The lock groove stem is provided with a fold porch a and a fold porch 3 which are rolled toward the inner part of the groove stem, and the movable sheathed stem 4 is provided with a convex part 5 which can inserted the lock groove stem between the fold porch 2 and the fold porch 3. The utility model has the advantage of novel structure, and can add anti-picking performance of a sliding door.

Description

The sealed structure of the movable door pillar of pull gate

The utility model belongs to door and window, and the door and window of especially operating a switch is made the field.

The sealed structure of the movable door pillar of present pull gate, generally all adopt form shown in Figure 1, when sealed, pulling activity sleeve column 11 makes it to insert in the locked groove post 12, for avoiding prizing sealed back burglar the side plate 13,14 of locked groove post, movable sleeve column is provided with pick-proof convex edge 15,16.Facts have proved that this class formation still can not satisfy the pick-proof requirement well, the single-wall structure of locked groove post is the pick-proof weak point particularly.

Above shortcoming in view of prior art, the purpose of this utility model is the sealed structure of movable door pillar of the more good pull gate of a kind of pick-proof performance of design, make it to overcome the above shortcoming of prior art, under cost of production increase situation seldom, make the pick-proof performance of pull gate obtain bigger raising.

The purpose of this utility model is to realize by following structure.

Reach the sealed structure of forming with the movable sleeve column that the locked groove post plugs together mutually of the movable door pillar of pull gate by the locked groove post, the locked groove post has two convolution edges by turnup in the post groove; Has the protuberance that can insert between the locked groove post two convolutions edge on the movable sleeve column.

After having adopted structure as above, after the protuberance of movable sleeve column inserted in the locked groove post, two convolutions of movable sleeve column and locked groove post were along fitting, and two convolutions of locked groove post are along the weak structure that has changed original solid wall, under cost increase situation seldom, the pick-proof performance of sealed structure is improved greatly.

Description of drawings is as follows.

Fig. 1 is the structure chart of the sealed structure of prior art pull gate.

Fig. 2 is the constructional drawing of the sealed structure of the utility model.

Fig. 3 is the transverse sectional view of the utility model another program.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

In Fig. 2, can see, the sealed structure of movable door pillar of the utility model pull gate, by locked groove post 1 and form with the movable sleeve column 4 that the locked groove post plugs together mutually, when practical set was used, movable sleeve column linked to each other with the fence of operating a switch.Locked groove post 1 has the convolution of turnup in the post groove along 2,3, has the protuberance 5 of insertion (along the direction of arrow) locked groove post convolution between 2 and 3 on the movable sleeve column 4.

Generally speaking, convolution can be made the rectangle convolution along 2,3, but does not also get rid of other convolution form, and as shown in Figure 3, convolution can be constant slope along 2,3; Movable sleeve column close fashionable and convolution along 2,3 fit that position 6,7 also has and convolution along corresponding gradient.

Claims (2)

1, the sealed structure of the movable door pillar of pull gate by the locked groove post and form with the movable sleeve column that the locked groove post plugs together mutually, is characterized in that locked groove post (1) has the convolution edge (2,3) of turnup in the post groove; Have on the movable sleeve column (4) and can insert locked groove post convolution along the protuberance (5) between (2) and (3).

2, the sealed structure of the movable door pillar of pull gate according to claim 1, it is characterized in that, described convolution can be constant slope along (2,3), and movable sleeve column is fashionable in the pass also to have and the corresponding gradient in convolution edge (2,3) along (2, the 3) position that fits (6,7) with convolution.
