Description

Technical Field

[0001] This utility model relates to the technical field of guardrail and handrail connectors, and in particular to a guardrail and handrail connector. Background Technology

[0002] Handrails are widely used in staircases, balconies, roads and other places to play a role in safety protection and guidance. As a key component connecting different parts of the handrail, the performance and ease of installation of the handrail connectors directly affect the stability and effectiveness of the entire handrail system. Existing handrail connectors have many shortcomings. On the one hand, many connectors have a simple structure and are difficult to adapt to complex and diverse installation scenarios. For example, at some stair corners or at the joints of handrails in different directions, common connectors cannot flexibly meet the multi-directional joint requirements, resulting in the need for a lot of on-site processing or complex splicing methods during installation. This not only increases the difficulty and cost of construction, but may also affect the firmness of the connection. On the other hand, some existing connectors are cumbersome to install. Some connectors require a large number of bolts and nuts for fastening, and the distribution and diameter design of the mounting holes are unreasonable, making it difficult to quickly and accurately position and fix them during installation, which consumes a lot of manpower and time. Therefore, it is necessary to design a handrail connector to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a guardrail handrail connector that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A guardrail handrail connector includes a support frame, wherein two support frames are provided. An arc-shaped support plate is fixedly connected to the upper end of each of the two support frames. A docking device is fixedly connected inside each of the two arc-shaped support plates. A connecting device is fixedly connected to the outer side of the two docking devices. Mounting holes are opened at the four corners of the lower end of each of the two support frames. A fixing bolt is threadedly fixed to the outer side of each of the two arc-shaped support plates.

[0005] Preferably, the docking device includes an adjusting movable column. A groove is formed on the rear of the outer surface of the adjusting movable column. A through screw hole is formed in the lower wall of the groove. Multiple positioning points are fixedly connected to the middle of the outer surface of the adjusting movable column. A docking groove is formed at the front end of the adjusting movable column. Six semi-cylinders are fixedly connected to the inner wall of the adjusting movable column. A spline column is inserted into the docking groove. A docking armrest is fixedly connected to the front end of the spline column. A groove is formed on the rear of the outer surface of the docking armrest and the front of the outer surface of the adjusting movable column. A screw hole is formed in the lower wall of the groove. A fixing bolt is threaded into the screw hole. The adjusting movable column is fixedly connected to the front adjusting groove by a bolt with three threads.

[0006] Preferably, the connecting device includes an I-shaped component, with an adjustment groove at the middle of the front end and the middle of the rear end of the I-shaped component, and a circular groove at the front and rear of the upper end of the I-shaped component. The lower wall of the circular groove and the adjustment groove are provided with three screw holes, and three bolts are threaded to the front and rear of the upper end of the I-shaped component.

[0007] Preferably, the semi-cylinders are equidistantly distributed along the inner wall of the adjusting movable column, the outer surface of the spline column is in contact with the inner wall of the mating groove, and the length of the spline column is adapted to the depth of the mating groove.

[0008] Preferably, the positioning points are arranged in a circular array in the middle of the outer surface of the adjustable movable column, and the included angle between two adjacent positioning points is equal.

[0009] Preferably, the two arc-shaped support plates have the same structure and are vertically distributed, and the mounting holes are rectangularly distributed at the four lower corners of the two support frames, and the diameter of the mounting holes is the same.

[0010] Preferably, the I-shaped component has an overall "I"-shaped block structure, and the adjustment groove at the front end and the adjustment groove at the rear end are symmetrically distributed with the central axis of the I-shaped component as the axis of symmetry.

[0011] Preferably, the bolt three passes through the circular groove and is threaded into the screw hole three, and the top diameter of the bolt three is smaller than the diameter of the circular groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, two vertically distributed and structurally identical arc-shaped support plates can be adapted to the docking requirements of guardrails and handrails in different directions. Combined with the multi-angle adjustment capability of the adjustable movable column in the docking device to achieve precise angle positioning, and the fitting structure of the spline column and the docking groove, it can flexibly cope with the connection requirements of complex scenarios such as stair corners and non-standard guardrails. No additional processing of the connectors is required on site. Multi-directional docking can be completed directly through the vertically distributed arc-shaped support plates and the adjustable docking device, overcoming the defect of traditional connectors that cannot adapt to diverse docking scenarios due to their fixed structure.

[0013] 2. In this utility model, the mounting holes with the same diameter and rectangular distribution at the four corners of the lower end of the two support frames can quickly achieve the positioning and installation of the overall structure and the foundation, reducing the alignment time during installation. The fixing bolt on the outer side of the arc-shaped support plate can firmly fix the docking device. The cooperation between the screw hole two and the fixing bolt two in the docking device can firmly connect the docking handrail cylinder and the adjusting movable column. The threaded connection between the bolt three and the screw hole three in the connecting device further enhances the stability of the overall structure. The synergistic effect of multiple fixing structures ensures that the connector is not easy to loosen during long-term use, while simplifying the installation steps and solving the problems of complicated installation and easy loosening caused by unreasonable mounting hole design and single fixing structure of traditional connectors.

A through screw hole 43 is formed in the lower wall of the groove 42. Multiple positioning points 44 are fixedly connected to the middle of the outer surface of the adjusting movable column 41. A docking groove 47 is formed at the front end of the adjusting movable column 41. Six semi-cylinders 48 are fixedly connected to the inner wall of the adjusting movable column 41. A splined column 410 is inserted into the docking groove 47. A docking armrest cylinder 49 is fixedly connected to the front end of the splined column 410. The rear of the outer surface of the docking armrest cylinder 49 is connected to the adjusting movable column 41. The front of the outer surface has a groove 45, and the lower wall of the groove 45 has a screw hole 46. The screw hole 46 is threaded with a fixing bolt 411. The adjusting column 41 is threadedly fixed to the adjusting groove 52 on the front side by a bolt 54. The semi-cylinders 48 are evenly distributed around the inner wall of the adjusting column 41. The outer surface of the spline column 410 fits against the inner wall of the mating groove 47. The length of the spline column 410 matches the depth of the mating groove 47. The positioning points 44 are arranged in a ring array in the middle of the outer surface of the adjusting column 41, and the included angle between two adjacent positioning points 44 is equal.

[0022] Through the above scheme: the groove 42 and the through screw hole 43 on the rear of the outer surface of the adjustable movable column 41 can be fixedly connected with the I-shaped part 51; the positioning points 44 in the middle of the outer surface are arranged in a ring and the adjacent included angles are equal, which facilitates the accurate determination of the installation angle; the six semi-cylinders 48 distributed equidistantly around the inner column wall enhance the structural strength; the docking groove 47 fits the spline column 410 and the length is adapted to ensure stable docking; the groove 45 and the screw hole 46, together with the fixing bolt 411, can firmly connect the docking armrest cylinder 49 and the adjustable movable column 41; the adjustable movable column 41 is fixed in the front adjustment groove 52 by the bolt 54, so that the docking device 4 is installed stably, adjusted conveniently and has strong adaptability.

The front and rear of the upper end of the I-shaped component 51 are both provided with circular grooves 53. The lower groove walls of the circular grooves 53 and the adjustment grooves 52 are both provided with screw holes 55. The front and rear of the upper end of the I-shaped component 51 are both threadedly connected with bolts 54. The I-shaped component 51 is in the shape of an "I" block. The adjustment grooves 52 at the front end and the adjustment grooves 52 at the rear end are symmetrically distributed about the central axis of the I-shaped component 51. The bolts 54 pass through the circular grooves 53 and are threadedly connected to the screw holes 55. The top diameter of the bolts 54 is smaller than the diameter of the circular grooves 53.

[0024] Through the above scheme: the I-shaped component 51, which has an overall "I"-shaped block structure, has adjustment grooves 52 that are symmetrically distributed at the front and rear ends along the central axis, which can be adapted to the installation of two docking devices 4.

Bolt 3 54 passes through the circular groove 53 and is threaded into the screw hole 3 55. The top diameter of bolt 3 54 is smaller than the diameter of the circular groove 53, thereby achieving the fixation and position adjustment of the two docking devices 4 on the connecting device 5. The positioning points 44 on the outer surface of the adjusting movable column 41 are arranged in a ring array with equal included angles between adjacent two points. The adjustment column 41 is used to determine the installation angle of the adjusting column 41. The groove 42 on the rear of the outer surface of the adjusting column 41 and the screw hole 43 penetrating the lower groove wall can be used for additional fixing or connection. The docking armrest cylinder 49 is installed in the docking groove 47 at the front end of the adjusting column 41 by inserting a spline column 410. The outer surface of the spline column 410 fits against the inner groove wall of the docking groove 47 and its length matches the depth of the docking groove 47, ensuring the stability of the docking. Six semi-cylinders 410 are fixedly connected to the inner column wall of the adjusting column 41 and are distributed equidistantly along the circumference. 8 can enhance the structural strength of the adjustable movable column 41. The groove 45 on the rear of the outer surface of the connecting handrail tube 49 and the screw hole 46 on the front of the outer surface of the adjustable movable column 41 are used with the fixing bolt 411 to firmly connect the connecting handrail tube 49 and the adjustable movable column 41, thereby realizing the stable connection and installation of the guardrail. At the same time, by adjusting the position of the adjustable movable column 41 in the adjusting groove 52 and the connection depth between the connecting handrail tube 49 and the adjustable movable column 41, the connection needs of the guardrail in different installation scenarios can be adapted.
