Description

Technical Field

[0001] This utility model relates to the field of pearl jewelry fixing technology, and in particular to a fixing structure for pearl jewelry. Background Technology

[0002] Pearls are a common type of jewelry and play a crucial role in adornment. They are often attached to rings, brooches, and other decorative items to enhance their beauty.

[0003] The current method of connecting pearls to ornaments usually involves drilling a hole in the pearl, then inserting the fixing part of the ornament through the hole from one end of the pearl and extending it to the other end. The disadvantages of this method are that the other end of the fixing part will be exposed outside the pearl, which firstly affects the appearance, secondly makes the pearl prone to shaking, and the connection effect is not good. Furthermore, drilling a hole through the entire pearl also reduces the hardness of the pearl, making it more brittle. Therefore, we propose a fixing structure for pearl jewelry to solve the above problems. Utility Model Content

[0004] This utility model provides a fixing structure for pearl jewelry, which solves the technical problem of poor connection between pearls and decorative parts.

[0005] To solve the above-mentioned technical problems, this utility model provides a fixing structure for pearl jewelry, including a pearl body, a deep hole in the pearl body, an extrusion block in the deep hole, a threaded hole in the extrusion block, an expansion sleeve in the deep hole, and a screw pusher in the expansion sleeve with its outer end fixed to the decorative piece. The screw pusher is threadedly connected to the threaded hole, so that at least a portion of the outer wall of the expansion sleeve contacts and is fixed to the wall of the deep hole.

[0006] Preferably, the expansion sleeve has a first deformation pre-opening near the end of the extrusion block, and the expansion sleeve has a second deformation pre-opening near the deformation pre-opening.

[0007] The above technical solution is adopted: a first deformation pre-opening is provided at the end of the expansion sleeve near the extrusion block, and a second deformation pre-opening is provided at the end of the expansion sleeve near the deformation pre-opening. When the screw pusher is threadedly connected to the extrusion block, the extrusion block is squeezed into the expansion sleeve as the screw pusher rotates, causing the expansion sleeve to expand. When the end of the expansion sleeve expands, it is easy to twist near the expansion sleeve. However, the first deformation pre-opening and the second deformation pre-opening can prevent the expansion sleeve from twisting and make the expansion sleeve expand better.

[0008] Preferably, the expansion sleeve has at least a partial space between its circumferential direction and the depth hole.

[0009] The above technical solution is adopted in which at least a portion of space is provided between the expansion sleeve and the deep hole in the circumferential direction, so as to facilitate the screw pusher to push the expansion sleeve to move in the deep hole.

[0010] Preferably, four of each of the first and second deformation pre-openings are provided and are arranged symmetrically.

[0011] The above technical solution is adopted: by setting four of the first deformation pre-opening and the second deformation pre-opening and symmetrically arranged, the expansion sleeve will not twist at the waist when it expands.

[0012] Preferably, an arc-shaped surface extending from the outside to the inside is provided along the circumference of the expansion.

[0013] The above technical solution is adopted: by setting an arc-shaped surface from the outside to the inside along the circumference of the expansion sleeve, it is easier for the extrusion block to be extruded into the expansion sleeve.

[0014] Preferably, the end of the screw pusher away from the extrusion block is provided with a connecting seat that is fixed to the decorative part.

[0015] The above technical solution is adopted: a connecting seat for fixing the decorative part is provided at the end of the screw pusher away from the extrusion block, which facilitates the fixed connection with the decorative part, such as a ring, brooch, etc.

[0016] Preferably, the extrusion block is conical in shape.

[0017] The above technical solution is adopted: by making the extrusion block conical, the extrusion block can be better extruded into the expansion sleeve.

[0018] Preferably, the maximum diameter of the extrusion block is the same as the diameter of the depth hole.

[0019] The above technical solution is adopted: by making the maximum diameter of the extrusion block the same as the diameter of the deep hole, the expansion generated by the expansion sleeve when the extrusion block is extruded into the expansion sleeve is sufficient to fix it to the inner wall of the deep hole.

[0020] Preferably, the extrusion block is further provided with extrusion teeth.

[0021] The above technical solution is adopted: the extrusion block is also provided with extrusion teeth. When the extrusion teeth are extruded into the inner wall of the expansion sleeve, the outer wall of the expansion sleeve will also be toothed, which increases the friction between the outer wall of the expansion sleeve and the inner wall of the depth hole, thereby making the expansion sleeve more firmly fixed to the pearl body after expansion.

[0022] Preferably, the extrusion teeth are arranged in a stepped, rectangular pattern along the length of the extrusion block.

[0023] The above technical solution is adopted: the extrusion teeth are arranged in a stepped square along the length of the extrusion block. When the extrusion teeth are extruded into the inner wall of the expansion sleeve, the outer wall of the expansion sleeve also has a stepped toothed wall, which increases the friction between the outer wall and the inner wall of the deep hole.

[0024] Compared with related technologies, this utility model has the following beneficial effects:

[0025] 1. Compared with the traditional pearl fixing structure, this utility model, by setting an insertion block, an expansion sleeve, and a screw pusher, has a deep hole in the pearl body, an insertion block in the deep hole, a threaded hole in the insertion block, an expansion sleeve in the deep hole, and a screw pusher in the expansion sleeve, the outer end of which is fixed to the decorative part. The screw pusher is threadedly connected to the threaded hole, so that at least a part of the outer wall of the expansion sleeve contacts and fixes the hole wall of the deep hole. The fixing method of this application is: pushing the screw pusher with the decorative part to the insertion block, and then rotating the screw pusher, so that the insertion block is squeezed into the expansion sleeve along the screw pusher, thereby causing the expansion sleeve to expand, so that the outer wall of the expansion sleeve contacts and fixes the inner wall of the deep hole, thereby achieving a fixed connection between the pearl body and the decorative part. The beneficial effects of this application are: first, the fixing effect between the two is good, the fixing is firm, and there will be no shaking; second, the connecting part is hidden in the pearl body, which increases the aesthetics of the pearl body and the decorative part.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] like Figures 1-5 As shown, a fixing structure for a pearl ornament includes a pearl body 1, a depth hole 3 on the pearl body 1, an insert block 2 inside the depth hole 3, a threaded hole 21 inside the insert block 2, an expansion sleeve 4 inside the depth hole 3, and a screw pusher 5 inside the expansion sleeve 4 whose outer end is fixed to the ornament. The screw pusher 5 is threadedly connected to the threaded hole 21 so that at least a portion of the outer wall of the expansion sleeve 4 contacts and is fixed to the hole wall of the depth hole 3.

[0035] A deep hole 3 is provided on the pearl body 1. An insert block 2 is provided in the deep hole 3. A threaded hole 21 is provided in the insert block 2. An expansion sleeve 4 is also provided in the deep hole 3. A screw pusher 5 with its outer end fixed to the decorative part is provided in the expansion sleeve 4. The screw pusher 5 is threadedly connected to the threaded hole 21 so that at least a part of the outer wall of the expansion sleeve 4 contacts and is fixed to the hole wall of the deep hole 3. The fixing method of this application is: push the screw pusher 5 with the decorative part to the insert block 2, and then rotate the screw pusher 5 so that the insert block 2 is squeezed into the expansion sleeve 4 along the screw pusher 5, thereby causing the expansion sleeve 4 to expand, so that the outer wall of the expansion sleeve 4 contacts and is fixed to the inner wall of the deep hole 3, thereby realizing the fixed connection between the pearl body 1 and the decorative part. The beneficial effects of this application are: first, the fixing effect between the two is good, the fixing is firm, and there will be no shaking; second, the connection part is hidden in the pearl body 1, which increases the aesthetics of the pearl body 1 and the decorative part, such as a ring, brooch, etc.

[0036] Example 2

[0037] like Figures 1-5 As shown, the expansion sleeve 4 is provided with a first deformation pre-opening 41 near the end of the extrusion block 2, and the expansion sleeve 4 is provided with a second deformation pre-opening 42 near the deformation pre-opening. When the screw pusher 5 is threadedly connected to the extrusion block 2, the extrusion block 2 is extruded into the expansion sleeve 4 as the screw pusher 5 rotates, causing the expansion sleeve 4 to expand. When the end of the expansion sleeve 4 expands, it is easy to twist near the position of the expansion sleeve 4. However, the first deformation pre-opening 41 and the second deformation pre-opening 42 can prevent the expansion sleeve 4 from twisting and make the expansion sleeve 4 have a better expansion effect.

[0038] like Figure 2 As shown, the expansion sleeve 4 has at least a partial space 6 in the circumferential direction with the depth hole 3, which facilitates the screw pusher 5 to push the expansion sleeve 4 to move within the depth hole 3;

[0039] like Figure 2 As shown, four of the first deformation pre-opening 41 and the second deformation pre-opening 42 are provided and are arranged symmetrically, so that the expansion sleeve 4 will not twist at the waist when it expands.

[0040] like Figure 3 ,like Figure 4 As shown, an arc-shaped surface 43 is provided from the outside to the inside along the circumference of the expansion sleeve 4, which makes it easier for the extrusion block 2 to be extruded into the expansion sleeve 4. The end of the screw pusher 5 away from the extrusion block 2 is provided with a connecting seat 51 for fixing the decorative part, which makes it easy to fix and connect with the decorative part, such as a ring, brooch, etc.

[0041] like Figure 2 As shown, the extrusion block 2 is conical, which allows the extrusion block 2 to be better extruded into the expansion sleeve 4. The maximum diameter of the extrusion block 2 is the same as the diameter of the depth hole 3, so that when the extrusion block 2 is extruded into the expansion sleeve 4, the expansion generated by the expansion sleeve 4 is sufficient to fix it to the inner wall of the depth hole 3.

[0042] like Figure 4 , Figure 5 As shown, the extrusion block 2 is also provided with extrusion teeth 22. When the extrusion teeth 22 are extruded into the inner wall of the expansion sleeve 4, the outer wall of the expansion sleeve 4 will also be toothed, which increases the friction between the outer wall of the expansion sleeve 4 and the inner wall of the depth hole 3, thereby making the expansion sleeve 4 more firmly fixed to the pearl body 1 after expansion. The extrusion teeth 22 are arranged in a stepped square along the length of the extrusion block 2. When the extrusion teeth 22 are extruded into the inner wall of the expansion sleeve 4, the outer wall of the expansion sleeve 4 will also have a stepped toothed wall, which increases the friction between it and the inner wall of the depth hole 3.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
