Description

[0002] In the prior art, most elevator switches use a single-wheel automatic recovery travel switch, which mainly relies on the expansion and contraction performance of a single reset spring to separate the moving contact piece from the static contact piece to reset the switch.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings of the utility model specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In a specific embodiment of the present invention, Figure 1-7 As shown, a miniaturized and long-life elevator switch comprises a housing 1 and a first rotating seat 2 arranged outside the housing 1, and a second rotating seat 3, a mounting seat 4, a moving contact piece 5 and a stationary contact piece 6 arranged inside the housing 1. One end of the first rotating seat 2 extends outward to form a limiting portion 21 for limiting the rotation range of the first rotating seat 2. Two guide wheels 14 are arranged on the upper part of the first rotating seat 2, and the lower part is sleeved on the outer side of the housing 1. A connecting piece 7 is inserted into the second rotating seat 3, and both ends of the connecting piece 7 extend out of the housing 1 and are connected to the first rotating seat 2.

[0037] The mounting seat 4 is located below the second rotating seat 3, the stationary contact piece 6 is fixed at one end of the mounting seat 4, and the moving contact piece 5 is fixed at the other end of the mounting seat 4, and its contact end passes through the bottom of the second rotating seat 3 and then extends out; an elastic member is also provided in the housing 1, and the elastic member is used to assist the moving contact piece 5 to separate from the stationary contact piece 6; in this embodiment, the stationary contact piece 6 is C-shaped;

[0038] When the baffle 100 of the elevator contacts or separates from the guide wheel 14, the first rotating seat 2 and the second rotating seat 3 are driven to rotate, so that the moving contact piece 5 contacts or separates from the static contact piece 6.

[0039] The elastic member is one or both of a torsion spring 8 and a tension spring 9. Figure 2 As shown, the elastic member in this embodiment is a torsion spring 8 and a tension spring 9. Of course, in other embodiments, the elastic member can be designed as a torsion spring 8 or a tension spring 9 alone.

[0040] Specifically, Figure 2 As shown, an annular cavity 31 is provided in the second rotating seat 3, and the annular cavity 31 is located on the outside of the connecting member 7. A first opening 32 and a second opening 33 communicating with the annular cavity 31 are provided on both sides of the second rotating seat 3, respectively. An arc transition surface 312 is provided between the inner wall of the first opening 32 and the inner wall of the annular cavity 31. The torsion spring 8 is arranged in the annular cavity 31, and one end thereof extends out of the second opening 33, and the other movable end 81 extends into or slides out of the first opening 32 under the rotation of the second rotating seat 3; Figure 2 As shown, in this state, the moving and stationary pieces are in contact with the stationary contact piece, the switch is energized, and the movable end 81 of the torsion spring 8 slides from the first opening 32 along the arc transition surface 312 into the annular cavity 31, and abuts against the inner wall of the annular cavity 31. The design of the torsion spring can provide a certain torsional pulling force for the separation of the moving contact piece and the stationary contact piece, thereby improving the service life of the switch; and the design of the arc transition surface here can make the movable end of the torsion spring slide more smoothly, thereby improving the service life of the torsion spring, and indirectly improving the service life of the switch.

[0041] In addition, in this embodiment, the tension spring 9 is installed between the second rotating seat 3 and the mounting seat 4 through the mounting assembly, and the second rotating seat 3 is driven to rotate by the reset performance of the tension spring 9, providing a certain pulling force for the separation of the moving contact piece 5 and the stationary contact piece 6, thereby improving the service life of the switch;

[0042] The mounting assembly includes two protective seats 18 respectively arranged on the second rotating seat 3 and the mounting seat 4, and spring columns 19 are arranged in the two protective seats 18. A cavity for accommodating the end of the tension spring 9 is arranged between the spring column 19 and the protective seat 18. The tension spring 9 is sleeved on the spring column 19 and its end is placed in the cavity and fixed thereto; here, through the design of the protective seat, the spring column and the cavity, it is possible to prevent the tension spring from detaching from the spring column, thereby improving the service life of the tension spring.

[0043] like Figure 2 and Figure 4 , the mounting seat 4 is provided with two mounting parts 41 distributed on the left and right, and the first contact seat 10 and the second contact seat 11 are respectively installed in the two mounting parts 41. The upper part of the first contact seat 10 is sleeved with a moving contact piece 5, and the upper end thereof is provided with a rivet for fixing the moving contact piece 5, and the lower end is threadedly connected with a first wiring screw 12, and a copper sheet 17 is provided between the first contact seat 10 and the first wiring screw 12, and the lower end of the second contact seat 11 passes through the bottom of the static contact piece 6 and is locked by the second wiring screw 13, and a conductive wire is connected between the second wiring screw 13 and the first wiring screw 12, and the wiring end of the conductive wire extends out of the housing 1. In this embodiment, the material of the first contact seat and the second contact seat is copper, and when the contact end of the moving contact piece 5 contacts the static contact piece 6, a closed circuit can be formed inside the switch. In this embodiment, the contact end of the moving contact piece is designed with two contacts, and a double contact form is adopted to make it effectively contact with the static contact piece.

[0044] In this embodiment, a first gasket 15 is provided between the first connecting screw 12 and the copper sheet 17, and a second gasket 16 is provided between the second connecting screw 13 and the stationary contact piece 6. Figure 7 As shown, the first gasket 15 and the second gasket 16 both adopt an outwardly expanded concave structure, and are provided with a convex surface 156 therein, and the convex surface 156 is fitted with the bottom end of the first contact seat 10 or the second contact seat 11. Specifically, the first wiring screw 12 is threadedly connected to the first contact seat 10, the upper end of the first wiring screw 12 passes through the first gasket 15 and its top surface is fitted with the copper sheet 17, and the upper end of the second wiring screw 13 passes through the second gasket 16 and its top surface is fitted with the static contact sheet 6. Through the design of the first gasket and the second gasket, the stability of the connection between the first wiring screw and the first contact seat, and the second wiring screw and the second contact seat can be strengthened, and the stability when power is turned on can be indirectly strengthened.

[0045] In this embodiment, a limit baffle 42 is provided on the mounting seat 4. The limit baffle 42 has a pair and is located on both sides of the two mounting portions 41, and is used to limit the shaking of the moving contact piece 5. Through the design of the limit baffle, the shaking or separation of the moving contact piece 5 during the operation of the switch can be avoided, thereby improving the stability of the moving contact piece 5 during the operation of the switch.

[0046] In this embodiment, the connecting member 7 is a rotating shaft with a plane.

[0047] In this embodiment, Figure 5 As shown, the housing 1 includes an upper housing 111 and a lower housing 112. A protrusion is provided on the upper portion of the upper housing 111. The first rotating seat 2 is sleeved on the outer side of the protrusion. A mounting hole 1111 for passing the connecting member 7 is provided on the protrusion. A mounting hole 1112 is provided on the lower portion of the upper housing 111. A plurality of through holes 44 corresponding to the mounting hole 1112 are provided on the mounting seat 4. Fasteners for fixing the upper housing 111 and the mounting seat 4 are installed in the through holes 44 and the mounting hole 1112. In this embodiment, the fastener is a connecting shaft that can fix the mounting seat 4.

[0048] like Figure 6 As shown, the inner wall of the lower shell 112 is provided with a plurality of slots 1120, and the outer side of the mounting seat 4 is provided with a plurality of blocks 43 that cooperate with the slots 1120; through the design of the slots and the blocks, the installation between the mounting seat and the lower shell can be more convenient, and through the design of the through holes, the upper shell can be connected to the mounting seat, making the internal installation of the switch more convenient.

[0049] Here, if Figure 5 As shown, an assembly hole 1113 for fixing the switch is provided on one side wall of the upper shell 111, making the installation of the switch more convenient, and a wire hole 1121 for the conductive wire to pass through is provided on the side wall of the lower shell 112; the top inner wall of the upper shell can play a certain limiting role in the rotation of the second rotating seat, avoiding the torsion spring from detaching from the annular cavity of the second rotating seat due to excessive rotation angle, thereby ensuring the stability of the torsion spring during the operation of the switch.

[0050] The working principle of the utility model is:

[0051] In the initial state, the contact end of the moving contact piece 5 is separated from the stationary contact piece 6, and the movable end 81 of the torsion spring 8 in the annular cavity 31 is in the first opening 32;

[0052] like Figure 2 The moving contact piece is in contact with the stationary contact piece, and the switch is energized at this time:

[0053] The specific contact process is as follows: when the elevator baffle 100 touches the right guide wheel 14 on the first rotating seat 2, the right guide wheel 14 is pressed down by force and pushes the first rotating seat 2 to rotate and drives the second rotating seat 3 to rotate clockwise (the clockwise rotation is relative to the Figure 2 ), the contact end of the moving contact piece 5 contacts the stationary contact piece 6, and the switch is energized; at the same time, the tension spring 9 begins to compress, and the movable end 81 of the torsion spring 8 slides out of the first opening 32 along the arc transition surface 312 into the annular cavity 31, and abuts against the inner wall of the annular cavity 31 (such as Figure 2 shown),

[0054] When the moving contact piece is separated from the stationary contact piece, the switch is in the power-off state:

[0055] Specifically, when the baffle of the elevator moves away from the right guide wheel and touches the left guide wheel, it drives the first rotating seat 2 to rotate counterclockwise and drives the second rotating seat 3 to rotate counterclockwise (here, counterclockwise rotation is the opposite rotation of the above-mentioned clockwise rotation), the contact end of the moving contact piece 5 will separate from the static contact piece 6, and the switch will be powered off. During this process, the tension spring is reset, and the movable end 81 of the torsion spring 8 slides along the inner wall of the annular cavity 31 toward the first opening 32 until it finally enters the first opening 32 along the arc transition surface 313.

[0056] Of course, in other embodiments, the elastic member may be designed as either a torsion spring 8 or a tension spring 9 .

[0057] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
