Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of safety door lock, in particular to a button hidden type handle. BACKGROUND

[0002] As an important barrier for home safety protection, the security door is very important for protecting personal and property safety. When purchasing a home door, in addition to the appearance style, the consumers generally value the quality and security performance of the home door lock.

[0003] At present, the security doors sold on the market generally include a door frame, a door leaf, a door handle, an observation hole, a lock body, a lock core and a lock hole which are reasonably combined. These security doors have low safety because the lock hole is usually completely exposed outside the door body, and the lock core is indirectly exposed outside the door body.

[0004] Therefore, the Chinese patent CN107130891A discloses a security home door with hidden lock hole. A hidden clamping position is arranged on the door body, and a lock hole is arranged on the hidden clamping position. A pushing hole is further arranged on the hidden clamping position, and a pushing block is installed in the pushing hole. A pressing hole is arranged on the door body, and a pressable elastic silica gel film is arranged at the pressing hole. The color or pattern of the elastic silica gel film is adapted to the door body. A pressing block is installed in the pressing hole, and a lever is arranged inside the door body. One end of the lever is connected to the pressing block, and the other end of the lever is connected to the pushing block. A hidden block with a size adapted to the hidden clamping position is arranged on the door body, and the color or pattern of the hidden block is adapted to the door body. When in use, the elastic silica gel film can be pressed by a finger. The elastic silica gel film is concave inward under stress, and the pressing block in the pressing hole is pressed. The pressing block drives the pushing block at the other end of the lever to be convex outward through the lever. The pushing block is pushed out through the pushing hole, and the hidden block is pushed out. At this time, the hidden block is taken out as a whole, and the lock hole in the hidden clamping position is exposed. Then, a key is used to open the door.

[0005] The security home door with hidden lock hole described above adopts a lever transmission mode. The lever arm must have appropriate structural strength to meet the force transmission requirement. The rotation plane of the lever is perpendicular to the cover surface after the installation of the hidden cover, and the lever arm extends along the surface of the door leaf. Therefore, a relatively large space is required in the door body to meet the requirement of the rotation of the lever. Therefore, the door body must be combined with the door leaf. The pressable elastic silica gel film in the pressing hole for driving the hidden block must be arranged on the outer surface of the door leaf in a naked state. After a period of use, the pressed elastic silica gel film will have pressed marks, which can be easily found to cause economic loss. On the other hand, the hidden block and the hidden clamping position arranged on the door body are detachably embeddedly connected, and are easy to be lost in use. SUMMARY

[0006] Therefore, the technical problem to be solved by the present application is that the existing hidden lock hole anti-theft home door, although hiding the lock hole behind the hidden block, can improve the anti-theft performance to a certain extent, but the elastic silica gel film in the pressing hole driving the hidden block is in a naked state, which is easy to be found to cause economic losses.

The first elastic member 91 is arranged in the spring groove provided at the bottom of the buckle 5 and between the bottom wall of the buckle installation groove 23, and under the clamping biasing force of the first elastic member 91, the buckle 5 can always protrude out of the buckle installation groove 23.Figure 6 As shown in Figure 4 As shown in

[0069] Further, one side of the clamping head 51 towards the lock core cover 3 is formed with a first clamping inclined surface, and correspondingly, the groove edge of the clamping groove 32 on the lock core cover 3 is formed with a second clamping inclined surface which first contacts the clamping head 51 of the clamping buckle 5; pressing the lock core cover 3 makes the first clamping inclined surface and the second clamping inclined surface interact to push the clamping buckle 5 to move from the clamping position to the disengaging position against the clamping biasing force, so that the clamping head 51 is clamped into the clamping groove 32 beyond the groove edge of the clamping groove 32.

[0070] In the embodiment, as shown in Figure 1 , Figure 5 and Figure 6 , Figure 1 The right end of the button 6 is used to abut against the left end of the clamping buckle 5, and the button 6 is used to push the clamping buckle 5 to make the clamping buckle 5 separate from the lock core cover 3 by pressing the button 6 to make the button 6 move right.

[0071] The clamping buckle 5 and the button 6 are two separate components, the button 6 is movably arranged on the handle main body 1, and the button 6 and the clamping buckle 5 are connected through a separation transmission mechanism.

[0072] Specifically, as shown in Figure 5 The separation transmission mechanism includes a first separation inclined surface arranged on the button 6 near one end of the clamping buckle 5, and a second separation inclined surface arranged on the clamping buckle 5 near one end of the button 6.

[0073] The above structure, the lower end of the button 6 (i.e. the right end of the button 6 in Figure 1 The lower end of the clamping buckle 5 (i.e. the left end of the clamping buckle 5 in Figure 1The left end of the clasp 5 is provided with a second separation slope, and the second separation slope is arranged towards the lock core cover 3, that is, the first separation slope is on the upper side of the second separation slope. It can be understood that when the button 6 is pressed to the right side, the first separation slope slides to the right side on the second separation slope. Since the height of the second separation slope gradually increases from left to right, under the horizontal direction limiting effect of the clasp mounting groove 23, the clasp 5 moves downward along the clasp mounting groove 23 under the extrusion effect of the first separation slope of the button 6, until the clamping head 51 is separated from the lower clamping groove 32 of the lock core cover 3.

[0074] In the embodiment, the clasp fixing piece 8 is connected with the handle cover 2, the clasp 5 is provided with a sliding step 52, the clasp fixing piece 8 is fixed at the clasp mounting groove 23, and the clasp fixing piece 8 cooperates with the clasp mounting groove 23 to form a sliding groove suitable for the sliding of the sliding step 52, so that the clasp 5 can move up and down along the sliding groove.

Of course, the two clasp fixing pieces 8 can also be arranged as an integral structure.

[0076] In the embodiment, as shown in Figure 1 , the second elastic member 92 is arranged between the button 6 and the clasp fixing piece 8. After the button 6 is pressed, the button 6 pushes the clasp 5 to the right side against the reset biasing force of the second elastic member 92, and after the button 6 loses external force, the button 6 can be reset under the reset biasing force of the second elastic member 92. The second elastic member 92 can be a coil spring.

[0077] In the embodiment, as shown in Figure 1 , the button hidden handle further comprises a top cover pin 7 and a third elastic member 93. The right end of the top cover pin 7 penetrates the top cover pin hole 24 of the handle cover 2 and abuts against the lock core cover 3. The left end of the top cover pin 7 is provided with an anti-extraction step. The third elastic member 93 is arranged between the anti-extraction step and the handle main body 1. After the lock core cover 3 is separated from the clasp 5, the top cover pin 7 moves to the right under the abutting biasing force of the third elastic member 93, so as to push the lock core cover 3 out of the lock core cover groove 25. The diameter of the anti-extraction step is greater than that of the top cover pin hole 24, so as to prevent the top cover pin 7 from being separated from the top cover pin hole 24.

[0078] In the embodiment, the handle main body 1 is formed with a top cover pin groove 13, and the third elastic member 93 is a coil spring arranged in the top cover pin groove 13.

[0079] The button-concealed handle provided in this embodiment has a lock cylinder cover 3 with a covered position and an open position. In the covered position, the lock cylinder cover 3 is located in the lock cylinder cover groove 25 and is engaged with the snap-fit ​​5; in the open position, the lock cylinder cover 3 is separated from the snap-fit ​​5, and the lock cylinder cover 3 is configured to rotate relative to the anti-disengagement pin 4 to move away from the lock cylinder cover groove 25 under the action of external force.

[0081] First, press button 6 to overcome the reset bias force of the second elastic element 92. Figure 1 Move to the right side, thereby pushing the buckle 5 down in the buckle mounting groove 23 until the buckle 5 separates from the lock cylinder cover 3. The lock cylinder cover 3 protrudes out of the lock cylinder cover groove 25 under the push of the top cover pin 7. Then manually rotate the lock cylinder cover 3 away from the lock cylinder cover groove 25 to reach the open position.

[0082] In order to facilitate the lock cylinder cover 3 being away from the lock cylinder cover groove 25, the edge of the lock cylinder cover 3 and Figure 1 The protruding parts of the lock cylinder cover 3's slot 32 are all chamfered 33 to facilitate the lock cylinder cover 3's removal from the lock cylinder cover slot 25; additionally, an arc-shaped edge 34 is provided on the upper part to facilitate smooth and unobstructed 360° rotation. Preferably, the arc-shaped edge 34 is concentrically arranged with the rotation shaft 31.

[0083] This embodiment provides a button-concealed handle. By setting the button 6, which controls the opening of the lock cylinder cover 3, to be located on the back of the handle body 1, it is not easy to find. Since the second lock cylinder hole 21 is located inside the lock cylinder cover groove 25, and the lock cylinder cover 3 is placed on the lock cylinder cover groove 25, the concealed button 6 can improve the overall security of the lock body. Moreover, the button 6 is more convenient to use when it is located at the back of the handle body 1, which is ergonomic and more convenient. Specifically, when in use, pressing the button 6 will pop out the lock cylinder cover 3, and the arc-shaped edge 34 with the same center can rotate smoothly and unobstructed in any direction from 360°. Pressing the lock cylinder cover 3 again will automatically close and lock it.
