The utility model provides a its technical problem take following technical scheme to realize:
the utility model provides a slip locking formula filter, includes filter bowl, filter head, sintering filter screen and filter membrane the installing port department spiral-lock of filter head has the filter bowl, and the filter membrane has been pressed from both sides to the pressure between filter bowl and filter head, installs sintering filter screen, its characterized in that on the boss of the lower part filter head of filter membrane: the filter comprises a filter head mounting opening, a filter cup, a cup mouth cover and a filter cup, wherein the filter head mounting opening is arranged on the outer portion of the filter cup, two ends of the filter cup mouth are symmetrically provided with sliding locking openings, each sliding locking opening is composed of a vertical assembling portion, an inclined transition portion and a horizontal positioning portion which are communicated with each other, the lower end of the inclined transition portion is provided with a vertical assembling portion with an opening, the horizontal positioning portion is arranged above the inclined transition portion, positioning columns matched with the sliding locking openings are symmetrically arranged at the outer edges of two sides of the filter head mounting opening, during assembly, the positioning columns are firstly located at the vertical assembling portion, and are locked and positioned by sliding the inclined transition portion to the horizontal positioning portion along with screwing of the filter cup, so that the assembly of the filter cup and the filter head is.
And one end of the positioning column is inserted into the filter head, the other end of the positioning column extends out of the outer edge of the mounting port of the filter head, and the length of the positioning column inserted into the filter head is greater than the length of the positioning column extending out of the filter head.
The utility model has the advantages that:
1. this slip locking formula filter, through the structural design who connects filter bowl and filter head with traditional dependence clip for the structure of twisting the formula soon, the principle that utilizes spiral locking reaches filter bowl and filter head and compresses tightly the filter membrane, and guarantee the purpose of sealed effect, be about to after the filter bowl spiral-lock is on the filter head (the reference column is located vertical assembly portion this moment), twist the two soon, make the reference column slide to horizontal location portion on, the assembly of filter bowl and filter head has been accomplished promptly, realized the purpose that compresses tightly the filter membrane. The control of the clamping point is omitted, the operation is convenient, the experiment efficiency is greatly improved, and meanwhile, the reliability of the experiment and the accuracy of the experiment data are improved due to the fact that no liquid leaks.
2. This slide locking formula filter, through the length design that injects the reference column into the filter head for being greater than the length that stretches out the filter head, guaranteed the firmness of reference column to guarantee to revolve the reliability of twisting, and then guarantee the reliable connection of filter head and filter bowl.
3. The utility model has the advantages of scientific and reasonable design, have convenient equipment, improve the packaging efficiency, reduce experimenter intensity of labour, improve experimental efficiency and experimental data accuracy, be a slide locking formula filter that has higher novelty.
