Description

Technical Field

[0001] The present case involves a latch structure, and more particularly, a casing latch structure for a cabinet, which is suitable for fixing a power supply unit in a power cabinet. The design can reduce material costs, improve assembly difficulties, and reduce the risk of breaking components during installation of the latch structure. Background Art

[0002] Power supply unit (PSU) products are often integrated into power cabinets and fixed by latch structures. However, the latch structures used to fix PSUs to power cabinets are relatively small, making manual assembly very difficult, and they must be assembled and operated with a plastic front cover, so costs cannot be reduced. In addition, when the PSU is installed in the power cabinet, if the latch structure is not completely retracted into the front cover, the latch structure components may be broken during the insertion of the PSU into the power cabinet.

[0003] On the other hand, the traditional latch structure is only operated by turning, and the original components of the latch structure may be loosened due to backlash after multiple turnings, and it cannot be ensured that the latch structure can be accurately positioned at the specified position of the power cabinet.

[0004] In view of this, it is necessary to provide a casing latch structure suitable for fixing the power supply unit in the power cabinet. The material cost can be reduced through design, and the difficulty of assembly can be improved, thereby reducing the risk of breaking the abutment when the latch structure is installed, so as to solve the deficiencies of the prior art. Summary of the invention

[0005] The purpose of this case is to provide a casing latch structure suitable for fixing a power supply unit in a power cabinet. The design can reduce material costs, improve assembly difficulties, and reduce the risk of breaking a stop member when the latch structure is installed.

[0006] Another object of the present invention is to provide a housing latch structure suitable for fixing a power supply unit in a power cabinet. The L-shaped top member is arranged on the body by a package injection process, presenting an integrated design, which simplifies the assembly process of the housing latch structure. The body of the housing latch structure can be adjusted to control the tightness through a thread, and is directly fixed to a specific position of the metal shell by a clamping method, which helps to solve the problems of backlash and looseness caused by vibration or multiple toggling of the latch structure after the traditional power supply unit is fixed to the power cabinet. In addition, since the body of the housing latch structure can be directly fixed on the metal shell, the complex assembly of the plastic front cover can be omitted, and the overall structural strength is improved. Among them, the components of the housing latch structure are clamped at a specific position of the metal shell by a thread adjustment mechanism, which further simplifies the assembly requirements and improves the assembly difficulty of the traditional latch structure. Furthermore, the metal shell of the housing latch structure is easy to be constructed on power supply units of different sizes and specifications, and the design is flexible. Even under the condition of limited structural space, the housing latch structure can be directly integrated into the metal shell on the power supply unit, without the need to increase the cost of the plastic front cover, etc., reducing material costs and improving assembly difficulties. On the other hand, the operation of fixing the power supply unit to the power cabinet is achieved by the displacement of the main body on the casing latch structure corresponding to the metal shell. An automatic rebound function can be increased by setting a spring between the main body and the metal shell, or a stop protrusion of the sliding groove can be set to ensure that the position of the support piece is positioned relative to the metal shell, thereby reducing the risk of the support piece being broken when the casing latch structure installs the power supply unit to the power cabinet.

[0007] In order to achieve the above-mentioned purpose, the present case provides a casing latch structure, including a shell, a main body, a clamping member, a locking member and a push member.

The sliding part is connected between the clamping part and the locking part, and is accommodated in the sliding groove. The clamping part and the locking part are respectively located on two opposite sides of the second wall. The clamping member is sleeved between the sliding part and the locking part. The locking member is engaged with the locking part to lock the clamping member to allow the clamping member to push against the second wall and fix the position of the sliding part relative to the sliding groove, or release the clamping member to allow the sliding part to slide relative to the sliding groove. The push-up member includes a push-up top and an embedded portion, wherein the push-up top is spatially opposite to the through hole on the first wall, the embedded portion is connected to the push-up top and spatially opposite to the sliding groove on the second wall, wherein when the sliding portion approaches the first wall along the sliding groove, the front end of the push-up top passes through the first wall through the through hole; wherein when the sliding portion moves away from the first wall along the sliding groove, the push-up top does not protrude outside the first wall.

[0010] In one embodiment, the locking portion of the main body and the locking member are respectively a screw thread and a nut, which are correspondingly engaged with each other, wherein when the locking member pushes against the clamping member to press the second wall, the main body is fixed to the shell through the clamping portion and the clamping member, wherein when the locking member is detached from the second wall and the clamping member is released, the sliding portion is allowed to slide relative to the sliding groove.

[0011] In one embodiment, the main body further includes a mounting plane disposed between the sliding portion and the locking portion, and recessed relative to the sliding portion and the locking portion, wherein the clamping member is a buckle fixed between the sliding portion and the locking portion through the mounting plane.

[0012] In one embodiment, the sliding groove penetrates the second wall, extends along the first direction, and includes a first position and a second position respectively located at two opposite ends, and the sliding part is allowed to slide between the first position and the second position; when the sliding part moves to the first position, the abutting top part penetrates the first wall through the through hole; when the sliding part moves to the second position, the abutting top part is accommodated in the shell.

[0013] In one embodiment, the housing latch structure further includes an elastic member disposed between the body and the first wall, wherein when the locking member releases the clamping member to allow the sliding portion to slide relative to the sliding groove, the elastic member drives the body away from the first wall to move the sliding portion to the second position.

[0014] In one embodiment, the elastic member is a compression spring, which is sleeved on the outer periphery of the top portion to provide an elastic restoring force between the body and the first wall.

Figure 6A schematic diagram showing the sliding portion of the main body in the housing latch structure of the first preferred embodiment of the present invention moving to the second position of the sliding groove. Figures 1 to 6 . In order to achieve an application such as fixing a power supply unit in a power cabinet, the present case provides a housing latch structure 1 including a housing 10, a body 20, a clamp 30, a locking member 40 and a push member 50. The housing 10 is, for example, a metal shell of a power supply unit, and includes a first wall 11, a second wall 12, a through hole 13 and a sliding groove 14. In this embodiment, the first wall 11 is, for example, a left wall or a right wall, connected to the second wall 12 such as a front wall, the first wall 11 and the second wall 12 are perpendicular to each other, the through hole 13 is set through the first wall 11, and the sliding groove 14 is set through the second wall 12.

[0061] It should be noted that the housing latch structure 1 may include an implementation method in which the left side wall or / and the right side wall are implemented as the first wall 11. The following description only uses the left side wall as the first wall 11 for description, which is not limited to this case. In this embodiment, the body 20 is disposed in the internal space 100 of the shell 10, spatially opposite to the first wall 11 and the second wall 12, and includes a clamping portion 21, a sliding portion 22 and a locking portion 23. The sliding portion 22 is connected between the clamping portion 21 and the locking portion 23, and is accommodated in the sliding groove 14 of the shell 10. The clamping portion 21 and the locking portion 23 are respectively located on two opposite sides of the second wall 12. That is, the clamping portion 21 is located on the inner side of the second wall 12, and the locking portion 23 is located on the outer side of the second wall 12. In this embodiment, the clamping member 30 is, for example, an E-shaped buckle, which is sleeved between the sliding portion 22 and the locking portion 23. The locking member 40 is engaged with the locking portion 23 of the body 20 to lock the clamp member 30 to allow the clamp member 30 to abut the second wall 12 and fix the position of the sliding portion 22 relative to the sliding groove 14, or release the clamp member 30 to allow the sliding portion 22 to slide relative to the sliding groove 14. The abutting member 50 includes an abutting top portion 51 and an embedded portion 52. The abutting top portion 51 is spatially opposite to the through hole 13 on the first wall 11. The embedded portion 52 is connected to the abutting top portion 51 and is spatially opposite to the sliding groove 14 on the second wall 12. When the sliding portion 22 is allowed to slide relative to the sliding groove 14 and the sliding portion 22 approaches the first wall 11 along the sliding groove 14, the front end of the abutting top portion 51 passes through the first wall 11 through the through hole 13. Alternatively, when the sliding portion 22 is allowed to slide relative to the sliding groove 14 and the sliding portion 22 moves away from the first wall 11 along the sliding groove 14, the abutting top portion 51 does not protrude outside the first wall 11.

[0062] In this embodiment, the push-up member 50 is a metal member, and the push-up portion 51 and the embedded portion 52 are connected to each other to form, for example, an L-shaped rod. The body 20 is, for example, made of plastic, and the embedded portion 52 of the push-up member 50 can be embedded in the body 20 by, for example, an injection molding process, and the body 20 simultaneously forms the clamping portion 21, the sliding portion 22, and the locking portion 23. The L-shaped push-up member 50 is disposed on the body 20 by an injection molding process, and is an integrated design, which can simplify the assembly process of the housing latch structure 1. In this embodiment, a step structure is formed between the clamping portion 21 and the sliding portion 22, which facilitates the assembly of the body 20 and the housing 10. When the integrated push-up member 50 and the body 20 are to be assembled to the housing 10, the locking portion 23 of the body 20 passes through the sliding groove 14 on the second wall 12 from the internal space 100, so that the sliding portion 22 is accommodated in the sliding groove 14. In this embodiment, the embedded portion 52 of the abutting member 50 passes through the clamping portion 21 , the sliding portion 22 and at least a portion of the locking portion 23 of the body 20 , which helps to increase the structural strength.

[0063] In this embodiment, the first wall 11 of the metal shell 10 further includes a folding surface 15 connected to the second wall 12, and the folding surface 15 has a guide groove 16. The guide groove 16 has an opening facing the direction away from the second wall 12 (opposite to the Y-axis direction), and the other end of the guide groove 16 is aligned with the through hole 13. Therefore, the folding surface 15 and the guide groove 16 further constitute a mechanism for the push-up member 50 to align with the through hole 13. When the integrated push-up member 50 and the body 20 are assembled to the shell 10 along the Y-axis direction, the locking portion 23 of the body 20 passes through the sliding groove 14 on the second wall 12 from the internal space 100, and the front end of the push-up portion 51 can slide along the guide groove 16, so that the sliding portion 22 is accommodated in the sliding groove 14, and the front end of the push-up portion 51 moves to the end of the guide groove 16 and is aligned with the through hole 13, thereby simplifying the assembly process. Of course, the assembly method of the case latch structure 1 of this case is not limited to this.

[0064] In this embodiment, the clamp 30 is, for example, a buckle. After the locking portion 23 of the body 20 passes through the sliding groove 14 on the second wall 12 from the internal space 100 along the Y-axis direction, the clamp 30 is sleeved between the sliding portion 22 and the locking portion 23, so that the sliding portion 22 can be restricted to slide in the sliding groove 14. In this embodiment, the body 20 further includes a mounting plane 24, which is disposed between the sliding portion 22 and the locking portion 23, and is recessed relative to the sliding portion 22 and the locking portion 23. If the clamp 30 is an E-shaped buckle, it can be easily fixed between the sliding portion 22 and the locking portion 23 through the mounting plane 24. The setting of the mounting plane 24 helps to optimize the assembly of the E-shaped buckle. Of course, the present case is not limited thereto.

[0065] In this embodiment, the locking portion 23 of the body 20 and the locking member 40 are respectively a screw thread and a nut, which mesh with each other. When the locking member 40 pushes the clamping member 30 against the second wall 12, the body 20 is fixed to the housing 10 through the clamping portion 21 and the clamping member 30. In addition, when the locking member 40 is separated from the second wall 12 and the clamping member 30 is released, the sliding portion 22 is allowed to slide relative to the sliding groove 14.

[0066] It is worth noting that the body 20 of the housing latch structure 1 can adjust the tightness of the clamping member 30 and the housing 10 through the degree of threaded engagement between the locking portion 23 and the locking member 40, and is directly fixed to a specific position of the metal housing 10 by clamping, which helps to solve the problems of backlash and looseness caused by vibration or multiple activation of the housing latch structure 1 after the traditional power supply unit is fixed to the power cabinet. In addition, since the body 20 of the housing latch structure 1 can be directly fixed to the metal housing 10, the complex assembly of the traditional plastic front cover can be omitted, while the overall structural strength is improved. The body 20, the clamping member 30 and the locking member 40 of the housing latch structure 1 are clamped at a specific position of the housing 10 through a threaded adjustment mechanism, which simplifies the assembly requirements and improves the difficulty of assembling the traditional latch structure.

[0067] In this embodiment, the sliding groove 14 is, for example, an elongated through hole that penetrates the second wall 12, extends along a first direction parallel to the X-axis, and includes a first position and a second position located at two opposite ends. When the locking member 40 is detached from the second wall 12 and the clamping member 30 is released, the sliding portion 22 is allowed to slide between the two opposite ends (i.e., between the first position and the second position). In this embodiment, when the sliding portion 22 is allowed to slide relative to the sliding groove 14, and the sliding portion 22 approaches the first wall 11 along the sliding groove 14 to the first position (e.g., Figure 5 As shown in FIG. 1 , the top portion 51 passes through the through hole 13 and penetrates the first wall 11. Then, the user operates the locking member 40 to push the clamping member 30 against the second wall 12, so that the body 20 is fixed to the housing 10 through the clamping portion 21 and the clamping member 30, and the sliding portion 22 is locked in the first position of the sliding groove 14, as shown in FIG. Figure 5 In this embodiment, when the sliding portion 22 is allowed to slide relative to the sliding groove 14, and the sliding portion 22 moves away from the first wall 11 along the sliding groove 14 to the second position (such as Figure 6 As shown in FIG. 1 , the abutting top portion 51 does not protrude out of the first wall 11 , and the abutting member 50 is completely accommodated in the internal space 100 of the housing 10 .

[0068] Figure 7 A schematic diagram showing a first preferred embodiment of the present invention wherein the housing latch structure is fixedly installed to a cabinet is disclosed. Figure 8 A schematic diagram showing the first preferred embodiment of the present invention, wherein the housing latch structure allows movement relative to the cabinet. Figures 1 to 8In this embodiment, the housing latch structure 1 is suitable for fixing the power supply unit in the power cabinet 9. The power supply unit is, for example, structured on the housing 10. When the metal housing 10 of the housing latch structure 1 is inserted into the power cabinet 9, the user can use the exposed locking portion 23 to slide the sliding portion 22 relative to the sliding groove 14 to the first position, so that the top portion 51 passes through the through hole 13 through the first wall 11 and engages with the positioning hole 90 of the power cabinet 9. Thereafter, the user operates the locking member 40 to push the clamping member 30 against the second wall 12, so that the body 20 can be fixed to the housing 10 through the clamping portion 21 and the clamping member 30, and the sliding portion 22 is locked in the first position of the sliding groove 14 (see Figure 5 ), so that the housing 10 containing the power supply unit is stably fixed in the power cabinet 9, such as Figure 7 In addition, the user can also release the clamping member 30 through the exposed locking member 40, and slide the sliding portion 22 relative to the sliding groove 14 to the second position. Afterwards, the user operates the locking member 40 to push the clamping member 30 against the second wall 12, so that the sliding portion 22 of the body 20 is locked in the second position of the sliding groove 14 (see Figure 6 ). At this time, the top portion 51 does not protrude out of the first wall 11, and the push-up member 50 is completely contained in the internal space 100 of the shell 10, so that the shell 10 containing the power supply unit can be moved relative to the power supply cabinet 9 to complete disassembly or maintenance. Since the metal shell 10 of the housing latch structure 1 is easily constructed on power supply units of different sizes, the design is flexible. Even under the condition of limited structural space, the housing latch structure 1 can be directly integrated into the metal shell 10 of the power supply unit, and there is no need to increase the cost of the plastic front cover, etc., which can reduce the material cost and improve the difficulty of assembly. On the other hand, the operation of fixing the power supply unit to the power supply cabinet 9 is achieved by the displacement of the main body 20 on the housing latch structure 1 corresponding to the housing 10, and the locking is carried out by cooperating with the threaded adjustment mechanism of the main body 20, the clamping member 30 and the locking member 40, which helps to ensure that the position of the push-up member 50 relative to the shell 10 is in a fixed position, and reduces the risk of the push-up member 50 being broken when the housing latch structure 1 installs the power supply unit to the power supply cabinet 9.

Fig.10 A structural diagram of components of a detachable housing in a housing latch structure according to a second preferred embodiment of the present invention is disclosed. Fig.11 The following is an exploded view of the components of the housing latch structure of the second preferred embodiment of the present invention. In this embodiment, the housing latch structure 1a and Figures 1 to 8 The housing latch structure 1 shown is similar, and the same element numbers represent the same elements, structures and functions. Figures 1 to 11. In this embodiment, the housing latch structure 1a also includes an elastic member 60, which is disposed between the body 20 and the first wall 11 to provide an elastic restoring force between the body 20 and the first wall 11. In this embodiment, the first wall 11 of the metal shell 10 also includes a folding surface 15 connected to the second wall 12, and the folding surface 15 has a guide groove 16, the guide groove 16 opens in a direction away from the second wall 12 (opposite to the Y-axis direction), and the end of the guide groove 16 is aligned with the through hole 13. Therefore, the folding surface 15 and the guide groove 16 further constitute a mechanism for the push member 50 to align with the through hole 13, and when the body 20 is assembled to the shell 10, the elastic member 60 is always pressed between the first wall 11 and the body 20. Of course, the present case is not limited to this.

[0070] In this embodiment, when the locking member 40 releases the clamping member 30 to allow the sliding portion 22 to slide relative to the sliding groove 14, the elastic restoring force provided by the elastic member 60 will drive the main body 20 away from the first wall 11, so that the sliding portion 22 moves to the second position, ensuring that the push member 50 is completely accommodated in the internal space 100 of the shell 10. When the user wants to fix the shell 10 containing the power supply unit in the power cabinet 9, the elastic restoring force of the elastic member 60 can be overcome by the exposed locking member 40, and the sliding portion 22 can be moved to slide relative to the sliding groove 14 to the first position. Thereafter, the user operates the locking member 40 to push the clamping member 30 against the second wall 12, so that the main body 20 can be fixed to the shell 10 through the clamping portion 21 and the clamping member 30, and the sliding portion 22 is locked in the first position of the sliding groove 14 (see Figure 5 ), so that the housing 10 containing the power supply unit is stably fixed in the power cabinet 9 (see Figure 7 In this embodiment, the elastic member 60 is, for example, a compression spring, which is sleeved on the outer periphery of the abutting top portion 51 to provide elastic restoring force between the body 20 and the first wall 11. Of course, the present invention is not limited thereto.

[0071] As can be seen from the above, the operation of fixing the shell 10 containing the power supply unit to the power cabinet 9 can be achieved by the displacement of the main body 20 on the casing latch structure 1a corresponding to the shell 10, and the automatic rebound function can be increased between the main body 20 and the shell 10 by setting an elastic member 60 such as a spring to ensure that the position of the push piece 50 relative to the shell 10 is positioned, thereby reducing the risk of the push piece 50 being broken when the casing latch structure 1a installs the power supply unit to the power cabinet 9.

Fig.13 The schematic diagram of the housing structure of the third preferred embodiment of the present invention discloses the housing latch structure. In this embodiment, the housing latch structure 1b and Figures 1 to 11 The housing latch structures 1 and 1a shown are similar, and the same element numbers represent the same elements, structures and functions. Figures 1 to 13 . In this embodiment, the housing 10a of the housing latch structure 1b can be changed in design to accommodate power supply units of different sizes, and the slide groove 14 also includes a stop convex portion 17, which is disposed between two opposite ends of the slide groove 14, that is, between the first position and the second position. The design of the stop convex portion 17 further increases the user's feel for moving and positioning the sliding portion 22 through the locking member 40 or the locking portion 23, ensuring that the position of the push member 50 relative to the housing 10 is in place, thereby reducing the risk of breaking the push member 50 when the housing latch structure 1b is used to install the power supply unit to the power cabinet 9. Of course, the present case is not limited to this and will not be described in detail.

[0073] In summary, the present invention provides a casing latch structure suitable for fixing a power supply unit in a power cabinet. The design can reduce material costs, improve assembly difficulties, and reduce the risk of breaking the abutment when the latch structure is installed. The L-shaped abutment is set on the body by a package injection process, presenting an integrated design, which simplifies the assembly process of the casing latch structure. The body of the casing latch structure can be adjusted to control the tightness through threads, and is directly fixed to a specific position of the metal shell by clamping, which helps to solve the problems of backlash and looseness caused by vibration or multiple toggling of the latch structure after the traditional power supply unit is fixed to the power cabinet. In addition, since the body of the casing latch structure can be directly fixed on the metal shell, the complex assembly of the plastic front cover can be omitted, and the overall structural strength is improved. The components of the casing latch structure are clamped at specific positions of the metal shell through a thread adjustment mechanism, which further simplifies the assembly requirements and improves the assembly difficulties of the traditional latch structure. Furthermore, the metal shell of the casing latch structure is easy to be constructed on power supply units of different sizes and specifications, and the design is flexible. Even under the condition of limited structural space, the housing latch structure can be directly integrated into the metal shell on the power supply unit, without the need to add the cost of the plastic front cover, etc., reducing the material cost and improving the difficulty of assembly. On the other hand, the operation of fixing the power supply unit to the power cabinet is realized by the displacement of the body on the housing latch structure corresponding to the metal shell. The body and the metal shell can be provided with a spring to increase the automatic rebound function, or a stop convex portion of the sliding groove can be provided to ensure that the position of the abutment relative to the metal shell is in position, reducing the risk of the housing latch structure breaking the abutment when the power supply unit is installed to the power cabinet.
