Description

Technical Field

[0001] The present invention relates to the technical field of relays, in particular to a pulse relay. Background Art

[0002] Pulse relays can realize remote control circuits: multi-point control through pulse commands. Pulse relays are used to control resistive load circuits (such as incandescent lamps, low-voltage halogen lamps, convection heaters) and inductive load circuits (such as fluorescent tubes, discharge lamps). When teachers introduce relays to students in class, they need to show them the relays.

[0003] However, when the teacher is explaining the knowledge of pulse relays to students, the teacher needs to hold the relay in his hand and adjust the angle of the relay to explain the knowledge of different parts of the relay. At the same time, since there are wiring contacts at the bottom of the relay, chalk dust is easy to adhere to the wiring contacts at the bottom of the relay during the process of explaining the knowledge about relays in the classroom. If the wiring contacts at the bottom of the relay are not cleaned, the conductive performance of the wiring contacts when connected to electricity will be affected, that is, the power-on experiment of the relay will be affected.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-9 In an embodiment of the present invention, a pulse relay includes a relay body 1 and a moving plate 2;

[0039] The front and rear side walls of the relay body 1 are symmetrically fixedly connected with side plates 3, the movable plate 2 is locked on the side plates 3, the movable plate 2 is fixedly connected with a connecting plate 4, the connecting plate 4 is rotatably connected with a roller 5, a movable block 6 is movably connected inside the roller 5, a movable rod 7 is elastically connected to the circumferential outer wall of the movable block 6, the movable rod 7 is connected to the mounting box 8, a cylindrical block 9 is rotatably connected inside the mounting box 8, and a cleaning plate 13 is connected to the cylindrical block 9;

[0040] A carrying plate 46 is fixedly connected to the side wall of the relay body 1, a first clamping plate 47 is slidably connected to the side wall of the carrying plate 46, a second clamping plate 48 is elastically connected to the upper end of the first clamping plate 47, an L-shaped rod 49 is fixedly connected to the upper part of the movable plate 2, a cross plate 50 is fixedly connected to the L-shaped rod 49, an L-shaped plate 51 is fixedly connected to the side wall of the cross plate 50, a trapezoidal block 52 is fixedly connected to the L-shaped plate 51, a push rod 53 is fixedly connected to the lower surface of the cross plate 50, and a pressure plate 54 is rotatably connected to the lower end of the push rod 53;

[0041] A third spring 55 is fixedly connected between the first clamping plate 47 and the second clamping plate 48;

[0042] A sliding groove 56 is formed on the side wall of the bearing plate 46, and the bottom end of the first clamping plate 47 is slidably connected in the sliding groove 56;

[0043] The pressure plate 54 is rotatably connected to the side wall of the relay body 1 through the rotating rod 57;

[0044] One end of the first clamping plate 47 is fixedly connected to a fourth spring 58 , and the fourth spring 58 is fixedly connected to a side wall of the sliding groove 56 .

[0045] Before conducting a power-on test on the relay body 1, the staff manually pushes the second clamping plate 48 upward to move the second clamping plate 48 upward, then places the wires electrically connected to the relay body 1 between the first clamping plate 47 and the second clamping plate 48, and manually loosens the second clamping plate 48. Due to the elastic recovery effect of the third spring 55, the second clamping plate 48 moves relative to the first clamping plate 47, thereby clamping the wires through the first clamping plate 47 and the second clamping plate 48.

[0046] When it is necessary to conduct an electrical test on the wires and the relay body 1, the second hydraulic rod 44 operates to move the movable plate 2 upward. Since the movable plate 2 is fixedly connected to the transverse plate 50 via the L-shaped rod 49, and the transverse plate 50 is fixedly connected to the trapezoidal block 52 via the L-shaped plate 51, the trapezoidal block 52 is moved upward by the transverse plate 50 and the L-shaped plate 51 during the upward movement of the movable plate 2. During the upward movement of the trapezoidal block 52, the trapezoidal block 52 is not in contact with the second clamping plate 48. At the same time, due to the elastic restoring effect of the fourth spring 58, the second clamping plate 48 is moved along the sliding groove 56 toward the contact point of the relay body 1 (before the trapezoidal block 52 moves upward, the oblique side of the trapezoidal block 52 contacts the second clamping plate 48, and the trapezoidal block 52 prevents the second clamping plate 48 from being moved upward). The plate 48 moves, and at this time the fourth spring 58 is in an extended and energy-accumulating state). When the second clamping plate 48 moves along the sliding groove 56 toward the contact of the relay body 1, the terminal of the wire moves to the bottom of the pressure plate 54 and contacts the contact of the relay body 1. Then the second hydraulic rod 44 continues to work to realize the upward movement of the cross plate 51. Since the lower surface of the cross plate 51 is fixedly connected to the push rod 53, during the upward movement of the cross plate 51, one end of the pressure plate 54 is pulled upward by the push rod 53. Since the pressure plate 54 is rotatably connected to the relay body 1 through the rotating rod 57, the other end of the pressure plate 54 moves downward until the terminal of the wire is pressed against the contact of the relay body 1 by the pressure plate 54, thereby realizing the connection between the wire and the relay body 1, which is convenient for power-on testing.

[0047] When it is not necessary to conduct an electrical test on the relay body 1, or when it is necessary to move the relay body 1 for structural explanation and analysis, the second hydraulic rod 44 works to realize the downward movement of the movable plate 2. During the downward movement of the movable plate 2, one end of the pressing plate 54 is moved downward by the push rod 52. Since the pressing plate 54 is connected to the relay body 1 by rotation through the rotating rod 57, the other end of the pressing plate 54 moves upward. During the upward movement of the other end of the pressing plate 54, the pressing plate 54 releases the wires. At the same time, during the downward movement of the movable plate 2, since the movable plate 2 is fixedly connected to the horizontal plate 50 by the L-shaped rod 49, the horizontal plate 50 is fixed to the trapezoidal block 52 by the L-shaped plate 51. The movable plate 2 is fixedly connected, so during the downward movement of the movable plate 2, the trapezoidal block 52 is moved downward by the transverse plate 50 and the L-shaped plate 51. During the downward movement of the trapezoidal block 52, the second clamping plate 48 is pushed by the oblique side of the trapezoidal block 52, so that the second clamping plate 48 moves outward along the sliding groove 56. Since the first clamping plate 47 and the second clamping plate 48 clamp the wires, the wires are moved outward. During the outward movement of the wires, the wires are separated from the contacts of the relay body 1, thereby disconnecting the power to the relay body 1. Therefore, the relay body 1 can be moved for easy display in different positions.

[0048] Therefore, this structure achieves the purpose of quickly wiring the relay body, making it easy to explain the structure and working principle of the relay to students when the power is on or off.

[0049] A groove is provided on the movable plate 2 , in which an intermediate block 20 is fixedly connected. Both ends of the intermediate block 20 are connected to a T-shaped rod 21 , and one end of the T-shaped rod 21 passes through the side wall of the groove and is inserted into the side plate 3 .

[0050] Both ends of the middle block 20 are fixedly connected to a first hydraulic rod 22, and the first hydraulic rod 22 is fixedly connected to the T-shaped rod 21;

[0051] A first socket 23 is provided on the side panel 3, and the first socket 23 cooperates with the T-shaped rod 21. When the position of the movable plate 2 needs to be adjusted, the staff manually pushes the T-shaped rod 21 to move the T-shaped rod 21. When one end of the T-shaped rod 21 is detached from the side panel 3, the movable plate 2 can be manually moved. After the movable plate 2 moves, the T-shaped rod 21 is manually released. Due to the action of the first hydraulic rod 22, the T-shaped rod 21 is moved. When one end of the T-shaped rod 21 is inserted into the side panel 3, the movable plate 2 is locked.

[0052] A accommodating cavity 24 is provided in the side plate 3, and a second gear 25 is rotatably connected in the accommodating cavity 24. The two ends of the second gear 25 are respectively engaged with a first rack 26 and a second rack 27. One end of the first rack 26 passes through the side wall of the accommodating cavity 24 and is fixedly connected to the movable plate 2. The second rack 27 is slidably connected to the side wall of the accommodating cavity 24. A connecting rod 28 is fixedly connected to the second rack 27. One end of the connecting rod 28 passes through the side wall of the accommodating cavity 24 and is fixedly connected to the support block 29. When the movable plate 2 moves downward, the first rack 26 moves downward. Since the first rack 26 and the second rack 27 are both connected to the second rack The gear 25 is engaged, so the second gear 25 rotates during the movement of the first rack 26, and the second rack 27 moves upward during the rotation of the second gear 25, thereby realizing the upward movement of the support block 29 through the connecting rod 28; the first rack 26 moves upward during the upward movement of the movable plate 2, and since the first rack 26 and the second rack 27 are both engaged with the second gear 25, the second gear 25 rotates during the movement of the first rack 26, and the second rack 27 moves downward during the rotation of the second gear 25, thereby realizing the downward movement of the support block 29 through the connecting rod 28.

[0053] A crossbar 30 is fixedly connected to the first rack 26. A strip-shaped hole 31 is opened on the side wall of the accommodating cavity 24. One end of the crossbar 30 passes through the side wall of the strip-shaped hole 31 and is fixedly connected to the movable plate 2.

[0054] A sliding groove 32 is provided on the side wall of the accommodating cavity 24 , and a slider 33 is slidably connected in the sliding groove 32 . The slider 33 is fixedly connected to the second rack 27 . The arrangement of the sliding groove 32 and the slider 33 facilitates the sliding of the second rack 27 in the accommodating cavity 24 .

[0055] The roller 5 is rotatably connected to the connecting plate 4 via the rotating shaft 34 , and the rotating shaft 34 facilitates the rotation of the roller 5 relative to the connecting plate 4 .

[0056] The moving block 6 is provided with a receiving groove, in which a second spring 35 is fixedly connected. The second spring 35 is fixedly connected to the moving rod 7. Since the second spring 35 facilitates the elastic connection of the moving rod 7, it also facilitates the movement of the moving rod 7.

[0057] A push rod 36 is fixedly connected between the moving rods 7, and a second insertion rod 37 is fixedly connected to one of the push rods 36. A second hole 38 is provided on the inner wall of the drum 5, and the second hole 38 cooperates with the second insertion rod 37. The staff manually pushes the push rod 36, and the second insertion rod 37 is driven to move by the push rod 36. When one end of the second insertion rod 37 is disengaged from the second hole 38, it is convenient to manually move the moving block 6, thereby adjusting the position of the moving block 6.

[0058] The cylindrical block 9 is connected to the cleaning plate 13 via fixing bolts 39 . The setting of the fixing bolts 39 facilitates the installation and removal of the cleaning plate 13 on the cylindrical block 9 .

[0059] When the present invention is in use, before conducting a power-on test on the relay body 1, the staff manually pushes the second clamping plate 48 upward to move the second clamping plate 48 upward, and then places the wires electrically connected to the relay body 1 between the first clamping plate 47 and the second clamping plate 48, and manually loosens the second clamping plate 48. Due to the elastic recovery effect of the third spring 55, the second clamping plate 48 moves relative to the first clamping plate 47, thereby clamping the wires through the first clamping plate 47 and the second clamping plate 48.

[0060] When it is necessary to conduct an electrical test on the wires and the relay body 1, the second hydraulic rod 44 operates to move the movable plate 2 upward. Since the movable plate 2 is fixedly connected to the transverse plate 50 via the L-shaped rod 49, and the transverse plate 50 is fixedly connected to the trapezoidal block 52 via the L-shaped plate 51, the trapezoidal block 52 is moved upward by the transverse plate 50 and the L-shaped plate 51 during the upward movement of the movable plate 2. During the upward movement of the trapezoidal block 52, the trapezoidal block 52 is not in contact with the second clamping plate 48. At the same time, due to the elastic restoring effect of the fourth spring 58, the second clamping plate 48 is moved along the sliding groove 56 toward the contact point of the relay body 1 (before the trapezoidal block 52 moves upward, the oblique side of the trapezoidal block 52 contacts the second clamping plate 48, and the trapezoidal block 52 prevents the second clamping plate 48 from being moved upward). The plate 48 moves, and at this time the fourth spring 58 is in an extended and energy-accumulating state). When the second clamping plate 48 moves along the sliding groove 56 toward the contact of the relay body 1, the terminal of the wire moves to the bottom of the pressure plate 54 and contacts the contact of the relay body 1. Then the second hydraulic rod 44 continues to work to realize the upward movement of the cross plate 51. Since the lower surface of the cross plate 51 is fixedly connected to the push rod 53, during the upward movement of the cross plate 51, one end of the pressure plate 54 is pulled upward by the push rod 53. Since the pressure plate 54 is rotatably connected to the relay body 1 through the rotating rod 57, the other end of the pressure plate 54 moves downward until the terminal of the wire is pressed against the contact of the relay body 1 by the pressure plate 54, thereby realizing the connection between the wire and the relay body 1, which is convenient for power-on testing.

[0061] When it is not necessary to conduct an electrical test on the relay body 1, or when it is necessary to move the relay body 1 for structural explanation and analysis, the second hydraulic rod 44 works to realize the downward movement of the movable plate 2. During the downward movement of the movable plate 2, one end of the pressing plate 54 is moved downward by the push rod 52. Since the pressing plate 54 is connected to the relay body 1 by rotation through the rotating rod 57, the other end of the pressing plate 54 moves upward. During the upward movement of the other end of the pressing plate 54, the pressing plate 54 releases the wires. At the same time, during the downward movement of the movable plate 2, since the movable plate 2 is fixedly connected to the horizontal plate 50 by the L-shaped rod 49, the horizontal plate 50 is fixed to the trapezoidal block 52 by the L-shaped plate 51. The movable plate 2 is fixedly connected, so during the downward movement of the movable plate 2, the trapezoidal block 52 is moved downward by the transverse plate 50 and the L-shaped plate 51. During the downward movement of the trapezoidal block 52, the second clamping plate 48 is pushed by the oblique side of the trapezoidal block 52, so that the second clamping plate 48 moves outward along the sliding groove 56. Since the first clamping plate 47 and the second clamping plate 48 clamp the wires, the wires are moved outward. During the outward movement of the wires, the wires are separated from the contacts of the relay body 1, thereby disconnecting the power to the relay body 1. Therefore, the relay body 1 can be moved for easy display in different positions.

[0062] Therefore, this structure achieves the purpose of quickly wiring the relay body, making it easy to explain the structure and working principle of the relay to students when the power is on or off.

[0063] When the second spring 35 is released, the second rod 37 is moved to the outside of the drum 5, and the staff manually pushes the push rod 36, which drives the second insertion rod 37 to move. When one end of the second insertion rod 37 is detached from the drum 5, the moving block 6 is manually pulled to move the moving block 6, so that one end of the moving block 6 moves to the outside of the drum 5. Then, the push rod 36 is manually released, and the push rod 36 is moved due to the elastic force of the second spring 35. During the movement of the push rod 36, the second insertion rod 37 is moved. When one end of the second insertion rod 37 is inserted on the drum 5, the moving block 6 is fixed. The staff moves and locks the moving block 6 to the outside of the drum 5, that is, the cleaning cotton 12 on the moving block 6 is also moved to the outside of the drum 5, and under the elastic recovery action of the second spring 35, the cleaning cotton 12 is attached to the bottom of the relay body 1, thereby driving the moving block 6 to rotate when the drum 5 rotates. During the rotation of the moving block 6, and because the cleaning cotton 12 is attached to the bottom of the relay body 1, the relay body 1 is cleaned during the rotation of the cleaning cotton 12.

[0064] When the relay body 1 needs to be moved and displayed on the podium, the first hydraulic rod 22 works to move the T-shaped rod 21. When one end of the T-shaped rod 21 is detached from the side plate 3, the second hydraulic rod 44 is fixedly connected to the side wall of the relay body 1. The second hydraulic rod 44 works to move the movable plate 2 downward. The first hydraulic rod 22 acts to insert one end of the T-shaped rod 21 on the side plate 3, thereby locking the movable plate 2.

[0065] During the downward movement of the movable plate 2, the first rack 26 moves downward. Since the first rack 26 and the second rack 27 are both engaged with the second gear 25, the second gear 25 rotates during the movement of the first rack 26, and the second rack 27 moves upward during the rotation of the second gear 25, thereby realizing the upward movement of the support block 29 through the connecting rod 28, thereby realizing the support effect on the relay body 1 through the support block 29, and at the same time, realizing the positioning of the roller 5 on the podium during the downward movement of the movable plate 2.

[0066] A driving motor 45 is fixedly connected to the connecting plate 4 , and a driving shaft of the driving motor 45 is fixedly connected to the roller 5 therein.

[0067] The driving motor 45 works to realize the rotation of the roller 5, and the relay body 1 is moved during the rotation of the roller 5, thereby adjusting the position of the relay body 1 on the podium. At the same time, since the cleaning cotton 12 is in contact with the bottom of the relay body 1, the cleaning plate 13 is rotated during the rolling of the roller 5. Since the moving block 6 moves and is locked to the outside of the roller 5, the cleaning cotton 12 on the moving block 6 is also moved to the outside of the roller 5, and under the elastic recovery action of the second spring 35, the cleaning cotton 12 is attached to the bottom of the relay body 1, thereby driving the moving block 6 to rotate when the roller 5 rotates. During the rotation of the relay body 1, the cleaning cotton 12 is attached to the bottom of the relay body 1, so the relay body 1 is cleaned during the rotation of the cleaning cotton 12. When the cleaning cotton 12 acts on the relay body 1, it is easy to clean the chalk dust on the bottom of the relay body 1, thereby preventing a large amount of chalk dust from accumulating on the bottom of the relay body 1. Since the bottom of the relay body 1 is fixedly connected to the wiring contacts, if there is a lot of chalk dust on the bottom of the relay body 1, the chalk dust will adhere to the wiring contacts, which will affect the conductive performance when the staff connects the wiring contacts to electricity, that is, affect the operation of the relay body 1.

[0068] The term "fixed connection" as used in the present invention means that the two interconnected parts are fixed together, generally by welding, screws or gluing; and "rotational connection" means that the two parts are connected together and can move relative to each other.

[0069] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
