Description

Sliding door

Technical field

The utility model relates to a kind of sliding door, more particularly, relates to the sliding door in a kind of subway shield door system.

Background technology

Aluminium extruded sections is employed widely owing to have numerous advantages such as easy processing, light weight and makes decorating and renovating material.In the subway half-height safety door system, the doorframe of sliding door is to adopt aluminium alloy extrusions to make to satisfy the different decorated style requirements at each station basically at present.Traditional aluminium alloys slip every body is that doorframe all is to be joined end to end by upper and lower crossbeam and left and right perpendicular material to form a tetragonal doorframe.Being the bonding strength of reinforcement doorframe, is that four jiaos of places use angle sign indicating number part of doorframe is reinforced in crossbeam and perpendicular material connection.Can only prevent that crossbeam and perpendicular material are separated but use angle sign indicating number part to reinforce at present, doorframe can not disintegrated, the effect that the intensity of strengthening doorframe is promptly improved the anti-twist deformability of doorframe is very little, therefore, poor, the yielding twisted defective of the anti-twist deformation performance of sliding door ubiquity in present subway half-height safety door system, particularly in use run under the situation of external impacts, the distortion meeting of generation can't normally use sliding door because of invading vehicle gauge.

The utility model content

The technical problems to be solved in the utility model is, at poor, the yielding twisted defective of doorframe torsional resistance of existing sliding door, and provides a kind of doorframe torsional resistance good, not yielding twisted sliding door.

The technical scheme that its technical problem that solves the utility model adopts is: propose a kind of sliding door, comprise doorframe, described doorframe comprises crossbeam, perpendicular material, the group hornblock, described crossbeam and perpendicular angled end-face vertical be connected of material by cooperatively interacting, described crossbeam has axial crossbeam endoporus, perpendicular material has axial perpendicular material endoporus, described crossbeam endoporus and perpendicular vertical perforation the in angled end-face place of expecting that endoporus matches with perpendicular material at crossbeam, described group of hornblock is to be made of orthogonal first Plug Division and second Plug Division, the described first Plug Division sleeve also closely cooperates with it in described crossbeam endoporus, and the described second Plug Division sleeve also closely cooperates with it in described perpendicular material endoporus.

In sliding door described in the utility model, the position that plugs together in described crossbeam and first Plug Division is provided with several first trip bolts that crossbeam and first Plug Division are fastenedly connected, and the position that plugs together in described perpendicular material and second Plug Division is provided with several will erect second trip bolt that material and second Plug Division are fastenedly connected.

In sliding door described in the utility model, described first trip bolt, second trip bolt are separately positioned on the lateral wall of described crossbeam, perpendicular material.

In sliding door described in the utility model, the inclination angle of the angled end-face that matches on described crossbeam and the perpendicular material is 45 degree.

In sliding door described in the utility model, described first Plug Division is identical with the structure of second Plug Division.

In sliding door described in the utility model, the shape of cross section of described first Plug Division and second Plug Division is square.

In sliding door described in the utility model, described group of hornblock is the aluminium alloy casting member.

Implement the sliding door in the utility model, have following beneficial effect: since two orthogonal first Plug Divisions of group hornblock and second Plug Division respectively sleeve in crossbeam endoporus and perpendicular material endoporus, closely cooperate with endoporus formation, this not only can improve crossbeam and perpendicular bonding strength of expecting, simultaneously also can be when door be subjected to external impact force, the angle chunk can bear enough big moment of torsion, prevent the anti-twist distortion of doorframe, this group of hornblock easy processing and manufacturing simple in structure simultaneously, when being used to organize frame, can play the guiding role, make things convenient for crossbeam and the installation that cooperates of erecting material.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the structural representation of the doorframe part of the utility model sliding door;

Fig. 2 be Fig. 1 A-A to structural representation;

Fig. 3 be Fig. 1 B-B to structural representation.

The specific embodiment

Fig. 1 to Fig. 3 shows a more excellent embodiment of the present utility model.

The doorframe of sliding door mainly be by two be positioned at the crossbeam of upper-lower position, two perpendicular material that are positioned at position, the left and right sides constitute through joining end to end, and are tetragonal mount structure.As shown in Figure 1, crossbeam 10 is connected on the angle of doorframe with perpendicular material 20, and crossbeam 10 is angled end-faces with the end face of perpendicular material 20, and promptly their fitting faces 40 of cooperatively interacting are inclined-planes, and its angle of slope is 45 degree.In crossbeam 10 and perpendicular material 20 ends that are connected, be provided with a group hornblock 30, group hornblock 30 is to be made of orthogonal first Plug Division 31 and second Plug Division 32, and first Plug Division, 31 sleeves are in crossbeam endoporus 11, and second Plug Division, 32 sleeves are in perpendicular material endoporus 22.As shown in Figure 2, the transverse profile of first Plug Division 31 is square, first Plug Division, 31 sleeves are at crossbeam endoporus 11, the wall of its four faces and crossbeam endoporus 11 endoporus is fitted, formation closely cooperates, on the lateral wall 12 of crossbeam 10 by first trip bolt 33 with first Plug Division 31 and crossbeam 10 lockings, prevent that first Plug Division 31 from withdrawing from from crossbeam endoporus 11.Second Plug Division 32 is identical with the syndeton of crossbeam 10 with first Plug Division 31 with the syndeton of perpendicular material 20.As shown in Figure 3, second Plug Division, 32 sleeves are in perpendicular material endoporus 21, fit with the wall of perpendicular material endoporus 21 in four sides of second Plug Division 32, formation closely cooperates, on the lateral wall 22 of perpendicular material 20 by second trip bolt 34 with second Plug Division 32 and perpendicular material 20 lockings, prevent that second Plug Division 32 from withdrawing from from perpendicular material endoporus 22.In the present embodiment, group hornblock 30 is aluminium alloy casting members, the structure of its first Plug Division 31 and second Plug Division 32, measure-alike, and the size on the cross section of perpendicular material endoporus 21 and crossbeam endoporus 11 is also identical.

During 30 groups of frames of utilization group hornblock in the present embodiment, first Plug Division 31 and second Plug Division 32 of group hornblock 30 are inserted into respectively in perpendicular material endoporus 21 and the crossbeam endoporus 11 fully, perpendicular material 20 is cooperated with the angled end-face of crossbeam 20, on the lateral wall of perpendicular material 20 and crossbeam 10, lock respectively again,

ornamental strip

51,52 is installed respectively in the outside is again got final product with screw.In the present embodiment, because first Plug Division 31 of group hornblock 30, the lateral surface of second Plug Division 32 are fitted with perpendicular material endoporus 21, crossbeam endoporus 11 walls respectively, during frame, group hornblock 30 can play guide effect in group, can easily finish the cooperating of angled end-face of perpendicular material 20 and crossbeam 10.Organize in the use after frame is finished the formation doorframe, because the aluminium alloys group hornblock 30 that forms by casting can bear enough big moment of torsion, can improve doorframe torsional deformation ability, even in use, when door is subjected to external impacts, also can not be distorted and be out of shape and the normal use of influence.
