Description

Technical Field

[0001] This invention belongs to the field of devices for fastening or fixing components or machine parts, and particularly relates to a locking device and a modular storage unit. Background Technology

[0002] In the field of automated warehousing, traditional container storage, stacking, and securing operations require human intervention to release or complete the securing process, resulting in low automation and severely restricting the efficiency of logistics transfer and handling. Furthermore, in space-constrained environments such as maritime logistics, the presence of human operators necessitates designated work areas and passageways, hindering the improvement of storage density. Therefore, it is necessary to install a locking device on containerized storage units (i.e., a work unit that neatly gathers packaged or unpackaged goods using various methods and equipment into a convenient loading, unloading, and handling unit, maintaining a certain form throughout the logistics process). This would eliminate the need for human intervention in the securing process, thereby improving storage density and work efficiency.

[0003] Chinese utility model patent CN 214837664 U, with an authorization announcement date of November 23, 2021, discloses a pneumatic conical locking device, comprising a body (i.e., housing) and steel balls (i.e., locking balls). The body has a hollow chamber penetrating through it. At both ends of the body are a cover plate and a plug sealing the hollow chamber, respectively. The plug has an air inlet for communication with an air compressor, meaning one end of the hollow chamber is connected to the outside. The body contains a conical core (i.e., locking pin), located within the hollow chamber; the conical surface of the core forms a receiving groove on the locking pin. The conical core and the inner surface of the hollow chamber... The walls are slidably sealed together by a sealing ring. The end of the cone core near the cover plate has a tapered surface. The side wall of the body near the cover plate has two through holes (i.e., side wall through holes). The through holes are perpendicular to the extension direction of the hollow cavity. The steel ball is located in the through hole and one end is in contact with the cone core. During the sliding stroke of the cone core, there is a locking position for the steel ball to protrude from the body to achieve locking and an unlocking position for the steel ball to retract into the body. An elastic element is also provided between the cone core and the body. The elastic element can deform when the cone core moves to the locking position to provide power for the cone core to return to the unlocking position.

[0004] During use, compressed air is introduced through the air inlet, the cone moves towards the cover plate, and the steel ball gradually retracts into the body, thus unlocking. To relock, simply adjust the output pressure of the air compressor; under the elastic force of the elastic element, the pneumatic cone-type locking device relocks. This locking device has high airtightness requirements. After adapting it to containerized storage units, regular maintenance is necessary, checking the airtightness of each device individually. If any locking device has an airtightness problem, the containerized storage unit will be unable to unlock from the floor or other containerized storage units. During later maintenance, it is impossible to determine the airtightness of the locking device visually; air must be pumped into the locking device to check its airtightness, making maintenance very inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a locking device and a containerized storage unit to solve the technical problem in the prior art that the locking device uses high-pressure gas for unlocking, which requires regular maintenance of the locking device, checking its airtightness one by one, and it is impossible to judge whether there is a problem with the airtightness of the locking device by visual inspection alone. Air must be pumped into the locking device to check the airtightness, which is very inconvenient for maintenance.

[0006] To achieve the above objectives, the technical solution of the locking device provided by the present invention is as follows:

[0007] A locking device includes a housing, a locking ball disposed in a through hole in the side wall of the housing, and a locking pin guided and movably mounted in the housing. The locking pin has a pressing surface and a receiving groove. During its movement stroke, the locking pin has a locking position where the pressing surface presses against the locking ball, causing the locking ball to partially protrude from the side wall of the housing. It also has an unlocking position where the locking ball is partially embedded in the receiving groove, causing the locking ball to retract into the through hole in the side wall. The locking device further includes a control rod guided and movably mounted on the housing and whose movement direction is perpendicular to the movement direction of the locking pin. The control rod has a pressing surface for pressing against the end of the locking pin, causing the locking pin to move to the unlocking position or the locking position. The control rod also has a relief groove that contacts the pressing surface and is used to avoid the end of the locking pin, causing the locking pin to move to the locking position or the unlocking position.

[0008] The beneficial effects are as follows: This invention is an improved invention. By setting a control lever, the locking and unlocking of the locking device can be achieved manually or through other power sources, solely by mechanical structure, without relying on an air compressor. When the control lever slides, it allows the top pressure surface or the clearance groove to contact the locking pin. Since the top pressure surface and the clearance groove are at different distances from the through hole along the direction extending along the hollow cavity, the relative position of the locking pin and the through hole can be adjusted, thereby placing the locking pin in the locked or unlocked position. During later maintenance of the locking device, it is not necessary to check the airtightness of the locking device; only visual inspection for obvious cracks or scratches is required, making maintenance convenient and saving maintenance time.

[0009] Furthermore, the clearance groove has a bottom wall and a side wall. When the locking pin is in the locked or unlocked position, the end of the locking pin contacts the bottom wall of the groove. At least one side wall of the groove is connected between the bottom wall and the pressing surface, and the bottom wall and the pressing surface are smoothly connected.

[0010] The beneficial effect is that by setting a transition surface, it is easier for the locking pin and the control lever to slide relative to each other.

[0011] Furthermore, the sidewall of the tank connecting the bottom wall and the top pressure surface is an arc surface.

[0012] The beneficial effects are: the curved surface structure is simple and has good guiding properties.

[0013] Furthermore, the locking device also includes an elastic element and a pulling element. The pulling element is connected to the control rod to pull the control rod to move. The two ends of the elastic element are in contact with the control rod and the housing, respectively. The elastic element can deform when the control rod controls the locking pin to move to the unlocked position, so as to provide power for the control rod to control the locking pin to return to the locked position.

[0014] The beneficial effects are: by setting a pull element, the movement of the control lever can be easily controlled, and by using an elastic element, the control lever can control the locking pin to return to the locked position.

[0015] Furthermore, the housing is provided with at least one end of a guide mounting cavity that communicates with the outside. The housing also includes an end plate located at the point where the guide mounting cavity communicates with the outside. The control rod is located in the guide mounting cavity. The end plate is provided with a through hole for the pulling member to pass through. The elastic member is a compression elastic member, which is located in the guide mounting cavity and between the control rod and the end plate.

[0016] The beneficial effects are: the guide mounting cavity facilitates the installation of the control rod; and the end plate facilitates the installation of the compression elastic element.

[0017] Furthermore, the pulling element is a rope.

[0018] The beneficial effects are: the pulling element is a rope, the structure is simple, and the direction can be changed by a fixed pulley, which facilitates the setting of the power source.

[0019] Furthermore, the control lever is equipped with an indicator that is integrated with the control lever so that it moves with the control lever. The housing is equipped with a corresponding mark to indicate the position of the locking pin.

[0020] The beneficial effect is that the indicator can easily determine the position of the locking pin, and thus determine the state of the locking device.

[0021] Furthermore, the indicator is an indicator pin, and the housing has an elongated hole through which the indicator pin passes, with the marking set at the corresponding position on the housing and the elongated hole.

[0022] The beneficial effect is that by setting an elongated hole, the position of the indicator pin can be directly observed from one side of the housing, which makes it easier to determine the position of the locking pin.

[0023] Furthermore, the housing includes a first housing and a second housing, with a side wall through hole provided on the second housing, a locking pin being guided and movably mounted on the second housing, and a control rod being guided and movably mounted on the first housing.

[0024] The beneficial effect is that the separate casing facilitates processing and manufacturing.

[0025] To achieve the above objectives, the technical solution of the containerized storage unit provided by the present invention is as follows:

[0026] A containerized storage unit includes a containerized storage unit body.

The locking pin has a pressing surface and a receiving groove. During the movement stroke of the locking pin, there is a locking position where the pressing surface presses against the locking ball, thereby causing the locking ball to partially protrude from the side wall of the housing. It also has an unlocking position where the locking ball is partially embedded in the receiving groove, thereby causing the locking ball to retract into the through hole in the side wall. The locking device also includes a control rod that is guided and movably installed on the housing and whose movement direction is perpendicular to the movement direction of the locking pin.

The control rod also has a relief groove that is in contact with the pressing surface and is used to avoid the end of the locking pin, thereby causing the locking pin to move to the locking position or the unlocking position.

[0027] The beneficial effects are as follows: This invention is an improved invention. By setting a control lever, the locking and unlocking of the locking device can be achieved through a power source and the control lever, thus eliminating the need for a passage for personnel operation and increasing storage density. When the control lever slides, it allows the top pressure surface or the clearance groove to contact the locking pin. Since the top pressure surface and the clearance groove are at different distances from the through hole along the direction extending along the hollow cavity, the relative position of the locking pin and the through hole can be adjusted, thereby placing the locking pin in the locked or unlocked position. During later maintenance of the locking device, it is not necessary to check the airtightness of the locking device; only visual inspection for obvious cracks or scratches is required, making maintenance convenient and saving maintenance time.

[0028] Furthermore, the clearance groove has a bottom wall and a side wall.

The elastic element can deform when the control rod controls the locking pin to move to the unlocked position, so as to provide power for the control rod to control the locking pin to return to the locked position.

[0033] The beneficial effects are: by setting a pull element, the movement of the control lever can be easily controlled, and by using an elastic element, the control lever can control the locking pin to return to the locked position.

[0034] Furthermore, the housing is provided with at least one end of a guide mounting cavity that communicates with the outside.

[0054] The present invention will be further described in detail below with reference to the embodiments.

[0055] Specific embodiment 1 of the containerized storage unit provided by the present invention:

[0056] The purpose of this embodiment is to provide a containerized storage unit that is convenient for later maintenance. By setting a power source and a control lever, the locking and unlocking of the locking device can be easily realized. During later maintenance, it is not necessary to check the airtightness of the locking device. It is only necessary to visually inspect whether there are cracks or obvious scratches on the locking device. Maintenance is convenient, quick and saves time.

[0057] like Figure 1-2 As shown in Figures 4-7, this embodiment specifically discloses a containerized storage unit, including a containerized storage unit body 2. The containerized storage unit body 2 is provided with at least one locking device 1 and a power source for controlling the locking device 1. The locking device 1 includes a housing, a locking ball 15 disposed in a through hole in the side wall of the housing, and a locking pin 12 guided and movably installed in the housing. The locking pin has a pressing surface and a receiving groove. During the movement stroke of the locking pin, there is a locking position where the pressing surface presses against the locking ball, thereby causing the locking ball to partially protrude from the side wall of the housing. It also has an unlocking position where the locking ball 15 is partially embedded in the receiving groove, so that the locking ball retracts into the through hole in the side wall. The locking device 1 also includes a control rod 6 guided and movably installed on the housing and whose movement direction is perpendicular to the movement direction of the locking pin. The control rod 6 has a pressing surface for pressing against the end of the locking pin to move the locking pin to the unlocking position or the locking position. The control rod 6 also has a relief groove that is in contact with the pressing surface and is used to avoid the end of the locking pin to move the locking pin to the locking position or the unlocking position. Specifically, in this embodiment, the housing has a hollow cavity with one end communicating with the outside. The locking pin 12 is located in the hollow cavity and can slide along the extension direction of the hollow cavity. The side wall of the housing is also provided with at least one through hole (i.e., side wall through hole). The locking ball 15 is located in the through hole and contacts the locking pin 12. The control rod 6 and the power source constitute a control mechanism. The control rod 6 and the housing can slide together in a direction perpendicular to the hollow cavity. The power source is used to drive the control rod 6 to slide. One end of the control rod 6 extends into the hollow cavity. The end of the control rod 6 near the locking pin 12 along the extension direction of the hollow cavity stops and cooperates with the locking pin 12 in the extension direction of the hollow cavity. The top pressure surface and the clearance groove are provided on the end of the control rod 6 near the locking pin 12. The distance from the top pressure surface and the clearance groove to the through hole is different in the extension direction of the hollow cavity. The power source is arranged on the containerized storage unit body 2. The power source is the traction mechanism 3.

[0058] In this embodiment, the sliding stroke of the control lever 6 includes a locking position where the clearance groove contacts the locking pin 12 to lock the pin 12, and an unlocking position where the pressure surface contacts the locking pin 12 to unlock the pin 12. However, in other embodiments, by changing the position of the receiving groove on the locking pin, the sliding stroke of the control lever 6 can include an unlocking position where the clearance groove contacts the locking pin 12 to unlock the pin 12, and a locking position where the pressure surface contacts the locking pin 12 to lock the pin 12. In this embodiment, the locking device 1 is bolted to the containerized storage unit body 2, and there are four locking balls 15, evenly distributed on the outer circumferential surface of the housing. However, in other embodiments, the locking device 1 can also be welded to the containerized storage unit body 2, as long as the locking device 1 is stably connected to the containerized storage unit body 2. The number of locking balls 15 can also be one, two, three, or other numbers.

[0059] By setting up a control lever 6 and a power source, the locking and unlocking of the locking device 1 can be achieved solely through a mechanical structure without relying on an air compressor. The power source drives the control lever 6 to slide, allowing the pressure surface or clearance groove to contact the locking pin 12. Since the pressure surface and clearance groove are at different distances from the through hole along the direction extending from the hollow cavity, the relative position of the locking pin 12 and the through hole can be adjusted, thus placing the locking pin 12 in the locked or unlocked position. During later maintenance of the locking device 1, it is not necessary to check its airtightness; only a visual inspection is needed to determine if there are obvious cracks or scratches. This simplifies maintenance and saves time. Of course, in other embodiments, the power source can also be a cylinder. The main purpose of this invention is to provide a locking device that facilitates later maintenance; the cylinder can be maintained using existing maintenance methods.

[0060] To facilitate the connection of multiple containerized storage units together, in this embodiment, as follows: Figure 1 and 3As shown, the containerized storage unit body 2 is also provided with a locking base 4 for cooperating with the locking device 1. The locking base 4 has a cavity for the locking device 1 to extend into, and the cavity has a narrower section and a wider section. At the narrower section of the cavity, the locking base 4 cooperates with the stop bead in the locking device 1 to prevent the locking device 1 from falling off the locking base 4. The locking devices 1 are spaced apart on the upper surface and / or lower surface of the containerized storage unit body 2, and the surface of the containerized storage unit body 2 opposite to each locking device 1 is provided with a locking base 4 corresponding to the position of each locking device 1. By providing locking bases 4 or locking devices 1 on the upper and lower surfaces of the containerized storage unit body 2, multiple containerized storage units can be easily connected together. In this embodiment, four locking devices 1 are provided at the four corners of the lower surface of each containerized storage unit body 2, and four locking bases 4 are provided at positions corresponding to the locking devices 1 on the upper surface of the containerized storage unit body 2. At the same time, locking bases and locking devices are respectively provided at corresponding positions on the upper and lower surfaces, so that multiple containerized storage units can be connected by manufacturing only one type of containerized storage unit.

[0061] To facilitate the installation of the control lever 6 and the control of the locking pin 12 via the control lever 6, in this embodiment, as follows: Figure 6-7 As shown, the clearance groove has a bottom wall and a side wall. When the locking pin is in the locked or unlocked position, the end of the locking pin contacts the bottom wall of the groove. At least one side wall connects the bottom wall and the contact surface, allowing for a smooth transition between the bottom wall and the contact surface. Specifically, the side wall connecting the bottom wall and the contact surface is an arc surface. By providing a transition surface, relative sliding between the locking pin 12 and the control rod 6 can be facilitated.

[0062] In this embodiment, the housing is a split structure, comprising a first housing 5 and a second housing 17. A sidewall through-hole is provided on the second housing 17, a locking pin is movably mounted on the second housing 17, and a control rod 6 is movably mounted on the first housing 5. Specifically, the first housing 5 and the second housing 17 are connected as a single unit. The control rod 6 is slidably fitted to the first housing 5 along an extension direction perpendicular to the hollow cavity. The hollow cavity is located on and penetrates the second housing 17, or the hollow cavity is simultaneously located on the second housing 17 and the first housing 5 at corresponding positions and penetrates the second housing 17. The first housing 5 has a guide mounting cavity with one end communicating with the outside. The extension direction of the guide mounting cavity is perpendicular to the extension direction of the hollow cavity. The control rod 6 is slidably mounted within the guide mounting cavity, and both ends of the control rod 6 along the extension direction of the hollow cavity are engaged with stops on the first housing 5. However, in other embodiments, the housing can also be integrally formed, i.e., a single unit, with both the hollow cavity and the guide mounting cavity located within the housing. The separate housing design facilitates the machining of the hollow cavity and the guide mounting cavity, and also allows for the easy placement of the control rod 6 within the guide mounting cavity.

[0063] In this embodiment, as Figure 6 and 7 As shown, the first housing 5 and the second housing 17 are connected as a whole by connecting bolts 11. A baffle 13 is also fixedly connected to the second housing 17 by fixing bolts 14. The baffle 13 is located within the hollow cavity. A protrusion along the axial direction of the locking pin 12 is provided on the circumferential surface of the locking pin 12. The protrusion cooperates with the baffle 13 to limit the extreme position of the locking pin 12 moving away from the through hole. A compression spring 16 is also fitted on the outer circumferential surface of the locking pin 12. One end of the compression spring 16 contacts the end of the protrusion near the through hole, and the other end contacts the second housing 17. The compression spring 16 deforms when the locking pin 12 moves to the unlocked position, providing power for the locking pin 12 to return to the locked position. The locking pin 12 is also provided with a receiving groove for accommodating the locking ball 15. When the locking pin 12 is in the unlocked position, the locking ball 15 can enter the receiving groove to retract into the second housing 17. However, in other embodiments, the position of the receiving groove can be changed, for example, by changing... Figure 6 The position of the middle receiving slot is so that Figure 6 The locking pin 12 is in the unlocked position. This embodiment will... Figure 6 The advantage of setting the central locking pin 12 to the locked position is that when locked, the power source in the control mechanism does not need to continuously provide power; the power source only needs to control the movement of the control lever 6 when unlocking is desired.

[0064] To facilitate the control of the movement of the control lever 6, in this embodiment, the end of the control lever 6 near the power source is connected to the power source via a pulling member. The locking device also includes an elastic member and a pulling member. The two ends of the elastic member are in contact with the control lever 6 and the housing, respectively. The elastic member can deform when the control lever 6 controls the locking pin to move to the unlocking position, providing power for the control lever to control the locking pin to return to the locked position. That is, the elastic member can deform when the control lever 6 moves to the unlocking position, providing power for the control lever 6 to return to the locked position. By setting a pulling member, the movement of the control lever 6 can be easily controlled, and the elastic member can make the control lever 6 return to the locked position. In this embodiment, the pulling member is a steel cable 8, and the traction mechanism 3 is connected to the control lever 6 via the steel cable 8. However, in other embodiments, the pulling member can also be a nylon rope lock, etc. The advantage of setting the pulling member as a rope is that the structure is simple and the direction can be changed by a fixed pulley, thereby facilitating the setting of the power source.

[0065] To facilitate the installation of the elastic element, in this embodiment, the elastic element is a compression elastic element 7. The housing also includes an end plate 9 disposed at the junction of the guide mounting cavity and the outside. The control rod is disposed in the guide mounting cavity. The end plate 9 has a through hole for the pulling member to pass through. The compression elastic element is disposed in the guide mounting cavity and located between the end plate 9 and the control rod 6. The end plate 9 is fixed to the first housing 5 by fastening bolts 10. In this embodiment, the compression elastic element is a compression spring. The end plate 9 facilitates the installation of the compression elastic element 7, and the guide mounting cavity guides the compression elastic element 7.

[0066] To facilitate determining the status of the locking device 1, in this embodiment, the control lever 6 is equipped with an indicator. The indicator is integrated with the control lever 6 and moves with it. The housing has a corresponding mark to indicate the position of the control lever 6. In this embodiment, the indicator is an indicator pin 19, and the housing has an elongated hole through which the indicator pin 19 passes. The mark is located at a position on the housing corresponding to the elongated hole. However, in other embodiments, the indicator may be a colored mark on the control lever, etc. The indicator allows for easy determination of the position of the control lever 6, thereby determining the status of the locking device 1.

[0067] When using it, first install the containerized storage unit located at the bottom layer, such as... Figure 8 In the marine floor shown, in this embodiment, the marine floor is fixed to the ground and includes locking bases 4. The locking bases 4 are arranged in a matrix to connect each locking device 1 on the containerized storage unit to the locking bases 4. Filling material 18 for supporting the containerized storage unit is provided between the locking bases 4. However, in other embodiments, locking devices 1 can also be provided on the marine floor, or locking devices 1 and locking bases 4 can be provided at the same time (that is, corresponding to the lower surface of the containerized storage unit body, locking devices and locking bases can be provided separately on the lower surface of the containerized storage unit body, or locking devices and locking bases can be provided at the same time, and locking bases or locking devices corresponding to locking devices or locking bases can be provided on the upper surface of the containerized storage unit body). During the docking of containerized storage units or the installation of the lowest-level containerized storage unit on the ship's floor, the traction mechanism 3 first controls the steel cable 8 to pull the control rod 6. The top surface of the control rod 6 engages with the locking pin 12 to put the locking pin 12 in the unlocked position, and the locking device 1 is inserted into the locking base 4. Then, the traction mechanism 3 is controlled to move the control rod 6 in the opposite direction, and the clearance groove of the control rod 6 engages with the locking pin 12 to put the locking pin 12 in the locked position. Since no manual operation is required, there is no need to leave operating areas such as personnel access passages, which can significantly increase the effective storage space and is conducive to improving storage density and the degree of automation of operations.

[0068] Specific embodiment 2 of the containerized storage unit provided by the present invention:

[0069] The purpose of this embodiment is to provide a different containerized storage unit. The main difference between this embodiment and specific embodiment 1 is that in this embodiment, four locking devices are provided on the lower surface of only one type of containerized storage unit, and four locking devices are provided on its upper surface. This embodiment also includes another type of containerized storage unit, which has four locking bases on both its upper and lower surfaces. In use, the two different containerized storage units need to be used alternately.

[0070] Specific embodiment 3 of the containerized storage unit provided by the present invention:

[0071] The purpose of this embodiment is to provide a different control lever. The main difference between this embodiment and specific embodiment 1 is that in this embodiment, the control lever does not include a transition surface, and the side of the locking pin that contacts the control lever is a spherical surface, thereby realizing the relative movement between the locking pin and the control lever.

[0072] Specific embodiment 4 of the containerized storage unit provided by the present invention:

[0073] The purpose of this embodiment is to provide a different transition surface. The main difference between this embodiment and specific embodiment 1 is that in this embodiment, the transition surface is a multi-step surface. Of course, it can also be a curved surface with a gradually increasing radius from the bottom wall of the groove to the top pressure surface.

[0074] Specific embodiment 5 of the containerized storage unit provided by the present invention:

[0075] The purpose of this embodiment is to provide a different transmission method and a different pulling component.
