Technical Field
[0001] This utility model relates to the field of PF control box technology, specifically to an PF control box assembly structure. Background Technology
[0002] The PF control box is a low-cost, high-efficiency power control box that can reduce power harmonics and has an active power factor correction circuit. It is widely used in intelligent lighting fixtures, which have high requirements for anti-interference capabilities.
[0003] Currently, the typical structure of a PF control box involves sequentially installing three independent modules: filter, inductor, and rectifier. After installation, multiple sets of screws are used to fix the cover to the chassis, thus completing the assembly of the entire electronic controller. When the electronic components inside the control box need maintenance, the screws fixing the cover of the control box must be removed one by one to access the internal electronic components. Tightening the screws to open the box is a cumbersome operation, making the maintenance of electronic components inconvenient. Therefore, we propose a new PF control box assembly structure. Utility Model Content
[0004] The purpose of this utility model is to provide a PF control box assembly structure to solve the problem mentioned in the background art that the operation of opening the box is cumbersome, making it inconvenient to inspect and maintain the control box.

[0013] This utility model, by setting a fixing part and a clamping part on the top of the box, allows the locking knob to be loosened, and the lever to be pushed to the left. At this time, the blocking block of the lever is pushed from the horizontal structure of the sliding hole to the vertical structure. Then, the clamping part can be moved upward so that the locking knob passes through the vertical structure of the sliding hole and the clamping part can be removed. At this time, the box cover can be removed, thus enabling convenient opening of the PF control box for inspection and maintenance of internal electrical components. This eliminates the trouble of using tools to tighten bolts, making it easy to perform inspection and maintenance operations on the PF control box. The structure is simple and the operation is convenient.
[0014] When closing the PF control box, this invention allows the snap-fit groove at one end of the box cover to be inserted into the bottom of the fixing component. Then, the sliding hole of the clamping component, along with the locking knob, is inserted into the rear side of the lever. At this time, the blocking block is located inside the sliding hole, and the clamping component presses against the snap-fit groove at the other end of the box cover. After sliding the lever and the blocking block to the right and tightening the locking knob, the box cover is pressed tightly against the box body. At this time, the pressing edge of the box cover fits into the groove, and the box cover is pressed against the top of the rubber gasket. Thus, the pressing edge of the box cover and the rubber gasket improve the airtightness of the box cover on the box body, thereby improving the waterproof effect of the PF control box.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example
[0023] Please see Figures 1-5 The diagram illustrates a PF control box assembly structure, including a box body 100. Inside the box body 100 are three independent modules: a filter, an inductor, and a rectifier. The specific structure and usage of each module are existing technology. Connecting wires 101 are provided on the side walls of the box body 100, electrically connecting to electrical components inside the box body 100. Two top plates 120 and a beveled surface 200 are fixedly attached to the top of the box body 100. Mounting plates 110 are fixedly attached to both sides of the box body 100. A box cover 140 fits onto the top of the box body 100. The box cover 140 has snap-fit grooves 141 at both ends and a pressing edge 142 fixedly attached to the bottom of the box cover 140. A fixing member 130 is fitted to one end of the box cover 140, and a pressing member 150 is fitted to the other end. The fixing member 130 is fixed to the top plate 120 on the rear side of the box body 100. The clamping member 150 has a locking interface 151 on its side wall. The clamping member 150 has a lever 160 on its side wall. The lever 160 has a blocking block 163 fixedly connected to the side wall of the lever 160, which is matched with the locking interface 151. When the lever 160 slides to the left, the blocking block 163 enters the vertical structure of the sliding hole 162 and does not affect the clamping member 150 from being pulled out upward. When the lever 160 slides to the right, the blocking block 163 enters the horizontal structure of the sliding hole 162 and prevents the clamping member 150 from being pulled out upward. At the same time, tightening the locking knob 161 will cause the lever 160 to press against the side wall of the top piece 120 with the clamping member 150. At the same time, the clamping member 150 will press against the locking groove 141 at the front end of the cover 140. The lever 160 has a sliding hole 162 on its side wall, and the sliding hole 162 has a locking knob 161 on its side wall.
[0024] Specifically, the inclined nipple 200 has a groove 220 on its side wall, and a rubber gasket 221 is provided on the side wall of the groove 220. The rubber gasket 221 is made of commonly available rubber strips.
[0025] Furthermore, the box body 100 is provided with a liner 210. The liner 210 is made of commonly available bakelite and has multiple ventilation holes on its exterior. The side wall of the liner 210 is provided with a latching opening 211, which facilitates the removal of the liner 210.
[0026] Furthermore, the rubber washer 221 is fitted to the bottom of the fastener 130, and the rubber washer 221 has a rectangular structure.
[0027] Furthermore, the locking knob 161 is located on the side wall of the top plate 120, and the clamping member 150 is fitted onto the outside of the top plate 120 on the front side of the box body 100.
[0028] It is worth noting that the locking knob 161 extends through the side wall of the lever 160, and the lever 160 has a latching strip fixed to its side wall.
[0029] It is worth noting that the lid 140 fits into the bottom of the fastener 130, and a glass plate is embedded in the top of the lid 140. The glass plate is transparent, making it easy to observe the interior.
[0030] Working principle: By setting a fixing part 130 and a clamping part 150 on the top of the box body 100, when the locking knob 161 is loosened, the lever 160 can be pushed to the left. At this time, the blocking block 163 of the lever 160 is pushed from the horizontal structure of the sliding hole 162 to the vertical structure. Then, the clamping part 150 can be moved upward so that the locking knob 161 passes through the vertical structure of the sliding hole 162, and the clamping part 150 can be removed. At this time, the box cover 140 can be removed, thus enabling convenient opening of the PF control box for inspection and maintenance of internal electrical components, eliminating the trouble of using tools to tighten bolts, facilitating the inspection and maintenance of the PF control box, and making the structure simple and easy to operate; when closing the PF control box, the locking groove 14 at one end of the box cover 140 can be... After inserting the fastener 130 into the bottom, insert the sliding hole 162 of the clamping member 150 into the rear side of the lever 160 with the locking knob 161. At this time, the blocking block 163 is located inside the sliding hole 162. At the same time, the clamping member 150 presses against the snap-fit groove 141 at the other end of the cover 140. Then, slide the lever 160 with the blocking block 163 to the right and tighten the locking knob 161 to press the cover 140 onto the box body 100. At this time, the pressing edge 142 of the cover 140 is engaged with the inside of the groove 220, and the cover 140 is pressed against the top of the rubber gasket 221. Thus, the pressing edge 142 of the cover 140 and the rubber gasket 221 are used to improve the airtightness of the cover 140 on the box body 100 and improve the waterproof effect of the PF control box.
