Description

Technical Field

[0001] This utility model relates to the field of metal railing technology, specifically to a metal railing. Background Technology

[0002] Existing metal railings typically connect the top and bottom horizontal bars and the guardrails together by welding or other methods, and then bolt them through pre-drilled holes to a fixed mounting base. After installation, the railing height is not adjustable. Due to the possibility of a base or other conditions at the installation site, the railing height may not meet requirements. Furthermore, because the top and bottom horizontal bars and guardrails are integrated, maintenance is inconvenient. If one guardrail is damaged, the gaps between the guardrails become too large, rendering them ineffective and affecting the basic functionality of the railing. Utility Model Content

[0003] The technical problem this invention aims to solve is that the height of the railing is not adjustable, resulting in poor practicality; the upper horizontal bar, lower horizontal bar, and stop bar are integrated, making maintenance inconvenient and reducing service life.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a metal railing, including a base, an upper horizontal bar, a lower horizontal bar, and stop bars evenly distributed between the upper and lower horizontal bars. The top of the base is slidably provided with a mounting seat, and the mounting seat is provided with a height adjustment component that can drive the mounting seat to slide up and down. The mounting seat is evenly provided with a plurality of limiting grooves around its circumference. The ends of the upper and lower horizontal bars are respectively provided with limiting blocks that cooperate with the limiting grooves. The stop bars are telescopically positioned, and the upper and lower horizontal bars are provided with rotating grooves that cooperate with the stop bars.

[0005] Furthermore, the height adjustment component includes a screw located within the base, a drive rod rotatably passing through the mounting base, a drive block at the top of the drive rod, and a threaded groove at the bottom that engages with the screw thread.

[0006] Furthermore, there are no fewer than four sets of limiting grooves.

[0007] Furthermore, the stop bar includes a sleeve rod and an inner rod arranged concentrically. The inner rod is provided with a locking block. The sleeve rod is provided with a circular groove that cooperates with the inner rod. The inner wall of the sleeve rod is provided with a guide groove along the axial direction. The guide groove is provided with a plurality of locking grooves that can cooperate with the locking block for positioning.

[0008] Furthermore, both the sleeve rod and the inner rod have rotating blocks at their free ends that mate with the rotating groove.

[0009] Furthermore, the guide groove is provided through the open end of the sleeve rod.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0011] 1. The height of the mounting base is adjusted by driving the mounting base to slide up and down along the base through the height adjustment component. The mounting base drives the upper crossbar, lower crossbar and stop bar to move up and down, so that the height can be adjusted as needed. This avoids the upper crossbar being too low to provide adequate protection, and also avoids the upper crossbar being too high to obstruct the field of vision.

[0012] 2. The separate design of the upper crossbar, lower crossbar, and stop bar facilitates the maintenance of each component, while the telescopic positioning of the stop bar facilitates the disassembly and maintenance of the stop bar, thereby extending the overall service life of the device.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Combined with appendix Figure 1 and attached Figure 2 A metal railing includes a base 1, an upper crossbar 2, a lower crossbar 3, and stop bars 4 evenly distributed between the upper crossbar 2 and the lower crossbar 3. The base 1 is slidably provided with a mounting seat 5 on its top, and the mounting seat 5 is evenly provided with a plurality of limiting grooves 7 around its circumference. The ends of the upper crossbar 2 and the lower crossbar 3 are respectively provided with limiting blocks 8 that cooperate with the limiting grooves 7.

[0020] Traditional metal railings typically consist of an upper horizontal bar 2, a lower horizontal bar 3, and a stop bar 4, which are usually fixed together by welding or other methods. If any one of these components is damaged, the gaps between the stop bars 4 may become too large, resulting in a loss or reduction of the barrier effect.

[0021] In this application, the upper crossbar 2, lower crossbar 3 and stop bar 4 are separated. The upper crossbar 2 and lower crossbar 3 are installed by the limit block 8 cooperating with the limit groove 7 on the mounting base 5 at both ends. Since the stop bar 4 is telescopically positioned, it is easy to maintain and thus extend the service life of the device.

[0022] Meanwhile, the limiting grooves 7 are evenly distributed around the mounting base 5. In this application, eight sets are used, so that the upper crossbars 2 and lower crossbars 3 on both sides of the mounting base 5 can cooperate with the limiting grooves 7 at different angles according to actual installation needs, thereby improving the practicality of the device.

[0023] Combined with appendix Figure 3 and attached Figure 4 The stop lever 4 is telescopically positioned. The stop lever 4 includes a sleeve rod 13 and an inner rod 14 arranged concentrically. The inner rod 14 is provided with a locking block 15. The sleeve rod 13 is provided with a circular groove 16 that cooperates with the inner rod 14. The inner wall of the sleeve rod 13 is provided with a guide groove 19 along the axial direction. The guide groove 19 is provided through the open end of the sleeve rod 13. Several locking grooves 17 that can cooperate with the locking block 15 for positioning are evenly distributed on the guide groove 19.

[0024] Combined with appendix Figure 3 The upper crossbar 2 and the lower crossbar 3 are provided with rotating grooves 9 that cooperate with the stop bar 4. The free ends of the sleeve bar 13 and the inner bar 14 are provided with rotating blocks 18 that cooperate with the rotating grooves 9.

[0025] During installation, since the width of the guide groove 19 matches the width of the locking block 15, first, hold the inner rod 14 with one hand and the sleeve rod 13 with the other hand, so that the locking block 15 of the inner rod 14 is guided along the through end of the guide groove 19 and slid to the bottom of the guide groove 19, so that the length of the stop rod 4 is less than the distance between the upper crossbar 2 and the lower crossbar 3.

[0026] Then, the rotating blocks 18 at the free ends of the inner rod 14 and the sleeve rod 13 are aligned with the rotating groove 9, and the inner rod 14 and the sleeve rod 13 are driven to separate up and down, so that the rotating blocks 18 at the free ends of the inner rod 14 and the sleeve rod 13 respectively cooperate with the corresponding rotating groove 9, wherein the rotating blocks 18 are cylindrical structures.

[0027] At this time, rotating the inner rod 14 and the sleeve rod 13 causes the locking block 15 on the inner rod 14 to be guided into the locking groove 17 and cooperate with it, thereby connecting and positioning the inner rod 14 and the sleeve rod 13.

[0028] Combined with appendix Figure 2The mounting base 5 is provided with a height adjustment component 6 that can drive the mounting base 5 to slide up and down. The height adjustment component 6 includes a screw 10 located in the base 1, and a drive rod 11 is rotatably provided inside the mounting base 5. The top end of the drive rod 11 is provided with a drive block 12, and the bottom end is provided with a threaded groove that is threadedly engaged with the screw 10.

[0029] Traditional metal railings have a fixed height after the upper horizontal bar 2 and lower horizontal bar 3 are installed with the mounting base 5, and cannot be adjusted. If the installation height is too low, it will not have a blocking and protective effect; if the installation height is too high, it will affect the field of vision.

[0030] To improve the applicability to the installation site and avoid excessively high or low conditions, the drive block 12 can be rotated. The drive block 12 drives the drive rod 11 to rotate, and the drive rod 11 drives the mounting base 5 to slide up and down along the base 1 through the threaded engagement with the screw 10, so as to meet the actual use needs.
