[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a portable switch cabinet door limiter, which includes a support component 100 and a telescopic component 200. The support component 100 can support and limit the cabinet door when it is opened, and the support length can be freely adjusted through the telescopic component 200 to make it suitable for cabinet doors with different opening and closing angles.

[0031] Specifically, the support assembly 100 includes a center block 101, a first support rod 102, a rotating ring 103, a second support rod 104, an adsorption member 105, a limiting gear 106, a pressing rod 107, a gear ring 108 and a limiting member 109. The first support rod 102 is fixed to one side of the center block 101, the rotating ring 103 is rotatably connected to the top of the center block 101, the second support rod 104 is fixed to one side of the rotating ring 103, the adsorption member 105 is arranged at the ends of the first support rod 102 and the second support rod 104, the limiting gear 106 is fixed to the bottom of the rotating ring 103, a first chamber S1 is opened in the center block 101, the pressing rod 107 slides in the first chamber S1, the gear ring 108 is fixed to the bottom end of the pressing rod 107 and cooperates with the limiting gear 106, and the limiting member 109 is arranged on the pressing rod 107.

[0032] The center block 101 and the rotating ring 103 are both circular and rotatably connected via a bearing. When the rotating ring 103 rotates on the center block 101, the angle between the first support rod 102 and the second support rod 104 can be adjusted, so that the limiter can be suitable for cabinet doors with different opening and closing angles. Two adsorption members 105 are provided, which are rotatably connected to the ends of the two support rods via hinges or fixed axes, so that they can adapt to different installation angles when supporting. One of them is fixed on the cabinet door, and the other can be fixed on a position such as a cabinet body that can provide stable support.

[0033] When the limiting gear 106 and the toothed ring 108 are meshed, the rotating ring 103 can be fixed so that it cannot rotate relative to the center block 101. When the two are separated, it can rotate. When the pressing rod 107 moves into the first chamber S1, it can drive the toothed ring 108 away from the limiting gear 106. The limiting member 109 limits the pressing rod 107 and the toothed ring 108, making it more convenient to use.

[0034] The telescopic assembly 200 is arranged in the first support rod 102, and includes a telescopic rod 201, a positioning member 202 and a limiting member 203. The telescopic rod 201 slides in the first support rod 102, the positioning member 202 is arranged between the first support rod 102 and the telescopic rod 201, and the limiting member 203 is arranged in the first support rod 102.

[0035] The telescopic rod 201 can extend the supporting length of the first support rod 102, so that the use range of the limiter is larger. The positioning member 202 is used to limit and fix the telescopic rod 201 so that it can be stably fixed at any length. The limiting member 203 cooperates with the toothed ring 108 and the limiting member 109 to make it more convenient to store.

[0036] Example 2

[0037] Reference Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the limiting member 109 includes a cross column 109a, a top plate 109b and a first spring 109c. The cross column 109a is fixed in the first chamber S1. The pressing rod 107 is provided with a cross slot K matching therewith. The top plate 109b is fixed to the top of the pressing rod 107. The first spring 109c is fixed to the bottom of the top plate 109b, and its bottom end is in contact with the rotating ring 103.

[0039] The cross column 109a slides in the cross groove K to limit the pressing rod 107 to prevent it from rotating during the up and down movement. The setting of the top plate 109b can facilitate the user to press the pressing rod 107 downward. The first spring 109c applies an upward thrust to the top plate 109b and the pressing rod 107, so that after the staff releases the top plate 109b, it can be reset faster, thereby driving the gear ring 108 to engage with the limiting gear 106 to fix the rotating ring 103.

[0040] The limiting member 109 also includes a movable block 109d, a connecting rod 109e, a limiting block 109f and a fixed block 109g. The movable block 109d is rotatably connected to the middle of the top plate 109b, the connecting rod 109e is fixed to the bottom of the movable block 109d, the limiting block 109f is fixed to the bottom end of the connecting rod 109e, and the fixed block 109g is fixed to the inner wall of the cross groove K and cooperates with the limiting block 109f.

[0041] The movable block 109d is rotatably connected to the middle part of the top plate 109b through a bearing. Two fixed blocks 109g are provided, which are symmetrically distributed on the inner wall of the cross groove K. When the staff presses the top plate 109b downward, the limit block 109f will move below the fixed block 109g. At this time, the staff can manually twist the movable block 109d to rotate the limit block 109f to contact the bottom of the fixed block 109g, thereby limiting the pressing rod 107 and the gear ring 108 so that they cannot be pushed to reset by the first spring 109c. At this time, the rotating ring 103 can be rotated at will, and the staff can rotate the second support rod 104 to fit with the first support rod 102, so as to facilitate the storage of the limiter after use.

[0042] The limiting member 109 further includes a protrusion 109h, which is fixed to one side of the movable block 109d, and an arc groove P cooperating with the protrusion 109h is formed on the top plate 109b.

[0043] The arc groove P is 90 degrees, and the protrusion 109h slides in the arc groove P to limit the movable block 109d, so that when it rotates to both ends, it corresponds to the fixed and released states respectively, avoiding excessive rotation angle when fixing is required.

[0044] A rectangular bar 109d-1 is fixed on the top of the movable block 109d, which is in a protruding shape, so that the staff can easily rotate the movable block 109d while pressing the pressing rod 107 downward.

[0045] Example 3

[0046] Reference Figures 1 to 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0047] Specifically, the positioning member 202 includes a movable rod 202a, a connecting plate 202b, a positioning rod 202c, a pressing plate 203d and a second spring 202e. The movable rod 202a slides on the first support rod 102, the connecting plate 202b is fixed to the bottom end of the movable rod 202a, the positioning rod 202c is fixed to both sides of the top of the connecting plate 202b, a rectangular groove Y is opened in the middle of the telescopic rod 201, and a positioning groove M matching the positioning rod 202c is opened at the bottom thereof, the pressing plate 203d is fixed to the top of the movable rod 202a, and the second spring 202e is fixed to the bottom of the pressing plate 203d, and its bottom end contacts the first support rod 102.

[0048] A plurality of positioning grooves M are provided on both sides of the inner top wall of the rectangular groove Y. The second spring 202e applies an upward thrust to the pressing plate 203d and the movable rod 202a, so that the two positioning rods 202c are correspondingly inserted into the positioning grooves M on both sides. At this time, the telescopic rod 201 can be fixed so that it cannot be extended or retracted. When its length needs to be adjusted, the pressing plate 203d can be pressed downward to disengage the positioning rod 202c from the positioning groove M, and the length of the telescopic rod 201 can be manually and freely adjusted.

[0049] The positioning member 202 also includes a stopper 202f, which is fixed to the end of the rectangular groove Y. A groove is provided on the top of the stopper 202f. When the telescopic rod 201 needs to be removed, the pressing plate 203d is first pressed downward to disengage the positioning rod 202c from the positioning groove M. Then the pressing plate 203d is manually rotated to make the connecting plate 202b parallel to the rectangular groove Y. At this time, the pressing plate 203d is released, and the pressing plate 203d and the movable rod 202a are pushed upward by the second spring 202e. Two through holes are provided on the first support rod 102. At this time, the positioning rod 202c will be located in the two through holes, and the telescopic rod 201 can be pulled out, and the connecting plate 202b will be disengaged from the groove, and the telescopic rod 201 can be removed.

[0050] The limiting member 203 includes a limiting block 203a, a push rod 203b and a fixing rod 203c. A through hole L is opened on the inner wall of the first chamber S1. The limiting block 203a slides in the through hole L. The push rod 203b is fixed to the bottom of one side of the limiting block 203a and cooperates with the limit block 109f. The fixing rod 203c is fixed to one side of the limiting block 203a and is located in the first support rod 102.

[0051] The fixed rod 203c is L-shaped and is located inside the first support rod 102. The top rod 203b is located inside the cross column 109a in the initial state and is parallel to the limit block 109f. When the limit block 109f is in contact with the bottom of the fixed block 109g, the top rod 203b is pushed in the direction of the limit block 109f, and the limit block 109f can be pushed to rotate by the top rod 203b to separate it from the fixed block 109g.

[0052] In the initial state, the limiting block 203a is located in the through hole L and below the gear ring 108. When the limiter needs to be stored, the staff presses the top plate 109b downward, and the limiting block 109f will move below the fixed block 109g. At this time, the staff manually twists the movable block 109d to rotate the limiting block 109f to contact the bottom of the fixed block 109g, thereby limiting the pressing rod 107 and the gear ring 108 so that they cannot be pushed back by the first spring 109c. At this time, the rotating ring 103 can be rotated at will, and the staff can rotate the second support rod 104 to fit with the first support rod 102, and at the same time fully extend the telescopic rod 201 into the first support rod 102, and push the fixed The rod 203c and the limiting block 203a move, and the top rod 203b moves toward the limit block 109f, and the limit block 109f is pushed to rotate by the top rod 203b to separate it from the fixed block 109g. At this time, the first spring 109c applies an upward thrust to the top plate 109b and the pressing rod 107 to quickly reset them, thereby driving the gear ring 108 to engage with the limit gear 106, fixing the rotating ring 103, and fixing the two support rods. At the same time, the limiting block 203a is partially located in the first chamber S1 and below the gear ring 108. The gear ring 108 is limited by the limiting block 203a to avoid the gear ring 108 accidentally separating from the limit gear 106 during storage and transportation, causing the two support rods to separate.

[0053] The limiting member 203 further includes a baffle 203d and a third spring 203e. The baffle 203d is fixed in the through hole L, and two ends of the third spring 203e are respectively fixed to the fixing rod 203c and the baffle 203d.

[0054] The baffle 203d is used to limit the limiting block 203a so that it can be located in the through hole L in the initial state. At the same time, the third spring 203e applies a force to the fixing rod 203c and the limiting block 203a to move toward the inside of the first support rod 102, so that the telescopic rod 201 can be reset more quickly when it extends from the inside of the first support rod 102.

[0055] The material of the adsorption member 105 is a magnet, which can be more conveniently and firmly fixed on the cabinet door and the cabinet body. This part can also adopt a suction cup or the like, and technical personnel in this field can set it as needed.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
