Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, specifically relating to a high-strength pull rod for luggage. Background Technology

[0002] Bags and luggage are a general term for all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various types of rolling suitcases.

[0003] A high-strength trolley case according to CN201721885338.5 includes a case body with a trolley rod inside. The trolley rod has several reinforcing cavities recessed into it, evenly distributed along its circumference. A base is also provided on the trolley rod, fitted with several positioning grooves containing positioning pads that fit snugly against the case body. A reinforcing seat is also fitted onto the trolley rod in the middle. The trolley rod has a buffer layer and a support layer. The support layer is located on the outer side of the trolley rod and is made of aluminum alloy. The buffer layer is located on the inner side of the trolley rod and is made of high-pressure foamed plastic. This high-strength trolley case improves the strength of the trolley rod.

[0004] The aforementioned high-strength trolley bags still have some defects. Although there are reinforcing cavities and reinforcing seats on the trolley, there are only two trolleys, resulting in low reinforcement strength. Under heavy loads, the trolleys may still break, requiring repairs and reducing the lifespan of the bags. Therefore, we propose a high-strength trolley for bags. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength pull rod for bags, in order to solve the problem mentioned in the background art that although the pull rod is provided with a reinforcing cavity and a reinforcing seat, there are only two pull rods, resulting in low reinforcement strength. Under large stress, the pull rod will still break, which requires the bag to be repaired and reduces the service life of the bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength pull rod for bags, comprising a base and a case body, wherein the base is slidably connected inside the case body, the base is provided with a plurality of positioning grooves, and positioning pads are provided in the positioning grooves, the positioning pads being in contact with the case body, two No. 1 pull rods are fixedly connected to one end of the top of the base, and a No. 1 handle is fixedly connected to the top of the No. 1 pull rod, and two No. 2 pull rods are movably connected to the other end of the top of the base, the tops of the No. 2 pull rods being fixedly connected to the No. 2 handles, the No. 1 pull rods are provided with snap-fit ​​grooves inside, and snap-fit ​​blocks are fixedly connected to the front of the No. 2 pull rods, the snap-fit ​​blocks being adapted to the snap-fit ​​grooves.

[0007] Preferably, a sliding groove is provided at the rear top of the base, and a slider is fixedly connected to the bottom of the second pull rod, the slider being movably connected inside the sliding groove.

[0008] Preferably, a limiting groove is provided on both sides of the inner side of the slide groove, and a limiting block is fixedly connected to both sides of the slider, with the limiting block being movably connected inside the limiting groove.

[0009] Preferably, the front of the snap-fit ​​block is provided with a groove, and a hook is rotatably connected inside the groove.

[0010] Preferably, one end of the first pull rod on the left is fixedly connected to a first connecting strap, and one end of the first pull rod on the right is fixedly connected to a second connecting strap, wherein the first connecting strap and the second connecting strap are movably connected.

[0011] Preferably, both the first connecting strip and the second connecting strip are made of elastic material. The bottom of the first connecting strip is fixedly connected to a plug, and the bottom of the second connecting strip is fixedly connected to a slot. The plug and the slot are compatible.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By moving the two pull rods on the base to align them with the first pull rod, the locking blocks engage with the locking slots, thus locking the front and rear pull rods together. After engagement, the case can be moved by holding the first and second handles. The two pull rods, together with the locking blocks and locking slots, enhance the reinforcement strength, reduce the possibility of pull rod breakage, and extend the service life of the case.

[0014] 2. By rotating the hook to its position inside the groove and hanging items on the hook, the practicality of the pull rod is improved. Wrap the No. 1 and No. 2 connecting straps around the back and insert the plug into the slot to tie the two pull rods tightly, thereby improving the stability of the pull rod during use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a high-strength pull rod technical solution for bags: it includes a base 1 and a case body. The base 1 is slidably connected to the inside of the case body. The base 1 is provided with several positioning grooves 2, and positioning pads 3 are provided in the positioning grooves 2. The positioning pads 3 fit against the case body. Two first pull rods 4 are fixedly connected to one end of the top of the base 1. A first handle 5 is fixedly connected to the top of the first pull rod 4. Two second pull rods 6 are movably connected to the other end of the top of the base 1. A second handle 7 is fixedly connected to the top of the second pull rod 6. The first pull rod 4 is internally provided with There is a snap-fit ​​groove 8, and a snap-fit ​​block 9 is fixedly connected to the front of the second pull rod 6. The snap-fit ​​block 9 is adapted to the snap-fit ​​groove 8. Move the two positions of the second pull rod 6 on the base 1 so that the second pull rod 6 is close to the first pull rod 4. The snap-fit ​​block 9 is snapped into the inside of the snap-fit ​​groove 8, and the front and rear pull rods are snapped together.
