Description

Technical Field

[0001] The utility model relates to the technical field of rotating shaft doors, in particular to a sky spring kit with adjustable rotating shaft offset. Background Art

[0002] The ceiling springs widely used in pivot doors have the function of automatic door closing, which can improve the convenience of opening and closing doors in the use place, reduce the impact of outdoor noise and temperature on the indoor environment, and reduce the convection between indoor and outdoor air, which may cause excessive fluctuations in room temperature.

[0003] Since the installation of the pivot door occurs after the wall and floor decoration are completed and the floor spring has been installed, when the ceiling spring body is installed, due to the deviation in the size of the installation groove for installing the ceiling spring body, or the deviation in the processing size of the ceiling spring body, the pivot in the ceiling spring body installed in the installation groove becomes offset, that is, the central axis of the pivot in the ceiling spring body and the central axis of the rotating shaft in the floor spring are not on the same vertical line, resulting in the phenomenon commonly known in the industry as the sky and earth axis misalignment.

[0004] Existing techniques correct for shaft misalignment by enlarging the mounting slot and filling the gap between the main spring body and the mounting slot with an object. After a period of operation, the gap between the filling object and the mounting slot wall can wear out, causing the main spring body to shift, further misaligning the shaft. This can also cause the shaft to wear during continued use, affecting the operating stability of the spring and reducing its service life. Utility Model Content

[0043] The mounting assembly 14 includes a mounting plate 141 , a gasket fixing screw 143 and an eccentric gasket 142 ;

[0044] The mounting box 3 is used to be mounted above the door body to be mounted. A support plate 34 extending in the horizontal direction is provided in the mounting box 3. The eccentric gasket 142 is provided with an eccentric threaded hole 1420. A gasket mounting groove 1410 is provided in the middle of the mounting plate 141 extending in the horizontal direction. The gasket mounting groove 1410 is provided with a first through hole 14101. The support plate 34 is provided with a screw fixing hole 341.

[0045] The mounting plate 141 is connected to the left side or right side of the sky spring body 11 through the connecting plate 13; the washer fixing screw 143 passes upward through the eccentric threaded hole 1420, the first through hole 14101, and the screw fixing hole 341 in sequence, so that the washer fixing screw 143 is screwed to the support plate 34 and the eccentric washer 142 respectively, and the mounting plate 141 is fixed to the support plate 34;

[0046] The center point of the mounting plate 141 and the center point of the gasket mounting groove 1410 are located on the same vertical line; the center points of the two mounting plates 141 and the central axis of the rotating shaft 12 are located on the same vertical plane;

[0047] The first through hole 14101 and the gasket mounting groove 1410 extend in directions opposite to the deviation direction of the rotating shaft respectively; the center point of the mounting plate 141 is located on the side of the screw fixing hole 341 opposite to the deviation direction of the rotating shaft, and the distance between the center point of the mounting plate 141 and the center point of the screw fixing hole 341 is the same as the deviation distance of the rotating shaft, and at least one side surface of the eccentric gasket 142 is against the corresponding groove wall of the gasket mounting groove 1410.

[0048] Figure 1-5 The figure shows the installation structure of the adjustable-axis sky spring assembly of the present invention. The sky spring assembly 1 includes a shaft 12, a sky spring body 11, and two connecting plates 13. The spring body 11 houses an elastic body and a piston assembly. The upper end of the shaft 12 extends upward into the sky spring body 11. Connecting plates 13 are connected to the left and right sides of the bottom surface of the sky spring body 11, and the bottom surfaces of the connecting plates 13 are flush with the bottom surface of the sky spring body 11.

[0049] It should be noted that:

[0050] 1. The aforementioned axis offset direction refers to the direction of the offset axis 12 relative to a line perpendicular to the center axis of the floor spring's rotation axis. The aforementioned axis offset distance refers to the distance between a line perpendicular to the center axis of the offset axis 12 and a line perpendicular to the center axis of the floor spring's rotation axis.

[0051] 2. The universal gasket described below is provided with a central through hole, that is, the through hole is located in the center of the universal gasket.

[0052] The sky spring kit with adjustable shaft offset of the present invention also includes an installation box 3 and a hanging assembly 14; the installation box 3 is used to replace the sky spring main body 11 and is installed on the horizontal installation surface above the door body to be installed, so that the offset adjustment of the shaft 12 located on the sky spring main body 11 is not restricted by the horizontal installation surface, and the bottom surface of the sky spring main body 11 is connected by the hanging plate 141, and the sky spring main body 11 is driven to move by moving the hanging plate 141 to achieve the adjustment of the position of the shaft 12.

[0053] When in use, a universal gasket is placed in the gasket installation groove 1410, and the outer peripheral surface of the universal gasket is clearance-matched with the gasket installation groove 1410. The universal gasket is provided with a through hole in the center, that is, the through hole is located in the center of the universal gasket, and the gasket fixing screw 143 is passed upward through the through hole of the universal gasket, the first through hole 14101 and the screw fixing hole 341 in sequence, and the sky spring body 11 with the hanging plates 141 connected on both sides is installed on the top surface of the support plate 34 in the installation box 3, and the lower end of the rotating shaft 12 in the sky spring body 11 is facing the top of the door body to be installed; after completing the above installation work, rotate the door body to be installed, and confirm whether the central axis of the rotating shaft 12 is coaxial with the rotating axis in the floor spring by observing the gap around the door body; if they are coaxial , which means that the installation of the door body is qualified, that is, the installation of the sky spring main body 11 is completed; if misalignment is found, immediately measure and confirm the offset direction and deviation distance of the rotating shaft 12 relative to the central axis of the rotating shaft in the floor spring, and then replace the universal gasket with an eccentric gasket 143, and pass the gasket fixing screw 143 upward through the eccentric threaded hole 1420, the first through hole 14101 and the screw fixing hole 341 in sequence. Before tightening the two gasket fixing screws 143, push the two hanging plates 141 in the direction opposite to the offset direction and move the same distance as the deviation distance, and then tighten the two gasket fixing screws 143 to clamp the hanging plate 141 between the eccentric gasket 142 and the support plate 34. In this way, the deviation correction of the rotating shaft 12 is completed.

[0054] It is worth noting that before tightening the two gasket fixing screws 143, any side surface of the eccentric gasket 142 opposite to the direction of the shaft deviation is abutted against the groove wall of the gasket mounting groove 1410, which can prevent the mounting plate 141 from moving during use, thereby avoiding the shaft 12 from being deviated again during use.

[0055] From the above-mentioned correction process of the rotating shaft 12, it can be known that the ceiling spring kit with adjustable rotating shaft offset of the utility model does not need to open an installation groove during the installation process, nor does it need to correct the offset of the rotating shaft 12 by expanding the installation groove of the ceiling spring body. It has the advantage of convenient operation, which can not only correct the offset of the rotating shaft 12, but also avoid the offset phenomenon of the rotating shaft 12 again, and can improve the installation efficiency of the door body, thereby ensuring the operating stability of the door body after installation and ensuring the service life of the ceiling spring.

[0056] Preferably, the eccentric spacer 142 is hexagonal or octagonal;

[0057] The eccentric direction of the eccentric threaded hole 1420 is opposite to the deviation direction of the rotating shaft; the distance between the central axis of the eccentric threaded hole 1420 and the center point of the eccentric gasket 142 is the same as the deviation distance of the rotating shaft.

[0058] like Figure 4 and Figure 5 The two embodiments shown, Figure 4 and Figure 5 The two eccentric spacers 142 are both octagonal.

[0059] Figure 4 The eccentric gasket 142 is located in a rectangular gasket mounting groove 1410 extending rearward from the middle of the mounting plate 141. The eccentric threaded hole 1420 of the eccentric gasket 142 deviates rearward from the center point of the eccentric gasket 142. The distance between the central axis of the eccentric threaded hole 1420 and the center point of the eccentric gasket 142 is the same as the deviation distance of the rotating shaft, and the rear side of the eccentric gasket 142 is against the inner wall of the rear groove wall of the gasket mounting groove 1410. In this way, the deviation of the rotating shaft 12 deviated toward the front can be corrected, and the eccentric gasket 142 can be prevented from rotating during use.

[0060] Figure 5 The eccentric gasket 142 is located in the gasket mounting groove 1410 extending from the middle of the mounting plate 141 to the rear. The eccentric threaded hole 1420 of the eccentric gasket 142 deviates to the left from the center point of the eccentric gasket 142. The distance between the central axis of the eccentric threaded hole 1420 and the center point of the eccentric gasket 142 is the same as the deviation distance of the rotating shaft, and the left side of the eccentric gasket 142 is against the inner wall of the left groove wall of the gasket mounting groove 1410. In this way, the deviation of the rotating shaft 12 deviated to the right can be corrected, and the eccentric gasket 142 can be prevented from rotating during use.

[0061] According to the description of the above two embodiments, it can be known that in this way, the side of the eccentric gasket 142 opposite to the deviation direction of the rotating shaft can be pressed against the corresponding groove wall of the gasket mounting groove 1410, so that the eccentric gasket 142 has good stability, which can effectively prevent the eccentric gasket 142 from rotating during use, thereby avoiding the deviation phenomenon of the rotating shaft 12 again during use.

[0062] Preferably, a side surface of at least one of the eccentric gaskets 142 extending along the eccentric direction abuts against a corresponding groove wall of the gasket mounting groove 1410 .

[0063] like Figure 4 and Figure 5 As shown, Figure 4 The left side and / or right side of the eccentric gasket 142 abuts against the inner wall of the left groove wall and / or the inner wall of the right groove wall of the gasket installation groove 1410; Figure 5 The front end face and / or rear end face of the eccentric gasket 142 are against the inner wall of the front groove wall and / or the inner wall of the rear groove wall of the gasket mounting groove 1410; this can further improve the installation stability of the eccentric gasket 142 and the mounting plate 141.

[0064] Furthermore, the installation box 3 further includes an upper cover 31;

[0065] The installation box 3 is provided with a main body installation through hole 311;

[0066] The top surface of the upper cover 31 is used to abut against the horizontal installation surface above the door body to be installed;

[0067] The main body installation through hole 311 passes through the upper cover 31 and the support plate 34 from top to bottom, and the main body installation through hole 311 is used to accommodate the sky spring main body 11.

[0068] like Figure 1 As shown, during installation, the sky spring body 11 can be placed on the top surface of the support plate 34 through the main body installation through hole 311, which can improve the installation convenience of the installation box 3 in the sky spring body 11.

[0069] Furthermore, the installation box 3 further includes a box body 32;

[0070] The periphery of the hollow box body 32 is connected to the periphery of the upper cover 31 , and the box body 32 covers the outer circumferences of the sky spring body 11 , the connecting plate 13 and the hanging assembly 14 respectively.

[0071] like Figure 1As shown, such a box body 32 can hide the sky spring main body 11, the connecting plate 13 and the hanging component 14 in the installation box 3, preventing the connecting plate 13 and the hanging component 14 from being touched, thereby improving the operating safety of the sky spring kit with adjustable shaft offset, and also improving the overall aesthetics of the sky spring kit with adjustable shaft offset.

[0072] Furthermore, it also includes a rotating shaft fixing plate 2;

[0073] The shaft fixing plate 2 includes an upper fixing plate 21 and an upper mounting plate 22; the upper mounting plate 22 is provided with a shaft groove 120 extending in the vertical direction;

[0074] The upper mounting plate 22 is used to be fixed to the top of the door body to be installed, and the rear surface of the upper fixing plate 21 abuts against the front surface of the upper mounting plate 22. The upper fixing plate 21 closes the notch of the rotating shaft groove 120. The vertical center axis of the rotating shaft groove 120 is used to align with the center axis of the rotating shaft of the floor spring.

[0075] The rotating shaft 12 is inserted into the rotating shaft groove 120 , and the rotating shaft 12 and the rotating shaft groove 120 are loosely matched.

[0076] like Figure 1-2 As shown, the shaft 12 is inserted into the shaft groove 20 of the mounting plate 22 installed on the top of the door body. By observing the gap between the shaft 12 and the shaft groove 20, the offset condition of the shaft 12 can be known; after the offset correction of the shaft 12 is completed, the upper fixing plate 21 is installed on the front plate surface of the upper mounting plate 22 to close the side notch of the shaft groove 20. The two-piece detachable structure of the shaft fixing plate 2 can improve the convenience of disassembly and assembly when maintaining the shaft 12.

[0077] Furthermore, the installation box 3 further includes a lower cover plate 33;

[0078] The lower cover plate 33 is divided into a left lower cover plate 331 and a right lower cover plate 332 ; a first groove 3311 is provided at the right end of the left lower cover plate 331 , and a second groove 3312 is provided at the left end of the right lower cover plate 332 ;

[0079] The right end of the left lower cover plate 331 and the left end of the right lower cover plate 332 are respectively installed between the sky spring body 11 and the shaft fixing plate 2; the right end of the left lower cover plate 331 and the left end of the right lower cover plate 332 are abutted against each other, and the notch of the first groove 3311 and the notch of the second groove 3312 are combined to form a shaft passage slot, and the shaft 12 is located in the shaft passage slot;

[0080] The left lower cover plate 331 and the right lower cover plate 332 abut against four edges of the box body 32 respectively.

[0081] like Figure 1 As shown, when the rotating shaft 12 needs to be inspected, it is only necessary to remove the left lower cover plate 331 and / or the right lower cover plate 332 for observation.

[0082] Moreover, after removing the rotating shaft fixing plate 2 , the sky spring main body 11 can be removed from the installation box 3 from below, thereby improving the convenience of the maintenance operation of the sky spring main body 11 .

[0083] Furthermore, the mounting plate 141 is further provided with at least two locking screw holes 1411;

[0084] The two locking screw holes 1411 are respectively located at two corners of the mounting plate 141 away from the sky spring body 11 .

[0085] like Figure 3-5 As shown, after correcting the rotating shaft 12, a locking screw hole 1411 can be opened on the support plate 34, and then the mounting plate 141 can be locked to the support plate 34 through the locking screw hole 1411 with a pan head screw or a self-tapping screw, which can prevent the eccentric gasket 142 and the gasket fixing screw 143 from loosening during use.

[0086] In summary, if Figure 1-5 In the embodiment of the utility model shown, the sky spring kit with adjustable shaft offset includes a sky spring assembly 1 and an installation box 3; the installation box 3 is used to replace the sky spring main body 11 and is installed above the door body to be installed, and a gasket installation groove 1410 is opened on the hanging plate 141 connected to the sky spring main body 11, and then the movable hanging plate 141 is supported and fixed in the gasket installation groove 1410 by the eccentric gasket 142, so that the sky spring assembly 1 moves with the hanging plate 141, thereby realizing the correction of the offset of the shaft 12 and avoiding the shaft 12 from being offset again during use; it can not only avoid the wear of the offset shaft 12, but also ensure the operating stability of the door body after installation, and also extend the service life of the sky spring.
