Description

Technical Field

[0001] The present invention belongs to the technical field of sealing equipment, and specifically relates to a sealing connection seat for a motor cylinder-piercing component. Background Art

[0002] A motor sealing connection seat is a key component in a motor system for connecting the internal coil of the motor to an external cable and ensuring good sealing performance at the connection. It is usually designed with a structure for accommodating cable connection terminals and uses sealing measures (such as a sealing sleeve, sealing ring, or gasket, etc.) to prevent external substances such as moisture and dust from entering the interior of the motor.

[0003] In the prior art, it is achieved through its internal sealing structure and components. When the cable passes through the connection seat and connects to the internal coil of the motor, sealing components such as a sealing sleeve, sealing ring, or gasket will closely fit between the cable and the connection seat, forming an effective sealing barrier that can continuously maintain the sealing effect during the operation of the motor, preventing external substances such as moisture and dust from entering the interior of the motor, thereby ensuring the safe and stable operation of the motor.

[0004] The above solution still has some problems in practical applications. The sealing components such as the sealing sleeve in the motor sealing connection seat are exposed. When solid particles enter at the sealing surface, these particles will act as abrasives, causing severe wear and failure of the sealing components. When the sealing components fail, the electrical components inside the motor (such as coils, insulating materials, etc.) will be eroded by the external environment, thereby reducing the performance and service life of the motor. Secondly, due to the influence of the long-term vibration of the motor during the operation of the motor, the components of the added reciprocating buckle mechanism cannot always remain in close contact with the side of the wire insertion hole, which will cause the wire insertion to be displaced, and further cause the connection between the wire insertion and the internal circuit of the motor to become unstable, and even may become loose or fall off, which will directly affect the working performance and stability of the motor, and may even cause the motor to malfunction.

[0005] Therefore, the present invention provides a sealing connection seat for a motor cylinder-piercing component. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A sealing connection seat for a motor cylinder-piercing component according to the present invention includes a motor sealing connection seat. The motor sealing connection seat includes a connection seat body. An insertion opening is provided on the side of the connection seat body. A reciprocating buckle mechanism is provided on the surface of the motor sealing connection seat;

[0008] The reciprocating buckle mechanism includes a first fixed plate fixedly arranged on the connecting seat body. A second slider is slidably arranged inside the first fixed plate. One end of the second slider is fixedly provided with a sealing baffle. The sealing performance of the connecting seat body can be improved by the movement of the sealing baffle.

[0009] Preferably, a guide groove is formed inside the first fixed plate. A first slider is slidably connected to the guide groove inside the first fixed plate. A hinge is fixedly connected to the upper part of the first slider. The bottom of the hinge is fixedly connected to the top of the second slider. A wire passing opening is formed through the middle of the sealing baffle.

[0010] Preferably, the guide groove formed in the middle of the first fixed plate can ensure that the first slider and the second slider do not deviate during the movement process. The setting of the hinge facilitates the rotation of the first slider and the second slider, facilitates the insertion of wires into the wire insertion opening, and improves the wire insertion efficiency. The wire passing opening is used for placing wires.

[0011] Preferably, an inner cavity is formed at one end of the first slider. A first reciprocating spring is fixedly connected to the side wall of the inner cavity of the first slider. The other end of the first reciprocating spring is fixedly connected to a hook. A fixed baffle is fixedly connected to the upper part of the first fixed plate.

[0012] Preferably, the first reciprocating spring facilitates the stretching of the hook. At the same time, the setting of the hook facilitates disassembly. The hook is made of an elastic material. The setting of the fixed baffle can make one side of the sealing baffle fit with one side of the wire insertion opening, improving the internal sealing performance.

[0013] Preferably, a fixed limiting mechanism for fixation is arranged on the side of the reciprocating buckle mechanism. The fixed limiting mechanism includes a guide block, and the guide block is fixedly connected to the side wall of the first fixed plate.

[0014] Preferably, a third slider is slidably connected inside the guide block. A first fixing hole is formed in the upper part of the third slider. A second fixing hole is formed in the upper part of the guide block. A pin is inserted into the second fixing hole. One side of one end of the third slider is fixedly connected to a second fixed plate.

[0015] Preferably, several groups of first fixing holes are formed. When the second fixing hole is aligned with any group of first fixing holes, it is fixed by the pin, improving the convenience of the device. The bottom of the pin is of a slope structure.

[0016] Preferably, a limiting frame is fixedly connected to the bottom of the guide block. An inner cavity is formed inside the limiting frame. A second reciprocating spring is fixedly connected to the side wall of the inner cavity of the limiting frame. The other end of the second reciprocating spring is fixedly connected to a bidirectional inclined block. A card slot is formed in the lower part of the pin.

[0017] Preferably, the ramp structure at the bottom of the bolt is adapted to the ramp structure of the bidirectional inclined block. When the bidirectional inclined block is clamped with the card slot, the whole device can be fixed, preventing the reciprocating buckle mechanism from loosening due to vibration during the operation of the motor, thereby improving the sealing performance of the reciprocating buckle mechanism.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For the sealed connection seat for the motor cylinder-piercing part of the present invention, when the second slider is manually flipped to the initial state, by manually pushing the second slider towards the fixed baffle and driving the sealed baffle to continuously approach the side of the wire insertion port while moving. When the sealed baffle abuts against the side of the wire insertion port, since the hook is a elastic piece, so by manually lifting the side of the hook with the buckle and simultaneously pulling the hook away from the sealed baffle, at this time the first reciprocating spring is in a stretched state. When the side of the hook with the buckle passes over the fixed baffle, the hook returns to the initial state, and at this time the hook will be stuck with the fixed baffle, and the first reciprocating spring is still in a stretched state. By pulling the hook, the side of the sealed baffle can be closely attached to the side of the wire insertion port, thus extending the service life of the sealing component and further improving the sealing performance of the connection seat.

[0020] 2. For the sealed connection seat for the motor cylinder-piercing part of the present invention, when the reciprocating buckle mechanism finishes working, manually insert the third sliding block and the second fixed plate along the guide groove opened inside the guide block, and continuously push the third sliding block to move along the direction of the guide groove of the guide block. When any group of first fixing holes opened on the side wall of the third sliding block is aligned with the second fixing hole penetratingly opened on the guide block, manually insert the bolt along the cylindrical hole formed by the second fixing hole and the first fixing hole, thereby fixing the reciprocating buckle mechanism, preventing the loosening phenomenon of the reciprocating buckle mechanism caused by the vibration of the motor, further improving the sealing performance of the reciprocating buckle mechanism. At the same time, through the fixing of the bolt, the side of the sealed baffle can always be closely attached to the side of the wire insertion port, avoiding the displacement of the wire caused by the long-term vibration of the motor, and further improving the stability of the motor connection. When the bolt is inserted along the cylindrical hole formed by the second fixing hole and any group of first fixing holes, since the bottom of the bolt is provided with a ramp structure adapted to the inclination of the card slot, when the bolt moves downward, it will continuously push the bidirectional inclined block to slide inward along the guide in the inner cavity of the limit frame through the inclined structure at its bottom. At this time, the second reciprocating spring is in a compressed state. When the card slot opened at the bottom of the bolt moves to the same horizontal plane as the bidirectional inclined block, the second reciprocating spring will push the bidirectional inclined block to reset because it is not extruded by external force, and then the inclined structure of the bidirectional inclined block will be inserted into the card slot. Through the cooperation of the bidirectional inclined block and the card slot, the purpose of convenient disassembly can be achieved, improving the efficiency of subsequent maintenance.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Embodiment 1

[0035] AsFigures 1 to 8 As shown in the figure, a sealing connection seat for a motor cylinder-piercing part according to an embodiment of the present invention includes a motor sealing connection seat 1. The motor sealing connection seat 1 includes a connection seat body 101. An insertion port 102 is formed on the side of the connection seat body 101. A reciprocating buckle mechanism 2 is arranged on the surface of the motor sealing connection seat 1;

[0036] The reciprocating buckle mechanism 2 includes a first fixing plate 201 fixedly arranged on the connection seat body 101. A second slider 204 is slidably arranged inside the first fixing plate 201. One end of the second slider 204 is fixedly provided with a sealing baffle 205. The sealing performance of the connection seat body 101 can be improved by the movement of the sealing baffle 205.

[0037] Specifically, sealing components such as the sealing sleeve in the motor sealing connection seat 1 are exposed. When solid particles enter the sealing surface at this time, these particles will act as abrasives, causing the sealing components to be severely worn and fail. When the sealing components fail, the electrical components (such as coils, insulating materials, etc.) inside the motor will be eroded by the external environment, thereby reducing the performance and service life of the motor;

[0038] Therefore, the present invention solves this problem by setting corresponding structures. For a sealing connection seat for a motor cylinder-piercing part according to the present invention, when assembling a connecting wire with a crystal head to the motor sealing connection seat 1, the insertion wire is manually inserted into the insertion port 102 through the sealing component. However, since sealing components such as the sealing sleeve in the motor sealing connection seat 1 are exposed, when solid particles enter the sealing surface at this time, these particles will act as abrasives, causing the sealing components to be severely worn and fail. When the sealing components fail, the electrical components inside the motor, such as coils and insulating materials, will be eroded by the external environment, thereby reducing the performance and service life of the motor. At this time, the second slider 204 sliding inside the first fixing plate 201 is manually pushed, and the sealing baffle 205 is driven to move towards the side of the insertion port 102. By the setting of the sealing baffle 205, the intrusion of solid particles into the sealing surface can be reduced, thereby extending the service life of the sealing components and improving the sealing performance of the sealing components.

[0039] Embodiment Two

[0040] As Figures 2 to 8 shown, compared with Embodiment One, another implementation manner of the present invention is:

[0041] As Figure 4As shown in the figure, a guide groove is provided inside the first fixing plate 201 of this embodiment. A first slider 202 is slidably connected to the guide groove inside the first fixing plate 201. The upper part of the first slider 202 is fixedly connected to a hinge 203. The bottom of the hinge 203 is fixedly connected to the top of a second slider 204. A wire passing opening 206 is formed through the middle of the sealing baffle 205.

[0042] Specifically, when it is necessary to insert a wire into the wire insertion port 102, the staff manually pushes the first slider 202 along the guide groove provided inside the first fixing plate 201 in the direction of the sealing baffle 205. During the movement, the hinge 203, the second slider 204, the sealing baffle 205, and the wire passing opening 206 will be pushed to move synchronously. When the hinge 203 moves to the side of the first fixing plate 201 close to the sealing baffle 205, the second slider 204 is manually rotated. At this time, a connecting wire with a crystal head at one end is placed at the position of the wire insertion port 102, and the other end without a crystal head is manually passed through the wire passing opening 206. Then, the second slider 204 is manually rotated again to make the second slider 204 return to the initial state. The setting of the wire passing opening 206 can prevent the connecting wires from being entangled and indistinguishable.

[0043] As Figure 4 and Figure 5 As shown in the figure, an inner cavity is provided at one end of the first slider 202 of this embodiment. A first reciprocating spring 207 is fixedly connected to the side wall of the inner cavity of the first slider 202. The other end of the first reciprocating spring 207 is fixedly connected to a hook 208. A fixed baffle 209 is fixedly connected to the upper part of the first fixing plate 201.

[0044] Specifically, when the second slider 204 is manually flipped to the initial state, the second slider 204 is manually pushed in the direction of the fixed baffle 209, and during the movement, the sealing baffle 205 will be continuously driven to approach the side of the wire insertion port 102. When the sealing baffle 205 abuts against the side of the wire insertion port 102, since the hook 208 is a spring piece, the side of the hook 208 with a buckle is manually lifted, and at the same time, the hook 208 is pulled in the direction away from the sealing baffle 205. At this time, the first reciprocating spring 207 is in a stretched state. When the side of the hook 208 with a buckle passes over the fixed baffle 209, the hook 208 returns to the initial state. At this time, the hook 208 will be stuck with the fixed baffle 209, and the first reciprocating spring 207 is still in a stretched state. By pulling the hook 208, the side of the sealing baffle 205 can be closely attached to the side of the wire insertion port 102, reducing the situation of solid particles invading the sealing surface, thereby extending the service life of the sealing component and improving the sealing performance of the connector.

[0045] As Figure 3As shown in the figure, a fixed limit mechanism 3 for fixing is provided on the side of the reciprocating buckle mechanism 2 in this embodiment. The fixed limit mechanism 3 includes a guide block 301, and the guide block 301 is fixedly connected to the side wall of the first fixing plate 201.

[0046] As Figure 7 As shown in the figure, a third sliding block 302 is slidably connected inside the guide block 301 in this embodiment. A first fixing hole 303 is opened in the upper part of the third sliding block 302, a second fixing hole 304 is opened in the upper part of the guide block 301, a pin 305 is inserted into the second fixing hole 304, and a second fixing plate 306 is fixedly connected to the side of one end of the third sliding block 302.

[0047] Specifically, when the reciprocating buckle mechanism 2 finishes working, manually insert the third sliding block 302 and the second fixing plate 306 along the guide groove opened inside the guide block 301, and continuously push the third sliding block 302 to move along the direction of the guide groove of the guide block 301. When any group of first fixing holes 303 opened on the side wall of the third sliding block 302 is aligned with the second fixing hole 304 penetratingly opened on the guide block 301, manually insert the pin 305 along the cylindrical hole formed by the second fixing hole 304 and the first fixing hole 303, so as to fix the reciprocating buckle mechanism 2, avoid the loosening phenomenon caused by the influence of the motor vibration on the reciprocating buckle mechanism 2, further improve the sealing performance of the reciprocating buckle mechanism 2, and at the same time, through the fixation of the pin 305, the side of the sealing baffle 205 can always be closely attached to the side of the wire insertion port 102, avoid the situation of wire displacement caused by the long-term vibration of the motor, and further improve the stability of the motor connection.

[0048] As Figure 8 As shown in the figure, a limit frame 307 is fixedly connected to the bottom of the guide block 301 in this embodiment. An inner cavity is opened inside the limit frame 307. A second reciprocating spring 308 is fixedly connected to the side wall of the inner cavity of the limit frame 307. The other end of the second reciprocating spring 308 is fixedly connected to a bidirectional inclined block 309. A card slot 310 is opened in the lower part of the pin 305.

[0049] Specifically, when the bolt 305 is inserted along the cylindrical hole formed by the second fixing hole 304 and any set of the first fixing holes 303, since a ramp structure adapted to the inclination of the card slot 310 is provided at the bottom of the bolt 305, when the bolt 305 moves downward, it will continuously push the bidirectional inclined block 309 to slide inward along the guide in the inner cavity of the limit frame 307 through the inclined structure at its bottom. At this time, the second reciprocating spring 308 is in a compressed state. When the card slot 310 opened at the bottom of the bolt 305 moves to the same horizontal plane as the bidirectional inclined block 309, the second reciprocating spring 308 will push the bidirectional inclined block 309 to reset because it is not extruded by an external force. Furthermore, the inclined structure of the bidirectional inclined block 309 will be inserted into the card slot 310. Through the cooperation of the bidirectional inclined block 309 and the card slot 310, the purpose of convenient disassembly can be achieved, and the efficiency of subsequent maintenance can be improved.

[0050] Working principle: When it is necessary to insert a wire into the wire insertion port 102, the staff manually pushes the first slider 202 along the guide groove formed inside the first fixing plate 201 in the direction of the sealing baffle 205. During the movement, the hinge 203, the second slider 204, the sealing baffle 205, and the wire passing port 206 will be pushed to move synchronously. When the hinge 203 moves to the side of the first fixing plate 201 close to the sealing baffle 205, the second slider 204 is manually rotated. At this time, a connecting wire with a crystal head at one end is placed at the position of the wire insertion port 102, and the other end without a crystal head is manually passed through the wire passing port 206. Then, the second slider 204 is manually rotated again to make the second slider 204 return to its initial state. Through the setting of the wire passing port 206, it can be avoided that the connecting wires are entangled together, resulting in a situation where they cannot be distinguished.

[0051] When the second slider 204 is manually flipped back to its initial state, the second slider 204 is manually pushed in the direction of the fixed baffle 209, and at the same time of the movement, it will drive the sealing baffle 205 to continuously approach the side of the wire insertion port 102. When the sealing baffle 205 abuts against the side of the wire insertion port 102, since the hook 208 is a spring piece, the side of the hook 208 with a buckle is manually lifted, and at the same time, the hook 208 is pulled in the direction away from the sealing baffle 205. At this time, the first reciprocating spring 207 is in a stretched state. When the side of the hook 208 with a buckle passes over the fixed baffle 209, the hook 208 returns to its initial state. At this time, the hook 208 will be stuck with the fixed baffle 209, and the first reciprocating spring 207 is still in a stretched state. By pulling the hook 208, the side of the sealing baffle 205 can be closely attached to the side of the wire insertion port 102, so as to extend the service life of the sealing component and further improve the sealing performance of the connector.

[0052] When the reciprocating buckle mechanism 2 finishes its work, manually insert the third sliding block 302 and the second fixed plate 306 along the guide groove formed inside the guide block 301, and continuously push the third sliding block 302 to move along the direction of the guide groove of the guide block 301. When any set of first fixing holes 303 formed on the side wall of the third sliding block 302 aligns with the second fixing hole 304 penetrating through the guide block 301, manually insert the bolt 305 along the cylindrical hole formed by the second fixing hole 304 and the first fixing hole 303, so as to fix the reciprocating buckle mechanism 2, avoid the loosening phenomenon caused by the influence of the motor vibration on the reciprocating buckle mechanism 2, further improve the sealing performance of the reciprocating buckle mechanism 2, and at the same time, through the fixation of the bolt 305, the side surface of the sealing baffle 205 can always be closely attached to the side surface of the wire insertion port 102, avoid the situation that the wire insertion is displaced due to the long-term vibration of the motor, and thus improve the stability of the motor connection.

[0053] When the bolt 305 is inserted along the cylindrical hole formed by the second fixing hole 304 and any set of first fixing holes 303, since a ramp structure adapted to the inclination of the card slot 310 is provided at the bottom of the bolt 305, when the bolt 305 moves downward, it will continuously push the bidirectional inclined block 309 to slide inward along the guide inside the inner cavity of the limit frame 307 through the inclined structure at its bottom. At this time, the second reciprocating spring 308 is in a compressed state. When the card slot 310 formed at the bottom of the bolt 305 moves to the same horizontal plane as the bidirectional inclined block 309, the second reciprocating spring 308 will push the bidirectional inclined block 309 to reset because it is not subjected to external extrusion, and then the inclined structure of the bidirectional inclined block 309 will be inserted into the card slot 310. Through the cooperation of the bidirectional inclined block 309 and the card slot 310, the purpose of convenient disassembly can be achieved, and the efficiency of subsequent maintenance can be improved.
