DETAILED DESCRIPTION

[0024] The utility model will be further described in conjunction with the specific embodiment with the accompanying drawings, referring to Figures 1-3 :

[0025] Example 1

[0026] The embodiment provides a sanitary door handle, comprising:

[0027] Connecting portion 1, the beginning end articulates in door body, and the end extends forward and is parallel with door body;

[0028] Antibacterial portion 2 includes antibacterial sleeve 20 and joint 21, one end of the antibacterial sleeve 20 is detachably connected with the end of connecting portion 1, the other end is detachably connected with joint 21, and the outer surface of antibacterial sleeve 20 is coated with antibacterial coating;

[0029] Arm portion operating mechanism 3 includes elastic mounting seat 30, arm portion handle 31 and height increasing stand 32, the elastic mounting seat 30 is detachably installed at the bending portion of connecting portion 1, the arm portion handle 31 is arranged above the elastic mounting seat 30, and the height increasing stand 32 is arranged between the elastic mounting seat 30 and the arm portion handle 31.

[0030] Connecting portion 1 is used as the connecting carrier of door handle and door body, plays the role of fixing door handle and transmitting operating force, makes door handle realize opening and closing action with the hinge point as the shaft, and drives the door body to open and close. Connecting portion 1 beginning end articulates in door body, and the end extends forward and is parallel with door body, and the whole is bent, and the specific shape is similar to the extension of L type, and provides basic structure for the installation of subsequent antibacterial portion 2 and arm portion operating mechanism 3.

[0031] Antibacterial portion 2 inhibits the breeding of pathogen on the surface of door handle through antibacterial coating, reduces the risk of contact transmission, and is detachably designed to facilitate cleaning and replacement, further guaranteeing the sanitary performance.

[0032] The antibacterial sleeve 20 is the core component of the antibacterial part 2 to realize the antibacterial function. The antibacterial coating coated on the outer surface of the antibacterial sleeve 20 can effectively inhibit the breeding and spread of pathogens such as bacteria and viruses, and reduce the risk of infection of pathogenic bacteria when the user contacts the door handle. At the same time, as a part of the operating handle, it provides a surface for the user to grasp and apply force to realize the opening and closing action of the door. The antibacterial sleeve 20 is a hollow tubular structure, and the hollow inside can reduce the weight. The two ends of the antibacterial sleeve 20 can be connected with the connecting part 1 and the connector 21 through threads or other detachable methods such as buckles. Such connection methods are convenient to disassemble and assemble, and are convenient for regular cleaning or replacement of the antibacterial sleeve 20.

[0033] The connector 21 is used to close the end of the antibacterial sleeve 20 away from the connecting part 1, and plays a role in protecting the internal structure of the antibacterial sleeve 20 and enhancing the stability of the overall connection. The connector 21 is generally a block-shaped structure with a circular or square shape, and the end of the antibacterial sleeve 20 is adapted in shape to the internal structure detachably connected with the antibacterial sleeve 20. The connector 21 is detachably connected with the antibacterial sleeve 20 through the internal detachable structure.

[0034] The arm operating mechanism 3 provides a non-contact operating method for the user. The user can apply force to open and close the door by resting the forearm on the arm rest 31, reducing the opportunity for the hand to directly contact the door handle and reducing the risk of contact transmission. At the same time, the design of components such as the elastic mounting seat 30 and the heightening stand 32 ensures the stability and comfort of the operation.

[0035] The elastic mounting seat 30 mainly plays a dual role of fixation and buffering. It stably installs the arm rest 31 and the heightening stand 32 at the bending part of the connecting part 1, ensuring that the arm operating mechanism 3 will not easily shake or shift during use. At the same time, its elastic properties can provide a certain buffer when the user operates, reducing the impact of operating force on the connecting part 1 and improving the stability and comfort of the operation. The elastic mounting seat 30 is a shell structure with elasticity as a whole, and has a hollow chamber inside that is adapted to the bending part of the connecting part 1 and can tightly fit the connecting part 1. The elastic mounting seat 30 can be made of elastic rubber or silicone material and detachably connected with the connecting part 1 through buckles, bolts, etc.

[0036] The arm rest 31 is used to realize non-contact door opening or closing operation. The user applies force by resting the forearm on the rest, drives the connecting part 1 to rotate, and then realizes the opening and closing of the door body, effectively avoiding direct contact of the hand with the door handle and reducing the risk of pathogen transmission. In addition, its ergonomic design provides a comfortable operating experience for the user. The arm rest 31 can be made by adhesion or integrated with the heightening stand 32 and the elastic mounting seat 30.

[0037] The height increasing frame 32 mainly serves to increase the height and enhance the structural stability. By being arranged between the elastic mounting seat 30 and the arm rest 31, the user's forearm does not contact the antibacterial part 2. The height increasing frame 32 can be made by adhesion or integrated with the arm rest 31 and the elastic mounting seat 30.

[0038] When the user needs to open or close the door, the forearm is placed on the arm rest 31, and the arm rest 31 is pushed or pulled by the force of the forearm. Since the arm rest 31, the height increasing frame 32 and the elastic mounting seat 30 are connected, the force is transmitted to the elastic mounting seat 30 through the height increasing frame 32. The elastic mounting seat 30 transmits the force to the connecting part 1 through the detachable connection structure with the connecting part 1. The connecting part 1 rotates around the one end hinged to the door body as the axis, thereby driving the door body to realize the opening and closing action.

[0040] The embodiment provides a sanitary door handle, which comprises the technical solutions of the above-mentioned embodiments and has the following technical features.

[0041] The two ends of the antibacterial sleeve 20 are connected with the connecting part 1 and the connector 21 through a threaded mode, respectively.

[0042] The two ends of the antibacterial sleeve 20 are connected with the connecting part 1 and the connector 21 through a threaded mode, respectively, which mainly has three purposes.

[0043] Firstly, this connection mode is convenient for dismounting and mounting. When the antibacterial coating on the outer surface of the antibacterial sleeve 20 is worn or fails, or the surface of the sleeve is contaminated with a large amount of stains and is difficult to clean, the user can easily dismount it for cleaning, replacement or re-coating of the antibacterial coating, so as to ensure that the door handle always maintains good antibacterial performance and sanitary state.

[0044] Secondly, the threaded connection can provide reliable and tight fixing effect, so that the antibacterial sleeve 20 does not easily loosen or fall off between the connecting part 1 and the connector 21 when the user grips the antibacterial sleeve 20 to operate the door, so that the operating force can be stably transmitted, and the normal use of the door handle is ensured.

[0045] Thirdly, the standardized threaded connection mode is convenient for batch production and replacement of parts, reduces the production and maintenance costs, and also facilitates replacement of antibacterial sleeves 20 with different specifications, materials or antibacterial properties according to different needs in actual application, thereby improving the adaptability and flexibility of the product.

[0046] Embodiment 3:

[0047] The embodiment provides a sanitary door handle, which comprises the technical solutions of the above-mentioned embodiments and has the following technical features.
