[0110] The present invention is described in detail below with reference to the accompanying drawings.

[0111] like Figures 1 to 17 As shown, in an embodiment of the present invention, a two-way luggage retracting lock 1 is provided, comprising:

[0112] The housing 11 has a first side surface provided with a first tape removal opening 111, a second side surface opposite to the first side surface provided with a second tape removal opening 112, and a third side surface adjacent to the first side surface provided with a tightening opening 113;

[0113] The first reel 12 is disposed in the housing 11 and close to one end of the first side surface, and is coaxially connected to a first gear 121;

[0114] The second reel 13 is disposed in the housing 11 and close to one end of the second side surface, and is coaxially connected to a second gear 131;

[0115] a strapping tape 14, one end of which is inserted into the first strapping port 111 and wound around the first reel 12, and the other end of which is inserted into the second strapping port 112 and wound around the second reel 13; and

[0116] The third gear 15 is disposed in the housing 11 and meshes with the first gear 121 and the second gear 131 respectively. A tightening groove 151 is formed adjacent to the tightening opening 113 .

[0117] The solution of the present application adopts a first reel 12 and a second reel 13 to form a double-reel structure to reel the strapping tape 14 in both directions. The active reeling speed is fast, which improves the efficiency of luggage packing. It can also reel in and store longer strapping tape 14 to be suitable for bundling larger luggage, or it can reduce the volume of the sealed bag while accommodating strapping tape 14 of the same length. Specifically, by setting the third gear 15 to engage with the first gear 121 and the second gear 131 respectively, when actively winding the strapping tape 14, the active tightening member 221 of the luggage lock control device 2 is inserted into the tightening groove 151 of the first gear 121 in the two-way winding luggage lock 1, and the luggage lock control device 2 is used to control the active tightening member 221 to rotate to drive the third gear 15 to rotate, so that the first reel 12 on the first gear 121 and the second reel 13 on the second gear 131 rotate synchronously with the third gear 15, so that the strapping tape 14 is bidirectionally wound onto the first reel 12 and the second reel 13 from the first tape taking port 111 and the second tape taking port 112 of the shell 11 respectively, thereby effectively improving the energy efficiency of active winding.

[0118] In one embodiment, a fourth side surface of the housing 11 opposite to the third side surface is provided with an unlocking opening 114;

[0119] The two-way luggage reeling and locking system 1 also includes:

[0120] a ratchet 16, synchronously connected to the first reel 12 or the second reel 13;

[0121] The pawl 17 engages with the ratchet 16 and is provided with an unlocking slot 171 adjacent to the unlocking opening 114. Specifically, in the solution of Document 1, the unlocking buckle must be unlocked before the pawl 17 and the ratchet 16 can be separated, thereby allowing the strapping strap 14 to be stretched. In addition, the unlocking buckle must be unlocked by holding an unlocking card or other unlocking member 19 that controls the lock cylinder mechanism, which brings inconvenience to the use of the device. In contrast, in the solution of the present application, when the strapping strap 14 needs to be stretched, it is only necessary to manually or with external automated equipment to pull the unlocking opening 114 of the pawl 17 away from the ratchet 16. No key or unlocking card is required to unlock the buckle to separate the ratchet 16 and the pawl 17, thereby improving the sealing efficiency and unlocking efficiency.

[0122] In another embodiment, a first return spring 18 is provided at one end of the pawl 17 away from the ratchet 16. Specifically, the first return spring 18 abuts against the pawl 17, causing the pawl 17 to engage with the ratchet 16. The one-way rotation characteristic of the ratchet 16 prevents the strapping belt 14 from stretching, forcing the strapping belt 14 to be retracted, thereby more securely binding the luggage.

[0123] In yet another embodiment, the two-way luggage retracting lock 1 further includes an unlocking member 19 for pushing the pawl 17 to separate from the ratchet wheel 16 .

[0124] In yet another embodiment, the unlocking member 19 comprises:

[0125] The lock seat 191 is provided with a receiving groove 1911;

[0126] The unlocking hook 192 includes a hook portion 1921 , a flange portion 1922 , and a hinge portion 1923 . The hinge portion 1923 is hinged in the receiving groove 1911 , and the hook portion 1921 extends out of the receiving groove 1911 .

[0127] One end of the second return spring 193 is disposed at the bottom of the receiving groove 1911, and the other end abuts against a side of the flange portion 1922 close to the receiving groove 1911. Specifically, the second return spring 193 abuts against the flange portion 1922, causing the hook portion 1921 of the unlocking hook 192 to swing a predetermined angle.

[0128] In some embodiments, a limiting abutment portion 1924 is provided at one end of the unlocking hook 192 close to the hinge portion 1923 , and the second return spring 193 pushes the unlocking hook 192 to rotate a predetermined angle until the limiting abutment portion 1924 abuts against the bottom of the accommodating groove 1911 .

[0129] In some embodiments, a plane rectangular coordinate system is established with the hinge point of the hinge portion 1923 as the origin, the Y-axis is parallel to the movement direction of the pawl 17, and the direction of the Y-axis closer to the pawl 17 is the positive direction, and the X-axis is perpendicular to the movement direction of the pawl 17, and the direction of the X-axis closer to the unlocking hook 192 is the positive direction; wherein:

[0130] The line connecting the hinge point of the hinge portion 1923 and the end point of the hook portion 1921 is denoted as the swing axis L, and the angle between the swing axis L and the X-axis is denoted as θ, and 0°<θ≤85°;

[0131] The end point of the hook portion 1921 is marked as M, and the coordinates of point M are marked as a, b, where a>0 and b>0. Specifically, θ is the angle between the swing axis L and the X axis when the unlocking hook 192 is in a normal state, that is, in a non-rotating state. Figure 8 As shown, the plane rectangular coordinate system is constructed. Correspondingly, the angle between the swing axis L and the Y axis is λ, then λ = 90° - θ. Furthermore, 10° ≤ θ ≤ 80°. Preferably, θ = 70°.

[0132] In some embodiments, the housing 11 is provided with a guide slot 115 communicating with the unlocking port 114. The pawl 17 is placed in the guide slot 115. The unlocking slot 171 is a through slot or a blind slot. Specifically, the pawl 17 can reciprocate in the guide slot 115. When unlocking:

[0133] In the first embodiment, the unlocking groove 171 is a through groove. The hook portion 1921 of the unlocking hook 192 extends into the unlocking opening 114 and passes through the unlocking groove 171 of the pawl 17, and finally abuts against the bottom wall of the guide groove 115 on the side away from the unlocking opening 114. Since the unlocking hook 192 has a certain inclination, the hook portion 1921 slides a distance on the bottom wall. The flange portion 1922 of the unlocking hook 192 compresses the second return spring 193. During the sliding process, the hook portion 1921 pushes the pawl 17 away from the ratchet 16. At the same time, the pawl 17 compresses the first return spring 18. After the pawl 17 is separated from the ratchet 16, the strapping belt 14 can be stretched.

[0134] In the second embodiment, the unlocking groove 171 is a blind groove, which has the same concept as the blind hole. The hook portion 1921 of the unlocking hook 192 extends into the unlocking opening 114 and then inserts into the unlocking groove 171 until it abuts against the bottom wall of the unlocking groove 171. Since the unlocking hook 192 has a certain slope, the hook portion 1921 slides along the bottom wall of the unlocking groove 171 for a distance until it abuts against the side wall of the unlocking groove 171. Then, the hook portion 1921 continues to slide and pushes the pawl 17 away from the ratchet 16. At the same time, the pawl 17 compresses the first return spring 18.

[0135] When locking, it is only necessary to withdraw the unlocking hook 192 from the unlocking slot 171 of the pawl 17. By withdrawing the thrust of the unlocking hook 192, the first return spring 18 will release the elastic force and push the pawl 17 to re-engage with the ratchet 16, so that the strapping belt 14 cannot be stretched.

[0136] In some embodiments, the first reel 12 is synchronously connected to a first coil spring, and the second reel 13 is synchronously connected to a second coil spring. Specifically, the first and second coil springs are configured to enable the first and second reels 12, 13 to actively reel in the strapping tape 14. The dual reel and dual coil spring design enhances the reeling force, increasing the tightening force on the luggage and improving the binding effect.

[0137] In some embodiments, the bottom of the housing 11 is provided with a pulling groove 116, and the strapping tape 14 is wrapped around the bottom of the housing 11. Specifically, there are two pulling grooves 116, and the pulling rod of the pulling mechanism is inserted into the pulling grooves 116 and dragged downward, thereby pulling the strapping tape 14 out from the first reel 12 and the second reel 13 in the housing 11 and stretching it to a predetermined length.

[0138] In some embodiments, the unlocking member 19 includes a handle and an unlocking hook 192 connected to the handle, and the end of the unlocking hook 192 is provided with a hook portion 1921. Specifically, when unlocking:

[0139] In implementation three, push the handle so that the unlocking hook 192 extends into the unlocking port 114 and is inserted into the unlocking slot 171 of the pawl 17. By driving the handle to control the hook portion 1921 of the unlocking hook 192, the pawl 17 is pushed against the guide groove 115 until the pawl 17 and the ratchet wheel 16 are separated. At the same time, the pawl 17 compresses the first return spring 18.

[0140] The present invention further provides another embodiment, a luggage lock control device 2, which is used to control the bidirectional luggage retracting luggage lock 1 as described above, and includes:

[0141] The main bracket 21 is provided with a first guide rail 211 and a second guide rail 212 at both ends;

[0142] A sub-bracket 22, having two ends movably connected to the first guide rail 211 and the second guide rail 212, respectively. An active tightening member 221 corresponding to the tightening groove 151 is provided at one end close to the second guide rail 212, and a first driving mechanism 222 for driving the active tightening member 221 to rotate is provided at one end close to the first guide rail 211;

[0143] The pusher 23 is movably connected to the end of the second guide rail 212 away from the sub-bracket 22 and is synchronously connected to the lock seat 191;

[0162] In some embodiments, the active tightening member 221 is provided with a fourth return spring 2211 and a retaining spring 2212 .

[0163] The present invention further provides another embodiment, a belt pulling mechanism, comprising:

[0164] Pull the rod;

[0165] A third driving mechanism drives the pull rod to insert into the pull slot 116 of the aforementioned two-way luggage retracting lock 1; and

[0166] The fourth driving mechanism drives the strapping rod to move away from the strapping groove 116. Specifically, when the ratchet 16 and the pawl 17 are separated, the strapping strap 14 can be stretched. The third driving mechanism drives the strapping rod to insert into the strapping groove 116. Then, the fourth driving mechanism drives the strapping rod to move along the guide rail until the strapping rod is away from the strapping groove 116. During this process, the strapping rod will pull out and stretch the strapping strap 14 in the notch of the strapping groove 116.

[0167] The present invention further provides another embodiment, a luggage sealing method, comprising the following steps:

[0168] Clamping step: the first limit block 291 and the second limit block 292 of the lock control device 2 tightly clamp the two-way retractable luggage lock 1;

[0169] Unlocking step: The pusher 23 pushes the lock seat 191 to move synchronously, so that the unlocking hook 192 is inserted into the unlocking slot 171 of the pawl 17, and the hook portion 1921 of the unlocking hook 192 pushes the pawl 17 away from the ratchet 16;

[0170] Drawing step: pulling the strapping tape 14 outward from the housing 11 for bidirectionally winding and sealing the luggage to a predetermined length;

[0171] Binding step: The luggage is conveyed into the stretched strapping belt 14, and the first driving mechanism 222 drives the active tightening member 221 to rotate, thereby driving the third gear 15 to rotate, thereby causing the first reel 12 and the second reel 13 to reel in the strapping belt 14 until the strapping belt 14 is tightly bound to the luggage;

[0172] Locking Steps: The second drive mechanism 244 drives the rotary disk 241 to rotate in a direction opposite to the first direction, causing the sub-bracket 22 and the pusher 23 to move away from each other. The unlocking hook 192 withdraws from the unlocking slot 171 of the pawl 17, and the first return spring 18 pushes the pawl 17 and the ratchet 16 to engage. Specifically, after the pawl 17 and the ratchet 16 engage, the strapping strap 14 cannot extend outward, making the strapping strap 14 more secure and reliable in binding the luggage and preventing the strapping strap 14 from loosening.

[0173] In some embodiments, the clamping step further includes:

[0174] Initialization step: Place the two-way luggage lock lock 1 between the first limit block 291 and the second limit block 292 of the lock lock control device 2 in a predetermined direction, wherein the predetermined direction includes the tightening opening 113 of the two-way luggage lock lock 1 and the active tightening member 221 of the lock lock control device 2 being in the same direction.

[0176] Pre-tightening step: The active tightening member 221 moves synchronously with the sub-bracket 22 until it is inserted into the tightening groove 151 .

[0177] In some embodiments, the step after the clamping step further includes:

[0178] Pre-unlocking step: the second driving mechanism 244 drives the turntable 241 to rotate in the first direction, the first guide shaft 2421 and the second guide shaft 2431 move along the first arc guide groove 2411 and the second arc guide groove 2412 respectively and approach each other, driving the first guide seat 242 and the second guide seat 243 to move synchronously with the first guide shaft 2421 and the second guide shaft 2431 respectively and approach each other, so that the sub-bracket 22 and the pushing member 23 move synchronously with the first guide seat 242 and the second guide seat 243 respectively and approach each other.

[0179] In some embodiments, the strapping step includes inserting a strapping rod of the strapping mechanism into the strapping slot 116 of the two-way retractable luggage lock 1 and pulling the strapping tape 14 outward to extend the strapping tape 14 to a predetermined length.

[0180] In detail:

[0181] refer to Figure 13 and Figure 14 The device includes an outer frame 25, which serves as the mounting plate for the entire device. A base 26 is mounted on the outer frame 25, on which two linear bearings are mounted. A set of linear guide rails, namely a third guide rail 281 and a fourth guide rail 282, are mounted on the outer frame 25. Their corresponding sliders are connected to the lift plate 213 via an adapter plate. Two guide posts 27 are mounted on the upper end of the lift plate 213. The guide posts 27 pass through the inner rings of the linear bearings. A third return spring 271 is mounted on the shaft of the guide post 27. One end of the third return spring 271 contacts the lift plate 213, and the other end contacts the linear bearings. A limit plate is mounted on the shaft end of the guide post 27. Therefore, assuming the outer frame 25 and base 26 are stationary, when a certain upward force is applied to the lift plate 213, the lift plate 213 moves upward relative to the base 26 under the guidance of the linear bearings, guide posts 27, and linear guide rails. When the applied force disappears, the lift plate 213 moves downward relative to the base 26 under the compressive force of the third return spring 271, and returns to its initial position under the restraint of the stop plate. A first stop block 291 is installed below the lift plate 213. A stop rubber pad is installed on the first stop block 291 to guide and limit the two sides of the lock. A rubber pad is installed at the lower end of the lift plate 213 to prevent hard contact between the lock and the lift plate 213 during clamping.

[0182] refer to Figures 15-17 A motor mount 2191 is mounted above the lift plate 213. A second drive mechanism 244, specifically a turntable 241 motor, is mounted on the motor mount 2191. The turntable 241 is mounted on the motor's output shaft. The lift plate 213 is also equipped with a second guide rail 212. The second guide rail 212 is equipped with two sliders, each of which is equipped with a first guide seat 242 and a second guide seat 243. The protruding shafts of the first and second guide seats 242 and 243, respectively, are constrained within the first and second arcuate guide slots 2411 and 2412 of the turntable 241. The motor drives the turntable 241 to rotate clockwise, causing the first and second guide seats 242 and 243 at either end to move downward toward each other under the guidance of the first and second arcuate guide slots 2411 and 2412 of the turntable 241 and the second guide rail 212. The motor driving the turntable 241 controls the turntable 241 to rotate counterclockwise, thereby performing reverse movement.

[0183] refer to Figure 10 and Figure 11 The first and second guide seats 242 and 243 at either end are connected to the unlocking member 19 and the take-up device, respectively. This is used to unlock and take up the baggage lock 1 for bidirectional retraction. The main bracket 21 includes a motor mount 2191 and an upper mounting plate 2192. The upper mounting plate 2192 is secured above the motor mount 2191, and the first guide rail 211 is secured above the upper mounting plate 2192. The slider of the first guide rail 211 is connected to the take-up device via a connecting plate, providing guidance. Driven by the motor on the turntable 241, the unlocking member 19 and the take-up device also achieve movement toward and in opposite directions.

[0184] refer to Figure 10 and Figure 11 The tape-taking device includes a sub-bracket 22, which is connected to the first guide seat 242 and the second guide seat 243 at the bottom and is connected to the slider of the first guide rail 211 at the top through a connecting plate. A pad is installed on the sub-bracket 22, and a first drive mechanism 222, i.e., the tape-taking motor, is installed on the pad. A synchronous wheel 214 is fixed to the output shaft of the tape-taking motor. A pair of flange bearings 2213 are installed at the bottom of the sub-bracket 22, and the inner rings of the flange bearings 2213 are connected to the synchronous wheel 214. The inner hole of the synchronous wheel 214 is penetrated by an active tightening member 221, i.e., a drive wrench. The drive wrench is designed to be hexagonal, imitating an inner hexagonal wrench, and the left part is designed to be a ball head style to facilitate alignment when connected with the sealing block. The inner hole of the synchronous wheel 214 is also designed to be hexagonal, and the drive wrench slides inside the synchronous wheel 214 and does not rotate relative to it. The drive wrench shaft is equipped with a retaining spring 2212 and a fourth return spring 2211. These springs compress the drive wrench to the right, returning it to its original position when no external force is applied. Driven by the first and second guide seats 242 and 243, the drive wrench moves leftward, its hexagonal ball inserting into the tightening opening 113 of the two-way luggage rewinding lock 1 and into the tightening groove 151 of the third gear 15, completing the rewinding operation. The fourth return spring 2211 ensures a certain preload on the drive wrench. A rubber pressure block 2214 is mounted on the sub-bracket 22 to limit the lock.

[0185] refer to Figure 7 Unlocking member 19 comprises a small push plate with a lock base 191 mounted below. A pin is fixed to lock base 191, and an unlocking hook 192 is hingedly mounted within lock base 191. A second return spring 193 is mounted on the small circular column of the lock hook, automatically returning the unlocking hook 192 to its original position. The unlocking process is explained below in conjunction with the application of the lock.

[0186] refer to Figures 1 to 6Initially, the unlocking member 19 is not in contact with the locking block. The locking pawl 17, under the action of the first return spring 18, blocks the ratchet 16, preventing it from rotating clockwise and preventing the strap 14 from being pulled out. At this point, the unlocking hook 192 of the unlocking member 19, under the action of the second return spring 193, causes the limiting abutment 1924 on its tail end face to abut against the inner wall of the lock seat 191. Driven by the motor of the turntable 241, the unlocking member 19 moves forward, and the head of the unlocking hook 192 penetrates the locking block. The limiting abutment 1924 of the unlocking hook 192 contacts the inner wall of the lock seat 191, causing the unlocking member 19 to rotate clockwise. The protrusion on the right side of the hook portion 1921 of the unlocking hook 192 contacts the right inner wall of the pawl 17, gradually driving the pawl 17 to slide to the right, eventually leaving the circumference of the tooth tip circle of the ratchet 16. At this point, the unlocking process is complete, and the strap 14 can be pulled out. At this point, the end face of the lock seat 191 is in contact with the housing 11 of the lock, and together with the rubber pressure block 2214 on the take-up mechanism and the rubber pads installed on the first limit blocks 291 on both sides of the lift push plate 213, the lock is confined within the space, ensuring the positioning accuracy of the lock during subsequent movement. The unlocking member 19 is driven backward by the motor of the turntable 241. The unlocking hook 192 gradually returns to its original position under the action of the inner wall of the lock seat 191 and the second return spring 193. The pawl 17 also re-engages the ratchet 16 under the action of the first return spring 18. Even if the teeth of the latch pin and ratchet 16 occasionally do not align properly, the pawl 17 can re-engage the ratchet 16 after the external force pulls the belt and the ratchet 16 rotates slightly.

[0187] The complete process is as follows: (not shown in the figure of the locking mechanism) the locking block is transported to the position directly below the unlocking and taking-up device. By controlling the lifting of the locking block or the lowering of the unlocking and taking-up device, the top end surface of the locking block is aligned with the rubber pad installed on the bottom of the lifting push plate 213 under the guidance of the limiting rubber pads of the first limit block 291 and the second limit block 292. During this process, the motor of the turntable 241 drives the turntable 241 to rotate, driving the unlocking member 19 and the active tightening member 221 at both ends toward the lock. The unlocking hook 192 of the unlocking member 19 extends into the locking block to complete the unlocking. The ball head of the driving wrench of the active tightening member 221 at the other end extends into the hexagonal groove of the gear of the locking block when the hexagonal alignment is in place. If not, only the ball head partially extends under the action of the fourth return spring 2211. When the strapping strap 14 is pulled out by the strapping mechanism, the gear rotates under the action of the gear meshing. After the gear rotates to the appropriate angle, the ball head of the driving wrench is hexagonally aligned and snaps into the inner groove of the gear. At this point, the take-up motor is disabled, and applying a small force causes the motor's output shaft to rotate. This allows the external mechanism to overcome the resistance of the motor on turntable 241 and pull the belt. Mounting bracket 216 is mounted on base 26, on which is mounted a sensor switch 217. Upper mounting plate 2192 is mounted with a sensor plate 218. During the luggage sealing process, the seal is pressed against the luggage, causing relative displacement between upper mounting plate 2192 and base 26. The sensor switch 217 detects the signal from sensor plate 218, and the motor on turntable 241 drives the turntable 241 to rotate, driving the unlocking member 19 and active tightening member 221 at both ends away from the seal block, thus securing the seal to the luggage.

[0188] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
