The spray pipe is fixed by the tension spring when being positioned at the bottom of the extension arm, is fixed by the bending hole of the scraping rod when being positioned between the extension arm and the tail part of the scraping rod, is fixed by the clamp when being positioned at the middle part of the scraping rod, and is directly connected with the nozzle to be positioned when being positioned at the head part of the scraping rod, and the problem that the longer spray pipe is easy to droop is effectively solved by the multi-point fixing and positioning of the whole spray pipe. Thereby avoiding interference to the scraping and brushing process on the windshield and improving the cleaning effect of the glass scraping and brushing.
Description
Technical Field
The utility model relates to a wiper arm assembly applied to an automobile windscreen wiper.
Background
At present, a windscreen wiper (also called a wiper) is an indispensable part of an automobile, and the windscreen wiper is used for receiving power transmitted by a windscreen wiper motor and a connecting rod mechanism and generating wiper arm pressure at the same time, and the wiper rod drives a wiper blade to wipe a windshield, so that foreign matters on the glass are cleaned. The common wiper consists of a plurality of subassemblies, including a wiper motor, a linkage mechanism (comprising an output shaft), a wiper arm assembly, a wiper rod, a wiper blade, a motor mounting plate assembly and the like, and is also provided with a wiper water spraying device. The wiper arm assembly comprises a wiper arm head (also called a wiper joint), an extension arm, a wiper rod and the like, wherein the extension arm is connected with the wiper arm head through a combination of a tension spring and a pull hook, a spray pipe of the wiper water spraying device is connected with a nozzle arranged on the head of the wiper rod through the wiper arm head, the extension arm and the wiper rod in sequence, the fixing mode of the spray pipe is fewer, the phenomenon that the spray pipe easily sags due to no fixing point exists in the middle part of the spray pipe, and the spray pipe interferes with a wiper on a windshield, so that the cleaning effect of the wiper is seriously influenced.
Disclosure of Invention
The utility model aims to overcome the technical defects and provide the sagging prevention scraping arm assembly which can fix and position the water spray pipe and effectively prevent the water spray pipe from sagging.
The aim of the utility model is achieved by the following technical scheme: the anti-sagging wiper arm assembly comprises a wiper arm head, an extension arm and a wiper rod, wherein the bottom of the extension arm is provided with a tension spring and is connected with the wiper arm head through a pull hook, the bottoms of the wiper arm head, the extension arm and the wiper rod are provided with a spray pipe, the tail of the wiper rod is provided with a downward bending structure and is provided with a bending hole, the middle part of the wiper rod is provided with a clamp, the head of the wiper rod is provided with a nozzle, and the spray pipe sequentially penetrates through a middle through hole of the tension spring, the bending hole of the tail of the wiper rod and the clamp to be connected with the nozzle.
After the utility model is adopted, the spray pipe is fixed by the tension spring when being positioned at the bottom of the extension arm, is fixed by the bending hole of the scraping rod when being positioned between the extension arm and the tail part of the scraping rod, is fixed by the clamp when being positioned at the middle part of the scraping rod, and is directly connected with the nozzle to be positioned when being positioned at the head part of the scraping rod, and the problem that the longer spray pipe is easy to droop is effectively solved by the multi-point fixing and positioning of the whole spray pipe. Thereby avoiding interference to the scraping and brushing process on the windshield and improving the cleaning effect of the glass scraping and brushing.
Drawings
FIG. 1 is a schematic view of a sagging resistant arm module according to the present utility model.
Detailed Description
The utility model is described in detail below with reference to the drawings and the detailed description.
Referring to fig. 1, the anti-sagging wiper arm assembly for an automobile wiper according to the present utility model comprises a wiper arm head 7 (also called a wiper joint), an extension arm 6, and a wiper arm 3, wherein the bottom of the extension arm 6 is provided with a tension spring 5 and is connected with the wiper arm head 7 through a pull hook 8, the bottoms of the wiper arm head 7, the extension arm 6, and the wiper arm 3 are provided with a spray pipe 4, the tail of the wiper arm 3 is provided with a downward bending structure 9 and a bending hole 10 (in a shape of an elongated hole), the middle of the wiper arm 3 is provided with a clip 2 (several), the head of the wiper arm 3 is provided with a nozzle 1, and the spray pipe 4 sequentially passes through the middle through hole of the tension spring 5, the bending hole 10 at the tail of the wiper arm, and the clip 2 to be connected with the nozzle 1.
The water spray pipe 4 is fixed by a tension spring 5 (and a pull hook 8) at the bottom of an extension arm 6, is fixed by a bending hole 10 of a scraping rod when the extension arm is positioned between the extension arm and the tail of the scraping rod, is fixed by a clamp 2 at the middle of the scraping rod, is positioned by being directly connected with a nozzle 1 when the scraping rod is positioned at the head of the scraping rod, passes through the bending hole of the scraping rod, passes through a middle through hole of the tension spring, passes through a lower end hole of a wiper arm head 7 (namely, is positioned, and does not interfere with the cleaning condition of the scraping brush when the extension arm head is positioned at the bottom of the wiper arm head) so as to finish the fixation of the whole water spray pipe. Thereby effectively solving the problem that the longer spray pipe is easy to droop.
