Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to a self-locking function protective net. Background Art

[0002] Most of the protective nets in the current market adopt aluminum alloy frames. For the anti-theft nets made of aluminum alloy, because they occupy more visual space, the aesthetics is affected. Therefore, there are also invisible protective windows, usually mainly made of thin steel wires. However, due to poor strength, the appearance is easy to age, the steel wires are easy to break, and the service life is short.

[0003] To solve the above problems, there are also some products on the market that use thin protective rods instead of steel wires. Their structures are as follows: Figure 1 、 Figure 2 As shown, for example, a protective net fixing device, the protective net fixing device includes a thin protective rod 2' and a fixing plate 1'. A plurality of internally threaded circular holes for the thin protective rod 2' to pass through are provided on the fixing plate 1'. The internally threaded circular holes on the fixing plate 1' through which the thin protective rod 2' passes are screwed with nuts 3', so as to connect the thin protective rod 2' and the fixing plate 1' together. The fixing plate 1' is inserted into the guide rail 6' and fixed in the guide rail 6' by bolts 63'. When installing this structure, the thin protective rods 2' need to be placed one by one into the grooves of the guide rail 6', and then a special screw rod is used to tighten the nuts 3'. Since the screw rod needs to be specially made and the bolts are tightened manually, the operation is extremely inconvenient. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a self-locking function protective net that is convenient to install and maintain.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0007] The upper guide rail and the lower guide rail are respectively installed on the wall and located outside the window. The upper parts of the plurality of protective small frames are respectively clamped on the upper guide rail, the lower parts of the plurality of protective small frames are respectively clamped on the movable plates, the movable plates are sleeved in the lower guide rail, the fasteners pass downward through the through holes on the top surface of the lower guide rail, the middle parts of the fasteners are screwed in the screw holes on the top of the movable plates, and the lower ends of the fasteners abut against the lower parts of the protective small frames, so as to fix the protective small frames between the upper guide rail and the lower guide rail.

[0008] The protective small frame includes two protective thin rods and two cross bars; the cross bars are tubular members with a through hole extending through the entire length; the upper and lower ends of the protective thin rods are bent inward by 90°, and the bent segments at the upper and lower ends of the protective thin rods are respectively inserted into the two ends of the through hole of the cross bar, forming a rectangular member.

[0009] The protective small frame includes two protective thin rods and two cross bars; the upper and lower ends of the two protective thin rods are respectively fixed on the cross bars, forming a rectangular member.

[0010] A fixing nut is fixed at the center of the top of the movable plate, and the fixing nut forms a threaded hole at the top of the movable plate.

[0011] The cross bar is a tubular member made of aluminum alloy material.

[0012] A plurality of notches are provided on both the upper guide rail and the lower guide rail, and the plurality of notches are arranged at equal intervals to allow the protective thin rods on the protective small frame to pass through.

[0013] The protective small frame includes two protective thin rods and one cross bar; the cross bar is a tubular member with a through hole extending through the entire length; one end of the protective thin rod is bent inward by 90°, the bent segment of the protective thin rod is inserted into the through hole of the cross bar, forming a U-shaped member, and the other end of the protective thin rod has a thread and is screwed with a T-shaped nut.

[0014] After adopting the above scheme, the utility model has the following advantages:

[0015] 1. In the utility model, the movable plate is sleeved in the lower guide rail with a gap, the lower part of the protective small frame is sleeved in the movable plate, and the movable plate is pressed against the lower guide rail by a fastener. Because the fixing bolt forms a downward acting force on the movable plate, the protective thin rods on the protective small frame are straightened and fixed on the upper and lower guide rails, so as to fix the protective small frame. This installation method can realize the fixation of the protective small frame as long as the fastener is tightened, and the installation is very convenient and fast.

[0016] 2. Since the protective net will be damaged in the protective small frame after being used for a period of time, the fastener is loosened, and the protective small frame can be replaced, and the later maintenance is very convenient.

[0017] 3. Since the protective small frame of the utility model is composed of two protective thin rods and two cross bars, the cross bars are tubular members, and the bent segments at the upper and lower ends of the protective thin rods are respectively inserted into the two ends of the through hole of the cross bar, forming a rectangular member. The protective small frame can be made without welding, and the processing is very convenient.

[0018] Therefore, the utility model has the advantages of convenient installation, high installation efficiency and convenient maintenance.
