Description

Technical Field

[0001] The utility model relates to the technical field of packaging barrels, in particular to a packaging barrel provided with a discharging pipe limiting structure. Background Art

[0002] Most liquid chemical products have a pungent odor or are easy to volatilize. Generally, they need to be stored or transported in packaging barrels. The current packaging barrels include stainless steel packaging barrels, titanium packaging barrels, etc., which are equipped with discharge pipes. The packaging barrels are also divided into different sizes according to the model. For packaging barrels with larger volume and deeper depth, the discharge pipes used with them will be relatively slender. When the length of the discharge pipe is relatively long, its overall rigidity will deteriorate, and the end of the discharge pipe extending into the groove at the bottom of the packaging barrel will easily shake, which can easily cause scratches on the lower end of the discharge pipe and the bottom surface of the inner cavity of the packaging barrel, thereby affecting the product quality.

[0003] After searching, it is found that the Chinese publicly authorized patent "Packaging barrel with a discharge pipe limiting structure" has a publication number of "CN212074796U". This patent has a limit frame fixedly connected to the bottom of the packaging barrel body to limit the lower end of the discharge pipe. For a relatively long discharge pipe, the limit frame limits the end of the discharge pipe that extends to the bottom of the inner cavity of the packaging barrel and no longer shakes, thereby avoiding the shaking of the lower end of the discharge pipe and causing scratches on the lower end of the discharge pipe itself and the bottom surface of the inner cavity of the packaging barrel. Quality problems such as scratches.

[0004] However, in the production process of the above device, each packaging barrel must be matched with a corresponding discharge pipe and a limiting structure, which undoubtedly increases the production cost.

[0005] Therefore, a packaging barrel provided with a discharging pipe limiting structure is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a packaging barrel with a discharge pipe limiting structure in order to solve the above-mentioned problem, thereby improving the problem of high production cost of the device in the comparative case.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme. A packaging barrel provided with a discharge pipe limiting structure comprises: a packaging barrel body, a discharge pipe is provided at the top of the packaging barrel body, the bottom end of the discharge pipe penetrates into the interior of the packaging barrel body, and a limiting structure is provided at the top of the packaging barrel body; wherein the limiting structure comprises a threaded connector fixedly connected to the top of the packaging barrel body and sleeved on the surface of the discharge pipe, an external thread is provided on the surface of the discharge pipe, a threaded sleeve is threadedly connected to the surface of the discharge pipe, a movable sleeve is slidably provided on the surface of the threaded sleeve, a locking sleeve is rotatably connected to the bottom end of the movable sleeve, the inner wall of the locking sleeve is threadedly connected to the threaded connector, a limiting component is provided inside the packaging barrel body, a sealing ring is provided at the bottom of the threaded sleeve, and the sealing ring is made of corrosion-resistant rubber The material component is a rotating ring fixedly connected to the bottom of the movable sleeve, and an annular groove is provided on the top of the locking sleeve. The rotating ring is rotatably connected to the inner wall of the annular groove. When the material inside the packaging barrel body needs to be discharged, the discharge pipe is inserted into the packaging barrel body through the threaded connector. When the bottom of the discharge pipe contacts the inner bottom wall of the packaging barrel body, the threaded sleeve is rotated to move downward until the bottom of the threaded sleeve contacts the top of the threaded connector, and then the movable sleeve is pulled down to drive the locking sleeve to move downward, and then the locking sleeve is rotated to make it threadedly connected to the surface of the threaded connector. Compared with the comparative case, after the material inside the packaging barrel body is discharged, the device can be dismantled, so that the device can be recycled and only one set is needed, which effectively reduces the production cost of the packaging barrel.

[0008] Preferably, the limiting assembly includes two limiting plates, which are fixedly connected to the inner bottom wall of the packaging barrel body, and the top of the limiting plate is fixedly connected to the inner top wall of the packaging barrel body, and the opposite sides of the two limiting plates are fixedly connected to limiting strips, and the surface of the discharge pipe is provided with two limiting grooves, and the limiting strip slides on the inner wall of the limiting groove, and the top of the threaded connector is provided with two pointing arrows, which are symmetrically distributed. When installing the discharge pipe, the two pointing arrows are respectively aligned with the two limiting grooves on the discharge pipe. The pointing arrows facilitate the installation of the discharge pipe and the alignment of the limiting groove and the limiting strip. Then, the discharge pipe is installed. When the discharge pipe moves downward, it will slide on the surface of the limiting strip through the limiting groove. At this time, the discharge pipe will be located between the two limiting plates, so that the discharge pipe can be limited to prevent the discharge pipe from shaking in the packaging barrel body.

[0009] Preferably, the surface of the threaded sleeve is provided with annularly distributed locking grooves, the surface of the movable sleeve is provided with annularly distributed screws, the ends of the screws sequentially penetrate into the interior of the movable sleeve and the locking grooves, the ends of the screws are provided with resistance increasing plates, the resistance increasing plates are made of wear-resistant rubber material, after the installation of the locking sleeve is completed, the resistance increasing plates are pressed against the inner wall of the locking groove by rotating the screws, thereby preventing the movable sleeve from rotating on the surface of the threaded sleeve.

[0010] Preferably, a circularly distributed buffer pad is provided at the bottom end of the discharge pipe. The buffer pad is made of corrosion-resistant rubber material. The buffer pad can prevent its bottom from causing damage to the inner bottom wall of the packaging barrel body when the discharge pipe is installed. At the same time, the grooves formed between the multiple buffer pads can prevent the material from entering the bottom of the discharge pipe.

[0011] The beneficial effects of the utility model are:

[0012] 1. When the material inside the packaging barrel body needs to be discharged, the discharge pipe is inserted into the packaging barrel body through the threaded connector. When the bottom of the discharge pipe contacts the inner bottom wall of the packaging barrel body, the threaded sleeve is rotated to move downward until the bottom of the threaded sleeve contacts the top of the threaded connector. Then, the movable sleeve is pulled down to drive the locking sleeve to move downward, and then the locking sleeve is rotated to make it threadedly connected to the surface of the threaded connector. Compared with the comparative case, after the device completes the discharge of the material inside the packaging barrel body, the device is dismantled, so that the device can be recycled and only one set is needed, which effectively reduces the production cost of the packaging barrel;

[0013] 2. When installing the discharge pipe, align the two directional arrows with the two limit slots on the discharge pipe. The directional arrows facilitate the installation of the discharge pipe and the alignment of the limit slots and the limit strips. Then install the discharge pipe. When the discharge pipe moves downward, it will slide on the surface of the limit strip through the limit slots. At this time, the discharge pipe will be located between the two limit plates, so that the discharge pipe can be limited to prevent the discharge pipe from shaking in the packaging barrel.
