[0002] Door locks are security devices installed on doors to control access. They have a long history, from traditional mechanical locks to today's smart locks, with continuous technological advancement. The basic function of a door lock is to ensure the door is closed through a locking mechanism, thereby protecting the safety of homes, offices, warehouses and other places.

[0003] Some door locks can be unlocked by twisting the handle when in use. After the door lock is unlocked, people need to lock it again indoors in time to prevent outsiders from accidentally touching the handle and opening the door. However, there are still cases where no one pays attention to the accidental touch, which can be exploited by people with bad intentions, resulting in the loss of indoor property. Frequent accidental touches will affect the sensitivity of various components in the door lock, resulting in maintenance costs. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] Embodiment: A door lock that prevents accidental touch, such as Figure 1-Figure 7As shown, it includes a handle 1, a lock core 2, a shaft retaining ring 3, a lock shell 4, a positioning member 5, a button 6, a spring I 7, a bottom shell 8, an insertion rod 801, a lock tongue 9, a contact rod 91, a spring II 10 and a fixing seat 11. The handle 1 is curved as a whole and can be adapted to a person's hand. A lock core 2 is rotatably arranged inside the handle 1, and a shaft retaining ring 3 is arranged on the outer side of the lock core 2. The shaft retaining ring 3 is made of elastic material and can fix the lock core 2. A lock shell 4 is arranged at the bottom of the handle 1. The lock shell 4 is a mask component, and the middle and lower part of the lock core 2 passes through the inside of the lock shell 4. The two sides of the positioning member 5 are arc-shaped, and the arc part can be used to push the component to rotate later. The positioning member 5 is sleeved on the lock core 2, and a button 6 is slidably arranged between the handle 1 and the inside of the lock core 2. The bottom end of the positioning member 5 is against the left and right sides of the lower part of the button 6, and four symmetrical through grooves are opened on the front and back sides of the lower part of the button 6. A spring Ⅰ7 is arranged at the lower part of the button 6 to drive the component to reset. A bottom shell 8 is arranged at the bottom of the lock shell 4. A certain distance is left between the bottom end of the button 6 and the upper end surface of the bottom shell 8. The interval allows the button 6 to have space to slide down when it is pressed, and the bottom end of the spring Ⅰ7 is connected to the bottom shell 8. The spring Ⅰ7 can drive the button 6 to slide upward and reset after being compressed and reset. A rod 801 is arranged on the top of the bottom shell 8. There are three insertion rods 801. The insertion rod 801 can provide space for the component to be supported. The front and rear two insertion rods 801 are inserted into two of the through grooves of the button 6, and the middle insertion rod 801 is inserted into At the bottom of the button 6, a lock tongue 9 is slidably arranged on the left side of the lock shell 4, and the left end of the lock tongue 9 extends outward. When the lock tongue 9 slides to the right and retracts into the lock shell 4, the device is unlocked. Contact rods 91 are symmetrically arranged on the front and back sides of the bottom of the lock tongue 9. The contact rods 91 on the front and back sides are in rotational contact with the arc parts on the front and back sides of the positioning member 5, and the contact rods 91 are extended into the other two through grooves at the bottom of the button 6. When the contact rods 91 are extended into the other two through grooves at the bottom of the button 6, the lock tongue 9 is in a locked state. Springs II 10 are symmetrically arranged on the inner sides of the right part of the lock tongue 9. A fixing seat 11 is fixedly arranged on the right side of the lock shell 4, and the two ends of the left part of the fixing seat 11 extend into the inner sides of the lock tongue 9. The left part of the fixing seat 11 slides with the inner sides of the right part of the lock tongue 9, and the spring II The right end of 10 is connected to the left end surface of the fixing seat 11, and the spring II10 can drive the lock tongue 9 to slide and contract or slide and extend. The front and rear sides of the lock shell 4 are symmetrically provided with assembly grooves I12, and the assembly grooves I12 are used to set the fixing parts. The front and rear sides of the bottom shell 8 are symmetrically provided with assembly grooves II121, and the positions of the assembly grooves I12 and II121 are opposite. The assembly grooves I12 and II121 are the same in size, and the fixing parts can be uniformly set. The lock shell 4 is symmetrically provided with connecting holes I13 on the left and right sides near the outside, and the bottom shell 8 is symmetrically provided with connecting holes II14 on the left and right sides near the outside, and the positions of the connecting holes I13 and II14 are opposite. The connecting holes I13 and II14 can be uniformly provided with fixing parts again.

[0026] like Figure 1-Figure 3 As shown, it also includes a screw 122, which is a hexagon socket head screw 122. The screw 122 is arranged in the cavity presented when the assembly groove I 12 is opposite to the assembly groove II 121; friction pads 15 are arranged on the front and rear sides of the handle 1. The friction pad 15 is made of rubber material and has certain friction performance, which can prevent slipping when the handle 1 is twisted; the friction pad 15 is provided with a plurality of symmetrically arranged anti-skid particles 16, and the anti-skid particles 16 can further enhance the friction performance of the friction pad 15.

[0027] When in use, first press the button 6, the button 6 will slide down from the lock core 2 into the lock shell 4 and squeeze the spring I7, so that the spring I7 is compressed and shortened by the squeezing force. At this time, the positioning piece 5 will no longer resist the button 6, and the contact rods 91 on both sides will no longer extend into the through grooves of the button 6. At this time, the lock core 2 can be rotated. At this time, hold the handle 1 and twist it clockwise. The handle 1 will rotate the lock core 2 at the same time. The positioning piece 5 will be driven by the lock core 2 to rotate, and one side of the positioning piece 5 will be in rotational contact with the contact rod 91, so that the contact rod 91 will be pushed by the positioning piece 5. When the contact rod 91 is pushed, it will drive the lock tongue 9 to slide and retract into the lock shell 4 along the left part of the positioning seat. When the lock tongue 9 slides and retracts into the lock shell 4, it will squeeze The spring Ⅱ10 is pressed, so that the spring Ⅱ10 is compressed and shortened by the squeezing force, thereby completing the unlocking operation of the door lock; and when the door lock needs to be locked again after being unlocked, the handle 1 is released. In the process of loosening the handle 1, the spring Ⅰ7 and the spring Ⅱ10 will no longer be subjected to the squeezing force. The spring Ⅱ10 generates a self-expanding force to stretch and reset to the right along the left part of the fixing seat 11 without being subjected to force, and drives the lock tongue 9 to slide outward and stretch and reset, and the spring Ⅰ7 will also generate a self-expanding force to drive the button 6 to slide upward and reset, thereby realizing the operation of automatically locking the door lock; when it is necessary to replace the internal components of the device that have been used for a long time, the components in the lock shell 4 can be inspected and repaired by removing the screws 122 from the bottom shell 8, which is convenient and quick.
