[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. The principles and features of the present invention are described below in combination with the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0039] Example 1

[0040] Reference Figures 1 to 6 This embodiment provides an adaptive and adjustable frame pressing mechanism, which is characterized by comprising:

[0041] Base 14;

[0042] The lead screw 3 is mounted between two vertical plates 12 on the base 14, and threads in opposite directions are arranged at two ends of the lead screw 3. The first flange nut 22 and the second flange nut 24 are respectively arranged on the threads at two opposite ends of the lead screw 3;

[0043] The first pressing frame 10 is connected to the first flange nut 22. The first pressing frame 10 includes two long pressing plates 19. The length directions of the two pressing plates 19 are parallel.

[0044] The second pressing frame 7 is connected to the second flange nut 24 . The second pressing frame 7 includes two long pressing plates 19 . The length directions of the two pressing plates 19 are parallel.

[0045] When the lead screw rotates, the first pressing frame 10 and the second pressing frame 7 move toward or away from each other to adjust the size of the entire pressing frame composed of the two, so it is suitable for fixing clothes when opening pockets of various sizes.

[0046] A bearing may be installed in the vertical plate 12 to reduce the friction between the screw rod 3 and the vertical plate 12. The bearing may be a ball bearing or other types of bearings, and the type of the bearing is not limited here.

[0047] In this embodiment, the bottoms of the first pressing frame 10 and the second pressing frame 7 are provided with anti-slip grooves, and the design purpose of the anti-slip grooves is to improve the close contact between the first pressing frame 10, the second pressing frame 7 and the clothes.

[0048] In this embodiment, the adaptively adjustable frame pressing mechanism further comprises:

[0049] The first limiting plate 9 is in the shape of an elongated strip, one end of which is fixed to the first pressing frame 10 and the other end of which extends toward the second pressing frame 7;

[0050] The second limiting plate 8 is in the shape of an elongated strip, one end of which is fixed on the second pressing frame 7 and the other end of which extends toward the first pressing frame 10 .

[0051] The first pressing frame 10 and the second pressing frame 7 have a certain elasticity, and will warp when pressing down on the clothes. Therefore, the first pressing frame 10 and the second pressing frame 7 are provided with a first limiting plate 9 and a second limiting plate 8. When the first pressing frame 10 warps, the second limiting plate 8 presses down the first pressing frame 10 to make the first pressing frame 10 and the second pressing frame 7 parallel; similarly, the first limiting plate 9 presses down the second pressing frame 7 to make the first pressing frame 10 and the second pressing frame 7 parallel, so that they are fixed around the opening.

[0052] Furthermore, a first limiting plate 9 is fixed above each of the two pressing plates 19 of the first pressing frame 10;

[0053] A second limiting plate 8 is fixed above each of the two pressing plates 19 of the second pressing frame 7 .

[0054] In this embodiment, the first pressing frame 10 and the second pressing frame 7 both have a connecting plate 6 in a vertical direction;

[0055] The self-adaptive and adjustable frame pressing mechanism further comprises:

[0056] A first connecting member 11, connecting the first flange nut 22 and the connecting plate 6 of the first pressing frame 10;

[0057] The second connecting member 5 connects the second flange nut 24 and the connecting plate 6 of the second pressing frame 7 .

[0058] The first connecting member 11 and the second connecting member 5 have a certain thickness, so that they have a certain rigidity to prevent deformation; when the thickness of the first connecting member 11 and the second connecting member 5 is relatively large, the contact area between the first connecting member 11 and the screw rod 3 can be increased, thereby improving the movement stability of the first connecting member 11 and the second connecting member 5, but the processing cost is relatively high, and the specific thickness is determined based on the balance between cost and effect.

[0059] In this embodiment, the first connecting member 11 is provided with a plurality of waist-shaped holes and a plurality of threaded holes horizontal in the length direction;

[0060] The second connecting member 5 is also provided with a plurality of waist-shaped holes and a plurality of threaded holes horizontal in the length direction;

[0061] The connecting plate 6 is also provided with a plurality of waist-shaped holes 20 and a plurality of threaded holes 21 which are horizontal in the length direction.

[0062] The threaded holes are used to install adjustment screws, which are used to adjust the angles of the first pressing frame and the second pressing frame. There will be certain errors in the processing of parts. To ensure that the first pressing frame is fully pressed on the clothes, before fixing the first pressing frame, first tighten the adjustment screws to the appropriate position and then fix it.

[0063] The waist-shaped hole enables the distance between the first pressing frame 10 and the second pressing frame 7 to be adjustable.

[0064] In this embodiment, a guide rail 17 is also provided on the base 14;

[0065] The first connecting member 11 and the second connecting member 5 are both provided with a slider 18 slidably connected to the guide rail 17 .

[0066] The guide rail 17 and the slider are mainly used to limit the first pressing frame 10 and the second pressing frame 7 so that they can only move in a straight line; secondly, the provision of the guide rail 17 and the slider can reduce the resistance to the movement of the first pressing frame 10 and the second pressing frame 7.

[0067] In this embodiment, one end of the lead screw 3 is connected to the first bevel gear 4, and the adaptively adjustable frame pressing mechanism further includes:

[0068] The motor 1 is mounted on the base 14, and the output end of the motor 1 is connected to the second bevel gear 2;

[0069] The first bevel gear 4 is meshed with the second bevel gear 2 .

[0070] In this embodiment, the adaptively adjustable frame pressing mechanism further comprises:

[0071] The base 15 has a cylinder 16 mounted on it, and an output end of the cylinder 16 is connected to the pedestal 14 .

[0072] The motor 1 can be arranged on one side of the cylinder 16, so that the adaptive adjustable frame pressing mechanism provided in this embodiment has a compact structure. In other embodiments, the motor 1 can also be directly connected to the screw rod 3 through a coupling, and the mechanism driving the screw rod 3 to rotate is not restricted.

[0073] In this embodiment, a limit sensor 13 is installed on the base 14, and the limit sensor 13 is used to monitor the position of the first flange nut 22, thereby monitoring the position of the first pressing frame 10 to prevent the first pressing frame 2 from moving to the limit position.

[0074] In this embodiment, the two pressing plates 19 of the first pressing frame 10 are bent toward each other at one end away from the second pressing frame 7;

[0075] The two pressing plates 19 of the second pressing frame 7 are bent toward each other at their ends away from the first pressing frame 10 .
