Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lighting fixture and its installation structure. Background Technology

[0002] With the continuous development of the building decoration industry, recessed lighting fixtures are widely used in various indoor lighting scenarios due to their aesthetic appeal and practicality. Currently, most recessed lighting fixtures on the market use a spring-loaded installation method. A typical structure includes U-shaped brackets and torsion springs on both sides of the fixture. The U-shaped brackets are connected to the torsion springs and driven by the springs, providing a pre-tightening force to engage with the mounting base. While this installation method is simple in structure and low in cost, it presents several problems in practical use, causing considerable inconvenience for electricians. Specifically, this type of spring-loaded structure typically lacks necessary auxiliary installation functions. During installation, the free end of the spring is prone to colliding with the ceiling, causing scratches or damage to the ceiling surface and affecting the overall aesthetics of the decoration. Furthermore, the spring can easily pinch the electrician's hand during compression and release, creating a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a novel lamp mounting structure and a lamp containing the mounting structure.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a mounting structure for a lamp, used to mount the lamp onto a mounting base having mounting holes. The mounting structure includes a torsion spring connected to the housing of the lamp, and a protective sleeve. The protective sleeve includes a mounting base connected to a torsion bar of the torsion spring and an abutment portion disposed on the mounting base. The torsion bar and the abutment portion are respectively located on both sides of the mounting base. The abutment portion has an arched structure relative to the mounting base and has elastic deformation capability. The abutment portion is configured such that, under the action of an external force, the distance between its arched structure and the mounting base decreases to allow it to pass through the mounting hole, and is configured such that, after the external force is removed, the distance between the current arched structure and the mounting base increases.

[0006] The sleeve is designed to effectively prevent pinching and cutting of the mounting base (such as ceiling), and the abutment part on it facilitates installation and disassembly, while also serving as an auxiliary hook during the installation process.

[0007] In some embodiments, the abutment portion includes a first guide segment connected at one end to the mounting base and a second guide segment connected at the other end of the first guide segment, the connection point of the first guide segment and the second guide segment being located at the end of the mounting base away from the torsion spring, and forming the arched structure.

[0008] In some embodiments, the abutting portion further includes an extension extending from the end of the second guide segment, the free end of the extension extending beyond the end of the mounting base, and the free end being farther away from the end of the mounting base than the end of the second guide segment, so that the extension extending, under the action of an external force, drives the second guide segment and the first guide segment closer to the mounting base.

[0009] In some specific embodiments, the outer end face of the extension section is provided with damping grooves.

[0010] In some specific implementations, the width of the extension segment is greater than the width of the second guide segment.

[0011] In some specific implementations, the first guide segment, the second guide segment, and the extension segment are integrally formed.

[0012] In some implementations, the first guide segment and the second guide segment have a circular arc transition.

[0013] In some embodiments, the abutment portion is sheet-shaped, and the mounting base has a recess adapted to the abutment portion, with the starting end of the abutment portion located within the recess. The sheet-shaped abutment portion simultaneously possesses good elastic deformation capability and locking force.

[0014] In some embodiments, the mounting base and the abutment portion are integrally formed.

[0015] In some embodiments, the sheath is made of plastic.

[0016] In some embodiments, the mounting base is provided with a slot for engaging the torsion bar.

[0017] Furthermore, the mounting base is also provided with a limiting protrusion.

[0018] In some embodiments, at least two torsion springs are symmetrically arranged on the housing of the lamp, and the sheath corresponds one-to-one with the torsion springs.

[0019] Furthermore, after the lamp installation is completed, the abutment portion is located on the outside of the mounting base, and the distance between the arched structures of the two symmetrical abutment portions is greater than the diameter of the mounting hole on the mounting base.

[0020] This utility model also provides a lamp, the outer shell of which is provided with a mounting structure for fixing the lamp to a mounting base, the mounting structure being the mounting structure described above.

[0021] In some embodiments, the luminaire is an embedded luminaire.

[0022] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0023] This invention effectively prevents fingers from being pinched and cut on the mounting base by adding a protective sleeve to the torsion spring. The abutment part on the sleeve facilitates installation and disassembly, and also acts as an auxiliary hook during installation. The installation structure of this invention is convenient to operate, safe, and aesthetically pleasing. Attached Figure Description

[0040] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0041] Example 1

[0042] An installation structure, such as Figures 1 to 7As shown, it is used to mount the lamp 3 onto the mounting base 4 having mounting holes 41. The mounting structure includes a torsion spring 1 and a sheath 2. The torsion spring 1 is connected to the housing of the lamp 3 and is rotatable relative to the lamp 3, with a tendency to rotate towards the bottom of the lamp 3. The torsion spring 1 has a torsion spring body 11 and a torsion bar 12, and its connection with the lamp 3 is in accordance with the prior art. The sheath 2 includes a mounting base 21 and an abutment portion 22. The mounting base 21 is connected to the torsion bar 12 of the torsion spring 1, and the abutment portion 22 is disposed on the mounting base 21, with the torsion bar 12 and the abutment portion 22 located on opposite sides of the mounting base 21. The abutment portion 22 has an arched structure relative to the mounting base 21, and the abutment portion 22 has elastic deformation capability; the abutment portion 22 is configured such that under the action of external force, the distance between its arched structure and the mounting base 21 decreases to allow it to pass through the mounting hole 41, and is configured such that after the external force is removed, the distance between the current arched structure and the mounting base 21 increases. The design of the sleeve 2 effectively prevents pinching and cutting of the mounting base 4, and the abutment portion 22 on it facilitates installation and disassembly, while also serving as an auxiliary hook during installation.

[0043] Furthermore, the abutment portion 22 includes a first guide section 221 and a second guide section 222. One end of the first guide section 221 is connected to the mounting base 21, and the other end is connected to the second guide section 222. The connection point between the first guide section 221 and the second guide section 222 is located at the end of the mounting base 21 away from the torsion spring 1, forming the arched structure. When the mounting structure is in the installed state, as... Figure 1 As shown, the first guide segment 221 is inclined outward and extends upward, used to guide the first guide segment 221 towards the mounting base 21 when under force; the second guide segment 222 is inclined inward and extends upward, used to guide the second guide segment 222 towards the mounting base 21 when under force. The first guide segment 221 and the second guide segment 222 form an angle, thus creating an arched structure. Preferably, the angle between the first guide segment 221 and the second guide segment 222 is a right angle or an obtuse angle, which makes installation and disassembly more convenient. This is mainly reflected in:

[0044] During installation, only external force needs to be applied to deform the arched structure, specifically by reducing the angle between the first guide section 221 and the mounting base 21. Figure 1 Taking the installation perspective as an example, when installing to Figure 1 Before the position, the arched structure on the abutment part 22 on both sides is recessed inward until its distance is less than the diameter of the mounting hole 41, then the upper part of the sheath 2 can pass through the mounting hole 41.

[0045] After installation, the arched structure was restored to its original state. Figure 1The angle shown means that the distance between the arched structures on the two symmetrical sides is greater than the diameter of the mounting hole 41. The abutment part 22 can generate a horizontal outward force and a downward component force on the mounting hole 41, which improves the stability of the lamp in the mounting hole 41.

[0046] When disassembly is required, simply apply a downward force to the lamp fixture to cause the arched structure to retract inward again. This is much less effort than applying force to retract the non-deformable mounting base 21. The first guide section 221 and the second guide section 222 have a rounded transition, which can prevent the transition section from scratching the installation area during installation or disassembly.

[0047] The abutment portion 22 also includes an extension portion 223 extending from the end of the second guide segment 222. The free end of the extension portion 223 extends beyond the end of the mounting base 21, and this free end is farther away from the end of the mounting base 21 than the end of the second guide segment 222, so that the extension portion 223, under the action of external force, drives the second guide segment 222 and the first guide segment 221 closer to the mounting base 21. The extension portion 223 can reduce damage to the mounting base 4, and at the same time forms a guide slope with the second guide segment 222, which facilitates insertion into the mounting hole 41. Preferably, the outer end face of the extension portion 223 is provided with damping grooves 224. The width of the extension portion 223 is greater than the width of the second guide segment 222. In this embodiment, the abutment portion 22 is sheet-shaped, on which the first guide segment 221, the second guide segment 222, and the extension portion 223 are integrally formed.

[0048] The abutment portion 22 can be made of plastic and is preferably integrally formed with the mounting base 21. The mounting base 21 has a recess that matches the abutment portion 22, with the starting end of the abutment portion 22 located within the recess. The mounting base 21 has a slot 211 and a limiting protrusion 212 on the side where the torsion bar 12 is located. Multiple slots 211 are distributed on both sides of the mounting base 21. Preferably, the slots 211 are symmetrically distributed on the left and right sides of the mounting base 21, with one or more slots 211 on each side. In this embodiment, there are two slots 211 on each side, and the two arms of the torsion bar 12 are respectively engaged in the slots 211 on both sides of the mounting base 21. The limiting protrusion 212 is located at the end of the mounting base 21, and the connecting rod portion connecting the two arms of the torsion bar 12 abuts against the end of the limiting protrusion 212 to prevent relative sliding between the torsion spring 1 and the mounting base 21, thereby ensuring the stability of their connection.

[0049] Example 2

[0050] A lighting fixture 3 has a mounting structure for fixing the lighting fixture 33 to a mounting base 4. The mounting base 4 includes, but is not limited to, a ceiling, and has mounting holes 41.

[0051] The luminaire 33 is generally cylindrical, with a light outlet at its bottom. It houses a light-emitting device, controller, driver, etc., and specific details can be found in existing technology; this application does not impose specific limitations. There are at least two mounting structures, preferably evenly spaced around the outer perimeter of the luminaire 33. In this embodiment, two mounting structures are symmetrically arranged on both sides of the luminaire 3's housing. The mounting structure is the one described in Embodiment 1. Figure 1 As shown, after the installation of the lamp 3 is completed, the abutment part 22 is located on the outside of the mounting base 21, and the distance between the arched structures of the two symmetrical abutment parts 22 is greater than the diameter of the mounting hole 41 on the mounting base 4.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
