Description

Technical Field

[0001] The utility model relates to an engineering ladder with multi - angle adjustable support. Background Art

[0002] Engineering ladders are usually used in engineering construction or house decoration. They adjust the span by hinging the main ladder and the auxiliary ladder. Usually, a hinged rod is also provided between the main ladder and the auxiliary ladder to control the maximum opening range. However, when construction workers operate on it, it is inevitable that the center of gravity shifts due to construction actions. Conventional engineering ladders do not have supports on their left and right sides, resulting in the phenomenon that the engineering ladder is prone to overturning. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an engineering ladder with multi - angle adjustable support. This engineering ladder has side supports, which can support the side and can adjust the span of the support.

The main ladder and the auxiliary ladder are hinged on a connecting plate, and a hinged rod is provided between the main ladder and the auxiliary ladder. Side support mechanisms are installed on both sides of the main ladder and the auxiliary ladder. The side support mechanism includes a connecting seat, a side support foot frame rotatably connected to the connecting seat, a pair of fixing rods installed on both sides of the side support foot frame, and a track for installing the fixing rods. One end of the fixing rod is installed on the track and can move along the track, and the other end is hooked on the side support foot frame.

[0005] As a further improvement of the utility model, the side support foot frame includes an upper foot frame and a lower foot frame. The lower foot frame is provided with a fixing ring for connecting the fixing rod. The side support foot frame adjusts the length of the extended lower foot frame through threaded connection.

[0006] As a further improvement of the utility model, the fixing rod includes a main rod, a sub - rod and a hook. One end of the main rod is installed in the track and can slide along the track. The other end of the main rod is threadedly connected to the sub - rod to adjust the length of the extended sub - rod. The hook is installed at the end of the sub - rod.

[0007] As a further improvement of the utility model, a slider is provided in the track. A first connecting ring is provided on the slider, and a second connecting ring that is movably matched with the first connecting ring is provided at one end of the main rod close to the slider.

[0008] As a further improvement of the utility model, the hook is connected to the end of the sub - rod through a ball joint.

[0009] As a further improvement of the utility model, the connecting seat is fixed on the side of the connecting plate, and the end of the side support foot frame where it rotates is spherical.

[0010] Advantages of the utility model: The side support mechanisms are provided on both sides of the engineering ladder, which can provide reliable support for the whole and can be adjusted to different spans according to the environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following will further describe the present utility model in detail with reference to the embodiments given in the drawings.

[0015] Referring to Figure 1-2 as shown, an engineering ladder with multi-angle adjustable support includes a main ladder 1 and an auxiliary ladder 2. The main ladder 1 and the auxiliary ladder 2 are hinged on a connecting plate 3, and a hinge rod 4 is provided between the main ladder 1 and the auxiliary ladder 2. Side support mechanisms are installed on both sides of the main ladder 1 and the auxiliary ladder 2. The side support mechanisms can stably support the engineering ladder and prevent the phenomenon of overturning caused by excessive construction actions of construction workers. The side support mechanisms include a connecting seat 5, a side support leg frame 6 rotatably connected to the connecting seat 5, fixing rods 7 installed in pairs on both sides of the side support leg frame 6, and a track 8 for installing the fixing rods 7. The side support leg frame 6 installed on the connecting seat 5 can cooperate with the main ladder 1 and the auxiliary ladder 2 to adjust the support angle. One end of the fixing rod 7 is installed on the track 8 and can move along the track 8, and the other end is hooked on the side support leg frame 6. Installing one end of the fixing rod 7 on the track 8 can cooperate with the opening angle of the side support leg frame 6 to adjust different spans.

[0016] The side support leg 6 includes an upper support leg 61 and a lower support leg 62. A fixing ring 621 for connecting a fixing pressing rod is provided on the lower support leg 62. In this solution, the fixing rings 621 are arranged along the axial direction of the lower support leg 62. The side support leg 6 adjusts the length of the extension of the lower support leg 62 through threaded connection. Such a setting enables the side support leg 6 to adjust the extension length to control the opening angle under specific angles. The fixing rod 7 includes a main rod 71, a sub-rod 72, and a hook 73. One end of the main rod 71 is installed in the track 8 and can slide along the track 8. The other end of the main rod 71 is threadedly connected to the sub-rod 72 to adjust the extension length of the sub-rod 72. The hook 73 is installed at the end of the sub-rod 72, is hooked on the fixing ring 621 through the hook 73, and is locked by adjusting the length between the main rod 71 and the sub-rod 72. A slider 9 is provided in the track 8. The slider 9 can slide in the track 8 and a flange for preventing the slider 9 from falling out is provided on the track 8. A first connecting ring 10 is provided on the slider 9. A second connecting ring 11 that is movably matched with the first connecting ring 10 is provided at the end of the main rod 71 close to the slider 9. The movably matched first connecting ring 10 and second connecting ring 11 can adjust the swinging angle of the fixing rod 7 and can better cooperate with the fixing ring 621. The hook 73 is connected to the end of the sub-rod 72 through a ball joint. By means of the ball joint connection, the hook 73 will not be driven when the sub-rod 72 rotates, thus facilitating the installation and tightening of the fixing ring 621. The connecting seat 5 is fixed to the side of the connecting plate 3. The end of the side support leg 6 at the rotation part is spherical.

[0017] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
