Description
Technical field
The present invention relates to a kind of on learning desk, computer desk, desk, study chair or other desk and chair, use can simple and convenient adjusting desk and the tables and chairs lowering or hoisting gear that is easy to regulate height of chair height.
Background technology
At present; Learning desk, computer desk, desk, study chair or other desk and chair are in use; Sometimes the height that need regulate height, the especially student of desk or chair according to user's sitting height changes very fast with advancing age, therefore in the process of using desk and chair, needs constantly to regulate its height; Be convenient to protect student's eyesight; In the use of desk and chair, the people of different heights has different requirement to the height of desk or chair simultaneously, all needs in use the height of desk or chair to be regulated.
At present; Desk or chair height adjusting device generally are on the double connecting plate on its interconnective two supporting legs, to be equipped with corresponding hole; Be fixed with connecting bolt in the connecting hole between two supporting legs; When regulating height; Need turn on connecting bolt, between the new connecting hole between two supporting legs, connecting bolt is installed once more by new height again, this desk or chair height adjusting device exist complex operation, difficult adjusting, effort is time-consuming, cost is high, baroque defective; To this defective, a kind of device of automatic adjusting height on market, occurred, but device is difficult to accepted by the consumer because of defectives such as its cost height, complex structures.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art and a kind of tables and chairs lowering or hoisting gear that is easy to regulate height that can regulate desk and chair height easily is provided.
The objective of the invention is to realize like this:
A kind of tables and chairs lowering or hoisting gear that is easy to regulate height; Comprise the outer supporting leg of tables and chairs, be sleeved in the outer supporting leg of tables and chairs and can be outside tables and chairs the supporting leg oscilaltion and tables and chairs that the tables and chairs supporting surface is fixedly connected in supporting leg; It is characterized in that: outside tables and chairs, all have the connecting hole of mutual correspondence in supporting leg and the tables and chairs on the supporting leg, between this corresponding each other connecting hole, be inserted with latch, the position in the tables and chairs after the supporting leg oscilaltion is regulated fixing through this latch; This latch is hingedly mounted on the outer supporting leg; This latch and outside the latch back-moving spring is installed between the supporting leg, the connecting hole that this latch head passes the outer supporting leg of tables and chairs inserts in the connecting hole of the correspondence of supporting leg in the tables and chairs, this latch back-moving spring keeps that the latch head is in and is inserted in the state in the connecting hole of the inside and outside supporting leg of tables and chairs; The face of the following contact-making surface that contacts with connecting hole of this latch head for tilting simultaneously; The connecting hole of supporting leg upwards promotes the face of this inclination in the tables and chairs when tables and chairs upwards promote, and said latch rotates around pin joint simultaneously, and the face that latch drives said inclination leaves the connecting hole of supporting leg in the tables and chairs; In tables and chairs in the supporting leg uphill process; Under the effect of latch back-moving spring, when this latch head ran into the connecting hole of supporting leg in the tables and chairs on top, this fork portion dropped in this top connecting hole; Position after supporting leg rises in the tables and chairs is retightened by this latch, accomplishes the action that improves the tables and chairs height.
The face of described inclination is meant plane, arc surface or sphere.
The outer supporting leg of described tables and chairs is fixedlyed connected with the tables and chairs supporting seat or directly is based on the ground.
Described connecting hole is a straight line and is arranged above and below outside tables and chairs in the supporting leg and tables and chairs on the supporting leg.
A kind of tables and chairs lowering or hoisting gear that is easy to regulate height; Comprise the outer supporting leg of the tables and chairs that are fixedly connected with the tables and chairs supporting surface, be sleeved on supporting leg in the tables and chairs in the outer supporting leg of tables and chairs; It is characterized in that: outside tables and chairs, all have the connecting hole of mutual correspondence in supporting leg and the tables and chairs on the supporting leg, between this corresponding each other connecting hole, be inserted with latch, the position in the tables and chairs after the supporting leg oscilaltion is regulated fixing through this latch; This latch is hingedly mounted on the outer supporting leg; This latch and outside the latch back-moving spring is installed between the supporting leg, the connecting hole that this latch head passes the outer supporting leg of tables and chairs inserts in the connecting hole of the correspondence of supporting leg in the tables and chairs, this latch back-moving spring keeps that the latch head is in and is inserted in the state in the connecting hole of the inside and outside supporting leg of tables and chairs; The face of the following contact-making surface that contacts with connecting hole of this latch head for tilting simultaneously; The connecting hole of supporting leg promotes the face of this inclination downwards in the tables and chairs when tables and chairs need promote, and said latch rotates around pin joint simultaneously, and the face that latch drives said inclination leaves the connecting hole of supporting leg in the tables and chairs; In tables and chairs in the supporting leg elongation process; Under the effect of latch back-moving spring, when this latch head ran into the connecting hole of supporting leg in the new tables and chairs, this fork portion dropped in this new connecting hole; Position in the tables and chairs after the supporting leg elongation is retightened by this latch, accomplishes the action that improves the tables and chairs height.
The present invention can regulate desk and chair height easily, has advantage simple in structure, economical and practical, that adjusting is easy, efficient is high, safe and reliable, cost is low.
