Abstract
The invention relates to a pawl connecting bolt. The pawl connecting bolt comprises a toothed column, wherein a pawl is formed on the toothed column; a connecting piece is arranged at the root of the toothed column; the connecting piece comprises a connecting column body, wherein the diameter of the head part of the connecting column body is greater than that of the connecting column body; or the connecting piece comprises a connecting column body, wherein an annular groove is formed in the connecting column body; the head part of the connecting column body is conical or spherical; or the connecting piece comprises a nut piece, wherein a matched bolt is arranged on the nut piece; a step is formed at the position where the toothed column is connected with the connecting piece; a pawl is also formed on the step; and the head part of the toothed column is conical. After adopting the structure, the pawl connecting bolt can connect other components after being nailed into a wall body, is convenient to operate and can facilitate the replacement of other components, particularly large-scale components; and the bolt can be recycled and used after being nailed into the wall body, thereby saving resources.
Description
Technical field
The present invention relates to the link in the hardware industry, especially relate to a kind of pawl attachment screw that can conveniently fix.
Background technique
A kind of screw is arranged in the existing technology, and it comprises screw head and screw rod portion, and screw rod portion is provided with pawl; Because pawl is arranged, do not allow in the body of wall and should extract, the phenomenon that can not occur coming off voluntarily so screw squeezed into; Can the unsettled part of better protect be unlikely to drop and be damaged; But, this screw can only be when squeezing into body of wall retaining element, can not be after squeezing into body of wall retaining element; Some heavy parts is that need to get into body of wall at screw latter linked, so this kind screw is in that to connect heavy parts just inapplicable; In the needs renewal part, this kind screw must remove earlier, and then the part that is changed is squeezed within the walls, and this screw just can not have been used after pulling down again, so when changing part, will cause waste.
Summary of the invention
Technical problem to be solved by this invention provides a kind of dismounting that do not need, and connects the pawl attachment screw of heavy parts very easily.
The present invention solves the technological scheme that its technical problem takes: a kind of pawl attachment screw, comprise the tooth post, and the tooth post is provided with pawl, and the root of described tooth post is provided with link.
Connect other part for ease, a kind of scheme is: described link comprises the connection cylinder, and the diameter of the head of connection cylinder is greater than the diameter that connects cylinder; Second kind of scheme is: described link comprises the connection cylinder, connects cylinder and is provided with annular grooving.
Link plays leading role in union piece for ease, and the head of described connection cylinder is tapered or spherical.
Further other part of installation and removal for ease, the third scheme is: described link comprises nut part, and the screw that matches is installed on the nut part.
Further for the screw damage pawl that in hammering into body of wall, can not rotate, the position that described tooth post is connected with link is provided with step, also is provided with pawl on the step.
Further the tooth post hammers in the body of wall for ease, and described tooth post head is tapered.
The invention has the beneficial effects as follows: adopted after the said structure; The pawl attachment screw can connect other part again after hammering into body of wall; Easy-to-operat can be changed other part easily, and it is convenient especially to change heavy parts; Screw can recycle after hammering into body of wall, has saved resource.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is an another kind of structural representation of the present invention.
Fig. 3 is the third structural representation of the present invention.
Among the figure: 1, tooth post; 2, pawl; 3, link; 4, step; 3-1, connection cylinder; 3-2, annular grooving; 3-3, nut part; 3-4, screw; The head of 3-5, connection cylinder.
Embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
A kind of pawl attachment screw as shown in Figure 1 comprises tooth post 1, and tooth post 1 is provided with pawl 2, and the root of described tooth post 1 is provided with link 3; Link 3 comprises connection cylinder 3-1, and the diameter of the head 3-5 of connection cylinder 3-1 is greater than the diameter that connects cylinder 3-1.
The another kind of structure of link 3 as shown in Figure 3, link 3 comprises nut part 3-3, and the screw 3-4 that matches is installed on the nut part 3-3.
More attractive in appearance for screw is used, the position that described tooth post 1 is connected with link 3 is provided with step 4, for screw can not rotate on wall, also is provided with pawl on the said step 4; Described tooth post 1 head is tapered.
When in use; Screw is through pawl being installed on the body of wall tightly; First kind of scheme snaps into part in the annular grooving 3-2 through being connected cylinder 3-1 with second kind of scheme, accomplishes connecting moves, and second kind of scheme can be controlled the distance of part and back step 4; The third scheme is opened screw 3-4 and nut body 3-3, puts into part, screw 3-4 is cooperated with nut body 3-3 tighten afterwards, has so just accomplished the part fitting operation, and when tearing open, reverse operating gets final product; When in use, also can directly look for threaded part directly to connect.
