Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-8 A quick installation and disassembly mechanism for a disposable sheet toilet paper roll provided in this embodiment includes a fixed plate 1 and an opening and closing plate 2. A toilet paper roll 3 is installed between the fixed plate 1 and the opening and closing plate 2. An active rotation mechanism is provided inside the fixed plate 1, which is driven by a rotating motor 102. The rotating motor 102 is installed outside the fixed plate support 103 and fixed with a motor fixing screw 109. The output end of the rotating motor 102 is provided with a sleeve rotating shaft 107 and a sleeve support 106. The sleeve rotating shaft 107 passes through the sleeve support 106 and is installed on the rotating motor 102. By rotating the rotating motor 102, the sleeve rotating shaft 107 is driven, thereby driving the sleeve support 106 to rotate. The sleeve support 106 is equipped with a key block 104 and fixed with a key block fixing screw 105. The key block 104 is used in cooperation with the opening on the toilet paper roll 3, thereby driving the toilet paper roll 3 to rotate. A fixed plate protective cover 101 is installed outside the rotating motor 102 to play a safety protection role.

[0024] The opening and closing plate 2 in this embodiment includes an opening and closing plate shield 201, a hinge 202, an opening and closing plate support 203, a spring bolt 205, and a lock piece 207; one end of the hinge 202 and the spring bolt 205 are respectively installed and fixed on the opening and closing plate support 203. The sleeve support 106 is installed on the opening and closing plate support 203 by means of pin connection. The inner hole of the sleeve support 106 is equipped with a bearing 111. The opening and closing plate shield 201 is installed on the outside of the opening and closing plate support 203; the other end of the hinge 202 is fixed to one side of the bed frame with a fixing bolt. The opening and closing plate 2 performs opening and closing actions through the hinge 202, and the spring bolt 205 installed inside is used to lock and unlock the opening and closing actions; among them, the spring bolt 205 is in a state of protruding upward for a long time under the action of spring force. When the spring bolt 205 aligns with the hole of the lock piece 207, it is in a locked state; pulling the spring bolt 205 downward can unlock the opening and closing plate 2.

[0025] In this embodiment, one side of the opening and closing plate 2 and the paper roll cylinder 3 are oppositely installed and aligned on the fixing plate 1. The sleeve support 106 is aligned with the paper roll cylinder 3 to play a role in supporting and clamping. (The key block 104 on the sleeve support 106 is aligned with the opening on the paper roll cylinder 3 for installation. During the implementation, the paper roll cylinder 3 can be driven to rotate by the driving force of the rotating motor 102.) After aligning with one side of the fixing plate 1, rotate the opening and closing plate 2 inward, align the sleeve support 106 on the right side with the paper roll cylinder 3, and lock the opening and closing plate 2. The sleeve supports 106 on both sides can play a role in supporting and clamping the paper roll cylinder 3. This structure can be used as both the driving structure and the driven structure of the paper roll, and protective covers are installed on both sides to play a protective role and the appearance is neater.

[0026] Working principle: For the quick installation and disassembly mechanism of the disposable bed sheet paper roll cylinder of the present utility model, the disposable paper roll cylinder 3 is the driving rotation mechanism. A keyway hole is opened on the disposable paper roll cylinder 3 and is used in cooperation with the key block 104 fixed on the sleeve support 106. The sleeve support 106 and the rotating motor 102 are fixedly installed on the fixing plate support 103. The rotation of the rotating motor 102 drives the sleeve support 106 to rotate, thereby driving the disposable bed sheet paper roll cylinder 3 to rotate. The other end of the disposable paper roll cylinder 3 is connected to the opening and closing plate support 203 through the sleeve support 106. A bearing 111 is placed inside the sleeve support 106 installed on the opening and closing plate support 203 to make the rotation process smoother and without noise. A hinge 202 is fixedly installed on the opening and closing plate 2, enabling it to perform a 90° rotation action. A spring bolt 205 is installed at the other end of the opening and closing plate 2. A spring is installed inside the spring bolt 205. The spring bolt 205 is in an upward state for a long time under the action of spring force. When the spring bolt 205 aligns with the hole of the lock piece 207, it is in a locked state. Pulling the spring bolt 205 downward can unlock the opening and closing plate 2. After the opening and closing plate 2 is unlocked, the disposable paper roll cylinder 3 can be easily removed and replaced.
