Business board described in the utility model inserts guider, comprise guiding needle guard and guide pin, described guide pin puts and is provided with more than one location hole and the some and vertically disposed bolt hole of location hole, and described guiding needle guard is fastened and is connected with business board by the bolt on bolt hole;
Described guide pin comprises positioning end and stiff end, is provided with location baffle ring between described positioning end and stiff end; The positioning end of described guide pin is the cylinder coordinating with location hole, and described stiff end is provided with screw thread, and described stiff end is by being fixed and being arranged on backboard with nut.
Further, on described location hole, be provided with the chamfering of convenient location, lead more convenient.
Further, the positioning end of described guide pin is provided with the chamfering that conveniently enters location hole, locates more convenient.
Further, more accurate in order to locate, described location hole inner surface is smooth, and its roughness is Ra1.6～Ra6.3, preferably Ra3.2.
Further, more accurate in order to locate, the positioning end smooth surface of described guide pin, its roughness is RA1.6～Ra6.3, preferably Ra3.2.
Further, cause getting loose of guider in order to prevent from repeatedly plugging, described guide pin stiff end and backboard link position are provided with the screw thread glue that prevents that bolt from getting loose.
Further, to cause getting loose of guider in order preventing from repeatedly plugging, on described guiding needle guard bolt hole, to be provided with the screw thread glue that prevents that bolt from getting loose.
Further, in order to adapt to the business board of plurality of specifications function, described location hole is two.
Further, described guide pin and guiding needle guard are that aluminum alloy materials is made, and material is light, is convenient to transport.
Compared with prior art, the beneficial effects of the utility model are:
The utility model business board that effectively precisely leads, the smoothness of matching surface ensures that the plug of business board is smooth and easy, well improves user's experience; The fixed screw that this business board inserts in guider is equipped with screw thread glue, the inefficacy that gets loose that can prevent business board repeatedly to plug to cause.In addition, the utility model fabrication technology is simple, cheap, convenient transport.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the structural representation that business board described in the utility model is plugged in guider;
Fig. 2 is the use view that business board described in the utility model is plugged in guider.
In figure: the 1-needle guard that leads, 11-bolt hole, 12-locates chamfering, 13-location hole, 2-guide pin, 21-stiff end, 22-chamfering, 23-positioning end, 24-locates baffle ring, 3-backboard, 31-nut, 32-fixing hole, 4-business board, 41-bolt, 42-installing hole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Fig. 1～Fig. 2, business board described in the utility model inserts guider, comprise be fixed on the needle guard 1 that leads on business board 4, with the guide pin 2 that the needle guard 1 that leads coordinates, described guide pin 2 is fixed on backboard 3.
On described guiding needle guard 1, be provided with two location holes 13 and four bolts hole 11 for being fixedly connected with business board 4, described location hole 13 is not limited to two, can be one, three or more, described bolt hole 11 be not limited to four, can be two, three or more.Described location hole 13 and the mutual vertical setting of bolt hole 11, this location hole 13 is provided with the location chamfering 12 that facilitates guide pin to insert.
The positioning end 23 that described guide pin 2 comprises the stiff end 21 fixing with base plate 3 and coordinates with the location hole 13 of guiding needle guard, between described stiff end 21 and positioning end 23, be provided with location baffle ring 24, on the end face of described positioning end 23, be provided with chamfering 22, described stiff end 21 is provided with screw thread.
