Technical Field
[0001] The utility model is applicable to the technical field of plastic woven bags, in particular to a waterproof and fresh-keeping plastic woven bag. Background Art
[0002] At present, plastic woven bags, also known as snakeskin bags, are a type of plastic bags used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. They are extruded and stretched into flat wires, and then woven, knitted and made into bags. The woven bags are generally white or grayish white in color, non-toxic and odorless, and generally cause little harm to the human body. Woven bags have a wide range of uses.
[0003] However, when the woven bag is used for lifting, corresponding lifting ropes are provided at both ends of the outer side of the woven bag. However, due to the structural deficiencies of the lifting ropes themselves, the lifting length of the lifting ropes cannot be quickly adjusted. Therefore, when the woven bag is carried by hand for people with different usage habits, the height of the hand cannot be adjusted for suitability, which affects the comfort of carrying the woven bag. Therefore, we propose a waterproof and fresh-keeping plastic woven bag. Utility Model Content
[0004] The main purpose of the utility model is to provide a waterproof and fresh-keeping plastic woven bag, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A waterproof and fresh-keeping plastic woven bag, comprising a bag body, wherein a waterproof cushion layer is fixedly bonded to the inner wall surface of the bag body, hollow frames are fixedly installed on both ends of the outer top of the bag body, and an extrusion column is slidably installed through the middle end of each side of the hollow frame;
[0007] A first threading groove is provided inside both ends of the side of each hollow frame, a second threading groove is provided inside the middle end of each extrusion column, and the first threading groove and the second threading groove are in different horizontal planes, and a hand rope is slidably installed through the inner sides of each two groups of the second threading grooves, and the hand rope is slidably installed through the inner sides of the first threading grooves;
[0008] A pushing plate is fixedly installed between the outer end surfaces of each two groups of squeezing columns away from the bag body.
[0009] By adopting the above technical solution, by sliding the extrusion column into the interior of the hollow frame, and sliding the carrying rope between the hollow frame and the interior of the extrusion column, the two sides of the pulling rope can be pulled to adjust its length between the two groups of hollow frames, thereby facilitating the adjustment of the lifting height of the bag body according to the operator's hand carrying habits, thereby improving the user's carrying comfort of the bag body.
[0010] As an optional solution of the technical solution of the present application, a movable groove is opened inside the middle end of each side of the hollow frame, and the extrusion column penetrates and is slidably installed inside the movable groove.
[0011] By adopting the above technical solution, the movement stability of the extrusion column is ensured by the guiding sliding action of the movable groove on the extrusion column.
[0012] As an optional solution of the technical solution of the present application, each inner side of the hollow frame is movably fitted with a return spring, and the top end of the side of the return spring is movably fitted to the outer surface of the extrusion column.
[0013] By adopting the above technical solution, the reset processing of the extrusion column is guaranteed by the structural action of the reset spring, and the adjustment and limiting processing of the hand rope is guaranteed.
[0014] As an optional solution of the technical solution of the present application, limit stops are fixedly installed on the surfaces of both ends of the side edges of each of the hand ropes, and the diameter of the limit stops is larger than the inner diameter of the first threading groove.
[0015] By adopting the above technical solution, the hand rope can be adjusted and prevented from falling off by the structural action of the limit stopper.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. A waterproof and fresh-keeping plastic woven bag according to the technical solution of the present application, wherein a hollow frame is installed on both sides of the bag body, and the left and right sides of the carrying rope are passed through the first threading groove inside the hollow frame, and simultaneously passed through the second threading groove inside the extrusion column which can slide inside the hollow frame. When the extrusion column receives pressure from the outside and moves toward the inside of the hollow frame, the first threading groove and the second threading groove can be at the same horizontal position, so that the carrying rope will not be squeezed and is in a non-deformed state. Then, the two sides of the pulling rope can be pulled to adjust its length between the two groups of hollow frames, thereby facilitating the adjustment of the lifting height of the bag body according to the operator's carrying habits, thereby improving the carrying comfort of the bag body for the user.
[0018] 2. The technical solution of the present application is a waterproof and fresh-keeping plastic woven bag, which is equipped with a return spring sleeved inside a hollow frame. After the extrusion column is pressed to adjust the position of the second threading groove, the position of the extrusion column can be automatically and quickly restored to separate the second threading groove from the first threading groove. This can ensure that after the lifting length of the hand rope is adjusted, the hand rope is deformed by the resistance and the entire hand rope is limited to prevent the hand rope from sliding arbitrarily and affecting normal pulling use.
