Description

Technical Field

[0001] This utility model belongs to the field of door fittings technology, specifically referring to an anti-pinch door handle. Background Technology

[0002] Door handles, as a key component of doors, are widely used in various places such as residential buildings, commercial buildings, and public facilities. They are the main operating device for people to open and close doors daily. They not only provide a convenient way to operate the door, but also affect the user experience and security of the door to a certain extent, serving as an important medium connecting indoor and outdoor spaces.

[0003] Currently, although some door handles on the market are equipped with anti-pinch structures, most suffer from operational complexity in actual use. For example, some anti-pinch door handles require users to rotate or press multiple different parts to activate or deactivate the anti-pinch function; others have overly complex anti-pinch structures, requiring users to spend time finding specific operating positions and methods, making it difficult to quickly activate the anti-pinch function. These complex operating steps not only increase the difficulty of use for users but also reduce efficiency, failing to meet users' needs for convenient, efficient, and safe protection. Utility Model Content

[0004] This utility model provides a safe, reliable, and easy-to-operate anti-pinch door handle. Through the coordinated design of the sliding handle body and the self-locking limiting mechanism, it solves the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: an anti-pinch door handle, including a mounting portion disposed on the edge of the door body, and further including:

[0006] The handle body includes a handle portion and a door stop portion detachably connected to the handle portion, and the mounting portion is provided with a receiving groove for placing the handle portion;

[0007] The sliding assembly includes slide rails on both sides of the receiving groove and sliders on both sides of the handle portion. The handle portion moves horizontally along the slide rails via the sliders to switch the retracted and extended positions of the door stop portion.

[0008] The self-locking limiting mechanism includes a limiting groove at the bottom of the handle, limiting blocks on both sides of the bottom of the receiving groove, and magnetic suction components at both ends of the limiting groove opposite to the limiting blocks.

[0009] When the handle is slid to the extended position, one end of the limiting groove is locked to the corresponding limiting block by a magnetic attraction component.

[0010] The present invention is further configured such that the connecting end of the door stop is provided with a threaded portion, and the door stop is detachably connected to the handle portion through the threaded portion.

[0011] The present invention is further provided that the extended end of the door stop is provided with an elastic buffer layer.

[0012] The present invention is further configured such that the door stop is provided with a fluorescent marking layer, which is disposed on the outer surface of the elastic buffer layer.

[0013] The present invention is further configured such that the two ends of the limiting groove are provided with a first curved surface, and the limiting block is provided with a second curved surface that matches the first curved surface.

[0014] The present invention is further configured such that the magnetic suction assembly includes a first magnetic suction member disposed at both ends of the limiting groove, and a second magnetic suction member disposed on the opposite side of the limiting block.

[0015] The present invention is further provided that the outer surface of the handle portion is provided with anti-slip texture.

[0016] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0017] 1. Through the cooperation of slider, slide rail and magnetic components, the user only needs to push the handle to the extended position to automatically lock it, which simplifies the operation process and improves the ease of use of the anti-pinch function.

[0018] 2. Through the magnetic attraction components at both ends of the limiting groove and the limiting block, combined with the matching curved surface design, when the handle slides to the extended position, the curved surface guides the magnetic attraction components to accurately align and lock, forming a stable anti-pinch barrier, which enhances the stability and reliability of the anti-pinch structure and avoids accidental failure.

[0019] 3. By adding an elastic buffer layer to the extended end of the door stop, the impact force can be effectively absorbed when the door accidentally comes into contact with it, reducing collision damage; at the same time, the extended door stop forms a physical barrier, actively preventing the door from closing. Compared with the traditional anti-pinch design that only relies on buffer materials, the anti-pinch effect is greatly improved. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0026] Example 1:

[0027] This embodiment provides an anti-pinch door handle, including a mounting portion 1 disposed on the edge of the door body, and further including:

[0028] The handle body 2 includes a handle portion 20 and a door stop portion 21 detachably connected to the handle portion 20. The mounting portion 1 is provided with a receiving groove 3 for placing the handle portion 20.

[0029] The sliding assembly 4 includes a slide rail 40 disposed on both sides of the receiving groove 3 and a slider 41 disposed on both sides of the handle part 20. The handle part 20 moves horizontally along the slide rail 40 via the slider 41 to switch the retracted and extended positions of the door stop part 21.

[0030] The self-locking limiting mechanism 5 includes a limiting groove 50 at the bottom of the handle, limiting blocks 51 on both sides of the bottom of the receiving groove 3, and magnetic suction components 52 at both ends of the limiting groove 50 opposite to the limiting blocks 51.

[0031] When the handle part 20 slides to the extended position, one end of the limiting groove 50 is locked to the corresponding limiting block 51 by the magnetic attraction component 52.

[0032] Mounting part 1 is used to fix the anti-pinch door handle to the edge of the door body and is the basic component connecting the entire door handle to the door body. Mounting part 1 is usually a plate-shaped or block-shaped structure, and its shape can be adapted to the edge of the door body. Mounting part 1 is located on the edge of the door body and is generally installed at a height that is convenient for manual operation. Mounting part 1 can be connected to the door body by bolts or clips.

[0033] The handle 20 is for the user to grip and operate. Pushing the handle 20 extends and retracts the door stop 21, making it the main component for user interaction with the anti-pinch door handle. The handle 20 is typically designed in a shape that is easy to grip, such as cylindrical or curved, and is installed in the receiving groove 3 of the mounting part 1. The handle 20 and the door stop 21 can be detachably connected via snap-fit, magnetic attraction, or other means. The two sides of the handle 20 are slidably connected to the slide rail 40 of the mounting part 1 via sliders 41.

[0034] The door stop 21 extends or retracts under the action of the handle 20. When extended, it forms an anti-pinch barrier to prevent the door from accidentally closing and pinching a hand. The door stop 21 is generally rod-shaped, with one end being a connecting end for detachable connection to the handle 20, and the other end being an extending end for contacting the edge of the door frame, thereby achieving the anti-pinch function.

[0035] The sliding assembly 4 provides stable guidance and smooth sliding support for the telescopic movement of the door stop 21 or the handle 20, ensuring that the anti-pinch mechanism can operate accurately and reliably when activated or closed.

[0036] The slide rail 40 provides a sliding track for the slider 41 of the handle part 20, restricting the movement direction of the handle part 20 and ensuring that the handle part 20 moves smoothly horizontally. The slide rail 40 is generally a long strip-shaped groove or protrusion structure, arranged parallel to both sides of the receiving groove 3, and is generally integrally formed with the receiving groove 3.

[0037] The slider 41 cooperates with the slide rail 40, enabling the handle portion 20 to slide horizontally along the slide rail 40, and is a key component for realizing the movement of the handle portion 20. The shape of the slider 41 is adapted to the slide rail 40, and can be block-shaped or cylindrical, and can be embedded in the slide rail 40 to slide. The slider 41 can be installed on both sides of the handle portion 20 by welding, screw fixing, or integral molding.

[0038] The self-locking limit mechanism 5 ensures that the door stop 21 remains stably positioned when extended, preventing accidental retraction due to external force. At the same time, it can be easily unlocked when reset is required, thereby realizing the reliable activation and deactivation of the anti-pinch function.

[0039] The limiting groove 50 cooperates with the limiting stop 51 to limit the movement range of the handle part 20, and the magnetic suction assembly 52 locks the handle part 20 in the retracted and extended positions. The limiting groove 50 is an elongated groove formed on the bottom of the handle along the movement direction of the handle part 20.

[0040] The limiting block 51 cooperates with the limiting groove 50 to restrict the movement of the handle part 20, and the magnetic suction assembly 52 locks the handle part 20. The limiting block 51 is generally a block structure, and its end shape matches the end shape of the corresponding limiting groove 50 to achieve precise positioning and improve the attraction force generated by the magnetic suction assembly 52. ​​The limiting block 51 can be installed on both sides of the bottom of the receiving groove 3 by bolts or other fixing methods.

[0041] The magnetic attraction component 52 is used to lock the end of the corresponding limiting groove 50 with the limiting block 51 by magnetic attraction when the handle part 20 slides to the retracted or extended position, so as to ensure that the door stop part 21 is stably in the normal position or the anti-pinch position.

[0042] In this embodiment, when it is necessary to prevent the door from accidentally closing and pinching a hand, the user holds the handle 20 and pushes it horizontally. The sliders 41 on both sides of the handle 20 slide along the slide rails 40 on both sides of the receiving groove 3 of the mounting part 1, causing the door stop 21 connected to the handle 20 to extend out of the receiving groove 3. During the movement of the handle 20, the limiting groove 50 also moves accordingly. When the handle 20 slides to the extended position, one end of the limiting groove 50 aligns with the corresponding limiting block 51. At this time, the limiting groove 50 and the limiting block 51 at that end attract each other under the magnetic force of the magnetic attraction component 52, locking the limiting groove 50 and the limiting block 51. The door stop 21 is stably in the extended state, forming an anti-pinch barrier and preventing the door from closing. After use, the user pushes the handle 20 in the opposite direction to overcome the magnetic force of the magnetic component 52, causing the limiting groove 50 to separate from the limiting block 51. The handle 20 drives the door stop 21 to retract into the receiving groove 3, and the end of the limiting groove 50 at the other end and the adjacent limiting block 51 attract each other under the magnetic force of the magnetic component 52, so as not to affect the normal opening and closing of the door.

[0043] Example 2:

[0044] This embodiment provides an anti-pinch door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] The door stop 21 is provided with a threaded part 6 at its connecting end, and the door stop 21 is detachably connected to the handle part 20 through the threaded part 6.

[0046] In this embodiment, the door stop 21 is provided with a threaded portion 6 at its connecting end and is detachably connected to the handle portion 20, which aims to improve the product's practicality and ease of maintenance. On the one hand, when the door stop 21 or other related components wear out, age, or are accidentally damaged due to long-term use, the user can quickly unscrew the old door stop 21 for replacement without replacing the entire door handle, thus reducing maintenance costs. On the other hand, different usage scenarios have different requirements for the length, cushioning material, etc. of the door stop 21. The detachable design allows users to flexibly replace the appropriate door stop 21 according to actual needs, enhancing the product's versatility and adaptability, and enabling the anti-pinch door handle to better meet diverse usage needs.

[0047] Example 3:

[0048] This embodiment provides an anti-pinch door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0049] The extended end of the door stop 21 is provided with an elastic buffer layer 7.

[0050] In this embodiment, an elastic buffer layer 7 is provided at the protruding end of the door stop 21, aiming to improve the safety and reliability of anti-pinch protection through flexible protection. The elastic buffer layer 7 is typically designed to conform to the arc or flat shape of the protruding end of the door stop 21, and can be made of materials with high elasticity and cushioning properties such as silicone or rubber. It can be firmly fixed to the protruding end of the door stop 21 by bonding, hot pressing, or embedding. When the door accidentally closes and contacts the door stop 21, the elastic buffer layer 7 can effectively absorb the impact force, avoiding injury to the human body from hard collisions; at the same time, its flexible nature can deform during the compression process, increasing the contact area, dispersing pressure, further reducing the risk of pinching, and ensuring that the anti-pinch function plays a stable and efficient protective role in actual use.

[0051] Example 4:

[0052] This embodiment provides an anti-pinch door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] The door stop 21 is provided with a fluorescent marking layer 8, which is located on the outer surface of the elastic buffer layer 7.

[0054] In this embodiment, a fluorescent marking layer 8 is provided on the outer surface of the elastic buffer layer 7 of the door stop 21, mainly to enhance the visibility of the door handle in low-light or dark environments, thereby improving safety and convenience. The fluorescent marking layer 8 is usually a thin sheet structure, and its shape can be customized according to the outer contour of the elastic buffer layer 7, such as a wraparound strip or a conspicuous warning pattern, and can completely cover the surface of the elastic buffer layer 7. Its connection method often involves directly spraying an environmentally friendly fluorescent coating onto the outer surface of the elastic buffer layer 7, or firmly attaching a pre-formed fluorescent film through adhesive, hot pressing, or other methods, ensuring that it is not easily detached during daily use or collisions and friction, thus continuously emitting light in low light conditions to remind the user of the location of the door stop 21 and avoid safety hazards caused by accidental touch, especially suitable for nighttime or dimly lit places.

[0055] Example 5:

[0056] This embodiment provides an anti-pinch door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0057] The limiting groove 50 has a first curved surface 9 at both ends, and the limiting block 51 has a second curved surface 10 that matches the first curved surface 9.

[0058] In this embodiment, a first curved surface 9 is provided at both ends of the limiting groove 50, and a matching second curved surface 10 is provided on the limiting block 51, aiming to optimize the locking effect and operational smoothness of the magnetic attraction component 52. The curved surface design can guide the limiting groove 50 and the limiting block 51 to automatically and accurately align when the handle part 20 slides close to the extended position, reducing the probability that the magnetic attraction component 52 cannot be effectively locked due to positional deviation. At the same time, the curved surface contact can reduce the frictional resistance during the sliding process compared with the flat surface contact, making the handle part 20 push more smoothly. In the locked state, the mutual contact between the curved surfaces can form a more stable structure, dispersing the stress during magnetic locking and avoiding excessive local force, thereby improving the stability and reliability of the self-locking limiting mechanism 5 and ensuring the stable operation of the anti-pinch function.

[0059] Example 6:

[0060] This embodiment provides an anti-pinch door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] The magnetic suction assembly 52 includes a first magnetic suction member 520 disposed at both ends of the limiting groove 50, and a second magnetic suction member 521 disposed on the opposite side of the limiting block 51.

[0062] In this embodiment, the magnetic suction component 52 adopts a design in which a first magnetic suction component 520 is provided at both ends of the limiting groove 50 and a second magnetic suction component 521 is provided on the corresponding surface of the limiting block 51. The core purpose is to achieve automatic locking and reliable anti-pinch of the extended position of the handle part 20.

[0063] The first magnetic component 520 and the second magnetic component 521 are typically designed as regularly shaped blocks or sheets to ensure that their opposing surfaces fit tightly together and generate sufficient magnetic force. In terms of connection, the first magnetic component 520 is usually securely installed at both ends of the limiting groove 50 using strong adhesive, embedded slots, or screws. The second magnetic component 521 is installed on the opposing surface of the limiting block 51 using a similar process, ensuring it will not loosen or fall off during frequent use. When the handle 20 slides the door stop 21 to the extended position, the first magnetic component 520 and the second magnetic component 521 attract each other under magnetic force and automatically align and lock, providing continuous and stable anti-pinch support for the door stop 21. This prevents the door stop 21 from accidentally retracting due to external impacts or other factors, ensuring the effectiveness of the anti-pinch function. Conversely, pushing the handle 20 in the opposite direction overcomes the magnetic force to unlock the door, making operation simple and the structure reliable.

[0064] Example 7:

[0065] This embodiment provides an anti-pinch door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] The outer surface of the handle portion 20 is provided with anti-slip texture.

[0067] In this embodiment, the outer surface of the handle 20 is provided with anti-slip texture, the main purpose of which is to improve the friction and control stability when the user holds it, and optimize the user experience.

[0068] The anti-slip texture often employs an interlocking wave-like, grid-like, or striped structure, which can be molded using processes such as injection molding and mechanical engraving, and is tightly integrated with the surface of the handle 20. When the user pushes the handle 20 to extend or retract the door stop 21, these textures effectively increase the contact friction between the hand and the handle, preventing the handle from slipping out of the hand due to sweaty, wet hands or uneven force. Especially in emergency situations where the anti-pinch function is needed, it ensures that the user can accurately and stably control the movement of the handle 20, thereby quickly and reliably activating or deactivating the anti-pinch function, reducing the risk of operational errors, and further enhancing the safety and practicality of the anti-pinch door handle.

[0069] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
