Description

Water scraper

Technical Field

The utility model relates to a manual burnisher field indicates a domestic wiper of scraping head and stalk portion equipment connection very much.

Background

The wiper is a daily cleaning tool for cleaning accumulated water on the ground, glass and the like, mainly comprises a wiping head and a handle part, wherein the wiping head is provided with a wiping strip connected with the wiping head, and the wiping strip is generally an adhesive tape and is fixed through a support.

At present, most of the scraping heads are metal products, the handle parts of the scraping heads are generally formed by metal encapsulation, namely, a layer of handle formed by rubber materials is coated on the metal handle, the finished product of the encapsulated handle generally needs to be subjected to the working procedures of heating, vulcanizing, cooling, trimming and the like, the production process is time-consuming and very high in difficulty, if a certain working procedure is not controlled well, the adhesion between the scraping heads and the encapsulated handle is poor, and the overall quality of the product is difficult to guarantee. In addition, after the wiper adopting the rubber-coated handle is repeatedly used, the rubber-coated part of the handle part of the wiper head is easily peeled off, and the connection is unstable due to looseness, and even the rubber coating is cracked or damaged from inside to outside.

Disclosure of Invention

The utility model discloses an aim at solving above-mentioned wiper scrape the head rather than the connection technology between the rubber coating handle loaded down with trivial details, consuming time, insecure and use and appear bursting or damaged scheduling problem easily, provide one kind through the equipment mode to scraping the wiper that head and handle are connected.

In order to achieve the above purpose, the utility model discloses a: scrape head and handle, the upper and lower surface of the handle end of scraping the head is equipped with top board, the holding down plate of hugging closely with it respectively, should go up, the holding down plate with all be equipped with the hole groove of mutual embedding, lug structure between the handle end, the one end of handle is equipped with the slot that the handle end, top board and the holding down plate that supply to scrape the head put into together, all is equipped with catching groove, the convex part structure of fastening each other between the inner wall of this slot and upper and lower holding down plate.

The technical scheme adopts a plurality of accessories to be combined, thereby realizing the assembly connection of the scraping head and the handle, when the two are assembled, the upper and lower pressing plates are simultaneously attached to the upper and lower surfaces of the handle end of the scraping head, and the slotted holes and the lugs between the upper and lower pressing plates are utilized to carry out embedding connection, thereby carrying out pre-positioning, preventing the upper and lower pressing plates from slipping on the surface of the handle end, then inserting the upper and lower pressing plates into the slot of the handle together, and until the inner wall of the slot and the lower pressing plates, the buckling grooves and the lugs between the upper pressing plates are mutually fastened, the whole assembly process is convenient and rapid, the connection between the scraping head and the handle is firmer, the scraping head and the handle is not easy to damage, various product quality problems in the process of the encapsulation process can be avoided, and the production efficiency and the yield are improved.

Furthermore, the handle end, the upper pressing plate, the lower pressing plate and the slot of the handle of the scraping head are all in matched arc shapes. The arc-shaped connecting components can form mutually limited arc-shaped coating surfaces among the connecting components, so that the stress area among the components is increased, particularly the two side surfaces, the abrasion degree of the inner wall of the handle is effectively reduced, and the connecting is more stable and firm.

Furthermore, the handle end surface of the scraping head is provided with at least one hole groove penetrating through the surface of the scraping head, and the upper pressing plate and the lower pressing plate are respectively provided with a convex block correspondingly embedded into the hole groove. The slotted hole enables the handle end of the scraping head to form a perforated structure, the front surface and the back surface of the slotted hole can be simultaneously embedded by the lugs of the upper pressing plate and the lower pressing plate, so that the handle end of the scraping head is more easily aligned with the edge between the upper pressing plate and the lower pressing plate, the deviation rate of the whole handle and the slot connection of the handle is reduced, and the handle can be smoothly placed into the slot.

Furthermore, a guide rail and a sliding groove structure which are mutually matched are arranged between the upper pressing plate and the upper inner wall of the slot, and are respectively positioned on the same straight line surface with the buckling groove and the convex part. The guide rail and the sliding groove can enable the handle end of the scraping head and the upper and lower pressing plates to be integrally and smoothly inserted into the slot of the handle and fastened, and meanwhile, a guide mounting structure is formed at the upper part of the guide rail and the sliding groove, so that the alignment work during assembly is saved, and the assembly efficiency is improved.

Furthermore, the tops of the opposite arc surfaces between the lower pressure plate and the lower inner wall of the slot are planar, so that the lower pressure plate and the lower inner wall of the slot form a rail and chute structure which are matched with each other integrally. The lower inner wall of preforming and slot under this department passes through between arc surface and its plane cooperation, makes the two both sides form bight, can further restrict the sideslip space of preforming down, strengthens the steadiness of connecting, and simultaneously, the lower inner wall of preforming and slot constitutes track, the spout structural relation of mutually supporting down, has both played the effect of lower part direction installation, helps smoothly again to insert the connection in the same direction.

Furthermore, a groove surface is arranged on the clinging surface of the lower pressure plate and the handle end of the scraping head. The groove surface can increase the facing tightness between the lower pressing plate and the handle end of the scraping head, so that the lower pressing plate and the handle end of the scraping head are connected more integrally and more firmly.

Compared with the prior art, the utility model discloses utilize interference connection relation and embedding, hasp structure between each subassembly, make to scrape the connection between head and the handle firm more and durable, more convenient and fast during the equipment, simultaneously, also can save production time, improve the yield and the quality of product.
