[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Please refer to the attached Figure 1 -Attached Figure 4 A theft-proof plastic-steel door and window comprises a frame 1, wherein a plurality of longitudinal rods 2 are arranged inside the frame 1, a plurality of fixing grooves 3 are arranged on one side of the longitudinal rod 2, a locking structure is arranged inside the frame 1, the locking structure comprises a connecting groove 201 arranged on one side of the longitudinal rod 2, the connecting groove 201 is communicated with the fixing groove 3, a fixing strip 202 is inserted inside the connecting groove 201, locking blocks 203 are fixed at both ends of the fixing strip 202, a plurality of mounting grooves 204 are arranged on both sides of the inner wall of the frame 1, a clamping groove 205 is arranged inside the mounting groove 204, the locking block 203 and the mounting groove 204 are slidably inserted, a locking shaft 206 is rotatably arranged inside the locking block 203, a plug-in hole 207 is arranged on one side of the locking shaft 206, a locking piece 208 is slidably inserted inside the plug-in hole 207, a spring 209 is fixed between the locking piece 208 and the inner wall of the locking block 203, and a clamping shaft 210 is fixed on the outer circular wall surface of the locking shaft 206.
[0024] In the embodiment, the card-joining shaft 210 and the card-joining groove 205 are slidably inserted, a plectrum 211 is slidably inserted on one side of the insertion hole 207, a plurality of fixed grooves 3 are slidably inserted with a cross bar 4, and both ends of the longitudinal bar 2 are slidably inserted with the mounting groove 204. Through the setting of the locking structure, the longitudinal bar 2 is preliminarily installed inside the frame 1 through the mounting groove 204, and then the cross bar 4 is preliminarily installed through the fixing groove 3, and then the locking block 203 is pushed into the mounting groove 204, and at the same time the fixing strip 202 enters the connecting groove 201, so that the locking block 203 abuts against the longitudinal bar 2, and the fixing strip 202 abuts against the cross bar 4, and then the plectrum 211 is rotated so that the lock shaft 206 is brought into engagement with the locking shaft 206. The movable card shaft 210 enters the card groove 205. At this time, the locking piece 208 enters the plug-in hole 207 under the action of the spring 209 to limit the lock shaft 206. Finally, the paddle 211 is pulled out and placed in a safe position indoors to lock the installed cross bar 4 and longitudinal bar 2. When the cross bar 4 and the longitudinal bar 2 are disassembled and repaired, the paddle 211 is inserted and pressed so that the paddle 211 pushes the locking piece 208 out of the plug-in hole 207. The paddle 211 is then rotated to make the card shaft 210 leave the card groove 205, and the locking block 203 and the fixing strip 202 are pulled out. The operation is simple and convenient, and it is not easy for others to disassemble the cross bar 4 and the longitudinal bar 2 from the outside, thereby improving the anti-theft effect of doors and windows and facilitating use.
[0025] In the embodiment, a plurality of longitudinal bars 2 are evenly distributed along the height direction of the frame 1, a plurality of transverse bars 4 are evenly distributed along the length direction of the frame 1, and the longitudinal bars 2 and the transverse bars 4 are cross-arranged. The cross-arrangement of the plurality of longitudinal bars 2 and the transverse bars 4 improves the supporting effect on the interior of the frame 1, prevents the outer periphery of the frame 1 from being hit and dented, and further improves the anti-theft effect of doors and windows.
[0026] In the embodiment, a limiting plate 301 is fixed on one side of the locking piece 208, and a movable groove 302 is provided on the inner top surface of the locking block 203. The limiting plate 301 and the movable groove 302 are slidably arranged. The limiting plate 301 is slidably arranged in the movable groove 302 to prevent the locking piece 208 from rotating when it moves forward and backward under the action of the spring 209, thereby improving the locking effect.
[0027] In the embodiment, fixing plates 401 are fixed to the four sides of the frame 1, and fixing holes 402 are opened on one side of the fixing plates 401. When installing the frame 1, the staff can use expansion screws to fix the frame 1 through the fixing holes 402 and the fixing plates 401.
[0028] In the embodiment, a protective strip 5 is fixed to the inner bottom surface of the frame 1, and one side of the protective strip 5 abuts against the outer circular wall surface of the cross bar 4. The protective strip 5 can prevent the bottom end of the cross bar 4 from bending when impacted by the outside.
[0029] Working principle: During use, the staff will preliminarily install the longitudinal rod 2 inside the frame 1 through the installation groove 204, and then preliminarily install the cross bar 4 through the fixing groove 3, and then push the locking block 203 into the installation groove 204, and at the same time the fixing strip 202 enters the connecting groove 201, so that the locking block 203 abuts against the longitudinal rod 2, and the fixing strip 202 abuts against the cross bar 4, and then rotate the paddle 211 so that the lock shaft 206 drives the clamping shaft 210 to enter the clamping groove 205. At this time, the locking piece 208 enters the plug hole 207 under the action of the spring 209 to limit the lock shaft 206. Finally, pull out the paddle 211 and place it in a safe position indoors to lock the installed cross bar 4 and longitudinal rod 2. When disassembling and repairing, insert the paddle 211 and press it, so that the paddle 211 pushes the locking piece 208 out of the insertion hole 207, and then rotate the paddle 211 to make the clamping shaft 210 leave the clamping groove 205, and pull out the locking block 203 and the fixing strip 202. The operation is simple and convenient, and it is not easy for others to disassemble the cross bar 4 and the longitudinal bar 2 from the outside. The limit plate 301 is slidably arranged with the movable groove 302, and the limit plate 301 is slidably arranged in the movable groove 302 to prevent the locking piece 208 from rotating when it moves back and forth under the action of the spring 209. When installing the frame 1, the staff can use the expansion screws to fix the frame 1 through the fixing hole 402 and the fixing plate 401. The protective strip 5 can prevent the bottom end of the cross bar 4 from bending when it is hit by the outside.
[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
