Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety door locks, in particular to an anti-slip door handle. Background Art
[0002] Door handles are indispensable door accessories that are both decorative and functional. Door handles are classified into ceramic, solid wood, metal, glass, crystal, plastic, alloy and other materials.
[0003] There are many kinds of existing door handles, which are installed in pairs on the inside and outside of the door. The door handle handles usually adopt two forms: "7" shape and round. However, these two kinds of door handles only differ in shape. In the process of opening the door, they need to be rotated manually to release the lock pin to open the door.
[0004] However, when these two types of door handles are rotated, the wrist is required to drive the door handle to rotate. When the wrist is deflected, the angle of the "7"-shaped handle will form an angle with the horizontal plane. Therefore, it is easy for the hand to slide down along the "7"-shaped handle, causing the handle and the hand to slip off. When the round-headed handle is in use, the force point is closer to the rotation axis. Therefore, the force required to rotate the round-headed handle is greater than that of the "7"-shaped handle. Therefore, when the hands are wet, both handles are more likely to slip, and then the handles are likely to rebound quickly and cause damage to the lock core. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an anti-slip door handle so as to solve the technical problems mentioned in the above background technology.
[0006] The above technical objectives of the utility model are achieved through the following technical solutions:
[0007] A non-slip door handle comprises a door panel, a hinge is installed on one side of the door panel, a sliding groove is provided on the inner side of the door panel, installation grooves are provided on both sides of the door panel, a mounting shaft is provided at one end of the mounting groove, a handle is fixedly connected to the outer surface of the mounting shaft, transmission gears are provided at both ends of the mounting shaft, a lock core is provided inside the sliding groove, a return spring is provided at one end of the lock core, and a rebound protection mechanism is provided at one end of the lock core and below the return spring.
[0008] Furthermore, the corners of the handle are arranged in an arc shape, and the arc surfaces are all embedded with transverse anti-slip strips.
[0009] Furthermore, the lock core includes a slider, which is located inside the sliding groove. Two transmission racks are provided on both sides of the slider, and the transmission racks are meshed with the transmission gear. A lock pin that passes through the sliding groove is provided at one end of the slider.
[0010] Furthermore, one end of the return spring is fixedly connected to the inner wall of the sliding groove, and a telescopic rod is provided at the connection between the return spring and the sliding block.
[0011] Furthermore, the rebound protection mechanism includes a slot, the slot is opened at one end of the sliding block, and a connecting rod is slidably connected inside the slot.
[0012] Furthermore, a sealing ring is provided at one end of the connecting rod inserted into the slot.
[0013] In summary, the utility model includes at least one of the following beneficial technical effects:
[0014] 1. This anti-slip door handle, when in use, pulls the handle to deflect the mounting shaft, and then drives the lock core to move through the transmission gear to achieve the purpose of unlocking. Compared with the prior art, in the process of holding and pulling the handle, the wrist does not participate in rotation or force, and only the arm force is needed to pull the hand to deflect the handle. In the process of pulling the handle, the straight line direction of the handle will not form an angle with the horizontal plane, thereby reducing the possibility of the hand slipping along the straight line direction of the handle, and effectively avoiding the problem of the handle slipping and loosening;
[0015] 2. This anti-slip door handle, during the process of the slider rebounding, the slider is pushed back by the elastic force of the return spring and the pressure of the gas, and the friction between the sealing ring and the slot reduces the speed of the slider. When the return spring gradually stretches to a normal state, the slider stretches the telescopic rod under the effect of inertia, and in the process of the slider stretching the telescopic rod, a negative pressure is formed inside the slot. At this time, the negative pressure inside the slot quickly absorbs the slider to the end of the connecting rod to prevent the slider from colliding with the side wall of the sliding slot, thereby achieving the effect of protecting the lock core.

DETAILED DESCRIPTION
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0022] Example:
[0023] Reference Figure 1-Figure 3 The utility model discloses an anti-slip door handle, comprising a door panel 1, a hinge is installed on one side of the door panel 1, a sliding groove 2 is arranged on the inner side of the door panel 1, mounting grooves 3 are opened on both sides of the door panel 1, a mounting shaft 4 is arranged at one end of the mounting groove 3, a handle 5 is fixedly connected to the outer surface of the mounting shaft 4, transmission gears 6 are arranged at both ends of the mounting shaft 4, a lock core 7 is arranged inside the sliding groove 2, a return spring 8 is arranged at one end of the lock core 7, and a rebound protection mechanism 9 is arranged at one end of the lock core 7 and below the return spring 8.
[0024] In the present embodiment, when in use, the handle 5 is pulled to deflect the mounting shaft 4, and then the lock core 7 is driven to move through the transmission gear 6 to achieve the purpose of unlocking, and the return spring 8 is set to push the lock core 7 back after the handle 5 is released, so that the handle 5 is embedded in the mounting groove 3 again. Compared with the prior art, in the process of holding the handle 5 and pulling the handle 5, the wrist does not participate in the rotation, and only the arm force is required to pull the hand to deflect the handle 5. In the process of pulling the handle 5, the straight line direction of the handle 5 will not form an angle with the horizontal plane, thereby reducing the possibility of the hand slipping along the straight line direction of the handle, effectively avoiding the problem of the handle 5 slipping and loosening, and through the setting of the rebound protection mechanism 9, the movement of the lock core 7 is damped during the rebound of the lock core 7, thereby reducing the movement speed of the lock core 7 and protecting the lock core 7.
[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the corners of the handle 5 are arranged in an arc shape, and transverse anti-slip strips are embedded in the arc surfaces.
[0026] In this embodiment, the handle 5 with arc-shaped corners is used to improve the comfort of holding the handle 5, and the transverse anti-slip strip is provided to increase the friction with the hand during pulling the handle 5, thereby further achieving an anti-slip effect.
[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the lock core 7 includes a slider 71, and the slider 71 is located inside the sliding groove 2. Two transmission racks 72 are arranged on both sides of the slider 71, and the transmission racks 72 are meshed with the transmission gear 6. A lock pin 73 that passes through the sliding groove 2 is arranged at one end of the slider 71.
[0028] In this embodiment, the slider 71 is used to install the transmission rack 72, and the transmission rack 72 is meshed with the transmission gear 6. When the handle 5 is pulled to rotate the installation shaft 4, the transmission gear 6 can be driven to slide through the transmission gear 6, causing the slider 71 to slide, thereby achieving the effect of receiving the locking pin 73 into the sliding groove 2 and compressing the return spring 8.
[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, one end of the return spring 8 is fixedly connected to the inner wall of the sliding groove 2 , and a telescopic rod 81 is provided at the connection between the return spring 8 and the slider 71 .
[0030] In this embodiment, when the locking pin 73 is received into the sliding groove 2, the sliding block 71 compresses the return spring 8, so that the return spring 8 accumulates potential energy. After the handle 5 is released, the return spring 8 rebounds to bounce the sliding block 71 back and extend the locking pin 73 out of the sliding groove 2. When the length of the telescopic rod 81 is the shortest and the return spring 8 is in a state without force, there is a gap between the end of the sliding block 71 away from the return spring 8 and the groove wall of the sliding groove 2. When the length of the telescopic rod 81 is the longest and the return spring 8 is not under force, the end of the sliding block 71 away from the return spring 8 contacts the groove wall of the sliding groove 2.
[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the rebound protection mechanism 9 includes a slot 91 , the slot 91 is opened at one end of the slider 71 , and a connecting rod 92 is slidably connected inside the slot 91 .
[0032] In this embodiment, the movement trajectory of the slider 71 is guided by the arrangement of the slot 91 and the connecting rod 92, so as to protect the movement of the slider 71 and prevent it from shaking.
[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a sealing ring 93 is provided at one end of the connecting rod 92 inserted into the slot 91 .
[0034] When the locking pin 73 is retracted toward the inside of the sliding groove 2, the slider 71 will first compress the telescopic rod 81 and then compress the return spring 8. In this process, the gas inside the slot 91 will be compressed. During the rebound of the slider 71, the slider 71 is pushed back by the elastic force of the return spring 8 and the pressure of the gas, and the movement speed of the slider 71 is reduced by the friction between the sealing ring 93 and the slot 91. When the return spring 8 gradually stretches to a normal state, that is, when the return spring 8 is not under force, the slider 71 will stretch the telescopic rod 81 under the effect of inertia. Since the slider 71 is still moving at this time, and one end of the connecting rod 92 is fixedly connected to the groove wall of the sliding groove 2, a negative pressure will be formed inside the slot 91 during the sliding and stretching of the telescopic rod 81. At this time, the negative pressure inside the slot 91 will quickly adsorb the slider 71 to the end of the connecting rod 92 to prevent the slider 71 from colliding with the side wall of the sliding groove 2, thereby protecting the lock cylinder 7.
[0035] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
