[0001] The utility model relates to the technical field of packing container, more specifically, it relates to a metal drum. BACKGROUND
[0002] Steel drum is a kind of metal drum, although the application of steel drum has only a history of more than one hundred years, but its development is very fast, and there are many varieties, which are widely used in industrial product packaging, transportation packaging and sales packaging. And it has also become a means for long-term preservation of the contents, which can be said that steel drum has brought great changes and progress to human work and life.
[0003] The existing steel drum top surface often needs to reserve a concave area, which plays a role in stacking steel drums up and down, so rainwater is easy to accumulate on the steel drum top surface, and the existing steel drum top surface often does not have a drainage structure, which needs to be manually drained or covered with waterproof material on the steel drum top surface to prevent water accumulation. If the cover on the opening of the steel drum is not tightened or the sealing effect is reduced, and there is too much water on the top surface of the steel drum, the water will overflow to the opening of the cover, and due to the temperature difference between day and night, negative pressure will be generated in the barrel, and the water will easily flow into the steel drum from the opening, thereby affecting the normal use of the steel drum.
[0004] Therefore, a new scheme is needed to solve this problem. UTILITY MODEL CONTENTS

[0016] The utility model will be described in detail below in combination with the drawings and examples.
[0017] A kind of metal barrel, such as Figure 1 And Figure 2As shown, including barrel 1, top cover 2 and bottom cover 3, top cover 2 is provided with an injection port 4, top cover 2 top surface is provided with a plurality of guide groove 6, guide groove 6 from the center of top cover 2 to the edge of top cover 2 extends, the groove depth of guide groove 6 from the center of top cover 2 to the edge of top cover 2 gradually deepens, barrel 1 is provided with a plurality of drain hole 7 on the outer wall, drain hole 7 through barrel 1 and the deepest end of guide groove 6 groove depth communication, injection port 4 is detachably connected with cover 5, when the empty barrel is placed outdoors, and there is water on top cover 2, the water flows to the edge of top cover 2 through guide groove 6, and the water is discharged from top cover 2 through drain hole 7 on barrel 1 which is communicated with guide groove 6, by reducing the water on top cover 2, even if the barrel 1 shrinks due to external temperature and other problems, because the water on top cover 2 is less, it is not easy to suck into, even if the rainwater is limited.
[0018] As shown in Figure 1 and Figure 2 , the metal barrel is mainly composed of barrel 1, top cover 2 and bottom cover 3, top cover 2 is provided with an injection port 4 for injecting liquid into the barrel, injection port 4 is provided with a detachable cover 5, such as screw cap or buckle cover, for sealing injection port 4 when not in use, to prevent liquid leakage, barrel 1, top cover 2 and bottom cover 3 are made of galvanized stainless steel material, and the thickness of barrel 1, top cover 2 and bottom cover 3 is between 1.5-3mm, 1.5-3mm is relatively thick in the metal barrel, which is usually used for industrial storage or large capacity requirement, and the thick wall thickness is convenient for the formation of subsequent guide groove 6 and drain hole 7, guide groove 6 is a straight line extending from the center of top cover 2 to the edge of top cover 2 from the perspective, the groove depth of guide groove 6 is not fixed, the shallowest groove depth of guide groove 6 is at the center of top cover 2, and the deepest groove depth of guide groove 6 is at the edge of top cover 2, that is, the groove depth of guide groove 6 gradually deepens from the center of top cover 2 to the edge of top cover 2, which is convenient for the water on the top surface of top cover 2 to flow from the center of top cover 2 to the edge of top cover 2, a plurality of guide grooves 6 are arranged in a circular array on the top surface of top cover 2, and the center of the circular array is the center of top cover 2, if the shape of top cover 2 is not cylindrical, the center of the circular array of guide groove 6 is the center point of the top surface of top cover 2, the circular array can uniformly disperse the water to the edge of top cover 2, preferably, the minimum number of guide grooves 6 is 6, compared with 2 and 4, 6 and above can more evenly and quickly disperse the water to the edge of top cover 2, the specific number can be adjusted according to the capacity and design requirement of the barrel, the maximum groove depth of guide groove 6 is 0.5-1mm, which can effectively guide the liquid and will not affect the overall structural strength of top cover 2 due to the excessive groove depth.
[0019] As shown in Figure 1 and Figure 2As shown, the outer peripheral wall of the barrel body 1 is uniformly distributed with several drain holes 7, which penetrate the barrel wall and are directly connected with the deepest end of the flow guide groove 6. The drain hole 7 is designed as a straight hole, and the opening direction thereof is towards the bottom cover 3. Such design is beneficial to the natural flow of liquid under the action of gravity, reduces the resistance during discharge, and at the same time, the straight hole structure is easy to process, which reduces the production cost. The flow guide groove 6 and the drain hole 7 both adopt a circumferential array layout, i.e. they are uniformly distributed around the center of the top cover 2 and the outer periphery of the barrel body 1, respectively. In order to ensure the balance and efficiency of liquid flow, the number of the flow guide groove 6 is consistent with the number of the drain hole 7, for example, both of them can be set to 8 or 12, and the specific number can be adjusted according to the capacity of the barrel and the design requirement. In order to ensure that the liquid can smoothly flow from the flow guide groove 6 into the drain hole 7, the vertical sectional area of the drain hole 7 is designed to be larger than the vertical sectional area of the flow guide groove 6. This design ensures that even when the liquid flow is large, it can effectively avoid blockage and ensure a smooth discharge process.
[0020] In order to further enhance the strength and stability of the top cover 2, especially the reinforcing ribs 8 consistent with the number of the flow guide groove 6 are additionally arranged below the flow guide groove 6. These reinforcing ribs 8 not only provide additional support, but also help to disperse the pressure received by the top cover 2, thereby prolonging the service life of the metal barrel.
[0021] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the scope of the present application should be considered as falling within the protection scope of the present application. It should be noted that for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principles of the present application should also be considered as falling within the protection scope of the present application.
