Description

Technical Field

[0001] The present application relates to the technical field of trippers, and in particular to a tripper fixing structure. Background Art

[0002] The trip unit is mechanically connected to the circuit breaker and is used to release the holding mechanism and automatically open the circuit breaker. Its function is to prevent electric shock and leakage by generating a voltage across the transformer's secondary coil when the vector sum of the currents through the zero-sequence current transformer is not equal to zero. This voltage is amplified by the integrated circuit and, when the voltage reaches the set value, the leakage current release cuts off the power supply within 0.1 seconds.

[0003] The installation location of the trip unit depends on the specific application scenario and the type of electrical equipment used. The trip unit is commonly installed inside a circuit breaker, in a distribution box or distribution cabinet, in a switch cabinet, and in a motor control center. The trip unit is installed in a distribution box or distribution cabinet, mostly by being mounted on a specific guide rail or mounting plate, and used in conjunction with other electrical components.

[0004] Existing trip units are typically fixed to the mounting plate with screws. Therefore, subsequent disassembly and maintenance requires the use of external tools to loosen the screws before removing the trip unit. This is inconvenient overall. Repeated disassembly and assembly or overtightening the screws can cause the screws to slip within the screw holes, affecting the securing effect. Therefore, a trip unit fixing structure is needed to address this issue.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0006] Based on the above-mentioned problems existing in the prior art, the problem to be solved by this application is: to provide a tripper fixing structure to solve the problem that the existing tripper is generally fixed to the mounting plate with screws. Therefore, for subsequent disassembly and maintenance, it is necessary to use external tools to loosen the screws to remove the tripper, which is inconvenient overall. At the same time, repeated disassembly or over-tightening of the screws may cause the screws to slip in the screw holes, affecting the fixing effect.

[0007] The technical solution adopted by this application to solve the technical problem is: a tripper fixing structure. It mainly includes: a fixing structure with a mounting plate, comprising a storage box mounted on the mounting plate; two sets of limiting blocks mounted in the storage box; a connecting assembly mounted on the tripper, comprising: a side connecting plate mounted on the tripper, with a recessed block plate mounted on the side connecting plate; a circular shaft mounted on the recessed block plate, with a hanging rod movably sleeved on the circular shaft; and a buckle block mounted on the storage box.

[0008] Furthermore, a handle is installed on the hanging rod.

[0009] Furthermore, an inner groove is provided at the bottom end of the inner wall of the storage box, and two sets of clamping mechanisms are installed in the inner groove. The clamping mechanism includes a support plate arranged in the inner groove, and a spring is provided between the support plate and the storage box.

[0010] Furthermore, a straight rod is installed on the support plate.

[0011] Furthermore, ventilation holes are provided on the storage box and the mounting plate.

[0012] The beneficial effect of the present application is that the present application provides a trip device fixing structure, which is easier to install and disassemble than fixing the trip device with screws through the arrangement of a mounting plate, a storage box, a limiting block, a side connecting plate, a recessed block plate, a round shaft, a hanging rod, a handle and a buckle block.

[0013] In addition to the above-described purposes, features and advantages, the present application also has other purposes, features and advantages. The present application will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0023] like Figure 1-Figure 3 As shown, the present application provides a trip unit fixing structure, including a fixing structure 2, the fixing structure 2 including a mounting plate 201 mounted in a switch cabinet, a storage box 202 fixedly mounted on the mounting plate 201, the storage box 202 is in an open state, and a trip unit body 1 is placed in the storage box 202;

[0024] Two sets of limiting blocks 203 are fixedly installed on both sides of the inner wall of the storage box 202. The two sets of limiting blocks 203 are used to limit the storage of the trip unit body 1 in the storage box 202. An inner groove 205 is opened on the inner wall of the storage box 202. Two sets of clamping mechanisms are installed in the inner groove 205. The clamping mechanisms are arranged on the upper and lower surfaces of the trip unit body 1.

[0025] The clamping mechanism includes a support plate 207 disposed in the inner groove 205, the support plate 207 having two sets of arc surfaces, and a spring 208 disposed between the support plate 207 and the storage box 202. One end of the spring 208 is connected to the support plate 207, and the other end of the spring 208 is connected to the storage box 202. The support plate 207 is adapted to be clamped in the storage box 202 under the action of the spring 208.

[0026] A straight rod 209 is fixedly mounted on the support plate 207. The straight rod 209 passes through the interior of the spring 208, and one end of the straight rod 209 movably passes through the mounting plate 201. The straight rod 209 is suitable for limiting the movement of the support plate 207 in the vertical direction.

[0027] Both the storage box 202 and the mounting plate 201 are provided with ventilation holes 206, which facilitate heat dissipation when the trip unit 1 is in use;

[0028] A connecting assembly 3 is mounted on the trip body 1. The connecting assembly 3 includes side connecting plates 301 fixedly mounted on both sides of the trip body 1. Concave blocks 302 are fixedly mounted on the side connecting plates 301. A round shaft 303 is mounted on the concave blocks 302. A hanging rod 304 is movably sleeved on the round shaft 303. A buckle block 306 adapted for use with the hanging rod 304 is fixedly mounted on the storage box 202.

[0029] A handle 305 is fixedly mounted on the hanging rod 304, and the handle 305 facilitates the rotation of the hanging rod 304;

[0030] Working principle:

[0031] When installing the trip unit 1, first pull the straight rod 209 to move the support plate 207 downward, then engage the trip unit 1 in the storage box 202 through the four sets of limit blocks 203, and then loosen the straight rod 209. At this time, the two sets of support plates 207 clamp the trip unit 1 under the action of the spring 208. Then, by holding the handle 305 and rotating the hanging rod 304, the hanging rod 304 is hooked on the buckle block 306, thereby fixing the trip unit 1 on the storage box 202. Compared with fixing with screws, installation and removal are much simpler.

[0032] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
