Mentioned travel switch is because simple in structure in the above-mentioned patent, trigger action is convenient, therefore in actual production, be used widely, whether use morely aspect particularly putting in place for detection of moving component in the weld car automatic production line, and travel switch is installed on the underbody assembly more.But, because the anchor point height on the underbody assembly can not be consistent fully, tend to occur the situation generation of travel switch assembling difficulty, thereby affect the assembling of travel switch, increase workman's labour intensity.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, the travel switch of being convenient to install.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of travel switch of being convenient to install, comprise the travel switch body, and be provided with
The installing rack of installing for described travel switch body;
Be positioned at the mount pad on this installing rack;
Be arranged on this mount pad and the expansion link that matches with described travel switch body.
Further be set to: offer the through hole that wears for expansion link on the described mount pad, described expansion link comprises the bolt that is arranged in slidably in this through hole, and is sheathed on the adjusting nut on this bolt.
Adopt technique scheme, the cooperation of bolt and adjusting nut can realize the adjustment along the axial length of this expansion link, thereby satisfies various installation environment.For the different installation environment of positioning height, only need the simple position of adjusting nut on bolt of adjusting, can realize the length variations of expansion link, thereby change the working depth that expansion link can be responded to, satisfy the needs of various installation environments.
Further be set to: be provided with for driving the back-moving spring of this expansion link along the expansion link axial motion.
Adopt technique scheme, arranging of back-moving spring can guarantee that expansion link can automatically reply original position after removing the jacking force of moving component, with convenient next time pushing tow operation.
Further be set to: described back-moving spring is sheathed on the described bolt, and described adjusting nut and back-moving spring are positioned at the axial two ends of through hole and arrange.
Adopt technique scheme, adjusting nut matches near the induction end setting of travel switch body and with this induction end, and namely when moving component pushing tow bolt, this adjusting nut will be to bumping this induction end and making travel switch produce corresponding signal.
Further be set to: described back-moving spring is arranged with protective sleeve outward.
Adopt technique scheme, the spark that produces when this protective sleeve can protect back-moving spring and expansion link to avoid welding and the sputter damage of welding slag, and then the useful life of prolongation back-moving spring and expansion link.
Further be set to: the end than the travel switch body distal end on the described expansion link is provided with neonychium.
Adopt technique scheme; neonychium is rubber blanket; because the end on the expansion link can produce wearing and tearing after using for a long time; neonychium then can protect the end of expansion link can not cause to the moving component that plays the pushing tow effect infringement of scuffing and so on; and also need not expansion link is carried out integral replacing, thereby cause the waste of resource.
Further be set to again: be arranged with the graphite copper sheathing that is positioned between bolt and through hole on the described bolt.
Adopt technique scheme, the graphite copper sheathing can play protection and lubrication to the motion of bolt in through hole, avoid bolt in through hole wearing and tearing and affect slip, also prolonged the useful life of bolt, avoid unnecessary waste.
The beneficial effects of the utility model are: when the moving component pushing tow was on expansion link, expansion link was along the induction end on self axial motion and the pushing tow travel switch body, thereby triggered the travel switch body.And the expansion link that is positioned at the mount pad through hole can carry out length adjustment as required, can make things convenient for thus the utility model in different installation environments, and particularly the different environment of some positioning heights is installed adjusting, and overall structure is simple, and is easy to operate.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the end view of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, 2, the present embodiment comprises the travel switch body 1 with induction end 11, the installing rack 2 of installing for travel switch body 1, be positioned at the mount pad 3 on this installing rack 2, be arranged on this mount pad 3 and the expansion link 4 that matches with travel switch body 1, be used for driving this expansion link 4 along the back-moving spring 5 of expansion link 4 axial motions.Induction end 11 on the trip Switch main body 1 is swing arm, and arranging of back-moving spring 5 can guarantee that expansion link 4 can automatically reply original position after removing the jacking force of moving component, with convenient next time pushing tow operation.
