A kind of communication equipment protecgulum of the utility model, comprise main frame, described main frame is offered display screen mouth has been installed, described display screen is installed mouth upper end and has been offered receiver open holes, described display screen is installed the lower end of mouth and has been offered button open holes, it is coated with soft balsam material arround described main frame outer upper end and there is the shell protecting described main frame effect, the outer surface of described shell is circular arc shape, described receiver open holes interior periphery is provided with the platform of height lower than described main frame upper surface, the difference of altitude of described platform and described main frame upper surface is 0.1-0.2mm.

Further, the installation end of described main frame is provided with assembling angle, and described assembling angle is for ease of carrying out the C type assembling angle of the demoulding and assembling.

Further, the back of described main frame is provided with the injection moulding nut for fixed telecommunication equipment supporter, and described injection moulding nut does not exist the molten heavy stand of heat.

Further, described main frame upper periphery is used for the groove connect with described shell card, and the outer wall thickness of described groove is 0.48-0.52mm.

Further, there is the plane of a wide 0.48-0.52mm in the described main frame being positioned at described assembling angle place, the outside surface of described plane is coated with described shell.

Further, the sidewall of the lower end of described main frame becomes certain angle of inclination, and described angle of inclination is 87.1-87.9 ��.

A kind of communication equipment protecgulum of the utility model, compared with prior art has the following advantages:

The first, this communication equipment protecgulum is provided with the shell of soft balsam material, the main frame of communication equipment is had provide protection by this shell, it is possible to effectively avoid communication equipment to break the generation of phenomenon because of born; The outer surface of described shell is that circular arc shape can reach demoulding effect easily; And described receiver open holes interior periphery is provided with the platform of height lower than described main frame upper surface; the difference of altitude of described platform and described main frame upper surface is 0.1-0.2mm; this is also to be convenient in demoulding; if difference of altitude is excessive, can cause and fill material difficulty, if height was gone on business little, receiver protection net can be not easily installed.

2nd, the structure of the injection moulding nut of this communication equipment protecgulum does not have the molten heavy stand of heat, and this is that the injection moulding demoulding is convenient on the one hand, it is to increase the yield rate of communication equipment protecgulum; It is the selection for the ease of bolt model on the other hand, this injection moulding nut is mated more well with respective bolt.

3rd, the sidewall of the lower end of described main frame of this communication equipment protecgulum is certain pitch angle, convenient when this design makes to carry out stripping operation; This angle size is 87.1-87.9 ��, why adopts this angle one to be convenient in order to coordinate with the assembling of communication equipment bonnet etc., and two is in order to more comfortable when user holds communication equipment, and three is in order to communication equipment profile is more attractive in appearance.

Embodiment

Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.

As shown in figs 1-9, a kind of communication equipment protecgulum, comprises main frame 3, described main frame 3 has been offered display screen and has installed mouth 4. Described display screen is installed mouth 4 upper end and has been offered receiver open holes 1. Described display screen is installed mouth 4 times ends and has been offered button open holes 5. It is coated with soft balsam material arround described main frame 3 outer upper end and there is the shell 2 of protection described main frame 3 effect. Can effectively avoid communication equipment to be damaged because of born like this, extend the work-ing life of communication equipment. More smooth for the ease of demoulding during described shell 2 injection moulding, so the outer surface of described shell 2 is circular arc shape. In view of the needs that receiver protection net is installed, so described receiver open holes 1 interior periphery is provided with the platform of height lower than described main frame 3 upper surface, to hold the protection net of this receiver. The difference of altitude of described platform and described main frame 3 upper surface is c; wherein c is 0.1-0.2mm; this size can meet the demand that this receiver protection net is installed, and easily fills material when can ensure again injection moulding, additionally it is possible to ensures the demoulding smoothly of shell 2 described in this communication equipment.

The installation end of described main frame 3 is provided with assembling angle 7, and described assembling angle 7 is for ease of carrying out the C type assembling angle of the demoulding and assembling. The back of described main frame 3 is provided with the injection moulding nut 6 for fixed telecommunication equipment supporter, and described injection moulding nut 6 does not exist the molten heavy stand of heat. This is mainly convenient in order to the injection moulding demoulding, thus improves the yield rate of communication equipment protecgulum; Secondly, it is the selection in order to facilitate bolt model, this injection moulding nut 6 is mated better with respective bolt.

Described main frame 3 upper periphery is used for blocking the groove connect with described shell 2, and the outer wall thickness of described groove is d, and wherein d is 0.48-0.52mm. If the outer wall thickness of this groove is crossed little, not easily fill material, thus cause producing, because product lacks material, the phenomenon that product structure is imperfect, make the decrease in yield of this communication equipment protecgulum; Then cannot matched well install with described shell 2 if the outer wall thickness of this groove is excessive.

The described main frame 3 being positioned at described assembling angle 7 place exist one wide for a depression end face 8, this is that wherein a is 0.48-0.52mm for the ease of installing the function key such as volume key, on & off switch. It is to improve this communication equipment stopping property that the outside surface of described plane is coated with described shell 2, makes this communication equipment have good dust-proof effect.

For the ease of the demoulding of described main frame 3, so the sidewall of described main frame 3 times ends becomes certain angle of inclination. Described angle of inclination is b, and wherein b is 87.1-87.9 ��, and in the present embodiment, b is 87 ��. Why adopt this angle to be first convenient in order to coordinate with the assembling of communication equipment bonnet etc., secondly it be in order to more comfortable when user holds communication equipment, be finally in order to communication equipment profile is more attractive in appearance.

Above an embodiment of the present utility model is described in detail, but described content is only better embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model. All equalizations done according to the utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
