Abstract
The utility model discloses a connection structure of an air inlet pipe of a rotary type compressor. The connection structure comprises an air inlet pipe connection end, wherein at least one boss is arranged at the outer circle of the air inlet pipe connection end in the peripheral direction at an interval; the top end of each boss is higher than the peripheral surface of the outer circle of the air inlet pipe connection end. According to the connection structure, the assembling efficiency of the air inlet pipe can be effectively improved; the welding resistance between the air inlet pipe and a copper pipe of an air inlet seat ring of the compressor is reduced and the welding discharging in the welding process is avoided; the reliable connection between the air inlet pipe and the copper pipe of the air inlet seat ring is ensured and the assembling cost of the air inlet pipe is reduced.
Description
Technical field
The utility model relates to a kind of linkage structure of rotary compressor suction tude.
Background technique
Conventionally in rotary compressor assembling work process, the major part cylindrical of suction tude connecting end stretches into the copper pipe inner circle of compressor gas inlet seat ring and becomes Spielpassung, assembling normal operation need get ready the copper pipe inner circle of compressor gas inlet seat ring, so that the suction tude that connects cylinder be connected the connection that realizes beeline between the copper pipe of gas inlet seat ring of housing, prevent in welding process process because of welding striking current loop not smooth, and the welding occurring between compressor pump electric discharge.This assembling work process has reduced operating efficiency, increase the clamping apparatus of artificial, cost of supplementary product and assembling, and the clamping apparatus of getting ready of assembly process seat ring copper pipe inner circle easily weares and teares, cause suction tude to be connected incomplete phenomena with the copper pipe of gas inlet seat ring, thereby affect the assembly quality of suction tude.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of linkage structure of rotary compressor suction tude, utilize this linkage structure can effectively improve the efficiency of assembling of suction tude, reduce the welding resistance between suction tude and gas inlet seat ring copper pipe, avoid the welding electric discharge of welding process, guarantee that suction tude is connected with the reliable of gas inlet seat ring copper pipe, reduce the assembly cost of suction tude.
For solving the problems of the technologies described above, the linkage structure of the utility model rotary compressor suction tude comprises suction tude connecting end, described suction tude connecting end cylindrical is along the circumferential direction interval with at least one boss, and described boss top is higher than the circumferential surface of described suction tude connecting end cylindrical.
Further, above-mentioned suction tude connecting end cylindrical is along the circumferential direction interval with four boss.
Further, above-mentioned four boss at described suction tude connecting end cylindrical uniformly at intervals.
Because the linkage structure of the utility model rotary compressor suction tude has adopted technique scheme, be that this linkage structure comprises suction tude connecting end, described suction tude connecting end cylindrical is along the circumferential direction interval with at least one boss, and described boss top is higher than the circumferential surface of described suction tude connecting end cylindrical.This linkage structure can effectively improve the efficiency of assembling of suction tude, reduces the resistance between suction tude and compressor gas inlet seat ring copper pipe, avoids the welding electric discharge of welding process, guarantees that suction tude is connected with the reliable of gas inlet seat ring copper pipe, reduces the assembly cost of suction tude.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the linkage structure schematic diagram of the utility model rotary compressor suction tude;
Fig. 2 utilizes the suction tude of this linkage structure and the connection diagram of gas inlet seat ring copper pipe.
Embodiment
As shown in Figure 1, the linkage structure of the utility model rotary compressor suction tude comprises suction tude connecting end 1, described suction tude connecting end 1 cylindrical 11 is along the circumferential direction interval with at least one boss 2, and described boss 2 tops are higher than the circumferential surface of described suction tude connecting end 1 cylindrical 11.
Further, preferred above-mentioned suction tude connecting end 1 cylindrical 11 is along the circumferential direction interval with four boss 2.
Further, above-mentioned four boss 2 at described suction tude connecting end 1 cylindrical 11 uniformly at intervals.
As shown in Figure 2, when the suction tude assembling work of rotary compressor 3, the suction tude connecting end 1 of this linkage structure can directly be pressed in the copper pipe 32 of compressor 3 gas inlet seat rings 31, suction tude connecting end 1 cylindrical copper pipe 32 inner circle close contacts of spaced boss 2 and gas inlet seat ring 31 along the circumferential direction now, realize suction tude and be connected with gas inlet seat ring 31 copper pipe 32 both reliable, the boss 2 of suction tude connecting end 1 cylindrical setting has substituted getting ready of gas inlet seat ring 31 copper pipe 32 inner circles.The boss 2 of suction tude connecting end 1 can adopt punch process to obtain, and it makes very simple and convenient and low processing cost, without Specific Clamps, improves efficiency of assembling, reduces manually and drops into, and reduces costs; In addition after tested, the former linkage structure of getting ready in the copper pipe inner circle of gas inlet seat ring, the contact resistance of suction tude and gas inlet seat ring copper pipe is 0.47～0.50 Ω, and adopt this linkage structure, the contact resistance of suction tude and gas inlet seat ring copper pipe is 0.087～0.283 Ω, and known linkage structure effectively reduces contact resistance between the two, prevented the electric discharge phenomena of welding process, realize suction tude and be closely connected with gas inlet seat ring copper pipe, thereby guarantee compressor assembly quality.
