Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] See also Figure 1-7 The present invention provides a technical solution: an epidemic prevention backpack, comprising a main backpack body 1, a bag cover 8 sewn to the top of the main backpack body 1, a secondary backpack body 2 integrally connected to the bottom of the main backpack body 1 via a cushioning sleeve 3, a hanging mechanism 4 adjustably connected to the inner cavity of the main backpack body 1 via a receiving mechanism 7, the hanging mechanism 4 extends to one side of the bottom side of the secondary backpack body 2, a supporting mechanism 6 fixedly connected to the bottom of the secondary backpack body 2, and a shielding mechanism 5 for shielding an enclosed space detachably connected to the bottom of the supporting mechanism 6;

[0041] The shielding mechanism 5 includes a shielding compression cover 501, and both sides of the shielding compression cover 501 are fixedly connected to the limiting frame 502.

The limiting frame 502 is a flexible plastic frame, and both sides of the limiting frame 502 are fitted with both sides of the support mechanism 6 through Velcro 503.

[0042] The specific implementation method is as follows: when the medical staff carrying the main backpack body 1 needs to perform emergency sampling, in order to shield the space near the sampling area, the shielding compression cover 501 can be moved out by pulling the Velcro 503 sewn on both sides of the support seat 601 to separate. At this time, the relative distance between adjacent hanging seats 504 can be expanded by twisting the adjusting screw rod 506, and the relative expansion of the limiting frame 502 with compressed edges can be controlled. At this time, the limiting frame 502 can be fully expanded.

Through the design of the sliding rod 706, the sliding rod 706 can be more heated by sliding in the sliding hole, which can improve the sleeve The stability of the movement of the seat 708 can avoid the energy absorption and abutment effect caused by the deflection of the socket 708. The two ends of the sliding rod 706 are fixedly connected to the socket 708. One side of the socket 708 is fixedly connected to a clamp 709. The clamp 709 is sleeved on the outer wall of the hanging rod 401. A screw hole is provided on the top of the clamp 709. The inner thread of the screw hole is connected to a fixing bolt 710. The fixing bolt 710 can ensure the abutment and energy absorption stability with the outer wall of the hanging rod 401 through the bolt, which is convenient for controlling and adjusting the processing effect. The fixing bolt 710 is connected to the hanging rod 401 top fit, the outer wall of the slide bar 706 is provided with a plurality of magnetic rings 707, the magnetic ring 707 is a permanent magnet, which can ensure the energy absorption effect of magnetic repulsion, and the magnetic rings 707 on both sides are respectively fitted with one side of the inner cavity of the insertion seat 705 and the sleeve seat 708, the receiving mechanism 7 also includes a connecting seat 704 fixedly connected to one side of the insertion seat 705, one side of the connecting seat 704 is fixedly connected to the abutment block 702, and both sides of the bottom of the abutment block 702 are fixedly connected to the dispersion block 703, and the connecting seat 704 is slidably connected to the main backpack body 1 At the opening on one side of the cavity, a connecting plate 701 is fixedly connected between the abutment blocks 702 on both sides. The connecting plate 701 can ensure the energy absorption abutment effect by abutting on the inner side of the main backpack body 1. The connecting plate 701 is fixedly connected to one side of the inner cavity of the main backpack body 1. A supporting vertical plate 712 is fixedly connected to the bottom of the connecting plate 701. Support ribs 711 are fixedly connected on both sides of the supporting vertical plate 712. The abutment block 702 is a flexible plastic component. The flexible abutment block 702 can ensure the abutment support effect, and the abutment block 702 fits well with one side of the inner cavity of the main backpack body 1.

[0044] The specific implementation method is as follows: after the main backpack body 1 is worn through the bag strap 404 on one side, the shaking impact force generated by the human body movement can drive the connecting plate 701 to abut through the rear abutment block 702 and the dispersion energy of the dispersion block 703 through the movement of the main backpack body 1. The kinetic energy is fully slid outside the slide rod 706 through the rear insertion seat 705. The movement of the insertion seat 705 can drive the magnetic ring 707 on the bottom side to move downward, and the dispersion block 703 can improve the circular dispersion treatment to improve the dispersion energy effect. The magnetic repulsion between the multiple magnetic rings 707 can fully offset the relative impact force of the front sleeve seat 708 and the insertion seat 705, so that it can perform efficient abutment when the main backpack body 1 vibrates, thereby effectively avoiding the adverse effects of the backpack movement impact reaction force on the user caused by more intense exercise. The magnetic ring 707 through the permanent magnet ensures the continuous force on the energy absorption effect to meet the processing needs. At the same time, the clamp 709 can achieve full connection with the outside of the hanging rod 401 through its own elastic force, thereby improving the assembly speed and safety of the hanging sleeve 402 and the bottom bag strap 404. At the same time, the hanging sleeve 402 can adjust the relative spacing width of the strap by hanging outside the hanging rod 401, which is also conducive to replacing the appropriate bag strap 404. At the same time, the bag strap 404 can be assembled and hung with the waist belt through the hinge rod 603 on the front side of the baffle plate 604, and the bearing strength of the shoulder is reduced by the abutment force of the waist belt. At the same time, the friction between the shoulder bag strap 404 and the wearer's shoulders and back is reduced by the main backpack body 1 after energy absorption, thereby improving the adaptability of use. The designed support vertical plate 712 and support rib plate 711 can improve the full abutment and pressure distribution on the back.

[0045] See also Figure 2-4 The support mechanism 6 includes a support seat 601, and the support seat 601 is fixedly connected to the bottom of the secondary backpack body 2. Both sides of the inner cavity of the support seat 601 are fixedly connected with slide rails, and the inner cavity of the slide rails is slidably connected with sliders, and a supporting slide 602 is fixedly connected between the sliders on both sides. One side of the supporting slide 602 is fixedly connected with a blocking plate 604, and the blocking plate 604 is more stable by sliding in the slide rail through the rear side slider, which can prevent the blocking plate 604 from shaking and deviating. The blocking plate 604 is in contact with one side of the support seat 601, and the blocking plate 604 is fixedly connected to the inner cavity of the slide rails. There are grooves at both ends of one side, and the inner cavity of the groove is fixedly connected to a hinge rod 603. The hinge rod 603 can improve the hanging effect on the end of the belt through the rod-shaped setting. The hinge rod 603 is mounted on the external belt. The four corners of the bottom of the load-bearing slide 602 are provided with load-bearing grooves, and the inner cavity of the load-bearing groove is hinged with a telescopic support leg 605 through a hinge block. The bottom of the telescopic support leg 605 is fixedly connected to a friction pad 606. Rollers are fixedly connected to both sides of the outer walls of the main backpack body 1 and the auxiliary backpack body 2, and the rollers on both sides are limitedly bound by binding belts.

[0046] The specific implementation method is as follows: when the storage space equipment in the main backpack body 1 is used for quarantine sampling, the rear side load-bearing slide 602 can be driven to slide in the support seat 601 by pulling the blocking plate 604, and the load-bearing slide 602 can be moved to the front end of the support seat 601. At the same time, after the telescopic support leg 605 rotates around the hinge block, the telescopic support leg 605 is vertically fixed to the ground. At this time, the friction pad 606 can be fully contacted and fixed with the ground by pulling the telescopic support leg 605 and fixing it with a pin rod on one side. At this time, the user can support the ground by sitting on the top of the load-bearing slide 602. The secondary backpack body 2 and the main backpack body 1 are designed so as to effectively reduce the discomfort caused to the user by standing for a long time to collect things. The secondary backpack body 2 and the main backpack body 1 can be opened or closed by the zipper openings on one side of the secondary backpack body 2 and the main backpack body 1, and the independent spaces of the secondary backpack body 2 and the main backpack body 1 can be set to realize the separation and placement of the front and back utensils. The buffer sleeve 3 between the secondary backpack body 2 and the main backpack body 1 can be tied to the sliding roller on one side by a binding belt to meet the requirements of regulating the accommodation distance and the inner cavity between the secondary backpack body 2 and the main backpack body 1.

[0047] Working principle: When in use, after the main backpack body 1 is worn through the bag body strap 404 on one side, the shaking impact force generated by the human body movement drives the connecting plate 701 through the abutment of the rear abutment block 702 and the dispersion energy of the dispersion block 703, and the kinetic energy is fully slid outside the slide rod 706 through the rear insertion seat 705. The movement of the insertion seat 705 drives the magnetic ring 707 on the bottom side to move downward. The magnetic repulsion between the multiple magnetic rings 707 fully offsets the relative impact force of the front sleeve seat 708 and the insertion seat 705. The clamp 709 is fully connected to the outside of the hanging rod 401 through its own elastic force. The bag body strap 404 is assembled and hung with the belt through the hinged rod 603 on the front side of the blocking plate 604;

[0048] When the medical staff carrying the main backpack body 1 performs emergency sampling, they pull the Velcro 503 to separate the Velcro 503 sewn on both sides of the support seat 601, and then move the shielding compression cover 501 out. Then, by twisting the adjusting screw rod 506 to expand the relative distance between the adjacent hanging seats 504, the limiting frame 502 with the compressed edge is controlled to expand relative to each other. After the limiting frame 502 on the top side is fully expanded and pulled upward, the compressed part of the shielding compression cover 501 is expanded and expanded by the movement of the limiting frame 502. The expanded shielding compression cover 501 accommodates medical staff to enter, and the shielding of the shielding compression cover 501 blocks external droplets and aerosol viruses, thereby shielding the space near the sampling area.

[0049] By using the storage space equipment in the main backpack body 1 for quarantine sampling, the rear side load-bearing slide 602 is driven to slide in the support seat 601 by pulling the blocking plate 604, and the load-bearing slide 602 moves to the front end of the support seat 601, and the telescopic support leg 605 is rotated around the hinge block, and the telescopic support leg 605 is vertically fixed to the ground. This is done by pulling the telescopic support leg 605 and fixing the friction pad 606 with full contact and fixation with the ground through a pin rod on one side. The user sits on the top of the load-bearing slide 602 for carrying and use, and the opening or closing of the sub-backpack body 2 and the main backpack body 1 on both sides is controlled by the zipper opening on one side of the sub-backpack body 2 and the main backpack body 1. The separate placement of the front and rear instruments is achieved by setting the independent space of the sub-backpack body 2 and the main backpack body 1, and the buffer sleeve 3 between the sub-backpack body 2 and the main backpack body 1 is tied to the one side sliding roller by a binding belt.
