The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of desk, mainly is made up of table leg 1, table tripe 2 and desktop 3.Table leg 1 adopts height-adjustable bolt fixed mode to be connected with table tripe 2, and desktop 3 is connected through angle regulator 4 with table tripe 2.
Fig. 3 shows the composition structure on angle regulator 4 tops.Wherein, angle regulator 4 comprises devices such as crank 5, frame 6, ratchet 7, switch block 8 and spring 9.Wherein, Crank 5 is for being arranged on a plurality of equal in length between desktop and the table tripe and the crank that is parallel to each other; And two ends respectively pivotal connection in table tripe 2 and desktop 3, in the present embodiment, the crank 5 that preferably two equal in length is set respectively and is parallel to each other at the lateral surface of table tripe 2.The bottom of crank 5 is pivotally connected to respectively on the tripe 2, and pivotal connection is in frame 6 respectively on the top of crank 5, and frame 6 is fixed on the below of desktop 3.
Referring to Fig. 4, the top of at least one crank 5 forms ratchet 10, and the circle centre position pivotal connection of ratchet 10 is in frame 6.Ratchet 7 is positioned at the side of ratchet 10; Ratchet 7 middle parts also pivotal connection on frame 6; One end of ratchet 7 has the tooth engaged 12 that is meshed with the ratchet 11 of ratchet 10, the other end pivotal connection switch block 8 of ratchet 7, and switch block 8 tops have projection and step; Spring 9 upper ends are fixed on desktop 3 belows, and spring 9 lower ends are connected on the step at switch block 8 tops.The ratchet 11 of ratchet 10 and the tooth engaged 12 of ratchet 7 are formed in the self-locking device on the desktop closing direction; Preferably open the ratchet 11 of direction and the mating surface of tooth engaged 12 has inclined-plane or the paraboloid structure that can push open each other, and have the planar structure of mutual locking towards the ratchet 11 of desktop closing direction and the mating surface of tooth engaged 12 towards desktop.
According to Fig. 5, table leg 1 can also adopt the separate type connected mode with table tripe 2, and wherein table tripe bottom and table leg top are respectively equipped with the screw that several highly do not wait, and connect through bolt.
Below according to Fig. 6, and combine the structure of Fig. 1-5, specify the course of work of the utility model.
At first; When desktop when closure state is opened; Pivotal connection relatively rotates with respect to table tripe 2 in the bottom of a plurality of parallel crank 5 of table tripe 2, drive the desktop 3 that is connected with crank 5 tops through frame 6 and upwards rotate, the while owing to crank 5 tops also with respect to frame 6 pivoted; The desktop 3 that has just guaranteed frame 6 tops remains horizontal direction in opening procedure, open desktop under the situation that article are kept intact on the table.
Secondly; Because the top of at least one crank 5 forms ratchet 10; Cooperatively interact with the ratchet 7 of side, and the mating surface of ratchet 11 and the tooth engaged 12 of ratchet 7 of opening the ratchet 10 of direction towards desktop has inclined-plane or paraboloid structure, therefore in opening the process of desktop; The ratchet 11 of ratchet 10 is constantly pushed the tooth engaged 12 of ratchet 7 open, promptly open unrestricted.After being turned to certain angle; The user need rise out hand when getting the article in the tripe; Owing to have the planar structure of mutual locking towards the ratchet 11 of desktop closing direction and the mating surface of tooth engaged 12; Make ratchet 10 and ratchet 7 form self-lockings, thereby desktop is fixed on this desired position, guaranteed the stability of desktop and easy to use.
Then, when needs closed desktop, the user can upwards push the switch block 8 that ratchet 7 right-hand members connect; Because switch block 8 top butts have spring 9; Therefore switch block can move up under the effect of pressing force within the specific limits, thereby drives ratchet 7 with respect to the pivot point on the frame 6, breaks away from engagements until the engaging tooth 12 of ratchet 7 and the ratchet 11 of ratchet 10; Therefore crank can rotate towards the desktop closing direction, thereby desktop is successfully closed.
At last, consider that user's height is different, table leg 1 can also adopt the separate type connected mode with table tripe 2, and wherein table tripe bottom and table leg top are respectively equipped with the screw that several highly do not wait, and connect through bolt.Like this, just can regulate the height of a tripe quickly and easily.
Frame, ratchet and pawl preferably adopt 45 steels to make and form, and wherein ratchet, ratchet desired strength, hardness and wearability are higher, so adopt Technology for Heating Processing, improve its performance, increase its service life.
In addition, the utility model is not only limited to the structure of the foregoing description, in the scope of the purport that does not change the utility model, can carry out various distortion.For example, the desk of the utility model can be single desk, also can be the desk with a plurality of desktops of performing fighting out.Crank can be linear pattern or shaped form; Perhaps the bottom of crank can pivot be fixed on the outside or the inboard or the bottom of a tripe.And the utility model has carried out fully record through the embodiment with reference to accompanying drawing, but clearly, concerning those skilled in the art of common knowledge with this area, also can carry out various changes and distortion.Therefore, such change and distortion should be interpreted as scope of the present invention and be included in the scope of the utility model.
