Abstract

The invention provides a compaction device which comprises a base plate, an ejection plate, a pushing column and a plurality of compaction arms. A central hole is arranged on the base plate, one end of the pushing column extends in the central hole and moves along the axial direction of the central hole, the other end of the pushing column extends outward to form a plurality of guide arms, one through hole is arranged at the end of the outer side of each guide arm, the plurality of guide arms are evenly distributed on the periphery of the pushing column, the number of the compaction arms is equal to that of the guide arms, and positions of the compaction arms correspond to positions of the guide arms. Each compaction arm penetrates through the through hole of one guide arm, one end of the compaction arm is hinged to the base plate, and the other end of the compaction arm is connected onto the ejection plate in overlapping mode through a transition portion. The compaction device moves along the axial direction of the central hole through the pushing column to drive the compaction arms to move inward or outward so as to achieve compaction and loosening of the ejection plate. The compaction device is simple and compact in structure, ingenious in design, convenient to operate and use, low in manufacturing cost and good in compaction effect.

Description

A kind of hold down gag

Technical field

The invention belongs to the anchor clamps field, be specifically related to a kind of hold down gag.

Background technology

The automatic print line of panel trade mark needed panel to be fixed before printing the panel trade mark, with the effect that guarantees to print.But present hold down gag is complicated structures all generally, and use cost is higher.

Summary of the invention

The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of hold down gag simple in structure, compact, with low cost is provided.

The present invention is achieved through the following technical solutions:

A kind of hold down gag is characterized in that, comprises substrate, top board, promotion post and a plurality of clamping arm, is provided with a centre bore on the described substrate; One end of described promotion post stretches in the described centre bore, and can move along the axis direction of described centre bore; The other end that promotes post extends outward a plurality of leading arms, and the outboard end of each leading arm is provided with a through hole, a plurality of leading arms be evenly distributed on promote post around; The number of clamping arm equates with the number of leading arm, and the position is corresponding; Each clamping arm all passes the through hole of a leading arm, and an end is hinged on the substrate, and the other end is overlapped on the top board by a turning point.

Further, the number of described clamping arm and leading arm is four.

Further, described substrate is square, and four clamping arms are hinged on four sides of substrate.

Hold down gag of the present invention inwardly drives clamping arm or outwards motion by promoting post along the moving of the axis direction of centre bore, thereby has realized the compression of top board and loosen; Hold down gag of the present invention is simple in structure, compact, designs ingeniously, operates easy to usely, cheap for manufacturing cost, compresses effective.

Description of drawings

Fig. 1 is the schematic perspective view of hold down gag of the present invention;

Among the figure: substrate-1, top board-2 promotes post-3, clamping arm-4, centre bore-5, leading arm-6, through hole-7, turning point-8.

The specific embodiment

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the invention provides a kind of hold down gag, comprise substrate 1, top board 2, promote post 3 and a plurality of clamping arm 4, be provided with a centre bore 5 on the described substrate 1; One end of described promotion post 3 stretches in the described centre bore 5, and can move along the axis direction of described centre bore 5; The other end that promotes post 3 extends outward a plurality of leading arms 6, and the outboard end of each leading arm 6 is provided with a through hole 7, a plurality of leading arms 6 be evenly distributed on promote post 3 around; The number of clamping arm 4 equates with the number of leading arm 6, and the position is corresponding; Each clamping arm 4 all passes the through hole of a leading arm 6, and an end is hinged on the substrate 1, and the other end is overlapped on the top board 2 by a turning point 8.

Have external force upwards to act on when promoting post 3, promote post 3 and move upward, clamping arm 4 is under the effect of leading arm 6, and to the inside motion compresses top board 2; Have external force to act on when promoting post 3 downwards, promote post 3 and move downward, clamping arm 4 is under the effect of leading arm 6, and top board 2 is unclamped in motion laterally.

Preferably, the number of described clamping arm 4 and leading arm 6 is four, and described substrate 1 is square, and four clamping arms 4 are hinged on four sides of substrate 1.The number of certain clamping arm of the present invention 4 and leading arm 6 is not limited to this, can also adopt according to actual needs two, three or more.
