[0036] In addition to the problems mentioned in the background technology, existing latches also suffer from a large number of parts, complex structure, and high production material and labor assembly costs.
[0037] The core of this application is to disclose a locking device to improve the reliability of the locking mechanism.
[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0039] like Figures 1-4 As shown in the figure, this application discloses a locking device, including a locking body 100 and a locking member 300. The locking body 100 can be connected to the outer shell 200 of the box. The locking member 300 is disposed on the locking body 100 and can move between a first position and a second position, so that the box can switch between a locked state and an unlocked state. Specifically, as shown in the figure... Figures 2-4 As shown, when the locking element 300 is in the first position, the box is in a locked state; as Figures 9-10 As shown, when the locking element 300 is in the second position, the box is in the unlocked state.
[0040] The locking device disclosed in this application has a simple structure. The locking member 300 can move between a first position and a second position, so that the box can switch between a locked state and an unlocked state. Compared with existing locking devices, the locking member 300 can reduce the risk of the box being opened accidentally and improve reliability.
[0041] Furthermore, in some specific embodiments, such as Figure 3 and Figure 5 As shown, the main body shell 200 of the box is provided with a first shaft 210, and the locking member 300 is slidably disposed on the locking body 100. When the box is in the locked state, the locking member 300 is located outside the first shaft 210, that is, the locking member 300 and the first shaft 210 are intersected, and the end of the sliding part 302 of the locking member 300 is located on the first side of the axis of the first shaft 210; when the box is in the unlocked state, the end of the sliding part 302 of the locking member 300 is located on the second side of the axis of the first shaft 210. For ease of description, as... Figure 3As shown, the area below the axis of the first shaft 210 is defined as the first side, the area above the axis of the first shaft 210 is defined as the second side, the side of the first shaft 210 facing the locking body 100 is defined as the inner side, and the side of the first shaft 210 away from the locking body, i.e., facing the outer shell 200 of the box body, is defined as the outer side. It is understood that the first and second sides, and the inner and outer sides, are relative concepts used only to distinguish different lateral orientations of the first shaft 210, and are not limitations on the actual installation position, nor should they be construed as limitations on the scope of protection of this application.
[0042] When the box is locked, the end of the sliding part 302 of the locking member 300 is located on the first side of the axis of the first shaft 210. That is, the position where the end of the sliding part 302 of the locking member 300 extends into the lower part of the axis of the first shaft 210 is the first position, so as to restrict the movement of the locking body 100 relative to the box body shell 200, that is, the locking body 100 cannot be removed from the box body shell 200. Specifically, as shown in the figure below. Figure 3 and Figure 4 As shown. When the box is in the locked state, the locking member 300 may or may not be in contact with the first shaft 210, preferably the outer surface of the sliding part 302 abuts against the outer surface of the first shaft 210.
[0043] When the box is in the unlocked state, the end of the sliding part 302 is located on the second side of the axis of the first shaft 210, that is, as Figure 3 As shown, the positions where the end of the sliding part 302 is located above the axis of the first shaft 210 are all considered the second positions. The locking body 100 can move relative to the main body shell 200 of the box, that is, the locking body 100 can be detached from the main body shell 200 of the box, thereby making the box in an unlocked state and able to be opened. The axis of the locking member 300 is intersected with the axis of the first shaft 210, preferably the axis of the locking member 300 is perpendicular to the axis of the first shaft 210. The locking member 300 cooperates with the first shaft 210, which has a simple structure and is easy to operate.
[0044] Furthermore, such as Figure 3 and Figure 6As shown, the locking body 100 is provided with a fixing member 110, and the locking member 300 slides with the fixing member 110. The fixing member 110 is provided with a limiting part 111, and the locking member 300 is provided with a locking part 310 that cooperates with the limiting part 111. When the locking member 300 is in the first position, the box is in a locked state. At this time, the limiting part 111 cooperates with the locking part 310 to limit the locking member 300. At this time, the locking member 300 is fixed relative to the fixing member 110. Specifically, one of the limiting part 111 and the engaging part 310 is a protrusion, and the other is a groove. The limiting part 111 shown in the figure is a protrusion, and the protrusion has a semi-circular structure. The figure is only an example, and the protrusion can also be other shapes. The engaging part 310 is a groove. When the locking member 300 slides along the fixing member 110, when the limiting part 111 and the engaging part 310 are engaged, the locking member 300 contacts and holds the first shaft 210.
[0045] Furthermore, in some specific embodiments, such as Figure 5 , Figure 7 and Figure 8 As shown, the locking member 300 includes a locking member body 301 and a sliding part 302. The locking body 100 is provided with a mounting hole, and the sliding part 302 is slidably engaged with the fixing member 110 through the mounting hole. The locking member body 301 abuts against and is slidably engaged with the locking body 100. Specifically, the locking body 100 is provided with a groove, and the locking member 300 is slidably disposed in the groove, with the mounting hole formed in the groove.
[0046] Specifically, such as Figure 3 , Figures 5-7 As shown, the fixing member 110 includes two fixing blocks protruding from the locking body 100, with the two fixing blocks respectively disposed on both sides of the mounting hole. The sliding part 302 includes two sliders that are slidably engaged with each fixing block. To prevent the sliding part 302 from disengaging from the fixing member 110, as... Figure 5 and Figure 7 As shown, the edge of the sliding part 302 is provided with a hook part 3021. Specifically, the hook part 3021 is provided on the edge of each slider. The fixing member 110 is provided with an anti-disengagement flange 112 that cooperates with the hook part 3021. The anti-disengagement flange 112 is the surface of each fixing block away from the locking member body 301, so as to restrict the locking member 300 from disengaging from the fixing member 110.
[0047] Furthermore, to facilitate the movement of the locking element 300 between the first and second positions, in other words, to facilitate switching the case between the locked and unlocked states, such as... Figure 5 , Figure 8 and Figure 9As shown, a pushing part 3011 is provided on the side of the locking body 301 opposite to the sliding part 302. The operator can switch the box between the locked and unlocked states by holding the pushing part 3011. It should be noted that the pushing part 3011 shown in the figure is a block structure; it is only an example. In actual use, the pushing part 3011 can also be a ring structure or other structures, as long as it is convenient to hold. Furthermore, to easily distinguish between the locked and unlocked states, locking and unlocking indicators are provided on the locking body 100.
[0048] Furthermore, such as Figures 5-7 As shown, the locking body 100 includes a first locking buckle 101 and a second locking buckle 102. The second locking buckle 102 is snapped into the first locking buckle 101 and also snapped into the first shaft 210. A fixing member 110 is disposed on the first locking buckle 101. Specifically, as shown... Figure 6 As shown, the first latch 101 is provided with a first elastic latching part 1011, the second latch 102 is provided with a latching part 1022 that cooperates with the first elastic latching part 1011, and the second latch 102 is provided with a second elastic latching part 1021 that cooperates with the first shaft 210. The first latch 101, the second latch 102, and the locking member 300 are preferably made of plastic. The latching device disclosed in this application embodiment includes only three parts: the first latch 101, the second latch 102, and the locking member 300. It has a simple structure, is easy to manufacture, and is easy to assemble. Compared with existing latching devices, it can reduce production material costs and labor costs.
[0049] Furthermore, to improve the strength of the connection, in some specific implementations, such as Figure 5 As shown, in some specific embodiments, the main body shell 200 of the box is provided with a second shaft 220, and the first latch 101 is provided with a third elastic latch 1012. The third elastic latch 1012 can engage with the second shaft 220. The first shaft 210 and the second shaft 220 are respectively provided on the first shell and the second shell of the box.
[0050] The locking device disclosed in this application is suitable for boxes of various types and sizes. Specific application examples include... Figure 11 and Figure 12As shown. In actual use, the application principle is as follows: When the box needs to be locked, firstly, the locking body 100 is engaged with the first shaft 210. Then, the locking member 300 is pushed downwards, moving to the first position. The sliding part of the locking member 300 is arranged perpendicularly to the first shaft 210 and extends below the first shaft 210 to restrict the movement of the locking body 100 relative to the box body shell 200, thus preventing the locking body 100 from detaching from the box body shell 200. When unlocking is required, the locking member 300 is pushed upwards, moving to the second position. The locking member 300 disengages from the first shaft 210, allowing the locking body 100 to move relative to the box body shell 200. By operating the locking body 100, the locking body 100 is disengaged from the first shaft 210, thus unlocking the box.
[0051] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
