Abstract

The utility model relates to an inverted tooth connection screw, which comprises a tooth column provided with inverted teeth, wherein the root of the tooth column is provided with a connecting part. The connecting part comprises a connecting column body, and the diameter of the head portion of the connecting column body is larger than that of the connecting column body. The connecting part comprises the connecting column body provided with an annular cut groove. The head portion of the connecting column body is conical or spherical. The connecting part comprises a nut part provided with a matched screw. A step is arranged at the position where the tooth column is connected with the connecting part and also provided with inverted teeth. The head portion of the tooth column is conical. By adopting the structure, the inverted tooth connection screw can be further connected with other parts after being knocked into a wall body and is convenient to operate. The other parts, particularly larger parts can be replaced conveniently, and the screw can be recycled after being knocked into the wall body so as to save resources.

Description

The pawl attachment screw
Technical field
The utility model relates to the link in the hardware industry, especially relates 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
The utility model technical problem to be solved provides a kind of dismounting that do not need, and connects the pawl attachment screw of heavy parts very easily.
The technological scheme that its technical problem of the utility model solution is taked is: 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 beneficial effect of the utility model is: 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 utility model;
Fig. 2 is the another kind of structural representation of the utility model.
Fig. 3 is the third structural representation of the utility model.
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 utility model 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.
Link 3 as shown in Figure 2 comprises connection cylinder 3-1, connects cylinder 3-1 and is provided with annular grooving 3-2; Fig. 1 and Fig. 2 the head that is connected cylinder (3-1) tapered or spherical.
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.
