Description

Technical Field

[0001] This utility model relates to the field of armored door technology, specifically to a pearl cotton-filled shock-resistant armored door buffer structure. Background Technology

[0002] The core structure of the armored door is a robust steel structure, with high-strength metal plates in the middle of the door leaf. The interior can be filled with materials such as pearl cotton, honeycomb paper, water-foamed material, and aluminum honeycomb.

[0003] For example, the announcement number CN209483129U, entitled "A Buffered Soundproof Armored Door," includes a door frame and a door leaf located inside the door frame. One side of the door leaf is hinged to the door frame via a hinge. The door leaf includes two oppositely parallel and vertically placed door stiles. Thus, in this application, by using a pool plate with a layered structure and steel plate layers sandwiched on both sides of the foamed aluminum board layer, while achieving security and anti-theft, the armored door also has a soundproofing effect due to the buffering, vibration reduction, and sound insulation properties of the foamed aluminum board layer itself. Furthermore, because foamed aluminum itself is lightweight, the resulting armored door is lighter than other types of armored doors, which can reduce the impact between the door frame due to the inertia of the door leaf during the opening and closing process.

[0004] Although the existing armored doors have a buffer structure, the buffer structure still has the following problems: 1. There is no buffer structure at the outer edge of the buffer groove, and the impact of the door body is prone to generate noise; 2. The buffer components in the buffer groove are easily jammed by the limiting components, making the buffer components unusable. Therefore, it does not meet the current requirements. In response, a pearl cotton-filled shock-resistant armored door buffer structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a pearl cotton-filled shockproof armor door buffer structure to solve the problems mentioned in the background art, such as the outer edge of the existing buffer structure easily touching the door body and generating noise, and the buffer component easily getting stuck and affecting secondary use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pearl cotton-filled shock-resistant armored door buffer structure, comprising: a door body, wherein a door sleeve is installed at the front end of the door body; and further comprising:

[0007] A buffer assembly is installed on the outer wall of the door frame that contacts the door body. The buffer assembly includes a limiting buffer groove, and a buffer plate is provided at the opening of the limiting buffer groove.

[0008] A buffer assembly is installed in the limiting buffer groove. Multiple buffer assemblies are arranged laterally at intervals. Each buffer assembly includes a buffer cylinder, a buffer rod extending to the outside is installed inside the buffer cylinder, a return spring is installed between the buffer rod and the buffer cylinder, and a top plate is installed at the end of the buffer rod. The top plate is connected to the rear end face of the buffer plate by bolts.

[0009] Preferably, a plurality of protruding first rubber blocks are installed on the outer wall of the rear end face of the buffer plate.

[0010] Preferably, a rubber pad is installed on the outer wall of the front end face of the buffer plate.

[0011] Preferably, the buffer cylinder has an inlet and outlet at its end, and the lower end of the buffer rod is provided with a limit frame, the size of which is larger than the inlet and outlet.

[0012] Preferably, a second rubber block is installed at the lower bottom of the limiting frame.

[0013] Preferably, a limiting base plate is provided at the inner bottom of the buffer cylinder.

[0014] Preferably, the inner wall of the buffer cylinder is provided with a sliding groove, and a slider is installed in the sliding groove. The slider is connected to the limiting frame by bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) In this utility model, multiple sets of horizontally spaced buffer components are used to buffer the impact generated when the door closes and reduce the noise generated when closing. Specifically, when closing, the impact generated by the door causes the buffer plate to move closer to the limiting buffer groove. The impact force causes the buffer rod to retract into the buffer cylinder and applies pressure to the return spring, compressing the return spring. After opening the door, the door no longer applies pressure, causing the return spring to return and rebound, driving the top plate and buffer rod to extend forward, so that the buffer plate returns to its original position, achieving the buffering effect. The above structure has a larger buffering range, and the impact force can be distributed to each horizontally arranged buffer component. The buffer components are also not easy to get stuck, making it easy to use.

[0017] (2) In this utility model, when the buffer plate contacts the surface of the limiting buffer groove, the first rubber block will contact the limiting buffer groove first, so that the sound and impact generated by the buffer plate contacting the surface of the limiting buffer groove are smaller. The rubber pad on the surface of the buffer plate contacts the door body, so that the door body will not directly contact the buffer plate, thus reducing the impact and noise generated by the surface contact. This solves the problem that the outer edge of the buffer groove does not have a buffer structure, and the door body is prone to noise when it is impacted.

[0018] (3) In this utility model, when the buffer rod moves in and out of the buffer cylinder, the size of the limiting frame is larger than that of the inlet and outlet, so as to prevent the buffer rod from separating from the buffer cylinder at the inlet and outlet during the reciprocating in and out process. In addition, the setting of the slider and the slide groove can improve the smoothness and smoothness of the displacement of the buffer rod during the buffering process, making it less likely to get stuck. When the buffer rod is pressed down and retracted into the buffer cylinder under force, the second rubber block at its bottom will contact the limiting base plate first, which can reduce the impact force at that point and reduce the noise generated at that point.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides an embodiment of a pearl cotton-filled shock-resistant armored door buffer structure, comprising: a door body 1, with a door sleeve 101 installed at the front end of the door body 1; further comprising: a buffer assembly 2, which is installed on the outer wall of the door sleeve 101 in contact with the door body 1, the buffer assembly 2 including a limiting buffer groove 201, and a buffer plate 202 provided at the opening of the limiting buffer groove 201; and a buffer component 3, which is installed in the limiting buffer groove 201, with multiple buffer components 3 arranged laterally at intervals, each buffer component 3 including a buffer cylinder 301, with a buffer rod 302 extending to the outside installed inside the buffer cylinder 301, and a return spring 303 installed between the buffer rod 302 and the buffer cylinder 301. A top plate 304 is installed at the end of 02. The top plate 304 is connected to the rear end face of the buffer plate 202 by bolts. Multiple sets of horizontally spaced buffer components 3 buffer the impact generated when the door 1 closes and reduce the noise generated when closing. Specifically, when closing, the impact generated by the door 1 drives the buffer plate 202 to approach the limit buffer groove 201. The impact force causes the buffer rod 302 to retract into the buffer cylinder 301 and applies pressure to the return spring 303, compressing the return spring 303. After the door is opened, the door 1 no longer applies pressure, causing the return spring 303 to return to its original position and rebound, driving the top plate 304 and the buffer rod 302 to extend forward, so that the buffer plate 202 returns to its original position, thus achieving the buffering effect.

[0026] Furthermore, such as Figure 3 As shown, multiple protruding first rubber blocks 203 are installed on the outer wall of the rear end face of the buffer plate 202, and rubber pads 204 are installed on the outer wall of the front end face of the buffer plate 202. When the buffer plate 202 contacts the surface of the limiting buffer groove 201, the first rubber blocks 203 will contact the limiting buffer groove 201 first, so that the sound and impact generated by the buffer plate 202 contacting the surface of the limiting buffer groove 201 are smaller. The rubber pads 204 on the surface of the buffer plate 202 then contact the door body 1, so that the door body 1 will not directly contact the buffer plate 202, thus reducing the impact and noise generated by the surface contact.

[0027] Please see Figure 4 The buffer cylinder 301 has an inlet and outlet 305 at its end. The lower end of the buffer rod 302 is provided with a limit frame 306. The size of the limit frame 306 is larger than that of the inlet and outlet 305. The inner wall of the buffer cylinder 301 is provided with a sliding groove 308. A slider 307 is installed in the sliding groove 308. The slider 307 is connected to the limit frame 306 by bolts. A second rubber block 309 is installed at the lower bottom of the limit frame 306. The inner bottom of the buffer cylinder 301 is provided with a limit base plate 310.

[0028] When the buffer rod 302 moves in and out of the buffer cylinder 301, the size of the limiting frame 306 is larger than that of the inlet and outlet 305, which prevents the buffer rod 302 from detaching from the buffer cylinder 301 at the inlet and outlet 305 during the reciprocating movement. In addition, the sliding block 307 and the sliding groove 308 can improve the smoothness and fluidity of the displacement of the buffer rod 302 during the buffering process, making it less likely to get stuck. When the buffer rod 302 is pressed down and retracts into the buffer cylinder 301 under force, the second rubber block 309 at its bottom will contact the limiting base plate 310 first, which can reduce the impact force at that point and reduce the noise generated there.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
