A frame assembly for a frame pool and a frame pool including a frame assembly are provided. The frame assembly includes a horizontal support, a vertical support, a T-joint, and a coupling assembly releasably connecting a corresponding one of the horizontal support or the vertical support to the T-joint. The coupling assembly includes a collar having a tubular body. In some embodiments, a guide extends outwardly from the tubular body, and a limiting member moves through the guide between a locked position and an unlocked position to selectively retain the corresponding one of the horizontal support or the vertical support to the T-joint. In some embodiments, the limiting member is integrally formed with the tubular body and movable between the unlocked and locked positions to selectively retain the corresponding one of the horizontal support or the vertical support to the T-joint.

A safety ladder for a pool includes a movable ladder portion that can be moved between an accessible position and an inaccessible position. The movable ladder portion is disposed substantially outside of the pool and provides a series of steps that can be climbed vertically for entry into the pool when it is located in the accessible position. In the inaccessible position, the movable ladder portion is moved such that the steps can no longer be climbed and access to the pool is prevented. Such safety ladder assemblies are provided primarily to prevent children and other at risk individuals from entering an unattended pool. A dampening member is provided such that the force necessary to move the movable ladder portion is regulated to prevent a dangerous accumulation of moment and limit a risk of injury through harmful contact therewith.

A film forming treatment agent for a composite chemical conversion film for magnesium alloy, and a film forming process method, and a composite chemical conversion film are provided. Components of the film forming treatment agent for a composite chemical conversion film for magnesium alloy comprise a water solution and a suspension of reduced graphene oxide flakes to the water solution. The water solution comprises strontium ions at 0.1 mol/L to 2.5 mol/L and phosphate ions at 0.06 mol/L to 1.5 mol/L, and pH of the water solution is 1.5 to 4.5. Concentration of the reduced graphene oxide varies between 0.1 mg/L and 5 mg/L. The film forming process method for a composite chemical conversion film for magnesium alloy comprises the following steps of: 1) pretreatment on surface of magnesium alloy matrix; 2) immersion of magnesium alloy matrix in the film forming treatment agent; and 3) removal of magnesium alloy pieces for drying in air. The composite chemical conversion film for magnesium alloy is formed by immersing magnesium alloy matrix in the film forming treatment agent. The composite chemical conversion film for magnesium alloy has excellent corrosion-resistance performance in 3.5 wt % NaCl solution.

A filtering device includes a water pump, a filter cartridge, and a communicating tube for coupling the water pump with the filter cartridge. The filtering device further includes a flow switch attached to the communicating tube and configured to change switching states in response to a water flow rate in the communicating tube being lower than a predetermined value. The filtering device further includes a reminding device operably connected to the water flow switch. The reminding device generates a reminder signal when the state of the water flow indicates that the flow rate of the water in the communicating tube is lower than the predetermined value. The control system includes a control panel for the filtering pump, a central control system, and a filtration detecting system. The control panel is connected to the central control system and the central control system is connected to the filtration detecting system.

An above ground pool assembly comprises a bracket and a pool body. The bracket includes a plurality of horizontal and vertical support members. The horizontal support members couple to one another forming an upper frame. The plurality of vertical support members couple to the upper frame. The pool body has a side wall, wherein a top of the side wall is provided with a plurality of sleeves. The sleeves attach to the plurality of horizontal support members. Each horizontal support member has an outer surface with an uneven texture. The uneven texture reduces the contact areas between the pool body and the horizontal support members and avoids adhesion between the pool body and the horizontal support members, so that the pool body and the bracket can be separated easily, thereby reducing the possibility of damaging the pool body. Moreover, the wear resistance and slip resistance of the bracket are improved.
