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：

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

Referring to shown in Fig. 1-3, described table top 1 sidepiece and column 21 place of being stacked are installed with a reinforced sheet 11；Described column 21 Including a rod member 211 and a reinforcement liner 212, described reinforcement liner 212 is fixedly arranged on column 211 and platform corresponding to reinforced sheet 11 Face 1 sidepiece be stacked place, and strengthen being formed with a cavity between liner 212 and rod member 211.

Specifically as shown in figure 1, strengthening liner 212 for an opening towards outside U-shaped section body, and the section of rod member 211 is also U Shape, but its opening is inner side towards table top, strengthens liner 212 and with opening, opening is mutually fastened with rod member 211 and be fixedly connected, Just form a cavity between the two.

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

Referring to shown in Fig. 1 and Fig. 4, in the cavity of at least one root post 21 of foot rest 2, it is provided with a bullet pin mechanism 4, this bullet Latch mechanism 4 includes lock pin 41 and spring 42, and described lock pin 41 is slideably positioned in described cavity along the length direction of column 21 Portion, lock pin 41 is stretched towards reinforced sheet 11 side and is provided with pin rod end 411, and this pin rod end 411 specifically passes through the length strengthened on liner 212 Hole is stretched out to reinforced sheet 11.

Referring to shown in Fig. 1 and Fig. 4, described reinforced sheet 11 corresponds to the pin rod end 411 of lock pin in foot rest 2 folding process Movement locus is provided with escape groove 5, and when this escape groove 5 corresponds to foot rest 2 holding state, pin rod end 411 position of lock pin is provided with one 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 escape groove 5 end Recessed formation upward.

Referring to shown in Fig. 1 and Fig. 4, described spring 42 acts on lock pin 41, makes the pin of lock pin under foot rest 2 holding state 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 are offseted with the upper edge of escape groove 5 cooperation always, and when foot rest 2 goes to holding state, the pin rod end 411 of lock pin 41 falls Enter in lock fit position 51 and pin.

Referring to shown in Fig. 1 and Fig. 4, the guiding setting particularly for lock pin 41 is：It is installed with one on described reinforcement liner 212 All pilot hole is offered, described lock 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, the upper end guide post of lock pin 41 and upper support chip 2121 pilot hole guiding cooperation, the lower end guide post of lock pin 41 is coordinated with the pilot hole guiding of lower support chip 2122.

Referring to shown in Fig. 1 and Fig. 4, described 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 presses on lock pin 41.Described spring 42 can also adopt extension spring or bullet Reed.

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 stirring operating portion 412 It is equipped with one and push away torsion 6, with convenient to operate.

When the present embodiment uses, shown in Figure 4, due to the effect of spring 42, the pin rod end 411 of lock pin 41 always with keep away Allow the upper edge of groove 5 to offset cooperation, if user foot rest 2 is gone to the pin rod end 411 of lock pin 41 during holding state can be from Dynamic falling in lock fit position 51 is pinned.When folding foot rest 2, user is needed to push down on push button 6 and rotate foot rest 2, the active force that push button 6 overcomes spring 42 with pendulum lock pin 41 moves downward, and makes the pin rod end 411 of lock pin 41 deviate from lock fit Position 51 unblock, it is foldable for continuing upset foot rest 2.

The present embodiment structure is simple, low manufacture cost；Play lock fit position in lock pin and the escape groove in pin mechanism Cooperation is more reliable, can guarantee that and reliably locks；And bullet pin mechanism is hidden in the column internal cavities of foot rest, do not expose, profile Neat and artistic.

In the present embodiment, can also there is following change：Shown in Figure 5, escape groove 5 is a complete elongated slot, described lock Surely cooperation position 51 is the recessed formation downward of escape groove 5 end, and spring 42 drives lock pin 41 to move downward, and makes the pin rod of lock pin 41 End 411 is offseted with the lower edge of escape groove 5 cooperation always.

Above-described embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with technique 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. All equivalence changes made according to the utility model Spirit Essence or modification, all should cover protection domain of the present utility model it Interior.
