The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Example 1
As shown in fig. 1 and 2, the auxiliary cable laying probe of this embodiment includes a probe body 1, the front end of the probe body 1 is provided with a tip 16, a threaded hole 4 is provided on one side of the rear end face of the probe body 1, a socket 7 is provided on the other side of the rear end face of the probe body 1, an inner cavity is provided on one side of the socket 7 facing the front end of the probe body 1, a pressing block 9 is slidingly connected to the rear part of the inner cavity in a transverse direction (i.e. the left-right direction of the probe), an insert 13 is slidingly connected to the front part of the inner cavity in a longitudinal direction (i.e. the front-rear direction of the probe), the insert 13 has an inclined surface 2 abutting against the bottom surface of the pressing block 9, a stud 12 is connected to the probe body 1 in a rotating manner along a longitudinal thread, a pressing nut 15 is fixedly connected to the stud 12, a pressing nut groove 14 is provided on the probe body 1, and the pressing nut 15 is located in the pressing nut groove 14.
When the probe is used, the probe rod is connected with the probe rod through the threaded hole 4, a cable is inserted into the socket 7, then the stud 12 drives the pressing block 9 to longitudinally move by rotating the compression nut 15 through the tool wrench, and the inclined surface 2 presses the inserting block 13 to transversely move due to the abutting of the inclined surface 2 and the inserting block 13, so that the gap between the inserting block 13 and the inner cavity is changed, and the cable in the inserting block is pressed tightly.
As one side of the rear end face of the probe is connected with the probe rod and the other side of the probe clamps the cable, the whole structure is flat and compact, and the probe is beneficial to advancing in a narrow space. The head end of the probe is provided with the tip 16, so that the probe can smoothly pass through a disordered cable trench, the tip 16 at the front end is open, a cable at the rear end is immediately connected, the situation that the cable head end is blocked by foreign matters is avoided, no protruding part exists on the probe, even if a compression nut 15 for compression is also hidden in the compression nut groove 14, the phenomenon that the whole set of probing device is blocked by accident is avoided, and the overall operation efficiency is improved.
Specifically, the compression nut groove 14 of the present embodiment is located in front of the inner chamber, and the middle partition 11 is fixedly disposed in the inner chamber, so that the inner chamber is divided into the upper chamber 3 and the lower chamber 5, the insert 13 is located in the upper chamber 3, and the press block 9 is located in the lower chamber 5. One end of the stud 12 is rotatably connected with the front side wall of the compression nut groove 14, then the stud 12 penetrates through the rear side wall of the compression nut groove 14 and the front side wall of the upper chamber 3, and finally the other end of the stud 12 is rotatably connected with the middle partition plate 11.
Because the insertion block 13 can bear transverse extrusion component force when pressing the pressing block 9, the stud 12 can also receive the lateral component force, and the front end and the rear end of the stud 12 are supported by arranging the middle partition plate 11, so that the running stability of the stud 12 is improved, and the service life of equipment is prolonged.
In addition, in this embodiment, the middle partition 11 is fixedly connected with the inner side wall and the outer side wall of the inner chamber (as shown in fig. 1), and a side interval is disposed between the middle partition 11 and the two side walls of the inner chamber (i.e., the left and right side walls shown in fig. 2), as shown in fig. 2. The inserting block 13 is U-shaped, the bottom edge of the U-shaped of the inserting block 13 is in threaded connection with the stud 12, inclined surfaces 2 are arranged on the two side edges of the U-shaped of the inserting block 13, penetrate through the two side intervals in a one-to-one correspondence mode, and then are abutted to the bottom surface of the pressing block 9.
Because the insert 13 eventually passes over the middle partition 11 from the upper chamber 3 to the lower chamber 5 to act on the press block 9, and the inclined surface 2 passes through the middle partition 11 more widely, if the insert 13 adopts a general solid triangular block structure, the middle partition 11 is more and more occupied in space during the pressing down of the insert 13, so that the support stud 12 cannot be removed, or the structure of the insert is unstable and is easy to break. After the structure is adopted, the partition plate 11 is firmly connected with the probe main body 1 in the main stress direction of the stud 12 (namely, the left-right direction of fig. 1), so that the stress stability of the probe main body is ensured, and effective strong support is provided for the stud 12. While its two lateral openings allow the passage of the U-shaped insert 13 to function. The whole structure is reasonable and compact and is not excessively complex.
As also shown in fig. 2, the width between the two side walls of the inner chamber of this embodiment is greater than the width of the socket 7, so that a shoulder 8 is formed at the corner of the inner chamber; the press block 9 abuts between the middle partition 11 and the shoulder 8 so as to form a sliding connection.
The structure utilizes the characteristic that the middle partition plate 11 can serve as a slideway, and the position of the pressing block 9 can be effectively fixed in the front-back direction only by arranging the matched shoulder 8 at the socket 7 on the opposite side, and the pressing block 9 can transversely slide in the slideway formed by the middle partition plate 11 and the shoulder 8. The structure is simple, effective, reasonable and compact, and no additional slideway structure is added, so that the manufacturing cost is reduced, the equipment volume is reduced, and the probe can pass through a narrow space.
In addition, in the embodiment, the two sides of the bottom surface of the pressing block 9 are provided with matching inclined surfaces 10 which are matched with the inclined surfaces 2. This prevents the problem of inaccurate positioning and rattling of the pressing due to the abrasion of the sides of the press block 9.
In addition, the inclined surface 2 of the embodiment is inclined towards the inner side of the probe body 1, so that the pressing block 9 can be extruded from the outer side to the inner side, the cable is extruded to be closer to the probe rod, the gap between the probe rod and the cable is reduced, the whole is as compact as possible, and the problem of increasing friction resistance due to the large whole width when the cable passes through a narrow space is avoided. The embodiment is also provided with a spring 6 between the press block 9 and the inner chamber, which makes the press block 9 slide outwards, so that the press block 9 returns to the original position when being released.
The tip of the tip 16 is located at the midline of the tip 16 and is provided as a rounded corner 17. The provision of the rounded corners 17 prevents penetration of the other cable sheath during the passage, while the centering arrangement prevents the probe from becoming more and more deflected during the passage.
Example 2
As shown in fig. 3 and 4, this embodiment is substantially the same as the previous embodiment, except that a pressing block groove 19 with an arc-shaped cross section is provided in the middle of the top surface of the pressing block 9 along the front-rear direction, a fixing groove 20 with an arc-shaped cross section and adapted to the pressing block groove 19 is provided on the inner side wall of the inner chamber, and anti-slip ribs 18 are provided in both the pressing block groove 19 and the fixing groove 20.
After the arrangement, compared with the use of a plane extrusion cable, the arc-shaped groove can be more attached to the outer side of the cable, so that the cable skin is prevented from being excessively extruded and damaged, and the situation that the cable is pulled out in the process of passing is also reduced by the aid of the anti-slip ribs 18.
Example 3
As shown in fig. 5 and 6, this embodiment is substantially the same as the previous embodiment, except that a swinging plate groove 23 is provided in the middle of the arc-shaped section of the pressing block groove 19 along the front-rear direction, a swinging plate 22 is rotatably connected to the rear end of the swinging plate groove 23, the free end of the swinging plate 22 faces the front end of the probe body 1, a torsion spring is provided between the swinging plate 22 and the pressing block 9, the free end of the swinging plate 22 abuts against the inner side wall of the inner chamber under the action of the torsion spring, the swinging plate 22 is made of iron, and a magnetic switch 21 matched with the swinging plate 22 is provided on the inner side wall of the inner chamber.
Because the cable receives side object frictional force effect in the visit income in-process, produces the phenomenon of deviating from among the clamping device easily, if the cable deviate from after not in time being found, and visit the operation still go on, just find the cable and deviate from when the probe passes through difficultly and expose from the cable pit other end at last, can cause the very big waste of operating time. After the arrangement, when the cable is plugged into the jack 7, because of the inclined posture of the swinging plate 22, the cable can downwards press the swinging plate 22 to enter the swinging plate groove 23, so that the swinging plate 22 is separated from the magnetic switch 21, and when the cable is separated, the swinging plate 22 can be switched on the magnetic switch 21 again under the action of the torsion spring, so that the cable can be timely found to be separated, and the waste of working hours is avoided. In addition, the swinging plate 22 is arranged in the middle of the pressing block groove 19, and the arc-shaped groove can be utilized to automatically and centrally press the cable in the process of pressing the cable, so that the swinging plate 22 can be effectively and reliably pressed down. And after being pressed down, the swinging plate 22 protruding out of the pressing block groove 19 is prevented from damaging the cable sheath, and then the swinging plate groove 23 is arranged for accommodating the cable sheath.
Example 4
As shown in fig. 7, this embodiment is substantially the same as the previous embodiment, except that a blind hole 24 is formed in the rear end face of the probe body 1, a coupling nut groove 25 perpendicular to the axis of the blind hole 24 is formed in the side wall of the probe body 1, the coupling nut groove 25 intersects with the blind hole 24 at the rear of the blind hole 24, a coupling nut 26 is provided at the intersection of the coupling nut groove 25 and the blind hole 24, the coupling nut 26 is rotatably connected with the blind hole 24 through a boss 27, and a threaded hole 4 is provided along the axis.
Because the probe body 1 is flat, and when the probe body protrudes from the cable trench, the posture of the probe body does not necessarily meet the cable-releasing form, for example, when the cable is just below when the probe body protrudes and other cables are extruded around, the probe body should be integrally detached and the cable is released again, but in the previous embodiment, the probe body can only be detached by rotating the probe rod, but most of the probe rod is in the cable trench which is crowded in disorder, and the rotation is very laborious, so that the requirements of complaints cannot be better met. In this embodiment, the rotating coupling nut 26 replaces the previously fixed threaded hole, so that the probe rod can be detached by rotating the coupling nut 26 while keeping the probe body 1 stationary.
Finally, it is emphasized again that the embodiments described herein are merely some, but not all, embodiments of the utility model, and that the specific embodiments described herein are merely illustrative of the utility model, not limiting of the utility model to the claims. Any obvious modifications which are made by those skilled in the art under the design concept of the present utility model are within the scope of the present utility model based on the embodiments of the present utility model.
In addition, the technical scheme of the application has been subjected to pilot-scale experiments, namely small-scale experiments of products before large-scale mass production; after the pilot test is completed, the use investigation of the user is performed in a small range, and the investigation result shows that the user satisfaction is higher; now, the preparation of the formal production of the product for industrialization (including intellectual property risk early warning investigation) is started.
