Description

The Wiper arm that can turn upside down

Technical field

The utility model relates to a kind of Wiper arm.

Background technology

Existing on the market Wiper arm is made up of rain brush seat, Wiper crank and the extension spring that is connected with its stage casing, the tension spring hook that is connected with the extension spring other end, brush away water droplet on the Windshield though adopt the Wiper arm of this structure can drive connected wiper bar, but tear open, shift gears wind glass or want before when turning over Windshield, because the Wiper arm retaining in front, it is bad that although Wiper arm does not have, also must be earlier with its dismounting, treat again it to be loaded onto again after maintenance is finished, so just increased the work capacity of maintenance.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, can turn upside down, the Wiper arm that can turn upside down of convenient for maintaining.

The utility model comprises rain brush seat, Wiper crank and the extension spring that is connected with its stage casing, the tension spring hook that is connected with the extension spring other end, refute between described rain brush seat and Wiper crank and be connected to pipe link, one end and the Wiper crank of pipe link are hinged, and the not end hook of tension spring hook firmly is loaded in its upper pin; The other end of pipe link and rain brush seat are hinged, its be provided with push rod in the rain brush seat is refuted the mortar that connects mutually, the rain brush seat offers the recess suitable with push rod on the corresponding position.

As a kind of improvement of the present utility model, the not end of Wiper crank is a flats, and is hinged with the wiper bar.

The utility model because adopt the rain brush seat and Wiper crank between refute the structure that is connected to pipe link, thereby have simple in structure, can turn upside down, the beneficial effect of convenient for maintaining.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The Wiper arm that can turn upside down shown in Fig. 1, Fig. 2, comprise rain brush seat 3, Wiper crank 1 and the extension spring 2 that is connected with its stage casing, the tension spring hook 8 that is connected with extension spring 2 other ends, 1 of described rain brush seat 3 and Wiper crank are refuted and are connected to pipe link 4, one end and the Wiper crank 1 of pipe link 4 are hinged, and the not end hook of tension spring hook 8 firmly is loaded in its upper pin 5; The other end of pipe link 4 and rain brush seat 3 are hinged, its be provided with push rod 6 in rain brush seat 3 is refuted the mortar that connects mutually, offer the recess 7 suitable on the rain brush seat 3 corresponding positions with push rod 6.

The utility model is like this work: when the recess 7 of 6 set of the push rod in the pipe link 4 in rain brush seat 3, pipe link 4 is subjected to spacing and can not rotates relative to rain brush seat 3; And be connected with extension spring 2 with below, the stage casing of its pivotally attached Wiper crank 1, hang with tension spring hook 8 between the bearing pin 5 on the other end of extension spring 2 and the pipe link 4; This kind state of the Wiper arm that can turn upside down is equivalent to traditional Wiper arm, can realize the function of brush rain; When needs overturn, suitably firmly just the push rod in the pipe link 46 can be pushed away the recess 7 in the rain brush seat 3, pipe link 4 at this moment just can rotate relative to rain brush seat 3, like this Wiper arm function of turning over after just realizing.

The Wiper arm that can turn upside down shown in Fig. 3 is a kind of improvement of the present utility model, and the not end of Wiper crank 1 is a flats, and be hinged with wiper bar 10, thereby wiper bar 10 can do 360 ° of rotations around the relative Wiper cranks 1 of bearing pin 9, and current when turning over Windshield, wiper bar 10 can do to rotate accordingly whole.

The Wiper arm that can turn upside down shown in Fig. 4, when after will tearing, shift gears wind glass open or wanting, turning over Windshield, as long as suitably firmly the push rod in the pipe link 46 is pushed away the recess 7 in the rain brush seat 3, just rain brush seat 3 overturning backward relatively of pipe link 4 of this moment, convenient for maintaining.When need using the function of traditional Wiper arm as long as suitably firmly the push rod in the pipe link 46 is resetted.

Claims
