Example 1

Fig. 1 shows an exploded schematic view of a key box assembly according to the present embodiment, fig. 2 shows an assembled schematic view of a key, a first sliding member and a second sliding member according to the present embodiment, and referring to fig. 1 and 2 in combination, a key box assembly includes a key box body 1 and a key box cover 2, and a key 3, a first sliding member 4, a second sliding member 5 and a spring 6 connecting the key box body 1 and the key 3 are installed in the key box body 1.

Specifically, the key box 1 is provided with a base 11, a rear wall 12 and a side wall 13, the other side of the key box 1 opposite to the rear wall 12 is provided with a mounting opening 14, and the key 3 is mounted at the mounting opening 14. One end of the key 3 protrudes out of the key box body 1, and the other end is arranged in the key box body 1. The part of button 3 protrusion in button box body 1 is pressing part 31, installs the part in button box body 1 for connecting portion 32, and connecting portion 32's width is greater than pressing part 31's width to the connecting portion 32 of button 3 can block in the inboard of installing port 14, prevents that button 3 from droing in the button box body 1. One end of the spring 6 is installed in the middle of the connection portion 32, and the other end is connected to the rear wall 12 of the key case 1.

The connecting portion 32 is provided with first guide portions 33 on both sides of the spring 6, while the first slider 4 is provided with first slide portions 41 adapted to the first guide portions 33, and the first slide portions 41 are connected to the first guide portions 33. In the present embodiment, the first guide portion 33 is a first chute 331 provided at both sides of the connecting portion 32. The first sliding groove 331 is formed inside the connection portion 32 and is inclined toward the inside of the base 11 by one end near the pressing portion 31 and the key cap 2. The first sliding portion 41 is a first sliding block 44 protruding from both sides of the first sliding member 4, and the first sliding block 44 is a block structure adapted to the first sliding groove 331 and having an inclination angle. The first slider 44 engages with the first slide groove 331 and moves the first slider 4 along the first slide groove 331.

Specifically, the first slider 4 includes a first slider body 42, a first limiting rib 43 and a first slider 44 that are integrally formed, the first limiting rib 43 is disposed on a side of the first slider body 42 near the base 11 and protrudes toward the rear wall 12, and the first slider 44 is disposed on a side of the first limiting rib 43 near the side wall 13. The first slider body 42 is recessed from the base 11 toward the keycap 2 to form an opening 45, and the first limiting rib 43 and the first slider 44 are separately disposed on two sides of the opening 45 to form the first slider 4 with a symmetrical structure.

When the key box assembly is assembled, the upper end of the first slider body 42 protrudes from the first hole site 21 provided on the key box cover 2. The spring 6 is connected to the rear wall 12 of the key case 1 through an opening 45 at the lower end of the first slider 4. One end of the first stopper rib 43 is closely attached to the rear wall 12, and the other end is held between the connecting portions 32 by the first slider 44.

Wherein the opening 45 provides a limited space for the spring 6, so that the spring 6 does not deform or change relative position with the movement of the first slider 4. The first limiting rib 43 can be abutted against the inner side of the keycap 2 to prevent the first sliding piece 4 from falling off from the first hole site 21, and meanwhile, the first sliding piece 4 is limited between the rear wall 12 and the key 3.

On the other hand, the bottom of the connecting part 32 of the key 3 is provided with a second guiding part 34, and the second guiding parts 34 are symmetrically arranged at two sides of the spring 6. The second slider 5 is provided with a second slider portion 51 adapted to the second guide portion 34. In this embodiment, the second guiding portion 34 is provided with a second slider 341 protruding toward the base 11, the second slider 341 is inclined from the inner side of the key 3 toward the side wall 13, and a symmetrical structure having a V-shape is formed at the lower end of the key 3. The second guide portion 34 on each side of the connection portion 32 is provided with two second sliders 341, and a groove is formed between the two second sliders 341. Accordingly, the second sliding portion 51 of the second slider 5 is provided with a second sliding groove 52 recessed toward the base, the direction in which the second sliding groove 52 is inclined coincides with the direction in which the second sliding block 341 is inclined, and the second sliding block 341 near the outer side of the key 3 is engaged with the second sliding groove 52, so that the second guiding portion and the second sliding portion are engaged with each other, and the second slider 5 can be moved in the direction in which the second sliding block 341 is inclined.

Of course, in some embodiments, the second guiding portion 34 may be provided with a groove, and the second sliding portion 51 may be provided with a protruding slider, so that the second guiding portion 34 and the second sliding portion 51 may be engaged with each other and may slide relatively.

In addition, the base 11 is also provided with a guide bar 111 extending in the direction of the side wall 13, and the second slider 5 is provided with a third slider 53 engaged with the guide bar 111 on the side close to the base 11, and the third slider 53 is a groove recessed toward the second slider 51. The second sliding piece 5 is limited by the guide strip 111 and the second guide part 34, and protrudes from the side wall 13 of the key box body 1 to form a second hole 131.

In this embodiment, the use of the key box assembly is described by taking the case that the key box assembly is mounted in the power box and fixed with the guide rail as an example. Fig. 3 and 4 show an initial state diagram and a pressed state diagram of the key box assembly of the present embodiment mounted in a power box and fixed with a guide rail, respectively, and referring to fig. 1 to 4, the key box assembly of the present embodiment is mounted in a power box 7, and in the initial state, the power box 7 is engaged with the guide rail 8 through a second sliding member 5 of the key box assembly, and the first sliding member 4 protrudes from the key box cover 2 and is parallel to an upper end of a protruding power box rib 71 on the power box 7.

The pressing portion 31 is applied with force to move the key 3 toward the inside of the key case 1 against the elastic force of the spring 6. At this time, the first slider 4 is restrained between the rear wall 12 and the key 3, and therefore cannot move in the direction in which the key 3 moves. However, as the key 3 moves toward the rear wall 12, the first slider 44 of the first slider 4 moves toward the key box cover 2 along the first chute 331 in the vertical direction, so that the first slider 4 protrudes from the key box cover 2 and abuts against the guide rail 8. At this time, the upper end of the first slider body 42 protrudes from the power box rib 71, and the power box 7 overcomes the magnetic force between the power box and the guide rail 8, and a distance is generated between the power box and the guide rail 8. Similarly, the second sliding member 5 cannot move along the direction in which the key 3 moves due to the limitation of the guide bar 111, but the second sliding portion 51 of the second sliding member 5 moves along the second guiding portion 34, so that the second sliding member 5 finally retracts into the key box 1 along the direction of the guide bar 111.

To sum up, when the pressing portion 31 is pressed, the first sliding member 4 protrudes toward the key box 1, so that the power box 7 overcomes the magnetic force of the guide rail 8 and is far away from the guide rail 8, and the second sliding member 5 contracts inward toward the key box 1, and releases the engagement state with the guide rail 8. Therefore, when the user dismantles the power box 7 provided with the key box assembly of the embodiment, the user only needs to press the key 3 to dismount the power box 7 from the guide rail 8, and overcomes the magnetic force of the guide rail 8 when releasing the buckling state with the guide rail 8, so that the dismounting efficiency of the user can be greatly improved, and the dismounting process is easier and more convenient.

It should be noted that, in some embodiments, the key case body 1 and the key case cover 2 of the key case assembly may be integrally formed with the case body of the power supply case 7. In addition, the key box assembly is not limited to being mounted in the power box 7, and in actual use, the key box assembly may be mounted in a rail lamp body or other devices.

Example 2

The present embodiment provides a key box assembly, which has substantially the same structure as that of embodiment 1, and includes a key box body 1 and a key box cover 2, wherein a first sliding member 4 and a second sliding member 5 movably connected to a key 3 are installed in the key box body 1, the first sliding member 4 is connected to a rear wall 12 and a connecting portion 32 of the key 3 and protrudes from the key box cover 2, and the second sliding member 5 is connected to a base 11 and the connecting portion 32 of the key 3 and protrudes from a side wall 13 of the key box body 1.

Fig. 5 shows a top view of the key box of the present embodiment, which is different from embodiment 1 in that the rear wall 12 of the key box 1 of the present embodiment protrudes with a guiding rib 121, and the guiding rib 121 is attached to the first slider 4. The guide rib 121 is cylindrical in shape as a whole, and is aimed at reducing friction between the first slider 4 and the rear wall 12 when it moves in the vertical direction. Further, the guide rib 121 preferably has a smooth, scratch-free surface so that the coefficient of friction is minimized. In the practical application process, substances such as lubricating oil and the like can be dripped into the guide rib 121, so that the first sliding piece 4 and the guide rib 121 can slide relatively smoothly.

Example 3

Fig. 6 is a schematic diagram showing the assembly of the key, the first slider and the second slider according to the present embodiment, and referring to fig. 1 and 6, the structure of a key box assembly according to the present embodiment is similar to that of embodiment 1, except for the structure of the key 3.

In the present embodiment, the first guide portions 33 of the key 3 are guide surfaces 332 provided on both sides of the connecting portion 32. The guide surface 332 is inclined from the side of the upper end of the connecting portion 32 near the pressing portion 31 toward the inside of the base 11. Specifically, the connecting portion 32 is provided with guide blocks 333 on both sides of the spring 6, and the guide blocks 333 are inclined surfaces on the side facing the rear wall 12. In the present embodiment, two guide blocks 333 are disposed on two sides of the connecting portion 32, and the guide blocks 333 are parallel to each other. The guide surface 332 is formed by inclined surfaces of the guide blocks 333 on each side toward the rear wall 12 side. Accordingly, the first sliding portion 41 is a sliding surface 412 provided on the first slider 4, and the sliding surface 412 is bonded to the guide surface 332. In this embodiment, the sliding surface 412 is disposed on a side of the first sliding member 4 near the key 3, and includes a first sliding block 44 and a side surface of the first limiting rib 43 near the key 3. The first limiting rib 43 and the first slider 44 protrude from both sides of the first slider body 42, so that the contact area between the sliding surface 412 and the guiding surface 332 is increased. Similarly, the two sides of the connecting portion 32 increase the area of the guide surface 332 by providing two guide blocks 333, so that the structure between the first slider 44 and the key 3 is more stable. Of course, in some embodiments, a guide block 333 having a large inclined surface may be provided on each side of the connection portion 32, and may be attached to the sliding surface via the inclined surface. Also, the structure of the first slider 4 can be modified accordingly on the basis of the foregoing.

When the key box assembly of the present embodiment is assembled, one end of the first limiting rib 43 of the first sliding member 4 abuts against the rear wall 12, and the other end abuts against the guiding surface 332 of the key 3. Pressing the key 3 moves the key 3 in the direction of the rear wall 12. At this time, the first slider 4 moves upward along the guide surface 332 along with the movement of the key 3, and finally, the first slider body 42 protrudes from the key box cover 2 and abuts against the outer guide rail 8, so that the power box 7 with the key box cover 2 is detached from the guide rail 8. In this embodiment, the movement of the first sliding member 4 is only subject to the friction force of the sliding surface 412, so that the friction force of the first sliding member 4 in the process of moving towards the key box cover 2 in this embodiment is smaller than that of embodiment 1, which is beneficial for the smooth and smooth movement of the first sliding member 4 towards the key box cover 2.

Example 4

Fig. 7 shows a sectional view of the mounting of the magnetic lamp and the guide rail of the present embodiment. Referring to fig. 1, 2 and 7 in combination, the present embodiment provides a magnetic lamp, which includes a lamp body 9 and a power box 7 connected to the lamp body 9, and a key box assembly having the same structure as that of embodiment 1 is installed in the power box 7.

The first sliding piece 4 in the key box assembly protrudes out of the power box 7 towards the top of the guide rail 8, and the second sliding piece 5 protrudes out of the power box 7 towards the side face of the guide rail 8 and is clamped with the guide rail 8. The magnetic lamp is connected with an external guide rail in a clamping way through the key box component.

Pressing the pressing portion 31 protruding from one end of the power box 7 causes the key 3 to move against the elastic force of the spring 6. With the movement of the key 3, the first slider 4 moves in the direction of the key case cover 2 by the first guide portion 33 and the first slider portion 41 and abuts against the top of the guide rail 8. At this time, the first slider 4 gives an upward force to the top of the guide rail 8, and the magnetic lamp mounted with the power supply box 7 overcomes the magnetic force and generates a certain distance from the top of the guide rail 8 under the force. At the same time, the second slider 5 is retracted in the direction of the inside of the key case 1 by the action of the second guide portion 34, the second slider 51, the guide bar 111, and the third slider 53, and the engagement state with the guide rail 8 is released.

Therefore, the magnetic lamp provided in this embodiment can overcome the magnetic force of the guide rail 8 while releasing the engagement with the guide rail 8 by pressing the pressing portion 31, and can be easily detached from the guide rail 8.

The foregoing is merely illustrative and explanatory of the utility model as it is described in more detail and is not thereby to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and that these obvious alternatives fall within the scope of the utility model.
