Description
Technical Field
[0001] The utility model relates to the technical field of emergency buttons, in particular to a novel emergency button. Background Art
[0002] As a crucial safety feature, emergency buttons are widely used in smart homes, outdoor equipment, public facilities, and industrial environments. Existing emergency buttons typically utilize either a push-button or pull-type trigger mechanism. Pull-type mechanisms utilize an exposed pull cord for rapid activation. To adapt to complex environments, these products often incorporate sealing rings or waterproof coatings at the housing joints, and static sealing components such as rubber grommets at the pull cord exit to enhance dust and water resistance.
[0003] However, the existing technology has obvious defects: conventional waterproof structures cannot effectively deal with the problem of sealing failure caused by the dynamic movement of the pull cord - when the pull cord is repeatedly pulled, the rubber wire sleeve is easily worn and deformed to form a water seepage gap, and the single-point seal in a static state is difficult to completely block water vapor penetration; at the same time, long-term friction between the pull cord and the shell will accelerate the aging of the seal, causing the button to lose reliability in a humid environment and posing a risk of circuit short circuit.
[0004] Therefore, the inventor urgently needs a new emergency button to solve the above problems. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the present invention provides a new emergency button, which aims to solve the problem of waterproof failure caused by wear of the seal when the pull rope of the emergency button moves dynamically in the prior art.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a new emergency button, including a front cover assembly and a back cover assembly, a sliding pulling structure is provided in the front cover assembly, the sliding pulling structure includes a sliding frame, a guide frame, a guide groove block integrally formed between the guide frame and the edge of the front cover assembly, and a pull rope assembly, the pull rope assembly includes a sliding block slidably fitted in the sliding frame, a return spring abutting between the sliding block and the inner wall of the sliding frame close to the guide frame, a pull rope fixed on the sliding block, and a plurality of steel balls fixed on the pull rope at intervals, the pull rope passes through the return spring, the hollow guide column and the guide groove block in the guide frame in turn and extends to the outside, the inner diameter of the hollow guide column is adapted to the outer diameter of each steel ball, and when the pull rope is in a tightened or loosened state, at least one steel ball is embedded in the hollow guide column to achieve dynamic sealing.
[0007] Based on the above, the beneficial effect of a new emergency button is to solve the problem of waterproof failure caused by seal wear during dynamic movement of the pull cord in the existing technology; it is mainly reflected in:
[0008] 1. This utility model uses a plurality of steel balls fixed at intervals on the pull rope to cooperate with the hollow guide column. The steel balls roll in contact in the guide groove block. This achieves sealing by utilizing the rolling contact between the hard steel balls and the inner wall of the hollow guide column during the dynamic movement of the pull rope, fundamentally avoiding the problem of waterproof failure caused by repeated friction of radial friction seals.
[0009] 2. The utility model adopts a design in which the inner diameter of the hollow guide column is adapted to the outer diameter of each steel ball. Therefore, no matter whether the rope is in a tightened or loose state, at least one steel ball is embedded in the hollow guide column. The steel ball tightly fills the inner hole of the hollow guide column, forming an effective physical blocking barrier at the key exit of the rope movement path, isolating the infiltration path of external water vapor and liquid.
[0010] 3. The utility model adopts a path design in which the pull rope passes through the reset spring, the hollow guide column of the guide frame and the guide groove block in sequence. The reset spring continuously provides tension to reset the sliding block and the pull rope, ensuring that when the pull rope is not pulled, the steel ball chain maintains a preset tensioning position in the hollow guide column and the steel balls in the hollow guide column are tightly embedded; when the pull rope is pulled and is in a tensioned state, the steel ball chain moves sequentially in the hollow guide column, and there is always at least one steel ball occupying the sealing position, thereby achieving that in all working states of the pull rope, the channel of the hollow guide column is reliably sealed by the steel balls to form a dynamic waterproof effect, solving the problem that static single-point sealing is difficult to block water vapor penetration.
[0011] Furthermore, a steel ball on the pull rope closest to the sliding block is embedded in a steel ball embedding groove opened at the end of the sliding block, and a pull rope adapter groove for the pull rope to pass through is opened on the side of the steel ball embedding groove close to the guide frame.
[0012] Based on the above, the beneficial effect of the steel ball embedding groove is that a specific groove structure is formed at the end of the sliding block, and the steel ball closest to the sliding block is embedded and confined in the groove, thereby realizing mechanical interlocking of the steel ball and the sliding block, ensuring that the pull rope directly transmits the pulling force to the sliding block through the steel ball during the pulling process, avoiding the risk of falling off caused by stress concentration at the pull rope joint; the beneficial effect of the pull rope adapter groove is that a through channel is opened on the side of the steel ball embedding groove close to the guide frame, for the pull rope to pass through the sliding block in a straight line path, so that the pull rope remains in a naturally stretched state when the steel ball is fully embedded in the steel ball embedding groove, eliminating the bending and wear of the pull rope at the connection of the sliding block, and ensuring the reliability of the pull rope during long-term use.
[0013] Furthermore, sliding grooves are provided on both sides of the sliding frame, and sliding block limiting protrusions adapted to the sliding grooves are provided at both ends of the sliding block, and the sliding limiting protrusions are slidably limited in the sliding grooves.
[0014] Based on the above, the beneficial effect of the sliding groove is that it is opened on both side walls of the sliding frame, providing a precise guide path for the slider limiting protrusion of the sliding block, so that the sliding block can only slide back and forth along the preset straight line direction in the sliding frame, avoiding distortion or jamming of the return spring caused by movement deviation.
[0015] Furthermore, the front cover assembly includes a front cover body and an SOS embedded plate. The outer periphery of the front cover body is provided with an embedded groove, and the SOS embedded plate is embedded in the front cover body through the embedded groove.
[0016] Based on the above, the beneficial effect of the embedded groove is that the continuous annular groove body is formed by processing the outer peripheral edge of the front cover body, which provides circumferential positioning and bearing base for the SOS embedded plate, and realizes that the SOS embedded plate is accurately embedded in the surface of the front cover body through physical snap-fitting, avoiding the risk of falling off and aging failure caused by the use of adhesives; the beneficial effect of the SOS embedded plate is that it is an identification module independent of the front cover body, and detachable assembly is achieved through the embedded groove, which realizes the rapid replacement or customized design of the emergency sign, meets the visual warning needs of different application scenarios, and is convenient for separate disassembly, cleaning or replacement during maintenance.
[0017] Furthermore, a circuit board is arranged between the front cover body and the back cover assembly, and a plurality of internally threaded mounting posts are arranged around the inner side of the front cover body. Mounting holes corresponding to the positions of the internally threaded mounting posts are opened around the circuit board, and the circuit board is sleeved on the internally threaded mounting posts through the mounting holes.
[0018] Based on the above, the beneficial effect of the internal threaded mounting column is that it is vertically arranged around the inner side of the front cover body to form a rigid support body with internal threads, which bears the fastening force of the back cover assembly through threaded connection, thereby realizing the synchronous positioning and fixation of the circuit board and the back cover assembly, eliminating the cumulative assembly error caused by traditional step-by-step installation; the beneficial effect of the mounting hole is that it cooperates with the outer periphery of the internal threaded mounting column to realize the precise positioning of the circuit board in the horizontal direction and the suspended support in the vertical direction, avoiding damage to components caused by direct contact of the bottom surface of the circuit board with the front cover body.
[0019] Furthermore, the back cover assembly includes a rear cover body and a waterproof sticker. The rear cover body is provided with a plurality of through holes corresponding to the positions of the internally threaded mounting posts respectively. The rear cover body is threadedly connected to the internally threaded mounting posts by screws passing through the through holes, thereby fixing the rear cover body and the circuit board to the front cover body. A waterproof sticker groove is provided on the outer end surface of the rear cover body. The waterproof sticker is pasted in the waterproof sticker groove, and the waterproof sticker covers the plurality of through holes.
[0020] Based on the above, the beneficial effect of the waterproof sticker groove is that a recessed area is formed on the outer end surface of the back cover body, providing a precise positioning reference and accommodation space for the waterproof sticker, thereby achieving smooth pasting of the waterproof sticker and avoiding edge warping or falling off caused by uneven surface; the beneficial effect of the waterproof sticker is that it is pasted in the waterproof sticker groove and completely covers the through hole. Through its own waterproof performance and close fit with the waterproof sticker groove, multiple sealing protections are achieved for the screw mounting holes, effectively blocking external water vapor from penetrating into the internal circuit board area from the through hole.
[0021] Furthermore, a battery installation compartment is provided on the end surface of the circuit board close to the front cover body and away from the side of the sliding pulling structure, and a battery installation port is provided on one end of the battery installation compartment close to the adjacent internal threaded installation column.
[0022] Furthermore, a curved surface is provided on one side of the battery installation port close to the adjacent internally threaded installation column, and the curved surface is adapted to the outer wall of the adjacent internally threaded installation column to prevent the battery from falling out.
[0023] Based on the above, the beneficial effect of the arc surface is that it matches the outer wall of the internal thread mounting post, so that after the battery is installed, the side of the internal thread mounting post forms a fitting contact with the arc surface, preventing the battery from accidentally falling out.
[0024] Furthermore, the hollow guide column is a silicone piece.

The inner diameter of the hollow guide column 421 is adapted to the outer diameter of each steel ball 444, and when the pull rope 443 is in a tightened or loosened state, two steel balls 444 are embedded in the hollow guide column 421 to achieve dynamic sealing.
[0032] A steel ball 444 on the pull rope 443 closest to the sliding block 441 is embedded in a steel ball embedding groove 4411 opened at the end of the sliding block 441 . A pull rope adapter groove 4412 for the pull rope 443 to pass through is opened on the side of the steel ball embedding groove 4411 close to the guide frame 42 .
[0033] Sliding grooves 411 are formed on both sides of the sliding frame 41 , and sliding block 441 has slider limiting protrusions 4413 adapted to the sliding grooves 411 at both ends. The slider limiting protrusions 4413 are slidably limited in the sliding grooves 411 .
[0034] The front cover assembly 1 includes a front cover body 11 and an SOS embedded plate 12 . An embedded groove 111 is provided on the outer periphery of the front cover body 11 , and the SOS embedded plate 12 is embedded in the front cover body 11 through the embedded groove 111 .
[0035] A circuit board 3 is arranged between the front cover body 11 and the back cover assembly 2. A plurality of internally threaded mounting posts 112 are arranged around the inner side of the front cover body 11. Mounting holes 31 corresponding to the positions of the internally threaded mounting posts 112 are opened around the circuit board 3. The circuit board 3 is sleeved on the internally threaded mounting posts 112 through the mounting holes 31.
[0036] The back cover assembly 2 includes a rear cover body 21 and a waterproof sticker 22. The rear cover body 21 is provided with a plurality of through holes 211 corresponding to the positions of the internal threaded mounting columns 112. The rear cover body 21 is threadedly connected to the internal threaded mounting columns 112 by screws passing through the through holes 211, thereby fixing the rear cover body 21 and the circuit board 3 on the front cover body 11. The outer end surface of the rear cover body 21 is provided with a waterproof sticker groove 212. The waterproof sticker 22 is pasted in the waterproof sticker groove 212, and the waterproof sticker 22 covers the plurality of through holes 211.
[0037] A battery installation compartment 32 is provided on the end surface of the circuit board 3 close to the front cover body 11 and away from the side of the sliding pulling structure 4. A battery installation port 321 is provided on one end of the battery installation compartment 32 close to the adjacent internal thread installation column 112.
[0038] A curved surface 322 is provided on one side of the battery installation opening 321 close to the adjacent internally threaded installation column 112 .

[0039] The hollow guide column 421 is a silicone member.
[0040] In summary, the specific implementation methods of the present invention are as follows:
[0041] When the user needs to trigger the emergency alarm, he pulls the pull rope 443 extending to the outside, and the pull rope 443 drives several steel balls 444 fixed thereon to move synchronously. At this time, the first steel ball 444 closest to the sliding block 441 drives the sliding block 441 to slide in the sliding frame 41 through the steel ball embedding groove 4411. The slider limit protrusions 4413 at both ends of the sliding block 441 move linearly along the sliding grooves 411 on both sides of the sliding frame 41. At the same time, the sliding block 441 compresses the return spring 442 between it and the inner wall of the sliding frame 41. During the movement of the pull rope 443, several steel balls 444 roll sequentially in the hollow guide column 421. Since the inner diameter of the hollow guide column 421 is precisely adapted to the outer diameter of a single steel ball 444, no matter whether the pull rope 443 is in a pulling state or a stationary state, there is always at least one steel ball 444 embedded in the hollow guide column 421 to form a dynamic sealing barrier;
[0042] When the pull rope 443 is released, the compressed return spring 442 pushes the sliding block 441 to return to its original position. The sliding block 441 drives the first steel ball 444 to move in the opposite direction through the steel ball embedding groove 4411, thereby pulling the pull rope 443 and the steel ball 444 chain back as a whole. At this time, the slider limit protrusion 4413 slides back to the initial position along the sliding groove 411, and the steel ball 444 remains sealed in the hollow guide column 421.
[0043] The circuit board 3 is positioned by being sleeved on the internal threaded mounting post 112 of the front cover body 11 through the mounting hole 31. The rear cover body 21 is locked with the internal threaded mounting post 112 by screws passing through the through hole 211. The waterproof sticker 22 completely covers the through hole 211 area and is pasted in the waterproof sticker groove 212 to form a secondary waterproof barrier. After the battery is installed in the battery mounting compartment 32 through the battery mounting port 321, its side is limited by the arc surface 322 and the outer wall of the adjacent internal threaded mounting post 112 to prevent it from falling off due to vibration.
[0044] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or replacements of the present invention made by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
