Fixing lock

Abstract

The invention relates to a lock of a plate fixed heating unit device, in particular to a fixing lock for firmly combining the plate fixed heating unit device and a mounting face. The fixing lock is arranged in the plate fixed heating unit device which is connected with the mounting face through the fixing lock and a fixing rod. The fixing lock comprises a magnetic block, a fixed support, a movable clamping hand and an error omission support. The error omission support is arranged in the plate fixed heating unit device, a slide groove is formed in the error omission support, and the fixed support is arranged on the error omission support, the magnetic block is arranged in the fixed support, the movable clamping hand comprises a first edge and a second edge which are connected. The second edge is accommodated in the slide groove, slides in a reciprocating mode in the radial direction and is in butting joint with the fixing rod, the first edge is in butting joint with the fixed support and clamps the magnetic block in the fixed support. The fixing lock is clamped on clamping grains through the movable claming hand and is firmly fixed, and is not influenced by the thickness of the fixing rod, and the service life of the plate fixed heating unit device is prolonged.

Description

technical field [0001] The invention relates to a lock for a plate-fixed heating unit device, in particular to a lock for firmly joining a plate-fixed heating unit device with an installation surface. Background technique [0002] In the Chinese invention patent with the publication date of December 14, 2011 and the publication number CN102278787A, the title of the invention is "Plate Fixed Heating Unit Device", which discloses a fixed lock applied to the plate fixed heating unit device. [0003] The fixed lock is mainly composed of bracket cover plate, spring, steel ball bracket, stainless steel ball, mobile bracket and other components. The grooves coincide with each other, and the stainless steel balls in the steel ball bracket will move inward, so that the stainless steel balls are tightly squeezed on the card pattern of the fixing rod, and the fixing of the heating unit device fixed by the original plate is completed; when the strong magnet of the dismantler attracts T...

AI Technical Summary

Problems solved by technology

[0004] When the original plate is fixed to the heating unit and installed on the installation surface, the fixed lock and the fixed rod are fixed. Since the stainless steel ball in the fixed lock is fixed to the clamping part of the fixed rod, the stainless steel ball with a curved surface and the fixed rod may not be firmly fixed. , prone to loosening, which affects the service life of the plate fixed heating unit

[0005] The fixed lock of the original panel fixed heating unit requires the use of a fixed rod with a small diameter and low strength, which cannot be applied to the large-sized panel fixed heating unit device.

[0006] When installing the heating unit fixed by the original plate, the fixed lock cannot be guaranteed to be in the center of the groove of the unit bracket, resulting in a larger error when the fixed rod and the fixed lock are fixed, and it cannot be installed smoothly.

[0007] The thickness required for the fixed lock used in the original plate fixed heating unit device is relatively high, which affects the overall thickness of the plate fixed heating unit device, and cannot meet the requirements of thinner plate fixed heating unit devices
