Description

Technical Field

[0001] The utility model relates to the technical field of police equipment, and more specifically, to a disposable restraint belt. Background Art

[0002] Handcuffs are commonly used police equipment. Traditional handcuffs are generally metal handcuffs that can only restrain the wrists horizontally. Due to structural shape limitations, in order to be suitable for more people, the handcuffs are designed to have a larger space. Therefore, when the handcuffs are turned, there is still free space in the metal handcuffs, which creates the risk of escape. In addition, metal handcuffs are relatively heavy and bulky, making them inconvenient to carry. Utility Model Content

[0003] The utility model aims to overcome the problems that metal handcuffs are heavy and bulky, inconvenient to carry and have the risk of escape, and to provide a disposable restraint belt which is small in size, light in weight, more reliable in restraint and convenient to carry.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A disposable restraint belt comprises a binding part and a fixed part, wherein the binding part is movably arranged in the fixed part; the binding part is a strip-shaped or strip-shaped structure, and the fixed part comprises an outer shell and a lock core, wherein a plurality of channels which all penetrate through both sides of the outer shell are sequentially arranged in the outer shell, and the binding part forms a closed structure on both sides of the outer shell after passing through each channel in sequence, wherein the closed structure is defined as a cuff ring, wherein the binding part is located on one side of the outer shell to form at least two independent cuff rings, and the binding part is located on the other side of the outer shell to form a pulling part, and a chamber for accommodating the lock core is further arranged in the outer shell, wherein the chamber is communicated with a channel close to an end of the outer shell, and the lock core is movably connected to the outer shell, and the lock core is clamped with the binding parts located at both ends inside the outer shell.

[0006] The binding part of the utility model includes a pulling part and a cuff ring, the cuff ring acts on the wrist to restrict the movement of both hands, and the setting of the pulling part can facilitate the tightening of the cuff ring; the fixed part includes a shell and a lock core, the shell is used to provide an installation space for the lock core, and through the setting of multiple channels in the shell, the binding part is passed through to form the shape of the pulling part and the cuff ring, and the cuff ring and the pulling part can be linked; the lock core has a one-way locking function, when it acts on the pulling part and pulls, it can unlock and tighten the cuff ring, but when it acts on the cuff ring, the lock core will be locked, thereby preventing the cuff ring from loosening, thereby reducing the risk of personnel escaping. Specifically, by pulling the pulling part, the pulling part drives the lock core to move upward, thereby separating the lock core from the binding part, the binding part loses the pressing force and tightens the cuff ring at the same time, after the pulling part is released, when the cuff ring wants to open, the lock core moves downward under the force of the cuff ring, so that it resumes the clamping connection with the binding part, the binding part is compressed, and the binding work is completed.

[0007] Furthermore, there are four channels, the chamber and the lock core are both one, a partition plate is provided in the middle of the chamber, two channels are located in the space formed by the partition plate, and the other two channels are located between the partition plate and the inner wall of the shell, and the two ends of the lock core are respectively engaged with the binding parts in the channels between the partition plate and the inner wall of the shell. The chamber is arranged in a ring shape in the shell, and the middle of the chamber is separated by the partition plate to facilitate the arrangement of the two channels in the middle of the lock core. The binding part passes through the channel located at the end of one side of the shell to the other side of the shell, and then returns to the initial side from the adjacent channel, and then passes through another adjacent channel. After passing through each channel in turn, the binding part returns to the same side of the shell that was initially penetrated. At this time, the binding part on the penetration side forms a pulling part, and the binding part on the opposite side of the shell forms two independent cuff rings, which can act on the two ends of the pulling part to reduce the space of the cuff ring. Within the scope of cognition of those skilled in the art, the cuff rings are not limited to two, and more channels can be arranged in the shell as needed, so that the binding part can form a larger number of cuff rings after passing through in turn.

[0008] Furthermore, there are four channels, two chambers and two lock cores, and the two chambers are located at the two ends of the shell, two of which are located between the two chambers, and the other two are located between the chamber and the ends of the shell, and the two lock cores are respectively engaged with the binding parts in the channels between the chamber and the ends of the shell. The two chambers are independently arranged, and the two lock cores are respectively installed in two different chambers. The chambers are arranged at the two ends of the shell so that when the pulling part is tightened, the lock core can be moved up, thereby separating the binding part from the lock core, thereby reducing the space of the handcuff ring.

[0009] Furthermore, the two channels in the middle of the housing are connected at the pulling portion side of the housing. Within the knowledge of those skilled in the art, the two channels in the middle can also be independently arranged and not connected to each other.

[0010] Furthermore, the chamber is tilted at a certain angle near the inner side of the shell, and the cross-sectional area of ​​the chamber on the pulling part side is larger than the cross-sectional area of ​​the chamber on the handcuff ring side. The tilted chamber allows the lock core to move toward the pulling part side, i.e., the larger chamber space, when the pulling part is pulled, which facilitates the separation of the lock core from the binding part, and further facilitates the locking of the handcuff ring; and when force is applied to the handcuff ring, the lock core moves toward the handcuff ring side, i.e., the smaller chamber space, which is conducive to the lock core pressing the binding part, and then the lock core and the binding part are engaged, preventing the handcuff ring from being stretched open.

[0011] Furthermore, a first sliding part is provided on the lock core, and a second sliding part is provided in the shell, and the first sliding part is slidably connected to the second sliding part. The first slide part can be a slide rail, and the second sliding part can be a slide groove. Through the cooperation of the slide groove and the slide rail, the lock core and the shell are slidably connected, which is convenient for guiding the lock core and the shell when they move relative to each other, and is also convenient for locking and maintaining the locked state of the handcuff ring. Within the scope of cognition of those skilled in the art, the first sliding part can also be a slide groove, the second sliding part can also be a slide rail, or the first sliding part and the second sliding part can both be other structures that can be used to achieve sliding connection.

[0012] Furthermore, the lock core is provided with a plurality of teeth for engaging with the binding part. The provision of the teeth facilitates the engagement of the lock core with the binding part located in the housing; preferably, the teeth are arranged at a certain angle to form a ratchet structure, which is beneficial to the one-way locking function of the lock core. When the lock core moves upward, the size of the pulling part can be increased, thereby reducing the size of the cuff ring. However, when the cuff ring is forced outward, the lock core will move downward, thereby reducing the space between the lock core and the binding part. Due to the unidirectionality of the ratchet, the lock core and the binding part will only become tighter and tighter when the force is greater, thereby preventing the cuff ring from being stretched and loosened, thereby reducing the risk of escape.

[0013] Furthermore, the pulling part is a closed ring structure. The pulling part is arranged in a closed ring structure, which can facilitate force application, and only a single force is applied on the pulling part to achieve pulling of the pulling part, thereby tightening the handcuff ring.

[0014] Furthermore, the binding part also includes a clasp for closing and locking the strip or belt structure, and the clasp is located on the pulling part and connected to the two ends of the strip or belt structure. The clasp is used to connect the two ends of the pulling part, so that the pulling part of the strip or belt structure is closed, which is convenient for applying force to the pulling part.

[0015] Furthermore, the housing comprises a shell and a cover, and the cover is detachably arranged on the top of the shell. The housing is arranged in a split manner, which facilitates the installation of the lock core.

[0016] Furthermore, the strip or band structure is a rope. The material of the rope can be selected accordingly according to the needs to meet the functional needs, ensuring sufficient strength and flexibility to meet the needs of limiting the movement of the wrist and ensuring that no personal injury is caused.

[0017] Furthermore, a clamping boss for cooperating with the lock core is provided in the chamber and near the outer side of the shell, and the clamping boss is integrally formed with the shell. The clamping boss can cooperate when the lock core moves downward, further improving the clamping and locking of the lock core and the restraining part.

[0018] The beneficial effects of the utility model are:

[0019] When the handcuff ring of the restraint belt is still in the restrained state, the pulling part is pulled to drive the lock core to slide upward, so that the inserting teeth of the lock core are separated from the restraining part located in the shell, so that the restraining part can be pulled upward, thereby increasing the size of the pulling part and reducing the size of the handcuff ring to achieve a further locking effect on the handcuff ring; when the handcuff ring wants to be opened, the lock core slides downward under the action of the handcuff ring, so that the inserting teeth of the lock core and the pressing boss of the cavity press the restraining part, so that the restraining part cannot be pulled downward, thereby ensuring that the size of the handcuff ring is maintained in its original state and will not be opened. Compared with traditional metal handcuffs that are relatively heavy and bulky, inconvenient to carry and have the risk of escape, the disposable restraint belt of the utility model is small in size, light in weight, high in strength, and more reliable in restraint, and more convenient to carry.

[0032] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0033] Example 1

[0034] like Figures 1 to 8 The utility model is shown as an embodiment 1 of a disposable restraint belt, comprising a binding part and a fixed part, wherein the binding part is movably arranged in the fixed part; the binding part is a strip-shaped or belt-shaped structure, preferably, a rope; the fixed part comprises an outer shell 3 and a lock core, wherein the outer shell 3 is provided with a plurality of channels which all pass through both sides of the outer shell 3 in sequence, and the binding part forms a closed structure on both sides of the outer shell 3 after passing through each channel in sequence, wherein the closed structure is defined as a cuff ring 2, wherein the binding part is located on one side of the outer shell 3 to form at least two independent cuff rings 2, and the binding part is located on the other side of the outer shell 3 to form a pulling part 1, and a chamber for accommodating the lock core is also provided in the outer shell 3, wherein the chamber is connected with the channel near the end of the outer shell 3, the lock core is movably connected with the outer shell 3, and the lock core is clamped with the binding parts located at both ends inside the outer shell 3.

[0035] The binding part of the utility model comprises a pulling part 1 and a cuff ring 2, the cuff ring 2 acts on the wrist to restrict the movement of both hands, and the setting of the pulling part 1 can facilitate the tightening of the cuff ring 2; the fixing part comprises a shell 3 and a lock core, the shell 3 is used to provide an installation space for the lock core, and through the setting of multiple channels in the shell 3, the binding part is passed through to form the shape of the pulling part 1 and the cuff ring 2, and the cuff ring 2 and the pulling part 1 can be linked; the lock core has a one-way locking function, when it acts on the pulling part 1 and pulls, it can unlock and tighten the cuff ring 2, but when it acts on the cuff ring 2, the lock core will be locked, thereby preventing the cuff ring 2 from loosening, thereby reducing the risk of personnel escape. Specifically, by pulling the pulling part 1, the pulling part 1 drives the lock core to move upward, thereby separating the lock core from the binding part, and the binding part loses the clamping force and tightens the cuff ring 2 at the same time. After loosening the pulling part 1, when the cuff ring 2 wants to open, the lock core moves downward under the action of the cuff ring 2, so that the locking connection with the binding part is restored, the binding part is compressed, and the binding work is completed.

[0036] There are four channels, two chambers and two lock cores, and the two chambers are located at the two ends of the shell 3, two of which are located between the two chambers, and the other two are located between the chamber and the end of the shell 3, and the two lock cores are respectively engaged with the binding parts in the channels between the chambers and the ends of the shell 3. Specifically, the channels are the first channel 51, the second channel 52, the third channel 53, and the fourth channel 54 from left to right. The chamber on the left is the left chamber 61, and the chamber on the right is the right chamber 62. The left chamber 61 and the right chamber 62 are independently arranged. The lock cores are the first lock core 41 and the second lock core 42, respectively. The first lock core 41 is installed in the left chamber 61, and the left chamber 61 is connected to the first channel 51. The left side of the first lock core 41 is engaged with the binding part in the first channel 51; the second lock core 42 is installed in the right chamber 62, and the right chamber 62 is connected to the fourth channel 54, and the right side of the second lock core 42 is engaged with the binding part in the fourth channel 54. Further, the two channels located in the middle of the housing 3 are connected at the pulling portion 1 side of the housing 3, such as Figure 3 Of course, the second channel 52 and the third channel 53 can also be independently provided and not connected to each other, such as Figure 8 As shown; the left chamber 61 and the right chamber 62 are respectively arranged at the two ends of the shell 3 so that when the pulling part 1 is tightened, the first lock core 41 and the second lock core 42 can move up, thereby separating the binding parts located at the two ends of the shell 3 from the two lock cores, thereby reducing the space of the handcuff ring 2.

[0037] Moreover, the chamber is tilted at a certain angle near the inner side of the shell 3, and the cross-sectional area of ​​the chamber on the side of the pulling part 1 is larger than the cross-sectional area of ​​the chamber on the side of the cuff ring 2. The tilted left chamber 61 and the right chamber 62 enable the lock core to move toward the side of the pulling part 1, i.e., the larger space of the left and right chambers 62, when the pulling part 1 is pulled, so as to facilitate the separation of the first lock core 41 and the second lock core 42 from the binding parts at both ends of the shell 3, and further facilitate the locking of the cuff ring 2; and when the force is applied at the cuff ring 2, the first lock core 41 and the second lock core 42 move toward the side of the cuff ring 2, i.e., the smaller space of the left and right chambers 62, which is conducive to the first lock core 41 and the second lock core 42 to press the binding parts, and further enable the first lock core 41 and the second lock core 42 to engage with the binding parts at both ends of the shell 3, and prevent the cuff ring 2 from being stretched open.

[0038] As an improved solution of the present embodiment, a first sliding part is provided on the lock core, a second sliding part is provided in the housing 3, and the first sliding part is slidably connected to the second sliding part. The first slideway part can be a slide rail, and the second sliding part can be a chute. Through the cooperation of the chute and the slide rail, the lock core and the housing 3 are slidably connected, which is convenient for guiding the lock core and the housing 3 when they move relative to each other, and is also convenient for locking and maintaining the locked state of the handcuff ring 2. Within the scope of cognition of those skilled in the art, the first sliding part can also be a chute, the second sliding part can also be a slide rail, or the first sliding part and the second sliding part are other structures for realizing sliding connection.

[0039] Moreover, a plurality of insert teeth 43 for engaging with the binding part are provided on the outer sides of the first lock core 41 and the second lock core 42. The provision of the insert teeth 43 facilitates the engagement of the first lock core 41 and the second lock core 42 with the binding part located in the housing 3; preferably, the insert teeth 43 are arranged at a certain angle to form a ratchet structure, which is beneficial to the one-way locking function of the lock core. When the lock core moves upward, the size of the pulling part 1 can be increased, thereby reducing the size of the cuff ring 2. However, when the cuff ring 2 is forced outward, the lock core will move downward, thereby reducing the space between the lock core and the binding part. Due to the unidirectionality of the ratchet, the lock core and the binding part will only get tighter and tighter when the force is greater, so the cuff ring 2 can be prevented from being stretched and loosened, thereby reducing the risk of escape.

[0040] In addition, the housing 3 includes a shell 32 and a cover 31, and the cover 31 is detachably covered on the top of the shell 32. The split housing 3 facilitates the installation of the first lock core 41 and the second lock core 42.

[0041] As an improved solution of this embodiment, the pulling part 1 is a closed ring structure, and the strip or belt structure is a rope. The pulling part 1 is set in a closed ring structure, which can facilitate the application of force. Only by applying force at a single point on the pulling part 1, the pulling of the pulling part 1 can be achieved, thereby tightening the cuff ring 2. When it is necessary to release the restraint of the restraint belt on both hands, only the cuff ring part needs to be cut off at any position to free the hands. The cuff ring of the utility model is disposable. When the restraint belt needs to be reused, only the pulling part and the cuff ring can be replaced, while the shell and the lock core part can be reused.

[0042] As an improvement to this embodiment, a clamping boss 321 for cooperating with the lock core is provided in the chamber and located near the outer side of the housing 3. The clamping boss 321 is integrally formed with the housing 3. The clamping boss 321 can cooperate when the lock core moves downward, further improving the clamping and locking of the lock core and the restraining part.

[0043] Specifically, a clamping boss 321 is provided at the left chamber 61 located on the left side of the shell 32 and at the right chamber 62 located on the right side of the shell 32, which can cooperate when the first lock core 41 and the second lock core 42 move downward, further improving the clamping and locking of the first lock core 41 and the second lock core 42 with the binding part.

[0044] Example 2

[0045] This embodiment is embodiment 2 of a disposable restraint belt. This embodiment is similar to embodiment 1, except that there are four channels, and there is one chamber and one lock core. An isolation plate 7 is provided in the middle of the chamber, two of the channels are located in the space formed by the isolation plate 7, and the other two channels are located between the isolation plate 7 and the inner wall of the outer shell 3. Both ends of the lock core are respectively engaged with the restraining parts in the channels between the isolation plate 7 and the inner wall of the outer shell 3.

[0046] In this embodiment, similar to the embodiment 1, the channels are the first channel 51, the second channel 52, the third channel 53, and the fourth channel 54 from left to right, but the left chamber 61 and the right chamber 62 in the embodiment 1 are connected and combined into one, forming a large chamber. Similarly, the lock core in this embodiment is the first lock core 41 and the second lock core 42 in the embodiment 1 connected as a whole, and the two are combined into one; in this embodiment, the chamber is arranged in an annular shape in the shell 3, and the middle of the chamber is separated by an isolation plate 7 to facilitate the arrangement of two channels in the middle of the lock core. The binding part passes through the channel at the end of one side of the shell 3 to the other side of the shell 3, and then returns to the initial side from the adjacent channel, and then passes through another adjacent channel. After passing through each channel in turn, the binding part returns to the same side of the shell 3 that was initially penetrated. At this time, the binding part on the penetration side forms a pulling part 1, and the binding part on the opposite side of the shell 3 forms two independent cuff rings 2, which can act on the two ends of the pulling part 1 to reduce the space of the cuff ring 2. It is within the knowledge of those skilled in the art that the number of cuff rings 2 is not limited to two, and more channels can be provided in the outer shell 3 as needed, so that the restraining parts can be passed through and wound in sequence to form a greater number of cuff rings 2.
