In the direction of the rotation of the handrail 200, the plug portion 321 has two locking surfaces which are opposite to each other, and the locking slot 311 has two side wall surfaces which are opposite to each other. The locking surfaces are capable of being abutted against the side wall surfaces to limit the rotation of the handrail 200 relative to the fixing base 100. In the opening direction of the plug interface 312, the distance between the two side wall surfaces gradually decreases. Therefore, when the plug 410 is separated from the second locking member 320, in the process of rotating the handrail 200, the side wall surfaces are capable of exerting a separation force on the plug portion 321 which is away from the locking slot 311, so that the plug portion 321 is automatically moved to the outside of the locking slot 311 to release the locking between the first locking member 310 and the second locking member 320, without the need for additional operation steps, so that the safety handrail of the present embodiment is more convenient to use.

[0064] Similarly, in some embodiments, in the direction of the plug portion 321 extending into the locking slot 311, the distance between the two locking surfaces gradually decreases. The working principle is the same as above, which will not be described here again.

[0065] With reference to Figure 4 In some embodiments, the first locking member 310 has a first circular arc surface 313, and the first locking member 310 has a plurality of locking slots 311 which are spaced apart from each other at the first circular arc surface 313 to form a plurality of plug interfaces 312. The plug portion 321 is capable of being plugged into different locking slots 311, so that the handrail 200 can be locked at different positions of the fixing base 100. Therefore, the user can adjust the position of the handrail 200 according to the needs, so as to improve the practicability of the handrail 200. For example, when the user has a larger body shape or needs a larger amplitude of forward leaning, the user can adjust the handrail 200 to a position which is farther away from the toilet 700 according to the needs, and vice versa.

[0066] In addition, when the user needs to stand up, the handrail 200 can be adjusted to a position which is closer to the main body of the toilet 700, so that the user can stand up with the support of the handrail 200. For example, when the handrail 200 is across in front of the user, the user normally defecates by crouching on the handrail 200. When the user needs to stand up, the handrail 200 is rotated towards the user by a certain angle (such as 45°), so that the user can be supported by the handrail 200 in the process of standing up, so that the practicability of the safety handrail of the present embodiment is higher.

[0067] With reference to Figure 4 and Figure 8 , Figure 8 for Figure 3The structure diagram of the second locking member is shown in FIG. 6. Based on the above embodiment, the second locking member 320 has a second arc surface 322 on the side facing the first locking member 310, which is matched with the first arc surface 313. A plurality of insertion portions 321 are arranged at intervals on the second arc surface 322, so that the first locking member 310 and the second locking member 320 can be connected through the cooperation of the plurality of insertion portions 321 and the plurality of locking grooves 311, thereby improving the stability of the handrail 200 during locking and the safety of the safety handrail during use. In addition, it can be understood that, since the first locking member 310 and the second locking member 320 are simultaneously cooperated through the plurality of insertion portions 321 and the plurality of locking grooves 311, the pressure on each insertion portion 321 is reduced, thereby reducing the wear between the first locking member 310 and the second locking member 320, and prolonging the service life of the safety handrail.

[0068] Referring to Figure 4 In some embodiments, the locking device 300 further comprises a second elastic member 330 connected to the second locking member 320, which can rotate the second locking member 320 towards the first locking member 310. For example, one end of the second elastic member 330 is connected to the second locking member 320, and the other end is connected to the handrail 200, but not limited thereto, as long as the second locking member 320 can be rotated towards the second locking member 320 under the elastic force of the second elastic member 330. Specifically, for example, the second elastic member 330 is a compression spring, one end of which is connected to the handrail 200, and the other end is connected to the side of the second locking member 320 away from the first locking member 310. During use, when it is necessary to rotate the handrail 200, the bolt 410 is first driven to the second position to release the locking of the position of the second locking member 320, and then a pushing force is applied to the handrail 200, which is transmitted to the second locking member 320. The second locking member 320 is rotated relative to the handrail 200 under the resistance of the side wall surface of the locking groove 311, away from the first locking member 310 and pressing the second elastic member 330. The second elastic member 330 applies a pushing force to the second locking member 320 towards the first locking member 310. At the same time, the second locking member 320 rotates along the circumference of the first arc surface 313 with the handrail 200. When the insertion portion 321 on the second locking member 320 is rotated from one locking groove 311 to the position of the adjacent other locking groove 311, the second locking member 320 is rotated relative to the handrail 200 under the elastic force of the second elastic member 330 to face the first locking member 310, so that the insertion portion 321 of the second locking member 320 extends into the locking groove 311 of the first locking member 310, thereby providing a sense of jerk to the user when rotating the handrail 200, and improving the user experience.

[0069] Referring to Figure 8 and Figure 9 , Figure 9In some embodiments, the second locking member 320 comprises a locking portion 323 and an abutting portion 324. The locking portion 323 has a second arc surface 322. The locking portion 323 has a first connecting portion 3231 which is rotationally connected to the handrail 200. The abutting portion 324 is connected to a surface of the locking portion 323 opposite to the second arc surface 322. The side of the locking portion 323 close to the first connecting portion has a first abutting surface 3241. The latch 410 has a second abutting surface 411. The angle between the second abutting surface 411 and the moving direction of the latch 410 is a, and 0≤a≤5°. When the latch 410 is in the first position, the second abutting surface 411 abuts against the first abutting surface 3241 to limit the rotation of the second locking member 320, so that the locking portion 323 remains in the state of abutting against the first locking member 310. When the locking portion 323 abuts against the first locking member 310, the angle between the first abutting surface 3241 and the moving direction of the latch 410 is β, and 0≤β≤5°. Specifically, it can be understood that when the latch 410 is in the first position, the second locking member 320 exerts a reaction force on the latch 410 while the latch 410 limits the rotation of the second locking member 320. Since the angle between the first abutting surface 3241 and the moving direction of the latch 410 is 0-5°, the angle between the force exerted by the first abutting surface 3241 on the second abutting surface 411 and the moving direction of the latch 410 is 85-90°. That is, in the locked state, the pushing direction of the latch 410 by the first locking member 310 tends to be perpendicular to the moving direction of the latch 410, thereby preventing the latch 410 from moving away from the second locking member 320 (moving towards the second position) under the pushing force of the second locking member 320, so as to ensure that the latch 410 remains in the first position to abut against the second locking member 320, thereby ensuring that the first locking member 310 and the second locking member 320 are always in the locked state, and further ensuring that the handrail 200 is locked to improve the safety of the safety handrail.

[0070] It can be understood that, through the design of the present embodiment, the latch 410 can be abutted in the first position when the first elastic member 420 has a small elastic potential, thereby reducing the selection requirements of the first elastic member 420 and the selection cost of the first elastic member 420. In addition, since the latch 410 can be abutted in the first position when the first elastic member 420 has a small elastic potential, the user can drive the latch 410 to the second position with a smaller force in the use process, thereby making the use of the safety handrail of the present embodiment more convenient.

[0071] Referring to Figure 8 and Figure 9 On the basis of the above embodiments, the abutting portion 324 protrudes from the locking portion 323 along the axial direction of the second arc surface 322. The locking device 300 comprises two second locking members 320 (as shown in Figure 7As shown in FIG. 6, the two second locking members 320 are distributed along the axial direction of the first circular surface 313, wherein the locking portion 323 of any one of the second locking members 320 extends to the surface of the locking portion 323 of the other second locking member 320 which is opposite to the second circular surface 322, and along the circumferential direction of the first circular surface 313, wherein the abutting portion 324 of any one of the second locking members 320 is located between the first connecting portion 3231 and the abutting portion 324 of the other second locking member 320 (as shown in FIG. 6). Figure 9 As shown in FIG. 6, when the two second locking members 320 are abutted to the first locking member 310, the first abutting surface 3241 of the two abutting portions 324 defines the clamping gap 340. The latch 410 has two second abutting surfaces 411 which are oppositely arranged, when the latch 410 is located at the first position, the latch 410 is inserted into the clamping gap 340, and the two second abutting surfaces 411 abut to the two first abutting surfaces 3241 respectively. Therefore, during use, the two second abutting portions 324 apply symmetrical pushing force to the latch 410, avoiding the bending moment of the latch 410, thereby preventing the latch 410 from being deformed and bent, avoiding the latch 410 from being unable to move due to too much deformation, thereby improving the reliability of the latch 410, and further improving the safety of the safety handrail in the embodiment during use.

[0072] In addition, it should be noted that the second elastic member 330 can rotate the second locking member 320 towards the first locking member 310 as described above, therefore, when the locking device 300 includes two second locking members 320, the second elastic member 330 can move the two abutting portions 324 away to form the clamping gap during driving the second locking member 320 towards the first locking member 310. Therefore, when the locking device 300 includes two second locking members 320, the second elastic member 330 also has the effect of automatically forming the clamping gap 340 between the two abutting portions 324, thereby ensuring that the latch 410 can move to the first position to abut to the two first abutting surfaces 3241 to achieve the locking of the position of the handrail 200, thereby improving the safety of the safety handrail in the embodiment during use.

[0073] Referring to Figure 8In some embodiments, the second locking member 320 further comprises an extension 325 connected to the locking portion 323, the second arc surface 322 extends to the extension 325, and the extension 325 is spaced apart from the abutting portion 324 along the circumferential direction of the second arc surface 322. Specifically, in the present embodiment, by arranging the extension 325, the area of the second arc surface 322 can be increased, thereby increasing the size of the insertion portion 321, increasing the contact area between the first locking member 310 and the second locking member 320, reducing the pressure intensity on the first locking member 310 and the second locking member 320, reducing the wear between the first locking member 310 and the second locking member 320, and prolonging the service life of the safety handrail of the present embodiment. It should be noted that the dashed line in the above

[0074] It should be noted that the dashed line in the above Figure 8 cannot be interpreted as the contour line in the second locking member 320, but only serves to clearly distinguish the extension 325 from the locking portion 323, so as to clearly describe the structure of the second locking member 320.

[0075] Based on the above embodiments, the size of the extension 325 is equal to the size of the locking portion 323 along the axial direction of the second arc surface 322. Therefore, after the two second locking members 320 are assembled, the two surfaces of the two second locking members 320 that are arranged opposite to each other along the axial direction of the second arc surface 322 are flush. Therefore, when the two second locking members 320 are rotatably connected to the handrail 200 by the pin shaft, the two second locking members 320 can be in sliding abutment with the surface of the handrail 200, thereby improving the stability of the second locking member 320.

[0076] Referring to Figure 4 In some embodiments, the second elastic member 330 is connected to the two second locking members 320 at two ends thereof, respectively, for moving the two abutting portions 324 away from each other, thereby moving the two second locking members 320 towards the first locking member 310. For example, the second elastic member 330 is a compression spring, and the two ends of the compression spring are connected to the two abutting portions 324, respectively. Alternatively, the second elastic member is a tension spring, and the two ends of the tension spring are connected to the two second locking members, and at least one of the two ends of the tension spring is located outside the two abutting portions 324 along the circumferential direction of the first arc surface 313 (as shown in FIG. 6). Figure 4As shown in the figure, the second elastic member 330 is a V-shaped spring, both ends of the V-shaped spring are located outside the two abutting portions 324, and a pulling force is applied to the two second locking members 320 to make the two abutting portions 324 move away from each other. It can be understood that in the embodiment, the two second locking members 320 are rotated towards the first locking member 310 and abut against the first locking member 310 by one second elastic member 330, and each second locking member 320 does not need to be separately connected with one second elastic member 330, which reduces the manufacturing cost of the safety handrail of the embodiment and improves the assembly efficiency.

[0077] Referring to Figure 12 , Figure 12 The structure diagram of the toilet assembly of the second aspect embodiment of the application is shown. The toilet assembly of the second aspect embodiment includes a toilet 700 and the safety handrail of the first aspect embodiment. The fixed seat 100 is connected to the wall beside the toilet 700 or connected to the toilet 700. The handrail 200 can be rotated to a set position of the toilet 700 for supporting the user. For example, the fixed seat 100 is connected to the wall. When the user does not need to use the handrail 200, the handrail 200 can be rotated to a storage state of abutting against the wall. When the user needs to be supported by leaning forward, the handrail 200 is rotated to the front end of the toilet 700, and the position of the handrail 200 is locked by the locking device 300 for supporting the user. The limiting device 400 of the safety handrail includes the second locking member 320 and the latch 410. The second locking member 320 is movably connected to the handrail 200. The latch 410 is movably connected to the handrail 200 and can abut against the second locking member 320, so that the second locking member 320 abuts against the first locking member 310 to limit the rotation of the handrail 200 relative to the fixed seat 100. Therefore, compared with the prior art, the latch 410 in the embodiment only needs to be moved to the first position to abut against the second locking member 320, without the need of closely matching the latch 410 with the connecting structure on the handrail, so as to reduce the processing requirement of the safety handrail, thereby reducing the manufacturing cost of the toilet assembly. In addition, even if the latch 410 is deformed to a certain extent, the latch 410 can still be smoothly moved, improving the reliability of the latch 410 and the safety of the toilet assembly of the embodiment in use.

[0078] It should be noted that the toilet assembly of the embodiment adopts all the technical solutions of the first aspect embodiment, and at least has all the beneficial effects brought by the technical solutions of the first aspect embodiment, which will not be repeated here.

[0079] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the application.
