Description

Technical Field

[0001] The present invention relates to the technical field of luggage, and particularly to a rod handling device that facilitates going up and down stairs. Background Art

[0002] The pull - rod type luggage is a commonly used travel tool for people in the business and travel society. During the travel process, whether in stations, airports or other public places, stepped stairs are often encountered. If the luggage is relatively heavy and there is no elevator or the elevator is crowded, the conventional pull - rod suitcase cannot be pulled up along the stairs, and it is very laborious to carry it up. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a rod handling device that facilitates going up and down stairs.

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

Installation grooves are respectively opened at the lower positions on both sides of the outer wall of one side of the load - bearing frame, and fixing rods are welded at equal intervals on the inner walls on both sides in the width direction of the two installation grooves from top to bottom. The two ends of the fixing rods are alternately installed with rollers through bearings. The braking mechanism includes a brake plate and a roller brake pad arranged from inside to outside in the installation groove. The roller brake pad is located between the alternating roller group and the brake plate. Grooves adapted to the rollers are equidistantly opened on one outer wall of the roller brake pad, and triangular grooves are equidistantly distributed along the vertical direction on the other outer wall of the roller brake pad. Triangular brake blocks adapted to the triangular grooves are equidistantly arranged on the outer wall of the brake plate close to the triangular grooves. A brake lead is welded to the top of the brake plate.

[0006] Furthermore, two sleeves are welded on the inner wall of the bottom of the load - bearing frame, and the tops of the two sleeves are both connected with, and two damping hinges are connected with a "U" - shaped hollow handle. The load - bearing frame is provided with a card slot adapted to the hollow handle.

[0007] Furthermore, a through - hole is opened on the inner wall of the top of the middle section of the hollow handle, and a button is slidably connected to the inner wall of the through - hole. The bottom of the button is welded to the brake lead, and a micro - spring is welded to the inner wall of the bottom of the middle section of the hollow handle, and the top of the micro - spring is connected to the bottom of the button.

[0008] Further, traction amplification mechanisms are fixed on the inner wall of the load-bearing frame, the inner wall of the sleeve, and the inner wall of the hollow handle. The traction amplification mechanism includes a first pulley and a second pulley. The first pulley and the second pulley are coaxially connected, and the diameter of the first pulley is 2-3 times that of the second pulley. The brake lead wire is successively wound around the first pulley and the second pulley.

[0009] Further, support springs are welded to the four corners of the outer wall of the roller brake pad close to the brake plate, and the support springs are welded to the inner wall of the installation groove away from its opening. A traction spring is welded to the bottom of the brake plate, and the traction spring is welded to the bottom inner wall of the installation groove.

[0010] Further, the buffer mechanism includes spring pieces fixed to the inner wall of the installation groove away from its opening at equal distances by fixing bolts. The spring pieces are in an arc structure.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Through the alternating roller group, when the load-bearing frame topples onto the steps, it can prevent the top of the steps from being embedded between adjacent two rollers, enabling all rollers to contact the plane when placed on a plane. Different groups of rollers are mutually misaligned, reducing the amplitude of up and down fluctuations when the rollers contact the corner positions of the steps, so that each roller can smoothly slide over the step corners, avoiding the load-bearing frame from getting stuck on the steps;

[0013] 2. Through the brake mechanism and the traction amplification mechanism, when the sliding speed is too fast when going up and down the steps, by pressing the button, the brake lead wire can be pulled, so that the brake plate moves upward, the triangular brake block squeezes the roller brake pad, and the roller brake pad clamps the roller, making the roller slow down or stop rotating;

[0014] 3. The spring pieces on the buffer mechanism can play a buffer protection role for the alternating pulley group when the alternating pulley group is subjected to a large external force collision. Description of the Drawings

[0022] Referring to Figures 1-5 , a rod-type handling device convenient for going up and down stairs, comprising a load-bearing frame 1, an alternating roller group 3 installed on both sides of the outer wall of one side of the load-bearing frame 1, a braking mechanism installed on one side of the alternating roller group 3, and a buffer mechanism installed on one side of the braking mechanism. Installation grooves 2 are respectively opened at the lower positions on both sides of the outer wall of one side of the load-bearing frame 1. Fixed rods 4 are welded at equal distances from top to bottom on the inner walls on both sides in the width direction of the two installation grooves 2. The two ends of the fixed rods 4 are alternately installed with rollers 5 through bearings. The braking mechanism includes a brake plate 9 and a roller brake pad 7 arranged in sequence from inside to outside in the installation groove 2. The roller brake pad 7 is located between the alternating roller group 3 and the brake plate 9. Grooves 10 adapted to the rollers 5 are equidistantly opened on one outer wall of the roller brake pad 7. Triangular grooves 11 are equidistantly arranged in the vertical direction on the other outer wall of the roller brake pad 7. Triangular brake blocks 12 adapted to the triangular grooves 11 are equidistantly arranged on one outer wall of the brake plate 9 close to the triangular grooves 11. A brake lead wire 14 is welded to the top of the brake plate 9

[0023] In the present invention, two sleeves 6 are welded on the inner wall of the bottom of the load-bearing frame 1. The tops of the two sleeves 6 are both connected with two damping hinges 61, and the two damping hinges 61 are connected with a "U"-shaped hollow handle 62. The load-bearing frame 1 is provided with a slot 63 adapted to the hollow handle 62. A through hole is opened on the inner wall of the top of the middle section of the hollow handle 62, and a button 15 is slidably connected to the inner wall of the through hole. The bottom of the button 15 is welded to the brake lead 14. A micro spring 16 is welded on the inner wall of the bottom of the middle section of the hollow handle 62, and the top of the micro spring 16 is connected to the bottom of the button 15. Traction amplification mechanisms 19 are fixed on the inner wall of the load-bearing frame 1, the inner wall of the sleeve 6, and the inner wall of the hollow handle 62. The traction amplification mechanism 19 includes a first pulley 20 and a second pulley 21. The first pulley 20 and the second pulley 21 are coaxially connected.

The spring pieces 17 are arc-shaped structures.

[0024] When the load-bearing frame 1 topples over on the steps, the alternating roller group 3 can prevent the top of the steps from being embedded between two adjacent rollers 5, enabling all the rollers 5 to contact the plane when placed on a plane.
