Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a die-cast hinge for lamps. Background Art

[0002] With the advancement of technology, the application of LED lights is becoming increasingly widespread. LED lights can output high-intensity light at regular intervals and provide customized light spectra tailored to plant types and different growth stages, resulting in higher yields, better quality, and shorter flowering and fruiting cycles. The main physical forms of plant lights include "octopus" lights, ceiling lights, and tube lights. Octopus-shaped plant lights, with a length and width exceeding 1 meter, are favored for their large illumination area, uniform illumination, and high light utilization, making them the mainstream of plant lights. However, their excessive length and width make them inconvenient to transport and carry, so they need to be folded before packaging and unfolded for use. The hinge is used for rotation and folding.

[0003] The hallmark of a hinge is its ability to rotate. One end of the hinge is fixed to object A (such as a door), and the other end is fixed to object B (such as a door frame). By rotating the hinge, object A can rotate around object B. Hinges are frequently used in daily life, especially for larger doors like freezer and truck doors, which all rely on hinges for rotation. Depending on the size, weight, and location of the rotating objects, hinges have varying requirements for strength, surface treatment, size, and price. Hinges are available in a variety of materials and finishes, including die-cast zinc, die-cast aluminum, and stainless steel.

[0004] Although the existing hinges can also meet the effect of folding the connecting parts, their overall strength is poor and they are easily damaged and deformed. Therefore, a new type of hinge is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a die-cast hinge for a lamp, so as to solve the technical problems of poor strength and easy deformation of the existing hinge.

The inner side of the inner hinge is provided with a first protrusion and a second protrusion, and the inner side of the outer hinge is provided with a first cavity and a second cavity. The center hole of the first protrusion is concentric with the center hole of the first cavity and is fixed by a screw. The center hole of the second protrusion is concentric with the center hole of the second cavity and is fixed by a stepped screw.

[0007] Preferably, a connecting block connected to the connecting piece is provided on the outer side of the inner hinge and the outer side of the outer hinge, and a plurality of screw holes are provided on the connecting block.

[0008] Preferably, the outer side of the first protrusion is an arc-shaped structure, and the second protrusion and the second cavity are columnar structures.

[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, the utility model is a die-cast hinge for a lamp, comprising an inner hinge 1, an outer hinge 2, a screw 3 and a step screw 4. The inner side of the inner hinge 1 is provided with a first protrusion 11 and a second protrusion 12, and the inner side of the outer hinge 2 is provided with a first cavity 21 and a second cavity 22. The center hole of the first protrusion 11 is concentric with the center hole of the first cavity 21 and is fixed by the screw 3. The center hole of the second protrusion 12 is concentric with the center hole of the second cavity 22 and is fixed by the step screw 4.

[0022] The utility model is a die-cast hinge for a lamp, which mainly includes an inner hinge 1, an outer hinge 2, a screw 3 and a step screw 4, wherein the inner side of the inner hinge 1 is provided with a first protrusion 11 and a second protrusion 12, and the inner side of the outer hinge 2 is provided with a first concave cavity 21 and a second concave cavity 22. The inner hinge 1 is connected to the outer hinge 2 by the screw 3 and the step screw 4 to ensure the stability of the hinge.

[0023] In a preferred embodiment, referring to Figure 1-4 The outer sides of the inner hinge 1 and the outer hinge 2 of the die-cast hinge for the lamp are provided with a connecting block 6 connected to the connecting piece 5, and a plurality of screw holes 61 are provided on the connecting block 6. The outer side of the first protrusion 11 is an arc-shaped structure, and the second protrusion 12 and the second cavity 22 are columnar structures. The aperture of the center hole of the second protrusion 12 is larger than the aperture of the center hole of the second cavity 22. Both the inner hinge 1 and the outer hinge 2 are made of zinc alloy material and are processed by die-casting technology to ensure simple and convenient processing. The length of the rear end of the step screw 4 is higher than the depth of the center hole of the second protrusion 12. The center hole of the second protrusion 12 is a through hole, and the center hole of the second cavity 22 is a screw hole.

[0024] The center hole of the second concave cavity 22 of the outer hinge is a machine thread that fits the front end of the step screw 4. The center hole of the second protrusion 12 is a through hole that fits the rear end of the step screw 4. The center holes of the two are concentric. When in use, the step screw 4 is first inserted into the center hole of the second protrusion 12, then inserted into the center hole of the second concave cavity 22, and tightened to firmly connect the step screw 4 to the outer hinge 2. At the same time, because the step of the step screw 4 is higher than the plane of the center hole of the second protrusion 12, the inner hinge 1 is prevented from being locked and can instead rotate freely around the step screw as the central axis. In addition, the connecting block 6 is the screw hole for the external connection, which is used to connect the hinge to the external connector 5. The inner hinge 1 and outer hinge 2 kit is inserted into the cavity of the hardware connector of the lamp and fixed to the connector with screws through the screw holes 61 on the hinge. When the inner hinge and the outer hinge rotate to 180 degrees to each other, the lamp body is in the unfolded state. At this time, under the influence of gravity, the inner hinge 1 and the outer hinge 2 are subjected to an inward push force, supporting each other. Finally, the lamp is lifted up with ropes at the four corners.

[0025] Furthermore, the screw 3 on the hinge serves as a reinforcing insurance. The center hole in the first protrusion 11 is a through hole, and the center hole in the first cavity 21 is a screw hole. When the inner hinge 1 and the outer hinge 2 are rotated to 180° relative to each other, the lamp body is in the unfolded state, which is also the state of use by the customer. Since the center hole of the first protrusion 11 is concentric with the center hole of the first cavity 21, at this time, the screw 3 is screwed from the center hole of the first protrusion 11 into the center hole of the first cavity 21, thereby serving as a reinforcing insurance.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
