Description

Technical Field

[0001] This utility model belongs to the field of electrical component installation technology, and particularly relates to electrical component installation structure. Background Technology

[0002] Electrical components refer to various auxiliary equipment used to work in conjunction with power systems or equipment, including wires, cables, switches, sockets, fuses, circuit breakers, transformers, terminal blocks, etc. These components together form a complete electrical system, undertaking important responsibilities such as connection and protection. The main switch is also a type of electrical component, and an installation structure is required when installing it.

[0003] Most existing electrical component installation structures use bolts to directly fix the main switch to the mounting plate inside the electrical box. However, the space inside the electrical box is limited, and multiple sets of bolts need to be fixed one by one during installation, which is very inconvenient. It is impossible to use a quick snap-locking method to install it quickly, which greatly reduces the installation speed. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an electrical component installation structure, which solves the problem that electrical components cannot be quickly installed using a snap-fit ​​locking method.

[0005] This utility model is implemented as follows: an electrical accessory installation structure includes a heat sink embedded in a mounting plate, and a main switch attached to the front of the heat sink. Both sides of the main switch are fixed with strip blocks whose backs are attached to the heat sink. Each set of strip blocks has a slot on its back. Both sides of the front of the heat sink are fixed with card holders that engage with the slots. Each set of card holders has a top block fixed on it, with the top of the top block penetrating the strip block and extending upwards. The card holder is provided with a self-locking component that cooperates with the strip block.

[0006] As a preferred embodiment of this utility model, the self-locking assembly includes a vertical shaft rotatably mounted on the card seat and the top block. A baffle plate and a base plate are respectively fixed to the top and bottom ends of the vertical shaft. The bottom of the baffle plate is attached to the strip block. A T-shaped rod is inserted into the front of the bottom of each set of base plates. The back of each set of T-shaped rods is attached to the strip block. A spring is wound around each set of T-shaped rods. The two ends of the spring are fixed to the bottom of the base plate and the protruding bottom end of the T-shaped rod.

[0007] As a preferred embodiment of this utility model, the shielding plate and the top block are in the form of a cross shape, and the longitudinal length and lateral width of the shielding plate are both smaller than the lateral length and longitudinal width of the top block.

[0008] As a preferred embodiment of this invention, a gap is reserved between the back of the base plate and the heat sink.

[0009] As a preferred embodiment of this invention, both the card holder and the top block are equipped with auxiliary bearings, and the surface of the vertical shaft is fixed on the inner ring of the auxiliary bearing.

[0010] As a preferred embodiment of this utility model, each set of card holders has a T-shaped structure, and the horizontal length of the front side of the card holder is greater than the horizontal length of the back side of the card holder.

[0011] As a preferred embodiment of this utility model, a pressure plate is fixed to the bottom of the front side of the T-shaped rod, and a through hole is provided at one end of the pressure plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a self-locking component, employing a locking mechanism between the locking channel and the locking seat, to initially position the main switch and the heat sink. A rotatable axis allows for adjustments to the positions of the baffle and the base plate. Simultaneously, a spring and a T-shaped rod quickly form a locking structure for the base plate, preventing unauthorized rotation and thus quickly limiting the baffle's position. At this point, the baffle and the top block form a cross-shaped structure, allowing for quick locking and securing of the locking seat and the strip block, preventing detachment. This enables rapid fixation of the main switch and the heat sink. The entire assembly process uses a locking mechanism, facilitating rapid installation of electrical components and improving installation efficiency. Attached Figure Description

[0019] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 3As shown, the electrical accessory installation structure provided in this embodiment of the utility model includes a heat sink 1 embedded in the mounting plate, and also includes a main switch 2 attached to the front of the heat sink 1. Both sides of the main switch 2 are fixed with strip blocks 3 whose backs are attached to the heat sink 1. Each set of strip blocks 3 has a slot 4 on its back. Both sides of the front of the heat sink 1 are fixed with a card seat 5 that engages in the slot 4. Each set of card seats 5 is fixed with a top block 9, and the top of the top block 9 passes through the strip block 3 and extends upward. By engaging the slot 4 and the card seat 5, the main switch 2 and the heat sink 1 can be initially positioned. The card seat 5 is provided with a self-locking component that works with the strip block 3. By setting the self-locking component, the entire assembly process adopts a locking method, which can quickly install electrical accessories and improve installation efficiency.

[0022] As a preferred embodiment of this utility model, the self-locking assembly includes a vertical shaft 6 rotatably mounted on the card holder 5 and the top block 9. A baffle plate 7 and a base plate 8 are fixed to the top and bottom ends of the vertical shaft 6, respectively. The bottom of the baffle plate 7 is attached to the strip block 3. A T-shaped rod 10 is inserted into the front of the bottom of each set of base plates 8. The back of each set of T-shaped rods 10 is attached to the strip block 3. A spring 11 is wound around each set of T-shaped rods 10. The two ends of the spring 11 are fixed to the bottom of the base plate 8 and the protruding bottom end of the T-shaped rod 10. The design of the spring 11 and the T-shaped rod 10 can form a locking structure for the base plate 8, so as to quickly limit the position of the baffle plate 7 after rotation, thereby quickly locking the card holder 5 and the strip block 3, and then quickly fixing the main switch 2 and the heat sink 1.

[0023] As a preferred embodiment of this utility model, the shielding plate 7 and the top block 9 are in the shape of a cross. The longitudinal length and lateral width of the shielding plate 7 are both smaller than the lateral length and longitudinal width of the top block 9, so that the shielding plate 7 can be quickly rotated to the top block 9 and can be given a certain small movement distance, which helps the shielding plate 7 to stably penetrate the strip block 3.

[0024] As a preferred embodiment of this utility model, a gap is reserved between the back of the base plate 8 and the heat sink 1. The gap is designed to provide sufficient rotation space for the base plate 8, allowing it to rotate without obstruction and preventing it from contacting and colliding with the heat sink 1 during rotation.

[0025] As a preferred embodiment of this utility model, auxiliary bearings are embedded in both the card holder 5 and the top block 9. The surface of the vertical shaft 6 is fixed on the inner ring of the auxiliary bearing. The design of the auxiliary bearing can position the vertical shaft 6 while assisting it to rotate stably.

[0026] As a preferred embodiment of this utility model, each set of card holders 5 has a T-shaped structure, and the horizontal length of the front side of the card holder 5 is greater than the horizontal length of the back side of the card holder 5, so that the card holder 5 can stably perform initial snap-fit ​​positioning of the strip block 3.

[0027] As a preferred embodiment of this utility model, a pressure plate is fixed to the bottom of the front of the T-shaped rod 10, and a through hole is provided at one end of the pressure plate. The design of the pressure plate and the through hole makes it convenient for the user to change the position of the T-shaped rod 10 and to quickly release the locking state of the T-shaped rod 10 to the base plate 8.

[0028] The working principle of this utility model:

[0029] refer to Figures 1 to 3 The user first places the main switch 2 between the two sets of card slots 5, and then moves the main switch 2 down until the card slot 4 on the strip block 3 is fully engaged with the card slot 5, initially positioning the main switch 2 and the heat sink 1. As the strip block 3 moves down, it will pre-contact the T-shaped rod 10, driving it to move down as well, simultaneously stretching the spring 11. At this time, the counterforce of the spring 11 prevents the baffle plate 7 and the base plate 8 from moving arbitrarily as the strip block 3 moves down, until the baffle plate 7 is above the strip block 3. The user rotates the baffle 7, which drives the base plate 8 and the T-shaped rod 10 to rotate synchronously until the baffle 7 and the top block 9 form a cross-shaped structure. At this time, the elastic rebound of the spring 11 can drive the T-shaped rod 10 to move upward and fit against the front of the strip block 3, thereby quickly locking the position of the base plate 8, and then quickly locking the baffle 7, which can then quickly fix the main switch 2 and the heat sink 1. The entire assembly process adopts a snap-fit ​​locking method, which can quickly install electrical components and improve installation efficiency.
