Background technology

Integrated kitchen range generally is designed to the casing shape, cover on this casing and be fixed with the electronic striking kitchen range, when cleaning, maintenance, maintenance, need utilize strut to strut to make things convenient for the staff to clean, keep in repair, maintain, traditional strut is a straight-bar, its height is certain, can't regulate height again once strut, and when cleaning, maintenance, maintenance, the angle that people need regulate the sparking kitchen range needs the place of cleaning, keep in repair, maintaining with convenient manual can touching suitably, and present strut can't be accomplished.

The utility model content

The purpose of this utility model is to provide a kind of step positioning type automatic strut, it can play the function of regulating height, when cleaning, maintenance, maintenance, can open like a cork, and adjusting is highly convenient, and can touch the place that needs to clean, keep in repair, maintain suitably carries out work by hand.

For achieving the above object, technology solution of the present utility model is as follows:

The automatic strut of step positioning type, it is made up of expansion link, loop bar, wearing piece, hook sheet, spring, gear post, form convex tendon on the expansion link, this convex tendon matches with anterior two projectioies and forms spacing space, and the wearing piece front portion is fastened between two projectioies and drops in the spacing space; The hook sheet of buckle portion is housed in the receiving space that matches on the expansion link, and spring one end active force is in the hook sheet, and the other end acts on the base of receiving space; The gear post is fixed on the hook sheet and stretches into the hollow bulb of wearing piece, and there is a portion of putting forth effort that is slightly larger than the gear post lower end of the hollow bulb of wearing piece; Loop bar is hollow bulb and forms gear tooth, guide hole, and two ends of guide hole are the section of putting forth effort, wherein the lower end put forth effort Duan Youyi chamfered transition section, the expansion link sleeve is in loop bar, wearing piece and the superimposed sleeve of hook sheet are in loop bar.

Described expansion link front portion forms hinge hole, and the loop bar rear portion forms hinge hole.

The bottom of described gear tooth has arcwall face.

The beneficial effects of the utility model are: 1, its expansion link arbitrarily screens on any one gear tooth, play the function of regulating height, cleaning, when maintenance, maintenance, can open like a cork, and regulate height.Work is carried out in the place that making things convenient for the user to touch suitably needs to clean, keep in repair, maintain.When 2, using, expansion link and hinge hole on the loop bar be hinged to be needed separate on two objects that strut, and just can realize lift in height, its inconvenience is applicable to existing integration kitchen range, can also work as the auto repair strut, and the bevel angle adjustment, backrest lifting strut etc.

The specific embodiment

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in Fig. 1～5: the automatic strut of step positioning type, it is made up of expansion link 1, loop bar 2, wearing piece 4, hook sheet 3, spring 5, gear post 6, form convex tendon 11 on the expansion link 1, this convex tendon 11 matches with anterior two projectioies 12 and forms spacing space 14, and wearing piece 4 front portions 43 are fastened on 12 of two projectioies and drop in the spacing space 14; The hook sheet 3 of buckle portion 31 is housed in the receiving space 13 that matches on the expansion link 1, and spring 5 one end active forces are in the hook sheet, and the other end acts on the base of receiving space 13; Gear post 6 is fixed on the hook sheet 3 and stretches into the hollow bulb 41 of wearing piece 4, and there is a portion of putting forth effort 42 that is slightly larger than gear post 6 lower end of the hollow bulb 41 of wearing piece 4; Loop bar 2 is for hollow bulb and form gear tooth 21, guide hole 22, and two ends of guide hole 22 are the section of putting forth effort 222,223, and wherein the section of putting forth effort of lower end 222 has a chamfered transition section 221, and expansion link 1 sleeve is in loop bar 2, and wearing piece 4 and the superimposed sleeve of hook sheet are in loop bar 2.Described expansion link 1 front portion forms hinge hole 15, and loop bar 2 rear portions form hinge hole 23.The bottom of described gear tooth 21 has arcwall face 211.

Operation principle: see shown in Fig. 1,3, when expansion link 1 is moved highest order to, gear post 6 is arranged in the upper end section of putting forth effort 223 of loop bar 2, spring 5 is compressed, press expansion link 1 downwards, this moment, wearing piece 4 did not slide, portion 42 is puted forth effort in the lower end that the upper end section of putting forth effort 223 forces gear post 6 to fall into wearing piece 4, spring 5 still is compressed, pressing expansion link 1 when contracting inwards like this, gear post 6 can't contact with gear tooth 21, can be pressed onto state as shown in Figure 4 always, be reduced to the shortlyest, fall in the bottom section of putting forth effort 222.

See shown in Figure 4, when upwards spurring expansion link 1, gear post 6 is puted forth effort portion 42 from the lower end of wearing piece and is deviate from, and spring 5 elongations are run into the arc surface of gear tooth 21 and can easily be crossed, downwards during back pressure, just fallen on the gear tooth 21, thought again when rising one-level latch, continued pulling expansion link 1, recross the arc surface 211 of a higher gear tooth 21, back pressure has just been fallen again on the higher one-level gear tooth.If when wanting to push back, move maximum position as shown in Figure 3 to always, downwards back pressure repeats an epimere and moves, realize and so forth expansion link 1 arbitrarily screens on any one gear tooth 21.The section of putting forth effort of lower end 222 has a chamfered transition section 221, and this is to slip into fast in the section of putting forth effort 222 along chamfered transition section 221 for the ease of gear post 6.
