Description

Technical Field

[0001] This utility model relates to the field of KVM all-in-one machine technology, and in particular to a KVM all-in-one machine locking structure and a KVM all-in-one machine. Background Technology

[0002] Multi-device switchers (KVM all-in-one machines) integrate LED displays, keyboards, and touchpads, solving the problem of large space occupation by spatial electronic devices. However, current KVM all-in-one machines suffer from unreliable locking mechanisms and inconvenient operation. For example, Chinese patent CN108008835B discloses a reinforced KVM switch mounting structure, which has a locking mechanism at one end of the display. The locking tongue of the locking mechanism can engage with a limiting hole on the side of the base under the elastic force of a spring, achieving a closed and locked fit between the display and the base. However, this mounting structure only has a locking mechanism at one end of the display, resulting in an insufficiently tight fit between the display and the base, making relative movement easy and failing to meet military vibration requirements. Moreover, when opening and closing the display, the operating lever must be continuously pushed to retract the locking tongue into the display and release the lock between the display and the base. During this time, the operator's hand must constantly push the operating lever, preventing other actions and making operation inconvenient. Therefore, there is an urgent need for a KVM all-in-one machine locking structure and a KVM all-in-one machine that improves reliability, reduces vibration, and is more convenient to operate. Utility Model Content

[0003] The purpose of this invention is to provide a locking structure for a KVM switch and a KVM switch, so as to solve the problems existing in the prior art, improve reliability, reduce vibration, and make operation more convenient.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a locking structure for a KVM all-in-one machine, including: a panel, a housing, a first locking structure, and a second locking structure. The panel is rotatably connected to the housing. The first locking structure and the second locking structure are respectively disposed at both ends of the panel. Both the first locking structure and the second locking structure include a knob and a limiting pin. Two knobs are rotatably connected to the panel. The limiting pin is disposed inside the panel. The housing has two holes, and the positions of the two holes correspond to the positions of the two limiting pins. The knob has at least a first state and a second state. When the panel is closed on the housing and the knob is in the first state and held, the limiting pin can extend into the hole. When the knob is rotated to the second state and held, the limiting pin can be pulled out of the hole, and the panel can rotate and unfold relative to the housing.

[0006] In some embodiments, both the first locking structure and the second locking structure further include a limiting member and an elastic member. The panel has a receiving cavity, and the limiting pin, the limiting member, and the elastic member are all disposed within the receiving cavity. The limiting pin has a pin shaft limiting surface, and the receiving cavity has an inner cavity limiting surface. The pin shaft limiting surface and the inner cavity limiting surface are arranged opposite to each other. The two ends of the elastic member respectively abut against the pin shaft limiting surface and the inner cavity limiting surface. A through hole is provided on one side of the receiving cavity, and the through hole corresponds to the position of the hole. The knob is rotatably connected to the panel around a first rotating shaft, which is perpendicular to the axis of the limiting pin. One end of the knob extends into the receiving cavity and is fixedly connected to the limiting member. The limiting member has a first position and a second position. The first position is farther away from the knob than the second position. The end of the limiting pin that is farther away from the through hole is the first end. The knob can rotate and drive the limiting member to rotate. When the knob is rotated to the first state, the first position contacts the first end, and the limiting pin can be pushed out of the through hole by the first position and inserted into the hole. When the knob is rotated to the second state, the limiting pin can be pulled out of the hole and retracted into the receiving cavity under the rebound action of the elastic member, and the second position can contact the first end.

[0007] In some embodiments, the limiting member includes a first portion, the first portion having a partially elliptical cross-section perpendicular to the first axis of rotation, the vertex of the first portion on the major axis of the ellipse forming the first position, the vertex of the first portion on the minor axis of the ellipse forming the second position, the limiting member being fixedly connected to the knob, and the first axis of rotation passing through the center point of the first portion.

[0008] In some embodiments, the limiting member further has a first limiting surface and a second limiting surface, and the receiving cavity further has a third limiting surface and a fourth limiting surface. The first limiting surface, the second limiting surface, the third limiting surface, and the fourth limiting surface are all parallel to the first rotating shaft. The first limiting surface is parallel to the second limiting surface, and the third limiting surface is perpendicular to the fourth limiting surface. When the knob is rotated to the first state, the first limiting surface can contact the third limiting surface. When the knob is rotated to the second state, the second limiting surface can contact the fourth limiting surface.

[0009] In some embodiments, both the first locking structure and the second locking structure further include a locking sleeve. The panel is provided with a mounting hole communicating with the receiving cavity and the outside. The locking sleeve is fixedly connected in the mounting hole and forms an interference fit with the mounting hole. The locking sleeve is provided with a insertion hole. The knob passes through the insertion hole and extends into the receiving cavity. The inner side of the insertion hole fits against the outer side of the knob.

[0010] In some embodiments, the locking sleeve and the mounting hole form an interference fit.

[0011] In some embodiments, the knob has a plug portion with a rectangular cross-section perpendicular to the first rotating axis, and the limiting member has a plug hole with a rectangular hole, into which the plug portion can be inserted.

[0012] In some embodiments, the elastic element is a spring.

[0013] In some embodiments, both the first locking structure and the second locking structure further include a guide block, which is fixedly connected to the receiving cavity. The guide block is provided with a guide channel, one end of which communicates with the through hole and the other end of which faces the limiting member. The end of the guide channel communicating with the through hole has an annular flange. The side of the annular flange facing away from the through hole forms an intracavity limiting surface. The limiting pin passes through the guide channel, and the elastic member is sleeved outside the limiting pin and located inside the guide channel.

[0014] This utility model also provides a KVM all-in-one machine, including an internal structure and the aforementioned KVM all-in-one machine locking structure, wherein the internal structure is disposed in the panel and the housing.

[0015] The present invention achieves the following technical advantages over the prior art:

[0016] The KVM all-in-one machine locking structure and the KVM all-in-one machine provided by this utility model have a first locking structure and a second locking structure respectively set at both ends of the panel. Compared with setting a locking structure only at one end of the panel, this increases the limit between the panel and the box when the panel is closed, reduces the relative displacement between the panel and the box, and can meet the vibration uniformity requirements. Moreover, when the knob is rotated to the first or second state, the user can release the operating knob and perform other operations. This is more convenient to use than the locking structure that requires constantly pushing the operating lever during the opening and closing of the panel. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The purpose of this invention is to provide a locking structure for a KVM switch and a KVM switch, so as to solve the problems existing in the prior art, improve reliability, reduce vibration, and make operation more convenient.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] This embodiment provides a locking structure for a KVM all-in-one machine, such as... Figure 1-10 As shown, the device includes: a panel 1, a housing 2, a first locking structure 3, and a second locking structure 4. The panel 1 is rotatably connected to the housing 2. The first locking structure 3 and the second locking structure 4 are respectively located at both ends of the panel 1. Both the first locking structure 3 and the second locking structure 4 include a knob 5 and a limiting pin 6. Both knobs 5 are rotatably connected to the panel 1. The limiting pin 6 is located inside the panel 1. The housing 2 has two holes, which correspond to the positions of the two limiting pins 6. The knob 5 has at least a first state and a second state. When the panel 1 is closed on the housing 2 and the knob 5 is in the first state and held, the knob 5 allows the limiting pin 6 to extend into the hole. When the knob 5 is rotated to the second state and held, the limiting pin 6 can be pulled out of the hole, and the panel 1 can rotate relative to the housing 2 and unfold.

[0034] The KVM all-in-one machine locking structure provided in this embodiment allows the limiting pin 6 to extend into the hole on the box 2 when the panel 1 rotates relative to the box 2 and closes onto the box 2. This is achieved by simultaneously turning the knobs 5 on the first locking structure 3 and the second locking structure 4 to the first state, thereby limiting the relative rotation between the panel 1 and the box 2 and locking the panel 1. When it is necessary to open the panel 1, simultaneously turning the knobs 5 on the first locking structure 3 and the second locking structure 4 to the second state allows the limiting pin 6 to be pulled out of the hole on the box. At this time, the lock between the panel 1 and the box 2 is released, and the panel 1 can rotate relative to the box 2 and be opened. By providing the first locking structure 3 and the second locking structure 4 at both ends of the panel 1, compared to providing a locking structure only at one end of the panel 1, the limiting between the panel 1 and the box 2 when they are closed is increased, the relative displacement between the panel 1 and the box 2 is reduced, and vibration is reduced, which can meet the relevant vibration requirements in the GJB150 standard. Moreover, as long as the knob 5 is not turned, the limit pin 6 can always remain in the state of being inserted into or extended out of the hole. When the knob 5 is rotated to the first or second state, the user can release the hand operating the knob 5 and perform other operations. This is more convenient to use than the locking structure that requires constantly pushing the operating lever during the opening and closing of the panel 1.

[0035] In this embodiment, both the first locking structure 3 and the second locking structure 4 further include a limiting member 7 and an elastic member 8. The panel 1 has a receiving cavity. The limiting pin 6, the limiting member 7, and the elastic member 8 are all disposed within the receiving cavity. The limiting pin 6 has a pin-shaft limiting surface 13, and the receiving cavity has an inner cavity limiting surface 26. The pin-shaft limiting surface 13 and the inner cavity limiting surface 26 are arranged opposite to each other. The two ends of the elastic member 8 respectively abut against the pin-shaft limiting surface 13 and the inner cavity limiting surface 26. A through hole 23 is provided on one side of the receiving cavity, and the through hole 23 can correspond to the position of the hole. The knob 5 is rotatably connected to the panel 1 around a first rotating shaft, which is perpendicular to the limiting pin 6. The axis is oriented, and one end of the knob 5 extends into the receiving cavity and is fixedly connected to the limiting member 7. The limiting member 7 has a first position 9 and a second position 10. The first position 9 is farther away from the first rotating shaft than the second position 10. The end of the limiting pin 6 away from the through hole 23 is the first end 11. The knob 5 can rotate and drive the limiting member 7 to rotate. When the knob 5 is rotated to the first state, the first position 9 contacts the first end 11, and the limiting pin 6 can be pushed out of the through hole 23 by the first position 9 and extend into the hole. When the knob 5 is rotated to the second state, the limiting pin 6 can be pulled out of the hole and retracted into the receiving cavity under the rebound action of the elastic member 8, and the second position 10 can contact the first end 11. By rotating knob 5 to the first state, the first position 9 of the limiting member 7 pushes out the limiting pin 6. The limiting pin 6 can remain extended and compress the elastic member 8. One end of the limiting pin 6 can then be inserted into the hole and lock the panel 1 and the box 2. By rotating knob 5 to the second state, the limiting pin 6 can be pulled out of the hole under the rebound of the elastic member, so that the second position 10 of the limiting member 7 contacts the first end 11 of the limiting pin 6, thereby releasing the lock between the box 2 and the panel 1.

[0036] In this embodiment, the limiting member 7 includes a first portion 12. The first portion 12 has a partially elliptical cross-section perpendicular to the first axis of rotation. The vertex of the first portion 12 on the major axis of the ellipse forms a first position 9, and the vertex of the first portion 12 on the minor axis of the ellipse forms a second position 10. The limiting member 7 is fixedly connected to the knob 5, and the first axis of rotation passes through the center point of the first portion 12. By setting the first portion 12 of the ellipse as an ellipse, and using the vertex on the major axis of the ellipse as the first position 9 and the vertex on the minor axis of the ellipse as the second position 10, the limiting member 7 can control the extension and retraction of the limiting pin. Moreover, the line connecting the first position 9 and the second position 10 is a smooth curve, which can reduce friction to facilitate the rotation of the knob 5.

[0037] In this first embodiment, the limiting member 7 also has a first limiting surface 14 and a second limiting surface 15, and the receiving cavity also has a third limiting surface 16 and a fourth limiting surface 17. The first limiting surface 14, the second limiting surface 15, the third limiting surface 16, and the fourth limiting surface 17 are all parallel to the first rotating shaft. The first limiting surface 14 is parallel to the second limiting surface 15, and the third limiting surface 16 is perpendicular to the fourth limiting surface 17. When the knob 5 is rotated to the first state, the first limiting surface 14 can contact the third limiting surface 16. When the knob 5 is rotated to the second state, the second limiting surface 15 can contact the fourth limiting surface 17. By setting the first limiting surface 14, the second limiting surface 15, the third limiting surface 16, and the fourth limiting surface 17, the limiting member 7 can rotate only within the range between the first state and the second state.

[0038] In this first embodiment, both the first locking structure 3 and the second locking structure 4 further include a locking sleeve 18. The panel 1 has a mounting hole 19 communicating with the receiving cavity and the outside. The locking sleeve 18 is fixedly connected within the mounting hole 19. The locking sleeve 18 has an insertion hole 20. The knob 5 passes through the insertion hole 20 and extends into the receiving cavity. The inner side of the insertion hole 20 fits against the outer side of the knob 5. The locking sleeve 18 and the mounting hole 19 are interference-fitted, reducing installation difficulty. Simultaneously, the fit between the inner side of the insertion hole 20 and the outer side of the knob 5 makes the connection between the knob 5 and the panel 1 more stable.

[0039] In this first embodiment, the locking sleeve 18 and the mounting hole 19 form an interference fit. When installing the locking sleeve 18, installation is completed simply by pressing the locking sleeve 18 into the mounting hole 19, which is simpler than welding or other fixed connections between the locking sleeve 18 and the mounting hole 19. Both the locking sleeve 18 and the panel 1 are made of metal; the locking sleeve 18 is preferably made of steel, and the panel 1 is made of aluminum.

[0040] In this first embodiment, the knob 5 has a plug-in portion 24, the cross-section of which is rectangular along the first axis of rotation. The limiting member 7 has a plug-in hole 25, which is rectangular, and the plug-in portion 24 can be inserted into the plug-in hole 25. By matching and plugging the rectangular plug-in portion 24 into the rectangular hole, the limiting member 7 and the knob 5 are circumferentially limited, preventing the limiting member 7 from rotating relative to the knob 5.

[0041] In this first embodiment, the elastic element 8 is a spring. Springs have a simple structure, are easy to manufacture and process, and are inexpensive.

[0042] In this embodiment, both the first locking structure 3 and the second locking structure 4 further include a guide block 21, which is fixedly connected to the receiving cavity. A guide channel 22 is provided on the guide block 21. One end of the guide channel 22 communicates with the through hole 23, and the other end faces the limiting member 7. The end of the guide channel 22 communicating with the through hole 23 has an annular flange. The side of the annular flange facing away from the through hole 23 forms an in-cavity limiting surface 26. The limiting pin 6 passes through the guide channel 22, and the elastic member 8 is sleeved outside the limiting pin 6 and located within the guide channel 22. The guide channel 22 can restrict the movement trajectory of the limiting pin 6, thereby allowing the limiting pin 6 to move along the guide channel 22 under the control of the limiting member 7 and the elastic member 8, preventing the limiting pin 6 from changing angle and failing to extend into the hole on the box body 2.

[0043] Example 2

[0044] This embodiment provides a KVM all-in-one machine, including an internal structure and the KVM all-in-one machine locking structure in Embodiment 1. The internal structure is set inside the panel 1 and the box 2.

The internal structure refers to all other structures in a KVM all-in-one machine known to the inventor, excluding the KVM all-in-one machine locking structure, such as: LED screen, keyboard, motherboard, etc.
