Description

The swivel joint of joint stable

Technical field

The utility model relates to auto parts machinery field, is specifically related to the swivel joint of joint stable.

Background technique

The motor of automobile can produce higher heat in the process of travelling, gas temperature in cylinder can be up to 1727～2527 ℃, if cooling not in time, to cause engine component excess Temperature, especially directly the part contacting with high-temperature gas, can affect normal matching gap because of expanded by heating, cause movement parts to be obstructed even stuck, in addition, high temperature also can cause the mechanical strength of engine component to decline, make lubricant oil ineffective, therefore in motor, be provided with cooling system, its cooling medium is cooling liquid, along with travelling of automobile, cooling liquid is because of the minimizing gradually of volatilization naturally of high temperature and the cooling system of motor, need regularly to supplement cooling liquid, because the opening of cooling liquid holding vessel is less, supplementing of cooling liquid is very not convenient, and by with the joints sleeve of leather hose on opening, can carry easily cooling liquid, it is unstable that but existing leather hose coordinates with joint structure, easily in course of conveying, there is leakage.

Summary of the invention

Technical problem to be solved in the utility model is to provide the swivel joint of joint stable, reasonable in design, simple in structure, manufacture easy, can make leather hose stably be fixed on joint, avoid the problem that cooling liquid leakage occurs because engaging in the insecure process carrying, operation is convenient, and sealing is strong.

For solving above-mentioned existing technical problem, the utility model adopts following scheme: the swivel joint of joint stable, comprise swivel joint housing, be located at the baffle ring at swivel joint housing middle part, be evenly located at swivel joint housing outer ring and be positioned at some first of baffle ring left side falling to encircle, the described first cross section that falls ring adopts triangle, and the described first inner side edge that falls to encircle is vertical with swivel joint housing; Described baffle ring is provided with bulge loop, and described bulge loop is parallel with swivel joint housing, is evenly provided with some second and falls to encircle on described bulge loop inwall, and the described second cross section that falls ring adopts triangle, and the described second inner side edge that falls to encircle is vertical with bulge loop.

As preferably, described first falls to encircle two of employings, described second falls to encircle three of employings, described first falls to encircle and the second setting of falling central spacer, ring and second is between ring during use, leather hose to be inserted to first, and first falls to encircle to limit leather hose inner side makes leather hose difficult mobile, and second falls to encircle to limit leather hose outside makes leather hose difficult mobile, can make leather hose stably be fixed on joint, avoid the problem that cooling liquid leakage occurs because engaging in the insecure process carrying.

As preferably, on described swivel joint housing and be positioned at bottom, baffle ring right side and be provided with annular groove, can act on when mounted on annular groove, avoid sliding hand, it is more convenient to make to install.

As preferably, the afterbody jointing of described swivel joint housing is provided with seal ring, can engage with the opening of cooling liquid holding vessel sealing more, avoids cooling liquid to spill from the opening junction point of joint and cooling liquid holding vessel.

As preferably, the front portion of described swivel joint housing is provided with fixed groove, leather hose pack into first fall ring fall to encircle with second between after, by additional cord, leather hose place corresponding to fixed groove pinioned, can further avoid leather hose to move.

Beneficial effect:

The swivel joint of the joint stable that the utility model employing technique scheme provides, reasonable in design, simple in structure, manufacture easy, can make leather hose stably be fixed on joint, avoid the problem that cooling liquid leakage occurs because engaging in the insecure process carrying, operation is convenient, and sealing is strong.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, swivel joint housing 1, annular groove 11, afterbody jointing 12, fixed groove 13, baffle ring 2, first encircle 3, bulge loop 4, second encircles 5, seal ring 6.

Embodiment

As shown in Figure 1, the swivel joint of joint stable, comprise swivel joint housing 1, be located at the baffle ring 2 at swivel joint housing 1 middle part, be evenly located at swivel joint housing 1 outer ring and be positioned at some first of baffle ring 2 left sides and encircle 3, described first encircles 3 cross section adopts triangle, and described first to encircle 3 inner side edge vertical with swivel joint housing 1; Described baffle ring 2 is provided with bulge loop 4, and described bulge loop 4 is parallel with swivel joint housing 1, is evenly provided with some second and encircles 5 on described bulge loop 4 inwalls, and described second encircles 5 cross section adopts triangle, and described second to encircle 5 inner side edge vertical with bulge loop 4.Described first encircles two of 3 employings, described second encircles three of 5 employings, described first encircles 3 and second encircles 5 intervals settings, on described swivel joint housing 1 and be positioned at baffle ring 2 bottoms, right side and be provided with annular groove 11, the afterbody jointing 12 of described swivel joint housing 1 is provided with seal ring 6, and the front portion of described swivel joint housing 1 is provided with fixed groove 13.

During real work, leather hose insertion first is encircled to 3 and second to be encircled between 5, first encircles 3 can limit leather hose inner side that leather hose is difficult for is mobile, second encircles 5 can limit leather hose outside that leather hose is difficult for is mobile, can make leather hose stably be fixed on joint, avoid the problem that cooling liquid leakage occurs because engaging in the insecure process carrying.

Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.

Although more used that swivel joint housing 1, annular groove 11, afterbody jointing 12, fixed groove 13, baffle ring 2, first encircle 3 herein, the term such as bulge loop 4, second encircles 5, seal ring 6, do not get rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
