Abstract
The utility model relates to a novel proximity switch which especially belongs to a proximity switch with an auxiliary protection device. The novel proximity switch is composed of a proximity switch (3) and a protection device at the peripheral of the proximity switch. The novel proximity switch is characterized in that the protection device includes a crashproof cap (1), a buffer spring (2), a fixing cover (4) and an adjusting nut (5); the proximity switch is placed in the fixing cover; the buffer spring is sleeved on the proximity switch; one end of the buffer spring is supported on a blocking wall of the fixing cover and the other end of the buffer spring is supported on the tail portion of the crashproof cap; the crashproof cap has an arc-shaped head and is cooperated with the proximity switch through screw threads; and the adjusting nut is positioned outside the blocking wall of the fixing cover and is in screw thread cooperation with the proximity switch. The positive effects are that the novel proximity switch can be protected and is convenient to mount and dismount.
Description
Technical field
The utility model relates to a kind of novel approach switch, belongs to especially a kind of approach switch with attached protective device.
Background technology
Approach switch claims again contactless proximity switch, is used in general Stroke Control, has that long service life, reliable operation, repetitive positioning accuracy are high, characteristics such as machinery-free wearing and tearing, no-spark, noiselessness, vibration resistance are strong.Therefore up to the present the range of application of approach switch is increasingly extensive.But in actual applications; minor impact occurs in the moving component that often can occur being controlled or detecting when close above-mentioned approach switch; again because it is to be fixedly connected with structural member; so even slight impact also can cause the detection head damage; cause unnecessary economic loss and time waste, also very likely cause mechanical disorder and cause security incident.
Summary of the invention
The purpose of this utility model namely is to provide a kind of novel approach switch, to reach the purpose of protection approach switch and easy disassembly.
Novel approach switch provided by the utility model is made of approach switch and peripheral protector thereof, it is characterized in that, described protector comprises Anti-collision cap, buffer spring, fixed cover and adjusting nut; Approach switch is positioned in fixed cover, and buffer spring is sleeved on approach switch, and buffer spring one end withstands on the retaining wall of fixed cover, and the other end withstands on the afterbody of Anti-collision cap; The Anti-collision cap head is circular-arc, passes through threaded engagement with approach switch; Adjusting nut is positioned at the retaining wall outside of fixed cover, with the approach switch threaded engagement.
The utility model is fixedly connected on fixed cover on structural member in use, namely completes installation.When Anti-collision cap is installed, make its head end slightly exceed the detection head of approach switch, or concordant with it.Because the Anti-collision cap head is circular-arc, and the existence of buffer spring, when the moving component of being controlled or detecting touches approach switch, can well play a protective role.Unfixing dead because of approach switch again, Anti-collision cap is enough large again, can carry out fully by hand when dismounting, does not need other aids.So, the utlity model has the good effect of protecting approach switch and easy disassembly.
Description of drawings
Accompanying drawing partly discloses specific embodiment of the utility model, wherein,
Fig. 1, front view of the present utility model;
Fig. 2, internal mechanism generalized section of the present utility model.
Embodiment
As shown in the figure, novel approach switch provided by the utility model is made of Anti-collision cap 1, buffer spring 2, fixed cover 4 and adjusting nut 5.Fixed cover is used for being fixedly connected on device structure spare, and the approach switch 3 that puts buffer spring is arranged in fixed cover.Buffer spring one end withstands on the retaining wall of fixed cover, and the other end withstands on and the Anti-collision cap afterbody of approach switch by threaded engagement.It is circular-arc that the Anti-collision cap head is; can slightly exceed the detection head of approach switch during installation; when being subject to the shock of different directions, approach switch can well play a protective role; Anti-collision cap afterbody outer rim and fixed cover inboard are matched in clearance, and rocking by a relatively large margin can not be arranged again when can sliding.
Installation of the present utility model is by fixed cover realization indirectly, and unfixing dead because of approach switch, Anti-collision cap is enough large again, can carry out fully by hand when dismounting, does not need other aids.
Adjusting nut is positioned at the retaining wall outside of fixed cover, passes through threaded engagement with approach switch.Adjusting nut can be regulated the size of buffer spring bounce-back dynamics and the length of cushion stroke according to actual needs.
Claims (1)
