Description

Technical Field

[0001] This utility model relates to the field of panel locks, and in particular to a panel structure for a panel lock. Background Technology

[0002] Chinese Patent Publication No. CN209277699U, published on August 20, 2019, discloses a panel structure for a panel lock. The panel includes a housing and an inner liner. The housing is stamped from a color-coated steel sheet and has rivet plates on its sides. The inner liner is injection molded from resin and has recessed holes into which bolts or nuts are embedded. Alternatively, an insert injection molding process can be used to embed the bolts or nuts into the injection mold, and the inner liner will be enclosed during injection molding. The inner liner has a skirt around its perimeter, and through holes corresponding to the rivet plates on the sides of the housing. The housing and inner liner are riveted together, with the sides of the housing engaging with the skirt of the inner liner. The rivet plates pass through the corresponding through holes and are then riveted in place. The structure has the following technical problems: 1. The left and right edges of the color steel plate are flanged, and the flanges are equipped with rivet plates that need to be bent after passing through the through holes of the shell to achieve riveting and fixing. Therefore, the rivet plates are long and consume a lot of materials; 2. After the rivet plates pass through the through holes of the shell, secondary processing is required to achieve riveting. The process is complicated, and the metal panel may spring back or break after riveting, resulting in failure to fix and increasing the scrap rate; 3. The color steel plate is only fixed by the rivet plates on the edges. The middle of the color steel plate is not pressed tightly onto the plastic shell. The middle of the color steel plate is prone to arching and unevenness, resulting in a thin visual effect. Utility Model Content

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1, see Figures 1 to 9 As shown, a panel structure for a panel lock includes a panel body, which includes a base plate 2 and a decorative panel 1. The decorative panel 1 is disposed on the front side of the base plate 2. The decorative panel 1 has a flange 13, which is bent toward the side of the base plate 2. The side of the base plate 2 has a boss 20, and the boss 20 has an embedding groove 22 corresponding to the edge of the flange 13. The edge of the flange 13 has a buckle 15, and the embedding groove 22 has a fastening position 24. The buckle 15 and the fastening position 24 are fastened together.

[0037] The edge of the flange 13 is provided with a pin 14, and the buckle 15 is provided on the pin 14; the embedding groove 22 is provided with a slot 23 corresponding to the pin 14, the slot 23 passes through the front and back of the boss 20, and the buckle 24 is provided in the slot 23.

[0038] The decorative panel 1 is a sheet metal part; the base plate 2 is an injection molded part, and the surface of the base plate 2 is provided with several hollow parts 27.

[0039] The buckle 15 is C-shaped and is located on the edge of the pin 14. The outer side of the C-shaped groove is chamfered. The buckle 24 is connected between the left and right sides of the slot 23. The cross-section of the buckle 24 is adapted to the inner shape of the C-shaped groove.

[0040] When the buckle 15 is fastened to the buckle position 24, the buckle position 24 deforms after contacting the C-shaped groove of the buckle 15, thereby squeezing into the groove cavity, and then restoring its deformation to achieve fastening.

[0041] The decorative panel 1 has flanges 13 on both the left and right sides, and the base plate 2 has protruding edges 21 on the front corresponding to the upper and lower ends of the decorative panel 1. The protruding height of the protruding edges 21 is greater than or equal to the thickness of the decorative panel 1, so as to avoid the edges of the upper and lower ends of the decorative panel 1 being exposed, thereby enhancing the aesthetics and preventing scratches.

[0042] The panel body is also provided with a handle 3, which is connected to the panel body through a reset rotation assembly 4. The reset rotation assembly 4 includes a rotor 41, a reset spring 42, a washer 43, and a retaining ring 44. One end of the rotor 41 is separately connected to the handle 3, and the other end of the rotor 41 passes through the decorative panel 1 and the base plate 2 in sequence and is connected to the reset spring 42, the washer 43, and the retaining ring 44 in sequence. The reset spring 42 is connected between the rotor 41 and the base plate 2. The washer 43 is connected to the rotor 41 in a transmission manner. The retaining ring 44 is engaged with the outer periphery of the rotor 41. The reset spring 42 and the washer 43 are closely disposed between the base plate 2 and the retaining ring 44. The outer end of the rotor 41 is provided with a stepped surface 414, which is close to the surface of the decorative panel 1.

[0043] Specifically: the decorative panel 1 and the base plate 2 are provided with shaft holes 11 corresponding to the rotor 41, and the rotor 41 is rotatably engaged with the shaft holes 11; the back of the base plate 2 is provided with a cavity 211 corresponding to the return spring 42, the washer 43 and the retaining ring 44, and a limiting block 212 is provided in the cavity 211. The stepped surface 414 of the rotor 41 is close to the outer edge of the shaft hole 11, and the other end of the rotor 41 is provided with a transmission hole 411 (square hole). A set of opposite sidewalls of the transmission hole 411 are provided with slots 412. The return spring 42 is a coil spring, and the center and outer periphery of the coil spring are respectively provided with a first contact and a second contact. The first contact is inserted into the slot 412 of the rotor 41, and the second contact abuts against the sidewall of the limiting block 212. The gasket 43 has a central hole, and a positioning foot 431 is provided on the opposite side of the central hole. The positioning foot 431 cooperates with the slot 412 of the rotor 41 to achieve transmission cooperation. The outer periphery of the gasket 43 also has a limiting groove 432, which is sleeved on the limiting block 212. The transmission hole 411 of the rotor 41 is inserted into the square shaft 8.

[0044] The panel body is also provided with a lock cylinder 5. The front end of the lock cylinder 5 is provided with a limiting rib 51. The decorative panel 1 and the base plate 2 are both provided with lock cylinder holes 12. The rear end of the lock cylinder 5 passes through the lock cylinder holes 12 in sequence. The back of the base plate 2 is provided with a tensioning member. The tensioning member is connected to the rear end of the lock cylinder 5 and makes the limiting rib 51 of the lock cylinder 5 press against the decorative panel 1.

[0045] The tensioning component includes a screw 61 and a clip 6. The clip 6 is U-shaped and has a through hole at its bottom. The clip 6 passes over the lock cylinder 5, and the two ends of the opening of the clip 6 abut against the back of the base plate 2. The rear end of the lock cylinder 5 has a screw hole 52, and the screw 61 passes through the through hole and connects to the screw hole 52.

[0046] The back of the base plate 2 has abutment portions 25 on both sides corresponding to the lock cylinder hole 12. The two ends of the opening of the code piece 6 are bent outward (with arc-shaped bends 62), forming a trumpet shape. When the screw 61 is tightened, the bottom of the code piece 6 moves towards the lock cylinder 5. The arc-shaped bends 62 at both ends of the opening of the code piece 6 guide the left and right arms of the code piece 6 to slide outward and open, thereby generating a rebound force. This causes the screw 61 and the screw hole 52 to form a self-locking constraint, preventing the screw 61 from loosening and the lock cylinder 5 from disengaging, thus playing an anti-theft role.

[0047] Example 2 differs from Example 1 in that: See [link to example 1] Figure 10 As shown, the buckle 15 is in the shape of a barb and is disposed on the side of the pin 14. The latch 24 is connected to the slot 23 on the side opposite to the buckle 15. Specifically, a U-shaped groove is punched on the surface of the pin 14, and the sheet metal inside the U-shaped groove protrudes to form the barb-shaped buckle 15. The latch 24 is a barb shape opposite to that of the buckle 15.

[0048] Combination Figure 10 As shown, when the pin 14 of the decorative panel 1 is inserted into the slot 23 in the direction of arrow D, the buckle 15 touches the latch 24, and the buckle 15 retracts in the direction of arrow E to avoid the latch 24; when the pin 14 is fully inserted into the slot 23, the buckle 15 slides to the bottom of the latch 24, and the buckle 15 springs back in the direction of arrow F, blocking the latch 24 from the front and back, thus completing the latching.

[0049] Combination Figures 12 to 15 As shown, the panel body is provided in two sets, namely the front panel body G and the rear panel body H. The back of the bottom plate 2 of the front panel body G is provided with a connecting stud 26, and the connecting stud 26 is provided with a threaded sleeve 71. The rear panel body H is provided with a bolt 72, which passes through the decorative panel and the bottom plate 2 of the rear panel body H in sequence and is connected to the threaded sleeve 71.
