DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0027] As Figures 1-5 Indicated, a kind of small-angle LED linear light source's lamp bead protection device, including base plate 1, the upper side of base plate 1 is close to the position of front and back two sides and is equipped with several rectangularly distributed positioning holes 2, the upper side of base plate 1 is fixedly connected with several linearly distributed lamp beads 3, the outside of several lamp beads 3 is all fixedly connected with colloid 4, the outside of several colloid 4 is all movably sleeved with protection mechanism 5, the outside of protection mechanism 5 is movably sleeved with stabilizing mechanism 6;

[0028] Protection mechanism 5 includes cover body 51, the outside of cover body 51 is fixedly connected with four annularly distributed elastic jaws 52, the upper side of base plate 1 is equipped with several evenly distributed fixed holes 53, and fixed hole 53 is annularly distributed four around colloid 4, the outside of elastic jaw 52 is movably sleeved in the inside of fixed hole 53;

[0029] Stabilizing mechanism 6 includes fixed plate 61, the lower side of base plate 1 is overlapped on the upper side of fixed plate 61, the upper side of fixed plate 61 is equipped with several evenly distributed limiting holes 62, the outside of elastic jaw 52 is movably sleeved in the inside of limiting hole 62 close to the position of bottom.

[0030] It should be noted that the shape of the elastic clamping jaw 52 is wedge-shaped, so that when the elastic clamping jaw 52 is inserted into the fixing hole 53, the elastic clamping jaw 52 first deforms elastically, and then resets after the cover body 51 is installed in place, so that the substrate 1 fixes the elastic clamping jaw 52, at this time the lamp bead 3 is just in the middle of the inside of the cover body 51, convenient to install and operate, the limiting hole 62 is used to fix the elastic clamping jaw 52, so that the bottom of the elastic clamping jaw 52 is limited and cannot be taken out from the inside of the fixing hole 53.

[0031] As shown in Figure 3 , the position of the outer side of the four elastic clamping jaws 52 near the bottom is shaped as an isosceles trapezoid.

[0032] It should be noted that the shape of the elastic clamping jaw 52 is convenient to insert the inside of the limiting hole 62, avoiding mutual interference of the edges.

[0033] As shown in Figure 3 , the upper side of the fixed plate 61 is fixedly connected with a plurality of rectangularly distributed positioning blocks 63, and the outer side of the positioning block 63 is movably sleeved on the inside of the positioning hole 2.

[0034] It should be noted that the positioning block 63 cooperates with the positioning hole 2 to cause the limiting hole 62 to quickly align with the elastic clamping jaw 52, avoiding the problem that the inner diameter of the limiting hole 62 is too small, causing the limiting hole 62 to be difficult to align with the elastic clamping jaw 52.

[0035] As shown in Figure 3 , the outer side of the cover body 51 movably sleeves a stabilizing plate 64, the lower side of the stabilizing plate 64 is fixedly connected with a plurality of rectangularly distributed fixed columns 65, the outer side of the fixed column 65 movably sleeves on the inside of the positioning block 63, the inside of the plurality of fixed columns 65 movably sleeves a fixed block 66, and the lower side of the fixed block 66 is a circular plate located on the lower side of the fixed plate 61.

[0036] It should be noted that the stabilizing plate 64 is used to protect the cover body 51, so that a plurality of cover bodies 51 form a whole, enhancing the stability of the cover body 51, and at the same time the stabilizing plate 64 can be divided into multiple parts, reducing the production cost of the stabilizing plate 64.

[0037] As shown in Figure 3 , the inside of the stabilizing plate 64 fixedly sleeves a plurality of linearly distributed elastic rings 67, and the elastic ring 67 is located on the outside of the cover body 51.

[0038] It should be noted that the elastic ring 67 is used to reduce the wear of the stabilizing plate 64 on the outside of the cover body 51, prolonging the service life of the component.

[0039] As shown in Figure 4 , the shape of the outside of the cover body 51 is conical, and the shape of the inside is inverted conical.

[0040] It needs to be explained that the shape of the cover body 51 is such that the inner side of the stabilizing plate 64 is inverted conical, which makes the stabilizing plate 64 can generate a downward force on the cover body 51.

[0041] As Figure 5 It is shown that the fixed block 66 and the fixed plate 61 are made of opaque materials.

[0042] It needs to be explained that the material selection of the fixed plate 61 and the fixed block 66 avoids the problem that the light passes through the gap between the positioning hole 2 and the positioning block 63 and propagates to the rear side.

[0043] The working principle of the utility model is: first, the shape of the elastic clamping jaw 52 is wedge-shaped, so that the elastic clamping jaw 52 first generates elastic deformation when being inserted into the fixed hole 53, and then resets after the cover body 51 is installed in place, so that the base plate 1 fixes the elastic clamping jaw 52, at this time, the lamp bead 3 is just in the middle of the inner side of the cover body 51, convenient to install and operate, the elastic clamping jaw 52 is movably sleeved into the fixed hole 53, so that the cover body 51 is fixed on the base plate 1, the connection between the base plate 1 and the cover body 51 is enhanced, the material cost required by using adhesive material is reduced, and the installation cost of aligning the lamp bead 3 with the middle of the inner side of the cover body 51 is reduced, finally, the limiting hole 62 is used to fix the elastic clamping jaw 52, so that the bottom of the elastic clamping jaw 52 is limited and cannot be taken out from the inner side of the fixed hole 53, the stabilizing plate 64 is used to protect the cover body 51, so that a plurality of cover bodies 51 form a whole, the stability of the cover body 51 is enhanced, the stabilizing plate 64 can be divided into multiple parts, the production cost of the stabilizing plate 64 is reduced, the cover body 51 is fixed as a whole through the action of the fixed plate 61 and the stabilizing plate 64, the collision of the cover body 51 caused by external environment is avoided, and the protection of the lamp bead 3 by the cover body 51 is more stable.

[0044] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
