DETAILED DESCRIPTION

[0029] In order to make the above features and advantages of the present application more apparent, the following specific examples are described in detail below, together with the accompanying drawings, as follows, but the present application is not limited thereto.

[0030] REFERENCE Figures 1 to 8

[0031] An anti-seismic joint system for building electrical pipeline, comprising two mounting assemblies 1, the mounting assembly 1 comprising a box shell 5 with both sides open, the box shell 5 is embedded with a cover plate assembly 6 for connecting wire 12 to pass through at both ends, and the both ends of the box shell 5 can be sealed by the cover plate assembly 6. A winding frame 11 is arranged inside the box shell 6, the winding frame 11 comprising a support 13, a motor 17 is mounted on the inner wall of the top of the support 13 by bolts, and the model of the motor 17 is preferably 42 DC brushless motor. A torque sensor 34 is mounted on the output end of the motor 17 by a flat key, and the torque sensor 34 detects the torque force between the output end of the motor 17 and the winding drum 18. The winding drum 18 is mounted at the bottom end of the torque sensor 34 by bolts, and the connecting wire 12 is wound on the winding drum 18, and the connecting wire 12 can be wound by the winding drum 18.

[0032] In this embodiment, in order to facilitate the disassembly and assembly of the winding frame 11 and the box shell 5, the support 13 has vertical side plates 35 at both ends, and the vertical side plate 35 on one side has a detachable connection structure cooperating with the box shell 5.

[0033] In the embodiment, the detachable connection includes that the bottom and the top of the vertical side plate 35 on one side are both provided with a mounting groove 19, a spring 20 is mounted in the mounting groove 19 through a bolt, the other end of the spring 20 is connected with a plug plate 21, a side outer wall of the plug plate 21 is integrally formed with a push block 22, and the top inner wall and the bottom inner wall of the one side end of the box shell 5 are both correspondingly provided with a clamping groove 36 for the plug plate 21 to be inserted. The plug plate 21 is inserted into the clamping groove 36 under the action of the spring 20, the push block 22 facilitates the movement of the plug plate 21, so that the plug plate 21 is separated from the clamping groove 36, and the restriction between the support 13 and the box shell 5 is released.

[0034] In the embodiment, the top of the support 13 is provided with two wire passing holes 14, and the wire passing holes 14 facilitate the passing of the connecting wire 12 through the support 13. The two side outer walls of the support 13 are both provided with a wire inlet hole 15, and a rubber sleeve 16 is bonded in the wire inlet hole 15. The rubber sleeve 16 helps to prevent the connecting wire 12 from being injured by the edge of the inner wall of the wire inlet hole 15.

[0035] In the embodiment, the cover plate assembly 6 includes a cover plate 23, the cover plate 23 is detachably connected with the box shell 5, the center of the cover plate 23 is connected with a connecting end 2, the other end of the connecting end 2 is inserted with a hose 3, and adjacent two hoses 3 are connected with a straight pipe 4. The design of the straight pipe 4 can make the bottom of the connecting wire 12 installed in the hose 3 not bear a large downward gravity pulling force due to gravity sagging, so as to avoid the problem of reducing the service life of the bottom of the connecting wire 12 due to bearing a large gravity.

[0036] In the embodiment, the bottom and the top of the cover plate 23 are both provided with a mounting groove 25, a plurality of support springs 26 distributed in an equidistant structure are mounted in the mounting groove 25 through bolts, and the top ends of adjacent support springs 26 are connected with a sliding plate 27 slidingly inserted into the mounting groove 25. A plurality of plug blocks 28 are integrally formed on one side outer wall of the sliding plate 27, both side ends of the box shell 5 are provided with a clamping groove 9, and the clamping groove 9 facilitates the cover plate assembly 6 to be located in the box shell 5. The top and the bottom of the clamping groove 9 are both provided with an insertion groove 10, and the plug blocks 28 are inserted into the insertion groove 10. Thus, the plug blocks 28 are inserted into the insertion groove 10 by the support springs 26 pressing against the sliding plate 27, the cover plate assembly 6 is inserted into the box shell 5, and the cover plate assembly 6 and the box shell 5 are fixed.

[0037] In the embodiment, in order to facilitate the disassembly of the cover plate, the upper and lower outer walls of the cover plate are both provided with an avoiding groove 37, and one side of the sliding plate 27 is provided with a push block 38 integrally formed in the avoiding groove. Thus, the sliding plate 27 moves when the push block 38 is pushed, the plug blocks 28 are separated from the insertion groove 10, and the restriction between the cover plate 23 and the box shell 5 is released.

[0038] In this embodiment, the cover plate 23 is provided with a mounting hole 24 in the center of one side outer wall, which corresponds to the wire inlet hole 15. The connecting end 2 is screwed on the mounting hole 24; the hose 3 is screwed with the straight pipe 4.

[0039] In this embodiment, the hose 3 comprises a sleeve 29, which is provided with a folded pipe 30 inside. The folded pipe 30 is made of elastic plastic.

[0040] In this embodiment, the sleeve 29 comprises a base layer 31, which is a rubber tube. The base layer 31 is coated with an inner decoration layer 33 on the inner wall of the side surface. The inner decoration layer 33 is made of insulating paint. The base layer 31 is wrapped with a fiber layer 32 on the outer wall of the side surface. The fiber layer 32 is made of elastic fiber with wear resistance, which can make the sleeve 29 stretchable.

[0041] In this embodiment, the box shell 5 is integrally formed with an ear plate 7 near the bottom on the front and rear side outer walls. The ear plate 7 is cooperated with bolts to fix the installation assembly 1 on the building. The ear plate 7 is provided with through holes 8 on both sides, which are convenient for the bolts to pass through the ear plate 7.

[0042] Working principle: when installing the structure, the installation assembly 1 can be assembled according to the assembly method, and then fixed on the building near the seismic joint through the cooperation of the bolts and the ear plate 7. When an earthquake occurs, the connecting line 12 and the hose 3 near the seismic joint will be pulled. At this time, since the connecting line 12 is installed on the winding drum 18, the winding drum 18 will also be pulled, and a torque force will be generated between the winding drum 18 and the motor 17 output end, so that the torque sensor 34 detects the data. When the detected data is too large, the motor 17 will start, so that the winding drum 18 unwinds the connecting line 12, and the length of the connecting line 12 near the seismic joint becomes longer, so as to prevent the problem that the pipeline near the seismic joint is easy to break due to the short reserved length. At the same time, after the earthquake ends, the motor 17 will start again, so that the winding drum 18 winds the connecting line 12, avoiding that the connecting line 12 is too long to block the seismic joint. At the same time, when the connecting line 12 passes through the seismic joint, the design of the straight pipe 4 can make the bottom of the connecting line 12 installed inside the hose 3 not bear a large downward gravity pulling force due to gravity, avoiding the problem that the bottom of the connecting line 12 bears a large gravity and reduces the service life.
