[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-jamming luggage handle, comprising a frame, two bottom rods and a top rod symmetrically arranged on the frame, the top rod being located above the bottom rods, the bottom rods having a slot inside, the top rod being inserted into the slot, the bottom end of the top rod having a base that can rise and fall within the slot, the upper end of the frame having a positioning seat penetrated by the top rod, the positioning seat having multiple guide holes, the bottom end of the guide holes having a positioning shaft, a ball bearing rotatably connected to the positioning shaft, and the positioning shaft penetrating the center of the ball bearing;

[0006] The upper end of the frame is also provided with a protective cover, which is fixed to the upper end of the frame. The middle part of the protective cover is provided with a cavity through which the positioning seat passes, and the protective cover is provided with a feeding pipe.

[0007] To make the empty slot cleaner, the present invention is improved by providing a bottom block at the bottom end of the bottom rod, and the bottom block is threadedly connected to the bottom rod.

[0008] To improve the sealing performance of the ball bearing, the present invention includes an improvement in that a sealing sleeve is provided on the outer wall of the ball bearing.

[0009] Furthermore, an improvement of this utility model is that a sealing ring, which is penetrated by a top rod, is embedded in the top of the positioning seat.

[0010] Furthermore, an improvement of this utility model is that both the sealing sleeve and the sealing ring are made of rubber.

[0011] Furthermore, an improvement of this utility model is that a protective cap is provided on the top of the cover, the top end of the feeding tube is inserted into the interior of the protective cap, and the protective cap is threadedly connected to the feeding tube.

[0012] Compared with the prior art, this utility model provides a bag handle that is resistant to jamming, which has the following advantages:

[0013] By employing a unique lubrication structure—utilizing a feeding tube, guide holes, and ball bearings working in tandem—the push rod and positioning seat maintain excellent lubrication at all times. This significantly reduces friction during push rod extension and remarkably lowers the frequency of jamming, providing users with a smoother pull rod experience. Compared to traditional luggage pull rods lacking a lubrication mechanism, this greatly improves ease of use. Attached Figure Description

[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 1-4This utility model discloses an anti-jamming luggage handle, comprising a frame 1, on which two bottom rods 2 and a top rod 3 are symmetrically arranged. The top rod 3 is located above the bottom rods 2. The bottom rods 2 have a hollow groove 5, and the top rod 3 is inserted into the hollow groove 5. The bottom end of the top rod 3 is provided with a base 6 that can be raised and lowered within the hollow groove 5. The upper end of the frame 1 is provided with a positioning seat 12 through which the top rod 3 passes. The positioning seat 12 is provided with multiple guide holes 8. The bottom end of the guide holes 8 is provided with a positioning shaft 9. A ball bearing 10 is rotatably connected to the positioning shaft 9, and the positioning shaft 9 passes through the center of the ball bearing 10.

[0021] The upper end of the frame 1 is also provided with a cover 13, which is fixed to the upper end of the frame 1. The middle part of the cover 13 is provided with a cavity through which the positioning seat 12 passes. The cover 13 is provided with a feeding pipe 14.

[0022] Basic telescopic structure operation: Frame 1 is installed at a specific position on the bag as the overall support structure. When the user pulls the top rod 3, since the top rod 3 is inserted into the slot 5 in the bottom rod 2, and the bottom end of the top rod 3 is equipped with a base 6, the base 6 will rise and fall accordingly in the slot 5, thereby realizing the extension and retraction of the pull rod to meet the user's needs for different lengths of the bag pull rod.

[0023] Lubrication Mechanism Operation: A cover 13 is provided at the upper end of the frame 1, and a feeding pipe 14 is opened on the cover 13. The user can add lubricating oil to the inside of the cover 13 through the feeding pipe 14. The cover 13 has a cavity in the middle through which the positioning seat 12 passes, and the positioning seat 12 has multiple guide holes 8. When lubricating oil is added to the cover 13, it will flow into each guide hole 8. At the bottom of the guide hole 8, the positioning shaft 9 is rotatably connected to the ball 10, and the positioning shaft 9 passes through the center of the ball 10. The lubricating oil will adhere to the ball 10 at the bottom of the guide hole 8. As the push rod 3 is pulled, the ball 10 rolls, and the lubricating oil will be transferred from the ball 10 to the outer wall of the push rod 3, thereby forming a lubricating film between the push rod 3 and the positioning seat 12, which plays a lubricating role.

[0024] In this embodiment, the bottom end of the bottom rod 2 is provided with a bottom block 4, and the bottom block 4 is threadedly connected to the bottom rod 2.

[0025] The bottom end of the bottom rod 2 is connected to the bottom block 4 by a thread, which helps to prevent debris from entering the empty groove 5, keep the inside of the empty groove 5 clean, and avoid debris from interfering with the lifting and lowering movement of the top rod 3 in the empty groove 5.

[0026] In this embodiment, a sealing sleeve 11 is provided on the outer wall of the ball 10, and a sealing ring 16 that is penetrated by the top rod 3 is inlaid on the top of the positioning seat 12. Both the sealing sleeve 11 and the sealing ring 16 are made of rubber.

[0027] The outer wall of the ball bearing 10 is provided with a sealing sleeve 11, and the top of the positioning seat 12 is inlaid with a sealing ring 16 that is penetrated by the push rod 3, and both are made of rubber. The sealing sleeve 11 and the sealing ring 16 can effectively prevent dust, moisture and other impurities from entering, ensuring the normal rotation of the ball bearing 10 and the effective retention of lubricating oil on the one hand, and preventing impurities from adversely affecting the sliding between the push rod 3 and the positioning seat 12 on the other hand.

[0028] In this embodiment, a protective cap 15 is provided above the cover 13, the top end of the feeding tube 14 is inserted into the interior of the protective cap 15, and the protective cap 15 is threadedly connected to the feeding tube 14.

[0029] A protective cap 15 is provided on the top of the cover 13. The top of the feeding pipe 14 is inserted into the protective cap 15 and the two are threaded together. The protective cap 15 can prevent external impurities from entering the cover 13 from the feeding pipe 14 and affecting the normal operation of the lubrication system.

[0030] The design of the sealing sleeve 11 and sealing ring 16, especially the use of rubber material, provides excellent sealing performance and effectively blocks impurities such as dust and moisture. This not only protects the rotational flexibility of the ball bearing 10 and the performance of the lubricating oil, but also prevents impurities from entering between the push rod 3 and the positioning seat 12, ensuring the stability and reliability of the overall tie rod structure and further reducing jamming problems caused by impurities.
