Description

Technical Field

[0001] This utility model belongs to the field of adjustment knob technology, and in particular relates to a power station equipment parameter configuration adjustment knob. Background Technology

[0002] A power station equipment parameter adjustment knob is a physical control component used to manually adjust key electrical parameters (such as output voltage, output current, protection threshold, frequency, or phase) within a power station (such as a substation, distribution room, or specific power equipment). It is typically circular, rotatable, and directly mounted on the equipment panel or controller, allowing operators or technicians to conveniently and in real-time fine-tune or set the equipment's operating status on-site according to operational needs or testing requirements, ensuring the stability and safety of the power supply or meeting specific load conditions.

[0003] However, the adjustment knob lacks a limit mechanism, and the knob is easily accidentally touched after adjustment, causing it to turn again, which in turn affects the normal operation of the power station equipment.

[0004] To address the aforementioned issues, this application proposes a power station equipment parameter configuration adjustment knob. Utility Model Content

[0005] The purpose of this utility model is to provide a power station equipment parameter configuration adjustment knob, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a power station equipment parameter configuration adjustment knob, comprising a base and a torsion cover rotatably connected to the front end of the base. An adjustment ring is fixedly connected to the base, and a rotatable adjustment disc is connected between the adjustment ring and the base. A release button that can move axially is connected to the end of the torsion cover away from the base. A return spring is provided between the release button and the torsion cover. A rectangular rod is formed inside the release button and is movably connected to the adjustment disc. A base plate is fixedly installed at the bottom of the rectangular rod. When the release button is pressed inward, the adjustment ring and the adjustment disc disengage from their circumferential limit, and the torsion cover can rotate on the base. Conversely, when the release button is not under force, the adjustment ring and the adjustment disc are circumferentially locked, and the torsion cover cannot rotate on the base.

[0008] Furthermore, the inner side of the adjusting ring is provided with several positioning grooves along the circumference, the end of the adjusting ring away from the base is formed with a retaining ring with an inner diameter smaller than the adjusting disc, and the outer side of the adjusting ring is fixed with a mounting ear that is installed on the base by screws.

[0009] Furthermore, the adjusting plate has a connecting hole, and a movable hole is provided radially between the connecting hole and the outer side of the adjusting plate. A movable locking pin is provided inside the movable hole, and a stop pin is formed at one end of the locking pin near the connecting hole. A locking spring is sleeved on the outside of the stop pin.

[0010] Furthermore, a clearance groove with a diameter larger than the abutment and smaller than the locking spring is provided on one side of the rectangular rod.

[0011] Furthermore, the inside of the twist cover is formed with a movable groove whose inner diameter matches the outer diameter of the release button, and a partition is also formed inside the twist cover, with a through hole for a rectangular rod to pass through.

[0012] Furthermore, the base has clearance holes for the rectangular rod to pass through and rotate, and the rear end of the base is also formed with a mounting sleeve.

[0013] Furthermore, a bearing is provided between the base and the twist cover.

[0014] Furthermore, the release button has a spring groove formed on its inner side for a reset spring.

[0015] This utility model has the following beneficial effects:

[0016] This utility model controls whether the twist cover can rotate on the base by the cooperation between the adjusting ring and the adjusting plate. The adjusting ring and the adjusting plate have the characteristics of simple structure, easy assembly and maintenance, and at the same time can ensure the reliability of preventing accidental contact.

[0017] This invention uses a release button at the front end of the twist cover to control the disengagement between the adjusting ring and the adjusting disc. The driving direction of the release button is different from that of the twist cover, so the twist cover will not rotate no matter which part is accidentally touched. At the same time, the operator can easily adjust the twist cover with one hand, ensuring both reliability and ease of use while preventing accidental touches.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figures 1-6As shown, this utility model is a power station equipment parameter configuration adjustment knob, including a base 1 and a twist cover 2 rotatably connected to the front end of the base 1. An adjustment ring 4 is fixedly connected to the base 1, and a rotatable adjustment disk 5 is connected between the adjustment ring 4 and the base 1. A release button 3 that can move axially is connected to the end of the twist cover 2 away from the base 1. A return spring 33 is provided between the release button 3 and the twist cover 2. A rectangular rod 31 is formed on the inner side of the release button 3 and is movably connected to the adjustment disk 5. A base plate 6 is fixedly installed at the bottom of the rectangular rod 31. In this embodiment, there is an installation space for electronic control adjustment components between the base 1 and the twist cover 2, and a through hole for leading out the control line is provided on the inner side of the base 1.

[0031] Specifically, when the release button 3 is pressed inward, the adjusting ring 4 and the adjusting disk 5 are disengaged from the circumferential limit, and the twist cover 2 can rotate on the base 1. Conversely, when the release button 3 is not under force, the adjusting ring 4 and the adjusting disk 5 are circumferentially locked, and the twist cover 2 cannot rotate on the base 1, thus achieving the purpose of preventing accidental touch.

[0032] Specifically, the inner side of the adjusting ring 4 is provided with several positioning grooves 41 along the circumference. The end of the adjusting ring 4 away from the base 1 is formed with a retaining ring 42 with an inner diameter smaller than that of the adjusting plate 5. The outer side of the adjusting ring 4 is fixed with an installation ear 43 that is installed to the base 1 by screws. In this embodiment, the adjusting ring 4 also plays a limiting role in the installation of the adjusting plate 5 when it is locked and disengaged from the adjusting plate 5.

[0033] Furthermore, the adjusting plate 5 has a connecting hole 51, and a movable hole 52 is provided radially between the connecting hole 51 and the outer side of the adjusting plate 5. A movable locking pin 53 is provided inside the movable hole 52. A stop pin 531 is formed at one end of the locking pin 53 near the connecting hole 51. A locking spring 54 is sleeved on the outside of the stop pin 531. In this embodiment, the diameter of the stop pin 531 is smaller than that of the locking pin 53, and an installation space for the locking spring 54 is formed on its outer side, so that the locking pin 53, the stop pin 531, and the locking spring 54 can be easily installed into the movable hole 52.

[0034] Furthermore, a relief groove 311 with a diameter larger than the abutment 531 and smaller than the locking spring 54 is provided on one side of the rectangular rod 31. When the locking pin 53 moves toward the connecting hole 51, the abutment 531 can abut against the outside of the relief groove 311 to prevent the locking spring 54 from getting stuck due to the movement of the rectangular rod 31.

[0035] Specifically, the inside of the twist cover 2 is formed with a movable groove 21 whose inner diameter matches the outer diameter of the release button 3. The movable groove 21 ensures the radial reliability of the release button 3. The inside of the twist cover 2 is also formed with a partition 22. The partition 22 has a through hole 221 for the rectangular rod 31 to pass through. Through the rectangular structure, when the twist cover 2 is rotated, the release button 3 can rotate synchronously, thereby achieving the purpose of adjusting the twist cover 2 on the base 1.

[0036] Specifically, the base 1 has a clearance hole 11 for the rectangular rod 31 to pass through and rotate. The rear end of the base 1 is also formed with a mounting sleeve 12. In this embodiment, the base 1 can be connected to the power station equipment through the mounting sleeve 12. The inner side of the mounting sleeve 12 can be threaded. During actual installation, the knob is located outside the equipment. The equipment has a reserved mounting hole that matches the mounting sleeve 12. The mounting sleeve 12 passes through the mounting hole from the outside to the inside and is fixed by screws. At the same time, the equipment also has a reserved wiring hole for the knob to be connected to electricity.

[0037] Specifically, a bearing 7 is provided between the base 1 and the twist cover 2. The base 1 has an installation position for the bearing 7 on its outer side, and the inner movable end of the bearing 7 is fixed to the base 1 by adhesive bonding. The outer movable end of the bearing 7 is fixed to the inner side of the twist cover 2 by adhesive bonding, thereby ensuring the smooth rotation of the twist cover 2 on the base 1.

[0038] Specifically, the release button 3 has a spring groove 32 formed on its inner side for the reset spring 33. The spring groove 32 limits the reset spring 33 and prevents the reset spring 33 from shifting between the release button 3 and the twist cover 2, thus ensuring structural reliability.

[0039] Understandably, this utility model controls the rotation of the twist cover on the base through the cooperation of the adjusting ring and the adjusting disc, resulting in a simple structure that is easy to assemble and maintain. The release button is located at the front end of the twist cover, and its driving direction is different from the rotation direction, ensuring that accidental activation of either the twist cover or the button will not cause rotation, thus ensuring reliable protection against accidental activation. At the same time, operators can easily unlock and adjust the cover by pressing the button with one hand, taking into account ease of use.

[0040] One specific application of this embodiment is:

[0041] Assembly: Apply adhesive to the inner side of bearing 7 and connect it to base 1. Apply adhesive to the outer side of bearing 7 and connect the torsion cover 2 to the front end of base 1. At this time, the outer side of bearing 7 is fixed to torsion cover 2 by adhesive bonding. Locking pin 53 is placed in movable hole 52, locking spring 54 is placed outside of abutment 531, adjusting plate 5 is installed in adjusting ring 4, and adjusting ring 4 is fixedly installed to base 1 by mounting ear 43. At this time, a rotation gap for adjusting plate 5 is formed between adjusting ring 4 and base 1. Return spring 33 is placed in spring groove 32, rectangular rod 31 passes through through hole 221, clearance hole 11, and connecting hole 51, and return spring 33 abuts between spring groove 32 and partition plate 22. Base plate 6 is connected to the bottom of rectangular rod 31 and fixed by bolts. The assembly is completed, which is the attachment. Figure 1-2 The state shown;

[0042] Adjustment: After bending your index finger, press the back of your finger against the release button 3 and push it towards the twist cover 2. At this time, the release button 3 moves in the movable groove 21, the return spring 33 is compressed, and the rectangular rod 31 and the adjustment plate 5 move inward. At this time, the clearance groove 311 corresponds to the locking pin 53. Pinch the outer arc of the twist cover 2 with your thumb and middle finger and rotate it. During the rotation, the locking pin 53 comes out of the positioning groove 41. During this process, the locking spring 54 is compressed, and the side of the locking pin 53 near the abutment 531 enters the clearance groove 311. Until the adjustment is completed, the locking pin 53 automatically engages with the corresponding positioning groove 41 under the action of the locking spring 54. Release the twist cover 2 and the release button 3. Under the action of the return spring 33, the rectangular rod 31 moves outward, and the clearance groove 311 is misaligned with the locking pin 53. At this time, even if you rotate the twist cover 2, it will not be able to be turned because the locking pin 53 has no room to move back.
