On touch panel, the smooth rail is arranged between two mounting plates.
Further, dovetail groove or T-slot of the oblique sliding rail between connecting plate and mounting rack.
Further, the oblique sliding rail includes slide guide column and slider guide, and the slider guide and slide guide column are installed respectively
On connecting plate and mounting rack.
Further, the smooth rail includes slide guide bar and guide sliding base, and the guide sliding base is separately mounted to two installations
On frame.
Further, the T-type guide rail of installation conductor rail and contact plate is equipped on the mounting plate, in the contact
Plate is equipped with the T-type guide groove cooperated with T-type guide rail, and the fastening of fixed contact plate and conductor rail is additionally provided on the mounting plate
Bolt.
The advantages of innovation and creation and good effect:
1, expansion element carries out modularized design, except mounting rack installation conductor rail position in two sides is different according to conductor rail form
It adjusts outer, remaining part is generally applicable.
2, by the cooperation between connecting plate and mounting rack, guarantee the initial slippage power of product;
3, it is designed by structure, two inclined surface and V-type face remain contact, guarantee expansion element current collection when flexible
Boots are continuous always with contact surface;
4, by the design of mis-cut angle, guarantee in telescopic process, connecting plate without departing from conductor rail limit, simultaneously
Guarantee collector shoe and the virtual contact width by stream interface.

Specific embodiment
It includes mounting rack 1 and connecting plate 3 that the present invention, which provides a kind of conductor rail power supply system modular expansion element, wherein pacifying
Shelve 1 and be symmetrical arranged a pair, connecting plate 3 is slidably arranged between mounting rack 1, and the collector shoe due to train and mounting rack 1 and
Connecting plate 3 is required to contact, therefore the flush of the connecting plate 3 and the mounting plate 1-1 of two sides and collector shoe contact side.Two
Mounting rack 1 is separately fixed on two adjacent rail-engagings, flexible busbar 2 is connected between two mounting racks 1 by current lead-through,
Flexibility busbar 2 can carry out deformation adjustment according to the distance between two mounting racks 1 when expanding with heat and contract with cold.It is equipped on mounting rack 1
Inclined surface 1-21, the inclined surface 1-21 on each mounting rack 1 are located at two mounting racks, the 1 V-shaped arrangement in adjacent side, on connecting plate 3
Inclined surface 1-21 equipped with V-type face 3-1 and two sides is mutually matched, V-type face 3-1 be placed between two inclined surface 1-21 and mutually
Contact, when spacing changes between two mounting racks 1, V-type face 3-1 and inclined surface 1-21 is opposite slides, and connecting plate 3 is
There is small range mobile in vertical direction, remains pass through V-type face 3-1 and inclination with two sides mounting rack 1 in the horizontal direction
Face 1-21 is in close contact, so that it is uninterrupted among good continuity to have the expansion element in the case where expanding with heat and contract with cold,
Safety guarantee is provided for train operation.
On the basis of above, the present invention in order to make structure more firm in actual use, done on specific structure into
The optimization design of one step: as shown in Figure 1: include two symmetrically arranged mounting racks 1, connected between two mounting racks 1 flexible
Busbar 2, connecting plate 3, which is arranged between two mounting racks 1, contacts opposite sliding with inclined surface 1-21 by V-type face 3-1, in order to protect
It slides relatively stable between card connecting plate 3 and mounting rack 1, oblique sliding rail is respectively set between the mounting rack 1 of connecting plate 3 and two sides
4, the oblique sliding rail 4 is parallel with inclined surface 1-21, and oblique sliding rail 4 is the structure of dovetail groove or T-slot in the embodiment, and existing guiding is made
With connecting plate 3 and mounting rack 1 can be prevented to be detached from again, specifically dovetail groove or T-slot can be set up directly on connecting plate 3 and peace when setting
Shelve 1.
As shown in Figure 2 since connecting plate 3 and 1 contact surface of mounting rack are smaller, be arranged embodiment 1 in 4 structure of oblique sliding rail compared with
For difficulty, therefore slide guide column 4-1 and the oblique sliding rail 4 of structure setting to sliding block are used, as shown in Figure 5 by slider guide 4-2 and slide guide column
4-1 is separately mounted to realize guiding on connecting plate 3 and mounting rack 1, relative to the more convenient implementation of the structure of embodiment 1.
In the case where being provided with oblique sliding rail 4, as shown in Figure 3 in order to further increase the stability of expansion element, due to
Two mounting racks 1 have displacement in conductor rail extending direction, to be also provided with smooth rail 5 between two mounting racks 1 to two
Mounting rack 1 carries out the guiding in horizontal displacement direction, and the smooth 5 packet guide sliding base 5-2 of rail and slide guide bar 5-1 is relatively only as shown in Figure 6
Vertical guide sliding base 5-2 is separately mounted to realize guiding to the mounting rack 1 of two sides on two mounting racks 1.Flexible mother under this structure
It arranges 2 medium positions and is capable of fixing on smooth rail 5 the M type that formed, the height that can be effectively reduced flexible busbar in this way avoids interference with.
Mounting rack 1 is made of mounting plate 1-1 and contact plate 1-2 in the above structure as shown in Figure 4, and flexible busbar 2 connects
It connects on mounting plate 1-1, contact plate 1-2 is fixed on mounting plate 1-1, and inclined surface 1-21 is then arranged on contact plate 1-2, tiltedly sliding
Rail 4 is arranged between contact plate 1-2 and connecting plate 3, and smooth rail 5 is arranged between mounting plate 1-1.Mounting rack 1 due to contact
T-type guide rail 1-11 is arranged for installing conductor rail in rail connection on mounting plate 1-1, and T-type guide rail 1-11 can be according to contact
Rail form difference is replaced, and rest part is generally applicable to realize modularized design in addition to T-type guide rail 1-11, is simultaneously
Facilitate installation contact plate 1-2, setting and the matched T-type guide groove 1-22 of T-type guide rail 1-11 on contact plate 1-2, in mounting plate 1-1
On be additionally provided with the fastening bolt 6 of fixed contact plate 1-2 and conductor rail.After conductor rail is installed on mounting plate 1-1, conductor rail,
The one side that contact plate 1-2 and connecting plate 3 are contacted with collector shoe is concordant, guarantees that the contact of collector shoe well provides good conducting wire
Property.
