Description

Technical Field

[0001] This utility model relates to the field of stair handrails, and in particular to a highly wear-resistant building stair handrail. Background Technology

[0002] Stair handrails are protective devices installed along the sides or one side of a staircase. They are mostly made of metal, wood, glass, or composite materials and are fixed to the stair railing or wall. The height is usually 80-110 centimeters and is consistent with the slope of the staircase. They are provided for people to hold onto when going up and down the stairs, playing a role in balancing their bodies and preventing falls. They also have a decorative function. They are commonly found in stairwells in residential and public places and are a key component of the staircase structure that ensures safe passage.

[0003] Most existing stair handrails adopt a fixed height design, which cannot be adjusted according to the needs of different people or special scenarios, thus limiting their applicability and failing to meet usage requirements. Furthermore, the surface of the handrail has poor wear resistance and is easily worn under frequent gripping and friction, affecting its service life and safety. Therefore, those skilled in the art have provided a highly wear-resistant building stair handrail to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a highly wear-resistant building stair handrail that can meet the needs of different groups of people and special scenarios. At the same time, the handrail length can be adjusted by increasing or decreasing the number of support and connection mechanisms to adapt to staircase renovations and other scenarios. The modular design makes installation and adjustment easy, taking into account both structural strength and usage flexibility.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wear-resistant building stair handrail includes multiple support mechanisms, each of which is connected by a connecting mechanism, and each connecting mechanism contains multiple reinforcing mechanisms.

[0007] Each of the multiple support mechanisms includes a fixed column and a movable column. Fixed blocks are fixedly installed on both sides of each of the multiple fixed columns and movable columns. Multiple adjustment holes are opened on one side of each of the multiple fixed columns. A slot is opened on one side of each of the multiple fixed blocks. Each of the multiple connecting mechanisms includes two connecting plates. Locking blocks are fixedly installed on both sides of each of the multiple connecting plates. Multiple insert blocks are fixedly installed on opposite sides of each of the multiple connecting plates. A fixed hole is opened at the upper end of each of the multiple locking blocks. Each of the multiple reinforcing mechanisms includes a connecting rod. Threaded rods are threadedly connected to both the upper and lower ends of each of the multiple connecting rods. A reinforcing rod is fixedly installed on the opposite side of each of the multiple threaded rods.

[0008] Furthermore, each of the aforementioned fixed columns has a base fixedly installed at its lower end.

[0009] Furthermore, all of the movable columns are slidably sleeved on the upper end of the fixed column.

[0010] Furthermore, each of the multiple movable columns is threaded with a first fixing bolt on one side.

[0011] Furthermore, each of the aforementioned fixing blocks has a second fixing bolt threaded onto its upper end.

[0012] Furthermore, all of the aforementioned card blocks are inserted into the card slot.

[0013] Furthermore, all of the connecting rods are inserted into the insert block.

[0014] Furthermore, the outer surfaces of the support mechanism, connecting mechanism, and reinforcing mechanism are all coated with tungsten carbide.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a highly wear-resistant building stair handrail. The support mechanism achieves flexible height adjustment of the handrail through the sliding cooperation of fixed columns and movable columns. After pulling the movable column to the appropriate position, the height can be locked by inserting the first fixing bolt into the corresponding adjustment hole. It can meet the usage needs of different people and special scenarios. The base is fixed to the side of the stair or the ground by expansion bolts, providing solid support for the entire handrail structure. The cooperation between the fixing block and the slot provides a precise docking foundation for the connection mechanism, ensuring the dual stability of support and connection, and improving the safety of handrail use.

[0017] 2. This utility model proposes a highly wear-resistant building stair handrail. The connecting mechanism connects adjacent support mechanisms through the insertion and engagement of a locking block and a locking slot. A second fixing bolt passes through a fixing hole for further tightening. The handrail is formed by mating with the locking block to increase the connection contact area and enhance stability. After the connecting rod of the reinforcing mechanism is inserted into the locking block, the threaded rod is rotated to make the reinforcing rod press against the inner wall of the locking block. The strength of the connection part is strengthened by the extrusion force, which effectively prevents loosening. At the same time, the handrail length can be adjusted by increasing or decreasing the number of support mechanisms and connecting mechanisms to adapt to staircase renovations and other scenarios. Furthermore, the outer surfaces of the support mechanism, connecting mechanism, and reinforcing mechanism are all coated with tungsten carbide, which significantly improves the overall wear resistance of the handrail and extends its service life.

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1-4 One embodiment of this utility model is a wear-resistant building stair handrail, which includes multiple support mechanisms 1, a connecting mechanism 2 between the multiple support mechanisms 1, multiple reinforcing mechanisms 3 inside the multiple connecting mechanisms 2, and a tungsten carbide coating on the outer surface of the support mechanisms 1, the connecting mechanisms 2 and the reinforcing mechanisms 3.

[0026] Specifically, the support mechanism 1 provides stable support for the handrail and is height-adjustable; the connecting mechanism 2 connects adjacent support mechanisms 1 to form a continuous handrail structure; the reinforcing mechanism 3 enhances the strength and stability of the connecting parts, ensuring the stability of the handrail during use; and the tungsten carbide coating has extremely high hardness and wear resistance, effectively resisting frictional wear generated during long-term use, significantly improving the overall wear resistance of the handrail, and extending its service life.

[0027] Reference Figure 1 , Figure 2Each of the multiple support mechanisms 1 includes a fixed column 103 and a movable column 108. The lower end of each of the multiple fixed columns 103 is fixedly provided with a base 101. The fixed blocks 102 are fixedly provided on both sides of the multiple fixed columns 103 and the movable columns 108. Multiple adjustment holes 104 are opened on one side of each of the multiple fixed columns 103. The slots 106 are opened on one side of each of the multiple fixed blocks 102. The multiple movable columns 108 are slidably sleeved on the upper end of the fixed columns 103. The first fixing bolt 105 is threadedly connected to one side of each of the multiple movable columns 108. The second fixing bolt 107 is threadedly connected to the upper end of each of the multiple fixed blocks 102.

[0028] Specifically, in the support mechanism 1, the base 101 fixes the support mechanism 1 to the side of the stairs or the ground. The sliding cooperation between the fixed column 103 and the movable column 108 can adjust the height of the handrail. The height is locked by inserting the first fixing bolt 105 into different adjustment holes 104. The slot 106 on the fixing block 102 is used to connect the mechanism 2. The second fixing bolt 107 is used to fix the connection part.

[0029] Reference Figure 1 , Figure 3 , Figure 4 Each of the multiple connecting mechanisms 2 includes two connecting plates 202. Each of the multiple connecting plates 202 has a locking block 201 fixedly installed on both sides. Each of the multiple connecting plates 202 has a locking block 203 fixedly installed on the opposite side. Each of the multiple locking blocks 201 has a fixing hole 204 at its upper end. Each of the multiple locking blocks 201 is inserted into the slot 106. Each of the multiple reinforcing mechanisms 3 includes a connecting rod 303. Each of the multiple connecting rods 303 has a threaded rod 302 threadedly connected to its upper and lower ends. Each of the multiple threaded rods 302 has a reinforcing rod 301 fixedly installed on the opposite side. Each of the multiple connecting rods 303 is inserted into the locking block 203.

[0030] Specifically, in the connecting mechanism 2, the adjacent support mechanism 1 is connected by the insertion and engagement of the locking block 201 and the locking slot 106. The second fixing bolt 107 passes through the fixing hole 204 to achieve fastening. The two connecting plates 202 are joined together by the insert block 203 to form a complete handrail. In the reinforcing mechanism 3, the connecting rod 303 is inserted into the insert block 203. The threaded rod 302 is rotated to make the reinforcing rod 301 press against the inner wall of the insert block 203 to enhance the connection strength.

[0031] Working principle: During installation, first fix the base 101 of the support mechanism 1 to the side of the stairs or the ground. Adjust the height of the movable column 108 according to the usage requirements. Pull the movable column 108 upward and slide it along the fixed column 103. After aligning with the appropriate adjustment hole 104, tighten the first fixing bolt 105 to lock the height. Next, install the connecting mechanism 2. Insert the locking blocks 201 on both sides of the connecting plate 202 into the locking slots 106 of the adjacent support mechanism 1, so that the fixing hole 204 is aligned with the threaded hole of the fixing block 102. Tighten the second fixing bolt 107 to complete the fixation. The two connecting plates 202 are connected by the inserts 203 on opposite sides to form a continuous handrail structure. To enhance the connection strength, insert the connecting rod 303 of the reinforcing mechanism 3 at the connection point of the inserts 203. Rotate the threaded rods 302 at both ends to make the reinforcing rod 301 expand outward and press against the inserts 203. The inner wall of the support mechanism 1 prevents the connecting plate 202 from loosening through friction and support, thus improving the overall structure's resistance to deformation. During use, the fixed column 103 and the moving column 108 of the support mechanism 1 form a stable support. The connecting plate 202 of the connecting mechanism 2 provides a gripping surface as the main body of the handrail. The reinforcing mechanism 3 enhances the strength of the connecting parts through mechanical locking. The tungsten carbide coating on the outer surface of each mechanism works together to significantly improve the overall wear resistance of the handrail, ensuring that the handrail is not easily shaken or damaged during long-term use. If the handrail length needs to be adjusted, simply increase or decrease the number of support mechanisms 1 and connecting mechanisms 2 to adapt to the length requirements of different staircases. This design effectively improves the load-bearing capacity of the handrail and the wear resistance of the connecting parts through modular splicing and reinforced structure. It also features adjustable height and flexible length adaptation, making it suitable for various building staircase scenarios.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
