Description

Technical Field

[0001] The invention belongs to the technical field of sealing equipment, in particular to a sealing connection seat for a cylinder member of a motor. Background Art

[0002] The motor sealing connector is a key component in the motor system that is used to connect the internal coil of the motor with the external cable and ensure that the connection has good sealing performance. It is usually designed with a structure to accommodate the cable connection terminals and uses sealing measures (such as sealing sleeves, sealing rings or sealing gaskets, etc.) to prevent external substances such as moisture and dust from invading the motor.

[0003] In the prior art, this is achieved through its internal sealing structure and components. When the cable passes through the connector and is connected to the internal coil of the motor, the sealing components such as the sealing sleeve, sealing ring or sealing gasket will fit tightly between the cable and the connector to form an effective sealing barrier, which can maintain the sealing effect during the operation of the motor and prevent external substances such as moisture and dust from invading the interior of the motor, thereby ensuring the safe and stable operation of the motor.

[0004] There are still some problems in the actual application of the above scheme. The sealing components such as the sealing sleeve in the motor sealing connector are exposed to the outside. When solid particles enter the sealing surface, 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, insulating materials, etc.) will be corroded by the external environment, thereby reducing the performance and service life of the motor. Secondly, during the operation of the motor, the added reciprocating buckle mechanism will not be able to keep its components in close contact with the side of the wire plug hole due to the influence of long-term vibration of the motor, which will cause the wire to be displaced, and then the connection between the wire and the internal circuit of the motor will become unstable, and may even become loose or fall off, which will directly affect the working performance and stability of the motor, and may even cause the motor to fail to work properly.

[0005] To this end, the present invention provides a sealing connection seat for a motor cylinder member. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is: the present invention is a sealing connection seat for a motor cylinder member, comprising a motor sealing connection seat, the motor sealing connection seat comprising a connection seat body, a wire insertion port is provided on the side of the connection seat body, and a reciprocating buckle mechanism is provided on the surface of the motor sealing connection seat; 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, and a sealing baffle is fixedly arranged at one end of the second slider. The movement of the sealing baffle can improve the sealing performance of the connecting seat body.

[0008] Preferably, a guide groove is provided 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 top of the first slider, the bottom of the hinge is fixedly connected to the top of the second slider, and a threading hole is provided through the middle of the sealing baffle.

[0009] Preferably, the guide groove opened in the middle of the first fixed plate can ensure that the first slider and the second slider will not be offset during the movement. The setting of the hinge facilitates the rotation of the first slider and the second slider, facilitates the insertion of wires at the wire insertion port, and improves the wire insertion efficiency. The wire threading port is used to place the line.

[0010] Preferably, an inner cavity is opened 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, a hook is fixedly connected to the other end of the first reciprocating spring, and a fixed baffle is fixedly connected to the upper part of the first fixed plate.

[0011] Preferably, the first reciprocating spring facilitates the stretching of the hook and can be easily disassembled through the setting of the hook. The hook is made of elastic material. The setting of the fixed baffle can make one side of the sealing baffle fit with one side of the wire insertion port to improve the internal sealing.

[0012] Preferably, a fixed limiting mechanism for fixing is arranged on the side of the reciprocating buckle mechanism, and the fixed limiting mechanism includes a guide block, and the guide block is fixedly connected to the side wall of the first fixed plate.

[0013] Preferably, a third sliding block is slidably connected inside the guide block, a first fixing hole is opened on the upper part of the third sliding block, a second fixing hole is opened on the upper part of the guide block, a pin is inserted inside the second fixing hole, and a second fixing plate is fixedly connected to the side of one end of the third sliding block.

[0014] Preferably, the first fixing holes are provided in several groups, and when the second fixing holes are aligned with any group of the first fixing holes, they are fixed by a latch, thereby improving the convenience of the device, and the bottom of the latch is a slope structure.

[0015] Preferably, the bottom of the guide block is fixedly connected to a limit frame, an inner cavity is opened inside the limit frame, a second reciprocating spring is fixedly connected to the side wall of the inner cavity of the limit frame, the other end of the second reciprocating spring is fixedly connected to a bidirectional oblique block, and a slot is opened at the bottom of the pin.

[0016] Preferably, the slope structure at the bottom of the pin is compatible with the slope structure of the bidirectional oblique block. When the bidirectional oblique block is engaged with the slot, the entire device can be fixed to prevent the reciprocating buckle mechanism from loosening due to vibration during operation of the motor, thereby improving the sealing of the reciprocating buckle mechanism.

[0017] The beneficial effects of the present invention are as follows: When the second slider is manually flipped to the initial state, the second slider is manually pushed to move in the direction of the fixed baffle, and the sealing baffle is driven to continuously approach the side of the wire insertion port while moving. When the sealing baffle is against the side of the wire insertion port, since the hook is a spring sheet, the side of the hook with the buckle is manually lifted and the hook is pulled to move in the direction away from the sealing baffle. At this time, the first reciprocating spring is in a stretched state. When the side of the hook with the buckle passes the fixed baffle, the hook returns to its initial state. At this time, the hook will be stuck with the fixed baffle, and the first reciprocating spring is still in a stretched state. The side of the sealing baffle can be tightly attached to the side of the wire insertion port by pulling the hook, thereby extending the service life of the sealing component and further improving the sealing performance of the connection seat.

[0018] 2. A sealing connection seat for a motor cylinder member described in the present invention, when the reciprocating buckle mechanism completes its work, the third sliding block is manually inserted into the guide groove opened inside the guide block, and the third sliding block is continuously pushed 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 are aligned with the second fixing holes opened through the guide block, the latch is manually inserted into the cylindrical hole formed by the second fixing hole and the first fixing hole, thereby fixing the reciprocating buckle mechanism to avoid loosening caused by motor vibration, further improving the sealing of the reciprocating buckle mechanism, and at the same time, the fixing of the latch can also make the side of the sealing baffle always close to the side of the wire insertion port to avoid long-term vibration of the motor This causes the plug wire to be displaced, thereby improving the stability of the motor connection. When the pin is inserted along the cylindrical hole formed by the second fixing hole and any group of the first fixing holes, since the bottom of the pin is provided with a slope structure adapted to the inclination of the slot, when the pin moves downward, the oblique structure at its bottom will continuously push the two-way oblique block to slide inward along the guide of the inner cavity of the limit frame. At this time, the second reciprocating spring is in a compressed state. When the slot opened at the bottom of the pin moves to the same horizontal plane as the two-way oblique block, the second reciprocating spring will push the two-way oblique block to reset because it is not squeezed by external force, and then the oblique structure of the two-way oblique block will be inserted into the slot. The cooperation of the two-way oblique block and the slot can achieve the purpose of convenient disassembly, thereby improving the efficiency of subsequent maintenance.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figures 1 to 8 As shown, a sealing connection seat for a motor cylinder member according to an embodiment of the present invention comprises a motor sealing connection seat 1, wherein the motor sealing connection seat 1 comprises a connection seat body 101, a wire insertion port 102 is provided on the side of the connection seat body 101, and a reciprocating buckle mechanism 2 is provided on the surface of the motor sealing connection seat 1; The reciprocating buckle mechanism 2 includes a first fixed plate 201 fixedly arranged on the connecting seat body 101, a second slider 204 is slidably arranged inside the first fixed plate 201, and a sealing baffle 205 is fixedly arranged at one end of the second slider 204. The movement of the sealing baffle 205 can improve the sealing performance of the connecting seat body 101.

[0023] Specifically, the sealing components such as the sealing sleeve in the motor sealing connector 1 are exposed to the outside. When solid particles enter the sealing surface, 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, insulating materials, etc.) will be corroded by the external environment, thereby reducing the performance and service life of the motor. Therefore, the present invention solves this problem by setting a corresponding structure. The present invention describes a sealing connector for a motor cylinder member. When it is necessary to assemble a connecting wire with a crystal head and a motor sealing connector 1, the plug wire is manually inserted into the plug-in port 102 through a sealing component. However, since the sealing components such as the sealing sleeve in the motor sealing connector 1 are exposed to the outside, when solid particles enter the sealing surface, these particles will act as abrasives, causing the sealing component to be severely worn and fail. When the sealing component fails, 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 in the first fixed plate 201 is manually pushed to drive the sealing baffle 205 to move toward the side of the plug-in port 102. The setting of the sealing baffle 205 can reduce the intrusion of solid particles into the sealing surface, thereby extending the service life of the sealing component and improving the sealing performance of the sealing component.

[0024] Embodiment 2 like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is: like Figure 4 As shown, in this embodiment, a guide groove is opened inside the first fixed plate 201, and the first slider 202 is slidably connected to the guide groove inside the first fixed plate 201. The upper part of the first slider 202 is fixedly connected to a hinge 203, and the bottom of the hinge 203 is fixedly connected to the top of the second slider 204. A threading hole 206 is opened through the middle of the sealing baffle 205.

[0025] Specifically, when it is necessary to plug in the wires inside the plug port 102, the staff manually pushes the first slider 202 along the guide groove opened inside the first fixed plate 201 to move toward the sealing baffle 205, and the hinge 203, the second slider 204, the sealing baffle 205 and the threading port 206 are pushed to move synchronously during the movement. When the hinge 203 moves to the side of the first fixed plate 201 close to the sealing baffle 205, the second slider 204 is manually rotated. At this time, the connecting wire with a crystal head at one end is placed at the position of the plug port 102, and the other end without a crystal head is manually passed through the threading port 206. At this time, the second slider 204 is manually rotated to restore the second slider 204 to its initial state. The setting of the threading port 206 can prevent the connecting wires from getting tangled and becoming indistinguishable.

[0026] like Figure 4 and Figure 5 As shown, in this embodiment, an inner cavity is opened at one end of the first slider 202, a first reciprocating spring 207 is fixedly connected to the side wall of the inner cavity of the first slider 202, a hook 208 is fixedly connected to the other end of the first reciprocating spring 207, and a fixed baffle 209 is fixedly connected to the upper part of the first fixed plate 201.

[0027] Specifically, when the second slider 204 is manually flipped to the initial state, the second slider 204 is manually pushed to move toward the fixed baffle 209, and the sealing baffle 205 is continuously moved closer to the side of the plug-in port 102 while moving. When the sealing baffle 205 abuts against the side of the plug-in port 102, since the hook 208 is a spring, the side of the hook 208 with the buckle is manually lifted, and the hook 208 is pulled to move away from the sealing baffle 205. At this time, the first slider 204 is pushed toward the fixed baffle 209, and the sealing baffle 205 is continuously moved closer to the side of the plug-in port 102. The reciprocating spring 207 is in a stretched state. When the side of the hook 208 with the 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 pulled state. The pulling of the hook 208 can make the side of the sealing baffle 205 close to the side of the wire plug 102, reducing the situation of solid particles invading the sealing surface, thereby extending the service life of the sealing component and improving the sealing of the connecting seat.

[0028] like Figure 3 As shown, a fixed limiting mechanism 3 for fixing is arranged on the side of the reciprocating buckle mechanism 2 of this embodiment. The fixed limiting mechanism 3 includes a guide block 301 , and the guide block 301 is fixedly connected to the side wall of the first fixed plate 201 .

[0029] like Figure 7As shown, the guide block 301 of this embodiment is internally slidably connected with a third sliding block 302, the third sliding block 302 is provided with a first fixing hole 303 on the upper portion, the guide block 301 is provided with a second fixing hole 304 on the upper portion, the second fixing hole 304 is plugged with a pin 305, and the side surface of one end of the third sliding block 302 is fixedly connected with a second fixing plate 306.

[0030] Specifically, when the reciprocating snap mechanism 2 completes its work, the third sliding block 302 and the second fixing plate 306 are manually inserted along the guide groove opened inside the guide block 301, and the third sliding block 302 is continuously pushed 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 holes 304 opened through the guide block 301, the latch 305 is manually inserted along the cylindrical hole formed by the second fixing hole 304 and the first fixing hole 303, so that the reciprocating snap mechanism 2 can be fixed to avoid the loosening of the reciprocating snap mechanism 2 caused by the vibration of the motor, and further improve the sealing of the reciprocating snap mechanism 2. At the same time, through the fixation of the latch 305, the side of the sealing baffle 205 can always be in close contact with the side of the wire plug port 102, avoiding the displacement of the plug wire due to long-term vibration of the motor, thereby improving the stability of the motor connection.

[0031] like Figure 8 As shown, the bottom of the guide block 301 described in this embodiment is fixedly connected to a limit frame 307, 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 oblique block 309, and a slot 310 is opened at the lower part of the pin 305.

[0032] Specifically, when the latch 305 is inserted along the cylindrical hole formed by the second fixing hole 304 and any group of first fixing holes 303, since the bottom of the latch 305 is provided with a slope structure adapted to the inclination of the slot 310, when the latch 305 moves downward, the oblique structure at its bottom will continuously push the two-way oblique block 309 to slide inward along the guide of the inner cavity of the limit frame 307. At this time, the second reciprocating spring 308 is in a compressed state. When the slot 310 opened at the bottom of the latch 305 moves to the same horizontal plane as the two-way oblique block 309, the second reciprocating spring 308 will push the two-way oblique block 309 to reset due to the lack of external force, and then the oblique structure of the two-way oblique block 309 will be inserted into the slot 310. The cooperation between the two-way oblique block 309 and the slot 310 can achieve the purpose of convenient disassembly and improve the efficiency of subsequent maintenance.

[0033] Working principle: when it is necessary to plug in the wires inside the wire socket 102, the staff manually pushes the first slider 202 along the guide groove opened inside the first fixed plate 201 to move toward the sealing baffle 205, and the hinge 203, the second slider 204, the sealing baffle 205 and the threading port 206 are pushed to move synchronously during the movement. When the hinge 203 moves to the side of the first fixed plate 201 close to the sealing baffle 205, the second slider 204 is manually rotated. At this time, the connecting wire with a crystal head at one end is placed at the position of the wire socket 102, and the other end without a crystal head is manually passed through the threading port 206. At this time, the second slider 204 is manually rotated to restore the second slider 204 to its initial state. The setting of the threading port 206 can prevent the connecting wires from getting tangled and making it impossible to distinguish.

[0034] When the second slider 204 is manually flipped to the initial state, the second slider 204 is manually pushed to move toward the fixed baffle 209, and the sealing baffle 205 is driven to continuously approach the side of the wiring port 102 while moving. When the sealing baffle 205 is against the side of the wiring port 102, since the hook 208 is a spring, the side of the hook 208 with the buckle is manually lifted and the hook 208 is pulled to move 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 the 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. The pulling of the hook 208 can make the side of the sealing baffle 205 close to the side of the wiring port 102, thereby extending the service life of the sealing component and thereby improving the sealing of the connecting seat.

[0035] When the reciprocating buckle mechanism 2 completes its work, the third sliding block 302 and the second fixing plate 306 are manually inserted along the guide groove opened inside the guide block 301, and the third sliding block 302 is continuously pushed 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 holes 304 opened through the guide block 301, the latch 305 is manually inserted along the cylindrical hole formed by the second fixing hole 304 and the first fixing hole 303, so that the reciprocating buckle mechanism 2 can be fixed to avoid the loosening of the reciprocating buckle mechanism 2 caused by the vibration of the motor, and further improve the sealing of the reciprocating buckle mechanism 2. At the same time, through the fixation of the latch 305, the side of the sealing baffle 205 can always be in close contact with the side of the wire plug port 102, avoiding the displacement of the plug wire due to long-term vibration of the motor, thereby improving the stability of the motor connection.

[0036] When the latch 305 is inserted along the cylindrical hole formed by the second fixing hole 304 and any group of first fixing holes 303, since the bottom of the latch 305 is provided with a slope structure adapted to the inclination of the slot 310, when the latch 305 moves downward, the oblique structure at its bottom will continuously push the two-way oblique block 309 to slide inward along the guide of the inner cavity of the limit frame 307. At this time, the second reciprocating spring 308 is in a compressed state. When the slot 310 opened at the bottom of the latch 305 moves to the same horizontal plane as the two-way oblique block 309, the second reciprocating spring 308 will push the two-way oblique block 309 to reset due to the lack of external force, and then the oblique structure of the two-way oblique block 309 will be inserted into the slot 310. The cooperation between the two-way oblique block 309 and the slot 310 can achieve the purpose of convenient disassembly and improve the efficiency of subsequent maintenance.
