Abstract
The utility model discloses a special sealing and locking structure for a pipeline self-cleaning filter, and relates to the technical field of filler sealing. This special sealed locking structure of pipeline self-cleaning filter, including the packing groove, be provided with the packing groove internal thread on the packing groove, including the hexagon nut, the hexagon nut is as locking device's lock nut, the surface of hexagon nut is provided with the lock nut external screw thread, the lock nut external screw thread sets up with the internal screw thread fit in packing groove to make the hexagon nut compress tightly the filler. This special sealed locking structure of pipeline self-cleaning filter adopts predetermined hexagon nut and filled groove cooperation to set up, rather than using traditional bolt fastening, facilitates the use spanner etc. and screws up, and hexagon nut is compact structure for the bolt simultaneously, and occupation space is little, does not influence other parts of installation and equipment, need adjust the compression degree during the use, only need screw up hexagon nut can, convenient follow-up change packs.
Description
Technical Field
The utility model relates to the technical field of filler sealing, in particular to a special sealing and locking structure for a pipeline self-cleaning filter.
Background
At present, various sealing modes such as O-shaped ring sealing, mechanical sealing, packing sealing and the like are selected for shaft sealing, wherein the packing sealing needs to be pressed by a gland, and the packing generates radial force by utilizing the plasticity of the packing and is tightly contacted with a shaft, so that the sealing effect is achieved.
Traditional gland needs to use the bolt fastening, provides the pretightning force to make whole structure relatively more complicated, occupation space, manufacturing cost is higher.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides a special sealing and locking structure for a pipeline self-cleaning filter, which solves the problems that the traditional gland needs to be fixed by bolts and provides pretightening force, so that the whole structure is relatively complex, the occupied space is large, and the production cost is high.
(II) technical scheme
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a special sealed locking structure of pipeline self-cleaning filter, includes the packing groove, be provided with the packing groove internal thread on the packing groove, including the hexagon nut, the hexagon nut is as locking device's lock nut, the surface of hexagon nut is provided with the lock nut external screw thread, the lock nut external screw thread sets up with packing groove internal screw thread fit to make the hexagon nut compress tightly the filler, when the axle has relative motion with the filler, because the plasticity of filler, make locking structure produce radial force, and with axle in close contact with.
(III) advantageous effects
The utility model provides a special sealing and locking structure for a pipeline self-cleaning filter. The method has the following beneficial effects: this special sealed locking structure of pipeline self-cleaning filter, adopt predetermined hexagon nut and the cooperation setting of packing groove, rather than using traditional bolt fastening, it screws up (in the actual installation, the lifting surface area when using the hexagon nut is far more than the lifting surface area when using the bolt) to facilitate the use spanner etc. compact structure for the bolt simultaneously, occupation space is little, do not influence other parts of installation and equipment, need adjust the compression degree during the use, only need screw up the hexagon nut can, make things convenient for follow-up change to pack.

FIG. 3 is a top view of the hexagonal nut of the present invention;
FIG. 4 is a cross-sectional view of the packing channel of the present invention;
fig. 5 is a top view of the packing channel of the present invention.
In the figure: 1. a hexagonal nut; 2. locking the external thread of the nut; 3. a locking hole; 4. a packing groove; 5. a filling groove internal thread; 6. and (4) other structures of the packing groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a special sealed locking structure of pipeline self-cleaning filter, including packing groove 4, be provided with packing groove internal thread 5 on the packing groove 4, including hexagon nut 1, hexagon nut 1 is as locking device's lock nut, hexagon nut 1's surface is provided with lock nut external screw thread 2, lock nut external screw thread 2 sets up with the 5 cooperations of packing groove internal thread, thereby make hexagon nut 1 compress tightly the filler, when the axle has relative motion with the filler, because the plasticity of filler, make locking structure produce radial force, and with axle in close contact with.
To sum up, this special sealed locking structure of pipeline self-cleaning filter adopts predetermined hexagon nut and the cooperation setting of groove of packing, rather than using traditional bolt fastening, facilitate the use spanner etc. to screw up (in the actual installation, the lifting surface area when using the hexagon nut is far more than the lifting surface area when using the bolt), while the hexagon nut is compact structure for the bolt, occupation space is little, do not influence other parts of installation and equipment, need adjust the compression degree during the use, only need screw up the hexagon nut can, convenient follow-up change packs.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
Claims (1)
