Adjustable handle
Technical field
The utility model relates to a kind of print whitewash tool, particularly a kind of adjustable handle for whitewashing device.
Background technology
Rendering roller is a kind of print whitewash tool during existing life is produced, existing rendering roller in use, operating personnel whitewashes process by hand-held handle body head roll body to metope, and existing metope is stereochemical structure, the corner of metope is not easily whitewashed by barrel, needs to carry out secondary whitewashing by other print whitewash tools, substantially increase the workload of operating personnel like this, whitewash effect bad, improve production cost, the Practical Performance of rendering roller is low.
Refer to Fig. 1 (prior art), Fig. 1 is a kind of existing improvement print whitewash tool 10 '.Described print whitewash tool 10 ' comprises a brush 11 ', leader 12 ' and an angle disk 13 '.Described angle disk 13 ' is provided with a spring leaf 132 '.Described angle disk 13 ' is provided with several grooves, accordingly, described in described spring leaf 132 ' ends contact, rotating disk place is provided with a projection.When the projection on described spring leaf 132 ' embeds in described groove, described brush 11 ' can be fixed, reach and regulate and fix the object of brush 11 ' angle.When this print whitewash tool 10 ' uses, need the link pressing spring leaf and described rotating disk, to tilt the other end of described spring leaf 132 ', thus described projection is separated with groove; Then, rotate described rotating disk when sustained hold spring leaf, to regulate the angle of brush; Decontrol spring leaf again after adjustment, the projection on described spring leaf is embedded in described groove again, reaches the object of fixed angle.
In actual use procedure, aforesaid operations is very loaded down with trivial details, needs both hands to match incompatible operation.Meanwhile, the restoring force of Conventional springs sheet 132 ' is all comparatively strong, and this just needs larger pressing force.And, one end due to spring leaf 132 ' is bolted on described rotating disk, being very difficult by pressing this stiff end to tilt the projection of the other end, being difficult to the groove on the projection of spring leaf one end and rotating disc to be separated, cannot adjusting angle effectively.
Thus, the print whitewash tool of the improvement shown in Fig. 1 is due to the defect in structural design, and practicality is poor, not only cannot simplify and whitewash operation, can make complex procedures on the contrary.
Therefore, we need a kind of new print whitewash tool to overcome above-mentioned the deficiencies in the prior art, and this print whitewash tool Structure of need is simple and be convenient to one-handed performance.

Detailed description of the invention
Be described in detail the utility model below in conjunction with embodiment, embodiment is intended to explain and non-limiting the technical solution of the utility model.
Referring to Fig. 2, in the present embodiment, provide a kind of adjustable handle, whitewashing device for installing rendering roller formation.Described adjustable handle comprises: rendering roller mounting bracket 20, lever 30 and with angle regulator 40.Described rendering roller mounting bracket 20 is for installing rendering roller (not shown), and described lever 30 is for gripping, and described angle regulator 40 is for connecting described rendering roller mounting bracket 20 and described lever 30.Further, as shown in Figure 1, described angle regulator 40 is fixedly connected with by a first connecting rod 50 with described rendering roller mounting bracket 20; Described angle regulator 40 is fixedly connected with by a second connecting rod 60 with lever 30.
Please continue see Fig. 2 to Fig. 6, described angle regulator 40 comprises: one first rotating disk 42 and one second rotating disk 44.Described first rotating disk 42 being provided with a fixed part 422, for being fixedly connected with described first connecting rod 50, and then being fixedly connected with described rendering roller mounting bracket 20.Similarly, described second rotating disk 44 is fixedly connected with described second connecting rod 60, and then is fixedly connected with described lever 30.
Please continue see Fig. 2 to Fig. 6, described second rotating disk 44 comprises a rotating disk portion 442 and a junction 444.As shown in the figure, described first rotating disk 42 passes through pad 46 and a rivet 48 with the center of circle in the rotating disk portion 442 of described second rotating disk 44, relatively rotatably connects.Described connecting portion 444 is fixedly connected with described second connecting rod 60, it is arranged a locking button 446.Preferably, described rotating disk portion 442 is one-body molded with connecting portion 444.
As shown in Figure 6, as a non-limiting embodiment of the present utility model, one end of described spring 448 is fixed at the connecting portion 444 of described second rotating disk 44, and the other end then extends the inside of contact to the below of described locking button 446.When described locking button 446 moves to the direction of described lever 30 because of operating personnel's externally applied forces, described spring 448 is compressed, and 446, locking button and groove tooth 424 are separated.Now, the first rotating disk 42 can be adjusted to required angle.After adjustment completes, operating personnel can discharge locking button 446, and it moves to the direction deviating from described lever 30.Locking button 446 is anchored on groove tooth 424 by the deformation power that described spring 448 produces, thus locking the first rotating disk 42.
As shown in the figure, on described first rotating disk 42, circumferentially equidistant arrangement is provided with nine groove teeth 424, for matching with described locking button 446, with the first rotating disk 42 described in locking.
As shown in Fig. 7 A to 7C, during use, i.e. rotatable described first rotating disk 42 after described locking button 446 of pulling back, after adjustment angle, discharges described locking button 446 and can realize locking first rotating disk 42 and fixed angle.Specifically, when locking button 446 described in discharging, spring 448 as shown in Figure 6 can promote extruding locking button 446, is meshed with the selected groove tooth 424 on described first rotating disk 42 to make it enter selected position.Thus as shown in Fig. 7 A to Fig. 7 C, described locking button 446 locks the first rotating disk 42, and the first rotating disk 42 is made to be fastened on selected angle.
In the utility model, effective control of brush head angle can be realized by angle regulator, simultaneously by the mating reaction between each assembly, obtain the effect of one-handed performance.
Adjustable handle of the present utility model, by rational structural design, can realize one hand and complete angular adjustment and fixing function, greatly simplifie operation.
The utility model is described by above-mentioned related embodiment, but above-described embodiment is only enforcement example of the present utility model.Must it is noted that published embodiment limit scope of the present utility model.On the contrary, be contained in the spirit of claims and the amendment of scope and impartial setting to be included in scope of the present utility model.
