Description

Technical Field

[0001] This utility model relates to the field of staircase design technology, specifically to an exposed connection device for staircase handrails. Background Technology

[0002] In the field of building construction and decoration, the installation of stair handrails is a common and important task. Stair handrails not only have the function of safety protection, but also play an important decorative role in the overall aesthetics and style of the building. However, in the actual process of installing stair handrails, due to the diversity of stair structures and the complexity of construction site conditions, many challenges are often faced.

[0003] During the installation of traditional stair handrails, the angles and spacing of staircases in different buildings may vary greatly. Conventional connection devices can only adapt to the connection needs of stair handrails with specific angles and spacing. When encountering staircases with special angles or irregular spacing, the installation difficulty will increase significantly, and it may even be necessary to perform additional processing or customization of the stair handrails. This not only increases costs but also extends the installation period.

[0004] In existing technology, traditional stair handrails are typically fixed directly with bolts. However, once the bolts are embedded during installation, adjustments cannot be made after installation. If installation errors or other unforeseen circumstances occur, the entire stair handrail may need to be replaced.

[0005] On the other hand, traditional connection devices have relatively fixed structures and insufficient adjustment flexibility, making it difficult to quickly and conveniently adjust the connection status according to the actual situation, resulting in low installation efficiency and the inability to guarantee the stability and reliability of the connection. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes the following technical solution:

[0007] An exposed connecting device for stair handrails includes a stair handrail and side posts. A sliding post is fixedly installed on one side of the side post. The sliding post has multiple fixing grooves and multiple sliding seats for adjusting the device are slidably installed on the sliding post. A main bolt assembly is provided on one side of the sliding seat. A connecting rod is rotatably installed on the main bolt assembly. An adjusting seat is slidably installed on the outside of the connecting rod. A rotating shaft is rotatably installed on the outside of the adjusting seat. The rotating shaft serves as the shaft connecting the two adjusting seats.

[0008] Furthermore, a limiting strip for limiting is slidably installed on the sliding seat. The limiting strip is L-shaped, with protruding teeth on one side and anti-slip rubber on the other side.

[0009] Furthermore, the protruding teeth on the limiting strip can engage with the fixing groove, thus allowing the limiting strip to restrict the sliding seat onto the sliding column. The limiting strip is fixedly connected to the sliding seat by limiting bolts.

[0010] Furthermore, the connecting rod is provided with multiple positioning holes, and the adjusting seat is threaded with a threaded pin, one end of which is set in the positioning hole of the connecting rod.

[0011] Furthermore, the other end of the threaded pin is disposed outside the adjusting seat, and a rotating handle is provided at the end of the threaded pin disposed outside the adjusting seat.

[0012] The advantages of this utility model compared with the prior art are: (1) By changing the state of the sliding seat, connecting rod and adjusting seat, this device can be adjusted to the maximum extent, and can connect stair handrails with different angles and different spacings. Moreover, the operation of this device is simple and quick, so as to reduce the difficulty of stair handrail installation and improve the efficiency of stair handrail installation; (2) By changing the position of the rotation axis of the rotation center of the connecting rod, this device can change the relative state of the two side columns, thus expanding the scope of application of this device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1 to 6 As shown, an exposed connection device for stair handrails includes a stair handrail 101, which consists of a handrail and multiple posts. During installation, multiple stair handrails 101 are assembled together to form a complete stair handrail. Bolt holes are provided on the posts on both sides of the stair handrail 101. Side posts 102 are provided on the posts of the stair handrail 101. Multiple fixing bolt assemblies 105 are provided on the side posts 102, and the side posts 102 are fixedly connected to the posts on the stair handrail 101 through the fixing bolt assemblies 105. A sliding post 103 is fixedly installed on one side of the side post 102. Multiple fixing grooves are provided on the sliding post 103, and multiple sliding... The sliding seat 201 is used to adjust the device. A limiting strip 202 for limiting is slidably installed on the sliding seat 201. The limiting strip 202 is L-shaped, with protruding teeth on one side and anti-slip rubber on the other side. When the limiting strip 202 contacts the sliding column 103, the protruding teeth on the limiting strip 202 can engage with the fixing groove, thus allowing the limiting strip 202 to restrict the sliding seat 201 to the sliding column 103. The limiting strip 202 is fixedly connected to the sliding seat 201 by a limiting bolt 203. When the user moves the limiting strip 202, they only need to remove the limiting bolt 203 and pull the limiting strip 202.

[0022] like Figures 1 to 6As shown, a main bolt assembly 104 is provided on one side of the sliding seat 201. A connecting rod 205 is rotatably mounted on the main bolt assembly 104. The main bolt assembly 104 not only connects the main bolt assembly 104 and the sliding seat 201, but also serves as a pin. The connecting rod 205 is provided with multiple positioning holes. An adjusting seat 206 is slidably mounted on the outside of the connecting rod 205. A rotating shaft 208 is rotatably mounted on the outside of the adjusting seat 206. The rotating shaft 208 serves as the shaft connecting the two adjusting seats 206. The two adjusting seats 206 are respectively mounted on the two connecting rods 205. Threaded pins 2 are threaded onto the adjusting seats 206. 07. One end of the threaded nail 207 is set in the positioning hole of the connecting rod 205, and the other end of the threaded nail 207 is set outside the adjusting seat 206. The end of the threaded nail 207 set outside the adjusting seat 206 is provided with a rotating handle. After one end of the threaded nail 207 is set inside the connecting rod 205, the position of the adjusting seat 206 will be fixed on the connecting rod 205. When the two adjusting seats 206 of this device are respectively fixed on their respective connecting rods 205, the rotating shaft 208 becomes the rotating axis of the two connecting rods 205. At this time, the two connecting rods 205 form a scissor structure to facilitate the user to adjust the width of the two side columns 102.

[0023] When using this device, it is placed between two stair railings 101 for connection. To connect the two stair railings 101, simply install the side post 102 of this device onto the post of the stair railing 101 using the fixing bolt assembly 105. This allows the device to be installed on one side of the stair railing 101. If the installation position of the next stair railing 101 is not yet determined, first move one end of the two threaded pins 207 of this device out of the positioning hole of the connecting rod 205. This allows the position of the rotating shaft 208 to move on the connecting rod 205. Simultaneously, the user needs to rotate the main bolt assembly 104 to loosen the restriction on the connection between the connecting rod 205 and the sliding seat 201. When loosening the bolt assembly 104, care must be taken not to allow the nut on the main bolt assembly 104 to disengage from the bolt. Loosening it facilitates the user's rotation of the connecting rod 205. After loosening the main bolt assembly 104, the user can also rotate the limiting bolt 203 to loosen the limiting clip 202, thus disengaging the protruding teeth on the limiting clip 202 from the fixing groove. This allows the sliding seat 201 to slide on the sliding column 103. All four sliding seats 201 of this device must undergo this operation. In this state, the device is fully in the debugging phase. Afterwards, install the stair handrail 101 on the other side of the device onto the side column 102. Then, the stair handrail 101 on the other side can be adjusted as needed according to the shape or design requirements of the staircase. In position 1, when installing two stair handrails 101, this device can achieve a configuration where one stair handrail 101 is parallel to the horizontal plane, and the other stair handrail 101 is installed at an angle to the horizontal plane. In this state, it is only necessary to adjust the four sliding seats 201 of this device to slide on the sliding column 103 and change the position of the rotating shaft 208 relative to the connecting rod 205. After adjustment, one end of the threaded nail 207 of this device is inserted into the positioning hole, and then the main bolt assembly 104 is tightened. The main bolt assembly 104 restricts the relative position between the sliding seat 201 and the connecting rod 205, while the protruding teeth on the limiting strip 202 contact the fixing groove, and the position of the limiting strip 202 is restricted by the limiting bolt 203. Thus, this device... The positions of the sliding seat 201, connecting rod 205, and adjusting seat 206 will be fixed, and the device will be in working condition. The sliding seat 201, connecting rod 205, and adjusting seat 206 in working condition will restrict the state between the two stair handrails 101, and the device will serve to connect the two stair handrails 101. This device can also be used in some prefabricated stairs. The sliding seat 201, connecting rod 205, and adjusting seat 206 of this device can be adjusted to working condition in the factory in advance. This will reduce the debugging time during installation and assist the construction personnel in the installation. Moreover, in case of factory customization errors or special situations on site, the construction personnel can actively adjust to achieve the installation purpose.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
