This just needs a kind of lockset of special requirement. At present, there is no lockset that can satisfy the opening of two keys and is certified by the Ministry of Public Security in the market.

In view of the defects of the above-mentioned existing lockset, the inventor actively researches and innovates based on his rich practical experience and professional knowledge in the design and manufacture of this type of product for many years, and cooperates with the application of academic theory, in order to create a double key with a new structure. The unlocking device can improve the general existing locks and make them more practical. Through continuous research, design, and after repeated trial samples and improvements, the utility model with practical value is finally created.

Contents of the invention

The purpose of the utility model is to provide a double-key lock unlocking device. The technical problem to be solved is to make it meet the double-key lockset that can be opened by two keys, so that it is more practical.

The purpose of this utility model and the solution to its technical problems are achieved by adopting the following technical solutions. According to the utility model, a dual-key unlocking device includes: two locks (1), a mounting plate (2), a lock paddle (3), a rotating shaft (4), a screw (5), a connecting plate (6 ); wherein the two locks (1) are respectively fixed in the mounting plate (2), and the two locks (1) are on the same horizontal line, and the connecting plate (6) is located between the two locks (1) below and installed on the mounting plate (2), and the lock (1) and the connecting plate (6) are slidably connected through the lock paddle (3), and the lock paddle (3) and the connecting plate (6) are connected through screws (5 ) connection, and the position of the screw (5) coincides with the position of the rotating shaft (4).

The purpose of the utility model and the solution to its technical problems can also be further realized by adopting the following technical measures.

Preferably, the position of the connecting plate (6) on the mounting plate (2) is not fixed.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. By means of the above technical solution, the utility model has at least the following advantages: the utility model can meet the industry's demand for public security certified double-head locks, and has a simple structure, safety and reliability, and low cost.

The above description is only an overview of the technical solution of the utility model. In order to understand the technical means of the utility model more clearly, it can be implemented according to the contents of the description, and in order to make the above-mentioned and other purposes, features and advantages of the utility model better It is obvious and easy to understand. The preferred embodiments are specifically cited below, together with the accompanying drawings, and detailed descriptions are as follows.

Detailed ways

In order to further explain the technical means and effects of the utility model to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and details of the dual-key unlocking device proposed according to the utility model will be described below in conjunction with the accompanying drawings and preferred embodiments. Its effect is described in detail below.

Fig. 1 is a schematic structural view of the dual-key unlocking device of the present invention, and Fig. 2 is a schematic view of the unlocking state of the dual-key unlocking device of the present invention.

As shown in Figure 1 and Figure 2, the utility model is a dual-key unlocking device, which includes: two locks 1, a mounting plate 2, a lock paddle 3, a rotating shaft 4, a screw 5, and a connecting plate 6; Two locks 1 are respectively fixed in the mounting plate 2, and the two locks 1 are on the same horizontal line, the connecting plate 6 is located below the two locks 1 and installed on the mounting plate 2, and the lock 1 is connected to The plate 6 is slidably connected through the locking paddle 3, and the locking paddle 3 and the connecting plate 6 are connected through a screw 5, and the position of the screw 5 coincides with the position of the rotating shaft 4. The aforementioned position of the connecting plate 6 on the mounting plate 2 is not fixed.

Wherein the two locksets 1 are the same or different. If the two locks 1 are the same, the corresponding two keys are also the same; if the two locks 1 are different, the corresponding two keys are also different.

When the dual-key unlocking device of the present invention is in the locked position and is locked, as shown in Figure 1, the centers of the two locksets 1 and the centers of the two rotating shafts 4 are connected to form a parallelogram.

When the dual-key unlocking device of the present invention is in the unlocking position, that is, unlocking, it is necessary to put the corresponding two keys into the holes of the two locksets 1 and twist them so that the two lock paddles 3 rotate simultaneously. Only the above-mentioned dual-key unlocking device can be successfully opened. As shown in FIG. 2 , the centers of the two locksets 1 and the centers of the two rotating shafts 4 are connected to form a rectangle.

The dual-key unlocking device of the utility model can be applied to some special cases, such as being applied to locks for storing guns, ammunition, safes and the like. When the emergency mechanical lock is opened, two people need to open it at the same time to open the cabinet door. The double-key lockset device of the present utility model just can satisfy this related requirement.

In summary, the utility model can meet the needs of the industry for public security certified double-headed locks, and has a simple structure, safety and reliability, and low cost.
