Description
Technical field
The utility model relates to a kind of light fixture detection device, specifically a kind of light fixture electromagnetic compatibility Bracket for Inspection.
Background technology
When the electromagnetic compatibility carrying out light fixture detects, in order to ensure the accuracy that electromagnetic compatibility detects, need the support adopting wood or low conducting plastics to make to be fixed in three loop antennas by light fixture to be measured, and the geometric center of light fixture must be consistent with the center of three loop antennas.And due to different light fixture profiles to be measured different, being therefore usually preparing to the full solid-wood table of multiple different height in the lab, just can regulating the height of light fixture in certain limit by being stacked up up and down with different array modes by these desks.But such support exists the shortcoming that degree of regulation is lower, time-consuming and adjustment workload is larger, the demand that light fixture detects cannot be met, be further improved.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, and provide a kind of adjustable for height light fixture electromagnetic compatibility detection support, this support should be able to adjust the height of light fixture to be measured rapidly and accurately, and have the easy to operate and simple feature of structure.
The technical solution of the utility model is: a kind of adjustable for height light fixture electromagnetic compatibility detection support, comprise base, for placing light fixture to be measured and being positioned at the support platform above base, it is characterized in that: between described base and support platform, be provided with the adjustment structure that at least one can adjust support platform height;
Described adjustment structure comprises and is vertically arranged in base top surface and up big and down small taper compressing hole, is vertically fixed on below support platform and the slide bar interted downwards in described taper compressing hole and being arranged between compressing hole and slide bar for limiting the compressing sleeve of oppressing hole and slide bar relative position.
The axis projection of described compressing sleeve is annular, the external diameter fit of its internal diameter and slide bar and oppress on sleeve and be shaped with an axially through opening.
The lower outside of described compressing sleeve is shaped with and oppresses the matched taper stress surface of hole internal conical surface.
Described base and support platform adopt wood materials or low conducting plastic material to make.
Described compressing sleeve adopts wood materials, bamboo material or low conducting plastic material to make.
The quantity of described adjustment structure is 1-3.
The beneficial effects of the utility model are:
Adjustment structure of the present utility model have employed wedge self-lock mechanism, accurately can be adjusted the distance of in the vertical direction between support platform and base by this adjustment structure, and the geometric center of light fixture can be consistent with the center of three loop antennas; Meanwhile, structure of the present utility model is simple, and firm position, operates also very easy.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, a kind of adjustable for height light fixture electromagnetic compatibility detection support, comprises base 1, support platform 2 and adjustment structure; Described base and support platform adopt wood materials or low conducting plastic material to make, and support platform can vertically be positioned at above base slidably; As shown in Figure 5, three loop antennas 8 are fixed by bracing frame 81, and light fixture 9 to be measured to be placed in support platform and to be positioned at the center of three loop antennas.
The adjustment structure that at least one can adjust support platform height is provided with between described base and support platform; This adjustment structure with the slide bar (i.e. feet) below support platform for core formed, therefore the quantity of described adjustment structure is determined according to the quantity of slide bar, be generally 1-3 (1 adjustment structure is set in embodiment 1,3 adjustment structures are set in embodiment 2).
Described each adjustment structure comprise be formed on base top surface 12 taper compressing hole 11 (the large nose end in compressing hole is upwards arranged), be vertically fixed on slide bar 21 below support platform and compressing sleeve 3; Described slide bar downwardly towards under intert in compressing hole, and oppress sleeve and to be set on slide bar and to be positioned between compressing hole and slide bar and oppress hole and slide bar relative position to limit.
The axis projection of described compressing sleeve is annular, the compressing internal diameter of sleeve and the external diameter fit of slide bar, the periphery of simultaneously oppressing sleeve is shaped with an axially through opening 32 (opening plays the effect at expansion joint), the bottom of simultaneously oppressing sleeve is shaped with and oppresses the matched taper stress surface 31 of hole internal conical surface; Described compressing sleeve adopts wood materials, bamboo material or plastic material to make, and therefore oppresses sleeve and has certain deformability; The internal diameter (A/F on compressing sleeve is corresponding to be reduced) that can reduce to oppress sleeve by exerting pressure to the stress surface of compressing sleeve, makes the inner peripheral surface of oppressing sleeve be close on the outer circumference surface of slide bar.
Using method of the present utility model is:
1, light fixture to be measured is put support platform, the height of adjustment support platform makes the center of the geometric center of light fixture and three loop antennas be consistent;
2, pushed by the compressing sleeve be set on slide bar in compressing hole downwards, the stress surface of compressing sleeve will slide along compressing hole internal conical surface thus force the inner peripheral surface of compressing sleeve inwardly to shrink to clamp slide bar;
3, drive compressing sleeve continues to decline (due to the oppressed sleeve clamping of slide bar by support platform under gravity, therefore oppress between sleeve and slide bar and can produce enough stiction), make compressing sleeve clamp slide bar further, reach self-locking effect;
When 4, again adjusting the height of support platform, only upwards need lift support platform and just can remove self-locking state (support platform of rising will drive compressing sleeve to move up and exit compressing hole).
Claims (6)
