[0002] In the existing eyeglass leg structures, most of the eyeglass leg lengths are fixed at a certain size, and some require screws or other pin fixing structures to adjust the length of the eyeglass leg. Most of the eyeglass legs with a fixed length are extremely inconvenient for children in the growing period. The head growth of children in the growing period makes the fixed size of the eyeglass legs unfit, and they often need to be replaced according to the growth situation. In addition, the active personality of children makes it easy for the glasses with inappropriate eyeglass leg sizes to fall off.
[0003] Some glasses legs that require screws or other pin-fixing structures to fix the length are also inconvenient for children. Although they can change the function of long-term length adjustment for children in the growth period, they are also easily damaged due to falling during exercise. Summary of the invention

[0006] Preferably, the elastic insert is an elastic plate formed at the tail of the temple, one end of the elastic plate is connected to the tail of the temple to form a barb shape, and the clamping block is formed on the outside of the elastic plate.
[0007] Furthermore, the other end of the elastic plate is connected to the tail of the temple, and the elastic plate and the tail of the temple form a hollow structure.
[0008] Furthermore, the elastic plate forms a concave portion toward the inside of the hollow structure, and the elastic plate is formed into an outwardly arched shape.
[0009] Preferably, the positioning groove is formed with a plurality of slots along the adjustment direction of the adjusting rod sleeve, and the clamping block can be clamped and connected in any of the slots.
[0010] Furthermore, the card blocks are formed in pairs, and the pair of card blocks are arranged along the direction in which the plurality of slot holes are formed.
[0011] Preferably, anti-slip teeth are formed on the glasses leg, and the anti-slip teeth are formed with an inclined surface on one side toward the tail of the glasses leg and a vertical surface on the other side; a groove is formed on the adjusting rod sleeve, and the anti-slip teeth can move in the groove.
[0012] Furthermore, the anti-slip teeth are arranged at the rear of the elastic inserting strip, and the strip groove is arranged at the rear of the adjusting rod sleeve.

[0024] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.
[0025] Example 1
[0026] according to Figure 1-3 As shown in 6-8, a new type of hidden adjustable eyeglass leg structure includes an eyeglass leg 1 and a foot cover 2 sleeved at the end of the eyeglass leg 1, and a length adjustment device is arranged between the eyeglass leg 1 and the foot cover 2, and the length adjustment device includes an elastic insert 3 arranged at the end of the eyeglass leg 1, a block 31 formed on the elastic insert 3, an adjustment rod cover 4 sleeved outside the elastic insert 3, and a positioning groove 41 formed in the adjustment rod cover 4 and matched with the block 31, and the foot cover 2 is sleeved outside the adjustment rod cover 4, so that the length adjustment device is hidden in the foot cover 2, and the foot cover 2 can hide the entire length adjustment device. The elastic insert 3 and the eyeglass leg 1 can be made of high elastic injection molding material, or can be a high elastic metal material for installation; the adjustment rod cover 4 is made of soft elastic material; the foot cover 2 is made of elastic injection molding material.
[0027] The elastic insert 3 is an elastic plate 32 formed at the tail of the eyeglass leg 1, one end of the elastic plate 32 is connected to the tail of the eyeglass leg 1 to form a hook shape, and the clamping block 31 is formed on the outside of the elastic plate 32. The cantilever formed by the elastic plate 32 can swing relative to the tail of the eyeglass leg 1, so that the clamping block 31 can be clamped or detached from the positioning groove 41.
[0028] The positioning groove 41 is formed with a plurality of slots along the adjustment direction of the adjusting rod sleeve 4, and the clamping block 31 can be clamped and connected in any of the slots; and in order that the clamping block 31 can be relatively firmly clamped and connected in the slots, the clamping block 31 is formed in a pair, and the pair of the clamping blocks 31 are arranged along the direction in which the plurality of the slots are formed, and the pair of the clamping blocks 31 can be clamped and fixed in two adjacent slots.
[0029] The tail of the adjusting rod sleeve 4 is formed with an inserting tongue 43, and the head of the foot sleeve 2 is formed with a slot 21. The inserting tongue 43 is inserted and fixed in the slot 21. The inserting tongue 43 and the slot 21 make the connection between the foot sleeve 2 and the length adjustment device more firmly. Example 2
[0030] The difference from Example 1 is: Figure 4-5 As shown, the other end of the elastic plate 32 is connected to the tail of the eyeglass leg 1, and the elastic plate 32 and the tail of the eyeglass leg 1 form a hollow structure 33. The elastic plate 32 is squeezed into the hollow structure 33 and can also swing relative to the tail of the eyeglass leg 1. Example 3
[0031] The difference from Example 2 is: Figure 4-5 As shown, in order to enhance the elasticity of the elastic plate 32 in the hollow structure 33, the elastic plate 32 forms a recess 34 inside the hollow structure, and the elastic plate 32 is formed into an outward arch, which can increase the amplitude of the elastic deformation of the elastic plate 32 without increasing the protrusion of the block 31. Example 4
[0032] The difference from Example 1 is: Figure 1-8 As shown, an anti-slip tooth 5 is formed on the eyeglass leg 1, and the anti-slip tooth 5 is formed with an inclined surface on one side toward the tail of the eyeglass leg 1, and is clamped in the adjusting rod sleeve 4 along the eyeglass leg 1, and the other side is a vertical surface, so that the eyeglass leg 1 clamped in the adjusting rod sleeve 4 cannot be easily pulled out; a groove 42 is formed on the adjusting rod sleeve 4, and the anti-slip tooth 5 can move in the groove 42; the anti-slip tooth 5 is arranged at the rear of the elastic insert 3, and the groove 42 is arranged at the rear of the adjusting rod sleeve 4.
[0033] After the inclined surface of the anti-slip tooth 5 enters the strip groove 42, the anti-slip tooth 5 can move in the strip groove 42, which can play the role of positioning and guide rail; when the anti-slip tooth 5 tends to separate from the strip groove 42, the vertical surface of the anti-slip tooth 5 will be stuck on the edge of the strip groove 42, making it difficult to separate from the strip groove 42.
[0034] Working principle:
[0035] During assembly, the elastic strip 3 at the tail of the eyeglass leg 1 is inserted into the adjusting rod sleeve 4. Under the elastic action of the elastic plate 32, the clamping block 31 can compress the elastic plate 32 and reach the slot position of the positioning groove 41. The anti-slip teeth 5 also enter the strip groove 42 under the action of the inclined surface. The adjusting rod sleeve 4 is inserted into the foot sleeve 2 together with the elastic strip 3, and the entire length adjustment device is hidden by the foot sleeve 2.
[0036] When adjusting, no tools are needed. Under the elastic action of the elastic plate 32, the glasses leg 1 can be pushed forward and backward, and the clamping block 31 is clamped and connected to the corresponding appropriate slot and fixed, so that the length of the glasses leg 1 can be adjusted.
