Threshold stopper applied to energy storage cabinet or liquid cooling cabinet

Abstract

This utility model relates to the field of limiters, specifically a door limiter applied to energy storage cabinets or liquid-cooled cabinets. It includes a positioning bracket for connecting to the cabinet body, a door limiting tube for connecting to the cabinet door, and a connecting rod. The door limiting tube has a guide groove penetrating its inner and outer surfaces, a mounting hole, a first limiting hole, and a second limiting hole. When the door limiting tube is connected to the cabinet door and the positioning bracket is connected to the cabinet body, the movement path of the second pin is restricted within the contour formed by the guide groove, the first limiting hole, and the second limiting hole. The distance between the mounting hole and the positioning bracket is greater than the distance between the first limiting hole and the positioning bracket, and also greater than the distance between the second limiting hole and the positioning bracket. During the opening of the cabinet door relative to the cabinet body, as the angle between the cabinet door and the cabinet body gradually increases, the distance between the second pin and the mounting hole gradually increases until the second pin slides into the second limiting position and terminates its movement, thereby preventing the second pin on the connecting rod from dislodging from the mounting hole.

Description

Technical Field

[0001] This utility model relates to the field of limiters, specifically a door limiter applied to energy storage cabinets or liquid-cooled cabinets. Background Technology

[0002] In the prior art, there is a patent document entitled "A Detachable Multi-Limiting Point Cabinet Door Limiting Device", with application number 201320894159.3. In this prior art, a limiter is specifically used, which is formed by a structure such as a strip slide rail and a pull rod. The strip slide rail is provided with multiple limiting points, so that the cabinet door can be opened through a certain limiting point and limited to a corresponding angle relative to the cabinet.

[0003] In the aforementioned prior art, multiple limiting points and release holes are located at the same end or side of the strip rail. When the cabinet door is adjusted to an excessive angle relative to the cabinet, the strip rail and the pull rod can separate from each other. This results in the cabinet door losing its angle-limiting function relative to the cabinet when the operator does not notice the separation of the strip rail and the pull rod.

[0004] Therefore, when the cabinet door is adjusted to an excessive angle relative to the cabinet, how to prevent the strip rail and the pull rod from separating from each other, so as to maintain the limiting angle function of the cabinet door relative to the cabinet, becomes a technical problem to be solved. Utility Model Content

[0005] To address the technical problem of preventing the strip rail and pull rod from separating when the cabinet door is adjusted to an excessive angle relative to the cabinet, and thus maintaining the cabinet door at a limited angle, this utility model provides a door limiter for energy storage cabinets or liquid-cooled cabinets.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] According to one aspect of the present invention, a door limiter for use in energy storage cabinets or liquid-cooled cabinets is provided, comprising a positioning bracket for connecting the cabinet body, a door limit tube for connecting the cabinet door, and a connecting rod.

[0008] The door limiting tube is provided with a guide groove, a mounting hole, a first limiting hole, and a second limiting hole that "penetrate the inner and outer surfaces of the door limiting tube". The mounting hole is located at one end of the guide groove, the second limiting hole is located at the other end of the guide groove, and the first limiting hole is located between the mounting hole and the second limiting hole. The outlines of the mounting hole, the first limiting hole, and the second limiting hole intersect with the outline of the guide groove, respectively.

[0009] The connecting rod has a head end and a tail end. The head end is detachably and rotatably connected to the positioning bracket via a first pin, and the tail end is movably and rotatably connected to the door limiting tube via a second pin. The second pin is inserted into the contour formed by the guide groove, the mounting hole, the first limiting hole, and the second limiting hole. When the door limiting tube is connected to the cabinet door and the positioning bracket is connected to the cabinet body, the movement path of the second pin is restricted within the contour formed by the guide groove, the first limiting hole, and the second limiting hole.

[0010] Furthermore, the connecting rod is provided with a first connecting hole, which is located at the head end of the connecting rod;

[0011] The positioning bracket is provided with a second connection hole;

[0012] The first pin has a first connecting end and a second connecting end at its two ends. The first connecting end forms an interference fit with the first connecting hole, and the second connecting end penetrates the second connecting hole. The first pin forms a clearance fit with the second connecting hole. The first pin is provided with a locking through hole located at the second connecting end. The locking through hole is detachably provided with an open locking pin.

[0013] Furthermore, the connecting rod is provided with a third connecting hole, which is located at the tail end of the connecting rod;

[0014] The second pin includes a head section, a positioning section, a sliding section, and a tail section that are coaxially connected to each other. The minimum width of the head section is greater than the diameter of the positioning section, the diameter of the positioning section is greater than the diameter of the sliding section, and the diameter of the sliding section is greater than the diameter of the tail section.

[0015] The pin tail section forms a threaded connection with the third connecting hole. The pin head section, the positioning section, and the sliding section are respectively inserted into the door limiting tube through the mounting hole. The connecting rod has an initial state in which it does not deform when it loses external force and a working state in which it deforms when it is subjected to external force. When the positioning section forms a clearance fit with the first limiting hole or the second limiting hole, the connecting rod is in the initial state. When the sliding section forms a clearance fit with the guide groove, the connecting rod is in the working state.

[0016] Furthermore, the positioning bracket includes a top plate, a bottom plate, a first side plate, and a second side plate;

[0017] The base plate is connected to the first side plate and the second side plate respectively. The first side plate and the second side plate are parallel to each other. The first side plate is provided with a first preset hole for connecting to the cabinet body. The first preset hole is for bolts to be inserted.

[0018] The top plate is connected to the second side plate, wherein the second connecting hole is located on the top plate.

[0019] Furthermore, the door limiting tube includes a first plate-shaped portion, a second plate-shaped portion, a third plate-shaped portion, and a fourth plate-shaped portion. The first plate-shaped portion to the fourth plate-shaped portion are connected end to end to form a rectangular tube shape. The first plate-shaped portion and the third plate-shaped portion are parallel to each other, the second plate-shaped portion and the fourth plate-shaped portion are parallel to each other, and the first plate-shaped portion to the fourth plate-shaped portion together form an installation cavity.

[0020] The first plate-shaped portion and / or the third plate-shaped portion are provided with the guide groove, the mounting hole, the first limiting hole and the second limiting hole;

[0021] One of the plate-shaped portions of the second plate-shaped portion and the fourth plate-shaped portion is provided with a second preset hole for connecting the cabinet door, and the other plate-shaped portion of the second plate-shaped portion and the fourth plate-shaped portion is provided with a process hole. The second preset hole and the process hole are respectively used for bolt insertion, wherein the process hole is coaxially arranged with the second preset hole, and the diameter of the process hole is larger than the diameter of the second preset hole.

[0022] Furthermore, the connecting rod includes a first segment and a second segment, which are integrally formed, and the included angle between the first segment and the second segment is an obtuse angle.

[0023] Furthermore, when the second pin is located within the first limiting hole, the angle between the door limiting tube and the positioning bracket is 90 degrees.

[0024] When the second pin is located in the second limiting hole, the angle between the door limiting tube and the positioning bracket is 135 degrees.

[0025] The above technical solution has the following advantages or beneficial effects:

[0026] The door limiter provided by this utility model for energy storage cabinets or liquid-cooled cabinets has a first limit hole, a second limit hole, and a mounting hole on the door limit tube. The distance between the mounting hole and the positioning bracket is greater than the distance between the first limit hole and the positioning bracket, and also greater than the distance between the second limit hole and the positioning bracket. This causes the distance between the second pin and the mounting hole 22 to gradually increase as the angle between the door and the cabinet body gradually increases during the opening process of the cabinet door relative to the cabinet body, until the second pin slides into the second limit and stops moving. This prevents the second pin on the connecting rod from coming out of the mounting hole, and thus prevents the connecting rod from separating from the door limit tube. Attached Figure Description

[0036] Example 1:

[0037] To address the technical problem of preventing the strip rail and pull rod from separating when the cabinet door is adjusted to an excessive angle relative to the cabinet, and thus maintaining the cabinet door at a limited angle, this utility model provides a door limiter for energy storage cabinets or liquid-cooled cabinets.

[0038] For details, see Figures 1 to 5 The door limiter 100 of this embodiment, which is applied to energy storage cabinets or liquid cooling cabinets, includes a positioning bracket 1 for connecting the cabinet body 200, a door limit tube 2 for connecting the cabinet door 300, and a connecting rod 3.

[0039] The door limiting tube 2 is provided with a guide groove 21 that "penetrates the inner and outer surfaces of the door limiting tube 2", a mounting hole 22, a first limiting hole 23 and a second limiting hole 24. The mounting hole 22 is located at one end of the guide groove 21, the second limiting hole 24 is located at the other end of the guide groove 21, and the first limiting hole 23 is located between the mounting hole 22 and the second limiting hole 24. The outlines of the mounting hole 22, the first limiting hole 23 and the second limiting hole 24 intersect with the outline of the guide groove 21 respectively.

[0040] The two ends of the connecting rod 3 are a head end A1 and a tail end A2. The head end A1 is detachably and rotatably connected to the positioning bracket 1 via a first pin 4. The tail end A2 is movably and rotatably connected to the door limiting tube 2 via a second pin 5. The second pin 5 is inserted into the contour formed by the guide groove 21, the mounting hole 22, the first limiting hole 23, and the second limiting hole 24. When the door limiting tube 2 is connected to the cabinet door 300 and the positioning bracket 1 is connected to the cabinet body 200, the movement path of the second pin 5 is restricted within the contour formed by the guide groove 21, the first limiting hole 23, and the second limiting hole 24.

[0041] In this embodiment, see Figure 1 or Figure 2 The positioning bracket 1 is installed at the lower part of the cabinet 200. Specifically, the cabinet 200 has a front facing the staff. The front of the cabinet 200 is provided with a cabinet opening for installing electrical components. This makes the front of the cabinet 200 form four side panel structures located at the top, bottom, left and right. The positioning bracket 1 is set in the lower side panel structure.

[0042] In this embodiment, see Figure 1 or Figure 2 The door limit tube 2 is installed on the cabinet door 300. Specifically, the cabinet door 300 is hinged to the aforementioned cabinet body 200. When the cabinet door 300 completely covers the cabinet opening of the cabinet body 200, the side of the cabinet door 300 facing the cabinet body 200 is the inner surface, and the side of the cabinet door 300 away from the cabinet body 200 is the outer surface. The door limit tube 2 is installed on the inner surface of the cabinet door 300, and the door limit tube 2 is located near the bottom of the cabinet door 300.

[0043] In this embodiment, see Figure 4When the door limit tube 2 is installed on the cabinet door 300 and the positioning bracket 1 is installed on the cabinet body 200, along the vertical direction of the cabinet body 200, the bottom of the door limit tube 2 and the top of the positioning bracket 1 form a gap to accommodate the connecting rod 3. This makes the connecting rod 3 itself horizontal and is set between the door limit tube 2 and the positioning bracket 1 in the vertical direction, avoiding interference between the connecting rod 3 and the door limit tube 2 and / or the positioning bracket 1.

[0044] In this embodiment, during the assembly of the positioning bracket 1, the connecting rod 3 and the door limiting tube 2, the positioning bracket 1 is first connected to the cabinet door 300, and the door limiting tube 2 is connected to the cabinet door 300. At this time, the distance between the mounting hole 22 on the door limiting tube 2 and the positioning bracket 1 is greater than the distance between the first limiting hole 23 and the positioning bracket 1, and the distance between the first limiting hole 23 and the positioning bracket 1 is greater than the distance between the second limiting hole 24 and the positioning bracket 1.

[0045] Then, the connecting rod 3 is connected to the door limit tube 2 via the second pin 5. Specifically, the second pin 5 is first inserted into the mounting hole 22. At this time, the distance between the second pin 5 and the positioning bracket 1 is the largest. Then, the second pin 5 and the connecting rod 3 are slid along the guide groove 21 toward the position of the first limit hole 23 or the second limit hole 24, so that the distance between the second pin 5 and the positioning bracket 1 gradually decreases.

[0046] Next, when the second pin 5 and the connecting rod 3 slide relative to the guide groove 21 to a position close to the first limiting hole 23, or to the position of the first limiting hole 23, or to the position between the first limiting hole 23 and the second limiting hole 24, or to the position of the second limiting hole 24, the operator can connect the connecting rod 3 to the positioning bracket 1 through the first pin 4.

[0047] When the door limiter 100 of this embodiment is actually used in energy storage cabinets or liquid cooling cabinets, before the staff opens the cabinet door 300, the cabinet door 300 completely covers the cabinet opening of the cabinet body 200. At this time, the distance between the second pin 5 on the connecting rod 3 and the mounting hole 22 is the smallest, and correspondingly, the distance between the second pin 5 and the second limit hole 24 is the largest. The second pin 5 is located in the guide groove 21 between the mounting hole 22 and the first limit hole 23.

[0048] Afterwards, the staff opened the cabinet door 300. As the angle between the cabinet door 300 and the cabinet body 200 continued to increase, the second pin 5 slid relative to the guide groove 21, and the distance between the second pin 5 and the mounting hole 22 gradually increased. Correspondingly, the distance between the second pin 5 and the second limiting hole 24 gradually decreased.

[0049] Then, when the second pin 5 moves to the position of the first limiting hole 23, the second pin 5 is engaged in the first limiting hole 23, forming the first limiting angle;

[0050] If the operator needs to further increase the angle between the cabinet door 300 and the cabinet body 200, the operator applies force to the connecting rod 3, causing the second pin 5 to change from being engaged in the first limiting hole 23 to being unengaged from the first limiting hole 23. At this time, the operator can continue to increase the angle between the cabinet door 300 and the cabinet body 200, causing the second pin 5 to continue sliding in the guide groove 21. During the continued sliding, the distance between the second pin 5 and the mounting hole 22 continues to increase, and correspondingly, the distance between the second pin 5 and the second limiting hole 24 continues to decrease, until the second pin 5 moves to the position of the second limiting hole 24 and is engaged in the second limiting hole 24, forming the second limiting angle.

[0051] It should be understood that the door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet in this embodiment has a first limiting hole 23 and a second limiting hole 24 in its door limiting tube 2. Therefore, when the second pin 5 is engaged with the second limiting hole 24, the angle between the cabinet door 300 and the cabinet body 200 is at its maximum angle. This causes the angle between the cabinet door 300 and the cabinet body 200 to be limited to the maximum angle by the door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet in this embodiment.

[0052] However, in other embodiments, if the door limiting tube 2 is sequentially provided with a first limiting hole 23, a second limiting hole 24, a third limiting hole... and an Nth limiting hole, then in other embodiments, when the second pin 5 is engaged with the second limiting hole 24, the angle between the cabinet door 300 and the cabinet body 200 is not the maximum angle.

[0053] When using the door limiter 100 of this embodiment applied to energy storage cabinets or liquid-cooled cabinets, when the operator needs to close the cabinet door 300, the operator applies force to the connecting rod 3, causing the second pin 5 to change from being engaged in the first limiting hole 23 or the second limiting hole 24 to being engaged in contact with the first limiting hole 23 or the second limiting hole 24. At this time, the operator can reduce the angle of the push door relative to the cabinet body 200, causing the second pin 5 to slide in the guide groove 21. During the sliding process, the distance between the second pin 5 and the mounting hole 22 gradually decreases, and correspondingly, the distance between the second pin 5 and the second limiting hole 24 gradually increases until the cabinet door 300 completely covers the cabinet opening of the cabinet body 200. At this time, the distance between the second pin 5 and the mounting hole 22 is the smallest, and correspondingly, the distance between the second pin 5 and the second limiting hole 24 is the largest, and the second pin 5 is located in the guide groove 21 between the mounting hole 22 and the first limiting hole 23.

[0054] In the prior art (titled: A detachable multi-limiting-point cabinet door limiting device, application number: 201320894159.3), the strip slide rail (equivalent to the door limiting tube 2 in this application) is provided with multiple limiting points (equivalent to the first limiting hole 23 and the second limiting hole 24 in this application) and disengagement holes (equivalent to the mounting holes 22 in this application). The distance between the disengagement hole and the pull rod shaft (equivalent to the positioning bracket 1 in this application) is smaller than the distance between each limiting point and the pull rod shaft. As a result, during the opening of the cabinet door relative to the cabinet, as the angle of the cabinet door relative to the cabinet gradually increases, the distance between the slider on the pull rod (equivalent to the second pin 5 in this application) and the disengagement hole gradually decreases until the slider slides to the disengagement hole, at which point the slider disengages from the disengagement hole, thus separating the pull rod from the strip slide rail.

[0055] The door limiter 100 of this embodiment, applied to energy storage cabinets or liquid-cooled cabinets, has a first limiting hole 23, a second limiting hole 24, and a mounting hole 22 on the door limiting tube 2. The distance between the mounting hole 22 and the positioning bracket 1 is greater than the distance between the first limiting hole 23 and the positioning bracket 1, and also greater than the distance between the second limiting hole 24 and the positioning bracket 1. This causes the distance between the second pin 5 and the mounting hole 22 to gradually increase as the angle between the door 300 and the cabinet body 200 gradually increases during the opening process of the cabinet door 300 relative to the cabinet body 200, until the second pin 5 slides into the second limiting hole 24 and stops moving. This prevents the second pin 5 on the connecting rod 3 from coming out of the mounting hole 22, and thus prevents the connecting rod 3 from separating from the door limiting tube 2.

[0056] Therefore, the door limiter 100 applied to energy storage cabinets or liquid-cooled cabinets in this embodiment solves the technical problem of how to prevent the strip rail and the pull rod from separating when the cabinet door is adjusted to an excessive angle relative to the cabinet, so as to maintain the limiting angle function of the cabinet door relative to the cabinet.

[0057] Furthermore, in the aforementioned scheme, the preferred technical solution for forming a detachable and rotatable connection between the connecting rod 3 and the positioning bracket 1 is as follows.

[0058] See Figure 6 , Figure 7 or Figure 8 In this embodiment, the door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet has a first connecting hole 31 on the connecting rod 3, which is located at the head end A1 of the connecting rod 3.

[0059] The positioning bracket 1 is provided with a second connecting hole 11;

[0060] The two ends of the first pin 4 are a first connecting end 41 and a second connecting end 42, respectively. The first connecting end 41 forms an interference fit with the first connecting hole 31, and the second connecting end 42 penetrates the second connecting hole 11. The first pin 4 forms a clearance fit with the second connecting hole 11. The first pin 4 is provided with a locking through hole 43, which is located at the second connecting end 42. The locking through hole 43 is detachably provided with an open locking pin 5.

[0061] When assembling the door limiter 100 of this embodiment for use in energy storage cabinets or liquid-cooled cabinets, the operator first installs the door limit tube 2 onto the cabinet door 300 and the positioning bracket 1 onto the cabinet body 200. Then, after connecting the connecting rod 3 to the door limit tube 2 via the second pin 5, the operator slides the connecting rod 3 and the second pin 5 from the mounting hole 22 of the door limit tube 2 to the position of the first limit hole 23, or the position of the second limit hole 24, or a position between the first limit hole 23 and the second limit hole 24, so that... The first pin 4 on the connecting rod 3 can reach the position of the positioning bracket 1; then, the worker inserts the first pin 4 on the connecting rod 3 into the second connecting hole 11 of the positioning bracket 1. At this time, the first pin 4 is inserted into the first connecting hole 31 and the second connecting hole 11 respectively. Finally, the worker inserts the open locking pin 5 into the locking through hole 43 on the first pin 4, and bends a part of the open locking pin 5 with a simple tool (such as pliers), thus completing the assembly of the door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet in this embodiment.

[0062] Since the first pin 4 and the first connecting hole 31 of the connecting rod 3 form an interference fit, and since the part of the positioning bracket 1 where the second connecting hole 11 is located is restricted between the connecting rod 3 and the open locking pin 5, a detachable connection structure between the connecting rod 3 and the first pin 4 is formed relative to the positioning bracket 1 through the detachable connection structure between the open locking pin 5 and the first pin 4.

[0063] Furthermore, since the first pin 4 and the second connecting hole 11 form a clearance fit, the first pin 4 forms a rotatable connection structure relative to the positioning bracket 1. During the opening of the cabinet door 300 relative to the cabinet body 200, as the angle between the cabinet door 300 and the cabinet body 200 continuously increases, the connecting rod 3, driven by the cabinet door 300 and the door limit tube 2, on the one hand, the connecting rod 3 forms a sliding motion tendency relative to the guide groove 21 on the door limit tube 2 through the second pin 5, and on the other hand, the connecting rod 3 forms a rotational motion tendency relative to the positioning bracket 1 through the first pin 4, thus the first pin 4 forms a rotational function relative to the positioning bracket 1.

[0064] Furthermore, in the aforementioned scheme, the following technical solutions are preferred to be adopted to determine how the connecting rod 3 forms a sliding motion tendency relative to the guide groove 21 of the door limiting tube 2, and how the connecting rod 3 forms a limiting state relative to the first limiting hole 23 and the second limiting hole 24 of the door limiting tube 2.

[0065] See Figure 5 , Figure 6 or Figure 9 In this embodiment, the door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet has a third connecting hole 32 on the connecting rod 3, which is located at the tail end A2 of the connecting rod 3.

[0066] The second pin 5 includes a pin head section 51, a positioning section 52, a sliding section 53, and a pin tail section 54 that are coaxially connected to each other. The minimum width of the pin head section 51 is greater than the diameter of the positioning section 52, the diameter of the positioning section 52 is greater than the diameter of the sliding section 53, and the diameter of the sliding section 53 is greater than the diameter of the pin tail section 54.

[0067] The pin tail section 54 forms a threaded connection with the third connecting hole 32. The pin head section 51, the positioning section 52 and the sliding section 53 are respectively inserted into the door limit tube 2 through the mounting hole 22. The connecting rod 3 has an initial state without deformation when it loses external force and a working state with deformation when it is subjected to external force. When the positioning section 52 forms a clearance fit with the first limit hole 23 or the second limit hole 24 respectively, the connecting rod 3 is in the initial state. When the sliding section 53 forms a clearance fit with the guide groove 21, the connecting rod 3 is in the working state.

[0068] When actually assembling the door limiter 100 of this embodiment for use in energy storage cabinets or liquid-cooled cabinets, the operator first installs the door limit tube 2 on the cabinet door 300 and the positioning bracket 1 on the cabinet body 200. Then, the operator threadedly connects the pin tail section 54 of the second pin 5 to the third connecting hole 32 of the connecting rod 3. The pin tail section 54 of the second pin 5 is machined with external threads, and the corresponding third connecting hole 32 is machined with internal threads. After the second pin 5 is connected to the connecting rod 3, the operator inserts the second pin 5 into the mounting hole 22 of the door limiter 100 for use in energy storage cabinets or liquid-cooled cabinets.

[0069] In actual use of this embodiment, when the cabinet door 300 is completely covered by the cabinet opening of the cabinet body 200, the second pin 5 is located in the guide groove 21 between the mounting hole 22 and the first limiting hole 23. At this time, the sliding section 53 of the second pin 5 forms a clearance fit with the guide groove 21, while the pin head section 51, the positioning section 52 and the pin tail section 54 are located outside the guide groove 21 respectively. Furthermore, the connecting rod 3 itself is in a working state, which causes the connecting rod 3 to generate elastic force and force the positioning section 52 to contact the inner surface of the door limiting tube 2 used to limit the guide groove 21.

[0070] Then, the staff opens the cabinet door 300, so that the angle between the cabinet door 300 and the cabinet body 200 gradually increases. The sliding section 53 of the second pin 5 slides in the guide groove 21 until the second pin 5 moves to the first limiting hole 23. Under the elastic force of the connecting rod 3 itself, the connecting rod 3 changes from the working state to the initial state and drives the second pin 5 to move. Its movement direction is along the direction from the pin head section 51 to the pin tail section 54. This causes the sliding section 53 of the second pin 5 to move out of the first limiting hole 23, and the positioning section 52 of the second pin 5 to be inserted into the first limiting hole 23 until the pin head section 51 of the second pin 5 is blocked by the inner surface of the door limiting tube 2, so that the second pin 5 stops moving. At this time, the connecting rod 3 has returned to the initial state, and the positioning section 52 of the second pin 5 is engaged in the first limiting hole 23.

[0071] Next, if it is necessary to continue opening the cabinet door 300, the operator applies a vertically upward force to the connecting rod 3, causing the connecting rod 3 to change from its initial state to its working state. On the one hand, this causes the connecting rod 3 to generate elastic force again, and on the other hand, the connecting rod 3 drives the second pin 5 to move again. The direction of movement is along the direction from the pin tail section 54 to the pin head section 51. This causes the positioning section 52 of the second pin 5 to move out of the first limiting hole 23, while the sliding section 53 of the second pin 5 is inserted into the first limiting hole 23. At this time, the operator can continue to open the cabinet door 300, causing the sliding section 53 of the second pin 5 to move from the position located in the first limiting hole 23 to the position between the first limiting hole 23 and the second limiting hole 24, or to move the sliding section 53 of the second pin 5 from the position located in the first limiting hole 23 to the position between the mounting hole 22 and the first limiting hole 23.

[0072] Similarly, if the operator opens the cabinet door 300 and causes the second pin 5 to move to the second limiting hole 24, the second pin 5, under the elastic force of the connecting rod 3, will move along the direction from the pin head section 51 to the pin tail section 54, thereby enabling the connecting rod 3 to be engaged into the second limiting hole 24 through the positioning section 52 of the second pin 5. Conversely, if the operator applies a vertically upward force to the connecting rod 3, the second pin 5, driven by the connecting rod 3, will move along the direction from the pin tail section 54 to the pin head section 51, causing the positioning section 52 of the second pin 5 to move out of the second limiting hole 24. The rest is described in the previous description of the second pin 5 and the first limiting hole 23, and will not be repeated here.

[0073] Further, see Figure 7 The door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet in this embodiment includes a top plate 12, a bottom plate 13, a first side plate 14 and a second side plate 15.

[0074] The base plate 13 is connected to the first side plate 14 and the second side plate 15 respectively. The first side plate 14 and the second side plate 15 are parallel to each other. The first side plate 14 is provided with a first preset hole 16 for connecting the cabinet 200. The first preset hole 16 is used for bolt insertion.

[0075] The top plate 12 is connected to the second side plate 15, wherein the second connecting hole 11 is located on the top plate 12.

[0076] The first side plate 14 is used to connect the cabinet 200. Specifically, the first side plate 14 is provided with a first preset hole 16. Correspondingly, the cabinet 200 is provided with a mounting through hole that matches the first preset hole 16. After the bolts are inserted into the first preset hole 16 and the mounting through hole respectively, the positioning bracket 1 and the cabinet 200 can be clamped by connecting the bolts and nuts, thus completing the connection between the positioning bracket 1 and the cabinet 200.

[0077] The function of the base plate 13 is to form a gap between the first side plate 14 and the second side plate 15, and to form a support structure between the second side plate 15 and the top plate 12 relative to the first side plate 14. Since the first side plate 14 and the second side plate 15 form a gap, the top plate 12 is restricted between the first side plate 14 and the second side plate 15, preventing the top plate 12 from extending from the inside of the cabinet 200 to the outside of the cabinet 200 and interfering with the movement path of the cabinet door 300.

[0078] The function of the second side plate 15 is to support the top plate 12 and keep the top plate 12 within a preset height. This requires that the top plate 12 and the door limit tube 2 have a gap that can be formed for installing the connecting rod 3. Specifically, when the door limit tube 2 is installed on the cabinet door 300 and the positioning bracket 1 is installed on the cabinet body 200, the gap between the ground of the door limit tube 2 and the top edge of the first side plate 14 can accommodate the connecting rod 3.

[0079] The top plate 12 is provided with the aforementioned second connecting hole 11, and forms a rotatable and detachable connection with the aforementioned first pin 4 through the second connecting hole 11.

[0080] Furthermore, participate Figure 5 The door limiter 100 applied to energy storage cabinets or liquid cooling cabinets in this embodiment includes a door limit tube 2 comprising a first plate-shaped portion 211, a second plate-shaped portion 212, a third plate-shaped portion 213, and a fourth plate-shaped portion 214. The first plate-shaped portion 211 to the fourth plate-shaped portion 214 are connected end to end to form a rectangular tube shape. The first plate-shaped portion 211 and the third plate-shaped portion 213 are parallel to each other, and the second plate-shaped portion 212 and the fourth plate-shaped portion 214 are parallel to each other. The first plate-shaped portion 211 to the fourth plate-shaped portion 214 together form a mounting cavity.

[0081] The first plate-shaped portion 211 and / or the third plate-shaped portion 213 are provided with a guide groove 21, a mounting hole 22, a first limiting hole 23 and a second limiting hole 24;

[0082] One of the plate-shaped portions 212 and 214 is provided with a second preset hole 215 for connecting the cabinet door 300, and the other plate-shaped portion 212 and 214 is provided with a process hole 216. The second preset hole 215 and the process hole 216 are respectively used for bolt insertion. The process hole 216 is coaxially arranged with the second preset hole 215, and the diameter of the process hole 216 is larger than the diameter of the second preset hole 215.

[0083] In this embodiment, the first plate-shaped portion 211 to the fourth plate-shaped portion 214 can be considered to be arranged in a clockwise direction or in a counterclockwise direction. When the door limit tube 2 is actually installed on the cabinet door 300, the first plate-shaped portion 211 is located above the third plate-shaped portion 213.

[0084] The structure of the gate limiting tube 2 formed by the first plate-shaped portion 211 to the fourth plate-shaped portion 214 arranged in a clockwise direction will be described below:

[0085] From the perspective of the specific gate limit tube 2, the gate limit tube 2 can be configured with the following structures:

[0086] In the first structure, the door limiting tube 2 is a rectangular tube as a whole, and a guide groove 21, a mounting hole 22, a first limiting hole 23 and a second limiting hole 24 are provided in the first plate-shaped part 211 of the door limiting tube 2. Correspondingly, a process hole 216 is provided in the second plate-shaped part 212, and a second preset hole 215 is provided in the fourth plate-shaped part 214. When the door limiting tube 2 of the first structure is used in conjunction with the connecting rod 3 and the second pin 5, the second pin 5 should be inserted vertically downward into the mounting hole 22 of the first plate-shaped part 211.

[0087] In the second structure, the door limiting tube 2 is a rectangular tube as a whole, and a guide groove 21, a mounting hole 22, a first limiting hole 23 and a second limiting hole 24 are provided in the third plate-shaped part 213 of the door limiting tube 2. Correspondingly, a process hole 216 is provided in the second plate-shaped part 212, and a second preset hole 215 is provided in the fourth plate-shaped part 214. When the door limiting tube 2 of the second structure is used in conjunction with the connecting rod 3 and the second pin 5, the second pin 5 should be inserted vertically upward into the mounting hole 22 of the first plate-shaped part 211.

[0088] In the third structure, the door limiting tube 2 is a rectangular tube as a whole, and the first plate-shaped part 211 and the third plate-shaped part 213 of the door limiting tube 2 are respectively provided with a guide groove 21, a mounting hole 22, a first limiting hole 23 and a second limiting hole 24. Correspondingly, the second plate-shaped part 212 is provided with a process hole 216, and the fourth plate-shaped part 214 is provided with a second preset hole 215. When the door limiting tube 2 of the second structure is used in conjunction with the connecting rod 3 and the second pin 5, if the operator selects the mounting hole 22 located in the first plate-shaped part 211 to connect with the second pin 5 on the connecting rod 3, then, referring to the description of the first structure above, if the operator selects the mounting hole 22 located in the third plate-shaped part 213 to connect with the second pin 5 on the connecting rod 3, referring to the description of the second structure above, and at this time, the guide groove 21, the mounting hole 22, the first limiting hole 23 and the second limiting hole 24 of the first plate-shaped part 211 become observation windows for "observing the position of the second pin 5 located in the door limiting tube 2".

[0089] The structure of the gate limiting tube 2 formed by the "first plate-shaped portion 211 to the fourth plate-shaped portion 214 arranged in a counterclockwise direction" is similar to the structure of the gate limiting tube 2 formed by the "first plate-shaped portion 211 to the fourth plate-shaped portion 214 arranged in a clockwise direction" mentioned above, and will not be described again here.

[0090] Further, see Figure 6 In this embodiment, the door limiter 100 applied to energy storage cabinets or liquid-cooled cabinets has a connecting rod 3 comprising a first rod segment 33 and a second rod segment 34. The first rod segment 33 and the second rod segment 34 are integrally formed, and the included angle between the first rod segment 33 and the second rod segment 34 is an obtuse angle.

[0091] In some existing technologies, the rod-shaped component equivalent to the connecting rod 3 in this embodiment has a straight structure. When the cabinet door is opened relative to the cabinet and the opening angle of the cabinet door relative to the cabinet is too large, the rod-shaped component may interfere with the cabinet, causing the cabinet door to be unable to continue rotating.

[0092] In this embodiment, by setting the included angle between the first segment 33 and the second segment 34 of the connecting rod 3 to an obtuse angle, a spanning structure that crosses the cabinet 200 is formed at the connection of the first segment 33 and the second segment 34, which enables the cabinet door 300 to open at a larger angle relative to the cabinet 200.

[0093] Furthermore, in this embodiment, the door limiter 100 applied to the energy storage cabinet or liquid cooling cabinet has a door limit tube 2 at an angle of 90 degrees relative to the positioning bracket 1 when the second pin 5 is located in the first limiting hole 23.

[0094] When the second pin 5 is located in the second limiting hole 24, the angle between the door limiting tube 2 and the positioning bracket 1 is 135 degrees.

[0095] It should be understood that in other embodiments, other limiting holes may be provided so that the angle of the door limiting tube 2 relative to the positioning bracket 1 is limited to other angles, such as one of the angles between 90 degrees and 135 degrees, or one of the angles between 45 degrees and 90 degrees, or one of the angles between 135 degrees and 180 degrees, or simply set to 180 degrees.

[0096] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
