Description

Technical Field

[0001] This invention relates to a fixing mechanism, particularly a fixing mechanism that is not easily damaged by internal wiring and is easy to adjust, and a lamp using the fixing mechanism. Background Technology

[0002] Lighting fixtures are indispensable products for modern life. Generally speaking, they can be divided into fixed lighting fixtures that are fixed to the ceiling or suspended lighting fixtures that are suspended from the ceiling.

[0003] A suspended lighting fixture uses multiple suspension cables to connect a power source and a light-emitting element (such as a light bulb) from the ceiling, with the power source transmitting electricity to the light-emitting element via these suspension cables. The suspension cables are typically equipped with clamping mechanisms to adjust the distance between the suspended lighting fixture and the ceiling.

[0004] However, existing clamping mechanisms use steel balls to clamp the suspension wire inwards. The heavier the load, the tighter the steel balls clamp. If the suspension wire is an electric wire, this can damage the insulation layer and cause leakage. Furthermore, once the height of the existing suspended lighting device is determined, the suspension wire and clamping mechanism are usually fixed, making it impossible to readjust the height of the suspended lighting device according to the user's needs. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a fixing mechanism that is not easily damaged and is easy to adjust.

[0006] The fixing mechanism is used for passing through and clamping a wire, and includes a housing, a plurality of clamping members respectively disposed within the housing, and a biasing member. The housing has an inner wall surface and surrounds an accommodating space that communicates with the outside and extends axially along the housing, wherein the accommodating space has a large-diameter end and a small-diameter end. The clamping members are disposed within the accommodating space of the housing, each of the clamping members having an outer wall surface facing the inner wall surface of the housing, the outer wall surface being arc-shaped in cross-section along the axial direction and forming partial contact with the inner wall surface. The clamping members can be pushed towards the large-diameter end to separate the clamping members from each other, allowing the wire to move between the clamping members. The biasing member is disposed within the accommodating space and located on the side of the clamping members facing the large-diameter end, the biasing member being able to push the clamping members towards the small-diameter end to bring the clamping members closer together to position the wire.

[0007] Another technical aspect of the present invention is that the outer wall surface of the clamping member has a gap above and below the contact position with the outer shell along the axial direction.

[0008] Another technical aspect of the present invention is that the inner wall surface has an inclined section, one end of which surrounds the large-diameter end and the other end of which surrounds the small-diameter end, and the diameter of the inclined section gradually decreases from the large-diameter end to the small-diameter end.

[0009] Another technical aspect of the present invention is that the inclined section of the inner wall surface of the outer shell has a fixed slope, and the outer wall surface of the clamping member is tangent to the inclined section of the inner wall surface of the outer shell with its arc-shaped surface.

[0010] Another technical aspect of the present invention is that the inner wall surface has an inclined section and an extension section connected to the lower part of the inclined section, one end of the inclined section surrounds to form the large-diameter end, and one end of the extension section surrounds to form the small-diameter end.

[0011] Another technical aspect of the present invention is that each of the clamping members also has a clamping groove facing another clamping member, the clamping groove extending along the axial direction of the housing.

[0012] Another technical aspect of the present invention is that the clamping groove of each of the clamping members is formed with a rough surface or an internal thread.

[0013] Another technical aspect of the present invention is that the fixing mechanism further includes an upper cover disposed at the top of the housing, and the biasing member abuts against the upper cover and the clamping member.

[0014] Another technical aspect of the present invention is that the inclined section of the inner wall surface of the outer shell has a fixed slope, and the outer wall surface of the clamping member is tangent to the inclined section of the inner wall surface of the outer shell with its arc-shaped surface.

[0015] Another technical aspect of the present invention is that the fixing mechanism further includes a release member disposed within the accommodating space and located on the side of the clamping member facing the small-diameter end. The bottom of the housing has a perforation, and the release member has a push rod extending through the perforation and a flange extending radially outward from the top end of the push rod. The diameter of the flange is larger than the diameter of the perforation, and a portion of the push rod protrudes from the perforation.

[0016] Another technical aspect of the present invention is that the fixing mechanism further includes a threaded engagement member attached to the push rod of the detaching member, wherein the outer ring surface of the push rod is formed with an external thread for the threaded engagement member to be threaded.

[0017] Another technical aspect of the present invention is that the outer ring surface of the push rod has at least one anti-rotation plane extending along its axial direction, and the shape of the perforation of the housing matches the anti-rotation plane.

[0018] Another object of the present invention is to provide a lamp.

[0019] The luminaire includes at least one fixing mechanism as described above, a wire passing through the fixing mechanism, and a light source connected to the wire.

[0020] The luminaire includes at least one fixing mechanism as described above, a wire passing through the fixing mechanism, and a light source connected to the wire, wherein the push rod of the release member of the fixing mechanism is fixed to the external environment with the screw member, so that the wire can be positioned or slid relative to the external environment.

[0021] The advantage of this invention is that the outer wall surface of the clamping member is arc-shaped, which reduces the contact area with the inner wall surface of the outer shell, thereby reducing the friction between the outer shell and the clamping member, making it easier for the release member to push the clamping member and improving the ease of operation.

[0032] The relevant patent features and technical content of this invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. It should be noted before the detailed description that similar elements are designated with the same reference numerals.

[0033] See Figure 1 and Figure 2 The first preferred embodiment of the fixing mechanism of the present invention includes a housing 2, a top cover 3 disposed at the top of the housing 2, and a plurality of clamping members 4, a release member 5, and a biasing member 6 respectively disposed in the housing 2. The clamping member 4 is located between the release member 5 and the biasing member 6, and one end of the biasing member 6 abuts against the top cover 3, and the other end of the biasing member 6 abuts against one end of the clamping member 4.

[0034] like Figure 2 As shown, the outer casing 2 has an inner wall surface 21 surrounding an accommodating space 22 that communicates with the outside and extends axially along the outer casing 2. The accommodating space 22 has a large-diameter end 221 and a small-diameter end 222. It should be noted that, in this embodiment, the inner wall surface 21 has an inclined section 211 and an extension section 212 connecting the lower part of the inclined section 211. One end of the inclined section 211 surrounds the large-diameter end 221, and one end of the extension section 212 surrounds the small-diameter end 222. The diameter of the inclined section 211 gradually decreases towards the extension section 212, while the diameter of the extension section 212 remains constant and is the same as the minimum diameter of the inclined section 211. In some embodiments, the inner wall surface 21 may only have the inclined section 211, one end of which surrounds to form the large-diameter end 221, and the other end of which surrounds to form the small-diameter end 222. The diameter of the inclined section 211 gradually decreases from the large-diameter end 221 toward the small-diameter end 222.

[0035] The clamping member 4 is disposed within the inclined section 211 of the accommodating space 22. Each clamping member 4 has an outer wall surface 41 facing the inner wall surface 21 of the housing 2, and a clamping groove 42 facing the other clamping member 4. The clamping groove 42 extends along the axial direction of the housing 2. The outer wall surface 41 has an arc-shaped cross-section along the axial direction and partially contacts the inner wall surface 21.

[0036] The release element 5 is hollow and is disposed within the accommodating space 22, located on the side of the clamping member 4 facing the small-diameter end 222. A portion of the release element 5 protrudes from the outer shell 2. In this embodiment, the release element 5 is disposed within the extension section 212. The bottom of the outer shell 2 has a through hole 20. The release element 5 has a push rod 51 extending through the through hole 20 and a flange 52 extending radially outward from the top end of the push rod 51. The diameter of the flange 52 is larger than the diameter of the through hole 20, and a portion of the push rod 51 protrudes from the through hole 20.

[0037] The biasing member 6 is disposed within the accommodating space 22 and between the clamping member 4 and the upper cover 3. In this embodiment, the biasing member 6 has a spring 61 and a ring-shaped washer 62 disposed at the bottom of the spring 61. The washer 62 increases the contact area with the clamping member 4 and also makes the force of the spring 61 pushing against the clamping member 4 more even. In some embodiments, the biasing member 6 may also be a separate spring 61 design, not limited to those disclosed in this embodiment.

[0038] See Figure 3 When the fixing device of the present invention needs to be threaded, the push rod 51 of the loosening member 5 is first pushed towards the outer shell 2, so that the flange 52 of the loosening member 5 is close to the clamping member 4, and the clamping member 4 is pushed towards the large-diameter end 221 of the accommodating space 22. At this time, the clamping member 4 will press against the spring 61 of the biasing member 6, so that it accumulates elastic restoring force. Since the diameter of the inclined section 211 gradually increases towards the large-diameter end 221, the clamping members 4 will move away from each other as they move towards the large-diameter end 221, forming a channel 40. At this time, the wire W can be sequentially passed through the loosening member 5, the channel 40, the biasing member 6, and the upper cover 3, wherein the wire W can be a suspension steel cable or an electric wire, and the width of the channel 40 is greater than the diameter of the wire W, so that the wire W can be smoothly threaded through it.

[0039] After the wire W has passed through and the fixed position of the clamping member 4 and the wire W has been determined, the force applied to the loosening member 5 can be removed. At this time, the elastic restoring force accumulated by the biasing member 6 will push the clamping member 4 towards the small-diameter end 222 of the accommodating space 22, causing the clamping member 4 to move along the inner wall surface 21 of the outer shell 2 towards the small-diameter end 222. The clamping members 4 gradually move closer to each other, narrowing the channel 40, so that the clamping members 4 fit and position the wire W. Figure 4 As shown. Since each clamping member 4 has the clamping groove 42, it does not directly squeeze the wire W. Instead, the clamping groove 42, with its rough surface or internal threads, increases friction to achieve the effect of positioning the wire W. It should also be noted that the inclined section 211 has a fixed slope, and the outer wall surface 41 of the clamping member 4 forms partial contact with the inclined section 211 by its arc-shaped surface. Therefore, the contact position between the outer wall surface 41 of the clamping member 4 and the outer shell 2 has a gap G along the axial direction, both above and below. Because the clamping member 4 and the outer shell 2 only have partial contact, and the contact area is small, the friction is also small, making it easier for the release member 5 to push the clamping member 4, thus improving operational convenience.

[0040] See Figure 5In another preferred embodiment of the fixing mechanism of the present invention, the aforementioned loosening member 5 may be omitted. Another preferred embodiment of the fixing mechanism of the present invention includes a housing 2, a top cover 3 disposed at the top of the housing 2, a plurality of clamping members 4 disposed within the housing 2, and a biasing member 6. One end of the biasing member 6 abuts against the top cover 3, and when the other end of the biasing member 6 abuts against one end of the clamping member 4, the other end of the clamping member 4 extends outside the housing 2. At this time, the wire W is clamped by the clamping member 4 and cannot move relative to the clamping member 4. When the user wants to adjust the height of the lamp, they only need to push the clamping member 4 towards the top cover 3 to loosen the wire W. After adjusting the height of the lamp, the clamping member 4 can be released, and the elastic restoring force of the biasing member 6 is used to position the relative position of the wire W and the clamping member 4.

[0041] The fixing mechanism of the present invention can achieve the following effects through the above-described method:

[0042] 1. Easy to operate: Since the outer wall surface 41 of the clamping groove 42 is arc-shaped, it will only partially contact the inner wall surface 21. The contact position of this part has a gap G above and below the axial direction of the outer shell 2, thereby reducing the friction between the clamping member 4 and the outer shell 2, making it easier for the release member 5 to push the clamping member 4 and improving the ease of operation.

[0043] 2. Avoid damage to wire W: The clamping member 4 has the clamping groove 42. Therefore, when the clamping member 4 positions the wire W, it will not directly squeeze the wire W. Instead, the clamping groove 42 has a rough surface or internal thread to increase friction and position the wire W, thus avoiding damage to the wire W and extending the service life of the wire W.

[0044] See Figure 6 This is a second preferred embodiment of the fixing mechanism of the present invention, which also includes a housing 2, a top cover 3 disposed at the top of the housing 2, and a plurality of clamping members 4, a releasing member 5, and an biasing member 6 respectively disposed within the housing 2. The difference is that this second preferred embodiment also includes a screw member 8 engaged with the releasing member 5. It should be particularly noted that, as... Figure 7 As shown, Figure 6 The enlarged view of section A in the middle frame shows that the outer ring surface of the push rod 51 has at least one anti-rotation plane 511 extending along its axial direction. The shape of the through hole 20 in the housing 2 matches the anti-rotation plane 511, for example... Figure 7 The plane 201 of the perforation 20 shown can restrict the rotation of the loosened part 5.

[0045] See Figure 8 and cooperate Figure 7The fixing mechanism of the present invention can be combined with the external environment 9, which has a mounting hole 91. The push rod 51 of the loosening member 5 passes through the mounting hole 91, and the screw-fitting member 8 is then screwed onto the push rod 51 from below. The push rod 51 has an anti-rotation plane 511, and the through hole 20 of the housing 2 has two planes 201 that mate with the anti-rotation plane 511. Therefore, when the screw-fitting member 8 is engaged, the loosening member 5 will not rotate and can smoothly perform the screwing operation.

[0046] Furthermore, when the fixing mechanism of the present invention is applied to a suspended lighting fixture, the fixture includes four wires W, such as... Figure 9 and Figure 10 As shown, one end of the wire W that is connected to the lamp is fixed, and the other end of the wire W is connected to the screw 8 (see figure) by the push rod 51 of the fixing mechanism of the present invention. Figure 8 Fixed to the external environment 9 (ceiling), when the suspension height of the light fixture needs to be adjusted, the excess wire W can be stored above the ceiling. This simplifies and simplifies the adjustment process, resulting in a cleaner and more aesthetically pleasing appearance without any tangled wires. In another embodiment, the fixing structure can also be located at the end of the wire W closest to the light fixture. When the suspension height needs to be adjusted, the excess wire W can then be stored within the interior space of the light fixture.

[0047] In summary, the fixing mechanism and lamp of the present invention, by means of the arc-shaped outer wall surface 41 of the clamping member 4, can reduce the contact area with the inner wall surface 21 of the outer shell 2, thereby reducing the friction between the outer shell 2 and the clamping member 4, making it easier for the releasing member 5 to push the clamping member 4 and improving operational convenience. At the same time, the design of the clamping groove 42 of the clamping member 4 can reduce damage to the wire W and extend the service life of the wire W, effectively achieving the purpose of the present invention.

[0048] However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
