Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1: the embodiment discloses a Y type filter screen locking device, including screw loop bar 1, interior pin 2 and reinforcement cover 6, but interior pin 2 sliding connection is in screw loop bar 1's inside, be equipped with between screw loop bar 1, the interior pin 2 and be used for driving the spring 3 that interior pin 2 popped out, screw loop bar 1's surface passes through threaded connection in movable nut 5, the thread length and the position of screw loop bar 1 surface set up as required, for example, at the tip of screw loop bar 1, owing to be used for cup jointing reinforcement cover 6, consequently, be not provided with the screw thread.

One end of the inner pin 2 is provided with a hand operation device, for example, a pull ring 7 can be adopted, and the pull ring 7 can be connected to the end part of the inner pin 2 in a folding way; the other end is connected with a reinforcing sleeve 6 through threads, and the reinforcing sleeve 6 is sleeved on the outer surface of the threaded sleeve rod 1 in a sliding manner.

In practical use, the reliability of the threaded connection between the end of the inner pin 2 and the reinforcing sleeve 6 needs to be ensured, and the looseness of the end of the inner pin 2 and the reinforcing sleeve 6 during use is avoided.

Specifically, the spring 3 is mounted in the following manner: threaded sleeve pole 1 still is equipped with and adds thick section 11, and interior pin 2 is equipped with to be connected in the annular arch 21 of adding thick section 11, and spring 3 cup joints in interior pin 2, and 3 one end of spring are connected in annular arch 21, and the other end is connected in the tip of adding thick section 11.

When the inner pin 2 and the reinforcing sleeve 6 are inserted into the connecting groove 81 through the spring 3, in order to further prevent the two from being separated from the connecting groove 81, the present embodiment is further provided with a locking device, and the specific structure thereof is as follows: the annular protrusion 21 is provided with an external thread 111, and the inner wall of the thickened section 11 is provided with an internal thread, and when the inner pin 2 is in a locked state, the thickened section 11 is connected to the external thread 111 through a thread. In order to improve the locking efficiency, the external thread 111 and the internal thread are preferably multi-start threads. Locking is achieved by rotating the annular projection 21 through a small angle.

In order to facilitate operation (the threaded sleeve rod 1 is prevented from rotating by tools such as a wrench and the like and is used during installation), a fixed nut 4 is further arranged on the outer side of the threaded sleeve rod 1, and the fixed nut 4 is fixedly connected to the threaded sleeve rod 1; furthermore, the fixed nut 4 can increase the contact area between the filter screen 9 and the present embodiment.

The hand-operated means of this embodiment is a pull ring 7, which pull ring 7 is foldably connected (rotatably connected to a through hole in the end of the inner pin 2) to the end of the inner pin 2.

During the use, pass the reservation through-hole on the filter screen 9 with screw loop bar 1, then the installation, and rotatory movable nut 5, through movable nut 5, decide nut 4 and realize the extrusion to filter screen 9, will consolidate cover 6 and rotate the tip to interior pin 2 after that, consolidate cover 6 like this and just can follow interior pin 2 and together follow the flexible slip of screw loop bar 1. Put into the inside to the filter with filter screen 9 at last, pulling pull ring 7, make interior pin 2, the 6 shrink of reinforcement cover then align the spread groove 81 of reserving on the 8 inner walls of filter can be under spring 3's elasticity, pin 2, reinforcement cover 6 enters into the inside to spread groove 81 jointly, realize filter screen 9 and filter 8's quick connection, after filter screen 9 is installed, through pin 2 in pull ring 7 rotation, can realize the locking through the annular is protruding 21 and add the screw-thread fit between the thick section 11, avoid pin 2, reinforcement cover 6 retracts.

For the screw connection among the prior art, this embodiment can realize high-speed joint, has avoided the trouble of screw thread to the hole. This embodiment is through reinforcing cover 6 and interior pin 2 cooperate with spread groove 81 jointly, and interior pin 2 is because the volume is limited, very thick that can not do, but reinforcing cover 6 cup joints the surface at screw thread loop bar 1, because the external diameter can be done than great, is favorable to promoting the intensity of this embodiment, avoids interior pin 2 to be bent. When the locking is completed, further locking between the inner pin 2 and the threaded shank 1 can be achieved by rotating the inner pin 2, avoiding the retraction of the inner pin 2.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
