[0021] Example

[0022] Reference Figure 1-2As shown, the utility model discloses an instrument housing with an elastic hook 101, including a main body, the main body including a box body 20 and a panel 10, the elastic hook 101 is installed on both sides of the main body, one end of the elastic hook 101 is fixed to the panel 10, and the other end is close to the side wall of the box body 20, wherein the main body and the elastic hook 101 are integrally formed, which can improve the production efficiency of the instrument housing, and one end of the elastic hook 101 is fixed and the other end is free to move, leaving space for deformation. And the side of the elastic hook 101 close to the box body 20 is in a wedge shape, that is, the tail of the elastic hook 101 is in a wedge shape, which is convenient for the housing to be inserted from the opening of the chassis cabinet plate, and will not be stuck on the side of the opening of the chassis cabinet plate.

[0023] Reference Figure 1-2 As shown, the end of the spring hook 101 close to the fixed end protrudes toward the side away from the box body 20 to form a protrusion 1012, and the spring hook 101 is bent between the protrusion 1012 and the panel 10 toward the side of the box body 20 to form a bending portion 1013. The setting of the bending portion 1013 makes the protrusion 1012 close to the box body 20, so that the spring hook 101 can be better inserted into the opening of the chassis cabinet plate. The spring hook 101 is provided with a plurality of stepped teeth 1011 between the protrusion 1012 and the bending portion 1013. Specifically, when installing the instrument housing, the box body 20 is inserted from the opening of the chassis cabinet plate, and the tail of the spring hook 101 is gradually compressed and deformed by the chassis cabinet plate, and the protrusion 1012 of the spring hook 101 is compressed inward until it passes through the opening of the chassis cabinet plate and then quickly rebounds, and the front stepped teeth 1011 are clamped with the cabinet plate, so that the embedded instrument housing can be fixed on the chassis cabinet plate. Furthermore, the box body 20 has grooves 201 on both sides of the spring hook 101 . When the spring hook 101 is compressed, the bending portion 1013 will move closer to one side of the box body 20 , and the grooves 201 provide deformation space for the bending portion 1013 .

[0024] The spring hook 101 is made of ABS+PC material. The front end of the spring hook 101 supports the chassis panel 10, and the elastic deformation is large, and it is in a deformed state for a long time, which has high requirements for plastic materials. It is made of ABS+PC material, and the flexibility and fatigue resistance are greatly enhanced. At the same time, the deformation of the elastic structure is adjusted, and it is not easy to deform and break even in the case of vibration.

[0025] In addition, the panel 10 is further provided with avoidance grooves 102 at both ends along the length direction. Since the spring hook and the main body are formed by an integral injection molding process, the avoidance grooves provide avoidance space when the mold for forming the spring hook is demoulded.

[0026] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
