Description

Technical Field

[0001] The utility model relates to the technical field of building railing assembly, and particularly relates to a building railing convenient for assembly. Background Technique

[0002] At present, the railings on existing buildings are usually welded and supported by a fixed frame. The fixed area is divided into independent spaces by the railings, so as to play a protective role. In actual use, special tools are required for installation, which is time-consuming and laborious, increasing the labor of users to install the railings, reducing the installation efficiency of the railings, and also reducing the practicability of the building railings. Therefore, a building railing convenient for assembly appears on the market.

[0003] For example, the existing patent (Publication No.: CN213087663U) discloses a building railing convenient for assembly. By setting the fixed frame and the mechanism in the fixed frame to cooperate with each other and limit the position while stretching the spring to store energy and reset, and finally the fixed frame clamps the railing body to complete the fixation, the effect of convenient assembly is achieved, and the problem that most of the existing building railings are connected and fixed by bolts and require special tools for installation and are time-consuming and laborious is solved.

[0004] However, the above-designed building railing convenient for assembly still has some disadvantages in actual use: Although the device can solve the problem of time-consuming and laborious installation during welding, the size inside the fixed frame is fixed, and the size of the building railing adapted is also fixed. If a railing with a relatively thick body material is encountered, it cannot be used, and if a railing with a relatively thin material is encountered, the clamping will be unstable. In specific use, the application range is small, and there is a large installation constraint.

[0005] Therefore, we designed a building railing convenient for assembly to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a building railing convenient for assembly to solve the problems put forward in the above background technique.

[0007] To solve the above technical problems, a building railing convenient for assembly provided by the utility model includes a column body. A fixed box is fixedly installed on one side of the column body. A placement groove for placing the railing body is opened in the fixed box. The width of the placement groove is greater than the width of the railing body. Two clamping blocks are symmetrically and movably arranged in the fixed box. The clamping blocks are in contact with the railing body. A bolt is movably installed on the opposite sides of the two clamping blocks. One end of the bolt is in contact with one side of the clamping block. The bolt is threadedly inserted into one side of the fixed box.

[0008] Furthermore, two cavities and fixing openings are symmetrically formed in the fixing box. The cavities communicate with the fixing openings. The clamping blocks are slidably inserted into the fixing openings. The formation of the fixing openings makes it easier for the cavities to slide. The bottom of the sliding opening is flush with the placement groove to prevent movement interference during the sliding clamping process.

[0009] Furthermore, sliding components are arranged at both the top and bottom of the clamping blocks. The sliding components include limiting rods, sliders, return springs, and connecting rods. Both ends of the limiting rods are fixedly arranged in the fixing box. The sliders are movably sleeved on the limiting rods. The two ends of the return springs are respectively connected to the sliders and the fixing box. The connecting rods are fixedly installed at the bottom of the limiting rods, and the other ends of the connecting rods are connected to the clamping blocks. The setting of the moving components can assist the sliding of the clamping blocks. The limiting rods play a certain limiting role to prevent the problem of moving deviation during the sliding process. When the railing body is disassembled, it rebounds due to the elastic force of the return spring itself, driving the clamping blocks to slide back to their positions in the cavities. When assembling a new building railing, there is no need to manually adjust the clamping blocks, which improves the convenience during work.

[0010] Furthermore, two storage cavities and installation openings are symmetrically formed on both sides inside the fixing box. The sliders are slidably arranged in the storage cavities. The connecting rods are slidably inserted into the installation openings. Both ends of the limiting rods are fixedly installed in the installation openings. The two ends of the return springs are respectively connected to the sliders and the side walls of the storage cavities. The formation of the storage cavities separates the moving components from the cavities, which can prevent the occurrence of movement interference that the moving components may cause to the cavities.

[0011] Furthermore, handles are fixedly arranged on the bolts. The number of the handles is two, and the two handles are respectively arranged at the top and bottom of the bolts. The setting of the handles can make it more convenient to rotate the bolts, saving time and effort. There is no need to specifically use tools adapted to the bolts for knob operation, which is more convenient.

[0012] Furthermore, anti-slip particles are arranged on the outer surfaces of the handles to increase the friction force and prevent slipping, increasing the friction force between the hand and the handles, preventing the problem of hand slipping during the rotation process, and making the rotation process more stable.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. When assembling a building railing, place the railing body in the placement groove. If the railing body is relatively thin and there is a certain gap in the placement groove, rotate the handle clockwise to drive the bolt to rotate inward, pushing the clamping blocks to move towards the middle and clamping the railing body, which can play a role in stable clamping. If the building railing body is relatively thick, put the railing body into the placement groove and only slightly rotate the bolt to clamp and fix it, enhancing a certain stability. The applicable range is wider, and the operation steps and methods are also simpler and more concise, improving work efficiency.

[0014] 2. While the cavity moves towards the middle, the cavity slider slides on the limiting rod, and the limiting rod plays a certain limiting role to prevent deviation during the sliding process. During the sliding process, the return spring on one side of the slider is stretched and tightened, which can also play a limiting role to a certain extent. When disassembling the building railing, rotate the handle counterclockwise to remove it. At this time, due to the elastic force of the return spring itself, it rebounds, driving the clamping block to slide back to its position in the cavity. When assembling a new building railing, there is no need to manually adjust the clamping block, which improves the convenience during work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a building railing convenient for assembly, including a column 1, a fixed box 2 is fixedly installed on one side of the column 1, a placement groove 13 for placing the railing body 3 is opened in the fixed box 2, the width of the placement groove 13 is greater than the width of the railing body 3, two clamping blocks 4 are symmetrically and movably arranged in the fixed box 2, the clamping blocks 4 are in contact with the railing body 3, bolts 14 are movably installed on the opposite sides of the two clamping blocks 4, one end of the bolt 14 is in contact with one side of the clamping block 4, and the bolt 14 is threadedly inserted into one side of the fixed box 2.

[0021] Two cavities 5 and fixing ports 12 are symmetrically opened in the fixed box 2, the cavities 5 communicate with the fixing ports 12, and the clamping blocks 4 are slidably inserted into the fixing ports 12.

[0022] During specific implementation, when assembling a building railing, the railing body 3 is placed in the placement groove 13. If the railing body 3 is relatively thin, there will be a certain gap in the placement groove 13. Rotating the handle 15 clockwise drives the bolt 14 to rotate inward, pushing the clamping block 4 to move towards the middle and clamping the railing body 3, which can play a role in stable clamping. If the building railing body 3 is relatively thick, when the railing body 3 is placed in the placement groove 13, only slightly rotating the bolt 14 can clamp and fix it, enhancing a certain stability. The applicable range is wider, and the operation steps and methods are also simpler and more concise, improving work efficiency.

[0023] Refer to Figures 1-3 As shown in the figure, sliding components are arranged at both the top and bottom of the clamping block 4. The sliding components include a limiting rod 6, a slider 7, a return spring 8, and a connecting rod 9. Both ends of the limiting rod 6 are fixedly arranged in the fixed box 2. The slider 7 is movably sleeved on the limiting rod 6. The two ends of the return spring 8 are respectively connected to the slider 7 and the fixed box 2. The connecting rod 9 is fixedly installed at the bottom of the limiting rod 6, and the other end of the connecting rod 9 is connected to the clamping block 4.

[0024] On both sides inside the fixed box 2, two storage cavities 11 and installation openings 10 are symmetrically opened. The slider 7 is slidably arranged in the storage cavity 11. The connecting rod 9 is slidably inserted into the installation opening 10. Both ends of the limiting rod 6 are fixedly installed in the installation opening 10. The two ends of the return spring 8 are respectively connected to the slider 7 and the side wall of the storage cavity 11.

[0025] During specific implementation, while the cavity 5 moves towards the middle, the sliders 7 at the top and bottom of the cavity 5 slide on the limiting rod 6. The limiting rod 6 plays a certain limiting role to prevent problems such as moving deviation during the sliding process. The connecting rod 9 also slides in the installation opening 10 to assist the movement of the clamping block 4. During the sliding process, the return spring 8 on one side of the slider 7 is stretched and tightened, which can also play a limiting role to a certain extent. When disassembling the building railing, rotate the handle 15 counterclockwise and remove the handle 15. At this time, due to the elastic force of the return spring 8 itself, it rebounds, driving the clamping block 4 to slide back to its position in the cavity 5. When assembling a new building railing, there is no need to manually adjust the clamping block 4, improving the convenience during work.

[0026] Refer to Figures 1-3 A handle 15 is fixedly arranged on the bolt 14. The number of handles 15 is two, and the two handles 15 are respectively arranged at the top and bottom of the bolt 14. The arrangement of the handle 15 can make it more convenient to rotate the bolt 14, saving time and effort, and there is no need to specifically use a tool adapted to the bolt 14 for rotation.

[0027] Refer to Figures 1-3The outer surface of the handle 15 is provided with anti-slip particles 16 to increase the friction and prevent slipping, increasing the friction between the hand and the handle 15, preventing the problem of hand slipping during rotation, and making the rotation process more stable and convenient.

[0028] Working principle: When assembling a building railing, place the railing body 3 in the placement groove 13. If the railing body 3 is relatively thin, there will be a certain gap in the placement groove 13. Rotate the handle 15 clockwise to drive the bolt 14 to rotate inward, pushing the clamping block 4 to move towards the middle and clamp the railing body 3. While the cavity 5 moves towards the middle, the sliders 7 at the top and bottom of the cavity 5 slide on the limiting rod 6. The limiting rod 6 plays a certain limiting role to prevent deviation during the sliding process. The connecting rod 9 also slides in the mounting opening 10 to assist the movement of the clamping block 4. During the sliding process, the return spring 8 on one side of the slider 7 is stretched and tightened, which can also play a limiting role to a certain extent. When disassembling the building railing, rotate the handle 15 counterclockwise to remove the handle 15. At this time, due to the elastic force of the return spring 8 itself, it rebounds, driving the clamping block 4 to slide back to its original position in the cavity 5. If the railing body 3 is relatively thick, when placing the railing body 3 in the placement groove 13, only slightly rotate the bolt 14 to clamp and fix it, enhancing a certain stability, having a wider application range, and the operation steps and methods are also simpler and more concise, improving work efficiency.
