Description

Technical Field

[0001] The present application relates to the technical field of smoke and temperature sensor disassembly, and in particular to a telescopic disassembly structure of a smoke and temperature sensor device. Background Art

[0002] In the field of fire protection, smoke and temperature detectors are an effective means of preventing fires. They achieve fire prevention by monitoring smoke concentration and temperature. They are widely used in public places such as subways, hotels, teaching buildings, and office buildings, and are mostly fixedly installed on the top of the detected space. Smoke and temperature detectors need to be maintained and inspected frequently during use, so they need to be disassembled using a smoke and temperature sensor disassembler.

[0003] When in use, the open side of the mounting base is placed on the smoke and temperature detector, and the smoke and temperature detector can be installed and removed by rotating the support tube. However, due to the different models of smoke and temperature detectors on the market, and the diameters of the smoke and temperature detectors are not exactly the same, and the bowl-shaped disassembly and assembly tools on the market cannot be adjusted according to the diameter of the smoke and temperature detectors, resulting in poor applicability of the smoke sensor disassembler. A Chinese patent (Announcement No.: CN218428062U) discloses a universal telescopic rod smoke sensor disassembler that can disassemble and assemble smoke and temperature sensors of different diameters.

[0004] In the above document, the adjusting block is pressed into the adjusting tube to make the adjusting tube slide in the supporting tube so as to be able to shrink or extend the overall length of the remover. However, the user needs to insert his fingers into the through hole to push the adjusting block to move. It is easy for the user's fingers to get stuck in the through hole, which makes it inconvenient to adjust the telescopic adjustment of the remover. Moreover, the user's fingers no longer squeeze the adjusting block, and the spring is no longer squeezed by pressure to push the adjusting block to reset. It is easy for the user to move the adjusting block into the through hole before adjusting the overall length of the remover, which also makes it inconvenient to adjust the telescopic adjustment of the remover. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a telescopic disassembly structure for a smoke temperature sensor device, which has the advantages of easy telescopic adjustment and solves the problem of inconvenient telescopic adjustment.

[0006] To achieve the above objectives, the present application provides the following technical solutions: a telescopic disassembly structure for a smoke temperature sensor device, comprising a disassembly device body, the disassembly device body comprising a disassembly head body, a support rod, and a telescopic rod, wherein sliding blocks are fixed to both left and right ends of the telescopic rod, and a positioning structure is provided on the left side of the telescopic rod;

[0007] The positioning structure includes a connecting block, a vertical plate, a positioning block fixedly installed on the right side wall of the vertical plate, an operating block fixedly installed on the left side wall of the vertical plate, a T-shaped slider at the top of the vertical plate and a resistance structure fixedly installed on the left side wall of the vertical plate for resisting it.

[0008] The above technical solution can reduce the phenomenon of the user's fingers getting stuck in the support rod, and can also reduce the phenomenon of the positioning block moving into the positioning groove before the overall length of the disassembler body is adjusted, thereby effectively improving the convenience of the disassembler body when being telescopically adjusted.

[0009] Furthermore, a plurality of positioning slots for positioning blocks to be located inside the left side wall of the telescopic rod are provided, and the positioning blocks are inserted into the positioning slots.

[0010] By adopting the above technical solution, the positioning block is moved into the positioning groove of the telescopic rod so as to fix the support rod to the surface of the telescopic rod.

[0011] Furthermore, a semi-arc groove is provided on the right side of the connecting block, and the support rod is located inside the semi-arc groove and fixed thereto.

[0012] By adopting the above technical solution, the connecting block can be tightly fitted to the outer side of the support rod through the semi-arc groove.

[0013] Furthermore, a long hole is provided at the top of the connecting block for the vertical plate to pass through, and the vertical plate is slidably connected to the inner side of the long hole.

[0014] By adopting the above technical solution, the vertical plate can pass through the interior of the connecting block through the long hole, so that the vertical plate can be connected to the resistance structure located inside the connecting block, so that the resistance structure can act as a resistance to the positioning block through the vertical plate, making it difficult for the positioning block to move in or out of the positioning groove at will due to inertia.

[0015] Furthermore, a T-shaped slot is provided on the top wall of the inner cavity of the connection block, and the T-shaped sliding block is located inside the T-shaped slot and is slidably connected thereto.

[0016] By adopting the above technical solution, the vertical plate can be stably moved in the connecting block through the T-shaped slider, and the vertical plate is not likely to fall out of the connecting block through the T-shaped slider.

[0017] Furthermore, the resistance structure includes two hinged rods hingedly connected to the left side wall of the vertical plate, the other ends of the two hinged rods are hingedly connected to a pressure block, the internal sliding connection of the pressure block is connected to a sleeve rod, the outer surfaces of the two sleeve rods are sleeved with resistance springs, and the opposite ends of the two pressure blocks are fixed with rubber blocks.

[0018] The above technical solution can provide resistance to the positioning block inserted into the positioning slot of the telescopic rod, thereby preventing the positioning block from moving out of or into the positioning slot at will, thereby causing unstable telescopic adjustment of the disassembler body.

[0019] Furthermore, the opposite ends of the front and rear sleeve rods are respectively fixed to the front and rear walls of the inner cavity of the connecting block, and the opposite walls of the front and rear pressure blocks are each provided with a circular hole for the sleeve rod to pass through.

[0020] By adopting the above technical solution, the pressing block can slide on the surface of the sleeve rod.

[0021] Furthermore, the opposite walls of the front and rear rubber blocks are each provided with a through hole for the sleeve rod to pass through, and the through hole corresponds to the circular hole.

[0022] By adopting the above technical solution, when the pressing block slides on the outer surface of the sleeve rod, the rubber block can also slide on the outer surface of the sleeve rod, avoiding the rubber block from hindering the sliding of the pressing block on the sleeve rod surface and reducing the moving distance of the pressing block on the sleeve rod surface.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The telescopic disassembly structure of the smoke temperature sensor device is provided with a positioning structure, which can reduce the phenomenon of the user's fingers being stuck in the support rod, and can also reduce the phenomenon of the positioning block moving into the positioning groove before the overall length of the disassembler body is adjusted. This can effectively improve the convenience of the disassembler body during telescopic adjustment, and the operation is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] See also Figures 1 to 2 The telescopic disassembly structure of the smoke temperature sensor device in this embodiment includes a disassembly device body 1, which includes a disassembly head body 11, a support rod 12 and a telescopic rod 13. Sliding blocks 2 are fixed at both ends of the telescopic rod 13, and a positioning structure is provided on the left side of the telescopic rod 13.

[0032] In addition, a threaded barrel is fixed to the lower end of the disassembly head body 11, and the threaded barrel is threadedly connected to the outer surface of the top end of the support rod 12 so that the disassembly head body 11 can be installed at the top end of the support rod 12, and the threaded barrel is cylindrical with a hollow interior and missing both ends of the upper end.

[0033] In addition, a through hole is provided on the wall opposite to the disassembly head body 11 and the support rod 12. The support rod 12 is a cylindrical shape with a hollow interior and a missing lower end, and the telescopic rod 13 is a cylindrical shape with a hollow interior and a missing upper end, so that the disassembly head body 11, the support rod 12 and the telescopic rod 13 are connected.

[0034] In addition, both the left and right walls of the inner cavity of the support rod 12 are provided with limiting grooves, and the sliding block 2 is slidably connected to the inside of the limiting grooves, so that the telescopic rod 13 is not easily separated from the support rod 12 when it moves in or out of the support rod 12.

[0035] See also Figure 1 、 Figure 3 and Figure 4 The positioning structure in this embodiment includes a connecting block 31, a vertical plate 33, a positioning block 32 fixedly installed on the right side wall of the vertical plate 33, an operating block 34 fixedly installed on the left side wall of the vertical plate 33, a T-shaped slider 35 at the top of the vertical plate 33 and a resistance structure fixedly installed on the left side wall of the vertical plate 33 for resisting it.

[0036] Among them, the left side wall of the telescopic rod 13 is provided with a plurality of positioning grooves for the positioning block 32 to be located therein, and the positioning block 32 is inserted into the interior of the positioning groove. The positioning block 32 is moved into the positioning groove of the telescopic rod 13 so that the support rod 12 can be fixed to the surface of the telescopic rod 13, and the positioning block 32 is inserted into the positioning grooves at different positions and heights so that the support rod 12 can be fixed at different positions and heights on the surface of the telescopic rod 13 according to the overall length of the required disassembler body 1.

[0037] In addition, a semi-arc groove is opened on the right side of the connecting block 31, and the support rod 12 is located inside the semi-arc groove and fixed thereto. The connecting block 31 can fit tightly against the outer side of the support rod 12 through the semi-arc groove, so that the connecting block 31 can be tightly fixed to the surface of the support rod 12.

[0038] In addition, a long hole is provided at the top of the connecting block 31 for the vertical plate 33 to pass through. The vertical plate 33 is slidably connected to the inner side of the long hole. The vertical plate 33 can pass through the interior of the connecting block 31 through the long hole, so that the vertical plate 33 can be connected to the resistance structure located inside the connecting block 31, so that the resistance structure can act as a resistance to the positioning block 32 through the vertical plate 33, making it difficult for the positioning block 32 to move in or out of the positioning groove at will due to inertia, thereby ensuring that the support rod 12 can be stably fixed on the surface of the telescopic rod 13.

[0039] In addition, a T-shaped groove is provided on the top wall of the inner cavity of the connecting block 31, and the T-shaped slider 35 is located inside the T-shaped groove and is slidably connected to it. The T-shaped slider 35 can slide on the top wall of the inner cavity of the connecting block 31 through the T-shaped groove, so that the vertical plate 33 can move stably in the connecting block 31 through the T-shaped slider 35, and the vertical plate 33 is not easy to fall out of the connecting block 31 through the T-shaped slider 35.

[0040] Furthermore, the operating block 34 is T-shaped so as to increase the contact area for the user during operation.

[0041] See also Figure 4 The resistance structure in this embodiment includes two hinged rods 36 hingedly connected to the left side wall of the vertical plate 33. The other ends of the two hinged rods 36 are hingedly connected to a pressure block 37. The inner sliding connection of the pressure block 37 is a sleeve rod 38. The outer surfaces of the two sleeve rods 38 are sleeved with resistance springs 39. Rubber blocks 310 are fixed to the opposite ends of the two pressure blocks 37 to prevent the two pressure blocks 37 from being damaged due to collision when the two resistance springs 39 push the two pressure blocks 37 to move relative to each other.

[0042] Secondly, the opposite ends of the front and rear sleeve rods 38 are respectively fixed to the front and rear walls of the inner cavity of the connecting block 31, and the opposite walls of the front and rear pressure blocks 37 are each provided with a circular hole for the sleeve rod 38 to pass through the interior, so that the pressure block 37 can slide on the outer surface of the sleeve rod 38 through the circular hole, so that the sleeve rod 38 can support the pressure block 37 and the resistance spring 39, and can limit the movement range of the pressure block 37 in the connecting block 31.

[0043] At the same time, the opposite walls of the front and rear rubber blocks 310 are each provided with a through hole for the sleeve rod 38 to pass through. The through hole corresponds to the circular hole, so that when the pressure block 37 slides on the outer surface of the sleeve rod 38, the rubber block 310 can also slide on the outer surface of the sleeve rod 38, avoiding the rubber block 310 from obstructing the sliding of the pressure block 37 on the surface of the sleeve rod 38, thereby reducing the moving distance of the pressure block 37 on the surface of the sleeve rod 38.

[0044] The working principle of the above embodiment is:

[0045] When in use, when it is necessary to extend or shorten the overall length of the disassembler body 1, the user pulls the operating block 34 to the left, so that the operating block 34 drives the vertical plate 33 to move. When the vertical plate 33 moves, it squeezes the two hinged rods 36, thereby squeezing the two hinged rods 36 into a tilted shape. When the two hinged rods 36 gradually tilt, they push the front and rear pressure blocks 37 to move back to each other, so that the distance between the two pressure blocks 37 gradually increases. The pressure blocks 37 also squeeze the resistance spring 39. When the vertical plate 33 moves to the left, it can drive the positioning block 32 to move out of the positioning groove of the telescopic rod 13. When the user drives the operating block 34 to move up and down, the operating block 34 can drive the support rod 12 to move on the surface of the telescopic rod 13 through the connecting block 31.

[0046] When the support rod 12 moves to the desired height, the user can release the operating block 34, so that the vertical plate 33 no longer has pressure on the two hinge rods 36, and the two hinge rods 36 no longer squeeze the resistance spring 39 through the pressure block 37, so that the two resistance springs 39 are no longer squeezed by pressure and push the two pressure blocks 37 relative to each other under the action of their own elastic force. When the two pressure blocks 37 move, they can drive the two hinge rods 36 to gradually move from the inclined state to the vertical state, that is, the two hinge rods 36 push the vertical plate 33 to move right, so that the vertical plate 33 can drive the positioning block 32 to move into the positioning groove of the corresponding height of the telescopic rod 13, thereby fixing the support rod 12 on the surface of the telescopic rod 13, which can effectively improve the convenience of the detacher body 1 when extending and retracting, and can reduce the phenomenon that the user's fingers are stuck in the support rod 12, and can also reduce the phenomenon that the positioning block 32 moves into the positioning groove before the overall length of the detacher body 1 is adjusted.
