Description

Technical Field

[0001] The utility model relates to the technical field of lamps. Background Art

[0002] In order to free up the hands of the user to work, the existing lamp body (such as a flashlight or a work light) is usually positioned on a certain component in the application scenario through accessories such as a bracket, or is then fixed to the user's head or waist through a belt connected to the bracket, thereby bringing great convenience to the user.

[0003] However, looking at this type of lamp, the connection between the main body and the bracket is often a plug-in connection. For example, a pen clip is configured on the outer shell of the lamp main body, and the pen clip is inserted into the slide groove of the bracket. However, the addition of the pen clip not only increases the cost of the lamp main body, but also causes inconvenience in assembly. At the same time, due to the elasticity of the pen clip, it becomes difficult to remove the lamp main body from the bracket.

[0004] For another example, a clamp is added to the main body of the lamp, the clamp includes a clamp seat and a deformable clamp ring provided on one side of the clamp seat, the deformable clamp ring has an intrusion-type opening for radial entry of the main body of the lamp and the opening size is smaller than the inner cavity radius of the clamping position, the edge of the clamp seat is provided with mutually opposing sliders; the bracket is provided with a slide groove for the sliders to slide in. Obviously, such a lamp also has the defect of inconvenient assembly and disassembly between the clamp and the main body of the lamp.

[0005] For another example, a cavity with at least two ends passing through is directly formed on the bracket, and openings passing through the two ends are formed on the side wall of the cavity, and the lamp body is inserted into the cavity along the two ends of the cavity. Although the structure is simple, since there is no guiding structure during the insertion process, it is still impossible to ensure the rapid insertion of the lamp body, and it is easy to cause misoperation during blind insertion. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a lamp which is convenient for quickly assembling and disassembling the lamp body from the bracket in view of the current status of the prior art.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lamp, including a lamp body and a bracket, the lamp body also includes a cylindrical shell and a light source part, the bracket has a first space with at least two ends passing through, the shell can be inserted into the first space along the two end directions of the first space, and is characterized in that: the shell includes a first shell part located at the insertion end and a second shell part subsequent to the first shell part, wherein the outer diameter of the first shell part is smaller than the outer diameter of the second shell part, and the first shell part is clearance-fitted with the first space, and the second shell part can be rotatably connected with the bracket after interference fit with the first space.

[0008] In the above solution, a further improvement is that the housing is further provided with a limiting portion, and when the second housing portion is inserted into the working position in the first space, the limiting portion abuts against an end surface of the first space, and the end surface corresponds to the insertion end of the second housing portion. That is, the limiting portion can effectively prevent the lamp body from being over-inserted, and after the lamp body is quickly inserted, it can ensure that the lamp body is in a suitable normal working position relative to the bracket in a timely manner.

[0009] In order to provide a better guiding effect during the plug-in connection process, a second space connected to the first space is provided on the bracket at at least one end of the first space, and the inner diameter of the second space is larger than the inner diameter of the first space to form a guiding cavity. With the help of the second space, the insertion of the first housing part can be guided for the first time, making the insertion of the lamp body smoother. Even if the lamp body is blindly inserted, it can be easily guided to the correct insertion position to avoid misoperation.

[0010] In order to further ensure smooth mating connection, it is preferred that the second space is smoothly connected to the first space.

[0011] In the above scheme, in order to allow the spatial sizes of the first and second spaces to be adaptively changed during the plug-in connection process, a channel is provided on the side wall of the first space, which penetrates the thickness thereof and extends axially to the second space, so that an opening is formed on the side walls of the first space and the second space together, which can increase the inner diameter of the first space and / or the second space during the insertion of the lamp body. By utilizing this opening, the side walls of the first and second spaces have a certain elasticity, which is more conducive to the rapid insertion of the lamp body and can increase the clamping force after insertion into place.

[0012] Preferably, the inner diameter of the second space is larger than the outer diameter of the second housing portion, so that during blind insertion, even when the second housing portion and the second space are not aligned, they can be guided to the correct insertion position.

[0013] Preferably, the inner diameter of the second space is larger than the outer diameter of the second shell portion by Y, and Y≥0.5 mm, so as to ensure the reference effect while avoiding excessive shaking of the second shell portion in the second space.

[0014] Preferably, the axis of the light source part is perpendicular to the axis of the housing, so that when the lamp body rotates, it is beneficial for the light to be emitted at a desired angle.

[0015] In the above solutions, the outer diameter of the second shell portion is X larger than the inner diameter of the first space, and the value range of X is: 0<X≤1.5mm, ensuring that the two can rotate relative to each other and the lamp body can be positioned at a desired angle.

[0016] Preferably, the value range of X is: 0.5mm≤X≤1.5mm, at which time the tightness of the two is more appropriate and the use is more convenient.

[0017] Compared with the prior art, since the utility model designs the outer shell of the lamp body into a first shell part and a second shell part with different outer diameters, the first shell part at the insertion end cooperates with the clearance of the first space, which can play a guiding role during insertion, so that the insertion end of the lamp body can be quickly inserted into the first space, and the subsequent second shell part can be quickly guided into the first space, and by means of the interference fit between the second shell part and the first space, the risk of the lamp body accidentally detaching from the bracket after installation will not occur, and such a structure can guide the lamp body to the correct position even if the user performs a blind insertion action, thereby reducing the occurrence of misoperation. Therefore, the utility model has the advantages of simple overall structure, convenient and fast disassembly and assembly, and convenient and reliable rotation after installation.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] In the description of the following embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "axial", "circumferential", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0025] like Figures 1 to 5 The figures are schematic diagrams of preferred embodiments of the present application. The lamp includes a lamp body 10 and a bracket 20. The lamp body 10 includes a cylindrical shell 1 and a light source part 2. The lamp body 10 in the figure is preferably a flashlight, but other cylindrical working lights can also be used. The lamp body 10 is first inserted into the bracket 20 and then fixed to the installation surface in the use environment through the bracket 20. Or as Figure 4 As shown, a headband 30 is installed on the bracket 20, and the headband 30 is tied or sleeved on the user's head or waist to free the user's hands and facilitate the user's operation.

[0026] Specifically, the bracket 20 includes a base 201 that can be attached to a corresponding part of the human body (according to the prior art, the base 201 is provided with a mounting hole 2011 for the headband 30 to pass through) and a first space 202 that is connected at least at two ends on a surface of the base. The first space 202 is equivalent to a space surrounded by an annular body, and the lamp body 10 can be inserted into the first space 202 along the two end directions of the first space 202. In order to enable the lamp body 10 to be quickly assembled and disassembled in the first space 202 of the bracket 20, in the present embodiment, the shell 1 of the lamp body 10 is improved, that is, the shell 1 of the lamp body includes a first shell portion 11 located at the insertion end and a second shell portion 12 subsequent to the first shell portion 11, wherein the outer diameter of the first shell portion 11 is smaller than the outer diameter of the second shell portion 12, and the first shell portion 11 is clearance-fitted with the first space 202, and the second shell portion 12 can be rotatably connected with the bracket 20 after interference fit with the first space 202, that is, at this time, the interference fit between the second shell portion 12 and the first space 202 cannot be too tight, and there is damping between the two, so that the second shell portion 12 can rotate relative to the first space 202. In this way, when plugging and connecting, the first shell part 11 serving as the insertion end first enters the first space 202. Since the two are clearance-matched, they can play a guiding role during insertion, so that the insertion end of the lamp body 10 can be quickly inserted into the first space 202, and the subsequent second shell part 12 can also be quickly guided into the first space 202. With the help of the interference fit between the second shell part 12 and the first space 202, after the lamp body 10 is rotated into place, it can be positioned at the desired angle relative to the bracket 20, that is, the lamp body 10 is at the angle required for lighting. In addition, such a structure prevents the risk of the lamp body 10 accidentally detaching from the bracket 20 after installation. At the same time, even if the user performs a blind insertion, the lamp body 10 can be guided to the correct position, thereby reducing the chance of misoperation.

[0027] In order to prevent the lamp body 10 from being excessively inserted into the first space 202 relative to the bracket 20 during the above-mentioned mating, in this embodiment, a limit portion 13 is further provided on the housing 1 of the lamp body. When the second housing portion 12 is inserted into the working position in the first space 202, the limit portion 13 abuts against an end surface of the first space 202, and the end surface corresponds to the insertion end of the second housing portion 12. Figure 5It can be known that the housing 1 of the lamp body in this embodiment includes a barrel head shell 1a at the head, a barrel body shell 1b in the middle and a barrel tail shell 1c at the tail, wherein the barrel tail shell 1c becomes the above-mentioned first shell part 11, which is threadedly connected with the first barrel body shell 11b described below; the barrel body shell 1b is composed of a first barrel body shell 11b and a second barrel body shell 12b threadedly connected to each other, and the first barrel body shell 11b and the second barrel body shell 12b together become the above-mentioned second shell part 12; the light source part 2 is installed in the barrel head shell 1a, and the axis L1 of the light source part 2 is perpendicular to the axis L2 of the shell. In this embodiment, in order to have lighting functions at different angles, an auxiliary light source 3 is also installed in the barrel head shell 1a, and light is emitted through a light-transmitting cover 4 constrained at the end of the barrel head shell 1a. The above-mentioned limiting portion 13 is located on the barrel head shell 1a and is adjacent to the second barrel body shell 12b. It is preferably designed as a convex ring, and in the figure, there are two convex rings, which are distributed at intervals along the axial direction of the outer shell, and a neck 14 is formed between the two convex rings. The mounting portion of a pen clip 40 is designed as a clamping ring 401 with a bayonet, and the clamping ring 401 is clamped on the neck 14 through the bayonet, so that after the main body 10 of the lamp is detached from the bracket 20, it can also be clamped in the user's pocket through the pen clip 40 for easy use or carrying.

[0028] In order to provide a better guiding effect during the use, the bracket 20 at at least one end of the first space 202 is provided with a second space 203 connected to the first space 202. Figure 2 and Figure 3 It can be seen that the second space 203 is preferably provided at both ends of the left and right sides of the first space 202, and the inner diameter of the second space 203 is larger than the inner diameter of the first space 202 to form a guide cavity. And in order to facilitate blind insertion, the second space 203 is smoothly connected to the first space 202 (specifically, it can be formed by chamfering). And in order to allow the inner diameters of the first space 202 and the second space 203 to change slightly during the insertion of the lamp body 10, the side wall of the first space 202 is provided with a channel that penetrates its thickness and extends axially to the second space 203, so that an opening 204 is formed on the side walls of the first space and the second space, that is, as shown in FIG. Figure 2 and Figure 3It can be seen that after the opening 204 is formed on the side wall of the first space and the second space, the cross section of the side wall of the first space and the second space is C-shaped, so that during the insertion process of the lamp body 10, the opening size of the opening 204 will change, so that the inner diameter of the first space 202 and / or the second space 203 can be enlarged, which is ultimately conducive to the rapid insertion of the lamp body 10, and after the lamp body 10 is inserted into place, the existence of the opening can improve the clamping force of the first space 202 on the lamp body 10. Further, the inner diameter of the second space 203 is larger than the outer diameter of the second housing portion 12, and the inner diameter of the second space 203 is larger than the outer diameter of the second housing portion 11 by Y, and Y is preferably greater than or equal to 0.5mm, and the most preferred value is 0.5mm. At the same time, the outer diameter of the second housing portion 12 is larger than the inner diameter of the first space 202 by X, and the value range of X is 0≤X≤1.5mm, preferably 0.5mm≤X≤1.5mm, and the most preferred value is 0.5mm.

[0029] In this way, no matter whether the lamp body 10 is inserted into the first space 202 from right to left or from left to right (as shown by the arrow on the bracket, with IN (entry) / OUT (extraction) marked as a prompt), the second space 203 guides the first shell part 11 and the second shell part 12 in turn for the first time, and then the first space 202 guides the first shell part 11 for the second time, so that the second shell part 12 can be quickly and smoothly inserted into the first space 202, and it is easy to rotate after installation without the risk of accidental detachment. Even if it is blindly inserted, the plug-in connection between the lamp body 10 and the bracket 20 can be smoothly achieved.

[0030] Although the preferred embodiments of the utility model are described in detail above, it should be clearly understood that for those skilled in the art, the utility model can also have various modifications and changes, such as only one second space 203 is provided. Alternatively, the limit portion 13 can be designed in the form of a convex point, and a stop portion that abuts against the convex point can be designed on the inner wall of the first space. Alternatively, the second housing portion 12 is not adjacent to the first housing portion 11, and a connecting portion having an outer diameter not greater than the outer diameter of the second housing portion is provided between the two. That is, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
