Description

Technical Field

[0001] The invention relates to a revolving door, in particular to a revolving door with an adjustable top axis. Background Art

[0002] A revolving door consists of a door frame and a door body, with the door body pivotally connected to the door frame via a central pivot and a ground pivot, respectively. For example, a central pivot door has central pivots, allowing the door body to rotate 360 degrees around its central axis.

[0003] For example, the patent publication number CN102011540A discloses a central axis swing-opening fireproof isolation door and its application. The door axis of the swing-opening door is set in the middle part of the door leaf width direction, and this door is used as a fireproof isolation door or in public places with large and frequent traffic.

[0004] The door clamp of an existing revolving door usually includes a circumferential axis assembly for being fixedly installed with the top of the door frame and an upper clamp for being fixedly installed with the top edge of the door. The circumferential axis assembly and the upper clamp are installed by cooperating with the axis of the circumferential axis assembly and the axis hole in the upper clamp to realize the rotation of the upper clamp along with the circumferential axis assembly, thereby realizing the opening and closing of the door relative to the door frame. However, when the door clamp is not installed properly, resulting in a large gap between the top edge of the door and the door frame, and when the door falls during long-term use, there is a risk that the axis will be disengaged from the axis hole, causing the entire door to fall over and cause injury accidents.

[0005] Existing methods limit the shaft from disengaging from the shaft hole by adjusting the shaft of the shaft assembly to move up and down. For example, the patent publication number CN214303389U discloses a door clamp and a door using the same, comprising a shaft assembly for fixing and embedding in the top of a door frame and an upper clamp for fixing and mounting with the top edge of the door. The shaft assembly comprises a base and a shaft provided on the base, and an adjustment mechanism located on the base for adjusting the axial movement of the shaft. An shaft hole is formed in the upper clamp to cooperate with the shaft. The adjustment mechanism comprises an adjustment ball head fixed to the base and spaced apart from the shaft, a support member located between the shaft and the adjustment ball head, and an adjustment member. The first end of the adjustment member is connected to the shaft, and the second end is rotatably connected to the adjustment ball head. The area of the adjustment member near the adjustment ball head is rotatably connected to the support member. By adjusting the adjustment ball head to move up and down, the adjustment member drives the shaft to move axially.

[0006] For another example, a rotating hidden door with the announcement number CN211038256U includes a door body. At the bottom of one end of the door body, there is a floor hinge, and at the top of one side of the door body, there is a ceiling hinge. A floor hinge mounting plate is provided at the bottom of the floor hinge, and a lower plate is provided at the bottom of the floor hinge. A ceiling hinge mounting plate is provided at the top of the ceiling hinge, and an upper plate is provided at the top of the ceiling hinge. Shaft bodies are provided inside both the floor hinge and the ceiling hinge. The floor hinge and the ceiling hinge are inlaid inside the door body. The floor hinge mounting plate and the ceiling hinge mounting plate are both fixedly connected to the door body by screws. The ceiling hinge can be telescopically adjusted, and the ceiling hinge is inlaid inside the door body to make its structure more beautiful.

[0007] The problems existing in the above-mentioned comparative document are as follows: 1. The shaft core of the ceiling hinge can only be telescopically adjusted up and down and cannot be moved left and right. If it cannot be moved left and right, the accuracy requirement for the docking of the shaft core of the ceiling hinge and the shaft hole during the installation of the door body is very high, and the overall horizontal adjustment of the door frame and the door body is also required to be very high, resulting in time-consuming and laborious installation and increasing the installation difficulty; 2. The above-mentioned adjusting member rotates around the supporting member to make one end tilt up or down to adjust the lifting of the shaft core of the ceiling hinge. Since one end of the adjusting member is inserted into the shaft core, after the adjustment is completed, there is still a certain space for the shaft core of the ceiling hinge to move up and down, which is likely to cause the problem of the shaft core breaking away from the shaft hole; 3. The structure of the above-mentioned ceiling hinge makes the electric control integrated circuit of the door need to be wired from the outside, which is relatively unsightly, and the wires are easily touched and damaged when arranged outside the door body. Summary of the Invention

[0008] Based on the deficiencies that the shaft core of the ceiling hinge of the above-mentioned revolving door can only be telescopically adjusted up and down and cannot be moved left and right, which is not convenient for installing the door body of the revolving door onto the door frame, and the shaft core is prone to move up and down, and the structure of the ceiling hinge is not convenient for wiring, resulting in the revolving door being unsightly, etc., the present invention provides a revolving door with an adjustable shaft core of the ceiling hinge.

The first adjustment mechanism is used to drive the first-stage adjustment seat and the second-stage adjustment seat to move relatively in the X-axis direction. The second adjustment mechanism is used to drive the first-stage adjustment seat and the second-stage adjustment seat to move synchronously in the X-axis direction. When the first-stage adjustment seat and the second-stage adjustment seat move relatively, the core is driven to move up and down. When the first-stage adjustment seat and the second-stage adjustment seat move synchronously, the core is driven to move left and right. The up and down movement and the left and right movement of the core are independently adjusted by the first adjustment mechanism and the second adjustment mechanism respectively. The upper mounting plate is provided with a shaft hole matching the core, and the core is inserted into the shaft hole to connect the top of the door body to the top of the door frame.

The top of the door body 1 is connected to the door frame 2 through the ceiling hinge 5, and the bottom of the door body 1 is connected to the door frame 2 through the floor hinge 3. The door body 1 is connected inside the door frame 2 and can rotate relative to the door frame 2 to open or close. The floor hinge 3 is the same as the floor hinge of the existing revolving doors in the market, and reference can be made to the floor shaft and the lower plate in the patent CN211038256U.

[0038] Figures 1 - 4 Preferably, as shown, the ceiling hinge 5 and the floor hinge 3 are respectively arranged in the middle of the top and bottom of the door body 1. When the door body 1 rotates to open, aisles for people to walk are formed between both sides of the door body 1 and the door frame 2. This structure makes it convenient for pedestrians to pass through the revolving door.

[0039] Figure 3 , Figure 5 As shown, the ceiling hinge 5 includes a ceiling shaft assembly 11 embedded in the top of the door body 1 and an upper mounting plate 6 fixed to the top of the door frame 2.

[0040] The upper mounting plate 6 is provided with screw holes, and the upper mounting plate 6 is fixedly connected to the top of the door frame 2 through screws.

[0041] The upper mounting plate 6 is provided with a shaft hole 7 that cooperates with the sky shaft assembly 11.

[0042] The top of the door body 1 is provided with a mounting groove 12, and the sky shaft assembly 11 is embedded and installed in the mounting groove 12, realizing the concealed installation of the sky shaft assembly 11 and improving the aesthetics.

[0043] Figures 5 - 7 As shown, the sky shaft assembly 11 includes a mounting base 13 fixed to the door body 1, a first-level adjusting base 16, a second-level adjusting base 15, a shaft core 8, a first adjusting mechanism, and a second adjusting mechanism.

[0044] The mounting base 13 is provided with screw holes, and the mounting base 13 is fixedly installed on the top of the door body 1 by screws.

[0045] The first-level adjusting base 16, the second-level adjusting base 15, the shaft core 8, the first adjusting mechanism, and the second adjusting mechanism are all arranged on the mounting base 13.

[0046] The first-level adjusting base 16 and the second-level adjusting base 15 are arranged on the mounting base 13 and can move left and right in the X-axis direction relative to the mounting base 13. The first-level adjusting base 16 is provided with a first limiting slot hole 25 for limiting the movement of the shaft core 8 in the Z-axis direction. The shaft core 8 is limited on the first-level adjusting base 16 and can move in the Z-axis direction relative to the first-level adjusting base 16 along the first limiting slot hole 25. The second-level adjusting base 15 is provided with a second limiting slot hole 21 for limiting the movement of the shaft core 8 in the X-axis and Z-axis directions. The shaft core 8 is limited on the second-level adjusting base 15 and can move in the X-axis and Z-axis directions relative to the second-level adjusting base 15 along the second limiting slot hole 21. The shaft core 8 is limited on the first-level adjusting base 16 and the second-level adjusting base 15 and can move up and down in the Z-axis direction and left and right in the X-axis direction relative to the mounting base 13.

[0047] The first adjusting mechanism is used to drive the first-level adjusting base 16 and the second-level adjusting base 15 to move relatively in the X-axis direction, and the second adjusting mechanism is used to drive the first-level adjusting base 16 and the second-level adjusting base 15 to move synchronously in the X-axis direction. When the first-level adjusting base 16 and the second-level adjusting base 15 move relatively, the shaft core 8 is pushed to move up and down in the Z-axis direction through the cooperation of the first limiting slot hole 25 and the second limiting slot hole 21. When the first-level adjusting base 16 and the second-level adjusting base 15 move together as a whole, the shaft core 8 is pushed to move left and right in the X-axis direction through the first limiting slot hole 25 and the second limiting slot hole 21, realizing the up and down and left and right movement adjustment of the shaft core 8. The up and down movement and left and right movement of the shaft core 8 are independently adjusted by the first adjusting mechanism and the second adjusting mechanism respectively.

[0048] The above-mentioned shaft core 8 is limited on the first-stage adjusting seat 16 and the second-stage adjusting seat 15 by the first limiting slot hole 25 and the second limiting slot hole 21 at the same time, and the up-and-down movement or left-and-right movement of the shaft core 8 is driven by the relative movement or synchronous movement of the first limiting slot hole 25 and the second limiting slot hole 21. The shaft core 8 is limited by the cooperation of the first limiting slot hole 25 and the second limiting slot hole 21. When the first adjusting mechanism and the second adjusting mechanism are not adjusted, the first-stage adjusting seat 16 and the second-stage adjusting seat 15 are relatively fixed to the mounting seat 13. The cooperation of the first limiting slot hole 25 and the second limiting slot hole 21 can play a role in restricting the movement of the shaft core 8, better restricting the up-and-down movement of the shaft core 8 and making the shaft core 8 more stable during use.

[0049] The shaft core 8 is inserted into the shaft hole 7 on the upper mounting plate 6 above, and the top of the door body 1 is rotatably connected to the door frame 2.

[0050] Figure 7 As shown, the above-mentioned first-stage adjusting seat 16 includes two first adjusting plates 24 symmetrically arranged before and after on the mounting seat 13. The first adjusting plate 24 can move relative to the mounting seat 13 in the X-axis direction. The first limiting slot hole 25 is opened on the first adjusting plate 24. Preferably, the first limiting slot hole 25 is a straight slot with an extension length in the Z-axis direction.

[0051] The above-mentioned second-stage adjusting seat 15 includes two second adjusting plates 23 symmetrically arranged before and after on the mounting seat 13. The two second adjusting plates 23 are respectively arranged outside the two first adjusting plates 24, and the second adjusting plate 23 is arranged parallel to the first adjusting plate 24. The second adjusting plate 23 can move relative to the mounting seat 13 in the X-axis direction. The second limiting slot hole 21 is opened on the second adjusting plate 23. Preferably, the second limiting slot hole 21 is an inclined slot or an arc slot with an extension length in the X-axis direction and an extension length in the Z-axis direction.

[0052] Figure 8 、 Figure 9As shown, specifically, a limiting slot three 19 is provided on the adjustment plate 1 24, and a limiting slot four 18 corresponding to the limiting slot three 19 is provided on the adjustment plate 23. The limiting slot three 19 and the limiting slot four 18 both have an extension length in the X-axis direction. A mounting block 29 located between the two adjustment plates 1 24 is fixed on the mounting seat 13. Preferably, the number of limiting slot three 19 on a single adjustment plate 1 24 is two, and the two limiting slot three 19 are distributed left and right on the adjustment plate 1 24. A single adjustment plate 23 Two limiting slots 18 are provided on the mounting base 13, corresponding to the two limiting slots 19.

Two limiting rods 17 are provided on both sides of the mounting blocks 29, which cooperate with the limiting slots 19 and the limiting slots 18 on both sides. The limiting rods 17 are simultaneously inserted into the corresponding limiting slots 19 and the limiting slots 18 on the same side, thereby limiting the adjustment plate 14 and the adjustment plate 23 on the mounting base 13 and allowing them to move relative to the mounting base 13 along the X-axis. The two limiting slots 19 on the adjustment plate 14, the two limiting slots 18 on the adjustment plate 23, and the two mounting blocks 29 fixed to the mounting base 13 cooperate to ensure that the adjustment plate 14 and the adjustment plate 23 are more stable when they are installed on the mounting base 13 and move relative to the mounting base 13.

[0053] In addition, the end of the limit rod 2 17 extends from the limit slot hole 4 18 to the outside of the adjustment plate 23, and a limit block is fixed on the protruding end. The size of the limit block is larger than the width of the limit slot hole 4 18. The limit block 4 limits the adjustment plate 1 24 and the adjustment plate 2 23 from disengaging from the limit rod 2 17, and the width of the mounting block 29 is equal to the distance between the two adjustment plates 1 24. The limit blocks on the ends of the limit rod 2 17 on both sides cooperate with the mounting block 29 in the middle to clamp the adjustment plate 1 24 and the adjustment plate 2 23 in the middle limit, so that the adjustment plate 1 24 and the adjustment plate 2 23 are connected to the mounting seat 13, and the adjustment plate 1 24 can move relative to the mounting seat 13 in the X-axis direction along the limit slot hole 3 19, and the adjustment plate 2 23 can move relative to the mounting seat 13 in the X-axis direction along the limit slot hole 4 18, and the limit slot hole 3 19 and the limit slot hole 4 18 can limit the range of movement of the adjustment plate 1 24 and the adjustment plate 2 23 relative to the mounting seat 13.

[0054] Preferably, the limiting slot three 19 and the limiting slot four 18 are both straight slots arranged in the X-axis direction, and the width of the limiting slot three 19 and the limiting slot four 18 is equal to the diameter of the limiting rod two 17, so that the connection between the adjustment plate one 24 and the adjustment plate two 23 and the mounting seat 13 is more stable.

[0055] Figure 8 、 Figure 10As shown, in addition, a three-stage adjustment seat 30 is fixed on the shaft core 8, and the three-stage adjustment seat 30 is located between the two adjustment plates 1 24. A limiting rod 1 22 that cooperates with the limiting slot 1 25 and the limiting slot 2 21 is fixed on both sides of the three-stage adjustment seat 30. Preferably, two limiting slots 1 25 are provided on a single adjustment plate 1 24, and the two limiting slots 1 25 are distributed on the adjustment plate 1 24.

Two limiting rods 1 22 corresponding to the limiting slot 1 25 are provided on both sides of the three-stage adjustment seat 30. The limiting rod 1 22 is simultaneously inserted into the corresponding limiting slot 1 25 and limiting slot 2 21 on the same side to limit the shaft core 8 to move on the adjustment plate 1 24 and the adjustment plate 2 23. The limiting slot 1 25 and limiting slot 2 21 cooperate with the limiting rod 1 22 to limit the shaft core 8 to move on the adjustment plate 1 24 and the adjustment plate 2 23. The two limiting slots 1 25, the two limiting slots 21, and the two limiting rods 1 22 on both sides cooperate with each other to make the connection between the three-stage adjustment seat 30 and the adjustment plate 1 24 and the adjustment plate 2 23 on both sides more stable.

[0056] In addition, the end of the limiting rod 1 22 extends from the limiting slot 21 to the outside of the adjustment plate 2 23, and a limiting baffle is fixed on the extended end. The size of the limiting baffle is larger than the width of the limiting slot 21. The limiting baffles on both sides are respectively attached to the outside of the adjustment plates 2 23 on both sides, limiting the three-stage adjustment seat 30 from swinging back and forth between the two adjustment plates 1 24, making the shaft core 8 more stable.

[0057] The diameter of the limiting rod 1 22 is equal to the width of the limiting slot 1 25, and the diameter of the limiting rod 1 22 is equal to the width of the limiting slot 2 21, so that the connection between the three-stage adjustment seat 30 and the adjustment plate 1 24 and the adjustment plate 2 23 on both sides is more stable, and the adjustment plate 1 24 and the adjustment plate 2 23 can better limit the movement of the shaft core 8 when they do not move relative to the mounting seat 13, and can more accurately push the shaft core 8 to move when the adjustment plate 1 24 and the adjustment plate 2 23 move relative to the mounting seat 13.

[0058] The three-stage adjustment seat 30 is located between the two mounting blocks 29 .

[0059] The first adjustment mechanism is used to drive the adjustment plate 1 24 and the adjustment plate 2 23 to move relative to each other in the X-axis direction, and the second adjustment mechanism is used to drive the adjustment plate 1 24 and the adjustment plate 2 23 to move synchronously in the X-axis direction.

[0060] Figure 10As shown in the figure, the first adjustment mechanism includes a first adjustment bolt 33 and a first adjustment block 28. The first adjustment block 28 is located between two first adjustment plates 24 and can move relative to the first adjustment plates 24 in the X-axis direction. Both sides of the first adjustment block 28 are fixedly connected to the second adjustment plates 23 on both sides respectively. Two limiting plates 27 arranged at intervals left and right are fixed between the two first adjustment plates 24. The head of the first adjustment bolt 33 is located between the two limiting plates 27. The threaded rod of the first adjustment bolt 33 passes through the left limiting plate 27 and is threadedly connected to the first adjustment block 28 located on the left side of the limiting plate 27. A through hole one 37 for the threaded rod of the first adjustment bolt 33 to pass through is provided on the left limiting plate 27. A through hole one 36 for a tool for rotating the first adjustment bolt 33 to extend into is provided on the right limiting plate 27. The size of the head of the first adjustment bolt 33 is larger than the sizes of the through hole one 37 and the through hole one 36. When the first adjustment bolt 33 rotates forward or backward, the head can abut against the left or right limiting plate 27, causing the first adjustment block 28 to move left and right in the X-axis direction relative to the first adjustment plates 24. The first adjustment block 28 drives the second adjustment plates 23 to move left and right in the X-axis direction relative to the first adjustment plates 24.

[0061] Preferably, the first adjustment bolt 33 is an internal hexagonal bolt. By inserting an internal hexagonal wrench through the through hole one 36 into the first adjustment bolt 33, the first adjustment bolt 33 can be driven to rotate.

[0062] The widths of the two limiting plates 27 are slightly larger than the width of the head of the first adjustment bolt 33. When the first adjustment bolt 33 rotates, the head of the first adjustment bolt 33 can move a certain distance to the left or right before abutting against the left or right limiting plate 27, which is convenient for rotating the first adjustment bolt 33.

[0063] In addition, connecting rods 20 are provided on both sides of the first adjustment block 28. The connecting rods 20 on both sides pass through the first adjustment plates 24 on both sides respectively and are fixedly connected to the second adjustment plates 23 on both sides. The first adjustment plates 24 are provided with moving holes one 26 for the connecting rods 20 to pass through. The moving holes one 26 have an extended length for the connecting rods 20 to move in the X-axis direction. The width of the moving holes one 26 is equal to the diameter of the connecting rod 20 one.

[0064] Figure 9As shown in the figure, the second adjusting mechanism includes a second adjusting bolt 32 and a second adjusting block 31 fixed on the mounting base 13. The second adjusting block 31 is located between the two adjusting plates 24. The head of the second adjusting bolt 32 is located between the two limiting plates 27. The threaded rod of the second adjusting bolt 32 passes through the left limiting plate 27 and is threadedly connected to the second adjusting block 31 located on the left side of the limiting plate 27. A second through hole 35 for the threaded rod of the second adjusting bolt 32 to pass through is provided on the left limiting plate 27, and a through hole 34 for a tool for rotating the second adjusting bolt 32 to extend into is provided on the right limiting plate 27. The size of the head of the second adjusting bolt 32 is larger than the sizes of the second through hole 35 and the through hole 34. When the second adjusting bolt 32 rotates forward or backward, the head can abut against the left or right limiting plate 27, so that the first adjusting plate 24, the second adjusting plate 23 and the mandrel are combined into a whole and move relative to the mounting base 13 in the X-axis direction together, realizing the left and right movement adjustment of the mandrel.

[0065] Preferably, the second adjusting bolt 32 is an internal hexagonal bolt, and an internal hexagonal wrench can be inserted into the second adjusting bolt 32 through the through hole 34 to drive the second adjusting bolt 32 to rotate.

[0066] The widths of the two limiting plates 27 are slightly larger than the width of the head of the second adjusting bolt 32. When the second adjusting bolt 32 rotates, the head of the second adjusting bolt 32 can move a certain distance to the left or right before abutting against the left or right limiting plate 27, which is convenient for rotating the second adjusting bolt 32.

[0067] The second adjusting block 31 is one of the above-mentioned mounting blocks 29.

[0068] Principle of adjustment of left and right movement and up and down movement of shaft core 8: When it is necessary to adjust the up and down movement of shaft core 8, the first adjusting bolt 33 is rotated by a tool so that the head of the first adjusting bolt 33 rotates and presses against the left or right limit plate 27, and the first adjusting bolt 33 is continued to be rotated. Since the limit plate 27 is fixed to the adjustment plate 1 24, the head of the first adjusting bolt 33 presses against the limit plate 27 and rotates to make the first adjusting block 28 move left or right relative to the adjustment plate 1 24 in the X-axis direction, and the first adjusting block 28 drives the adjustment plate 2 2 The relative adjustment plate 1 24 moves leftward or rightward in the X-axis direction, so that the limiting slot hole 21 moves left and right relative to the limiting slot hole 1 25 in the X-axis direction. Since the limiting slot hole 1 25 limits the movement of the shaft core 8 in the Z-axis direction, the limiting slot hole 21 is an oblique slot or an arc-shaped slot. When the limiting slot hole 21 moves relative to the limiting slot hole 1 25, the limiting slot hole 21 pushes the limiting rod 1 22 to move up and down along the limiting slot hole 1 25 in the Z-axis direction, and the limiting rod 1 22 drives the shaft core 8 to move up and down in the Z-axis direction relative to the mounting seat 13. When the shaft core 8 needs to be adjusted to move left and right, the second adjusting bolt 32 is rotated by a tool so that the head of the second adjusting bolt 32 rotates and presses against the left or right limit plate 27. The second adjusting bolt 32 is continued to be rotated. Since the limit plate 27 is fixed to the adjustment plate 1 24, the second adjustment block 31 is fixed to the mounting seat 13, the head of the second adjusting bolt 32 presses against the limit plate 27 and rotates so that the second adjusting bolt 32 moves left and right in the X-axis direction relative to the second adjustment block 31. The head of the second adjusting bolt 32 passes through the limit plate 27 during the movement. The limiting plate 27 pushes the adjustment plate 1 24 to move left and right relative to the mounting seat 13 in the X-axis direction. The adjustment plate 1 24 pushes the limiting rod 1 22 to move left and right relative to the mounting seat 13 in the X-axis direction through the limiting slot 1 25. The limiting rod 1 22 drives the shaft core 8 to move left and right relative to the mounting seat 13 in the X-axis direction. During the movement, the limiting rod 1 22 can push the adjustment plate 2 23 to move together through the limiting slot 2 21, so that the adjustment plate 1 24, the adjustment plate 2 23 and the shaft core 8 are combined into a whole and move left and right relative to the mounting seat 13 in the X-axis direction.

[0069] The first adjustment mechanism and the second adjustment mechanism only perform fine adjustment on the shaft core 8 .

[0070] Figure 2 As shown, in addition, an adjustment channel 4 corresponding to the above-mentioned through hole 1 36 and through hole 2 34 is provided on one side wall of the door body 1, and the adjustment channel 4 is connected to the through hole 1 36 and through hole 2 34. The adjustment channel 4 is used for the above-mentioned tool to extend and insert into the through hole 1 36 or the through hole 2 34 to rotate the first adjustment bolt 33 or the second adjustment bolt 32.

[0071] Preferably, there are two adjustment channels 4, and the two adjustment channels 4 are respectively docked and communicated with the first through hole 36 and the second through hole 34. Since the distance between the side wall of the door body 1 and the first through hole 36 and the second through hole 34 is relatively long, the two adjustment channels 4 respectively corresponding to the first through hole 36 and the second through hole 34 alone can prevent the tool from wobbling when inserted, resulting in the tool being unable to be correctly inserted into the first through hole 36 or the second through hole 34.

[0072] Figure 3 As shown, in addition, the mounting seat 13 is provided with a second movable hole 14 for the shaft core 8 to extend out. The shaft core 8 extends out from the second movable hole 14 and is inserted into the upper shaft hole 7. The second movable hole 14 has an extension length for the shaft core 8 to move in the X-axis direction. When the second adjustment mechanism adjusts the shaft core 8 to move left and right, the shaft core 8 can move left and right in the second movable hole 14.

[0073] In addition, the width of the second movable hole 14 is equal to the outer diameter of the shaft core 8, which avoids the shaft core 8 from shaking back and forth and makes the shaft core 8 more stable during use.

[0074] A wear-resistant sleeve 10 is installed in the shaft hole 7. The wear-resistant sleeve 10 is tightly inserted into the shaft hole 7. When the door body 1 is installed on the door frame 2, the shaft core 8 is inserted into the wear-resistant sleeve 10, and the outer diameter of the shaft core 8 is equal to the inner diameter of the wear-resistant sleeve 10. The wear-resistant sleeve 10 is made of plastic material, and the wear-resistant sleeve 10 is spaced between the inner wall of the shaft hole 7 and the shaft core 8, slowing down the wear caused by the contact between the shaft core 8 and the inner wall of the shaft hole 7.

[0075] Figure 3 As shown, in addition, the shaft core 8 is provided with a wire passing channel 9 extending along the axial direction of the shaft core 8. The wire passing channel 9 penetrates through both ends of the shaft core 8 for passing wires. The electric control integrated circuit of the revolving door can be directly connected into the door body 1 through the wire passing channel 9 on the shaft core 8, realizing the corresponding connection between the internal system and the external system of the door, achieving the concealed wiring of the electric control integrated circuit, and realizing the overall aesthetic appearance of the revolving door.
