Abstract
The utility model provides a drain plug of an automobile engine, which belongs to the technical field of automobile parts. The drain plug of the automobile engine resolves the technical problem that an existing drain plug of an automobile engine cannot remove ferric particles caused by abrasion of the engine. The drain plug of the automobile engine comprises a column head and a stud with an external thread structure which is fixed on the column head. An absorption structure is further arranged on the outer end face of the stud. The drain plug of the automobile engine has the advantages of being good in absorption effect and long in service life and the like.
Description
Technical field
The utility model belongs to technical field of automobile components, relates to the purge cock of a kind of purge cock, particularly a kind of motor car engine.
Background technique
In the automobile engine oil pan bottom one purge cock is housed all, be used to get rid of sediment and discharging machine oil, the quality of engine motor oil directly has influence on the working life of motor, especially because the iron particle that engine scuffing produces causes damage as can not in time clearing up very easily to motor.Existing purge cock such as Chinese patent disclose a kind of oil drain plug with lock (application number: 91201455.5) that is used for automobile and motor vehicle fuel tank, have screw rod and stud head, it is characterized in that also being provided with lock with backstop groove on the top of stud head, on lock and stud head, be set with the lock body that can rotate, the lockhole inboard of lock body be provided with lock on the dead bolt of backstop groove phase configuration.The oil drain plug of this patent disclosure can well seal up engine oil tank, but the iron particle that engine scuffing produces can't be cleaned out, so this patent can't solve the above problems.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of purge cock that can adsorb the motor car engine of fuel tank internal iron particle.
The purpose of this utility model can realize by following technical proposal: a kind of purge cock of motor car engine, comprise column cap and the double-screw bolt that is fixed on the column cap with external thread structure, and it is characterized in that, also be provided with adsorption structure on the exterior edge face of described double-screw bolt.
This purge cock is arranged on by being threaded in the drain oil of engine sump tank, by adsorption structure the iron particle in the oil sump is adsorbed, and these iron particles is cleaned out when fuel tank is drained the oil again.
In the purge cock of above-mentioned motor car engine, described adsorption structure is a magnet.By magnet the iron particle in the fuel tank is adsorbed.
In the purge cock of above-mentioned motor car engine, be fixed with a boss with mounting groove on the exterior edge face of described double-screw bolt, above-mentioned magnet is arranged in the mounting groove of boss.Design by such is installed in magnet on the double-screw bolt.
In the purge cock of above-mentioned motor car engine, the external diameter of described boss is less than the external diameter of double-screw bolt.Because the external diameter of boss is less than the external diameter of double-screw bolt, boss does not have screw thread, therefore can not block screw thread because of the too much iron particle of absorption, influences the working life and the dismounting of purge cock.
In the purge cock of above-mentioned motor car engine, described magnet by interference fit mode be fixed in the mounting groove of boss.
In the purge cock of above-mentioned motor car engine, described boss and double-screw bolt are integral structure.Make processing become convenient like this.
Compared with prior art, the purge cock of this motor car engine adsorbs the iron particle in the fuel tank by magnet by increase magnet on double-screw bolt, thereby improves the working life of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the utility model is installed in the structural representation on the engine sump tank.
Among the figure, 1, column cap; 2, double-screw bolt; 3, boss; 4, magnet; 5, fuel tank.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Embodiment one:
As shown in Figure 1, a kind of purge cock of engine sump tank comprises column cap 1 and the double-screw bolt with external thread structure 2 that is fixed on the column cap 1, at double-screw bolt 2 outer fixing one boss 3 is arranged, and offers mounting groove in boss 3, is provided with a magnet 4 in mounting groove.
Particularly, boss 3 is integrated by the mode of mould and double-screw bolt 2, and magnet 4 is fixed in the mounting groove of boss 3 by the mode of interference fit.The external diameter of boss 3 is less than the external diameter of double-screw bolt 2, because the external diameter of boss 3 is less than the external diameter of double-screw bolt 2, boss 3 does not have screw thread, therefore can not block screw thread because of the too much iron particle of absorption, influences the working life and the dismounting of purge cock.
As shown in Figure 2, this purge cock is to be installed in by being threaded in the drain oil of engine sump tank, by magnet 4 the iron particle in the fuel tank 5 is adsorbed, in discharging machine oil, this purge cock taken apart again the iron particle on the magnet 4 is cleaned out, thus the working life of improving motor.
Embodiment two
Content in the present embodiment two roughly with embodiment one in same content, different is that a kind of boss of embodiment 3 is integrated by the mode and the double-screw bolt 2 of mould, and in present embodiment two, boss 3 is to be fixed together by mode and the double-screw bolt 2 that welds.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes 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 this paper has used 1, column cap morely; 2, double-screw bolt; 3, boss; 4, magnet; 5, term such as fuel tank, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
