[0038] The embodiment of the present application discloses a finger-pinch-proof door handle.

[0039] Reference Figure 1 , Figure 2 A finger-pinching prevention door handle includes a handle 3 arranged on a sliding door 2 and a lock seat 4 arranged on a door frame 1. There are two handles 3, both of which are frame-shaped structures and are fixedly mounted on the inner and outer sides of the sliding door 2, respectively, so that an operator can open the sliding door 2 indoors or outdoors through the handles 3. The lock seat 4 is arranged opposite to one of the handles 3, and the handle 3 is provided with a hand-holding portion 31 on the side away from the lock seat 4. There is a certain distance between the hand-holding portion 31 and the door frame 1. The operator pushes the sliding door 2 to move by holding the hand-holding portion 31, which can effectively avoid hand-pinching injuries.

[0040] Reference Figure 1 , Figure 2 The handle 3 is provided with a control mechanism 5, which is provided with a storage groove 511 and a lock tongue block 6 slidably arranged in the storage groove 511. The end of the lock tongue block 6 that can extend out of the storage groove 511 is provided with a hook structure 61, which is inserted into the lock seat 4 and can be locked with the lock seat 4. The control mechanism 5 controls the lock tongue block 6 to lock and unlock with the lock seat 4. The control mechanism 5 is provided with an elastic structure 7, which can drive the lock tongue block 6 to retract into the storage groove 511. The lock seat 4 is provided with a magnetic structure 8, which sucks the lock tongue block 6 out of the storage groove 511 and inserts it into the lock seat 4. The force of the magnetic structure 8 on the lock tongue block 6 is greater than the force of the elastic structure 7 on the lock tongue block 6.

[0041] When the sliding door 2 is closed, the sliding door 2 is pushed to slide so that the lock tongue block 6 moves toward the lock seat 4, and then the magnetic structure 8 sucks the lock tongue block 6 out of the storage groove 511 and inserts it into the lock seat 4, and then the control mechanism 5 controls the lock tongue block 6 and the lock seat 4 to lock, completing the door locking operation of the sliding door 2. When the sliding door 2 is opened, the lock tongue block 6 and the lock seat 4 are unlocked by the control mechanism 5, and then the sliding door 2 is pulled open to make the lock tongue block 6 move away from the magnetic structure 8. At this time, the elastic structure 7 drives the lock tongue block 6 to be stored in the storage groove 511, thereby preventing the lock tongue block 6 from protruding alone on one side of the handle 3, effectively preventing the lock tongue block 6 from causing damage to clothes and personal injury, and improving the safety of the sliding door 2 in use.

The seat hole 42 is arranged on the side of the lock base 4 facing the lock tongue block 6 and is connected with the seat cavity 41. The cross-sectional range of the seat hole 42 is smaller than the cross-sectional range of the seat cavity 41, so that a locking space 43 is formed at the top position of the seat cavity 41. The end position of the lock tongue block 6 protrudes upward to form a hook structure 61. The lock tongue block 6 together with the hook structure 61 can pass through the seat hole 42 and be inserted into the seat cavity 41. The magnetic structure 8 in this embodiment includes a permanent magnet 81, which can also be an electromagnet in other embodiments. The permanent magnet 81 is arranged on the cavity wall of the seat cavity 41 opposite to the seat hole 42. The permanent magnet 81 uses magnetic force to suck the end of the lock tongue block 6 into the seat cavity 41.

[0043] Reference Figure 2 , Figure 3 The control mechanism 5 in this embodiment includes a control block 51 and a support block 52. The support block 52 is fixedly connected to the side of the handle 3 close to the lock seat 4 by bolts and partially embedded in the handle 3. A sliding cavity 53 is provided in the support block 52. The sliding cavity 53 is a chamber surrounded by a cover plate 58 and a groove arranged on the side of the support block 52. The cover plate 58 and the support block 52 are detachably connected by screws. The support block 52 has strip holes 54 on both side walls that are arranged in opposite directions along the sliding direction of the sliding door 2. Both strip holes 54 are connected to the sliding cavity 53. The control block 51 is slidably arranged in the sliding cavity 53. The storage groove 511 is arranged on the side of the control block 51 close to the lock seat 4. The lock tongue block 6 passes through a strip hole 54 and slides up and down in the strip hole 54.

[0044] Reference Figure 2 , Figure 3 and Figure 4Two spring grooves 74 are provided on the side wall of the support block 52. The two spring grooves 74 are arranged on both sides of the strip hole 54 along the horizontal direction. The support block 52 is provided with an elastic component 56 in each spring groove 74. The elastic component 56 in this embodiment is a second telescopic spring 561. In other embodiments, it can also be a rubber spring or a gas spring. One end of the second telescopic spring 561 abuts against the groove wall of the spring groove 74, and the other end abuts against a positioning block 571. The positioning block 571 is a round ball and is slidably connected to the spring groove 74. A plurality of positioning blocks are provided on the side wall of the sliding cavity 53 opposite to the spring groove 74. Slot 572, the number of positioning slots 572 in this embodiment is four, each positioning block 571 corresponds to two positioning slots 572, the second telescopic spring 561 pushes the positioning block 571 to abut against the bottom wall of the positioning slot 572, for the positioning block 571, when the lock tongue block 6 and the lock seat 4 are in a locked state, the positioning block 571 is inserted into one positioning slot 572, when the lock tongue block 6 and the lock seat 4 are in an unlocked state, the positioning block 571 is inserted into another positioning slot 572, the positioning slot 572 is an arc slot, so that the positioning block 571 can slide out of the positioning slot 572 along the bottom wall of the positioning slot 572. When the control block 51 slides to the locked or unlocked position of the sliding door 2, the elastic component 56 inserts the positioning block 571 into the positioning slot 572 to position the control block 51, effectively preventing the control block 51 from moving erratically, thereby improving the stability of the sliding door 2 in the locked or unlocked state.

[0045] Reference Figure 2 , Figure 5 A guide hole 551 is provided on the lock tongue block 6 along the sliding direction of the sliding door 2. There are two guide holes 551, which are arranged in parallel up and down. A guide block 552 is fixed on the cavity wall of the storage groove 511. The guide block 552 is cylindrical. The guide block 552 corresponds to the guide hole 551 one by one. The guide block 552 is inserted into the guide hole 551 and is slidably arranged with the guide hole 551. Through the cooperation between the guide hole 551 and the guide block 552, the sliding of the lock tongue block 6 is more stable.

[0046] Reference Figure 2 , Figure 5 The elastic structure 7 in this embodiment includes a first telescopic spring 71. In other embodiments, a rubber spring, a gas spring, etc. can also be used. The lock tongue block 6 is provided with a spring hole 72 between the two guide holes 551. The spring hole 72 is arranged parallel to the guide hole 551. The cavity wall of the receiving groove 511 protrudes outward to form a spring seat 73 inserted into the spring hole 72. The spring seat 73 is slidably connected to the lock tongue block 6. The first telescopic spring 71 is fixedly arranged on the side of the spring seat 73 away from the lock seat 4. The other end of the first telescopic spring 71 is fixedly connected to the end wall of the spring hole 72 away from the lock seat 4, so that when the permanent magnet 81 adsorbs the lock tongue block 6 and moves, the first telescopic spring 71 is compressed.

[0047] Reference Figure 1 , Figure 2 and Figure 3 The handle 3 is provided with a mounting plate 91 on the side away from the support block 52. The mounting plate 91 is provided with a sliding groove 92 arranged along the vertical direction, and a sliding button 93 sliding in the sliding groove 92. The mounting plate 91 is provided with indicator marks 94 at both ends of the sliding groove 92, so that the operator can easily judge whether the sliding door 2 is in a locked or unlocked state. The sliding button 93 is provided with a baffle 95 on the side facing the support block 52. A pad 96 is provided between the baffle 95 and the support plate. The pad 96 is fixedly connected to the handle 3. The sliding button 93 drives the baffle 95 to slide on the pad 96 to reduce the wear on the support block 52. The baffle 95 is larger than the bar-shaped hole 54 for blocking, which can effectively prevent dust from entering the sliding cavity 53 and ensure the cleanliness of the sliding cavity 53. The strip hole 54 on the support block 52 extends to the pad 96, and a connecting block 97 is fixedly provided on the baffle 95. The connecting block 97 passes through the strip hole 54 and is fixedly connected to the control block 51. A clearance groove is provided on the lock tongue block 6 for the connecting block 97 to be inserted, so as to avoid collision between the lock tongue block 6 and the connecting block 97 during the storage process. The connecting block 97 slides up and down in the strip hole 54, thereby driving the control block 51 to move up and down.

[0048] The implementation principle of an anti-pinch door handle in an embodiment of the present application is as follows: when closing the sliding door 2, the operator holds the handhold 31 and pushes the sliding door 2 to close, and the lock tongue block 6 approaches the lock seat 4. When the sliding door 2 is completely closed, the force of the permanent magnet 81 on the lock tongue block 6 is greater than the force of the first telescopic spring 71 on the lock tongue block 6. The permanent magnet 81 sucks the lock tongue block 6 and the hook structure 61 into the seat cavity 41. Then the operator pushes the slide button 93 upward, and the slide button 93 drives the control block 51 to move upward through the connecting block 97. The control block 51 drives the lock tongue block 6 to move upward in the seat cavity 41, so that the hook structure 61 is inserted into the locking space 43, completing the locking of the sliding door 2. At this time, the positioning block 571 is inserted into the positioning groove 572 to ensure the stability of the position of the control block 51.

[0049] When opening the sliding door 2, the operator moves the slide button 93 downward to disengage the hook structure 61 from the locking space 43, and then pulls the sliding door 2 to open. At this time, the lock tongue block 6 moves away from the permanent magnet 81, and the first telescopic spring 71 pushes the lock tongue block 6 to be stored in the storage groove 511, thereby preventing the lock tongue block 6 from protruding alone on one side of the handle 3, effectively preventing the lock tongue block 6 from causing damage to clothes and personal injury, and improving the safety of the sliding door 2 during use.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
