TECHNICAL FIELD
[0001] The utility model relates to a daily tool of hardware lockset class, especially relates to a padlock among lockset classes, it is a kind of padlock rain cover (hereinafter referred to as "rain cover") that can be used as packaging box in the process of sale circulation both can protect padlock from rain erosion in outdoor protection. BACKGROUND
[0002] Padlock used in outdoor because often rain erosion and rust, serious time not only lock beam sluggish lock body corrosion even block lock hole lead to padlock lose use value, forced by circumstances many users can only use plastic bag etc. Simplely cover, also cannot fundamentally solve the problem and have to be subjected to wind and rain in open air.
[0003] It is known that, almost all padlock packaging box loses the value of preservation after the process of sale circulation is completed, and most consumers based on consensus of energy conservation and environmental protection are entangled with how to deal with those useless and regrettable packaging box. INVENTION CONTENTS
[0004] The utility model discloses a rain cover that can be used as packaging box, the purpose is to realize that the packaging box that loses the value of preservation is used as rain cover continuously, it can protect environment and also can protect padlock used in outdoor from rain erosion.
[0005] The manufacturing scheme includes cylinder, head, padlock entrance, packaging box cover, rope hole and the like, and the upper head and lower head are fixedly connected to the upper and lower ends of the cylinder respectively, the cylinder is tubular, and the cross section of the cylinder can be oval, circular or rectangular, etc., the geometric shape and size of the head are matched with the end face of the cylinder, and the connection between the cylinder and the head is fixed connection that can prevent rainwater from leaking into the cylinder, for example, the method of adhesive, hot melting or tight fit connection, etc. The length of the cylinder is about three times the total height of the padlock, and when manufacturing, the entrance that the padlock can enter is cut by cutting off a part of the cylinder, the position of the padlock entrance is in the middle of the longitudinal direction of the cylinder, the cut-off part is about one third of the total length of the cylinder, and the transverse direction cuts off about one half of the cross-sectional area of the cylinder, then several rope holes for tying ropes are processed in the middle position of the cylinder, and the other end of the rope can be tied on the lock catch (nose for locking doors), so as to prevent the rain cover from falling and facilitate storage and use.
[0006] The operation steps of using the rain cover as rain cover are as follows: first, hang the padlock on the lock catch and lock it, second, turn the padlock upward to inverted state, third, put the inverted padlock into the rain cover from the padlock entrance, fourth, insert the rain cover downward until the padlock is inserted into the top end of the cylinder, and finally, support the rain cover and arrange it to complete the operation.
[0007] The padlock is changed after being inverted, because the padlock is turned to the top of the lock as the fulcrum, under the action of gravity, the padlock will be in an unstable state of tilting at any time, in order to prevent the padlock from tilting together with the rain cover, it is necessary to increase the length of the cylinder to move the gravity center downward to prevent tilting and maintain stability, which is one of the important factors that the length of the cylinder needs to be three times the height of the padlock.
[0008] The usual way people use padlocks is to hang the padlock on the lock, and the lock is above the padlock, which is the normal state. Practice has proved that this state of the lock above the padlock is very unfavorable to the rainproof effect. Inverting the padlock to the top of the lock is to avoid the interference of the lock to achieve a more ideal rainproof effect.
[0009] When used as a packaging box, only need to put the padlock into the rain cover, cover the packaging box cover, and then use the adhesive tape to paste the packaging box cover firmly. According to the usual practice in the industry, the outer surface of the adhesive tape is printed with beautiful and eye-catching promotional graphics and text, and the outer surface of the packaging box is fully pasted. In this way, the promotional effect is improved, and the packaging box cover can be pasted more firmly.
[0010] The feasibility of using adhesive tape to fix the packaging box cover is based on the following three points:
[0011] 1. The scene of using the packaging box is basically during the storage, transportation and display of the product on the merchant's counter. During this period, the firmness of the packaging box cover is not high.
[0012] 2. It is convenient for consumers to open the packaging box and take out the padlock.
[0013] 3. Although the environment is harsh and the operation is frequent when used as a rain cover, the packaging box cover does not need to be added during the use of the rain cover (i.e. the firmness of the packaging box cover is irrelevant). Because of the obstruction of the lock, the rain cover with the packaging box cover cannot be used. Similarly, the rain cover cannot be added with the packaging box cover.
[0014] The utility model is preferably made of ABS or PVC plastic materials. The cylinder can be processed and manufactured by selecting appropriate specifications and sizes of round pipes, flat pipes (elliptical cross section) or square pipes (rectangular cross section) and other pipe materials. Of course, other materials and methods can also be used for molding.
[0015] Advantages
[0016] The utility model realizes the purpose of continuing to use the packaging box that has lost its value as a rain cover, protecting the environment and the padlock used outdoors from rain erosion.
[0017] When many users use the rain cover, it is equivalent to hanging the packaging box with advertising printed on it outdoors, expanding the publicity strength and range of the lock brand, and the advertising effect is worth looking forward to. BRIEF DESCRIPTION OF DRAWINGS
