DETAILED DESCRIPTION

[0021] In the description of the present utility model, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present utility model. The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0022] Example

[0023] See also Figures 1 to 5 The utility model preferably provides a technical solution: a welding-free metal guardrail, including a vertically arranged column 1, a plurality of cross bars 2 are horizontally passed through the column 1, and a positioning piece 3 for positioning the cross bars 2 is provided on the column 1. By passing a plurality of cross bars 2 through at least two columns 1 and positioning the cross bars 2 with the positioning piece 3, a single guardrail can be formed, which has a simple structure and is easy to assemble.

[0024] In this embodiment, the positioning member 3 includes a positioning pin 14 horizontally inserted on the column 1 perpendicular to the cross bar 2, a first adapting slot 20 for accommodating the cross bar 2 to pass through and a second adapting slot 17 for accommodating the positioning pin 14 to be inserted on the column 1, a pin hole 16 for plugging and adapting with the positioning pin 14 is provided on the cross bar 2, an end handle 15 is provided at one end of the positioning pin 14 located outside the column 1, a first stopper 18 is provided on the side wall of the end of the positioning pin 14 inserted into the pin hole 16, and a second stopper 19 is provided on the inner wall of the pin hole 16. The positioning pin 14 is used to pass through the second adapting slot 17 and insert into the pin hole 16 on the cross bar 2, and then the end handle 15 is held by hand to drive the positioning pin 14 to rotate, so that the first stopper 18 is aligned with the second stopper 19 inside the pin hole 16, and the positioning pin 14 is restricted from slipping out of the pin hole 16, so that the cross bar 2 can be positioned on the column 1.

[0025] Furthermore, an end of the positioning pin 14 away from the end handle 15 is connected to a first spring 21, and an end face of the first stop block 18 facing the end handle 15 is provided with a rubber pad. When the positioning pin 14 is inserted into the pin hole 16, the positioning pin 14 pushes the first spring 21 to embed into the pin hole 16 and squeeze it. The elastic force of the first spring 21 pushes the positioning pin 14 so that the rubber pad on the first stop block 18 can be pressed against the second stop block 19, thereby increasing friction and avoiding accidental rotation of the positioning pin 14 as much as possible.

[0026] As a preferred implementation scheme of this embodiment, a connecting handle 5 is provided at one end of the cross bar 2, and a connecting groove 6 capable of accommodating the connecting handle 5 to be horizontally embedded is provided at the other end. A first plugging hole 7 is provided at a position corresponding to the connecting groove 6 on the cross bar 2, and a second plugging hole 8 is provided on the connecting handle 5. A connecting rod 4 capable of passing through the second plugging hole 8 is passed through the first plugging hole 7. When the two guardrails are connected, the connecting handle 5 and the connecting groove 6 at the end of the cross bar 2 are nested with each other so that the first plugging hole 7 is aligned with the second plugging hole 8, and then the connecting rod 4 is passed through the first plugging hole 7 and the second plugging hole 8. In this way, the two guardrails can be quickly connected. This connection method facilitates the relative rotation of the two guardrails to adjust the angle.

[0027] In this embodiment, a handle 12 is provided at the top of the connecting rod 4 for easy hand-held operation, and a blocking member 13 is provided at the bottom end of the connecting rod 4. The blocking member 13 includes a cavity 22 opened at the bottom end of the inside of the connecting rod 4, a push plate 23 movably embedded in the cavity 22, a protrusion 24 provided on one side of the push plate 23, and a second spring 25 provided on the other side of the push plate 23. The second spring 25 abuts against the inner wall of the cavity 22, and the protrusion 24 penetrates the side wall of the connecting rod 4. When the connecting rod 4 is inserted into the first plug hole 7 and the second plug hole 8, the protrusion 24 is pressed and embedded in the connecting rod 4. After the protrusion 24 is released, the elastic force of the second spring 25 pushes the push plate 23 to make the protrusion 24 extend out of the surface of the connecting rod 4, which can limit the bottom end of the connecting rod 4 and prevent the connecting rod 4 from detaching from the cross bar 2.

[0028] In a further embodiment, the first plug-in hole 7 and the second plug-in hole 8 have the same aperture diameter, a pair of positioning ridges 9 are vertically arranged on the side wall of the connecting rod 4, and the inner wall of the first plug-in hole 7 is only provided with a pair of first positioning grooves 10 into which the pair of positioning ridges 9 can be inserted, and the inner wall of the second plug-in hole 8 is provided with a second positioning groove 11 into which the positioning ridges 9 can be inserted, and the second positioning grooves 11 are provided with multiple grooves around the inner wall of the second plug-in hole 8. Through this structural method, the positioning ridges 9 on the connecting rod 4 are embedded in the first positioning grooves 10 and the second positioning grooves 11, so as to position the two guardrails at different angles. By aligning the first positioning groove 10 with the second positioning grooves 11 at different positions, the two guardrails can be positioned at different angles, thereby facilitating the angle adjustment between the two guardrails.

[0029] When in use, the plurality of cross bars 2 are horizontally passed through the first adapting slots 20 on at least two columns 1, and the positioning pins 14 are used to pass through the second adapting slots 17 and inserted into the pin holes 16 on the cross bars 2. Then, the end handle 15 is held to drive the positioning pins 14 to rotate, so that the first stopper 18 is aligned with the second stopper 19 inside the pin hole 16, and the positioning pins 14 are restricted from slipping out of the pin holes 16, so that the cross bars 2 can be positioned on the columns 1, wherein the elastic force of the first spring 21 in the pin hole 16 pushes the positioning pins 14 so that the rubber pad on the first stopper 18 is pressed against the second stopper 19, thereby increasing the friction force and avoiding the positioning pins 14 from accidentally rotating as much as possible. Thus, the plurality of cross bars 2 fixed on the columns 1 and the at least two columns 1 are assembled into a single guardrail. When two adjacent guardrails are connected, the connecting handle 5 and the connecting groove 6 at the end of the cross bar 2 are nested with each other, so that the first plug The connecting hole 7 is aligned with the second plug hole 8, and then the connecting rod 4 is passed through the first plug hole 7 and the second plug hole 8, thereby, the two guardrails can be quickly connected, and this connection method is convenient for the two guardrails to rotate relative to adjust the angle. Furthermore, the positioning ridge 9 on the connecting rod 4 is embedded in the first positioning groove 10 and the second positioning groove 11, so that the two guardrails can be positioned at different angles. Since the second positioning groove 11 is provided with multiple channels around the second plug hole 8, and the first positioning groove 10 is provided with only one pair, the first positioning groove 10 is aligned with the second positioning groove 11 at different positions, so that the two guardrails can be positioned at different angles, thereby facilitating the angle adjustment between the two guardrails. The overall structure is reasonable, and a mechanical structure is used to realize the assembly of the guardrails. It has the multi-angle adjustment and positioning functions of the guardrails, high flexibility, easy assembly, and excellent performance.
