Description

Technical Field

[0001] This utility model relates to the field of power detection technology, and in particular to a power detection and protection device. Background Technology

[0002] Electrical equipment is mainly used to maintain the normal operation and transmission of electricity. During use, electrical equipment needs to be inspected regularly to ensure its normal operation and avoid major losses caused by sudden shutdown of electrical equipment. Among them, using a test pen to check whether the electrical equipment is properly powered is the most common inspection work. At present, in order to reduce the damage to the detection end of the test pen, a protective cover is usually installed on the test pen to protect the detection end of the test pen.

[0003] A related technology includes a Chinese patent with authorization announcement number CN214374923U, which provides a protective device for a handheld electrical testing equipment. The device includes a testing equipment body and a protective cover. A connecting plate is mounted on the protective cover. The testing equipment body has a mounting groove for inserting the connecting plate. A positioning block is slidably disposed within the mounting groove. The positioning block has an arc-shaped structure on the side facing the connecting plate. A positioning groove is formed on the connecting plate for inserting the positioning block. A sliding cavity is formed on the testing equipment body, communicating with the mounting groove. A sliding plate is slidably disposed within the sliding cavity. A pull rod is mounted on one end of the sliding plate, with the end of the pull rod away from the sliding plate located outside the testing equipment body. A connecting rod is mounted on the other end of the sliding plate, with the end of the connecting rod away from the sliding plate connected to the positioning block. A return spring is sleeved on the connecting rod, with one end welded to the sliding plate and the other end welded to the inner wall of the sliding cavity. When the positioning block is inserted into the positioning groove, the protective cover is connected to the main body of the testing equipment. The protective cover and the testing end of the testing equipment body are shielded and protected. When the testing end of the testing equipment body is exposed, the pull rod is pulled to separate the positioning block from the positioning groove, and then the protective cover is separated from the main body of the testing equipment.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: because the pull rod is located on a small part outside the detection device body, it is inconvenient for the user to grasp the pull rod and pull it, which makes it inconvenient for the user to disassemble the protective cover. Utility Model Content

[0005] To facilitate the removal of the protective cover by the operator, this application provides an electrical detection and protection device.

[0006] The power detection and protection device provided in this application adopts the following technical solution: A power detection and protection device includes a protective cover, an installation ring inserted inside the protective cover for fixed connection with the main body of the detection equipment, a plug-in ring fixedly disposed on the inner wall of the installation ring, a set of through holes through the protective cover, a sliding rod inserted into the through holes and slidably connected to the through holes, a reset component disposed between the sliding rod and the protective cover, the reset component for positioning the sliding rod at one end inside the protective cover close to the inner wall of the protective cover, a snap-fit ​​component disposed on the sliding rod at the end inside the protective cover, the snap-fit ​​component for forming a snap-fit ​​gap for the plug-in ring to be inserted.

[0007] By adopting the above technical solution, the mounting ring is fixedly connected to the main body of the testing equipment. When the user presses the sliding rod, the sliding rod moves the locking assembly, causing the locking gap to move closer to the central axis of the protective cover. When the user releases the sliding rod, the sliding rod, under the action of the reset assembly, moves the locking assembly, causing the locking gap to move away from the central axis of the protective cover. When the protective cover is used to shield the testing end of the testing equipment, the testing end of the testing equipment is inserted into the protective cover, and the locking gap is brought closer to the central axis of the protective cover until the insertion ring is aligned with the locking gap. At this point, the reset assembly moves the locking gap away from the central axis of the protective cover, allowing the insertion ring to be inserted into the locking gap. At this time, the protective cover is fitted onto the mounting ring and... The insertion ring is inserted into the snap-fit ​​gap to connect the protective cover to the main body of the testing equipment and to shield the testing end of the main body of the testing equipment. When the protective cover is separated from the main body of the testing equipment, the user keeps pressing the slide bar with one hand. The slide bar moves the snap-fit ​​assembly, separating the insertion ring from the snap-fit ​​gap. This keeps the insertion ring and the snap-fit ​​gap separated and also clamps and fixes the protective cover. The user fixes the main body of the testing equipment with the other hand. Then, the protective cover and the main body of the testing equipment are moved away from each other to remove the protective cover. Although the slide bar outside the protective cover is small, the user only needs to press the slide bar to easily remove the protective cover.

[0008] Preferably, the through holes are arranged opposite to each other.

[0009] By adopting the above technical solution, it is easy for users to continuously press the two oppositely arranged sliders with one hand.

[0010] Preferably, an end plate is fixedly installed at one end of the slide rod outside the protective cover, and the end plate is connected to the reset assembly.

[0011] By adopting the above technical solution, the end plate increases the contact area between the slide bar and the hand, making it easier for the user to continuously press the slide bar with one hand.

[0012] Preferably, a rubber layer is provided on the outer wall of the end plate, and the rubber layer is connected to the reset assembly.

[0013] By adopting the above technical solution, the rubber layer increases the friction of the end plate, making it easier for the user to continuously press the slide bar with one hand.

[0014] Preferably, the reset assembly includes a reset spring, which is sleeved on the slide rod. One end of the reset spring is fixedly connected to the rubber layer, and the other end of the reset spring is fixedly connected to the outer wall of the protective cover.

[0015] By adopting the above technical solution, when the user presses the end plate, the end plate moves the locking assembly closer to the central axis of the protective cover via the slide rod. At the same time, the end plate compresses the return spring. When the user releases the end plate, the return spring resets and moves the end plate away from the outer wall of the protective cover, so that the end plate moves the locking assembly away from the central axis of the protective cover via the slide rod.

[0016] Preferably, the reset assembly further includes a telescopic tube, which is sleeved on the reset spring. One end of the telescopic tube is fixedly connected to the rubber layer, and the other end of the telescopic tube is fixedly connected to the outer wall of the protective cover.

[0017] By adopting the above technical solution, the telescopic tube is sleeved on the return spring, thus protecting the return spring.

[0018] Preferably, the snap-fit ​​assembly includes a first snap-fit ​​block, a second snap-fit ​​block, and a connecting block. The connecting block is located between the first snap-fit ​​block and the second snap-fit ​​block. One end of the connecting block is fixedly connected to the first snap-fit ​​block, and the other end of the connecting block is fixedly connected to the second snap-fit ​​block. The first snap-fit ​​block and the slide rod are fixedly connected at one end inside the protective cover. The first snap-fit ​​block and the second snap-fit ​​block are arranged opposite to each other, and a snap-fit ​​gap is formed between the first snap-fit ​​block and the second snap-fit ​​block.

[0019] By adopting the above technical solution, the sliding rod moves and drives the first locking block, the second locking block and the connecting block to move synchronously, thereby forming a locking gap between the first locking block and the second locking block and moving along the radial direction of the protective cover. When the insertion ring is inserted into the locking gap between the first locking block and the second locking block, the first locking block and the second locking block limit the insertion ring.

[0020] Preferably, the second snap-fit ​​block has a snap-fit ​​inclined surface on the side wall away from the central axis of the protective cover, the snap-fit ​​inclined surface penetrates the side wall of the second snap-fit ​​block, and the inner ring wall of the insertion ring has an abutting inclined surface, the abutting inclined surface penetrates the end wall of the insertion ring, the abutting inclined surface is used to abut against the snap-fit ​​inclined surface.

[0021] By adopting the above technical solution, during the process of inserting the installation ring into the protective cover, the insertion ring uses the mutually fitting abutting inclined surface and the snapping inclined surface to push the second snapping block closer to the central axis of the protective cover. When the abutting inclined surface and the snapping inclined surface separate, the reset component drives the snapping gap away from the central axis of the protective cover, so that the insertion ring is inserted into the snapping gap, and the protective cover is connected to the main body of the testing equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a protective cover, mounting ring, plug-in ring, through hole, slide rod, reset component, snap-fit ​​component, and snap-fit ​​gap, when the protective cover is separated from the testing equipment body, the user continuously presses the slide rod with one hand. The slide rod drives the snap-fit ​​component to move, causing the plug-in ring and snap-fit ​​gap to separate. On the one hand, the plug-in ring and snap-fit ​​gap are kept separated, and on the other hand, the protective cover is clamped and fixed. The user fixes the testing equipment body with the other hand, and then moves the protective cover away from the testing equipment body to remove the protective cover. Although the volume of the slide rod outside the protective cover is small, the user only needs to press the slide rod to facilitate the removal of the protective cover. 2. By setting a return spring, the sliding rod is positioned so that one end inside the protective cover is close to the inner wall of the protective cover; 3. By setting a first snap-fit ​​block, a second snap-fit ​​block, and a connecting block, a snap-fit ​​gap is formed between the first snap-fit ​​block and the second snap-fit ​​block.

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a power detection and protection device. (Refer to...) Figure 1 and Figure 2The system includes a protective cover 1 with a set of through holes 11. A sliding rod 3 is inserted into each through hole 11 and slidably connected to the through hole 11. A locking assembly 5 is installed on one end of the sliding rod 3 inside the protective cover 1, forming a locking gap 6. A reset assembly 4 is installed between the sliding rod 3 and the protective cover 1, bringing the locking gap 6 closer to the inner wall of the protective cover 1. When the user presses the sliding rod 3, the sliding rod 3 moves the locking assembly 5, bringing the locking gap 6 closer to the central axis of the protective cover 1. When the user releases the sliding rod 3, the sliding rod 3, under the action of the reset assembly 4, moves the locking assembly 5, moving the locking gap 6 away from the central axis of the protective cover 1. A mounting ring 2 is inserted into the protective cover 1 and is mounted on the detection equipment body 7. A plug-in ring 21 is installed on the inner wall of the mounting ring 2, which is inserted into the locking gap 6. When the protective cover 1 is used to shield the detection end of the testing device body 7, the detection end of the testing device body 7 is inserted into the protective cover 1, and the locking gap 6 is brought close to the central axis of the protective cover 1 until the insertion ring 21 is aligned with the locking gap 6. At this time, the reset component 4 moves the locking gap 6 away from the central axis of the protective cover 1, so that the insertion ring 21 is inserted into the locking gap 6. At this time, the protective cover 1 is fitted on the mounting ring 2 and the insertion ring 21 is inserted into the locking gap 6, so that the protective cover 1 is connected to the testing device body 7 and shields the detection end of the testing device body 7. When separating the protective cover 1 from the testing device body 7, the user keeps pressing the slide bar 3 with one hand. The slide bar 3 moves the locking component 5 to separate the insertion ring 21 from the locking gap 6. On the one hand, the insertion ring 21 is kept separated from the locking gap 6, and on the other hand, the protective cover 1 is clamped and fixed. The user fixes the testing device body 7 with the other hand, and then moves the protective cover 1 away from the testing device body 7 to remove the protective cover 1. Although the slider 3 is small in size and located outside the protective cover 1, the user can easily remove the protective cover 1 by simply pressing the slider 3.

[0028] To facilitate users in continuously pressing slider 3 with one hand, refer to... Figure 1 and Figure 2 The through holes 11 are positioned opposite each other. An end plate 31 is installed at one end of the slide rod 3 outside the protective cover 1. The outer wall of the end plate 31 is covered with a rubber layer 32, which is connected to the reset assembly 4. The end plate 31 increases the contact area between the slide rod 3 and the hand, and the rubber layer 32 increases the friction of the end plate 31, making it easier for the user to continuously press the slide rod 3 with one hand.

[0029] Reference Figure 1 and Figure 2The reset assembly 4 includes a reset spring 41 and a telescopic tube 42. The reset spring 41 is sleeved on the slide rod 3, and the telescopic tube 42 is sleeved on the reset spring 41, providing protection for the reset spring 41. One end of the reset spring 41 and one end of the telescopic tube 42 are fixedly connected to the rubber layer 32, and the other end of the reset spring 41 and the other end of the telescopic tube 42 are fixedly connected to the outer wall of the protective cover 1. When the user presses the end plate 31, the end plate 31, through the slide rod 3, drives the locking assembly 5 closer to the central axis of the protective cover 1, while simultaneously compressing the reset spring 41 and the telescopic tube 42. When the user releases the end plate 31, the reset spring 41 resets, causing the end plate 31 to move away from the outer wall of the protective cover 1, and the end plate 31, through the slide rod 3, drives the locking assembly 5 away from the central axis of the protective cover 1.

[0030] Reference Figure 1 and Figure 2 The snap-fit ​​assembly 5 includes a first snap-fit ​​block 51, a second snap-fit ​​block 52, and a connecting block 53. The connecting block 53 is located between the first snap-fit ​​block 51 and the second snap-fit ​​block 52. One end of the connecting block 53 is welded to the first snap-fit ​​block 51, and the other end of the connecting block 53 is welded to the second snap-fit ​​block 52. The first snap-fit ​​block 51, the second snap-fit ​​block 52, and the connecting block 53 together form a U-shaped structure. The side of the first snap-fit ​​block 51 away from the central axis of the protective cover 1 is welded to the end of the slide rod 3 located inside the protective cover 1. The first snap-fit ​​block 51 and the second snap-fit ​​block 52 are arranged opposite to each other, forming a snap-fit ​​gap 6 between them. The movement of the slide rod 3 causes the first snap-fit ​​block 51, the second snap-fit ​​block 52, and the connecting block 53 to move synchronously, thereby causing the first snap-fit ​​block 51 and the second snap-fit ​​block 52 to move along the radial direction of the protective cover 1, forming the snap-fit ​​gap 6. When the insertion ring 21 is inserted into the locking gap 6 between the first locking block 51 and the second locking block 52, the first locking block 51 and the second locking block 52 limit the insertion ring 21.

[0031] Reference Figure 1 and Figure 2 The second snap-fit ​​block 52 has a snap-fit ​​inclined surface 61 on its side wall away from the central axis of the protective cover 1, and the snap-fit ​​inclined surface 61 penetrates the side wall of the second snap-fit ​​block 52. The inner ring wall of the insertion ring 21 has an abutment inclined surface 62, and the abutment inclined surface 62 penetrates the end wall of the insertion ring 21. The inclination of the abutment inclined surface 62 is the same as the inclination of the snap-fit ​​inclined surface 61, and the abutment inclined surface 62 is used to abut against the snap-fit ​​inclined surface 61. During the process of inserting the mounting ring 2 into the protective cover 1, when the abutment inclined surface 62 and the snap-fit ​​inclined surface 61 are in contact, the insertion ring 21 pushes the second snap-fit ​​block 52 closer to the central axis of the protective cover 1. When the abutment inclined surface 62 and the snap-fit ​​inclined surface 61 separate, the reset component 4 moves the snap-fit ​​gap 6 away from the central axis of the protective cover 1, so that the insertion ring 21 is inserted into the snap-fit ​​gap 6, and the protective cover 1 is connected to the detection equipment body 7.

[0032] The implementation principle of the power detection and protection device in this application embodiment is as follows: When the detection end of the detection equipment body 7 is shielded and protected by the protective cover 1, the detection end of the detection equipment body 7 is inserted into the protective cover 1. After the abutting inclined surface 62 on the insertion ring 21 is in contact with the locking inclined surface 61 on the second locking block 52, the insertion ring 21 continues to move, pushing the second locking block 52 closer to the central axis of the protective cover 1. After the abutting inclined surface 62 separates from the locking inclined surface 61, the return spring 41 drives the locking gap 6 away from the central axis of the protective cover 1, so that the insertion ring 21 is inserted into the locking gap 6. The first locking block 51 and the second locking block 52 limit the insertion ring 21, realizing the effect of connecting the protective cover 1 and the detection equipment body 7, while the protective cover 1 shields and protects the detection end of the detection equipment body 7. When separating the protective cover 1 from the main body 7 of the testing equipment, the user holds the main body 7 of the testing equipment with one hand and continuously presses the end plate 31 with the other hand. This keeps the insertion ring 21 separated from the locking gap 6 and clamps and fixes the protective cover 1. Then, the protective cover 1 and the main body 7 are moved away from each other, thus removing the protective cover 1. Although the slide bar 3 is small in size at the section outside the protective cover 1, the user only needs to press the slide bar 3 to easily remove the protective cover 1.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
