Description

Technical Field

[0001] This utility model relates to the field of flashlights, specifically to a flashlight with a display screen. Background Technology

[0002] A flashlight is a portable, handheld lighting tool. Its core function is to use its own power source (usually a battery) to power a light bulb or LED light source, and then use a reflector (reflector cup) and lens to focus the light into a beam to illuminate the area in front or a specific area. With the development of technology, the structure of flashlights has also improved, resulting in flashlights with displays that can show real-time information such as the current time, remaining battery power, and lighting mode.

[0003] When maintenance personnel repair lighting fixtures, the fixtures are often unable to provide illumination, so a flashlight is needed to provide continuous lighting to complete the repair work. During repairs, the flashlight must be accurately aimed at the repair location to achieve the desired illumination. To achieve this, maintenance personnel typically either hold the flashlight by hand or place it at a high position. Holding the flashlight by hand means the maintenance personnel can only perform repairs with one hand, which is inefficient and increases the risk of danger. Placing the flashlight at a high position limits the lighting effect, similarly affecting repair efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flashlight with a display screen that utilizes on-site magnetic metal objects to improve maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a main body, with a lamp head at the front end and a button at the rear end to control the lamp head's light emission. A display screen is located on the side of the main body. A magnetic platform formed by a cross-section is located above the rear end of the main body. The magnetic platform includes a magnetic base and a magnetic support connecting the magnetic base and the platform. The upper surface of the magnetic base has a main magnet for attracting magnetic metal objects. The magnetic base has an initial state and an adjustable state. In the initial state, the magnetic base is in contact with the magnetic platform. In the adjustable state, the magnetic base separates from the platform and its angle with the magnetic support is adjusted by swinging.

[0006] By adopting the above technical solution, upon arrival at the repair site, if there are magnetic metal objects (such as iron cabinets, iron doors, etc.) near the repair location, the flashlight can be attached to the magnetic metal object using a magnetic holder for illumination. This frees the repair personnel's hands from holding the flashlight, thereby improving repair efficiency and safety. If there is a deviation between the illuminated position of the attached flashlight and the repair location, the magnetic holder can be switched from its initial state to an adjustment state to adjust the angle between the magnetic holder and the flashlight, correcting the deviation and ensuring the illumination effect.

[0007] The present invention is further configured such that: the lower end face of the magnetic base is provided with a bracket mounting groove along the front-back direction; the magnetic platform is provided with a bracket storage groove along the front-back direction; the upper end of the magnetic bracket is hinged to the middle of the bracket mounting groove; and the lower end is hinged to the front end of the bracket storage groove.

[0008] By adopting the above technical solution, the magnetic bracket is hinged to the magnetic base and the magnetic platform respectively, so that the magnetic bracket can unfold relative to the magnetic platform and adjust the included angle with the magnetic base. At the same time, the middle of the bracket mounting groove is selected as the hinge position with the magnetic base, and the front end of the bracket storage groove is selected as the hinge position with the magnetic platform. This makes the hinge point of the magnetic bracket closer to the center of gravity of the magnetic base and the main body, thereby improving the stability of the magnetic base in the adjustment state.

[0009] The present invention is further configured such that: the upper left and right sides of the upper end of the magnetic bracket are respectively provided with upper hinge shafts that are hinged to the magnetic base, and one of the upper hinge shafts extends to the outside of the magnetic base and is provided with an adjusting rod. The adjusting rod is provided with an adjusting nut that is threaded to it. When the adjusting nut is tightened to the side of the magnetic base, the relative position of the magnetic base and the magnetic bracket is locked.

[0010] By adopting the above technical solution, when the magnetic base is in the adjustment state, the magnetic base can be adjusted by swinging to adjust the angle between itself and the magnetic bracket until the lamp head is aligned with the maintenance position. Then, the adjusting nut and the adjusting rod lock the relative position of the magnetic base and the magnetic bracket, thereby achieving stable directional lighting.

[0011] The present invention is further configured such that: the lower end face of the magnetic base is provided with four upper positioning magnets arranged in a rectangular shape, and the magnetic platform is provided with lower positioning magnets that correspond one-to-one with the upper positioning magnets; when the lower end face of the magnetic base is in contact with the magnetic platform, the upper positioning magnets and the lower positioning magnets attract each other.

[0012] By adopting the above technical solution, the upper positioning magnet and the lower positioning magnet attract each other, so that the magnetic holder can stably maintain its initial state.

[0013] The present invention is further configured such that the left and right sides of the magnetic base are exposed outside the main body and are used to manually separate the magnetic base from the magnetic platform.

[0014] By adopting the above technical solution, the left and right sides of the magnetic base are designed to be exposed outside the main body as force application sides, which makes it easier for fingers to exert force and overcome the magnetic force between the upper and lower positioning magnets to separate the magnetic base from the magnetic platform.

[0015] The present invention is further configured such that: the lower left and right sides of the lower end of the magnetic bracket are respectively provided with lower hinge shafts that are hinged to the main body; each of the lower hinge shafts is provided with an assisting cavity at the connection point with the magnetic bracket; and an assisting spring is sleeved inside the assisting cavity of the lower hinge shaft, which is compressed between the assisting cavity and the bracket storage groove and resets the magnetic bracket upward.

[0016] By adopting the above technical solution, after the magnetic base is separated from the magnetic platform, the assist spring quickly switches the magnetic base from the initial state to the adjustment state, making the operation more convenient.

[0017] The present invention is further configured such that: the front end face of the main body relative to the magnetic platform serves as the positioning plane; the positioning plane is provided with a front positioning magnet; the magnetic bracket is provided with a rear positioning magnet corresponding to the front positioning magnet; when the magnetic base is in the adjustment state, the magnetic bracket is in contact with the positioning plane, and the front positioning magnet and the rear positioning magnet attract each other.

[0018] By adopting the above technical solution, the magnetic bracket unfolds quickly under the action of the assist spring until it abuts against the positioning plane, guiding the maintenance personnel to complete the state transition and enabling the maintenance personnel to understand the usage method without realizing it. At the same time, the front positioning magnet and the rear positioning magnet attract each other, so that the magnetic bracket can stably maintain the adjustment state.

[0019] The present invention is further configured such that the magnetic platform is located on the other side of the main body opposite the display screen.

[0020] By adopting the above technical solution, the display screen is placed on the opposite side of the main body, so that the display screen faces the maintenance personnel after it is magnetically attached to a magnetic metal object on site, making it easier to understand the flashlight information.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] like Figure 1 — Figure 8As shown, this utility model discloses a flashlight with a display screen, including a main body 1. A lamp head 2 is located at the front end of the main body 1, and a button 3 at the rear end of the main body 1 for controlling the light emitted by the lamp head 2. A display screen 4 is located on the side of the main body 1. A magnetic platform 11, formed by a cross-section, is located above the rear end of the main body 1. The magnetic platform 11 has a magnetic base 12 and a magnetic bracket 13 connecting the magnetic base 12 and the magnetic platform 11. A main magnet 121 is located on the upper surface of the magnetic base 12 to attract magnetic metal objects. The magnetic base 12 has an initial state and an adjustment state. When the magnetic base 12 is in the initial state, it is in contact with the magnetic platform 11. When the magnetic base 12 is in the adjustment state, it is separated from the magnetic platform 11 and the angle between the magnetic base 12 and the magnetic bracket 13 is adjusted by swinging. After arriving at the repair site, if there is a magnetic metal object (such as an iron cabinet or iron door) near the repair location, the flashlight can be attracted to the magnetic metal object through the magnetic base 12 for illumination, freeing the repair personnel's hands from holding the flashlight, thereby improving repair efficiency and safety. If there is a deviation between the illumination position of the attracted flashlight and the repair position, the magnetic base 12 can be switched from the initial state to the adjustment state, and the angle between the magnetic base 12 and the flashlight can be adjusted to correct the deviation, thereby ensuring the illumination effect.

[0032] The lower end face of the magnetic base 12 is provided with a bracket mounting groove 122 along the front-to-back direction, and the magnetic platform 11 is provided with a bracket storage groove 111 along the front-to-back direction. The upper end of the magnetic bracket 13 is hinged to the middle of the bracket mounting groove 122, and the lower end is hinged to the front end of the bracket storage groove 111. The magnetic bracket 13 is hinged to the magnetic base 12 and the magnetic platform 11 respectively, so that the magnetic bracket 13 can unfold relative to the magnetic platform 11 and adjust the included angle with the magnetic base 12. At the same time, the middle of the bracket mounting groove 122 is selected as the hinge position with the magnetic base 12, and the front end of the bracket storage groove 111 is selected as the hinge position with the magnetic platform 11, so that the hinge point of the magnetic bracket 13 is closer to the center of gravity of the magnetic base 12 and the main body 1, thereby improving the stability of the magnetic base 12 in the adjustment state.

[0033] The upper left and right sides of the magnetic bracket 13 are respectively provided with upper hinge shafts 131 that are hinged to the magnetic base 12. One of the upper hinge shafts 131 extends to the outside of the magnetic base 12 and is provided with an adjusting rod 132. The adjusting rod 132 is provided with an adjusting nut 133 that is threaded to it. When the adjusting nut 133 is tightened on the side of the magnetic base 12, the relative position of the magnetic base 12 and the magnetic bracket 13 is locked. When the magnetic base 12 is in the adjustment state, the magnetic base 12 can adjust the angle between itself and the magnetic bracket 13 by swinging until the lamp head 2 is aligned with the maintenance position. Then, the adjusting nut 133 and the adjusting rod 132 lock the relative position of the magnetic base 12 and the magnetic bracket 13, thereby achieving stable directional lighting.

[0034] The lower end face of the magnetic base 12 is provided with four upper positioning magnets 123 arranged in a rectangular shape, and the magnetic platform 11 is provided with lower positioning magnets 112 corresponding to the upper positioning magnets 123. When the lower end face of the magnetic base 12 is attached to the magnetic platform 11, the upper positioning magnets 123 and the lower positioning magnets 112 attract each other. The attraction between the upper positioning magnets 123 and the lower positioning magnets 112 enables the magnetic base 12 to stably maintain its initial state.

[0035] The left and right sides of the magnetic base 12 are exposed outside the main body 1 and are used to manually separate the magnetic base 12 from the magnetic platform 11. Designing the left and right sides of the magnetic base 12 as force-applying sides 124 exposed outside the main body 1 makes it easier to apply force with fingers to overcome the magnetic force between the upper positioning magnet 123 and the lower positioning magnet 112 and separate the magnetic base 12 from the magnetic platform 11.

[0036] The lower left and right sides of the magnetic bracket 13 are respectively provided with lower hinge shafts 134 that are hinged to the main body 1. Each lower hinge shaft 134 is provided with an assist cavity 135 at the connection between it and the magnetic bracket 13. An assist spring 136 is sleeved inside the assist cavity 135 of the lower hinge shaft 134, which is compressed between the assist cavity 135 and the bracket storage groove 111 and resets the magnetic bracket 13 upward. After the magnetic seat 12 is separated from the magnetic platform 11, the assist spring 136 quickly switches the magnetic seat 12 from the initial state to the adjustment state, making the operation more convenient.

[0037] The front face of the main body 1 relative to the magnetic platform 11 serves as the positioning plane 113. The positioning plane 113 is provided with a front positioning magnet 114, and the magnetic bracket 13 is provided with a rear positioning magnet 137 corresponding to the front positioning magnet 114. When the magnetic base 12 is in the adjustment state, the magnetic bracket 13 is in contact with the positioning plane 113, and the front positioning magnet 114 and the rear positioning magnet 137 are attracted to each other. The magnetic bracket 13 is quickly extended under the action of the assist spring 136 until it abuts against the positioning plane 113, guiding the maintenance personnel to complete the state transition and enabling the maintenance personnel to understand the usage method without realizing it. At the same time, the front positioning magnet 114 and the rear positioning magnet 137 are attracted to each other, so that the magnetic base 12 can stably maintain the adjustment state.

[0038] The magnetic platform 11 is located on the other side of the main body 1 opposite to the display screen 4. The display screen 4 is set on the other side of the main body 1 opposite to the display screen 4, so that the display screen 4 faces the maintenance personnel after being attracted to the magnetic metal object on site by the magnetic base 12, making it easy to understand the flashlight information.

[0039] The following is a brief description of how to use the above device:

[0040] like Figure 3As shown, when the flashlight is being carried, the upper positioning magnet 123 and the lower positioning magnet 112 attract each other, and the magnetic base 12 is stably kept in the initial state of being attached to the magnetic platform 11. Most of the magnetic bracket 13 is stored in the bracket storage slot 111. When needed, the magnetic base 12 can be directly attached to the magnetic metal object on site, and it can be attracted to the magnetic metal object on site by the main magnet 121, freeing the repair personnel's hands from holding the flashlight, thereby improving repair efficiency and repair safety.

[0041] like Figure 5 As shown, if there is a deviation between the illumination position of the flashlight after adsorption and the maintenance position, the maintenance personnel hold the main body with one hand and press the force application side 124 of the magnetic base 12 with the thumb and forefinger of the other hand respectively. After overcoming the magnetic force between the upper positioning magnet 123 and the lower positioning magnet 112, the magnetic base 12 is separated from the magnetic platform 11. After separation, the assist spring 136 returns the magnetic bracket 13 upward until the magnetic bracket 13 is in contact with the positioning plane 113, the front positioning magnet 114 and the rear positioning magnet 137 are attracted, and the magnetic base 12 is stably maintained in the adjustment state. The magnetic base 12 is directly attached to the magnetic metal object on site. The angle between the magnetic base 12 and the magnetic bracket 13 can be adjusted by swinging until the lamp head 2 is opposite to the maintenance position. Then, the adjusting nut 133 is tightened to lock the relative position of the magnetic base 12 and the magnetic bracket 13, thereby achieving stable directional lighting.

[0042] After use, remove the magnetic base 12 from the magnetic metal object on site, loosen the adjusting nut 133, press the magnetic base 12 and the magnetic bracket 13 to overcome the tension of the magnets between the front positioning magnet 114 and the rear positioning magnet 137 and the spring force of the assist spring 136, until the magnetic base 12 adheres to the magnetic platform 11 and the upper positioning magnet 123 and the lower positioning magnet 112 attract each other, returning to the original position.
