Description

Technical Field

[0001] The utility model relates to the technical field of wooden door unlocking, in particular to a wooden door unlocking device. Background Art

[0002] Wooden doors, that is, wooden doors, can be divided into many categories according to materials, craftsmanship and uses. They are widely used in civil, commercial buildings and residences. Lock opening, which means opening the lock, has become an industry and there are professional locksmith qualification certificates.

[0003] The prior art publication number is CN 203266843 U, which is a wooden door keyhole positioning device. This patented technology can be equipped with longitudinal and transverse positioning blocks for drilling machines and trimming machines respectively, so as to accurately determine the size and position of the keyhole. Moreover, one setting can be applied to both drilling machines and trimming machines at the same time, thus ensuring the consistency of the keyhole and saving effort and time.

[0004] At present, traditional wooden door unlocking methods are that carpenters measure the dimensions and mark the lines on site according to the size of the lock body, and then chisel it manually, which is time-consuming and laborious, and the dimensional accuracy is not enough, and the aesthetics are even worse. Therefore, a homemade unlocking machine is needed, but the existing unlocking device requires the operator to manually mark and unlock during use, which greatly reduces the efficiency of unlocking. On the contrary, the size positioning is set in advance, and the hand-cranked wheel allows the tool to move back and forth, left and right, and it will naturally stop when it reaches the required size. In addition, the wooden door is fixed on the clamp, and the unlocking speed has a qualitative leap. Ordinary manual unlocking takes 20 minutes to unlock a door. After adopting the unlocking device, it can guarantee one door per minute, which greatly improves the unlocking efficiency. Therefore, improvements are proposed to the wooden door unlocking device.

[0005] In order to solve the above problems, we have made improvements and proposed a wooden door unlocking device. Utility Model Content
