Description

Technical Field

[0001] This invention relates to the field of recorder technology, and in particular to a U-shaped tape for recorders, a U-shaped tape forming process for forming U-shaped tapes for recorders, and a connection structure between the U-shaped tape and the housing. Background Technology

[0002] Voice recorders and other recording devices are widely used, but in current technology, they typically consist of a single main unit. The battery, PCBA circuit board, microphone, and other modules are all housed within this single unit, with wearable components installed outside. This single-unit design usually presents the following problems: 1) The wearable components are inconvenient to attach to a user's belt or pocket; 2) The concentrated placement of the battery and PCBA circuit board leads to poor heat dissipation and difficulty in sealing the battery module; 3) It fails to meet consumer demand for a separate, modular recording device.

[0003] In view of this, the applicant has developed a split-type recorder, comprising two independent main bodies: a recorder function box and a recorder battery box. The recorder function box houses functional modules such as a PCBA circuit board, microphone, and buttons, while the recorder battery box houses the battery. The recorder function box and the recorder battery box are connected via a wearable cable. The advantages of this split-type recorder are: 1) It can be attached to the user's belt or pocket via the wearable cable connecting the recorder function box and the recorder battery box; 2) The separate installation of the battery and PCBA circuit board in the two independent main bodies allows for better heat dissipation control and a better sealing of the battery module; 3) It meets consumer demand for split-type recorder products.

[0004] However, the wearable cable for this type of split recorder currently has the following technical problems: 1) When the wearable cable is attached to the user's belt or pocket, it is easy to slip off due to instability; 2) The wearable cable cannot be used to install the antenna FPC flexible circuit board; 3) The wearable cable has poor overall flexibility and feels stiff; 4) The connection between the wearable cable and the recorder function box and the recorder battery box is not stable enough, and after long-term bending of the wearable cable, the connection between the wearable cable and the recorder function box and the recorder battery box is prone to breakage. Summary of the Invention

[0005] The technical problem this invention aims to solve is to address the shortcomings of the existing technology by providing a U-shaped tape for a recorder. This includes a U-shaped tape molding process and a connection structure between the U-shaped tape and the housing. The recorder U-shaped tape can be securely attached to a user's belt or pocket opening, can accommodate an antenna FPC flexible board, and exhibits good overall flexibility and a soft feel. The recorder U-shaped tape has a first and a second inner plastic module connected to the recorder function box and the recorder battery box. The connection between the recorder U-shaped tape and the recorder function box and battery box is stable, ensuring stable recording even after prolonged bending of the wearable cable. The connection between the U-shaped tape and the recorder's functional box and battery box is less prone to loosening and breakage. The U-shaped tape is manufactured using a layered silicone molding process. After the inner silicone skin of the U-shaped tape is molded, it positions the first inner plastic module, the second inner plastic module, the power cord, and the antenna FPC flexible board. When the liquid silicone base material and curing agent mixture is injected into the outer silicone skin of the U-shaped tape and pressure is maintained, the first inner plastic module, the second inner plastic module, the power cord, and the antenna FPC flexible board are less likely to shift, ensuring a high molding yield for the recorder's U-shaped tape.

[0006] To solve the above-mentioned technical problems, the first technical solution of the present invention is: a U-shaped tape for a recorder, comprising a U-shaped silicone inner sheath, a U-shaped silicone outer sheath, a first plastic inner module, a second plastic inner module, a power cord, and an antenna FPC flexible board. One end of the power cord and the antenna FPC flexible board respectively passes through the first plastic inner module, and the other end of the power cord and the antenna FPC flexible board respectively passes through the second plastic inner module. The U-shaped silicone inner sheath simultaneously covers the inner sides of the first plastic inner module, the second plastic inner module, the power cord, and the antenna FPC flexible board, and the U-shaped silicone outer sheath simultaneously covers the outer sides of the first plastic inner module, the second plastic inner module, the power cord, and the antenna FPC flexible board. The U-shaped silicone inner sheath and the U-shaped silicone outer sheath are integrally formed and connected in a mold.

[0007] The technical effects of the first technical solution of the present invention are as follows: 1) The U-shaped tape of the recorder of the present invention is formed by molding and connecting the U-shaped silicone inner skin and the U-shaped silicone outer skin in the mold. After the U-shaped silicone inner skin and the U-shaped silicone outer skin are connected, they form a thin U-shaped structure, which can be stably hung on the user's belt or pocket; 2) The U-shaped tape of the recorder of the present invention has an antenna FPC flexible board installed inside, so that the recorder body (e.g., recorder function box, recorder battery box) of the recorder U-shaped tape does not need to be installed with an antenna FPC flexible board separately; 3) The U-shaped silicone inner skin and the U-shaped silicone outer skin of the recorder U-shaped tape of the present invention are both made of silicone material, which has good overall softness and a soft feel; 4) The two ends of the U-shaped tape of the recorder of the present invention are provided with a first plastic inner module and a second plastic inner module, which can achieve a stable connection with the recorder body (e.g., recorder function box, recorder battery box) of the recorder U-shaped tape, and avoid the problem of breakage at the connection between the recorder U-shaped tape and the recorder body after long-term use.

[0008] In the above technical solution, the U-shaped silicone inner skin and the U-shaped silicone outer skin are respectively provided with a power line groove for positioning the power line, an FPC groove for positioning the antenna FPC flexible board, a first inner module groove for positioning the first plastic inner module, and a second inner module groove for positioning the second plastic inner module. This structure enables the U-shaped silicone inner skin and the U-shaped silicone outer skin to stably position the first plastic inner module, the second plastic inner module, the power line, and the antenna FPC flexible board, and can avoid displacement problems during the molding of the U-shaped silicone outer skin.

[0009] To solve the above-mentioned technical problems, the second technical solution of the present invention is: a U-shaped tape forming process, specifically used for forming the aforementioned U-shaped tape for recorders, comprising the following forming process steps: S1. Prepare a silicone tape molding die, which has a first cavity and a second cavity; S2. After mixing the liquid silicone base material with the curing agent, inject it into the first cavity of the silicone tape molding mold. At the set molding temperature, perform the first in-mold molding to form a U-shaped silicone inner skin. The U-shaped silicone inner skin is provided with a power line groove for positioning the power line, an FPC groove for positioning the antenna FPC flexible board, a first inner module groove for positioning the first plastic inner module, and a second inner module groove for positioning the second plastic inner module. S3. Insert the power cord into the U-shaped power cord slot with silicone inner sheath, insert the antenna FPC flexible board into the U-shaped FPC slot with silicone inner sheath, insert the first plastic inner module into the first inner module slot with silicone inner sheath, and insert the second plastic inner module into the second inner module slot with silicone inner sheath. S4. Place the assembled U-shaped silicone inner skin, first plastic inner module, second plastic inner module, power cord and antenna FPC flexible board together into the second cavity of the silicone strip molding mold. S5. After mixing the liquid silicone base material with the curing agent, inject it into the second cavity of the silicone tape molding mold. At the set molding temperature, perform a second in-mold molding to form a U-shaped silicone outer skin. The U-shaped silicone inner skin and the U-shaped silicone outer skin are molded together in the mold and connected as one piece. The U-shaped silicone outer skin and the U-shaped silicone inner skin together tightly cover the first plastic inner module, the second plastic inner module, the power cord and the antenna FPC flexible board.

[0010] The technical effect of the second technical solution of the present invention is as follows: After the U-shaped silicone inner skin is formed, the U-shaped silicone inner skin has a built-in power line groove, FPC groove, first inner module groove and second inner module groove. At this time, the power line, antenna FPC flexible board, first plastic inner module and second plastic inner module can be positioned by the U-shaped silicone inner skin. When the liquid silicone base material and curing agent mixture for forming the U-shaped silicone outer skin is injected into the second mold cavity and pressure is maintained, the power line, antenna FPC flexible board, first plastic inner module and second plastic inner module are less likely to shift. This avoids the problems of eccentricity and popping of the power line and antenna FPC flexible board caused by internal material accumulation or injection pressure during in-mold molding production, ensuring that the U-shaped tape of the recorder has a high molding yield and ensuring that the power line and antenna FPC flexible board meet the reliability function and electrical performance test requirements.

[0011] In the above technical solution, the first cavity of the silicone tape molding mold has a first U-shaped cavity for molding a U-shaped silicone inner skin, and the second cavity of the silicone tape molding mold has a second U-shaped cavity for molding a U-shaped silicone outer skin. The first U-shaped cavity of this invention can mold a U-shaped silicone inner skin, and the second U-shaped cavity can mold a U-shaped silicone outer skin, thus forming the U-shaped silicone inner skin and the U-shaped silicone outer skin together as a single unit within the second U-shaped cavity.

[0012] In the above technical solution, a positioning fixture is provided within the second cavity of the silicone strip molding mold. In step S4, the positioning fixture positions the U-shaped silicone inner skin. In steps S2 and S5, the molding temperature is 118℃-122℃. The positioning fixture of the present invention indirectly positions the power line, antenna FPC flexible board, first plastic inner module, and second plastic inner module by positioning the U-shaped silicone inner skin, ensuring that the U-shaped silicone outer skin can be reliably molded. The present invention sets the molding temperature to 118℃-122℃, preferably 120℃, which enables the U-shaped silicone inner skin and the U-shaped silicone outer skin to reach the optimal molding temperature, and allows the U-shaped silicone inner skin and the U-shaped silicone outer skin to be molded and connected as one piece within the second U-shaped cavity at a molding temperature of 118℃-122℃.

[0013] To solve the above-mentioned technical problems, the third technical solution of the present invention is: a U-shaped tape and a box body connection structure, including the aforementioned recorder U-shaped tape, recorder function box and recorder battery box, wherein one end of the recorder function box is provided with a function box connecting part, and one end of the recorder U-shaped tape is fixedly connected to the function box connecting part; one end of the recorder battery box is provided with a battery box connecting part, and the other end of the recorder U-shaped tape is fixedly connected to the battery box connecting part.

[0014] The technical effect of the third technical solution of the present invention is that the third technical solution of the present invention has all the technical effects of the first technical solution. Furthermore, since the two ends of the U-shaped tape of the recorder are provided with a first plastic inner module and a second plastic inner module, one end of the U-shaped tape of the recorder can be fixedly connected to the function box connecting part of the recorder function box through the first plastic inner module, and the other end of the U-shaped tape of the recorder can be fixedly connected to the battery box connecting part of the recorder battery box through the second plastic inner module. This makes the connection between the U-shaped tape of the recorder and the recorder function box and the recorder battery box stable. After long-term bending of the wearable cable, the connection between the U-shaped tape of the recorder and the recorder function box and the recorder battery box is not prone to loosening or breakage.

[0015] In the above technical solution, the functional box connecting part includes a first U-shaped belt end receiving groove, a first inner module insertion cavity, a pin, and a first screw. The first U-shaped belt end receiving groove is disposed on the outer side of one end of the recorder functional box, and the shape of the first U-shaped belt end receiving groove is adapted to the shape of one end of the U-shaped belt silicone inner skin and the U-shaped belt silicone outer skin. One end of the recorder U-shaped belt is received within the first U-shaped belt end receiving groove. The first inner module insertion cavity penetrates the bottom of the first U-shaped belt end receiving groove. The first plastic inner module is provided with a first inner module connecting part, which passes through the first inner module insertion cavity. The inner end of the first inner module insertion cavity is provided with a first pin hole, and the first inner module connecting part is provided with a second pin hole. The pin is inserted into the first pin hole and the second pin hole. The bottom of the first U-shaped belt end receiving groove is also provided with a first connecting hole, and the first screw passes through the first connecting hole and is screwed and locked to the first plastic inner module. The preferred technical solution has the following technical effects: 1) Since a first U-shaped tape end receiving groove is provided on the outer side of one end of the recorder function box, and the shape of the first U-shaped tape end receiving groove is adapted to the shape of one end of the U-shaped tape silicone inner skin and the U-shaped tape silicone outer skin, one end of the recorder U-shaped tape is received in the first U-shaped tape end receiving groove. Therefore, one end of the recorder U-shaped tape can be initially limited and positioned by the first U-shaped tape end receiving groove, and one end of the U-shaped tape silicone inner skin and the U-shaped tape silicone outer skin can be hidden in the first U-shaped tape end receiving groove, avoiding the U-shaped tape silicone inner skin and the U-shaped tape silicone outer skin from being separated. 1) One end of the tape is exposed, which provides a good visual effect; 2) One end of the U-shaped tape of the recorder can be fixed by interlocking the first inner module connecting part of the first plastic inner module with the first inner module insertion cavity of the function box connecting part. The pin can prevent the first inner module connecting part from being pulled outward, and the first screw can further screw and lock the first inner module connecting part. Under the triple fixing effect of the first inner module insertion cavity, the pin and the first screw, the connection between one end of the U-shaped tape of the recorder and the function box of the recorder is very stable, and the connection between the U-shaped tape of the recorder and the function box of the recorder is not prone to loosening or breakage.

[0016] In the above technical solution, two sets of the first connecting holes and first screws are provided, respectively located on both sides of the first inner module connecting part. One end of the power cord and the antenna FPC flexible board both extend into the recorder function box. The recorder function box includes a function box body and a function box cover that fit together, and the function box connecting part is located at one end of the function box body. This invention uses two first screws to screw and lock the first inner module connecting part from both sides, which can optimally fix the first plastic inner module.

[0017] In the above technical solution, the battery box connecting part includes a second U-shaped belt end receiving groove, a second inner module insertion cavity, a connecting seat, and a second screw. The second U-shaped belt end receiving groove is located on the outer side of one end of the recorder battery box, and the shape of the second U-shaped belt end receiving groove is adapted to the shape of the other end of the U-shaped belt silicone inner skin and the U-shaped belt silicone outer skin. The other end of the recorder U-shaped belt is received within the second U-shaped belt end receiving groove. The second inner module insertion cavity penetrates the bottom of the second U-shaped belt end receiving groove. The second plastic inner module is provided with a second inner module connecting part, which passes through the second inner module insertion cavity. The end of the second inner module connecting part is provided with a second connecting hole. The connecting seat is located inside the recorder battery box, and a screw hole is provided on the connecting seat. After the second screw passes through the second connecting hole, it is screwed and locked with the screw hole of the connecting seat. The preferred technical solution has the following technical effects: 1) Because a second U-shaped tape end receiving groove is provided on the outer side of one end of the recorder battery box, and the shape of the second U-shaped tape end receiving groove is adapted to the shape of the other end of the U-shaped tape silicone inner skin and the U-shaped tape silicone outer skin, the other end of the recorder U-shaped tape is received within the second U-shaped tape end receiving groove. Therefore, the other end of the recorder U-shaped tape can be initially limited and positioned by the second U-shaped tape end receiving groove, and the other end of the U-shaped tape silicone inner skin and the U-shaped tape silicone outer skin can be hidden within the second U-shaped tape end receiving groove, avoiding U-shaped tape end receiving groove end confinement. 1) The other ends of the silicone inner skin of the U-shaped tape and the silicone outer skin of the U-shaped tape are exposed, resulting in a good visual effect; 2) The other end of the U-shaped tape of the recorder can be connected and fixed to the battery box by the second inner module connecting part of the second plastic inner module and the second inner module insertion cavity of the battery box connecting part. The second screw can further screw and lock the second inner module connecting part. Under the dual fixing effect of the second inner module insertion cavity and the second screw, the other end of the recorder U-shaped tape can be connected to the recorder battery box very stably, and the connection between the recorder U-shaped tape and the recorder battery box is not prone to loosening or breakage.

[0018] In the above technical solution, the number of the second inner module insertion cavity, the second inner module connecting part, the second connecting hole, the connecting seat, the screw hole, and the second screw are all two. The battery box connecting part also includes a metal plate, and each end of the metal plate is provided with a third connecting hole corresponding to the second connecting hole. The second screw passes through the third connecting hole and the second connecting hole in sequence, and then is screwed and locked to the screw hole of the connecting seat. The metal plate is provided with a positioning hole in the middle, and a positioning post is provided inside the recorder battery box. The positioning post passes through the positioning hole of the metal plate. The recorder battery box includes a battery box body and a battery box cover that cover each other. The battery box connecting part is located at one end of the battery box body. This invention uses two second screws to screw and lock two parallel second inner module connecting parts, and further fixes the two parallel second inner module connecting parts with the metal plate and the positioning post, which can optimally fix the second plastic inner module.

[0028] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0029] like Figures 1-3 As shown, Embodiment 1 provides a U-shaped tape 100 for a recorder, including a U-shaped silicone inner sheath 1, a U-shaped silicone outer sheath 2, a first plastic inner module 3, a second plastic inner module 4, a power cord 5, and an antenna FPC flexible board 6. One end of the power cord 5 and the antenna FPC flexible board 6 respectively passes through the first plastic inner module 3, and the other end of the power cord 5 and the antenna FPC flexible board 6 respectively passes through the second plastic inner module 4. The U-shaped silicone inner sheath 1 simultaneously covers the inner sides of the first plastic inner module 3, the second plastic inner module 4, the power cord 5, and the antenna FPC flexible board 6, and the U-shaped silicone outer sheath 2 simultaneously covers the outer sides of the first plastic inner module 3, the second plastic inner module 4, the power cord 5, and the antenna FPC flexible board 6. The U-shaped silicone inner sheath 1 and the U-shaped silicone outer sheath 2 are integrally formed in a mold.

[0030] The U-shaped tape 100 of this invention uses a U-shaped silicone inner skin 1 and a U-shaped silicone outer skin 2, which are molded and connected as one piece. After being connected, the U-shaped silicone inner skin 1 and the U-shaped silicone outer skin 2 form a thin U-shaped structure, which can be securely hung on the user's belt or pocket. An antenna FPC flexible board 6 is installed inside the U-shaped tape 100, so that the recorder body (e.g., recorder function box, recorder battery box) does not need to be separately installed with the recorder body (e.g., recorder function box, recorder battery box). C-type flexible board 6; The U-shaped silicone inner skin 1 and the U-shaped silicone outer skin 2 of the U-shaped tape 100 of the recorder of the present invention are both made of silicone material, which has good overall softness and a soft feel; The two ends of the U-shaped tape 100 of the recorder of the present invention are provided with a first plastic inner module 3 and a second plastic inner module 4, which can achieve a stable connection with the recorder body (such as the recorder function box, the recorder battery box) of the U-shaped tape 100 of the recorder, and avoid the problem of breakage at the connection between the U-shaped tape 100 and the recorder body after long-term use.

[0031] like Figures 2-3 As shown, the U-shaped silicone inner sheath 1 and the U-shaped silicone outer sheath 2 are respectively provided with a power cable groove 11 for positioning the power cable 5, an FPC groove 12 for positioning the antenna FPC flexible board 6, a first inner module groove 13 for positioning the first plastic inner module 3, and a second inner module groove 14 for positioning the second plastic inner module 4 on opposite sides. This structure enables the U-shaped silicone inner sheath 1 and the U-shaped silicone outer sheath 2 to stably position the first plastic inner module 3, the second plastic inner module 4, the power cable 5, and the antenna FPC flexible board 6, and can avoid displacement problems during the molding of the U-shaped silicone outer sheath 2. Example 2

[0032] Example 2 provides a U-shaped strip forming process, in conjunction with reference. Figures 1-3 The molding process specifically for the U-shaped tape 100 of the recorder described in Embodiment 1 includes the following molding steps: S1. Prepare a silicone tape molding die, which has a first cavity and a second cavity; S2. After mixing the liquid silicone base material with the curing agent, the mixture is injected into the first cavity of the silicone tape molding mold. At the set molding temperature, the first in-mold molding is performed to form a U-shaped silicone inner skin 1. The U-shaped silicone inner skin 1 is provided with a power line groove 11 for positioning the power line 5, an FPC groove 12 for positioning the antenna FPC flexible board 6, a first inner module groove 13 for positioning the first plastic inner module 3, and a second inner module groove 14 for positioning the second plastic inner module 4. S3. Insert the power cord 5 into the power cord slot 11 of the U-shaped silicone inner sheath 1, insert the antenna FPC flexible board 6 into the FPC slot 12 of the U-shaped silicone inner sheath 1, insert the first plastic inner module 3 into the first inner module slot 13 of the U-shaped silicone inner sheath 1, and insert the second plastic inner module 4 into the second inner module slot 14 of the U-shaped silicone inner sheath 1. S4. Place the assembled U-shaped silicone inner skin 1, first plastic inner module 3, second plastic inner module 4, power cord 5 and antenna FPC flexible board 6 together into the second cavity of the silicone strip molding mold. S5. After mixing the liquid silicone base material with the curing agent, inject it into the second cavity of the silicone tape molding mold. At the set molding temperature, perform a second in-mold molding to form a U-shaped silicone outer skin 2. The U-shaped silicone inner skin 1 and the U-shaped silicone outer skin 2 are connected together in the in-mold molding. The U-shaped silicone outer skin 2 and the U-shaped silicone inner skin 1 together tightly cover the first plastic inner module 3, the second plastic inner module 4, the power cord 5, and the antenna FPC flexible board 6.

[0033] After the U-shaped silicone inner skin 1 is formed, the U-shaped silicone inner skin 1 has a built-in power cable groove 11, FPC groove 12, first inner module groove 13, and second inner module groove 14. At this time, the power cable 5, antenna FPC flexible board 6, first plastic inner module 3, and second plastic inner module 4 can be positioned by the U-shaped silicone inner skin 1. When the liquid silicone base material and curing agent mixture of the U-shaped silicone outer skin 2 is injected into the second mold cavity and pressure is maintained, the power cable 5, antenna FPC flexible board 6, first plastic inner module 3, and second plastic inner module 4 are less likely to shift. This avoids the problems of eccentricity and popping of the power cable 5 and antenna FPC flexible board 6 caused by internal material accumulation or injection pressure during in-mold molding production, ensuring that the recorder U-shaped tape 100 has a high molding yield and that the power cable 5 and antenna FPC flexible board 6 meet the reliability function and electrical performance test requirements.

[0034] In a preferred embodiment of the present invention, the first cavity of the silicone tape molding mold has a first U-shaped cavity for molding a U-shaped silicone inner skin 1, and the second cavity of the silicone tape molding mold has a second U-shaped cavity for molding a U-shaped silicone outer skin 2. The first U-shaped cavity of the present invention can mold the U-shaped silicone inner skin 1, and the second U-shaped cavity can mold the U-shaped silicone outer skin 2, thereby forming the U-shaped silicone inner skin 1 and the U-shaped silicone outer skin 2 integrally within the second U-shaped cavity.

[0035] In a preferred embodiment of the present invention, a positioning fixture is provided within the second cavity of the silicone strip molding mold. In step S4, the positioning fixture positions the U-shaped silicone inner skin 1. In steps S2 and S5, the molding temperature is 118℃-122℃. The positioning fixture of the present invention indirectly positions the power line 5, the antenna FPC flexible board 6, the first plastic inner module 3, and the second plastic inner module 4 by positioning the U-shaped silicone inner skin 1, ensuring that the U-shaped silicone outer skin 2 can be reliably molded. The present invention sets the molding temperature to 118℃-122℃, preferably 120℃, which enables the U-shaped silicone inner skin 1 and the U-shaped silicone outer skin 2 to reach the optimal molding temperature, and allows the U-shaped silicone inner skin 1 and the U-shaped silicone outer skin 2 to be molded and connected as one piece within the second U-shaped cavity at a molding temperature of 118℃-122℃. Example 3

[0036] like Figures 4-9 As shown, in conjunction with reference Figures 1-3 Embodiment 3 provides a U-shaped strap and housing connection structure, including the aforementioned recorder U-shaped strap 100, recorder function box 200, and recorder battery box 300. One end of the recorder function box 200 is provided with a function box connecting part, and one end of the recorder U-shaped strap 100 is fixedly connected to the function box connecting part; one end of the recorder battery box 300 is provided with a battery box connecting part, and the other end of the recorder U-shaped strap 100 is fixedly connected to the battery box connecting part. Embodiment 3 of the present invention possesses all the technical effects of Embodiment 1. Furthermore, since the two ends of the recorder U-shaped strap 100 are provided with a first plastic inner module 3 and a second plastic inner module 4, one end of the recorder U-shaped strap 100 can be fixedly connected to the function box connecting part of the recorder function box 200 through the first plastic inner module 3, and the other end of the recorder U-shaped strap 100 can be fixedly connected to the battery box connecting part of the recorder battery box 300 through the second plastic inner module 4. This makes the connection between the recorder U-shaped strap 100 and the recorder function box 200 and the recorder battery box 300 stable. After long-term bending of the wearable cable, the connection between the recorder U-shaped strap 100 and the recorder function box 200 and the recorder battery box 300 is less likely to loosen or break.

[0037] like Figure 5 , Figure 7 and Figure 8 As shown, the functional box connecting part includes a first U-shaped belt end receiving groove 201, a first inner module insertion cavity 202, a pin 203, and a first screw 204. The first U-shaped belt end receiving groove 201 is disposed on the outer side of one end of the recorder functional box 200, and the shape of the first U-shaped belt end receiving groove 201 is adapted to the shape of one end of the U-shaped belt silicone inner skin 1 and the U-shaped belt silicone outer skin 2. One end of the recorder U-shaped belt 100 is received within the first U-shaped belt end receiving groove 201; the first inner module insertion cavity 202 penetrates the first U-shaped belt end receiving groove 201.
