Abstract
Description
Technical Field
[0001] The utility model relates to the field of bedding, in particular to a leak-proof welding pedal. Background Art
[0002] In order to save space, dormitory bunk beds are usually used. A fixed escalator is connected between the bed frames of the upper and lower bunks for bunking. Existing fixed escalators are usually made of metal materials to ensure the safety of users. The current structure of fixed escalators is mainly to weld steel pedals directly to the left and right columns of the escalator. This method has the following defects in practice. During the welding process, it is easy to have false welding and poor welding, which is difficult to detect during product inspection. Once the weld breaks during use, safety accidents such as people falling will directly occur. Therefore, in order to solve the above problems, a leak-proof pedal is needed. Utility Model Content

[0010] A card interface is provided on the column, and a locking piece adapted to the card interface structure is provided in the limit opening;
[0011] When the upright post is inserted into the limiting opening, the locking piece is buckled into the card interface.
[0012] In order to better implement the utility model, it can be further provided that: the two ends of the pedal are respectively welded to the upright posts on the corresponding sides.
[0013] Furthermore: an indication groove is provided in the middle of the upper surface of the pedal, and an indication sign is placed in the indication groove.
[0014] Furthermore: the surface of the pedal is covered with an anti-slip layer.
[0015] Furthermore: the cross section of the column is an elliptical structure.
[0016] Furthermore, the column includes a supporting section and a bending section, the bending section is bent relative to the supporting section, a fixing plate is connected to the free end of the bending section, and a fixing hole is opened in the fixing plate.
[0017] The beneficial effects of the utility model are as follows: the overall structure is simple, and limiting openings corresponding to the structure of the column are respectively provided at both ends of the pedal, and the column is inserted into the limiting openings; a card interface is provided on the column, and a locking piece adapted to the card interface structure is provided in the limiting opening, and a locking piece is designed on the pedal, and during production, the locking piece is inserted into the card interface, and is welded in a normal manner during production. If a poor welding method causes the weld to break during use, the presence of the locking piece will prevent the pedal from falling, and can effectively ensure safe use.

[0026] like Figures 1 to 5 As shown:
[0027] A leak-proof pedal 2 includes a support frame and a pedal 2. A plurality of pedals 2 are arranged along the length direction of the support frame. The support frame includes two oppositely arranged columns 1. The pedal 2 is fixedly connected between the two columns 1. Specifically, the two ends of the pedal 2 are respectively welded to the columns 1 on the corresponding sides. Limiting openings 3 corresponding to the structure of the column 1 are respectively provided at the two ends of the pedal 2, so that the column 1 is inserted into the limiting openings 3. A card interface 4 is provided on the column 1. A locking piece 5 adapted to the structure of the card interface 4 is provided in the limiting opening 3. When the column 1 is inserted into the limiting opening 3, the locking piece 5 can be inserted into the card interface 4. The column 1 includes a support section 9 and a bending section 10.
