[0025] In one embodiment, such as Figures 1 to 6As shown, a chassis 10 with a quick-release structure includes: a base 100, a chassis support frame 200, and a chassis cover 300. The chassis support frame 200 is fixed to the upper end of the base 100. One end of the base 100 is provided with multiple self-locking mechanisms 110, and the other end is provided with multiple fixing protrusions. Each self-locking mechanism 110 includes a self-locking buckle 111 and a return spring 112. The self-locking buckle 111 is rotatably fixed to the base 100, and both ends of the self-locking buckle 111 are respectively provided with a locking part 1111 and an unlocking part 1112. One end of the return spring 112 is connected to the side wall of the self-locking buckle 111, and the other end is connected to the base 100. 00 Fixed connection; the chassis cover 300 is a cover with an opening on one side. The chassis cover 300 is fitted onto the chassis support frame 200 and is detachably connected to the base 100. The inner side wall of the chassis cover 300 near the self-locking mechanism 110 is provided with a locking groove 310. The locking groove 310 matches the locking part 1111. The inner side wall of the chassis cover 300 away from the locking groove 310 is provided with a fixing hole corresponding to the fixing protrusion. The chassis cover 300 is detachably installed onto the base 100 by the locking part 1111 and the locking groove 310 engaging, and the fixing protrusion engaging with the fixing hole.
[0026] In this embodiment, the chassis support frame 200 is a cuboid frame, which is fixedly connected to the upper end face of the base 100. The chassis cover 300 is a cuboid cover with one open end, assembled from four side plates and a cover plate. The size of the chassis cover 300 matches the size of the chassis support frame 200. The chassis cover 300 is fitted onto the chassis support frame 200. A self-locking mechanism 110 is provided at one end of the base 100, and a fixing protrusion is provided at the other end. The self-locking mechanism 110 includes a self-locking buckle 111 and a return spring 112. The self-locking buckle 111 can rotate horizontally. One end of the return spring 112 is connected to the side wall of the self-locking buckle 111, and the other end is connected to the base. The self-locking buckle 111 is fixedly connected to the base 100. The self-locking buckle 111 is rotated by a certain angle by the return spring 112 and then returns to its original state. The two ends of the self-locking buckle 111 are respectively provided with a locking part 1111 and an unlocking part 1112. The side wall of the chassis cover 300 near the self-locking buckle 111 is provided with a locking groove 310 that matches the locking part 1111. The inner side wall of the chassis cover 300 away from the locking groove 310 is provided with a fixing hole corresponding to the fixing protrusion. After the chassis cover 300 is fitted onto the chassis support frame 200, the fixing hole and the fixing protrusion engage, and the locking part 1111 and the locking groove 310 on the self-locking buckle 111 engage, so that the chassis cover 300 and the base 100 are fixedly connected.
[0027] In one embodiment, there are two self-locking mechanisms 110, respectively disposed on both sides of one end of the base 100. Specifically, in order to further stabilize the chassis cover 300 and prevent it from shaking, self-locking mechanisms 110 are provided on both sides of one end of the base 100. The self-locking mechanisms 110 fix the two sides of the chassis cover 300 and cooperate with the fixing protrusion to ensure a tight connection between the chassis cover 300 and the base 100.
[0028] like Figure 5 As shown, in one embodiment, the self-locking buckle 111 has a connecting through hole in its middle, and a fixing bolt 113 is provided in the connecting through hole. The fixing bolt 113 passes through the connecting through hole and is fixedly connected to the connecting hole provided on the base 100. The self-locking buckle 111 can rotate in the horizontal direction about the fixing bolt 113 as the rotation axis. Specifically, the self-locking buckle 111 is fixed to one end of the upper surface of the base 100 by the fixing bolt 113. The self-locking buckle 111 has a connecting through hole in its middle that passes through the upper and lower surfaces of the self-locking buckle 111. The diameter of the connecting through hole is larger than the diameter of the fixing bolt 113. The size and thread of the fixing bolt 113 match the connecting hole on the base 100. The fixing bolt 113 passes through the middle through hole and connects to the connecting hole. The self-locking buckle 111 installed on the base 100 can rotate around the fixing bolt 113, thereby controlling the locking part 1111 to engage or disengage from the locking groove 310.
[0029] In one embodiment, a filter mounting groove is provided inside the base 100 along the length of the base 100, and the filter mounting groove communicates with the outer wall of the base 100 away from the self-locking mechanism 110. Specifically, the filter mounting groove is located in the middle of the base 100, one end of the filter mounting groove extends to the location of the self-locking mechanism 110, and the other end communicates with the outer wall of the base 100 away from the self-locking mechanism 110.
[0030] In one embodiment, a filter screen 140 is further included. The filter screen 140 is disposed within the filter screen mounting groove. The filter screen 140 can move closer to or away from the self-locking mechanism 110 within the filter screen mounting groove, and the length of the filter screen 140 is greater than the distance between the unlocking part 1112 and the outer wall of the base 100 away from the self-locking mechanism 110. Specifically, the filter screen 140 is inserted into the filter screen mounting groove from the end of the base 100 away from the self-locking mechanism 110. Manually pushing or pulling the filter screen 140 allows it to move closer to or away from the self-locking mechanism 110 within the filter screen mounting groove. When the filter screen 140 is assembled to the end of the filter screen mounting groove, the end of the filter screen 140 near the self-locking mechanism 110 passes over the unlocking part 1112.
[0031] like Figure 6As shown, in one embodiment, the filter screen 140 is provided with an unlocking hook 141 at one end near the self-locking mechanism. The unlocking hook 141 is used to engage the unlocking part 1112 and control the rotation of the self-locking buckle 111. Specifically, there are two unlocking hooks 141, which are respectively arranged on both sides of the end of the filter screen 140 near the self-locking mechanism, corresponding to the position of the self-locking buckle 111. When the filter screen 140 is pushed to be assembled into the end of the filter screen mounting groove, the unlocking hook 141 abuts against the unlocking part 1112, pushes the self-locking buckle 111 to rotate, and makes the locking part 1111 engage with the locking groove 310. When the filter screen 140 is pulled, the unlocking hook 141 can hook the unlocking part 1112, pull the self-locking buckle 111 to rotate, and make the locking part 1111 separate from the locking groove 310.
[0032] In one embodiment, the filter screen 140 has a push plate 143 for manually controlling the filter screen 140 at the end away from the unlocking hook 141, and the base 100 has a control notch 130 located below the push plate 143. Specifically, to facilitate the installation or removal of the filter screen 140, a push plate 143 is provided at the end of the filter screen 140 away from the unlocking hook 141, and a control notch 130 is provided at the lower end of the base 100 of the push plate 143. When it is necessary to manually remove the filter screen 140, the push plate 143 is pulled from the control notch 130 to pull the filter screen 140 out of the filter screen mounting slot, thereby improving the efficiency of the installation and removal of the filter screen 140.
[0033] In one embodiment, multiple limiting protrusions 120 are provided on the side walls of both sides of the filter installation groove, and multiple limiting grooves 142 are provided on the two side walls along the length direction of the filter 140. The shape of the limiting grooves 142 matches the limiting protrusions 120. Specifically, two limiting protrusions 120 are provided on each side wall of the filter installation groove, and the positions of the limiting protrusions 120 on both sides correspond to each other. Limiting grooves 142 corresponding to the positions of the limiting protrusions 120 are provided on each side wall along the length direction of the filter 140. The shape and size of the limiting grooves 142 match the limiting protrusions 120. When the filter 140 is assembled into the filter installation groove, the limiting grooves 142 and the limiting protrusions 120 engage to keep the filter 140 stable. At this time, the unlocking hook 141 passes over the unlocking part 1112. When it is necessary to remove the filter 140, it is only necessary to pull the push plate 143 outward from the control notch 130.
[0034] The general workflow of this utility model is as follows: First, the chassis support frame 200 is fixed on the base 100 to form the inner frame of the chassis. The inner frame and the outer cover 300 are separately assembled components. The self-locking buckle 111 and the return spring 112 are installed on the base 100. Then, the assembled outer cover 300 is fitted onto the inner frame. The filter 140 is installed in the filter mounting groove on the base 100. The self-locking buckle 111 is rotated. At this time, the fixing hole on the outer cover 300 is connected to the fixing protrusion on the base 100. The self-locking buckle 111 is not yet fully engaged. Locking the filter screen 140 further pushes it to assemble it into the bottom of the filter screen mounting slot. The filter screen 140 will push the self-locking buckle 111 to rotate 20°, locking the self-locking buckle 111. That is, the locking part 1111 on the self-locking buckle 111 engages with the locking groove 310, completing the assembly of the inner frame of the chassis and the outer cover of the chassis 300. When it is necessary to disassemble the outer cover of the chassis 300, pull the filter screen 140, and the unlocking hook 141 hooks the unlocking part 1112 to rotate the self-locking buckle 111, thereby unlocking the self-locking buckle 111 and separating the inner frame of the chassis from the outer cover of the chassis 300.
[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
