[0039] Before the embodiments of the present application are explained in detail, the application scenarios of the embodiments of the present application are described.

[0040] The sheet cloth mounting mechanism provided by the embodiments of the present application can be applied in the scene of mounting the sheet cloth to the mounting object, and can simply and conveniently realize the mounting of the sheet cloth, thereby improving the user experience.

[0041] For example, in daily household cleaning work, in order to ensure the cleaning effect, a disposable wiping cloth is often used for cleaning. When in use, a piece of wiping cloth is torn off and is sleeved on the cleaning head of a broom to perform cleaning work, and the wiping cloth is directly discarded after the cleaning is completed. In this case, the sheet cloth mounting mechanism provided by the embodiments of the present application can be used to mount the wiping cloth on the cleaning head of the broom, and the mounting process is simple and convenient.

[0042] The sheet cloth mounting mechanism provided by the embodiments of the present application is described below.

[0043] Figure 1 is a structural schematic diagram of a sheet cloth mounting mechanism provided by the embodiments of the present application. Referring to Figure 1 The sheet cloth mounting mechanism includes a bearing structure 1, a first pressing structure 2 and a second pressing structure 3. The bearing structure 1 is located between the first pressing structure 2 and the second pressing structure 3, the bearing structure 1 can be in contact with the first pressing structure 2 and the second pressing structure 3, and the bearing structure 1 is used to bear the sheet cloth. When the bearing structure 1 moves, the first pressing structure 2 and the second pressing structure 3 can be driven to move towards each other; when the first pressing structure 2 and the second pressing structure 3 move towards each other, the sheet cloth can be pressed close to the mounting object.

[0044] The bearing structure 1 is a structure for bearing a sheet-shaped cloth. The bearing structure 1 is located between the first pressing structure 2 and the second pressing structure 3, and the bearing structure 1 can resist the first pressing structure 2 and the second pressing structure 3 when moving, so as to move the first pressing structure 2 and the second pressing structure 3. Optionally, when the bearing structure 1 moves, the first pressing structure 2 and the second pressing structure 3 can not only move towards each other, but also move away from each other. In this case, the bearing structure 1 moves in one direction, so as to move the first pressing structure 2 and the second pressing structure 3 towards each other, and then the bearing structure 1 moves in the opposite direction, so as to move the first pressing structure 2 and the second pressing structure 3 away from each other.

[0045] The first pressing structure 2 and the second pressing structure 3 are structures for pressing a sheet-shaped cloth. The sheet-shaped cloth can be placed in the space between the first pressing structure 2 and the second pressing structure 3, i.e. on the bearing structure 1. In this way, when the first pressing structure 2 and the second pressing structure 3 move towards each other, the space between the first pressing structure 2 and the second pressing structure 3 becomes smaller, so as to press the two sides of the sheet-shaped cloth and fold the sheet-shaped cloth inward, until the sheet-shaped cloth is pressed close to the installation object. When the sheet-shaped cloth is close to the installation object, it can be installed on the installation object. For example, one of the sheet-shaped cloth and the installation object can be provided with a magic tape fluff surface, and the other can be provided with a magic tape hook surface. When the sheet-shaped cloth is close to the installation object, the magic tape fluff surface and the magic tape hook surface are pasted, so as to fix the sheet-shaped cloth on the installation object. For example, the sheet-shaped cloth can be a cleaning cloth with cleaning function, and the installation object can be a cleaning head of a broom. After the cleaning cloth is installed on the cleaning head of the broom, the cleaning work can be performed.

[0046] In some embodiments, a plurality of sheet-shaped cloths can be stacked and placed on the bearing structure 1. In this case, when the first pressing structure 2 and the second pressing structure 3 move towards each other each time, the uppermost sheet-shaped cloth in the plurality of sheet-shaped cloths can be installed on the installation object. In this way, the sheet-shaped cloth installation mechanism can realize the sequential installation of the plurality of sheet-shaped cloths. For example, the plurality of sheet-shaped cloths can all be cleaning cloths with cleaning function, and the installation object can be a cleaning head of a broom. When the user wants to clean, the user can install a cleaning cloth on the cleaning head of the broom through the sheet-shaped cloth installation mechanism, and then the user can use the cleaning cloth on the cleaning head of the broom to perform the cleaning work. After the cleaning is completed, the user can directly throw away the cleaning cloth, and then install a new cleaning cloth on the cleaning head of the broom through the sheet-shaped cloth installation mechanism to continue the cleaning work.

[0047] Specifically, the sheet cloth mounting mechanism places the sheet cloth in the space between the first pressing structure 2 and the second pressing structure 3, i.e. on the bearing structure 1, before use. In use, the sheet cloth mounting mechanism first places the mounting object in the space between the first pressing structure 2 and the second pressing structure 3, i.e. in the position of the bearing structure 1, and then applies force to the bearing structure 1 through the mounting object, so that the bearing structure 1 moves and abuts against the first pressing structure 2 and the second pressing structure 3, causing the first pressing structure 2 and the second pressing structure 3 to move towards each other. At this time, the space between the first pressing structure 2 and the second pressing structure 3 becomes smaller, so that the sheet cloth can be pressed close to the mounting object, i.e. mounted on the mounting object. The mounting process is simple and convenient, which can improve the user experience. After the sheet cloth is mounted on the mounting object, the first pressing structure 2 and the second pressing structure 3 can move away from each other, at which time the space between the first pressing structure 2 and the second pressing structure 3 becomes larger, so that the mounting object can be taken out from the space between the first pressing structure 2 and the second pressing structure 3. After the mounting object is taken out, the sheet cloth mounted on the mounting object can be used.

[0048] Optionally, referring to Figure 1 , the bearing structure 1 comprises a bearing plate 11 for placing the sheet cloth. The bearing plate 11 can be in contact with the first pressing structure 2 and the second pressing structure 3, and the bearing plate 11 abuts against the first pressing structure 2 and the second pressing structure 3 when subjected to external force, causing the first pressing structure 2 and the second pressing structure 3 to rotate towards each other.

[0049] The bearing plate 11 is a component that can drive the first pressing structure 2 and the second pressing structure 3 to rotate towards each other. In this case, the sheet cloth mounting mechanism first places the mounting object in the space between the first pressing structure 2 and the second pressing structure 3, i.e. in the position of the bearing plate 11, in use, and then applies force to the bearing plate 11 through the mounting object. The bearing plate 11 moves when subjected to external force, and abuts against the first pressing structure 2 and the second pressing structure 3 after moving, causing the first pressing structure 2 and the second pressing structure 3 to rotate towards each other.

[0050] Further, referring to Figure 2 or Figure 3 , Figure 3 is Figure 2 the exploded schematic view of the sheet cloth mounting mechanism shown in FIG. 1, which further comprises a housing 4. The housing 4 is a component that has a supporting effect and can limit the positions of the bearing structure 1, the first pressing structure 2 and the second pressing structure 3.

[0051] The shell 4 can have various structures. For example, the shell 4 can be a one-piece structure, and can have a bottom and a side wall, the bottom and the side wall of the shell 4 enclosing a cavity, and the carrying structure 1, the first pressing structure 2 and the second pressing structure 3 can be placed in the cavity for use. Alternatively, the shell 4 can be a split structure, and can have a bottom plate and a vertical plate, the bottom plate can be referred to as the bottom of the shell 4, and the vertical plate can be referred to as the side wall of the shell 4. Of course, the shell 4 can also have other structures, which are not limited in the embodiments of the present application.

[0052] When the carrying plate 11 is subjected to an external force, the carrying plate 11 moves towards the bottom of the shell 4, and after the carrying plate 11 moves towards the bottom of the shell 4, the carrying plate 11 abuts against the first pressing structure 2 and the second pressing structure 3, so that the first pressing structure 2 and the second pressing structure 3 rotate towards each other.

[0053] Optionally, referring to Figure 1 , Figure 2 and Figure 3 , the first pressing structure 2 is hinged to the shell 4. When the carrying plate 11 is subjected to an external force, the carrying plate 11 abuts against the first pressing structure 2, so that the first pressing structure 2 rotates towards the second pressing structure 3. The second pressing structure 3 is hinged to the shell 4. When the carrying plate 11 is subjected to an external force, the carrying plate 11 abuts against the second pressing structure 3, so that the second pressing structure 3 rotates towards the first pressing structure 2.

[0054] After the first pressing structure 2 is hinged to the shell 4, the first pressing structure 2 can rotate around the hinged part as the center. Similarly, after the second pressing structure 3 is hinged to the shell 4, the second pressing structure 3 can also rotate around the hinged part as the center. In this way, when the carrying plate 11 moves towards the bottom of the shell 4 under the external force, the carrying plate 11 abuts against the first pressing structure 2 and the second pressing structure 3, so that the first pressing structure 2 and the second pressing structure 3 rotate inwards around the respective hinged parts, i.e., rotate towards each other.

[0055] Optionally, referring to Figure 1 , Figure 2 and Figure 3 , the first pressing structure 2 comprises a first movable rod 21. The rod body of the first movable rod 21 is hinged to the shell 4, and the first end 211 of the first movable rod 21 can contact the carrying plate 11; when the carrying plate 11 is subjected to an external force, the carrying plate 11 abuts against the first end 211 of the first movable rod 21, so that the second end 212 of the first movable rod 21 rotates towards the second pressing structure 3.

[0056] The rod body of the first movable rod 21 is hinged to the shell 4, and the first movable rod 21 can rotate around the hinged part 213. For example, the rod body of the first movable rod 21 can be hinged to the side wall of the shell 4, or the rod body of the first movable rod 21 can be hinged to the bottom of the shell 4 through a connecting piece. Of course, the rod body of the first movable rod 21 can be hinged to the shell 4 in other manners, as long as the rod body of the first movable rod 21 can rotate around the hinged part 213 after being hinged to the shell 4.

[0057] In this case, the bearing plate 11 moves towards the bottom of the shell 4 when subjected to an external force, and the bearing plate 11 abuts against the first end 211 of the first movable rod 21 after moving towards the bottom of the shell 4, so as to move the first end 211 of the first movable rod 21, and then rotate the first movable rod 21 inwards. When the first movable rod 21 rotates inwards, the second end 212 of the first movable rod 21 rotates towards the second pressing structure 3.

[0058] The first end 211 of the first movable rod 21 is used to abut against the bearing plate 11, and the second end 212 of the first movable rod 21 is used to press the sheet-shaped cloth. The first end 211 and the second end 212 of the first movable rod 21 can adopt various structural forms.

[0059] For example, referring to Figure 1 , the first end 211 of the first movable rod 21 can be in the form of a hook, so that the bearing plate 11 can abut against the hook-shaped end of the first movable rod 21 when the bearing plate 11 moves under the action of an external force. Of course, the first end 211 of the first movable rod 21 can also adopt other structural forms, which are not limited in the embodiments of the present application.

[0060] For example, the second end 212 of the first movable rod 21 is provided with a pressing part, so that the pressing part can press the sheet-shaped cloth when the second end 212 of the first movable rod 21 rotates towards the second pressing structure 3. Alternatively, referring to Figure 1 , the first pressing structure 2 further comprises a first pressing plate 23, and the second end 212 of the first movable rod 21 is hinged to or connected to the first pressing plate 23, so that the first pressing plate 23 can press the sheet-shaped cloth when the second end 212 of the first movable rod 21 rotates towards the second pressing structure 3. Of course, the second end 212 of the first movable rod 21 can also adopt other structural forms, which are not limited in the embodiments of the present application.

[0061] It is worth noting that in actual application, the first pressing structure 2 can include a plurality of first movable rods 21. The rod body of each of the plurality of first movable rods 21 is hinged to the shell 4, and the first end 211 of each of the plurality of first movable rods 21 can be in contact with the bearing plate 11; when the bearing plate 11 is subjected to an external force, the first end 211 of each of the plurality of first movable rods 21 is abutted, so that the second end 212 of each of the plurality of first movable rods 21 is rotated towards the second pressing structure 3, so that the second end 212 of each of the plurality of first movable rods 21 can press the sheet-shaped cloth, so that the pressing force on the sheet-shaped cloth can be increased, and the installation efficiency and installation effect of the sheet-shaped cloth can be improved.

[0062] Optionally, referring to Figure 1 、 Figure 2 and Figure 3 , the second pressing structure 3 includes a second movable rod 31. The rod body of the second movable rod 31 is hinged to the shell 4, and the first end 311 of the second movable rod 31 can be in contact with the bearing plate 11; when the bearing plate 11 is subjected to an external force, the first end 311 of the second movable rod 31 is abutted, so that the second end 312 of the second movable rod 31 is rotated towards the first pressing structure 2.

[0063] After the rod body of the second movable rod 31 is hinged to the shell 4, the second movable rod 31 can be rotated around the hinged part 313. For example, the rod body of the second movable rod 31 can be hinged to the side wall of the shell 4, or the rod body of the second movable rod 31 can be hinged to the bottom of the shell 4 through a connecting piece, of course, the rod body of the second movable rod 31 can be hinged to the shell 4 in other ways, as long as the rod body of the second movable rod 31 can be rotated around the hinged part 313 after being hinged to the shell 4.

[0064] In this case, when the bearing plate 11 is subjected to an external force, the bearing plate 11 moves towards the bottom of the shell 4, and after the bearing plate 11 moves towards the bottom of the shell 4, the first end 311 of the second movable rod 31 is abutted, so that the first end 311 of the second movable rod 31 is moved, and then the second movable rod 31 is rotated inwards, and when the second movable rod 31 is rotated inwards, the second end 312 of the second movable rod 31 is rotated towards the first pressing structure 2.

[0065] The first end 311 of the second movable rod 31 is used to abut the bearing plate 11, and the second end 312 of the second movable rod 31 is used to press the sheet-shaped cloth. The first end 311 and the second end 312 of the second movable rod 31 can adopt various structural forms.

[0066] For example, referring to Figure 1The first end 311 of the second movable rod 31 can be in the shape of a hook, so that the carrying plate 11 can abut against the hook-shaped first end 311 of the second movable rod 31 when the carrying plate 11 is moved by an external force. Of course, the first end 311 of the second movable rod 31 can also adopt other structural forms, which are not limited in the embodiments of the present application.

[0067] For example, the second end 312 of the second movable rod 31 is provided with a pressing part, so that the pressing part can press the sheet-shaped cloth when the second end 312 of the second movable rod 31 rotates towards the first pressing structure 2. Figure 1 The second pressing structure 3 further comprises a second pressing plate 33, and the second end 312 of the second movable rod 31 is hinged to or connected to the second pressing plate 33, so that the second pressing plate 33 can press the sheet-shaped cloth when the second end 312 of the second movable rod 31 rotates towards the first pressing structure 2. Of course, the second end 312 of the second movable rod 31 can also adopt other structural forms, which are not limited in the embodiments of the present application.

[0068] It is worth noting that in actual application, the second pressing structure 3 can comprise a plurality of second movable rods 31. The rod body of each second movable rod 31 in the plurality of second movable rods 31 is hinged to the shell 4, and the first end 311 of each second movable rod 31 in the plurality of second movable rods 31 can contact the carrying plate 11. When the carrying plate 11 is subjected to an external force, the first end 311 of each second movable rod 31 in the plurality of second movable rods 31 is abutted, so that the second end 312 of each second movable rod 31 in the plurality of second movable rods 31 rotates towards the first pressing structure 2. Thus, the second end 312 of each second movable rod 31 in the plurality of second movable rods 31 can press the sheet-shaped cloth, so that the pressing force on the sheet-shaped cloth can be increased, and the installation efficiency and installation effect of the sheet-shaped cloth can be improved.

[0069] Optionally, referring to Figure 1 The carrying structure 1 further comprises a first carrying member 12 and a second carrying member 13, and the first carrying member 12 and the second carrying member 13 are movably connected to the carrying plate 11. The first carrying member 12 and the second carrying member 13 are components that can drive the first pressing structure 2 and the second pressing structure 3 to rotate away from each other.

[0070] The first carrying member 12 can drive the first pressing structure 2 to rotate away from the second pressing structure 3. Specifically, when the second end 212 of the first movable rod 21 rotates towards the second pressing structure 3, the first carrying member 12 is driven to move towards the second pressing structure 3; and when the external force on the carrying plate 11 is removed, the first carrying member 12 moves away from the second pressing structure 3 to drive the second end 212 of the first movable rod 21 to rotate away from the second pressing structure 3.

[0071] The second bearing part 13 can drive the second pressing structure 3 to rotate in a direction away from the first pressing structure 2. Specifically, when the second end 312 of the second movable rod 31 rotates in a direction close to the first pressing structure 2, the second bearing part 13 is driven to move in a direction close to the first pressing structure 2; when the external force on the bearing plate 11 is removed, the second bearing part 13 moves in a direction away from the first pressing structure 2 to drive the second end 312 of the second movable rod 31 to rotate in a direction away from the first pressing structure 2.

[0072] In this case, when the sheet-shaped cloth mounting mechanism is in use, the bearing plate 11 is forced by the mounting object, and the bearing plate 11 moves in a direction close to the bottom of the shell 4 when subjected to the external force. After the bearing plate 11 moves in a direction close to the bottom of the shell 4, it abuts against the first end 211 of the first movable rod 21 and the first end 311 of the second movable rod 31, so that the first movable rod 21 and the second movable rod 31 rotate inwards. At this time, the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate in a direction close to each other, and the space between the first movable rod 21 and the second movable rod 31 becomes smaller. The second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 can press the sheet-shaped cloth close to the mounting object, i.e., install the sheet-shaped cloth on the mounting object. At the same time, when the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate in a direction close to each other, the first bearing part 12 and the second bearing part 13 are driven to move in a direction close to each other. After the sheet-shaped cloth is installed on the mounting object, the bearing plate 11 is no longer forced by the mounting object. When the external force on the bearing plate 11 is removed, the first bearing part 12 and the second bearing part 13 move in a direction away from each other to drive the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 to rotate in a direction away from each other, i.e., the first movable rod 21 and the second movable rod 31 rotate outwards. At this time, the space between the first movable rod 21 and the second movable rod 31 becomes larger, so that the mounting object can be taken out.

[0073] The first bearing part 12 and the second bearing part 13 can adopt various structural forms. For example, referring to Figure 1 , the first bearing part 12 can be a first vertical rod, which can penetrate the sheet-shaped cloth to position the sheet-shaped cloth, so that the sheet-shaped cloth can be effectively prevented from being separated from the bearing plate 11. For example, referring to Figure 1 , the second bearing part 13 can be a second vertical rod, which can penetrate the sheet-shaped cloth to position the sheet-shaped cloth, so that the sheet-shaped cloth can be effectively prevented from being separated from the bearing plate 11. Of course, the first bearing part 12 and the second bearing part 13 can also adopt other structural forms, which are not limited in the embodiments of the present application.

[0074] In the case that the first bearing member 12 is a first vertical rod, referring to Figure 1 The first pressing structure 2 can further include a first horizontal rod 22, and the part of the rod body of the first movable rod 21 close to the second end 212 is connected with the first horizontal rod 22, and the first horizontal rod 22 can contact with the first vertical rod. In this way, the first vertical rod can abut against the first horizontal rod 22 when the external force on the bearing plate 11 is removed, so as to drive the first movable rod 21 connected with the first horizontal rod 22 to rotate.

[0075] Specifically, when the second end 212 of the first movable rod 21 rotates towards the direction close to the second pressing structure 3, the first horizontal rod 22 also rotates towards the direction close to the second pressing structure 3, and at this time, the first horizontal rod 22 abuts against the first vertical rod, so that the first vertical rod also moves towards the direction close to the second pressing structure 3. When the first vertical rod moves away from the second pressing structure 3, it abuts against the first horizontal rod 22, so that the first horizontal rod 22 rotates away from the second pressing structure 3, and thus the second end 212 of the first movable rod 21 connected with the first horizontal rod 22 also rotates away from the second pressing structure 3.

[0076] In the case that the second bearing member 13 is a second vertical rod, referring to Figure 1 The second pressing structure 3 can further include a second horizontal rod 32, and the part of the rod body of the second movable rod 31 close to the second end 312 is connected with the second horizontal rod 32, and the second horizontal rod 32 can contact with the second vertical rod. In this way, the second vertical rod can abut against the second horizontal rod 32 when the external force on the bearing plate 11 is removed, so as to drive the second movable rod 31 connected with the second horizontal rod 32 to rotate.

[0077] Specifically, when the second end 312 of the second movable rod 31 rotates towards the direction close to the first pressing structure 2, the second horizontal rod 32 also rotates towards the direction close to the first pressing structure 2, and at this time, the second horizontal rod 32 abuts against the second vertical rod, so that the second vertical rod also moves towards the direction close to the first pressing structure 2. When the second vertical rod moves away from the first pressing structure 2, it abuts against the second horizontal rod 32, so that the second horizontal rod 32 rotates away from the first pressing structure 2, and thus the second end 312 of the second movable rod 31 connected with the second horizontal rod 32 also rotates away from the first pressing structure 2.

[0078] In this case, when the sheet-shaped cloth mounting mechanism is in use, the load plate 11 is forced by the mounting object, and the load plate 11 moves towards the bottom of the shell 4 when it is subjected to external force. After the load plate 11 moves towards the bottom of the shell 4, it abuts against the first end 211 of the first movable rod 21 and the first end 311 of the second movable rod 31, and the first movable rod 21 and the second movable rod 31 rotate inwards. At this time, the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate towards each other, and the space between the first movable rod 21 and the second movable rod 31 becomes smaller. The second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 can press the sheet-shaped cloth close to the mounting object, i.e. mount the sheet-shaped cloth on the mounting object. At the same time, when the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate towards each other, the first cross rod 22 and the second cross rod 32 also rotate towards each other, and the first cross rod 22 and the second cross rod 32 abut against the first vertical rod and the second vertical rod respectively, so that the first vertical rod and the second vertical rod also move towards each other. After the sheet-shaped cloth is mounted on the mounting object, the load plate 11 is no longer forced by the mounting object. When the external force on the load plate 11 is removed, the first vertical rod and the second vertical rod move away from each other. When the first vertical rod and the second vertical rod move away from each other, the first cross rod 22 and the second cross rod 32 abut against the first vertical rod and the second vertical rod respectively, so that the first cross rod 22 and the second cross rod 32 rotate away from each other, and the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 also rotate away from each other, i.e. the first movable rod 21 and the second movable rod 31 rotate outwards. At this time, the space between the first movable rod 21 and the second movable rod 31 becomes larger, and the mounting object can be removed.

[0079] Optionally, referring to Figure 1 , the bearing structure 1 further comprises a first elastic member 14 and a third elastic member 16. The load plate 11 is movably connected to the first bearing member 12 through the first elastic member 14, and the load plate 11 is movably connected to the second bearing member 13 through the third elastic member 16.

[0080] The first elastic member 14 is a component with elasticity, which can make the first bearing member 12 have a restoring tendency. The first elastic member 14 can adopt various structural forms. For example, as Figure 1As shown, the first elastic member 14 can include a first pivot shaft 141 and a first torsion spring 142, the carrier plate 11 and the first carrier 12 are hinged through the first pivot shaft 141, the coil of the first torsion spring 142 is sleeved on the first pivot shaft 141, the first end of the first torsion spring 142 is fixed to the carrier plate 11, and the second end of the first torsion spring 142 abuts against the first carrier 12, so that the hinging of the carrier plate 11 and the first carrier 12 is realized through the first pivot shaft 141, and the first carrier 12 is reset through the first torsion spring 142. Alternatively, the first elastic member 14 can include a pivot shaft and a spring, the carrier plate 11 and the first carrier 12 are hinged through the pivot shaft, one end of the spring is connected to the carrier plate 11, and the other end of the spring is connected to the first carrier 12, so that the hinging of the carrier plate 11 and the first carrier 12 is realized through the pivot shaft, and the first carrier 12 is reset through the spring. Alternatively, the first elastic member 14 can include a pivot shaft and an elastic sheet, the elastic sheet can be a metal (copper, etc.) elastic sheet, the carrier plate 11 and the first carrier 12 are hinged through the pivot shaft, one end of the elastic sheet is connected to the carrier plate 11, and the other end of the elastic sheet is connected to the first carrier 12, so that the hinging of the carrier plate 11 and the first carrier 12 is realized through the pivot shaft, and the first carrier 12 is reset through the elastic sheet. Of course, the first elastic member 14 can also adopt other structural forms, and the embodiments of the present application do not limit this.

[0081] The third elastic member 16 is a component with elasticity, which can make the second carrier 13 have a reset tendency. The third elastic member 16 can adopt various structural forms. For example, as shown in the figure, Figure 1 As shown, the third elastic member 16 can include a second pivot shaft 161 and a second torsion spring 162, the carrier plate 11 and the second carrier 13 are hinged through the second pivot shaft 161, the coil of the second torsion spring 162 is sleeved on the second pivot shaft 161, the first end of the second torsion spring 162 is fixed to the carrier plate 11, and the second end of the second torsion spring 162 abuts against the second carrier 13, so that the hinging of the carrier plate 11 and the second carrier 13 is realized through the second pivot shaft 161, and the second carrier 13 is reset through the second torsion spring 162. Alternatively, the third elastic member 16 can include a pivot shaft and a spring, the carrier plate 11 and the second carrier 13 are hinged through the pivot shaft, one end of the spring is connected to the carrier plate 11, and the other end of the spring is connected to the second carrier 13, so that the hinging of the carrier plate 11 and the second carrier 13 is realized through the pivot shaft, and the second carrier 13 is reset through the spring. Alternatively, the third elastic member 16 can include a pivot shaft and an elastic sheet, the elastic sheet can be a metal (copper, etc.) elastic sheet, the carrier plate 11 and the second carrier 13 are hinged through the pivot shaft, one end of the elastic sheet is connected to the carrier plate 11, and the other end of the elastic sheet is connected to the second carrier 13, so that the hinging of the carrier plate 11 and the second carrier 13 is realized through the pivot shaft, and the second carrier 13 is reset through the elastic sheet. Of course, the third elastic member 16 can also adopt other structural forms, and the embodiments of the present application do not limit this.

[0082] When the second end 212 of the first movable rod 21 rotates towards the direction close to the second pressing structure 3, the first carrier 12 is driven to move towards the direction close to the second pressing structure 3 against the elastic force of the first elastic member 14. When the external force on the carrier plate 11 is removed, the first carrier 12 is driven by the first elastic member 14 to move towards the direction away from the second pressing structure 3 and then returns to its original position, so as to drive the second end 212 of the first movable rod 21 to rotate towards the direction away from the second pressing structure 3.

[0083] When the second end 312 of the second movable rod 31 rotates towards the direction close to the first pressing structure 2, the second carrier 13 is driven to move towards the direction close to the first pressing structure 2 against the elastic force of the first elastic member 14. When the external force on the carrier plate 11 is removed, the second carrier 13 is driven by the first elastic member 14 to move towards the direction away from the first pressing structure 2 and then returns to its original position, so as to drive the second end 312 of the second movable rod 31 to rotate towards the direction away from the first pressing structure 2.

[0084] In this case, when the sheet-shaped cloth mounting mechanism is in use, the carrier plate 11 is forced by the mounting object, and the carrier plate 11 moves towards the bottom of the shell 4 when it is subjected to the external force. After the carrier plate 11 moves towards the bottom of the shell 4, it stops against the first end 211 of the first movable rod 21 and the first end 311 of the second movable rod 31, so as to drive the first movable rod 21 and the second movable rod 31 to rotate towards the inside. At this time, the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate towards each other, and the space between the first movable rod 21 and the second movable rod 31 becomes smaller. The second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 can press the sheet-shaped cloth close to the mounting object, i.e. mount the sheet-shaped cloth on the mounting object. At the same time, when the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate towards each other, the first carrier 12 and the second carrier 13 are driven to move towards each other against the elastic force of the first elastic member 14 and the third elastic member 16 respectively. After the sheet-shaped cloth is mounted on the mounting object, the carrier plate 11 is no longer forced by the mounting object. When the external force on the carrier plate 11 is removed, the first carrier 12 and the second carrier 13 move away from each other under the action of the first elastic member 14 and the third elastic member 16 respectively, so as to drive the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 to rotate away from each other, i.e. the first movable rod 21 and the second movable rod 31 rotate towards the outside. At this time, the space between the first movable rod 21 and the second movable rod 31 becomes larger, so as to take out the mounting object.

[0085] In order to avoid the wobble of the bearing plate 11 during the movement, the sheet cloth mounting mechanism further comprises a guiding structure, and the following two possible guiding structures are described.

[0086] The first possible guiding structure, referring to Figure 1 , the bearing structure 1 further comprises a guiding rod 15, and the bottom of the shell 4 has a limiting hole. The guiding rod 15 is connected with the bearing plate 11, and the guiding rod 15 passes through the limiting hole; the guiding rod 15 can move in the limiting hole to guide the movement of the bearing plate 11.

[0087] The limiting hole can be a blind hole or a through hole, and the embodiments of the present application do not limit it. In the case of a blind hole, one end of the guiding rod 15 is connected to the bearing plate 11, the other end of the guiding rod 15 has a diameter smaller than the hole diameter of the limiting hole, and the other end of the guiding rod 15 is located in the limiting hole. The diameter of the rod body of the guiding rod 15 is smaller than the hole diameter of the limiting hole, so that the guiding rod 15 can move in the limiting hole. In the case of a through hole, one end of the guiding rod 15 is connected to the bearing plate 11, the other end of the guiding rod 15 has a diameter larger than the hole diameter of the limiting hole, and the other end of the guiding rod 15 is clamped outside the shell 4 after passing through the limiting hole. The diameter of the rod body of the guiding rod 15 is smaller than the hole diameter of the limiting hole, so that the guiding rod 15 can move in the limiting hole.

[0088] In this case, when the bearing plate 11 moves towards the bottom of the shell 4, the guiding rod 15 connected to the bearing plate 11 passes through the limiting hole in the bottom of the shell 4, so the guiding rod 15 moves along the limiting hole, which makes the bearing plate 11 move along the axial direction of the limiting hole towards the bottom of the shell 4. Similarly, when the bearing plate 11 moves away from the bottom of the shell 4, the guiding rod 15 connected to the bearing plate 11 passes through the limiting hole in the bottom of the shell 4, so the guiding rod 15 moves along the limiting hole, which makes the bearing plate 11 move along the axial direction of the limiting hole away from the bottom of the shell 4. In this way, through the guiding rod 15, the bearing plate 11 can always move along the axial direction of the limiting hole during the movement, without wobbling, thereby playing a guiding role during the movement of the bearing plate 11.

[0089] The second possible guiding structure, the side wall of the shell 4 has a first sliding structure, and the bearing structure 1 further comprises a second sliding structure. The bearing plate 11 is connected with the second sliding structure, and the second sliding structure is in sliding cooperation with the first sliding structure to guide the movement of the bearing plate 11.

[0090] The second sliding structure and the first sliding structure are two components that can realize sliding cooperation. In this way, when the second sliding structure moves, it slides along the first sliding structure, which makes the bearing plate 11 connected with the second sliding structure slide along the axial direction of the first sliding structure.

[0091] The first sliding structure and the second sliding structure can adopt various structural forms. For example, the first sliding structure can be a strip-shaped groove, and the second sliding structure can be a sliding block which is in sliding cooperation with the strip-shaped groove. In this case, the strip-shaped groove can also limit the sliding block in the depth direction of the groove to avoid the sliding block from being taken out of the strip-shaped groove, for example, the strip-shaped groove and the sliding block can both be T-shaped. Alternatively, the first sliding structure can be a strip-shaped protrusion, and the second sliding structure can be a sliding groove which is in sliding cooperation with the strip-shaped protrusion. In this case, the sliding groove can also limit the strip-shaped protrusion in the depth direction of the groove to avoid the strip-shaped protrusion from being taken out of the sliding groove, for example, the strip-shaped protrusion and the sliding groove can both be T-shaped. Of course, the first sliding structure and the second sliding structure can also adopt other structural forms, which are not limited in the embodiments of the present application.

[0092] In this case, when the bearing plate 11 moves towards the bottom of the shell 4, the second sliding structure connected with the bearing plate 11 will slide along the first sliding structure on the side wall of the shell 4 due to the sliding cooperation between the second sliding structure and the first sliding structure, so that the bearing plate 11 slides along the axial direction of the first sliding structure towards the bottom of the shell 4. Similarly, when the bearing plate 11 moves away from the bottom of the shell 4, the second sliding structure connected with the bearing plate 11 will slide along the first sliding structure on the side wall of the shell 4 due to the sliding cooperation between the second sliding structure and the first sliding structure, so that the bearing plate 11 slides along the axial direction of the first sliding structure away from the bottom of the shell 4. In this way, the bearing plate 11 can always slide along the axial direction of the first sliding structure when moving through the second sliding structure, and will not shake, thereby playing a guiding role when the bearing plate 11 moves.

[0093] Optionally, referring to Figure 1 The sheet-shaped cloth mounting mechanism further comprises a second elastic member 5 which is connected below the bearing structure 1, i.e., between the bearing structure 1 and the bottom of the shell 4. The second elastic member 5 is a component with elasticity and can make the bearing plate 11 have a restoring tendency. In this case, the second elastic member 5 can be connected below the bearing plate 11. Specifically, the second elastic member 5 can be connected between the bearing plate 11 and the bottom of the shell 4, or the second elastic member 5 can be connected between the component connected with the bearing plate 11 in the bearing structure 1 and the bottom of the shell 4.

[0094] The second elastic member 5 can adopt various structural forms. For example, as shown in Figure 1As shown, the second elastic member 5 can be a spring, one end of the spring can be connected to the bearing structure 1, and the other end of the spring can be connected to the bottom of the shell 4. Alternatively, the second elastic member 5 can be an elastic sheet such as a metal (copper, etc.) elastic sheet, one end of the elastic sheet can be connected to the bearing structure 1, and the other end of the elastic sheet can be connected to the bottom of the shell 4. Alternatively, the second elastic member 5 can be a combination mechanism of a rotating shaft and a torsion spring, the rotating shaft is connected to the shell 4, the coil of the torsion spring is sleeved on the rotating shaft, one of the two free ends of the torsion spring is overlapped on the bearing structure 1, and the other free end is overlapped on the bottom of the shell 4. Of course, the second elastic member 5 can also adopt other structural forms, and the embodiments of the present application do not limit this.

[0095] For example, in the first possible guiding structure described above, referring to Figure 1 In the case where the second elastic member 5 is a spring, the diameter of the spring can be greater than the diameter of the guiding rod 15 and greater than the hole diameter of the limiting hole, the spring can be sleeved on the rod body of the guiding rod 15 at a position between the bearing plate 11 and the limiting hole, at this time, one end of the spring is in abutment with the bearing plate 11, and the other end of the spring is in abutment with the bottom of the shell 4, so that the bearing plate 11 in abutment with one end of the spring has a restoring tendency.

[0096] For example, in the second possible guiding structure described above, the second elastic member 5 can not be connected between the bearing plate 11 and the bottom of the shell 4, but can be connected between the second sliding structure and the bottom of the shell 4, in this way, the bearing plate 11 connected with the second sliding structure has a restoring tendency.

[0097] In this case, when the sheet-shaped cloth mounting mechanism is in use, the bearing plate 11 is moved downward (i.e. in the direction close to the bottom of the shell 4) against the elastic force of the second elastic member 5 under the external force applied by the installation object, and after the bearing plate 11 is moved in the direction close to the bottom of the shell 4, the bearing plate 11 abuts against the first pressing structure 2 and the second pressing structure 3, so that the first pressing structure 2 and the second pressing structure 3 are rotated in the direction close to each other, at this time, the space between the first pressing structure 2 and the second pressing structure 3 is smaller, so that the sheet-shaped cloth can be pressed close to the installation object, i.e. the sheet-shaped cloth is mounted on the installation object. After the sheet-shaped cloth is mounted on the installation object, the bearing plate 11 is no longer subjected to the external force applied by the installation object. When the external force is removed, the bearing plate 11 is moved upward (i.e. in the direction away from the bottom of the shell 4) under the action of the second elastic member 5 and then returns to the original position.

[0098] Next, the overall use process of the sheet-shaped cloth mounting mechanism will be illustrated by taking the sheet-shaped cloth mounting mechanism shown in Figure 2 , Figure 3 and Figure 4 as an example.

[0099] The sheet cloth mounting mechanism, before use, places the sheet cloth into the space between the first movable rod 21, the first horizontal rod 22, the second movable rod 31 and the second horizontal rod 32, that is, into the space between the first vertical rod and the second vertical rod, that is, onto the bearing plate 11. The sheet cloth mounting mechanism, when in use, first places the mounting object into the space between the first movable rod 21, the first horizontal rod 22, the second movable rod 31 and the second horizontal rod 32, that is, into the space between the first vertical rod and the second vertical rod, that is, into the position where the bearing plate 11 is located. Then, by the mounting object applying force to the bearing plate 11, the bearing plate 11, when subjected to external force, overcomes the elastic force of the second elastic member 5 and moves along the axial direction of the limiting hole at the bottom of the shell 4 (that is, under the guidance of the limiting hole), that is, towards the bottom of the shell 4, and after the bearing plate 11 moves towards the bottom of the shell 4, it abuts against the first end 211 of the first movable rod 21 and the first end 311 of the second movable rod 31, causing the first movable rod 21 and the second movable rod 31 to rotate towards the inside, at which time the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate towards each other, the space between the first movable rod 21 and the second movable rod 31 becomes smaller, and the first pressing plate 23 hinged to the second end 212 of the first movable rod 21 and the second pressing plate 33 hinged to the second end 312 of the second movable rod 31 can press the sheet cloth close to the mounting object, that is, mount the sheet cloth onto the mounting object. At the same time, when the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate towards each other, the first horizontal rod 22 and the second horizontal rod 32 also rotate towards each other, and when the first horizontal rod 22 and the second horizontal rod 32 rotate towards each other, they abut against the first vertical rod and the second vertical rod respectively, causing the first vertical rod and the second vertical rod to move towards each other respectively, overcoming the elastic force of the first elastic member 14 and the third elastic member 16.

[0100] After the sheet fabric is installed onto the mounting object, no force is applied to the support plate 11 through the mounting object. When the external force on the support plate 11 is removed, the first and second vertical rods move away from each other under the action of the first elastic element 14 and the third elastic element 16. When the first and second vertical rods move away from each other, they respectively abut against the first horizontal rod 22 and the second horizontal rod 32, causing the first horizontal rod 22 and the second horizontal rod 32 to rotate away from each other. As a result, the second ends 212 of the first movable rod 21 and the second ends 312 of the second movable rod 31 also rotate away from each other, that is, the first movable rod 21 and the second movable rod 31 rotate outward. At this time, the space between the first movable rod 21, the first horizontal rod 22, the second movable rod 31 and the second horizontal rod 32, that is, the space between the first vertical rod and the second vertical rod, becomes larger, and the mounting object can be removed. After removing the mounting object, the sheet fabric installed on the mounting object can be used. In addition, when the second end 212 of the first movable rod 21 and the second end 312 of the second movable rod 31 rotate away from each other, the first end 211 of the first movable rod 21 and the first end 311 of the second movable rod 31 abut against the bearing plate 11, causing the bearing plate 11 to move away from the bottom of the housing 4 along the axial direction of the limiting hole at the bottom of the housing 4 (i.e., under the guidance of the limiting hole). At the same time, when the external force is removed, the bearing plate 11 will also move away from the bottom of the housing 4 along the axial direction of the limiting hole under the action of the second elastic member 5 and then reset.
