Wherein the first mounting groove and the second mounting groove are annularly arranged along the inner wall of the buffer cavity,
and the longitudinal sections of the first mounting groove and the second mounting groove are both T-shaped structures.
The buffer piece comprises a first connecting portion connected with the first mounting groove, a second connecting portion connected with the second mounting groove and a buffer portion connecting the first connecting portion and the second connecting portion into a whole.
The first connecting part, the second connecting part and the buffer part form a conical cylinder; and is
The first connecting part is a small-neck end of the conical cylinder, and the second connecting part is a large-diameter end of the conical cylinder.
The first connecting portion and the second connecting portion are in interference connection with the corresponding mounting grooves respectively, and form detachable connection with the inner wall of the buffering portion through the positioning screws.
The conical cylinder composed of the first connecting part, the second connecting part and the buffering part is coaxial with the buffering cavity.
The first connecting portion, the second connecting portion and the buffering portion are all formed by processing rubber plates.
The beneficial effects of the utility model are that, the utility model discloses a liquid to getting into the cushion chamber has the effect of flexible buffering to elasticity that has through bolster itself prevents the impact of liquid to the pump body wall, thereby reaches the effect of making an uproar and protecting the pump body wall of falling, is particularly useful for the thin jade-wall pump body.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a longitudinal sectional view of the buffer portion of fig. 1.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Examples
As shown in fig. 1 and 2, the present embodiment 1 provides a pump body including: the pump comprises a pump body 1, wherein a pressurizing cavity 11 is arranged on the pump body 1, a water outlet hole 12 communicated with the pressurizing cavity 11 is also arranged on the pump body 1, a buffering part 2 is also arranged on the pump body 1, a buffering cavity 21 is arranged on the buffering part 2, and the buffering cavity 21 is communicated with the water outlet hole 12;
the inner wall of the buffer cavity 21 is sequentially arranged with a first mounting groove 211 and a second mounting groove 212, a buffer member 3 is arranged between the first mounting groove 211 and the second mounting groove 212, the size of the cavity of the buffer cavity 21 is suitable for being changed, and then the liquid entering the buffer cavity 21 is decelerated and buffered. Specifically, liquid enters into pressure boost chamber 11 from cushion chamber 21 in, and the water that gets into cushion chamber 21 makes liquid form the pressure boost because of the reason of water pipe, and then causes and gets into cushion chamber 21 water pressure increase, and then has increased the impact to cushion chamber 21 chamber wall, uses for a long time, causes the damage or pierces through to cushion chamber 21's chamber wall. The buffer cavity 3 is used for protecting the cavity wall of the buffer cavity 21, and water flow entering the buffer cavity 21 directly impacts the buffer component 3, so that the cavity wall of the buffer cavity 21 is protected from impact.
In this embodiment, the first mounting groove 211 and the second mounting groove 212 are both annularly disposed along the inner wall of the buffer cavity 21, and the longitudinal sections of the first mounting groove 211 and the second mounting groove 212 are both T-shaped structures. The connection tightness of the buffer member 3 and the mounting groove is increased.
As an alternative to the buffer.
Referring to fig. 2, the buffer member 3 includes a first connection portion 31 connected to the first mounting groove 211, a second connection portion 32 connected to the second mounting groove 212, and a buffer portion 33 integrally connecting the first connection portion 31 and the second connection portion 32.
In this embodiment, the first connecting portion 31, the second connecting portion 32 and the buffering portion 33 form a conical cylinder; and the first connection portion 31 is a small neck end of the tapered cylinder and the second connection portion 32 is a large diameter end of the tapered cylinder. Specifically, rivers get into bolster 31 after, through the effect of a toper section of thick bamboo, reduce rivers back grow again, and the pressure of rivers reduces gradually, has further alleviated the impact to the cushion chamber, avoids causing the wearing and tearing of cushion chamber or pierces through, and rivers all move ahead along the inner wall of buffering portion 33 simultaneously, can not directly strike the chamber wall of cushion chamber 21.
In this embodiment, first connecting portion 31 and second even connecting portion 32 are interference connection with the mounting groove that corresponds separately to form to can dismantle with the inner wall of buffer portion 2 through set screw and be connected, wear and tear back when bolster 3 uses for a long time, conveniently dismantle and change, simultaneously in order to improve first connecting portion 31 and second connecting portion 32 and buffer portion 2's reliability of being connected, with first connecting portion 31 and second connecting portion 32 embedding and form the rethread bolted connection after the location in the mounting groove that corresponds separately, also easy to assemble.
In this embodiment, the conical cylinder formed by the first connecting portion 31, the second connecting portion 32 and the buffering portion 33 is coaxial with the buffering cavity 21, so that the water entering the pressurizing cavity 11 is prevented from changing direction of the flow channel, and the water flow resistance is reduced.
In this embodiment, the first connecting portion 31, the second connecting portion 32, and the buffer portion 33 are all formed by processing a rubber plate. The rubber sheet has certain elasticity, makes things convenient for first connecting portion 31, second connecting portion 32 to fill in respective mounting groove to rivers take place to warp the buffering to its impact, reduce the influence collision.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
