Abstract

A theft-proof guardrail connector with a tension spring and an electronic switch includes a connector, a tension spring, and an electronic switch. The connector comprises a rectangular base plate with a hinge at the front end, side panels extending upward from the middle of the base plate, a front plate above the side panels, mounting holes, and a switch box within the front plate. The switch box houses an electronic switch and a tension spring. The hinge is fixed to the guardrail base frame, and the tension spring is fixed to the guardrail frame. The connector is installed on the left and right window sills of a window, with the guardrail parallel to the window. When the guardrail is subjected to external forces such as climbing, pushing, pulling, or stepping on by a thief, the guardrail rotates a certain angle, triggering an alarm signal from the elastic electronic switch. The connected alarm host issues an alarm message, and the connector can also form an Internet of Things (IoT) through a communication network, enabling remote control.

Description

An anti-theft guardrail connector with tension spring and electronic switch

technical field

The invention relates to the field of mechanical structures, in particular to an anti-theft guardrail connector with a tension spring and an electronic switch.

Background technique

The balconies and windows of existing buildings basically use fence-type anti-theft windows as shrouded protection and anti-theft. As the connecting parts for installation, they all play a fixed role and do not move. Although they can play a part of anti-theft function, there are also many disadvantages. : the first, the connecting piece and the protective fence are not strong, and the thief is easy to cut off, pull off, etc. in a few minutes, and then get in to steal; tools, causing safety threats or property loss or even life injury to upper-level residents, thus causing conflicts among neighbors and affecting social harmony; If the window is not effectively protected, it will easily become the target of thieves. Therefore, many multi-storey houses have installed guardrails/anti-theft windows from the first floor to the top floor, which gives people a sense of depression. Everyone lives in an iron cage. Affect the quality of life; the 4th, the fence type anti-theft window of this fixed connector also influences the attractive in appearance of building, especially tourist city, the building windows on both sides of the street are all covered by iron fence, have had a strong impact on city appearance, return to Tourists leave a bad impression of law and order, which affects the mood of tourists; fifth, if a fire occurs in a building and other accidents that endanger the lives of many people and the property safety of the entire building, it is necessary to evacuate and rescue the people in the building from other passages, because The protective device of the fixed connection firmly seals the entire window and balcony, and the people in the building cannot evacuate or escape from the window or balcony, and the rescuers outside cannot enter to rescue people and disaster relief, so there is a major safety hazard ; The 6th, because guardrail body is immovable after fixed connector is installed, so alarm switch can not be installed and the thieves are warned in time.

Contents of the invention

In order to solve the above technical problems, the object of the present invention is to provide an anti-theft guardrail connector with a tension spring and an electronic switch that can rotate at a certain angle under the pull of an external force. The entry position of the window is enough, so the height of the guardrail can be 20-50cm to have a blocking effect. In case of external invasion such as climbing or hanging into the window and stealing, the guardrail connected by the connecting piece will be inclined by force, and the connecting piece The electronic switch on the switch immediately turns on the alarm, and the alarm equipment connected to the electronic switch can automatically make on-site sound and light alarms and make phone calls to alarm and record video, which can effectively warn/stop the theft and provide information for catching the thief immediately; The guardrail can be rotated, so it can prevent the alarm without covering the window. It is convenient to enter and exit the window in an emergency without endangering the existing building. The window can be used as a safe evacuation channel and rescue and disaster relief. Disadvantages of connector-mounted guards.

The technical scheme that the present invention adopts is as follows:

There are side plates, the top of the side plates is provided with a front plate, the bottom plate is also provided with mounting holes, the front plate is provided with a switch box, the switch box is provided with an electronic switch and a tension spring, and the hinge is fixed On the bottom frame of the guardrail, the extension spring is fixed on the frame of the guardrail.

Further, installation holes are distributed from front to back in the middle of the bottom plate, and indentations are provided between the several installation holes at the rear end of the bottom plate.

Further, holes are distributed from top to bottom in the middle of the side plate, a horizontal front plate is arranged on the top of the side plate, and holes are distributed in the middle of the front plate from top to bottom, and the switch box is fixed on the front of the front plate through the holes. .

Further, the inside of the switch box is provided with an electronic switch and a tension spring, the electronic switch is an elastic key-type normally open touch electronic switch, and the switch is connected to an alarm device; the rear end of the tension spring is fixed in the switch box , the front end is provided with a hook, and the hook is hung on the guardrail frame or the inner net of the guardrail arranged in front of it.

Further, the alarm device is an on-site alarm or a wireless transmitter, and the wireless transmitter is connected to the wireless alarm.

The invention also discloses a method for manufacturing an anti-theft guardrail connector with a tension spring and an electronic switch, including the following processes and steps:

1) An anti-theft guardrail connector with a tension spring and an electronic switch, including a connector, a tension spring and an electronic switch. The connector is made of sheet metal stamping and includes a rectangular bottom plate whose middle side is bent upwards to form The side plate, the upper part of the side plate is bent transversely to form the front plate, there are installation holes distributed from front to back in the middle of the bottom plate, there are indentations between the several installation holes at the end of the bottom plate, and there are several stamping holes on the side plate and the front plate hole;

2) A hinge is set at the front end of the bottom plate, and there is a stamped guardrail connection hole on the hinge;

3) A switch box is set on the front plate, and the rear part of the switch box is fixed through the holes on the front plate with screws;

4) An electronic switch and an extension spring are arranged in the switch box. The electronic switch is arranged on the upper part of the extension spring. The electronic switch selects an elastic key-type normally open touch electronic switch, and the switch is connected to an alarm device; one end of the extension spring is fixed in the switch box , the other end is provided with a hook extending out of the switch box to a certain length;

5) Installation: Two anti-theft guardrail connectors with tension springs and electronic switches obtained through the above process and steps, respectively use screws to fix the hinges on the two ends of the guardrail bottom frame, and fix the screws on the window sill through the mounting holes of the bottom plate On, the above-mentioned extension spring hook is hung on the guardrail frame or the inner net of the guardrail arranged in front of it, and the switch is connected to an on-site alarm or a wireless transmitter, and the wireless transmitter is connected to a wireless alarm;

6) Use: The installed anti-theft guardrail with tension spring and electronic switch stands on the window to prevent thieves from entering the window.
