Description

Technical Field

[0001] This utility model belongs to the field of instrumentation technology, specifically relating to a connection wire locking structure and an instrument. Background Technology

[0002] Instruments and meters are devices used to measure, detect, control, and record physical and chemical quantities. They are widely used in industrial production, scientific research, medical treatment, environmental monitoring, and other fields. By sensing external signals and converting them into readable numerical values ​​or control commands, they help improve work efficiency, ensure product quality, and guarantee safety. Currently, instruments and meters are becoming increasingly intelligent and automated, enabling them to more accurately meet the needs of various industries.

[0003] Locking structures are stabilizing devices used in mechanical, electronic, or control systems to fix components or maintain their functional state. Their main function is to ensure that critical components in the system are not disturbed or changed by external factors during operation through specific construction or mechanisms. Common locking structures include mechanical locks, electronic locks, and software locks, and are widely used in fields such as security protection, data protection, and equipment protection.

[0004] In the daily use of instruments and meters, it is usually necessary to connect the detection head or other external devices to the main body of the instrument via a connecting cable to achieve data acquisition and display functions. Traditional instrument connecting cables mainly use a plug-in interference fit fixing method. While this structure is simple and easy to use, it has significant drawbacks in practical applications: when the operator accidentally pulls the connecting cable or the equipment is subjected to vibration, the connection can easily become loose, leading to data transmission interruption and affecting the normal operation of the testing work. This instability is particularly pronounced in complex working environments such as industrial sites, and in severe cases, it can even lead to data loss or misinterpretation. Utility Model Content

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A connecting wire locking structure is provided for locking a connecting wire to the socket of an instrument. The connecting wire has a plug, and a cylindrical locking block coaxial with the connecting wire is provided near the plug. The locking structure includes a fixed ring and a rotating ring, with the rotating ring rotatably connected to the outside of the fixed ring. One end of the fixed ring is used to connect to the instrument, and the other end face has an annular groove. The annular groove has an inner groove wall and an outer groove wall. The inner groove wall has a plurality of first through holes evenly distributed circumferentially, and the outer groove wall has a plurality of second through holes corresponding one-to-one with the first through holes. A connecting rod is slidably installed in the first through hole. The end of the connecting rod near the center of the fixed ring extends out of the first through hole and is connected to an arc-shaped locking block. The end of the connecting rod away from the center of the fixed ring extends into the annular groove and is connected to a baffle. The size of the baffle is larger than the size of the first through hole. A rope is connected to the baffle. One end of the rope extends out of the second through hole and is connected to the inner wall of the rotating ring. A first spring is sleeved on the rope in the annular groove. When the first spring is at its maximum length, the plurality of arc-shaped locking blocks form a circular locking ring, and the diameter of the circular locking ring is smaller than the diameter of the cylindrical locking block.

[0008] Furthermore, there are four first through holes and four second through holes, and four ropes, four first springs, four connecting rods, and four arc-shaped locking blocks.

[0009] Furthermore, the first through hole is a square hole, and the connecting rod is a square rod that matches the first through hole.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments thereof. It should be noted that the following detailed description of the present invention is for illustrative purposes only and is not intended to limit the scope of the invention.

[0026] like Figure 1As shown, this embodiment provides a connecting wire locking structure for locking the connecting wire 2 onto the socket of the instrument 1. The connecting wire 2 has a plug, and a cylindrical locking block coaxial with the connecting wire 2 is provided near the plug of the connecting wire 2. The instrument 1 is used to display the detection data and control the operation of the device, and the connecting wire 2 is used to transmit the detection data to the instrument 1.

[0027] like Figure 2 , 3 As shown, the locking structure includes a fixed ring 3 and a rotating ring 4, with the rotating ring 4 rotatably connected to the outside of the fixed ring 3. In this embodiment, the inner wall of the rotating ring 4 is provided with a groove, and the outer wall of the fixed ring 3 is provided with a slider that matches the groove. Through the cooperation of the slider and the groove, the rotating ring 4 is rotatably connected relative to the fixed ring 3. A gap is provided between the rotating ring 4 and the fixed ring 3 to facilitate the rotation of the rotating ring 4. At the same time, multiple protrusions are uniformly provided circumferentially on the outer surface of the rotating ring 4 to increase friction, facilitating the rotation of the rotating ring 4.

[0028] like Figure 2 , 3 As shown, one end of the fixing ring 3 is used to connect to the instrument 1, and the other end face has an annular groove. The annular groove has an inner groove wall and an outer groove wall. The inner groove wall has a plurality of first through holes evenly distributed along the circumference, and the outer groove wall has a plurality of second through holes corresponding one-to-one with the first through holes. The first through holes and the second through holes are located on the same radial line of the fixing ring 3. In this embodiment, there are four first through holes and four second through holes. Among them, the first through holes are square holes.

[0029] like Figure 2 , 3 As shown, a connecting rod 8 is slidably installed inside the first through hole. The connecting rod 8 is a square rod that matches the first through hole. Under the limiting effect of the first through hole, the connecting rod 8 can only move along the direction of the first through hole and will not shake or rotate. One end of the connecting rod 8 near the center of the fixing ring 3 extends out of the first through hole and is connected to an arc-shaped locking block 9. The other end of the connecting rod 8 away from the center of the fixing ring 3 extends into the annular groove and is connected to a baffle 7. The size of the baffle 7 is larger than the size of the first through hole. The baffle 7 is used to limit the connecting rod 8 from exceeding its range of movement and causing it to fall off. A rope 5 is connected to the baffle 7. One end of the rope 5 extends out from the second through hole and is connected to the inner wall of the rotating ring 4. The rope 5 is used to pull the baffle 7 to move. The rotating ring 4 facilitates pulling multiple ropes 5 together. A first spring 6 is sleeved on the rope 5 in the annular groove. The first spring 6 is used to automatically reset the baffle 7 and the connecting rod 8. A cover plate 18 is also fastened to the annular groove to prevent the components in the annular groove from shifting or even slipping, which would affect the use of the locking assembly. In this embodiment, there are four ropes 5, four first springs 6, four connecting rods 8, and four arc-shaped locking blocks 9.

[0030] When the first spring 6 is at its maximum length, the four arc-shaped locking blocks 9 form a circular locking ring, and the diameter of the circular locking ring is smaller than the diameter of the cylindrical locking block baffle 7. The return of the first spring 6 causes the circular locking ring to lock the connecting wire 2 in place.

[0031] When the locking structure is in operation, rotating the rotating ring 4 causes it to rotate relative to the fixed ring 3. The rotating ring 4 pulls multiple ropes 5 to move along the second through hole. The ropes 5 pull the baffle 7 and the connecting rod 8, causing the first spring 6 to be compressed. The connecting rod 8 pulls the four arc-shaped locking blocks 9 to move closer to the rotating ring 4, causing the locking assembly to expand. Then, the plug of the connecting wire 2 is inserted into the socket of the instrument 1, and the rotating ring 4 is released. Under the rebound of the first spring 6, the four connecting rods 8 move closer to the center of the locking assembly, causing the four arc-shaped locking blocks 9 to move closer to each other, thereby locking the connecting wire 2. Unlocking the connecting wire 2 is done in the same way.

[0032] This embodiment also provides an instrument, such as Figure 1 As shown, the instrument 1 is equipped with the aforementioned locking structure and fixing components, which are used to fix the instrument 1 to the support platform. There are two sets of fixing components, which are respectively installed on both sides of the instrument 1.

[0033] like Figure 4 As shown, the fixing assembly includes a housing 11, a pressure rod 16, a suction cup 13, and a piston 15 and a second spring 14 arranged sequentially from top to bottom inside the housing 11. The side of the housing 11 is fixedly connected to the instrument 1 via a fixing block 10. The top and bottom of the housing 11 are respectively provided with a third through hole and a fourth through hole. The suction cup 13 is located at the bottom of the housing 11 and communicates with the interior of the housing 11 through the fourth through hole. The piston 15 is slidably sealed to the inner wall of the housing 11. The upper side of the piston 15 is connected to one end of the pressure rod 16, and the other end of the pressure rod 16 extends out of the housing 11 through the third through hole. The lower side of the piston 15 is connected to one end of the second spring 14, and the other end of the second spring 14 is connected to the bottom of the housing 11. A pressure plate 17 is provided at the other end of the pressure rod 16 extending out of the housing 11.

[0034] The outer casing 11 is used to connect and protect the internal parts, and to restrict the movement direction of the pressure rod 16, piston 15 and second spring 14, and keep them stable. The fixing block 10 is used to connect the outer casing 11 with the instrument 1. The suction cup 13 is used to fix the instrument 1 on the plane. The second spring 14 is used to push the pressure rod 16 to move upward. The pressure rod 16 is used to withstand the thrust of the second spring 14 and drive the pressure rod 16 to return to its original position. The pressure rod 16 is used to push the piston 15 to compress the second spring 14. The pressure plate 17 is used to facilitate manual pressing of the pressure rod 16 to move.

[0035] The working principle of the locking structure and fixing components on the above-mentioned instruments is as follows:

[0036] When using instrument 1 to detect a substance, first fix instrument 1 on the table. Press the lever 16 to move the piston 15 downwards, compressing the second spring 14 and expelling the air from the outer casing 11. Then release the lever 16, and the second spring 14 will push the piston 15 upwards, creating a negative pressure inside the outer casing 11. The suction cup 13 will firmly adhere to the table, keeping instrument 1 stable and preventing it from falling off. Next, install the connecting wire 2 on instrument 1. By rotating the rotating ring 4, the rope 5 pulls the baffle 7, compressing the first spring 6 and causing the connecting rod 8 to retract into the fixing ring 3. This causes the arc-shaped locking block 9 to move towards the fixing ring 3. Then, insert the connecting wire 2 into the socket on instrument 1. At this point, release the rotating ring 4. Under the limit of the fixing ring 3, the first spring 6 pushes the baffle 7, pushing the connecting rod 8 out. The arc-shaped locking block 9 then wraps around the connecting wire 2, locking it in place and preventing it from falling off due to pulling. This method is time-saving, labor-saving, and simple to operate.

[0037] This embodiment provides a connecting wire locking structure. The locking component can fix the connecting wire 2 to the instrument 1. The rotating ring 4 can synchronously drive the rope 5 to move, so that the arc-shaped locking block 9 can open to allow the connecting wire 2 to pass through the center of the locking component. Through the rebound of the first spring 6, the arc-shaped locking blocks 9 can move closer to each other, locking and securing the connecting wire 2. The provided instrument 1 is fixed on a plane by the designed fixing component. By pressing the pressure rod 16, the piston 15 compresses the second spring 14. Then, the rebound of the second spring 14 pushes the piston 15 to reset, so that the suction cup 13 generates negative pressure, thereby adsorbing the instrument 1 onto the operating table and avoiding accidental touch that could cause displacement or even fall, resulting in damage to the instrument 1.

[0038] Finally, it should be noted that the features mentioned and / or shown in the above description of exemplary embodiments of the present invention can be combined in the same or similar manner with one or more other embodiments, combined with features in other embodiments, or substituted for corresponding features in other embodiments. These combined or substituted technical solutions should also be considered as included within the protection scope of the present invention.
