Description

Technical Field

[0001] The present application relates to the field of liquid containers, and in particular to a liquid material barrel cover. Background Art

[0002] Chemical production requires a wide range of chemical raw materials, many of which are liquid. During the reaction and processing of these liquid chemical raw materials, they need to be stored in a sealed manner using storage facilities, of which barrel containers are one of the most common.

[0003] In related art, a barrel-shaped container comprises a barrel body and a lid. The barrel body has a spout at the top, fixed with a threaded tube. The lid is located at the spout and is detachably connected to the barrel body via a threaded connection, controlling the opening and closing of the spout. Some containers have two spouts, each with a corresponding lid connected to a different-sized threaded tube. Liquids can be placed or opened based on specific operating requirements.

[0004] For barrel covers with smaller radial dimensions, it is difficult for an operator to apply torque to rotate it by hand, especially when the operator's hands are greasy, so the operator has to take an additional torque tool, which increases the inconvenience of the operation. Utility Model Content

[0005] In order to improve the above problems, the present application provides a liquid material barrel cover.

[0006] The liquid material barrel cover provided in this application adopts the following technical solution:

[0007] A liquid material barrel cover includes a main cover body and a sub-cover body. The barrel body is provided with two barrel mouth threaded tubes. The main cover body and the sub-cover body are respectively threadedly connected to a barrel mouth threaded tube. The main cover body is provided with a force-applying structure, and the sub-cover body is provided with a matching structure for matching with the force-applying structure. After the force-applying structure and the matching structure match each other, the main cover body transmits torque to the sub-cover body.

[0008] By adopting the above technical solution, if the auxiliary cover is smaller than the main cover and the smaller auxiliary cover needs to be opened, the main cover is removed, the force-applying structure and the matching structure cooperate with each other, and then the main cover is operated to apply torque to the auxiliary cover, thereby achieving the purpose of opening the auxiliary cover, and the operation is more convenient.

[0009] Preferably, the force-applying structure includes a structural groove and a force-applying ridge, the structural groove is coaxially opened on the side of the main cover body facing away from the barrel body, the force-applying ridge is fixedly connected to the groove wall of the structural groove, the length direction of the force-applying ridge is parallel to the axial direction of the structural groove, the matching structure includes a matching ridge, the matching ridge is connected to the outer side wall of the auxiliary cover body, the structural groove is for the auxiliary cover body to be inserted, and the force-applying ridge is located on one side of the matching ridge.

[0010] By adopting the above technical solution, after the auxiliary cover enters the structural groove, the main cover rotates, and the contact and abutment force generated by the matching edge and the force-applying edge serves as the torque for rotating the auxiliary cover, thereby realizing torque transmission between the two covers.

[0011] Preferably, there are multiple force-applying edges and multiple matching edges, the number of the force-applying edges is equal to the number of matching edges, the multiple force-applying edges are arranged in a circular array with the axis of the structural groove as the center, and the matching edges are arranged in a circular array around the axis of the auxiliary cover body, and the gap between adjacent force-applying edges is greater than the width of the matching edges.

[0012] By adopting the above technical solution, the operation of inserting the auxiliary cover into the structural groove is made more convenient and quick.

[0013] Preferably, a plurality of structural ridges are provided on the side wall of the main cover body, the length direction of the structural ridges is parallel to the axial direction of the main cover body, and a lead sealing gap is provided between the structural ridges and the main cover body.

[0014] By adopting the above technical solution, the user can set a lead seal on the main cover through the lead seal gap.

[0015] Preferably, the end of the matching edge away from the barrel body is provided with a matching fillet.

[0016] Preferably, the main cover and the auxiliary cover are integrally connected with an anti-theft ring in a breakpoint manner on one side facing the barrel body, and the anti-theft ring is sleeved and clamped on the barrel mouth threaded tube.

[0017] Preferably, a trapezoidal block is fixedly connected to the anti-theft ring, and a trapezoidal groove is provided on the main cover body and the auxiliary cover body. The trapezoidal block is located in the trapezoidal groove. When the main cover body or the auxiliary cover body is screwed out from the threaded tube, the inclined groove wall of the trapezoidal groove abuts the inclined side wall of the trapezoidal block, and the groove wall of the trapezoidal groove applies a thrust toward the barrel body to the trapezoidal block.

[0018] By adopting the above technical solution, when the main cover or the auxiliary cover is unscrewed from the barrel mouth threaded tube, the groove wall of the trapezoidal groove applies thrust to the trapezoidal block, and the anti-theft ring is easier to separate from the main cover or the auxiliary cover after being subjected to the force.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting up a main cover with a force-applying structure and a sub-cover with a matching structure, when the smaller sub-cover needs to be opened, the main cover is removed, the force-applying structure and the matching structure are engaged with each other, and then the main cover is operated to apply a torque to the sub-cover, thereby achieving the purpose of opening the sub-cover, which is relatively convenient to operate;

[0021] 2. Through the arrangement of the trapezoidal groove and the trapezoidal block, when the main cover or the auxiliary cover is unscrewed from the barrel mouth threaded tube, the groove wall of the trapezoidal groove exerts a thrust on the trapezoidal block, and the anti-theft ring is more easily separated from the main cover or the auxiliary cover after being subjected to the force.

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] The embodiment of the present application discloses a liquid material barrel cover, such as Figure 1 and 2 As shown, two barrel-mouth threaded tubes (not shown) are fixedly mounted on the top of the barrel body 1. The two barrel-mouth threaded tubes have different diameters. The barrel lid comprises a main lid body 2 and a secondary lid body 3. The main lid body 2 is threadedly connected to the larger barrel-mouth threaded tube, and the secondary lid body 3 is threadedly connected to the smaller barrel-mouth threaded tube, thereby sealing the corresponding barrel-mouth threaded tubes. The main lid body 2 is provided with a force-applying structure 21, and the secondary lid body 3 is provided with a mating structure 31 that cooperates with the force-applying structure 21. When the force-applying structure 21 and the mating structure 31 cooperate with each other, the main lid body 2 can transmit torque to the secondary lid body 3, thereby enabling the main lid body 2 to open the secondary lid body 3.

[0028] like Figure 1 and 2As shown, the force-applying structure 21 includes a structural groove 211 and a force-applying rib 212. The structural groove 211 is a circular groove coaxially defined on the side of the main cover 2 facing away from the barrel body 1. The force-applying rib 212 is integrally formed on the wall of the structural groove 211. The length of the force-applying rib 212 is parallel to the axial direction of the structural groove 211. The mating structure 31 includes a mating rib 311 integrally formed on the outer wall of the auxiliary cover 3. In this embodiment, the number of mating ribs 311 and the number of force-applying ribs 212 are both eight. Each force-applying rib 212 is arranged in a circular array centered on the axis of the structural groove 211. Each mating rib 311 is arranged in a circular array around the axis of the auxiliary cover 3. A mating fillet 312 is provided on the end of the mating rib 311 away from the barrel body 1. The gap between adjacent force-applying ribs 212 is five times the width of the mating rib 311 itself. During operation, the force-applying structure 21 and the mating structure 31 are more convenient and quick to coordinate. After the auxiliary cover body 3 enters the structural groove 211 , the main cover body 2 is rotated, and the matching edge 311 contacts the force-applying edge 212 , thereby realizing torque transmission between the two cover bodies.

[0029] like Figure 1 and 2 As shown, the main cover 2 has a plurality of structural ridges 22 disposed on its sidewalls. The length of the structural ridges 22 is parallel to the axial direction of the main cover 2. The arrangement of the structural ridges 22 relative to the main cover 2 is consistent with the arrangement of the mating ridges 311 relative to the auxiliary cover 3. A lead seal notch 23 is defined between the structural ridges 22 and the main cover 2, allowing the user to apply a lead seal to the main cover 2.

[0030] like Figure 1 、 2 As shown in Figure 3, the main cover 2 and the cover are both plastic parts. The main cover 2 and the sub-cover 3 are connected to the barrel body 1 in a breakpoint-type integrated manner with an anti-theft ring 5. The anti-theft ring 5 is sleeved on the barrel mouth threaded tube and vertically clamped with the barrel mouth threaded tube. A trapezoidal block 51 is fixedly connected to the anti-theft ring 5. A trapezoidal groove 4 is provided on both the main cover 2 and the sub-cover 3. When the anti-theft ring 5 and the main cover 2 or the sub-cover 3 are in a breakpoint-connected state, the trapezoidal block 51 is correspondingly located in the trapezoidal groove 4. In this embodiment, the number of trapezoidal blocks 51 and trapezoidal grooves 4 on a single cover is two. When the main cover 2 or the sub-cover 3 is unscrewed from the threaded tube, the inclined groove wall of the trapezoidal groove 4 abuts the inclined side wall of the trapezoidal block 51. The groove wall of the trapezoidal groove 4 applies a thrust to the trapezoidal block 51 toward the barrel body 1. After the force is applied, the anti-theft ring 5 is more easily separated from the main cover 2 or the sub-cover 3.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
