Problems solved by technology

[0003] The present invention solves the problem that when the existing screw is broken inside the screw hole, it is difficult to remove, block the screw hole, and often cause mechanical failure, and further proposes a hollow screw that can avoid blocking the screw hole after breaking
[0005] The beneficial effects of the present invention are: the present invention can use an ordinary flat-shaped screwdriver or a Phillips screwdriver to unscrew the screw body remaining in the screw hole, which solves the problem that the traditional solid screw blocks the screw hole after being broken and cannot be cleaned, and avoids causing Major mechanical failure, while saving the material for making screws and reducing the weight of screws

specific Embodiment approach 1

[0009] Specific Embodiment 1: This embodiment is described in conjunction with FIG. 1. A hollow screw described in this embodiment that can avoid blocking the screw hole after being broken includes a screw top 1 and a screw body 2. A cavity is provided in the screw body 2 along the axial direction. 3. The upper end surface of the screw body 2 is fixedly connected with the lower surface of the screw top l.

specific Embodiment approach 2

[0010] Specific implementation mode two: combination figure 2 To describe this embodiment, the cross section of the cavity 3 of a hollow screw that can avoid blocking the screw hole after being broken in this embodiment is rectangular.

[0011] The beneficial effect of this embodiment is: the cross section of the cavity 3 is rectangular, when the screw body 2 is broken in the screw hole, the broken screw body 2 remaining in the screw hole can be unscrewed by a straight screwdriver.

[0012] Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0013] Specific implementation mode three: combination image 3 To illustrate this embodiment, the cross section of the cavity 3 of a hollow screw that can avoid blocking the screw hole after being broken in this embodiment is cross-shaped.

[0014] The technical effect of this embodiment is: the cross section of the cavity 3 is cross-shaped, and when the screw body 2 is broken in the screw hole, the broken screw body 2 remaining in the screw hole can be removed by a Phillips screwdriver or a straight screwdriver. screw out.

[0015] Other components and connections are the same as those in the first embodiment.

[0016] Working principle: When the present invention is broken in the screw hole, the cavity 3 in the screw body 2 is exposed, and the screw body 2 remaining in the screw hole can be snapped into the cavity 3 by a straight screwdriver or a cross-shaped screwdriver. screw out.

Abstract

The invention relates to a cored screw capable of preventing a screw hole being blocked after being broken and aims at solving the problems that when an existing screw is broken in a screw hole, the screw is difficult to remove, the screw hole is blocked, and a mechanical failure is caused frequently. The cored screw comprises a screw top and a screw main body, a cavity is formed in the screw main body in the axis direction, and the upper end face of the screw main body and the lower surface of the screw top are fixedly connected into a whole.

Description

technical field [0001] The invention relates to a screw which can avoid blocking the screw hole after being broken, in particular to a hollow screw which can avoid blocking the screw hole after being broken. Background technique [0002] At present, most of the screws are made of solid. When solid screws are screwed into the screw holes, they often break due to improper force. The broken screws are left in the screw holes, which are difficult to remove and block the screw holes. When the screw holes are bonded to the machinery, they cannot be disassembled, often causing major mechanical failures. Contents of the invention [0003] The present invention solves the problem that when the existing screw is broken inside the screw hole, it is difficult to remove, block the screw hole, and often cause mechanical failure, and further proposes a hollow screw that can avoid blocking the screw hole after being broken. [0004] The technical solution adopted by the present invention...
