Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a magnet structure and a lamp. Background Art
[0002] In order to quickly position the product on the substrate of an external installation, a magnet is usually installed on the product's mounting surface. For example, in the case of a lighting fixture, the magnet is often located on the mounting surface of the fixture's housing. Specifically, when the housing is the main housing of the lamp, the magnet is located on the mounting surface of the main housing. When the housing includes a main housing and a secondary housing (such as a bracket) that rotates relative to the main housing, the magnet is installed on the mounting surface of the secondary housing (also known as the bracket's frame) to enable the lamp to magnetically adhere to the surface of the substrate (iron), freeing the user's hands to work.
[0003] However, existing magnet mounting structures often feature a flat mounting surface designed to accommodate the magnet's attachment to a corresponding surface on a substrate. However, in actual installation environments, the substrate's corresponding surface may not necessarily have a corresponding flat surface for attachment. For example, if the substrate is a rod or tube, the magnet's attachment to the mounting surface may cause the product to wobble, preventing it from being securely positioned. Therefore, further improvements are needed. Utility Model Content
[0004] The first technical problem to be solved by the present invention is to provide a magnet installation structure that can firmly position the product in view of the current status of the existing technology.
[0005] The second technical problem to be solved by the present invention is to provide a lamp with the above-mentioned magnet mounting structure that can be firmly positioned on a base in view of the current status of the existing technology.
[0006] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a magnet mounting structure, including a magnet arranged on the mounting surface of the product, characterized in that: an arc-shaped recess is provided on the mounting surface, the arc-shaped recess is used to match the tubular surface of the base, and the magnet is used to magnetically adsorb with the surface of the base.
[0007] Preferably, the product includes a bracket, and the mounting surface is formed by the bottom surface of the bracket body and the outer end surface of the pressure plate detachably connected to the bracket body. A groove is provided on the bottom surface of the bracket body, and the pressure plate is located in the mouth of the groove, and the magnet is mounted on the pressure plate.
[0008] It is further preferred that the arc-shaped recess is formed on the bottom surface of the frame and the outer end surface of the pressure plate, and a damping member is provided at least at the arc-shaped recess of the pressure plate, and the damping surface of the damping member is not lower than the surface of the arc-shaped recess.
[0009] In order to enhance the magnetic attraction, a further improvement is that the pressure plate is also detachably connected to an iron plate located in the groove, the upper part of the magnet is clamped between the iron plate and the pressure plate, and the lower part of the magnet is inserted into the through hole in the middle area of the pressure plate.
[0010] A further improvement is that the damping member is a plurality of damping frames respectively constrained at the corresponding edges of the iron plate, and each damping frame extends a damping foot toward the pressure plate, and the extended end of the damping foot can be inserted into the through hole on the pressure plate, and the end face of the extended end of the damping foot forms the damping surface.
[0011] In order to facilitate magnetic conduction and assembly, the edge of the iron plate is bent toward the pressure plate to form a folded edge that can be seated in the limiting groove on the corresponding damping frame. The folded edge can be inserted into the socket of the pressure plate to achieve a plug-in connection between the pressure plate and the iron plate.
[0012] Preferably, the insertion hole and the through hole are connected to facilitate processing and assembly.
[0013] In the above solutions, a further improvement is that there are two arc-shaped recesses, which are distributed perpendicular to each other, so as to facilitate more flexible installation of the product on the base of the object to be installed.
[0014] Preferably, the surface of the magnet does not protrude from the surface of the arc-shaped recess, so as to ensure reliable fit between the arc-shaped recess and the surface of the substrate.
[0015] The technical solution adopted by the present invention to solve the second technical problem is: a lamp, including a mounting surface and a magnet mounting structure, characterized in that the magnet mounting structure adopts the above-mentioned magnet mounting structure.
[0016] Compared with the prior art, since an arc-shaped recess is added to the mounting surface of the utility model, the arc-shaped recess can be used to cooperate with the tubular surface of the base, so that the magnet and the base can play a reliable limiting role when adsorbed, thereby effectively preventing the product from swinging after magnetic attraction. At the same time, after adding a damping member in the arc-shaped recess, it can further improve the stability of the product after placement while playing an anti-slip role. And with the help of the magnetic conductivity of the iron plate, the magnet can be reduced at the same suction force, saving costs. In particular, after such a magnet mounting structure is applied to the lamp, it can be stably adsorbed on the plane of the base, and can also be stably placed on the tubular or rod-shaped surface of the base, making such lamps more widely applicable and more flexible to use.

For example, "up" and "down" 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] The magnet mounting structure of this embodiment can be applied to various products, such as lamps or decorative items that require magnetic positioning. For ease of description and a clear understanding of the structure of the present invention, the following embodiments illustrate the magnet mounting structure on a lamp. Since lamps can take many different forms, this example uses a work lamp with a bracket rotatably connected to the main housing.
[0026] like Figure 1As shown, the lamp includes a housing with a mounting surface, a lighting assembly (not shown) located on the housing, and a magnet mounting structure. The housing further includes a main housing 10 and a sub-housing, wherein the sub-housing is a bracket 20. The bracket 202 is connected to the main housing 10 of the work lamp by a rotational connection. The main housing 10 of the work lamp, the lighting assembly, and the rotational connection structure between the main housing 10 and the bracket 20 can all adopt existing technologies. In this embodiment, the mounting surface is located on the bracket 20. The main improvement lies in the magnet mounting structure. The magnet mounting structure includes a magnet 1 disposed on the mounting surface of the bracket 20. The mounting surface is provided with an arc-shaped recess A. The arc-shaped recess A is used to match the tubular surface (here, the tubular shape is not necessarily hollow, but refers to a columnar object with a cylindrical or conical surface) of the base of the external installation object. The magnet 1 is used to magnetically attract the tubular surface of the base. In this case, the magnet 1 can be used to magnetically attract the tubular surface of the base, or it can be magnetically attracted to other flat surfaces on the base.
[0027] In order to facilitate the installation of the magnet 1, the bracket 20 is designed as a split structure, that is, it includes a frame body 2 and a pressure plate 3, wherein a groove 21 is provided on the bottom surface of the frame body 2, and the pressure plate 3 is located in the mouth of the groove 21 and fixed to the frame body 2 by two bolts 4. At this time, the bottom surface of the groove 21 on the frame body 2 and the outer end surface of the pressure plate 3 together form a mounting surface. Figures 2 to 6 It can be seen that there are two arc-shaped concave portions A, which are distributed perpendicular to each other, that is, respectively according to Figure 1 The mounting surface extends in the directions indicated by arrows B and C on the bottom surface of the frame 2 and the outer end surface of the pressure plate 3, thereby making the installation of the lamp more flexible. When the magnet 1 is mounted on the pressure plate 3, it is best if the surface of the magnet 1 does not protrude from the surface of the arc-shaped recess A to further improve the stability of the positioning.
[0028] At the same time, in order to have a greater suction force under the same magnet 1, in this embodiment, the iron plate 5 located in the groove is also detachably connected to the pressure plate 3. The upper part of the magnet 1 is sandwiched between the iron plate 5 and the pressure plate 3, and the lower part of the magnet 1 is inserted into the through hole 31 in the middle area of the pressure plate 3. That is, at this time, the pressure plate 3, the magnet 1 and the iron plate 5 are combined into one body and placed together in the groove 21. In order to facilitate magnetic conduction and improve assembly efficiency, the edges of the iron plate 5 indicated by the arrow C are bent toward the pressure plate 3 to form folded edges 51. The folded edges 51 can be inserted into the corresponding sockets on the pressure plate 3, so that the pressure plate 3 and the iron plate 5 are plugged and connected.
[0029] In order to increase the damping after contact with the substrate, a damping member is also provided on the above-mentioned mounting surface. In this embodiment, in order to facilitate assembly and to increase the damping force during limiting, the damping member is located in the arc-shaped recess of the pressure plate 3, and the damping surface of the damping member is not lower than the surface of the arc-shaped recess A, ensuring that the damping surface of the damping member can reliably contact the surface of the substrate. In this case, the damping member can be a sheet-like body directly attached to the arc-shaped recess of the pressure plate 3, but the following structure is preferably adopted: the damping member is composed of two damping frames 6 respectively constrained at the edge of the folded edge of the iron plate 5, and each damping frame 6 extends a damping leg 61 toward the pressure plate 3. The extended end of the damping leg 61 can be inserted into the through-hole on the pressure plate 3 and is flush with the outer end surface of the pressure plate 3. The end surface of the extended end of the damping leg forms the damping surface, which can directly contact the substrate. In order to facilitate processing, the insertion hole and the through-hole are connected. At the same time, in order to be combined with the above-mentioned damping frame 6, a limiting groove 62 is provided on the damping frame 6 at the position corresponding to the folded edge of the iron plate 5 for the folded edge 51 to be inserted.
[0030] Since two arc-shaped recesses A are provided, those skilled in the art will understand that the number of damping legs 61 on each damping frame 6 should also be increased accordingly to match the number of arc-shaped recesses A. In the figure, there are four damping legs 61 on each damping frame 6, which are grouped in pairs. There are two limiting grooves 62 on each damping frame 6, and each limiting groove 62 is located between two damping legs 61 in a group of damping legs. Accordingly, each iron plate 5 has two folded edges 51 on the edge indicated by the arrow C. The two damping legs 61 and the corresponding insertion holes and through-holes of one folded edge 51 are connected to form an L-shaped long hole 32. There are four such L-shaped long holes 32 in total, distributed along the circumference of the pressure plate 3.
[0031] During assembly, the damping frame 6 and the iron plate 5 can be combined together first, that is, each folded edge 51 can be inserted into the corresponding limit groove 62 of the damping frame 6, so that the two damping frames 6 are constrained at the corresponding edges of the iron plate 5, and then the magnet 1 is placed on the iron plate 5 (or the magnet 1 can be placed on the iron plate 5 first, and then assembled with the damping frame 6), and then the damping foot 61 on the damping frame 6 and the folded edge 51 on the iron plate 5 are simultaneously inserted into the corresponding L-shaped long hole 32. At this time, the pressure plate 3, the magnet 1, the iron plate 5 and the damping frame 6 have been assembled into an assembly. Finally, the assembly is placed in the groove 21 of the frame body 2, and then the pressure plate 3 and the frame body 2 are fixed into one with two bolts 4.
[0032] In order to allow the above components to be quickly inserted into place, positioning ribs 22 are provided in the grooves 21 of the frame body 2, and positioning grooves 63 are provided on the damping frame 6 for the insertion of the positioning ribs 22. At the same time, positioning pieces 52 extend from the two edges indicated by the arrow B of the iron plate 5, and corresponding accommodating grooves 33 are provided on the back side of the pressing plate 3 for the insertion of the positioning pieces 52. In addition, in order to prevent the folded edge 51 on the iron plate 5 from being excessively inserted into the pressing plate 3, blocking pieces 53 are bent and extended from the edges on both sides of the positioning piece 52 of the iron plate 5 toward the pressing plate 3. When the folded edge 51 is inserted into the pressing plate 3 and is in place, the blocking piece 53 abuts against the inner end surface of the pressing plate 3. In this way, assembly is convenient and quick, and the assembled components are also more solid and less likely to fall apart.
[0033] Of course, the protection scope of the present invention is not limited to the above-mentioned embodiments. For example, the above-mentioned arc-shaped recess can be provided only on the bottom surfaces on both sides of the groove of the frame 2, and in this case, the outer end surface of the pressure plate 3 is not higher than the surface of the arc-shaped recess. Or the arc-shaped recess can be provided only on the outer end surface of the pressure plate 3, and similarly, the bottom surfaces on both sides of the groove of the frame 2 are not higher than the surface of the arc-shaped recess. Or the damping member is provided as a sheet-like body, adhered to the location of the arc-shaped recess on the bottom surface of the frame 2; or the damping member is located on the mounting surface around the magnet 1, on the magnet 1, or at the junction of the pressure plate 3 and the frame 2. The damping member can also be designed into other shapes, such as a circle, etc., as needed. The damping frame can also be designed into four, etc.
