Abstract

The utility model relates to a wiper replacement sheet, which is mainly characterized in that a plurality of slotted holes are punched downwards on the side wall of a slide opening of wiper rubber embedded at the rear end of a wiper rubber supporting sheet, so that a punched block protrudes into a slide to form a barb-shaped body, and a matching groove is cut on an embedded bottom block of the wiper rubber; after the embedded bottom block of the wiper rubber slides into the slide way of the supporting sheet, the inverted hook body protruded from the slide way by the slot hole makes the bottom block slide into it and can not be pulled out, so that the wiper rubber will not fall off. By this structure, the whole set of replacement blades can be tailored to different windshield wiper supports required by different vehicles, thereby achieving convenient effect.

Description

The utility model relates to a wiper replacement sheet. The wiper rubber can be firmly combined with the wiper support sheet without falling off easily. At the same time, it can be cut according to the requirements of different wiper brackets, and has a very practical effect.

The wiper replacement piece composed of the rubber support piece of the wiper used in automobiles and the wiper rubber can be shown in Figure 1, which is wedged by the square groove 21 of the wiper rubber support piece 2 and the bump 11 of the wiper rubber 1. , and at the end of the wiper rubber support piece 2, a fixed-end blocking clip 3 is provided, wherein the blocking piece 31 stops at the end of the slideway of the support piece, and rushes down on the other side where the other end is wedged with the wiper rubber A concave slot 23 to complete the bonding. Or in the situation shown in Fig. 2, be to clamp the other end of rubber supporting sheet 2 into flat shape, to form sealing 24, make two brushes rubber 1 can not come off. In the fixing methods formed by these two methods, the wiper rubber 1 often falls off, mainly because the contact surface for resisting the sliding of the wiper rubber is too small, and the resistance is easy to loosen.

Furthermore, the above-mentioned commonly used combination structure is quite complicated to manufacture, wastes manpower and time, and is not in line with economic benefits. At the same time, after the structure of the above-mentioned wiper replacement piece is manufactured, the length of the wiper support piece is fixed and cannot be cut again. However, the wiper brackets of general automobiles may have different lengths, so it is very inconvenient to assemble and match. All of these are structural defects of the commonly used wiper blades.

Therefore, the main purpose of this utility model is to provide a wiper replacement piece, which can utilize the barb block in the slot hole on the side wall of the slideway, so that the wiper rubber can only be inserted from the outside of the slideway, and cannot be pulled out. , so that the structure of the entire set of replacement sheets is stable, and the wiper rubber will not fall off.

Another purpose of this utility model is to provide a wiper replacement sheet. Since the end of the wiper rubber is fastened to the support sheet, the open end of this wiper replacement sheet can be cut freely, and can be customized according to different wiper brackets. It is considerably convenient to use.

According to the utility model, a wiper replacement piece includes a wiper rubber support piece, a wiper rubber and an end resistance piece; wherein the wiper rubber support piece has a slideway, and a slideway opening is formed above it, so that the bottom has a "shi"-shaped embedded The wiper rubber of the body can be inserted and fitted; in addition, the end resistance piece is fastened to one end of the wiper rubber support piece, and the stop piece is to stop at the end of the slideway, so that the embedded wiper rubber will not slip from it, and the end resistance piece has A pair of half arrow bodies, which can be combined with the car wiper bracket; it is characterized in that:

Among them, one side end of the support piece slideway and the end resistance piece is connected, and on the opposite side wall of the slideway opening, a plurality of slot holes are stamped at an oblique angle, so that a barb-shaped protrusion protrudes into the slideway opening after stamping. body, and the barb-shaped body punched out oppositely forms a necked part in the opening of the slideway; in addition, on the embedded part of the rubber bottom of the wiper, it is cut at a position matching the slot punched obliquely from the opening of the slideway. There are grooves, so that when the embedded part of the wiper rubber is inserted into the slideway, the slot hole is just located between the grooves; when the wiper rubber is inserted into the slideway, it can slide smoothly through this part in front of the embedded part by using the elasticity of the rubber. Neck part: When the embedded part is positioned and the groove is included in the slot hole, the wiper rubber can no longer slip out of the support piece due to the narrow path formed by the neck part.

Below, according to the embodiment of the utility model shown in the accompanying drawings, the structural features and functions of the utility model are described in detail. Among them, each accompanying drawing is briefly explained as follows:

Figure 1 shows one of the commonly used wiper replacement sheets;

Figure 2 shows the second commonly used wiper replacement piece;

Fig. 4 is a partially enlarged cross-sectional view of the support sheet of the utility model wiper replacement sheet;

Fig. 5 is a partial top view of the slotted hole of the support sheet of the utility model wiper replacement sheet;

Fig. 6 is a partial top sectional view of the slot hole of the support sheet of the wiper replacement sheet of the present invention, wherein the imaginary line represents the wiper rubber;

Figure 7 is a combined side view of the utility model wiper replacement sheet.

Please refer to FIG. 3 , the wiper replacement sheet of the present invention includes a wiper rubber support sheet 2 , a wiper rubber 1 and an end resistance sheet 3 and other components. Wherein the wiper rubber supporting sheet 2 has a slideway 25, and a slideway opening 251 is formed above it, so that the wiper rubber 1 with the "士" font embedded body 11 at the bottom can be inserted and fitted, and is the combined state shown in Figure 4 . In addition, the end resistance piece 3 is fastened to one end of the wiper rubber support piece 2, and its retaining piece 31 stops at the end of the slideway 25, so that the embedded wiper rubber 1 will not slip off from here, and the end resistance piece 3 has a pair of half Arrow body 32, and can be combined with automobile windshield wiper bracket.

As shown in Fig. 3, one of the side ends where the slideway 25 of the support piece 2 is connected with the end resistance piece 3, on the opposite side wall 252 of the slideway opening 251, several slots 26 are punched at an oblique angle, so that after punching A barb-shaped body 261 protrudes into the slideway opening 251, which is depicted in detail in FIG. 4 , and on the top view shown in FIG. A necking part 253 is formed in the slideway opening 251; in addition, on the embedded part 11 at the bottom of the wiper rubber 1, a groove 12 is cut out at the matching position with the slotted hole 26 obliquely punched out by the slideway opening 251, so that the wiper When the embedding part 11 of the rubber 1 is inserted into the slideway 25, the slot hole 26 is just located between the grooves 12, as shown in FIG. 6 .

Therefore, in the above-mentioned structure, the barb-shaped body 261 forms the constricted part 253, so that when the wiper rubber 1 is inserted into the slideway 25, it can slide smoothly in front of the embedded part 11 by utilizing the elasticity of the rubber. A constricted part 253 ; when the embedded part 11 is positioned and the groove 12 is included in the slot hole 26 , the wiper rubber 1 cannot slip out of the supporting sheet 2 due to the narrow path formed by the constricted part 253 .

The wiper replacement sheet composed of this structure, because the fixed position is close to the end resistance sheet 3, and the other end is free and loose, so the whole set of replacement sheets can be combined with the car wiper bracket At the same time, its length can be cut according to different wiper brackets, so it has versatility in sales, and does not need to be manufactured in a fixed length standard, which is better than the traditional one; at the same time, it can be combined with several slots. The wiper rubber is resisted and fixed one by one, and its natural structure is stronger than the traditional one.
