Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to a tourist backpack structure. Background Art

[0002] A backpack refers to a bag carried on the back, usually used to carry items such as office supplies, books, laptops, food, etc. needed by students, office workers, travelers, etc. in a convenient and comfortable way. It is made of leather, plastic, polyester, canvas, nylon, cotton and linen, etc. As people's living and consumption standards continue to improve, various backpacks have become indispensable items around people.

[0003] Most existing backpacks use soft cloth back pads or mesh back pads. When using the backpack, although most current backpacks are designed with an arc to leave a gap between the human back and the backpack, a large amount of heat will still accumulate between the human back and the backpack, causing the user's back to sweat due to heat, which in turn causes the clothes to be soaked. When the clothes are soaked, bacteria and mites will breed, causing skin allergies, and further causing skin itching and pain, which brings discomfort to people. Utility Model Content

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Embodiment 1

[0023] Combined with Figure 1 A travel backpack structure includes a bag body 1, two pairs of shoulder straps 2 are symmetrically arranged on the back of the bag body 1, and a pair of abdominal belts 3 are symmetrically arranged at the lower positions on both sides of the bag body 1. The ends of the upper and lower shoulder straps 2 and the left and right abdominal belts 3 are respectively connected with buckles 4 and sockets 5 that are clamped to each other, and the shoulder straps 2 and abdominal belts 3 are made of breathable material.

[0024] Combined with the above structure, the bag body 1 is carried on the human body through two pairs of shoulder straps 2 connected together by buckles 4 and sockets 5, and an abdominal belt 3 connected together by a pair of buckles 4 and sockets 5, so that the bag body 1 can be stably fixed on the human body, which is convenient for travelers to use.

[0025] Combined with Figure 1 and attached Figure 4 The back of the package body 1 is detachably connected with a heat removal plate 6, the back of the heat removal plate 6 is provided with a mounting groove 601, a heat removal blower 7 is installed in the mounting groove 601, a plurality of equidistant ventilation holes 602 are provided on the top wall of the mounting groove 601, a ventilation baffle 8 is installed at the opening of the mounting groove 601, a plurality of equidistant ventilation holes 801 are provided on the ventilation baffle 8, and a buffer pad 9 is symmetrically fixed at the upper and lower positions of the back of the heat removal plate 6.

[0026] In combination with the above structure, when the bag body 1 is carried on the user's back, the upper and lower pairs of cushion pads 9 contact the user's back, leaving a gap between the center of the heat removal plate 6 and the user's back. The heat removal blower 7, ventilation hole 1 602, and ventilation hole 2 801 cooperate to facilitate ventilation of the user's back, preventing a large amount of heat from accumulating between the human back and the backpack, causing the user's back to sweat due to heat, and causing the user to feel uncomfortable.

[0027] Combined with Figure 2 and attached Figure 3 A pair of connecting belts 10 are provided at the upper and lower positions of the back of the package body 1, and a plurality of connecting holes 1001 are provided on the connecting belts 10. A pair of connecting grooves 603 corresponding to the connecting belts 10 are provided on one side of the heat removal plate 6. Threaded holes 604 corresponding to the connecting holes 1001 are provided at the upper and lower ends of the connecting grooves 603. The upper and lower ends of the heat removal plate 6 are respectively threadedly connected with butterfly threaded rods 11 threadedly connected to the threaded holes 604 and passing through the connecting holes 1001.

[0028] In combination with the above structure, the heat removal plate 6 is connected to the connecting belt 10 of the package body 1 through the connecting groove 603 and the butterfly threaded rod 11, so that the heat removal plate 6 is easy to install and disassemble, and the heat removal plate 6 is easy to maintain. When the heat removal plate 6 is no longer needed, such as in winter, the heat removal plate 6 can be removed to reduce the weight.

[0029] Combined with Figure 4 The back of the cushion pad 9 is provided with an arc-shaped groove 901, and a breathable mesh 12 is fixed in the arc-shaped groove 901 to facilitate ventilation.

[0030] Combined with Figure 4 The heat removal fan 7 includes a mounting frame 13 mounted on the inner wall of the mounting groove 601, a motor 14 is mounted at the center of the mounting frame 13, and the output end of the motor 14 is connected to a plurality of blades 15 through the mounting frame 13. The motor 14 drives the plurality of blades 15 to rotate, which is convenient for ventilation.

[0031] The specific usage is as follows:

[0032] The bag body 1 is fixed to the back of the human body by two pairs of shoulder straps 2 connected by buckles 4 and clamps 5, and an abdominal belt 3 connected by a pair of buckles 4 and clamps 5. At this time, the upper and lower pairs of cushion pads 9 contact the back of the user, so that there is a gap between the center of the heat removal plate 6 and the back of the user. The heat removal blower 7, the ventilation hole 1 602, and the ventilation hole 2 801 cooperate to blow air to the back of the user, thereby preventing a large amount of heat from accumulating between the back of the human body and the backpack, causing the back of the user to sweat due to heat, and causing the user to feel uncomfortable.

[0033] When the heat removal plate 6 is not needed, such as in winter or when the heat removal plate 6 needs to be maintained, the butterfly threaded rod 11 is rotated to disengage it from the connecting hole 1001 on the connecting belt 10, and the heat removal plate 6 can be removed.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
