Description

Technical Field

[0001] The utility model relates to a telescopic and adjustable door and window guardrail, belonging to the technical field of door and window guardrails. Background Art

[0002] For people's houses, in order to improve the anti-theft effect, especially for bungalows or lower floors, anti-theft windows are usually installed. The anti-theft windows currently used have an overall cage structure and a railing structure. Among them, the railing structure is more widely used because of its simpler structure and easy installation.

[0003] However, the disadvantage of the railing structure anti-theft window is that the guardrail and the frame are fixed structures. If you need to go out through the window, for example, in the event of a fire, or when you need to go out to install an air conditioner outdoor unit, it is very inconvenient; in serious cases, it will cause irreparable losses.

[0009] A further improvement of the technical solution is that notches for accommodating lifting chains are provided at both ends of the upper end surface of the guardrail in the upward direction.

[0010] A further improvement of the technical solution is that the protective cover is made of plastic material.

[0011] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0012] The utility model is a telescopic and adjustable door and window guardrail, which is installed at the window and used as an anti-theft window. The guardrail of the guardrail is installed at intervals using a hanging chain, and the guardrail is not fixedly installed but can be raised and lowered. Therefore, when it is necessary to pass through, the guardrail can be raised to open the window passage.

[0013] In the utility model, a hanging chain is provided for the guardrail, and the guardrail is installed through the hanging chain, and the spacing of the guardrail can be set on site according to different actual needs.

[0014] The utility model provides notches at both ends of the upper end surface of the guardrail in the upward direction. When the guardrail 2 is upward, the hanging chain can be retracted into the notches, and the overall appearance is not affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0021] The utility model is a telescopic and adjustable door and window guardrail, which is mainly installed at the window and plays the role of a guardrail. The position and spacing of the guardrail in the utility model can be adjusted.

[0022] like Figure 1 As shown, the guardrail comprises an outer frame 1 and a guardrail 2 slidably arranged in the outer frame 1. The outer frame 1 is a rectangular frame, and the inner sides of the connecting rods on both sides of the vertical direction have a slide groove. The guardrail 2 is provided with a plurality of guardrails 2, and the guardrail 2 can slide in the slide groove, thereby realizing the opening and closing control of the window.

[0023] The two ends of the guardrail 2 are connected by a hanging chain 3, and all the guardrails 2 are connected by the same hanging chain 3. A hanging chain 3 is set at each end of the guardrail 2. The guardrail 2 is arranged horizontally, and the height position of the guardrail 2 installed on the hanging chain 3 can be adjusted according to actual needs. The hanging chain 3 plays the role of connecting all the guardrails 2, and the hanging chain 3 generally uses a chain link type chain. Other parts that can achieve suspension connection can also be used here, and the chain link type chain is the best part to use.

[0024] In the specific installation, the two ends of the guardrail 2 are connected to the hanging chain 3 with bolts, and the position of the guardrail 2 is adjustable. For example, a chain link type chain is used, and bolts are passed through the chain links of the hanging chain 3, and then the bolts are tightened and connected with the guardrail 2.

[0025] In the specific implementation of the present utility model, it is usually necessary to set protective covers 4 at both ends of the guardrail 2. The protective cover 4 mainly plays two roles. One is to cooperate with the guardrail 2 to connect with the lifting chain 3. The other is to be installed in the slide groove of the outer frame 1 as a sliding member. As shown in the figure, when installing the protective cover 4, after using the protective cover 4 to cover the lifting chain 3, the lifting chain 3 is connected to the guardrail 2 from the outside of the protective cover 4 with bolts. When the guardrail 2 is installed in the outer frame 1, the protective cover 4 is located in the slide groove of the outer frame 1. Further, in the specific implementation, preferably, the protective cover 4 is made of plastic material.

[0026] The lowest guardrail 2 can be fixed to the outer frame 1 .

[0027] When the guardrail 2 is moved upward, the chain 3 needs to be stored. The corresponding structure is that notches 5 are set at both ends of the upper end surface of the guardrail 2 in the upward direction, so that when the guardrail 2 is moved upward, the chain 3 can be stored in the notch 5, and the overall appearance is not affected.

[0028] The utility model uses the wire control technology in the technical field to control the lifting and lowering of the guardrail 2. Specifically, fixed pulleys are arranged at both ends of the lowest guardrail 2, and a suspension rope is arranged in the slide groove of the outer frame 1. The upper end of the suspension rope is fixed to the outer frame 1, and the other end is passed downward from the bottom of the fixed pulley on the corresponding side and then extends obliquely upward toward the fixed pulley on the other side, and after passing from the top of the fixed pulley on the other side, the end is fixed to the lower part of the outer frame. The suspension ropes on both sides are set in the same way.

[0029] The utility model is installed at the window and can be used as an anti-theft window. The guardrail can be raised and lowered to open and close. When it is necessary to pass through, such as when a fire occurs and you need to escape, or when you need to go out to install an air conditioner outdoor unit, you can raise the guardrail. The guardrail is installed by a hanging chain, and the spacing of the guardrail can be set on site according to different actual needs.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
