Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit inclinometer equipment, in particular to a magnetic attraction connection structure. Background Art

[0002] Inclinometer is an instrument used to measure the tilt angle or displacement of structures or rocks. It usually includes an inclinometer rod and a cable part. One end of the inclinometer rod is connected to the cable of the cable part through a special connector. When in use, the inclinometer rod is lowered to the depth of the foundation pit under the action of its own weight by laying out the cable part, so as to measure the slope at the depth of the foundation pit.

[0003] In the prior art, the cables of the inclinometer rod and the cable part are usually connected by a radial locking process after insertion, and communication interconnection signal lines are arranged in the cable and the inclinometer rod to timely obtain the falling depth and inclinometer data of the inclinometer rod. However, when the inclinometer rod is screwed into the cable part, the screwing in of the inclinometer rod will cause the signal line inside to be twisted and deformed, thereby affecting the signal transmission performance. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a magnetic connection structure, which not only ensures the stable connection between the inclinometer rod and the cable part, but also avoids the torsional deformation problem of the internal signal line caused by the torsion of the inclinometer rod, thereby solving the problems of low yield and unstable transmission data caused by the existing assembly process.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a magnetic connection structure, including a first connector and a second connector that can be magnetically fixed and communicatively connected, wherein:

[0006] One end of the No. 2 connector is used for magnetic fixation of the No. 1 connector, and the other end is used for connecting cables; an end of the No. 1 connector away from the No. 2 connector is provided with an electric slip ring structure for connecting an inclinometer rod;

[0007] The electric slip ring structure includes a slip ring seat, an electric slip ring, and a pipe sleeve. The slip ring seat is fixedly connected to the No. 1 connector, and the electric slip ring communicatively connected to the slip ring is rotatably arranged at one end of the slip ring seat away from the No. 2 connector; the pipe sleeve is fixedly sleeved on the slip ring seat, and an internal thread channel is arranged therein; the inclinometer rod is threadedly connected in the internal thread channel and is communicatively connected to the electric slip ring.

[0008] The beneficial effects of the magnetic connection structure of the utility model are:

[0009] When in use, connect the cable to the No. 2 connector, connect the signal line of the inclinometer rod to the electric slip ring, and screw the inclinometer rod into the internal thread channel. Since the electric slip ring can rotate relative to the slip ring seat, the signal line inside the inclinometer rod can drive the electric slip ring to rotate synchronously with the inclinometer rod during the process of screwing the inclinometer rod into the internal thread channel, thereby avoiding the torsional deformation of the signal line relative to the inclinometer rod and ensuring the stable transmission of the signal line. Due to the threaded connection between the inclinometer rod and the internal thread channel, the inclinometer rod can be stably connected to the No. 1 connector via the pipe sleeve and the slip ring seat. Then, the stable connection between the inclinometer rod and the cable is ensured by magnetic fixation of the No. 1 connector and the No. 2 connector. In addition, the magnetic fixation method can quickly realize the connection or separation of the cable and the inclinometer rod.

[0010] It should be noted that the electric slip ring structure is an existing technology. The slip ring seat is fixed to the No. 1 connector, and the electric slip ring is fixed to the inclinometer rod. When the electric slip ring rotates with the inclinometer rod, the electric slip ring is always in contact with the slip ring seat and can transmit signals and electrical energy, thereby providing possibility for communication connection between the inclinometer rod and the cable.

[0011] Furthermore, the No. 1 connector includes a No. 1 seat body and a No. 1 circuit board. The No. 1 circuit board is sandwiched between the No. 1 seat body and the slip ring seat, and the No. 1 circuit board is respectively connected to the slip ring seat and the No. 2 connector in communication. Through the communication connection between the No. 2 circuit board, the slip ring seat and the No. 2 connector, the signal transmitted from the inclinometer rod to the electric slip ring structure is transmitted to the No. 2 connector, and then transmitted to the cable connected to the No. 2 connector.

[0012] Furthermore, the No. 2 connector includes a No. 2 seat, a No. 2 circuit board, and a magnetic plate. The No. 2 circuit board is sandwiched between the No. 2 seat and the magnetic plate. The end of the magnetic plate away from the No. 2 circuit board can be magnetically adsorbed in the No. 1 seat, and at least one conductive sheet for conducting the No. 1 circuit board and the No. 2 circuit board is provided through the magnetic plate. The cooperation between the magnetic plate and the No. 1 seat realizes the rapid magnetic fixation of the No. 1 connector and the No. 2 connector, and the provision of the conductive sheet realizes the communication interconnection between the No. 1 connector and the No. 2 connector.

[0013] Furthermore, the No. 2 connector also includes a connecting tube and a fixed shell. One end of the connecting tube facing the No. 1 connector is embedded in the fixed shell and can abut against the pipe sleeve, and the other end extends out of the fixed shell to form a cable channel for the cable to enter; the No. 2 seat body is built into the end of the connecting tube facing the pipe sleeve. The setting of the connecting tube can limit the installation of the No. 2 seat body, and at the same time, the connection part between the No. 2 connector and the cable can be protected. The setting of the fixed shell can protect the connection part between the No. 2 connector and the No. 1 connector.

[0014] Furthermore, the inner wall of the connecting tube is provided with a limiting groove for the second seat body to abut against, and the outer wall is provided with a limiting flange that can abut against the fixed shell. The arrangement of the limiting groove and the limiting flange can limit the assembly position of the connecting tube, the second seat body, and the fixed shell, and at the same time ensure that when the magnetic plate and the first seat body are separated, the second seat body, the connecting tube, and the fixed shell can move synchronously.

[0015] Furthermore, the pipe sleeve includes a first pipe sleeve and a second pipe sleeve that are integrally formed and coaxially arranged, the outer diameter of the first pipe sleeve is adapted to the outer diameter of the fixed shell so that the first pipe sleeve can abut against the fixed shell; the outer diameter of the second pipe sleeve is adapted to the inner diameter of the fixed shell so that the second pipe sleeve can be embedded in the fixed shell.

[0016] Furthermore, the second pipe sleeve can be embedded in the fixed housing and abut against the connecting pipe.

[0017] Furthermore, an abutment boss for limiting the position of the slip ring seat is provided in the pipe sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example

[0028] See attached Figure 1-2 As shown, a magnetic connection structure of the utility model comprises a No. 1 connector 1 and a No. 2 connector 2 which can be magnetically fixed and connected for communication, wherein one end of the No. 2 connector 2 is used for magnetic fixation of the No. 1 connector 1, and the other end is used for connecting cables. The end of the No. 1 connector 1 away from the No. 2 connector 2 is provided with an electric slip ring structure 3 for connecting the inclinometer rod. The electric slip ring structure 3 comprises a slip ring seat 31, an electric slip ring 32, and a pipe sleeve 33. The slip ring seat 31 is fixedly connected to the No. 1 connector 1, and the end thereof away from the No. 2 connector 2 is rotatably provided with an electric slip ring 32 which is connected for communication therewith; the pipe sleeve 33 is fixedly sleeved on the slip ring seat 31, and an internal thread channel is provided therein; the inclinometer rod is threadedly connected in the internal thread channel and is connected for communication with the electric slip ring 32.

[0029] When in use, the cable is connected to the No. 2 connector 2, the signal line of the inclinometer rod is connected to the electric slip ring 32, and the inclinometer rod is screwed into the internal thread channel; in the process of the inclinometer rod being screwed into the internal thread channel, because the electric slip ring 32 can rotate relative to the slip ring seat 31, at this time, the signal line inside the inclinometer rod can drive the electric slip ring 32 to rotate synchronously with the inclinometer rod, thereby avoiding the torsional deformation of the signal line relative to the inclinometer rod, ensuring the stable transmission of the signal line, and because of the threaded connection between the inclinometer rod and the internal thread channel, the inclinometer rod can be stably connected to the No. 1 connector 1 via the pipe sleeve 33 and the slip ring seat 31. Then, the connection between the inclinometer rod and the cable is achieved through the magnetic fixation of the No. 1 connector 1 and the No. 2 connector 2.

[0030] It should be noted that the electric slip ring structure 3 is a prior art, the slip ring seat 31 is fixedly connected to the No. 1 connector 1, and the electric slip ring 32 is fixedly connected to the inclinometer rod; when the electric slip ring 32 rotates with the inclinometer rod, the electric slip ring 32 is always in contact with the slip ring seat 31, and can transmit signals and electrical energy, thereby providing possibility for communication connection between the inclinometer rod and the cable.

[0031] For details, see the attached Figure 1-2As shown, the No. 1 connector 1 includes a No. 1 seat body 11 and a No. 1 circuit board 12. The No. 1 circuit board 12 is sandwiched between the No. 1 seat body 11 and the slip ring seat 31, and the slip ring seat 31 is fixed to the No. 1 seat body 11. The No. 1 circuit board 12 is respectively connected to the slip ring seat 31 and the No. 2 connector 2. The No. 2 connector 2 includes a No. 2 seat body 21, a No. 2 circuit board 22, and a magnetic plate 23. The No. 2 circuit board 22 is sandwiched between the No. 2 seat body 21 and the magnetic plate 23. The end of the magnetic plate 23 away from the No. 2 circuit board 22 can be magnetically adsorbed in the No. 1 seat body 11, and at least one conductive sheet 231 for conducting the No. 1 circuit board 12 and the No. 2 circuit board 22 is provided through the magnetic plate 23.

[0032] The magnetic attraction of the magnetic plate 23 and the No. 1 seat body 11 realizes the quick connection of the No. 1 connector 1 and the No. 2 connector 2, thereby improving the assembly efficiency of the cable and the inclinometer rod; and the communication interconnection between the No. 1 circuit board 12 and the No. 2 circuit board 22 is realized by the setting of the conductive sheet 231. It should be noted that when the magnetic plate 23 is separated from the No. 1 seat body 11, the conductive sheet 231 is still in a connected state with the No. 2 circuit board 22, and is in a disconnected state with the No. 1 circuit board 12.

[0033] In some embodiments, the second connector 2 also includes a connecting tube 24 sleeved on the second seat body 21, one end of the connecting tube 24 abuts on the pipe sleeve 33, and the other end forms a cable channel for the cable to enter. One end of the cable can be inserted into the cable channel and communicated with the second circuit board 22. Furthermore, a limiting groove 241 for the second seat body 21 to abut is provided on the inner wall of one end of the connecting tube 24 facing the first connector 1. The setting of the limiting groove 241 can limit the installation position of the second seat body 21, thereby ensuring the stability of the assembly position of the connecting tube 24 and the second seat body 21.

[0034] In some embodiments, the No. 2 connector 2 also includes a fixed shell 25, and the connecting pipe 24 and the pipe sleeve 33 are respectively embedded into the fixed shell 25 from both ends of the fixed shell 25 to limit the connection parts of the No. 1 connector 1 and the No. 2 connector 2 to the fixed shell 25, thereby playing a protective role.

[0035] Furthermore, in order to ensure that when the No. 1 connector 1 and the No. 2 connector 2 are separated, the fixed housing 25 can move synchronously with the connecting pipe. Figure 2-3 As shown, a limiting flange 242 is provided on the outer wall of the connecting tube 24, and a shell boss 251 matching the limiting flange 242 is provided on the inner wall of the fixed shell 25. When the connecting tube 24 is assembled on the fixed shell 25, the limiting flange 242 can abut against the shell boss 251. When the connecting tube 24 is pulled to move away from the first connector 1, the limiting flange 242 can drive the shell boss 251 to move synchronously, thereby driving the fixed shell 25 to move synchronously with the connecting tube 24.

[0036] In some embodiments, see Appendix Figure 2 , 4 As shown, the pipe sleeve 33 includes a first pipe sleeve 331 and a second pipe sleeve 332 that are integrally formed and coaxially arranged. The outer diameter of the first pipe sleeve 331 is adapted to the outer diameter of the fixed shell 25 so that the first pipe sleeve 331 can abut against the fixed shell 25; the outer diameter of the second pipe sleeve 332 is adapted to the inner diameter of the fixed shell 25 so that the second pipe sleeve 232 can be embedded in the fixed shell 25 and abut against the connecting pipe 24.
