Description

Technical Field

[0001] This utility model belongs to the field of fire protection testing technology, specifically relating to a fire protection testing device that is easy to install and store. Background Technology

[0002] Fire protection testing requires the use of various testing components on-site, such as fire pipeline pressure testers, water flow meters, and smoke sensor calibrators. These components are often characterized by small size, precise structure, and high unit price. Therefore, there are high requirements for the portability, protection, and ease of access of their storage devices.

[0003] In existing fire protection testing, testing components are usually stored in toolboxes. The toolboxes use simple fixed partitions to position the testing components. To prevent the components from shaking, the gap between the slot and the component is usually small. When removing the component, the fingers need to go deep into the slot to dig it out. For components that are small or have precision interfaces, digging can not only easily scratch the operator's fingernails, but may also cause deformation of the component interface or bending of the probe due to improper force, affecting the testing accuracy or even directly damaging the component. Utility Model Content

[0004] The purpose of this utility model is to provide a fire detection device that is easy to install and store, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A fire detection device that is easy to install and store, including a toolbox. The toolbox is equipped with a protective plate inside. The surface of the protective plate has multiple component slots. The shape of the component slots is the same as that of the fire detection components. A lifting mechanism is provided below the protective plate. The lifting mechanism includes a lifting plate. A limiting groove is formed in the inner wall of the toolbox. The end of the lifting plate is movably engaged in the limiting groove. A plurality of lifting columns are provided on the surface of the lifting plate. The number of lifting columns matches the number of component slots, and the lifting columns are located directly below the component slots. A cam is provided below the lifting plate. The end of the cam is connected to the inner wall of the toolbox through a rotating shaft. An operating component is provided on the side of the cam.

[0006] In a preferred embodiment of this utility model, the operating component includes a swing arm, the bottom end of which is fixedly sleeved on the rotating shaft surface at the end of the cam. An operating space is provided inside the toolbox and on one side of the protective plate, and the swing arm is movably disposed in the operating space.

[0007] As a preferred embodiment of this utility model, a spring is provided at the bottom of the toolbox, and the top of the spring is connected to the cam.

[0008] As a preferred embodiment of this utility model, a positioning block is provided through the toolbox on the side near the operating space, a rectangular groove is provided on the outer side of the toolbox, a pull plate is movably provided inside the rectangular groove, the pull plate is fixedly connected to the positioning block, a tension spring is provided inside the rectangular groove, and the end of the tension spring is fixedly connected to the pull plate.

[0009] In a preferred embodiment of this utility model, the end of the positioning block near the operating space is provided with an arc-shaped surface, and the surface of the swing arm near the positioning block is provided with a positioning groove, which corresponds to the positioning block.

[0010] In a preferred embodiment of this utility model, the pull plate is normally fully housed in the rectangular groove, while the positioning block is inserted into the toolbox.

[0011] As a preferred embodiment of this utility model, a spline groove is provided at the top of the lifting column, and the lifting column is connected to a support platform adapted to the shape of the fire detection element through the spline groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting mechanism driven by the cam enables one-click lifting of the fire detection component, eliminating the need for fingers to insert into the tight component slots for digging, thus avoiding nail damage and damage to the component's precision parts due to uneven force during digging. At the same time, the lifting column is connected to a customized support platform through a spline groove. The support platform is precisely adapted to the shape of the component, which can evenly support the bottom of the component, avoiding scratches and stress concentration problems caused by general flat-head lifting. This provides secondary protection for expensive precision components. Furthermore, the spring at the bottom of the toolbox stores elastic potential energy when the cam rotates. After the component is removed, it can automatically drive the cam to rotate in the opposite direction, driving the swing arm to reset. Simultaneously, the lifting plate automatically descends and returns to the storage state under the action of gravity, eliminating the need to manually push back the lifting components and simplifying the operation process.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0018] Reference Figure 1-7 This is an embodiment of the present invention, which provides a fire detection device that is easy to install and store, including a toolbox 1. The toolbox 1 has a protective plate 2 inside. The surface of the protective plate 2 has multiple component slots 3. The shape of the component slots 3 is the same as that of the fire detection component. A lifting mechanism is provided below the protective plate 2. The lifting mechanism includes a lifting plate 4. A limiting groove 5 is provided on the inner wall of the toolbox 1. The end of the lifting plate 4 is movably engaged in the limiting groove 5. Multiple lifting columns 6 are provided on the surface of the lifting plate 4. The number of lifting columns 6 matches the number of component slots 3, and the lifting columns 6 are located directly below the component slots 3. A cam 7 is provided below the lifting plate 4. The end of the cam 7 is connected to the inner wall of the toolbox 1 through a rotating shaft. An operating component is provided on the side of the cam 7.

[0019] When in use, the fire detection element is placed in the element slot 3 of the protective plate 2. At this time, the protruding part of the cam 7 does not act on the lifting plate 4. The lifting plate 4 is located at the bottom of the toolbox 1. The lifting column 6 is completely hidden under the element slot 3. The fire detection element is securely clamped and protected. When it is necessary to remove the element, the user rotates the shaft through the operating component, which in turn drives the cam 7 to rotate. During the rotation, the protruding contour of the cam 7 gradually contacts the lower surface of the lifting plate 4 and applies an upward thrust. Under the push of the cam 7, the lifting plate 4 begins to move upward in a straight line along the guide of the limiting groove 5. The lifting column 6 fixed on the lifting plate 4 rises synchronously and is precisely inserted into the upper element slot 3, and the fire detection element is smoothly lifted upward from the bottom.

[0020] In summary, the lifting mechanism enables one-click lifting of fire detection components, facilitating easy placement and removal. Users no longer need to painstakingly insert their fingers into the tight component slots 3 to pry out the components, which is especially beneficial for small and precise detection components, preventing damage to the components from fingernails.

[0021] Furthermore, the operating component includes a swing arm 9, the bottom end of which is fixedly sleeved on the rotating shaft surface at the end of the cam 7. An operating space is provided inside the toolbox 1 and on one side of the protective plate 2, and the swing arm 9 is movably arranged in the operating space.

[0022] In use, the swing arm 9 is normally located at the bottom of the operating space. At this time, the rotating shaft fixedly connected to it drives the cam 7 to an angle that will not lift the lifting plate 4. The entire mechanism is in a stable state, and the component is properly stored. When the user needs to take out the component, he will lift the top of the swing arm 9 with his fingers. Since the bottom end of the swing arm 9 is fixedly sleeved on the rotating shaft, this pushing force forms a lever effect, forcing the rotating shaft to start rotating. This directly drives the cam 7 fixed at the other end of it to rotate synchronously. The protruding part of the cam 7 gradually faces and contacts the lower surface of the lifting plate 4 as it rotates, and begins to perform the lifting action we discussed earlier. Finally, the component is lifted by the lifting column 6.

[0023] Furthermore, a spring 8 is provided at the bottom of the toolbox 1, and the top of the spring 8 is connected to a cam 7.

[0024] When in use, when the user pushes the swing arm 9 upward to lift the component, the swing arm 9 drives the rotating shaft and cam 7 to rotate. This rotation will twist the spring 8 located at the bottom, causing the spring 8 to deform and store elastic potential energy. When the user removes the component, the twisted spring 8 will immediately release its stored elastic potential energy, generating a reverse torque that drives the cam 7 to rotate in the opposite direction. The reverse rotation of the cam 7 directly drives the swing arm 9 to automatically and smoothly swing back to its initial position. At the same time, after losing the support of the cam 7, the lifting plate 4 descends under the action of gravity, and the entire device returns to its stored state.

[0025] Furthermore, a positioning block 10 is provided through the toolbox 1 on the side near the operating space. A rectangular groove 11 is provided on the outer side of the toolbox 1. A pull plate 12 is movably provided inside the rectangular groove 11. The pull plate 12 is fixedly connected to the positioning block 10. A tension spring 13 is provided inside the rectangular groove 11. The end of the tension spring 13 is fixedly connected to the pull plate 12. An arc-shaped surface is provided at the end of the positioning block 10 near the operating space. A positioning groove is provided on the surface of the swing arm 9 near the positioning block 10. The positioning groove corresponds to the positioning block 10.

[0026] In use, under the tension of the tension spring 13, the positioning block 10 is inserted into the operating space. When the swing arm 9 swings upward, the side of the swing arm 9 will first contact the arc surface of the positioning block 10. The arc surface acts as a guide surface. Under the squeezing force of the swing arm 9 on the arc surface of the positioning block 10, the positioning block 10 will overcome the elastic force of the tension spring 13 and push the positioning block 10 to the outside of the toolbox 1 until the positioning block 10 is in a vertical state. Then, the head of the positioning block 10 will slide into the positioning groove on the surface of the swing arm 9 due to the elastic force of the tension spring 13, thereby achieving the vertical positioning of the swing arm 9. When unlocking is required, the user pulls the pull plate 12 outward to overcome the tension of the tension spring 13. The positioning block 10 will vertically exit from the positioning groove of the swing arm 9, releasing the rotation restriction on the swing arm 9. Under the torque of the spring 8, the swing arm 9 will automatically swing back to the initial position.

[0027] Furthermore, the pull plate 12 is completely retracted into the rectangular slot 11 under normal conditions, while the positioning block 10 is inserted into the toolbox 1.

[0028] When in use, there are no protruding parts on the outside of the toolbox 1, and the pull plate 12 is flush with the outer surface of the toolbox 1, resulting in a neat and smooth appearance, which avoids possible snagging, bumping or damage to exposed parts during transportation.

[0029] Furthermore, a spline groove 14 is provided at the top of the lifting column 6, and the lifting column 6 is connected to a support platform adapted to the shape of the fire detection element through the spline groove 14.

[0030] During use, all lifting columns 6 have a spline groove 14 machined at the top. Correspondingly, a support platform is specially designed for each fire detection element of different shape and size. The bottom of this support platform has a spline shaft, the shape and size of which are perfectly matched with the spline groove 14 on the lifting column 6. The customized support platform ensures that the bottom of the element is evenly stressed and fits well, avoiding the problems of scratches, stress concentration or unstable support that may be caused by the general flat-head lifting column 6. It plays a secondary protection role for the precision and expensive detection elements.
