[0019] This utility model is as follows Figures 1 to 3 As shown:
[0020] A connection structure between a front panel and a lower component includes a vertically arranged front panel body 1 and a vertically arranged lower component body 2 at its lower end. Two positioning blocks 5 are fixedly connected to the upper end of the lower component body 2 to cooperate with positioning grooves to prevent the lower component body 2 from shifting away from the front panel body 1. The two positioning blocks 5 are located on both sides of a connecting block 3. The lower end of the front panel body 1 is provided with a positioning groove corresponding to the positioning blocks 5. The upper end of the positioning blocks 5 slides into the positioning groove. A connecting block 3 is fixedly connected to the upper end of the lower component body 2 to realize the assembly and combination between the front panel body 1 and the lower component body 2. The lower end of the front panel body 1 is provided with a connecting groove corresponding to the connecting block 3. The upper end of the connecting block 3 slides into the connecting groove. A reinforcing rod 4 is fixedly inserted into the lower component body 2 to improve the firmness between the connecting block 3 and the lower component body 2. The lower end of the reinforcing rod 4 is fixedly inserted into the lower component body 2, and both ends of the reinforcing rod 4 are T-shaped structures.
[0021] In this embodiment, a bolt rod 6 is inserted into the outer side wall of the front bulkhead body 1 to form a bolt with a bolt head 7. The bolt rod 6 and the front bulkhead body 1 are connected by a thread. The outer side wall of the connecting block 3 is provided with a wedge-shaped groove corresponding to the bolt rod 6 to accommodate the bolt rod 6 and lock the position of the connecting block 3. One end of the bolt rod 6 passes through the front bulkhead body 1 and extends into the wedge-shaped groove. The other end of the bolt rod 6 is fixedly connected to a bolt head 7 to facilitate the user to rotate the bolt rod 6. An anti-loosening washer 8 is sleeved on the bolt rod 6 to prevent loosening.
[0022] In this embodiment, a slot is provided on the outer side wall of the front panel body 1, and a horizontally arranged locking rod 9 is slidably inserted on the inner side wall of the slot to cooperate with the locking hole to lock the rotation capability of the bolt head 7. The bolt head 7 has a plurality of locking holes corresponding to the locking rod 9 arranged in a ring on the side facing the bolt rod 6. One end of the locking rod 9 passes through the slot and slides into the locking hole. The other end of the locking rod 9 is slidably inserted with a first guide rod 10 to guide the movement of the locking rod 9. The end of the first guide rod 10 away from the locking rod 9 is fixedly connected to the inner side wall of the slot. A spring 11 is slidably sleeved on the first guide rod 10 to provide elastic support for the locking rod 9. The two ends of the spring 11 are fixedly connected to the locking rod 9 and the inner side wall of the slot, respectively.
[0023] In this embodiment, a slider 13 is fixedly connected to the upper end of the lever 9 to drive the lever 9 to move. A groove is provided on the side of the front panel body 1 facing the slot. The groove is located above the slot. A hollow groove is provided at the bottom of the groove. The upper end of the slider 13 slides through the hollow groove and extends into the groove. A rubber block 14 is fixedly connected to the outer wall of the slider 13 to improve the comfort when manually pushing the slider 13. The end of the rubber block 14 away from the slider 13 passes through the groove. A second guide rod 12 is slidably inserted in the slider 13 to guide the slider 13. The two ends of the second guide rod 12 pass through the slider 13 and are fixedly connected to the inner wall of the groove.
[0024] The working principle of this utility model:
[0025] First, insert the connecting block 3 into the connecting groove to easily assemble the lower component body 2 and the front panel body 1. At the same time, the positioning block 5 will automatically insert into the positioning groove to ensure that there is no misalignment between the two. Then, manually push the slider 13 to move along the groove direction. The slider 13 drives the locking rod 9 to move into the slot, so that the locking rod 9 is released from the locking hole, thereby unlocking the rotation function of the bolt head 7. At this time, rotating the bolt head 7 will drive the bolt rod 6 to screw into the wedge groove under the action of the thread, locking the position of the connecting block 3 and completing the assembly of the lower component body 2 and the front panel body 1. Finally, release the slider 13. The elastic force of the spring 10 pushes the locking rod 9 back into the locking hole, relocking the rotation of the bolt head 7, effectively preventing loosening and improving the reliability of the overall structure.
