Description

Technical fields:

[0001] This utility model discloses a connecting structure for a pedal and a step stool using the pedal. Background technology:

[0002] Climbing chairs are used for indoor and outdoor climbing. Currently, climbing chairs are equipped with a footboard, which consists of a metal frame and a plastic footboard. The plastic footboard is fixed to the metal frame with multiple screws. During the production process, screw holes need to be pre-drilled at corresponding positions on the metal frame, and multiple screws need to be locked during assembly, resulting in many production steps and low assembly efficiency.

[0003] Alternatively, if the pedal is made entirely of plastic, then a larger amount of plastic will be used, resulting in higher production costs. Summary of the Invention:

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a pedal connection structure and a step stool using the pedal, which facilitates assembly and reduces manufacturing costs.

[0005] The connecting structure of the pedal of this utility model is characterized by: including a frame body and a pedal with bending performance disposed on the upper part of the frame body, the upper part of the frame body is provided with limiting buckles on two opposite sides, the limiting buckles and the upper parts of the two opposite sides of the frame body form a gap space, the edges of the two opposite sides of the pedal are inserted and limited in the gap space, and the lower surface of the pedal is provided with a buckle that can be fastened to the frame body to restrict the movement or disengagement of the pedal.

[0006] Preferably, the frame body includes two channel steel bars with openings spaced apart from each other and a connecting steel bar fixedly connected to the ends of the two channel steel bars, with the upper edge of the connecting steel bar forming the gap between it and the upper wing plate of the channel steel bar.

[0007] Preferably, several intermediate spacers are connected between the two channel steel bars.

[0008] Preferably, the lower part of the buckle has a wedge-shaped hook, which engages with the lower part of the connecting steel bar, channel steel bar, or intermediate spacer.

[0009] Preferably, the intermediate spacer is a metal strip or the intermediate spacer is made of square steel. The two ends of the intermediate spacer are fixed to the bottom of the grooves of the two channel steel strips, and the upper surface of the intermediate spacer forms the spacer space between the channel steel strip and the upper flange.

[0010] Preferably, at least two buckles are provided on a middle partition, the two buckles are spaced apart in the length direction of the middle partition and are arranged opposite to each other in the width direction of the middle partition to restrict the movement of the pedal along the width direction of the middle partition.

[0011] Preferably, the aforementioned foot pedal and the buckle provided on its lower surface are integrally injection molded from plastic.

[0012] Preferably, the width of the pedal in its natural state is greater than the distance between the two pairs of side limiting buckles, and the width of the pedal in its bent state under the action of external force is less than the distance between the two pairs of side limiting buckles, so that the pedal can be inserted into the space between them.

[0013] The present invention describes a climbing chair, characterized in that it includes a front support leg and a rear support leg that is rotatably hinged to the front support leg at its upper end, wherein the front support leg and the rear support leg are respectively rotatably hinged to the outer side of the aforementioned frame body.

[0014] Preferably, the outer side of the aforementioned frame is connected to the first end of a connecting strip, and the front support leg is connected to the second end of the connecting strip via the outer side of the aforementioned frame.

[0015] The production and assembly method of the pedal connection structure of this utility model involves prefabricating a frame and a pedal separately. During assembly, force is applied along the width direction of the pedal to bend it, so that the width of the pedal in the bent state is less than the distance between the two pairs of side limiting buckles, allowing the pedal to be inserted into the space. After the pedal is inserted into the space, the external force is released, and the pedal is in its natural state with a width greater than the distance between the two pairs of side limiting buckles, thereby restricting the movement of the pedal in the thickness direction of the frame. At the same time, the buckles on the lower surface of the pedal can be fastened to the frame, thereby restricting the movement of the pedal in the length and width directions of the frame.

[0016] The connecting structure of this utility model pedal simplifies the production process and improves production efficiency because it eliminates the need to pre-set screw holes during production. During assembly, only one step is required (inserting the pedal into the space and simultaneously snapping the buckle on), which greatly improves assembly efficiency. In addition, the pedal does not need to be made entirely of plastic, reducing manufacturing costs. Attached image description:

[0022] The method of this utility model will be further described in detail below with reference to the embodiments. It should be noted that the protection scope of this utility model should include, but is not limited to, the technical content disclosed in this embodiment.

[0023] The connecting structure of this utility model includes a frame body 1 and a foot pedal 2 with bending performance, which is provided on the upper part of the frame body. The upper part of the frame body 1 is provided with two opposite sides of limiting buckles 3, and the limiting buckles 3 and the upper parts of the two opposite sides of the frame body form a gap space 4. The edge parts 5 of the two opposite sides of the foot pedal are inserted and limited in the gap space 4. The lower surface of the foot pedal is provided with a buckle 6 that can be fastened to the frame body to restrict the movement or disengagement of the foot pedal.

[0024] The bending performance of the pedal 2 is designed to facilitate bending, so that in its natural state, the width of the pedal is greater than the distance between the two pairs of side limiting buckles, and in the bent state under the action of external force, the width is less than the distance between the two pairs of side limiting buckles, so that the pedal can be inserted into the space.

[0025] One embodiment is: the frame body 1 can be in the shape of a rectangular ring (which can be formed by welding square steel), and another limiting buckle 3 is fixedly installed on the frame body 1. The buckle 6 (which can be integrally molded with the foot pedal 2 by plastic injection) can be fastened on the lower surface of the inner end of the frame body 1.

[0026] A preferred embodiment is as follows: The frame body 1 includes two channel steel bars 7 with openings spaced apart from each other and a connecting steel bar 8 fixedly connected to the ends of the two channel steel bars. The upper edge of the connecting steel bar and the wing plate 9 located at the upper part of the channel steel bar form the aforementioned space 4. The wing plate 9 of the channel steel bar directly forms the limiting fastener 3, making the structure simpler and easier to manufacture.

[0027] To improve structural stability, several intermediate spacers 10 are connected between the two channel steel bars 7. The intermediate spacers 10 can be metal bars (the metal bars are set vertically, that is, the width direction is consistent with the thickness direction of the frame body 1). The upper edge of the intermediate spacer 10 forms the gap space between the upper edge of the channel steel bar and the upper flange 9. Similarly, the intermediate spacers can be made of square steel. The two ends of the intermediate spacers are fixed to the bottom of the groove of the two channel steel bars, and the upper surface of the intermediate spacer forms the gap space between the upper edge of the channel steel bar and the upper flange 9.

[0028] The middle partition 10 not only connects the channel steel strip 7 to increase the structural strength and stability of the frame 1, but also the upper edge or upper surface of the middle partition 10 serves to support the pedal 2, so that the plastic pedal 2 does not need to be made thicker, saving materials.

[0029] The lower part of the aforementioned buckle has a wedge-shaped hook 11, which is attached to the lower part of the connecting steel bar, channel steel bar, or intermediate spacer.

[0030] Furthermore, in order to restrict the movement of the foot pedal 2, at least two buckles are provided on a middle partition. The two buckles are spaced apart along the length of the middle partition and are positioned opposite each other along the width or thickness of the middle partition (specifically, the front-to-back direction of the step stool) to restrict the movement of the foot pedal along the width or thickness of the middle partition.

[0031] This utility model of a climbing chair includes a front support leg A1 and a rear support leg A2 that is rotatably hinged to the front support leg at its upper end. The front support leg and the rear support leg are respectively rotatably hinged to the outer side of the aforementioned frame body 1. The climbing chair using the aforementioned pedal connection structure is more efficient and less costly to manufacture.

[0032] To facilitate climbing, an additional layer was added, namely, the first end of a connecting strip A3 is connected to the outer side of the frame 1, and the outer side of the aforementioned frame is connected between the front support leg A1 and the second end of the connecting strip A3.

[0033] The production and assembly method of the pedal connection structure of this utility model involves prefabricating a frame and a pedal separately. During assembly, force is applied along the width direction of the pedal to bend it, so that the width of the pedal in the bent state is less than the distance between the two pairs of side limiting buckles, allowing the pedal to be inserted into the space. After the pedal is inserted into the space, the external force is released, and the pedal is in its natural state with a width greater than the distance between the two pairs of side limiting buckles, thereby restricting the movement of the pedal in the thickness direction of the frame. At the same time, the buckles on the lower surface of the pedal can be fastened to the frame, thereby restricting the movement of the pedal in the length and width directions of the frame.

[0034] The connecting structure of this utility model pedal simplifies the production process and improves production efficiency because it eliminates the need to pre-set screw holes during production. During assembly, only one step is required (inserting the pedal into the space and simultaneously snapping the buckle on), which greatly improves assembly efficiency. In addition, the pedal does not need to be made entirely of plastic, reducing manufacturing costs.

[0035] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
