Description

Technical Field

[0001] The utility model relates to the technical field of foldable ladders, in particular to a novel step-folding ladder. Background Art

[0002] A herringbone ladder is a type of climbing tool used for decoration work in the space above the plane (such as the roof). When it is used, the front and rear ladder rods and the ground form an isosceles triangle, which looks like a "human" character, so it is figuratively called a "herringbone ladder". Practical herringbone ladders include fixed herringbone ladders and movable herringbone ladders. Fixed herringbone ladders are temporary building tools for people; movable herringbone ladders are two ladders connected at the top with loose-leaf hinges, which can be closed when moving. Due to its flexibility, it is widely used in electrical operations. Early herringbone ladders were generally made of wood. With the development of the metal industry, aluminum alloy materials are mostly used; aluminum alloy herringbone ladders are light, beautiful, durable, and inexpensive, so they are widely used.

[0003] Chinese patent document CN212803025U discloses a novel pedal folding straight ladder, which relates to the improvement of industrial and civil herringbone ladders, and specifically relates to a novel pedal folding straight ladder improvement.

The hinge mechanism is used to facilitate the opening and retraction of the ladder frame, and at the same time, it has a self-locking function, which enhances the stability and safety of the herringbone ladder. The first ladder frame bodies are hinged by anti-skid pedals, and the anti-skid pedals are hinged by two pedal pull rods, which is convenient for folding.

Moreover, when the new pedal folding ladder is unfolded for use, the supporting assembly cannot play a protective role, so that the pedal folding ladder is easy to bump against the ground when the user is using it, and it may also shift, thereby affecting safety of use.

[0023] 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.

[0025] By using the hinge mechanism inside the folding adjustment component 2, the fixed side panels 3 and the folding pedal component 4 can be easily folded when in use, and have a self-locking function, so that they are easy to use. When opened, the lower parts of the two fixed side panels 3 are supported by the support component 5, so as to play a supporting and protective role when in use.

[0026] like Figure 2 As shown, the support assembly 5 includes two fixed columns 51, the opposite surfaces of the two fixed columns 51 are fixedly connected to the opposite surfaces of the two fixed side plates 3 respectively, the outer walls of the two fixed columns 51 are rotatably connected to the support plates 52, the lower surfaces of the two support plates 52 are fixedly connected to the buffer assembly 53, and the middle parts of the opposite surfaces of the two support plates 52 are fixedly connected to the connecting plate 54 and the connecting plate 54 is located below the fixed columns 51;

[0027] Through the action of the fixing column 51, the support plate 52 and the connecting plate 54 can be rotated between the two fixed side plates 3, so as to facilitate recycling and placement when folded, thereby reducing the volume for easy transportation.

[0028] The rear sides of the upper parts of the two support plates 52 are overlapped with the limiting blocks 59, and the opposite surfaces of the two limiting blocks 59 are fixedly connected to the opposite surfaces of the two fixed side plates 3 respectively. The inner cavities of the two limiting blocks 59 are fixedly connected to the limiting rods 58, and the left and right sides of the limiting rods 58 are fixedly connected to the opposite surfaces of the two fixed side plates 3 respectively.

[0029] Through the action of the two limiting blocks 59, the support plate 52 can be restricted and fixed when it is used for supporting or folded back, thereby increasing stability.

[0030] like Figure 3 , Figure 4 As shown, a fixing ring 57 is fixedly connected to the rear of the middle part of the limiting rod 58, an elastic rope 55 is fixedly connected to the front of the middle part of the connecting plate 54, and a hook 56 is fixedly connected to the lower surface of the elastic rope 55;

[0031] When the support plate 52 rotates to between the two fixed side plates 3, the connecting plate 54 is now located above the limiting rod 58, and then the hook 56 is pulled to move downward under the action of the elastic rope 55, so that the hook 56 is hooked inside the fixing ring 57, thereby fixing the two support plates 52 when the step folding ladder is folded.

[0032] like Figure 5 As shown, the buffer assembly 53 includes a support frame 531, the upper surface of the support frame 531 is fixedly connected to the lower surface of the support plate 52, the inner cavity of the support frame 531 is slidably connected to the fixing plate 533, the upper surface of the fixing plate 533 is fixedly connected to the rubber pad 532, the outer wall of the rubber pad 532 is movably sleeved with the inner cavity of the support frame 531, the upper surface of the rubber pad 532 is fixedly connected to the lower surface of the support plate 52, the inner cavities of the front and rear parts of the rubber pad 532 are slidably connected to buffer springs 535, and the upper and lower sides of the two buffer springs 535 are fixedly connected to the opposite surfaces of the support plate 52 and the fixing plate 533 respectively;

[0036] The working principle of the utility model is as follows: by using the hinge mechanism inside the folding adjustment component 2, the fixed side plate 3 and the folding pedal component 4 can be easily folded when in use, and at the same time have a self-locking function, so as to be easy to use. When opened for use, the rubber pad 532 and the buffer spring 535 can make the fixed plate 533 have a certain buffer when supporting the support plate 52, so that it can play a buffering role when supporting the fixed side plate 3 and the folding pedal component 4. At the same time, the particle anti-skid pad 534 can make the fixed plate 533 support the support plate 5 2 and the fixed side panels 3 can increase the friction with the ground, thereby ensuring stability during use. When the fixed side panels 3 and the folding pedal assembly 4 are folded, the support plate 52 is rotated so that the support plate 52 is rotated to between the two fixed side panels 3 under the action of the fixing column 51. At this time, the connecting plate 54 is located above the limiting rod 58, and then the hook 56 is pulled to move downward under the action of the elastic rope 55, so that the hook 56 is hooked inside the fixing ring 57, so that the two support plates 52 are fixed when the pedal folding ladder is folded.
