Detailed Description
The invention is further illustrated by the following specific examples:
as shown in fig. 1, a flexible shaft assembly includes a cable core 100, a push-pull rod 200, a quick connector 300 and a tube 400.
The cable core 100 is inserted into the pipe body 400 and can reciprocate in the pipe body 400, two ends of the cable core 100 are respectively connected with the push-pull rods 200, and the push-pull rods 200 at the two ends are respectively connected with the quick connectors 300 located outside the pipe body 400.
Referring to fig. 1 and 2, the pipe body 400 includes a sleeve 410, a metal casing joint 420, and a plastic guide pipe 440.
The sheath joints 420 are fixed to both ends of the casing 410, and the guide pipe 440 is inserted into the sheath joints 420. Both ends of the push-pull rod 200 are passed through the guide tube 440 and connected to the quick coupling 300 located at the outside.
The push-pull rod 200 includes a thick section 210 connected to the quick connector 300 and a thin section 220 connected to the cable core 100, the thin section 220 extending into the guide tube 440 and being connected to the end of the cable core 100 located in the guide tube 440. The outer diameter of the thick section 210 is larger than the inner diameter of the guide tube 440. When the push-pull rod 200 is operated to the end of the stroke, the thick section 210 can abut against the outer end surface of the guide pipe 440, so that the limit is realized.
Referring to fig. 3 and 5, a guide tube 450 made of plastic is disposed in the guide tube 440, the guide tube 450 is inserted between the thin section of the push-pull rod 200 and the guide tube 440, and the diameter of the cable core 100 is smaller than the inner diameter of the guide tube 440. The guide liner 450 serves to fill the gap between the push-pull rod 200 and the guide tube 440, reduce drag, and prevent wear of the guide tube 440.
The outer wall of the guide liner tube 450 is circumferentially provided with a plurality of cylindrical bosses 451, and the bosses 451 are embedded into grooves in the inner wall of the guide tube 440, so that the guide liner tube 450 is limited, and the guide liner tube 450 is prevented from axially moving.
Since the push-pull rod 200 of the present invention is divided into the thick section 210 and the thin section 220, and the section connecting the cable core 100 is the thin section 220, the difference between the outer diameters of the push-pull rod 200 and the cable core 100 is smaller than that of the prior art, that is, the cable core 100 and the guide liner 450 can have a smaller gap. Therefore, the bending amplitude of the cable core 100 generated when the cable core is pushed forwards is smaller, the cable core 100 is not easy to damage, and the service life and the strength of the cable core 100 are greatly prolonged.
In addition, by adopting the structure, the gap between the cable core 100 and the guide liner tube 450 is not required to be filled in by thickening the cable core 100, the use requirement can be met by using a thinner cable core, the cost is reduced, the flexible shaft is softer, and the installation is more convenient.
Since the push-pull rod 200 is divided into a thick section and a thin section, the guide liner 450 cannot be directly sleeved on the push-pull rod 200 during assembly, the push-pull rod 200 has the structure shown in fig. 5, and is composed of two half pipes 452 movably connected, and the two half pipes 452 are fitted on the thin section of the push-pull rod 200 during use, so that the installation can be completed.
As shown in fig. 3, the pipe joint 420 has a hollow circular pipe shape, and has an assembly chamber 421 at an outer end and a through hole 422 extending from the assembly chamber 421 at the outer end to an inner end. The inner diameter of the fitting chamber 421 is decreased stepwise from the outside to the inside.
With reference to fig. 3 and 6, the innermost end of the assembly cavity 421 is provided with a limiting liner tube 430, the outer wall of the limiting liner tube 430 is matched with the assembly cavity 421 in shape, the outer wall of the limiting liner tube 430 is provided with a circle of convex ring 433, and the inner wall of the assembly cavity 421 is provided with an annular groove 423. The bead 433 of the restraining liner 430 snaps into the annular groove 423, thereby securing the restraining liner 430 into the assembly chamber 421. The width of the annular groove 423 is slightly greater than the width of the collar 433 to facilitate installation of the position limiting liner 430.
The limiting liner 430 comprises a ball socket part 431 and a neck part 432 with the inner diameter smaller than that of the ball socket part 431, a ball head 446 matched with the ball socket part 431 is arranged on the outer wall of the end part of the guide tube 440, and the ball head 446 of the guide tube 440 is movably arranged in the ball socket part 431. Allowing the guide tube 440 to swing at a swing angle with respect to the service coupling 420. The assembly cavity 421 with the inner diameter decreasing from outside to inside can reserve enough space for the swing of the guide tube 440, and avoid the guide tube 440 from rubbing against the inner wall of the protection tube joint 420 to cause abrasion.
When the push-pull rod 200 in the guide pipe 440 runs to the stroke end position, the push-pull rod can extend into the limiting liner pipe 430 and abut against the neck 432 of the limiting liner pipe 430, so that limiting is realized, and noise generated by collision of the push-pull rod 200 and the protective pipe joint 420 which is made of metal is avoided.
Meanwhile, as the push-pull rod 200 can directly extend into the limiting liner tube 430, compared with the existing structure that the push-pull rod 200 is stopped at the end surface of the limiting liner tube 430, the limit liner tube has a larger stroke range, and can ensure enough stroke under the use condition that the vehicle installation space is narrow and the installation distance is smaller, so that the limit liner tube has better applicability compared with the prior art.
Four axial grooves 434 are uniformly distributed on the socket of the ball socket portion 431 of the limiting liner tube 430 along the circumferential direction, so that the limiting liner tube 430 can be more conveniently installed in the protective tube joint 420 by adopting the structure, and the limiting liner tube 430 is not easily damaged.
Referring to fig. 2 and 4, an annular cavity 441 is formed on an inner wall of an outer end (i.e., an end close to the quick coupling) of the guide tube 440, and a sealing ring 443 is disposed in the annular cavity 441. The outer wall of the guide tube 440 is provided with an annular protrusion 442 at a position corresponding to the annular recess 441. The annular protrusion 442 is provided to improve the overall structural strength of the guide tube 440 and to enable the use of an annular cavity 441 having a greater depth to accommodate the sealing ring 423.
Through locating sealing washer 423 in the stand pipe 440, can avoid sealing washer 423 to expose in external environment, slow down sealing washer 423's ageing speed, improve life.
The inner wall of the sealing ring 423 is provided with a plurality of sealing protrusions 444 that are in sealing contact with the push-pull rod 200 along the axial direction, and the axial cross section of the sealing protrusions 444 is in a saw-tooth shape that is inclined toward the quick coupling 300 (i.e., toward the outside of the guide tube), and the end of the sealing protrusions that is in contact with the push-pull rod 200 forms an acute angle.
Plural in this context means two and more. The number of the sealing protrusions 444 in this embodiment is three, and the sealing performance and the service life can be effectively improved by using a plurality of sealing protrusions 444.
The use of the serrated sealing protrusions 444 can reduce the contact area between the sealing ring 443 and the push-pull rod 200, reduce the running resistance, and improve the transmission efficiency. And can adopt bigger interference fit volume, improve sealing performance.
The provision of the sealing protrusion 444 in a shape of a slanted serration can prevent water from penetrating into the guide tube to further improve the waterproof performance.
To avoid the situation where the sealing ring 443 is installed reversely, the sealing protrusion 444 is inclined inward to cause the water-proof failure. Preferably, the seal 443 is provided with an error prevention structure, which is an error prevention step 445 provided on the outer peripheral surface of one end of the seal 443. By adopting the structure, the sealing ring 443 cannot be installed in the annular concave cavity 441 when the installation direction is wrong, and the problem of water-proof failure caused by reverse installation of the sealing ring 443 is effectively avoided.
Of course, other anti-misassembly structures may be used, such as ribs, chamfers, etc. on the outer wall of the seal ring. Alternatively, instead of providing the error protection, it is also possible to provide error protection marks, such as an indicator arrow, on the outer wall of the sealing ring.
As shown in fig. 3, a corrugated sealing sleeve 424 in sealing contact with the guiding tube 440 is disposed at an end of the protecting tube joint 420 to prevent external moisture and dust from invading into the flexible shaft assembly, thereby improving the overall protection level of the flexible shaft assembly.
Referring to fig. 1, the service coupling of the present invention includes a first service coupling 425 at one end and a second service coupling 426 at the other end. The first and second service couplings 425, 426 are generally identical in construction, differing only in that the first service coupling 425 has a mounting flange 427 on an outer wall thereof, and the second service coupling 426 has a mounting groove 428 on an outer wall thereof. Obviously, it is also possible to use a uniformly shaped casing joint depending on the actual situation.
