Description

Technical Field

[0001] The utility model relates to the technical field of pedal devices, in particular to a telescopic construction pedal. Background Art

[0002] Construction pedals are an important part of the scaffolding system, used to provide a platform for workers to stand, walk and operate. Construction pedals are usually made of metal (such as aluminum alloy, steel) or plastic and have a certain load-bearing capacity and stability. Construction pedals are widely used in construction, maintenance, decoration and other projects, and are one of the important equipment to ensure the safety and efficiency of workers.

[0003] In the existing patent literature, there is a patent document with the announcement number CN 202467155U and the patent name "A telescopic scaffolding pedal". The existing technology mainly adjusts the overall length of the pedal by tightening screws, and places it on the scaffolding steel pipe through a hook. When the tightening screws and the screw holes are fixed, it can only ensure that the hook can be placed just on the scaffolding steel pipe, but cannot ensure that the hook is clamped on the scaffolding steel pipe. Therefore, when the staff steps on the pedal, it is easy to shake or vibrate, which leads to certain safety hazards and affects the staff's sense of security. Utility Model Content

DETAILED DESCRIPTION

[0039] 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 of 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.

[0040] like Figures 1 to 12 As shown, a telescopic construction pedal comprises a plate body 1 and a plate body 2, and the facing ends of the plate body 1 and the plate body 2 are respectively fixed with a plurality of telescopic frames 1 3 and a telescopic frame 2 4 distributed in a linear array, and the telescopic frame 1 3 and the telescopic frame 2 4 are slidably connected by a linear slide rail 5 fixed on the side wall of the telescopic frame 1 3, and the telescopic frames 1 3 and the telescopic frames 2 4 are staggered and together constitute the treading surface of the construction pedal;

[0041] A clamping and positioning seat 6 is fixed to the lower surface of the plate body 1 and the plate body 2, respectively. A clamping cavity 7 is provided inside the clamping and positioning seat 6. The opening end of the clamping cavity 7 faces the end of the plate body 1 away from the telescopic frame 3 or the end of the plate body 2 away from the telescopic frame 2 4. A telescopic adjustment mechanism 8 is fixedly installed on the lower surface of the plate body 1 and the plate body 2;

[0042] The telescopic adjustment mechanism 8 includes a storage tube 801, one end of which is movably mounted with a telescopic adjustment seat 802, the inner side of which is rotatably connected to the storage tube 801 via an annular slider 803, a screw sleeve 804 is fixed to the end of the telescopic adjustment seat 802, a telescopic screw 805 is threadedly engaged in the screw sleeve 804, and the telescopic screw 805 can be hidden in the storage tube 801, and the telescopic screw 805 and the storage tube 801 are fixedly connected to the plate body 1 and the plate body 2 2 via a mounting seat 806 respectively;

[0043] The telescopic construction pedal is installed on a horizontally arranged scaffolding steel pipe 15 , and the scaffolding steel pipe 15 is clamped in the clamping cavity 7 of the clamping positioning seat 6 .

[0044] The construction pedal as a whole is telescopic and adjustable. When in use, the distance between the plate body 1 and the plate body 2 2 can be adjusted through the telescopic adjustment mechanism 8. While adjusting the distance, the clamping and positioning seats 6 under the plate bodies 1 and 2 are clamped on the scaffolding steel pipe 15, so that there will be no shaking or vibration when the workers step on the pedal. The pedal has higher stability and the workers will feel more at ease when stepping on it.

[0045] like Fig.10 and Fig.12 As shown, a plurality of rotating rods 807 distributed in a circular array are fixed on the outer side wall of the telescopic adjustment seat 802 .

[0046] In order to facilitate the rotation of the telescopic adjustment seat 802, a rotating rod 807 is provided to drive the synchronous rotation of the telescopic adjustment seat 802. When the telescopic adjustment mechanism 8 is used, the synchronous rotation of the screw sleeve 804 can be achieved by driving the telescopic adjustment seat 802 to rotate. Under the action of the thread, the telescopic screw 805 can be driven to move linearly, thereby achieving shortening or lengthening; when the telescopic screw 805 is shortened, the length of the construction pedal can be reduced, which is convenient for storing and placing the construction pedal; when the telescopic screw 805 is extended, the length of the construction pedal can be increased, thereby increasing the distance between the plate body 1 and the plate body 2, until the clamping cavity 7 of the clamping positioning seat 6 is completely clamped on the scaffolding steel pipe 15, and the adjustment of the telescopic adjustment mechanism 8 can be completed.

[0047] like Fig.10 and Fig.12 As shown, an L-shaped self-locking seat 808 is also fixed on the storage tube 801, and a self-locking top screw 809 is threaded through the L-shaped self-locking seat 808, and the thread head of the self-locking top screw 809 can contact the outer wall of the telescopic adjustment seat 802.

[0048] In order to prevent the telescopic adjustment seat 802 from rotating when not in use, the telescopic adjustment seat 802 can be locked by rotating the self-locking top screw 809 and tightening the telescopic adjustment seat 802 through the self-locking top screw 809.

[0049] like Figure 7 and Figure 8 As shown, the bottom surface of the clamping cavity 7 is an inclined slope, and the distance between the top surface and the bottom surface of the clamping cavity 7 gradually decreases from the opening end inward; wherein, the top surface and the bottom surface of the clamping cavity 7 are both provided with a plurality of anti-slip grooves 9 distributed in a linear array.

[0050] In order to achieve the clamping and fixing of the scaffolding steel pipe 15 by the clamping cavity 7, after the scaffolding steel pipe 15 is clamped in the clamping cavity 7 with a gradually decreasing opening, the anti-slip groove 9 can be used to further enhance the clamping effect.

[0051] like Figure 7 and Figure 8 As shown, a safety needle 10 is installed through the bottom surface of the open end of the clamping cavity 7, and a guide seat 11 is fixed to the bottom of the safety needle 10. The guide seat 11 is slidably installed on a guide shaft 12 fixed on the clamping positioning seat 6, and a spring 13 is mounted on the guide shaft 12 to push the guide seat 11 to slide upward; when the spring 13 pushes the guide seat 11 to contact the bottom of the clamping positioning seat 6, the needle head of the safety needle 10 can contact the top of the open end of the clamping cavity 7; wherein, a pull ring 14 is also fixed to the lower surface of the guide shaft 12.

[0052] In order to prevent the scaffolding steel pipe 15 from escaping from the clamping cavity 7 , a safety pin 10 is provided. The safety pin 10 can block the open end of the clamping cavity 7 , thereby effectively preventing the scaffolding steel pipe 15 from escaping from the clamping cavity 7 .

[0053] The working principle of this utility model:

[0054] When in use, the telescopic adjustment mechanism 8 is used to adjust the overall length of the construction pedal. By driving the telescopic adjustment seat 802 to rotate, the screw sleeve 804 can be rotated synchronously. Under the action of the thread, the telescopic screw 805 can be driven to move linearly, thereby increasing the distance between plate body 1 and plate body 2 2, until the clamping cavity 7 of the clamping positioning seat 6 is completely clamped on the scaffolding steel pipe 15, and the installation of the construction pedal is completed.

[0055] When installing the above-mentioned construction pedal, a weight can be used to hang on the pull ring. At this time, under the action of the gravity of the weight, the safety pin 10 can be pulled down, so as not to affect the scaffolding steel pipe 15 from entering the clamping cavity 7. After the scaffolding steel pipe 15 is clamped in the clamping cavity 7, the weight can be removed, and the safety pin 10 moves up under the elastic push of the spring 13. The safety pin 10 can block the open end of the clamping cavity 7, which can effectively prevent the scaffolding steel pipe 15 from escaping from the clamping cavity 7.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
