Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides an anchor clamps that circuit board processing was used, is including the rectangle base 1 that transversely sets up, base 1 left and right sides is provided with horizontal slip opening 3 around all, wherein all is provided with L type grip block 4 that the back-off set up in every group slip opening 3, the opening of grip block 4 is located the setting towards base 1 left and right sides length direction's centre, connects through pull rod 5 between two sets of grip block 4 backs of homonymy around wherein, and wherein the horizontal end of grip block 4 is located base 1 top in this embodiment, and the vertical end of grip block 4 passes corresponding slip opening 3 and extends to base 1 bottom.

Then, the circuit board 2 with the length larger than the distance between the left and right sets of sliding openings 3 is placed on the base 1 between the left and right clamping blocks 4, and at the moment, the vertical end of the clamping block 4 can horizontally displace left and right in the sliding opening 3, so that the distance between the left and right clamping blocks 4 is changed, and the circuit board 2 with the corresponding size is clamped and fixed on the base 1. In the process, the pull rod 5 is convenient for pulling the two groups of clamping blocks 4 on the same side to move simultaneously, and the two groups of clamping blocks 4 form a whole to improve the stability of the clamping block.

Wherein transversely be provided with the fixed passage 10 that runs through corresponding sliding opening 3 on the base 1, and be provided with the through-hole 11 that corresponds fixed passage 10 on the grip block 4 to the base 1 outside sets up the U type pole 12 that both ends passed corresponding fixed passage 10 and through-hole 11 according to the preface, wherein lie in U type pole 12 both ends in the base 1 outside and all the spiro union has nut 13 on the pole body, and lie in the U type pole 12 pole of grip block 4 back and all overcoat have the push spring 14 that sets up in corresponding sliding opening 3.

In this embodiment, the through hole 11 and the vertical section of the fixing channel 10 are both hexagonal, wherein the size of the U-shaped rod 12 is matched with the size of the through hole 11 and the size of the fixing channel 10, both ends of the U-shaped rod 12 located outside the base 1 are both screw rod structures, and the nut 13 is fixed with the screw rod structures in the U-shaped rod 12 in a threaded manner.

When the circuit board 2 is installed, the through hole 11 is driven to slide freely on the rod body of the U-shaped rod 12 to prevent the through hole from sliding out of the sliding opening 3 by pulling the corresponding clamping block 4 outwards through the pull rod 5, as shown in fig. 2 in particular, so that the vertical end of the clamping block 4 is driven to move in the sliding opening 3, the through hole slides on the rod body of the U-shaped rod 12, and simultaneously the pushing spring 14 is squeezed to shrink, so that the space between the clamping blocks 4 on the left side and the right side is enlarged to facilitate the installation of the circuit board 2 between the clamping blocks 4 on the left side and the right side, and then the pull rod 5 is slowly loosened to enable the pushing spring 14 to stretch to push the vertical end of the clamping block 4 to move in the sliding opening 3, The through holes 11 slide on the U-shaped rods 12, so that the space between the left and right clamping blocks 4 is reduced to clamp and fix the circuit board 2 on the top of the base 1.

And in order to further strengthen the steadiness of the circuit board 2 on the base 1, make the left and right sides grip block 4 can be better fix the centre gripping of circuit board 2 on the base 1, as shown in fig. 1, 2, still be provided with the locating lever 6 in grip block 4 bottom, wherein control and connect through the spring 7 that drags that is located the base 1 below between two sets of corresponding locating levers 6, and drag spring 7 both ends and all be provided with the ring 8 of cover on corresponding locating lever 6, and still be provided with the lag 9 that will drag spring 7 to entangle in base 1 bottom in order to play the guard action to it.

When the pushing spring 14 is expanded to push the holding blocks 4 to move, so that the holding blocks 4 on the left and right sides play a role in holding and fixing the circuit board 2, the pulling spring 7 is contracted and pulls the holding blocks 4 on the two sides thereof through the positioning rod 6 to reduce the distance between the holding blocks 4, thereby further enhancing the stability of the circuit board 2 on the base 1.

Preferably, a rubber pad 15 is bonded to the inner side wall of the clamping block 4.

As a preferred scheme, scale marks 16 are engraved on the front side and the rear side of the top of the base 1 so that people can conveniently adjust the distance between the two groups of clamping blocks 4, and therefore people can conveniently place the circuit board 2 on the base 1 between the clamping blocks 4 on the left side and the right side.

The use method of the invention comprises the following steps: the pull rod 5 pulls the corresponding clamping block 4 outwards to move outwards, so as to drive the vertical end of the clamping block 4 to move in the sliding opening 3, the through hole 11 slides on the body of the U-shaped rod 12, the two groups of positioning rods 6 stretch the pulling spring 7 to stretch, and simultaneously extrude the pushing spring 14 to contract, thereby enlarging the space between the left and right clamping blocks 4 to facilitate the installation of the circuit board 2 between the left and right clamping blocks 4, then the pull rod 5 is slowly released, the push spring 14 is expanded to push the vertical end of the clamping block 4 to move in the sliding opening 3, the pull spring 7 is contracted to drive the vertical end of the clamping block 4 to move in the sliding opening 3, the through hole 11 slides on the rod body of the U-shaped rod 12, thereby reducing the space between the left and right clamping blocks 4 to clamp and fix the circuit board 2 on the top of the base 1, and improving the stability of the circuit board 2 on the base 1. And because the U-shaped rod 12, the push spring 14 and the pull spring 7 are respectively positioned in the base 1 or at the bottom of the base 1, the installation and removal work of the circuit board 2 on the top of the base 1 cannot be influenced, meanwhile, the nut 13 can be unscrewed, so that the U-shaped rod 12 is pulled out from the fixed channel 10, the ring 8 is pulled out from the positioning rod 6, the pull spring 7 is pulled out from the protective sleeve 9, and the clamping block 4 and the push spring 14 are pulled out from the sliding opening 3, so that the device is disassembled into a plurality of small parts for storage and transportation.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
