Background
In order to avoid climbing through the drain pipe and prevent burglary, the existing method is to install the anti-theft plate with the anti-theft thorn on the drain pipe, but the anti-theft thorn on the common anti-theft plate can not be adjusted, and the influence on the normal construction of the outer wall can be caused.
The traditional Chinese patent with the application number of 201811010475.3 and the name of 'a PVC drain pipe anti-theft structure' is provided with an anti-climbing plate fixed on the outer side of a drain pipe, and a movable anti-theft plate arranged on the inner side of the anti-climbing plate, and the anti-theft prick of the anti-theft plate is controlled to stretch in the anti-climbing hole by utilizing the transverse movement of a pulling plate so as to prevent theft or facilitate maintenance. However, it has the following problems:
1. the pulling plate is loosened, the anti-theft thorn retracts to avoid influencing construction, the pulling plate is pulled, the anti-theft thorn extends out of the anti-climbing hole to prevent theft, and therefore the user can adjust back and forth between the two states with high probability.
2. Only the four corners of the anti-theft plate can be reinforced by the matching of the slide bars and the slide holes, and the anti-theft plate is not provided with anti-theft thorns at the four corners but is fully paved with the anti-theft thorns, so that all the anti-theft thorns cannot be reinforced, and the structure is very complex if the slide bars are arranged at multiple positions.
3. In order to move the pulling plate transversely, the anti-creeping hole is required to be larger than the transverse width of the anti-theft thorn, so that the whole structure is loose and the stability is poor.
4. When the anti-theft thorn is hidden in the anti-creep hole, the locking plate and the pulling plate still can protrude out of the outer side of the anti-creep plate and still can influence the outer wall construction.

and can move the supporting plate 5 horizontally to the left, make the supporting bar 52 move on the left slot wall of the supporting slot 34, and when the penetrating rod 6 moves to the right end of the rear perforation 51, the front side of the supporting bar 52 is supported on the rear side of the anti-theft plate 3, and the rear side of the supporting plate 5 and the front side of the anti-theft plate 3 are respectively supported against the back plate 41 and the anti-climbing plate 2, and the anti-theft thorn 31 penetrates out from the thorn outlet hole 21, and at this moment, the main lock ring 53 and the auxiliary lock ring 44 are drawn together and can pass through the padlock 7 to be fixed.
Further, the anti-theft plate 3 and the
The anti-theft device has only two states, the support plate 5 can be horizontally moved to the right, the penetrating rod 6 is positioned at the left end of the rear penetrating hole 51, the front side surface of the anti-theft plate 3 and the rear side surface of the anti-climbing plate 2 are arranged in parallel at intervals, the front end of the anti-theft thorn 31 is positioned in the thorn outlet hole 21 and blocks the thorn outlet hole 21, and the influence on the construction and maintenance work of an outer wall can be avoided; the supporting plate 5 can also be horizontally moved to the left, so that the penetrating rod 6 is moved to the right end of the rear penetrating hole 51, the anti-theft pin 31 penetrates out of the pin outlet hole 21, and the penetrating anti-theft pin 31 is used for preventing theft, so that the anti-theft device is adjustable only in the two states, and is convenient for users to use; in the anti-theft device, when the through rod 6 moves to the right end of the rear through hole 51, the front side surface of the supporting bar 52 is abutted against the rear side surface of the anti-theft plate 3, and the rear side surface of the supporting plate 5 and the front side surface of the anti-theft plate 3 are respectively abutted against the back plate 41 and the anti-climbing plate 2, so that the anti-theft spines 31 at all positions of the anti-theft plate 3 can be supported by the supporting plate 5, the stability of the anti-theft spines 31 at all positions is improved, and the anti-theft spines 31 are prevented from being extruded violen; the anti-theft plate 3 in the device can only move in the direction vertical to the anti-climbing plate 2, so that the anti-theft pin 31 and the pin outlet hole 21 are matched more compactly, and the phenomenon that the whole structure is loosened due to the fact that the pin outlet hole 21 is too large is avoided; and this device can utilize the regulation of taking the magnetic path to adsorb on bounding wall 42 to drive backup pad 5 and remove, take off at ordinary times and adjust the handle, can avoid being adjusted at will, also can remove main catch 53, thereby drive backup pad 5 and remove, make main catch 53 and vice catch 44 draw close, and can pass padlock 7 and fix, consequently the regulation mode is more, can select according to particular case, and can avoid influencing the normal construction operation of outer wall completely.
A manufacturing method of an anti-theft device of a PVC drain pipe comprises the following steps:
step one, bending an anti-theft plate 3 and a
bending a steel plate, welding the edge to form a connecting
and step three, placing the anti-theft plate 3 and the
