Detailed Description

Referring to fig. 1, a seat adjustment handle includes a handle body 20 connected to an end of a rotating shaft 10, the handle body 20 is sleeved with a handle sheath 30, and the seat adjustment handle is characterized in that: the handle body 20 is formed by the lath punching press and the protruding muscle or the recess on the face arranges along the long direction of handle, the handle body 20 on have indentation 21 along its length direction's border, the inner wall of handle sheath 30 corresponds the position department and is provided with the convex part 31 that is used for embedding indentation 21.

The scheme is set for realizing convenient connection of the handle rod body 20 and the handle sheath 30, namely, a sleeve cavity of the handle sheath 30 aligns with the handle rod body 20 during assembly and then is plugged in, and at the end of a plugged stroke, the positions of the concave part 21 and the convex part 31 just face to each other to form mutual clamping and embedding, so that the assembly is convenient, the connection is stable and reliable, under the action of no external force interference, the clamping and embedding state of the concave part 21 and the convex part 31 is basically maintained, namely, under the normal use state, only the external force action of moving the handle sheath 30 is needed, and the independent external force action of separating and moving for driving the concave part 21 and the convex part 31 to separate from each other along the direction vertical to the length direction of the handle rod body is avoided. The arrangement of the convex ribs or the grooves on the handle body 20 in the above scheme can effectively improve the bending strength and the torsional strength of the handle body 20, and does not need to increase too much material cost.

Preferably, the indentation 21 is disposed on the upper edge of the handle body 20, and under the condition that the indentation 21 and the boss 31 of the handle sheath 30 are mutually engaged, the boss 31 of the handle sheath 30 is under the action of the gravity of the handle sheath 30, and the boss 31 of the handle sheath 30 and the indentation 21 of the handle body 20 are more tightly attached, are not easy to slip, and are more stably and reliably mounted.

The handle sheath 30 is tubular or trough-shaped. The two sleeve cavities can be sleeved with the handle rod body 20, namely, the tubular or groove-shaped sleeve cavity of the handle sheath 30 is used for the handle rod body 20 to penetrate into the handle sheath 30 along the pipe length or groove length direction, and after the two sleeve cavities are inserted and sleeved, the possibility of separation does not exist in the direction vertical to the pipe length or groove length, so that the mutually clamped and embedded matching of the concave part 21 and the boss 31 is maintained.

Preferably, the handle sheath 30 is a tubular shell, and the upper edge of the rear part of the middle section of the handle body 20 is provided with a concave part 21. The structural form of the tubular sleeve cavity is selected, so that the handle sheath 30 can be ensured to completely sleeve the handle rod body 20 with proper length in the handle sheath 30, and the comfort degree of holding the handle sheath 30 is ideal during handling operation. The upper edge of the rear part of the middle section of the handle rod body 20 is provided with the concave part 21, the interference between the inner wall of the sleeve cavity and the handle rod body 20 can be avoided in the assembling process of the insertion of the concave part and the handle rod body, and only when the insertion stroke is finished, the concave part 21 and the boss 31 are just positioned at the position to be matched.

It should be noted that when the handle sheath 30 is a trough-type shell-shaped structure, the notch of the trough cavity is also in a closed shape, so as to avoid the possibility of loosening or separating the two along the direction perpendicular to the insertion direction, and meanwhile, the notch of the closed slot should be arranged downward, and the comfort in holding the handle should be ensured. Of course, this solution can save material for the handle sheath 30.

The handle body 20 has a narrow front section and a wide rear section, and the handle sheath 30 has a lumen with a narrow front section and a wide rear section. As shown in the figures 1-4, the handle rod body 20 and the handle sheath 30 in the shapes of the scheme have the advantages that the structural strength requirement and the hand-held comfortable feeling requirement are met in the moving process, and particularly the mutual interference phenomenon is reduced in the assembling process of the insertion connection of the handle rod body and the handle sheath.

Preferably, the convex portion 31 provided on the inner wall of the top of the handle sheath 30 is a protruding strip with a cross section in a trapezoid shape with a large upper bottom and a small lower bottom, and the length direction of the strip is perpendicular to the length direction of the lumen of the handle sheath 30; correspondingly, the indentation 21 of the handle body 20, which is engaged with the protrusion 31, is in the shape of an open-ended notch with a large opening and a small bottom, and the upper arcs of the front and rear side walls transition to the upper plate edge of the handle body 20, so that the included angle between the front waist side and the upper bottom of the protrusion 31 is larger than the included angle between the rear waist side and the upper bottom, and the inclination angles of the front waist side of the protrusion 31 and the front side wall of the indentation 21 are the same. In the scheme, the convex part 31 slides into the area of the concave part 21 when the assembly is convenient, and the stable and reliable anti-falling effect formed by matching the convex part and the concave part can be ensured.

The convex part 31 is positioned at an exposed window 32 formed on the side wall of the inner shell of the handle sheath 30, and a partition 33 is arranged from the window 32 to the front end of the handle sheath 30 so as to divide the strip-shaped hole into unit holes 34. In the scheme, the exposed window 32 and the strip-shaped holes are formed to reduce the weight of the handle sheath 30 and reduce the use of materials, and the partition plates 33 are arranged between the strip-shaped holes to reduce the materials and increase the bending resistance and torsion resistance of the handle sheath 30.

The utility model discloses in, the position department that the handle pole body 20 and pivot 10 worn the even has the radials 22 along the radial extension of pivot, and the spacing post 41 that sets up on the connecting plate 40 that links to each other with the seat body is protruding to the angular form region between radials 22 and the handle pole body 20 in, and on radials 22 and connecting plate 40 were do not rolled over respectively to the both ends of the torsion spring 50 that the cover was established in the pivot 10, the elasticity that torsion spring 50 provided orders about radials 22 and handle pole body 20 synchronous rotation to radials 22 and spacing post 41 contact cooperation.

In the above scheme, the excessive problem that resets of torsional spring 50 has been solved in setting up of spacing post 41, adopts torsional spring 50 both to avoid traditional extension spring's abnormal sound problem that resets, can alleviate the volume of rocking of handle pole body 20, and the required working space of extension spring is great, has reduced device moving space.
