Description
Technical Field
The utility model relates to the technical field of compressors, in particular to a muffler suction end connecting structure of a compressor.
Background
At present, noise and vibration requirements of refrigeration compressors are increasingly high in the market. Most of the hermetically sealed refrigeration compressors can improve the purity of the sucked refrigerant by installing a corrugated pipe between a muffler and a suction pipe, and reduce suction pulsation noise. However, due to the periodic reciprocation of the piston, the suction pressure of the compressor pulsates, suction vibration is generated, and the corrugated pipe is easy to fall off. Therefore, the reliability of the connection structure between the muffler and the bellows of the compressor directly affects the operation stability of the compressor. In the prior art, chinese patent document with publication number CN 201836020U discloses a self-adaptive air intake structure applied to a totally-enclosed refrigeration compressor, a spring and a self-adaptive air suction port are sleeved on an air suction pipe of a silencer, a certain tight adhesion pressure is ensured between the air suction port of the air suction silencer and the inner wall of a shell, and connection of a corrugated pipe and the air suction pipe of the silencer is ensured through a clamp spring and a limiting step, but the structure is tedious and time-consuming in the actual production assembly process, so that the installation efficiency is lower, the number of accessories is increased, and the manufacturing cost is increased.
Disclosure of Invention
The utility model solves the technical problem of providing a connecting structure of the suction end of a compressor silencer, which is convenient for installing a corrugated pipe under the condition of ensuring the connection stability.
The technical scheme adopted for solving the technical problems is as follows: the muffler air suction end connecting structure of the compressor comprises a corrugated pipe and a muffler, wherein an air suction pipe opening is formed in the air suction end of the muffler, an air outlet pipe opening of the corrugated pipe is sleeved on the air suction pipe opening, and the corrugated pipe is matched with the air suction pipe opening in a clamping way through an annular bulge and an annular groove.
Further is: the corrugated pipe is characterized in that an annular groove is formed in the inner wall of the air outlet pipe opening of the corrugated pipe along the circumference of the inner wall of the air outlet pipe opening, an annular protrusion is arranged on the periphery of the air suction pipe opening, and the annular groove is connected with the annular protrusion in a clamping mode.
Further is: the air outlet pipe orifice is in interference fit with the air suction pipe orifice.
Further is: the muffler is characterized in that a positioning bulge is arranged at one end, close to the muffler, of the periphery of the air suction pipe orifice, a positioning notch is arranged at the end part of the air outlet pipe orifice of the corrugated pipe, and the positioning bulge is in clamping fit with the positioning notch.
Further is: the outlet pipe orifice of the corrugated pipe is made of elastic materials.
The beneficial effects of the utility model are as follows: the muffler is provided with the suction pipe orifice at the suction end, and then the suction pipe orifice is sleeved and installed with the suction pipe orifice through the air outlet pipe orifice of the corrugated pipe, so that quick assembly can be realized, and the corrugated pipe and the suction pipe orifice are directly realized in a limiting and fixing way through the clamping fit between the annular bulge and the annular groove, so that the connection stability is ensured, and no external fixing piece is required. The utility model has simple structure, convenient installation and improved installation efficiency.
Drawings
FIG. 1 is a schematic diagram of a first embodiment of the present utility model;
FIG. 2 is a schematic diagram of a second embodiment of the present utility model;
FIG. 3 is a schematic cross-sectional view of a muffler suction end connection structure;
marked in the figure as: muffler 1, suction pipe orifice 11, bellows 2, and outlet pipe orifice 21.
Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
Referring to fig. 1 to 3, the muffler suction end connection structure of the compressor of the present utility model includes a bellows 2 and a muffler 1, a suction pipe orifice 11 is disposed at the suction end of the muffler 1, an outlet pipe orifice 21 of the bellows 2 is sleeved on the suction pipe orifice 11, the bellows 2 and the suction pipe orifice 11 are engaged with each other by an annular protrusion and an annular groove, and the outlet pipe orifice 21 is in interference fit with the suction pipe orifice 11. Because the air outlet pipe orifice 21 is sleeved on the air suction pipe orifice 11, the air outlet pipe orifice 21 of the corrugated pipe 2 is made of elastic materials such as rubber, plastic and the like, so that the sleeve is conveniently realized; the air outlet pipe orifice 21 is in interference fit with the air suction pipe orifice 11, so that the air tightness and the connection stability of the installation are ensured.
Preferably, the inner wall of the air outlet pipe orifice 21 of the corrugated pipe 2 is provided with an annular groove along the circumference thereof, the periphery of the air suction pipe orifice 11 is provided with an annular bulge, and the annular groove is connected with the annular bulge in a clamping way, so that the corrugated pipe 2 at the connecting end is prevented from easily struggling off due to the internal vibration of the compressor.
In order to further ensure the installation stability, a positioning protrusion is arranged at one end, close to the silencer 1, of the periphery of the air suction pipe orifice 11, a positioning notch is arranged at the end part of the air outlet pipe orifice 21 of the corrugated pipe 2, and the positioning protrusion is in clamping fit with the positioning notch. In this way, the bellows 2 will not rotate on the outlet pipe orifice 21 due to vibration or external interference, so that the connection end will be loose, thereby affecting the air tightness and ensuring the refrigerant conveying efficiency.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
