Description

Technical Field

[0001] The utility model relates to the technical field of handles, in particular to a bag handle with a buffer structure. Background Art

[0002] Luggage and bags are equipped with handles for people to lift and pull the bags, and a torsion spring is provided between the handle and the handle connecting seat to facilitate the rotation and reset of the handle. However, most of the handles of luggage and bags currently on the market are not provided with a buffer structure. When the torsion spring drives the handle to rotate and reset, there is no buffer, which is easy to pinch people and is unsafe. Although there are some handle structures on the market that set damping oil between the handle and the handle connecting seat, the damping performance of the damping oil is easily affected by temperature and is unstable. The existing application number is CN202122610158.9, which is a luggage handle structure with buffering, including a handle body, a handle connecting seat and a damping rubber sleeve. The two ends of the handle body are rotatably connected to their respective corresponding handle connecting seats through a rotating shaft... A damping rubber sleeve is provided between the handle body and the handle connecting seat to achieve rotation damping buffering of the handle to prevent pinching of the hand. Compared with the existing damping oil buffer structure, it has the advantage of stable performance. However, after long-term use, the diameter of the damping rubber sleeve will change due to wear, resulting in a gap between the damping rubber sleeve mounting hole and the rotating shaft, and the contact area is reduced, affecting the ring groove effect. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings in the prior art that the damping rubber sleeve will change in diameter due to wear after long-term use, resulting in a gap between the damping rubber sleeve mounting hole and the rotating shaft, reducing the contact area and affecting the effect of the ring groove, and proposing a luggage handle with a buffer structure.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Preferably, the sliding limiting structure includes a T-shaped groove and a T-shaped slider. A T-shaped groove is provided in the arc groove on the top of the mounting block. The bottoms of several fixed damping rings are integrally formed with a T-shaped slider, and the T-shaped slider is slidably arranged in the T-shaped groove.

[0007] Preferably, the transmission limiting structure includes an axial slide groove and a slider. A plurality of axial slide grooves arranged in a circular array are opened on the outer wall of the rotating shaft. The inner walls of the plurality of rotating damping rings are integrally formed with a plurality of sliders, and the plurality of sliders are respectively slidably arranged in the plurality of axial slide grooves.

[0008] Preferably, the extrusion device includes an extrusion screw, a pair of end surfaces of the handlebar connecting seats away from each other are provided with threaded holes, and the extrusion screws are threadedly inserted into the threaded holes, and one end of the extrusion screw located inside the handlebar connecting seat abuts against the fixed damping ring.

[0009] Preferably, the reset device includes a torsion spring and a collar. The collar is fixedly provided on the outer wall of the rotating shaft. The torsion spring is sleeved on the outer wall of the rotating shaft. Both ends of the torsion spring are fixedly connected to the handle connecting seat and the collar respectively.

[0010] Preferably, the outer wall of the lower end of the handle connecting seat is integrally formed with a U-shaped flange plate, and the upper end surface of the U-shaped flange plate is provided with a plurality of mounting holes, screws are inserted into the mounting holes, and the lower ends of the screws are threadedly connected to the connecting strip.

[0011] The utility model proposes a luggage handle with a buffer structure, which has the beneficial effects of: compared with the inner and outer walls using a damping rubber sleeve, the side surfaces of the plurality of fixed damping rings and the rotating damping ring greatly increase the friction area and achieve better damping effect; and when a gap is generated between the rotating damping ring and the fixed damping ring due to long-term mutual friction loss, the rotating damping ring can be moved toward the fixed damping ring by rotating the extrusion screw and the fixed damping ring and the rotating damping ring can be squeezed to make them fit tightly, ensuring that the friction surfaces are in contact, and at the same time, the rotating damping ring can be moved left and right by rotating the extrusion screw to achieve the effect of adjusting the resistance.

[0020] Reference Figure 5 In order to prevent the fixed damping ring 8 from rotating but being able to slide left and right, the sliding limiting structure includes a T-shaped groove 13 and a T-shaped slider 16. A T-shaped groove 13 is opened in the arc groove at the top of the mounting block 10, and the bottoms of several fixed damping rings 8 are integrally formed with a T-shaped slider 16, and the T-shaped slider 16 is slidably set in the T-shaped groove 13.

[0021] Reference Figure 5 In order to enable the rotation damping ring 9 to rotate with the rotating shaft 5 and slide left and right on the rotating shaft 5, the transmission limiting structure includes an axial slide groove 14 and a slider 15. A plurality of axial slide grooves 14 arranged in a circumferential array are opened on the outer wall of the rotating shaft 5, and a plurality of sliders 15 are integrally formed on the inner walls of the plurality of rotation damping rings 9, and the plurality of sliders 15 are respectively slidably arranged in the plurality of axial slide grooves 14.

[0022] Reference Figure 2 In order to squeeze the rotating damping ring 9 and the fixed damping ring 8 to make them fit together when a gap is generated due to long-term mutual friction and loss, and to adjust the resistance by adjusting the extrusion force, the extrusion device includes an extrusion screw 6, and a pair of handlebar connecting seats 2 are provided with threaded holes on the end faces away from each other, and the extrusion screws 6 are threadedly inserted into the threaded holes, and one end of the extrusion screw 6 located inside the handlebar connecting seat 2 abuts against the fixed damping ring 8.

[0023] Reference Figure 4 In order to make the rotating shaft 5 automatically rotate after being loosened and drive the handle body 3 to rotate downward and fit vertically to the surface of the luggage, the reset device includes a torsion spring 11 and a ring 12. The outer wall of the rotating shaft 5 is fixed with a ring 12, and the outer wall of the rotating shaft 5 is sleeved with a torsion spring 11, and the two ends of the torsion spring 11 are fixedly connected to the handle connecting seat 2 and the ring 12 respectively.

[0024] Reference Figure 4 In order to fix the handle connecting base 2 on the connecting strip 1, and thus install the handle structure on the luggage, a U-shaped flange plate 4 is integrally formed on the outer wall of the lower end of the handle connecting base 2. A plurality of mounting holes 7 are opened on the upper end surface of the U-shaped flange plate 4. Screws are inserted into the inside of the mounting holes 7, and the lower ends of the screws are threadedly connected to the connecting strip 1.

[0025] Working principle: After the handle body 3 is released, the torsion spring 11 rotates and resets, and the handle body 3 is buffered by the friction between the rotating damping ring 9 that can rotate with the handle body 3 and the rotating shaft 5 and the fixed damping ring 8 that cannot rotate. When a gap is generated between the rotating damping ring 9 and the fixed damping ring 8 due to long-term mutual friction loss, the extrusion screw 6 is rotated to move it toward the fixed damping ring 8 and squeeze the fixed damping ring 8 and the rotating damping ring 9 to make them fit tightly, and the extrusion screw 6 is rotated to move it left and right, thereby adjusting the extrusion force on the fixed damping ring 8, and thus achieving the effect of adjusting the resistance by adjusting the pressure between the fixed damping ring 8 and the rotating damping ring 9.

[0026] Compared with the inner and outer walls of the damping rubber sleeve, the side surfaces of several fixed damping rings 8 and rotating damping rings 9 greatly increase the friction area and achieve better damping effect. When a gap is generated between the rotating damping ring 9 and the fixed damping ring 8 due to long-term mutual friction loss, the extrusion screw 6 is rotated to move the rotating damping ring 8 toward the fixed damping ring 8 and squeeze the fixed damping ring 8 and the rotating damping ring 9 to make them fit tightly, ensuring that the friction surfaces are in contact. At the same time, the extrusion screw 6 can be rotated to move the rotating damping ring 8 left and right to achieve the effect of adjusting the resistance.
