For rack rails to be attached to the base portion of door, rack rails is provided with anchor plate, and each anchor plate is provided with suitable for by being screwed into The vertical expansion slot of anchor screws engagement in the correspondence threaded hole of door.The presence of the slot is essential, this is because working as When mounted on a door, it is often necessary to gradient of the rack rails relative to horizontal axis is adjusted, to compensate ground or door itself Any defect.

It is to be noted, however, that in the long run, due to the presence of vibration and power and slot under rack rails, so rack rails tends to Its home position is lost until it makes automatic device lock.

Utility model content

The purpose of this utility model is to provide the rack rails for the aforementioned type that can overcome this disadvantage.

The purpose utilizes a kind of rack rails for door to realize.The rack rails includes rack rails main body, the rack rails main body shape At with teeth, the tooth is adapted to engage with movement of the pinion gear of electric machine part for the door, the rack rails main body be provided with from Multiple slotted plates that the side of the rack rails main body extends, and the slotted plate is provided with vertical expansion slot and connects for rack rails Screw is connect to the channel of the base portion of the door, the rack rails main body is further equipped with the locking lifting lug coplanar with the slotted plate, Manufacture has tapping screw or rivet of the circular hole for the base portion suitable for being screwed to the door in each described locking lifting lug Channel.

Further, the rack rails includes the institute for being suitable for the circular hole gapless engagement corresponding with the locking lifting lug State tapping screw or rivet.

Further, the locking lifting lug extends from two vertical edges of at least some slotted plates.

Further, single piece is made with the slotted plate in the locking lifting lug.

Further, single piece is made with the rack rails main body in the slotted plate and the locking lifting lug.

Further, the rack rails main body is made of the plastic material on metal core.

The arrangement of the utility model may insure that rack rails will not be moved from initial position.

Specific implementation mode

In the following description, the element shared with the various embodiments of rack rails according to the present utility model can be identical Reference numeral indicates.

In the accompanying drawings, one section of rack rails according to the present utility model is generally indicated with 1.Rack rails 1 is adapted for attachment to door 100 Base portion opens and closes door to allow it to slide automatically.

According to general embodiment, rack rails 1 includes rack rails main body 10, and the rack rails main body is for example by being molded on metal core Plastic material (such as, nylon) is made.

Rack rails main body 10 forms with teeth 12, which is suitable for engaging with the pinion gear 110 of electric machine part 120 for mobile door 100。

Rack rails main body 10 is provided with the multiple slotted plates 14 extended from the side of rack rails main body 10 and it is expected to tilt to allow Rack rails is pre-installed at the base portion of door by degree.

Each slotted plate 14 is equipped with vertical expansion slot 16, which is suitable for being carried at the base portion of door with being screwed into Corresponding anchor screws 18 in threaded hole made of preceding engage.

In the embodiment shown in Fig. 1 and Fig. 1 a, slotted plate 14 is downwardly projected relative to rack rails main body 10；In Fig. 2 In variant embodiment shown in Fig. 2 a, slotted plate 14 is prominent above rack rails main body 10.

Rack rails main body 10 is additionally provided with the locking lifting lug 30 coplanar with slotted plate 14.Each this locking lifting lug 30 is all provided with It is equipped with circular hole 32, for the tapping screw 34 (Fig. 3) of the base portion suitable for being screwed to door 100 or the channel of rivet 36 (Fig. 4).

Circular hole 32 is sized to couple with respective screws 34 or 36 gapless of rivet.By this method, tooth is avoided Any slight shift of the rail relative to screw or rivet.

According to one embodiment, locking lifting lug 30 extends from two vertical edge 14' of at least some slotted plates 14.

According to one embodiment, single piece is made with slotted plate 14 in locking lifting lug 30.

According to one embodiment, single piece is made with rack rails main body 10 in slotted plate 14 and locking lifting lug 30.

According to one embodiment, the slotted plate 14 with locking lifting lug 30 coplanar with each other extends on parallel plane, And the back of the plane where the rear side (that is, side towards door) in rack rails main body is set.By this method, with the surface of door The tooth 12 of the rack rails main body 10 separated can also with it is completely right with tooth more broader than those of rack rails tooth or not with tooth 12 Accurate pinion gear 110 engages.In this embodiment, have the corresponding each slotted plate 14 for locking lifting lug 30 from rack rails main body 10 rear extension 10' extends vertically.

According to one embodiment, rack rails 1 includes the metal core being made of any length and unbroken metal strip.Have The rack rails main body 10 of tooth 12, slotted plate 14 and locking lifting lug 30 can be molded on this item 11 in the form of modularization section.

Since slotted plate 14 and threaded hole being made at the base portion of door, so rack rails 1 can easily and rapidly pacify in advance On door.

Once rack rails is pre-mounted in correct position, tapping screw 34 or rivet 36 are just for for good and all locking rack rails On door.Due to the use of tapping screw 34 or rivet 36, and due to the nothing between hole 32 and tapping screw 34 or rivet 36 Gap couples, it can be ensured that rack rails will not be moved from initial position.

For the embodiment of rack rails according to the present utility model, in order to meet the needs decided as circumstances require, without departing substantially from In the case of scope of the appended claims, the other elements that those skilled in the art can utilize function equivalent are to some elements Make modification, change and replacement.The each feature for being described as belonging to a possible embodiment can be independently of described Other embodiment is realized.
