In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0032] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0034] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0036] As mentioned above, the connection between the switch line and the external line of the traditional speed limiter lacks a protective structure. Specifically, the switch wiring of the traditional speed limiter has not been scientifically designed. The switch line can only pass through the gap between the outer cover and the switch bracket, and the switch line passes through the outer cover and then connects to the external line. In this way, the interface of the switch line is directly exposed outside the outer cover, which is not only unsightly, but also easily polluted by the outside, which can easily lead to failure of the connection between the switch line and the external line, thereby causing the speed limiter to fail to work, thereby increasing the risk of elevator accidents.

[0037] Based on this, an embodiment of the present application provides a speed limiter mounting bracket, referring to Figures 1 and 2, the speed limiter mounting bracket of one embodiment includes an outer cover 30, a first bracket 10 and a second bracket 20, wherein the outer cover 30 is provided with a cavity 33 for accommodating a speed limiter body 52 and a speed limiter switch 51 and a wire inlet 31 connected to the cavity 33, the first bracket 10 is used to connect the speed limiter body 52 and the speed limiter switch 51 so that the speed limiter body 52 and the speed limiter switch 51 are relatively fixed, the second bracket 20 is connected to the first bracket 10 and covers the wire inlet 31, the second bracket 20 is provided with a wire threading hole 21 for allowing an external wire 61 to pass through the accommodating cavity, and the second bracket 20 is used to fix the external wire 61.

[0038] Specifically, in the above-mentioned speed limiter mounting frame, the speed limiter body 52 and the speed limiter switch 51 are fixed by the first bracket 10, and the wire inlet 31 is opened on the outer cover 30, and the second bracket 20 is connected to the first bracket 10 and is provided with a threading hole 21 connected to the wire inlet 31, so that the external wire 61 can pass through the threading hole 21 and the wire inlet 31 to penetrate into the cavity 33 of the outer cover 30, and can be connected with the switch wire 511 of the speed limiter switch 51 in the cavity 33, so that the connection between the switch wire 511 and the external wire 61 can be hidden in the cavity 33 of the outer cover 30, avoiding the connection between the switch wire 511 and the external wire 61 from being polluted or corroded by the outside world and failing. At the same time, the second bracket 20 can cover the wire inlet 31, so as to seal the wire inlet 31 of the outer cover 30, further improving the protection effect of the connection between the switch wire 511 and the external wire 61, improving the rationality and reliability of the wiring of the speed limiter switch 51, and thus improving the safety of the elevator operation.

[0039] Referring to FIG. 3 , optionally, in one embodiment, the first bracket 10 includes a first mounting plate 11, a second mounting plate 13 and a folded edge 12, the first mounting plate 11 and the second mounting plate 13 are respectively connected to the two sides of the folded edge 12, and the first mounting plate 11 and the second mounting plate 13 extend in opposite directions, that is, the first bracket 10 is a "Z"-shaped structure as a whole. In conjunction with FIG. 4 and FIG. 5 , there is a gap between the first mounting plate 11 and the outer cover 30, the first mounting plate 11 is used to connect with the speed limiter switch 51, and the second mounting plate 13 is used to connect with the speed limiter body 52. ​​Specifically, in one embodiment, the first mounting plate 11 is connected to the limiter switch by bolts, and the second mounting plate 13 is connected to the limiter body by bolts.

[0040] Specifically, the traditional switch bracket is in an "N"-shaped structure as a whole. When installing the speed limiter switch 51, the two side plates of the switch bracket will block each other, making it inconvenient to install and adjust the speed limiter switch 51. The first bracket 10 of an embodiment of the present application is in a "Z"-shaped structure as a whole. The first mounting plate 11 and the second mounting plate 13 extend in opposite directions respectively, so that when the speed limiter switch 51 is installed on the first mounting plate 11, the second mounting plate 13 will not block the installation operation, which makes it easier to install and adjust the position of the speed limiter switch 51. At the same time, there is a gap between the first mounting plate 11 and the outer cover 30, so as to reserve wiring space for the connection between the switch line 511 of the speed limiter and the external line 61, making the wiring of the speed limiter more reasonable.

[0041] Referring to Fig. 2, optionally, in one embodiment, the outer cover 30 is further provided with an avoidance opening 32, and the avoidance opening 32 is communicated with the inlet opening 31. In conjunction with Fig. 4, the second mounting plate 13 is arranged in the avoidance opening 32. Specifically, when assembling the speed limiter mounting frame, the second bracket 20 is first fixed on the second mounting plate 13, and then the speed limiter switch 51 is fixed through the first mounting plate 11, and then the first bracket 10 is fixed on the speed limiter body 52 through the second mounting plate 13, and then the external line 61 is passed through the threading hole 21 and connected with the switch line 511 of the speed limiter switch 51, and finally the outer cover 30 is set outside the limiter body and the limiter switch, and the second bracket 20 covers the inlet opening 31, and the second mounting plate 13 is plugged into the avoidance opening 32 of the outer cover 30, so as to realize the preliminary fixation of the outer cover 30, and finally the outer cover 30 is fixed to the speed limiter body 52 by screws or bolts.

[0042] Further, referring to FIG. 4 , the second bracket 20 is connected to the second mounting plate 13, and the second bracket 20 is located on the side of the outer cover 30 away from the cavity 33, that is, the second bracket 20 is located outside the outer cover 30, so that the external line 61 can be better fixed without occupying the cavity 33 of the outer cover 30, so that the internal space of the outer cover 30 is more abundant, and it is also convenient for the second bracket 20 to connect other components, such as for connecting the fixing sleeve 40.

[0043] Specifically, referring to FIG. 3 and FIG. 4 , the speed limiter mounting frame further includes a fixing sleeve 40, which is connected to the second bracket 20, and is provided with a through hole 41 communicating with the threading hole 21, and the through hole 41 is used for passing the external line 61. The fixing sleeve 40 is used to connect the hose 62 located outside the external line 61. Specifically, the hose 62 is sleeved outside the external line 61 for protecting the external line 61, and is connected to the hose 62 by the fixing sleeve 40, so that the hose 62 can be fixed, thereby fixing the external line.

[0044] Optionally, in one embodiment, the fixing sleeve 40 is threadedly connected to the hose 62. Specifically, the through hole 41 is a threaded hole, and the hose 62 is provided with an external thread, and the hose 62 can be fixed by threading the hose 62 with the through hole 41. It is worth noting that, in another embodiment, the hose 62 and the through hole 41 can also be interference fit or snap fit, which can also achieve the fixation of the hose 62.

[0045] Referring to FIG. 3 , optionally, in one embodiment, the first mounting plate 11 is provided with a waist-shaped hole 101, and the long axis direction of the waist-shaped hole 101 is the same as the extension direction of the first mounting plate 11. The “long axis direction of the waist-shaped hole 101” refers to the direction in which the length of the waist-shaped hole 101 is located. For example, in one embodiment, the extension direction of the first mounting plate 11 is the height direction of the elevator, and the long axis direction of the waist-shaped hole 101 is also the height direction of the elevator. Further, the waist-shaped hole 101 is used to penetrate a threaded connector, and the threaded connector is connected to the speed limiter switch 51. In one embodiment, the threaded connector is a bolt. By providing the waist-shaped hole 101 on the first mounting plate 11, and then by penetrating the threaded connector in the waist-shaped hole 101 and connecting it to the speed limiter switch 51, the speed limiter switch 51 can be fixed on the first mounting plate 11, and by adjusting the position of the threaded connector in the waist-shaped hole 101 along the long axis direction, the position of the speed limiter switch 51 can be adjusted to adapt to different installation scenarios, thereby improving applicability.

[0046] Furthermore, there are multiple waist-shaped holes 101, and each waist-shaped hole 101 is arranged at intervals along a direction perpendicular to the extension direction of the first mounting plate 11. For example, in this embodiment, the first mounting plate 11 is provided with two waist-shaped holes 101, and the two waist-shaped holes 101 are arranged at intervals along the width direction of the first mounting plate 11, and each waist-shaped hole 101 is penetrated by a threaded connector, and all the threaded connectors are connected to the speed limiter switch 51, so that the fixing effect of the speed limiter switch 51 can be improved.

[0047] An embodiment of the present application also provides a speed limiter. Specifically, the speed limiter of one embodiment includes a speed limiter body 52, a speed limiter switch 51, a switch wire 511 and a speed limiter mounting frame of any of the above embodiments. The speed limiter body 52 is electrically connected to the speed limiter switch 51, and the speed limiter body 52 and the speed limiter switch 51 are both connected to the first bracket 10. One end of the switch wire 511 is connected to the speed limiter switch 51, and the other end is connected to the external wire 61 that enters the cavity 33 through the wire threading hole 21 and the wire inlet 31.

[0048] Furthermore, another embodiment of the present application provides an elevator, comprising the speed limiter of any of the above embodiments.

[0049] Specifically, in the above-mentioned speed limiter and elevator, the speed limiter body 52 and the speed limiter switch 51 are fixed by the first bracket 10, and the wire inlet 31 is opened on the outer cover 30, and the second bracket 20 is connected to the first bracket 10 and is provided with a threading hole 21 connected to the wire inlet 31, so that the external wire 61 can pass through the threading hole 21 and the wire inlet 31 to penetrate into the cavity 33 of the outer cover 30, and can be connected with the switch wire 511 of the speed limiter switch 51 in the cavity 33, so that the connection between the switch wire 511 and the external wire 61 can be hidden in the cavity 33 of the outer cover 30, avoiding the connection between the switch wire 511 and the external wire 61 from being polluted or corroded by the outside world and failing. At the same time, the second bracket 20 can cover the wire inlet 31, so as to seal the wire inlet 31 of the outer cover 30, further improving the protection effect of the connection between the switch wire 511 and the external wire 61, improving the rationality and reliability of the wiring of the speed limiter switch 51, and thus improving the safety of the elevator operation.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
