Description
Technical Field
[0001] This utility model relates to the field of toilet technology, and in particular to a portable toilet that can be stretched and unfolded vertically. Background Technology
[0002] Toilets are generally considered an indispensable indoor hygiene tool in people's daily lives, and are suitable for fixed installation and use indoors.
[0003] However, people also need toilets when they are out and about, traveling, or engaging in outdoor activities, which creates a demand for portable, foldable toilets.
[0004] When unfolding a foldable toilet from its folded state to its usable state, one needs to reach inside the toilet bowl and push the connecting joints of the support legs from the inside out until the two support legs are perpendicular, making the whole structure an elliptical cylinder, thus completing the installation and use. Although there is a plastic bag to protect the toilet during excretion, it is still inevitable to feel psychologically uncomfortable to directly reach inside the toilet bowl to operate it.
[0005] Therefore, there is a need to provide a portable toilet that can be extended and unfolded vertically to solve the above-mentioned technical problems. Utility Model Content
[0006] The main technical problem solved by this utility model is to provide a portable toilet that can be stretched and unfolded vertically, which solves the problem that existing folding toilets need to be unfolded from the inside.
[0007] To solve the above-mentioned technical problems, one technical solution adopted by this utility model is to provide a portable toilet that can be stretched and unfolded vertically, including a lid 1, a bottom 3, and a body 2 connecting the lid 1 and the bottom 3; the body 2 includes a plurality of shells 21 that are connected in sequence and whose radius increases sequentially from the lid 1 to the bottom 3. Each shell 21 is provided with a pin 22 that locks it to the next shell 21 or to the adjacent bottom 3 when the body 2 is stretched. The lid 1 is provided with a first unlocking member 11 for unlocking the pin 22 on the top shell 21 as it rotates. Each shell 21 is provided with a second unlocking member 23 for unlocking the pin 22 of the next layer when it is pressed down.
[0008] In one embodiment, anti-slip buckles 24 are provided on the two adjacent shells 21 and on the bottom shell 21 and the bottom of the barrel 3.
[0009] In one embodiment, the shell 21 is integrally formed with a vertical groove 25 that is concave on the outside and convex on the inside. The inner side wall of the bottom of the barrel 3 is provided with a vertical protrusion 31. The vertical protrusion 31 and the vertical groove 25 are respectively provided with the buckle 24. The vertical protrusion 31 and the vertical groove 25 are respectively slidably disposed in the vertical groove 25 of their respective upper layer and are prevented from slipping by the mutually matching buckle 24.
[0010] In one embodiment, when the barrel 2 is unfolded, the free end of the pin 22 is inserted into the shell 21 of the next layer or into the pin hole 26 provided on the side wall of the barrel bottom 3 adjacent to it.
[0011] In one embodiment, the second unlocking member 23 includes two mutually spaced vertical wedges 231 integrally formed on the corresponding housing 21. When the barrel 2 is subjected to sufficiently strong pressure in the direction from the barrel lid 1 to the barrel bottom 3, the vertical wedges 231 push the pin 22 out of the corresponding pin hole 26.
[0012] In one embodiment, the pin 22 includes a fixing seat 221, an end cap 222, a pin body 223, and a first spring 224 that limits the pin body 223 between the fixing seat 221 and the end cap 222. The fixing seat 221 is screwed to the corresponding housing 21, and the end cap 222 is screwed to the fixing seat 221. When the pin 22 is unlocked, the vertical wedge 231 presses down and pushes the pin body 223 toward the end cap 222 to squeeze the first spring 224, so that the pin body 223 disengages from the corresponding pin hole 26.
[0013] In one embodiment, the pin body 223 includes a central seat 2231 connected to one end of the first spring 224, a tongue 2232 integrally formed on the bottom of the central seat 2231, and extension posts 2233 formed on both sides of the central seat 2231. During the process of the vertical wedge 231 pressing down on the corresponding pin body 223, the extension posts 2233 are pushed to move toward the end cap 222, causing the tongue 2232 to disengage from the corresponding pin hole 26. During the process of the bucket cap 1 and the bucket bottom 3 being stretched in opposite directions, the vertical wedge 231 moves up to release the pressure on the extension posts 2233, and the first spring 224 presses the tongue 2232 into the corresponding pin hole 26.
[0014] In one embodiment, counting from the lid 1 to the bottom 3, the shell 21 above the vertical wedge 231 on the even-numbered shell layer 21 is provided with a first clearance opening 27 for avoiding the vertical wedge 231, and the top of the third shell layer 21 is provided with a second clearance opening 28 for avoiding the tongue 2232 on the first shell layer 21.
[0015] In one embodiment, the lid 1 includes a top cover 12, a middle cover 13 with a garbage inlet for pressing down the garbage bag opening, a bottom cover 14 for unlocking a pin 22 on the top cover housing 21, a handle 15, and a pin 16; the pin 16 rotatably connects the top cover 12, the middle cover 13, the bottom cover 14, and the handle 15.
[0016] In one embodiment, the bottom cover 14 is integrally formed with a plurality of spaced-apart strip holes 141. The threaded ends of a plurality of limiting rollers 17 pass through the corresponding strip holes 141 and are screwed to the top shell 21. The first unlocking member 11 includes: a U-shaped wedge 111 with a downward U-shaped opening slidably disposed on the inner wall of the top shell 21; a slide rail 112 guiding the lower end of the U-shaped wedge 111 to slide along a straight direction; a second spring 114 connecting the inner bottom surface of the U-shaped wedge 111 and the corresponding pin 22; and a transverse wedge 113 provided on the bottom cover 14. When the bucket cover 1 is rotated to unlock, the transverse wedge 113 presses down on the U-shaped wedge 111 to push the pin 22 on the top shell 21 to unlock. When the bucket body 2 is unfolded and locked, the bucket cover 1 is rotated in the opposite direction, the transverse wedge 113 releases the pressure on the U-shaped wedge 111, and the second spring 114 pushes the U-shaped wedge 111 up to lock the bottom cover 14.

[0028] The technical solution of this utility model will be described in detail below with reference to the illustrations.
[0029] Please see Figures 1-4 As shown, the portable toilet that can be stretched up and down in this embodiment includes a lid 1, a bottom 3, and a body 2 connecting the lid 1 and the bottom 3. The body 2 includes a plurality of shells 21 that are connected in sequence and whose radii increase in sequence along the direction from the lid 1 to the bottom 3, so that when the lid 1 is pressed down to complete the folding of the body 2, the plurality of shells are folded into the bottom 3 in sequence.
[0030] The housing 21 is provided with a pin 22 that locks it to the next housing 21 or to the adjacent bottom 3 when the bucket body 2 is stretched. The lid 1 is provided with a first unlocking member 11 (unmarked) for unlocking the pin 22 on the top housing 21 as it rotates. Each housing 21 is provided with a second unlocking member 23 for unlocking the pin 22 of the next layer when it is pressed down. It can be seen that rotating the lid and pressing down the lid 1 can realize the folding and storage of the toilet, making it convenient for users to carry.
[0031] To prevent the toilet bowl 2 from opening during the toilet's unfolding and locking process, anti-slip buckles 24 are provided on the two adjacent shells 21 and on the bottom shell 21 and the bottom of the bowl 3. Figures 4-6 As shown.
[0032] like Figure 2 , Figures 4-6 As shown, to further prevent slippage between the shells 21 and between the shell 21 and the bottom 3, the shell 21 is integrally formed with a vertical groove 25 that is concave on the outside and convex on the inside. The inner sidewall of the bottom 3 is provided with a vertical rib 31. The vertical rib 31 and the vertical groove 25 are respectively provided with the aforementioned buckles 24. The vertical rib 31 and the vertical groove 25 are slidably disposed in the vertical groove 25 above them and are prevented from slipping by the mutually matching buckles 24. In this way, slippage between the shells can be prevented, and the purpose of stable unfolding of the barrel 2 can be achieved.
[0033] In specific applications, when the bucket 2 is unfolded, such as Figure 6 As shown, the free end of the pin 22 is inserted into the pin hole 26 provided on the shell 21 of the next layer or on the side wall of the barrel bottom 3 adjacent to it, so as to complete the unfolding and locking of the barrel body 2.
[0034] like Figure 4As shown, in one embodiment, the second unlocking member 23 includes two mutually spaced vertical wedges 231 integrally formed on the corresponding housing 21. When the barrel 2 is subjected to sufficiently strong pressure from the barrel lid 1 to the barrel bottom 3, the vertical wedges 231 gradually push the pin 22 out of the corresponding pin hole 26, thereby unlocking the barrel 2 and enabling the barrel 2 to be folded smoothly.
[0035] For detailed information on the structure of pin 22, please refer to [reference needed]. Figure 7 and Figure 8 As shown, the pin 22 includes a fixing seat 221, an end cap 222, a pin body 223, and a first spring 224 that limits the pin body 223 between the fixing seat 221 and the end cap 222. The fixing seat 221 is screwed to the corresponding housing 21, and the end cap 222 is screwed to the fixing seat 221. When the pin 22 is unlocked, the vertical wedge 231 presses down to push the pin body 223 toward the end cap 222 to squeeze the first spring 224, and pulls the pin body 223 out of the corresponding pin hole 26.
[0036] For a more detailed description of the pin body 223, please refer to [reference needed]. Figure 8 As shown, the latch body 223 includes a central seat 2231 connected to one end of the first spring 224, a latch tongue 2232 integrally formed at the bottom of the central seat 2231, and extension posts 2233 formed at both ends of the central seat 2231. During the downward pressing of the vertical wedge 231 onto the corresponding latch body 223, it directly contacts and pushes the extension posts 2233 toward the end cap 222. Under the tension of the first spring 224, the latch tongue 2232 disengages from the corresponding latch hole 26. During the back-to-back stretching of the lid 1 and the bottom 3, the vertical wedge 231 moves upward, gradually reducing the pressure on the extension posts 2233. Under the elastic restoring force, the first spring 224 gradually pushes and compresses the latch tongue 2232 into the corresponding latch hole 26, completing the locking of the latch 22, i.e., locking the unfolded toilet body 2. In this state, the user can squat and use the toilet.
[0037] like Figure 5 As shown, in order to achieve smooth folding and unlocking of each layer, counting from the lid 1 to the bottom 3, the shell 21 of the even-numbered layer 21 is provided with a first clearance opening 27 for avoiding the vertical wedge 231 on the next layer, as shown. Figure 2 As shown, the top of the third shell 21 is provided with a second clearance opening 28 to avoid the tongue 2232 on the first shell 21. This allows for a more complete folding of the barrel 2.
[0038] For the specific structure of the rotatable bucket lid 1, please refer to... Figure 2 and Figure 3As shown, in one embodiment, the toilet lid 1 includes a top cover 12, a middle cover 13 with a garbage inlet for pressing down the opening of a garbage bag, a bottom cover 14 for unlocking a pin 22 on the top housing 21, a handle 15, and a pin 16; the pin 16 rotatably connects the top cover 12, the middle cover 13, the bottom cover 14, and the handle 15. In use, the user first rotates to open the top cover 12 and the middle cover 14, then puts the garbage bag into the toilet body 2. The top opening of the garbage bag is then pressed against the bottom cover 14 by the middle cover 14, thereby stabilizing the top opening of the garbage bag and preventing it from falling into the toilet body 2. The user can then sit on the middle cover 14 to use the toilet. The handle 15 can also be used to easily retrieve the toilet in its unfolded or folded state.
[0039] In one embodiment, such as Figure 2 and Figure 3 As shown, the bottom cover 14 is integrally formed with multiple spaced-apart strip-shaped holes 141 around its circumference. Multiple limiting rollers 17, with their threaded ends passing through corresponding strip-shaped holes 141, are screwed onto the top shell 21. Figure 3 and Figure 4 As shown, the first unlocking component 11 includes: a U-shaped wedge 111 with a downward U-shaped opening slidably disposed on the inner wall of the top shell 21; a slide rail 112 guiding the lower end of the U-shaped wedge 111 to slide along a straight direction; a second spring 114 connecting the inner bottom surface of the U-shaped wedge 111 and the corresponding pin 22; and a transverse wedge 113 provided on the bottom cover 14. When the bucket lid 1 is rotated to unlock, the transverse wedge 113 presses down on the U-shaped wedge 111 to push the pin 22 on the top shell 21 to unlock. When the bucket body 2 is unfolded and locked, the bucket lid 1 is rotated in the opposite direction, the transverse wedge 113 releases the pressure on the U-shaped wedge 111, and the second spring 114 pushes the U-shaped wedge 111 up to block the bottom cover 14 and locks it.
