when a drive plate on the existing market is clamped, the stress on two sides of the drive plate is uneven, so that the condition that the drive plate is deviated in the clamping detection process is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defect that the driving plate is deviated in the clamping detection process due to the fact that stress on two sides of the driving plate is uneven in the prior art, and provides a lamp driving plate test fixture.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a lamps and lanterns drive plate test fixture, includes the support frame, the through-hole has been seted up to the upper end of support frame, the through-hole top is inserted and is equipped with and runs through the electric telescopic handle of through-hole, electric telescopic handle's lower extreme horizontal installation has the connecting plate, the vertical bracing piece of installing in the lower extreme both sides of connecting plate, articulated ware is installed to one side lower extreme of support frame, articulated in the articulated ware have two dwangs that mutual symmetry set up, one side upper end of dwang has all been seted up and has been run through the slotted hole of dwang, the equal vertical bracing piece of installing in the lower extreme both sides of connecting plate, the lower extreme horizontal installation of bracing piece has the cylinder, two the cylinder slides respectively and sets up at the slotted hole inboard of difference, two the equal fixed mounting of relative one side lower extreme of dwang has splint.

Preferably, the middle parts of the two opposite sides of the clamping plates are provided with V-shaped grooves.

Preferably, two the relative one side of splint evenly is provided with a plurality of arch, the arch is the arc form setting.

Preferably, the support frame is arranged in an L shape.

Preferably, the size of the slot is matched with that of the column

The lamp driving board test fixture provided by the utility model has the beneficial effects that: this lamps and lanterns drive plate test fixture along with the regulation of electric telescopic rod's length to effectual realization is to the regulation of two dwang angles, thereby carries out the centre gripping to the drive plate to the splint that two symmetries set up, and the both sides atress of drive plate is even, thereby the effectual realization is to the detection of drive plate.

Fig. 1 is a structural front view of a lamp driving board testing fixture according to the present invention.

Fig. 2 is a structural side view of a lamp driving board testing fixture according to the present invention.

Fig. 3 is a top view of a structure of a lamp driving board testing fixture according to the present invention.

In the figure: electric telescopic rod 1, through-hole 2, support frame 3, connecting plate 4, bracing piece 5, slotted hole 6, cylinder 7, articulated ware 8, splint 9, arch 10, V type groove 11, dwang 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1

Referring to fig. 1-3, a lamp driving plate test fixture comprises a support frame 3, a through hole 2 is formed in the upper end of the support frame 3, the support frame 3 is in an L-shaped arrangement, an electric telescopic rod 1 penetrating through the through hole 2 is inserted above the through hole 2, the electric telescopic rod 1 is connected with a power supply device through a wire, an external control switch is installed on the wire, and the support frame 3 is fixed on a frame body through a connecting piece.

The lower extreme horizontal installation of electric telescopic handle 1 has connecting plate 4, the vertical bracing piece 5 of installing in lower extreme both sides of connecting plate 4, articulated ware 8 is installed to one side lower extreme of support frame 3, articulated have dwang 12 that two mutual symmetries set up in the articulated ware 8, slotted hole 6 that runs through dwang 12 is all seted up to one side upper end of dwang 12, the equal vertical bracing piece 5 of installing in lower extreme both sides of connecting plate 4, the lower extreme horizontal installation of bracing piece 5 has cylinder 7, two cylinder 7 slide respectively to set up in the slotted hole 6 inboards of difference, and the size of slotted hole 6 matches each other with the size of cylinder 7, the equal fixed mounting of one side lower extreme relatively of two dwang 12 has splint 9, the theory of operation of this structure is: when the centre gripping is realized to the drive plate to needs, electric telescopic handle 1's length shrink, upwards lifting connecting plate 4 for cylinder 7 upwards slides in slotted hole 6 inboard, and two splint 9 of lower extreme of two dwang 12 draw close each other, realize line contact to the drive plate, thereby make the atress of drive plate both sides even, the more stable of centre gripping.
