Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a double screw pump screw rod with new profile of tooth molded lines, including the owner change screw rod 1, from changing screw rod 2 and the pump body 8, the owner changes screw rod 1 and changes two of equal fixedly connected with on the lateral wall of screw rod 2 and keep off and detain 6, the owner changes screw rod 1 and all overlaps from changing screw rod 2 and be equipped with to support tight cover 5, the owner changes screw rod 1 and changes equal threaded connection with fixation nut 4 on screw rod 2 from changing, the owner changes screw rod 1 and changes screw rod 2 from the owner and all rotate and connect on the pump body 8, pump body 8 is prior art, with the utility model discloses the innovation point is irrelevant, here is no longer repeated, and the owner changes screw rod 1 and all has cup jointed scroll 3, two 3 clearance fit of scroll from changing screw rod 2.

The cover is equipped with same stop collar frame 7 on the outer wall of two scroll sleeves 3, has seted up spacing opening 18 in stop collar frame 7 and has accomodate groove 12, the shape size of two scroll sleeves 3 and the phase-match of spacing opening 18, and scroll sleeve 3 and the inner wall laminating of stop collar frame 7.

Two containing grooves 12 are symmetrically distributed about a limiting through hole 18, a resisting plate 15 is arranged in each containing groove 12, one end, close to the spiral sleeve 3, of the resisting plate 15 is glued with a resisting rubber pad 16, and one end, far away from the resisting rubber pad 16, of the resisting plate 15 is provided with a resisting spring 14 and a resisting rod 13.

The tightening rod 13 is provided with a clamping block 20, one end of the tightening rod 13, which is far away from the tightening plate 15, is fixedly connected with a limiting block 10, the outer wall of the limiting sleeve frame 7 is fixedly connected with a lifting ring 9, the tightening rubber pad 16 is in contact connection with the spiral sleeve 3, and one end of the tightening rubber pad 16, which is close to the spiral sleeve 3, is provided with a plurality of anti-skidding slotted holes 17.

The friction force between the tight rubber mat 16 and the spiral sleeve 3 is larger due to the anti-skid slotted holes 17, so that after the tight plate 15 tightly supports the spiral sleeve 3, when the limit sleeve frame 7 is moved, the two spiral sleeves 3 can be fixed and limited and can move along with the limit sleeve frame 7, and the initial state can be kept between the two spiral sleeves 3 and the two spiral sleeves can be detached conveniently.

The abutting springs 14 and the abutting rods 13 are fixedly connected with the abutting plate 15, the abutting springs 14 are uniformly distributed on the abutting plate 15, the other ends of the abutting springs 14 are fixedly connected with the limiting sleeve frame 7, the limiting sleeve frame 7 is provided with a sliding hole 11, the abutting rods 13 penetrate through the sliding hole 11 and are connected onto the limiting sleeve frame 7 in a sliding mode, clamping holes 19 are formed in the side wall of the front end of the limiting sleeve frame 7 and the two abutting rods 13, and clamping blocks 20 are clamped in the clamping holes 19.

The working principle is as follows:

when the main rotating screw rod 1 or the secondary rotating screw rod 2 breaks down and needs maintenance, as shown in fig. 1, firstly, the position limiting sleeve frame 7 is sleeved on the two spiral sleeves 3, then the clamping block 20 is pulled out, the abutting plate 15 extends out of the accommodating groove 12 and clamps and limits the two spiral sleeves 3 under the elastic action of the abutting spring 14, the abutting rubber pad 16 enables the gripping force of the abutting plate 15 on the two spiral sleeves 3 to be stronger, then the clamping block 20 is clamped in the clamping hole 19, then the fixing nut 4 is screwed down, then the abutting sleeve 5 is dismounted, then the lifting ring 9 is pulled, the position limiting sleeve frame 7 is moved to the right by the lifting ring 9, the two spiral sleeves 3 move to the right along with the position limiting sleeve frame 7 at the same time, and therefore the initial state between the two spiral sleeves 3 can be kept and dismounted.

During the installation, because the spacing fixed action of stop collar frame 7, directly establish two 3 covers of scroll cover main change screw 1 and from changeing on the screw 2, then will support tight cover 5 and fixation nut 4 and install, then extract fixture block 20, and stimulate stopper 10, support tight spring 14 shrink and make and support tight board 15 shrink to accomodate the groove 12 in, then move stop collar frame 7 to the right, thereby dismantle stop collar frame 7 and be convenient for reuse, thereby when having avoided installing scroll cover 3 again main change screw 1 and from changeing screw 2, need carry out the trouble of calibration to the clearance distance between two scroll covers 3, the convenience of using improves greatly.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
