Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to a tooling for disassembling fire alarm equipment. Background Technology

[0002] Manual fire alarm buttons (referred to as manual alarms) and fire alarm audible and visual alarms (referred to as alarms) installed and sold on the market typically consist of two main parts: a mounting base and a control module. These devices have a mature structure, are easy to install, and are widely used in various building fire protection systems. They offer advantages such as flexible layout and convenient assembly and disassembly, providing crucial protection for fire early warning and personnel evacuation.

[0003] The base and control module of this type of fire alarm equipment are usually fixed using a snap-fit ​​connection structure. Due to the compact overall design and the fact that the equipment casing is mostly made of rigid plastic with high material rigidity, the snaps must be retracted inwards to disassemble the device. In practice, specialized disassembly tools are often lacking, and construction or maintenance personnel typically use general-purpose tools such as screwdrivers for disassembly.

[0004] However, there are obvious drawbacks to using non-specialized tools such as screwdrivers for disassembly: on the one hand, due to the small size of the equipment and limited operating space, it usually requires two people to work together to complete the disassembly, making collaborative work difficult; on the other hand, due to the hardness of the plastic material, the force required for the clips to retract is relatively large, and the screwdriver is prone to slipping when subjected to force, which not only increases the difficulty of operation, but also makes it very easy for the operator to be injured due to tool slippage. Utility Model Content

[0005] This utility model provides a tooling for disassembling fire alarm equipment, which solves the problem that the traditional method of disassembling fire alarm equipment using screwdrivers and other general tools affects work efficiency and brings safety hazards.

[0006] The present invention provides a fire alarm equipment disassembly fixture, comprising a fixture body. The fixture body is provided with multiple actuating parts, each actuating part being configured to be inserted into a corresponding slot of the fire alarm equipment; wherein, the multiple actuating parts are configured to simultaneously drive multiple latches to retract inward within the slots during operation, so as to disengage the latches from the slots.

[0007] Beneficial effects: By setting multiple actuators corresponding to the positions of the locking holes, a synchronous action relationship can be established after insertion. A single application of force by the operator can cause all the locking devices to retract inward simultaneously, eliminating the difficulty of two-person coordination caused by limited operating space when using general tools such as screwdrivers. This allows a single person to efficiently complete the disassembly operation. Simultaneously, during use, the actuators of the tool body precisely match the locking holes of the fire-fighting equipment, ensuring that the force is always transmitted along the direction of locking device retraction. This avoids hand scratches or equipment surface damage that may be caused by tool slippage, thus eliminating the risk of slippage and making the locking device disengagement process smoother and more reliable, improving the safety of equipment disassembly.

[0008] In one alternative embodiment, the tooling bodies are provided in a pair, the pair of tooling bodies are rotatably connected, and are configured such that an operator drives the two tooling bodies to rotate in opposite directions around a rotation axis, thereby enabling the actuators provided on the two tooling bodies to move toward each other and simultaneously enter oppositely arranged slots, or enabling the actuators provided on the two tooling bodies to move away from each other and simultaneously exit from their respective slots.

[0009] Beneficial effects: By employing a pair of rotatably connected tooling bodies, the operator drives the two tooling bodies to rotate around the rotation axis in opposite directions, enabling precise movement of the actuators in both directions. When the actuators move in opposite directions, the latches can simultaneously retract inwards, avoiding the distortion of the equipment housing, stress concentration, or one-sided wear of the latches caused by individual disassembly or uneven force, which is common in traditional methods. This maximizes the protection of the plastic latches and their mounting structure, extending the equipment's service life under repeated maintenance and repairs.

[0010] In one alternative embodiment, the fire alarm equipment disassembly fixture further includes a pivot shaft, through which a pair of fixture bodies are rotatably connected.

[0011] Beneficial effects: By using a rotating shaft as the core rotating component, a pair of tool bodies are rigidly connected in rotation, so that the pair of tool bodies rotate strictly around the rotating shaft, eliminating possible lateral sway or longitudinal movement during movement, ensuring that the trajectory of all actuators is consistent when inserting and withdrawing from the locking hole, avoiding problems such as misalignment, jamming or wear caused by inaccurate movement, and achieving accurate reproduction of every disassembly action.

[0012] In one optional embodiment, the tooling body further includes a mounting part and a handle part. The mounting part is used to mount the actuating part. The handle part is connected to each of the actuating parts through the mounting part and is configured to drive the tooling body and the plurality of actuating parts disposed thereon to move synchronously by the force applied by the operator, so that each of the actuating parts can disengage from the corresponding locking hole at the same time.

[0013] Beneficial effects: By forming a structure of handle, mounting part and actuator, the handle, as the only input end, can synchronously transmit the force applied by the operator to all actuators. This allows the operator to apply only a single force to synchronously drive the tool body and all actuators to move along a predetermined path, achieving synchronous retraction and disengagement of multiple latches. A single person can complete the disassembly operation efficiently, significantly improving maintenance efficiency.

[0014] In one optional embodiment, the tooling body further includes a connecting portion, which is installed between the mounting portion and the handle portion.

[0015] Beneficial effects: By setting the connecting part as a transition structure between the mounting part and the handle part, it is ensured that the external force applied by the operator to the handle part can be efficiently and evenly transmitted to each actuating part through the connecting part and the mounting part.

[0016] In one alternative embodiment, the mounting portion, the handle portion, and the connecting portion are integrally formed.

[0017] Beneficial effects: By molding the mounting part, handle part and connecting part into one piece, the tool body becomes a complete mechanical unit, and the force flow can be smoothly transmitted within the continuous material, which greatly improves the fatigue life and load-bearing limit of the tool under repeated stress.

[0018] In one alternative embodiment, the handle portion has a streamlined structure.

[0019] Beneficial effects: By designing the handle with a streamlined structure, the overall contour of the operator's grip can be optimized, so that the operator can grip it evenly and conform to the curve of the palm, further reducing the risk of accidental scratches or crush injuries caused by tool slippage during traditional disassembly.

[0020] In one alternative embodiment, the end of the actuating part that is away from the mounting part is rounded.

[0021] Beneficial effects: By rounding the end of the actuator away from the mounting part, a smooth guide surface is formed at the front end of the actuator entering the locking hole, guiding the actuator to the correct position in the locking hole, such as the alignment process between the actuator and the locking hole; at the same time, the rounding treatment reduces the contact area between the actuator and the locking hole, which can reduce the sliding friction force of the actuator sliding into the locking hole.

[0022] In one alternative embodiment, the actuators on a pair of tooling bodies are arranged symmetrically with respect to the central axis.

[0023] Beneficial effects: By setting the drive unit of the disassembly fixture to a symmetrical layout about the central axis, it is ensured that the actuators on the two fixture bodies always move symmetrically during rotation, so that each actuator can be inserted into the locking hole synchronously and accurately and drive the locking buckle to retract synchronously, thus achieving synchronous disengagement and avoiding the risk of the equipment being pried open on one side or the locking buckle being cut at an angle due to asynchronous actions.

[0024] In one alternative embodiment, the tooling body has a plate-like structure.

[0025] Beneficial effects: By setting the tooling body as a plate structure, the volume of the disassembly tooling can be reduced, and the difficulty of using the disassembly tooling in a compact space can be reduced. Attached Figure Description

[0033] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0034] According to an embodiment of this utility model, the provided fire alarm equipment disassembly fixture, such as... Figure 1 and Figure 2 As shown, the fixture includes a tooling body 1. The tooling body 1 is provided with a plurality of actuators 101, each actuator 101 being configured to be inserted into a corresponding slot of a fire alarm device; wherein, the plurality of actuators 101 are configured to simultaneously drive a plurality of latches to retract inward within the slots during operation, so that the latches disengage from the slots.

[0035] With this configuration, by setting multiple actuators 101 corresponding to the positions of the clip holes, a synchronous action relationship can be established after insertion. The operator can apply force once to make all the clips retract inward at the same time, eliminating the problem of difficulty in coordination between two people caused by limited operating space when using general tools such as screwdrivers. This allows a single person to efficiently complete the disassembly operation.

[0036] Meanwhile, during use, the actuator 101 of the tool body 1 is precisely matched with the buckle hole of the fire-fighting equipment, so that the force is always transmitted along the direction of buckle retraction, avoiding hand scratches or equipment surface damage that may be caused by tool slippage, thereby eliminating the risk of slippage, making the buckle disengagement process more stable and reliable, and improving the safety of equipment disassembly.

[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, the tooling body 1 is provided in a pair, the pair of tooling bodies 1 are rotatably connected, and are configured so that the operator drives the two tooling bodies 1 to rotate in opposite directions around a rotation axis, so that the actuators 101 provided on the two tooling bodies 1 can move towards each other and simultaneously enter the oppositely arranged slots, or so that the actuators 101 provided on the two tooling bodies 1 can move away from each other and simultaneously be taken out from the slots.

[0038] With this configuration, by adopting a pair of rotatably connected tooling bodies 1, the operator can drive the two tooling bodies 1 to rotate in opposite directions around the rotation axis, so that the actuator 101 can achieve precise movement in opposite directions.

[0039] When the actuators 101 move toward each other, the latches can retract inwards simultaneously, avoiding the distortion of the equipment housing, stress concentration, or one-sided wear of the latches caused by disassembling them one by one or uneven force in traditional methods. This maximizes the protection of the plastic latches and their installation structure, and extends the service life of the equipment under repeated maintenance and repair.

[0040] In one embodiment, such as Figure 1 As shown, the fire alarm equipment disassembly fixture also includes a rotating shaft 2, and a pair of fixture bodies 1 are rotatably connected through the rotating shaft 2.

[0041] With this configuration, by using the rotating shaft 2 as the core rotating component, a pair of tool bodies 1 are rigidly rotatably connected, so that the pair of tool bodies 1 rotate strictly around the rotating shaft 2, eliminating possible lateral swaying or longitudinal movement during the movement, ensuring that the trajectory of all actuators 101 when inserting and withdrawing from the locking hole is consistent, avoiding problems such as misalignment, jamming or wear caused by inaccurate movement, and achieving accurate reproduction of each disassembly action.

[0042] In one embodiment, such as Figure 1 and Figure 2As shown, the tooling body 1 also includes a mounting part 102 and a handle part 103. The mounting part 102 is used to mount the actuator 101. The handle part 103 is connected to each actuator 101 through the mounting part 102 and is configured to drive the tooling body 1 and the plurality of actuators 101 disposed thereon to move synchronously by the force applied by the operator, so that each actuator 101 can disengage from the corresponding locking hole at the same time.

[0043] This configuration, by forming a structure of handle 103, mounting part 102, and actuation part 101, allows the handle 103 to act as the sole input end, synchronously transmitting the force applied by the operator to all actuation parts 101. This enables the operator to apply only a single force to synchronously drive the tooling body 1 and all actuation parts 101 to move along a predetermined path, achieving synchronous retraction and disengagement of multiple latches. This allows a single person to complete efficient disassembly operations, significantly improving maintenance efficiency.

[0044] In one embodiment, such as Figure 1 and Figure 2 As shown, the tooling body 1 also includes a connecting part 104, which is installed between the mounting part 102 and the handle part 103.

[0045] With this configuration, by setting the connecting part 104 as a transition structure between the mounting part 102 and the handle part 103, it is ensured that the external force applied by the operator to the handle part 103 can be efficiently and evenly transmitted to each actuator part 101 through the connecting part 104 and the mounting part 102.

[0046] It can be noted that the rotating shaft 2 is installed in the connecting part 104. When it is necessary to disengage from the latch, the tool body 1 forms a lever structure, using the lever principle to save operating force.

[0047] It can be noted that the mounting part 102, the handle part 103, and the connecting part 104 are integrally formed.

[0048] With this configuration, by integrally molding the mounting part 102, the handle part 103 and the connecting part 104, the tool body 1 becomes a complete mechanical unit, allowing force to be smoothly transmitted within the continuous material, which greatly improves the fatigue life and load-bearing limit of the tool under repeated stress.

[0049] It can be noted that the handle part 103 has a streamlined structure.

[0050] This design, by making the handle 103 a streamlined structure, optimizes the overall contour of the operator's grip, ensuring that the force is evenly distributed and conforms to the curve of the palm when the operator grips it, further reducing the risk of accidental scratches or crush injuries caused by tool slippage during traditional disassembly.

[0051] In one embodiment, such as Figure 1and Figure 2 As shown, the end of the actuator 101 that is away from the mounting part 102 has a rounded corner.

[0052] With this configuration, by rounding the end of the actuating part 101 away from the mounting part 102, a smooth guide surface is formed at the front end of it entering the card hole, guiding it to slide into the correct position of the card hole and achieving alignment with the card hole.

[0053] Meanwhile, the rounded corners reduce the contact area between the actuator 101 and the locking hole, thereby reducing the friction when the actuator 101 slides into the locking hole.

[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the actuators 101 on a pair of tool bodies 1 are arranged symmetrically with respect to the central axis.

[0055] This configuration, by setting the drive unit 101 of the disassembly fixture to a symmetrical layout about the central axis, ensures that the actuators 101 on the two fixture bodies 1 always move symmetrically during rotation, so that each actuator 101 can be inserted into the card hole synchronously and accurately and drive the buckle to retract synchronously, thus achieving synchronous disengagement and avoiding the risk of the equipment being pried open on one side or the buckle being cut at an angle due to asynchronous actions.

[0056] It can be noted that each tool body 1 is provided with at least one actuating part 101.

[0057] Furthermore, the layout of the actuators 101 of the disassembly fixture is not specifically limited, but is determined based on the actual number and location of the clips in the fire alarm equipment and other disassembly requirements.

[0058] For example, when the locking holes on the fire alarm equipment are arranged in two sets of a total of four symmetrical layouts and all locking holes are at the same height, in order to match the four locking holes that are symmetrical in pairs and located on the same plane, the four actuators 101 of the disassembly tool adopt the same coplanar layout to ensure that they can be synchronously and accurately aligned and inserted into all locking holes during operation.

[0059] It can be explained that the connecting parts 104 of the two tool bodies 1 are arranged crosswise through the rotating shaft 2. When in use, the two tool bodies 1 rotate around the rotating shaft 2.

[0060] In one embodiment, such as Figure 1 and Figure 2 As shown, the tooling body 1 has a plate-like structure.

[0061] This design, by setting the tooling body 1 as a plate structure, can reduce the volume of the disassembly tooling and reduce the difficulty of using the disassembly tooling in a compact space.

[0062] It can be noted that the tool body 1 is made of steel.

[0063] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
