Description
Technical Field
[0001] The utility model relates to the technical field of travel bags, in particular to a high-strength, low-noise, shock-proof travel bag. Background Art
[0002] Travel luggage refers to boxes and bags used to carry items for travel or tourism. According to different needs and uses, travel luggage can be divided into many types, including suitcases, trolley cases, backpacks, handbags, etc. Suitcases (also called suitcases or trolley cases) are commonly used when traveling, usually used to store clothes, personal care products and souvenirs. Suitcases have two structural forms: hard and soft. They are mostly rectangular in shape and equipped with pull rods and rollers for easy movement. Early suitcases were mostly made of wood or other heavy materials, but with the popularity of air travel, modern suitcases are mostly made of lightweight hard plastic or cloth materials;
[0003] The shock-absorbing function of travel luggage can effectively reduce the damage to the internal items of the suitcase caused by bumps and vibrations during transportation. Conventional travel luggage simply uses the cushioning pads on the universal wheels for cushioning. However, the cushioning pads on the universal wheels will age over time and their cushioning performance will drop sharply. Utility Model Content
[0004] The purpose of the utility model is to provide a high-strength, low-noise, shock-proof travel bag to solve the above problems.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-strength, low-noise, and shockproof travel bag, comprising:
[0006] A travel case shell having a buffer structure, the buffer structure comprising a connecting frame, a support rod, a bracket, a threaded rod, a chuck, and a spring;
[0007] The connecting frame is U-shaped, and the outer side of the connecting frame is in contact with the outer side of the travel bag shell. The two ends of the bottom of the connecting frame are respectively connected to two brackets, and the brackets are fixed to the connecting frame as a whole. There are two pulleys, which are located between the two brackets, and a distance is set between the two pulleys.
[0008] A support rod is provided between the two connecting frames, and both ends of the support rod are fixedly connected to the connecting frames;
[0009] There is a limit frame on the outside of each pulley, and the bottom of each limit frame is rotatably connected to the pulley. A spring is fixedly connected to one side of each limit frame. The end of the spring away from the limit frame is fixedly connected to the gasket. One end of the threaded rod passes through the gasket and is embedded in the inside of the spring, and the chuck fits against the inner side of the gasket.
[0010] Preferably, a threaded hole is provided on the telescopic bracket, and the threaded rod passes through the threaded hole and is threadedly connected to the bracket. One end of the threaded rod has an integral fixed handle, and the handle is perpendicular to the threaded rod. The rotating handle controls the depth of the threaded rod embedded in the threaded hole. When the threaded rod is embedded in the threaded hole at a shallow depth, the chuck pulls the gasket, causing the spring to be stretched, thereby adjusting the initial tension of the spring to increase, and conversely, the initial tension of the spring becomes smaller. When the initial tension is large, the amplitude of the up and down vibration of the pulley is small, and the vibration of the luggage is large. When the initial tension is small, the amplitude of the up and down buffering of the pulley is large, and the vibration of the luggage is small, thereby completing the adaptive adjustment.
[0011] Preferably, a groove is provided at the center of the outer side of the pulley, a buffer pad is provided on the outer side of the pulley, and an integrally formed convex strip is provided on the inner side of the buffer pad. The convex strip is embedded in the inner side of the groove and engages with the pulley. The buffer pad can reduce the noise generated when the pulley rotates, and the buffer pad can be removed from the outer side of the pulley for easy replacement. If the buffer pad ages after long-term use, it can be replaced in time to ensure the shock absorption performance of the buffer pad.
[0012] Preferably, the top of the limiting frame has an integrally fixed pipe sleeve, which is sleeved on the outside of the support rod and rotatably connected to the support rod.
[0013] Preferably, the tops of both sides of the connecting frame are provided with symmetrical connecting blocks, one end of the connecting block is fixedly connected to the outer side of the travel bag shell, and the connection between the connecting frame and the connecting block is provided with a connecting shaft, through which the connecting frame is rotatably connected to the connecting block.
[0014] Preferably, two symmetrical elastic bands are provided on the outside of the travel bag shell near the top, and the bottoms of the elastic bands are provided with fixed hooks.
[0015] Preferably, the top of the travel bag shell has universal wheels, and the travel bag shell has a buckled travel bag cover, the bottom of the travel bag cover and the drawstring are both equipped with universal wheels, and the travel bag shell and the travel bag cover are made of ABS resin. The suitcase made of ABS has high strength and good toughness, so that the suitcase performs well in long-distance travel, especially when it needs to withstand a large impact.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The buffer pad can reduce the noise generated when the pulley rotates, and the buffer pad can be removed from the outside of the pulley for easy replacement. If the buffer pad ages after long-term use, it can be replaced in time to ensure the shock absorption performance of the buffer pad;
[0018] 2. When the pulley touches the ground, the spring end is pulled and deformed by force, thereby achieving the purpose of buffering. After the impact force is offset, the spring resets, thereby completing the subsequent shock absorption work. When the pulley is buffering, the limit frame moves in an arc around the outside of the support rod through the pipe sleeve, thereby reducing the left and right shaking caused by the pulley buffering;
[0019] 3. Rotate the handle to control the depth of the threaded rod embedded in the threaded hole. When the threaded rod is embedded in the threaded hole shallowly, the chuck pulls the gasket, causing the spring to be stretched, thereby increasing the initial tension of the spring. Conversely, the initial tension of the spring becomes smaller. When the initial tension is large, the amplitude of the up and down vibration of the pulley is small, and the vibration of the luggage is large. When the initial tension is small, the amplitude of the up and down buffering of the pulley is large, and the vibration of the luggage is small, thereby completing the adaptive adjustment.

[0027] See also Figure 1-3 , the utility model provides a technical solution: a high-strength, low-noise, shockproof travel bag, including;
[0028] The travel bag shell 100 has a buffer structure, which includes a connecting frame 300, a support rod 302, a bracket 303, a threaded rod 400, a chuck 402, and a spring 404;
[0029] The connecting frame 300 is U-shaped. The outer side of the connecting frame 300 is in contact with the outer side of the travel bag shell 100. The two ends of the bottom of the connecting frame 300 are connected to two brackets 303 respectively. The brackets 303 are fixed to the connecting frame 300 as a whole. There are two pulleys 500, which are located between the two brackets 303 and a distance is set between the two pulleys 500.
[0030] A support rod 302 is provided between the two connecting frames 300, and both ends of the support rod 302 are fixedly connected to the connecting frames 300;
[0031] There is a limit frame 403 on the outside of each pulley 500, and the bottom of each limit frame 403 is rotatably connected to the pulley 500. A spring 404 is fixedly connected to one side of each limit frame 403. The end of the spring 404 away from the limit frame 403 is fixedly connected to the gasket 405. One end of the threaded rod 400 passes through the gasket 405 and is embedded in the inside of the spring 404. The chuck 402 fits against the inner side of the gasket 405.
[0032] Furthermore, the telescopic bracket 303 is provided with a threaded hole 304, and the threaded rod 400 passes through the threaded hole 304 and is threadedly connected to the bracket 303. One end of the threaded rod 400 has an integral fixed handle 401, and the handle 401 is perpendicular to the threaded rod 400. The rotating handle 401 controls the depth of the threaded rod 400 embedded in the threaded hole 304. When the threaded rod 400 is embedded in the threaded hole 304 at a shallow depth, the chuck 402 pulls the gasket 405, so that the spring 404 is stretched by the force, thereby adjusting the initial tension of the spring 404 to increase. Conversely, the initial tension of the spring 404 decreases. When the initial tension is large, the amplitude of the up and down vibration of the pulley 500 is small, and the vibration of the luggage is large. When the initial tension is small, the amplitude of the up and down buffering of the pulley 500 is large, and the vibration of the luggage is small, thereby completing the adaptive adjustment.
[0033] Furthermore, a groove is provided at the center of the outer side of the pulley 500, and a buffer pad 501 is provided on the outer side of the pulley 500. An integrally formed convex strip is provided on the inner side of the buffer pad 501, and the convex strip is embedded in the inner side of the groove and engaged with the pulley 500. The buffer pad 501 can reduce the noise generated when the pulley 500 rotates, and the buffer pad 501 can be removed from the outer side of the pulley 500 for easy replacement. If the buffer pad 501 ages after long-term use, it can be replaced in time to ensure the shock absorption performance of the buffer pad 501.
[0034] Furthermore, the top of the limiting frame 403 has an integrally fixed pipe sleeve 406 , which is sleeved on the outside of the support rod 302 and rotatably connected to the support rod 302 .
[0035] Furthermore, there are symmetrical connecting blocks 301 on the top of both sides of the connecting frame 300, one end of the connecting block 301 is fixedly connected to the outside of the travel bag shell 100, and there is a connecting shaft at the connection between the connecting frame 300 and the connecting block 301, and the connecting frame 300 is rotatably connected to the connecting block 301 through the connecting shaft.
[0036] Furthermore, two symmetrical elastic bands 200 are provided on the outside of the travel bag shell 100 near the top, and the bottom of each elastic band 200 has a fixedly connected hook 201.
[0037] Furthermore, the top of the travel bag shell 100 has a universal wheel 103, and the travel bag shell 100 has a buckled travel bag cover 101, and the bottom of the travel bag cover 101 and the drawstring 102 are both equipped with universal wheels 103, and the travel bag shell 100 and the travel bag cover 101 are made of ABS resin. The suitcase made of ABS has high strength and good toughness, so that the suitcase performs well in long-distance travel, especially when it needs to withstand a large impact.
[0038] Working principle: When in use, the connecting frame 300 is rotated through the connecting shaft and the connecting block 301, so that the pulley 500 at the bottom of the connecting frame 300 moves to the bottom of the suitcase shell 100, so that the pulley 500 contacts the ground, and the bottom of the suitcase shell 100 contacts the middle of the connecting frame 300, so that the suitcase is lifted by the connecting frame 300. When the pulley 500 contacts the ground, it is cushioned by the buffer pad 501 on the outside of the pulley 500, and the buffer pad 501 can reduce the noise generated when the pulley 500 rotates. The buffer pad 501 is sleeved on the outside of the pulley 500 and can be removed for easy replacement. If the buffer pad 501 ages after long-term use, it can be replaced in time to ensure the shock absorption performance of the buffer pad 501.
[0039] Furthermore, when the pulley 500 contacts the ground, the end of the spring 404 is pulled and deformed by the force, thereby achieving the purpose of buffering. After the impact force is offset, the spring 404 returns to its original position, thereby completing the subsequent shock absorption work. When the pulley 500 is buffering, the limit frame 403 moves in an arc around the outer side of the support rod 302 through the pipe sleeve 406, thereby reducing the left and right shaking caused by the pulley 500 during the buffering.
[0040] Furthermore, the handle 401 is rotated to control the depth of the threaded rod 400 embedded in the threaded hole 304. When the threaded rod 400 is embedded in the threaded hole 304 to a shallow depth, the chuck 402 pulls the gasket 405, causing the spring 404 to be stretched, thereby increasing the initial tension of the spring 404. Conversely, the initial tension of the spring 404 decreases. When the initial tension is large, the amplitude of the up and down vibration of the pulley 500 is small, and the vibration of the luggage is large. When the initial tension is small, the amplitude of the up and down buffering of the pulley 500 is large, and the vibration of the luggage is small, thereby completing the adaptive adjustment.
[0041] Furthermore, when the device is not in use, the connecting frame 300 is flipped upwards, and the elastic band 200 is pulled to extend the elastic band 200, and the hook 201 at the bottom of the elastic band 200 is hung on the outside of the support rod 302 for tightening and limiting.
[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
