Description
Technical field
The invention belongs to electronic control device technical field more particularly to easy-to-dismount relays.
Background technique
Relay is a kind of electric control device, is when the variation of input quantity reaches prescribed requirement, in electrical output circuit
In make controlled volume that a kind of electric appliance of scheduled Spline smoothing occur.It has control system (also known as input circuit) and by control
Interactive relationship between system (also known as output loop).It is usually applied in automation control circuit, it is actually with small electricity
Flow away one kind " automatic switch " of control high current running.Therefore play automatic adjustment, safeguard protection, conversion circuit in circuit etc.
Effect.
Existing relay includes shell and bottom plate, and shell generally has screw to connect or adopt with the connection type of bottom plate
Shell is fixedly connected with bottom plate with sealant, is connected shell with bottom plate using sealant, is broken down inside relay
When needing repairing, shell and bottom plate cannot be dismantled, and cause to repair；And shell is used to connect with bottom plate using screw, it dismantles
Shell and bottom plate are more troublesome, and are not fully sealed between shell and bottom plate, will receive ambient atmos in use
Or the influence of water, influence the performance of relay.
Summary of the invention
The purpose of the present invention is providing a kind of easy-to-dismount relay, can quickly dismantle shell and the bottom of relay
Plate, convenient for being overhauled to relay.
In order to achieve the above object, base case of the invention are as follows: easy-to-dismount relay, including shell, bottom plate and
It is fixed on the relay main body structure of plate upper surface, the shell is fastened on the top of bottom plate；The left and right of the sidewall of the bottom plate
Two sides are provided with sliding slot, and strip is slidably connected in sliding slot, and the first spring is connected between strip and sliding slot；The following table of the strip
Face is connected with pull rod, is provided on the bottom plate for the movable through slot of pull rod；It is equipped with convex block at left and right sides of the outer casing underpart,
The cavity engaged with strip is provided on convex block；Sliding block is slidably connected in the cavity, and second is connected between sliding block and cavity
Spring；The position of the shell and contacts baseplate is equipped with air bag, and tracheae is connected between air bag and cavity.
The working principle of this base case is: the shell of this relay is detachably connected with bottom plate, when needing shell
When assembling with bottom plate, bottom plate is placed on to the lower section of shell, pulls pull rod, strip overcomes the elastic force of spring to be completely disposed at sliding slot
It is interior, keep strip opposite with cavity, then releasing lever, a part of strip is put in cavity.The process of cavity is protruded into strip
In, strip and shoe contact, strip apply active force to sliding block, so that sliding block is slided along cavity, sliding block compresses tension spring.Work as card
When the active force that the active force that item applies sliding block and tension spring apply sliding block is equal, sliding block stop motion keeps relative stability
State.When sliding block is slided along cavity, sliding block compresses the gas in cavity, and the gas in cavity is transferred to air bag by tracheae
In, the air bag of air bag expansion, expansion blocks the gap between bottom plate and shell, prevents extraneous moisture, gas from entering relay
In device.
The beneficial effect of this base case is:
1, the shell of relay and bottom plate are by being connected together as an entirety, when needing to repair relay,
Active force is applied to pull rod, retracting strip can separate shell with bottom plate in sliding slot, dismantle very convenient, fast.
2, when needing to assemble on shell and bottom plate, engage strip with cavity, it is recessed during assembling relay
Intracavitary gas is compressed, and gas is transferred in air bag by tracheae, and air bag expansion, the air bag of expansion will be between bottom plate and shell
Gap blocking, enhance the sealing performance of relay, effectively prevent extraneous moisture, gas to enter relay, influence relay
The performance of device.
Further, two tracheaes are connected between the air bag and cavity, a tracheae is equipped with when air pressure increases in cavity
The one-way exhaust valve that can be automatically opened when big, another tracheae are equipped with and can automatically open when air pressure is reduced in cavity
Breather cheek valve.When sliding block compresses the gas in cavity, the air pressure in cavity increases, and one-way exhaust valve is opened, the gas in cavity
Body is transferred in air bag by tracheae；When sliding block sets back under the promotion of second spring, the volume of cavity increases, in cavity
Air pressure reduce, breather cheek valve is opened, and the gas in air bag is returned in cavity by tracheae.
Further, the bottom plate is equipped with the groove cooperated with air bag.Groove and air bag cooperate, and the setting of groove is on the one hand
Play the role of to air bag fixed, on the other hand air bag is come into full contact with groove, facilitates the leakproofness for enhancing relay.
Further, the position of the convex block and contacts baseplate is equipped with elastic cushion.The setting of elastic cushion helps to enhance bottom plate
Leakproofness.
Further, the length of the through slot is greater than the length of pull rod, and the pull rod is hinged on strip.When do not need using
When pull rod, pull rod can be accommodated in through slot, pull rod is avoided to interfere the normal use of relay.
Further, the position that the sliding block is contacted with cavity is equipped with gasket.The setting of gasket enhances the close of cavity
Feng Xing avoids the gas in cavity from being transferred to the external world.
