Description

Technical Field

[0001] This utility model relates to the field of steel pedal technology, and more specifically, to a new type of detachable and combinable steel pedal. Background Technology

[0002] In the construction industry, scaffolding is an indispensable facility. As an important component of scaffolding, the performance of steel treads directly affects construction safety and efficiency. Existing steel treads require diagonal bracing at the corners of the longitudinal and transverse outer uprights, which makes it impossible to install the standard steel treads below. This leaves a large gap in the scaffolding working layer, posing a significant risk of falls for workers during construction and walking.

[0003] To address the aforementioned issues, patent CN221321721U discloses a new type of detachable and modular scaffolding steel platform. This design eliminates the large gap left when installing steel platforms on the scaffolding working layer, thereby preventing workers from falling. It also solves the problem that existing scaffolding systems require diagonal bracing on both longitudinal and transverse outer uprights at corners, making it impossible to install the prefabricated steel platforms below, resulting in a large gap on the scaffolding working layer and a significant risk of falls for workers during construction and walking.

[0004] However, it still has some shortcomings in practical use. For example, the steel treads mentioned above can usually only be installed on scaffolding with fixed spacing. When encountering scaffolding with larger spacing, the steel treads need to be replaced, resulting in poor flexibility and practicality. In order to solve the shortcomings of the existing technology, we propose a new type of detachable and combinable steel tread. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a new type of detachable and combinable steel tread, which solves the problem that steel treads can usually only be installed on scaffolding with fixed spacing. When encountering scaffolding with larger spacing, the steel treads need to be replaced, resulting in poor flexibility and practicality.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a detachable and combinable new type steel pedal, including a steel pedal body, a telescopic adjustment component is provided on the outer side of the steel pedal body, an automatic expansion component is provided on the inner side of the telescopic adjustment component, and an anti-slip strip is fixedly installed on the upper outer surface of the steel pedal body.

[0007] The telescopic adjustment assembly includes a gantry frame, a threaded screw is rotatably connected to the inner wall of the middle part of the gantry frame, a knob is fixedly installed at one end of the threaded screw, a trapezoidal block is fixedly installed on the inner surface of the gantry frame, rectangular bars are fixedly installed on the inner walls of both sides of the gantry frame, a hook is fixedly installed at one end of the rectangular bars, and a connecting strip is fixedly installed on the outer surface of one side of the rectangular bars.

[0008] The gantry frame slides on both sides of the steel pedal body, the threaded screw is threaded to the middle of the inner wall of the steel pedal body, and the rectangular bar slides on one side of the inner wall of the steel pedal body.

[0009] The automatic expansion assembly includes a first U-shaped seat, a connecting rod rotatably connected to the inner surface of the first U-shaped seat, a second U-shaped seat rotatably connected to one end of the connecting rod, an auxiliary pedal fixedly installed on the upper outer surface of the second U-shaped seat, U-shaped frames fixedly installed on both outer surfaces of the second U-shaped seat, a first mounting post rotatably connected to the inner surface of the U-shaped frame, a spring fixedly installed on the lower inner wall of the first mounting post, a second mounting post fixedly installed at one end of the spring, fixing plates rotatably connected to both outer surfaces of the second mounting post, a connecting strip fixedly installed on one outer surface of the first U-shaped seat, an auxiliary pedal sliding on the lower outer surface of the steel pedal body, and a threaded screw rotatably connected to the middle inner wall of the first U-shaped seat.

[0010] The steel pedal body has trapezoidal grooves on both outer surfaces, the trapezoidal block slides on the outer wall of the trapezoidal groove, and one side of the steel pedal body is an inclined surface.

[0011] The first U-shaped seat has a base plate on one side, and the fixing plate is fixedly installed on the upper outer surface of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model utilizes a telescopic adjustment component, including a gantry frame. Rotating a knob causes a threaded screw to rotate on the inner wall of the steel pedal body. The rotation of the threaded screw causes the gantry frame, which is rotatably connected to its outer surface, to slide horizontally. Simultaneously, it causes the trapezoidal block and rectangular bar to slide synchronously. Then, a hook is installed on the scaffolding. By using the above structure, the telescopic adjustment of the steel pedal is achieved through the rotation of the threaded screw causing the gantry frame, trapezoidal block, and rectangular bar to slide synchronously. This facilitates the installation of the pedal and greatly improves its flexibility and practicality.

[0014] This invention utilizes an automatic expansion assembly, including a first U-shaped seat. When the threaded screw rotates, it drives the gantry to move horizontally, simultaneously causing the first U-shaped seat to move horizontally as well. This causes the auxiliary pedal to slide on the lower surface of one side of the steel pedal body. When the auxiliary pedal slides on the inclined surface of one side of the steel pedal body, the spring force causes the connecting rod to rotate on the inner surfaces of the first and second U-shaped seats. This, in turn, causes the first mounting column to rotate on the inner surface of the U-shaped frame and the second mounting column to rotate between the two fixed plates. This makes the upper outer surface of the auxiliary pedal horizontal with the upper outer surface of the steel pedal body. Using the above structure, through the horizontal movement of the first U-shaped seat and the cooperation of the connecting rod and spring, the pedal automatically expands when its length is adjusted, thus improving the safety of the pedal to a certain extent.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 4 The present invention provides a detachable and combinable new type of steel pedal, including a steel pedal body 1, a telescopic adjustment component 2 on the outer side of the steel pedal body 1, an automatic expansion component 3 on the inner side of the telescopic adjustment component 2, and an anti-slip strip 4 fixedly installed on the upper outer surface of the steel pedal body 1.

[0023] The telescopic adjustment assembly 2 includes a gantry frame 21. A threaded screw 22 is rotatably connected to the inner wall of the middle part of the gantry frame 21. A knob 23 is fixedly installed at one end of the threaded screw 22. A trapezoidal block 24 is fixedly installed on the inner surface of the gantry frame 21. Rectangular bars 25 are fixedly installed on the inner walls of both sides of the gantry frame 21. A hook 26 is fixedly installed at one end of the rectangular bars 25. A connecting bar 27 is fixedly installed on the outer surface of one side of the rectangular bars 25.

[0024] Among them, the gantry frame 21 slides on both sides of the steel pedal body 1, the threaded screw 22 is threadedly connected to the middle of the inner wall of the steel pedal body 1, and the rectangular bar 25 slides on one side of the inner wall of the steel pedal body 1.

[0025] The rotation of the threaded screw 22 drives the gantry 21, trapezoidal block 24 and rectangular bar 25 to slide synchronously, realizing the telescopic adjustment of the steel pedal, which facilitates the installation of the pedal and greatly improves its flexibility and practicality.

[0026] The automatic expansion assembly 3 includes a first U-shaped seat 31, a connecting rod 32 rotatably connected to the inner surface of the first U-shaped seat 31, a second U-shaped seat 33 rotatably connected to one end of the connecting rod 32, an attached pedal 34 fixedly installed on the upper outer surface of the second U-shaped seat 33, a U-shaped frame 35 fixedly installed on both outer surfaces of the second U-shaped seat 33, a first mounting post 36 rotatably connected to the inner surface of the U-shaped frame 35, a spring 37 fixedly installed on the lower inner wall of the first mounting post 36, a second mounting post 38 fixedly installed on one end of the spring 37, a fixing plate 39 rotatably connected to both outer surfaces of the second mounting post 38, a connecting strip 27 fixedly installed on one outer surface of the first U-shaped seat 31, the attached pedal 34 sliding on the lower outer surface of the steel pedal body 1, and a threaded screw 22 rotatably connected to the middle inner wall of the first U-shaped seat 31.

[0027] By moving the first U-shaped seat 31 horizontally in conjunction with the connecting rod 32 and the spring 37, the pedal automatically expands when its length is adjusted, which improves the safety of the pedal to a certain extent.

[0028] The steel pedal body 1 has trapezoidal grooves on both outer surfaces, trapezoidal blocks 24 slide on the outer wall of the trapezoidal grooves, and one side of the steel pedal body 1 is an inclined surface.

[0029] The first U-shaped seat 31 has a base plate on one side, and the fixing plate 39 is fixedly installed on the upper outer surface of the base plate.

[0030] The working process of this utility model is as follows:

[0031] First, install the hook 26 on one side of the steel pedal body 1 onto the scaffolding. Then, according to the spacing of the scaffolding, turn the knob 23 to drive the threaded rod 22 to rotate on the inner wall of the steel pedal body 1. The rotation of the threaded rod 22 causes the gantry 21 connected to its outer surface to slide horizontally, while simultaneously driving the trapezoidal block 24 and the rectangular bar 25 to slide synchronously. Then, install the hook 26 onto the scaffolding, thus realizing the telescopic adjustment of the steel pedal, which facilitates the installation of the pedal and greatly improves its flexibility and practicality.

[0032] When the threaded screw 22 rotates and drives the gantry frame 21 to move horizontally, it simultaneously drives the first U-shaped seat 31 to move horizontally, thereby causing the auxiliary pedal 34 to slide on the lower surface of one side of the steel pedal body 1. When the auxiliary pedal 34 slides on the inclined surface of one side of the steel pedal body 1, the elastic force of the spring 37 drives the connecting rod 32 to rotate on the inner surface of the first U-shaped seat 31 and the second U-shaped seat 33, thereby driving the first mounting column 36 to rotate on the inner surface of the U-shaped frame 35, and driving the second mounting column 38 to rotate between the two fixed plates 39, so that the upper outer surface of the auxiliary pedal 34 is horizontal with the upper outer surface of the steel pedal body 1.
