The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Example 1

[0034] Combination Figures 1 to 8 As shown, the convenient installation structure of the utility model is schematically shown, which is suitable for a hollow guardrail tube 10. The outer wall surface of the guardrail tube 10 is provided with a mounting slot 11 connected to the interior thereof, and the extension direction of the mounting slot 11 is parallel to the axis of the guardrail tube 10. In the present embodiment, the opening shape of the mounting slot 11 is rectangular, so it has two ends and two sides. When the cross-section of the guardrail tube 10 is circular, the cross-section of the end of the mounting slot 11 is arc-shaped, and the cross-section of the side of the mounting slot 11 is a straight line.

[0035] Combination Figure 1 and Figure 8 As shown, the convenient installation structure includes a mounting frame 20 and a limiting hole 31 arranged on the side and / or end of the mounting slot hole 11, wherein when the limiting hole 31 is arranged on the side of the mounting slot hole 11, the hole axis of the limiting hole 31 is arc-shaped and is concentrically arranged with the cross-section of the end of the mounting slot hole 11; when the limiting hole 31 is arranged at the end of the mounting slot hole 11, the hole axis of the limiting hole 31 is parallel to or inclined to the side of the mounting slot hole 11 (or the axis of the guardrail tube 10).

[0036] Combination Figures 2 to 5 As shown, the mounting frame 20 is located in the mounting slot 11, and a limit pin 21 is slidably provided on the mounting frame 20. When the limit pin 21 is inserted into the limit hole 31, it is used to prevent the mounting frame 20 from being separated from the mounting slot 11. Therefore, after the mounting frame 20 is placed in the mounting slot 11, force is applied to move the limit pin 21 so that it slides relative to the mounting frame 20, and then the limit pin 21 is inserted into the limit hole 31. The limit pin 21 and the limit hole 31 can prevent the mounting frame 20 from being separated from the mounting slot 11, so as to achieve tool-free connection between the mounting frame 20 and the mounting slot 11, which greatly reduces the installation and maintenance time.

[0037] Specifically, when the limiting hole 31 is provided at the side of the mounting slot 11, the hole axis of the limiting hole 31 is in an arc shape and is arranged concentrically with the cross section of the end of the mounting slot 11, and the axis of the limiting pin 21 is also in an arc shape, so that the limiting pin 21 can penetrate the limiting hole 31. When the limiting hole 31 is provided at the end of the mounting slot 11, the hole axis of the limiting hole 31 is parallel to or inclined to the side of the mounting slot 11, and the limiting pin 21 is provided at the end of the mounting frame 20, and the axis of the limiting pin 21 is in a straight line. For example, when the hole axis of the limiting hole 31 is parallel to the axial direction of the guardrail tube 10, the limiting pin 21 is parallel to the axial direction of the guardrail tube 10.

[0038] Example 2

[0039] like Figures 1 to 11The difference between this embodiment and embodiment 1 is that this embodiment is applicable to the limit pin 21 whose axis is linear. Figure 6 and Figure 7 As shown, the mounting frame 20 is provided with a mounting through hole 22 and a limiting component 23, the limiting component 23 is located at the side of the hole opening of the mounting through hole 22 and there is a distance between the two, one end of the limiting pin 21 is slidably inserted into the mounting through hole 22, and the other end of the limiting pin 21 is provided with a rotation limiting arm 211 which is perpendicularly or obliquely arranged thereto, and the rotation limiting arm 211 can abut against the limiting component 23. In actual application, when the end of the limiting pin 21 is arranged opposite to and aligned with the limiting hole 31, the rotation limiting arm 211 can be manually applied to move the rotation limiting arm 211 so that the limiting pin 21 slides relative to the mounting through hole 22 and the limiting pin 21 is inserted into the limiting hole 31. At this time, the mounting through hole 22 is located between the limiting hole 31 and the rotation limiting arm 211. In this process, the rotation limiting arm 211 can be used as a component for the installation and maintenance personnel to apply force to the limiting pin 21. Then, force is applied to pull the rotation-limiting arm 211 to rotate the limit pin 21 around its axis, so that the outer wall surface of the rotation-limiting arm 211 is arranged opposite to one side of the limit component 23. At this time, if the limit pin 21 has a movement tendency to exit the limit hole 31, the rotation-limiting arm 211 will abut against the limit component 23 to prevent the limit pin 21 from exiting the limit hole 31. Therefore, the limit component 23 and the rotation-limiting arm 211 prevent the limit pin 21 from accidentally escaping from the limit hole 31, causing the mounting bracket 20 to escaping from the mounting slot 11.

[0040] Furthermore, if Figure 6 , Figure 7 and Fig.10 As shown, the convenient installation structure also includes an elastic member 212, and the two ends of the elastic member 212 are respectively connected to the mounting frame 20 and the limiting pin 21. When the limiting arm 211 is forced to be moved so that the limiting pin 21 passes through the limiting hole 31, the elastic member 212 is compressed. At this time, the elastic force of the elastic member 212 needs to be overcome. On the contrary, when the limiting arm 211 is forced to be misaligned with the limiting component 23, the elastic force of the elastic member 212 tends to cause the limiting pin 21 to be separated from the limiting hole 31. The purpose of setting the elastic member 212 is that, after the limiting pin 21 passes through the limiting hole 31, the outer wall surface of the limiting arm 211 is arranged opposite to one side of the limiting component 23, and the elastic force of the elastic member 212 will force the limiting arm 211 to abut against the limiting component 23, and the friction between the limiting arm 211 and the limiting component 23 will prevent the limiting pin 21 from rotating accidentally and causing the limiting arm and the limiting component 23 to be misaligned.

[0041] In order to further prevent abnormal misalignment between the limit arm and the limit component 23, an anti-slip part can be provided on the outer wall surface of the limit arm and / or the limit component 23. The anti-slip part is used to increase the friction between the limit arm and the limit component 23. The anti-slip part can be made of rubber, silicone or other materials. In addition, the outer surface of the anti-slip part can also be provided with an anti-slip texture.

[0042] like Figure 7 In order to prevent the limit arm and the limit component 23 from being abnormally misaligned and detached, the limit component 23 includes a first limit section 231 and a second limit section 232 that are perpendicular to each other. The two ends of the first limit section 231 are respectively connected to the end of the second limit section 232 and the mounting frame 20, so that a U-shaped structure is formed between the first limit section 231, the second limit section 232 and the mounting frame 20, and the rotation limiting arm 211 is detachably embedded in the U-shaped structure. The U-shaped structure can completely prevent the limit arm and the limit component 23 from being abnormally detached.

[0043] Example 3

[0044] The difference between this embodiment and embodiment 2 is that the convenient installation structure further includes a mounting block 30 detachably connected to the mounting slot 11, and a limiting hole 31 is provided on the mounting block 30. By adding the limiting hole 31 to the guardrail tube 10 through a detachable mounting block 30, the existing guardrail tube 10 can be minimally modified, so that the application range of the convenient installation structure of the utility model is wider, and there is no need to re-manufacture a new guardrail tube 10, thereby reducing the modification cost.

[0045] Specifically, combined Figure 8 and Fig. 9 As shown, the inner wall surface of the mounting block 30 is provided with two groups of connecting blocks 32, and the number of connecting blocks 32 in each group of connecting blocks 32 is provided. A connecting piece 321 is provided on the connecting block 32 and is arranged parallel to the inner wall surface of the mounting block 30. The cross section of the mounting block 30 is in the shape of an arc to fit the outer wall surface of the guardrail tube 10, so the cross section of the connecting piece 321 is also in the shape of an arc. The connecting pieces 321 on the two connecting blocks 32 extend in two opposite directions respectively, the inner wall surface of the mounting block 30 can be slidably abutted against the outer wall surface of the guardrail tube 10, and the end of the connecting piece 321 can be slidably abutted against the inner wall surface of the guardrail tube 10. Furthermore, the two groups of connecting blocks 32 are respectively connected to the two sides of the mounting slot 11, so the mounting block 30 can slide relative to the mounting slot 11. Before placing the mounting frame 20, firstly, a mounting block 30 is respectively arranged at both ends of the mounting slot 11, and then the mounting frame 20 is placed between the two mounting blocks 30.

[0046] In order to facilitate the installation block 30 to be placed in the installation slot 11, the two sides of the installation slot 11 are provided with a recess 111. Fig.11The openings of the two make way grooves 111 are arranged opposite to each other, and the distance between the groove bottoms of the two make way grooves 111 is greater than the distance between the ends of the connecting pieces 321 on the two connecting blocks 32. At the same time, the distance between the two side edges of the mounting slot hole 11 is less than the distance between the ends of the connecting pieces 321 on the two connecting blocks 32. Therefore, the mounting block 30 can be placed in the mounting slot hole 11 at the position between the two make way grooves 111, and then force is applied to move the mounting block 30 toward one end of the mounting slot hole 11, so that the side edge of the mounting slot hole 11 penetrates into the gap between the inner wall surface of the mounting block 30 and the connecting piece 321. At this time, the mounting block 30 can only slide between the two ends of the mounting slot hole 11.

[0047] In this embodiment, if Figure 6 and Figure 7 The mounting frame 20 is provided with a mounting cavity 24, one end of which is provided with the above-mentioned mounting through hole 22, and the bottom wall of the mounting cavity 24 is provided with a limiting component 23, wherein the first limiting section 231 is fixedly connected to the bottom wall of the mounting cavity 24, and the depth of the mounting cavity 24 is greater than or equal to the length of the rotation limiting arm 211, so that the rotation limiting arm 211 and the limiting pin 21 can be accommodated to prevent the rotation limiting arm 211 from protruding out of the mounting frame 20 and being easily damaged by impact. The opening of the mounting cavity 24 can be covered with a cover plate 40 for decoration, which can not only make the appearance of the mounting frame 20 more beautiful, but also provide protection for the rotation limiting arm 211 and the limiting pin 21.

[0048] Example 4

[0049] In order to solve the same technical problem, the present embodiment discloses a lamp, including a light-emitting device and the convenient installation structure as described above. The light-emitting device can be an LED chip, and the light-emitting device is arranged on a mounting frame 20. Based on the convenient installation structure, the light-emitting device can be installed on the guardrail tube 10 without tools.

[0050] To summarize, the mounting frame 20 can be used to install a light-emitting device to form a lamp, and the limit pin 21 can slide on the mounting frame 20. When the mounting frame 20 is set in the mounting slot 11, the limit pin 21 is moved to make it pass into the limit hole 31 on the side and / or end of the mounting slot 11 to lock the mounting frame 20 and the mounting slot 11. The limit pin 21 and the limit hole 31 can prevent the mounting frame 20 from detaching from the mounting slot 11, so as to achieve tool-free connection between the mounting frame 20 and the mounting slot 11, greatly reducing the installation and maintenance time.

[0051] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
