Description

Technical Field

[0001] The utility model relates to a combined relay with convenient capacity expansion, belonging to the technical field of combined relays. Background Art

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches the specified requirement. It has an interactive relationship between the control system and the controlled system and is usually used in automated control circuits. It is actually a switch that uses a small current to control the operation of a large current.

[0003] According to the authorized patent CN202320825644.9, the distance between the front limit frame and the rear limit frame can be adjusted according to the size of the relay structure, so as to improve the adaptability of the relay structure and facilitate the limited installation of the relay structure. The quick-release installation of the snap-fit ​​assembly and the plug-in assembly can achieve the purpose of expansion while ensuring the stability between the relay structures.

[0004] However, during installation, the push positioning process cannot be performed according to the number of internal components, which will result in a lot of time being wasted when expanding the capacity. At the same time, when the number of components is small, relying solely on the elasticity of the spring itself will cause the components to become loose. In addition, the components inside the relay are prone to falling off during installation because there is no protective mechanism on the outside. Utility Model Content

[0005] The purpose of the present invention is to provide a combined relay that is easy to expand. The present invention has a simple structure and is easy to use. It can quickly expand the capacity of the relay and protect the components inside the relay to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The cam is fixedly connected to the top of the relay housing, and the cam is fixedly connected to the top of the relay housing, and the cam is fixedly connected to the top of the relay housing.

[0008] Furthermore, a protective plate is fixedly connected to the outer side of the positioning plate, a hidden groove is provided inside the protective plate, an extension plate is slidably connected inside the hidden groove, a positioning hole is provided inside the extension plate, a rubber ring is fixedly connected to the top of the protective plate, a connecting rod is movably connected inside the rubber ring, and an extrusion cover is fixedly connected to the top of the connecting rod.

[0009] Furthermore, the unit components are evenly distributed inside the relay housing, and the stabilizing plate and the fixing plate are in corresponding positions.

[0010] Furthermore, the reset spring is symmetrically distributed between the stabilizing plate and the positioning plate, the sliding rod is slidably connected to the inside of the moving groove, and the positioning plate is slidably connected to the inside of the relay housing.

[0011] Furthermore, the push rod is slidably connected to the inside of the sliding groove, and the push rod crosses the inside of the stabilizing plate, while the end of the push rod away from the moving block is located on the outside of the positioning plate.

[0012] Furthermore, the protection plate and the extension plate are located outside the unit components, and the positioning holes are evenly distributed inside the extension plate.

[0013] Furthermore, the clamping rod passes through the inner wall of the protective plate, and the bottom of the clamping rod is located inside the positioning hole.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model sets up a relay housing, and the unit components are installed inside the relay housing. When the device needs to be expanded, the unit components are first installed inside the relay housing. At this time, the moving block slides on the top of the connecting plate, so that the moving block drives the push rod to move. The movement of the push rod pushes the positioning plate outside the reset spring, so that the positioning plate moves inside the relay housing under the action of the sliding rod. At this time, the positioning plate will position the unit components. When the unit components are tightly connected, the screw is rotated and moved inside the threaded tube by turning the screw. At this time, the screw will move to the outside of the connecting plate, thereby limiting the moving block on the top of the connecting plate, achieving the effect of ensuring that the unit components inside the relay housing can be stably connected while expanding the capacity.

[0016] (2) The utility model is provided with a relay housing, and unit components are installed inside the relay housing. After the positioning plate positions the unit components, the protective plate is fixedly connected to the outer side of the positioning plate, so the protective plate can protect the unit components. When the number of unit components is large, the clamping rod is first moved upward inside the rubber ring, so that the bottom of the clamping rod is moved out of the positioning hole inside the extension plate. At this time, the extension plate is extended by sliding, so that it maintains the same length as the unit components. At this time, the bottom of the clamping rod is inserted into the interior of the positioning hole, so that the extension plate maintains stability, thereby achieving the effect of protecting the unit components.

[0027] Specifically, such as Figure 1 As shown, the unit components 2 are evenly distributed inside the relay housing 1, the stabilizing plate 4 and the fixing plate 5 are in corresponding positions, the reset spring 6 is symmetrically distributed between the stabilizing plate 4 and the positioning plate 7, the slide rod 8 is slidably connected to the inside of the moving groove 9, and the positioning plate 7 is slidably connected to the inside of the relay housing 1, the push rod 12 is slidably connected to the inside of the slide groove 13, and the push rod 12 crosses the inside of the stabilizing plate 4, and at the same time, the end of the push rod 12 away from the moving block 11 is located on the outside of the positioning plate 7.

[0028] In this embodiment: a relay housing 1 is provided, and the unit component 2 is installed inside the relay housing 1. When the device needs to be expanded, the unit component 2 is first installed inside the relay housing 1. At this time, the moving block 11 slides on the top of the connecting plate 10, so that the moving block 11 drives the pushing rod 12 to move. The movement of the pushing rod 12 pushes the positioning plate 7 on the outside of the reset spring 6, so that the positioning plate 7 moves inside the relay housing 1 under the action of the sliding rod 8. At this time, the positioning plate 7 will position the unit component 2. When the unit component 2 is tightly connected, the screw 16 is rotated and moved inside the threaded tube 15. At this time, the screw 16 will move to the outside of the connecting plate 10, thereby limiting the moving block 11 on the top of the connecting plate 10, achieving the effect of ensuring that the unit component 2 inside the relay housing 1 can be stably connected while expanding the capacity.

When the number of unit components 2 is large, the clamping rod 22 is first moved upward inside the rubber ring 21, so that the bottom of the clamping rod 22 is moved out from the positioning hole 20 inside the extension plate 19. At this time, the extension plate 19 is extended by sliding the extension plate 19 so that it maintains the same length as the unit component 2. At this time, the bottom of the clamping rod 22 is inserted into the inside of the positioning hole 20, so that the extension plate 19 maintains stability, thereby achieving the effect of protecting the unit component 2.
