Technical Field

[0001] This utility model relates to the field of fire sequencer technology, and in particular to a fire sequencer installation structure for a steel insulated fire door. Background Technology

[0002] A fire door sequencer, also known as a fire door sequencer or locator, is a device specifically designed to control the closing sequence of fire doors. It is mainly installed on double or multi-leaf fire doors and its function is to ensure that fire doors close in a preset order, thereby preventing gaps caused by improper closing sequence, which would affect the fireproof and smoke-proof functions of the fire doors.

[0003] Most fire sequencers on the market currently use bolt fixing. This method requires aligning each bolt hole and tightening the bolts one by one, which is quite cumbersome. Once the fire sequencer malfunctions, it usually requires disassembling the entire door or a large number of bolts. This not only increases the difficulty of maintenance but also increases the cost. Frequent disassembly will cause wear on the threads of the bolts or the fire sequencer itself, thus affecting the firmness after reinstallation. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the above-mentioned equipment is difficult to disassemble due to the use of bolts for fixing, and thus proposes a fire-prevention sequencer installation structure for steel insulated fire doors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire-resistant sequencer installation structure for a steel insulated fire door, including a quick-release mechanism, wherein an adjustment mechanism is movably embedded in the inner surface wall of the quick-release mechanism;

[0006] The quick-release mechanism includes a sequencer body, a connecting arm inside the sequencer body, a set of shaft holes at the top of the connecting arm, a rotating shaft movably fitted between the inner surfaces of the set of shaft holes, a roller fixedly fitted on the outer surface of the rotating shaft, three sliding grooves on one side of the outer wall of the sequencer body, a movable groove at the top of the sequencer body, three sets of slots at the bottom of the inner wall of the movable groove, push blocks movably inserted into the inner surfaces of the three sets of slots, a push plate fixedly installed between the tops of the three sets of push blocks, and the outer surface of the push plate movably inserted into the interior of the movable groove.

[0007] Preferably, three sets of springs are fixedly installed at the bottom of the push plate, and the bottoms of the three sets of springs are fixedly connected to the bottom of the inner wall of the movable groove.

[0008] Preferably, the adjustment mechanism includes a base plate, and three sliders are fixedly installed on one side of the outer wall of the base plate.

[0009] Preferably, each of the three sliders has a set of movable grooves on its outer wall, and a spring is fixedly installed on one side of the inner wall of each of the three movable grooves.

[0010] Preferably, each of the three sets of springs has a locking block fixedly installed on one side of its outer wall, and the outer walls of the three sets of locking blocks are movably inserted into the interior of the movable groove.

[0011] Preferably, two connecting plates are fixedly installed on the outer wall of the base plate, and a set of sliding grooves is provided on one side of the outer wall of each of the two connecting plates.

[0012] Preferably, the inner surface of both sets of sliding grooves is movably fitted with sliders, and the outer surface of both connecting plates is provided with two threaded holes.

[0013] Preferably, an adjusting plate is fixedly installed between the outer walls of the two sets of sliders, and a set of threaded holes is provided on the outer walls of the two adjusting plates.

[0014] Preferably, the inner surface of both sets of threaded holes 2 is threaded with fixing bolts, and the inner surface of each of the four threaded holes 1 is threaded with the outer surface of two of the fixing bolts in each set.

[0015] Preferably, the inner surface of each of the three sliding grooves is movably embedded in the outer surface of the slider, and the inner surface of each of the three sets of slots is movably inserted into the outer surface of the block.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, with the cooperation of the quick-release mechanism and the adjustment mechanism, during installation, simply insert the slider one into the slide groove one, and the locking block will automatically insert into the slot under the action of the spring two, achieving quick connection. When the sequencer is damaged, there is no need to disassemble the entire device or a large number of bolts. Just press the push plate, and the push block will push the locking block out of the slot, so the sequencer body can be easily removed without disassembling the base plate, which facilitates the replacement of vulnerable parts and ensures that the fire door can be restored to normal operation in a timely manner. This not only reduces maintenance time and workload and lowers maintenance costs, but also improves the efficiency of fire door use.

[0018] 2. In this utility model, by pulling the adjusting plate under the action of the adjusting mechanism, the slider two can be moved in the slide groove two, thereby realizing the adjustment of the fixed base length, so that the sequencer can adapt to door frames of different sizes and installation requirements, thus improving the versatility and applicability of the product.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as Figures 1-6As shown, this utility model provides a fire sequencer installation structure for a steel insulated fire door, including a quick-release mechanism 1, and an adjustment mechanism 2 is movably embedded in the inner surface wall of the quick-release mechanism 1.

[0031] The quick-release mechanism 1 includes a sequencer body 101. A connecting arm 102 is provided inside the sequencer body 101. A set of shaft holes 103 are opened at the top of the connecting arm 102. A rotating shaft 104 is movably sleeved between the inner surface walls of the set of shaft holes 103. A roller 105 is fixedly sleeved on the outer surface wall of the rotating shaft 104. Three sliding grooves 106 are opened on one side of the outer wall of the sequencer body 101. A movable groove 107 is opened at the top of the sequencer body 101. Three sets of slots 108 are opened at the bottom of the inner wall of the movable groove 107. Push blocks 109 are movably inserted into the inner surface walls of the three sets of slots 108. A push plate 110 is fixedly installed between the tops of the three sets of push blocks 109. The outer surface wall of the push plate 110 is movably inserted into the interior of the movable groove 107. Three sets of springs 111 are fixedly installed at the bottom of the push plate 110. The bottoms of the three sets of springs 111 are fixedly connected to the bottom of the inner wall of the movable groove 107.

[0032] The adjustment mechanism 2 includes a base plate 201. Three sliders 1 202 are fixedly installed on one side of the outer wall of the base plate 201. Each of the three sliders 1 202 has a set of movable grooves 203 on its outer wall. Each of the three movable grooves 203 has a spring 204 fixedly installed on one side of its inner wall. Each of the three springs 204 has a locking block 205 fixedly installed on one side of its outer wall. The outer walls of the three locking blocks 205 are movably inserted into the movable grooves 203.

[0033] The inner walls of the three sliding grooves 106 are movably embedded in the outer wall of the slider 202, and the inner walls of the three sets of slots 108 are movably inserted into the outer wall of the block 205.

[0034] The effect achieved by the entire embodiment 1 is that after the base plate 201 is fixed to the door frame, the sequencer body 101 can be connected to the base plate 201. Specifically, the slider 202 fixedly installed on the base plate 201 is inserted into the slide groove 106. When the locking block 205 installed inside the slider 202 contacts the inner wall of the slide groove 106, the top slope will be pushed, causing the locking block 205 to retract into the movable groove 203 and compress the spring 204. When the slider 202 is fully inserted into the slide groove 106, the sequencer continues to function. Then, at this time, the locking block 205 corresponds to the locking slot 108. Since the locking slot 108 is an "L"-shaped groove, the compressed spring 204 begins to extend, causing the locking block 205 to insert into the locking slot 108, thereby fixing the sequencer body 101 to the surface of the base plate 201. When the sequencer is used, if people close a corresponding door, that door will contact the middle of the connecting arm 102, causing the connecting arm 102 to rotate and eventually become parallel to the sequencer body 101, ensuring that the other door can be closed smoothly. If people close the door first... If the wrong door is opened, it will contact the roller 105 on the connecting arm 102. At this time, the sequencer body 101 and the connecting arm 102 will form a stable whole, thus blocking the door and preventing it from closing first. This ensures that the fire door can close in the prescribed order to achieve the fire separation effect. If the sequencer is damaged, people do not need to remove the base plate 201. They only need to press the push plate 110. At this time, the push plate 110 will descend inside the movable groove 107, which will not only start to compress the bottom spring 111, but also push the push block 109 to start. As the pusher descends inside the slot 108, when the bottom of the pusher 109 contacts the top inclined surface of the block 205, it pushes the block 205 out of the slot 108 and retracts into the movable slot 203. People only need to pull the sequencer body 101 out from the surface of the slider 202 to quickly disassemble the sequencer. This avoids the tedious process of disassembling the entire door or a large number of bolts, reduces maintenance difficulty, and saves maintenance time and costs. It also makes the replacement of some vulnerable parts more timely and convenient, which helps to maintain the normal operation of the fire door.

[0035] Example 2, as Figures 2-6As shown, the adjusting mechanism 2 includes a base plate 201. Three sliders 202 are fixedly installed on one side of the outer wall of the base plate 201. Each of the three sliders 202 has a set of movable grooves 203 on its outer wall. Each of the three movable grooves 203 has a spring 204 fixedly installed on one side of its inner wall. Each of the three springs 204 has a locking block 205 fixedly installed on one side of its outer wall. The outer walls of the three locking blocks 205 are movably inserted into the movable grooves 203. Two connecting plates 206 are fixedly installed on the outer wall of the base plate 201. Each side is provided with a set of sliding grooves 207. The inner surface of each set of sliding grooves 207 is movably fitted with a slider 208. The outer surface of each of the two connecting plates 206 is provided with two threaded holes 209. An adjusting plate 210 is fixedly installed between the outer surface of each set of sliders 208. The outer surface of each of the two adjusting plates 210 is provided with a set of threaded holes 211. The inner surface of each set of threaded holes 211 is threaded with a fixing bolt 212. The inner surface of each of the four threaded holes 209 is threaded with the outer surface of two of the fixing bolts 212 in each set.

[0036] The effect achieved by the entire embodiment 2 is that when the length of the fixed base needs to be adjusted, the user can directly pull the adjustment plate 210. At this time, the adjustment plate 210 will drive the slider 208 to move inside the slide groove 207, so that the adjustment plate 210 slides out from the side of the connecting plate 206. The two cooperate with each other, so that the sequencer can adapt to different installation environments. Then, the base plate 201 can be fixed with the help of the fixing bolt 212. In order to prevent the adjustment plate 210 from sliding again, the fixing bolt 212 can be screwed into the threaded hole 209 and the threaded hole 211 at the same time.

[0037] Working principle: When the length of the fixed base needs to be adjusted, the user can directly pull the adjusting plate 210. At this time, the adjusting plate 210 will drive the slider 208 to move within the slide groove 207, causing the adjusting plate 210 to slide out from one side of the connecting plate 206. The two work together to allow the sequencer to adapt to different installation environments. Subsequently, the base plate 201 can be fixed with the fixing bolts 212. To prevent the adjusting plate 210 from sliding again, the fixing bolts 212 can be screwed into both the first threaded hole 209 and the second threaded hole 211 simultaneously. After fixing the base plate 201 to the door frame, the... The sequencer body 101 is connected to the base plate 201. The specific operation is as follows: The slider 202 fixedly installed on the base plate 201 is inserted into the slide groove 106. When the locking block 205 installed inside the slider 202 contacts the inner wall of the slide groove 106, its top inclined surface is pushed by the inner wall, causing the locking block 205 to retract into the movable groove 203 and compress the spring 204. When the slider 202 is fully inserted into the slide groove 106, the locking block 205 corresponds to the position of the locking groove 108. Since the locking groove 108 is an "L" shaped groove, the compressed spring 204 begins to extend. The mechanism drives the locking block 205 to insert into the locking slot 108, thereby fixing the sequencer body 101 to the surface of the base plate 201. When the sequencer is in use, if people close a corresponding door, that door will contact the middle of the connecting arm 102, causing the connecting arm 102 to rotate until it is parallel to the sequencer body 101, ensuring that the other door can close smoothly. If people close the wrong door first, that door will contact the roller 105 on the connecting arm 102. At this time, the sequencer body 101 and the connecting arm 102 form a stable whole, thus holding the door in place and preventing it from closing first, ensuring that the fire door can close smoothly. When the sequencer is closed in the prescribed order, it achieves the effect of fireproof separation. If the sequencer is damaged, people do not need to disassemble the base plate 201. They only need to press the push plate 110. At this time, the push plate 110 will descend in the movable groove 107. It will not only start to squeeze the bottom spring 111, but also push the push block 109 to descend in the slot 108. When the bottom of the push block 109 contacts the top inclined surface of the slot 205, it will push the slot 205 to disengage from the slot 108 and retract into the movable groove 203. People only need to pull the sequencer body 101 out from the surface of the slider 202 to quickly disassemble the sequencer.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
