The meaning of "several" is one or more, unless otherwise specifically limited.
[0035] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0036] See Figures 1 to 4 , a chassis lock of this embodiment includes: a first lock seat 1, a fixing seat 2, a latch module 3 and an elastic positioning component 4, wherein a snap-fitting fixed through-hole 11 is formed on one end of the first lock seat 1, the fixing seat 2 is arranged beside the first lock seat 1, and is formed with a first channel 21 opposite to the snap-fitting fixed through-hole 11, and a second channel 22 partially overlapping with the first channel 21 and partially located beside the first channel 21 and connected to the first channel 21, the latch module 3 includes a first latch 31 and a second latch 32 that are snap-fitted at a certain angle, pushing the second latch 32, the first latch 31 and the second latch 32 to move along the first channel 21 and the second channel 22 respectively, the first latch 31 passes through the snap-fitting fixed through-hole 11 and locks the first lock seat 1, and a group of elastic positioning components 4 are installed in the fixing seat 2 on both sides of the first channel 21, for elastically positioning the first latch 21, and a protrusion b1 / ball d3 respectively abutting against the first latch 31.
[0037] Specifically, the first latch 31 is formed with a limiting groove a1 and a positioning groove a2. The limiting groove a1 runs in the same direction as the second channel 22, and the positioning groove a2 is located to the side of one end of the limiting groove a1. The first latch 31 is formed with a limiting portion c on the outer side of one end of the first lock seat 1. The limiting portion c is cut from the side of one end of the first latch 31, with the cutting depth gradually decreasing to form a stepped sliding groove. During the opening and closing process, the protrusion b1 abuts against the sliding groove and moves. The setting of the limiting portion c abuts against the first lock seat 1 when locking, thereby limiting the displacement of the first latch 31. The second latch 32 vertically extends through one end of the first latch 31, and the connection between the first latch 31 and the second latch 32 is glued, effectively improving the stability of the product. Furthermore, the diameter of the second latch 32 at the end connected to the first latch 31 is smaller than that at the other end, which makes the second latch 32 more effective in opening and closing the second channel 22.
[0038] The elastic positioning component 4 includes: an abutment and positioning member 41 that passes through the fixed seat 2, and the protrusion b1 abuts against the first pin 31 to slide or be clamped into the limit groove a2, and an elastic positioning unit 42 is provided at the other end of the first pin 31, the ball b2 abuts and is limited in the limit groove a1 to slide, and interacts with the abutment and positioning member 41 according to the elastic force to press against the first pin 31. The elastic positioning unit 42 includes: a first base d1 fixed on the fixed seat 2, an elastic member d2 with one end sleeved on the fixed axis of the first base d1, one end clamped and fixed to the other end of the elastic member d2, and the other end clamped and fixed to the ball d3. Both ends of the movable pin d4 are formed with a clamping and fixing groove, and the ball d3 is clamped and fixed on one of the clamping and fixing grooves. The protrusion b1 is hemispherical, and the ball d3 is spherical.
[0039] Please combine Figures 5 to 7 , push the second latch 32 toward the first lock seat 1, and the first latch 31 is inserted into the clamping and fixing hole 11. During this process, the first latch 31 and the second latch 32 move along the first channel 21 and the second channel 22 respectively, and synchronously, the ball d3 slides along the limiting groove a1 and moves to Figure 5 As shown, the limiting portion c stops moving, the second latch 32 is turned over, and the protrusion b1 is engaged with the positioning groove a2. Figure 7 As shown, the locking function is realized; when opening, pull up and pull out the second latch 32 in the opposite direction to Figure 6 As shown, the ball d3 and the limiting groove a1 realize the limiting function, and the first lock seat 1 is opened.
[0040] From the above description, it can be seen that this product is easy to lock / loosen and simple to operate. It can quickly lock and fix the box, and the result setting is reasonable.
[0041] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
