DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a building security monitoring inspection and maintenance device, comprising two support frames 1, one end of the two support frames 1 is rotatably connected together, so that the two support frames 1 can be opened and closed, each support frame 1 is installed with a plurality of pedals 2 arranged in layers, and the surface of the pedals 2 is also provided with anti-slip patterns, and the support frame 1 is preferably an aluminum alloy frame, which not only has sufficient support strength, but also has a light weight compared to other metal frames, and the pedals 2 are made of the same material as the support frame 1;

[0024] In actual use, the two support frames 1 can be opened first to form a "V" shape, and then the bottoms of the two support frames 1 are supported on the ground. Of course, in order to avoid the two support frames 1 from opening at too large an angle, such as Figure 1 and Figure 2 As shown, the middle positions of both sides of the two support frames 1 are rotatably provided with pull rods 4, and the free ends of the two pull rods 4 on the same side are rotatably connected together. When the two pull rods 4 on the same side are pulled into a straight line, the opening angle of the two support frames is at the maximum;

[0025] Secondly, two support frames 1 can be stacked together for use. At this time, the pull rod is folded at the side of the support frame 1, and the two support frames 1 can be regarded as one frame, so that the frame can be directly placed against the wall for use.

[0026] In order to increase the bottom stability of each support frame 1 and prevent the support frame 1 from tipping over during use, a support mechanism is provided at the bottom of each support frame 1, such as Figure 1 and Figure 2 As shown, support seats 7 are installed on both sides of the bottom of each support frame 1, and the support seats 7 are spaced a certain distance from the bottom of the support frame 1, so that the support seats 7 are arranged above the bottom of the support frame, and a cylindrical hole is provided in the support seat 7;

[0027] A support shaft 5 parallel to the support frame is movably provided in each support seat 7, that is, the support shaft 5 is placed in the hole, the support shaft 5 can be extended and retracted in the support seat 7, and the two ends extend outside the two ends of the support seat 7 respectively, and a support arm 6 is vertically installed on the top of each support shaft 5, the top of the support shaft 5 is connected to the end of the support arm 6, and the other end of the support arm 6 is vertically connected to a support leg 15, and the support arm 6 and the support leg 15 form an "L"-shaped structure. When in use, the support arm 6 can be held to lift or move the support leg 15 up or down, such as Figure 3 As shown in FIG. 1 , when the leg 15 moves down to the lowest position, the bottom of the leg 15 extends out of the bottom of the support frame, as shown in FIG. Figure 4 As shown, when the legs 15 are lifted to a high position, the bottom of the legs 15 is lifted above the bottom of the support frame and separated from the ground;

[0028] like Figure 3 and Figure 4 As shown, an annular support 11 is provided on both sides of each support seat 7, and the two annular supports 11 are respectively distributed at the two ends of the support seat 7, that is, the two annular supports 11 are staggered, and an adjusting screw 12 is provided on the side of the support leg 15 close to the support seat 7 and radially arranged with the support shaft 5. The adjusting screw 12 is threadedly connected to the adjusting threaded tube 13, and a certain distance is provided between the annular support 11 and the end of the adjusting threaded tube 13. In the initial state, the adjusting threaded tube 13 is completely located on the adjusting screw 12. When the adjusting threaded tube 13 is held by hand and rotated, the adjusting threaded tube 13 will extend along the adjusting screw toward the support seat.

[0029] Specifically, when the utility model is used, 1. Figure 1 and Figure 4 As shown, the legs can be stored for use, that is, when the legs 15 are lifted and turned over on the side of the support frame 1, the threaded tube 13 is adjusted to correspond to the annular support 11 located on the top of the support seat 7, and the bottom of the legs 15 is retracted into the side of the support frame 1;

[0030] 2. The legs can be opened, such as Figure 2 and Figure 3 As shown, the support area at the bottom of the support frame is enlarged. When the legs 15 are opened, they are distributed on both sides of the support frame. At this time, the legs 15 are supported on the ground. Compared with the bottom of the support frame directly resting on the ground, the support range is larger and more stable. That is, when the legs 15 are pushed down and turned to the side of the support frame 1, the threaded tube 13 is adjusted to correspond to the annular support 11 at the bottom of the support seat 7. At this time, the bottom of the lifted legs 15 extends outside the bottom of the support frame 1.

[0031] Whether the legs 15 are opened or stored, the legs 15 can be fixed, that is, the adjusting threaded tube 13 is rotated to extend it and placed in the annular support 11, and a stopper 14 is provided at one end of the adjusting threaded tube 13 away from the legs 15, and the stopper 14 is placed in the annular support 11. In this way, the legs can be firmly fixed, so that the legs will not shake during the process of carrying and transporting, and the friction between the maintenance ladder and the ground can be increased by the legs 15 against the ground.

[0032] Furthermore, the bottom of the support shaft 5 is connected to the support leg 15 via a reinforcing rod 8 , which not only strengthens the connection strength between the support leg 15 and the support shaft 5 , but also prevents the support shaft 5 from escaping from the support seat 7 .

[0033] Furthermore, two second conical heads 10 are symmetrically provided at the bottom of the two support frames 1, and a first conical head 9 is provided at the bottom of each leg 15. In this way, no matter whether the support frame is used directly or the legs are opened for use, they can be supported on the ground by the conical heads to play an anti-slip role.

[0034] In the actual maintenance process, various tools will be used, such as a multimeter, a screwdriver, a wire cutter and other tools. These tools cannot be stored during use. At this time, these tools can be placed on the cloth bag 3. The cloth bag 3 is located at the top of the support frame. The two sides of the cloth bag 3 are respectively connected to the pedals 2. When the two pull rods 4 are horizontal, the cloth bag 3 is in a downwardly bent "U" shape, so that the tools placed on the cloth bag 3 will not slide and fall.

[0035] Based on the above embodiment, further optimization can be performed by setting the support seat 7 at the inner edge of the support frame 1, so that a step structure is formed between the side where the two support seats are away from each other and the support frame 1. When the support leg 15 is flipped, the support arm 6 can be directly stacked on the support frame 1, which is convenient for positioning the support leg.
