Description

Technical Field

[0001] The utility model relates to the technical field of proximity switches, in particular to a proximity switch with an end protection sleeve. Background Art

[0002] A proximity switch is an electronic component that is usually used to detect the approach or arrival of an object. This switch can change its state according to the distance or proximity of a nearby object. It is often used in automation systems. Among them, a proximity switch with an end protective sleeve is a specially designed proximity switch with a protective sleeve attached to its end to enhance its durability and safety. This protective sleeve is usually made of wear-resistant material or protective plastic, and is designed to protect the sensor part of the proximity switch from the influence of the external environment or damage caused by collision with an object.

[0003] The existing proximity switches with end protective covers use protective covers for protection, but protective covers of specific sizes can only be adapted to proximity switches of specific sizes. When the proximity switch models are different, protective covers of different sizes need to be replaced, which is not convenient to use. Secondly, due to the different installation positions of the proximity switches, the locking nut buckle used to fix the outer side is divided into two sections of different lengths. When the protective cover is used for installation, it is necessary to cut the protective cover according to the actual length, which is time-consuming and labor-intensive.

[0004] Therefore, we provide a proximity switch with an end protection sleeve. Utility Model Content

[0005] The purpose of the utility model is to provide a proximity switch with an end protection sleeve to solve the problems raised in the above background technology.

[0007] The protective kit includes a main fixing buckle, a secondary fixing buckle, a splint and an extension buckle. The outer fixing sleeve of the proximity switch is provided with a main fixing buckle, a secondary fixing buckle is rotatably installed on one side of the main fixing buckle, a splint is elastically installed on the inner sides of the main fixing buckle and the secondary fixing buckle, and an extension buckle is slidably installed inside the main fixing buckle and the secondary fixing buckle.

[0008] Preferably, a fixing seat is welded to the lower end of the main fixing buckle, a rotating shaft seat is welded to the lower end of the auxiliary fixing buckle, and the rotating shaft seat is rotatably mounted on the inner side of the fixing seat.

[0009] Preferably, a main fixing plate is welded to the upper end of the main fixing buckle, a main fixing hole is penetrated through the side of the main fixing plate, and a secondary fixing plate is welded to the upper end of the secondary fixing buckle, a secondary fixing hole is penetrated through the side of the secondary fixing plate, and fixing bolts are penetrated and installed inside the main fixing hole and the secondary fixing hole.

[0010] Preferably, a slot is provided on one side of the main fixing buckle, and the extension buckle is slidably installed inside the slot.

[0011] Preferably, a limiting groove is provided through the upper end of the slot and on the inner side of the main fixing plate, a connecting plate is welded to the upper end of the extension buckle, limiting blocks are welded at both ends of the inner side of the connecting plate, and the limiting blocks are slidably installed inside the limiting groove.

[0012] Preferably, a spring is welded on the inner side of the clamping plate, and the other end of the spring is welded to the inner sides of the main fixing buckle and the auxiliary fixing buckle.

[0013] Preferably, the protective cover comprises protective shell one, a rubber cover and protective shell two, the protective shell one is welded to the outer side of the rear end cover, the other end of the protective shell one is fixedly connected to the rubber cover, and the other end of the rubber cover is fixedly connected to the protective shell two.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The proximity switch with the end protection cover is provided with a main fixing buckle, a secondary fixing buckle and a clamping plate. After the proximity switch is installed, the main fixing buckle and the secondary fixing buckle are sleeved on the outside of the proximity switch. At this time, the clamping plate is in direct contact with the outside of the proximity switch. When the main fixing buckle and the secondary fixing buckle are buckled with each other, the spring is compressed, thereby increasing the clamping space between the main fixing buckle and the secondary fixing buckle. At the same time, the spring releases elastic force in the opposite direction while being compressed, thereby firmly fixing the main fixing buckle and the secondary fixing buckle on the outside of the proximity switch. This structure can be applicable to proximity switches of different diameters and has stronger applicability.

[0016] 2. Through the setting of the extension buckle, the locking nut buckle used to fix the outside of the proximity switch is divided into two distances of different lengths. At this time, the length of the extension buckle extending out of the slot can be adjusted according to the actual length to adapt to different lengths of protection distances. Compared with the traditional size cutting of the protective cover, it saves time and effort, is easy to install and disassemble, and can be reused, which increases its practicality and economy.

In the second step, first buckle the main fixing buckle 21 and the auxiliary fixing buckle 22 on the outside of the proximity switch 1, and adjust the extension length of the extension buckle 24 according to the required degree of protection until the overall length between the two groups of main fixing buckles 21 and one group of extension buckles 24 is sufficient to protect the outside of the proximity switch 1. In the third step, buckle the protective cover 2 on the outside of the cable 11. During use, since a rubber cover 42 is connected between the protective shell 1 41 and the protective shell 2 43, the protective cover 4 can be reasonably adjusted according to the bending degree of the cable 11. In the fourth step, pass the fixing bolt 25 through the main fixing hole 213 and the auxiliary fixing hole 223 to fix the main fixing plate 212 and the auxiliary fixing plate 222.
