Description

Technical Field

[0001] This utility model relates to the field of rail transit equipment technology, and in particular to an emergency stop button mounting bracket and an emergency stop device. Background Technology

[0002] An emergency stop button is a type of rail transit signaling equipment used to notify trains to stop in emergency situations. It typically includes a wiring box and a panel attached to one side of the box. During installation, the wiring box and panel need to be connected to a concrete wall and an enamel-lined steel plate, respectively. Specifically, the dimensions of the emergency stop button panel are provided to the enamel-lined steel plate manufacturer, who then pre-drills corresponding mounting holes and installs protective conduits on the steel plate, as well as laying the signal cable. After the enamel-lined steel plate is installed, the wiring box portion of the emergency stop button is passed through the pre-drilled mounting holes. The installation position of the wiring box is marked on the concrete wall, and expansion bolts are installed at the corresponding locations. Finally, the signal cable is stripped and threaded into the emergency stop button, and the wiring box is fixed to the wall using expansion bolts, completing the signal cable wiring and ensuring proper protection of the finished product.

[0003] Normally, after the emergency stop button is installed, its panel will fit tightly against the enamel steel plate, and the wiring box will be embedded in the pre-embedded mounting hole of the enamel steel plate. However, in some installation scenarios, such as on the exterior wall of the triangular machine room of an escalator, the hole behind the emergency stop button may be suspended in the air. When the clearance between the enamel steel plate and the wall is insufficient, the depth of the pre-embedded mounting hole is not deep enough to accommodate the entire wiring box, resulting in partial exposure of the wiring box. This is not only detrimental to the aesthetics of the product but also increases the risk of the wiring box becoming loose, posing certain construction quality hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the technical problems in the prior art, such as the emergency stop button being prone to being suspended in the hole at the triangular machine room, and when the clearance between the enamel steel plate and the wall is insufficient, some wiring boxes will be exposed, which increases the risk of the wiring boxes becoming loose. The present invention provides an emergency stop button mounting bracket and an emergency stop device.

[0005] In a first aspect, the present invention provides an emergency stop button mounting bracket, comprising:

[0006] A fixed bracket is provided with a first mounting surface and a second mounting surface spaced apart along a first direction; a connecting through hole is provided on the first mounting surface for connecting an emergency stop button; and an oblong hole is provided on the second mounting surface for connecting to a wall.

[0007] The outer frame is fitted onto the end of the fixed bracket near the first mounting surface, and the position of the outer frame relative to the fixed bracket along the first direction is adjustable.

[0008] When the emergency stop button mounting bracket of this solution is used for installing emergency stop buttons, the second mounting surface of the bracket can be fixed to the wall first, and then the emergency stop button can be connected to the first mounting surface of the bracket, and the cable wiring of the emergency stop button can be carried out. After the cable wiring of the emergency stop button is completed, the outer frame is slid along the first direction toward the direction where the emergency stop button panel is located until the side of the outer frame away from the second mounting surface abuts against the panel. Then the panel, the outer frame, and the first mounting surface can form a protective chamber, protecting the wiring box of the emergency stop button in the protective chamber. The thickness of the protective chamber is determined by the dimension of the outer frame along the first direction, and is not affected by the clearance between the enamel steel plate and the wall. This avoids the situation where the wiring box of the emergency stop button is partially exposed due to insufficient clearance between the enamel steel plate and the wall, which would increase the risk of loosening.

[0009] Meanwhile, the position of the outer frame relative to the fixed bracket is adjustable, which makes the thickness of the protective chamber along the first direction adjustable. This allows it to adapt to various emergency stop buttons with different thicknesses, as well as installation scenarios with different wall surfaces and enamel steel plate spacings, making the solution more versatile.

[0010] Furthermore, during the installation of the emergency stop button, the holes behind it are fixed, while the actual installation situation is complex and varied. Sometimes, the connecting bolts behind the emergency stop button may interfere with or be suspended from the wall structure. Therefore, this solution also uses oblong holes on the second mounting surface used for connection with the wall. On the one hand, this allows workers to flexibly adjust the position of the connecting bolts along the length of the oblong hole according to the actual situation, thereby avoiding interference or suspension between the connecting bolts and the wall structure, and ensuring reliable connection between the fixed bracket and the wall. On the other hand, it also allows workers to insert at least two different lengths of connecting bolts into the oblong hole. By varying the length of the connecting bolts along the length of the oblong hole, the distance from each point on the curved wall to the second mounting surface can be adapted, thus ensuring that the fixed bracket of this solution can be firmly fixed to the curved wall, further enhancing the versatility of this solution.

[0011] Preferably, the fixing bracket is a square frame component, with openings at both ends along the second direction, which is perpendicular to the first direction; the shape and size of the outer frame match the shape and size of the fixing bracket.

[0012] The fixed bracket of this solution adopts a square frame component. On the one hand, it makes it convenient for workers to insert threaded connectors into the connecting through holes or oblong holes from the two openings of the square frame component, thereby improving the installation efficiency of the emergency stop button. On the other hand, the regular shape of the square frame component also helps to reduce the manufacturing difficulty and cost of the fixed bracket.

[0013] Preferably, the number of waist-shaped holes is at least two, the length of the waist-shaped holes is set along the third direction, the waist-shaped holes are distributed at intervals along the fourth direction, and the first direction, the third direction and the fourth direction are perpendicular to each other.

[0014] This solution can improve the reliability of the connection between the fixing bracket and the wall through at least two oblong holes.

[0015] Preferably, there is an angle between the second direction and the third direction, and there is also an angle between the second direction and the fourth direction.

[0016] The wall at the triangular machine room of the escalator has a sloping edge. When the square frame fixing bracket is connected to the wall, the connecting bolts are prone to being suspended at the sloping edge (the corner of the second mounting surface). Therefore, this solution sets the third and fourth directions at an angle relative to the second direction, so that the oblong hole can avoid the corner of the second mounting surface, thereby preventing the connecting bolts in the oblong hole from being suspended at the sloping edge of the wall of the triangular machine room, and thus better adapting to the triangular machine room.

[0017] Preferably, the number of connecting through holes is at least four, and the connecting through holes are distributed at intervals along the third and fourth directions.

[0018] This design arranges the connecting through holes in a checkerboard pattern on the first mounting surface. This arrangement is compatible with most existing emergency stop buttons and has good versatility.

[0019] Preferably, each connecting through hole is symmetrically distributed on both sides of the first mounting surface along the third or fourth direction; each oblong hole is symmetrically distributed on both sides of the second mounting surface along the third or fourth direction.

[0020] This design arranges the connecting through holes and the oblong holes symmetrically on both sides of the first and second mounting surfaces, which helps to maintain the force balance of the force-bearing system composed of the emergency stop button and the fixed bracket, thereby avoiding excessive local stress.

[0021] Preferably, at least two connecting bolts are connected in the oblong hole, and the connecting bolts have at least two different lengths.

[0022] When the wall surface is curved, the distance from each point on the wall surface to the second mounting surface will change. Therefore, this solution connects at least two types of connecting bolts of different lengths in the oblong hole to adapt to the change in distance from each point on the wall surface to the second mounting surface, thereby ensuring a reliable connection between the fixed bracket and the curved wall surface.

[0023] Preferably, the edge of the outer frame away from the second mounting surface is provided with a flange structure, and the flange structure extends toward the center of the outer frame.

[0024] This solution can increase the contact area between the outer frame and the panel.

[0025] Preferably, the length of the outer frame along the first direction is greater than the corresponding length of the fixed bracket.

[0026] This solution can avoid the situation where the outer frame is not long enough along the first direction, causing one end of the outer frame to slide towards the panel and then separate from the fixed bracket after it comes into contact with the panel, thus weakening the protection effect of this solution on the wiring box.

[0027] In a second aspect, the present invention provides an emergency stop device, including an emergency stop button, and also includes an emergency stop button mounting bracket of the present invention, wherein the emergency stop button is connected to a first mounting surface of the fixed bracket.

[0028] The emergency stop device of this solution connects the emergency stop button to the emergency stop button mounting bracket of this utility model. During installation, the emergency stop button can be fixed to the wall by the fixing bracket, and the wiring box of the emergency stop button is protected by the outer frame. This not only avoids the connecting bolts being suspended in the air, but also avoids the wiring box being partially exposed. It also allows the emergency stop button to be installed on curved walls, resulting in better construction quality and lower construction quality risks.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. This utility model provides an emergency stop button mounting bracket. The emergency stop button is fixed to the wall by the bracket and the wiring box of the emergency stop button is protected by the outer frame. This not only avoids the connecting bolts being suspended, but also avoids the wiring box being partially exposed. It also allows the emergency stop button to be installed on curved walls, resulting in better construction quality and lower construction quality risks.

[0031] 2. This utility model provides an emergency stop device. By fixing the emergency stop button to the wall using the emergency stop button mounting bracket of this utility model, the problems of suspended connecting bolts, exposed wiring boxes, and unreliable connections to curved walls can be avoided.

[0046] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0047] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use.

[0052] Example 1

[0053] like Figures 1 to 9 As shown, an emergency stop button mounting bracket includes a fixed bracket 1 and an outer frame 2. The fixed bracket 1 has a first mounting surface 11 and a second mounting surface 12 spaced apart along a first direction. The first mounting surface 11 has a connecting through hole 110 for connecting an emergency stop button 4. The second mounting surface 12 has an oblong hole 120 for connecting a wall surface 5. The outer frame 2 is fitted onto the end of the fixed bracket 1 near the first mounting surface 11, and the outer frame 2 can slide relative to the fixed bracket 1 along the first direction.

[0054] It is important to note that, in Figures 3 to 4 and Figures 7 to 8 Arrows are used to identify the various directions in this embodiment, where arrow X represents the first direction, arrow Y1 represents the second direction, arrow Y2 represents the third direction, and arrow Y3 represents the fourth direction; arrow Y represents the direction perpendicular to the first direction, which lies in the same plane as the second, third, and fourth directions.

[0055] In optional implementations, such as Figures 1 to 2 and Figures 5 to 7 As shown, the fixed bracket 1 is a square frame component with openings at both ends along the second direction, which is perpendicular to the first direction. The shape and size of the outer frame 2 match the shape and size of the fixed bracket 1, i.e., the outer frame 2 is also a square frame component, and the inner side of the outer frame 2 is clearance-fitted with the outer side of the fixed bracket 1, so that the outer frame 2 can be fitted onto the fixed bracket 1 and slide relative to the fixed bracket 1. The outer frame 2 has openings at both ends along the first square shape, one end of which is used to fit the fixed bracket 1, and the other end is used to connect the emergency stop button 4.

[0056] In an optional embodiment, the number of waist-shaped holes 120 is at least two, the length of the waist-shaped holes 120 is set along a third direction, and the waist-shaped holes 120 are spaced apart along a fourth direction, with the first direction, the third direction and the fourth direction being perpendicular to each other.

[0057] In an optional embodiment, the number of waist-shaped holes 120 is at least three, so that even if one of the waist-shaped holes 120 interferes with or is suspended from the wall 5 structure, at least two waist-shaped holes 120 can still maintain a reliable connection between the fixed bracket 1 and the wall 5.

[0058] In an optional implementation, there is an angle between the second direction and the third direction, and also an angle between the second direction and the fourth direction. The specific size of the angle can be matched with the tilt angle of the hypotenuse of the triangular machine room; for example... Figure 9 As shown, if the tilt angle of the hypotenuse of the triangular equipment room is 45° to the left, the included angle between the second and third directions, as well as the included angle between the second and fourth directions, can be set to 45°, so that the distribution square of the waist-shaped hole 120 is parallel to the hypotenuse of the triangular equipment room; in particular, if the tilt direction of the hypotenuse of the triangular equipment room changes to 45° to the right, it is not necessary to replace the new fixed bracket 1, but only to rotate the fixed bracket 1 by 90° for normal use.

[0059] In an optional embodiment, the number of connecting through holes 110 is at least four, and the connecting through holes 110 are distributed at intervals along the third and fourth directions to form a checkerboard array.

[0060] In an optional embodiment, each connecting through hole 110 is symmetrically distributed on both sides of the first mounting surface 11 along a third or fourth direction; each oblong hole 120 is symmetrically distributed on both sides of the second mounting surface 12 along a third or fourth direction. For example Figure 3 and Figure 4 As shown, the connecting through hole 110 is symmetrically arranged about the diagonal of the first mounting surface 11, and the waist-shaped hole 120 is symmetrically arranged about the diagonal of the second mounting surface 12.

[0061] In an optional embodiment, at least two connecting bolts 3 are connected to the oblong hole 120, and the connecting bolts 3 have at least two different lengths. For example Figure 8 As shown, the fixing bracket 1 can be connected to the curved wall surface 5 using two connecting bolts 3, one long and one short. It should be noted that there must be at least two connecting bolts 3, which can be all installed in one oblong hole 120 or distributed in at least two oblong holes 120.

[0062] In optional implementations, such as Figure 3 and Figure 5 As shown, the outer frame 2 has a flange structure 21 on the edge of the end away from the second mounting surface 12, and the flange structure 21 extends toward the center of the outer frame 2.

[0063] In an optional embodiment, the length of the outer frame 2 along the first direction is greater than the corresponding length of the fixed bracket 1.

[0064] Example 2

[0065] An emergency stop device includes an emergency stop button 4 and an emergency stop button mounting bracket as described in Embodiment 1. The emergency stop button 4 is connected to the first mounting surface 11 of the fixed bracket 1, and the panel 41 abuts against the side of the outer frame 2 away from the second mounting surface 12, thereby enclosing the wiring box 42 in the protective cavity formed by the panel 41, the outer frame 2 and the first mounting surface 11.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
