b of the seat ring portion 20 and the baffle piece 4, and as a result, the opening portion 10 of the cover body 2 It is difficult to reduce the size of the cover body 2 while concentrating the operation part and the display part on the front of the cover body 2.

Embodiment Construction

[0020] An embodiment of the present invention will be described below.

[0021] exist figure 1 and figure 2 Among them, 11 is a front square housing that becomes the main body of a thermostat or the like, one end surface of which is open, and the other end surface is a closed end surface. The casing 11 is formed with an elastic piece that is integrally formed with the casing 11 and can be elastically deformed instead of a portion extending from a part of the flange portion 11a forming the periphery of the opening 15 to a part of one side of the casing. 12. Two slots 12a are provided between the elastic piece 12 and the above-mentioned one side of the casing. Therefore, the elastic piece 12 can elastically deform toward the center of the opening 15 of the housing 11 with the portion 12b between the ends of the two cutouts 12a as a fulcrum. In addition, at the free end portion of the elastic piece 12 near the opening end of the housing 11, an outward anti-seismic portion 1...

Abstract

Disclosed is a shell provided with a dismountable cover. An elastic strip is formed at the part from a flange part along the edge of an opening part of the shell to one side surface and is integrally molded with the shell. The elastic strip can be elastically deformed towards the center direction of the opening part of the shell. An outward anti-separation part with a bevel is integrally molded with the elastic strip, on the free end of the elastic strip; a projection for pressing is projected towards the outside of the shell and integrally molded with the elastic strip, at one side of the outward anti-separation part and close to the closed end face. According to the structure, the problem that the space for baseplate arrangement between a jogged plate and a baffle plate is narrowed because of big deformation degree of the elastic strip when the cover is taken off from the current apparatus is solved.

Description

technical field [0001] The present invention relates to a case for a measuring instrument having a detachable cover, and is very suitable for, for example, a case of a temperature regulator mounted on a control panel. Background technique [0002] image 3 (a), (b) are the oblique views of existing housings with foldable covers, Figure 4 for image 3 (b) B-B sectional view. In the figure, 1 is a casing of a housing such as a thermostat, and 2 is a cover attached to an opening of the casing 1 . On the back of the cover body 2 are formed a protruding and parallel fitting piece 3 , a baffle piece 4 and an elastic piece 5 . [0003] The fitting piece 3 protrudes toward the case 1 at a position slightly inside the side end 20 a of the race portion 20 on the cover 2 , thereby constituting a fitting portion corresponding to the race portion 1 a of the case 1 . The baffle piece 4 is provided so as to face the fitting piece 3 across the opening 10 of the cover body 2 and to be po...
