Description

Technical Field

[0001] This invention relates to the field of ship clock frame technology, specifically to a height-adjustable ship clock frame. Background Technology

[0002] A ship's clock rack is a specialized support device used on ships to fix and support ship's clocks. It ensures that the timekeeping instrument remains stable and level in the turbulent environment at sea, so as to maintain high-precision timekeeping function. The ship's clock rack is specifically designed to install ship's clocks. It uses mechanical structures (such as a universal joint system) to counteract the effects of the ship's swaying and vibration, prevent water damage and displacement, and ensure the continuous and accurate operation of the clock. Its core is to support the ship's porthole clock or astronomical clock. These clocks require strong anti-interference, low temperature coefficient and durability.

[0003] Existing ship clock racks have certain shortcomings in practical use: they lack a height adjustment structure, which requires crew members of different heights to use other tools when hanging the clock, increasing the complexity of the operation. At the same time, fixed-height ship clock racks cannot adjust the center of gravity position according to changes in ship load. Based on the shortcomings of existing technology, this invention designs a height-adjustable ship clock rack. Summary of the Invention

[0004] The present invention provides a height-adjustable ship clock tower, which has the advantage of adjustable ship clock tower height and solves the problems mentioned in the background art above.

[0005] The present invention provides the following technical solution: a height-adjustable ship clock frame, comprising a fixed frame plate, a height adjustment structure fixedly installed on the top of the fixed frame plate, the height adjustment structure comprising a frame rod; a first hinge seat fixedly installed on one side of the outer surface of the frame rod, a crossbar hingedly installed inside the first hinge seat, a clock buckle fixedly installed at the end of the crossbar, two support plates fixedly installed on one side of the outer surface of the frame rod, a threaded rod rotatably installed between the two support plates, a threaded block threadedly installed on the outer surface of the threaded rod, a second hinge seat hingedly installed on the outer surface of the threaded block, a connecting rod fixedly installed on one side of the second hinge seat, and a third hinge seat fixedly installed at one end of the connecting rod.

[0006] As a preferred embodiment of the present invention, reinforcing rods are fixedly installed on both sides of the outer surface of the frame pole, and the two reinforcing rods are fixedly connected to the fixed frame plate.

[0007] As a preferred embodiment of the present invention, a first handwheel is fixedly installed at one end of the threaded rod that passes through the support plate, and the third hinge seat is hinged to the crossbar.

[0008] As a preferred embodiment of the present invention, two mounting grooves are provided on both sides of the outer surface of the fixed frame plate, and a movable structure is fixedly installed inside the mounting grooves on both sides.

[0009] As a preferred embodiment of the present invention, the two movable structures include two folding blocks and two second fixed frames. The two folding blocks are rotatably connected to the mounting groove, and a connecting plate is fixedly installed on one side of each of the two folding blocks.

[0010] As a preferred embodiment of the present invention, movable wheels are rotatably mounted on both sides of the top of the two connecting plates, and a first fixing frame is fixedly mounted on the top of the two connecting plates.

[0011] As a preferred embodiment of the present invention, insert plates are slidably installed inside the two second fixed frames, and abutment plates are fixedly installed at one end of the two insert plates.

[0012] As a preferred embodiment of the present invention, a counterweight structure is fixedly installed on the top of the fixed frame plate. The counterweight structure includes a mounting plate, and a counterweight plate is placed inside the mounting plate.

[0013] As a preferred embodiment of the present invention, a fixing plate is fixedly installed on the top of the counterweight plate, and the fixing plate is fixedly connected to the mounting plate by bolts. A sliding groove is provided inside the counterweight plate.

[0014] As a preferred embodiment of the present invention, a sliding block is slidably installed inside the slide groove, a fastening bolt is installed inside the sliding block, a second handwheel is fixedly installed on the top of the fastening bolt, and a placement frame is fixedly installed on both sides of the outer surface of the sliding block, with a counterweight placed inside the two placement frames.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This height-adjustable ship clock rack, through its height adjustment structure, allows the operator to rotate the first handwheel according to their height when the ship clock is hung on the clock buckle. This causes the threaded rod to rotate, and due to the limiting effect of the second hinge seat on the threaded block, the threaded block can move horizontally up and down on the outer surface of the threaded rod. Since the second and third hinge seats are connected by a connecting rod, when the threaded block moves the second hinge seat up and down, the connecting rod can pull the third hinge seat. Because the third hinge seat is hinged to the crossbar, the crossbar can be folded around the first hinge seat, thereby adjusting the height of the clock buckle. This achieves the purpose of adjustable ship clock rack height, suitable for crew members of different heights. It also allows for dynamic adjustment of the ship clock position according to the ship's load status, avoiding the ship's center of gravity from rising due to the clock being too high.

[0017] 2. This height-adjustable ship's clock frame, through a movable structure, allows the connecting plates on both sides to fold down in the normal state, with the insert plate inserted into the first fixed frame. At this time, the fixed frame plate cannot be moved. When the device needs to be moved, the abutment plate is pulled to pull the insert plate out of the first fixed frame. Then, the two connecting plates are folded down to make the moving wheels contact the ground, and the device can be moved. It can be quickly transferred to a low-vibration position (such as the foredeck) to avoid high-frequency vibration sources such as the engine room, reducing the risk of damage to the mechanism. At the same time, it can avoid the problem of obstructing the view of navigation instruments or emergency passages, ensuring unimpeded execution of emergency operations.

[0018] 3. This height-adjustable ship clock frame, through the counterweight structure, after adjusting the height of the height adjustment structure and hanging the ship clock on the clock buckle, the counterweight plate is fixed inside the mounting plate by the fixing plate. Then, the sliding block is installed inside the slide groove. The position of the sliding block in the slide groove is adjusted according to the height of the ship clock. After it is determined, the second handwheel is turned to move the fastening bolt in the sliding block downward to abut against the counterweight plate and fix it. This can quickly lower the overall center of gravity of the ship clock frame and reduce the risk of rolling and tilting. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 The height-adjustable ship clock frame includes a fixed frame plate 1, a height adjustment structure 2 fixedly installed on the top of the fixed frame plate 1, and a frame rod 21. A first hinge seat 23 is fixedly installed on one side of the outer surface of the frame rod 21. A crossbar 24 is hingedly installed inside the first hinge seat 23. A clock buckle 25 is fixedly installed at the end of the crossbar 24. Two support plates 26 are fixedly installed on one side of the outer surface of the frame rod 21. A threaded rod 27 is rotatably installed between the two support plates 26. A threaded block 29 is threadedly installed on the outer surface of the threaded rod 27. A second hinge seat 210 is hingedly installed on the outer surface of the threaded block 29. A connecting rod 211 is fixedly installed on one side of the second hinge seat 210. A third hinge seat 212 is fixedly installed at one end of the connecting rod 211.

[0029] Please see Figure 2-3 Two reinforcing rods 22 are fixedly installed on both sides of the outer surface of the support rod 21, and the two reinforcing rods 22 are fixedly connected to the fixed frame plate 1. The first handwheel 28 is fixedly installed at one end of the threaded rod 27 that passes through the support plate 26, and the third hinge seat 212 is hinged to the crossbar 24.

[0030] Rotate the first handwheel 28 to drive the threaded rod 27 to rotate. Due to the limiting of the threaded block 29 by the second hinge seat 210, the threaded block 29 can move horizontally up and down on the outer surface of the threaded rod 27.

[0031] Please see Figure 4-5Two mounting slots 3 are formed on both sides of the outer surface of the fixed frame plate 1. Movable structures 4 are fixedly installed inside the mounting slots 3. The two movable structures 4 include two folding blocks 41 and two second fixed frames 45. The two folding blocks 41 are rotatably connected to the mounting slots 3, and a connecting plate 42 is fixedly installed on one side of each folding block 41. Moving wheels 43 are rotatably mounted on the top sides of the two connecting plates 42, and a first fixed frame 44 is fixedly installed on the top of the two connecting plates 42. Insert plates 46 are slidably installed inside the two second fixed frames 45, and a stop plate 47 is fixedly installed at one end of each insert plate 46.

[0032] The two connecting plates 42 are folded over, and the insert plate 46 is inserted into the first fixed frame 44. At this time, the fixed frame plate 1 cannot be moved. When the device needs to be moved, the insert plate 46 is pulled out from the first fixed frame 44 by pulling the abutment plate 47. At this time, the two connecting plates 42 are folded down so that the moving wheel 43 contacts the ground, and the device can be moved.

[0033] Please see Figure 6-7 A counterweight structure 5 is fixedly installed on the top of the fixed frame plate 1. The counterweight structure 5 includes a mounting plate 51, and a counterweight plate 52 is placed inside the mounting plate 51. A fixing plate 53 is fixedly installed on the top of the counterweight plate 52. The fixing plate 53 is fixedly connected to the mounting plate 51 by bolts. A sliding groove 54 is opened inside the counterweight plate 52. A sliding block 55 is slidably installed inside the sliding groove 54. A fastening bolt 56 is threaded inside the sliding block 55. A second handwheel 57 is fixedly installed on the top of the fastening bolt 56. Placement racks 58 are fixedly installed on both sides of the outer surface of the sliding block 55. Counterweight blocks 59 are placed inside the two placement racks 58.

[0034] After adjusting the height of the height adjustment structure 2 and hanging the ship's clock on the clock buckle 25, the counterweight plate 52 is fixed inside the mounting plate 51 by the fixing plate 53. Then, the sliding block 55 is installed inside the slide groove 54. The position of the sliding block 55 in the slide groove 54 is adjusted according to the height of the ship's clock. After it is determined, the fastening bolt 56 is moved downward in the sliding block 55 by rotating the second handwheel 57 to press against the counterweight plate 52 and fix it. This can quickly lower the overall center of gravity of the ship's clock frame and reduce the risk of rolling and tilting.

[0035] Working principle: When the height-adjustable ship's clock frame is in use, in its normal state, the connecting plates 42 on both sides are folded down, and the insert plate 46 is inserted into the first fixed frame 44. At this time, the fixed frame plate 1 cannot be moved. When the device needs to be moved, the abutment plate 47 is pulled to pull the insert plate 46 out of the first fixed frame 44. Then, the two connecting plates 42 are folded down so that the moving wheel 43 contacts the ground, and the device can be moved. When the ship's clock is hung on the clock buckle 25, the operator can turn the first handwheel 28 according to their height, which will drive the threaded rod 27 to rotate. Due to the limitation of the threaded block 29 by the second hinge seat 210, the threaded block 29 can move horizontally up and down on the outer surface of the threaded rod 27. Since the second hinge seat 210 and the third hinge seat 212 are connected by the connecting rod 211, When the threaded block 29 drives the second hinge seat 210 to move up and down, the connecting rod 211 can pull the third hinge seat 212. Since the third hinge seat 212 is hinged to the crossbar 24, the crossbar 24 can be folded around the first hinge seat 23, thereby adjusting the height of the clock buckle 25. After adjusting the height of the height adjustment structure 2, the ship clock is hung on the clock buckle 25. The counterweight plate 52 is fixed inside the mounting plate 51 by the fixing plate 53. Then, the sliding block 55 is installed inside the slide groove 54. The position of the sliding block 55 in the slide groove 54 is adjusted according to the height of the ship clock. After it is determined, the fastening bolt 56 is moved downward in the sliding block 55 by rotating the second handwheel 57 to abut against the counterweight plate 52 and fix it. This can quickly lower the overall center of gravity of the ship clock frame and reduce the risk of rolling and tilting.
