Description

Technical Field

[0001] This utility model relates to the field of metrology and testing technology, and in particular to a portable metrology and testing device. Background Technology

[0002] The gas metering and detection instrument is a high-performance and versatile professional device. Equipped with a high-precision gas sensor, it can quickly and accurately detect the composition and concentration of various gases, while also accurately measuring parameters such as gas flow rate and volume. It features an intelligent operating interface that is simple, intuitive, and easy to use. Parameters can be flexibly set according to different detection needs. The instrument adopts a portable design, is small and lightweight, and is easy to carry to various complex detection sites.

[0003] Existing technologies include, for example, the utility model with publication number CN215910442U. This utility model relates to the field of gas detection, specifically a gas metering and detection device, including a detector body. Protective corner blocks are fixedly installed at the four corners of the front of the detector body. Vent holes are provided at the front and rear ends of the protective corner blocks. A middle support plate is fixedly installed in the middle of the protective corner blocks. An outer support plate is fixedly installed on the top of the middle support plate, and an inner support plate is fixedly installed at the bottom of the middle support plate. This utility model uses the protective corner blocks, vent holes, outer support plate, and inner support plate to generate a buffering effect through deformation when the device is accidentally dropped. The wave-shaped outer and inner support plates can transmit and disperse the force received, effectively reducing the damage caused by the drop. The vent holes can form a gas resistance to provide secondary protection when the pressure generated by the drop is large. The outer wave-shaped side protection blocks are ergonomic, making the grip more comfortable and less prone to slipping.

[0004] However, during testing, the data cable usually needs to be inserted into the interface. After the plug and interface are squeezed together for a long time, the connection becomes unstable, making it difficult for the gas meter to accurately measure parameters such as gas flow and volume, thus giving incorrect test data and affecting the accurate assessment of gas usage. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that, during testing, the data cable usually needs to be inserted into the interface, and the connection becomes unstable after the plug and interface are squeezed for a long time. This causes the gas metering detector to be unable to accurately measure parameters such as gas flow and volume, thus giving incorrect test data and affecting the accurate assessment of gas usage. Therefore, a portable metering and testing device is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a portable measuring and testing device, comprising a detector and a connecting device. A display screen is mounted on the surface of the detector. An interface is fixedly connected to the upper surface of the detector. A data plug is inserted into the upper surface of the interface. The connecting device is disposed on the surface of the interface and includes a stop bracket fixed to the surface of the interface. A rubber sleeve is fitted over the surface of the interface. A pressure spring is fixedly connected to the lower surface of the rubber sleeve. The side of the pressure spring away from the rubber sleeve is fixedly connected to the interface. A guide rail is fixedly connected to the surface of the data plug. A circular sleeve is rotatably connected to the inner wall of the guide rail. A push rod is fixedly connected to the surface of the circular sleeve. By setting up the connecting device, when the data plug is inserted, the rubber sleeve moves downward under force, dispersing the impact force when the plug is inserted and reducing the direct, hard compression between the plug and the interface. When the plug needs to be removed, the circular sleeve is rotated to align the clip with the through hole, and the rubber sleeve returns to its original position under the action of the pressure spring. This further reduces friction and compression damage between the plug and the interface during the removal process, extends the service life of the data plug and the interface, and reduces the probability of equipment failure due to damage to connecting components.

[0007] Preferably, there are two push rods, which are symmetrically arranged. The push rods are important components connecting the sleeve and the card. When the sleeve rotates under the push of the fixed plate, the push rod can transmit the force generated by the rotation of the sleeve to the card, so that the card can move according to the design requirements.

[0008] Preferably, a card is fixedly connected to the lower surface of the push rod, and a through hole is opened on the surface of the stop. The push rod is equipped with a card. When the data plug is inserted into the interface, the card passes through the through hole. Under the action of the subsequent mechanism, the card will move away from the through hole and abut against the stop, thus forming a mechanical locking structure.

[0009] Preferably, the card engages with the through hole, and a guide rod is fixedly connected to one side of the guide rail.

[0010] Preferably, a fixing plate is fixedly connected to the surface of the circular sleeve. The surface of the fixing plate has a circular hole. By setting the fixing plate, the fixing spring generates elastic force after it is unrestrained. This elastic force first acts on the fixing plate. The fixing plate, as a force-bearing carrier, bears the elastic force released by the fixing spring and provides a power source for subsequent actions.

[0011] Preferably, the guide rod is slidably connected to the round hole on the surface of the fixing plate, and the rubber sleeve contacts the data plug. By setting the rubber sleeve, when the data plug is inserted into the interface, the rubber sleeve first abuts against the data plug, which can buffer the impact force when the plug is inserted, avoid direct rigid contact between the plug and the interface, thereby reducing the damage that may be caused to the interface and the plug, and extending the service life of both.

[0012] Preferably, a fixing spring is sleeved on the surface of the guide rod. The two ends of the fixing spring are fixedly connected to the guide rail and the fixing plate, respectively. By setting the fixing spring, the fixing spring stores elastic potential energy when it is restrained. When the rubber sleeve is subjected to force and moves downward to loosen the round sleeve, the fixing spring loses its restraint and releases elastic potential energy to generate elastic force. This elastic force is the key driving force for the entire structure to fix the data plug. It pushes the fixing plate to drive the subsequent rotation of the round sleeve, the movement of the push rod and the card, and a series of other actions, ultimately causing the card to move away from the through hole and abut against the stop, thereby firmly fixing the data plug in the interface.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, before use, the data plug is inserted into the interface. At this time, the data plug abuts against the rubber sleeve, and the card passes through the through hole. The rubber sleeve moves downward under force, and at the same time, the round sleeve is released. The fixing spring loses its restraint and generates elastic force to squeeze the fixing plate. The fixing plate is pushed by force to rotate the round sleeve. As the round sleeve rotates, it drives the push rod and the card to move. The card then moves away from the through hole and abuts against the stop. At this time, the card fixes the data plug. Rotating the round sleeve causes the card to correspond with the through hole, and the data plug can be pulled out. The rubber sleeve loses its restraint and, together with the pressure spring, reduces the squeezing damage between the data plug and the interface. By designing this utility model, when the data plug is inserted, the rubber sleeve moves downward under force, dispersing the impact force when the plug is inserted and reducing the direct and rigid squeezing between the plug and the interface. When it is necessary to remove the plug, the circular sleeve is rotated to align the card with the through hole, and the rubber sleeve is reset under the action of the pressure spring. This further reduces friction and squeezing damage between the plug and the interface during the plug removal process, extends the service life of the data plug and the interface, and reduces the probability of equipment failure due to damage to the connecting parts.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a portable measuring and testing device, including a detector 1 and a connecting device 5. A display screen 2 is installed on the surface of the detector 1, an interface 3 is fixedly connected to the upper surface of the detector 1, a data plug 4 is inserted into the upper surface of the interface 3, and the connecting device 5 is disposed on the surface of the interface 3.

[0017] In this embodiment: the connecting device 5 includes a baffle 51, which is fixed to the surface of the interface 3. A rubber sleeve 511 is fitted onto the surface of the interface 3. A pressure spring 52 is fixedly connected to the lower surface of the rubber sleeve 511. The side of the pressure spring 52 away from the rubber sleeve 511 is fixedly connected to the interface 3. A guide rail 54 is fixedly connected to the surface of the data plug 4. A circular sleeve 53 is rotatably connected to the inner wall of the guide rail 54. A push rod 55 is fixedly connected to the surface of the circular sleeve 53. By setting the connecting device 5, when the data plug 4 is inserted, the rubber sleeve 511 moves downward under force, dispersing the impact force when the plug is inserted and reducing the direct and rigid squeezing between the plug and the interface 3. When the plug needs to be pulled out, the circular sleeve 53 is rotated so that the card 56 aligns with the through hole 57. The rubber sleeve 511 is reset under the action of the pressure spring 52, further reducing the friction and squeezing damage between the plug and the interface 3 during the plug pulling process, extending the service life of the data plug 4 and the interface 3, and reducing the probability of equipment failure due to damage to the connecting parts.

[0018] Specifically, there are two push rods 55, which are symmetrically arranged. The push rods 55 are important components connecting the sleeve 53 and the card 56. When the sleeve 53 rotates under the push of the fixed plate 59, the push rods 55 can transmit the force generated by the rotation of the sleeve 53 to the card 56, so that the card 56 can move according to the design requirements.

[0019] Specifically, a card 56 is fixedly connected to the lower surface of the push rod 55, and a through hole 57 is opened on the surface of the stop 51. The push rod 55 is equipped with the card 56. When the data plug 4 is inserted into the interface 3, the card 56 passes through the through hole 57. Under the action of the subsequent mechanism, the card 56 will move away from the through hole 57 and abut against the stop 51, thus forming a mechanical locking structure.

[0020] Specifically, the card 56 engages with the through hole 57, and a guide rod 58 is fixedly connected to one side of the guide rail 54.

[0021] Specifically, a fixing plate 59 is fixedly connected to the surface of the circular sleeve 53. The surface of the fixing plate 59 has a circular hole. By setting the fixing plate 59, the fixing spring 510 generates elastic force after it is unrestrained. This elastic force first acts on the fixing plate 59. The fixing plate 59, as a force-bearing carrier, bears the elastic force released by the fixing spring 510 and provides a power source for subsequent actions.

[0022] Specifically, the guide rod 58 is slidably connected to the round hole on the surface of the fixing plate 59, and the rubber sleeve 511 is in contact with the data plug 4.

[0023] In this embodiment: by setting a rubber sleeve 511, when the data plug 4 is inserted into the interface 3, the rubber sleeve 511 first abuts against the data plug 4, which can buffer the impact force when the plug is inserted, avoid direct rigid contact between the plug and the interface 3, thereby reducing the damage that may be caused to the interface 3 and the plug, and extending the service life of both.

[0024] Specifically, a fixing spring 510 is sleeved on the surface of the guide rod 58, and the two ends of the fixing spring 510 are fixedly connected to the guide rail 54 and the fixing plate 59 respectively.

[0025] In this embodiment: By setting a fixing spring 510, the fixing spring 510 stores elastic potential energy when it is restrained. When the rubber sleeve 511 is subjected to force and moves downward to loosen the round sleeve 53, the fixing spring 510 loses its restraint and releases elastic potential energy to generate elastic force. This elastic force is the key driving force for the entire structure to fix the data plug 4. It pushes the subsequent round sleeve 53 to rotate, the push rod 55 and the card 56 to move, and a series of other actions through the squeezing of the fixing plate 59. Finally, the card 56 moves away from the through hole 57 and abuts against the stop 51, thereby firmly fixing the data plug 4 in the interface 3.

[0026] Working principle: Before use, insert the data plug 4 into the interface 3. At this time, the data plug 4 abuts against the rubber sleeve 511, and the card 56 passes through the through hole 57. The rubber sleeve 511 moves downward under force, and at the same time, the round sleeve 53 is released. The fixing spring 510 loses its restraint and generates elastic force to squeeze the fixing plate 59. The fixing plate 59 is pushed by the force to rotate the round sleeve 53. As the round sleeve 53 rotates, it drives the push rod 55 and the card 56 to move. The card 56 then moves away from the through hole 57 and abuts against the stop 51. At this time, the card 56 fixes the data plug 4. Rotating the round sleeve 53 causes the card 56 to align with the through hole 57, and the data plug 4 can be pulled out. The rubber sleeve 511 moves downward under force, and the card 56 moves downward under force. The card 56 then moves downward under force, and the card 56 moves downward under force. The card 56 ... 11. By removing the constraint of the pressure spring 52, the squeezing damage between the data plug 4 and the interface 3 is reduced. By setting up this utility model, when the data plug 4 is inserted, the rubber sleeve 511 moves downward under force, dispersing the impact force when the plug is inserted and reducing the hard direct squeezing between the plug and the interface 3. When it is necessary to pull out the plug, the circular sleeve 53 is rotated so that the card 56 aligns with the through hole 57, and the rubber sleeve 511 is reset under the action of the pressure spring 52. This further reduces the friction and squeezing damage between the plug and the interface 3 during the plug pulling process, extends the service life of the data plug 4 and the interface 3, and reduces the probability of equipment failure caused by damage to the connecting parts.
