Abstract
The utility model provides a clamping bolt head, which comprises a wooden plane matrix and a splint vertical to the wooden plane matrix. The lower end of the splint is provided with a bolt head. The wooden plane matrix is provided with a trapezoidal clamping groove corresponding to the bolt head. The wooden plane matrix can be firmly connected with the vertical splint vertical. The vertical splint is difficult to fall down.
Description
Technical field
The utility model relates to a kind of clamping bolt head.
Background technology
In casting process, need use wooden model usually, when making wooden model, can run into the situation that on the parent of wooden plane, to fix a vertical with it batten, generally use glue or nail to fix.Nail implements the comparison difficulty, and a kind of is to utilize nail to pass wooden plane parent and batten joins, and this just needs nail to have enough length; Also having a kind of is that the inclination nail follows closely into that batten is connected with wooden plane parent then, and such connection is not firm.Use glue to paste, then more insecure, easier dropping.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of clamping bolt head, and it is firm to make that wooden plane parent connects with vertical batten, and vertical batten is difficult for dropping.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of clamping bolt head, comprise wooden plane parent, with the vertical batten of wooden plane parent, the lower end of described batten is provided with the bolt head, described wooden plane parent is provided with the trapezoidal draw-in groove corresponding with the bolt head.
As preferably, be provided with at least one trapezoid boss in the described trapezoidal draw-in groove, described bolt head is provided with the buckling groove corresponding with trapezoid boss.Trapezoid boss cooperates with buckling groove, makes the bolt head open with trapezoidal draw-in groove to both sides and cooperate that it is firm to connect.
As preferably, described trapezoid boss adopts two, is symmetricly set on the center line both sides of trapezoidal draw-in groove.It is more firm to connect.
Beneficial effect:
The utility model adopts technique scheme that a kind of clamping bolt head is provided, cooperate with buckling groove by trapezoid boss, make the bolt head open with trapezoidal draw-in groove to both sides and cooperate, thereby it is firm to make that wooden plane parent connects with vertical batten, vertical batten is difficult for dropping.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a clamping view of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of clamping bolt head comprises wooden plane parent 2, the batten 1 vertical with wooden plane parent 2, and the lower end of described batten 1 is provided with bolt head 3, and described wooden plane parent 2 is provided with the trapezoidal draw-in groove 4 corresponding with bolt head 3.Be provided with at least one trapezoid boss 5 in the described trapezoidal draw-in groove 4, described bolt head 3 is provided with the buckling groove 6 corresponding with trapezoid boss 5.Described trapezoid boss 5 adopts two, is symmetricly set on the center line both sides of trapezoidal draw-in groove 4.
During practical operation, as shown in Figure 2, buckling groove 6 is aimed at trapezoid boss 5, bolt head 3 is compressed into trapezoidal draw-in groove 4, trapezoid boss 5 makes bolt head 3 open with trapezoidal draw-in groove 4 to both sides to cooperate in the process that presses down, thereby it is firm to make that wooden plane parent 2 connects with vertical batten 1, and vertical batten is difficult for dropping.
