CN101964279A - Electronic overload relay preventing bracket in mechanism from releasing - Google Patents

Abstract

The invention relates to an electronic overload relay preventing a bracket in a mechanism from releasing, which is characterized by comprising an electronic overload relay base, a bracket and a base, wherein the base is provided with a column, a round groove at the bottom end of the bracket is sleeved on the column of the base, the base is also provided with a guide rod capable of blocking the upper end of the bracket from releasing, and a protruding small baffle plate capable of blocking the bottom end of the bracket sleeved on the column of the base from releasing from the column. Because the small baffle plate of the base blocks the bottom end of the bracket, the bracket can not release from the mechanism, and the mechanism can act reliably.

Description

The electronic overload relay that anti-locking mechanism medium-height trestle is deviate from

Technical field

The invention belongs to a kind of electronic overload relay, particularly relate to the electronic overload relay that a kind of anti-locking mechanism medium-height trestle is deviate from.

Background technology

Medium-height trestle is deviate from from mechanism easily in present known TR40 electronic overload relay mechanism, causes mechanism's cisco unity malfunction.

Summary of the invention

The electronic overload relay that the present invention deviates from for the anti-locking mechanism medium-height trestle that the technical problem that exists in the solution known technology provides a kind of support to deviate from from mechanism easily.

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: it includes electronic overload relay pedestal, support and base, one cylinder is arranged on the described pedestal, described support bottom circular groove is enclosed within on the cylinder of described pedestal, on described pedestal, also have one can block the unlikely guide rod of deviating from described support upper end, having an outstanding described support bottom that is enclosed within on the pedestal cylinder of blocking to make it the unlikely small front apron of deviating from from described cylinder on the described base.

Advantage and good effect that the present invention has are: owing to adopted the small front apron with base to keep off in the bottom of support, support will can not deviate from from mechanism again, and mechanism can action message.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Embodiment

For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

As shown in Figure 1, one cylinder 1 is arranged on the electronic overload relay pedestal 5, and support 2 bottom circular grooves are enclosed within on the cylinder 1 of pedestal, and an outstanding small front apron 4 is arranged on the base 6, retaining is in the bottom of support 2, has one to be fixed on the upper end that guide rod 3 in pedestal 5 grooves blocks support 2.

Claims (1)

1. electronic overload relay that anti-locking mechanism medium-height trestle is deviate from, it includes electronic overload relay pedestal, support and base, one cylinder is arranged on the described pedestal, described support bottom circular groove is enclosed within on the cylinder of described pedestal, on described pedestal, also have one can block the unlikely guide rod of deviating from described support upper end, it is characterized in that: having an outstanding described support bottom that is enclosed within on the pedestal cylinder of blocking to make it the unlikely small front apron of deviating from from described cylinder on the described base.
