Sliding rail type socket belt applicable to clothing

Abstract

The sliding rail type socket belt applicable to clothing comprises a female thread belt and a male thread belt; characterized in that, the female thread belt is a soft profile body extending along the axial direction. From the cross-section view, the female thread belt includes a female thread belt handle and a female thread belt groove body integrally formed together. The Shore hardness of the female thread belt groove body is 70-120A, and the Shore hardness of the female thread belt handle is not greater than that of the female thread belt groove body. The female thread belt groove body has a cavity in a drawstring shape. The female thread belt handle is used for connecting the fabric. The male thread belt is in a T shape and includes a male thread belt head and a male thread belt handle. The male thread belt head can be axially slidably installed into the cavity, and the male thread belt handle extends out from the notch of the cavity. The male thread belt handle is used for connecting the fabric. Since the female thread belt with a relatively long axial extension length has ideal softness, when applied to clothing, it can well match the softness of the clothing fabric and will not form an obvious rigid belt strip on the clothing, seriously damaging the wearing experience of the clothing.

Description

Technical Field

[0001] The present invention relates to a connecting fitting for clothing, and particularly to a slide rail type socket belt applicable to clothing. The slide rail type socket belt can be used for detachably connecting two clothing parts. Background Art

[0002] Today, there are various types of zipper teeth for clothing. The more common ones are snap-type hard teeth, including: synthetic resin teeth in the shape of granules, which are directly formed on the side edge of the tape by an injection molding process and are arranged at intervals along the axial direction; or metal teeth in the shape of granules, which are Y-shaped in cross-section and have upper and lower clamping feet. The metal teeth are clamped on the side edge of the tape by the upper and lower clamping feet and are arranged at intervals along the axial direction. When the zippers with the above two types of teeth are in the closed state, the teeth on the two tapes are interlocked left and right, and there are obvious gaps between the axially adjacent teeth.

[0003] In addition, a sliding chain has emerged on the market. For example, a safety sliding chain proposed in CN201410658506.1 includes an upper chain body and a lower chain body. The upper chain body includes a plurality of clamping rings arranged on a base fabric at axial intervals. Each clamping ring includes two arc-shaped clamping arms connected as a whole. The lower chain body includes a long chute and a base fabric connecting seat arranged at the lower end of the chute. The base fabric connecting seat is connected to the base fabric. The upper chain body is connected to the lower chain body by clamping the chute with the clamping rings. Or, the invention patent application with the patent number CN201811419372.2 proposed by the inventor on November 26, 2018 discloses an asymmetric light sliding zipper, which includes a first chain tape and a second chain tape arranged left and right and extending axially respectively. On the inner side of the first chain tape, female chain teeth arranged at axial intervals are provided. Each female chain tooth includes a female tooth head and a female tooth tail arranged left and right. The female tooth tail is connected to the first chain tape, and the female tooth head extends from the female tooth tail to form an open ring, thus having a female chain tooth groove and a female chain tooth groove opening. The female chain tooth grooves of several adjacent female chain teeth arranged at front and rear intervals form an axially extending receiving groove channel. On the inner side of the second chain tape, male chain tooth heads extending axially and capable of being received in the female chain tooth grooves are provided. The height of the male chain tooth head is greater than the height of the female chain tooth groove opening and less than the height of the female chain tooth groove. When the male chain tooth head is inserted into the female chain tooth groove, the male chain tooth head can axially slide in the receiving groove channel. It is characterized in that, seen from the cross-section, the horizontal center line of the female chain tooth groove of the female tooth head is displaced relative to the horizontal center line of the female tooth tail. It can be found that the clamping rings in patent CN201410658506.1 and the female chain teeth in patent CN201811419372.2 are also substantially granular. When the chain tapes are combined together, obvious gaps also remain between adjacent clamping rings and female chain teeth. Summary of the Invention

[0004] Through the analysis of the above-mentioned prior art, it can be found that the axial interval arrangement of the chain teeth on the same chain tape can reduce the adverse impact of the arrangement of the chain teeth on the flexibility of the chain tape. However, the subsequent problem is that the gaps between the chain teeth damage the overall appearance integrity of the whole chain tape and the airtightness of the chain tape. To solve the above problems, a common solution is to sew a covering cloth on the chain tape on the finished clothing, but this method does not fundamentally solve the above-mentioned defects existing in the chain tape itself.

[0005] In view of the shortcomings of the prior art, one of the inventive objectives of the present invention is to propose a novel connecting belt that is not only applicable to soft items such as clothing, but also has ideal sealing properties. In order to achieve the above objectives, the present invention proposes a sliding rail type sleeve belt suitable for clothing, comprising a female tooth belt and a male tooth belt; the female tooth belt is a soft profile body and extends axially. From a cross-section, the female tooth belt comprises a female tooth belt handle and a female tooth belt groove body that are integrally formed together. The Shore hardness of the female tooth belt groove body is 70-120A, and the Shore hardness of the female tooth belt handle is not greater than the Shore hardness of the female tooth belt groove body. The female tooth belt groove body has a groove cavity in the shape of a bundle. The female tooth belt handle is used to connect cloth-like objects. The male tooth belt is T-shaped and includes a male tooth belt head and a male tooth belt handle. The male tooth belt head can be axially slidably installed in the groove cavity. The male tooth belt handle extends from the notch of the groove cavity. The male tooth belt handle is used to connect cloth-like objects.

[0006] Among them, the mother tooth belt is first of all a profile body, that is, the cross-sectional structure and size at each point in the axial direction are basically the same, and it has a certain axial length, such as 0.1 meters, 0.3 meters, 0.5 meters, etc. It can also be processed into a mother tooth belt of up to 1 meter, 2 meters or longer at one time, and then cut according to actual application needs. In addition, since the mother tooth belt groove body is a soft part with a Shore hardness of 70 to 120A, the Shore hardness of the mother tooth belt handle is not greater than the Shore hardness of the mother tooth belt groove body, so the structure with an axial extension length basically does not cause a significant adverse effect on the softness of the entire mother tooth belt. Therefore, in terms of structure and softness, the mother tooth belt is obviously different from the clamping ring in patent CN201410658506.1 and the mother chain tooth in patent CN201811419372.2.

[0007] The female tooth band comprises an integrally formed female tooth band handle and female tooth band groove. This feature defines that at least one of the female tooth band handle and female tooth band groove is simultaneously connected to the other during the forming process, thereby forming an integrated structure. In specific applications, injection molding, extrusion molding, casting molding, and other processes can be used to achieve this integrated structure, depending on the structural characteristics of the component. The term "integrated molding" mentioned below has the same meaning as above unless otherwise specified.

[0008] Among them, the groove cavity is in a bundle-mouth shape, so when the male tooth belt head is axially slidably installed in the groove cavity, the male tooth belt head will not easily pass through the groove of the groove cavity and separate from the female tooth belt groove body under the action of the lateral (left and right) pulling force, thereby facilitating the maintenance of an effective sliding connection relationship between the female tooth belt and the male tooth belt.

[0009] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: Since the female tooth belt is a soft profile body and extends axially, and the Shore hardness of the female tooth belt groove body and the female tooth belt handle adopts the above configuration, thus, the female tooth belt with a relatively long axial extension length can still have ideal softness, and when applied to clothing, it can well match the softness of the clothing fabric and will not form obvious rigid belt strips on the clothing, seriously damaging the wearing experience of the clothing; In addition, after the male tooth head is axially slidably installed into the cavity of the female tooth belt groove body, a long strip-shaped sealing area is formed between the female tooth belt and the male tooth belt, effectively reducing the air permeability of the sliding rail type socket belt, improving the waterproof effect, and also being beneficial to optimizing the heat preservation effect inside the clothing; Secondly, since the sliding sleeve structures of the female tooth belt and the male tooth belt do not need the assistance of a pull head, that is, there is no need to reserve a sliding space for the pull head on the female tooth belt handle and the male tooth belt handle, so the fabric can cover the female tooth belt handle and the male tooth belt handle to reduce their exposure, thereby optimizing the concealment effect of the sliding rail type socket belt.

[0010] As for the structural form of the male tooth head, it can be diverse, and one of the following structures can be selected.

[0011] The first structural form of the male tooth head: The male tooth head is a soft profile body with a Shore hardness of 70-120A and extends axially, and the Shore hardness of the male tooth belt handle is not greater than that of the male tooth head. First, the male tooth head is a profile body, that is, the cross-sectional structure and size at each point in the axial direction are basically the same, and it extends axially for a certain length, such as 0.1 m, 0.3 m, 0.5 m, etc. It is also possible to process a male tooth head with a length of up to 1 m, 2 m or longer at one time, and then cut it according to actual application needs. The male tooth head with an axial extension length is beneficial to strengthening the sealing performance after the male tooth head and the female tooth belt groove body sliding sleeve are combined; Secondly, since the Shore hardness of the male tooth head and the male tooth belt handle adopts the above configuration, thus, the structure with an axial extension length basically will not cause obvious adverse effects on the softness of the whole male tooth belt.

[0012] Furthermore, the male tooth head is a TPU, PVC or EVA soft rubber profile body. Among them, TPU is thermoplastic polyurethane elastomer rubber, PVC is polyvinyl chloride, and EVA is ethylene-vinyl acetate copolymer. Through multiple tests and performance evaluations, it is found that TPU is the most suitable material for manufacturing the male tooth head among the above soft rubber materials. The reason is that TPU is an environmentally friendly material, and a large amount of application will not cause environmental pollution, and its temperature resistance is as high as 180°, and it has excellent resistance to bending and aging. It is not easy to be damaged after multiple bendings or in a high-temperature environment, meeting the requirements of daily application and service life of clothing.

[0013] The second male tooth head structure: The male tooth heads are granular, and a plurality of the male tooth heads are axially arranged at intervals on the male tooth belt handle. In this way, the male tooth heads can be injection-molded from hard thermoplastic materials such as PP and PC, and their hardness does not greatly damage the overall softness of the male tooth belt.

[0014] For the male tooth belt proposed by the present invention, the following improved solutions can be further selected: For example, the male tooth head and the male tooth belt handle are integrally formed together, which is beneficial to simplifying the structure of the male tooth belt. Or the transverse width of the male tooth belt handle is 4 to 20 times the transverse width of the male tooth head, so that the male tooth belt handle has sufficient transverse width to facilitate directly sewing the male tooth belt handle onto the clothing. Or the male tooth belt handle is a rubber belt handle, a woven belt handle, or a mixed belt handle of rubber and fabric.

[0015] As for the female tooth belt, the following improved solutions can be further selected: The female tooth belt groove body is a TPU, PVC or EVA soft rubber profile body. Or the transverse width of the female tooth belt handle is 2 to 8 times the transverse width of the female tooth belt groove body, so that the female tooth belt handle has sufficient transverse width to facilitate directly sewing the female tooth belt handle onto the clothing. Or the female tooth belt handle is a rubber belt handle, a woven belt handle, or a mixed belt handle of rubber and fabric.

[0016] In addition, the female tooth belt groove body can be symmetrically arranged up and down with the thickness center line of the female tooth belt handle as the axis of symmetry, and the male tooth head can be symmetrically arranged up and down with the thickness center line of the male tooth belt handle as the axis of symmetry. Or adopt the following layout method: From the cross-section view, the female tooth belt groove body is offset to the lower side of the female tooth belt handle; the male tooth head is offset to the lower side of the male tooth belt handle. In this way, it is beneficial to optimize the concealment of the female tooth belt groove body and the male tooth head.

[0017] In addition, in order to prevent the female thread belt and the male thread belt together with the sliding sleeve from disengaging, the present invention also proposes an upper stop device, and the specific structure is as follows: The sliding rail type socket belt further includes an upper stop device capable of preventing the female thread belt and the male thread belt from disengaging. The upper stop device includes a left stop member and a right stop member that are interchangeably arranged on the female thread belt or the male thread belt; wherein the left stop member includes a left socket, the left socket has a plugging main cavity and a plugging hole that is substantially perpendicular to and penetrates the plugging main cavity, and an axial socket is provided at the head end of the plugging main cavity; the right stop member includes a right plug arm, and the right plug arm includes a main plug arm that can axially pass through the axial socket and be inserted into the plugging main cavity and a secondary plug arm that can be inserted into the plugging hole. In this way, when the main plug arm is plugged and combined with the plugging main cavity, the secondary plug arm can be kept in a plugged and combined state with the plugging hole, thereby increasing the difficulty of axial and transverse (left and right directions) separation of the female thread belt and the male thread belt. However, applying a sufficient large axial pulling force can cause the secondary plug arm to deform and disengage from the plugging hole, thereby axially disengaging the female thread belt and the male thread belt. Among them, the "interchangeability" means that when the left stop member is arranged on the female thread belt, the right stop member is arranged on the male thread belt; or when the left stop member is arranged on the male thread belt, the right stop member is arranged on the female thread belt.

[0018] Further, when viewed in cross-section, the plugging main cavity is in a flared shape and thus includes a main cavity body and a side cavity opening. The main plug arm is in a T shape and includes a plug head and a plug handle. The plug head can be axially inserted into the main cavity body, and the plug handle can extend out from the side cavity opening. In this way, the difficulty of transverse separation of the female thread belt and the male thread belt can be increased.

[0019] Further, the main cavity body of the plugging main cavity is substantially conical, so that the cross-sectional area of the main cavity body gradually decreases from the head end to the tail end. The plug head is adapted to the main cavity body and is also substantially conical and thus has a large end head and a thin end tail. In this way, during the process of axially inserting the plug head into the main cavity body, taking advantage of the fact that the thin end tail is the preferred insertion end and is smaller than the axial socket of the main cavity body, it can be conveniently inserted into the main cavity body, greatly simplifying the plugging operation.

[0020] Further, the side cavity opening of the plugging main cavity includes a first-stage wide opening and a tail-stage narrowing opening that gradually narrows towards the tail end; the plug handle is arranged to match the side cavity opening and includes a first-stage thick wall portion and a tail-stage thin wall portion that gradually narrows towards the tail end, and the first-stage thick wall portion and the first-stage wide opening can be tightly fitted together. In this way, during the process of axially inserting the plug handle into the side cavity opening of the plugging main cavity, taking advantage of the fact that the tail-stage thin wall portion of the plug handle is the preferred insertion end and is smaller than the first-stage wide opening, it can be conveniently inserted into the side cavity opening. In addition, after the first-stage thick wall portion and the first-stage wide opening are tightly fitted together, the difficulty of axial separation of the female thread belt and the male thread belt can be increased.

[0021] Further, when viewed in the depth direction of the insertion hole, the insertion hole is strip-shaped and arranged obliquely relative to the axial direction, and the diameter of the secondary insertion arm is comparable to the width of the insertion hole. In this way, the difficulty of axial separation between the secondary insertion arm and the insertion hole can be increased, and further the difficulty of axial separation between the female tooth belt and the male tooth belt can be increased.

[0022] Further, the left stop member is provided on the female tooth belt, the left socket wraps one end of the groove body of the female tooth belt, and the insertion main cavity of the left socket communicates with the groove cavity of the groove body of the female tooth belt; the right stop member is provided on the male tooth belt, and the right insertion arm wraps one end of the male tooth head. In this way, adopting the above wrapping structure is beneficial to optimizing the integral appearance effect of the slide rail type socket belt.

[0023] Further, the left stop member further includes a left connecting portion, one end of the left connecting portion connects the left socket, and the other end connects one of the female tooth belt handle and the male tooth belt handle. The left socket is separately arranged from the female tooth belt groove body or the male tooth head on the belt strip connected by the left stop member; alternatively / and the right stop member further includes a right connecting portion, one end of the right connecting portion connects the right insertion arm, and the other end connects to the other of the female tooth belt handle and the male tooth belt handle. The right insertion arm is separately arranged from the female tooth belt groove body or the male tooth head on the belt strip connected by the right stop member. In this way, compared with the above wrapping structure, adopting the above separation structure can prevent the left socket from wrapping and flattening the female tooth belt groove body or the right insertion arm from wrapping and flattening the male tooth head, thereby destroying the sliding socket insertion effect of the female tooth belt and the male tooth belt.

[0024] In addition, in order to prevent the female tooth belt and the male tooth belt from disengaging, the present invention also proposes a lower stop device, and the specific structure is as follows: the slide rail type socket belt further includes a lower stop device capable of preventing the female tooth belt and the male tooth belt from disengaging. The lower stop device includes an insertion box assembly and an insertion pin assembly that are interchangeably arranged on the female tooth belt or the male tooth belt. The insertion box assembly includes a box body having a box inner cavity, and the insertion pin assembly includes an insertion pin that can be axially inserted into the box inner cavity. In this way, when the insertion pin is inserted and combined with the box body, the difficulty of lateral (left and right direction) separation between the female tooth belt and the male tooth belt can be increased. Among them, the "interchangeability" means that when the insertion box assembly is arranged on the female tooth belt, the insertion pin assembly is arranged on the male tooth belt; alternatively, when the insertion box assembly is arranged on the male tooth belt, the insertion pin assembly is arranged on the female tooth belt.

[0025] Further, the insertion box assembly is arranged on the female tooth belt, the insertion pin assembly is arranged on the male tooth belt, and the insertion pin is integrally formed with the male tooth head. This can simplify the structure of the slide rail type socket belt.

[0026] Further, the latch assembly further includes a clamping plate portion disposed beside the latch. A bayonet is provided on the clamping plate portion, and the clamping plate portion can straddle the side wall of the inner cavity of the box through the bayonet. This can increase the difficulty of lateral (left - right direction) separation between the female - threaded belt and the male - threaded belt.

[0027] Further, a notch capable of engaging with the bayonet is provided on the side wall of the inner cavity of the box. This can further increase the difficulty of lateral (left - right direction) separation between the female - threaded belt and the male - threaded belt.

[0028] Further, the socket assembly is disposed on the female - threaded belt, the latch assembly is disposed on the male - threaded belt, and the clamping plate portion is integrally formed with the male - threaded belt handle. This can simplify the structure of the sliding - rail type socket belt.

[0029] Further, the socket assembly is disposed on the female - threaded belt, one end of the box body wraps one end of the female - threaded belt groove body, and the inner cavity of the box body communicates with the groove cavity of the female - threaded belt groove body. In this way, adopting the above - mentioned wrapping structure is beneficial to optimizing the integral appearance effect of the sliding - rail type socket belt.

[0030] Further, the socket assembly further includes a socket connection portion. One end of the socket connection portion is connected to the box body, and the other end is connected to one of the female - threaded belt handle and the male - threaded belt handle. The box body is separately disposed from the female - threaded belt groove body or the male - threaded head on the belt strip connected by the socket assembly. In this way, compared with the above - mentioned wrapping structure, adopting the above - mentioned separation structure can prevent the box body from wrapping and flattening the female - threaded belt groove body or the male - threaded head, thereby damaging the sliding - sleeve plug - in effect between the female - threaded belt and the male - threaded belt.

[0031] Due to the above characteristics and advantages of the present invention, it can be applied to the sliding - rail type socket belt suitable for clothing. Brief Description of the Drawings

[0049] The following further explains the structure of the sliding rail type socket belt applicable to clothing by applying the technical solution of the present invention with reference to the accompanying drawings.

[0050] Such as Figures 1 to 17As shown in the figure, the present invention provides a sliding rail type socket belt applicable to clothing, including a female thread belt 1 and a male thread belt 2; the female thread belt 1 is a flexible profile and extends along the axial direction; in terms of the cross-section, the female thread belt 1 includes a female thread belt handle 11 and a female thread belt groove body 12 integrally formed together, the Shore hardness of the female thread belt groove body 12 is 70-120A, the Shore hardness of the female thread belt handle 11 is not greater than that of the female thread belt groove body 12, the female thread belt groove body 12 has a flared groove cavity 120, the female thread belt handle 11 is used to connect the fabric, the male thread belt 2 is in a T shape and includes a male thread belt head 22 and a male thread belt handle 21, the male thread belt head 22 can be axially slidably installed into the groove cavity 120, the male thread belt handle 21 extends out from the notch of the groove cavity 120, and the male thread belt handle 21 is used to connect the fabric. Wherein, the axial direction is the length direction of the female thread belt 1, that is Figure 1 the X-axis direction in

[0051] The following will detail each specific implementation detail structure and its method. Except for those clearly stated as equivalent or alternative implementation schemes, the various implementation detail schemes disclosed below can be selectively applied or combined and applied in one embodiment even if there is no direct association or synergy in terms of function.

[0052] As Figures 1 to 3As shown, the tooth band 1 is a flexible material that extends axially. Its cross-sectional structure and dimensions are essentially uniform at all points in the axial direction, and it has a specific axial extension length, such as 0.1 meter, 0.3 meter, or 0.5 meter. Lengths of up to 1 meter, 2 meters, or even longer can also be produced in one go, and then cut to suit specific application needs. From a cross-sectional perspective, the tooth band 1 comprises an integrally formed handle 11 and a groove 12. The lateral width of the handle 11 is 2.5 times the lateral width of the groove 12 (e.g., 2, 4, or 8 times, for example, can be selected from a range of 2 to 8 times). This provides sufficient lateral width for direct sewing of the handle 11 to clothing. The Shore A hardness of the handle 11 is no greater than that of the groove 12. In other embodiments, the handle 11 can be made of rubber, braided, or a combination of rubber and braid. In the present embodiment, the female tooth band handle 11 is a TPU soft rubber profile with a Shore hardness of 70 to 120A, and the female tooth band groove body 12 is also a TPU soft rubber profile with a Shore hardness of 70 to 120A. TPU is an environmentally friendly material, and a large number of applications will not cause environmental pollution. Moreover, it has a temperature resistance of up to 180°, and has excellent bending and aging resistance. It is not easily damaged even after multiple bending or in a high temperature environment, and meets the requirements of daily use and service life of clothing. Therefore, TPU is very suitable for manufacturing the female tooth band 1. However, in other embodiments, the female tooth band groove body 12 can also be made of other soft rubber materials such as PVC, EVA, or other soft materials with a Shore hardness of 70 to 120A. In addition, from a cross-section, the female tooth band groove body 12 has a groove cavity 120 in the shape of a bundle. In this way, when the male tooth band head 22 is axially slidably installed in the groove cavity 120, the male tooth band head 22 will not easily move laterally (i.e. Figure 1 Under the action of the pulling force in the Y-axis direction, the female tooth belt 1 passes through the notch of the groove cavity 120 and detaches from the female tooth belt groove body 12, thereby facilitating the maintenance of an effective sliding connection relationship between the female tooth belt 1 and the male tooth belt 2.

[0053] like Figure 4As shown, in cross-section, the male-thread belt 2 is T-shaped and includes a male-thread head 22 and a male-thread belt shank 21. In this embodiment, the male-thread head 22 is a TPU soft rubber profile body with a Shore hardness of 70 to 120A and extends axially (of course, in other embodiments, the male-thread head 22 can also be made of other soft rubber materials such as PVC, EVA, or other soft materials with a Shore hardness of 70 to 120A). In this way, the cross-sectional structure and dimensions of the male-thread head 22 are basically the same at each point in the axial direction and have a certain axial length, such as 0.1 m, 0.3 m, 0.5 m, etc. It is also possible to process a male-thread head 22 that is as long as 1 m, 2 m or longer at one time, and then cut it according to actual application needs. Moreover, the structure with an axial extension length basically does not cause an obvious adverse impact on the flexibility of the entire male-thread belt 2, and is also beneficial to strengthening the sealing performance after the male-thread head 22 and the female-thread belt groove body 12 are sleeved together. In another embodiment, the male-thread head can also be granular, and multiple male-thread heads are axially spaced and arranged on the male-thread belt shank. In this way, the hardness of the male-thread head does not greatly damage the overall flexibility of the male-thread belt, and it can be injection-molded with hard thermoplastic materials such as PP, PC, etc. In addition, the Shore hardness of the male-thread belt shank 21 is not greater than that of the male-thread head 22. In other embodiments, the male-thread belt shank 21 can be a rubber belt shank, a woven belt shank, or a mixed belt shank of rubber and fabric. In this embodiment, the male-thread belt shank 21 is a TPU soft rubber profile body with a Shore hardness of 70 to 120A. The male-thread head 22 and the male-thread belt shank 21 are integrally formed together to form an integral soft profile part. Further, the lateral width of the male-thread belt shank 21 is 4 times the lateral width of the male-thread head 22 (exemplarily, it can also be selected from 4 to 20 times, such as 5, 10, 20 times, etc.). In this way, the male-thread belt shank 21 has a sufficient lateral width to facilitate directly sewing the male-thread belt shank 21 to the clothing. <>

[0054] In this embodiment, the female-thread belt groove body 12 is symmetrically arranged up and down with the thickness center line of the female-thread belt shank 11 as the axis of symmetry, and the male-thread head 22 is symmetrically arranged up and down with the thickness center line of the male-thread belt shank 21 as the axis of symmetry. In another embodiment, as Figure 7 shown, in cross-section, the female-thread belt groove body 12' is offset to the lower side of the female-thread belt shank 11'; the male-thread head 22' is offset to the lower side of the male-thread belt shank 21'. In this way, it is beneficial to optimize the concealment of the female-thread belt groove body 12' and the male-thread head 22'.

[0055] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: Since the female tooth belt 1 is a flexible profile and extends axially, and the Shore hardness of the female tooth belt groove 12 is 70-120A, and the Shore hardness of the female tooth belt handle 11 is not greater than that of the female tooth belt groove 12, thus, the female tooth belt 1 with a relatively long axial extension length can still have ideal flexibility, and when applied to clothing, it can well match the softness of the clothing fabric and will not form obvious rigid belt strips on the clothing, seriously damaging the wearing experience of the clothing; in addition, after the male tooth head is axially slidably installed into the cavity of the female tooth belt groove, a long strip-shaped sealing area is formed between the female tooth belt and the male tooth belt, effectively reducing the air permeability of the sliding rail type socket belt, improving the waterproof effect, and also being beneficial to optimizing the heat preservation effect inside the clothing; secondly, as Figure 6 shown, since the sliding sleeve structures of the female tooth belt and the male tooth belt do not need the assistance of a pull head, that is, there is no need to reserve a sliding space for avoiding the pull head on the female tooth belt handle and the male tooth belt handle, so the fabric 7 can cover the female tooth belt handle and the male tooth belt handle to reduce their exposure, thereby optimizing the concealment effect of the sliding rail type socket belt.

[0056] In addition, in order to prevent the female tooth belt 1 and the male tooth belt 2 together with the sliding sleeve from disengaging, the present invention also proposes an upper stop device, and the specific structure is as follows: As Figures 8 to 16 shown, the upper stop device includes a left stop member 3 provided on the female tooth belt 1 and a right stop member 5 provided on the male tooth belt 2. The left stop member 3 includes a left socket 31, the left socket 31 has a plugging main cavity 310 and a plugging hole 313 that is substantially perpendicular to and penetrates the plugging main cavity 310, and an axial socket 3100 is provided at the head end of the plugging main cavity 310; the right stop member 5 includes a right plug arm 53, the right plug arm 53 includes a main plug arm 51 that can axially pass through the axial socket 3100 and insert into the plugging main cavity 310 and a sub-plug arm 52 that can insert into the plugging hole 313. In this way, when the main plug arm 51 is plugged and combined with the plugging main cavity 310, the sub-plug arm 52 can be kept in a plugged and combined state with the plugging hole 313, thereby increasing the difficulty of axially and laterally separating the female tooth belt 1 and the male tooth belt 2. However, if a sufficiently large axial pulling force is applied (the direction of the force application is the same as that in Figure 5(opposite to the direction indicated by the arrow in the figure), the secondary insertion arm 52 can be deformed to disengage from the insertion hole 313, so that the female tooth belt 1 and the male tooth belt 2 are axially separated. Further, in terms of cross-section, the main insertion cavity 310 is in a flared shape and thus includes a main cavity body 311 and a side cavity opening 312. The main insertion arm 51 is in a T shape and includes a plug 511 and a handle 512. The plug 511 can be axially inserted into the main cavity body 311, and the handle 512 can extend out from the side cavity opening 312. In this way, the difficulty of lateral separation of the female tooth belt 1 and the male tooth belt 2 after they are sleeved together can be increased. Among them, the main cavity body 311 of the main insertion cavity 310 is generally conical, so that the cross-sectional area of the main cavity body 311 gradually decreases from the head end 311a to the tail end 311b. The plug 511 is arranged to fit the main cavity body 311 and is also generally conical, thus having a large-end head 511a and a thin-end tail 511b. In this way, during the process of axially inserting the plug 511 into the main cavity body 311 (such as Figure 5 the direction indicated by the arrow in the figure), taking advantage of the fact that the thin-end tail 511b of the plug 511 is the priority insertion end and is smaller than the axial socket 3100 at the head end 311a, it can be conveniently inserted into the main cavity body 311. The side cavity opening 312 includes a first-segment wide opening 3121 and a tail-segment narrowing opening 3122 that gradually narrows towards the tail end; the handle 512 is arranged to fit the side cavity opening 312 and includes a first-segment thick wall portion 5121 and a tail-segment thin wall portion 5122 that gradually narrows towards the tail end. The first-segment thick wall portion 5121 and the first-segment wide opening 3121 can be tightly fitted together. In this way, during the process of axially inserting the main insertion arm 51 into the main insertion cavity 310, taking advantage of the fact that the tail-segment thin wall portion 5122 of the handle 512 is the priority insertion end and is smaller than the first-segment wide opening 3121, it can be conveniently inserted into the side cavity opening 312. In addition, after the first-segment thick wall portion 5121 and the first-segment wide opening 3121 are tightly fitted together, the difficulty of axial separation of the female tooth belt 1 and the male tooth belt 2 can be increased. Further, as Figure 10 shown, when looking along the depth direction of the insertion hole 313, the insertion hole 313 is in a long strip shape and is arranged obliquely relative to the axis. The diameter of the secondary insertion arm 52 is equivalent to the width of the insertion hole 313. In this way, the difficulty of axial separation of the secondary insertion arm 52 and the insertion hole 313 can be increased, and further the difficulty of axial separation of the female tooth belt 1 and the male tooth belt 2 can be increased. Inspired by the above technical solutions, the positions of the left stop member 3 and the right stop member 5 can be interchanged, which will be introduced in detail below.

[0057] As for the right insertion arm 53, the left socket 31 and the female tooth belt 1 and the male tooth belt 2, one of the following connection methods can be selected. The first connection method (since the structure is simple, the relevant views are omitted): The left stop member 3 is provided on the female tooth belt 1, the left socket 31 wraps one end of the female tooth belt groove body 12, and the insertion main cavity 310 of the left socket 31 communicates with the groove cavity 120 of the female tooth belt groove body 12; the right stop member 5 is provided on the male tooth belt 2, and the right insertion arm 53 wraps one end of the male tooth head 22. In this way, the above wrapping structure is beneficial to optimizing the integral appearance effect of the sliding rail type socket belt. The male tooth head 22 can axially pass through the insertion main cavity 310 and be inserted into the groove cavity 120 of the female tooth belt groove body 12.

[0058] The second connection method: This is also the connection method adopted in this embodiment, as Figure 1 and Figure 2As shown, the left stop member 3 further includes a left connecting portion 32. One end of the left connecting portion 32 is connected to the left socket 31, and the other end is connected to the female-threaded handle 11. The left socket 31 is separated from the female-threaded groove body 12 and arranged axially aligned, and the insertion main cavity 310 of the left socket 31 communicates with the groove cavity 120 of the female-threaded groove body 12 (in another embodiment, the left socket 31 is separated from the female-threaded groove body 12 and offset above the female-threaded groove body 12); the right stop member 5 further includes a right connecting portion 54. One end of the right connecting portion 54 is connected to the right insertion arm 53, and the other end is connected to the male-threaded handle 21. The right insertion arm 53 is separated from the male-threaded head 22 and arranged axially aligned (in another embodiment, the right insertion arm 53 is separated from the male-threaded head 22 and offset above the male-threaded head 22). In this way, compared with the above-mentioned wrapping structure, adopting the above-mentioned separated structure can prevent the left socket 31 and the right insertion arm 53 from wrapping and flattening the female-threaded groove body 12 and the male-threaded head 22, thereby damaging the sliding sleeve insertion effect of the female-threaded belt 1 and the male-threaded belt 2. In the above-mentioned axially aligned manner, the male-threaded head 22 can axially pass through the insertion main cavity 310 and then be inserted into the groove cavity 120 of the female-threaded groove body 12. The positions of the left stop member 3 and the right stop member 5 can be interchanged. For example, in another embodiment, the left stop member 3 is arranged on the male-threaded belt 2, the left socket 31 is separated from the male-threaded head 22 and offset above the male-threaded head 22; and the right stop member 5 is arranged on the female-threaded belt 1, the right insertion arm 53 is separated from the female-threaded groove body 12 and offset above the female-threaded groove body 12. In the case of adopting the offset structure, the following structure can also be adopted. The right insertion arm 53 is in a hook shape, and in terms of cross-section, the insertion main cavity 310 is in a closed ring shape. Another embodiment can also be that the left stop member 3 is arranged on the male-threaded belt 2, the left socket 31 is separated from the male-threaded head 22 and arranged axially aligned; and the right stop member 5 is arranged on the female-threaded belt 1, the right insertion arm 53 is separated from the female-threaded groove body 12 and arranged axially aligned, and an axial channel for the male-threaded head 22 to pass through is provided in the main insertion arm 51.

[0059] In addition, in order to prevent the female-threaded belt 1 and the male-threaded belt 2 from disengaging, the present invention also proposes a lower stop device, and the specific structure is as follows: As Figure 1 , Figure 2 and Figure 17As shown, the lower stop device includes a socket assembly 4 disposed on the female thread belt 1 and a pin assembly 6 disposed on the male thread belt 2. Among them, the socket assembly 4 includes a box body 41 having a box inner cavity 410. The pin assembly 6 includes a pin 61 and a clamping plate portion 62 disposed beside the pin 61. The pin 61 is integrally formed with the male thread head 22, and the clamping plate portion 62 is integrally formed with the male thread belt handle 21. The pin 61 can be axially inserted into the box inner cavity 410. A bayonet 620 is provided on the clamping plate portion 62, and the clamping plate portion 62 can ride on the side box wall 411 of the box inner cavity 410 through the bayonet 620. Further, a notch 4110 capable of engaging with the bayonet 620 is provided on the side box wall 411 of the box inner cavity 410. This can increase the difficulty of the female thread belt 1 and the male thread belt 2 separating horizontally (left and right directions).

[0060] As for the connection between the socket assembly 4 and the female thread belt 1, one of the following connection methods can be selected: The first connection method (since the structure is simple, the relevant views are omitted), the box body 41 wraps one end of the female thread belt groove body 12, and the box inner cavity 410 of the box body 12 communicates with the groove cavity of the female thread belt groove body 12. The second connection method: This is also the connection method adopted in this embodiment. As Figure 1 and Figure 2 shown, the socket assembly 4 further includes a socket connection portion 42. One end of the socket connection portion 42 is connected to the box body 41, and the other end is connected to the female thread belt handle 11. The box body 41 is separated from the female thread belt groove body 12 and arranged axially aligned. Compared with the above wrapping structure, adopting the above separation structure can prevent the box body 41 from wrapping and flattening the female thread belt groove body 12 and damaging the sliding sleeve plugging effect of the female thread belt 1 and the male thread belt 2. In another embodiment, it can also be that the socket assembly 4 and the pin assembly 6 are interchanged in position, that is, the pin assembly 6 is disposed on the female thread belt 1 and the pin 61 is separated from the thread belt groove body 12 and offset above the thread belt groove body 12, and the socket assembly 4 is disposed on the male thread belt 2 and the box body 41 is separated from the male thread head 22 and offset above the male thread head 22.
