Description

Technical Field

[0001] The invention relates to the field of communication lighting facilities, and in particular to a single-slot guide rail pole and a method for installing pole external equipment. Background Art

[0002] With the increasingly rapid urbanization process in my country, the function of street lamps is not limited to lighting functions. External devices such as cameras, LED lights or billboards are often installed on the pole body according to needs. Conventionally, holes are directly opened on the pole body to fix the installation equipment and external leads are directly connected to the outside of the pole body. As the number of devices installed on the pole body increases, more holes are drilled or welded on the pole body, which seriously affects the structural strength of the pole body. In addition, the cables used for equipment installation are exposed, the cables are prone to aging and affect the appearance of the pole body.

[0003] In summary, there is an urgent need for a technical solution to solve the existing technical problem that a large number of external devices are drilled on the main body of the pole, which easily affects the strength of the main body of the pole. Summary of the invention

DETAILED DESCRIPTION

[0076] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0077] Example 1

[0078] like Figure 1 to Figure 4 The present embodiment shown is a single-slot guide rail pole, comprising a pole body 1, wherein the guide rail 2 is provided with a single slot 2a, wherein the single slot 2a is used for arranging cables and installing equipment connection devices 4, thereby reducing the number of holes drilled on the pole body 1 and solving the technical problem that drilling holes on the pole body 1 to install a large number of external devices easily affects the strength of the pole body 1.

[0079] A plurality of connection holes 1e are provided at relative positions between the guide rail 2 and the side wall of the pole body 1. The guide rail 2 and the pole body 1 are fixed by riveting or bolting through the connection holes 1e, which are used to fix the guide rail 2 on the pole body 1, increase the strength of the guide rail 2, and connect and fix the guide rail 2 to the pole body 1. By installing a large number of external devices on the guide rail 2 instead of the conventional method of directly drilling holes on the pole body 1 to install the external devices, the number of holes drilled on the pole body 1 can be reduced, thereby avoiding affecting the strength of the pole body 1.

[0080] The equipment connection device 4 includes a special-shaped bolt fastener 4a and an external equipment connection member 4b; the external equipment connection member 4a is detachably connected to the single slot 2a via the special-shaped bolt fastener 4a, so as to facilitate the installation and removal of the external equipment connection member 4b.

[0081] The special-shaped bolt fastener 4a includes a special-shaped screw 4a1 and a nut 4a2, wherein the nut 4a2 is adapted to the rod column of the special-shaped screw 4a1, a hook wedge portion 4a3 is provided at one end of the special-shaped screw 4a1, and the hook wedge portion 4a3 matches the inner side wall of the single groove 2a, which is beneficial to improving the stability of the installation of the special-shaped screw 4a1 and the single groove 2a, and a limiting portion 4a4 is also provided on the special-shaped screw 4a1, wherein the limiting portion 4a4 and the hook wedge portion 4a3 are located at one end of the special-shaped screw 4a1 and are arranged at an angle of 90°, and the limiting portion 4a4 includes a limiting block, wherein a screw hole 4a41 is penetrated by the limiting block, and a stud 4a42 is provided in the screw hole 4a41, and the stud 4a42 is threadedly connected with the screw hole 4a41, and the stud 4a42 is screwed by rotating the stud 4a42 along the screw hole 4a41. One end of the single groove 2a abuts against the bottom of the single groove 2a, and the reaction force of the bottom of the single groove 2a on the stud 4a42 can generate a pre-tightening force through the limit block to make the hook wedge part 4a3 abut against the inner wall of the single groove 2a, thereby achieving the purpose of positioning the special-shaped screw 4a1 in the single groove 2a, preventing the special-shaped screw 4a1 from moving and falling along the single groove 2a under the action of gravity, and facilitating the operator to install the external device connector 4b on the special-shaped screw 4a1.

The first contact portion 4a31 contacts the inner wall of the single groove 2a to form a first pressing force, and the second contact portion 4a32 contacts the inner wall of the single groove 2a to form a second pressing force; the normal line of the first pressing force along the contact surface and the normal line of the second pressing force along the contact surface can intersect to form a wedge angle, so that the hook wedge portion 4a3 produces a pressure on the single groove 2a. The clamping force is good, and the stability is good, which can effectively reduce the force shaking of the external device connected to the special-shaped screw 4a1. The hook wedge portion 4a3 is also provided with a profile 4a33, and the profile 4a33 is located between the first contact portion 4a31 and the second contact portion 4a32. When the first contact portion 4a31 and the second contact portion 4a32 are in contact with the inner wall of the single groove 2a at the same time, a gap is formed between the profile 4a33 and the inner wall of the single groove 2a. Under the action of the lateral external force, the hook wedge portion 4a3 of the special-shaped screw 4a1 is the main force-bearing part, and the first contact portion 4a31 The contact portion with the single groove 2a and the contact portion between the second contact portion 4a32 and the single groove 2a are both susceptible to deformation, and a buffer space for elastic deformation of the hook wedge portion 4a3 is formed through the gap between the profile 4a33 and the inner wall of the single groove 2a, thereby forming a pre-tensioning force on the hook wedge portion 4a3 relative to the single groove 2a. Under the action of the pre-tensioning force, the rigidity of the connection between the hook wedge portion 4a3 and the single groove 2a is reduced, thereby preventing the special-shaped screw 4a1 from loosening.
