Hanging basket travel switch with dust cover

Abstract

A hanging basket travel switch with a dust cover comprises a travel switch body which is vertically arranged and is in a cuboid shape, a cylindrical contact which is vertically arranged and exceeds the travel switch body is arranged on the upper side of the travel switch body, a concave threaded blind hole is formed in the top of the contact, and the threaded blind hole and the contact are coaxially arranged. A dust cover is arranged on the outer side of the travel switch body and is integrally in a cuboid shape matched with the travel switch body in length and width, the lower side of the dust cover is open, a counter bore matched with the threaded blind hole is formed in the position, corresponding to the threaded blind hole, of the top of the dust cover, and the dust cover is arranged on the outer side of the travel switch body in a sleeving mode from top to bottom. A counter bore in the dustproof cover is right opposite to a threaded blind hole in the top of the contact, the dustproof cover and the contact are locked and fixed through a countersunk bolt matched with the threaded blind hole and the counter bore, and the vertical height of the dustproof cover is large enough to cover the travel switch body and the contact. And through the dust cover, the contact of the travel switch can be protected, and foreign matters in the construction stage are prevented from being contacted with the contact.

Description

Technical Field

[0001] The utility model relates to a hanging basket travel switch with a dust cover. Background Art

[0002] The hanging basket is widely used in the construction of building facades. See Chinese patent CN102381611B. The existing hanging basket is equipped with a variety of lifting guide limit protection devices; it has multiple safety protection functions such as double safety lock protection device, contour limit protection device, overweight limit protection device, lifting guide limit protection device, manual descending device, top escape device, ringing, warning light, access control switch, etc. Among them, the travel switch used to control the lifting limit is exposed to the outside. During construction, the gap around the contact or push rod is often blocked by splashing real stone paint and other materials, making the contact unable to effectively control and limit the mechanical travel, which is prone to derailment and other dangers, posing a great safety hazard. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a hanging basket travel switch with a dust cover, through which the contacts of the travel switch can be protected to prevent foreign matter from contacting the contacts during the construction stage.

[0004] In order to solve the above technical problems, the utility model provides a hanging basket travel switch with a dust cover, comprising a travel switch body arranged vertically and in the shape of a rectangular parallelepiped, a cylindrical contact arranged vertically and exceeding the travel switch body is provided on the upper side of the travel switch body, an inwardly concave threaded blind hole is provided on the top of the contact, the threaded blind hole and the contact are arranged coaxially, a dust cover is provided on the outside of the travel switch body, the dust cover as a whole is in the shape of a rectangular parallelepiped matching the length and width of the travel switch body, the lower side of the dust cover is open, a countersunk hole matching the threaded blind hole is provided at the top position of the dust cover corresponding to the threaded blind hole, the dust cover is sleeved on the outside of the travel switch body from top to bottom, and the countersunk hole on the dust cover is directly opposite to the threaded blind hole on the top of the contact, the dust cover and the contact are locked and fixed by countersunk bolts matching the threaded blind hole and the countersunk hole, and the vertical height of the dust cover is sufficient to cover the travel switch body and the contact.

[0005] Advantages of the utility model: the utility model provides a hanging basket travel switch with a dust cover, which can protect the contacts of the travel switch and prevent the gaps around the contacts from being blocked by debris, resulting in the contacts being unable to effectively control and limit the mechanical travel, causing dangers such as derailment, and also prolonging the service life of the travel switch. In addition, the dust cover and the contacts are fastened with countersunk bolts, which not only ensures that the upper side of the dust cover is flat and does not affect the normal triggering of the travel switch, but also makes it easy to disassemble and replace the dust cover when it is damaged.

[0009] See also Figure 1-3 A hanging basket travel switch with a dust cover comprises a travel switch body 1 arranged vertically and in a rectangular parallelepiped shape, a cylindrical contact 11 arranged vertically and exceeding the travel switch body 1 is provided on the upper side of the travel switch body 1, a concave threaded blind hole 12 is provided on the top of the contact 11, and the threaded blind hole 12 is coaxially arranged with the contact 11, a dust cover 2 is provided on the outer side of the travel switch body 1, and the dust cover 2 is in a rectangular parallelepiped shape matching the length and width of the travel switch body 1 The lower side of the dust cover 2 is open, and a countersunk hole 21 matching the threaded blind hole 12 is provided at the top position of the dust cover 2 corresponding to the threaded blind hole 12. The dust cover 2 is sleeved on the outside of the travel switch body 1 from top to bottom, and the countersunk hole 21 on the dust cover 2 is directly opposite to the threaded blind hole 12 at the top of the contact 11. The dust cover 2 and the contact 11 are locked and fixed by countersunk bolts 3 matching the threaded blind hole 12 and the countersunk hole 21. The vertical height of the dust cover 2 is sufficient to cover the travel switch body 1 and the contact 11.
