Description

Technical Field

[0001] The invention relates to the technical field of marine toilets, in particular to a movable backrest reinforcement frame structure of a wall-mounted toilet. Background Art

[0002] Conventional wall-mounted toilets in marine bathrooms typically cannot be directly fixed to the interior wall panels. This is because the single-point force applied to the toilet's fixing bolts can easily damage the interior panels. Therefore, reinforcements are usually pre-embedded in the interior decorative back panel. The wall-mounted toilet's fixing bolts are then passed through the interior decorative back panel and fixed to the pre-embedded parts according to the position of the pre-embedded parts. This original design has many limitations: 1) If the interior decorative back panel lacks pre-embedded reinforcements, the toilet's mounting structure cannot be installed; 2) Once installed, the toilet's height is fixed, making it inconvenient for people of different heights (especially children). Changing the height requires cutting and shifting, which is time-consuming, labor-intensive, and has a significant impact.

[0003] Chinese invention patent application number CN202210456209.3 discloses an assembled design structure for a wall-mounted toilet with an adjustment function. Although the toilet has the function of being able to be raised and lowered, it is fixed by a fixing bracket in the wall, and there is space between the fixing bracket and the wall to set the drive motor. Therefore, a sufficiently thick wall is required for installation, which makes it unsuitable for installation in a ship hull. In addition, the toilet is raised and lowered by a longitudinally arranged spiral lifter, but when the toilet end is loaded, the force acting on the spiral lifter can easily cause the spiral lifter to deflect, thereby reducing the stability of the toilet. Secondly, its lifting must be controlled electrically, which has a high failure rate. In view of the above, we propose a movable backrest reinforcement frame structure for a wall-mounted toilet to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a wall-mounted toilet with a reasonable structure, which is convenient for installing and fixing the toilet when there are no embedded reinforcement parts in the hull plate; secondly, the height of the toilet can be quickly adjusted without electric drive, and the use effect is good.

When the inner skateboard moves downward to a low position, the rollers roll and contact the inner side surfaces of the pawls to push the pawls outward. There are also recessed accommodating cavities in the middle of the two side surfaces of the inner skateboard. When the inner skateboard is in a high position, the pawls can be retracted into the accommodating cavities to disengage the pawls from the ratchet bar.

[0009] Furthermore, the lifting plate structure also includes a lifting labor-saving mechanism, which includes an upper pulley, a lower pulley, a winding wheel, and a pulling belt; the upper end of the track groove is connected to a mounting cavity, and the upper pulley and the winding wheel are rotatably connected and arranged in the mounting cavity; the lower pulley is rotatably connected and arranged on the upper part of the inner slide, one end of the traction belt is fixedly connected to the inner slide, and the other end is wound on the winding wheel, and the traction belt is bent in an S shape by winding around the upper pulley and the lower pulley in turn, and the upper end of the lifting plate is provided with an opening for the traction belt to pass through.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Marine toilets usually use vacuum toilets and do not have water tanks. When the toilet body 2 is installed, the toilet is fixed to the inner decorative backboard 1 by bolts. In the prior art, fixing parts are usually prefabricated in the inner decorative backboard 1, and the bolts pass through the toilet and are screwed on the fixing parts to form a fixation. However, when fixing in this way, fixing parts must be prefabricated on the inner decorative backboard 1 in advance. If there are no fixing parts, the toilet cannot be firmly installed. Even if it is installed, the toilet is easy to loosen after being pressed down by gravity for a long time. Secondly, the installation structure using prefabricated fixing parts cannot be adjusted or shifted once installed, which is very inconvenient for people of different heights to use. The present invention provides a movable backrest reinforcement frame structure for a wall-mounted toilet, which perfectly solves the water supply problem. Example 1:

[0029] The present invention adopts an interior decorative backboard 1 and a toilet body 2 mounted on the front thereof, and adds a backrest reinforcement 3 on the back of the interior decorative backboard 1. The backrest reinforcement 3 fixes the toilet from the back of the interior decorative backboard 1, forming a supporting and fixing effect from both sides of the interior decorative backboard 1. Figure 2 、 3 As shown, the backrest reinforcement 3 is in the shape of a U, and the four side edges of the backrest reinforcement 3 are processed by galvanized steel plates, and both sides of each edge are folded to form a U-shaped folding plate 5. The material is 2mm thick galvanized steel plate, with 25mm folding edges at both ends and 50mm panel to make a U-shaped folding plate. The four U-shaped folding plates are combined and welded to form the backrest reinforcement 3. According to the position of the wall-mounted toilet body 2, the backrest reinforcement 3 is fixed to the inner decorative backboard 1 with screws; the setting of the backrest reinforcement 3 increases the force-bearing area between it and the inner decorative backboard 1, so that the bolts are fixed from the original point contact fixation to surface contact fixation, effectively improving the fixing effect, thereby making it more stable during use;

[0030] like Figure 1As shown, a lifting plate structure 4 is provided on the front of the interior decorative back panel 1, and a plurality of bolts are used to sequentially pass through the lifting plate structure 4, the interior decorative back panel 1 and the backrest reinforcement 3 for connection and fixation, forming a structure that is clamped and fixed from both sides of the interior decorative back panel 1, so that the lifting plate structure 4 can be firmly fixed on the interior decorative back panel 1, and then the toilet body 2 is installed on the lifting plate structure 4, so that the toilet body 2 can be controlled by the lifting plate structure 4 to adjust the toilet body 2 up and down.

[0031] Specifically, such as Figure 3 As shown, the lifting plate structure 4 includes a plate body 6, and two track grooves 7 are longitudinally parallel to each other on both sides of the plate body 6. Figure 4 As shown, the two track grooves 7 are slidably connected with a lifting plate 8, and ratchet bars 9 are provided on both sides of the inner walls of the track grooves 7. It should be noted that the ratchet bars 9 do not need to cover the entire side. It is only necessary to set an inwardly concave ratchet bar 9 in the middle part of the inner wall. There are still smooth inner walls on both sides of the ratchet bar 9, so as to facilitate the smooth sliding of the lifting plate 8 in the track groove 7. Ratchets 10 that cooperate with the ratchet bars 9 are provided on both sides of the lifting plate 8. When the lifting plate 8 rises, as shown in the figure, the upper end of the ratchet 10 is rotatably connected to the lifting plate 8, and a torsion spring is provided on the rotating connection part of the ratchet 10 and the lifting plate 8. The torsion spring drives the ratchet 10 to retract and move away from the ratchet bar 9 in the free state, so that the rise of the lifting plate 8 is unrestricted; in order to limit the fall of the lifting plate 8, that is, to limit the position of the toilet body 2, an inner slide plate 11 is also slidably connected inside the lifting plate 8. The inner slide plate 11 can slide longitudinally inside the lifting plate 8. When the inner slide plate 11 falls relative to the lifting plate 8, it can move the two sides The pawl 10 is pushed outward, so that the pawl 10 is stuck in the ratchet bar 9 to achieve the limit. The inner slide 11 is rotatably connected on both sides with rollers 14. When the inner slide 11 moves down inside the lifting plate 8, the rollers 14 roll in contact with the inner side of the pawl 10 to reduce the contact friction. When the inner slide 11 moves down to the low position, the rollers 14 roll in contact with the inner side of the pawl 10 to push the pawl 10 outward, so that the pawl 10 can be stuck in any tooth position of the ratchet bar 9; the inner slide 11 has two sides. A accommodating cavity 15 is also recessed in the middle of the side surface. When the inner slide 11 moves upward relative to the lifting plate 8 and is in a high position, the accommodating cavity 15 corresponds exactly to the position of the pawl 10, thereby leaving space for the rotation of the pawl 10. Under the action of the torsion spring, the pawl 10 can be rotated and accommodated in the accommodating cavity 15. When the inner slide 11 moves upward and reaches the top of the lifting plate 8, it can drag the lifting plate 8 up together. At this time, the pawl 10 is located in the accommodating cavity 15, so that the pawl 10 can release the limit state.

[0032] A mounting plate 12 is vertically fixed on the outer side of the inner slide 11. Both the lifting plate 8 and the track groove 7 are provided with a long hole 13 for the mounting plate 12 to pass through. The mounting plate 12 passes through the long hole 13 and is fixedly connected to the toilet body 2. Figure 6As shown, the mounting plate 12 on the inner slide 11 inside the two lifting plates 8 can pass through the lifting plate 8 and the track groove 7 through the long hole 13, so that the toilet body 2 is fixed on the mounting plate 12. The mounting plate 12 is provided with no less than two parallel pieces. The back of the toilet body 2 is provided with a slot that matches the mounting plate 12. The bolts pass through the toilet body 2 and are fixedly connected to the mounting plate 12. The lower part of the inner slides 11 on both sides is also connected with a synchronous pedal, which includes a connecting rod 24 and a foot pedal 25. The connecting rod 24 is U-shaped, and its two ends pass through the long hole 13 of the plate body 6 and are fixedly connected to the lower part of the two inner slides 11. The lower side of the connecting rod 24 is fixed with a foot pedal 25. When the toilet body 2 needs to be lifted, as shown in FIG. Figure 5 The figure shows the state in which the inner slide 11 moves upward when the toilet is lifted. The foot is stepped on the foot pedal 25 to fix the position of the two lifting plates 8. The toilet body 2 is lifted upward by hand. The toilet body 2 is connected to the inner slide 11 through the mounting plate 12. Lifting the toilet can actually lift the inner slide 11, so that the inner slide 11 moves upward relative to the lifting plate 8, so that the accommodating cavity 15 of the inner slide 11 is aligned with the pawl 10, that is, the pawl 10 is released, so that the pawl 10 is disengaged from the ratchet bar 9. At this time, the foot pedal 25 is released, and the portable toilet body 2 continues to move upward. At this time, the inner slide 11 drives the lifting plate 8 to move upward together. When it is adjusted to a predetermined height, as shown in FIG. Figure 4 The figure shows the internal state of the lifting plate 8 after the toilet is fixed. Use your foot to push against the foot pedal 25, and then release the toilet body 2 to move the inner slide 11 downward. The roller 14 pushes the pawl 10 out and clamps it on the ratchet bar 9 to position the toilet body 2.

[0033] On the contrary, when the toilet needs to be moved down for adjustment, the foot pedal 25 is stepped on to fix the position of the lifting plate 8, and the toilet body 2 is lifted so that the accommodating cavity 15 faces the pawl 10. The pawl 10 can shrink under the action of the torsion spring and release the limiting state, so that the toilet body 2 can be moved down to any height, and then the toilet can be fixed again in the same way as mentioned above. Example 2:

[0034] In this embodiment, the lifting plate structure 4 is further improved, and a lifting labor-saving mechanism is added to the lifting plate structure 4. In the first embodiment, the toilet is lifted and lowered by a person carrying its entire weight, so that the height adjustment can be achieved. However, the toilet usually has a certain weight. Through the improvement of the second embodiment, the height adjustment of the toilet body 2 can be achieved more conveniently. Specifically, Figure 3 、 4As shown in Figure 5, the lifting and labor-saving mechanism includes an upper pulley 16, a lower pulley 17, a reel 18, and a pulling belt 19; the upper end of the track groove 7 is connected to a mounting cavity 20, and the upper pulley 16 and the reel 18 are rotatably connected and arranged in the mounting cavity 20; the lower pulley 17 is rotatably connected and arranged on the upper part of the inner slide 11, and one end of the pulling belt 19 is fixedly connected to the inner slide 11 and the other end is wound around the reel 18, and the pulling belt 19 is sequentially passed around the upper pulley 16 and the lower pulley 17 in an S-shaped bending arrangement so that the pulling belt 19 forms a labor-saving pulley structure, and the upper end of the lifting plate 8 is provided with An opening 21 for the pulling belt 19 to pass through; the number of bending settings of the pulling belt 19 can be appropriately increased or decreased according to the width of the lifting plate 8. According to the principle of the labor-saving pulley group, the more times the pulling belt 19 is bent, the smaller the tension that needs to be applied to the end of the winding wheel 18; a winding shaft 22 is provided in the mounting cavity 20, and the winding wheel 18 is rotatably connected to the winding shaft 22. A spring 23 is also provided between the winding shaft 22 and the winding wheel 18. One end of the spring 23 is connected to the winding shaft 22 and the other end is connected to the winding wheel 18. The spring 23 provides power for the winding of the pulling belt 19.

[0035] During actual use, the tension of the clockwork spring 23 reels the traction belt 19, which assists in lifting the inner slide 11, thereby reducing the weight of the person. When the toilet body 2 is lifted, the reel 18 continuously reels the traction belt 19, thereby achieving the purpose of assisting. It should be noted that the lifting force of the toilet formed by the labor-saving pulley group formed by the spring and the traction belt 19 should be less than the gravity of the toilet body 2, so that the reel 18 will not automatically pull up the toilet. Example 3:

[0036] In order to cooperate with the lifting and lowering adjustment of the toilet, a hose section can be set on the toilet drain pipe. The inner decorative back panel 1 and the plate body 6 are both provided with a through hole 26 for the drain pipe of the toilet body 2 to pass through, and the through hole 26 is arranged longitudinally; the sewage drain pipe at the bottom of the toilet can pass through the longitudinal through hole 26. When the toilet body 2 is adjusted up and down, the through hole 26 provides space for the sewage drain pipe to move.

[0037] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
