Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction and maintenance equipment, in particular to a guide rail connecting device and a guide rail connecting structure. Background Art

[0002] During the erection and assembly of power towers and power maintenance, construction workers need to climb ladders or climbing rails. The rails can be equipped with safety devices for connecting to the construction workers. The rail connection structure generally includes two connectors and a connecting section connecting the connectors. Depending on the connection section, it can be divided into a rigid connection structure and a flexible rail connection structure. Since the lengths and angles between the rails are different, the rigid connection structure needs to be customized according to the structure of the tower, resulting in the rigid connection structure being not very versatile and inconvenient to construct. The flexible rail connection structure can be bent and adjusted according to the length and angle between different rails. It is more versatile and more convenient to construct.

[0003] The connectors of existing guide rail connection structures are generally fixedly connected to the guide rails through threaded connections and / or snap connections. Threaded connections are relatively stable, but when both ends are threaded, tightening one end will cause the other end to loosen. Therefore, when connecting two guide rails to the connector of a guide rail connection structure, one end is threaded and the other end is snap-fitted. Snap-fit ​​connections are simple and convenient, but they lack security and stability. Utility Model Content

[0004] The purpose of the utility model is to provide a guide rail connecting device that can solve the above problems.

[0005] In addition, it is also necessary to adopt a guide rail connection structure including the above-mentioned guide rail connection device.

[0011] The U-shaped groove includes an opening section, a rotating section and a snap section connected in sequence, and the end of the opening section away from the rotating section is the opening of the U-shaped groove, and the rotating section extends along the circumference of the fifth fixed end. The snap protrusion slides into the rotating section along the opening section, and finally slides into the snap section. The fourth fixed end rotates counterclockwise relative to the fifth fixed end. At this time, the cylindrical spring is deformed, so that the cylindrical spring drives the snap protrusion of the fourth fixed end to abut against the side wall of the snap section, thereby driving the fifth fixed end, that is, driving the snap sleeve to have a tendency to rotate clockwise relative to the second guide rail.

[0012] In one embodiment, a locking block is provided on the side wall of the locking section close to the opening section, and a locking position is formed between the locking block and the end of the locking section away from the opening section. When the locking protrusion slides into the locking position, the locking block is used to engage with the locking protrusion to prevent the locking protrusion from sliding out of the locking position.

[0014] In one embodiment, the buckle protrusion is semi-cylindrical or semi-elliptical bead-shaped, and when the buckle protrusion slides into the buckle position, the planar side surface of the buckle protrusion faces the clamping block.

[0015] In one embodiment, the opening section and the buckle section are both linear, and are parallel to the axial direction of the fifth fixed end.

[0016] In one embodiment, the fifth fixed end is cylindrical, and the rotating section is arc-shaped.

[0017] In one embodiment, the first fixing end is used to be threadedly connected to the first guide rail, and when the first fixing end is rotated clockwise relative to the first guide rail, the first fixing end is tightened and fixed together with the first guide rail.

[0018] In one embodiment, the first fixing end is used to be inserted into the first guide rail, and the sixth fixing end is used to be inserted into the second guide rail.

That is, when the fourth fixed end of the second connector is snap-connected with the fifth fixed end of the snap-on sleeve, the snap-on sleeve has a tendency to rotate clockwise relative to the second guide rail. Since the sixth fixed end of the snap-on sleeve is used for threaded connection with the second guide rail, and when the sixth fixed end is rotated clockwise relative to the second guide rail, the sixth fixed end is tightened and fixed to the second guide rail. The snap-on sleeve has a tendency to rotate clockwise relative to the second guide rail, which makes the threaded connection between the snap-on sleeve and the second guide rail more secure, preventing the threaded connection from loosening during use.

The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The guide rail connecting device of this embodiment is used to fixedly connect the first guide rail 200 and the second guide rail 300, and includes: a first connecting head 12, a cylindrical spring 14 and a connecting assembly 16.

[0035] The first connector 12 has a first fixed end 122 and a second fixed end 124 opposite to each other. The first fixed end 122 is used for fixed connection with the first guide rail 200 .

[0036] One end of the cylindrical spring 14 is fixedly connected to the second fixed end 124 .

[0037] The connecting assembly 16 includes a second connecting head 162 and a snap sleeve 164, the second connecting head 162 has a third fixed end 1622 and a fourth fixed end 1624 relative to each other, the snap sleeve 164 has a fifth fixed end 1642 and a sixth fixed end 1644 relative to each other, the third fixed end 1622 is fixedly connected to the other end of the cylindrical spring 14, the fourth fixed end 1624 is snap-connected to the fifth fixed end 1642, the sixth fixed end 1644 is used to be threadedly connected to the second guide rail 300, and when the sixth fixed end 1644 is rotated clockwise relative to the second guide rail 300, the sixth fixed end 1644 is tightened and fixed to the second guide rail 300.

[0038] The outer side wall of the fourth fixed end 1624 is provided with a snap protrusion 1626 . The fifth fixed end 1642 is cylindrical. The side wall of the fifth fixed end 1642 is provided with a U-shaped groove 1646 . When the fourth fixed end 1624 is inserted into the fifth fixed end 1642 , the snap protrusion 1626 slides along the U-shaped groove 1646 .

[0039] Combine Figure 4 When the locking protrusion 1626 slides into the rotating section 16464 along the opening section 16462 and finally slides into the locking section 16466, the fourth fixed end 1624 rotates counterclockwise relative to the fifth fixed end 1642. At this time, the cylindrical spring 14 is deformed, so that the cylindrical spring 14 drives the locking protrusion 1626 of the fourth fixed end 1624 to abut against the side wall of the locking section 16466, thereby driving the fifth fixed end 1642, that is, driving the locking sleeve 164 to rotate clockwise relative to the second guide rail 300.

[0040] The implementation of the present invention will have the following beneficial effects:

[0041] The guide rail connecting device of this scheme includes a first connecting head 12, a cylindrical spring 14 and a second connecting head 162 that are fixedly connected in sequence. The first fixed end 122 of the first connecting head 12 is used to be fixedly connected to the first guide rail 200. The fourth fixed end 1624 of the second connecting head 162 is snap-connected with the fifth fixed end 1642 of the snap sleeve 164. The outer wall of the fourth fixed end 1624 is provided with a snap protrusion. The side wall of the fifth fixed end 1642 is provided with a U-shaped groove including an opening section 16462, a rotating section 16464 and a snap section 16466 that are connected in sequence. The fourth fixed end 1624 is inserted into the fifth fixed end 1642. When the snap-on protrusion 1626 slides into the rotating section 16464 along the opening section 16462 and finally slides into the snap-on section 16466 in the end 1642, the fourth fixed end 1624 rotates counterclockwise relative to the fifth fixed end 1642. At this time, the cylindrical spring 14 is deformed, so that the cylindrical spring 14 drives the snap-on protrusion 1626 of the fourth fixed end 1624 to abut against the side wall of the snap-on section 16466, thereby preventing the snap-on protrusion 1626 from detaching from the U-shaped groove 1646, thereby ensuring the safety and stability of the snap-on connection between the second connecting head 162 and the snap-on sleeve 164.

[0042] Furthermore, cylindrical spring 14 drives latching protrusion 1626 of fourth fixing end 1624 into contact with the sidewall of latching section 16466, thereby driving fifth fixing end 1642, and therefore latching sleeve 164, to rotate clockwise relative to second guide rail 300. Specifically, when fourth fixing end 1624 of second connector 162 is latched with fifth fixing end 1642 of latching sleeve 164, latching sleeve 164 tends to rotate clockwise relative to second guide rail 300. Furthermore, since sixth fixing end 1644 of latching sleeve 164 is threadedly coupled to second guide rail 300, when sixth fixing end 1644 rotates clockwise relative to second guide rail 300, sixth fixing end 1644 is tightened and secured to second guide rail 300. The snap sleeve 164 has a tendency to rotate clockwise relative to the second guide rail 300 , which makes the threaded connection between the snap sleeve 164 and the second guide rail 300 more secure, thereby preventing the threaded connection from loosening during use.

[0043] Preferably, combined Figure 4 In this embodiment, a locking block 16468 is provided on the side wall of the locking section 16466 close to the opening section 16462, and a locking position 16469 is formed between the locking block 16468 and the end of the locking section 16466 away from the opening section 16462. When the locking protrusion 1626 slides into the locking position 16469, the locking block 16468 is used to engage with the locking protrusion 1626 to prevent the locking protrusion 1626 from sliding out of the locking position 16469.

[0044] By setting a block 16468 on the side wall of the snap section 16466 close to the opening section 16462, the block 16468 is used to engage with the snap protrusion 1626 to prevent the snap protrusion 1626 from sliding out of the snap position 16469, thereby further improving the safety and stability of the snap connection between the second connecting head 162 and the snap sleeve 164.

[0045] Specifically, combined Figure 4 In this embodiment, the side surface of the clamping block 16468 close to the buckle position 16469 is a steep surface, and the side surface of the clamping block 16468 away from the buckle position 16469 is a smooth surface.

[0046] The side surface of the locking block 16468 close to the locking position 16469 is a steep surface, which can effectively prevent the locking protrusion 1626 from sliding out of the locking position 16469.

[0047] The side surface of the locking block 16468 away from the locking position 16469 is a smooth surface, which allows the locking protrusion 1626 to slide smoothly into the locking position 16469.

[0048] Preferably, in this embodiment, the snap protrusion 1626 is semi-cylindrical or semi-elliptical bead-shaped, and when the snap protrusion 1626 slides into the snap position 16469 , the planar side surface of the snap protrusion 1626 faces the locking block 16468 .

[0049] In other embodiments, the snap protrusion 1626 may also be configured in other shapes as long as it can satisfy the corresponding function.

[0050] Specifically, in this embodiment, the opening section 16462 and the buckle section 16466 are both linear, and the opening section 16462 and the buckle section 16466 are both parallel to the axial direction of the fifth fixing end 1642 .

[0051] Specifically, in this embodiment, the fifth fixed end 1642 is cylindrical, and the rotating section 16464 is arc-shaped.

[0052] Specifically, in this embodiment, the first fixing end 122 is used for threaded connection with the first guide rail 200 , and when the first fixing end 122 is rotated clockwise relative to the first guide rail 200 , the first fixing end 122 and the first guide rail 200 are tightened and fixed together.

[0053] Combined with the above analysis, when the fourth fixed end 1624 of the second connecting head 162 is snap-connected with the fifth fixed end 1642 of the snap sleeve 164, the snap sleeve 164 tends to rotate clockwise relative to the second guide rail 300. At this time, since the second guide rail 300 is fixed, the deformation of the cylindrical spring 14 is transmitted to the first fixed end 122, so that the first fixed end 122 tends to rotate clockwise relative to the first guide rail 200, thereby making the threaded connection between the first fixed end 122 and the first guide rail 200 more secure, avoiding the threaded connection from loosening during use.

[0054] It should be pointed out that, in order to facilitate processing, in this embodiment, when the threaded connection is made, both connected structures are cylindrical.

[0055] Specifically, in this embodiment, the first fixing end 122 is used to be inserted into the first guide rail 200 , and the sixth fixing end 1644 is used to be inserted into the second guide rail 300 .

[0056] Preferably, in this embodiment, the cylindrical spring 14 is formed by winding a steel cable.

[0057] The cylindrical spring 14 made by winding the steel cable has excellent mechanical strength and high elasticity, and can provide a good restoring force after rotational deformation. In addition, the cylindrical spring 14 made by winding the steel cable also has a certain price advantage.

[0058] Combine Figure 3 The present invention also discloses a guide rail connection structure of an embodiment, including a first guide rail 200, a second guide rail 300 and the above-mentioned guide rail connection device, and the guide rail connection device is fixedly connected to the first guide rail 200 and the second guide rail 300 respectively.

[0059] The specific connection structure between the guide rail connecting device and the first guide rail 200 and the second guide rail 300 is as described above and will not be repeated here.

[0060] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
