Description

Anti-tamper door lock panel

technical field

The utility model belongs to a door lock, in particular to an anti-disassembly door lock panel.

Background technique

Door locks, especially mortise door locks, are equipped with inner and outer panels inside and outside the door. The installation structure of this panel is shown in Figure 1. Screws 4 whose height does not exceed the thickness of the panel are welded on the back of the outer panel 7. The screw 4 is covered with a connecting screw 6, and the position corresponding to the screw 4 is provided on the inner panel 5. Screw hole, inner and outer panels 5,7 are installed on the door leaf 1, pass and be tightened on the spiral tube 6 inner and outer panels 5,7 and door leaf 1 are fixed together with screw 4 from the screw hole of inner panel 5. The door lock panel of this structure is easy to be disassembled by the thief with tools. When committing a crime, only the outer panel needs to be knocked out of shape, and the jaws 201 (referring to Fig. 1 and Fig. 2) of the thin-nose pliers 2 are inserted into the outer panel 7 and the door leaf 1, the outer panel can be disassembled by clamping the screw tube 6 and unscrewing to achieve the purpose of destroying the lock cylinder to unlock and burglary.

Utility model content

The purpose of the utility model is to provide a door lock panel which is difficult to be disassembled.

Realize the technical scheme that the utility model object adopts as follows:

The anti-disassembly door lock panel provided by the utility model includes inner and outer panels, screws are fixed on the back of the outer panel, screw holes corresponding to the screws on the outer panel are provided on the inner panel, and screw connections with the outer panel are also included. The spiral tube; the screw includes a fixing part whose length exceeds the outer panel and a threaded connecting part, and the diameter of the screw connecting part is smaller than the diameter of its fixing part.

The beneficial effects of the utility model:

After the utility model adopts the above-mentioned structure, the connecting part of the screw is located in the door leaf, and the spiral tube is sleeved on the connecting part of the screw. part, the coil cannot be clamped, so the purpose of breaking the lock cylinder, unlocking and burglary cannot be achieved by unscrewing the coil and disassembling the outer panel.

Further illustrate the technical scheme of the utility model below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is the schematic diagram that dismantles existing house door lock with thin-nose pliers.

Fig. 2 is a view along the direction A of Fig. 1 .

Fig. 3 is a schematic structural view of the utility model.

Detailed ways

See Fig. 3, the anti-disassembly door lock panel that the utility model provides, comprises inner and outer panel 5,7, and the back side of outer panel 7 is fixed with screw 4, is provided with on the inner panel 5 corresponding to the screw 4 on the outer panel 7. The screw hole also includes the screw tube 6 connected to the screw 4 of the outer panel 7; smaller than the diameter of its fixed portion 401.

As can be seen from Figure 3, after the door lock is installed, the screw 3 passes through the screw hole on the inner panel 5, and is connected to the screw 4 through the spiral tube 6, and the inner and outer panels 5, 7 are fixed on the door leaf 1. When the screw tube 6 is connected to the connecting part 402 of the screw 4, when the jaws 201 of the thin-nose pliers 2 are inserted into the gap between the outer panel 7 and the door leaf 1, the fixed part 401 of the screw 4 can only be clamped, but not As far as the screw tube 6 is concerned, it is impossible to unscrew the screw tube 6 and disassemble the outer panel 7 to achieve the purpose of destroying the lock cylinder to unlock and burglary.

Claims (1)

1. an Anti-dismantling door lock panel, comprise inside and outside panel, and the back side of outer panels is fixed with screw, and wainscot is provided with the screw corresponding with screw on outer panels, also comprises the screwed pipe that is connected with the screw of outer panels; It is characterized in that described screw comprises that length exceeds the standing part of outer panels and the coupling part of establishing screw thread, the diameter that described screw connection portion is divided is less than the diameter of its standing part.
