Description

Technical Field

[0001] This utility model relates to the field of truss sleeve technology, and in particular to a truss rotating sleeve. Background Technology

[0002] Truss sleeves are important connecting components used in truss structures to connect different truss members together to form a stable truss structure. They are widely used in many fields such as construction, bridges, machinery manufacturing, and aerospace.

[0003] In daily work, it has been found that most existing truss sleeves are fixed. During installation, if the holes on the sleeve do not align with the holes of the corresponding connecting parts, the construction workers have to adjust the entire truss. This operation is quite troublesome. Moreover, during installation, special accessories need to be found to connect the sleeve to other components, which undoubtedly increases the complexity of construction. Furthermore, these special accessories need to be carefully stored during subsequent disassembly, as they are easily lost if not handled carefully, causing inconvenience in overall use. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the fixed type is inconvenient to rotate and adjust, and also requires the search for accessories for connection, resulting in inconvenience in overall use. Therefore, a truss rotating sleeve is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a truss rotating sleeve, including an upper sleeve and a lower sleeve below the upper sleeve. The lower sleeve has a through hole on its surface. An auxiliary device is provided between the upper and lower sleeves. The auxiliary device includes a rotating head fixedly connected to the surface of the lower sleeve. The rotating head is rotatably connected to the inner wall of the upper sleeve. Two rotating seats are fixedly connected to the surface of the lower sleeve. A rotating shaft is rotatably connected to the inner wall of the rotating seat. A rotating block is fixedly connected to the surface of the rotating shaft. Two threaded seats are fixedly connected to the surface of the rotating block. A positioning bolt is threadedly connected to the inner wall of the threaded seat. A positioning part is provided between the rotating block and the rotating seat. Through the above components, when the lower sleeve is connected to the connector, the rotating head can drive the lower sleeve to rotate. When the through hole on the rotating head is quickly aligned with the connecting hole on the connector, the positioning bolt is then rotated. The positioning bolt can be inserted into the through hole and the connecting hole on the surface of the rotating head and the connector in sequence, without the need to find installation accessories, thus achieving rapid assembly.

[0006] Preferably, a nut is fixedly connected to the surface of the positioning bolt. The nut is located between two threaded seats. Through the above-mentioned components, the positioning bolt can be rotated by the nut, and the nut, together with the two threaded seats, can play a positioning role.

[0007] Preferably, the positioning part includes a plug that is slidably connected to the inner wall of the rotating block, and the inner wall of the rotating seat has a socket. The plug is inserted into the inner wall of the socket. Through the above components, the plug can be inserted into the socket on the surface of the rotating seat, thereby limiting the rotation of the rotating block into the rotating seat and facilitating storage.

[0008] Preferably, a spring is fixedly connected to the side of the plug corresponding to the inner wall of the rotating block. Through the above-mentioned components, the spring can control the plug to reset, ensuring the stability of the plug.

[0009] Preferably, a second spring is sleeved on the surface of the rotating shaft, and the two ends of the second spring are fixedly connected to the inner walls of the rotating block and the rotating seat, respectively. Through the above-mentioned components, the second spring can drive the rotating shaft and the rotating seat to unfold quickly.

[0010] Preferably, the inner wall of the lower sleeve is provided with a replacement device. The replacement device includes an inner sleeve located in the inner wall of the lower sleeve. An insert block is fixedly connected to the surface of the inner sleeve. The insert block is inserted into the inner wall of the lower sleeve. A magnetic ring one is fixedly connected to the inner wall of the insert block. A magnetic ring two is fixedly connected to the inner wall of the lower sleeve. The magnetic ring one and magnetic ring two are magnetically connected. Through the above components, the inner sleeve can be installed by the cooperation of the insert block, magnetic ring one, and magnetic ring two. The inner sleeve can be easily replaced after it is damaged, ensuring the stability of the overall connection.

[0011] Preferably, the insert is arranged in a regular hexagonal shape.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an auxiliary device, the rotating head drives the lower sleeve to rotate, which can quickly align the through hole on the surface of the lower sleeve with the connecting hole on the connector head. This reduces the tedious process of manually adjusting the position in the traditional connection method. With the cooperation of the rotating seat, rotating block and positioning bolt, it can be quickly assembled without the need to find parts for connection, reducing the phenomenon of lost parts, greatly improving the speed and convenience of assembly, and saving assembly time. Especially in large-scale truss assembly projects, it can significantly speed up the overall construction progress.

[0014] 2. In this utility model, by setting a positioning part, when the rotating block rotates into the rotating seat, the spring, plug and socket cooperate to position the rotating block.

[0015] 3. By setting up a replacement device, construction personnel can easily disassemble and replace the inner sleeve in the event of long-term use or accidental damage, without having to carry out complicated disassembly and reassembly of the entire sleeve structure. This saves time and ensures the stability and reliability of the entire truss structure. Attached Figure Description

Detailed Implementation

[0023] Please see Figures 1-5 This utility model provides a technical solution: a truss rotating sleeve, including an upper sleeve 1, a lower sleeve 2 below the upper sleeve 1, a through hole on the surface of the lower sleeve 2, and an auxiliary device 3 between the upper sleeve 1 and the lower sleeve 2.

[0024] Specifically, the auxiliary device 3 includes a rotating head 31 fixedly connected to the surface of the lower sleeve 2, the rotating head 31 being rotatably connected to the inner wall of the upper sleeve 1, two rotating seats 32 fixedly connected to the surface of the lower sleeve 2, a rotating shaft 34 rotatably connected to the inner wall of the rotating seat 32, a rotating block 33 fixedly connected to the surface of the rotating shaft 34, two threaded seats 35 fixedly connected to the surface of the rotating block 33, a positioning bolt 38 threadedly connected to the inner wall of the threaded seat 35, and a positioning part 37 provided between the rotating block 33 and the rotating seat 32.

[0025] In this implementation scheme: when the lower sleeve 2 is connected to the connector, the lower sleeve 2 can be rotated by the rotating head 31. When the through hole on the rotating head 31 is quickly aligned with the connecting hole on the connector, the positioning bolt 38 is then rotated. The positioning bolt 38 can be inserted into the through hole and connecting hole on the surface of the rotating head 31 and the connector in sequence, without the need to find installation accessories, thus achieving rapid assembly.

[0026] Specifically, a nut 36 is fixedly connected to the surface of the positioning bolt 38. The nut 36 is located between two threaded seats 35. The positioning bolt 38 can be rotated by the nut 36. At the same time, the nut 36, together with the two threaded seats 35, can play a positioning role.

[0027] Specifically, the positioning part 37 includes a plug 372 that is slidably connected to the inner wall of the rotating block 33, and the inner wall of the rotating seat 32 is provided with a socket 371, and the plug 372 is inserted into the inner wall of the socket 371.

[0028] In this embodiment, the plug 372 can be inserted into the socket 371 on the surface of the rotating base 32 to limit the rotation block 33 that has rotated into the rotating base 32, making it easy to store.

[0029] Specifically, a spring 373 is fixedly connected to the side of the plug 372 corresponding to the inner wall of the rotating block 33.

[0030] In this implementation scheme: Spring 373 can control the plug 372 to reset, ensuring the stability of the plug 372.

[0031] Specifically, a second spring 39 is fitted on the surface of the rotating shaft 34. The two ends of the second spring 39 are fixedly connected to the inner walls of the rotating block 33 and the rotating seat 32, respectively. The second spring 39 can drive the rotating shaft 34 and the rotating seat 32 to unfold quickly.

[0032] Specifically, the inner wall of the lower sleeve 2 is provided with a replacement device 4. The replacement device 4 includes an inner sleeve 41 located in the inner wall of the lower sleeve 2. An insert block 42 is fixedly connected to the surface of the inner sleeve 41. The insert block 42 is inserted into the inner wall of the lower sleeve 2. A magnetic ring 43 is fixedly connected to the inner wall of the insert block 42. A magnetic ring 44 is fixedly connected to the inner wall of the lower sleeve 2. The magnetic ring 43 and the magnetic ring 44 are magnetically connected.

[0033] In this implementation scheme: the inner sleeve 41 can be installed by the cooperation of the insert block 42, magnetic ring 43 and magnetic ring 44. The inner sleeve 41 can be easily replaced if it is damaged, ensuring the stability of the overall connection.

[0034] Specifically, the insert 42 is arranged in a regular hexagonal shape.

[0035] Working principle: During installation, the lower sleeve 2 on the truss can be fitted onto the connector head. Then, the rotating head 31 drives the lower sleeve 2 to rotate within the upper sleeve 1, ensuring that the through hole on the surface of the lower sleeve 2 is aligned with the connection hole on the connector head. Then, the plug 372 is pushed, and the spring 373 is stressed. When the plug 372 is removed from the insertion hole 371 on the surface of the rotating seat 32, the spring 39 releases its elasticity, driving the rotating block 33 and the rotating shaft 34 to rotate, causing the positioning bolt 38 to align with the through hole on the surface of the lower sleeve 2. Then, the nut 36 is rotated, and the threaded nut drives the positioning bolt 38 to rotate within the threaded seat 35, allowing the positioning bolt 38 to insert into the through hole on the surface of the lower sleeve 2 and connect with the connection hole in the subsequent connector head, achieving rapid assembly. When the inner sleeve 41 is damaged, it can be removed from the lower sleeve 2 for replacement, ensuring the stability of the connection.
