[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0048] Example 1:

[0049] Please see Figures 1-4 This embodiment provides an installation structure 100, including a lamp body 1, a sealing element 2, an end cap 3, and fasteners 4. Specifically, the lamp body 1 includes a lamp housing 11 and connecting ends 12 disposed at both ends of the lamp housing 11. An installation space 111 is provided inside the lamp housing 11, and the installation space 111 is connected to the external space through the connecting ends 12, which are provided with positioning grooves 121. The sealing element 2 includes a first sealing body 21, a second sealing body 22 disposed inside the first sealing body 21, and a receiving groove 23 disposed between the first sealing body 21 and the second sealing body 22, the receiving groove 23 being provided with positioning bosses 231. At the end of the sealing element 2 facing the lamp body 1, the second sealing body 22 protrudes from the first sealing body 21. The end cap 3 is provided with a receiving cavity 31, and the sealing element 2 is located within the receiving cavity 31.

[0050] Furthermore, the side of the seal 2 with the positioning boss 231 faces the connecting end 12, and the positioning boss 231 is engaged with the positioning groove 121. The connecting end 12 is fitted into the receiving groove 23 and sealed by the first sealing body 21 and the second sealing body 22. The fastener 4 fixes the end cap 3, the seal 2 and the lamp body 1 together, and the first sealing body 21 is located entirely in the receiving cavity 31.

[0051] During installation, since the second sealing body 22 protrudes from the first sealing body 21, it first enters the installation space 111, providing guidance and initial positioning for the seal 2 during installation, reducing the difficulty of aligning the seal 2. In this embodiment, there are two positioning grooves 121, symmetrically arranged at the connecting end 12. Correspondingly, there are also two positioning bosses 231, which enter the receiving groove 23 at the connecting end 12. The positioning bosses 231 cooperate with the positioning grooves 121 to achieve precise positioning of the seal 2. Under the combined action of the second sealing body 22 and the positioning bosses 231, the installation and positioning of the seal 2 at the connecting end 12 is accurate and efficient.

[0052] When the connecting end 12 is fitted into the accommodating groove 23 and the positioning boss 231 is inserted into the positioning groove 121, the fastener 4 passes through the end cover 3 and the sealing member 2, and is then locked and fixed with the lamp body 1, so that the end cover 3, the sealing member 2 and the lamp body 1 are fixedly connected together. During the locking process of the fastener 4, the sealing member 2 disposed in the accommodating cavity 31 is extruded and deformed by the end cover 3 and the connecting end 12, so as to achieve the final sealing and locking effect. Compared with the existing end face sealing method, the cooperation between the compression-deformed sealing member 2 and the wrapped connecting end 12 enables better overall sealing performance.

[0053] In addition, the first sealing body 21 is integrally located in the accommodating cavity 31, so that the deformation of the first sealing body 21 is controllable when it is compressed for sealing, which ensures that the sealing of the connecting end 12 by the first sealing body 21 is effective.

[0054] In some embodiments, the first sealing body 21 and the second sealing body 22 are respectively provided with a first flange 211 and a second flange 221, the second flange 221 is inserted into the installation space 111, and the first flange 211 is closely attached and connected to the outer side of the lamp housing 11. The guiding function is realized through the insertion of the second flange 221, and the second flange 221 does not contact the inner side of the connecting end 12 facing the installation space 111, which reduces the alignment requirement for the installation of the sealing member 2 and makes the installation quicker. When the connecting end 12 enters the accommodating groove 23, the first flange 211 then closely seals the outer side of the lamp housing 11.

[0055] Further, in the accommodating groove 23, the positioning boss 231 extends from the first flange 211 toward the second flange 221, and the positioning boss 231 is connected to the first flange 211, which facilitates the molding and production of the sealing member 2. Both the first flange 211 and the positioning boss 231 closely seal the outer side of the lamp housing 11, which further ensures the effectiveness of sealing while ensuring accurate positioning.

[0056] In some other embodiments, the groove bottom of the accommodating groove 23 is an arc-shaped structure or a planar structure. Correspondingly, the shape of the connecting end 12 is consistent with that of the groove bottom of the accommodating groove 23, which ensures that the connecting end 12 fits with the groove bottom of the sealing groove when the sealing member 2 deforms, thereby improving the sealing effect. In the present embodiment, the groove bottom of the accommodating groove 23 is a planar structure, which is easier to implement and measure during production. However, for applications with strict service life requirements, arranging the groove bottom of the accommodating groove 23 as an arc-shaped structure can effectively avoid problems such as aging and fracture at the corners in the accommodating groove 23 and reduce uneven stress on the groove bottom of the accommodating groove 23.

[0057] In a further embodiment, the end face of the sealing member 2 away from the lamp body 1 is a base surface 24, the distances from the first flange 211, the second flange 221 and the positioning boss 231 to the base surface 24 are L1, L2 and L3 respectively, which satisfy the relational expression: L3=L1<L2. Please continue to refer Figures 2-4, when L3=L1, the positioning boss 231 is flush with the end of the first convex edge 211 facing one side of the lamp housing 11, which facilitates demolding during the production of the sealing member 2. When L1<L2, the second convex edge 221 can provide guidance during installation before the connecting end 12 enters the accommodating groove 23.

[0058] Further, the distance between the groove bottom of the accommodating groove 23 and the base surface 24 is L4, satisfying the relational expression: L4=L1 / 2. In the sealing member 2, the area between the groove bottom of the accommodating groove 23 and the base surface 24 is locked and squeezed by the fastener 4, and meanwhile the first convex edge 211 is tightly attached to the outer side of the lamp housing 11 for sealing. If the dimensions of the two parts are unreasonable, the sealing effect of the sealing member 2 will be greatly reduced, or the material of the sealing member 2 will be wasted and the cost will be increased. When L4=L1 / 2, the connecting end 12 abuts against the groove bottom, the length of the deformation area of the sealing member 2 is equal to that of the sealing fitting area, which satisfies the sealing effect of the sealing member 2 on the connecting end 12 and at the same time enables the material utilization rate of the sealing member 2 to reach a relatively optimal configuration. The specific values of L1 and L4 need to be determined according to the actual size of the sealing member 2 and the wall thickness of the lamp housing 11, and will not be repeated herein.

[0059] To sum up, in the mounting structure provided in this embodiment, guidance and positioning are completed jointly by the second sealing body and the positioning boss, which ensures accurate mounting and positioning of the sealing member at the connecting end and improves the assembling efficiency of the sealing member. In addition, in the mounting structure, the connecting end is fittingly connected in the accommodating groove, and then the end cover, the sealing member and the lamp body are fixedly connected together by fasteners, and the compression-deformed sealing member cooperates with the wrapped connecting end, so that the overall sealing performance is better.

[0060] Example 2:

[0061] Please refer to Figures 1-4 on the basis of Figures 5-6 . This embodiment is an optimization and adjustment based on the mounting structure 100 described in Example 1. The difference between this embodiment and Example 1 lies in that: the connecting end 12 is further provided with a mounting post 122, the mounting post 122 protrudes toward the mounting space 111 and is provided with a mounting hole 1221. A first through hole 2311 is provided in the accommodating groove 23, a second through hole 32 is provided on the end cover 3, and the fastener 4 respectively passes through the second through hole 32 and the first through hole 2311 and is fixedly mounted in the mounting hole 1221.

[0062] After the fastener 4 is fixedly installed in the mounting hole 1221, the first through hole 2311, located in the receiving groove 23, surrounds the fastener 4 and is sealed under pressure, ensuring that humid air and other contaminants will not enter the mounting space 111 from the installation position of the fastener 4. The mounting post 122, located within the mounting space 111, facilitates production and reduces the overall size of the linear light. The first protruding edge 211 and the positioning boss 231 are located on the outer side of the lamp housing 11 to achieve a seal, while the second protruding edge 221 surrounds the inner sidewall of the connecting end 12 to provide guidance. In this embodiment, the fastener 4 is a screw, and the mounting hole 1221 is a threaded hole that does not communicate with the mounting space 111. The mounting post 122, similar to the positioning groove 121, is also symmetrically arranged.

[0063] In some embodiments, at the end of the seal 2 away from the lamp body 1, the positioning boss 231 is recessed 2312 from the end face toward the lamp body 1. Correspondingly, on the end cap 3, a countersunk structure 33 is provided at the position of the second through hole 32. The countersunk structure 33 cooperates with the recess 2312 to achieve the installation positioning between the seal 2 and the end cap 3, thereby ensuring that the first through hole 2311 and the second through hole 32 are coaxial before the fastener 4 is tightened, which facilitates the installation and tightening of the fastener 4 and ensures the effective sealing at the position of the first through hole 2311.

[0064] Furthermore, the positioning boss 231 is interference-fitted into the positioning groove 121. In this embodiment, the positioning boss 231 has a wedge-shaped or conical structure along the end cover 3 toward the lamp body 1, with the smaller end facing the lamp body 1. When the positioning boss 231 is first inserted into the positioning groove 121, there is a large gap between it and the positioning groove 121, which facilitates the guidance of the positioning boss 231 during the insertion process. As the depth of the positioning boss 231 increases, the gap becomes smaller and smaller until the positioning boss 231 abuts against the positioning groove 121. At this time, by tightening the fastener 4, the positioning boss 231 is interference-fitted into the positioning groove 121, realizing the precise positioning of the seal 2 and the connecting end 12, and at the same time, improving the sealing effect of the seal 2 on the connecting end 12.

[0065] In this embodiment, the end cap 3 includes a base plate 34 and a surrounding edge 35, and the receiving cavity 31 is formed by the base plate 34 and the surrounding edge 35. The sealing member 2 is disposed in the receiving cavity 31 around the surrounding edge 35, thereby reducing the overall size of the end cap 3 and improving space utilization. In other embodiments, the receiving cavity 31 is also provided with a receiving structure for limiting the sealing member 2. The sealing member 2 can be fixed to the end cap 3 in advance by the receiving structure, and then fixed together with the sealing member 2 to the connecting end 12 by the fastener 4.

[0066] The installation structure provided in this embodiment further improves the sealing effect of the connection end and the ease of installation by providing a first through hole, a second through hole, and a mounting hole.

[0067] Example 3:

[0068] Please Figures 1-6 Based on the above Figures 7-8 This embodiment provides a linear light 200, which includes a light-emitting component 5 and an installation structure 100 of either embodiment 1 or embodiment 2, wherein the light-emitting component 5 is disposed in the installation space 111.

[0069] In this embodiment, to facilitate the installation of the light-emitting component 5 within the installation space 111, a slot 1111 is provided within the receiving space. The light-emitting component 5 enters the installation space 111 through the connecting end 12, and after being inserted into the slot 1111, it is fixed within the installation space 111. Then, the connecting ends 12 at both ends are sealed using accessories such as the sealing element 2, end cap 3, and fastener 4, thus completing the assembly of the linear light 200. Of course, in other embodiments, the light-emitting component 5 can also be fixed in other ways, such as by magnetic attraction or by locking it to the installation space 111 using fastener 4.

[0070] In addition, in this embodiment, the positioning groove 121 and the mounting post 122 are integrally formed onto the lamp housing 11 through processes such as stamping, die casting, or injection molding, simplifying the structure of the lamp body 1. A sealing cover 6 is also provided at the position where the fastener 4 is fixed to the end cover 3. The sealing cover 6 is fastened to the outside of the fastener 4 to protect it, further preventing humid air, dust, etc., from entering the installation space 111 from the fastener 4, thus improving the overall service life of the linear light 200.

[0071] In summary, the linear light provided in this embodiment, after adopting the installation structure of Embodiment 1 or Embodiment 2, has higher sealing performance and protection reliability of the light body, longer service life, and at the same time reduces assembly difficulty and improves production line capacity and production efficiency.

[0072] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
