Description

Technical Field

[0001] This utility model relates to the field of explosion-proof retrofitting engineering technology, specifically to a protective plate structure for explosion-proof retrofitting engineering that is easy to assemble. Background Technology

[0002] Explosion-proof retrofitting projects use protective plates to enhance the explosion and impact resistance of engineering facilities, ensure the safety of engineering structures in major disasters, and reduce post-disaster losses.

[0003] Publication number CN221989958U discloses a protective plate for construction engineering. When an object falls from a height, it lands on a second protective plate. The falling force causes the second protective plate to rotate via a second connecting shaft, compressing a spring. The spring tension, combined with a rubber plate, provides a cushioning effect, allowing the object to fall close to the wall. The first protective plate, tilted and close to the wall, guides the falling object to roll onto the rubber plate. A torsion spring ensures the first protective plate remains in contact with the wall. The angle of the first connecting seat is determined, and the threaded rod is rotated to adjust the support length. A pin is then fixed to the ground to support the height of the protective plate body. A connector block is inserted into the connector slot and secured with bolts. This allows two protective plates to be joined together. However, this patent has the following problems in practical use:

[0004] Although this type of protective plate for building engineering inserts the plug into the plug slot and then fixes it with bolts, allowing two protective plate bodies to be spliced ​​together, the bolts are prone to stripping after frequent use, making it inconvenient for the next assembly and use of the protective plate.

[0005] A protective plate structure for explosion-proof retrofitting projects that is easy to assemble is proposed to solve the problems mentioned above. Utility Model Content

However, the bolts are prone to stripping after frequent use, which makes it inconvenient for the next assembly and use of the protective plate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective plate structure for explosion-proof retrofitting projects that is easy to assemble, including a splicing mechanism and a retaining spring installed inside;

[0008] A limiting mechanism is provided on one side of the splicing mechanism, and one side of the limiting mechanism is fixedly connected to one side of the connecting column.

[0009] Also includes:

[0010] The splicing mechanism includes a connecting column, and a protective plate body is slidably connected to both sides inside the connecting column;

[0011] Among them, a baffle is engaged with the upper part of the connecting post near the main body of the guard plate, and a connecting sleeve is threadedly connected to the center of the baffle;

[0012] The connecting sleeve has a movable block slidably connected to the center position inside. The outer side of one end of the movable block is engaged with a retaining spring, and a button is attached to the outer side of the retaining spring.

[0013] Preferably, the outer side of the button is slidably connected to the connecting sleeve, the inner side of the button is slidably connected to the movable block, and a first spring is fixedly connected to one end of the button, with one end of the first spring fixedly connected to the movable block.

[0014] Preferably, a first steel ball is symmetrically attached to the outer side of one end of the button, one side of the two first steel balls is attached to the movable block, and a fixing ring is attached to the other side of the first steel ball. The outer side of the fixing ring is fixedly connected to the connecting sleeve.

[0015] Preferably, a second spring is sleeved on the outer side of the movable block near the fixed ring, and a groove is formed inside the movable block at the end away from the button. Two second steel balls are symmetrically slidably connected to both sides inside the groove. One side of the two second steel balls is fitted and connected to the connecting sleeve, and a snap-fit ​​block is fitted and connected to the other side of the second steel balls. One end of the snap-fit ​​block is fixedly connected to the main body of the guard plate.

[0016] Preferably, the limiting mechanism includes a fixing block, one end of which is fixedly connected to the connecting column, and the other end of which is rotatably connected to a threaded sleeve.

[0017] Preferably, the threaded sleeve has an internal threaded connection to a threaded rod, one side of which is fitted with a first clamping block, one side of which is fixedly connected to a connecting post, and one end of which is rotatably connected to a connecting rod.

[0018] Preferably, one end of the connecting rod is rotatably connected to a second clamping block, the inner side of the second clamping block is in contact with the threaded rod, and the end of the first clamping block away from the connecting rod is rotatably connected to a stud, one end of the stud being in contact with the second clamping block.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this easy-to-assemble protective plate structure for explosion-proof retrofitting projects allows for quick assembly and disassembly of the protective plate body without the use of any tools through the splicing mechanism, and the limiting mechanism provides support for the protective plate body, improving the stability of the device. The specific details are as follows:

[0020] 1. By setting up a splicing mechanism, the main body of the protective plate can be quickly assembled and disassembled without the use of any tools. Utilizing the interlocking relationship between the connecting column and the main body of the protective plate, the lateral movement of the main body of the protective plate can be limited. Utilizing the baffle to limit the height of the main body of the protective plate, the assembly and splicing of the main body of the protective plate can be completed quickly. By pressing the button, the first spring and the second spring are compressed. At the same time, the button pushes the first steel ball towards the fixed ring. Utilizing the fixed ring to limit the first steel ball, and utilizing the cooperation between the first steel ball, the movable block, the fixed ring, and the button, the movable block can be moved outward within the connecting sleeve, thereby releasing the limiting effect of the connecting sleeve on the second steel ball. This allows the interlocking block to disengage from the second steel ball. Utilizing the threaded action between the connecting sleeve and the baffle, the connecting sleeve can be removed from the baffle, thereby releasing the limiting effect of the baffle on the main body of the protective plate, thus realizing the disassembly of the main body of the protective plate.

[0021] 2. By setting a limiting mechanism, the guard plate body can be supported, improving the stability of the device. The threaded action between the threaded sleeve and the threaded rod can be used to adjust the length of the threaded rod extension. At the same time, the threaded sleeve rotates around the connecting block, so that the bottom block contacts the ground to support the connecting column. The cooperation between the first clamping block, the second clamping block and the stud can limit the position of the threaded rod in the retracted state, preventing the threaded rod from moving when the device is not in use and causing wear on the threaded rod.

[0034] A first steel ball 109 is symmetrically attached to the outer side of one end of the button 107. One side of the two first steel balls 109 is attached to the movable block 105. A fixing ring 110 is attached to the other side of the first steel ball 109. The outer side of the fixing ring 110 is fixedly connected to the connecting sleeve 104. The position of the first steel ball 109 can be limited by setting the fixing ring 110.

[0035] A second spring 111 is sleeved on the outer side of the movable block 105 near the fixed ring 110. A groove 112 is opened in the interior of the movable block 105 away from the button 107.
