Specific embodiment

Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：

Embodiment：Referring to shown in Fig. 1-5：

One kind plays lock fixed pattern operating desk, referring to shown in Fig. 1-3, including table top 1 and is arranged at the foot stool 2 at the two ends of table top 1, The foot stool 2 includes two columns 21 and the crosspiece 22 being connected between two columns 21, two columns 21 of the foot stool 2 and the side of table top 1 Portion is stacked and is hinged by pivot 3.

Referring to shown in Fig. 1-3, the sidepiece of the table top 1 is installed with a reinforced sheet 11 with the place of being stacked of column 21；The column 21 Strengthen liner 212 including a rod member 211 and, the reinforcement liner 212 is fixedly arranged on column 211 and platform corresponding to reinforced sheet 11 Being stacked between place, and reinforcement liner 212 and rod member 211 for the sidepiece of face 1 is formed with a cavity.

Specifically as shown in figure 1, it is an opening towards outside U-shaped section body to strengthen liner 212, and the section of rod member 211 is also U Shape, but its opening is inner side towards table top, strengthens liner 212 and opening is mutually fastened and is fixedly connected with opening with rod member 211, A cavity is just formed between the two.

Specifically as shown in figure 1, being hinged between the column 21 and the sidepiece of table top 1 of the foot stool 2, is specifically worn with pivot 3 Cross reinforced sheet 11 and strengthen the composition of liner 212 and be hinged, and the head of pivot 3 is also hidden in the cavity.

Referring to shown in Fig. 1 and Fig. 4, a bullet pin mechanism 4 is provided with least cavity of a column 21 of foot stool 2, the bullet pin Mechanism 4 includes lock pin 41 and spring 42, and the lock pin 41 is slideably positioned in the cavity inside along the length direction of column 21, Stretched towards the side of reinforced sheet 11 on lock pin 41 and be provided with pin rod end 411, the pin rod end 411 is specifically through the elongated hole strengthened on liner 212 Stretched out to reinforced sheet 11.

Referring to the pin rod end 411 for corresponding to lock pin in the folding process of foot stool 2 shown in Fig. 1 and Fig. 4, on the reinforced sheet 11 Movement locus is provided with escape groove 5, and the position of pin rod end 411 of lock pin is provided with one when corresponding to 2 holding state of foot stool in the escape groove 5 Lock fit position 51.Specifically as shown in FIG., escape groove 5 is half groove of a lower open mouth, and lock fit position 51 is the end of escape groove 5 Recessed formation upward.

Referring to shown in Fig. 1 and Fig. 4, the spring 42 is acted on lock pin 41, makes the pin of the lock pin under the holding state of foot stool 2 Rod end 411 can snap in lock fit position 51 and lock, and spring 42 drives lock pin 41 to move upwards, even if the pin rod end of lock pin 41 411 offset cooperation with the upper edge of escape groove 5 always, and when foot stool 2 goes to holding state, the pin rod end 411 of lock pin 41 falls Enter and pinned in lock fit position 51.

Referring to shown in Fig. 1 and Fig. 4, the guiding particularly for lock pin 41 sets and is：One is installed with the reinforcement liner 212 Pilot hole, the lock are offered on upper support chip 2121 and lower support chip 2122, upper support chip 2121 and lower support chip 2122 The upper end of pin 41 is stretched and is provided with a guide post, and its lower end is also stretched and is provided with a guide post, upper end guide post and the upper support chip of lock pin 41 2121 pilot hole is oriented to and coordinates, and the lower end guide post of lock pin 41 is oriented to the pilot hole of lower support chip 2122 and coordinates.

Referring to shown in Fig. 1 and Fig. 4, the spring 42 is stage clip, and it is sheathed on the lower end guide post of lock pin 41, spring 42 Lower end press on lower support chip 2122, upper end is pressed on lock pin 41.

Referring to shown in Fig. 1-Fig. 3, lock pin 41 is provided with one and stirs operating portion 412 towards column is overhanging, on operating portion 412 is stirred It is equipped with one and pushes away torsion 6, with convenient to operate.

It is shown in Figure 4 when the present embodiment is used, due to the effect of spring 42, the pin rod end 411 of lock pin 41 always with keep away The upper edge of groove 5 is allowed to offset cooperation, as long as the pin rod end 411 of lock pin 41 can be from when foot stool 2 is gone to holding state by user Dynamic falling into lock fit position 51 is pinned.When foot stool 2 is folded, it is necessary to user pushes down on push button 6 and rotates foot stool 2, push button 6 overcomes the active force of spring 42 to move downward with pendulum lock pin 41, the pin rod end 411 of lock pin 41 is deviate from lock fit Position 51 unlocks, and continues upset foot stool 2 i.e. foldable.

The present embodiment simple structure, low manufacture cost；Play lock fit position in lock pin and the escape groove in pin mechanism Coordinate more reliable, can guarantee that and reliably lock；And bullet pin mechanism is hidden in the column internal cavities of foot stool, is not exposed, profile It is neat and artistic.

In the present embodiment, there can also be following change：

1st, shown in Figure 5, escape groove 5 is a complete elongated slot, lock fit position 51 be the end of escape groove 5 down The recessed formation in side, spring 42 drives lock pin 41 to move downward, make the pin rod end 411 of lock pin 41 always with the lower side of escape groove 5 Edge offsets cooperation.

2nd, reinforced sheet 11 is not provided with, escape groove 5 is directly opened on the sidepiece of table top 1；

3rd, play pin mechanism 4 and be directly arranged in the both sides of the outside of column 21 or column 21 on the length direction of table top 1, this is equal It is feasible.

4th, spring 42 removes stage clip, or extension spring or spring leaf.

Above-described embodiment only to illustrate technology design of the present utility model and feature, technique is familiar with its object is to allow Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
