Description
Technical field
The utility model relates to a kind of combined environment testing equipment, and in particular to a kind of vibration test wall hanging test specimen folder
Tool.
Background technique
Vibration test refers to evaluation product vibration resistance and the test that carries out, folder of tested products in expected use environment
Tool is the link that must be taken into consideration in preparation process before testing, and fixture has been the transition piece of connection or switching, and the quality of fixture is directly
Influence the quality that test carries out.
For all kinds of wall hanging test specimens, such as power supply box, display screen be when carrying out reliability test, to shorten test period,
The scheme usually tested simultaneously using multiple samples, sample size is mostly 4.In view of assembly space, cable arrangement, sample institute
The three combined test chamber areas occupied should not be too large, but traditional fixture for wall hanging test specimen is inverted T shaped tooling, and structure is as schemed
It is sufficiently bulky shown in 1, it takes up a large area.
Summary of the invention
The utility model aim is to provide a kind of vibration test wall hanging piece fixture, before guaranteeing first order resonance frequency
Put the volume for reducing fixture.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of vibration test wall hanging piece fixture,
Including rectangle top frame, rectangle bottom frame and four columns, rectangle top frame and rectangle bottom frame are oppositely arranged in parallel up and down, four columns
It is connected between rectangle top frame and the corner of rectangle bottom frame, makes fixture in a frame-shaped cube with this；Also, the rectangle top frame
Four diagonal braces are additionally provided between rectangle bottom frame, for this four diagonal braces with the center rotational symmetry of bottom frame, the top of each diagonal brace is solid
Surely the corner of rectangle top frame is connected, bottom end is fixedly connected with the center of rectangle bottom frame；The side of the surrounding of the frame-shaped cube
It is equipped with test specimen and hangs position.
In above scheme, on the surrounding side of the corresponding frame-shaped cube, more are connected between the adjacent column
Crosspiece also is provided with vertical connecting rod between rectangle top frame and rectangle bottom frame.
In above scheme, the rectangle top frame is by rectangle overlapped four edge strips and ten inside four edge strips
Font overlapped connecting rod is constituted.
In above scheme, the rectangle bottom frame is by rectangle overlapped four edge strips and the well inside four edge strips
Font overlapped connecting rod is constituted.
Since the utility model uses cube-shaped structure, test specimen is hung on the surrounding side of cube, with existing T-type
Tooling is compared, and similar first order resonance frequency can be reached, and volume is only the 39.9% of existing T-type tooling, is had obvious excellent
Gesture.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment: referring to fig. 2 shown in -4:
A kind of vibration test wall hanging piece fixture, referring to fig. 2 shown in -4, including rectangle top frame 1, rectangle bottom frame 2 and
Four columns 3, rectangle top frame 1 and about 2 rectangle bottom frame are oppositely arranged in parallel, and four columns 3 are connected to rectangle top frame 1 and rectangle
Between the corner of bottom frame 2, make fixture in a frame-shaped cube with this.
Referring to fig. 2 shown in -4, four diagonal braces 4 are additionally provided between the rectangle top frame 1 and rectangle bottom frame 2, this four diagonal braces 4
With the center rotational symmetry of rectangle bottom frame 2, the top of each diagonal brace 4 is fixedly connected with the corner of rectangle top frame 1, and bottom end is fixed to be connected
Connect the center of rectangle bottom frame 2；The side of the surrounding of the frame-shaped cube is equipped with test specimen and hangs position 5.
Referring to fig. 2 shown in -4, on the surrounding side of the corresponding frame-shaped cube, it is connected between the adjacent column 3
More crosspieces 6 also are provided with vertical connecting rod 7 between rectangle top frame 1 and rectangle bottom frame 2.
Referring to fig. 2 shown in -4, the specific rectangle top frame 1 is by rectangle overlapped four edge strips 11 and being set to four sides
Overlapped that connecting rod 12 is constituted for cross inside item 11.
Referring to fig. 2 shown in -4, the specific rectangle bottom frame 2 is by rectangle overlapped four edge strips 21 and being set to four sides
Overlapped that connecting rod 22 is constituted for groined type inside item 21.
