Description

Technical Field

[0001] The utility model relates to the technical field of anti-dropping water inlet connectors for washing machines, in particular to an anti-dropping water inlet connector for washing machines. Background Art

[0002] A washing machine is a household appliance that uses electrical energy to generate mechanical action to wash clothes. A washing machine is usually composed of a cabinet, a washing and dehydrating barrel (some washing machines have separate washing and dehydrating barrels), a transmission and control system, etc. Some washing machines are also equipped with heating devices. Washing machines are divided into two categories according to their rated washing capacity: household and collective use. China stipulates that washing machines with a washing capacity of less than 6 kilograms are household washing machines. The main function of a washing machine is to use water and detergent to remove stains and dirt from clothes through mechanical movement. It can not only thoroughly clean clothes and make them cleaner and more hygienic, but also perform multiple steps such as rinsing and dehydration to make the laundry process simpler and more convenient. Washing machines are divided into several types according to their functions, such as fully automatic washing machines, semi-automatic washing machines and pulsator washing machines. Fully automatic washing machines can complete all washing operations without human intervention. Fully automatic washing machines need to be installed through the water inlet pipe. The water inlet pipe is connected to the faucet to achieve the purpose of automatic water inlet. After the washing machine completes the washing work each time, tap water will accumulate in the water inlet pipe. If it is not cleaned in time, a large number of bacteria will grow inside the water inlet pipe, which will contaminate the clothes when washing next time. Therefore, the water inlet pipe needs to be provided with a quick-release joint connected to the faucet to achieve the purpose of quick disassembly and assembly, so as to facilitate the cleaning of the water inlet pipe. The inner wall of the existing anti-falling water inlet connector for washing machines has a plurality of balls. When the washing machine faucet is connected, the outer jacket of the interface is pulled down by hand, and after it is put on the faucet, the balls automatically pop out and are stuck in the groove of the special faucet for the washing machine to complete the connection. The traditional anti-falling water inlet connector for washing machines is connected to the card slot through the ball bearings, and the fixing effect of the friction card connection is low. When the water pressure is large, the friction fails, and the washing machine water inlet pipe connector will be washed open by the huge water pressure. For this reason, we propose an anti-falling water inlet connector for washing machines. Utility Model Content

A locking mechanism is also provided to prevent the connection from shifting, further improving the connection strength between the water inlet pipe of the washing machine and the faucet.

[0025] The working principle of the anti-falling water inlet connector for a washing machine provided by the utility model is as follows: when installing the anti-falling water inlet connector for a washing machine, first connect the connecting pipe 2 with the faucet, fit the upper end of the connecting pipe 2 with the lower end of the faucet, and then rotate the sleeve 3 to make the inner wall of the sleeve 3 and the outer surface of the faucet threadedly connected, and the sealing rubber pad at the upper end of the connecting pipe 2 makes the sealing effect better. At this time, the connecting pipe 2 is connected to the faucet, the lower end of the installation column 1 is connected to the water inlet pipe, and the upper end of the installation column 1 is fit with the lower end of the connecting pipe 2. At the same time, align the upper end of the connecting rod 42 with the notch of the connecting groove 43, and push the connecting slip ring 41 upward. The outer surface of 46 is slidably connected with the inner wall of the avoidance opening 47, so as the connecting slip ring 41 moves upward, the mounting ring 44 will also move upward, slowly moving the mounting column 1 upward, the tension spring 45 is expanded under force, the upper end of the connecting rod 42 enters the interior of the connecting groove 43, and then slowly rotates the connecting slip ring 41 to the left along the inner wall of the connecting groove 43. Since the upper end of the mounting column 1 and the middle part of the lower end of the connecting pipe 2 are both provided with sealing pads, the sealing pads are elastic, and as the connecting slip ring 41 rotates, the connecting pipe 2 and the mounting column 1 fit more closely, and the sealing pad also fits more closely, until the upper end of the connecting rod 42 reaches a suitable position, the connecting pipe 2 and the mounting column 1 are The sealing effect reaches the best. At this time, the locking groove 8 is vertically adjacent to the locking plug column 7, and the spring 6 is not expanded without force, driving the locking ring 5 to move up, and the locking plug column 7 moves up synchronously until the upper end of the locking plug column 7 is inserted into the locking groove 8, forming a limiting effect on the connecting slip ring 41. Since the inner walls of the sliding groove 10 and the locking ring 5 are both hexagonal inner walls, the locking ring 5 will not deviate, which can effectively prevent the connecting slip ring 41 from deviating, so that the connection effect between the water inlet pipe of the washing machine and the faucet is optimal. When the connection between the water inlet pipe of the washing machine and the faucet needs to be disconnected, it is only necessary to pull down the locking ring 5, and the spring 6 is forced to shrink until the locking plug column 7 completely leaves the locking groove 8. The connecting slip ring 41 is rotated to the right until the connecting rod 42 is aligned with the notch again, the connecting slip ring 41 is released, the tension spring 45 is contracted without force, and the mounting ring 44 moves down accordingly, pulling the connecting slip ring 41 back to its original position. At this time, the connecting pipe 2 is disconnected from the mounting column 1, and the water inlet pipe of the washing machine can be quickly disassembled and assembled. An anti-falling mechanism is provided to prevent the water inlet connector of the washing machine from falling off through hard contact, effectively avoiding the water inlet connector of the washing machine from being washed away due to friction failure caused by excessive water pressure. A locking mechanism is also provided to prevent the connection from being offset, further improving the connection strength between the water inlet pipe of the washing machine and the faucet.
