Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to a fire extinguisher clamping device and maintenance tooling. Background Technology

[0002] Aircraft fire extinguishers come in various shapes and sizes, including cylindrical and spherical. Spherical fire extinguishers are used to extinguish fires in the engine nacelle, wings, and other easily flammable areas inside the engine. Cylindrical fire extinguishers are used to locate and extinguish fires in the engine nacelle, wings, and other easily flammable areas inside the engine.

[0003] To ensure safe use, fire extinguishers require regular maintenance. During maintenance, the fire extinguisher needs to be clamped and secured using a clamping fixture before further repairs can be performed. For example, patent document CN219819416U discloses a fire extinguisher maintenance fixture equipped with a fixed clamp and a movable clamp. The clamping action of the fixed and movable clamps secures the fire extinguisher, allowing for its maintenance.

[0004] To ensure the stability of fire extinguishers, the fixed clamps and movable clamps are usually designed with an arc shape to fit the fire extinguisher. This means that maintenance tools can only be used to clamp fire extinguishers that are compatible with the size of the arc shape. When clamping other types and sizes of fire extinguishers, other maintenance tools that are compatible with the size of the fire extinguisher are required, resulting in higher maintenance costs for fire extinguishers. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a fire extinguisher clamping device and maintenance tooling to solve the technical problem that the existing technology requires the use of different fire extinguisher maintenance tooling when maintaining fire extinguishers of different sizes, resulting in high maintenance costs for fire extinguishers.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] Firstly, this utility model provides a fire extinguisher clamping device, comprising:

[0008] First clamp;

[0009] The second clamp is connected to the first clamp and can move relative to the first clamp;

[0010] The first clamp is detachably connected to the first belt clamp;

[0011] The second clamp is detachably connected to the second clamp and forms a locking space with the first clamp, the locking space being used for installing a fire extinguisher; and

[0012] A locking element connects the first clamp and the second clamp, restricting the relative movement of the first clamp and the second clamp.

[0013] In some embodiments, one end of the second clamp is hinged to the first clamp, and the other end of the second clamp can be connected to the first clamp by the rotation of the second clamp. The locking member connects the opposite ends of the first clamp and the second clamp, restricting the relative rotation of the second clamp and the first clamp.

[0014] In some embodiments, the opposite ends of the first clamp and the second clamp respectively have a first joint and a second joint, and the first clamp and the second clamp can be connected by the first joint and the second joint.

[0015] In some embodiments, the locking element includes a connector and a lock head, the connector being connected to the first pair of connectors, and the lock head being connected to the connector and abutting against another second pair of connectors to restrict relative movement between the first pair of connectors and the second pair of connectors.

[0016] In some embodiments, the connector has a threaded connecting rod, the lock head is threadedly connected to the threaded connecting rod, and can abut against the second coupling by axial movement along the threaded connecting rod.

[0017] In some embodiments, the connector is hinged to the first mating head, and the locking head can disengage from the second mating head by rotation of the connector.

[0018] In some embodiments, both the first clamp and the second clamp include an insertion end and a limiting end. The insertion end is movably inserted into the inner side of the first clamp and the second clamp and fits against the second clamp. The limiting end is connected to the insertion end and abuts against the end face of the first clamp and the second clamp.

[0019] In some embodiments, the inner side of the insertion end has locking protrusions spaced apart along the circumferential direction of the insertion end.

[0020] Secondly, this utility model provides a fire extinguisher maintenance fixture, including a fixed frame, a support base, and the aforementioned fire extinguisher clamping device. The support base and the fire extinguisher clamping device are both fixed to the fixed frame, and the support base is opposite to the fire extinguisher clamping device to support the fire extinguisher.

[0021] In some embodiments, the maintenance fixture further includes a tool rack, which is fixed to the fixed frame and together with the fixed frame forms a tool placement opening for placing maintenance tools.

[0022] Compared with the prior art, the fire extinguisher clamping device provided by this utility model is configured with a first clamp, a second clamp, a first clip, a second clip, and a locking element. The first clamp and the second clamp are connected, the first clip is connected to the first clamp, and the second clip is connected to the second clamp, so that the first clip and the second clip are respectively formed inside the first clamp and the second clip. The first clip and the second clip enclose a locking space. When the first clamp and the second clamp are close together, the locking space can be reduced, thereby locking the fire extinguisher in the locking space. The locking element connects the first clamp and the second clamp, and locks the first clamp and the second clamp by restricting the relative movement of the first clamp and the second clamp, thereby facilitating the maintenance of the fire extinguisher. Since the first clip and the second clip can be disassembled relative to each other, when performing clamping and maintenance work on fire extinguishers of different sizes and types, only the first clip and the second clip of the corresponding size need to be replaced, without having to replace the entire maintenance tooling, thereby reducing the maintenance cost of the fire extinguisher.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] To address the technical problem that existing technologies require different fire extinguisher repair fixtures for repairing fire extinguishers of different sizes, resulting in high repair costs, this utility model provides a fire extinguisher clamping device. This device can be installed on the fire extinguisher repair fixture to assist in the repair of the fire extinguisher. It can clamp fire extinguishers of any size without replacing the entire repair fixture, thereby reducing the repair cost.

[0036] It should be noted that the fire extinguisher clamping device described in this utility model is used, but not limited to, fire extinguisher maintenance tools, and can also be applied to fire extinguisher disassembly tools. For ease of explanation, this utility model only uses the application of the fire extinguisher clamping device to fire extinguisher maintenance tools as an example. The principle of the fire extinguisher clamping device applied to other equipment is essentially the same as that applied to fire extinguisher maintenance tools, and will not be elaborated here.

[0037] The fire extinguisher clamping device provided in this embodiment of the utility model, such as Figure 1 and 3 As shown, the device includes a first clamp 10, a second clamp 20, a first clamp 30, a second clamp 40, and a locking member 50. The second clamp 20 is connected to the first clamp 10 and can move relative to the first clamp 10. The first clamp 30 is detachably connected to the first clamp 10. The second clamp 40 is detachably connected to the second clamp 20 and together with the first clamp 30 forms a locking space 41, which is used for installing a fire extinguisher. The locking member 50 connects the first clamp 10 and the second clamp 20, restricting the relative movement of the first clamp 10 and the second clamp 20, so that the first clamp 30 and the second clamp 40 clamp the fire extinguisher in the locking space 41.

[0038] Specifically, the fire extinguisher clamping device comprises a first clamp 10, a second clamp 20, a first clamp 30, a second clamp 40, and a locking element 50. The first clamp 10 and the second clamp 20 are connected, the first clamp 30 is connected to the first clamp 10, and the second clamp 40 is connected to the second clamp 20, such that the first clamp 30 and the second clamp 40 are respectively formed inside the first clamp 10 and the second clamp 20. The first clamp 30 and the second clamp 40 enclose a locking space 41. When the first clamp 10 and the second clamp 20 are close together, the locking space 41 is reduced, thereby locking the fire extinguisher within the locking space 41. The locking element 50 is connected to the first clamp 10, the second clamp 20, the first clamp 30, the second clamp 40, and the locking element 50. The clamps 10 and 20, by restricting the relative movement of the clamps 10 and 20, lock the clamps 10 and 20, thereby facilitating the maintenance of the fire extinguisher. Since the clamps 30 and 40 can be disassembled relative to the clamps 10 and 20, when performing clamping and maintenance work on fire extinguishers of different sizes, it is only necessary to replace the clamps 30 and 40 with the corresponding thicknesses and adapt the size of the locking space 41 when the clamps 10 and 20 are connected, without having to replace the entire maintenance tooling, thus reducing the maintenance cost of the fire extinguisher.

[0039] In this embodiment, when clamping the fire extinguisher, first open the first clamp 10 and the second clamp 20, then select the appropriate size first clamp 30 and second clamp 40, install the first clamp 30 and the second clamp 40 inside the first clamp 10 and the second clamp 20, then place the fire extinguisher in the locking space 41, and then close the first clamp 10 and the second clamp 20, which will drive the first clamp 30 and the second clamp 40 to lock the fire extinguisher, and then the locking member 50 will lock the first clamp 10 and the second clamp 20.

[0040] Understandably, the first clamp 10 can be moved relative to the first clamp 10 by setting a sliding rod, and the second clamp 20 can be slidably connected to the sliding rod.

[0041] In this embodiment, the first clamp 30 is connected to the side of the first clamp 10 near the second clamp 20, and the second clamp 40 is connected to the side of the second clamp 20 near the first clamp 10.

[0042] In one embodiment, such as Figure 1 and 3As shown, one end of the second clamp 20 is hinged to the first clamp 10, and the other end of the second clamp 20 can be connected to the first clamp 10 by rotating the second clamp 20. The locking member 50 connects the opposite ends of the first clamp 10 and the second clamp 20, restricting the relative rotation of the second clamp 40 and the first clamp 10. Specifically, by hinged to the first clamp 10, the second clamp 20 can move relative to the first clamp 10 by rotating. When clamping the fire extinguisher, the second clamp 20 rotates away from the first clamp 10. Then, the first clamp 30 and the second clamp 40 of appropriate size are installed inside the first clamp 10 and the second clamp 20. The fire extinguisher is then placed in the locking space 41, and by rotating the second clamp 20, it is connected to the first clamp 10, so that the first clamp 30 and the second clamp 40 clamp the fire extinguisher, thus facilitating the clamping of the fire extinguisher.

[0043] In this embodiment, as Figure 3 As shown, to achieve a stable hinged connection between the first clamp 10 and the second clamp 20, the end of the first clamp 10 has a fitting groove 11, and the end of the second clamp 20 has a fitting protrusion 21, which fits into the fitting groove 11. The fitting protrusion 21 and the fitting groove 11 fit together to ensure a tight connection between the first clamp 10 and the second clamp 20.

[0044] Understandably, the fitting protrusion 21 can be provided with protrusion structures on both sides to cooperate with the side wall of the fitting groove 11 to achieve hinge connection.

[0045] In this embodiment, the pin passes through the first clamp 10 and the fitting protrusion 21, so that the second clamp 20 can rotate around the pin, thereby achieving the hinge connection between the second clamp 20 and the first clamp 10.

[0046] In one embodiment, such as Figure 1 and 3 As shown, the opposite ends of the first clamp 10 and the second clamp 20 respectively have a first mating joint 12 and a second mating joint 22, which can be connected to form a joint. Specifically, the stable connection of the first clamp 10 and the second clamp 20 is achieved through the mating cooperation of the first mating joint 12 and the second mating joint 22, thereby ensuring the locking force of the fire extinguisher.

[0047] Understandably, the first clamp 10 and the second clamp 20 can be installed by setting mounting grooves on their inner sides, so that when installing the first clamp 30 and the second clamp 40, they only need to be inserted into the mounting grooves.

[0048] In one embodiment, such as Figure 1 and 3As shown, both the first clamp 30 and the second clamp 40 include an insertion end 31 and a limiting end 32. The insertion end 31 is movably inserted into the inner side of the first clamp 10 and the second clamp 20, and fits against the second clamp 20. The limiting end 32 is connected to the insertion end 31 and abuts against the end faces of the first clamp 10 and the second clamp 20. Specifically, with the above-described configuration of the first clamp 30 and the second clamp 40, during installation, it is only necessary to insert the insertion end 31 of the first clamp 30 and the second clamp 40 into the inner side of the first clamp 10 and the second clamp 20, and then the limiting end 32 will naturally limit the clamp, thus facilitating the installation and removal of the first clamp 30 and the second clamp 40.

[0049] In one embodiment, such as Figure 1 and 3 As shown, the inner side of the insertion end 31 has locking protrusions 33 spaced apart along the circumferential direction of the insertion end 31. Specifically, the locking protrusions 33 can increase the locking force of the fire extinguisher and achieve stable locking of the fire extinguisher.

[0050] Understandably, the locking member 50 can be a bolt threaded to the first connector 12 and the second connector 22, or a clamping member clamped to the first connector 12 and the second connector 22, thereby locking the first clamp 10 and the second clamp 20 through threaded connection or clamping action.

[0051] In one embodiment, such as Figure 1-3 As shown, the locking member 50 includes a connector 51 and a lock head 52. The connector 51 is connected to the first coupling 12, and the lock head 52 is connected to the connector 51 and abuts against another second coupling 22, restricting the relative movement of the first coupling 12 and the second coupling 22. Specifically, with the above-described arrangement of the locking member 50, when the first clamp 10 and the second clamp 20 are locked, the lock head 52 slides along the connector 51 and abuts against the second coupling 22, thereby limiting the position of the first coupling 12 and the second coupling 22.

[0052] Understandably, the lock head 52 can be relatively fixed to the connector head 51 by snapping it into place.

[0053] In one embodiment, such as Figure 2 As shown, the connector 51 has a threaded connecting rod 511, and a locking head 52 is threadedly connected to the threaded connecting rod 511 and can abut against the second coupling 22 by moving axially along the threaded connecting rod 511. Specifically, when locking the first clamp 10 and the second clamp 20, it is only necessary to thread the locking head 52 onto the threaded connecting rod 511 after the first coupling 12 and the second coupling 22 are mated, and then tighten it to abut against the second coupling 22 to lock the second coupling 22.

[0054] In one embodiment, such as Figure 1 and 3 As shown, connector 51 is hinged to first connector 12, and lock head 52 can disengage from second connector 22 by rotating connector 51. Specifically, by hinged connector 51 to first connector 12, when unlocking first clamp 10 and second clamp 20, it is only necessary to first loosen lock head 52 and disengage it from second connector 22, then manipulate lock head 52 to rotate connector 51, moving lock head 52 away from second connector 22, thereby unlocking second clamp 20, and then the fire extinguisher can be installed.

[0055] This utility model provides a fire extinguisher maintenance tool, such as Figure 3 As shown, the device includes a fixing frame 60, a support base 70, and a fire extinguisher clamping device. Both the support base 70 and the fire extinguisher clamping device are fixed to the fixing frame 60. The support base 70 is opposite to the fire extinguisher clamping device to support the fire extinguisher. Specifically, during fire extinguisher maintenance, the fire extinguisher is locked by the first clamp 30 and the second clamp 40, and its bottom is supported by the support base 70, achieving stability. This assists in fire extinguisher maintenance, allowing for the clamping of fire extinguishers of any size without requiring a complete replacement of the maintenance tooling, thereby reducing fire extinguisher maintenance costs.

[0056] In one embodiment, such as Figure 3 As shown, the maintenance tooling also includes a tool rack 80, which is fixed to the fixed frame 60 and together with the fixed frame 60 forms a tool placement opening 81 for placing maintenance tools. Specifically, the tool placement opening 81 is used to place tools for maintenance, facilitating the maintenance of fire extinguishers.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: When performing maintenance work on a fire extinguisher, first loosen the lock head 52 and disengage it from the second coupling 22. Then, manipulate the lock head 52 to rotate the connector 51, moving the lock head 52 away from the second coupling 22 and unlocking the second clamp 20. Then, rotate the second clamp 20 away from the first clamp 10. Next, select a suitable size first clamp 30 and second clamp 40 and install them inside the first clamp 10 and second clamp 20. Then, place the fire extinguisher in the locking space 41 and support it with the support base 70. Then, rotate the second clamp 20 to align it with the first clamp 10. Then, rotate the locking part 50 and finally tighten the lock head 52 so that it abuts against the second coupling 22. This facilitates the maintenance of the fire extinguisher, and only requires adaptive replacement of the first clamp 30 and second clamp 40 to achieve clamping and maintenance of fire extinguishers of different sizes, reducing the maintenance cost of fire extinguishers.

[0058] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
