Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a telescopic door guardrail. Background Art

[0002] The child guardrail mainly protects children and limits the range of children's activities to a safe area. The current child guardrail is mainly used beside the bed to prevent children from falling from the bed, or to enclose a certain range on the ground for children to move around in. However, due to the limitation of the environmental space, the guardrail space enclosed by the ground cannot be very large. Only a partial space of a room can be fenced into an activity space, which leads to the limitation of the children's activity space and affects the children's activity range. Therefore, in order to expand the children's activity range, the current manufacturers have designed some guardrails that can use the entire room as a children's activity space, and the guardrail is fixed on the door frame of the room to isolate the room from the outside world and prevent children from going out of the room. However, the current guardrail must be customized according to the length between the door frames on both sides. Therefore, if you need to install the product, you must first measure the door frame distance, and then customize it to the manufacturer, resulting in a relatively high purchase cost. The manufacturer cannot mass produce, and once the customization is completed, the size cannot be changed at will. Therefore, it can only be installed one-to-one, and it cannot be suitable for any door frame size, thereby reducing the utilization rate, and the width of the guardrail is immutable, which makes packaging difficult. Utility Model Content

[0003] The utility model aims at the above-mentioned current guardrail that must be customized according to the length between the door frames on both sides. Therefore, when installing the product, the distance between the door frames must be measured first, and then customization is carried out from the manufacturer, resulting in a relatively high purchase cost. The manufacturer cannot produce in batches, and once the customization is completed, the size cannot be changed at will. Therefore, it can only be installed one-to-one and cannot be suitable for any door frame size, thereby reducing the utilization rate.

A connecting head B7-2 is connected to a pin shaft on the fixed block C7-1, and the connecting head B7-2 is fixedly mounted on the lower end of one side of the main fence 2.

[0047] In this embodiment, a fixing block C7-1 is connected to the lower end of the vertical rod A1, and the fixing block C7-1 is pin-connected to the connecting head B7-2 to achieve connection and rotation of the main fence frame 2.

[0048] Furthermore, the secondary locking connection assembly 9 includes a rectangular block 9-1, which is fixedly mounted inside the lower end of one side of the secondary fence 4, and a plug 9-2 is movably mounted inside the rectangular block 9-1. A fixed block D9-3 is fixedly mounted on the lower end of the vertical rod B3, and the end of the plug 9-2 is movably embedded in one side of the fixed block D9-3. A plug 9-4 is fixedly mounted on one side of the rectangular block 9-1, and a spring D9-5 is arranged between the plug 9-2 and the plug 9-4.

[0049] In this embodiment, the fixed block D9-3 is connected to the lower end of the vertical rod B3, the rectangular block 9-1 is fixed on one side of the lower end of the auxiliary fence 4, and is inserted into the fixed block D9-3 through the plug 9-2. The spring D9-5 is arranged between the plug 9-4 and the plug 9-2 to fix the auxiliary fence 4, and when an external force pushes the auxiliary fence 4, the plug 9-2 leaves the fixed block D9-3.

[0050] Furthermore, the lower end of the handle 8-1 is bolted to a handrail 8-10.

[0053] In this embodiment, the support plate 10 is adhered to the door frame or the wall to fix the entire structure.

[0054] It should be pointed out that, in the specific implementation process, when the main fence 2 drives the secondary fence 4 to rebound automatically, the structure between the button 8-7 and the slider 8-2 will not interfere with the insertion of the insert block 8-3 into the fixed block A8-4, but if the slider 8-2 is manually slid, the button 8-7 needs to be pressed;

[0055] This structure is easy to disassemble. After the vertical rod A1 and the vertical rod B3 are fixed to the door frame or the wall through the support plate 10, all parts except the fixing block A8-4, the fixing block B6-1, the fixing block C7-1 and the fixing block D9-3 can be disassembled, so as to facilitate use.

[0056] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
