At first see also Fig. 1 to shown in Figure 6, the slipping mechanism of the utility model pulling type dining table, its structure includes:

A frame body 10 includes two forward and backward horizontal stripes 11; Two slide track components 20 are that to be consolidated in this two forward and backward horizontal stripe 11 with two ends respectively distolateral relatively, and its detailed structure repeats after holding, the combination of this two forward and backward horizontal stripe 11 of mat and two left and right sides slide track components 20 and obtain quadra; Four pillars 30 are to be arranged at this square box quadripolar corners respectively, and each is fixed with top and this horizontal stripe 11 and adjacent slide track component 20.

One internal frame 40 is to be arranged in the quadra of this frame body 10, includes the interior horizontal stripe 41 of two parallel these horizontal stripes 11; A positioning rod 42 is to link with the interior horizontal stripe 41 relative inner faces of two ends and this; Horizontal stripe 41 inner faces then offer an arc relatively to guide channel 411 in each in this.

One exposes table 50, is to form with two table 50A, 50B, for being arranged on these frame body 10 quadras, just can cover in this quadra.

One hides table 60, be to be arranged in this internal frame 40, it is can lift folded reduced size table 60A by two, 60B forms, this two table 60A, 60B is for the hinge being the pivot of living, length is provided with a guide rod 61 in this table 60B bottom side, this table 60A is also protruded in these guide rod 61 two ends, the distolateral suitable length of 60B, just can plug together in the guide channel 411 of horizontal stripe 41 in this, by this, when the guide rod 61 of this table 60 is displaced to this guide channel 411 upper extreme points, then this table 60A is able to this hinge and carries out for the pivot center swing of living and cover this internal frame 40 1 half spaces, simultaneously, this another table 60B must cover in addition half space of this internal frame, and hiding table 60 side direction after the expansion are subjected to this to expose table 50 to insert and put, put so can firmly open up.

This each slide track component 20 is to include the microscler moulding 21 of similar C-shaped without exception, and the top of this moulding 21, root edge are difference relief one curved surfaces, and make these moulding 21 top root edges form a spill room 22; Two pulleys 23 are to be positioned this two sides, microscler moulding 21 opposite end with pivot respectively, think the original place rotation; Two slide plates 24 are to be arranged at this microscler moulding 21 openings two sides respectively, generally be L shaped, and the shorter face of this each slide plate 24 are contour with the curved surface peak of this moulding 21; Eight guide wheels 25, be to be divided into two groups, each organizes guide wheel is the upper and lower side that is positioned this each slide plate 24 with numbers such as pivots respectively, and this each guide wheel 25 is can be placed in the spill room 22 of this moulding 21, this each guide wheel 25 of mat is subject in the track of this spill room 22 and makes this two slide plate 24 can keep stable craspedodrome ability, when producing utilization on the practice, these guide wheels 25 must be made for hard plastic wheel or bearing ... element Deng the flexible turning power of tool; This slide plate 24A's is to be provided with a towing unit 70 away from these pulley 23 lower sides, this towing unit 70 is to include one first keeper, it is the hook sheet 71 of making the tail end warpage, be to close on inner downside from this slide plate 24A to bend shaping in the punching out mode, its central authorities have a saturating empty outside positioning embeded groove 72, this caulking groove 72 generally is " Ω " shape, one second keeper 74, be to be arranged at this hook sheet 71 the place aheads, it generally is the  font, two parallel-segment of this second keeper 74 are provided with four tenons 741 outward, the linkage section of this second keeper 74 then offers a short slot 742, in this first slide plate 24A relatively these second keeper, 74 tenons, 741 positions then punching out perforation 26 is arranged, these perforation 26 are can place for the tenon 741 of this second keeper 74 and make this second keeper 74 be fixed in this first slide plate 24A; One rope 80, be to be cross-placed in the positioning embeded groove 72 of this hook sheet 71 in conjunction with a block 81 with an end, utilize the block of this block 81, these rope 80 1 ends must be positioned on this hook sheet 71, this rope 80 end is in addition then walked around this each slide plate 24A respectively, the pulley 23A of 24B, 23B and the  that is linked in second keeper 74 of this first slide plate 24A describes in the chamber, being positioned at this second slide plate 24B upper end one in this rope 80 sentences a fixture 29 and fixes this rope 80 and be incorporated on this second slide plate 24B, this rope 80 is held in addition also in conjunction with a block 82, how long the more aforementioned block 81 in the outer end of this block 82 establishes the rank portion 821 in big footpath, in this  shape keeper 74, more be provided with a compression spring 85, this compression spring 85 just can an end against the rank portion 821 of this block 82, end is resisted against the linkage section internal face of this keeper 74 in addition, makes this rope 80 have pulling force compensation adjustment function by this.

Via above-mentioned, two slide plate 24A, the 24B of this each slide track component 20 must be because of the user's drawing or the action of slippaging, and the microscler relatively moulding 21 in the towing unit 70 of utilization itself is for separating or the closing action.

As Fig. 7, Fig. 8, shown in Figure 9, it is the action situation of the utility model first embodiment, when this exposes two table 50A of table 50, after 50B covers on the slide plate 24 that is locked in this two slide track component 20, if the user will expand the usable floor area of dining table, then only need this table 50A of pulling or 50B outward, then this slide plate 24A or 24B utilize rope 80 synchronous these towing unit 70 relative desk center lines that drive to be separating action, and by each guide wheel 25 straight line slippage in the alcove room 22 of this moulding 21, can reach the table expansion operation in fast and stable ground, afterwards, the guide rod 61 of these hiding table 60 utilizations itself is these guide channel 411 upper extreme points of pan position up, should hide table 60 and turn to lift, can carry out covering internal frame 40 spaces, so far, this expose table 50 and should hide table 60 mutually and lean on, can finish the operation of desktop expansion; Otherwise, in the time will receiving the stand area, it is folding only to need to hide table 60 reverse swings, and utilize guide rod 61 down to be displaced to this guide channel 411 lower extreme points, end then is positioned on the backstay 42 in addition, to expose table again toward interior passing, then this two table 50A, 50B covers this concealed table 60 and merging is drawn close to finish and folded operation.

According to the above, the slide track component that the utility model utilizes new-type towing unit to be constituted, it really can make, and more balance is certain in the table operation, and use is upward convenient smooth and easy, moreover its employed part is obtained easy to manufacture, so can reduce production costs.
