Abstract
The utility model discloses a threaded insert for an intake manifold of an engine. The threaded insert comprises a threaded insert body (1) and a flange (2) perpendicular to the axial direction of the threaded insert body (1), i.e., the axial cross section of the threaded insert is T-shaped, wherein the threaded insert has a hollow structure provided with through-holes in the axial direction of the threaded insert body (1); internal threads (3) are formed on the through-hole, and external threaded (4) are formed on the threaded insert body (1), the threading direction of the internal threads (3) are identical with that of the external threads and that of a bolt (5) fitted with the internal threads (3); and the threaded insert body (1) in the axial direction is 1mm to 2mm lower than a second flange (6) fitted with the threaded insert body (1) in the axial direction. The threaded insert having the special structure can solve the problems that the threaded insert is prone to slide or drop in the process for screwing the bolt and guarantee the performance enhancement of the engine in the early stage.
Description
Technical field
The utility model relates to a kind of threaded insert, especially relates to a kind of engine intake manifold threaded insert.
Background technique
The application of working of plastics on motor enlarges day by day, all the hardness owing to plastics is low for working of plastics of producing in enormous quantities such as intake manifold, valve chamber cover, oil sump etc., usually the mode that adopts hot pressing or cold pressing in the position of twisting bolt, allow on threaded insert or the steel bushing interference fit, can guarantee that bolt has enough screwing forces can guarantee that also inserts does not come off.But in the process of motor performance development in early stage, working of plastics generally adopts nylon material rapid shaping spare, can't be pressed into threaded insert by above method, cause threaded insert in the process of twisting bolt, to take place easily to slide or come off, cause engine component gas leakage, problems such as leakage of oil.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of engine intake manifold threaded insert at problems of the prior art, its objective is to solve in the bolt rundown process that threaded insert slides easily or problem such as come off, guarantee that the performance development in motor early stage carries out smoothly.
The technical solution of the utility model be this kind engine intake manifold with threaded insert comprise the threaded insert body and with the vertically disposed flange of threaded insert body axis direction, the axial cross section that is threaded insert is " T " font, described threaded insert is for being provided with the hollow structure of through hole along threaded insert body axis direction, through hole is provided with internal thread, and the threaded insert body is provided with outside thread.
Described internal thread is identical with externally threaded rotation direction, and consistent with the rotation direction of the bolt that matches with internal thread.
Described threaded insert body height in axial direction is less than second flange that matches with threaded insert body height 1-2mm in axial direction.
Being shaped as of described flange makes things convenient for fastening square head, five square toes, six square toes shapes.
A kind of engine intake manifold with above-mentioned special construction has the following advantages with threaded insert:
1, this kind engine intake manifold threaded insert is hollow structure and adopts internal and external screw thread, its thread rotary orientation is consistent with bolt, the flange of threaded insert one end band hexagon head or other form, when bolt is screwed into, utilize this this threaded insert of flange head fixed in shape, can not cause threaded insert to slide with bolt; When bolt is back-outed, utilize the externally threaded rotation direction on the threaded insert body consistent, and the position-limiting action of flange with bolt, guarantee that threaded insert can slippage and come off.
2, this kind engine intake manifold is easy to use with threaded insert, and reliable performance is simple in structure, is easy to realize.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is user mode figure of the present utility model.
In Fig. 1-2,1: the threaded insert body; 2: flange; 3: internal thread; 4: outside thread; 5: bolt; 6: the second flanges.
Embodiment
By the combination of structure shown in Fig. 1-2 as can be known, this kind engine intake manifold with threaded insert comprise threaded insert body 1 and with the vertically disposed flange 2 of threaded insert body 1 axial direction, the axial cross section that is threaded insert is " T " font, described threaded insert is for being provided with the hollow structure of through hole along threaded insert body 1 axial direction, through hole is provided with internal thread 3, threaded insert body 1 is provided with outside thread 4, internal thread 3 is identical with the rotation direction of outside thread 4, and consistent with the rotation direction of the bolt 5 that matches with internal thread 3; Threaded insert body 1 height in axial direction is less than the second flange 6 height 1-2mm in axial direction that matches with threaded insert body 1; Being shaped as of flange 2 makes things convenient for six fastening square toes shapes.
Certainly, the shape of flange 2 can adopt the fastening shape of any type of convenience, as: shapes such as square head, five square toes all can.
Concrete using process is: the outside thread 4 of threaded insert is tightened with second flange 6 put in place earlier, and guarantee that the bottom of threaded insert body 1 leaves the gap of 1-2mm apart from the top edge of second flange 6; Utilize tool wrench to fix six square toes flanges 2 again, bolt 5 is screwed in the internal thread 3 of threaded insert, to reach the purpose of clamping bolt 5.Simultaneously, when demounting bolt 5, adopt normal dismounting mode, can not carry out easily and do not need to fix six square toes flanges 2.
Claims (4)
1. engine intake manifold threaded insert, it is characterized in that: described threaded insert comprise threaded insert body (1) and with the vertically disposed flange of threaded insert body (1) axial direction (2), the axial cross section that is threaded insert is " T " font, described threaded insert is for being provided with the hollow structure of through hole along threaded insert body (1) axial direction, through hole is provided with internal thread (3), and threaded insert body (1) is provided with outside thread (4).
2. a kind of engine intake manifold threaded insert according to claim 1 is characterized in that: described internal thread (3) is identical with the rotation direction of outside thread (4), and with and the rotation direction of the bolt (5) that matches of internal thread (3) consistent.
3. a kind of engine intake manifold threaded insert according to claim 2 is characterized in that: described threaded insert body (1) height in axial direction is less than second flange (6) the height 1-2mm in axial direction that matches with threaded insert body (1).
