Description

Technical Field

[0001] This invention relates to the field of mechanical transmission structures, and more specifically to a tripping structure. Background Technology

[0002] Books, documents, and other paper items stored on bookshelves or in display cases in libraries or museums can be damaged in the event of a sudden fire, a leak in the building, or damage to the water supply, heating, or automatic fire extinguishing system pipelines (which is more likely than a fire).

[0003] Currently, there are no protective measures for bookshelves or museum display cases that simultaneously address waterproofing and fireproofing. Furthermore, conventional devices used for triggering mechanisms often employ internal or external power supplies and control circuits. However, power outages are common in libraries or museums during fires, and the wiring can be damaged by high temperatures or water accumulation, leading to trigger failure. Moreover, both fires and floods are typically low-probability events, which can lead to complacency among maintenance personnel, resulting in insufficient and untimely maintenance of the electrical components used for triggering, causing the triggers to fail to respond promptly. Therefore, if applied to the protective mechanism described in this application, it would be difficult to reliably and effectively protect exhibits or books in the event of a fire or flood. Summary of the Invention

[0004] The purpose of this invention is to provide a tripping structure to ensure that fire or flood protection measures on bookshelves and display cases can be reliably triggered and activated.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tripping structure, comprising: Frame; The first support rod has one end set on the frame and the other end used to connect to the lifting ring. The sleeve is movably fitted onto the first support rod; A sliding member is slidably connected to the first support rod. One end of the sleeve abuts against the sliding member. The sliding member has a first limiting end and a second limiting end that are respectively located on both sides of the first support rod. The sliding member is used to slide along the axial direction of the first support rod to push the sleeve to drop the lifting ring. The first elastic element is sleeved on the first support rod, and the two ends of the first elastic element act elastically on the frame and the sliding element respectively, so as to apply an elastic force to the sliding element in the direction of the sleeve. The first sensing component is hinged or abutted to the first limiting end at one end, and the other end of the second sensing component abuts or is connected to the frame. The first sensing component is used to break at high temperature to release the support and limitation on the first limiting end of the sliding member. The lever structure has its rotation axis located on the frame. The second sensing component is pulled and limited at one end to one end of the lever structure, and the other end of the first sensing component is connected to the frame. The other end of the lever structure abuts and limits the second limiting end. The second sensing component is used to expand and break when exposed to water, so as to release the pull and limit at one end of the lever structure.

[0006] Optionally, the above-mentioned tripping structure further includes: A guide member is provided on the frame, and the axis of the guide member is parallel to the axis of the first support rod. The guide member is slidably connected to the sliding member, and the guide member is used to guide the sliding member to move along the axis of the first support rod.

[0007] Optionally, in the above-mentioned tripping structure, the guide element includes: The second support rod is installed on the frame and is slidably connected to the sliding member; The second elastic element is sleeved on the second support rod, and the two ends of the second elastic element act elastically on the frame and the sliding element respectively, so as to apply an elastic force to the sliding element in the direction of the sleeve.

[0008] Optionally, in the above-mentioned tripping structure, two sets of guide members are provided, and the two sets of guide members are respectively provided on both sides of the first support rod.

[0009] Optionally, in the above-mentioned tripping structure, the sliding element is a sliding plate or a sliding rod, and the sliding plate or sliding rod is provided with a strip hole for the first support rod and the second support rod to pass through.

[0010] Optionally, in the above-mentioned tripping structure, the frame includes: Base plate; A first support plate is disposed on the base plate, and the first support plate is connected to the end of the first support rod away from the sleeve. The second support plate is disposed on the base plate, and the end of the first sensing component away from the slider is disposed on the second support plate; The third support plate is set on the base plate, the end of the second sensing component away from the lever structure is set on the third support plate, and the two ends of the second support rod are respectively set on the second support plate and the third support plate.

[0011] Optionally, the above-mentioned tripping structure further includes: The first mounting block is disposed on the side of the base plate where the first sensing component is located; The second mounting block is disposed on the side of the base plate where the second sensing component is disposed. Both the first mounting block and the second mounting block are used to fix the base plate to the bookshelf.

[0012] Optionally, in the above-mentioned release structure, the protrusion height of the first mounting block relative to the base plate is the same as that of the second mounting block relative to the base plate, and the protrusion height of any one of the first support rod, sleeve, sliding member, first elastic member, first sensing member, second sensing member and lever structure relative to the base plate is less than the protrusion height of the first mounting block relative to the base plate.

[0013] Optionally, in the above-mentioned tripping structure, the first sensing component includes: The first connecting rod is installed on the frame; The second connecting rod is rotatably connected to the first limiting end of the sliding member; A temperature-sensitive glass bulb is positioned between the first connecting rod and the second connecting rod, and the first sensing element is designed to break upon heating.

[0014] Optionally, in the above-mentioned tripping structure, the second sensing component includes: The third connecting rod is installed on the frame; The fourth connecting rod is rotatably connected to the second limiting end of the sliding member; Water-soluble fibers are placed between the third and fourth connecting rods. These fibers are designed to break upon contact with water.

[0015] Compared with existing technologies, when using the above technical solution, under normal working conditions without triggering, the lifting ring of the protective mechanism is sleeved on one end of the first support rod, the sleeve is in the non-protruding position, the first elastic element is in a compressed state, and the axial thrust exerted by the first elastic element on the sliding element is always present. This elastic thrust is balanced and offset by the support limit of the first sensing component and the abutment limit of the lever structure, keeping the sliding element in a state of force balance. When a fire occurs, the ambient temperature rises, causing the first sensing component to break due to high temperature, releasing the support limit of the first sensing component on the first limiting end of the sliding element. The second sensing component remains intact and continues to pull and limit one end of the lever structure, thereby abutting and limiting the second limiting end of the sliding element through the other end of the lever structure. The first elastic element elastically returns to its original compressed state, pushing the sleeve along the axial direction of the first support rod. The moving elastic force causes the sliding member to slide axially along the first support rod due to unbalanced force, which in turn pushes the sleeve to lift the ring off the first support rod. Since the ring is connected to the bookshelf protection mechanism, the activation of the bookshelf protection mechanism is completed after the ring is released from support. When indoor flooding occurs, water droplets fall onto the second sensing component, causing it to expand and break upon contact with water. This causes the tension force on the lever structure near the second sensing component to fail, and the lever structure rotates around the rotation axis, releasing the contact limit on the second limiting end of the sliding member. At this time, the first sensing component remains intact, with only the first sensing component limiting the first limiting end. The first elastic member elastically returns to its original state from compression, applying an elastic force to the sliding member to push the sleeve to move axially along the first support rod. This causes the sliding member to slide axially along the first support rod due to unbalanced force, which in turn pushes the sleeve to lift the ring off the first support rod, completing the activation of the bookshelf protection mechanism. Compared to trigger actuators that use external power supplies and control circuits, this application does not rely on external power supplies for triggering. Instead, it relies on the temperature sensing of the first sensing component and the water leakage sensing of the second sensing component to achieve automatic and reliable tripping through mechanical drive. This avoids the risk of trigger failure under extreme conditions such as high temperature or water leakage, ensuring the reliability and security of the protection of books, documents and other paper products stored in bookshelves and display cases in libraries or cultural and museum venues.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] like Figures 1-3 As shown, an embodiment of the present invention provides a release structure, including: a frame 1, a first support rod 2, a sleeve 3, a sliding member 41, a first elastic member 42, a first sensing component 5, a second sensing component 6, and a lever structure 7.

[0024] The first support rod 2 has one end attached to the frame 1 and the other end used to attach the lifting ring 9. A sleeve 3 is movably fitted onto the first support rod 2. A sliding member 41 is slidably connected to the first support rod 2, with one end of the sleeve 3 abutting against the sliding member 41. The sliding member 41 has a first limiting end and a second limiting end positioned opposite each other on both sides of the first support rod 2. The sliding member 41 is used to slide along the axial direction of the first support rod 2 to push the sleeve 3 to push the lifting ring 9 down. A first elastic member 42 is fitted onto the first support rod 2, and both ends of the first elastic member 42 elastically act on the frame 1 and the sliding member 41 respectively, for supporting the sliding member 41. 1. Apply elastic force towards the sleeve 3; one end of the first sensing component 5 is hinged or abutted to the first limiting end, and the other end of the second sensing component 6 abuts or is connected to the frame 1. The first sensing component 5 is used to break at high temperature to release the support and limitation on the first limiting end of the sliding member 41; the rotation shaft 71 of the lever structure 7 is set on the frame 1; one end of the second sensing component 6 is pulled and limited to one end of the lever structure 7, and the other end of the first sensing component 5 is connected to the frame 1. The other end of the lever structure 7 abuts and limits the second limiting end. The second sensing component 6 is used to expand and break after encountering water to release the pull and limit on one end of the lever structure 7.

[0025] In specific implementation, such as Figure 1 As shown, under normal operating conditions when the tripping structure is not triggered, the lifting ring 9, which belongs to the protective mechanism, is sleeved on one end of the first support rod 2, the sleeve 3 is in the non-protruding position, the first elastic element 42 is in a compressed state, and the axial thrust exerted by the first elastic element 42 on the sliding element 41 always exists. The elastic thrust of the first elastic element 42 is balanced and offset by the support limit of the first sensing component 5 and the abutment limit of the lever structure 7, so that the sliding element 41 is in a state of force balance. Figure 2As shown, when a fire occurs, the ambient temperature rises, causing the first sensing component 5 to break due to high temperature. This releases the support and limitation of the first sensing component 5 on the first limiting end of the sliding member 41. The second sensing component 6 remains intact and continues to pull and limit one end of the lever structure 7. The other end of the lever structure 7 then abuts and limits the second limiting end of the sliding member 41. The first elastic component 42 elastically resets from its compressed state, applying a spring force to the sliding member 41 to push the sleeve 3 to move axially along the first support rod 2. This causes the sliding member 41 to slide axially along the first support rod 2 due to unbalanced force, thus pushing the sleeve 3 to move and lift the lifting ring 9 off the first support rod 2. Since the lifting ring 9 is connected to the bookshelf protection mechanism, after the support is released, the bookshelf protection mechanism is activated. Figure 3 As shown, when indoor flooding occurs, water droplets fall onto the second sensing component 6, causing it to expand and break upon contact with water. This causes the pulling force of the lever structure 7 near the second sensing component 6 to fail, and the lever structure 7 rotates around the rotating shaft 71, releasing the pulling limit on the second limiting end of the sliding member 41. At this time, the first sensing component 5 remains intact, with only the first sensing component 5 limiting the first limiting end. The first elastic member 42 elastically resets from the compressed state, applying a spring force to the sliding member 41 to push the sleeve 3 to move axially along the first support rod 2. This causes the sliding member 41 to slide axially along the first support rod 2 due to unbalanced force, thereby pushing the sleeve 3 to move and lift the hanging ring 9 off the first support rod 2, completing the activation action of the bookshelf protection mechanism. Compared to trigger actuators that use external power supplies and control circuits, this application does not rely on external power to start triggering. Instead, it relies on the temperature sensing of the first sensing component 5 and the water leakage sensing of the second sensing component 6 to achieve automatic and reliable tripping through mechanical drive. This avoids the risk of trigger failure under extreme conditions such as high temperature or water leakage, and ensures the reliability and security of the protection of books, documents and other paper products stored in bookshelves and display cases in libraries or cultural and museum venues.

[0026] It should be noted that when indoor water damage occurs, water drips into the water collection tank of the bookshelf. The water inlet at the bottom of the water collection tank is located above the second sensing component 6, so that the water can accumulate in the water collection tank and then drip accurately into the second sensing component 6 through the water inlet, triggering the second sensing component 6 to expand and break when it comes into contact with water.

[0027] Specifically, in this embodiment, the release structure further includes a guide member 43, which is disposed on the frame 1 and whose axial direction is parallel to that of the first support rod 2. The guide member 43 is slidably connected to the sliding member 41 and is used to guide the sliding member 41 to move along the axial direction of the first support rod 2.

[0028] During operation, when the first sensing component 5 breaks due to high temperature, the support limit of the first limiting end is released. When the second sensing component 6 breaks due to expansion when exposed to water, the support limit of the second limiting end is released. Both the breakage of the first sensing component 5 and the breakage of the second sensing component 6 will cause the sliding component 41 to be unbalanced in force on the first support rod 2. The first elastic component 42 applies an elastic force to the sliding component 41, and the sliding component 41 slides along the axial direction of the first support rod 2 to push the sleeve 3 to move. During the movement, the sliding component 41 is limited by the guide component 43, so that the sliding component 41 can only move along the axial direction of the first support rod 2 to push the lifting ring 9 off the first support rod 2, and will not rotate relative to the axial direction of the first support rod 2 during the movement, further ensuring the stability and reliability of the release structure.

[0029] Specifically, in this embodiment, the guide member 43 includes: a second support rod 431 and a second elastic member 432. The second support rod 431 is disposed on the frame 1 and is slidably connected to the sliding member 41. The second elastic member 432 is sleeved on the second support rod 431, and the two ends of the second elastic member 432 elastically act on the frame 1 and the sliding member 41 respectively, for applying an elastic force to the sliding member 41 in the direction of the sleeve 3.

[0030] During operation, if either the first sensing component 5 or the second sensing component 6 breaks, the sliding member 41 will experience an imbalance of force on the first support rod 2. At this time, both the first elastic component 42 and the second elastic component 432 apply elastic force to the sliding member 41. The sliding member 41 slides along the axial direction of the first support rod 2, pushing the sleeve 3 to move. During the movement, the sliding member 41 is limited by the second support rod 431, so that the sliding member 41 can only move along the axial direction of the first support rod 2 to push the lifting ring 9 off the first support rod 2. It will not rotate relative to the axial direction of the first support rod 2 during the movement, thus ensuring the stability and reliability of the release structure.

[0031] Specifically, in this embodiment, two sets of guide members 43 are provided, with the two sets of guide members 43 respectively located on both sides of the first support rod 2. This arrangement ensures that when the first sensing component 5 or the second sensing component 6 breaks, the force on the sliding member 41 is more uniform, the movement of the sliding member 41 is more balanced, and the sliding member 41 can move relatively stably and in a balanced manner along the axial direction of the first support rod 2, thus lifting the lifting ring 9 off the first support rod 2 and ensuring the stability and reliability of the sliding member 41 during its sliding process.

[0032] Of course, in some embodiments, the guide member 43 may not be provided. When the release structure is installed at the bottom of the top plate of the bookshelf, the bottom of the top plate and the frame 1 of the release structure jointly restrict the sliding member 41 from rotating around the axis of the first support rod 2. As long as the sliding member 41 can move smoothly along the axial direction of the first support rod 2 without rotating around the axis of the first support rod 2, it is acceptable.

[0033] like Figures 1-3 As shown, in this embodiment, the sliding member 41 is a sliding plate or a sliding rod, and the sliding plate or sliding rod is provided with a strip-shaped hole for the first support rod 2 and the second support rod 431 to pass through. With this configuration, when the sliding member 41 is a sliding plate, the plate-like structure can increase the contact area between the sliding member 41 and the first elastic member 42 and the second elastic member 432, making the force on the sliding member 41 more uniform during sliding and ensuring that the sliding plate slides smoothly along the axial direction of the first support rod 2. When the sliding member 41 is a sliding rod, the rod-like structure can reduce the contact friction resistance during sliding and reduce the driving force required for the sliding member 41 to slide. Through the cooperation of the strip-shaped hole with the first support rod 2 and the second support rod 431, it avoids jamming between the sliding plate or sliding rod and the first support rod 2 and the second support rod 431 due to the sliding plate or sliding rod deviating towards the end that is released during movement, thus improving the stability and reliability of the release structure's sliding trigger to complete the release action of the lifting ring 9.

[0034] like Figures 1-3 As shown, in some embodiments, the frame 1 includes: a base plate 11, a first support plate 12, a second support plate 13, and a third support plate 14. The first support plate 12 is disposed on the base plate 11 and is connected to the end of the first support rod 2 away from the sleeve 3. The second support plate 13 is disposed on the base plate 11, and the end of the first sensing component 5 away from the sliding component 41 is disposed on the second support plate 13. The third support plate 14 is disposed on the base plate 11, and the end of the second sensing component 6 away from the lever structure 7 is disposed on the third support plate 14. The two ends of the second support rod 431 are respectively disposed on the second support plate 13 and the third support plate 14. With this arrangement, by all three supports (the first, second, and third) are disposed on the base plate 11, the structure on the frame 1 is compactly distributed, the support is stable, and the force distribution is uniform, improving the overall stability and reliability of the tripping structure and facilitating assembly and subsequent maintenance.

[0035] In this embodiment, the frame 1 further includes: a first mounting block 81 and a second mounting block 82. The first mounting block 81 is disposed on the side of the base plate 11 where the first sensing component 5 is disposed; the second mounting block 82 is disposed on the side of the base plate 11 where the second sensing component 6 is disposed. Both the first mounting block 81 and the second mounting block 82 are used to fix the base plate 11 to the bookshelf.

[0036] During operation, the operator uses mounting screws to install and fix the first mounting block 81 and the second mounting block 82 onto the bookshelf, completing the overall installation and fixation of the release structure. Specifically, the first mounting block 81 and the second mounting block 82 can be rectangular protrusions, cylindrical protrusions, or protrusions of other shapes, as long as the first mounting block 81 and the second mounting block 82 can be fixedly installed correspondingly to the bookshelf.

[0037] In some embodiments, the protrusion height of the first mounting block 81 relative to the base plate 11 is the same as the protrusion height of the second mounting block 82 relative to the base plate 11, and the protrusion height of any one of the first support rod 2, sleeve 3, sliding member 41, first elastic member 42, first sensing component 5, second sensing component 6, and lever structure 7 relative to the base plate 11 is less than the protrusion height of the first mounting block 81 relative to the base plate 11. With this configuration, after the release structure is installed and fixed at the corresponding position on the bookshelf, sufficient working space is formed between the bottom of the top plate of the bookshelf and the base plate 11 of the shelf body 1 by the first mounting block 81 and the second mounting block 82, ensuring that the bottom of the top plate of the bookshelf does not interfere with any of the structural components, such as the first support rod 2, sleeve 3, sliding member 41, first elastic member 42, first sensing component 5, second sensing component 6, and lever structure 7, thereby guaranteeing the stability and reliability of the release process.

[0038] Specifically, in this embodiment, the first sensing component 5 includes: a first connecting rod 51, a second connecting rod 52, and a temperature-sensing glass bulb 53. The first connecting rod 51 is disposed on the frame 1; the second connecting rod 52 is rotatably connected to the first limiting end of the sliding member 41; the temperature-sensing glass bulb 53 is disposed between the first connecting rod 51 and the second connecting rod 52, and the first sensing element is used to break when heated.

[0039] During operation, in the event of a fire, the ambient temperature rises sharply, causing the medium inside the temperature-sensing bulb 53 to expand due to heat, resulting in a continuous increase in internal pressure. When the temperature reaches a set threshold, the temperature-sensing bulb 53 ruptures, causing the support connection between the first connecting rod 51 and the second connecting rod 52 to fail. The first connecting rod 51 and the second connecting rod 52 disconnect from each other, releasing the support limit on the first limiting end. Only the second sensing component 6 limits the second limiting end. The sliding member 41, under unbalanced force, slides along the axial direction of the first support rod 2, pushing the sleeve 3. The movement of the sleeve 3 pushes the lifting ring 9 off the first support rod 2, completing the release action. Specifically, the medium inside the temperature-sensing bulb 53 can be a heat-sensitive liquid, an expanding gas, or other materials that can expand under high temperatures. Of course, it is not limited to the types listed in this embodiment, as long as the medium inside the temperature-sensing bulb 53 can expand due to heat at a set temperature and reliably rupture the bulb, thus disconnecting the connection between the first connecting rod 51 and the second connecting rod 52. In addition, the temperature-sensing glass bulb 53 breaks upon heating, eliminating the need for complex circuitry and power supply structures and avoiding aging failure issues. It is triggered solely by physical and mechanical means, thus improving the reliability of the tripping structure.

[0040] In some other embodiments, the first sensing component 5 may also include only a temperature-sensing glass bulb 53. The two ends of the temperature-sensing glass bulb 53 are supported and abutted against the first limiting end of the frame 1 and the sliding member 41. After being heated and broken, the support and limiting of the first limiting end of the sliding member 41 can be released, thereby realizing the release of the release structure.

[0041] In this embodiment, the second sensing component 6 includes: a third connecting rod 61, a fourth connecting rod 62, and a water-soluble fiber 63. The third connecting rod 61 is disposed on the frame 1; the fourth connecting rod 62 is rotatably connected to the second limiting end of the sliding member 41; the water-soluble fiber 63 is disposed between the third connecting rod 61 and the fourth connecting rod 62, and the water-soluble fiber 63 is used to break when exposed to water.

[0042] During operation, when indoor flooding occurs, water drips onto the water-soluble fiber 63. The water-soluble fiber 63 gradually dissolves upon contact with water, and its strength decreases. When the degree of dissolution of the water-soluble fiber 63 reaches a critical state, it breaks, causing the tension connection between the third connecting rod 61 and the fourth connecting rod 62 to fail. The third connecting rod 61 and the fourth connecting rod 62 disconnect from each other, releasing the tension limit on the second limiting end. Only the first sensing component 5 limits the first limiting end. The sliding component 41, under unbalanced force, slides along the axial direction of the first support rod 2, pushing the sleeve 3. The movement of the sleeve 3 pushes the lifting ring 9 off the first support rod 2, completing the release action. Specifically, the water-soluble fiber 63 can be water-soluble cotton fiber, water-soluble polyester fiber, or other fiber materials that can dissolve and break upon contact with water. Of course, it is not limited to the types listed in this embodiment, as long as it ensures that the water-soluble fiber 63 can reliably dissolve and break upon contact with water, thereby disconnecting the connection between the third connecting rod 61 and the fourth connecting rod 62.

[0043] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
