Description
Technical Field
The utility model belongs to the technical field of electric heater's technique and specifically relates to an undetachable inserts electric heater soon.
Background
At present, in order to solve the problem of icing of a crankcase ventilation pipe, each main engine plant is additionally provided with an electric heater between a crank pipe and an air inlet filter pipeline so as to solve the problem of icing and blocking of the crankcase ventilation pipe.
The connection mode of the heater is roughly divided into two types, one type is that the two ends of the heater are connected through rubber pipes and then clamped by a clamp, and the second type is that the heater is directly welded with an air filtering air inlet pipeline into an integral structure. The first solution, along with the tightening of the legislation, has been banned from use. The heater of the second scheme is welded with the air inlet pipeline, so that great waste is caused in the production process. The current structure has the defects that the scrappage of parts is high, and the whole air inlet filter assembly is scrapped due to the problem of a single part.
The utility model discloses the scheme is on the prerequisite that six regulations in state are approved, and the heater is strained with empty and is adopted fast to insert structural connection mode between the air inlet pipeline and realize.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the aforesaid provided, provide under the prerequisite that satisfies six regulations in state for the simple to operate of heater, a non-detachable inserts electric heater soon that cost of maintenance is low.
The purpose of the utility model is realized with the following mode: the utility model provides an undetachable inserts electric heater soon, has heater body, heating pipe, sealing washer and lock ring and constitutes, the sealing washer is installed it is spacing through the lock ring on the heater body, link through the fastening point between lock ring and the heater body.
The more optimized scheme is that the quick plug-in electric heater is not detachable, the fastening points are six and are distributed in the 180-degree direction, each side of the quick plug-in electric heater is three, and the three points are distributed in an isosceles triangle.
The more optimized scheme is that the non-detachable quick-plug electric heater is characterized in that the three points are an upper fastening point, a lower left fastening point and a lower right fastening point respectively, and the width of the upper fastening point is greater than the width of the lower left fastening point and the width of the lower right fastening point.
The most optimized scheme is the non-detachable quick-plug electric heater, the locking ring is opposite to the male joint, and the other end of the male joint is screwed on the air inlet filter pipeline through a bolt.
The more optimized scheme is a non-detachable inserts electric heater soon, the heating pipe is inserted in the hole of male joint, the last flange of male joint can be along the arcwall face of the locking card of lock ring, slowly struts two locking cards outwards.
The utility model has the advantages that: the utility model discloses a scheme structure is exquisite, and not only simple to operate, cost of maintenance is low, and the snap ring and this body coupling of heater are in the same place moreover, can prevent not hard up drop and rotation, also guarantee the undetachable of heater simultaneously, have improved the availability factor of product.
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the heater configuration;
fig. 3 is a schematic view of the locking ring.
The specific implementation mode is as follows:
referring to fig. 1, 2 and 3, the non-detachable quick-plug electric heater comprises a heater body 1, a heating pipe 2, a sealing ring 3 and a locking ring 4, wherein the sealing ring 3 is mounted on the heater body 1 and limited by the locking ring 4, and the locking ring 4 is connected with the heater body 1 through a fastening point.
The fastening points are six and distributed in the 180-degree direction, three are arranged on each side, and the three points are distributed in an isosceles triangle shape. The three points are an upper fastening point 41, a lower left fastening point 42 and a lower right fastening point 43, respectively, and the width of the upper fastening point 41 is greater than the width of the lower left fastening point 42 and the width of the lower right fastening point 43. The clamp ring with the structure is tightly connected with the body in a mode of loosening, falling off and rotating.
The locking ring 4 faces the male connector 5, and the other end of the male connector 5 is screwed on the air intake filter pipeline 6.
The heating tube 2 is inserted into the inner bore of the male fitting 6, while the locking clip 44 has a guiding effect on the installation of the male fitting 5. With electric heater complex male joint 5 (accord with SAE J2044), when electric heater installs the male joint 5 on the air filter pipeline 6 of admitting air, heating pipe 2 inserts in the hole of male joint 5, the flange on male joint 5 can be along the arcwall face of the locking card 44 of lock ring 4, slowly strut two locking cards outwards, cross the top surface of locking card 44 when the flange of male joint 5, locking card 44 tightens up to the inboard under self structure, the top surface of locking card 44 tightly withstands the flange lower surface on the male joint 5 this moment, male joint 5 on the air filter pipeline 6 is tightly fixed together through lock ring 4 and male joint 5, can't dismantle.
The working principle is as follows: the locking ring 4 is fixed with the heater body 1 through six points on the locking ring 4 and six holes on the heater body 1, the six points are distributed on two sides of the locking ring 4 at 180 degrees, three points on each side are distributed in an isosceles triangle shape, and two points below the upper point are distributed. When the electric heater is installed on the air filtering pipeline 6, the heating pipe 2 of the heater is inserted into the inner hole of the male joint 5; the flange of the male connector 5 pushes the locking piece 51 of the lock ring 4 outward, and when the flange of the male connector 5 goes beyond the top surface of the locking piece 44 on the lock ring 4, the locking piece 44 contracts inward, and the top surface of the locking piece 44 abuts against the lower surface of the flange of the male connector 5, so that the male connector 5 cannot fall off. So install electric heater on empty male joint 5 who strains pipeline 6, realized non-detachable function, reduced the rejection rate and the cost of maintenance of product when having simplified the structure, really realized non-detachable effect.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
