DETAILED DESCRIPTION

[0025] As used in this section and the claims, the terms "a," "an," and "the" include both singular and plural referents unless the context clearly dictates otherwise. The use of "first," "second," and the like does not imply any order, quantity, or importance, but rather is used to distinguish one element from another. Also, the use of "including," "containing," or "comprising" and the like does not exclude the presence of other elements or amounts. The use of "connected" or "coupled" to two or more elements between the coupled or connected elements does not mean that they are directly connected or coupled together.

[0026] The utility model will be explained further in detail below in combination with the drawings and specific embodiments of the specification.

[0027] Please refer to Figures 1-3 The embodiment provides a double locking mechanism applied to a cigarette packet detection device. The cigarette packet detection device comprises a box body 1 and an upper cover 2. One side of the upper cover 2 is hinged to the box body 1 through a hinge, and the other side is connected to the box body 1 through a double locking mechanism. The double locking mechanism comprises a handle 301, a handle connecting sleeve 302, a horizontal shaft 303 and a locking assembly. The horizontal shaft 303 is installed in the interior of the upper cover 2 through a connecting piece 304. The handle 301 is located outside the side plate of the upper cover 2 and is connected to the horizontal shaft 303 through the handle connecting sleeve 302. The locking assembly comprises a hook 305 and an elastic door latch 306. Two hooks 305 are arranged on the horizontal shaft 303 and are close to the two ends of the horizontal shaft 303 respectively. The corresponding positions of the box body 1 are provided with elastic door latches 306 matched with the hooks 305. The double locking mechanism further comprises an elastic limiting part and a rigid limiting part.

[0028] As shown in the figure, Figure 4 The elastic limiting part is arranged at the left end of the horizontal shaft 303 and comprises a first axial limiting plate 307 and a positioning column 308. The first axial limiting plate 307 is fixed on the connecting piece 304. The positioning column 308 is installed on the first axial limiting plate 307. One end of the positioning column 308 is provided with an elastic steel ball. Two notches are arranged on the horizontal shaft 303. When the horizontal shaft 303 rotates, the elastic steel ball at the end of the positioning column 308 is clamped into the notch, so as to realize the positioning of two angles in the opening and locking states. By adjusting the screwing depth of the positioning column 308, the limiting force is adjusted, so that the size of the force feedback to the operator is adjusted.

[0029] It should be understood that the structure of achieving positioning by snapping the elastic steel ball at the end of the positioning column into the notch is a prior art and will not be described in detail here. Preferably, an annular groove is provided on the horizontal shaft 303, with two notches located at either end of the annular groove. During the rotation of the horizontal shaft 303, the elastic steel ball always moves along the annular groove without deviation, thereby ensuring that the elastic steel ball can be smoothly snapped into the notch.

[0030] like Figure 5 As shown, a rigid stopper is located at the right end of the horizontal shaft 303 and includes a set screw 309 fixed to the horizontal shaft 303. A fan-shaped groove 310 is provided on the side panel of the upper cover 2 to cooperate with the set screw 309. When the horizontal shaft 303 rotates, the fan-shaped groove 310 limits the set screw 309, thus mechanically limiting the horizontal shaft 303 at two angles. Even if the operator continues to pull the handle beyond the elastic limit, the rigid stopper at the head of the horizontal shaft 303 (i.e., the right end of the horizontal shaft) will prevent further rotation of the horizontal shaft 303, ensuring that the handle 301 is always in an easily operable position.

[0031] To further illustrate, connector 304 is L-shaped and has two connecting surfaces. The first connecting surface is fixedly connected to upper cover 2 via bolts, and the second connecting surface defines a circular groove through which transverse axis 303 passes and can rotate. An axial stop plate 307 is fixedly connected to the second connecting surface of connector 304 via bolts. A circular through-groove is defined in axial stop plate 307, and a positioning post 308 is secured within this circular through-groove, with the top of positioning post 308 facing transverse axis 303. Preferably, positioning post 308 is a threaded positioning post, secured within the circular through-groove of axial stop plate 307 via a threaded connection.

[0032] The double locking mechanism also includes an electrical limiter. Figure 5 As shown, the electrical limit part includes a sensing piece 311, a sensing bracket and a normally open sensing switch. The sensing piece 311 is installed on the handle connecting sleeve 302, the sensing bracket 312 is installed at the corresponding position of the box 1, and the normally open sensing switch is installed on the sensing bracket 312 to realize the electrical limit of the box locking signal. After locking, an electrical signal can be generated. For boxes with airtight requirements, such as boxes with built-in radiation devices, unlocking and signaling shutdown can be achieved.

[0033] The double locking mechanism applied to the cigarette packet detection device provided by the embodiment has two locking points arranged on the device, and solves the problem of uneven locking caused by single-point locking and the warping of the upper cover. The operator can open the box body by pulling the handle, and can close the box body by pressing the handle, so that the operation is simple and convenient, and the safety of the operator is ensured. The rigid limiting part and the elastic limiting part are arranged at the head and tail of the horizontal shaft respectively. When the handle is pulled, the elastic limiting part can provide the operator with an obvious hand feeling of pulling to the position, and after the operator releases the handle, the rotation of the horizontal shaft is limited. During the opening or closing of the upper cover of the box body, the horizontal shaft does not rotate, so that the stability and safety are improved. If the operator continues to pull the handle beyond the elastic limiting part, the rigid limiting part at the head of the horizontal shaft can prevent the horizontal shaft from further rotating, so that the handle is always in an easy-to-operate position.

[0034] The above description is only preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation, direct or indirect application in other related technical fields by using the content of the utility model specification and drawings are also included in the patent protection range of the utility model.
