Description

Technical Field

[0001] The invention relates to the technical field of a clip and a lamp thereof. Background Art

[0002] A clip is a common tool for clamping things, and can also be used to assist products (such as lamps, documents) to be positioned on the desired clamped object. Currently, the clip usually includes a first clamping body and a second clamping body hinged by a pin shaft, and an elastic member (commonly a torsion spring) sleeved on the pin shaft. The first clamping body has a first clamping portion located on one side of the pin shaft and a first operating portion located on the other side of the pin shaft. Similarly, the second clamping body is formed with a second clamping portion corresponding to the first clamping portion and a second operating portion corresponding to the first operating portion. The elastic member can make the above-mentioned first clamping portion and the second clamping portion always have a tendency to be relatively close to each other, so as to achieve the purpose of clamping the clip on the clamped object.

[0003] However, looking at the existing clamps, when they carry products, they cannot guarantee effective clamping in multiple scenarios. For example, when a lamp with a clamp is clamped on a car hood, curved panels, special-shaped objects, etc., its clamping force cannot be guaranteed, resulting in the product either being unstable in positioning; or the clamping force is too large, which may damage the surface of the clamped object. In severe cases, the clamped object may even be damaged.

[0004] Therefore, further improvement is needed for the existing clip and lamp thereof. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a clamp which can adapt itself to the surface of the clamped object and achieve a snug clamping effect, with respect to the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a lamp with the above-mentioned clip in view of the prior art, so that the lamp can be positioned on the clamped object by the clip being able to adapt to the surface of the clamped object to achieve a snug clamping effect.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a clamp, including a first clamping body and a second clamping body hingedly connected by a pin shaft and an elastic member acting on the first and second clamping bodies, the first clamping body including a first clamping part located on one side of the pin shaft and a first operating part located on the other side of the pin shaft, the second clamping body is formed with a second clamping part corresponding to the first clamping part and a second operating part corresponding to the first operating part, the elastic member can make the above-mentioned first clamping part and the second clamping part always have a tendency to be relatively close, characterized in that: it also includes a movable clamping plate, the middle part of the movable clamping plate is hinged on one of the first clamping part and the second clamping part, and the movable clamping plate is designed with a concave clamping surface that cooperates with the other clamping part of the first clamping part and the second clamping part.

[0008] The structure of the above-mentioned movable clamp can have various forms, but preferably, the movable clamp includes a first force arm extending toward the pin shaft side in the natural state of the clamp and a second force arm extending toward the end side of the other clamping part, and the concave clamping surface is located on the first and second force arms to form a seesaw structure, allowing its force arms to better clamp the clamped object.

[0009] In order to allow the movable clamping plate to have a larger rotation clamping degree during the rotation process, one of the clamping parts is provided with a receiving cavity capable of accommodating the first force arm. With the receiving cavity, thicker clamped objects can be clamped under the same appearance, so as to expand the application scenarios.

[0010] In order to prevent the first force arm from being over-inserted into the accommodating cavity, a rib extends laterally from the side of the first force arm. When the first force arm is located in the accommodating cavity, the rib can resist the side of one of the clamping parts, and the surface of the rib facing the other clamping part becomes a part of the concave clamping surface. By utilizing the rib, the pressing surface can also be increased, making the clamping more stable.

[0011] In order to keep the distance between the first and second force arms as long as possible, the angle formed between the first force arm and the second force arm is an obtuse angle to increase the reliability of clamping.

[0012] Similarly, in order to make the first force arm as long as possible, the middle part of the movable splint is hinged to the end of one of the clamping parts away from the pin shaft through a rotating shaft, and when the first force arm is rotated and detached from the accommodating cavity, the edge of the end can abut against the limiting part on the second force arm to prevent excessive rotation of the movable splint.

[0013] In order to improve the flexibility of the movable clamping plate, the middle part of the movable clamping plate is designed as a hollow structure, and the concave clamping surface is designed at the edge of the movable clamping plate. In this way, interference with the clamped object can be avoided, ensuring that the seesaw effect is not invalidated.

[0014] In order to further improve the clamping effect, the concave clamping surface of the movable clamping plate is designed with a plurality of first concave and convex surfaces distributed in sequence and at intervals.

[0015] In order to match with the above-mentioned concave clamping surface, the surface of the other clamping portion corresponding to the concave clamping surface can be designed as a plane; or can be designed as a second concave-convex surface.

[0016] Preferably, the multiple first recesses are designed to be multiple arc-shaped recesses or multiple trapezoidal recesses or multiple tooth-shaped recesses, or are formed by a combination of at least two of the arc-shaped recesses, trapezoidal recesses, and tooth-shaped recesses; the second concave-convex surface has various forms, and preferably, it can be designed as a tooth-shaped surface; or an arc-shaped concave-convex surface formed by arc-shaped recesses and arc-shaped convex portions distributed in sequence; or a trapezoidal concave-convex surface formed by trapezoidal recesses and trapezoidal convex portions distributed in sequence; or it is formed by a combination of at least two of the tooth-shaped surface, arc-shaped recesses, arc-shaped convex portions, trapezoidal recesses, and trapezoidal convex portions.

[0017] In order to extend the service life of the clamp, it is better that a first wear-resistant pad is provided on the concave clamping surface, and a second wear-resistant pad corresponding to the first wear-resistant pad is provided on the other clamping part. The first and second wear-resistant pads can also be used to avoid damaging the surface of the clamped object.

[0018] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a lamp, including a clip and a lighting assembly installed on the clip, characterized in that: the clip adopts the above-mentioned clip, the lighting assembly is rotatably installed on a second clamp body through a connecting piece, and the movable clamp plate is also installed on the second clamp body.

[0019] Compared with the prior art, since one of the clamping bodies of the present invention is provided with a relatively rotatable movable clamping plate, and the clamping surface of the movable clamping plate is designed as a concave structure, when encountering different clamped objects, the movable clamping plate will automatically rotate and adjust according to the shape of the surface of the clamped object during the clamping process, and under the mutual clamping of the concave structure of its clamping surface and the other clamping body, the concave clamping surface is as close to the surface of the clamped object as possible, and the purpose of at least three-point positioning and effective clamping can be achieved, and at the same time, the concave clamping surface and the clamped object can have appropriate friction, and the surface of the clamped object will not be damaged. When it carries products, especially lamps, this effect is more obvious, so it is worth promoting and applying. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The clip in this embodiment can be used alone to clamp the mouth of a bag or to clamp multiple parts, etc. It can also be used to carry products, such as lamps, to clamp and position the products in a desired position. For ease of understanding and description, in this embodiment, the clip is applied to lamps. Existing lamps have various structures, such as table lamps, work lamps, etc. The following will take the work lamp as an example for description.

[0031] like Figures 1 to 8As shown in the figure, it is a preferred embodiment of the present invention. The lamp is a work lamp, which includes a clip 10 and a lighting assembly 20 mounted on the clip, wherein the clip 10 includes a first clamping body 1 and a second clamping body 2 and an elastic member which are hinged by a pin a, the first clamping body 1 includes a first clamping portion 11 located on one side of the pin a and a first operating portion 12 located on the other side of the pin a, and the second clamping body 2 is formed with a second clamping portion 21 corresponding to the first clamping portion 11 and a second operating portion 22 corresponding to the first operating portion 12. The elastic member adopts a torsion spring b, which is sleeved on the pin a. In the figure, there are two pins a and they are arranged coaxially. The torsion spring b can be one and sleeved on one of the pins a, or two can be designed and sleeved on their respective pins a. The two ends of the torsion spring b act on the first operating portion 12 and the second operating portion 22 respectively, so that the first clamping portion 11 and the second clamping portion 21 always have a tendency to be relatively close to each other, and these can adopt the existing technology. In this embodiment, a movable clamping plate 3 is mainly provided, the middle part of which is hinged on one of the first clamping part 11 and the second clamping part 21, and the movable clamping plate 3 is designed with a concave clamping surface 31 that matches the other clamping part of the first clamping part 11 and the second clamping part 21. That is, the movable plate 3 can be hinged on the first clamping part 11 of the first clamping body 1, or can be hinged on the second clamping part 21 of the second clamping body 2. In this embodiment, since the lighting assembly 20 is installed on the second clamping body 2, it is preferred that the movable clamping plate 3 is also hinged on the second clamping part 21 of the second clamping body 2, and the hinge structure between the movable clamping plate 3 and the second clamping part 21 can adopt various hinge structures in the prior art. In this embodiment, the middle part of the movable clamping plate 3 is hinged on the second clamping part 21 through the rotating shaft c, and since the middle part of the movable clamping plate 3 described below is designed as a hollow structure, the rotating shaft c in the figure is designed with two coaxially distributed shafts.

[0032] The clamping surface on the above-mentioned movable clamping plate 3 is designed as a concave structure, that is, the clamping surface of the movable clamping plate 3 facing the first clamping part 11 is not a plane, nor a convex surface facing the first clamping part 11, but a concave design. Specifically, the movable clamping plate 3 includes a first force arm 32 extending toward the pin a side in the natural state of the clamp and a second force arm 33 extending toward the end side of another clamping part (i.e., the first clamping part 11 in the figure). After the first force arm 32 and the second force arm 33 are combined, the movable clamping plate forms a herringbone structure. Of course, the first force arm and the second force arm can also be combined to form other shapes such as C-shaped, and the above-mentioned concave clamping surface 31 is located on the lower surface of the first and second force arms. In addition, in order to make the first and second force arms as far apart as possible to increase the length of the two force arms, the middle part of the movable clamping plate 3 is hinged to the end of the second clamping part 21 away from the pin a through the above-mentioned rotating shaft c, and the angle formed between the first force arm 32 and the second force arm 33 is an obtuse angle. In this way, the moment of the movable clamping plate 3 can be increased to ensure the firmness and stability of the clamping.

[0033] At the same time, in order to maximize the rotation angle of the movable clamping plate 3, in this embodiment, it is further optimized that the second clamping portion 21 is further provided with an accommodating cavity 211 capable of accommodating the first force arm 32. Figure 3 and Figure 5 In order to prevent the first lever arm 32 from excessively entering the accommodating cavity 211, a retaining edge 321 is extended laterally on the side of the first lever arm 32 (see Figure 3 and Figure 4 ), when the first force arm 32 is located in the accommodating cavity 211, the retaining edge 321 can abut against the side of the second clamping portion 21, and the surface of the retaining edge 321 facing the first clamping portion 11 becomes a part of the concave clamping surface to widen the size of the clamping surface. At the same time, in order to prevent the first force arm 32 from rotating excessively when it is separated from the accommodating cavity 211 after rotation, the edge 212 of the end of the second clamping portion 21 can abut against the limiting portion 331 on the second force arm 33, see Figure 2 and Figure 3 As can be seen from the figure, the limiting portion 331 on the second force arm 33 can be connected with the above-mentioned retaining edge 321.

[0034] In order to allow the movable splint 3 to rotate flexibly and give full play to its seesaw function, the middle part of the movable splint 3 is designed to be a hollow structure, that is, the middle part is hollowed out (see Figure 4 and Figure 5 ), at this time, the concave clamping surface 31 is designed at the edge of the lower surface of the movable clamping plate 3, Figure 6 and Figure 7 In the embodiment, the concave clamping surface 31 is located at the edges on both sides of the lower surface of the movable clamping plate and the edges corresponding to the ends adjacent to the second clamping portion.

[0035] When in use, the concave clamping surface 31 of the movable clamping plate 3 can be used to cooperate with the first clamping portion 11 to effectively clamp the clamped object, and the use of this rotatable adaptive movable clamping plate 3 can simulate the grasping action of a human hand to achieve the purpose of effective clamping. In order to match the different surfaces of the clamped object, in this embodiment, the concave clamping surface 31 is further optimized, that is, the concave clamping surface 31 of the movable clamping plate 3 is also designed with a plurality of first recesses distributed in sequence, and the first recesses can be tooth-shaped recesses (pointed teeth); or arc-shaped recesses, so as to facilitate clamping of the clamped object such as a round tube; or trapezoidal recesses; or at least two combinations of tooth-shaped recesses, arc-shaped recesses, and trapezoidal recesses. Figure 2 In the embodiment, the first concave portion includes a first arc-shaped concave portion 311, a deeper first trapezoidal concave portion 312 and a shallower second trapezoidal concave portion 313 which are sequentially distributed from the front end to the pin a side. The surface of the first clamping portion 11 corresponding to the concave clamping surface 31 can be designed as a plane, but in this embodiment, the surface of the first clamping portion 11 is also designed as a second concave-convex surface corresponding to the concave clamping surface 31. Figure 4 In the embodiment, the second concave-convex surface includes a second arc-shaped recess 111 corresponding to the first arc-shaped recess 311, a third trapezoidal recess 113 corresponding to the first trapezoidal recess 312, and a second trapezoidal convex portion 114 corresponding to the second trapezoidal recess 313, and a second tooth-shaped portion 112 is formed between the second arc-shaped recess 111 and the third trapezoidal recess 113. During the clamping process, the movable clamp 3 can be based on the shape of the clamped object. When one of the force arms is forced to rise, the other force arm will rotate downward (i.e. press down), so that the movable clamp 3 will automatically fit the clamped object based on the working principle of a seesaw. In addition, since the middle of the concave pressing surface of the movable clamp 3 is a deeper first trapezoidal recess 312, it can be ensured that there are eventually two highest points on the concave clamping surface of the entire movable clamp 3 that contact the clamped object. In other words, the clamped object has at least two force points on this concave clamping surface. Due to the general principle of the clamp, there will also be at least one point on the first clamping portion 11 that is forced on the clamped object, so that the entire clamp is formed with at least three stable force points to form a firm clamping shape.

[0036] In order to prevent the clamp 10 from being worn too quickly and to protect the surface of the clamped object, a first wear-resistant pad 4a is provided on the concave clamping surface 31, and a second wear-resistant pad 4b corresponding to the first wear-resistant pad 4a is provided on the first clamping portion 11. Since the concave clamping surface 31 and the surface of the first clamping portion are designed as concave-convex surfaces, the first wear-resistant pad 4a and the second wear-resistant pad 4b are also designed to be in accordance with the corresponding concave-convex surfaces. At the same time, a third wear-resistant pad 4c is fixed on the surface of the second clamping body 2 adjacent to the first clamping portion 11. By replacing the corresponding wear-resistant pad, the service life of the clamp 10 can be extended and the surface of the clamped object can be ensured not to be damaged by the clamping.

[0037] The lighting assembly 20 in the above-mentioned lamp can adopt the structure in the prior art. In this embodiment, in order to have a better lighting effect, the lighting assembly 20 is rotatably mounted on the second clamping body 2 through the connecting member 30, and preferably, the connecting member 30 and the clamp 10 can be relatively rotatably connected around the first axis L1, and the lighting assembly 20 and the connecting member 30 can be relatively rotatably connected around the second axis L2, so that the lighting assembly 20 can be rotated in multiple directions to meet the lighting needs in different occasions.

[0038] The above-mentioned connecting member 30 can adopt various structures in the prior art. In the figure, the connecting member 30 includes a first rotating member 5 and a second rotating member 6, wherein the first rotating member 5 can be rotatably constrained on the second operating part 22 of the second clamp 2 around the first axis L1, and the second rotating member 6 can be rotatably constrained on the first rotating member 5 around the second axis L2, and is connected to the lighting assembly 20.

[0039] At the same time, in order to facilitate the heat dissipation of the lighting assembly 20, the present lamp is also designed to be thermoelectrically separated, that is, a battery cavity 23 for the battery 40 is provided on the second clamp 2, and the battery 40 is electrically connected to the lighting assembly 20 through a wire, and the wire can be passed through the cavity of the above-mentioned rotating member to achieve the purpose of supplying power to the light-emitting body 201 in the lighting assembly 20. A cover plate 7 is also added to the second clamp 2, and the cover plate 7 can cover the mouth of the battery cavity 23 to prevent the battery 40 from falling out of the battery cavity 23. Since the battery 40 is separated from the lighting assembly 20, the heat generated by the battery 40 and the heat generated by the light-emitting body 201 during use have little mutual influence, and are conducive to the heat dissipation of each other, so that the phenomenon of overheating of the lighting assembly can be avoided, and ultimately the safety of use can be improved and the service life of the lamp can be extended.
