The clutch assembly includes a housing, a fixed sleeve, a rotating sleeve, and a clutch sleeve. The housing is detachably connected to the housing assembly. The fixed sleeve is fixed inside the housing. The rotating sleeve is fixed to one end of the lead screw and rotatably connected to the fixed sleeve. The clutch sleeve is sleeved outside the rotating sleeve and rotatably connected to the rotating sleeve. The clutch sleeve is fixed to the large gear. When the clutch assembly is energized, the rotating sleeve and the clutch sleeve are attracted to each other. The motor drives the large gear to rotate through the small gear. The large gear drives the lead screw to rotate through the clutch sleeve and the rotating sleeve, thereby realizing the extension and retraction of the push rod.

[0005] To facilitate the sliding guidance of the push rod, a push rod sleeve is detachably connected to one end of the push rod. The push rod sleeve slides along the inner wall of the housing assembly, and several sealing rings are provided between the push rod sleeve and the inner wall of the housing assembly.

[0006] To facilitate the overall disassembly and assembly of the clutch assembly, one end of the housing assembly has a flange end face, and the outer shell is detachably connected to the flange end face by screws.

[0007] To facilitate the rotation of the lead screw, one end of the lead screw is rotatably connected to the housing assembly via a first bearing, and the outer end face of the bearing is flush with the flange end face.

[0008] To prevent the large gear from colliding with the flange end face, a limiting washer is fixed on the outside of the bearing, and the limiting washer abuts against the large gear.

[0009] To facilitate relative rotation, one end of the rotating sleeve is rotatably connected to the fixed sleeve via a second bearing, and the clutch sleeve is rotatably connected to the rotating sleeve via a third bearing.

[0010] The present invention also provides an electric locking shielding door, wherein the electric locking shielding door is equipped with the above-mentioned manual-automatic integrated clutch push rod structure.

[0012] Figure 1 This is a schematic diagram of the manual / automatic integrated clutch push rod structure of the present invention; Figure 2 This is a schematic diagram of the structure of the electric locking shielding door of the present invention. Detailed Implementation

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0014] Example 1: like Figure 1 The manual / automatic integrated clutch push rod structure shown includes a housing assembly 1, a push rod assembly disposed within the housing assembly 1, and a motor assembly disposed outside the housing assembly 1. The motor assembly and the push rod assembly are connected through a clutch assembly.

[0015] Specifically, the housing assembly 1 is a cylindrical hollow structure with a through hole at its right end, through which the push rod of the push rod assembly passes and extends to the outside of the housing assembly 1. Its left end is an open end and is integrally formed with a flange end face 12 for installing the clutch assembly.

[0016] Specifically, the motor assembly is installed on one side outside the housing assembly 1. The motor assembly includes a motor 2 and a pinion 3. The motor 2 is connected to the pinion 3 and can drive the pinion 3 to rotate.

[0017] Specifically, the push rod assembly includes a push rod 4, a lead screw 5, and a large gear 6. The left end of the push rod 4 is detachably connected to a push rod sleeve 9, which slides along the inner wall of the housing assembly 1. Several sealing rings 10 are provided between the push rod sleeve 9 and the inner wall of the housing assembly 1. The right end of the push rod 4 extends to the outside of the housing assembly 1. The lead screw 5 is coaxially arranged with the push rod 4 and threadedly connected to the push rod sleeve 9 on the push rod 4. The lead screw 5 is rotatably connected to the housing assembly 1 through a first bearing 11. The outer end face of the first bearing 11 is flush with the flange end face 12. The left end of the lead screw 5 has an extension section 8 that extends to the outside of the housing assembly 1. The large gear 6 is fixed to the right side of the extension section 8 of the lead screw 5. The large gear 6 meshes with the small gear 3, and there is a gap between the large gear 6 and the flange end face 12. A limiting washer 21 is fixed to the outside of the first bearing 11. The limiting washer 21 is disposed in the gap and abuts against the large gear 6.

[0018] Specifically, the clutch assembly includes a housing 7, a fixed sleeve 17, a rotating sleeve 16, and a clutch sleeve 15. The housing 7 is detachably connected to the flange end face 12 of the housing assembly 1 by screws 13. The fixed sleeve 17 is fixed inside the housing 7 by screws 14. The rotating sleeve 16 is fixed on the extension section 8 of the lead screw 5 and is rotatably connected to the fixed sleeve 17 by a second bearing 18. The clutch sleeve 15 is sleeved outside the rotating sleeve 16 and is rotatably connected to the rotating sleeve 16 by a third bearing 19. The clutch sleeve 15 is fixed to the large gear 6. The extension section 8 of the lead screw 5 extends outside the housing 7 and is fixed with a rotating nut 20.

[0019] When the clutch assembly is energized, it switches to electric mode. At this time, the rotating sleeve 16 attracts the clutch sleeve 15, the motor 2 drives the pinion 3 to rotate, the pinion 3 drives the large gear 6 to rotate, and the large gear drives the clutch sleeve 15 to rotate. Since the rotating sleeve 16 is attracted to the clutch sleeve 15 at this time, the rotating sleeve 16 drives the lead screw 5 to rotate, and the lead screw 5 realizes the extension and retraction movement of the push rod 4 through the push rod sleeve 9. When the clutch assembly is not powered, switch to manual mode. At this time, the rotating sleeve 16 is separated from the clutch sleeve 15. By manually rotating the rotating nut 20, the extension section 8 and the lead screw 5 can be directly rotated, which can also realize the extension and retraction of the push rod 4.

[0020] Example 2: like Figure 2 As shown, this embodiment provides an electrically locking shielding door A, on which the above-mentioned manual-automatic integrated clutch push rod structure B is installed. The manual-automatic integrated clutch push rod structure B realizes the locking and unlocking of the latch through the linkage mechanism C. The manual-automatic integrated clutch push rod structure B can realize manual and electric switching, which is convenient to use.
