Description

Clamshell sound proof box

Technical field

The utility model relates to acoustical testing field more particularly to a kind of clamshell sound proof boxs.

Background technique

Sound proof box is mainly used for the audio-frequency test of the wireless telecommunications systems such as mobile phone, and sound insulation index request is high, sound insulation box enclosure It is welded using Metal plate, appearance is sprayed with environmental protection paint facing, and box inside uses shock insulation sound-absorbing material, and sound insulation chamber door side has Foot pad is sealed, rear interface board provides detection environment equipped with cable interface etc., predominantly product noise measuring.

The mode of operation of most sound proof box is all from front opening structure in the market, and front opening structure space is smaller, because This can not play the acoustic-electric product that some flow line productions are tested and provide quick access for and test, and testing efficiency is low.

Utility model content

The utility model is proposed in view of the above problem of the existing technology, the utility model provide a kind of cabinet from The high clamshell sound proof box of dynamic folding, good seal performance, testing efficiency.

The utility model is achieved through the following technical solutions: a kind of clamshell sound proof box comprising upper box, nowel Body, hinge are equipped with insulation material layer in the upper box and lower box, solid by hinge between the upper box and lower box Fixed connection；The upper box and lower box closure contact position are inclined surface.

Preferably, the inclined surface includes that fit structure is sealed against each other between the upper box and the lower box, described Sealing fit structure is made of acoustic material.

Further, the tilt angle of the inclined surface is 20~70 degree.

Preferably, the hinge is located at the high-end of the inclined surface.

Further, the hinge is located at the low side of the inclined surface.

It preferably, further include cylinder, one end of the cylinder is articulated with the lower box, and the other end of the cylinder is hinged In the upper box.

Further, the cylinder is equipped with two groups, and is located at the upper box two sides.

It preferably, further include mounting rack, the lower box is mounted on the mounting rack.

Further, the mounting rack is equipped with safe spacing structure, and the safe spacing structure is connected to upper box.

Preferably, display is additionally provided on the mounting rack.

Compared with prior art, the utility model is provided with upper and lower cabinet, and between upper and lower cabinet using inclined surface into Row contact sealing, effectively increases contact area when upper and lower cabinet is closed, while in the effect of upper box self gravity Under, upper box to improve the compactness of upper and lower box contact, and then is effectively mentioned by the compression lower box of inclined surface tightly The soundproof effect of high sound proof box can guarantee the test environment of box house sound insulation value 36dB (A)；Using the side of upper and lower box Formula, the taking-up and deposit of more convenient testing element effectively improve the utilization rate of sound proof box, and then improve testing efficiency；It adopts The opening and closing of cabinet are carried out with cylinder, reduce required manpower in test process, reduce production cost, and cylinder melts automatically It opens and closes, effectively improve testing efficiency.

Specific embodiment

In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figure 2, Figure 3, Figure 4, a kind of clamshell sound proof box comprising upper box 38, lower box 37, hinge 36, peace It shelves, the lower box is mounted on the mounting rack, and insulation material layer 34 is equipped in the upper box and lower box, described It is fixedly connected between upper box 38 and lower box 37 by hinge 36；The upper box 38 is closed contact position with the lower box 37 For inclined surface 33, handle 39 is equipped at the upper box 38.

The inclined surface 33 includes that fit structure 32 is sealed against each other between the upper box 38 and the lower box 37, described Sealing fit structure 32 is made of acoustic material.Wherein, it should be noted that sealing fit structure 32 includes upper and lower box two Part is constituted, and the specific way of realization for sealing fit structure is not particularly limited, either being arranged to mutual cooperation tongue and groove Structure can also be sealed by the way of interference fit.

Wherein, the tilt angle of the inclined surface 33 is 20~70 degree, preferably 45 °, at this point, above and below between cabinet Contact area is larger, and upper box itself also forms good sealing enough, while upper box is easy to open.

In addition, being additionally provided with display 5 on the mounting rack 1, the display 5 is for showing test product and cabinet ginseng Number.

In order to more use sound proof box safely, the opening and closing place between the cabinet is equipped with safe grating 2, the safe grating 2 are mounted on the mounting rack 1.

Embodiment one

As shown in Fig. 2, the hinge 36 is located at the high-end of the inclined surface 33, upper box point each to inclined surface has at this time Sufficient pressing force, is capable of forming good sealing, effectively increases the sealing effect of cabinet.

Embodiment two

The hinge is located at the low side (embodiment is not shown in the figure) of the inclined surface, and the center of gravity of upper box is leaned at this time At nearly hinge, the unlatching of upper box is relatively labor-saving, easy to use.

Embodiment three

With embodiment one or two the difference is that: further include cylinder 5, one end of the cylinder 5 is articulated with the nowel Body 37, the other end of the cylinder 5 are articulated with the upper box 28.

As shown in Fig. 2, the cylinder is equipped with two groups, and it is located at the upper box two sides.

It is provided with cylinder, the automatic open-close of upper box may be implemented, effectively improve working efficiency, is convenient for sound proof box application In being used in production line.

Example IV

With embodiment three the difference is that: the mounting rack be equipped with safe spacing structure 4, the safe spacing knot Structure 4 is connected to upper box 38.

As shown in fig. 6, the safe spacing structure includes locating oil cylinder 42, limit sliding bar 43, limit hinged end 44, institute Stating locating oil cylinder 42 drives the limit sliding bar 43 to be moved forward and backward, and the limit hinged end 44 is articulated with the limit sliding bar 43。

As shown in figure 5, the upper box 38 is equipped with hinged seat 31, the one of the cylinder 5 is articulated on the hinged seat 31 End, the limit hinged end 44 is connected in the hinged seat 31.

In use, stretching or retraction by locating oil cylinder, the position of auxiliary control upper box, are effectively prevented cylinder 5 When abnormal, upper box emergency cut-off due to gravity causes unnecessary loss.

The utility model is not limited to above embodiment, if the various changes or deformation to the utility model do not take off Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model Within the scope of, then the utility model is also intended to encompass these changes and deformation.
