Description

Foolproof lock

The invention relates to a blocking device, in particular to a foolproof lock that can prevent the lock piece from sliding when the drawer is opened so that the lock piece does not accidentally prevent the drawer from closing.

The use of drawer-type storage cabinets to store items is a common means of storage at home. Some of these storage cabinets are further equipped with locks on the drawers for added security; however, when the drawers are closed, if the locks are accidentally turned due to the drawer movement, In the locked state, or the user accidentally rotates the lock before the drawer is closed, the lock mechanism of the lock may collide with the locker body when the drawer is closed, which may cause damage to the user.

In view of this, the author has accumulated years of research in related fields and practical experience to create a foolproof lock to improve the lack of the above-mentioned conventional techniques.

The main purpose of this creation is to provide a foolproof lock, which can prevent the lock piece or the lock rod installed on the lock of the drawer from moving arbitrarily when the drawer is opened.

In order to achieve the above purpose, the foolproof lock of this creation includes a chute, which has a mounting opening and two groove walls located on both sides of the mounting opening, one end of the chute has a moving opening, and the other end of the chute has a fixing. Each groove wall has an L-shaped groove extending from the installation opening to the bottom of the chute and turning to a direction perpendicular to the moving opening; a movable piece is fitted into the chute, and the movable piece faces corresponding to each groove wall respectively There is a guide block, each guide block corresponds to each L-shaped groove, and the movable member is inserted into the chute by the mounting port, so that the movable member can reciprocate in a direction perpendicular to the moving port. Extending, the opening direction of the groove is toward the fixed member, the movable member has a blocking portion on one side of the corresponding mounting opening, and the blocking portion projects out of the chute; and an elastic element is installed in the groove of the movable member and Lean on the fixture.

In order to clearly and fully disclose this creation, the illustrations of the preferred implementations are listed, and the implementation manners are described in detail below.

Please refer to the first to third drawings to reveal the drawings of the embodiment of the creation. The above-mentioned drawings illustrate the foolproof lock A of the creation, which includes a chute 1, which has a mounting opening 15 and is respectively located at the mounting opening. Two groove walls 10 on both sides of 15, one end of the chute 1 has a moving port 11, the other end of the chute 1 has a fixing member 12, and each of the groove walls 10 has an L-shaped groove 13 from the installation port 15 to the chute 1. The bottom portion extends and turns to the direction perpendicular to the moving port 11. Each L-shaped groove 13 is symmetrical to each other and is open at one end of the corresponding mounting port 15 and closed at the other end. The chute 1 may further have a mounting member 14, The chute 1 can be installed at the position of the lock head 5 of a drawer 40, and the mounting member 14 is a piece of tenon in this embodiment, and is used to be snapped into a preset groove;

A movable member 2 is fitted in the chute 1. A guide block 20 is provided on the surface of the movable member 2 corresponding to each groove wall 10, and each guide block 20 corresponds to each L-shaped groove 13. The movable member 2 is inserted into the slide by the installation port 15. Slot 1, each guide block 20 can be moved in each L-shaped groove, so that the movable member 2 has a degree of freedom of reciprocating movement in a direction perpendicular to the moving port 11, and the movable member 2 has a groove 22 along the perpendicular to the moving port 11. The direction of the opening of the groove 22 is toward the fixed member 12. The movable member 2 has a blocking portion 21 on one side corresponding to the mounting port 15. The blocking portion 21 protrudes beyond the chute 1. The blocking portion 21 can be moved by the movable member 2. The surface extends outside the chute 1 at a predetermined angle to match the position of the lock lever 50 that needs to be blocked. In this embodiment, the lock lever 50 is located at a higher position, so the blocking portion 21 extends at an upward angle; An elastic element 3 is installed in the groove 22 of the movable member 2 and leans against the fixed member 12.

When assembling, first put the elastic element 3 into the groove 22 and compress the elastic element 3. The movable member 2 can be inserted into the chute 1 by the side of the installation opening 15 of the chute 1, and each guide block 20 of the movable member 2 is inserted by each L when inserted. The open end of the groove 13 slides in, and each guide block 20 slides to the end in the direction of the vertical movement port 11 of each L-shaped groove 13. At this time, the elastic element 3 is released to let the movable member push the movable part by its own elastic force. 2. The elastic element 3 and leaning on the fixing member 12 can complete the assembled state as shown in the first figure. The movable member 2 can reciprocate in a direction perpendicular to the moving port 11 with force. Then, the foolproof lock A is mounted on the drawer 40 of the storage cabinet 4 by using the mounting member 14 and located around the lock 5.

In the fourth figure, when the drawer 40 is closed, the movable member 2 is compressed, and the blocking portion 21 is away from the lock lever 50 of the lock head 5. The size of the blocking portion 21 is designed so that the lock lever 50 can freely lock the heel at this time. The user can freely open or lock the drawer 40 by rotating between the opened states.

In the fifth figure, when the drawer 40 is opened, the elastic element 3 pushes the movable member 2 with its own elastic force, the blocking portion 21 moves to the movement path of the lock lever 50 of the lock head 5 at the same time, and the blocking portion 21 blocks the movement of the lock lever 50 To the locked state; at this time, neither the vibration when the drawer 40 is opened nor the carelessness of the user cannot move the lock lever 50 to the locked state. Therefore, when the drawer 40 is closed, the probability that the lock lever 50 is accidentally in the locked state and hits the storage cabinet 4 to cause damage is minimized.

However, the above is only a preferred embodiment of this creation. When it cannot be used to limit the scope of this creation, all changes and modifications obvious to those skilled in the industry should be deemed not to be inconsistent. The essence of this creation.
