DETAILED DESCRIPTION

[0026] 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 in 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.

[0027] Example: See Figures 1 to 9According to an embodiment of the utility model, a technical solution is provided: a modularly assembled metal guardrail, comprising a guardrail main pole 1, a first connecting rod 2 and a second connecting rod 3 are rotatably provided at opposite ends of the guardrail main pole 1, a stud 4 is provided at the free end of the first connecting rod 2 and the second connecting rod 3, the stud 4 is threadedly connected to a fixing sleeve 5, and also comprises a blocking rod 6, which movably passes through the first connecting rod 2, and a plug-in portion 7 is formed on the bottom of the blocking rod 6. A plurality of plug-in ports 8 suitable for movably inserting the plug-in portion 7 are provided on the second connecting rod 3 along its length direction; and a locking mechanism 9, which is arranged between the blocking rod 6 and the second connecting rod 3, and can selectively fix the blocking rod 6 and the second connecting rod 3 relatively to each other to limit or allow the blocking rod 6 to move relative to the second connecting rod 3.

[0028] For the modularly assembled metal guardrail using the above structure, when the user needs to assemble multiple guardrail main poles 1, the user first rotates the first connecting rod 2 and the second connecting rod 3 on the two guardrail main poles 1 to align each pair of the first connecting rod 2 and the second connecting rod 3 in a straight line, and then uses the fixing sleeve 5 to threadably connect with the stud 4 on each pair of the first connecting rod 2 and the second connecting rod 3 to relatively fix each pair of the first connecting rod 2 and the second connecting rod 3, and then, movably inserts the blocking rod 6 into the first connecting rod 2 until the plug-in portion 7 at the bottom of the blocking rod 6 is inserted into the plug-in port 8 on the second connecting rod 3, and finally, uses the locking mechanism 9 to relatively fix the blocking rod 6 and the second connecting rod 3, thereby improving the efficiency of the user's installation of the blocking rod 6.

[0029] In this embodiment, the locking mechanism 9 includes a locking rod 10, a locking block 11 and a spring 12. The locking rod 10 movably passes through the second connecting rod 3 and extends into the plug-in port 8. The locking block 11 is arranged at one end of the locking rod 10 located in the plug-in port 8. The plug-in portion 7 is provided with a plug-in hole 18 suitable for inserting the locking block 11. The top of the locking block 11 is inclined. The spring 12 is sleeved on the locking rod 10, and the spring 12 elastically abuts against the locking block 11. When the user needs to relatively fix the blocking rod 6 and the second connecting rod 3, first, the bottom of the blocking rod 6 The plug-in portion 7 is inserted into the plug-in port 8 on the second connecting rod 3, and then, the bottom of the plug-in portion 7 will contact the inclined surface of the locking block 11. As the user applies pressure to the blocking rod 6, the plug-in portion 7 will abut the locking block 11. When the locking block 11 is abutted, it will drive the locking column to gradually move away from the second connecting rod 3. Then, the spring 12 will elastically abut the locking block 11, so that the locking block 11 is rubbed against the plug-in portion 7. Finally, the spring 12 will elastically abut the locking block 11 into the plug-in hole 18 to limit the movement of the blocking rod 6 relative to the second connecting rod 3.

[0030] In this embodiment, a limiting portion 13 is provided at one end of the locking rod 10 away from the locking block 11 to limit the locking rod 10 from being completely immersed in the plug-in port 8; after the spring 12 elastically abuts the locking block 11, the limiting portion 13 will limit the locking rod 10 from being completely immersed in the plug-in port 8 to prevent the user from having difficulty in removing the locking rod 10.

[0031] In this embodiment, a friction-enhancing sleeve 14 is sleeved on the fixing sleeve 5 ; when the user rotates the fixing sleeve 5 , the friction-enhancing sleeve 14 increases the friction between the user's palm and the fixing sleeve 5 , so that the user can rotate the fixing sleeve 5 .

[0032] In this embodiment, a friction ball 15 is provided on the top of the barrier rod 6; when the user needs to press the barrier rod 6 downward, the user holds the friction ball 15 to increase the friction between the friction ball 15 and the user's palm, making it easier for the user to press the barrier rod 6 downward.

[0033] In this embodiment, a base plate 16 is provided at the bottom of the guardrail main pole 1, and a screw hole 17 is opened on the base plate 16; when the user needs to fix or connect the guardrail main pole 1 with other planes, screws can be inserted into the screw holes 17 and then connected with other planes, which is convenient for the user to connect the guardrail main pole 1 with other planes.

[0034] Working principle: When the user needs to assemble multiple guardrail main poles 1, first rotate the first connecting rod 2 and the second connecting rod 3 on the two guardrail main poles 1 to align each pair of the first connecting rod 2 and the second connecting rod 3 in a straight line, and then use the fixing sleeve 5 to threadably connect with the stud 4 on each pair of the first connecting rod 2 and the second connecting rod 3 to relatively fix each pair of the first connecting rod 2 and the second connecting rod 3, and then, movably insert the blocking rod 6 into the first connecting rod 2 until the plug-in portion 7 at the bottom of the blocking rod 6 is inserted into the plug-in port 8 on the second connecting rod 3, and then, insert the plug-in portion 7 at the bottom of the blocking rod 6 into the plug-in port 8 on the second connecting rod 3. At this time, the bottom of the plug-in portion 7 will contact the inclined surface of the locking block 11. As the user applies pressure to the blocking rod 6, the plug-in portion 7 will abut the locking block 11. When the locking block 11 is abutted, it will drive the locking column to gradually move away from the second connecting rod 3, and then, the spring 12 will elastically abut the locking block. 11, so that the locking block 11 is rubbed against the plug-in portion 7, and finally, the spring 12 will elastically abut the locking block 11 into the plug-in hole 18 to limit the movement of the blocking rod 6 relative to the second connecting rod 3, thereby improving the efficiency of the user's installation of the blocking rod 6; after the spring 12 elastically abuts the locking block 11, the limiting portion 13 will limit the locking rod 10 from being completely immersed in the plug-in port 8 to prevent the user from having difficulty in taking out the locking rod 10; when the user rotates the fixing sleeve 5, the friction-increasing sleeve 14 will increase the friction between the user's palm and the fixing sleeve 5, so that the user can rotate the fixing sleeve 5; when the user needs to press the blocking rod 6 downward, the user holds the friction-increasing ball 15 to increase the friction between the friction-increasing ball 15 and the user's palm, so that the user can press the blocking rod 6 downward; when the user needs to fix or connect the guardrail main rod 1 to other planes, a screw can be inserted into the screw hole 17 and then connected to other planes, so that the user can connect the guardrail main rod 1 to other planes.
