SUMMERY OF THE UTILITY MODEL
The utility model provides a working of plastics fixed knot constructs with locate function aims at solving and is not connected with the location on the current screw rod and mediates to can not play the positioning action, and bury the problem that the working of plastics in the board is difficult to the expansion.
The utility model discloses a realize like this, a working of plastics fixed knot constructs with locate function, including being used for making the working of plastics body subassembly that rises, the body subassembly includes screw rod, working of plastics body and outer pawl matrix, the screw rod is located the inside of working of plastics body, just the screw rod with working of plastics body spiro union, outer pawl matrix is located the bottom of working of plastics body, just outer pawl matrix with the fixed intercommunication of working of plastics body, the breach has on the outer pawl matrix, the width of breach is less than the width of screw rod, the cover is equipped with the location and mediates on the lateral wall of screw rod, just the location mediate with screw rod fixed connection.
Preferably, the interior of the plastic part body is provided with a threaded hole, and the threaded hole penetrates through the plastic part body and is communicated with the external tooth matrix.
Preferably, the positioning member has an annular shape.
Preferably, the top end of the screw is provided with a connecting piece.
Preferably, the connecting member is spherical.
Compared with the prior art, the beneficial effects of the utility model are that: by arranging the positioning medium, when a worker twists the screw rod, the positioning medium on the screw rod cannot continuously sink after contacting the plastic part body, so that a good limiting effect is achieved;
through setting up outer pawl matrix, when the tip of screw rod stretches into on the outer pawl matrix when in the breach, the breach is propped open, thereby makes outer pawl matrix inflation makes outer pawl matrix fully contacts with the panel.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-2, a plastic part fixing structure with a positioning function includes a body assembly 1 for expanding a plastic part, the body assembly 1 includes a screw 11, a plastic part body 12 and an external inverted tooth matrix 13, the screw 11 is located inside the plastic part body 12, the screw 11 is screwed with the plastic part body 12, the external inverted tooth matrix 13 is located at the bottom of the plastic part body 12, the external inverted tooth matrix 13 is fixedly communicated with the plastic part body 12, the external inverted tooth matrix 13 is provided with a notch 14, the width of the notch 14 is smaller than that of the screw 11, a positioning medium 15 is sleeved on the outer side wall of the screw 11, and the positioning medium 15 is fixedly connected with the screw 11.
In the present embodiment, by providing the screw 11, the screw 11 is rotated and lowered inside the plastic body 12 until entering the external undercut matrix 13; by arranging the plastic part body 12, the plastic part body 12 supports the external inverted tooth matrix 13 and also provides support for the screw 11; by arranging the external tooth matrix 13 and the gap 14 to be smaller than the width of the screw 11, wherein the external tooth matrix 13 has certain elasticity, when the end part of the screw 11 extends into the gap 14 on the external tooth matrix 13, the gap 14 is spread, so that the external tooth matrix 13 is expanded, and the external tooth matrix 13 is fully contacted with the plate; through setting up the location and mediating 15, when location mediate 15 and working of plastics body 12 contact, screw rod 11 can not continue to sink to play good limiting displacement.
Further, the interior of the plastic body 12 has a threaded hole 16, and the threaded hole 16 penetrates through the plastic body 12 and communicates with the external tooth matrix 13.
In the present embodiment, the screw 11 is screwed with the plastic body 12 through the threaded hole 16 by providing the threaded hole 16, wherein the threaded hole 16 is matched with the screw 11.
Further, the positioning member 15 has an annular shape.
In the present embodiment, the positioning medium 15 is annular, so that the positioning medium 15 having this shape can sufficiently contact with the plastic body 12, and the downward movement of the screw 11 is effectively restricted.
Further, a connecting piece 17 is installed at the top end of the screw rod 11.
In this embodiment, by providing the connecting member 17, the worker can conveniently rotate the screw 11 through the connecting member 17.
Further, the connecting member 17 is spherical.
In the present embodiment, the spherical shape of the coupling member 17 increases the contact area with the palm of the worker, and the screw 11 can be rotated more easily.
In summary, the worker first puts the plastic body 12 into the perforated furniture board, then rotates the screw 11, so that the screw 11 descends while rotating in the plastic body 12 until the positioning medium 15 on the screw 11 contacts with the upper surface of the plastic body 12, at this time, the screw 11 does not sink any more, the end of the screw 11 extends into the notch 14 on the external inverted tooth matrix 13, and the notch 14 is opened, so that the external inverted tooth matrix 13 expands, and the external inverted tooth matrix 13 fully contacts with the board. Through above-mentioned subassembly, both can carry out spacingly to screw rod 11, can make the working of plastics expand again.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
