Description

Technical Field

[0001] The utility model relates to the technical field of thermal overload relays, and particularly relates to a base of a thermal overload relay which is convenient to install. Background Art

[0002] The base of a thermal overload relay is a device for fixing and supporting the thermal overload relay. The thermal overload relay is usually used to protect motors or other electrical equipment from damage caused by overcurrent. This relay monitors the current in the circuit and disconnects the circuit when detecting a current exceeding the safety threshold, thereby protecting the equipment from damage.

[0003] The base of the thermal overload relay provides a stable and safe installation platform for it, ensuring that the relay can correctly perform its protection function. The design of the base needs to consider the size of the relay, the installation method (such as screw fixation, snap fixation, etc.) and the requirements of electrical connection.

[0004] The existing relay bases are inconvenient to install and cannot be adjusted according to the size of the installation rail, resulting in low installation applicability. Summary of the Utility Model

[0005] The utility model aims to provide a base of a thermal overload relay which is convenient to install, so as to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A base of a thermal overload relay which is convenient to install, comprising a relay base. A clamping groove is provided at the bottom of the relay base. A movable buckle is movably provided at the front of the clamping groove, and a fixed buckle is provided at the rear of the clamping groove. An inner cavity is provided at the front of the relay base. A driving gear is rotatably provided inside the inner cavity. Transmission gears are meshed on both sides of the driving gear. Two sliding grooves are arranged in parallel on both sides of the surface of the clamping groove. Lead screws are rotatably provided in the sliding grooves. The lead screws are connected with the transmission gears. Sliders are provided on both sides of the top of the movable buckle. The sliders are slidably arranged in the sliding grooves and are screwed with the lead screws.

[0008] Preferably, a cover plate is provided at the front of the inner cavity, and a through hole is provided in the middle of the surface of the cover plate.

[0009] Preferably, a driving rod is provided at one end of the driving gear, and a torsion block is provided through the through hole by the driving rod.

[0010] Advantageous Effects

[0011] One or more of the above technical solutions in the base of a thermal overload relay which is convenient to install provided by the embodiment of the utility model at least have the following technical effects:

[0012] With the above technical solution of the present utility model, by rotating the driving gear, the transmission gear drives the lead screw to rotate, causing the slider to slide along the chute. The slider drives the movable buckle to move towards the fixed buckle, so that the relay base can be installed on the guide rail. The operation is simple and convenient. Moreover, by adjusting the distance between the movable buckle and the fixed buckle, it is possible to adapt to installation guide rails of different widths and sizes, thereby improving the installation applicability.

[0021] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] As Figures 1-4 shown, it is a schematic structural view of a heat overload relay base that is easy to install according to a preferred embodiment of the present utility model;

[0023] In this embodiment, it includes a relay base 1. A card slot 2 is provided at the center of the bottom of the relay base 1. An active buckle 3 is movably provided at the front of the card slot 2. The active buckle 3 can move along the length direction of the card slot 2. A fixed buckle 4 is integrally fixed at the rear of the card slot 2. An inner cavity 5 is provided at the front of the relay base 1. A driving gear 6 is rotatably provided inside the inner cavity 5. Transmission gears 7 are meshed on both sides of the driving gear 6. The rotation of the driving gear 6 drives the two transmission gears 7 to rotate simultaneously. Two parallel chutes 8 are provided on both sides of the surface of the card slot 2. The chutes 8 are arranged along the length direction of the card slot 2. The inner cavity 5 communicates with the chutes 8. Lead screws 9 are rotatably provided in the chutes 8. The lead screws 9 are fixedly connected to the transmission gears 7 in a snap-fit manner. The rotation of the transmission gears 7 drives the lead screws 9 to rotate coaxially. Sliders 10 are integrally fixed on both sides of the top of the active buckle 3. The sliders 10 are slidably arranged in the chutes 8 and are screwed to the lead screws 9. When the lead screws 9 rotate, due to the thread action, the sliders 10 can slide along the chutes 8, thereby causing the active buckle 3 to move.

[0024] In this embodiment, a cover plate 11 is provided at the front of the inner cavity 5 to protect the components inside the inner cavity 5 through the cover plate 11. A through hole is provided in the middle of the surface of the cover plate 11. The through hole is a circular hole.

[0025] In this embodiment, a driving rod 12 is provided at one end of the driving gear 6. The driving rod 12 passes through the through hole and is provided with a torsion block 13. During use, by turning the torsion block 13, the driving rod 12 rotates to drive the driving gear 6 to rotate together. The torsion block 13 is more convenient for the operator to operate.

[0026] The principle of the present utility model:

[0027] By turning the torsion block 12, the driving rod drives the driving gear to rotate. The driving gear 6 drives the transmission gear 7 and the lead screw 9 to rotate. Under the action of the screw connection between the lead screw 9 and the slider 10, the slider 10 slides along the chute 8. The slider 10 drives the movable buckle 3 to move towards the fixed buckle 4, so that the relay base 1 can be installed on the guide rail. The operation is simple and convenient. Moreover, by rotating the driving gear 6 forward and backward, the distance between the movable buckle 3 and the fixed buckle 4 can be adjusted, so that it can be applied to installation guide rails of different width dimensions, and the installation applicability is improved.
