Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, the present invention provides a high strength vent frame, including a mounting ring 2 fixedly connected to the outside of a ventilation duct 1; the outside of the ventilation pipeline 1 is also in sliding sleeve connection with a pushing pipe 4, a preset distance a is arranged between the end part of the pushing pipe 4 and the inside of the mounting ring 2, the outside of the pushing pipe 4 is in sliding sleeve connection with a clamping ring 3, and the inside of the pushing pipe 4 is also provided with a filtering piece 42; the outer peripheral surface of the snap ring 3 is in threaded connection with the inner peripheral surface of the mounting ring 2, and the snap ring 3 is arranged at the opening of the mounting ring 2.

A plurality of fixture blocks 41 are uniformly arranged on the periphery of the pushing pipe 4; referring to fig. 2, the snap ring 3 is provided with a plurality of clamping grooves 31 and through grooves 32, and the through grooves 32 are through along the length direction of the snap ring 3; card slot 31 and through groove 32 set up at an interval each other, and the quantity of card slot 31 or through groove 32 all equals with the quantity of fixture block 41, and card slot 31 and through groove 32 all use with fixture block 41 cooperation. Through the combined action of the fixture block 41 and the clamping groove 31 or the through groove 32, the push pipe 4 and the clamping ring 3 have sliding sleeve connection relation and clamping connection relation.

In the normal use process of the pushing pipe 4, the clamping ring 3 is in threaded connection with the mounting ring 2, and the position of the clamping ring 3 is fixed; the pushing pipe 4 is sleeved in the clamping ring 3, the clamping blocks 41 are clamped in the clamping grooves 31, and the pushing pipe 4 is fixed; the air enters the ventilation duct 1 from the push pipe 4, and needs to pass through the filtering member 42, and the air is filtered and decontaminated by the filtering member 42.

When the push pipe 4 needs to be replaced or the filter element 42 needs to be cleaned, the push pipe 4 is pushed towards the direction A, and the push pipe 4 can be freely pushed or pulled out as the ventilation pipeline 1 is slidably sleeved inside the push pipe 4 and the clamping ring 3 is slidably sleeved outside the push pipe 4; when the clamping ring 3 is screwed out in the direction B, the fixture block 41 is completely separated from the clamping ring 3, and the fixture block 41 is no longer clamped in the clamping groove 31; then, by rotating the snap ring 3 so that the through groove 32 corresponds to the snap block 41, the entire push tube 4 can be pulled out of the snap ring 3, thereby facilitating replacement of the push tube 4 or cleaning of the filter element 42.

When needing to install impulse pipe 4, insert in snap ring 3 with impulse pipe 4, and cup joint the outside at air pipe 1, the in-process inserts, fixture block 41 on the impulse pipe 4 gets into from leading to groove 32, enter into the collar 2 completely when fixture block 41, and leave behind snap ring 3, rotatory snap ring 3 (this moment, to A direction precession), it is corresponding to make fixture block 41 and draw-in groove 31, again to B direction pulling impulse pipe 4, make fixture block 41 and draw-in groove 31 joint completely, then the rigidity of impulse pipe 4 and snap ring 3, the installation of impulse pipe 4 is accomplished.

Preferably, the outside of snap ring 3 still is equipped with rotating handle ring 33, and rotating handle ring 33 sets up in the outside of collar 2, and rotating handle ring 33 makes things convenient for the staff to rotate snap ring 3 promptly, can prescribe a limit to the precession position of snap ring 3 again.

Preferably, the ventilation duct 1 is further sleeved with an elastic element 11, the elastic element 11 is arranged inside the mounting ring 2, one end of the elastic element 11 abuts against the mounting ring 2, and the other end abuts against the end of the pushing pipe 4; when the pushing tube 4 is pushed in the direction a, the elastic member 11 is compressed, and when the latch 41 on the pushing tube 4 corresponds to the latch slot 31 or the through slot 32, the latch slot 31 or the through slot 32 can be quickly inserted into the latch slot 31 or the through slot 32 under the resetting action of the elastic member 11. Preferably, one end of the elastic element 11 close to the pushing tube 4 is fixedly connected with an elastic plate 12, the elastic plate 12 abuts against the end part of the pushing tube 4, and the abutting of the pushing tube 4 and the elastic element 11 is more stable through the action of the elastic plate 12.

In the present invention, there are four clamping blocks 41, and correspondingly, there are four clamping grooves 31 and four through grooves 32. Every 45 degrees of rotation of the snap ring 3 just changes the latch 41 from the position corresponding to the snap groove 31 to the position corresponding to the through groove 32.

In the present invention, two filter members 42 are provided to sufficiently filter the air introduced into the ventilation duct 1.

In summary, the installation frame of the filter element is formed by the installation ring, the pushing pipe and the clamping ring together through the structure, and the clamping block outside the pushing pipe can be movably clamped in the clamping ring so as to position the pushing pipe and the filter element; when the push pipe needs to be replaced or the filter piece is cleaned, the clamping ring is rotated, the clamping block corresponds to the through groove in the clamping ring, the push pipe can be pulled out, and the pushing pipe is connected with the ventilation pipeline in a clamping mode in a detachable mode. In conclusion, the beneficial effects of the utility model are as follows: installation frame simple structure connects through the joint formula, even the long-time use of filtration, filtration's installation is also very convenient with the dismantlement, and labour saving and time saving makes things convenient for filtration's washing or change, avoids damaging filtration, and the practicality is better.
