[0031] Example 1

[0032] Reference Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides an adjustment mechanism, which can achieve the effect of adjusting the angle and fixing the lighting housing 103, including, a mounting unit 100, including a mounting plate 101, a connecting arm 102 arranged on the mounting plate 101, a lighting housing 103 arranged on the connecting arm 102, and a connecting component 104 arranged in the connecting arm 102 and connected to the lighting housing 103; an adjustment unit 200, including a pushing component 201 arranged on the connecting arm 102, and a displacement component 202 arranged on the pushing component 201. The mounting plate 101 is movably connected to the inner wall of the cabinet by screws, and is easy to install and replace. Connecting arms 102 are arranged on both sides of the lower end of the mounting plate 101, and a lighting housing 103 is arranged between the two connecting arms 102. The lighting housing 103 can provide light to the cabinet during equipment inspection.

[0033] Specifically, the connecting assembly 104 includes connecting rods 104a arranged on both sides of the lighting housing 103, a movable groove 104b arranged in the connecting arm 102, and a pushing rod 104c on one side of the movable groove 104b. The two sides of the lighting housing 103 are fixedly connected with the connecting rods 104a, and the interior of the connecting arm 102 is provided with a movable groove 104b, and the movable groove 104b is a cylindrical groove. One end of the connecting rod 104a is rotatably connected in the movable groove 104b, so that the lighting housing 103 can be rotated between the two connecting arms 102. One side of the arm 102 is movably connected with a pushing rod 104c, the other end of the pushing rod 104c is movably connected in the movable groove 104b and a circular groove 201a is provided on the other side surface, one end of the connecting rod 104a is movably connected in the circular groove 201a, four groups of connecting blocks 201c are arranged inside the circular groove 201a, four limiting grooves 201d are provided on the outer wall of the connecting rod 104a, and the connecting block 201c is slidably connected to the limiting groove 201d. With such a design, when the connecting rod 104a rotates, the pushing rod 104c will be driven to rotate through the connecting block 201c.

[0034] Further, the displacement assembly 202 includes a rotating shaft 202a arranged on the movable block 201b, a connecting handle 202b arranged on the rotating shaft 202a, and a fixed block 202c arranged on the connecting handle 202b, and also includes a fixed assembly 203, the fixed assembly 203 is arranged on the fixed block 202c, and the fixed assembly 203 includes a back plate 203a arranged on the fixed block 202c, an anti-skid pad 203b arranged on the outer side of the back plate, and a baffle ring 203c arranged in the movable groove 104b; the protective pad is matched with the inner wall of the movable groove 104b, and four groups of movable blocks 201b are arranged on the outside of the push rod 104c, and a fixed block 203a is arranged above the movable block 201b. 2c, and the movable block 201b and the fixed block 202c are both rectangular in shape, and the movable block 201b and the fixed block 202c are both movably connected with the rotating shaft 202a near the two sides, and the two ends of the rotating shaft 202a located on the two sides are rotatably connected with the connecting handles 202b, and the fixed block 202c is provided with a butt plate 203a, which is in an arc shape and matches the inner wall of the movable groove 104b, and the outer side of the butt plate 203a is provided with an anti-skid pad 203b, which is used to increase the friction between the butt plate 203a and the inner wall of the movable groove 104b, and the inner wall of the movable groove 104b is provided with a baffle ring 203c, and one side of the butt plate 203a is in close contact with the movable groove 104b. The other side inner wall of the groove 104b and the other side of the push plate 203a are in close contact with one side of the baffle ring 203c, so that the position of the push plate 203a is restricted, and the push plate 203a cannot move left and right, but can only move toward the inner side of the movable groove 104b. The movement of the push plate 203a is restricted, and the movement range of the fixed block 202c is also restricted. When the push plate 203a, the movable block 201b and one side surface of the fixed block 202c are all in contact with one side of the inner wall of the movable groove 104b, the connecting handle 202b is in a horizontal and vertical state at this time, the push plate 203a is in contact with the inner wall of the movable groove 104b, and the anti-slip pad 203b is affected by the push plate 203a and the movable The pressure applied by the groove 104b causes the groove 104b to deform, thereby increasing the friction between the back plate 203a and the inner wall of the movable groove 104b, the purpose of which is to prevent the back plate 203a from accidentally moving or sliding, and to ensure that the push rod 104c remains stable in a specific position at this time. A fixing ring 204a is provided on the inner wall of the baffle ring 203c, and a first spring 204b is fixedly connected to a surface of one side of the fixing ring 204a, and the other end of the first spring 204b is fixedly connected to one end of the push rod 104c, so that when the push rod 104c moves, the first spring 204b applies a thrust, and the first spring 204b always applies a stretching elastic force to one side on the push rod 104c.

[0035] When in use, the mounting plate 101 is fixed to the inner wall of the cabinet by screws, and the lighting housing 103 is fixed in the cabinet. When the light in the cabinet is not very good during equipment maintenance, and the angle of the lighting housing 103 needs to be adjusted to obtain sufficient lighting, the lighting housing 103 can be rotated. At this time, the first spring 204b is in an extended state, and always applies a thrust to one side to the push rod 104c, so that the side surfaces of the abutment plate 203a, the movable block 201b and the fixed block 202c are all in contact with one side of the inner wall of the movable groove 104b. This will make the four sets of abutment plates 203a close to the inner wall of the movable groove 104b, and the friction force generated by the anti-skid pad 203b will cause the push rod 104c to be unable to rotate. The inability of the push rod 104c to rotate will cause the connecting rod 104a connected through the connecting block 201c to be unable to rotate, so that the lighting housing 103 cannot rotate at this time. We can press the push rod 104c on the outer side of the connecting arm 102 at the same time. After pressing hard, the other end of the push plate will apply pressure to the other side of the first spring 204b, so that the first spring 204b The push rod 104c drives the connecting block 201c to slide in the limiting groove 201d, and the push rod 104c drives the movable block 201b to move to the other side. Since the position of the fixed block 202c is limited and can only move vertically up and down, the lower end of the connecting handle 202b moves, while the upper end cannot move synchronously, which will cause the connecting handle 202b to rotate counterclockwise around the rotating shaft 202a, thereby driving the fixed block 202c to move vertically downward, thereby driving the outer surface of the abutment plate 203a to come off. When the angle of the lighting housing 103 needs to be fixed, the push rod 104c can be loosened, and under the action of the tension force of the first spring 204b, a thrust in one direction is applied to the push rod 104c, thereby driving the movable block 201b to reset and driving the abutment plate 203a to fit the inner wall of the movable groove 104b again, thereby achieving the problem of adjusting the angle of the lighting housing 103 at will.

[0036] Example 2

[0037] Reference Figure 3 to Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides an adjustment unit 200 of the adjustment mechanism, which solves the problem that after the push rod is pushed and then released, the push rod will rebound and cannot be separated from the push rod to adjust the angle of the lighting housing 103, including.

[0038] Furthermore, it also includes a limit assembly 205, the limit assembly 205 is arranged in the circular groove 201a, the limit assembly 205 includes a deformation groove 205a in the circular groove 201a, a rubber ring 205b in the deformation groove 205a, a force ring 205c in the rubber ring 205b, and an extrusion surface 205d arranged on the outer side of the connecting rod 104a;

[0039] The stress ring 205c and the extrusion surface 205d cooperate with each other, and a deformation groove 205a is provided on the inner wall of the circular groove 201a. The deformation groove 205a is an annular groove, and a rubber ring 205b is fixedly connected to the outer side of the inner wall. The rubber ring 205b is made of rubber material, and rubber is a material with good elasticity. Three groups of stress rings 205c are arranged on the inner side of the rubber ring 205b. The stress ring 205c is in a quarter-circular ring shape. When the stress ring 205c is subjected to pressure, the stress ring 205c will transfer the pressure to the rubber ring 205b, so that the rubber ring 205b is deformed, and the stress ring 205c can be in the deformation groove 205a. The connecting rod 104a has an outer wall provided with an extrusion surface 205d, which is arranged around the connecting rod 104a and presents an inclined surface. The extrusion surface 205d is matched with the inner inclined surface of the force ring 205c. The outer surface of the connecting rod 104a is located on the other side of the extrusion surface 205d and is provided with a sliding groove 206a, in which an adjusting ring 206c is slidably connected to the inside thereof. The adjusting ring 206c is elastically connected to the inner wall of the sliding groove 206a by a second spring 206b. The outer side of the adjusting groove is triangular, that is, both sides are inclined.

[0040] When in use, the pressing rod is pushed to move, and the pressing rod will drive the force ring 205c to move, thereby contacting the extrusion surface 205d, and the inner inclined surface of the force ring 205c will be squeezed by the extrusion surface 205d, thereby forcing the force ring 205c to move outward, and the force ring 205c will exert pressure on the rubber ring 205b, so that the rubber ring 205b is deformed to leave space for the force ring 205c, so that the force ring 205c has enough space to cross the critical point of the extrusion surface 205d. When the force ring 205c crosses the extrusion surface 205d, the pressure on the rubber ring 205b disappears and quickly returns to its original state, thereby pushing the force ring 205c to move inward, and the force ring 205c will be limited in the sliding groove 206a, and then it can be released. When the push rod 104c is opened, the elastic force of the first spring 204b will always apply a thrust to the push rod 104c, but the force ring 205c is limited in the sliding groove 206a, and they conflict with each other and cannot move. At this time, the lighting housing 103 can be adjusted in angle. After the adjustment is completed, the pressing rod is pushed again. At this time, the adjusting ring 206c is pushed by the extension elastic force of the second spring 206b, and its other side always fits the inner wall of the sliding groove 206a. The push rod 104c drives the force ring 205c to contact the adjusting ring 206c and is squeezed by the inclined surface of one side of the adjusting ring 206c. Since one side of the adjusting ring 206c has already been against the inner wall of the sliding groove 206a, the adjusting ring 206c cannot move, causing the force ring 205c to move outward. When the force ring 205c passes over the adjusting ring 206c, the push can be released. Under the action of the stretching elastic force of the first spring 204b, the force ring 205c will contact the other side inclined surface of the adjusting ring 206c and exert pressure on the adjusting ring 206c. Since the adjusting ring 206c is only subjected to the stretching elastic force from the second spring 206b at this time, and the elastic force of the second spring 206b is much smaller than the elastic force of the first spring 204b, the force ring 205c will push the adjusting ring 206c to move to one side until one side of the adjusting ring 206c fits the inner wall of the sliding groove 206a. When the adjusting ring 206c fits the inner wall of the sliding groove 206a, the outer edge of the extrusion surface 205d at this time and the outermost edge of the adjusting ring 206c are in contact with each other. The outer corners are in contact and fit together, and the pressure exerted by the force ring 205c on the adjusting ring 206c will be transmitted to the rubber ring 205b, thereby deforming it, and the force ring 205c will pass over the outermost corner of the adjusting ring 206c and contact the extrusion surface 205d again. The force ring 205c has no obstacles and moves quickly to one side under the action of the stretching elastic force of the second spring 206b, driving one side of the movable block 201b to contact the inner wall of the movable groove 104b, so that the abutment plate 203a contacts the inner wall of the movable groove 104b, and the position of the push rod 104c is fixed at this time. Since the connecting block 201c is limited in the limiting groove 201d, the position of the connecting rod 104a is fixed.The effect of fixing the angle of the lighting housing 103 is achieved.

[0041] Example 3

[0042] Reference Figures 5 and 6 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an in-cabinet lighting lamp for cabinet maintenance, which solves the problem of power failure in the cabinet and loss of power to the lighting lamp during maintenance, resulting in no light in the cabinet. It includes the adjustment mechanism in the above embodiment, including a lighting unit 300, including a door-controlled light 301 arranged on the lighting housing 103, a power supply 302 arranged on one side of the lighting housing 103, and an emergency component 303 arranged in the lighting housing 103.

[0043] Specifically, the emergency component 303 includes a circuit board 303a arranged in the lighting housing 103, a battery 303b arranged in the lighting housing 103, and an emergency light 303c arranged on the lighting housing 103. Under normal circumstances, the lighting AC power supply 302 in the cabinet supplies power to the access-controlled light 301. At the same time, the AC power supply 302 is converted into a 12V DC power supply 302 through the transformer and rectifier bridge inside the access-controlled light 301. The 12V DC power supply 302 charges the battery 303b inside the access-controlled light 301, and controls the power on and off of the emergency access-controlled light 301 through an internal relay. During the maintenance process, when the power supply 302 in the cabinet is disconnected, the emergency light 303c circuit is connected, and the emergency light 303c will start working to provide lighting. When the maintenance is completed, the lighting power supply 302 in the cabinet is closed, and the emergency lighting power supply 302 is disconnected again. Because the power supply 302 circuit of the emergency light 303c is inside the access-controlled light 301, and the voltage is lower than the human safety voltage of 36V, there is no risk of electric shock. During non-maintenance periods, when the lighting power supply 302 is powered normally, the relay K1 coil is energized, the lighting circuit is connected, and the emergency lighting circuit is disconnected. At the same time, the AC power supply 302 is converted into a 12V DC power supply 302 through a transformer and a rectifier bridge, and the 12V DC power supply 302 charges the internal battery 303b.

[0044] During use, when the equipment is under maintenance, the lighting power supply 302 circuit is disconnected. At this time, the relay K1 coil is in a non-powered state, the lighting circuit is disconnected, the emergency lighting circuit is connected, and the battery 303b supplies power to the emergency light 303c. This solves the problem that during the maintenance of the equipment, in order to ensure personal safety, the power supply 302 in the cabinet is disconnected, the lighting in the cabinet loses power, and the light in the cabinet is not very good when the equipment in the cabinet is being repaired, which affects work efficiency.
