Description

Technical Field

[0001] This utility model relates to the field of luggage accessories technology, and in particular to a simple luggage fastening lever. Background Technology

[0002] A rolling suitcase is a type of bag that adds wheels and a pull rod to the basic bag design, allowing it to be pulled and reducing weight. Nowadays, rolling suitcases have become an indispensable item for people traveling. The pull rod is an important component of the rolling suitcase, serving to support the bag and facilitate its movement. When the pull rod is damaged, it needs to be replaced. However, existing bags come in different sizes, and the connecting seat on the pull rod may not match the threaded hole on the bag. Therefore, a new type of pull rod is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a simple fastening lever for bags.

[0005] To achieve the above objectives, the technical solution of this utility model is: a simple fastening pull rod for bags, comprising a handle and two rods, both of which are fixedly connected to the handle. Each rod is provided with a connecting seat for fixing to the bag, and the connecting seat is provided with two connecting ears for connecting to the bag. Each connecting ear is provided with a through hole. The connecting seat is slidably connected to the two rods. A fixing mechanism for fixing the connecting seat is provided inside the connecting seat. The fixing mechanism includes two rollers, which are respectively disposed on both sides of one of the rods. One roller is rotatably connected to the connecting seat, and the connecting seat is provided with a limiting mechanism for restricting the rotation of the roller. The other roller is rotatably connected to the connecting seat through a pressing mechanism. The two rollers are pressed tightly against the rods by the pressing mechanism.

[0006] By adopting the above technical solution, the connecting seat can be matched with the threaded hole on the bag through the through hole on the connecting ear. By passing a screw through the through hole and threading it into the threaded hole of the bag, the connection between the connecting seat and the bag is achieved. The connecting seat, which can slide on the rod, allows the two connecting ears used to connect with the bag to adjust their positions to adapt to different bags. The connecting seat is equipped with rollers, which makes the sliding of the connecting seat smoother. At the same time, a limiting mechanism can limit one of the rollers, preventing the roller from rotating, thereby fixing the connecting seat. The two rollers are pressed tightly against the rod under the action of the clamping mechanism. Therefore, when the rollers cannot rotate, the rod and the rollers will be difficult to slide due to friction, thereby fixing the connecting seat. The cooperation between the fixing mechanism and the limiting mechanism can fix the connecting seat in any position on the rod.

[0007] Preferably, the connector is provided with a groove, and the connector lug is slidably connected within the groove. This invention utilizes the groove to allow the connector lug to slide, thereby enabling adjustment of the distance between the two connector lugs according to actual needs.

[0008] Preferably, the fixing mechanism is provided in two sets, with the two rollers in each set of the fixing mechanism respectively disposed on both sides of the two rods. This utility model achieves this by providing two sets of fixing mechanisms.

[0009] Preferably, the fixing mechanism includes a friction plate and a sliding rod. The friction plate is fixedly connected to the sliding rod, and the sliding rod is slidably connected to the connecting seat. The connecting seat is provided with a driving mechanism for driving the sliding rod to slide. This invention, through the driving mechanism, can push the sliding rod to press the friction plate tightly against the roller. The friction between the friction plate and the roller makes it difficult for the roller to rotate, thus limiting the roller's movement. The driving mechanism can then separate the friction plate from the roller, releasing the limiting effect.

[0010] Preferably, the driving mechanism includes a driving block and an elastic element. The elastic element is disposed between the slide rod and the connecting seat. The driving block is slidably connected to the connecting seat and abuts against the slide rod. Both the driving block and the slide rod have inclined surfaces at their contact points. The connecting seat is provided with a clamping mechanism for fixing the driving block. This invention utilizes the inclined surfaces on the driving block to drive the slide rod to slide when the driving block is pushed, thereby causing the friction plate to press tightly against the roller. After the friction plate is pressed against the roller, the clamping mechanism is a driving block clamp, which keeps the friction plate pressed against the roller. During the sliding process, the elastic element deforms. After the driving block is released, the slide rod will return to its original position under the elastic force of the elastic element, thus releasing the roller from its limit.

[0011] Preferably, the locking mechanism includes a pin and a second elastic element. The pin is slidably connected to the connecting seat, and the second elastic element is disposed between the pin and the connecting seat. The driving block has a socket for the pin to be inserted. This invention utilizes the second elastic element to align the pin with the socket on the driving block, allowing it to be inserted into the socket under the elastic force of the second elastic element, thereby fixing the driving block. Simultaneously, pulling the pin out of the socket releases the locking mechanism on the driving block.

[0012] Preferably, the clamping mechanism includes a connecting frame and a clamping bolt. The connecting frame is slidably connected to the connecting seat, the roller is rotatably connected to the connecting frame, and the clamping bolt is threadedly connected to the connecting seat, abutting against the connecting frame. This invention utilizes the threaded connection between the clamping bolt and the connecting seat, allowing the clamping bolt to push the connecting frame to slide when rotating, thereby causing the roller rotatably connected thereto to clamp onto the rod.

[0013] Preferably, each roller has an annular groove that matches the rod body, and the rod body is embedded in the annular groove. This invention utilizes the annular groove to increase the contact area between the rod body and the roller, thereby further increasing the friction.

[0014] Preferably, the friction pad surface is provided with a plurality of protrusions. This invention utilizes these protrusions to increase the surface roughness of the friction pad, thereby further increasing the frictional force between the friction pad and the roller.

[0015] In summary, the beneficial effects of this utility model are:

[0016] 1. The two connecting lugs used to connect to the bag can be adjusted to fit different bags by using a connecting lug that can slide on the rod.

[0017] 2. The connection seat can be fixed at any position on the rod by the cooperation of the fixing mechanism and the limiting mechanism.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0028] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0031] like Figure 1-2 As shown, a simple bag fastening rod includes a handle 1 and two rods 2. Both rods 2 are fixedly connected to the handle 1. Each rod 2 is provided with a connecting seat 3 for fixing to the bag. The connecting seat 3 is provided with two connecting ears 4 for connecting to the bag. Each connecting ear 4 is provided with a through hole 5. The connecting seat 3 is slidably connected to the two rods 2. A fixing mechanism for fixing the connecting seat 3 is provided inside the connecting seat 3. The fixing mechanism includes two rollers 6. The two rollers 6 are respectively provided on both sides of one of the rods 2. One roller 6 is rotatably connected to the connecting seat 3, and the connecting seat 3 is provided with a limiting mechanism for limiting the rotation of the roller 6. The other roller 6 is rotatably connected to the connecting seat 3 through a pressing mechanism. The two rollers 6 are pressed tightly onto the rod 2 by the pressing mechanism.

[0032] By adopting the above technical solution, the connecting seat 3 can be engaged with the threaded hole on the bag through the through hole 5 on the connecting ear 4. By passing a screw through the through hole 5 and threading it into the threaded hole of the bag, the connection between the connecting seat 3 and the bag is achieved. The connecting seat 3, which can slide on the rod 2, allows the two connecting ears 4 used to connect with the bag to adjust their positions to adapt to different bags. The connecting seat 3 is equipped with rollers 6, which makes the sliding of the connecting seat 3 smoother. At the same time, the limiting mechanism can limit one of the rollers 6, so that the roller 6 cannot rotate, thereby fixing the connecting seat 3. The two rollers 6 are pressed tightly against the rod 2 under the action of the pressing mechanism. Therefore, when the rollers 6 cannot rotate, the rod 2 and the rollers 6 will be difficult to slide due to friction, thereby fixing the connecting seat 3. Through the cooperation of the fixing mechanism and the limiting mechanism, the connecting seat 3 can be fixed at any position on the rod 2.

[0033] The connector 3 is provided with a groove 7, and the connector ear 4 is slidably connected within the groove 7. The groove 7 allows the connector ear 4 to slide, thereby allowing the distance between the two connector ears 4 to be adjusted according to actual needs.

[0034] The fixing mechanism consists of two sets, with two rollers 6 in each set positioned on either side of the two rods 2. This is achieved by setting up two sets of fixing mechanisms.

[0035] The fixing mechanism includes a friction plate 8 and a slide rod 9. The friction plate 8 is fixedly connected to the slide rod 9, and the slide rod 9 is slidably connected to the connecting seat 3. The connecting seat 3 is equipped with a drive mechanism to drive the slide rod 9 to slide. The drive mechanism can push the slide rod 9 to press the friction plate 8 tightly against the roller 6. The friction between the friction plate 8 and the roller 6 makes it difficult for the roller 6 to rotate, thereby limiting the movement of the roller 6. The drive mechanism can also separate the friction plate 8 from the roller 6 to release the limiting effect.

[0036] The driving mechanism includes a driving block 10 and an elastic element 11. The elastic element 11 is disposed between the slide rod 9 and the connecting seat 3. The driving block 10 is slidably connected to the connecting seat 3 and abuts against the slide rod 9. Both the driving block 10 and the slide rod 9 have inclined surfaces at their contact points. The connecting seat 3 is provided with a clamping mechanism for fixing the driving block 10. The inclined surfaces on the driving block 10 allow the slide rod 9 to slide when the driving block 10 is pushed, thereby causing the friction plate 8 to press tightly against the roller 6. After the friction plate 8 is pressed tightly against the roller 6, the clamping mechanism, consisting of a locking post on the driving block 10, keeps the friction plate 8 pressed against the roller 6. During the sliding process, the slide rod 9 causes the elastic element 11 to deform. After the driving block 10 is released, the slide rod 9 will reset under the elastic force of the elastic element 11, thus releasing the roller 6 from its limit.

[0037] The locking mechanism includes a pin 12 and an elastic element 13. The pin 12 is slidably connected to the connecting seat 3, and the elastic element 13 is disposed between the pin 12 and the connecting seat 3. The driving block 10 has a socket for the pin 12 to be inserted. By using the elastic element 13 to align the pin 12 with the socket on the driving block 10, the pin 12 can be inserted into the socket under the elastic force of the elastic element 13, thereby fixing the driving block 10. At the same time, by pulling the pin 12 out of the socket, the locking of the driving block 10 can be released.

[0038] The clamping mechanism includes a connecting frame 14 and a clamping bolt 15. The connecting frame 14 is slidably connected to the connecting seat 3, and the roller 6 is rotatably connected to the connecting frame 14. The clamping bolt 15 is threadedly connected to the connecting seat 3 and abuts against the connecting frame 14. The threaded connection between the clamping bolt 15 and the connecting seat 3 allows the clamping bolt 15 to push the connecting frame 14 to slide when it rotates, thereby causing the roller 6, which is rotatably connected to it, to clamp onto the rod 2.

[0039] Each roller 6 has an annular groove 16 that matches the rod 2, and the rod 2 is embedded in the annular groove 16. The annular groove 16 increases the contact area between the rod 2 and the roller 6, thereby further increasing the friction.

[0040] The friction plate 8 has several protrusions 17 on its surface. The protrusions 17 can increase the roughness of the surface of the friction plate 8, thereby further increasing the friction between the friction plate 8 and the roller 6.

[0041] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
