Description

Technical Field

[0001] The utility model relates to the technical field of rivet fastening structures, in particular to a rivet fastening structure for knitted fabrics. Background Art

[0002] Knitted fabric is a fabric made by using knitting needles to bend yarn into loops and intertwine them with each other. It has good elasticity and softness.

[0003] When knitted fabrics (such as thin fabrics like T-shirts) are made into clothes, holes are made on the surface to install hardware accessories such as rivets. However, since knitted fabrics are made of coils that are intertwined with each other, this structure is not enough to provide sufficient support for rivet fixation. Due to the elastic properties of the loop stem and extension line of the fabric yarn coil, the hole will expand after the rivet is installed, causing the rivet to fall off.

[0004] Riveting of rivets is achieved by using their own deformation or interference fit. When rivets are used on knitted fabrics, due to the particularity of their structure, the riveting may not be firm enough, especially when subjected to tension or friction. Rivets cannot achieve a firm effect on knitted fabrics. The elasticity and softness of knitted fabrics may cause the loop stem and extension line at the opening of the knitted fabric to shift or deform during the riveting process, thereby affecting the firmness of the riveting.

[0005] Moreover, the knitted fabric will float violently when being washed, and the rivets will also shake accordingly, thereby squeezing the installation holes of the knitted fabric, causing the rivets to easily fall off the surface of the knitted fabric. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a rivet fastening structure for knitted fabrics to solve the problem proposed in the above background technology that the elasticity and softness of the knitted fabrics may cause the loop stem and extension line at the opening of the knitted fabric to shift or deform during the riveting process, thereby affecting the firmness of the riveting, and the rivets may also squeeze the installation holes of the knitted fabric when shaking, causing the rivets to easily fall off the surface of the knitted fabric.

[0007] To achieve the above object, the utility model provides the following technical solution: a rivet fastening structure for knitted fabrics, comprising:

[0008] A rivet head, wherein a rivet handle is provided at the bottom of the rivet head, a fastening adhesive layer is sleeved on the surface of the rivet handle, and a plug-in slot is provided at the bottom of the rivet handle;

[0009] A rivet column is arranged in the inner cavity of the plug-in slot, a locking ring is evenly welded on the surface of the rivet column, and a locking ring is evenly installed on the upper inner wall of the rivet handle;

[0010] The rivet rod is arranged at the bottom of the rivet column. The rivet rod is inserted into the inner cavity of the rivet column. A rivet tail is installed at the bottom of the rivet rod.

[0011] Preferably, a mounting ring is installed at the bottom of the rivet head, and a limiting plug is installed at the top of the rivet shank, and the limiting plug is embedded in the inner cavity of the mounting ring. When the rivet head and the rivet shank need to be connected, the rivet head and the rivet shank can be connected by simply embedding the limiting plug in the mounting ring, so that the rivet head and the rivet shank become separate individuals, which is convenient for separate processing of the rivet head and the rivet shank.

[0012] Preferably, a non-slip pad layer is installed on the surface of the rivet column, the diameter of the non-slip pad layer is consistent with the diameter of the plug-in slot, and the non-slip pad layer is made of rubber material. After the rivet column is inserted into the plug-in slot, the non-slip pad layer will contact the inner wall of the plug-in slot, thereby increasing the friction between the rivet column and the plug-in slot.

[0013] Preferably, the surface of the anti-skid pad layer is evenly provided with anti-skid grooves, the inner wall of the rivet handle is evenly provided with anti-skid patterns, and the anti-skid grooves are in contact with the anti-skid patterns, thereby effectively preventing the rivet column from falling off from the insertion slot.

[0014] Preferably, the locking ring and the locking ring are both annular in design, the surfaces of the locking ring are inclined in design, the bottom of the locking ring is flat in design, the upper surface of the locking ring is flat in design, and the bottom of the locking ring is inclined in design, so that the locking ring will contact the inclined surface of the locking ring when moving upward, and the locking ring will easily move to the top of the locking ring, and the upper surface of the locking ring is flat in design, so that the locking ring is not easy to fall off the surface of the locking ring.

[0015] Preferably, the rivet rod and the rivet tail are both hollow in design, a mounting hole is opened in the middle of the upper surface of the fastening rubber layer, and the rivet handle is inserted in the inner cavity of the mounting hole. When the rivet rod is subjected to pressure, the pressure will be transferred to the rivet tail, so that the rivet tail is deformed completely upward, so that it can be in close contact with the surface of the knitted fabric, thereby reinforcing the rivet.

[0016] Preferably, the fastening adhesive layer is a hot melt adhesive film layer, a cold gel layer or a thermosetting adhesive layer. The cold gel includes cooling and curing adhesives such as silk screen adhesives, silk screen inks, and shoe adhesives. The thermosetting adhesives include silicone rubbers, thermosetting inks, and other adhesives that cure after heating. Beneficial Effects

[0018] 1. The rivet fastening structure for knitted fabrics is provided with a fastening adhesive layer structure, which can be fixed at the opening of the rivet by heating and melting or first scraping and then curing during rivet installation. The yarn of the knitted fabric that is easy to be demyelinated will be adhered by the fastening adhesive layer, so that the loop stem and extension line at the opening of the knitted fabric will not be expanded due to pulling, thereby improving the fastening of the rivet installation. At the same time, when the rivet is punched for installation, the fastening adhesive layer will be hidden in the rivet, and the fastening adhesive layer will not be exposed to the outside of the rivet structure, thereby improving the aesthetics of the rivet;

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a technical solution, a rivet fastening structure for knitted fabrics, please refer to Figure 1 , comprising a rivet head 1, a rivet handle 2 is provided at the bottom of the rivet head 1, and a fastening adhesive layer 3 is sleeved on the surface of the rivet handle 2.

[0031] See also Figure 4 , a plug-in slot 4 is provided at the bottom of the rivet handle 2;

[0032] See also Figure 1 , the rivet column 5 is arranged in the inner cavity of the insertion slot 4, see Figure 3 , a locking ring 6 is evenly welded on the surface of the rivet column 5, please refer to Figure 4 , a locking ring 7 is evenly installed on the upper inner wall of the rivet handle 2;

[0033] See also Figure 3 A rivet rod 8 is disposed at the bottom of the rivet column 5, the rivet rod 8 is inserted into the inner cavity of the rivet column 5, and a rivet tail 81 is installed at the bottom of the rivet rod 8;

[0034] The fastening adhesive layer 3 is melted and solidified at the opening of the rivet, and the yarns of the knitted fabric that are easy to be demyelinated will be adhered by the fastening adhesive layer 3, so that the loop stem and extension line at the opening of the knitted fabric will not be expanded due to pulling. After the rivet is punched, the fastening adhesive layer 3 will be hidden in the rivet, so that the fastening adhesive layer 3 cannot be seen from the appearance of the rivet, thereby improving the aesthetics of the rivet. The fastening adhesive layer 3 can be compounded on the surface of the fabric or on the bottom of the fabric, and can be applied to different installation positions of the rivet. Example

[0035] The fastening adhesive layer 3 is a hot-melt adhesive film layer. After the fastening adhesive layer 3 is cut or sheared, it is placed on the knitted fabric where the rivets are installed. It is heated by a heating device such as an iron and laminated on the surface of the knitted fabric. Then, the knitted fabric is opened. Since the yarns of the knitted fabric have been bonded, the holes will not be enlarged due to the pulling of the fabric. Example

[0036] The fastening adhesive layer 3 is a cold gel layer. The cold gel includes cooling and curing adhesives such as silk screen glue, silk screen ink, and shoe material adhesive. In order to achieve a beautiful effect, the cold gel is scraped on the fixed rivet using a silk screen to make the glue adhere to and enter the loop of the knitted yarn coil. After the cold gel is scraped, it is cured for about 1-3 hours according to the temperature and humidity. After curing, holes are opened and rivets are hit to achieve a firm effect. Example

[0037] The fastening adhesive layer 3 is a thermosetting adhesive layer. Thermosetting adhesives include silicone, thermosetting ink and other adhesives that cure after heating. In order to achieve a beautiful effect, a silk screen is used to scrape the thermosetting adhesive on the fixed rivets, so that the adhesive adheres to and enters the loop of the knitted fabric yarn coil. It can be cured after being passed through high-temperature equipment such as an oven, a hot air gun, and a pressing machine. After curing, holes are opened and rivets are struck to achieve a firm effect.

[0038] When installing the rivet, the rivet handle 2 is inserted into the opening of the knitted fabric, the rivet column 5 is inserted into the inner cavity of the rivet handle 2, and then the rivet head 1 is hit. The rivet head 1 will transfer the pressure to the rivet handle 2, thereby squeezing the rivet column 5, thereby driving the locking ring 6 to move upward to the top of the locking ring 7, locking the rivet column 5, and the rivet tail 81 will also move accordingly to be in close contact with the surface of the knitted fabric, and cooperate with the rivet head 1 to limit the rivet as a whole, so that the rivet is not easy to fall off from the surface of the knitted fabric when shaking, thereby improving the firmness of the rivet.

[0039] See also Figure 2 , a mounting ring 9 is mounted at the bottom of the rivet head 1, see Figure 4 A limiting plug 10 is installed at the top of the rivet shank 2, and the limiting plug 10 is embedded in the inner cavity of the mounting ring 9. When the rivet head 1 and the rivet shank 2 need to be connected, the limiting plug 10 only needs to be embedded in the mounting ring 9 to connect the rivet head 1 and the rivet shank 2, so that the rivet head 1 and the rivet shank 2 become separate individuals, which is convenient for separate processing of the rivet head 1 and the rivet shank 2.

[0040] See also Figure 3 A non-slip pad layer 11 is installed on the surface of the rivet column 5. The diameter of the non-slip pad layer 11 is consistent with the diameter of the plug-in slot 4. The non-slip pad layer 11 is made of rubber material. After the rivet column 5 is inserted into the plug-in slot 4, the non-slip pad layer 11 will contact the inner wall of the plug-in slot 4, increasing the friction between the rivet column 5 and the plug-in slot 4.

[0041] The surface of the anti-skid pad layer 11 is uniformly provided with anti-skid grooves 12, see Figure 4 The inner wall of the rivet handle 2 is evenly provided with anti-skid patterns 13 , and the anti-skid grooves 12 will also contact with the anti-skid patterns 13 , thereby effectively preventing the rivet column 5 from falling off from the insertion groove 4 .

[0042] See also Figure 5 The lock ring 6 and the lock ring 7 are both annular in design. The surface of the lock ring 6 is inclined in design, and the bottom of the lock ring 6 is flat in design. Please refer to Figure 6 The upper surface of the locking ring 7 is designed to be flat, and the bottom of the locking ring 7 is designed to be inclined, so that the locking ring 6 will contact the inclined surface of the locking ring 7 when moving upward, and the locking ring 6 will easily move to the top of the locking ring 7. The upper surface of the locking ring 7 is designed to be flat, so that the locking ring 6 is not easy to fall off from the surface of the locking ring 7.

[0043] See also Figure 8 The rivet rod 8 and the rivet tail 81 are both hollow in design, and a mounting hole 14 is provided in the middle of the upper surface of the fastening adhesive layer 3. Figure 7 The rivet handle 2 is inserted into the inner cavity of the mounting hole 14. When the rivet rod 8 is subjected to pressure, it will transfer the pressure to the rivet tail 81, so that the rivet tail 81 is deformed completely upward, so that it can be in close contact with the surface of the knitted fabric, thereby reinforcing the rivet.

[0044] This solution is applicable to all processes that use adhesives to bond the openings of knitted fabrics through a hot melt process. The installation operation process of the structural parts of this solution involves bonding before and after the openings. The bonding position of the fastening adhesive layer 3 of this solution can be on the surface of the knitted fabric or on the bottom of the fabric, specifically:

[0045] When the device is working, first the fastening adhesive layer 3 is cut and placed on the knitted fabric where the rivets are installed, and then it is heated by a heating device such as an iron or by scraping and curing it first, so that the fastening adhesive layer 3 is melted and compounded on the surface of the knitted fabric, and then the knitted fabric is opened;

[0046] When opening a hole, the installation rivet is struck so that the rivet can be more firmly installed on the surface of the knitted fabric;

[0047] Since the knitted fabric yarns have been bonded by the melted fastening adhesive layer 3, the holes will not be enlarged due to the pulling of the fabric;

[0048] In this solution, the fastening adhesive layer 3 is melted and fixedly bonded to the opening of the rivet by processing with a heating device such as an iron or by scraping and curing first. The yarns of the knitted fabric that are easy to be demyelinated will be adhered by the fastening adhesive layer 3, so that the loop stem and extension line at the opening of the knitted fabric will not be further expanded due to pulling. After the rivet is punched, the fastening adhesive layer 3 will be hidden in the rivet, and the fastening adhesive layer 3 will not be exposed outside the rivet, thereby improving the aesthetics of the rivet.

[0049] The fastening adhesive layer 3 can be compounded on the surface of the fabric or on the bottom of the fabric, and can be applied to different installation positions of the rivet;

[0050] The traditional solution for installing rivet structures on knitted fabrics is a structure of base + fabric + rivets. To improve the firmness of the connection, there is also a solution of base + plastic gasket + fabric + rivets. However, since the plastic gasket and the fabric are movably connected and cannot be fixed, this method has limited improvement on the rivet fixing performance, and the hard plastic gasket will be exposed outside the rivet structure, which is not beautiful enough.

[0051] This solution adopts the method of base + fastening rubber layer 3 + fabric (+ fastening rubber layer 3) + rivet, and the cut fastening rubber layer 3 is placed on the opening for installing the rivet, and is heated with a heating device such as an iron or a method of first scraping and then curing is adopted, so that the fastening rubber layer 3 is compound-bonded to the knitting yarn to prevent the yarn from demyelination. Since the fastening rubber layer 3 and the knitting yarn are tightly bonded, the connection is more reliable than the traditional solution, and after the rivet is punched, the fastening rubber layer 3 will be hidden in the rivet, and the fastening rubber layer 3 will not be exposed outside the rivet, which is more beautiful.

[0052] When installing the rivet, the rivet handle 2 is inserted into the opening of the knitted fabric, the rivet column 5 is inserted into the inner cavity of the rivet handle 2, and then the rivet head 1 is hit. The rivet head 1 will transfer the pressure to the rivet handle 2, thereby squeezing the rivet column 5, thereby driving the locking ring 6 to move upward to the top of the locking ring 7, and locking the rivet column 5. When the rivet rod 8 is subjected to pressure, it will transfer the pressure to the rivet tail 81, so that the rivet tail 81 is deformed upward, so that it can be in close contact with the surface of the knitted fabric, and the rivet is reinforced, so that the rivet is not easy to fall off from the surface of the knitted fabric when it shakes, thereby improving the firmness of the rivet.

[0053] At the same time, the reinforcement treatment of the knitted fabric by the fastening adhesive layer 3 of the present solution is applicable to all rivet types, including screw type, extrusion type, etc., and is not limited to the rivet structure type exemplified in the present solution.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
