Description

Technical Field

[0001] The invention belongs to the technical field of vibration reduction, and in particular relates to a solenoid valve vibration reducer, and specifically to a connection structure between a solenoid valve solenoid and a vibration reducer of the solenoid valve vibration reducer. Background Art

[0002] A solenoid valve shock absorber is a shock absorber that changes the damping of the shock absorber by controlling the flow rate through a solenoid valve. The solenoid valves used in solenoid valve shock absorbers are either built-in or external. The external solenoid valve type is more widely used and has more structural types. However, the connection method between the external solenoid valve and the shock absorber body mostly uses the solenoid of the solenoid valve to seal with a round wire retaining spring or glue, and then connects by riveting or other methods.

[0003] In the current solenoid valve damper with better quality, the connection between the solenoid in the external solenoid valve and the solenoid valve gland adopts the method of three-point connection between the round wire circlip and the solenoid valve gland, and then the solenoid valve gland is connected to the solenoid valve seat by screw connection. However, this method has the problem that the circlip is not installed properly, or there is an axial shaking gap after the solenoid is installed, which makes the solenoid easy to fall off after being stressed, and then causes the solenoid valve to fail to pass current and other faults, which brings troubles to the normal use of the solenoid valve damper. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, the present invention proposes a connection structure between a solenoid valve and a shock absorber of a solenoid valve shock absorber, which makes assembly simple and the structural connection stable.

In the present invention, the cross-section of the retaining ring is a right-angle trapezoid, and the outer side of the retaining ring is an inclined surface, and the outer diameter of the side facing the solenoid valve cover is smaller than the outer diameter of the side facing away from the solenoid valve cover. Correspondingly, the inner side surface of the installation retaining ring of the solenoid valve cover is an inclined surface, and the inclination angle is consistent with the outer side surface of the retaining ring. The minimum inner diameter of the installation retaining ring is smaller than the maximum outer diameter of the retaining ring, and the maximum inner diameter of the installation retaining ring is larger than the minimum outer diameter of the retaining ring.

[0006] In the present invention, a sealing ring is arranged between the solenoid and the solenoid valve gland, and the mounting clamp ring is located between the clamp spring and the sealing ring.

[0007] In the present invention, the clamping spring is in the shape of an open ring.

[0008] The present invention also includes a retaining spring resetting mechanism for assisting the retaining spring to escape.

[0009] Furthermore, the retaining spring reset mechanism is detachably sleeved on the end of the solenoid, and includes a reset body and a necking. The reset body is tubular, with one end being empty or closed and the necking located at the other end. The inner diameter of the necking is smaller than the inner diameter of the reset body, and the necking is clearance-matched with the outer side surface of the end of the solenoid. The length of the reset body is not less than the distance between the end of the solenoid and the mounting groove.

[0010] Furthermore, the necking is in the shape of a ring with a circular or elliptical cross section, and is an integral structure with the reset body.

[0011] Furthermore, the retaining spring reset mechanism is arranged on the solenoid, including an adjusting bolt and a traction rope, the retaining spring includes two symmetrically arranged half pieces, and buffer grooves are opened at the centers of the two half pieces respectively corresponding to the mounting grooves, and a compression spring is arranged in the buffer groove to support the retaining spring, and an adjusting hole is opened on the spiral tube perpendicular to the plane where the retaining spring is located, the adjusting bolt is inserted into the adjusting hole, and a wire passing channel is opened from the bottom of the adjusting hole to the two buffer grooves, the traction rope is inserted in the wire passing channel, one end of the traction rope passes through the buffer groove and the compression spring and is connected to the retaining spring, and the other end is connected to the adjusting bolt and is wound around the adjusting bolt as the adjusting bolt rotates.

[0012] Furthermore, the two wire-passing channels have the same length, the two traction ropes have the same length, and the distances between the adjustment bolt and the two buffer grooves are the same.

[0013] Furthermore, a through hole is opened at the position of the retaining spring corresponding to the buffer groove, and a connecting block is provided at the end of the traction rope in the buffer groove. The connecting block passes through the through hole from the inner side of the retaining spring, and a fastening bolt is provided on the outer side of the retaining spring and passes through the through hole. The fastening bolt is threadedly connected to the connecting block.

[0014] Furthermore, the through hole provided on the retaining ring is a countersunk hole, and the fastening bolt is hidden in the countersunk hole.

[0015] Compared with the prior art, the present invention has the following advantages: (1) The present invention can assist the solenoid to be accurately inserted into the corresponding position through the guiding effect of the inclined surface of the retaining spring and the inclined surface of the retaining ring of the solenoid valve gland, and the assembly operation is simple. After the retaining spring is inserted, it will naturally retract and can press against the edge of the retaining ring of the solenoid valve gland, so that the connection is firm and prevents slipping; (2) The present application arranges the sealing ring, mounting clamp ring and retaining spring continuously, which ensures the sealing effect between the solenoid and the solenoid valve gland while connecting and fixing them; (3) The retaining spring structure of the present application leaves room for the elastic effect of passing over the mounting retaining ring and then retracting, thereby avoiding stress accumulation inside the retaining spring structure, thereby effectively extending the service life of the retaining spring; (4) The two types of retaining spring reset mechanisms of the present application can conveniently move the firmly clamped retaining spring so that it can be retracted into the installation groove, thereby facilitating the disassembly of the solenoid and the solenoid valve cover and facilitating maintenance.

A rectangular mounting groove 3 is provided on the solenoid 1, and a retaining ring 4 is provided in the mounting groove 3. An inwardly protruding mounting snap ring 5 is provided on the inner side of the solenoid valve gland 2. The mounting snap ring 5 is located between the retaining ring 4 and the sealing ring 6, and is clamped on the outer side of the retaining ring 4. Figure 2In the figure, the retaining spring 4 is an open ring, the end face of the retaining spring 4 is a right-angled trapezoid, the outer side surface of the retaining spring 4 is an inclined surface, the outer diameter of the side facing the solenoid valve cover 2 is smaller than the outer diameter of the side facing away from the solenoid valve cover 2, and correspondingly, the inner side surface of the mounting retaining ring 5 of the solenoid valve cover 2 is an inclined surface matching the retaining spring 4, the minimum inner diameter of the mounting retaining ring 5 is smaller than the maximum outer diameter of the retaining spring 4, and the maximum inner diameter of the mounting retaining ring 5 is larger than the minimum outer diameter of the retaining spring 4, so that when the retaining spring 4 falls into the inner side of the mounting retaining ring 5, it can stably support the mounting retaining ring 5 to prevent displacement.

[0020] This embodiment is applied to the solenoid valve damper. When it is installed and used, the retaining spring 4 is first clamped in the installation groove 3 of the solenoid 1. The inclined surface of the retaining spring 4 is tapered outward. Then the sealing ring 6 is placed in the solenoid valve gland 2. The lower part of the solenoid valve gland 2 is screwed onto the solenoid valve seat. Then the solenoid 1 is inserted from the upper part of the solenoid valve gland 2. The inclined surface of the retaining spring 4 contacts the inclined surface of the installation retaining ring 5. When subjected to force, the installation retaining ring 5 guides the retaining spring 4 to contract. After passing through the installation retaining ring 5, the retaining spring 4 is naturally released and rebounds, and the installation retaining ring 5 is supported, and cooperates with the sealing ring 6 to achieve a firm sealing connection between the solenoid 1 and the solenoid valve gland 2. Example

[0021] A solenoid valve solenoid and shock absorber connection structure of a solenoid valve shock absorber, such as Figure 3 As shown, it includes a solenoid 1 and a solenoid valve gland 2, one end of the solenoid 1 is inserted into the solenoid valve gland 2, and sealing is achieved by a sealing ring 6. A rectangular mounting groove 3 is provided on the solenoid 1, and a retaining ring 4 is provided in the mounting groove 3. An inwardly protruding mounting snap ring 5 is provided on the inner side of the solenoid valve gland 2. The mounting snap ring 5 is located between the retaining ring 4 and the sealing ring 6 and is clamped on the outer side of the retaining ring 4. The retaining ring 4 is an open ring, and the end face of the retaining ring 4 is a right-angled trapezoid. The outer side surface of the retaining ring 4 is an inclined surface, and the outer diameter of the side facing the solenoid valve gland 2 is smaller than the outer diameter of the side facing away from the solenoid valve gland 2. Correspondingly, the inner side surface of the mounting snap ring 5 of the solenoid valve gland 2 is an inclined surface matched with the retaining ring 4, and the minimum inner diameter of the mounting snap ring 5 is smaller than the maximum outer diameter of the retaining ring 4, and the maximum inner diameter of the mounting snap ring 5 is larger than the minimum outer diameter of the retaining ring 4, so that when the retaining ring 4 falls into the inner side of the mounting snap ring 5, it can stably support the mounting snap ring 5 to avoid displacement.

[0022] This embodiment also includes a spring reset mechanism that assists the spring 4 to escape, and the spring reset mechanism is detachably sleeved on the end of the solenoid 1. Figure 4 In the figure, the retaining spring reset mechanism includes a reset body 7 and a necking 8. The reset body 7 is tubular, one end of which is closed, and the necking 8 is located at the other end. The necking 8 is a ring with an elliptical end face, and is an integral structure with the reset body 7. The inner diameter of the necking 8 is smaller than the inner diameter of the reset body 7. The necking 8 is clearance-matched with the outer side surface of the solenoid 1, and the length of the reset body 7 is not less than the distance between the end of the solenoid 1 and the mounting groove 3.

[0023] The present embodiment is applied to the solenoid valve damper. When it needs to be disassembled for maintenance, the solenoid valve gland 2 is first unscrewed from the solenoid valve seat, and the neck 8 of the retaining spring reset mechanism is aligned with the solenoid 1 and buckled on the end of the solenoid 1. The inclined surface inside the neck 8 is placed on the outside of the end of the solenoid 1. The neck 8 can be expanded and sleeved on the outside of the solenoid 1 by pushing inward. The neck 8 is continuously pushed inward so that the neck 8 squeezes the retaining spring 4 to shrink. At the same time, the solenoid 1 is pulled outward so that the contracted retaining spring 4 passes over the lower side of the mounting retaining ring 5. Then the retaining spring 4 can be naturally released and rebounded while being disengaged under the guidance of the inclined surface of the mounting retaining ring 5. At this time, the retaining spring reset mechanism can be removed, and the solenoid 1 is also separated from the solenoid valve gland 2; at this time, the retaining spring 4 can also be easily taken out from the mounting groove 3 of the solenoid 1.

[0024] In addition, the constriction 8 of the retaining spring reset mechanism of this embodiment can be replaced by series-connected balls. Example

[0025] A solenoid valve solenoid and shock absorber connection structure of a solenoid valve shock absorber, such as Figure 5 As shown, it includes a solenoid 1 and a solenoid valve gland 2, one end of the solenoid 1 is inserted into the solenoid valve gland 2, and sealing is achieved by a sealing ring 6. A rectangular mounting groove 3 is provided on the solenoid 1, and a retaining ring 4 is provided in the mounting groove 3. An inwardly protruding mounting snap ring 5 is provided on the inner side of the solenoid valve gland 2. The mounting snap ring 5 is located between the retaining ring 4 and the sealing ring 6 and is clamped on the outer side of the retaining ring 4. The retaining ring 4 is an open ring, and the end face of the retaining ring 4 is a right-angled trapezoid. The outer side surface of the retaining ring 4 is an inclined surface, and the outer diameter of the side facing the solenoid valve gland 2 is smaller than the outer diameter of the side facing away from the solenoid valve gland 2. Correspondingly, the inner side surface of the mounting snap ring 5 of the solenoid valve gland 2 is an inclined surface matched with the retaining ring 4, and the minimum inner diameter of the mounting snap ring 5 is smaller than the maximum outer diameter of the retaining ring 4, and the maximum inner diameter of the mounting snap ring 5 is larger than the minimum outer diameter of the retaining ring 4, so that when the retaining ring 4 falls into the inner side of the mounting snap ring 5, it can stably support the mounting snap ring 5 to avoid displacement.

[0026] This embodiment also includes a spring reset mechanism for assisting the spring 4 to escape. The spring reset mechanism is arranged on the solenoid 1 and includes an adjustment bolt 12 and a traction rope 11. Figure 6In the figure, the retaining spring 4 includes two symmetrically arranged half pieces, and buffer grooves 9 are opened at the centers of the two half pieces respectively corresponding to the mounting grooves 3. A compression spring 10 is arranged in the buffer groove 9 to support the retaining spring 4. An adjusting hole is opened on the spiral tube perpendicular to the plane where the retaining spring 4 is located, and the adjusting bolt 12 is inserted into the adjusting hole. A wire-passing channel is opened from the bottom of the adjusting hole to the two buffer grooves 9. The traction rope 11 is inserted into the wire-passing channel. One end of the traction rope 11 passes through the buffer groove 9 and the compression spring 10 and is connected to the retaining spring 4, and the other end is connected to the adjusting bolt 12 and is wound around the adjusting bolt 12 as the adjusting bolt 12 rotates. The lengths of the two wire-passing channels are consistent, the lengths of the two traction ropes 11 are consistent, and the distances between the adjusting bolt 12 and the two buffer grooves 9 are consistent.

[0027] like Figure 7 and 8 As shown, a through hole is opened at the position of the retaining spring 4 corresponding to the buffer groove 9, and a section of the through hole located on the outside of the retaining spring 4 is a countersunk hole 13, and a fastening bolt 15 is passed through the countersunk hole 13. A connecting block 14 is provided at the end of the traction rope 11 in the buffer groove 9, and the connecting block 14 is passed into the through hole from the inner side surface of the retaining spring 4, and the fastening bolt 15 is screwed to the connecting block 14.

[0028] Furthermore, a scale may be provided on the edge of the adjustment hole of the solenoid 1 to mark at least two lines, which respectively correspond to the outward support and the contraction of the clip 4 .

[0029] This embodiment is applied to the solenoid valve shock absorber. When it needs to be disassembled for maintenance, first rotate the adjusting bolt 12 and wrap the traction rope 11 around the adjusting bolt 12. As the traction rope 11 is pulled, the compression spring 10 is compressed and the retaining spring 4 contracts, so that the solenoid 1 can be pulled out and separated from the solenoid valve gland 2; then loosen the fastening bolt 15 to separate the retaining spring 4 from the connecting block 14, and the connecting block 14 and the compression spring 10 naturally fall into the mounting groove 3, and the retaining spring 4 is disassembled.

[0030] In summary, combined with the above-mentioned structure and working process, it can be found that the solenoid valve solenoid and shock absorber connection structure of the solenoid valve shock absorber proposed in this application can firmly realize the stable connection between the solenoid and the solenoid valve cover, is simple to operate, and can also be easily separated, with significant effect.
