Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a splicing metal guardrail. Background Technology

[0002] Metal railings are railings made of metal materials that have both protective and decorative functions. They have high strength and hardness, and can withstand greater pressure and impact. They can be used as road railings and isolation barriers to clearly define spatial boundaries through physical separation, help maintain scene order, and play a role in safety protection.

[0003] However, the fixed height and number of horizontal bars of traditional spliced ​​metal railings mean that they can only be adapted to a single preset scenario. They lack flexibility when facing different spaces and different users, resulting in narrow scenario adaptation and poor object adaptation. Utility Model Content

[0004] The purpose of this utility model is to provide a splicing metal guardrail to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing metal guardrail, comprising a main pole and an adjustment assembly. The adjustment assembly is installed inside the main pole. The adjustment assembly includes an adjusting screw that is inserted into the bottom of the inner wall of the main pole through an annular groove. A fixing screw is threaded to the bottom of the adjusting screw. A friction pad is sleeved on the outside of the fixing screw. A connecting frame is threaded to the outside of the adjusting screw. The outside of the connecting frame and the main pole form a sliding structure through a groove.

[0006] Preferably, the inner sides of both ends of the connecting frame are connected to horizontal rails via slots, and a connecting sleeve is fitted to one side of the horizontal rail.

[0007] Preferably, the upper and lower ends of the connecting sleeve are slidably connected to an L-shaped rod via a slot, and a spring is installed on the inner side of one end of the L-shaped rod.

[0008] Preferably, the other end of the L-shaped rod is fixedly connected to a plug rod, the outer side of the plug rod and the connecting frame are connected by a slot to form a plug-in structure, and the bottom end of the plug rod and the horizontal rail are connected by a slot to form a plug-in structure.

[0009] Preferably, the bottom of the main rod is bonded with an elastic protective pad, and the top of the adjusting screw is threaded with a cap.

[0010] Preferably, a bracket is inserted into the bottom outer side of the main rod body via a friction connection, one end of the bracket is threaded with a locking screw, and the top of the bracket is threaded with a longitudinal railing, the longitudinal railing and the transverse railing forming a sliding structure through a slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The adjustable components provide a flexible height and allow for setting the number of horizontal bars as needed, improving flexibility, expanding the adaptability to different scenes and objects, and enhancing practicality. After the adjusting screw is inserted into the main body, the installation of the fixing screw makes the adjusting screw and the main body form a relatively stable rotatable structure. The increased friction pad improves stability when the adjusting screw needs to be fixed and when tightening the fixing screw. Rotating the adjusting screw allows the connecting frame to move vertically within the slot of the main body. Multiple sets of connecting frames can be installed and adjusted synchronously as needed. The horizontal bars are inserted into the slots at both ends of the connecting frame. By pulling the L-shaped rod and sliding it within the connecting sleeve rod, the connecting sleeve rod and the horizontal bars are aligned. After the insertion rod is aligned, the external force on the L-shaped rod is removed. The spring provides tension, causing the two sets of L-shaped rods to slide towards each other, allowing the insertion rod to pass through the connecting frame and insert into the horizontal bars, achieving quick connection.

[0012] 2. Two sets of brackets are spliced ​​into the slots at the bottom of the main pole, and are fixed by a locking screw passing through the hole slot of one set of brackets and connecting to the other set of threads. The longitudinal railing is inserted into the bracket slots for quick installation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, a modular metal guardrail includes a main pole 1 and an adjusting assembly 2. The adjusting assembly 2 is installed inside the main pole 1. The adjusting assembly 2 includes an adjusting screw 201 that is inserted into the bottom of the inner wall of the main pole 1 via an annular groove. A fixing screw 202 is threadedly connected to the bottom of the adjusting screw 201. A friction pad 203 is sleeved on the outer side of the fixing screw 202. A connecting bracket 204 is threadedly connected to the outer side of the adjusting screw 201. The outer side of the connecting bracket 204 and the main pole 1 form a sliding structure through a groove. The height can be flexibly adjusted by the adjusting assembly 2. The number of horizontal bars can be set according to requirements to improve flexibility, expand the adaptability of scenes and objects, and improve practicality. After the adjusting screw 201 is inserted into the main rod 1, the installation of the fixing screw 202 makes the adjusting screw 201 and the main rod 1 form a relatively stable rotatable structure. The friction pad 203 is added to improve stability when the adjusting screw 201 needs to be fixed and the fixing screw 202 is tightened. Rotating the adjusting screw 201 makes the connecting frame 204 move vertically in the slot of the main rod 1, and multiple sets of connecting frames 204 can be installed and adjusted synchronously as needed.

[0017] Furthermore, horizontal rails 205 are inserted into the inner sides of both ends of the connecting frame 204 through slots, and a connecting sleeve 206 is fitted on one side of the horizontal rails 205. The horizontal rails 205 are inserted into the slots at both ends of the connecting frame 204.

[0018] Furthermore, the upper and lower ends of the connecting sleeve rod 206 are slidably connected to an L-shaped rod 207 through a slot. A spring 208 is installed on the inner side of one end of the L-shaped rod 207. The L-shaped rod 207 slides in the slot of the connecting sleeve rod 206 by external force, and the spring 208 generates tension through elastic deformation to reset the L-shaped rod 207.

[0019] Furthermore, the other end of the L-shaped rod 207 is fixedly connected to a plug rod 209. The outer side of the plug rod 209 and the connecting frame 204 form a plug-in structure through a slot. The bottom end of the plug rod 209 and the horizontal rail 205 form a plug-in structure through a slot. After the plug rod 209 is aligned, the external force on the L-shaped rod 207 is removed. The spring 208 provides tension to make the two sets of L-shaped rods 207 slide towards each other, so that the plug rod 209 passes through the connecting frame 204 and inserts into the horizontal rail 205, realizing a quick connection.

[0020] Furthermore, an elastic protective pad 210 is bonded to the bottom of the main rod 1, and a cap 211 is threaded to the top of the adjusting screw 201. The elastic protective pad 210 provides bottom cushioning, and the cap 211 provides top protection.

[0021] Furthermore, a bracket 3 is inserted into the bottom outer side of the main pole 1 by friction. One end of the bracket 3 is threaded with a locking screw 4, and the top of the bracket 3 is threaded with a longitudinal railing 5. The longitudinal railing 5 and the horizontal railing 205 form a sliding structure through a slot. The two sets of brackets 3 are spliced ​​in the slot at the bottom of the main pole 1, and are fixed by the locking screw 4 passing through the hole slot of one set of brackets 3 and threadedly connected to the other set of brackets 3. The longitudinal railing 5 is inserted into the slot of the bracket 3 to achieve quick installation.

[0022] Working principle: In use, firstly, rotate the adjusting screw 201 to make the connecting frame 204 move vertically within the slot of the main rod 1. Multiple sets of connecting frames 204 can be installed and adjusted synchronously as needed. Secondly, after the adjusting screw 201 is inserted into the main rod 1, the installation of the fixing screw 202 makes the adjusting screw 201 and the main rod 1 form a relatively stable rotatable structure. The friction pad 203 increases stability when the adjusting screw 201 needs to be fixed and when the fixing screw 202 is tightened. Thirdly, insert the horizontal bar 205 into the slots at both ends of the connecting frame 204, and pull the L-shaped rod 207 to connect... The connecting sleeve 206 slides inside, and after the connecting sleeve 206 is attached to the horizontal railing 205, the insertion rod 209 is aligned and the external force on the L-shaped rod 207 is removed. The spring 208 provides tension so that the two sets of L-shaped rods 207 slide towards each other, so that the insertion rod 209 passes through the connecting frame 204 and is inserted into the horizontal railing 205 to achieve quick connection. In the fourth step, the two sets of brackets 3 are spliced ​​into the bottom slot of the main pole body 1, and are fixed by the locking screw 4 passing through the hole slot of one set of brackets 3 and threadedly connected to the other set of brackets 3. The longitudinal railing 5 is inserted into the slot of the bracket 3 to achieve quick installation. This completes the use of a spliced ​​metal railing.
