Description

Technical Field

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

[0002] The pivot door using a ceiling spring has an automatic closing function, which can improve the privacy of the place of use and reduce the interference of outdoor noise on the place of use. It can also avoid large fluctuations in indoor temperature due to excessive leakage of indoor air flow or excessive infiltration of outdoor air flow.

[0003] Since the pivot door is installed after the wall and floor decoration, and after 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 is 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 with continued use, affecting the operational stability of the hinged door and shortening the service life of the main spring. Utility Model Content

[0057] The eccentric gasket 1142 is provided with an eccentric threaded hole 11420; a gasket mounting groove 11410 is provided in the middle of the mounting plate 1141 extending in the horizontal direction; the gasket mounting groove 11410 is provided with a first through hole 114101; the support plate 134 is provided with a screw fixing hole 1341;

[0058] The mounting plate 1141 is connected to the left side or right side of the sky spring body 111 through the connecting plate 113; the washer fixing screw 1143 passes upward through the eccentric threaded hole 11420, the first through hole 114101, and the screw fixing hole 1341 in sequence, so that the washer fixing screw 1143 is screwed to the support plate 134 and the eccentric washer 1142 respectively, and the mounting plate 1141 is fixed to the support plate 134;

[0060] The first through hole 114101 and the gasket mounting groove 11410 extend in directions opposite to the direction of the shaft deviation respectively; the center point of the mounting plate 1141 is located on the side of the screw fixing hole 1341 opposite to the direction of the shaft deviation, and the distance between the center point of the mounting plate 1141 and the center point of the screw fixing hole 1341 is the same as the shaft deviation distance, and at least one side surface of the eccentric gasket 1142 is against the corresponding groove wall of the gasket mounting groove 11410.

[0061] Figure 1-8The following is a schematic diagram of the pivot door with adjustable offset according to the present invention. The sky spring assembly 11 shown includes an upper pivot shaft 112, a sky spring body 111, and a connecting plate 113. An elastomer and a piston assembly are mounted within the sky spring body 111. The upper end of the upper pivot shaft 112 is drivingly connected to the output end of the piston assembly. A pair of intermeshing bevel gears are mounted on the right side of the sky spring body 111. The upper end of the upper pivot shaft 112 is inserted upward into the sky spring body 111, while the lower end of the upper pivot shaft 112 faces downward toward the top surface of the door body 4 to be installed. Connecting plates 113 are connected to both left and right sides of the bottom of the sky spring body 111. The bottom surfaces of the connecting plates 113 are flush with the bottom surface of the sky spring body 111.

[0062] It should be noted that:

[0063] 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.

[0064] 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.

[0065] The pivot door with adjustable offset of the present invention also includes a sky spring assembly 11 and an installation box 13; the installation box 13 is used to replace the sky spring main body 111 and is installed on the horizontal installation surface above the door body 4 to be installed, so that the offset adjustment of the upper rotating shaft 112 located on the sky spring main body 111 is not restricted by the horizontal installation surface, and the bottom surface of the sky spring main body 111 is connected by the hanging plate 1141, and the sky spring main body 111 is driven to move by moving the hanging plate 1141 to realize the adjustment of the position of the upper rotating shaft 112.

[0066] When in use, a universal gasket is placed in the gasket installation groove 11410, and the outer peripheral surface of the universal gasket is clearance-matched with the gasket installation groove 11410. 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 1143 is passed upward through the through hole of the universal gasket, the first through hole 114101 and the screw fixing hole 1341 in sequence, and the sky spring body 111 with the hanging plates 1141 on both sides is installed on the top surface of the support plate 134 in the installation box 13, and the lower end of the upper rotating shaft 112 in the sky spring body 111 is facing the top of the door body 4 to be installed; after completing the above installation work, rotate the door body 4 to be installed, and confirm whether the central axis of the upper rotating shaft 112 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 upper rotating shaft 112 relative to the central axis of the rotating shaft in the floor spring, and then use the eccentric gasket 1143 to replace the universal gasket, and pass the gasket fixing screw 1143 upward through the eccentric threaded hole 11420, the first through hole 114101 and the screw fixing hole 1341 in sequence. Before tightening the two gasket fixing screws 1143, push the two hanging plates 1141 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 1143 to clamp the hanging plate 1141 between the eccentric gasket 1142 and the support plate 134. In this way, the offset correction of the upper rotating shaft 112 is completed.

[0067] It is worth noting that before tightening the two gasket fixing screws 1143, any side surface of the eccentric gasket 1142 opposite to the direction of the shaft deviation is abutted against the groove wall of the gasket mounting groove 11410, which can prevent the mounting plate 1141 from moving during use, thereby avoiding the upper shaft 112 from being deviated again during use.

[0068] From the above-mentioned correction process of the upper rotating shaft 112, it can be known that the said offset-adjustable rotating shaft door 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 upper rotating shaft 112 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 upper rotating shaft 112, but also avoid the upper rotating shaft 112 from being offset 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.

[0069] Preferably, the eccentric spacer 1142 is hexagonal or octagonal;

[0070] The eccentric direction of the eccentric threaded hole 11420 is opposite to the deviation direction of the rotating shaft; the distance between the central axis of the eccentric threaded hole 11420 and the center point of the eccentric gasket 1142 is the same as the deviation distance of the rotating shaft.

[0071] like Figure 5 and Figure 6 The two embodiments shown, Figure 5 and Figure 6 The two eccentric spacers 1142 are both octagonal.

[0072] Figure 5 The eccentric gasket 1142 is located in a rectangular gasket mounting groove 11410 extending rearward from the middle of the mounting plate 1141. The eccentric threaded hole 11420 of the eccentric gasket 1142 deviates rearward from the center point of the eccentric gasket 1142. The distance between the central axis of the eccentric threaded hole 11420 and the center point of the eccentric gasket 1142 is the same as the deviation distance of the rotating shaft, and the rear side of the eccentric gasket 1142 is abutted against the inner wall of the rear groove wall of the gasket mounting groove 11410. This can correct the deviation of the upper rotating shaft 112 that deviates forward, and prevent the eccentric gasket 1142 from rotating during use.

[0073] Figure 6 The eccentric gasket 1142 is located in the gasket mounting groove 11410 extending from the middle of the mounting plate 1141 to the rear. The eccentric threaded hole 11420 of the eccentric gasket 142 deviates to the left from the center point of the eccentric gasket 1142. The distance between the central axis of the eccentric threaded hole 11420 and the center point of the eccentric gasket 1142 is the same as the deviation distance of the rotating shaft, and the left side of the eccentric gasket 1142 is against the inner wall of the left groove wall of the gasket mounting groove 11410. In this way, the deviation of the rotating shaft 12 deviated to the right can be corrected, and the eccentric gasket 1142 can be prevented from rotating during use.

[0074] According to the description of the above two embodiments, it can be known that in this way, the side of the eccentric gasket 1142 opposite to the deviation direction of the rotating shaft can be pressed against the corresponding groove wall of the gasket mounting groove 11410, so that the eccentric gasket 1142 has good stability, which can effectively prevent the eccentric gasket 1142 from rotating during use, thereby avoiding the upper rotating shaft 112 from being deviated again during use.

[0075] Preferably, the side surface of at least one of the eccentric gaskets 1142 extending along the eccentric direction abuts against the corresponding groove wall of the gasket mounting groove 11410 .

[0076] like Figure 5 and Figure 6 As shown, Figure 5 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 11410; Figure 6The front end face and / or rear end face of the eccentric gasket 1142 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 11410; this can further improve the installation stability of the eccentric gasket 1142 and the mounting plate 1141.

[0077] Furthermore, the installation box 13 also includes an upper cover 131 and a box body 132;

[0078] The installation box 13 is provided with a main body installation through hole 1311;

[0079] The top surface of the upper cover 131 is used to abut against the horizontal installation surface above the door body 4 to be installed;

[0080] The main body installation through hole 1311 passes through the upper cover 131 and the support plate 134 from top to bottom, and the main body installation through hole 1311 is used to accommodate the sky spring main body 111;

[0081] The periphery of the hollow box body 132 abuts against the periphery of the upper cover 131 , and the upper cover 131 and the box body 132 respectively cover the top surface and the outer peripheral surface of the sky spring body 111 , the connecting plate 113 and the hanging component 114 .

[0082] like Figure 2 As shown, during installation, the sky spring body 111 can be placed on the top surface of the support plate 134 through the main body installation through hole 1311, which can improve the installation convenience of the installation box 13 in the sky spring body 111.

[0083] The box body 132 can also hide the sky spring body 111, the connecting plate 113 and the hanging assembly 114 in the installation box 13, preventing the connecting plate 113 and the hanging assembly 114 from being touched, thereby improving the operating safety of the offset-adjustable pivot door and improving the overall aesthetics of the pivot door.

[0084] Furthermore, the sky spring 1 further includes a rotating shaft fixing plate 12;

[0085] The shaft fixing plate 12 includes an upper fixing plate 121 and an upper mounting plate 122; the upper mounting plate 122 is provided with a shaft groove 120;

[0088] like Figure 1-4As shown, the upper rotating shaft 112 is inserted into the rotating shaft groove 120. By observing the gap between the upper rotating shaft 112 and the groove wall of the rotating shaft groove 120, the displacement condition of the upper rotating shaft 112 can be known, and then the displacement of the upper rotating shaft 112 can be corrected by installing the eccentric gasket 1142. After the correction is completed, the upper fixing plate 121 is installed in front of the upper mounting plate 122. The upper fixing plate 121 and the upper mounting plate 122 form an assembly structure that abuts front and back, and close the notch of the rotating shaft groove 120, which can not only improve the installation convenience of the upper rotating shaft 112, but also prevent the upper rotating shaft 112 from swinging.

[0089] Furthermore, the installation box 13 includes a lower cover 133, and the lower cover 133 extending in the left-right direction is located at the bottom of the installation box 13;

[0090] The lower cover 133 includes a left lower cover 1331 and a right lower cover 1332 ; a first groove 13311 is provided at the right end of the left lower cover 1331 , and a second groove 13321 is provided at the left end of the right lower cover 1332 ;

[0091] The right end of the left lower cover 1331 and the left end of the right lower cover 1332 are respectively installed between the sky spring body 111 and the rotating shaft fixing plate 12; the right end of the left lower cover 1331 and the left end of the right lower cover 1332 abut against each other, and the notch of the first groove 13311 and the notch of the second groove 13321 are merged, and the upper rotating shaft 112 is located in the first groove 13311 and the second groove 13321 where the notches are merged;

[0092] The peripheries of the left lower cover 1331 and the right lower cover 1332 abut against the periphery of the box body 132 .

[0093] like Figure 2 As shown, when the verticality of the upper rotating shaft 112 needs to be adjusted, it is only necessary to remove the lower left cover 1331 and the lower right cover 1332 to perform the relevant operations, which has good operational convenience; during use, the covered lower left cover 1331 and the lower right cover 1332 can cover the bottom surface of the sky spring body 111, the bottom surface of the connecting plate 113 and the bottom surface of the hanging assembly 114, so that the sky spring 1 has better concealment and operation safety.

[0094] Furthermore, the ground axis assembly 5 includes a lower fixing plate 51, the lower rotating shaft 52, a rotating shaft seat 53, a lower adjusting screw 54, a rotating shaft sleeve 55 and a guide rod 56;

[0095] The top surface of the lower fixing plate 51 is fixed to the bottom surface of the door body 4 to be installed. The lower fixing plate 51 is provided with a shaft sleeve mounting hole 511, and the hollow shaft sleeve 55 is mounted in the shaft sleeve mounting hole 511;
