Description

Technical Field

[0001] The present invention relates to the technical field of lock rod devices, and particularly to a container door lock rod device. Background Art

[0002] The lock rod device is also known as a latch, door lock, etc. With its good compressive resistance and stable effect, the lock rod device can be applied to various fields such as automobiles, civil use, and containers. When a container is in transportation operation, it is necessary to lock the container door to meet the need for the interior of the container to be in a sealed state, which is convenient for subsequent long-distance transportation operations of the items or goods stored inside the container. In daily use, a container door lock rod device is needed to perform the locking operation on the container door.

[0003] The existing lock rod devices are often fixedly installed during use, which is not convenient to adjust the installation height position according to the usage requirements, reducing the adjustability of the device installation and also reducing the applicable range of the device, making it inconvenient for users of different heights to perform the locking operation. The existing solution is to equip electrical devices such as threaded feet and electric rods to adjust the installation height position of the device. However, when the device is in use, it does not have the function of automatically maintaining the device. After long-term use of the device, it is easy for the lubricating oil to be exhausted, resulting in problems such as jamming when locking and unlocking, reducing the stable effect of using the device to lock and unlock, shortening the service life of the bolt, and at the same time not having the function of quick locking, which requires the operator to use external equipment to adjust the operating state of the device, increasing the carrying burden of the staff, reducing the efficiency of locking and unlocking, and also complicating the working process of the device operation. Therefore, a container door lock rod device needs to be designed. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a container door lock rod device, which has the function of self-lubricating when unlocking, can recycle the excess lubricating oil, and the door lock has the function of quick locking.

[0005] To achieve the above object, the present invention provides the following technical solution: A container door lock rod device includes a first box, a second box, and a driving mechanism. The driving mechanism is fixedly installed inside the first box. The driving mechanism includes a commutator, and a screw sleeve frame is threadedly installed inside the first box through a screw. A second box is movably installed on one side of the first box, and sliding sleeve seats are installed on the backs of the first box and the second box;

[0006] A lubricating mechanism is fixedly installed at the top inside the second box. The lubricating mechanism includes a piston cylinder. A second one-way valve pipe is fixedly installed on one side of the piston cylinder, and a bypass pipe is also connected to the outlet of the second one-way valve pipe. A through collecting box is fixedly installed at one end of the second one-way valve pipe, and a through first one-way valve pipe is fixedly installed on the second one-way valve pipe through the bypass pipe. A linkage piston rod extending into the piston cylinder is movably installed on the front of the second box through a chute, and a return spring is sleeved outside the linkage piston rod. A high-density brush roller is rotatably installed inside the second box;

[0007] Locking mechanisms are fixedly installed on both sides of the second box. The locking mechanisms include a housing. A support rod is movably installed inside the housing through a contact spring, and a cutter head is fixedly installed at one end of the support rod.

[0008] Due to the high-density characteristic of the high-density brush roller, the lubricating oil stored inside the fuel tank can be absorbed. And due to the relatively small interval between the molecules of the high-density brush roller, the lubricating oil can be prevented from flowing to the outside. After the locking rod that has moved into the second box touches the high-density brush roller, the lubricating oil is smeared on the surface of the locking rod, realizing the automatic lubrication of the locking rod. At the same time, the linkage effect of fixing the locking rod and smearing the lubricating oil is achieved, and the function of automatically maintaining the locking rod is realized, solving the problem that after long-term use of the locking rod, the lubricating oil is exhausted and the unlocking and locking are prone to jamming and abnormal noises, improving the stable effect of unlocking and locking the device during use, and also extending the service life of the locking rod; when the contact spring is subjected to the contact force of the locking rod, it can drive the support rod to retract into the housing. The moving support rod can drive the two cutter heads to move away from both sides of the locking rod. Then, due to the high elastic force of the contact spring, the support rod can be driven to extend out of the housing, and through the design of the inclined surface of the cutter head, it is convenient to move by touching on the outside of the locking rod, so that the cutter head extends into the locking rod, realizing the function of quickly locking the moving position of the locking rod. There is no need for the operator to use external equipment to adjust the operating state of the device, reducing the carrying burden of the staff, improving the unlocking and locking efficiency of the device, and simplifying the working process of the device operation.

[0009] Preferably, a turntable is rotatably installed on the front of the first box, and one side of the turntable is fixedly connected to one side of a commutator through a linkage rod. By manually rotating the turntable, it is convenient to provide a power source for the commutator. The commutator can convert the power of the turntable and drive the face rack to rotate. The rotating face rack can provide power transmission for driving the gear disk to rotate subsequently. The commutator plays a role in power commutation, facilitating the subsequent locking of the device.

[0010] Preferably, a moving groove is formed on one side inside the second box, and plugging grooves are formed on both sides of the moving groove. The moving groove provides a moving space for the locking rod, facilitating its subsequent extension into the second box. The plugging grooves provide a moving space for the subsequent guide rod. The cooperation of the plugging grooves and the guide rod facilitates guiding the locking rod, preventing the deviation of the docking position of the locking rod and ensuring the accuracy of the docking position of the locking rod.

[0011] Preferably, a toothed disc is sleeved and installed on the outer side of the screw rod. A face tooth rod is rotatably installed at the bottom of the commutator, and the face tooth rod is meshed and connected with one side of the toothed disc. The rotating face tooth rod can drive the meshed toothed disc to rotate. The rotating toothed disc can drive the screw rod to rotate. The rotating screw rod provides power transmission for driving the subsequent movement of the screw sleeve frame, facilitating the screw sleeve frame to drive the locking rod to extend into the moving groove.

[0012] Preferably, a locking rod is fixedly installed on one side of the screw sleeve frame, and two guide rods are fixedly installed on the outer side of the locking rod through a cross plate. The moving screw sleeve frame can drive the locking rod to move horizontally. The horizontally moving locking rod can drive the guide rod to move synchronously horizontally through the cross plate. The cooperation of the synchronously horizontally moving guide rod and the locking rod can limit the moving positions of the first box and the second box, and the cooperation of the locking rod and the locking mechanism can fix the installation positions of the first box and the second box.

[0013] Preferably, an oil tank is fixedly installed on one side of the top inside the second box. One end of the oil tank is connected to one end of a high-density brush roller through a three-way pipe. A replenishing port is fixedly installed on the top of the oil tank. The top end of the first one-way valve pipe is connected to one side of the water tank. A connecting pipe 510 is provided between the oil tank 501 and the high-density brush roller 504. The end of the connecting pipe 510 extending into the oil tank 501 is in a vertical state, and the upper end of the connecting pipe 510 is higher than the liquid level of the lubricating oil. The oil tank facilitates storing lubricating oil for the device, facilitating long-term storage of lubricating oil and providing a source of lubricating oil for subsequent lubrication operations on the locking rod. The collecting box facilitates storing the dripping lubricating oil inside the second box. The pipe fittings facilitate transporting the lubricating oil into the high-density brush roller, providing convenience for subsequent lubrication operations on the locking rod.

[0014] Preferably, a pull rod extending out of the inside is movably installed inside the housing, and one end of the pull rod is fixedly connected to one end of a resisting spring through a mounting plate. Manually pulling the pull rod can drive the resisting spring to compress. The elastically deformed resisting spring can drive the cutter head away from the inside of the locking rod through a support rod, realizing the function of releasing the locking position of the locking rod and also achieving the purpose of unlocking.

[0015] Preferably, a sliding rod is movably installed inside the sliding sleeve seat, and docking seats are fixedly installed at both ends of the sliding rod through shaft seats. By manually pushing the first box and the second box, the first box and the second box can move vertically through the sliding sleeve seat along the sliding rod, which plays a role in adjusting the installation height position of the first box and the second box, avoiding the limitation of the installation height position of the device for users of different heights, and expanding the applicable range of the device.

[0016] Preferably, a locking member is threadedly installed on one side of the sliding sleeve seat, and one end of the locking member extends into the sliding sleeve seat. By manually rotating the locking member, one end of the locking member can extend into the sliding sleeve seat, realizing the function of locking the moving positions of the first box and the second box, avoiding the first box and the second box falling off the installation position due to external impact, and ensuring the stable effect of the installation positions of the first box and the second box.

[0017] Preferably, a timer is fixedly installed on one side of the front surface of the first box, and a protective screen is fixedly installed on the top of the front surface of the timer. By the energized operation of the timer, it is convenient for the operator to view the time. The protective screen can prevent the display screen of the timer from being damaged due to external impact, ensuring the safety of the timer and extending the service life of the timer.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Due to the high density of the high-density brush roller, it can absorb the lubricating oil stored inside the fuel tank. And due to the relatively small interval between the molecules of the high-density brush roller, it can prevent the lubricating oil from flowing to the outside. After the locking rod moved into the second box touches the high-density brush roller, the lubricating oil is smeared on the surface of the locking rod, realizing the function of automatically lubricating the locking rod. At the same time, it realizes the linkage effect of fixing the locking rod and smearing the lubricating oil, and realizes the function of automatically maintaining the locking rod, solving the problem that after the long-term use of the locking rod, the lubricating oil is exhausted and it is easy to occur the problems of jamming and abnormal noise when locking and unlocking, improving the stable effect of using the device to lock and unlock, and also extending the service life of the locking rod.

[0020] 2. When the abutting spring is subjected to the abutting force of the locking rod, it can drive the support rod to retract into the shell. The moving support rod can drive the two cutter heads to move away from both sides of the locking rod. Then, due to the high elastic force of the abutting spring, it can drive the support rod to extend out of the shell, and through the design of the inclined surface of the cutter head, it is convenient to move by abutting on the outside of the locking rod, so that the cutter head extends into the locking rod, realizing the function of quickly locking the moving position of the locking rod. There is no need for the operator to use external equipment to adjust the operating state of the device, reducing the carrying burden of the staff, improving the efficiency of locking and unlocking the device, and simplifying the working process of the device operation.

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown in the figure, a container door lock rod device proposed by the present invention includes a first box 1, a second box 2 and a driving mechanism 3. A driving mechanism 3 is fixedly installed inside the first box 1. The driving mechanism 3 includes a commutator 301. A screw sleeve holder 4 is threadedly installed inside the first box 1 through a screw 304. A turntable 101 is rotatably installed on the front of the first box 1. One side of the turntable 101 is fixedly connected to one side of the commutator 301 through a linkage rod;

[0033] One side of the screw sleeve holder 4 is fixedly installed with a locking rod 401. Two guide rods 402 are fixedly installed on the outside of the locking rod 401 through a cross plate 403. A toothed disc 303 is sleeved on the outside of the screw 304. A face rack 302 is rotatably installed at the bottom of the commutator 301. The face rack 302 is meshed with one side of the toothed disc 303. A second box 2 is movably installed on one side of the first box 1. Sliding sleeve seats 7 are installed on the backs of the first box 1 and the second box 2;

[0034] A lubricating mechanism 5 is fixedly installed at the top inside the second box 2. The lubricating mechanism 5 includes a piston cylinder 506. One side of the piston cylinder 506 is fixedly installed with a second one-way valve pipe 507. A bypass pipe is also communicated with the outlet of the second one-way valve pipe 507. A through collecting box 503 is fixedly installed at one end of the second one-way valve pipe 507. The second one-way valve pipe 507 is fixedly installed with a through first one-way valve pipe 502 through the bypass pipe. A linkage piston rod 509 extending into the piston cylinder 506 is movably installed on the front of the second box 2 through a chute. A return spring 508 is sleeved on the outside of the linkage piston rod 509. A high-density brush roller 504 is rotatably installed inside the second box 2;

[0035] Locking mechanisms 6 are fixedly installed on both sides of the second box 2. The locking mechanisms 6 include a housing 601. A support rod 603 is movably installed inside the housing 601 through a contact spring 602. A cutter head 604 is fixedly installed at one end of the support rod 603. A sliding rod 701 is movably installed inside the sliding sleeve seat 7;

[0036] Docking seats are fixedly installed at both ends of the sliding rod 701 through shaft seats. A pull rod 605 extending out of the inside is movably installed inside the housing 601. One end of the pull rod 605 is fixedly connected to one end of the contact spring 602 through a mounting plate. A timer 9 is fixedly installed on one side of the front of the first box 1. A protective screen is fixedly installed at the top of the front of the timer 9.

[0037] Based on the working principle of the container door lock rod device in Embodiment 1: After installing the docking seats at both ends of the sliding rod 701 to the installation position of the container door, then manually pushing the first box 1 and the second box 2, the first box 1 and the second box 2 can move vertically along the sliding rod 701 through the sliding sleeve seat 7, which plays a role in adjusting the installation height position of the first box 1 and the second box 2, avoiding the limitation of the installation height position of the device for users of different heights;

[0038] Then, by the operator rotating the turntable 101, the power of the turntable 101 can be converted through the commutator 301 and drive the face rack 302 to rotate. The rotating face rack 302 provides power transmission for driving the gear disk 303 to rotate subsequently;

[0039] The rotating face rack 302 can drive the meshing-connected gear disk 303 to rotate. The rotating gear disk 303 can drive the screw 304 to rotate. The rotating screw 304 provides power transmission for driving the nut sleeve holder 4 to move position subsequently. The moving nut sleeve holder 4 can drive the locking rod 401 to move horizontally;

[0040] The horizontally moving locking rod 401 can drive the guide rod 402 to move horizontally synchronously through the cross plate 403. The guide rod 402 moving horizontally synchronously and the locking rod 401 are used in cooperation to limit the moving positions of the first box 1 and the second box 2. At the same time, the locking rod 401 moves into the second box 2 and abuts against one side of the cutter head 604;

[0041] The abutting spring 602 can drive the support rod 603 to retract into the housing 601 under the abutting force of the locking rod 401. The moving support rod 603 can drive the two cutter heads 604 away from both sides of the locking rod 401. Then, the high elastic force of the abutting spring 602 can drive the support rod 603 to extend out of the housing 601, and the inclined surface design of the cutter head 604 facilitates the abutting movement on the outside of the locking rod 401, so that the cutter head 604 extends into the locking rod 401, realizing the function of quickly locking the moving position of the locking rod 401 and improving the efficiency of the device's locking and unlocking;

[0042] Due to the high density of the high-density brush roller 504, it can absorb the lubricating oil stored in the fuel tank 501. The locking rod 401 moving into the second box 2 abuts against the high-density brush roller 504. Then, due to the small interval between the molecules of the high-density brush roller 504, it can prevent the lubricating oil from flowing to the outside and smear the lubricating oil on the surface of the locking rod 401, realizing the automatic lubrication of the locking rod 401. At the same time, it achieves the linkage effect of fixing the locking rod 401 and smearing the lubricating oil, realizing the function of automatically maintaining the locking rod 401, improving the stable effect of using the device for locking and unlocking, and also extending the service life of the locking rod 401;

[0043] At the same time, the moving locking rod 401 abuts against the linkage piston rod 509 to move. The moving linkage piston rod 509 can apply a pressure value to the inside of the piston cylinder 506, making the inside of the piston cylinder 506 in a negative pressure state. The piston cylinder 506 in a negative pressure state then absorbs the lubricating oil stored in the collection box 503 into the piston cylinder 506 through the second one-way valve pipe 507;

[0044] The timer 9 adopts the NE555DT model, which has the characteristics of dual-module timing, so that the operator can watch the time. When the container door needs to be opened, the pull rod 605 can be manually pulled to drive the resistance spring 602 to be compressed. The resistance spring 602 that undergoes elastic deformation can drive the cutter head 604 away from the inside of the locking rod 401 through the support rod 603, thereby releasing the locking position of the locking rod 401 and achieving the purpose of unlocking.

[0045] When the locking rod 401 is away from the interior of the second box 2, the high elastic force of the return spring 508 can drive the linkage piston rod 509 to move to the reverse horizontal position. The linkage piston rod 509 that moves to the reverse horizontal position can apply pressure to the inside of the piston cylinder 506, so that the lubricating oil stored and collected inside the piston cylinder 506 passes through the front end of the second one-way valve tube 507 and is transported to the interior of the oil tank 501 through the first one-way valve tube 502, and the first one-way valve tube 502 can prevent the lubricating oil from entering the collection box 503 through the first one-way valve tube 502, thereby achieving the function of locking and linking to recover the lubricating oil.

[0046] Embodiment 2

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, a container door lock rod device proposed by the present invention, compared with the first embodiment, this embodiment also includes: a movable groove 201 is opened on one side of the interior of the second box 2, and plug-in grooves are opened on both sides of the movable groove 201, an oil tank 501 is fixedly installed on one side of the top of the interior of the second box 2, one side of the oil tank 501 is connected with one end of a high-density brush roller 504 through a three-way pipe, a replenishing port 505 is fixedly installed on the top of the oil tank 501, and the top of the first one-way valve pipe 502 is connected with one side of the water tank 501, a connecting pipe 510 is arranged between the oil tank 501 and the high-density brush roller 504, and one end of the connecting pipe 510 extending to the interior of the oil tank 501 is in a vertical state, and the upper end of the connecting pipe 510 is higher than the liquid level of the lubricating oil, and a locking member 8 is threadedly installed on one side of the sliding sleeve seat 7, and one end of the locking member 8 extends to the interior of the sliding sleeve seat 7.

[0048] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, the moving groove 201 can provide a moving space for the locking rod 401, so that it can be extended to the inside of the second box 2 through the moving groove 201. The plug-in groove can provide a moving space for the subsequent guide rod 402. The plug-in groove and the guide rod 402 can be used together to provide a guide for the locking rod 401, so as to avoid the locking rod 401 from being offset from the docking position, thereby ensuring the accuracy of the docking position of the locking rod 401.

[0049] As Figure 6 shown, the fuel tank 501 facilitates the storage of lubricating oil for the device, facilitating the long-term storage of lubricating oil and providing a source of lubricating oil for subsequent lubrication operations on the locking lever 401. The collection box 503 facilitates the storage operation of the lubricating oil dripping inside the second box 2. The first one-way valve pipe 502 facilitates the transportation of the recycled lubricating oil into the fuel tank 501 for storage, providing convenience for the subsequent recycling of the lubricating oil. Each displacement of the linkage piston rod 509 can transport the oil or air collected in the collection box 503 into the fuel tank 501, increasing the pressure in the fuel tank 501. Then, the lubricating oil in the fuel tank 501 is transported through the connecting pipe 510 to the high-density brush roller 504 to quantitatively transport the oil to the multiple locking levers 401;

[0050] As Figure 1 、 Figure 2 、 Figure 3 shown, by manually rotating the locking member 8, one end of the locking member 8 can extend into the sliding sleeve seat 7, achieving the function of locking the moving positions of the first box 1 and the second box 2, avoiding the first box 1 and the second box 2 falling off their installation positions due to external impacts, and ensuring the stable installation effect of the first box 1 and the second box 2.

[0051] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
