Description

Technical Field

[0001] The invention relates to the technical field of insulating operating rods, in particular to an electric insulating operating rod. Background Art

[0002] The insulated operating rod is a tool used for live working. Its main function is to provide safe insulation protection for operators during the installation, inspection and maintenance of electrical equipment to avoid electric shock accidents. The insulated operating rod is generally composed of a working part, an insulating rod body and a hand-held part. The working part is usually a tool head such as a hook or a wrench made of metal, which is used to perform corresponding operations. The insulating rod body is usually assembled from multiple rods. The rod body is made of high-strength insulating materials such as epoxy resin, glass fiber, etc., which can effectively isolate the current. The hand-held part is generally made of plastic or rubber, which is convenient for operators to hold and also has certain insulation properties.

[0003] For example, the patent with announcement number CN217640823U discloses a sleeve-type combined insulating operating rod, which includes a first insulating rod, one end of which is fixedly connected to a fixed tube. The sleeve-type combined insulating operating rod is arranged by the coordination between the first insulating rod, the second insulating rod, the fixed tube, the push column, the fixed buckle plate, the support spring, the handle and the slot. When it is necessary to lower the first insulating rod to connect with the second insulating rod, the staff can press the handle by hand, and the handle will be driven to move after the force is applied to the handle, so that the fixed buckle plate moves to the middle of the fixed tube. At this time, the second insulating rod is directly inserted into the fixed tube, and the fixed buckle plate is directly inserted into the slot. Under the action of the support spring, the slot and the fixed buckle plate are fixed more firmly, so that the first insulating rod and the second insulating rod are not only firmly connected, but also save time and effort, greatly improving the installation efficiency.

[0004] The patent with announcement number CN213341048U discloses a foldable insulating operating rod, which includes at least two sections of insulating operating rods, which are rotatably connected by a rotating shaft. The insulating operating rod includes a rod body and a protrusion arranged at the end of the rod body, and the protrusions at the contact side ends of the two connected insulating operating rods are interlocked. The contact side ends of the two connected insulating operating rods are both provided with permanent magnets, and the permanent magnets on the contact sides of the two connected insulating operating rods have different magnetic properties. The same side of the two connected insulating operating rods is correspondingly provided with a buckle. The advantage of this utility model is that it avoids the problem that the segmented insulating operating rod is easy to fall from a high place during use, and improves the portability of the insulating operating rod.

[0005] In the prior art such as the above-mentioned patent, the insulating operating rod assembled from multiple sections is usually designed to be telescopic or foldable for easy carrying and storage. However, whether it is telescopic or foldable, especially the insulating operating rod with more than three sections, manual operation is usually required during the unfolding and storage process, and the ease of operation still needs to be improved.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-Figure 9 An electric insulating operating rod provided by an embodiment of the present invention comprises a plurality of coaxial sleeve rods 1 which are slidably sleeved with each other, a threaded sleeve 2 is arranged between two adjacent sleeve rods 1, the number of sleeve rods 1 is usually set to 3-5 sections, and the number of threaded sleeves 2 is one less than the number of sleeve rods 1. For two adjacent sleeve rods 1, an internal thread is provided on the inner wall of the sleeve rod 1 located on the outside, a first sliding groove is provided on the inner wall of the sleeve rod 1 located on the outside, and a first sliding edge is provided on the peripheral side surface of the sleeve rod 1 located on the inside, the first sliding edge and the first sliding groove are slidably matched, so that the two adjacent sleeve rods 1 can only slide relative to each other in the axial direction but cannot rotate relative to each other, an external thread is provided on the peripheral side surface of the corresponding threaded sleeve 2, and the threaded sleeve 2 is threadedly matched with the internal thread on the outer sleeve rod 1 through the external thread thereon, and although the first sliding groove cuts off the internal thread, it does not affect the threaded match between the threaded sleeve 2 and the internal thread.

[0032] For the threaded sleeve 2 arranged between two adjacent sleeve rods 1, the threaded sleeve 2 is coaxially connected to the bottom of the sleeve rod 1 located on the inner side, and is threadedly connected to the sleeve rod 1 located on the outer side. Specifically, the threaded sleeve 2 and the corresponding sleeve rod 1 are connected in rotation through a thrust ball bearing; each threaded sleeve 2 is coaxially connected to a slide bar 3 for sliding movement. Specifically, the threaded sleeve 2 and the corresponding slide bar 3 are connected in coaxial sliding movement through the cooperation between the second slide groove and the second slide edge that are mutually slidably connected. The length direction of the second slide edge and the second slide groove is the axial direction of the threaded sleeve 2. One is that the second slide groove is arranged on the peripheral side surface of the slide rod 3, and the second slide edge is arranged on the inner wall of the corresponding threaded sleeve 2. The other is that the second slide edge is arranged on the peripheral side surface of the slide rod 3, and the second slide groove is arranged on the inner wall of the corresponding threaded sleeve 2. A limiting structure is also arranged on the top of the second slide groove to prevent the threaded sleeve 2 from sliding upward and disengaging from the corresponding slide rod 3.

[0033] The two adjacent sliding rods 3 are coaxially slidably sleeved. Specifically, for the two adjacent sliding rods 3 that are slidably sleeved, a third slide groove is provided on the peripheral side surface of the inner sliding rod 3, and a third sliding edge is provided on the inner wall of the outer sliding rod 3. The third sliding edge is slidably matched with the corresponding third slide groove. There is a limiting structure between the third slide groove and the third slide edge. The third slide groove is not completely opened to the top of the inner sliding rod 3, so that the third sliding edge will abut against the solid top of the third slide groove and will not slide out of the third slide groove, that is, the outer sliding rod 3 will not be separated from the inner sliding rod 3. The third slide groove and the second slide groove of the same sliding rod 3 can be the same slide groove. The bottom of the outermost sleeve rod 1 is rotatably connected with a rotating disk 4. The sliding rod 3 (i.e., the innermost sliding rod 3) on the bottom threaded sleeve 2 is coaxially connected with the rotating disk 4 through a sliding card structure 9. The outermost sleeve rod 1 is provided with a driving motor 7 for driving the rotating disk 4 to rotate.

[0034] The bottom of the outermost sleeve rod 1 is detachably connected to a columnar shell 5, and a drive motor 7 is fixedly installed in the shell 5. The rotating shaft of the drive motor 7 is coaxially fixedly connected to the rotating disk 4. The drive motor 7 has the functions of forward and reverse rotation. The bottom of the shell 5 is detachably connected to an end cover 6. A battery 8 is arranged near the end cover 6 inside the shell 5. The battery 8 supplies power to the drive motor 7. The battery 8 is connected to the end cover 6 to facilitate the loading and unloading of the battery 8.

[0035] See also Figure 6 The sliding structure 9 in the above technical solution includes a sliding sleeve 91, a first elastic member and a second elastic member. The sliding sleeve 91 is coaxially slidably sleeved on the sliding rod 3 on the threaded sleeve 2 at the bottom. At least one latching tooth 92 is provided on the peripheral side surface of the sliding sleeve 91. The diagonal edges of the latching tooth 92 are chamfered respectively. Figure 8 At least one slot 93 is provided on the inner wall of the rotating disk 4. Fig. 9The matching states between the latch tooth 92 and the latch groove 93 include complete engagement, complete disengagement and partial engagement.

[0036] The process of the first elastic member restoring its deformation drives the latch tooth 92 to fully engage with the latch groove 93. Specifically, the first elastic member includes a tension spring 96 and a slide column 94 located in the cavity inside the slide rod 3 on the lowest threaded sleeve 2. The slide column 94 is connected to the cavity along the axial sliding of the corresponding slide rod 3. A wall hole is provided on the corresponding slide rod 3, and the inner and outer openings of the wall hole are rounded. The top of the slide column 94 is fixedly connected to the inner wall of the slide sleeve 91 by passing through a pull rope 95 on the wall hole of the corresponding slide rod 3. A groove 99 parallel to the axial direction for accommodating the pull rope 95 is provided on the inner wall of the slide sleeve 91 or the peripheral side surface of the corresponding slide rod 3. One end of the tension spring 96 is fixedly connected to the end cap 98 at the bottom of the corresponding slide rod 3, and the other end is fixedly connected to the slide column 94.

[0037] The process of the second elastic member recovering its deformation drives the sliding rod 3 on the lowest threaded sleeve 2 to move downward relative to the rotating disk 4. Specifically, the second elastic member includes a compression spring 97 that is slidably sleeved on the sliding rod 3 on the lowest threaded sleeve 2. The lower end of the compression spring 97 abuts against the bottom of the corresponding sliding rod 3, and the upper end abuts against the convex ring on the inner wall of the rotating disk 4.

[0038] The latching teeth 92 and the latching slot 93 are fully engaged, that is, the latching teeth 92 and the latching slot 93 are relatively stationary and can move synchronously, and the rotating disk 4 can drive the sliding sleeve 91 to rotate together; the latching teeth 92 and the latching slot 93 are completely disengaged, that is, the latching teeth 92 and the latching slot 93 are separated, and the rotating disk 4 cannot drive the sliding sleeve 91 to rotate; there are two cases of partial engagement: one is that the lower part of the latching teeth 92 is located in the latching slot 93, when the rotating disk 4 rotates forward, the chamfer on the lower part of the latching teeth 92 abuts against the latching slot 93 so that it can slide and completely disengage from the latching slot 93, and the rotating disk 4 can no longer drive the sliding sleeve 91 to rotate forward, and when the rotating disk 4 reverses, the straight line of the lower part of the latching teeth 92 The angle abuts against the slot 93 so that it will not slide relative to the slot 93 and will not disengage from the slot 93, and the rotating disk 4 can drive the sliding sleeve 91 to reverse; the other is that the upper part of the latch tooth 92 is located in the slot 93, and when the rotating disk 4 reverses, the chamfer on the upper part of the latch tooth 92 abuts against the slot 93 so that it can slide and completely disengage from the slot 93, and the rotating disk 4 can no longer drive the sliding sleeve 91 to reverse; when the rotating disk 4 rotates forward, the right angle of the upper part of the latch tooth 92 abuts against the slot 93 so that it will not slide relative to the slot 93 and will not disengage from the slot 93, and the rotating disk 4 can drive the sliding sleeve 91 to rotate forward.

[0039] The function of the sliding structure 9 is to enable the sliding sleeve 91 to disengage from the rotating disk 4 when each sleeve rod 1 is extended to the maximum limit and when each sleeve rod 1 is contracted to the maximum limit, thereby avoiding overload damage to the drive motor 7, and to enable each sleeve to be contracted smoothly after being extended to the maximum limit, and to enable each sleeve rod 1 to be extended smoothly after being contracted to the maximum limit.

[0040] In the present invention, the driving motor 7 drives the rotating disk 4 to rotate, and the rotating disk 4 drives the corresponding innermost sliding rod 3 to rotate through the sliding structure 9, and the sliding rod 3 drives the corresponding threaded sleeve 2 to rotate and the other sliding rods 3 to rotate, so that each threaded sleeve 2 is threadedly matched with the corresponding outer sleeve rod 1, thereby driving the corresponding inner sleeve rod 1 to extend or contract relative to the outer sleeve rod 1, realizing the electric extension and retraction of each sleeve rod 1. During this period, the latching teeth 92 on the sliding sleeve 91 and the latching grooves 93 on the rotating disk 4 are in a fully engaged state.

[0041] When each sleeve rod 1 is about to be extended to the maximum limit, the distance between adjacent slide bars 3 is also extended to the maximum limit. Continuing to drive the rotating disk 4 to rotate will cause each slide bar 3 and each threaded sleeve 2 to continue to rotate. The threaded sleeve 2 is spirally advanced on the corresponding sleeve, which will pull the innermost slide bar 3 upward. Due to the elastic force of the first elastic member, the innermost slide bar 3 will move upward with the sliding sleeve 91 and the latch tooth 92, so that the sliding sleeve 91 and the rotating disk 4 are axially displaced upward, and the lower part of the latch tooth 92 is partially engaged with the latch groove 93. If the rotating disk 4 continues to rotate, the chamfer of the lower part of the latch tooth 92 will abut against the latch groove 93, thereby overcoming the elastic force of the tension spring 96 and causing the latch tooth 92 to When the locking cam 92 is in the state of being stretched, the locking cam 92 is engaged with the locking cam 93 and the locking cam 92 is engaged with the locking cam 93. ...

[0042] When each sleeve rod 1 needs to be retracted after being extended to the maximum limit, the "retract" button of the control drive motor 7 is pressed, which changes the rotation direction of the drive motor 7. The right angle of the lower part of the latch tooth 92 abuts against the latch groove 93, so that it will not slide relative to the latch groove 93 and disengage from the latch groove 93. The rotating disk 4 drives the sliding sleeve 91 to rotate, and the sliding sleeve 91 drives each slide rod 3 to rotate, so that each slide sleeve 91 can be retracted, and the elastic force of the compression elastic force causes the innermost slide rod 3 to slide down a short distance relative to the sliding sleeve 91, so that the latch tooth 92 and the latch groove 93 can be completely engaged.

[0043] When each sleeve rod 1 is about to shrink to the maximum limit, the adjacent sliding rods 3 are also shrunk to the maximum limit. Continuing to drive the rotating disk 4 to rotate will cause each sliding rod 3 and each threaded sleeve 2 to continue to rotate, and the threaded sleeve 2 will spirally retreat on the corresponding sleeve, and the bottom of the lowest threaded sleeve 2 will abut against the abutment ring 910 on the sliding sleeve 91, so that the sliding sleeve 91 and the rotating disk 4 will be axially displaced downward, and the upper part of the latch tooth 92 will be partially engaged with the latch groove 93. If the rotating disk 4 continues to rotate, the chamfer of the upper part of the latch tooth 92 will abut against the latch groove 93, thereby overcoming the elastic force of the tension spring 96 and causing the latch tooth 92 to slip out of the latch groove 93. The disk 4 will then idle, that is, it will not drive the sliding sleeve 91 and the sliding rods 3 to rotate, and the sleeve rods 1 will remain at the maximum contraction limit and will not continue to contract, thereby avoiding overloading of the drive motor 7. When the slot 93 on the idling rotating disk 4 is aligned with the tooth 92 again, the elastic force of the tension spring 96 will make the tooth 92 enter the slot 93 again, and then the chamfered corner of the upper part of the tooth 92 will abut against the slot 93 again and slip out of the slot 93. This cycle will cause a rhythmic "clicking" sound to occur between the tooth 92 and the slot 93, and the operator will know that it has been contracted into place and can release the "contraction" button that controls the drive motor 7.

[0044] When each sleeve rod 1 needs to be extended after being retracted to the maximum limit, the "extend" button that controls the drive motor 7 is pressed, which changes the rotation direction of the drive motor 7 again. The right angle of the upper part of the latch tooth 92 abuts against the latch groove 93, so that it will not slide relative to the latch groove 93 and detach from the latch groove 93. The rotating disk 4 drives the sliding sleeve 91 to rotate, and the sliding sleeve 91 drives each slide rod 3 to rotate, so that each sliding sleeve 91 can be extended.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
