Fig. 2 is the vertical view of the simple travel switch of assembly of the utility model;
Fig. 3 is the partial enlarged view at I in Fig. 2;
Fig. 4 is partial enlarged view when assembling simple travel switch use at I of the utility model.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model Define.
Refering to fig. 1 to shown in Fig. 3, the utility model provides a kind of simple travel switch of assembly, including switch enclosure 1, company Connector 2, swing rod 3, idler wheel 4, left magnet 5 and right magnet 6, the connector 2 are fixedly mounted on one end of switch enclosure 1, the pendulum One end of bar 3 and the side of connector 2 are hinged, and the other end of the swing rod 3 is hinged with the idler wheel 4, and the one of the switch enclosure 1 Middle side part opens up fluted 7, forms left step 8 and right step 9 on the switch enclosure 1 of 7 both sides of the groove, in the left step 8 Portion is provided with left magnet chamber 10, and 9 middle part of the right step is provided with right magnet chamber, and 8 surface of left step is also pasted with left silica gel Piece 11,9 surface of right step are also pasted with right silica gel piece 12, and 11 middle part of the left silica gel piece offers and left 10 phase of magnet chamber The left opening 13 adapted to, 12 middle part of the right silica gel piece offer the right opening being adapted with right magnet chamber, and left magnet 5 passes through a left side It is embedded in left magnet chamber 10 after opening 13, right magnet 6 is embedded in after passing through right opening in right magnet chamber, 5 outer surface of left magnet Protrusion height be less than the protrusion height of 11 outer surface of left silica gel piece, the protrusion height of 6 outer surface of right magnet is less than right silicon The protrusion height of 12 outer surface of film.In order to make travel switch using when stress be to be parallel to the power of outer metal surface 16, The free cheek of the swing rod 3 has the side of groove 7 parallel with switch enclosure 1.
As shown in fig.4, when in use, travel switch can be adsorbed on to the metal surface 16 of external equipment by magnet On, while silica gel piece is slightly compressed, and ensures that entire silica gel piece is pasted onto metal surface 16, travel switch at work, by Swing rod 3 transmits the power very little of coming, and the free cheek of swing rod 3 is about parallel with metal surface 16, ensure that swing rod 3 transmits and comes Power it is parallel with metal surface 16, silica gel piece is adsorbed on metal watch piece, and silica gel piece and the confficient of static friction of metal surface 16 are very big, So travel switch is at work, power of the timing perpendicular to metal surface 16 is very big, it is also not possible to move travel switch, only When being only more than the adsorption capacity of magnet perpendicular to the pulling force of the metal surface 16, travel switch can be lifted down.So should Travel switch structure is simply easy to use, can be rapidly performed by and be installed on dismounting, while quickly and easily adjust position, be not necessarily to Mounting hole is beaten in metal surface 16, also saves workload when assembly crewman's assembly.
In the present embodiment, the protrusion height difference of 5 outer surface of left magnet and 11 outer surface of left silica gel piece is less than 0.5mm, right 6 outer surface of magnet and the protrusion height difference of 12 outer surface of right silica gel piece are less than 0.5mm.For ensureing that left magnet 5 and right magnet 6 are inhaled When being attached to metal surface 16, silica gel piece is compressed, and entire plane is bonded with metal surface 16, and hole is less, to static friction Power substantially increases.Preferably, difference in height is preferably less than 0.2mm, and difference in height is smaller, and the compressed part of silica gel piece is few, The adsorption capacity for the magnet offset is smaller, and the power that travel switch is extracted from metal surface 16 is then required bigger.
Preferably, the left silica gel piece 7 and right silica gel piece 8 are integral structures, and left silica gel piece 7 and right silica gel piece 8 pass through Upper interconnecting piece 14 and the connection of lower interconnecting piece 15.Due to increasing the area of silica gel piece, so overcoming silica gel piece and metal surface 16 Stiction demand it is bigger, travel switch is more difficult to be slided, holding position stablize.In order to further increase frictional force, institute The outer surface for stating left silica gel piece and right silica gel piece is further opened with reticulate pattern slot.
It is needed on external on-metallic article to cope with, the side surrounding for opening up reeded switch enclosure is also opened Equipped with a pair of of circular hole 16 and a pair of kidney slot 17, and a pair of of circular hole 16 and a pair of of interval of kidney slot 17 are arranged.It is needing to be installed to When non-metal material surface, travel switch can be installed on nonmetallic surface 16 by bolt.
Although being described in conjunction with the accompanying the embodiment of the utility model, patent owner can want in appended right Various deformations or amendments are made within the scope of asking, and model is protected as long as described no more than the claim of the utility model It encloses, should all be within the protection scope of the utility model.
