Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a hardware sleeve assembly. Background Technology

[0002] Sleeves act as protective sleeves to protect wires and cables, isolating them from external mechanical damage, especially electromagnetic interference, and preventing communication disruptions. Hardware sleeves are commonly used to protect sensor circuits. Since the length of the wires and cables is unknown during installation, multiple hardware sleeves are typically connected. Currently, this usually involves setting internal and external threads on both sides of the sleeve, forming female and male ends respectively, and connecting two sleeve sections via threads. However, this threaded connection method results in slow installation and disassembly. To improve speed, some designs have created socket ends on both ends of the sleeve, forming male and female socket ends respectively. However, this socketing method can easily cause adjacent sleeves to separate under external force. Therefore, a hardware sleeve assembly that allows for rapid installation and disassembly while preventing separation is needed. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a hardware sleeve assembly that allows for quick splicing and disassembly of two adjacent hardware sleeves, and is not easily separated.

[0004] A hardware sleeve assembly includes: at least two hardware sleeves, with a collar between two adjacent hardware sleeves, one end of each hardware sleeve being connected to the collar and serving as a connecting end; the connecting end has a connecting ring with an outer diameter smaller than the outer diameter of the middle portion of the hardware sleeve, an annular groove at the end of the connecting ring furthest from the port, a connecting groove on the side of the connecting ring, one end of the connecting groove communicating with the side of the annular groove, and the other end of the connecting groove communicating with the outside; the inner side of the collar has protrusions at both ends that mate with the annular groove, and the protrusions can enter the arc groove along the connecting groove.

[0005] Furthermore, the connecting groove is a straight groove, and the length direction of the connecting groove is parallel to the axial direction of the connecting ring.

[0006] Furthermore, the connecting groove is arc-shaped.

[0007] Furthermore, the connecting groove includes a first straight segment and a second straight segment that are aligned with the central axis of the collar. The first straight segment and the second straight segment are located at both ends, and an intermediate segment is provided between the first straight segment and the second straight segment. The intermediate segment is perpendicular to the first straight segment or inclined to the first straight segment or arc-shaped.

[0008] Preferably, the axial lengths of the first straight segment and the second straight segment are both greater than the axial length of the protrusion.

[0009] Furthermore, the first straight segment of the connecting groove is connected to the annular groove, the hardware sleeve is provided with a main concave hole for marking the position of the first straight segment, and the outer surface of the collar is provided with a secondary concave hole for marking the position of the protrusion. When the collar is fitted onto the connecting ring and the main concave hole and the secondary concave hole are opposite to each other, the first straight segment of the connecting groove on the connecting ring is opposite to the corresponding protrusion.

[0010] Preferably, both the main concave hole and the secondary concave hole are semi-circular, and one end of both the main concave hole and the secondary concave hole is connected to the outside. When the collar is fitted onto the connecting ring and the main concave hole and the secondary concave hole are opposite each other, the main concave hole and the secondary concave hole are joined together to form a closed semi-circular hole.

[0011] Furthermore, the thickness of the connecting ring is half the thickness of the middle part of the hardware sleeve, the thickness of the collar is equal to the thickness of the connecting ring, and the outer diameter of the collar is equal to the outer diameter of the middle part of the hardware sleeve.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 4 As shown.

[0026] Example 1: See Figure 1 , Figure 2 A hardware sleeve assembly includes: at least two hardware sleeves 1, a collar 2 is provided between two adjacent hardware sleeves 1, one end of the hardware sleeve 1 is connected to the collar 2 and this end is a connecting end; the connecting end is provided with a connecting ring 13 with an outer diameter smaller than the outer diameter of the middle part of the hardware sleeve 1, an annular groove 12 is provided at the end of the connecting ring 13 away from the port, a connecting groove 17 is provided on the side of the connecting ring 13, one end of the connecting groove 17 communicates with the side of the annular groove 12, and the other end of the connecting groove 17 communicates with the outside, and the inner side of the collar 2 is provided with protrusions 22 at both ends that cooperate with the annular groove 12, and the protrusions 22 can enter the arc groove along the connecting groove 17.

[0027] In this technical solution, when connecting the hardware sleeves 1, one of the two adjacent hardware sleeves 1 is first fixed. For ease of description, this hardware sleeve 1 is defined as the fixed sleeve, and the other is the movable sleeve. Then, the collar 2 is placed over the connecting ring 13 of the fixed sleeve. During the connection, the protrusion 22 at one end of the collar 2 is introduced into the connecting groove 17 and moves along the connecting groove 17, gradually placing the collar 2 over the connecting ring 13. Finally, the protrusion 22 comes out of the connecting groove 17 and enters the annular groove 12. Then, the collar 2 is rotated to make the protrusion 22 misalign with the connecting groove 17. Next, the movable sleeve is connected to the collar 2 to fix the collar 2. Then, the connecting ring 13 of the movable sleeve is inserted into the collar 2. During insertion, the connecting groove 17 on the connecting ring 13 is aligned with the protrusion 22 at the other end of the collar 2, and the protrusion 22 moves along the corresponding connecting groove 17 and enters the annular groove 12 on the movable sleeve. Finally, the movable sleeve or the collar 2 is rotated. During installation, other methods can also be used. When the installation is completed, the protrusions 22 at both ends of the collar 2 enter the annular grooves 12 in the two adjacent hardware sleeves 1, and the protrusions 22 are misaligned with the inner ends of the two connecting grooves 17.

[0028] The collar 2 can quickly connect to two adjacent metal sleeves 1. After connection, the protrusions 22 at both ends of the collar 2 enter the corresponding annular grooves 12, and the inner ends of the protrusions 22 and the connecting grooves 17 are misaligned, thus preventing the metal sleeves 1 from separating. Even if the collar 2 is rotated, the probability of aligning the protrusions 22 with the inner ends of the connecting grooves 17 is very low, thus effectively preventing the metal sleeves 1 from separating.

[0029] See Figure 4 The connecting groove 17 is a straight groove, and the length direction of the connecting groove 17 is parallel to the axial direction of the connecting ring 13.

[0030] By setting the connecting groove 17 as a straight groove, when installing the collar 2, the protrusion 22 can be directly slid from the straight groove into the annular groove 12 very quickly; then the collar 2 rotates, and the protrusion and the straight groove are misaligned. When disassembling, after the protrusion 22 enters the straight groove, it moves in a straight line, which can separate the collar 2 from the connecting ring 13, so it can also be disassembled quickly.

[0031] As a structural variation, the connecting groove 17 is arc-shaped.

[0032] When the connecting ring 13 separates from the collar 2, it is generally in the direction of the axis. To avoid the collar 2 and connecting ring 13 from accidentally causing the protrusion 22 of the collar 2 to align with the connecting groove 17 on the connecting ring 13, and then separating under the push of axial force, this embodiment uses an arc-shaped connecting groove 17. Of course, when the connecting groove 17 is unfolded, it can be an inclined straight line or an arc. The extension direction of the end of the connecting groove 17 forms an angle with the axis, so that the axial force cannot separate the collar 2 and the connecting ring 13; the two adjacent hardware sleeves 1 will also not separate under the influence of axial force. At this time, when separation is required, the collar 2 must first be moved so that the protrusion 22 enters the end opening of the connecting groove 17, and then the collar 2 or hardware sleeve 1 is rotated. At the same time, the collar 2 or hardware sleeve 1 may also need to be moved axially so that the protrusion 22 moves along the connecting groove 17, and finally moves out from the outer port of the connecting groove 17.

[0033] See Figure 2 , Figure 3 The connecting groove 17 includes a first straight segment 16 and a second straight segment 14 that are aligned with the central axis of the collar 2. The first straight segment 16 and the second straight segment 14 are located at both ends. An intermediate segment 15 is provided between the first straight segment 16 and the second straight segment 14. The intermediate segment 15 is perpendicular to the first straight segment 16 or is inclined to the first straight segment 16 or is arc-shaped.

[0034] Preferably, the axial lengths of the first straight segment 16 and the second straight segment 14 are both greater than the axial length of the protrusion 22.

[0035] To facilitate the insertion of the protrusion 22 into the connecting groove 17 while preventing the connecting groove 17 from being axially linear, in this embodiment, the connecting groove 17 is configured as a laterally arranged Z-shape, thus preventing the protrusion 22 of the collar 2 from moving out along the connecting groove 17 under axial force. When the protrusion 22 moves within the middle section 15 of the connecting groove 17, its direction can be perpendicular to the axial direction or inclined. This prevents the protrusion 22 from axially leaving the connecting groove 17. Furthermore, the first straight segment 16 and the second straight segment 14 can be staggered or collinear. When collinear, the middle section 15 is preferably semi-circular or other arc-shaped.

[0036] See Figure 1 , Figure 2 The first straight segment 16 of the connecting groove 17 is connected to the annular groove 12. The hardware sleeve 1 is provided with a main concave hole 11 for marking the position of the first straight segment 16. The outer surface of the collar 2 is provided with a secondary concave hole 21 for marking the position of the protrusion 22. When the collar 2 is fitted onto the connecting ring 13 and the main concave hole 11 and the secondary concave hole 21 are opposite to each other, the first straight segment 16 of the connecting groove 17 on the connecting ring 13 is opposite to the corresponding protrusion 22.

[0037] When the collar 2 separates from the connecting ring 13 of the metal sleeve 1, the collar 2 or the metal sleeve 1 needs to be rotated so that the protrusion 22 moves along the annular groove 12 to the opening of the first straight segment 16 of the connecting groove 17. Therefore, it is necessary to confirm whether the protrusion 22 has moved to the opening. In this embodiment, a main concave hole 11 is provided on the surface of the metal sleeve 1, which is located in the length direction of the first straight segment 16. A secondary concave hole 21 is provided on the outer surface of the collar 2, which is opposite to the protrusion 22. The secondary concave hole 21 is on the outer surface of the collar 2, and the protrusion 22 is located on the inner surface of the collar 2 at the corresponding position. When separation is required, the collar 2 or the metal sleeve 1 is rotated so that the main concave hole 11 is opposite to the secondary concave hole 21. In this way, the protrusion 22 is located at the entrance of the first straight segment 16. Then, the collar 2 or the metal sleeve 1 is moved axially so that the protrusion 22 can enter the connecting groove 17. If the connecting groove 17 is a straight line along the axis, the collar 2 can be directly separated from the hardware sleeve 1; if the connecting groove 17 is of other shapes, the collar 2 can be rotated while applying an axial force to drive the collar 2 to separate; the protrusion 22 then moves along the connecting groove 17 and disengages from the connecting groove 17.

[0038] See Figure 1 , Figure 2 The main concave hole 11 and the secondary concave hole 21 are both semi-circular, and one end of the main concave hole 11 and the secondary concave hole 21 are connected to the outside. When the collar 2 is fitted onto the connecting ring 13 and the main concave hole 11 and the secondary concave hole 21 are opposite each other, the main concave hole 11 and the secondary concave hole 21 are spliced ​​together to form a closed semi-circular hole 3.

[0039] In specific configurations, the main concave hole 11 and the secondary concave hole 21 can also be rectangular holes, joined together to form a closed rectangular hole. Setting the shapes of the main concave hole 11 and the secondary concave hole 21 to be consistent, with one end externally connected, facilitates the alignment and joining of the main concave hole 11 and the secondary concave hole 21, and also facilitates the rotation of the protrusion 22 inside the collar 2 to the entrance of the first straight segment 16 of the connecting groove 17.

[0040] See Figure 3 The thickness of the connecting ring 13 is half the thickness of the middle part of the hardware sleeve 1, the thickness of the collar 2 is equal to the thickness of the connecting ring 13, and the outer diameter of the collar 2 is equal to the outer diameter of the middle part of the hardware sleeve 1.

[0041] To ensure that the metal sleeve assembly has no protruding parts after assembly, in this embodiment, the thickness of the connecting ring 13 is set to be equal to the thickness of the collar 2, and the outer diameter of the collar 2 is equal to the outer diameter of the middle part of the metal sleeve 1. When the collar 2 and the connecting ring 13 are sleeved, the collar 2 and the metal sleeve 1 can be spliced ​​into a new sleeve.

[0042] Preferably, each end of the collar 2 is provided with at least two protrusions 22, and the connecting ring 13 is provided with at least two connecting grooves 17.

[0043] When the hardware sleeve assembly is subjected to axial force, the protrusion 22 and the hardware sleeve 1 form a snap-fit ​​and prevent separation; if only one protrusion 22 is provided, the collar 2 will only be subjected to force in one place; in order to make the collar 2 subjected to force evenly, multiple protrusions 22 need to be provided at each end of the collar 2, at least 2 protrusions 22 should be provided, preferably 3 or 4 protrusions 22, and even more preferably, the protrusions 22 are evenly distributed; correspondingly, the connecting grooves 14 on the connecting ring 13 are provided as 3 or 4.

[0044] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
