Description

Technical Field

[0001] This invention relates to the field of electrical operating equipment, specifically to an auxiliary operating lever for a drawer switch operating handle. Background Technology

[0002] Drawer switches, also known as drawer-type switch cabinets, typically refer to closed enclosures made of steel plates. The electrical components of the incoming and outgoing circuits are installed in removable drawers, forming functional units that can complete a certain type of power supply task. They are separated from the busbars or cables by grounded metal or plastic functional plates, forming three areas: busbars, functional units, and cables. Isolation measures are set between each functional unit, thus ensuring that the drawer switches have high reliability, safety, and interchangeability during use. They are now widely used in environments with high power supply requirements, such as industrial and mining enterprises and high-rise buildings.

[0003] In recent years, with the expansion of the application range of drawer switches, the defects in their own hardware structure have also been exposed. Taking the operating handle of a drawer switch as an example, its structural design is relatively simple and the resistance during the turning process is relatively large. When engineers are debugging or installing several drawer switches, they often have to spend a lot of physical strength due to the reciprocating turning and adjustment of multiple operating handles, and the corresponding work efficiency will decrease. Although some auxiliary operating devices have appeared on the market, such as electric switches and push-pull switches, these auxiliary operating devices often have problems such as complex structure, inconvenience of use, and easy damage.

[0033] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-9 An auxiliary operating lever for a drawer switch handle includes a hollow connecting rod 1. A rod body assembly 2 and a connecting cylinder 3 are respectively provided at both ends of the hollow connecting rod 1. One end of the connecting cylinder 3 has a semi-open space that can be fitted with the drawer switch handle. The rod body assembly 2 can slide and adjust on the surface of the hollow connecting rod 1 and self-press to limit its position. The rod body assembly 2 includes a main hollow rod 21 that is snapped onto the surface of one end of the hollow connecting rod 1. Several elastic clamping blocks 23 are arranged circumferentially on the end face of one end of the main hollow rod 21. A first external thread is formed on the surface of one end of the main hollow rod 21, and an internally threaded top cylinder 24 is connected to it through the first external thread. During the helical engagement with the main hollow rod 21, the internally threaded top cylinder 24 can synchronously press against the surfaces of the elastic clamping blocks 23, causing the elastic clamping blocks 23 to deform and press against the surface of one end of the hollow connecting rod 1 for limitation.

[0035] In use, the rod assembly 2, connecting cylinder 3, and connecting cylinder 3 can be made of lightweight materials such as aluminum alloy or plastic to reduce the overall weight. The semi-open space inside the connecting cylinder 3 is fitted and snapped into the existing drawer switch operating handle. This utilizes the auxiliary operating rod formed by the rod assembly 2, hollow connecting rod 1, and connecting cylinder 3 to increase the rotational lever arm of the drawer switch operating handle. Subsequently, by holding the rod assembly 2, the connecting cylinder 3, hollow connecting rod 1, and drawer switch operating handle can be rotated and adjusted. Only a small force is needed to complete the rotation of the operating handle to a specified angle, reducing hand fatigue and solving the problem of excessive physical exertion caused by the reciprocating opening and closing of the operating handle during the debugging or installation process in existing technologies, thus maintaining the work efficiency of engineers during the debugging or installation process.

[0036] like Figure 1 , Figure 6 The surface of the other end of the main hollow rod 21 is provided with anti-slip texture to increase the friction between the palm and the main hollow rod 21 during subsequent gripping, achieving a stable and comfortable grip. The inner wall of one end of the main hollow rod 21 is provided with an annular groove that can accommodate one end of the internal threaded top cylinder 24. Several friction strips are arranged along the circumference of the surface of the middle part of the internal threaded top cylinder 24. There is a clearance between the elastic clamping blocks 23 in adjacent positions, and the inner wall of the elastic clamping block 23 that is in contact with the surface of the hollow connecting rod 1 is provided with friction texture, which increases the friction between the elastic clamping block 23 and the hollow connecting rod 1.

[0037] When in use, when it is necessary to adjust the combined length of the hollow connecting rod 1 and the rod assembly 2, the internal threaded top cylinder 24 is turned to rotate away from the hollow connecting rod 1. One end of the internal threaded top cylinder 24 is gradually retracted into the annular groove. At the same time, multiple elastic clamping blocks 23 automatically and elastically reset after being squeezed by the internal threaded top cylinder 24. The inner walls of multiple elastic clamping blocks 23 are all away from the hollow connecting rod 1.

[0038] Push the entire rod assembly 2 until the connection length between the rod assembly 2 and the hollow connecting rod 1 meets the usage requirements. Then, reset and rotate the internal threaded top cylinder 24 so that the internal threaded top cylinder 24 can synchronously press the surface of several elastic clamping blocks 23 during the spiral engagement with the main hollow rod 21. Then, the elastic clamping block 23 deforms and presses against the surface of one end of the hollow connecting rod 1 for limiting, thereby restoring the stability and reliability of the connection between the rod assembly 2 and the hollow connecting rod 1.

[0039] like Figure 1 , Figure 5 , Figure 8 The surface of the other end of the hollow connecting rod 1 is provided with a second external thread. One end of the connecting cylinder 3 is fixedly fitted with an internal threaded cylinder that can be threadedly connected to the other end of the hollow connecting rod 1. A limiting block is fixed on the end surface of the other end of the hollow connecting rod 1, and a buffer pad ring 7 is fixed on the other end of the connecting cylinder 3.

[0040] In use, considering the needs of connecting cylinder 3 in conjunction with drawer switch handle sets of different specifications, this application allows for adaptive adjustment of the semi-open space inside connecting cylinder 3. The specific operation is as follows:

[0041] Twisting the connecting cylinder 3 allows it to rotate forward or backward on the other end of the hollow connecting rod 1 under the support of the hollow connecting rod 1. This adjusts the fitting depth of the semi-open space inside the connecting cylinder 3. During the fitting process of the connecting cylinder 3 and the drawer switch handle, the buffer ring 7 can cushion the fitting operation of the connecting cylinder 3 and avoid hard impact.

[0042] like Figures 1-3 The surface of the connecting cylinder 3 is provided with a fixing component 4, which includes a fixing sleeve 41 and a limiting band 42. The fixing sleeve 41 has two pins in opposite positions. The two ends of the limiting band 42 are fixedly wrapped around the surfaces of the two pins and form a U-shaped structure. The middle of the U-shaped limiting band 42 is fitted with a clamping ring component 43. The clamping ring component 43 includes an elastic ring plate fitted on the outer side of the middle of the clamping ring component 43. The middle of the elastic ring plate is fitted with a guide shaft that passes through the middle space of the limiting band 42. Pressure plates are fitted inside the top and bottom of the elastic ring plate.

[0043] When using it, considering the continuous and stable use after the connecting cylinder 3 and the drawer switch operating handle are assembled, before assembling the connecting cylinder 3 and the drawer switch operating handle, the fixing part 4 and the drawer switch operating handle are first fitted and limited. The specific operation is as follows:

[0044] Bring the connecting cylinder 3 close to the drawer switch handle but do not fit them together. Then, extend the fold inside the limiting band 42 and fit it onto the structure of the drawer switch handle near the drawer switch surface. Next, fit the connecting cylinder 3 onto the drawer switch handle. After completion, press and push the clamping ring component 43 to forcibly tighten the fitting structure of the limiting band 42 and the drawer switch handle, thereby ensuring the continuous stability of the fitting of the connecting cylinder 3 and the drawer switch handle.

[0045] like Figures 1-3 The inner wall of the semi-open space of the connecting cylinder 3 is equipped with several auxiliary sealing rings 6, and the wall thickness of the auxiliary sealing rings 6 gradually decreases. The main hollow rod body 21 is internally fixedly fitted with an auxiliary conduit 22 that can be snapped into the interior of the hollow connecting rod 1. The other end of the main hollow rod body 21 is internally fitted with an anti-detachment component 5.

[0046] The inner wall of the other end of the main hollow rod 21 is provided with internal threads. The anti-detachment component 5 includes a conical anti-detachment block 51. One end of the conical anti-detachment block 51 can be threaded to the inside of the other end of the main hollow rod 21. The inside of the conical anti-detachment block 51 is provided with several through-hole adjustment holes 52. The end of the other end of the conical anti-detachment block 51 is provided with a support ring groove that communicates with the space of the adjustment holes 52. The inside of the support ring groove is fitted with an auxiliary frame plate 53 through a bearing. The auxiliary frame plate 53 can cover and close or rotate to make way for several adjustment holes 52 under the rotational support of the bearing. A rubber ring is fixed on the surface of the auxiliary frame plate 53. The surface of the rubber ring is tightly fitted with the inner wall of the outer ring of the support ring groove, thereby improving the stability of the auxiliary frame plate 53 after the rotational adjustment of the support ring groove stops.

[0047] During use, considering the short-term stable use requirement after the connecting cylinder 3 and the drawer switch handle are assembled, the anti-detachment component 5 is used to assist in meeting this requirement. The specific operation is as follows:

[0048] First, rotate the auxiliary frame plate 53 to cover and seal the several adjustment holes 52. Then, fit the connecting cylinder 3 with the drawer switch operating handle. During the fitting process, several auxiliary sealing rings 6 with different wall thicknesses will gradually increase the fitting connection strength and sealing effect between the connecting cylinder 3 and the drawer switch operating handle. After the connecting cylinder 3 is fitted, it will also relatively seal the internal space of the auxiliary operating rod. Thus, the air pressure difference between the inside of the auxiliary operating rod and the use environment is used to fully enhance the fitting connection strength between the connecting cylinder 3 and the drawer switch operating handle.

[0049] When it is necessary to disassemble the connecting cylinder 3 and the drawer switch operating handle, simply twist the auxiliary frame plate 53 to rotate and make room for several adjustment holes 52, which will break the sealing effect of the internal space of the auxiliary operating rod and restore the convenience and flexibility of disassembly.

[0050] like Figures 10-12 The other end of the main hollow rod 21 can also be equipped with a vacuum cleaning component. The vacuum cleaning component includes an auxiliary cylinder 8, a filter component 9, an air pump 10, and a control component 11. The filter component 9 is fitted inside one end of the auxiliary cylinder 8, and the other end of the auxiliary cylinder 8 can be threaded to the inside of the other end of the main hollow rod 21. An air guide ring groove 12 is opened on the inner wall of the auxiliary cylinder 8. The air pump 10 is fitted inside the auxiliary cylinder 8, and the output end of the air pump 10 is fitted inside the air guide ring groove 12. The control component 11 includes a protective shell, a switch, and a battery module. The protective shell is fixed on the surface of the auxiliary cylinder 8, and the switch and battery module are both fitted inside the protective shell and are electrically connected to the air pump 10 through wires.

[0051] The inner wall of one end of the auxiliary cylinder 8 is provided with a third external thread. The filter component 9 includes a support cylinder 91 and a filter screen plate 92. The filter screen plate 92 is fixedly fitted inside the end of one end of the support cylinder 91. The other end of the support cylinder 91 is threaded to the inside of one end of the auxiliary cylinder 8. A T-shaped rod 93 is fitted in the middle of the filter screen plate 92 through a bearing. One end of the T-shaped rod 93 extends into the inside of the support cylinder 91 and is fixed with a scraper 94 that can fit against one side surface of the filter screen plate 92.

[0052] When in use, considering the need for regular maintenance and cleaning of the drawer switch and the internal space characteristics of the auxiliary operating lever provided in this application, the cleaning of dust in the gap between the drawer switch operating handle and the drawer switch and the dust attached to the operating handle can be achieved by using a vacuum cleaning component in conjunction with the auxiliary operating lever. The specific operation is as follows:

[0053] Connect the auxiliary cylinder 8 to the corresponding end of the main hollow rod 21 by thread. Then, place the open port of the connecting cylinder 3 against the gap between the drawer switch operating handle and the drawer switch or the surface of the operating handle, and turn on the suction pump 10. The suction pump 10 will actively perform negative suction cleaning through the flow channel space formed by the auxiliary cylinder 8, the auxiliary conduit 22, the hollow connecting rod 1, and the connecting cylinder 3. Then, the air containing dust will enter the interior of the support cylinder 91 through the output end of the suction pump 10 and the air guide ring groove 12. Finally, it will be filtered by the filter screen 92, the air will be discharged, and the dust will be temporarily left inside the support cylinder 91. In the subsequent continuous operation of the suction pump 10, the cleaning effect of negative suction, filtration and collection will continue to be generated.

[0054] After the filter element 9 has been used for a certain period of time, the scraper 94 can be rotated synchronously by turning the T-shaped rod 93. Then, the scraper 94 can be used to clean the filter surface of the filter screen 92 to prevent clogging. Alternatively, the support cylinder 91 can be turned to separate the filter element 9 from the auxiliary cylinder 8, and the dust collected inside the filter element 9 can be poured out and cleaned directly.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention. The invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
