Detailed Description

The utility model provides a protective guard of a bridge-cut-off casement window, which is used for making the purposes, technical schemes and effects of the utility model clearer and more definite, and is further described in detail below by referring to the accompanying drawings and examples. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a guard rail of a bridge-cut-off casement window, including a square guard rail main body 1, a lock 2 disposed on one of the vertical side rods 11 of the guard rail main body 1, wherein the bottom and top of the guard rail main body 1 are connected with a window frame 51 through hinges 52, the lock 2 includes a cover plate 21 disposed on the inner side surface of the vertical side rod 11, a switch key 22, a locking screw 23, a slider 24 disposed on the outer side surface of the vertical side rod 11, and a clamping protrusion 25 disposed on the slider 24, wherein a vertically extending limit groove 221 is disposed on the cover plate 21, the switch key 22 is disposed in the limit groove 221 in a vertically movable manner, the head of the locking screw 23 penetrates through the cover plate 21, the slider 24 is fixedly connected with the switch key 22, a stop block 3 matched with the clamping protrusion 25 is disposed on the window frame 51, a polygonal groove 231 is disposed on the top surface of the head of the locking screw 23, a round protrusion 232 is disposed in the center of the polygonal groove 231, and a lock hole matched with the locking screw 23 is disposed on the slider 24.

Under daily use state, guardrail main part 1 is the closed state, and the protection main part is located window frame 51 promptly, blocks personnel to get into bridge cut-off flat-open window, then the user moves down through pushing on-off key 22, makes the bayonet protrusion 25 card on the slider 24 go into in the bayonet socket 31 of stop block 3 to fix guardrail main part 1's position. When the guardrail main body 1 is to be further locked to improve the protection performance, certain specific personnel (such as children and thieves) are prevented from pushing the switch key 22 to open the guardrail main body 1, at the moment, a special wrench is required to be used for screwing the locking screw 23, the locking screw 23 is matched with the lock hole to lock the position of the sliding block 24, the switch key 22 cannot be pushed to move, and therefore the position of the guardrail main body 1 is locked, and the guardrail main body 1 cannot be opened at will.

Conversely, when the window and the guard rail are to be opened to allow ventilation and a greater view and light to enter the room or to allow cleaning to be performed outside the window, it is necessary to screw the locking screw 23 with a special wrench to loosen the engagement of the locking screw 23 with the slider 24 and then push the switch key 22 upward so that the click protrusion 25 is withdrawn from the bayonet 31 of the stopper 3, thereby opening the guard rail.

Compared with the prior art, the guard rail of the bridge-cut-off casement window can be movably opened or closed, after the clamping protrusions 25 on the sliding block 24 are clamped into the bayonets 31 of the stop blocks 3, the sliding block 24 can be locked by screwing the locking screws 23 through special wrenches to be matched with locking holes on the sliding block 24, and a specific person is prevented from pushing the switch key 22 to open the guard rail main body 1. The guard rail of each broken bridge casement window is locked by adopting the same locking screw 23, and a user can open all guard rails of the broken bridge casement window only by configuring a special wrench, so that the operation is convenient and the manufacture is convenient; in addition, since the head of the locking screw 23 has a special shape, if the locking screw is screwed without the assistance of a special wrench, the unlocking difficulty is high, and the anti-theft safety is good.

It should be noted that, in one embodiment, the polygonal groove 231 is a regular hexagonal groove. Because the regular hexagonal groove is provided with the round protrusion 232, under the limitation of the round protrusion 232, the common hexagonal wrench cannot be matched with the regular hexagonal groove, namely, the common hexagonal wrench cannot screw the locking screw 23, so that the anti-theft safety is ensured. When the special spanner is designed and manufactured, the shape of the special spanner is matched with the regular hexagonal groove, a round groove matched with the round protrusion 232 is formed in the end face of the special spanner, and the special spanner can be matched with the head of the locking screw.

Specifically, the outer side surface of the vertical side rod 11 is provided with a guide groove 16 slidably connected with the sliding block 24, and the guide groove 16 extends vertically.

Further, the locking protrusion 25 includes a hollow column 251 and flanges 252 disposed at two ends of the hollow column 251, the mounting screw passes through the hollow column 251 of the locking protrusion 25 to fix the screw on the slider 24, the stop block 3 is H-shaped, and the stop block 3 is provided with a bayonet 31 matched with the locking protrusion 25.

Preferably, the sliding block 24 is fixedly connected with the switch key 22 through a connecting screw, and the vertical side rod 11 is provided with a long hole for the connecting screw to pass through, and the long hole extends vertically to play a role in avoiding. By means of the arrangement, the sliding block 24 is detachably connected with the switch key 22, and replacement and matching can be facilitated if the sliding block 24 and the switch key 22 are aged and damaged. The long hole refers to a non-round hole, and can be specifically a rectangular hole, a kidney-shaped hole, a round-corner rectangular hole and the like.

Preferably, the cover plate 21 is in snap connection with the vertical side rod 11, so that the cover plate 21 is convenient to install and fix, attractive and durable, and the problems of rust and attractive appearance caused by screw fixation are solved.

Specifically, the guardrail main body 1 comprises a frame formed by two transverse side rods 12 and two vertical side rods 11, and a plurality of transverse rods 13 fixed in the frame, wherein the transverse rods 13 are distributed at equal intervals. Because the frame adopts the design that the horizontal side rod 12, the vertical side rod 11 and the horizontal rail rod 13 enclose, the guardrail main body 1 is relatively open in vision and cannot block too much light rays and visual fields. The design can keep indoor transparent feeling, and simultaneously, a user can enjoy better outdoor landscapes.

Further, an operation window 15 is arranged in the frame and is located beside the lock 2, and the operation window 15 is surrounded by two rail rods 13, a vertical side rod 11 and a vertical rail 14. This design makes the user can be very convenient through the operation window 15 operation tool to lock 2 open or close the guardrail, realizes opening and closing of guardrail to satisfy ventilation, business turn over window outer etc. demand.
