Description

Technical Field

[0001] This utility model relates to the field of fuse cover installation technology, and in particular to a fuse cover that is easy to install. Background Technology

[0002] A fuse is a protective device that protects a circuit from overload. Fuses need to be installed inside the circuit device to be used. They are installed inside the circuit device through a fuse cover, so that the fuse can perform its protective function.

[0003] In the prior art, patent CN 220543826 U discloses a fuse cover that is easy to install. During operation, the spring is made of elastic material. After the fuse is installed inside the first fuse mounting slot, the fuse cover body moves inside the storage slot via a fixing post. The movement of the fixing post drives a rotating shaft and a fixing plate to move towards the storage plate. The guide plate's sidewall near the fixing plate presses against the sidewall of the fixing plate near the guide plate, causing the fixing plate to tilt downwards via the rotating shaft and enter the storage slot near the second friction plate. When the fuse cover body moves, the inner walls of the first and second friction plates eventually rub against each other and become fixed. Because the spring itself is elastic, the fixing sleeve presses against one sidewall of the fixing plate, causing the sidewalls of the first and second fuse mounting slots to fit together and become fixed. This completes the installation of the fuse cover body and the circuit device. However, the fuse generates high temperatures during operation, which can adversely affect the spring's performance, leading to an increased failure rate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fuse cover that is easy to install and disassemble, avoiding the drawbacks of using a spring mechanism, thereby ensuring the smooth operation of the installation structure and effectively solving the problems in the background art.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0006] A fuse cover that is easy to install includes a fuse box. The top of the fuse box is connected to the fuse cover via a positioning mechanism. A driving mechanism is installed on the fuse cover. A fixing unit for connecting and fixing with the fuse box is installed on the driving part of the driving mechanism.

[0007] Furthermore, the positioning mechanism includes a positioning hole and a positioning rod. The positioning hole is opened on the fuse box, and the positioning rod is fixed to the bottom of the fuse cover plate. The positioning rod is inserted into the positioning hole.

[0008] Furthermore, the drive mechanism includes a slide groove and a transmission seat, the slide groove being formed on the fuse cover plate, and the transmission seat being slidably connected to the slide groove.

[0009] Furthermore, the drive mechanism also includes a bidirectional lead screw, which is rotatably mounted on the inner side of the slide groove. The bidirectional lead screw is threadedly connected to the transmission seat, and the middle part of the bidirectional lead screw is a smooth rod structure.

[0010] Furthermore, the drive mechanism also includes a slide rail, a knob, a lock hole, and a locking rod. The slide rail is fixed on the guide rod of the bidirectional lead screw. The knob is slidably connected to the guide rod of the bidirectional lead screw through the slide rail. The lock holes are evenly distributed on the knob. The locking rod is fixed on the side of the fuse box and is set in a one-to-one correspondence with the lock holes. The locking rod and the lock hole are engaged and inserted into each other.

[0011] Furthermore, the fixing unit includes a plug and a socket. The plug is fixed to the side of the transmission seat, and the socket is opened on the fuse box. The plug and the socket are connected to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-install fuse cover has the following advantages: the fixed unit is moved by the drive mechanism, thereby fixing the fuse cover on the fuse box. Its installation and disassembly are convenient, avoiding the drawbacks of using a spring mechanism, thus ensuring the smooth operation of the installation structure.

Detailed Implementation

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Please see Figure 1-4 This embodiment provides a technical solution: a fuse cover that is easy to install, including a fuse box 1. The top of the fuse box 1 is connected to a fuse cover 2 via a positioning mechanism 3. A driving mechanism 5 is installed on the fuse cover 2. A fixing unit 4 for connecting and fixing with the fuse box 1 is installed on the driving part of the driving mechanism 5.

[0020] The positioning mechanism 3 includes a positioning hole 31 and a positioning rod 32. The positioning hole 31 is opened on the fuse box 1, and the positioning rod 32 is fixed to the bottom of the fuse cover 2. The positioning rod 32 is engaged with the positioning hole 31, thereby fastening the fuse cover 2 to the top of the fuse box 1. The positioning facilitates the subsequent fixing of the fixing unit 4.

[0021] The drive mechanism 5 includes a slide groove 51 and a transmission seat 53. The slide groove 51 is formed on the fuse cover plate 2, and the transmission seat 53 is slidably connected to the slide groove 51. The drive mechanism 5 also includes a bidirectional lead screw 52, ​​which is rotatably mounted on the inner side of the slide groove 51 and threadedly connected to the transmission seat 53. The middle part of the bidirectional lead screw 52 is a smooth rod structure. The drive mechanism 5 also includes a slide rail 54, a knob 55, a locking hole 56, and a locking rod 57. The slide rail 54 is fixed on the smooth rod of the bidirectional lead screw 52. The knob 55 is slidably connected to the smooth rod of the bidirectional lead screw 52 through the slide rail 54. The locking holes 56 are evenly formed on the knob 55. The locking rod 57 is fixed on the side of the fuse box 1 and is set one-to-one with the locking holes 56. The locking rod 57 is inserted into the locking holes 56. The fixing unit 4 includes a plug 41 and a socket 42. The plug 41 is fixed to the transmission seat. On the side of 53, the socket 42 is opened on the fuse box 1. The plug 41 is inserted into the socket 42. Rotating the knob 55 drives the double-acting screw 52 to rotate. The double-acting screw 52 is threadedly driven by the transmission seat 53. The transmission seat 53 slides along the slide groove 51. The plug 41 on the transmission seat 53 is inserted into the socket 42 on the fuse box 1, thereby fixing the fuse cover 2 on the fuse box 1. Then, turning the knob 55 causes the knob 55 to slide relative to the smooth rod of the double-acting screw 52 through the slide rail 54 until the locking rod 57 on the fuse box 1 is inserted into the locking hole 56 on the knob 55. The locking prevents the knob 55 from being accidentally turned, thus ensuring the safety of use. Its installation and disassembly are convenient, avoiding the drawbacks of using a spring mechanism, thus ensuring the smooth operation of the installation structure.

[0022] The working principle of the fuse cover plate that is easy to install provided by this utility model is as follows: The positioning rod 32 is engaged with the positioning hole 31 to fasten the fuse cover plate 2 to the top of the fuse box 1. Then, the knob 55 is rotated, which drives the bidirectional screw 52 to rotate. The bidirectional screw 52 is threadedly driven by the transmission seat 53. The transmission seat 53 slides along the slide groove 51. The plug 41 on the transmission seat 53 is inserted into the insertion hole 42 on the fuse box 1, thereby fixing the fuse cover plate 2 on the fuse box 1. Then, the knob 55 is turned, and the knob 55 slides relative to the smooth rod of the bidirectional screw 52 through the slide rail 54 until the locking rod 57 on the fuse box 1 is inserted into the locking hole 56 on the knob 55.
