Description

Technical Field

[0001] This utility model belongs to the technical field of data acquisition device housing, and more specifically, it relates to a mechanical locking structure for data acquisition device housing. Background Technology

[0002] The data acquisition unit housing refers to the external structure used to enclose and protect the internal electronic components and circuits of the data acquisition unit. Its main function is to provide physical protection and prevent external environmental factors from damaging the internal circuits and components.

[0003] Currently, the housing of some data acquisition devices requires multiple screws to be fixed during the installation of the housing cover, and special screw tightening tools must be carried. This not only makes the disassembly process laborious, but also makes carrying special tools quite inconvenient, thus significantly reducing the ease of use of the device.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a mechanical locking structure for the data acquisition device housing, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mechanical locking structure for the housing of a data acquisition device, which is achieved by the following specific technical means: The mechanical locking structure of the data acquisition device housing includes a housing and a cover. The upper ends of the inner walls on both sides of the housing are provided with several slots. A connecting block is installed on the bottom surface of the cover. A mounting groove is provided in the middle of the connecting block. Several locking pins are movably connected to both sides of the mounting groove. The number of locking pins is equal to the number of slots, and the size of one end of each locking pin matches the size of the slot. One end of each locking pin extends to the outside of the connecting block, and a mounting plate is installed at the other end. A rotating shaft is rotatably connected to the bottom surface of the cover. The bottom end of the rotating shaft extends into the mounting groove and is fitted with a gear. A pair of racks are meshed on both sides of the gear. One end of each pair of racks is fixedly connected to one side of a pair of mounting plates. A rotating component is installed above the rotating shaft on the upper surface of the cover.

[0006] Furthermore, a threaded groove is provided at the middle position of the upper end face of the shell cover, and the top end of the rotating shaft extends into the threaded groove.

[0007] Furthermore, the upper end face of the rotating shaft is provided with a hexagonal groove.

[0008] Furthermore, the rotating component includes a rotating block and a threaded sleeve, the rotating block being mounted on the upper end face of the threaded sleeve, and the threaded sleeve matching the threaded groove.

[0009] Furthermore, the upper end face of the rotating block is provided with a groove, and a hexagonal block is installed at the bottom of the groove. The inner diameter of the groove is larger than the outer diameter of the rotating shaft, and the size of the hexagonal block matches the size of the hexagonal groove.

[0010] Furthermore, the bottom end face of the threaded sleeve is provided with a second groove, the inner diameter of which matches the outer diameter of the rotating shaft.

[0011] Furthermore, a cover plate is installed at the bottom of the mounting slot by screws.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By using a combination of rotating parts, a rotating shaft, gears, racks, locking pins, and slots, the operator first inserts the connecting block at the bottom of the cover into the slot at the top of the housing. Then, the rotating part is rotated counterclockwise to disengage it from the threaded groove. Next, the hexagonal block is embedded into the hexagonal slot at the top of the rotating shaft. The rotating part drives the rotating shaft to rotate, which in turn drives the gear to rotate. Since the gear meshes with a pair of racks, when the gear rotates, it drives the racks to move to both sides. The racks push multiple locking pins into the slots through the mounting plate, thus completing the connection between the cover and the housing. Then, the rotating part is removed, and its bottom end is tightened into the threaded groove. During the tightening process, the top of the second groove presses against the top of the rotating shaft, fixing the rotating shaft. At this time, the cover is fixed to the upper surface of the housing, thus achieving the effect of quick installation and removal of the cover, thereby improving the convenience of the device.

[0024] Example: As attached Figure 1 To be continued Figure 7 As shown: This utility model provides a mechanical locking structure for the housing of a data acquisition device, including a housing 1 and a cover 2. The upper ends of the inner walls on both sides of the housing 1 are provided with several slots 101. A connecting block 3 is installed on the bottom end face of the cover 2. A mounting groove 301 is provided in the middle of the connecting block 3. Several locking pins 401 are movably connected to both sides of the mounting groove 301. The number of locking pins 401 is equal to the number of slots 101, and the size of one end of the locking pin 401 matches the size of the slot 101. One end of the locking pin 401 extends to the outside of the connecting block 3, and a mounting plate 4 is installed on the other end of the locking pin 401. A rotating shaft 5 is rotatably connected to the bottom end face of the cover 2. The bottom end of the rotating shaft 5 extends into the mounting groove 301 and is equipped with a gear 501. A pair of racks 402 are meshed on both sides of the gear 501. One end of the pair of racks 402 is fixedly connected to one side of the pair of mounting plates 4 respectively. A rotating component 6 is installed on the upper end face of the cover 2 above the rotating shaft 5.

[0025] The upper end face of the cover 2 is provided with a threaded groove 201 in the middle position, and the top end of the rotating shaft 5 extends into the threaded groove 201.

[0026] The upper end face of the rotating shaft 5 is provided with a hexagonal groove 502.

[0027] The rotating component 6 includes a rotating block 601 and a threaded sleeve 602. The rotating block 601 is installed on the upper end face of the threaded sleeve 602, and the threaded sleeve 602 is matched with the threaded groove 201.

[0028] The upper end face of the rotating block 601 is provided with a groove 603. A hexagonal block 605 is installed at the bottom of the groove 603. The inner diameter of the groove 603 is larger than the outer diameter of the rotating shaft 5. The size of the hexagonal block 605 matches the size of the hexagonal slot 502. The hexagonal block 605 is embedded in the hexagonal slot 502 at the top of the rotating shaft 5. The rotating component 6 drives the rotating shaft 5 to rotate, which in turn drives the gear 501 to rotate. Since the gear 501 meshes with a pair of racks 402, when the gear 501 rotates, it drives the racks 402 to move to both sides. The racks 402 push multiple locking pins 401 into the slots 101 through the mounting plate 4.

[0029] The bottom end face of the threaded sleeve 602 is provided with a second groove 604. The inner diameter of the second groove 604 matches the outer diameter of the rotating shaft 5. When the threaded sleeve 602 is tightened into the threaded groove 201, the top of the second groove 604 presses against the top of the rotating shaft 5 during the tightening process, thus fixing the rotating shaft 5.

[0030] The bottom of the mounting slot 301 is fitted with a cover plate 302 by screws, which can protect the gear 501 and the rack 402.

[0031] The working principle of this embodiment: First, the worker inserts the connecting block 3 at the bottom of the cover 2 into the groove at the top of the housing 1. Then, the worker rotates the rotating part 6 counterclockwise to disengage it from the threaded groove 201. Next, the worker inserts the hexagonal block 605 into the hexagonal groove 502 at the top of the rotating shaft 5. The rotating part 6 drives the rotating shaft 5 to rotate, which in turn drives the gear 501 to rotate. Since the gear 501 meshes with a pair of racks 402, when the gear 501 rotates, it drives the racks 402 to move to both sides. The racks 402 push multiple locking pins 401 into the locking groove 101 through the mounting plate 4, thus completing the connection between the cover 2 and the housing 1. Then, the worker takes out the rotating part 6 and tightens its bottom end into the threaded groove 201. During the tightening process, the top of the groove 604 presses against the top of the rotating shaft 5, fixing the rotating shaft 5.
