Detailed Description

The utility model provides an integral type desk chair, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following refers to the attached drawing and the embodiment of lifting the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 and 9, the present invention provides an integrated desk and chair, which comprises a support 1, a seat plate 2 and a desk plate 3; in addition, the integrated desk and chair also comprises a seat plate resetting mechanism 5 and a desk plate folding mechanism 6.

As shown in fig. 1, 2 and 3, the seat plate returning mechanism 5 includes a supporting seat 51 fixed to the front side of the supporting seat 1 by a bolt, a mounting seat 52 fixed to the bottom surface of the seat plate 2 by a bolt, a gas spring 53, and a first torsion spring 54 horizontally sleeved on the supporting seat 51. The rear end of the mounting seat 52 is hinged to the supporting seat 51. One end of the gas spring 53 is hinged to the supporting seat 51, and the other end of the gas spring 53 is hinged to the mounting seat 52. One end of the first torsion spring 54 is fixedly arranged on the supporting seat 51, and the other end of the first torsion spring 54 is fixedly arranged on the mounting seat 52.

Fig. 2 shows the structure of the seat plate 2 in the use state. At this time, the torsion spring 54 is deformed by the action force of the mounting seat 52, and the gas spring 53 is in the piston rod retraction state, and the bottom surface of the mounting seat 52 is supported by the top surface of the supporting seat 51, so that the mounting seat 52 cannot continuously swing downwards, and the user can be supported stably and reliably, and the pressure bearing capacity is strong.

Fig. 3 shows the structure of the seat plate 2 in the non-use state (folded storage). After the human body leaves, the torsion spring 54 returns to its original shape, and applies a force to the mounting seat 52 to drive the mounting seat 52 to swing upward with the seat plate 2. Meanwhile, the piston rod of the air spring 53 extends slowly, so that the swinging speed of the mounting seat 52 is stable and not urgent, the automatic resetting stability of the seat plate 2 is ensured, and people cannot be injured by mistake.

As shown in fig. 1, 9, 10, and 11, the table folding mechanism 6 includes a fixing base 62 fixed to the rear side of the support base 1 by bolts, a support rod 61 fixed to the left and right sides of the table 3, a second torsion spring 67 horizontally sleeved on the fixing base 62, a ratchet wheel 64 with one ratchet tooth, a pawl 68 located below the ratchet wheel 64, an action wheel 65 with one tooth, and a horizontally disposed fixing shaft 66.

The front end of the supporting rod 61, the ratchet wheel 64 and the action wheel 65 are coaxially and rotatably arranged at the top end of the fixed seat 62. The pawl 68 is rotatably disposed on the holder 62. The upper end of the second torsion spring 67 is abutted against the front side surface of the pawl 68, and the lower end of the second torsion spring 67 is connected with the fixed seat 62. The fixed shaft 66 is fixedly arranged on the support rod 61 and the ratchet wheel 64, so that the ratchet wheel 64 and the support rod 61 can rotate synchronously. The action wheel 65 is provided with an arc-shaped hole 651 adapted to insert a fixed shaft 66. The tooth portion 652 has a top surface higher than the ratchet teeth, as shown in fig. 12 and 13.

When the table 3 is placed horizontally, the pawl 68 engages with the teeth of the ratchet wheel 64 and the action wheel 65, as shown in fig. 11.

The utility model provides a table folding mechanism's work flow as follows:

fig. 11 shows the structure of the table in the use state. As shown in fig. 10, 11 and 15, at this time, the fixed shaft 66 contacts with the lower wall surface of the arc hole 651 of the action wheel 65, and the action portion 681 of the pawl 68 is clamped in the tooth grooves of the ratchet wheel 64 and the action wheel 65, so as to prevent the ratchet wheel 64 and the action wheel 65 from continuing to rotate clockwise, thereby ensuring that the table top can maintain a horizontal stable state and has strong pressure bearing capacity.

As shown in fig. 10 and 12, when the table 3 needs to be switched from the use state to the folding storage state, the table 3 is first turned up by a certain angle, at this time, the support rod 61 carries the ratchet wheel 64 to rotate counterclockwise, the action wheel 65 rotates counterclockwise by the same angle due to the acting force of the fixed shaft 66 positioned in the arc hole 651, the pawl 68 rotates clockwise and is separated from the ratchet wheel 64, after the pawl 68 leaves from the tooth space, the pawl 68 cannot rotate clockwise due to the obstruction of the tooth part of the action wheel 65 and the acting force of the upper end of the second torsion spring 67, and at the same time, the support rod 61 cannot rotate counterclockwise and is subjected to a large resistance due to the fact that the action wheel 65 cannot rotate counterclockwise, and the table 3 cannot be turned up.

Then, the table 3 needs to be turned down, that is, the support rod 61 rotates clockwise with the ratchet wheel 64. The fixed shaft 66 is driven by the ratchet wheel 64 to rotate clockwise, and due to the arc-shaped hole 651, the action wheel 65 still keeps a static state until the fixed shaft 66 moves to the upper wall surface of the arc-shaped hole 651, and at this moment, the tooth grooves of the ratchet wheel 64 and the tooth grooves of the action wheel 65 are dislocated, as shown in fig. 10 and 13.

The purpose of setting up the action wheel is in order to be able to withstand the pawl through the tooth portion of action wheel after the pawl leaves the tooth's socket to avoid the pawl to block into the tooth's socket once more when the ratchet rotates with the adjustment of its tooth's socket position, finally realize releasing the joint of pawl and ratchet.

Then, the table is continuously turned down to a folding and storing state (or a non-use state). In the case of clockwise rotation of the support rod 61 and the ratchet wheel 64, the operating wheel 65 is synchronously rotated by the fixed shaft 66 moving to the upper wall surface of the arc hole 651 and applying an urging force, the tooth space position of the operating wheel 65 is also changed, and the pawl 68 is rotated counterclockwise by the urging force of the second torsion spring 67 until the operating portion 681 of the pawl 68 comes into contact with the tooth back of the ratchet wheel 64 and slides, as shown in fig. 10, 14, and 15.

When the table is switched from the non-use state to the use state, the table is turned upwards, that is, the supporting rod 61 is rotated counterclockwise. During rotation, the ratchet wheel 64 rotates together with the fixed shaft 66. When the fixed shaft 66 moves to the lower wall surface of the arc-shaped hole 651, the action wheel 65 rotates together with the ratchet wheel 64 due to the acting force of the fixed shaft 66, and at the moment, the tooth socket position of the ratchet wheel 64 is overlapped with the tooth socket position of the action wheel 66; the ratchet wheel 64 and the action wheel 65 rotate counterclockwise until the action part 681 of the pawl 68 enters the tooth grooves of the ratchet wheel 64 and the action wheel 65, and then the strut is rotated clockwise, so that the pawl 68 is urged to produce a clamping action with the ratchet wheel 64 and the action wheel 65, as shown in fig. 10, 11, 14 and 15.

The second torsion spring 67 is provided to urge the pawl 68 so that the operating portion 681 can come into contact with the tooth back of the ratchet wheel 64, and to ensure that the pawl 68 is engaged in the tooth groove when the ratchet wheel 64 and the tooth groove of the operating wheel 68 are rotated together in position, as shown in fig. 10, 14, and 15.
