Description

  This utility model concerns a kind of building security facility. Specifically, it relates to a kind of low-noise building entrance security device.

  In accordance with the development of modernization, some high-rise buildings sometimes have a lot of activity, especially office buildings and condominiums. In order to consider the safety factor, it is necessary to install a security device at the entrance, reducing the phenomenon of theft prevention. However, the structure of the conventional entrance security device is complicated and the installation cost is high.

  The technical problem solved by the utility model is to provide a low noise building entrance security device with a simple structure and stable operation.

  This utility model is realized by the following technical scheme. A kind of low-noise building entrance security device includes a locking mechanism mounted inside a wall and a security door mounted under the wall. The locking mechanism includes a lateral chute installed in the wall and a drive motor installed in the leftmost wall of the lateral chute. A drive shaft was fixedly mounted on the output shaft of the drive motor. The right end of the drive shaft was attached to the right end of the wall through a bearing. A slide set was mounted on the drive shaft. A lock block capable of sliding up and down was installed in the slide set. A limit protrusion is installed at the bottom of the slide set that is used to limit the lock block. A return spring was installed between the lock block and the limit protrusion. A wheel is attached to the upper end of the lock block, and a slide rail is installed in the wall at the upper end of the lateral chute. From left to right, the slide rail has a press-fitting plane portion and a transition plane portion and a flat portion extending. At the upper end of the security door, a lock hole is installed for blending with the lock block. Silent cotton was attached between the drive motor and the wall. Silent cotton can greatly reduce the noise generated when working the drive motor.

  Furthermore, in the technical scheme, the upper end of the lock block slides with the inner wall of the slide set at a wide side. The lower end is a narrow side that can accommodate the expansion and contraction of the return spring.

  Since the beneficial effect of this utility model uses the rotation of the drive motor, the slide set is moved left and right on the drive shaft. The lock block can be expanded and contracted during the movement process of the slide set. When extending, the security door is locked. The security door is unlocked when retracted. The structure of this utility model is simple and easy to install. The cost of installation is greatly reduced and the operation of this utility model is stable.

It is a sketch of a new type of low-noise building entrance security device. It is a sketch when the security device at the entrance of a new kind of low noise building locks.

  The present invention will be described in detail with reference to FIGS. This kind of low-noise building entrance security device includes a lock mechanism mounted inside the wall 3 and a security door 1 mounted below the wall 3. The locking mechanism includes a lateral chute 14 installed in the wall 3 and a drive motor 2 installed in the wall 3 at the left end of the lateral chute 14. A drive shaft 15 is fixedly mounted on the output shaft of the drive motor 2. The right end of the drive shaft 15 was attached to the right end of the wall 3 through a bearing. A slide set 9 was attached on the drive shaft 15. A lock block 8 capable of sliding up and down was installed in the slide set 9. A limit protrusion 12 used to limit the lock block 8 is installed at the bottom of the slide set 9. A return spring 11 was attached between the limit protrusion 12 and the lock block 8. A wheel 7 is attached to the upper end of the lock block 8, and a slide rail is installed in the wall 3 at the upper end of the lateral chute 14. The slide rail has, from left to right, a press-fitting plane part 4 and a transition plane part 5 and a flat part 6 extending. A lock hole 13 for blending with the lock block 8 is installed at the upper end of the security door 1. A silencer cot 21 was attached between the drive motor 2 and the wall 3. The noise-reducing cotton can greatly reduce the noise generated when the drive motor 2 is operated.

  The upper end of the lock block 8 is wide and slides with the inner wall of the slide set 9. The lower end is a narrow side and can accommodate the expansion and contraction of the return spring 11.

  When used, the slide set moves to the left using the rotation of the drive motor. In the process, the lock block is slowly pressed. Finally, the lower end of the lock block is inserted into the lock hole. After stopping the operation of the drive motor, the binding is performed by utilizing the fact that the drive shaft and the screw in the slide set are aligned. After taking advantage of the reverse rotation of the drive motor, the slide set is moved to the right. In this process, the lock block can be slowly retracted from the role of the return spring. Eventually, the lock block is fully retracted into the slide set. At this time, the lock is released and the security door is opened.

  Since the beneficial effect of this utility model uses the rotation of the drive motor, the slide set is moved left and right on the drive shaft. The lock block can be expanded and contracted during the movement process of the slide set. When extending, the security door is locked. The security door is unlocked when retracted. The structure of this utility model is simple and easy to install. The cost of installation is greatly reduced and the operation of this utility model is stable.

  According to the above, this is only a specific implementation method of the utility model. However, the protection scope of the utility model is not limited to this, but the protection scope of the utility model is to change with a change that has not undergone any creative labor. Therefore, the scope of protection of this utility model is based on the scope of protection limited to the claim for rights.
