Technical Field

The utility model belongs to car wiper maintenance auxiliary assembly technique, concretely relates to wiper extracting tool.

Background

A truck windscreen wiper, such as a Shaanqi Orlon windscreen wiper and a Steyr windscreen wiper, mainly comprises a fixed arm and a scraping arm, wherein the fixed arm and the scraping arm are hinged, as shown in figure 4, the fixed arm is fixed on a base below a front stop of an automobile, a fixed seat is arranged on the base, a circular truncated cone section 10 of the fixed seat has a diameter which gradually increases from outside to inside to a diameter-fixing section 11, the fixed arm is sleeved on the circular truncated cone section and is tightened from the outside to the inside, and a threaded column extends out from the center of the fixed seat to be used for installing a nut.

The surface of the circular table section is provided with a plurality of ribs which are uniformly distributed in the circumferential direction and have the length directions of the inner direction and the outer direction, and a scraping arm of the windscreen wiper is sleeved on the circular table section to form tight fit.

Replacing the wiper:

1. when the wiper is not broken, the mode of dismantling the wiper usually is for twisting off the nut, and the arm is scraped to artifical handheld wiper, and the wiper is rocked on the limit, and the limit is toward pulling out outward, extracts the fixed arm from the round platform section gradually, and this operation is feasible, but comparatively hard, and dead time, when the fixed arm of meeting the wiper goes up mounting hole oxidation and threaded column adhesion, more can waste time, also changeing and lead to the fact the arm of scraping to damage.

2. When the windscreen wiper is broken, particularly when the fixed arm and the wiping arm are disconnected, the fixed arm is difficult to pull out by shaking due to the fact that the fixed arm is short.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will refer to the accompanying drawings to describe specific embodiments of the present invention. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.

Example 1

As shown in fig. 1-2, a wiper dismounting tool for improving the wiper dismounting efficiency specifically comprises an integrally formed U-shaped frame, wherein the U-shaped frame comprises a transverse plate 1, a left end plate 2 and a right end plate 3 which are fixed at two ends of the transverse plate, a screw rod 4 is in threaded connection with the left end plate, the right end of the screw rod extends between the left end plate and the right end plate, an opening 5 is arranged on the right end plate, and the opening extends downwards from the upper end of the right end plate.

During the use, through the open cover on the sizing section of fixing base, keep the screw rod to facing to the screw thread post, preferably keep screw rod and screw thread post coaxial line, twist and move the screw rod, the screw rod is close to the screw thread post, and when continuously twisting and moving the screw rod, one hand steady U-shaped spare, prevent its rotation, the screw rod is twisted to the other hand, the right-hand member of screw rod and the relative position of screw thread post are fixed, and the right-hand member of screw rod and the distance of right-hand member end plate are reducing, at this moment, the right-hand member board moves to the left along with the U-shaped spare is whole, come the change that adapts to the distance reduction between the right-hand member of screw rod and the right-hand member board, and drive the fixed arm and drop from the round platform section. Can pull down the fixed arm fast, save time, convenient operation improves maintenance efficiency.

Example 2

In embodiment 1, as shown in fig. 3, since the U-shaped element and the corresponding fixing seat are small in size, the head of the screw rod is small, and the screw rod is not easy to be stressed when being screwed by fingers, a polygonal hand-holding part 6 is fixed at the left end of the screw rod, so that the screw rod can be screwed in a hand-holding or grabbing state, and the operation is more convenient.

Example 3

In embodiment 1 or 2, because left end plate thickness is thin, thread length is short, influences life, and left end face or right-hand member face welded fastening at the left end plate install fixation nut, come the length of extension screw thread, at this moment, screw rod threaded connection fixation nut, and only need on the left end plate the through-hole supply the screw rod pass can, also need not to left end plate processing screw hole.

Example 4

In examples 1 to 3, the surface of the U-shaped frame was coated with a rust preventive layer.

Example 5

In the embodiments 1 to 4, the right end of the screw, that is, the front end, is a flat end, and the flat end is in surface contact with the left end of the threaded post, so that the resistance is large and the rotation is inconvenient, and therefore, the ball is embedded in the front end of the screw, and the contact area is reduced.

It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
