Description

Technical Field

[0001] This utility model relates to the field of wiper blade rubber strip insertion into the frame, and more particularly to a wiper blade rubber strip insertion into the frame device. Background Technology

[0002] There are generally two types of windshield wipers: framed wipers and frameless wipers. The wiper blade itself is the functional part. Frameless wipers are assembled by inserting springs into both sides of the rubber blade and securing it with a clip. The advantage of this type of wiper is its low price, but it tends to become less effective at wiping after a period of use. Framed wipers, on the other hand, insert and fix the rubber blade into a flexible frame. The advantage of this type is its longer service life and better performance. However, when installing the rubber blade into the frame, because rubber is easily deformed, it is difficult to operate with machinery. We use manual installation. Since the frame is curved and the rubber is soft, installation is relatively troublesome. Therefore, to facilitate installation, we designed a device to assist in inserting the wiper blade into the frame. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a wiper blade rubber strip auxiliary insertion device, including a mounting base, a rubber strip groove, and a frame clamping and opening guide block; the mounting base is provided with a rubber strip groove, the depth of the rubber strip groove is less than the height of the rubber strip, and a frame clamping and opening guide block is provided at one end of the rubber strip groove, the side of the frame clamping and opening guide block away from the rubber strip groove is semi-elliptical.

[0004] The rubber strip groove consists of adjustment blocks on both sides. One side of the adjustment block is set inside the adjustment device, and the other side of the adjustment block abuts against the mounting plate. The mounting plate is fixed on the mounting base, and the skeleton clamping guide block is installed on the mounting plate.

[0005] The width of the skeleton clamping guide block is 1-2 mm wider than the width of the rubber strip groove.

[0006] The mounting plate and the upper end of the mating side of the adjusting block are provided with mounting grooves. The skeleton clamps the guide block and the two sides are provided with mounting ear plates. The mounting ear plates and the mounting grooves are matched and installed. The two ear plates are fixed by bolts on the edge side.

[0007] The adjusting device includes a fixed base, limiting rods, and an adjusting screw. The fixed base is a groove structure with openings facing each other. Two adjusting blocks extend into the groove of the fixed base. Limiting rods are horizontally arranged on both sides of the groove of the fixed base, passing through the groove and the adjusting blocks. The two adjusting blocks can slide back and forth on the limiting rods. An adjusting screw is horizontally arranged between the two limiting rods. The two ends of the adjusting screw are rotatably limited on the fixed base. The threads on both sides of the adjusting screw in the groove of the fixed base are opposite. The adjusting screw passes through the adjusting blocks on both sides and is threadedly engaged with them. One end of the adjusting screw passes through the fixed base and is connected to a rotating knob.

[0008] The beneficial effects of this utility model are as follows:

[0009] Workers can quickly complete the installation by placing the adhesive strip into the adhesive strip groove and then horizontally pushing the frame along the elliptical end of the guide block that opens the frame clamp. This solves the problems of the adhesive strip being soft and the frame being bent, making installation difficult. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Fig. 1 , 2 This is a schematic diagram of the present invention.

[0012] Fig. 3 This is an enlarged schematic diagram of the present invention. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] See Figs. 1-3 .

[0015] This utility model discloses a wiper blade rubber strip insertion auxiliary device, including a mounting base 1, a rubber strip groove 2, and a frame clamping and opening guide block 3; the mounting base is provided with a rubber strip groove, the depth of the rubber strip groove is less than the height of the rubber strip, the protruding part of the rubber strip inserted into the rubber strip groove is a clamping part, and a frame clamping and opening guide block is provided at one end of the rubber strip groove, the side of the frame clamping and opening guide block away from the rubber strip groove is semi-elliptical.

[0016] The rubber strip groove is composed of two adjusting blocks 4 on both sides. One side of the adjusting block is set in the adjusting device, and the other side of the adjusting block abuts against the mounting plate 5. The mounting plate is fixed on the mounting base, and the skeleton clamping guide block is installed on the mounting plate.

[0017] The width of the skeleton clamp opening guide block is 1-2mm wider than the width of the adhesive strip groove. When the adhesive strip is placed in the adhesive strip groove, although it fits against the skeleton clamp opening guide block, the adhesive strip is relatively soft, and even if it fits, there will still be gaps. Therefore, if the width of the skeleton clamp opening guide block is the same as the width of the adhesive strip groove, it will be very easy to get stuck when the skeleton clamp is pushed in from one side of the skeleton clamp opening guide block. Therefore, widening it by 1-2mm as a transition will prevent this from happening.

[0018] The mounting plate and adjusting block have mounting grooves 6 on their upper mating sides. Mounting ear plates 7 are provided on both sides of the frame clamping guide block 3. The mounting ear plates and mounting grooves are matched and installed, and the two ear plates are fixed to the edge side by bolts 8. The detachable frame clamping guide block 3 can be replaced with different sized frame clamping guide blocks 3 according to different rubber strip models, thereby achieving an effect 1-2mm wider than the rubber strip groove.

[0019] The adjustment device includes a fixed base 9, a limiting rod 10, and an adjusting screw 11. The fixed base has an opening-facing groove 12 structure. Two adjusting blocks extend into the groove of the fixed base. Limiting rods are horizontally arranged on both sides of the groove of the fixed base, passing through the groove and the adjusting blocks. The two adjusting blocks can slide back and forth on the limiting rods. An adjusting screw is horizontally arranged between the two limiting rods. The two ends of the adjusting screw are rotatably limited on the fixed base (the limiting method can be any existing technical structure that can achieve the effect, such as bearings). The threads on both sides of the adjusting screw in the groove of the fixed base are opposite. The adjusting screw passes through the adjusting blocks on both sides and engages with them threadedly. One end of the adjusting screw passes through the fixed base and is connected to a rotating knob 13. Because the threads on both sides of the adjusting screw are opposite, when adjusting the rubber strip groove, rotating the rotating knob 13 can make the adjusting block 4 open outward or retract inward simultaneously.

[0020] Specific operations

[0021] First, according to the wiper model, turn the knob 13 to make the width of the rubber strip groove just right to fit the rubber strip. At the same time, fix the frame clamp and guide block 3 on the other side and you can start the auxiliary installation. First, put the rubber strip into the rubber strip groove. The worker picks up the frame and pushes the rubber strip clamp of the frame into the elliptical end of the frame clamp and guide block 3. While pushing it in, the worker should also press the bent frame down to make it relatively straight, and then quickly push in the rubber strip. One wiper is now installed.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
