Abstract

The overall detachable window guardrail is equipped with a spring pin connected to the spring. The spring pin is inserted into the corresponding socket on the window frame under the force of the spring. The spring pin is fixed with a button. When the button is manually toggled, The button drives the spring bolt to withdraw from the socket on the window frame; the guardrail is also equipped with a lock and a chain bolt linked with the lock. The chain bolt is inserted into the corresponding socket on the window frame, and the chain bolt and the lock are driven by the key. The rotating lock core shaft is linked, when the lock core shaft rotates towards the unlocking direction, the lock core shaft drives the interlocking bolt to withdraw from the socket on the window frame; the entire guardrail is fixed on the window frame by the spring bolt and the interlocking bolt superior. The advantage of the present invention is that as long as the spring latch and the chain latch are pulled out from the socket of the window frame, the whole guardrail can be removed, which greatly facilitates various tasks such as cleaning the glass, and is convenient for people to use in emergency situations. Fast escape, improving the safety of the fence.

Description

Integral detachable window guardrail

technical field

The present invention relates to window guards mounted on windows.

Background technique

At present, there is a movable window guardrail, which is fixed with a rotating shaft inserted into the window frame, and the whole guardrail can rotate around the rotating shaft and open like a window sash. However, the existing guardrail cannot be disassembled from the window frame as a whole, and it still cannot meet the requirements of use in some occasions. For example, in some emergency situations, the guardrail may not be opened because of obstacles in the room to a sufficiently large angle for rapid escape.

Contents of the invention

The purpose of the present invention is to provide an integral detachable window protection rail.

For this reason, the integral detachable window guard rail of the present invention, the spring latch that is connected with spring is installed on the guard rail, and the spring latch is inserted in the corresponding jack on the window frame under the action of spring force, and the spring latch A button is fixed, and when the button is manually toggled, the button drives the spring bolt to withdraw from the socket on the window frame; the guardrail is also equipped with a lock and a chain bolt linked with the lock, and the chain bolt and the lock are rotated by the key. The lock core shaft is linked, when the lock core shaft rotates towards the direction of closing the lock, the lock core shaft drives the chain bolt to be inserted into the corresponding socket on the window frame, when the lock core shaft rotates towards the unlocking direction, the lock core shaft drives the chain bolt Exit from the jack on the window frame; the whole guardrail is fixed on the window frame by means of the spring latch and the interlocking latch.

The advantage of the present invention is that as long as the spring latch and the chain latch are pulled out from the socket of the window frame, the whole guardrail can be removed from the window frame, which greatly facilitates various tasks such as cleaning glass, and is convenient for people Quickly escape in emergency situations, improving the safety of the fence.

Figure 3 and Figure 4 are examples of two different layouts of spring latches and chain latches on the guardrail (the lockset is omitted in the figure).

detailed description

Referring to Fig. 1, a window guardrail 1 is welded by a metal pipe. Spring latches 2 are installed near the upper and lower corners of the same side of the guardrail 1 respectively. Spring latch 2 is connected with spring 3, and spring 3 one end withstands on guardrail 1, and the other end withstands on spring latch 2, and spring latch 2 is inserted in the corresponding jack on the window frame 4 under the effect of spring 3. Spring latch 2 is fixed with button 5, as long as button 5 is toggled by hand, spring latch 2 can be withdrawn from the jack on the window frame 4. The button 5 can be a projection integrally formed with the spring pin 2 . Spring pin 2 and spring 3 both can be installed in the metal tube of guardrail 1, also can be installed in an independent shell, and spring pin 2 expands and contracts from this shell, and this shell and guardrail 1 are fixed as a whole.

A lock 6 and two interlocking bolts 7 linked with the lock 6 are also installed on the guardrail 1 . Interlocking bolt 7 is inserted in the corresponding jack on the window frame 4. Referring to Fig. 1 and Fig. 2 at the same time, the lock core shaft 8 of the lockset 6 is fixed with a lever 9, and a connecting rod 10 is respectively connected between the two ends of the lever 9 and the two interlock pins 7, so that the two interlock pins 7 and the lock core shaft 8 linkage. When rotating the lock core shaft 8 with the key towards the direction of closing the lock, the lock core shaft 8 drives the two interlocking bolts 7 through the lever 9 and the connecting rod 10 to be inserted into the jack of the window frame simultaneously; During axle 8, lock core shaft 8 drives two interlocking bolts 7 to withdraw from the jack of window frame simultaneously by lever 9, connecting rod 10. Chain bolt 7 and connecting rod 9 can be concealedly installed in the metal pipe of guardrail 1, and chain bolt 7 can stretch in the metal pipe of guardrail 1.

The connecting rod 10 in Fig. 2 can also be replaced by a chain. When the lock core shaft 8 is turned towards the unlocking direction with the key, the chain is used to pull the two interlocking pins 7 at the same time, so that the two interlocking pins 7 are simultaneously withdrawn from the socket of the window frame. . If replace connecting rod 10 among Fig. 2 with chain, then need to set up back-moving spring for two chain bolts 7, when rotating lock core shaft 8 toward closing lock direction with key, rely on the elastic force of back-moving spring to drive two chain bolts 7 simultaneously Insert into the socket of the window frame.

Whole guardrail 1 relies on spring latch 2 and chain latch 7 to be fixed on the window frame 4. As long as the spring latch 2 and the interlocking latch 7 are extracted from the jack of the window frame 4, the whole guardrail 1 can be removed from the window frame 4

The layout of the spring latch 2 and the interlocking latch 7 on the guardrail 1 can also adopt the example shown in Fig. 3 and Fig. 4 . Number 2 in Fig. 3 and Fig. 4 represents spring latch, and number 7 represents interlocking latch.
