Description

Technical Field

[0001] The utility model relates to the field of lamps, and more specifically, it relates to a hand-held lamp with a protection structure. Background Technique

[0002] A hand-held lamp is a portable and practical lighting tool, usually composed of a lamp head, a lamp body, a handle, a power source, a control switch and other parts. The lamp head part contains light sources such as bulbs or light-emitting diodes, which can provide bright light.

[0003] However, the current hand-held lamps have poor protection performance. Although there is a lamp shell for protection, in order to achieve good lighting effects, its bulb (the bulb is relatively fragile) is generally flush with the opening of the lamp shell (the flush setting can minimize the scattering and reflection losses of light inside the lamp shell, so that the light emitted by the bulb can be emitted from the lamp shell more directly and efficiently, thereby improving the brightness and clarity of lighting). When impacted (mainly the impact during dropping), it is extremely easy to break, thus affecting the service life of the hand-held lamp.

[0004] Therefore, in order to solve the above technical problems, this application proposes a hand-held lamp with a protection structure. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a hand-held lamp with a protection structure.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hand-held lamp with a protection structure, including a protection shell, the protection shell includes a mutually connected shell A and shell B, a battery is installed inside shell A near the end part, and an elastic telescopic component for pushing the bulb on the lamp base to the opening part of shell B is installed in front of the battery in the protection shell. When not in use, the bulb can also be retracted into shell B, and the battery supplies power to the lamp base through wires.

[0007] Preferably, the elastic telescopic component includes a plurality of springs fixed on the surface of the battery in a circumferential array, and a transverse groove opened on the outer side wall of shell A near the opening part. The head of the spring is installed with an elastic support plate, the surface of the elastic support plate is fixed to the back of the lamp base, the top end of the elastic support plate is fixedly connected with a vertical plate that can move along the transverse groove, the surface of the vertical plate is rotationally connected with a rotating plate through a bearing, and a stop block for restricting the position of the rotating plate is also arranged on the outer side wall of shell A.

[0008] Preferably, a groove for inserting the rotating plate is formed on the stopper, and a switch groove with an elastic switch installed therein is formed on the inner surface of the groove. The elastic switch protrudes from the switch groove in a non-extruded state, and at this time, the lamp is in an on state. On the contrary, after the elastic switch is squeezed by the rotating plate and contracts into the switch groove, the lamp is turned off.

[0009] Preferably, a telescopic rod is installed on the inner surface of the housing B, and the head of the telescopic rod is fixed to the back of the bulb to maintain the linear movement of the bulb.

[0010] Preferably, a circular through groove for the wire to pass through is formed in the central part of the elastic support plate to prevent the wire from being wound around the spring.

[0011] Preferably, a covering layer made of rubber is bonded to the outer surface of the protective housing to prevent the protective housing from being damaged when it falls.

[0012] Preferably, a handle for easily holding the lamp is fixedly connected to a part of the outer side wall of the housing A far away from the opening, which is convenient for the user to hold the lamp.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. The present utility model jacks up the lamp holder and the bulb through the elastic telescopic assembly, so that the bulb can be pushed to the opening part of the housing B for normal use of the lamp. When not in use, the lamp holder and the bulb can also be retracted into the housing B to protect the bulb from being damaged, thus solving the problem that the bulb is easily damaged in the background technology.

[0015] 2. A covering layer made of rubber is bonded to the outer surface of the housing of the present utility model. In this way, when the protective housing falls, the rubber covering layer buffers the impact force to prevent the protective housing from being damaged and deformed.

[0016] 3. The design of the switch of the present utility model integrates the switch operation of the lamp with the telescopic operation of the bulb, which can avoid the situation that the user forgets to retract the bulb into the housing when not using the lamp. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0024] As Figures 1-5 shown, this utility model provides a handheld lamp with a protective structure, including a protective housing 1, the protective housing 1 includes a housing A 101 and a housing B 102 that are interconnected, a battery 3 is installed near the end inside the housing A 101, and an elastic telescopic assembly 4 that pushes the light bulb 6 on the lamp socket 5 to the opening part of the housing B 102 is installed in front of the battery 3 in the protective housing 1, and the battery 3 supplies power to the lamp socket 5 through a wire 7.

[0025] During use, the lamp socket 5 and the light bulb 6 are pushed up through the elastic telescopic assembly 4 to push the light bulb 6 to the opening part of the housing B 102 for normal use of the lamp. When not in use, the lamp socket 5 and the light bulb 6 can also be retracted into the housing B 102, thereby protecting the light bulb 6 to avoid damage to the light bulb 6.

[0026] The following is the specific structure of the elastic telescopic component 4: The elastic telescopic component 4 includes a plurality of springs 41 fixed on the surface of the battery 3 and arranged in a circumferential array, and a transverse groove 43 opened on the outer side wall of the housing A101 near the opening. The head of the spring 41 is equipped with an elastic support plate 42. The surface of the elastic support plate 42 is fixed to the back surface of the lamp socket 5. The top of the elastic support plate 42 is fixedly connected to a vertical plate 44 that can move along the transverse groove 43. The surface of the vertical plate 44 is rotatably connected to a rotating plate 45 through a bearing. A stopper 46 for restricting the position of the rotating plate 45 is also provided on the outer side wall of the housing A101. An expansion and contraction rod 11 is installed on the inner surface of the housing B102, and the head of the expansion and contraction rod 11 is fixed to the back of the light bulb 6. That is, in the normal state, the spring 41 has no obstruction, and the elastic support plate 42 is supported to the maximum height, so as to push the light bulb 6 on the lamp socket 5 to the opening part of the housing B102. When the lamp is not needed, by pulling the vertical plate 44 to move away from the housing B102, the vertical plate 44 moves along the inside of the transverse groove 43, and the vertical plate 44 also drives the movement of the elastic support plate 42, so as to retract the light bulb 6 on the lamp into the housing B102 to avoid its damage, and at the same time compress the spring 41. After the contraction is completed, rotate the rotating plate 45 and press it against the surface of the stopper 46 to stabilize the positions of the vertical plate 44 and the light bulb 6. The expansion and contraction of the expansion and contraction rod 11 will also be driven during the telescopic process of the light bulb 6, so as to maintain the linear movement of the light bulb 6 and prevent it from contacting the inner wall of the housing B102, which will affect its normal telescopic operation (the friction with the inner wall of the housing B102 is relatively large, which will affect the operation and cause damage to the light bulb 6 at the same time).

[0027] Furthermore, a handle 13 for conveniently holding the lamp is fixedly connected to the outer side wall of the housing A101 far away from the opening. A rubber - material covering layer is adhesively bonded to the outer surface of the protective housing 1. In this way, when the protective housing 1 drops, the rubber covering layer buffers the impact force to avoid damage and deformation of the protective housing 1. A circular through - groove 12 for the power line 7 to pass through is opened at the central part of the elastic support plate 42. In this way, the wire 7 can be restricted to the central part of the housing A101, which can prevent it from winding around the spring 41 and affecting the normal use of the lamp.

[0028] Moreover, a groove 8 for inserting the rotating plate 45 is formed in the stopper 46, and a switch groove 9 with an elastic switch 10 installed therein is formed on the inner surface of the groove 8. The elastic switch 10 protrudes from the switch groove 9 in a non-extruded state, and at this time the lamp is in the on state. When the rotating plate 45 abuts against the surface of the stopper 46, it is pushed into the groove 8, thereby restricting its rotation (under the elastic force of the spring 41, it is difficult to leave the groove 8), preventing it from sliding off the stopper 46. At the same time, when it enters the groove 8, it will squeeze the elastic switch 10, and the elastic switch 10 contracts into the switch groove. A groove 8 for inserting the rotating plate 45 is formed in the stopper 46, and a switch groove 9 with an elastic switch 10 installed therein is formed on the inner surface of the groove 8. The elastic switch 10 protrudes from the switch groove 9 in a non-extruded state, and at this time the lamp is in the on state. On the contrary, after the elastic switch 10 is squeezed by the rotating plate 45 and contracts into the switch groove 9, the lamp is turned off. Such a design of the switch integrates the switch operation of the lamp with the telescopic operation of the bulb 6, and can prevent the situation that the user forgets to retract the bulb 6 into the housing when not using the lamp.

[0029] It should be noted that the elastic switch 10 is a common mechanically triggered electronic component, mainly composed of a metal spring, a movable contact and a fixed contact. In the natural state, the metal spring is not compressed, the movable contact is separated from the fixed contact, and the circuit is in an open state. When pressed by an external force, the metal spring is compressed, prompting the movable contact to contact the fixed contact, thereby closing the circuit. After the external force disappears, the metal spring returns to its original state by its own elasticity, the movable contact is separated from the fixed contact, and the circuit is disconnected again. In the spring switch of the present invention, only the positions of the movable contact and the fixed contact are reversed, so that when the metal spring is not compressed, the movable contact intersects with the fixed contact, and when the metal spring is compressed, the movable contact is separated from the fixed contact.

[0030] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the instructions in the accompanying drawings and the above description; however, any slight changes, modifications and equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
