Description

Technical Field

[0001] The utility model relates to the technical field of bathroom handrails, in particular to a telescopic and adjustable stable bathroom handrail. Background Art

[0002] Bathroom handrails are horizontal bars or handles installed in toilets or bathrooms to maintain body balance or support the body. They can effectively prevent the elderly and children from falling and slipping on slippery floors. The existing bathroom handrail structure is an integrated structure and is fixedly installed on the wall. Therefore, the position of the handrail cannot be adjusted, which makes it impossible to adjust the height of the handrail and the distance from the wall, affecting the convenience of use.

[0003] After searching, the Chinese patent public number is: CN112515526A, which discloses a height-adjustable assembled bathroom handrail structure. First, two side handrail frames are fixedly installed on the wall, and then the connecting seat is fixedly installed on the side handrail frame by fasteners (such as bolts); finally, the plug-in plates at both ends of the horizontal handrail are plugged between the two connecting blocks of the connecting seat, and the joint of the plug-in plate and the connecting block is fixed by a connecting sleeve to complete the assembly. Support is provided by the side handrail frame and the horizontal handrail, especially the "C"-shaped side handrail frame, which provides support at different heights and different distances from the wall, which is convenient to use. When installing the handrail, the assembled structure allows the height of the horizontal handrail to be adjusted arbitrarily. According to the use requirements, the connecting seat is fixedly installed on the mounting holes at different heights and different distances from the wall to meet the needs of different groups of people. The shape of the connecting sleeve is conical, which realizes a smooth transition from the connecting seat to the horizontal handrail, avoiding sharp protrusions on the handrail that cause collision damage, and a number of raised anti-slip particles are provided on the surface of the horizontal handrail to increase friction.

[0004] The above patent achieves the goal of meeting the needs of different groups of people by first adjusting according to the needs of different groups of people, and then installing it on the wall through fasteners after the adjustment. However, this handrail does not have a retractable structure, which results in the handrail being able to only meet the needs of the same group of people, and not being able to adjust for different groups of people, thereby reducing the practicality of the device. Utility Model Content

[0005] The technical problems to be solved by the utility model are as follows: It solves the problem that the armrest is not provided with a retractable structure, so that the armrest can only meet the needs of the same group of people, but cannot be adjusted for different groups of people, thereby reducing the practicality of the device.

[0026] like Figure 1-6 As shown, a telescopic, adjustable and stable bathroom handrail comprises a main body 1, a slide groove 2 is provided inside the main body 1, a fixing plate 3 is fixedly installed on one side of the slide groove 2, a fixing rod 4 is slidably connected inside the slide groove 2, a limiting sleeve 5 is slidably connected to the surface of the fixing rod 4 on the side away from the slide groove 2, a supporting column 6 is fixedly connected to the bottom surface of the limiting sleeve 5, a gear 7 is fixedly installed inside the slide groove 2, a rack 8 is meshingly connected to the bottom surface of the gear 7, a plurality of first sliding blocks 9 are fixedly connected to the bottom surface of the rack 8, sliding grooves 10 are symmetrically provided on both sides of the slide groove 2, a second sliding block 11 is slidably connected inside the sliding groove 10, and the top surface of the second sliding block 11 is fixedly connected to the fixing rod 4, so that the main body 1 can be adjusted to meet the needs of different groups of people.

[0027] Extension blocks 12 are symmetrically installed on both sides of the rack 8, and a sliding rod 13 is fixedly connected to the middle of one side surface of the extension block 12, and a first spring 14 is sleeved on the side surface of the sliding rod 13 away from the extension block 12, and one side surface of the first spring 14 is fixedly connected to the extension block 12, and a blocking plate 15 is fixedly connected to the side surface of the sliding rod 13 away from the first spring 14, and a toothed plate 16 is fixedly connected to the other side of the first spring 14, and the sliding rod 13 is connected through the toothed plate 16, and the toothed plate 16 is slidably connected to the sliding groove 10, and a rotating rod 17 is fixedly connected to the middle of one side surface of the gear 7, and the rotating rod 17 is fixedly connected to a supporting block 18 away from the gear 7 and through the side surface of the body 1, and a handle 19 is fixedly connected to the side of the supporting block 18 away from the rotating rod 17, so that the fixed rod 4 can be adjusted to meet the needs of different groups of people, and the practicality of the device can also be improved.

[0028] A placing plate 20 is fixedly installed on one side surface of the body 1, and a groove 21 is symmetrically provided on one side of the rotating rod 17 close to the body 1, and a telescopic rod 22 is fixedly installed inside the groove 21. A second spring 23 is sleeved on the side surface of the telescopic rod 22 away from the groove 21, and a limiting rod 24 is fixedly connected to one side surface of the second spring 23. The other side of the second spring 23 is fixedly connected to the groove 21, and the side of the telescopic rod 22 away from the second spring 23 is fixedly connected to the limiting rod 24. A plurality of limiting grooves 25 are provided on the side surface of the body 1 close to the middle, and the limiting groove 25 is engaged with the limiting rod 24. The first slider 9 is slidably connected to the sliding groove 10. Through the cooperation between the telescopic rod 22 and the second spring 23, the limiting rod 24 is engaged with the limiting groove 25, so as to limit the rotating rod 17, so as to avoid that the fixed rod 4 is subjected to pressure and the pressure is transmitted to the gear 7, causing the gear 7 to slide, so that the device can better meet the needs of people with different needs, and at the same time, the flexibility of the device can be improved.
