Abstract

The invention discloses a kind of elastic rake, it belongs to hardware apparatus field, and rake bar can be allowed to unclamp for it or collection is tight.It includes handle, bearing pin, link assembly, harrow bar, rake arms, there is each rake arms around the front end of the handle by pin shaft device, the front end of rake arms is all machined with prong, the stage casing of rake arms is all machined with the notch of left and right insertion, one left end is stretched into the right until a pin rod in connection movable in the notch on right side with the female bolt of butterfly from the notch in left side, rake bar position neighbouring in its back-end is all machined with the chute of one section of same longitudinal direction, one group and harrow the link assembly that matches of quantity of bar each pin of its lower end is all riveted to the rear end of each rake bar, each pin of link assembly upper end is then through riveting after the chute on each rake bar；The link assembly connected after each rake bar is placed between two rake arms, then two pins at link assembly two ends are respectively placed in pivot joint in the prong of rake arms front end.The design is applied to the cleaning to spot paster.

Description

Elastic rake

Technical field

The present invention is relevant with hardware ＆ tools, specifically refers to clear up the pine of paster advertisement lack of standardization in a kind of work for municipal administration Tight rake.

Background technology

The paster advertisement lack of standardization prohibited as psoriasis and removed incessantly without disappearing is one of municipal administration's cleaning work important Task, currently conventional method is usually that softening is first squirted with water, then strikes off cleaning with the sharp weapon of spade or hook rake, these works Have general shape fixing function single, such as, be required for possessing to improve operating efficiency both instruments：Between having etc. with cutting edge Scraped every every empty hook rake to make slubbing process to weaken the firm pasting degree of paster, then use cutting edge to be neat solid matter shape again Spade instrument carries out thorough cleaning and struck off, and size specification of poster paper etc. firm pasting degree that differs has by force and has weak, in reality This mode of operation of multiple types of tools its efficiency of needing to purchase is relatively low using being also inconvenient to be difficult to meet needs in work.

The content of the invention

The purpose of the present invention is the elastic rake of new technical scheme for providing a kind of rake, and it can solve foregoing ask Topic.

The content of technical solution of the present invention is as follows：It includes handle, bearing pin, link assembly, rake bar, rake arms, the handle Nearby there is each rake arms around its front end by bearing pin symmetrical mounting, and the front end of rake arms is all machined with prong, the stage casing of rake arms The notch of left and right insertion is all machined with, a left end stretches into the right notch with the female bolt of butterfly on the left of the notch in the rake arms in left side Be connected to until movable again in the notch of right side rake arms on a pin rod being installed on cell wall, bolt in two rake arms of left and right Between part also wear a spring to both sides stretching of ining succession；The rake bar is flat strip shaped, and position neighbouring in its back-end all adds Work has a chute of one section of same longitudinal direction, one group and harrows link assembly that the quantity of bar matches by each pin all rivetings of its lower end The rear end of each rake bar is connected to, each pin of link assembly upper end is then through riveting after the chute on each rake bar；Each rake will be connected Link assembly after bar is placed between two rake arms, then two pins at link assembly two ends are respectively placed in the prong of rake arms front end Interior pivot joint；Turn butterfly is female or just or the size of dehiscing of left and right rake arms will be adjusted for anti-rotation, that is to say drivening rod Component or being synchronized with the movement of elongating or shortening, also just have adjusted the spacing for each rake bar being connected on link assembly, reach or complete It is complete to be loosened or anxiety is closed up completely regulation purpose.

The beneficial effects of the invention are as follows：Each rake bar of rake can scatter or bunched according to operation needs, one-object-many-purposes, just Take and efficiently.

Brief description of the drawings：

Fig. 1 is the front view of the design rake（Bar is harrowed into the shape that scatters）.

Fig. 2 is the left side view of the design rake.

Fig. 3 is the use operation demonstration graph of the design different conditions.

In each figure, 1 is handle, and 2 be bearing pin, and 3 be notch, and 4 be pin rod, and 5 be rake arms, and 6 be prong, and 7 be link assembly, 8 It is rake bar for chute, 9,10 be that butterfly is female, 11 be bolt, and 12 is are eliminated thing, and 13 be harrow mark.

Embodiment：

The design is further illustrated below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the elastic rake of the design includes handle 1, bearing pin 2, link assembly 7, rake bar 9, rake arms 5, Nearby there is each rake arms 5 around the front end of the handle 1 by the symmetrical mounting of bearing pin 2, and the front end of rake arms 5 is all machined with prong 6, the stage casing of rake arms is all machined with the notch 3 of left and right insertion, and bolt 11 of the left end with butterfly mother 10 is from the groove in the rake arms in left side Mouthful left side is stretched into the right notch and is connected to until movable again in the notch of right side rake arms on a pin rod 4 being installed on cell wall, A spring to both sides stretching of ining succession also is worn in the part between two rake arms of left and right of bolt 11, spring can harrow left and right Arm is constantly strutted to both sides；Rake bar 9 is flat strip shaped, and position neighbouring in its back-end is all machined with the chute of one section of same longitudinal direction 8, one group and harrow the link assembly that matches of quantity of bar each pin of its lower end is all riveted to the rear end of each rake bar, connection rod set Each pin of part upper end then harrows riveting movable again after the chute 8 on bar through each, and link assembly 7 is exactly parallelogram connection-rod Component, as needed its connecting rod that can connect different length or varying number turn into the different combining structure of length, rake bar with After link assembly device as described above, the spacing of each rake bar can just occur with different change of link assembly or so width Change, this change procedure is also the change procedure that the pin in the chute 8 being installed on rake bar 9 is slided up and down in chute； The link assembly connected after each rake bar is placed between two rake arms, then two pins at link assembly two ends are respectively placed in rake It is pivotally connected in the prong 6 of arm front end, as shown in Figure 1 and Figure 2；When specifically used, turn butterfly mother 10 or just or anti-rotation will be to a left side The size of dehiscing of right rake arms is adjusted, and that is to say drivening rod component 7 or being synchronized with the movement of elongating or shortening, also just have adjusted The spacing for each rake bar being connected on link assembly, reaches to individual rake bar or loosely opens completely or the regulation closed up of anxiety completely Purpose, it is this design of each rake bar flexible operating deformation to be had many conveniences in specifically used, can be many with a thing With, when tackling wider paster for clearance or more difficult cleaning paster spot when rake bar can be scattered, and tackle smaller And easy to clean paster spot when can then be collapsed into the complete closed form of cutting edge, shape, is eliminated thing i.e. paster as shown in Figure 3 12 can clean out the strip harrow mark of shape such as 13 in the case where rake bar scatters（Cleaning face）, and the meeting in the case where rake bar is bunched Clean out the harrow mark of sheet（Cleaning face）13, it is a kind of useful improvement that cleaning device harrows bar.
