Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a magnifying glass lamp whose working status is controlled by a flip cover. Background Technology

[0002] A magnifying glass lamp is a special type of lamp that combines magnification and illumination functions. It can be widely used in product inspection and assembly in factories, and is also suitable for fields such as medical, beauty, electronics, handicrafts, stamp collecting, and jewelry collecting. Existing magnifying glass lamps generally include a lamp housing, a magnifying glass installed in a ring hole in the lamp housing, and a hinged cover on the rear side of the lamp housing to cover the ring hole. The cover is used to prevent dust from falling onto the magnifying glass when not in use and affecting the normal operation of the magnifying glass lamp next time. In the current magnifying glass lamp, it is generally necessary to open the cover first, and then open the light source component of the magnifying glass lamp through another control component. After use, it is also necessary to turn off the light and close the cover. The magnifying glass lamp is relatively cumbersome to use and has room for improvement. Utility Model Content

[0003] The present invention aims to overcome the defects in the prior art by providing a magnifying glass lamp whose working state can be controlled by flipping the cover. It combines the flipping action of the magnifying glass lamp with the light source switching action. The opening and closing action of the flipping cover directly controls the light source component to turn on or off, which greatly simplifies the use of the magnifying glass lamp and effectively avoids the problem of forgetting to close the flipping cover after using the magnifying glass lamp.

[0004] To achieve the above objectives, this utility model provides a magnifying glass lamp whose working state is controlled by a flip cover, including an annular lamp housing, a magnifying glass installed in an annular hole in the lamp housing, and a flip cover hinged to the rear side of the lamp housing to cover the annular hole. The lamp housing is hollow and has a mounting cavity, and a light source assembly is provided in the mounting cavity.

[0005] It also includes a pressure plate and a control switch for controlling the working state of the light source assembly, the control switch including a top shaft that always has an upward spring-up tendency to keep the switch in the normally open state;

[0006] The lamp housing has a rotating opening on its upper rear side that communicates with the mounting cavity. Inside the mounting cavity, below the rotating opening, there is a sliding channel for mounting the pressure plate to constrain its vertical upward and downward movement. The top shaft of the control switch is vertically extended and positioned directly below the pressure plate.

[0007] The flip cover includes a rotating lug placed within a rotating opening;

[0008] When the flip cover is closed, the control switch is in the open state where the top shaft pops up, and the light source assembly does not emit light at this time;

[0009] When the flip cover is in the open state, the top shaft of the control switch is pressed downward by the rotating lug to close the control switch, at which time the light source assembly emits light.

[0010] A further configuration is provided: a support plate is provided below the lower port of the sliding channel within the mounting cavity of the lamp housing, and a spring is provided between the support plate and the pressure plate;

[0011] The control switch is located below the shelf, and its top shaft extends through the shelf into the sliding channel.

[0012] The rotating ear is further configured such that its end has a first working surface that abuts against the pressure plate plane in the closed state and a second working surface that abuts against the pressure plate plane in the open state, wherein the distance between the first working surface and the flip cover rotation axis is less than the distance between the second working surface and the flip cover rotation axis.

[0013] It is further configured that the angle between the first working surface and the second working surface is an acute angle.

[0014] The pressure plate is further configured such that its lower surface is provided with a pressing slope for pressing against the top shaft.

[0015] A further configuration is made such that the front side of the rotating port is connected to the annular hole of the lamp housing.

[0016] A further feature is provided: the front side of the flip cover, opposite to the rotating ear, is provided with an upwardly raised handle structure.

[0017] Compared with the prior art, this utility model has a simple and reasonable structure, which combines the flip-cover action during the use of the magnifying glass lamp with the light source switch action. The opening and closing action of the flip-cover directly controls the light source component to turn on or off, which greatly simplifies the use of the magnifying glass lamp and also effectively avoids the problem of forgetting to close the flip-cover after the magnifying glass lamp is used.

[0023] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0024] This utility model relates to a magnifying glass lamp controlled by a flip cover 30 and a switch 50. Figure 1 , Figure 2 and Figure 3 As shown, the lamp includes an annular lamp housing 10, a magnifying glass 20 installed in an annular hole 11 of the lamp housing 10, and a hinged cover 30 that is hinged to the rear side of the lamp housing 10 to cover the annular hole 11. The lamp housing 10 is hollow and has a mounting cavity in which a light source assembly (not shown) is installed, and a control switch 50 for controlling the light source assembly (not shown) to turn on or off. This patent enables the control switch 50 to operate in conjunction with the opening and closing of the cover 30, so that the light source assembly (not shown) is powered on and emits light or is powered off and does not emit light, thereby greatly simplifying the use of the magnifying glass lamp.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the lamp housing 10 has a rotating opening 12 on its upper rear side that communicates with the mounting cavity. A slide plate extends downwards from the outer periphery of the rotating opening 12 on the top wall of the mounting cavity inside the lamp housing 10. The slide plates cooperate to form a sliding channel 13 for mounting the pressure plate 40 and constraining its vertical upward and downward movement. A support plate 14 is provided below the lower end of the sliding channel 13 within the mounting cavity of the lamp housing 10. A spring 60 is provided between the support plate 14 and the pressure plate 40. The control switch 50 is fixedly mounted... Located below the shelf 14, it includes a top shaft 51 that always has an upward tendency to keep the switch in the normally open state. The top shaft 51 extends through the shelf 14 and into the sliding channel 13. The flip cover 30 includes a rotating ear 31 that is placed in and rotatably connected to the rotating opening 12. The flip cover 30 can switch between a closed state and an open state by rotating along the rotation axis via the rotating ear 31. The end of the rotating ear 31 has a first working surface 3 that abuts against the plane of the pressure plate 40 in the closed state. 11. And a second action surface 312 that abuts against the plane of the pressure plate 40 in the open state. The distance between the first action surface 311 and the rotation axis of the flip cover 30 is less than the distance between the second action surface 312 and the rotation axis of the flip cover 30. This allows the flip cover 30 to press the pressure plate 40 downward when it changes from the closed state to the open state, so as to achieve the effect of pressing the control switch 50 to close. When the flip cover 30 is in the closed state, under the action of the spring 60, the pressure plate 40 is located above the top shaft 51 or the force applied by the pressure plate 40 to the top shaft 51 is less than the elastic force of the top shaft 51 itself. Thus, the control switch 50 is in the open state where the top shaft 51 is lifted. At this time, the circuit of the light source component (not shown in the figure) is open and the light source component (not shown in the figure) does not emit light. When the flip cover 30 is in the open state, the top shaft 51 of the control switch 50 is pressed downward by the rotating ear 31 so that the control switch 50 is in the closed state. At this time, the circuit of the light source component (not shown in the figure) is closed and the light source component (not shown in the figure) is powered on and emits light.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the angle between the first working surface 311 and the second working surface 312 at the end of the rotating ear 31 is an acute angle, which allows the flip cover 30 to tilt backward when it is open. At the same time, the pressure plate 40 can push the rotating ear 31 under the action of the spring 60 and the top shaft 51 so that the flip cover 30 can be stably kept in the open state.

[0027] In this embodiment, the lower surface of the pressure plate 40 is provided with a pressing slope 41 for pressing against the top shaft 51.

[0028] In this embodiment, the front side of the flip cover 30, which is opposite to the rotating ear 31, is provided with an upwardly raised handle structure 32. In this way, by inserting a finger into the handle structure 32, the closed flip cover 30 can be easily pulled up to switch the working state.

[0029] In this embodiment, the front side of the rotating port 12 is connected to the annular hole 11 of the lamp housing 10, which can effectively improve the fit between the flip cover 30 and the lamp housing 10 when closed.

[0030] Compared with the prior art, this utility model has a simple and reasonable structure, which combines the flip-cover action during the use of the magnifying glass lamp with the light source switch action. The opening and closing action of the flip-cover directly controls the light source component to turn on or off, which greatly simplifies the use of the magnifying glass lamp and also effectively avoids the problem of forgetting to close the flip-cover after the magnifying glass lamp is used.

[0031] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
