Description

Technical Field

[0001] This article relates to a compatible hand sanitizer holder based on an elastic locking structure. Background Technology

[0002] In the interior design of civil aircraft, hand sanitizer dispensers in lavatories are key components ensuring the hygiene needs of passengers and crew. Currently, existing aircraft hand sanitizer dispensers suffer from two main technical deficiencies, making them difficult to meet practical usage requirements:

[0003] I. Adaptability Deficiencies of Traditional Fixed-Slot Hand Sanitizer Holders: Traditional holders typically employ a "single fixed slot" structure, with slot dimensions only compatible with standard cylindrical hand sanitizer bottles of a specific capacity. When airlines change hand sanitizer types to different capacities or bottle shapes due to cost control, supplier changes, or adjustments to hygiene standards, the existing holders become incompatible with the new bottle types, necessitating complete removal and replacement with new holders. This not only increases airline procurement costs and maintenance time but also results in a large number of old holders being idle and wasted, contradicting the development concept of green aviation.

[0004] II. Operational and Reliability Defects of Existing Adjustable Holders: To address compatibility issues, some existing technologies employ screw-locking or snap-on adjustable holders. These holders require manual rotation of screws or pressing of snaps for adaptation, making the process cumbersome. Furthermore, turbulence is common during commercial aircraft flights, increasing the risk of screw stripping or snap jamming during manual operation. This can lead to the sanitary bottle failing to hold properly, such as tilting or falling off. This not only affects the user experience but may also cause slippery surfaces in the restroom, posing a safety hazard.

[0005] Given the shortcomings of the existing technologies, there is an urgent need to design an aircraft hand sanitizer holder that is highly adaptable, easy to operate, and can work stably in turbulent environments. Utility Model Content

[0006] This invention addresses the shortcomings of existing airplane hand sanitizer holders, such as poor adaptability, cumbersome operation, and low reliability under turbulent conditions, by providing an airplane hand sanitizer holder that can automatically adapt to various bottle types, operate quickly without tools, and is suitable for turbulent airplane environments.

[0007] A compatible hand sanitizer holder based on an elastic locking structure includes a housing, the housing having an internal locking mechanism.

[0008] The box body includes a support back plate, a support cover and at least two supports. The supports are all bent and have several notches. Two opposing supports abut against each other, and the corresponding notches form a groove for inserting a hand sanitizer bottle.

[0009] The locking mechanism includes a spring, a rotating shaft, a torsion spring, and a locking nut. The spring is rotatably connected to the housing through the rotating shaft. One end of the torsion spring is fixedly connected to the spring, and the other end is fixedly connected to the housing or the rotating shaft. The locking nut is sleeved on the rotating shaft to fix the rotating shaft to the housing.

[0010] When the hand sanitizer bottle is inserted into the groove, the bottle body squeezes the spring to rotate around the axis in the insertion direction. The torsion spring is compressed synchronously and generates a reverse elastic force. The reverse elastic force drives the spring to press tightly against the hand sanitizer bottle body, thereby locking the hand sanitizer bottle.

[0011] Furthermore, the bracket back plate is connected to the bracket outer cover, providing support for the box body and locking mechanism. The bracket back plate bears the core load-bearing function of the overall structure, fixing the box body in the installation position of the washbasin and transmitting the protective force of the bracket outer cover; the bracket outer cover surrounds the outside of the bracket and locking mechanism, forming a physical protective barrier.

[0012] Furthermore, the support includes a first support and a second support, each with at least two notches on its surface. The first and second supports are symmetrically arranged on the inner wall of the box body, and both are semi-circularly bent, with their centers abutting against each other. When abutting, the corresponding notches surround and form a groove for installing the hand sanitizer bottle. The symmetrical arrangement of the first and second supports forms a balanced support structure, preventing deformation of the groove due to unilateral force. The semi-circular bending design conforms to the cylindrical contour of most machine-made hand sanitizer bottles, making the inner wall of the groove fit more closely to the bottle body and reducing gaps.

[0013] Furthermore, the connection between the torsion spring and the spring sheet is located in the middle region of the spring sheet, and the connection between the torsion spring and the housing or rotating shaft is either welding or snap-fit. Connecting the torsion spring to the middle of the spring sheet ensures more even force distribution, preventing unilateral tilting or jamming due to force offset. Welding provides a permanent fixation between the torsion spring and the housing / rotating shaft, preventing loosening during vibrations, while snap-fit ​​facilitates disassembly and replacement of the torsion spring during later maintenance, reducing repair difficulty.

[0014] Furthermore, the side of the spring piece closest to the hand sanitizer bottle has an arc-shaped transition surface. When the hand sanitizer bottle is inserted into the groove, the arc-shaped transition surface can reduce the frictional resistance between the bottle body and the spring piece. The arc-shaped transition surface replaces the traditional right angle or sharp edge, which can transform the "hard collision contact" when the bottle body is inserted into a "smooth sliding contact", avoiding direct friction between the edge of the spring piece and the bottle body.

[0015] Furthermore, the locking nut is an anti-loosening nut, and an elastic washer is provided on the contact surface between the locking nut and the housing. Through a threaded self-locking structure or additional damping elements, the nut's threads are prevented from loosening during aircraft turbulence.

[0016] Furthermore, the spring is made of aluminum alloy, while the locking nut is made of alloy steel. Aluminum alloy is chosen for the spring due to its lightweight and corrosion-resistant properties. Alloy steel (such as chromium-molybdenum alloy steel or manganese-vanadium alloy steel) is chosen for the locking nut because of its high strength and wear resistance, allowing it to withstand the tightening torque when the shaft is fixed, preventing thread stripping or deformation of the nut due to stress. Additionally, alloy steel has strong fatigue resistance and can withstand the stress impact from long-term vibration.

[0017] Furthermore, both the pivot and the torsion spring are made of stainless steel. The pivot needs to rotate around the side wall of the box for a long time. Insufficient surface smoothness can cause the spring to jam. Stainless steel, after being polished, has a low surface roughness, which can reduce the frictional resistance between the spring and the pivot. At the same time, the corrosion resistance of stainless steel can prevent the pivot from rusting due to the humid environment of the bathroom, thus avoiding the rotation jamming caused by rust.

[0018] Beneficial effects:

[0019] (1) Strong adaptability and reduced cost: Through the elastic locking structure of "torsion spring + spring", the spring can automatically adjust the contact force according to the diameter of the hand sanitizer bottle. It can not only adapt to cylindrical bottles, but also to slightly curved irregular bottles; there is no need to replace the bracket due to changes in hand sanitizer specifications, which greatly reduces the airline's procurement costs and idle waste.

[0020] (ii) Easy to operate and suitable for turbulent environments: No tools are needed throughout the process. Locking and unlocking can be completed by manual operation of "push in and pull out". The steps are simple and only require one step. Moreover, the locking process is automatically completed by the spring force of the torsion spring. No manual adjustment is required. Even in turbulent aircraft environments, operation errors can be avoided and the fixation can be guaranteed to be reliable.

[0021] (III) Stable structure and long service life: The components are made of high-strength, rust-proof materials such as aluminum alloy, stainless steel and alloy steel, which can withstand the humid environment of the washroom and have strong fatigue resistance. They can withstand more than 10,000 compression-reset cycles, meeting the service life requirements of civil aircraft brackets. Attached Figure Description

[0029] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0030] Example 1: As Figure 1-4 As shown, the aircraft hand sanitizer holder consists of a box body 1 and a locking mechanism 2 located inside the box body 1. The box body 1 includes a support back plate 11, a support cover 12, and two bent supports, specifically a first support 13 and a second support 14. The first support 13 and the second support 14 are symmetrically arranged on the inner side wall of the box body 1 and are both semi-circularly bent. The center of the two bends abuts against each other. The surfaces of the first support 13 and the second support 14 are each provided with two notches. When they abut, the corresponding notches surround and form a groove for installing the hand sanitizer bottle.

[0031] The support back plate 11 is connected to the support cover 12, providing support for the box body 1 and the locking mechanism 2. The locking mechanism 2 includes a spring piece 21, a rotating shaft 23, a torsion spring 24 and a locking nut 22. The spring piece 21 is rotatably connected to the box body 1 through the rotating shaft 23. One end of the torsion spring 24 is fixedly connected to the middle area of ​​the spring piece 21, and the other end is fixedly connected to the box body 1 or the rotating shaft 23. The side of the spring piece 21 near the hand sanitizer bottle has an arc-shaped transition surface. When the hand sanitizer bottle is inserted into the groove, the arc-shaped transition surface can reduce the frictional resistance between the bottle body and the spring piece 21. The locking nut 22 is sleeved on the rotating shaft 23 to fix the rotating shaft 23 to the box body 1. The locking nut 22 is an anti-loosening nut, and an elastic washer is provided on its contact surface with the box body 1.

[0032] Usage process:

[0033] Before use, first confirm the installation status of the bracket: the bracket back plate 11 and the bracket cover 12 are firmly connected, providing reliable support for the box body 1 and the internal locking mechanism 2. The first bracket 13 and the second bracket 14 are symmetrically arranged on the inner side wall of the box body 1 and abut against each other at the semi-circular bend. The notches on their surfaces form a groove for installing the hand sanitizer bottle. At the same time, check that the spring piece 21 in the locking mechanism 2 rotates smoothly with the box body 1 through the rotating shaft 23, the torsion spring 24 is not stuck, and the anti-loosening locking nut 22 is sleeved on the rotating shaft 23 and fits against the elastic washer on the contact surface of the box body 1 to ensure the stability of the overall structure.

[0034] When in use, hold the hand sanitizer bottle and align the bottle body with the groove formed by the first bracket 13 and the second bracket 14, and slowly insert it: The bottle body first contacts the arc-shaped transition surface of the spring piece 21 near the side of the bottle body. This transition surface effectively reduces the frictional resistance between the bottle body and the spring piece 21. As the insertion depth increases, the bottle body continuously squeezes the spring piece 21, causing the spring piece 21 to rotate around the pivot 23 in the insertion direction, simultaneously driving the torsion spring 24 to compress and generate a reverse elastic force. When the hand sanitizer bottle is inserted to the preset position, the reverse elastic force of the torsion spring 24 drives the spring piece 21 to fit tightly against the outer wall of the bottle body, achieving stable locking of the hand sanitizer bottle. Even in turbulent aircraft conditions, the anti-loosening locking nut 22 and the elastic washer can prevent the pivot 23 from loosening, ensuring a continuous and reliable locking state.

[0035] When you need to remove the hand sanitizer bottle, keep the spring clip 21 away from the bottle body and pull out the hand sanitizer bottle body in the opposite direction of insertion until the bottle body is completely removed.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
