Description

Technical Field

[0001] The utility model relates to the field of transformer brackets, in particular to a plasma transformer bracket. Background Art

[0002] Plasma ignition transformers are mainly used in the ignition system of burners to achieve automatic ignition of burners. Their functions include voltage conversion, current conversion, main reactor conversion, isolation, and voltage stabilization. They can help thermal power plants save energy and reduce emissions, and reduce losses.

[0003] The Chinese invention patent with publication number CN217788139U discloses a transformer bracket that is easy to install, including a base plate, two groups of columns are fixedly set on the top of the base plate, a baffle is fixedly set at the bottom between the two groups of columns, a lifting platform is movably set on the top, and an electric adjustment part for controlling its lifting is set at the bottom of the lifting platform, and side frames are fixedly set on the left and right sides of the top of the lifting platform.

[0004] However, the above patent has the following shortcomings:

[0005] 1. The above patent uses a driving assembly to compress the sliding blocks in the side frames on both sides, compressing the springs so that the upper and lower sets of movable rods are separated from the mounting plate, so that the transformer body is no longer restricted, thereby making the transformer disassembly and assembly very convenient. However, the above device only fixes the transformer body by squeezing the mounting plate with spring pressure. However, it is difficult to fix the transformer body stably using only this method. After long-term use, the transformer is at risk of shaking or even falling.

[0006] 2. In the above device, the electric adjustment part can first control the up and down movement of the lifting platform, making the disassembly and assembly of the device very convenient and facilitating subsequent replacement and maintenance. However, the motor of the electric adjustment part is exposed on the outside of the device. When it rains outside, the motor may be damaged due to getting wet. Utility Model Content

[0007] The purpose of the utility model is to provide a plasma transformer bracket, which can pre-fix the transformer through the elastic force of the spring and the fixing plate by setting a fixing mechanism, and at the same time cooperate with the self-locking mechanism to self-lock the transformer when the transformer is raised to a predetermined position, thereby facilitating the improvement of the fixing strength of the transformer to solve the above-mentioned deficiencies in the technology.

[0008] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a plasma transformer bracket, comprising a base, a lifting mechanism, a fixing mechanism and a self-locking mechanism;

[0009] The top of the base is fixedly connected to two sides with a fixing frame, and the bottom of the base is fixedly connected to a mounting compartment;

[0014] The mounting plate is arranged on the top of the driving sleeve, and a plurality of fixing rods are fixedly connected between the mounting plate and the driving sleeve;

An extrusion spring is fixedly connected to the top of the stop block, and the bottom of the extrusion spring abuts against the stop block, and the top of the extrusion spring abuts against the inner wall of the groove;

[0018] By pulling the fixing plate upward, the fixing plate can be driven to move upward between the two fixing columns. At this time, the blocks on both sides of the fixing plate will squeeze and compress the extrusion spring. At this time, the transformer to be fixed can be placed on the top of the mounting plate. Then, the fixing plate is released. At this time, the compressed extrusion spring will rebound, thereby driving the fixing plate to move downward until the fixing plate is against the top of the transformer, so that the transformer can be pre-fixed.

[0020] The locking member is L-shaped, and the number of the locking members is two. The two locking members are fixedly connected to the two fixing frames respectively, and the locking members match the handle;

[0021] When the mounting plate is lifted upward, the two fixing plates on its top will also be driven and lifted upward until it reaches a certain height. The bottom of the locking piece on one side of the fixing frame will engage with the handle. At this time, the handle and the fixing plate will be completely fixed, thereby improving the fixing strength of the transformer between the two fixing plates.

[0027] 1. By setting up a fixing mechanism, the transformer can be pre-fixed by the elastic force of the spring and the fixing plate. At the same time, with the self-locking mechanism, the transformer can be self-locked when it is raised to the predetermined position, which is beneficial to improve the fixing strength of the transformer;

[0028] 2. The sliding rod can be used to limit the limit sleeve and the mounting plate connected to the limit sleeve, so that the mounting plate can slide along the direction of the sliding rod, thereby improving the stability of the mounting plate when sliding. By setting up the mounting compartment, the stepper motor can be protected, thereby preventing the stepper motor from being damaged by external rain and the like. BRIEF DESCRIPTION OF THE DRAWINGS
