Description

Technical Field

[0001] The utility model belongs to the field of ceramic inserts, and particularly relates to a composite structure ceramic insert. Background Art

[0002] Composite structure bulletproof ceramics are an efficient bulletproof material, which simultaneously have the high hardness and toughness of ceramics and the energy absorption characteristics of conventional bulletproof materials. The inserts made of composite structure bulletproof ceramics have high-efficiency energy absorption and dispersion capabilities, as well as relatively low weight, thus being widely used.

[0003] The existing protection system based on bulletproof ceramic inserts includes several layers of insert functional layers. Each layer of insert functional layer further includes several functional areas. The several layers of insert functional layers and the several functional areas can be fixed by bolts and nuts, so as to achieve combined splicing and facilitate replacement and maintenance. However, after being impacted, the impact force is transmitted to the bolt connection, resulting in a decrease in the bolt fastening force, causing the bolts or nuts to loosen, thereby causing the connection instability between the insert functional layers and each functional area, and even causing the inserts to disperse when being impacted, ultimately affecting the structural stability of the entire protection system. Therefore, it is necessary to design a composite structure ceramic insert that can prevent bolts or nuts from loosening when being impacted. Summary of the Utility Model

[0025] Embodiment 1

[0026] As Figure 1 and Figure 2As shown in the figure, this embodiment provides a composite structure ceramic insert plate, which includes: a bulletproof plate 1, a side edge 2, a connecting block 3, a linkage bolt 4, a fastening nut 5 and a loosening prevention component 6; several bulletproof plates 1 are arranged in parallel and are covered by the side edge 2, and are connected into a whole on the outer periphery; a connecting block 3 is connected between adjacent bulletproof plates 1, and the bulletproof plate 1, the side edge 2 and the connecting block 3 are fixed by several linkage bolts 4 and fastening nuts 5; the loosening prevention component 6 is arranged on the connecting block 3, and the bolt anti-rotation and nut loosening prevention are realized by inserting the limiting rod 66 into the limiting hole of the linkage bolt 4.

[0027] In this embodiment, several bulletproof plates 1 are arranged in parallel, and the side edge 2 covers the outer periphery of several bulletproof plates 1 and partially covers the two side surfaces of several bulletproof plates 1; several linkage grooves are evenly spaced on the side edge 2 located on one side surface of several bulletproof plates 1, and the vertical projection of each linkage groove at least partially covers two adjacent bulletproof plates 1; several connecting blocks 3 are correspondingly arranged in several linkage grooves one by one, and the side edge 2, the bulletproof plate 1 and the connecting block 3 are fixed by several linkage bolts 4, each linkage bolt 4 is threadedly connected with a fastening nut 5, and each linkage bolt 4 is provided with a limiting hole along the radial direction.

[0028] In an optional implementation manner, to improve the bulletproof function of the bulletproof plate 1, each bulletproof plate 1 includes a bulletproof function layer, a heat insulation function layer, a sound insulation function layer and a structural function layer arranged in sequence. At the same time, by tightening each function layer through the side edge 2, the independence of the function layers is also realized, which is convenient for removal and replacement during maintenance. In addition, several through holes are provided on each function layer to facilitate the linkage bolt 4 to achieve fixation.

[0029] Exemplarily, the material of the bulletproof function layer can be composite structure ceramic; the material of the heat insulation function layer is a material with heat insulation performance to play a role in blocking heat transfer, such as glass wool, rock wool, foam plastic or aerogel; the material of the sound insulation function layer is a material with sound absorption performance, such as foam, fiberboard or porous material, which is used to absorb sound energy; the structural function layer is used to provide structural support.

[0030] In an optional implementation manner, as Figures 1 to 3 shown, several connecting holes 31 are spaced on each connecting block 3, the linkage bolt 4 sequentially passes through the connecting holes 31 of the side edge 2, the bulletproof plate 1 and the connecting block 3, and after the linkage bolt 4 passes through the connecting hole 31, it is threadedly connected with the fastening nut 5, and the fastening nut 5 contacts the connecting block 3 and the limiting rod 66 respectively, so as to realize the reinforcement and limitation of the fastening nut 5 through the limiting rod 66.

[0031] In this embodiment, as Figures 1 to 3As shown, a loosening prevention component 6 is provided on each connecting block 3. Each loosening prevention component 6 includes: a hollow block 61, a worm 62, a worm gear 63, a bidirectional lead screw 64, and a limiting rod 66; the hollow block 61 is fixedly connected to the connecting block 3, a cavity is provided inside the hollow block 61, the worm 62, the worm gear 63, and the bidirectional lead screw 64 are all arranged in the cavity, and the limiting rod 66 is slidably connected to the hollow block 61; wherein, the worm 62 is meshed with the worm gear 63, the worm gear 63 is connected to the bidirectional lead screw 64, and the limiting rod 66 is driven by the bidirectional lead screw 64 so that the limiting rod 66 cooperates with the limiting hole of the linkage bolt 4.

[0032] In an alternative embodiment, each loosening prevention component 6 further includes: a pressing block 65, the pressing block 65 is arranged in the cavity of the hollow block 61 and is slidably connected to the hollow block 61; two bidirectional lead screws 64 are symmetrically arranged at both ends of the worm gear 63, the bidirectional lead screw 64, the pressing block 65, and the limiting rod 66 are arranged in one-to-one correspondence and are connected in sequence; wherein, the bidirectional lead screw 64 is threadedly connected to the pressing block 65.

[0033] Exemplarily, the two bidirectional lead screws 64 in each loosening prevention component 6 are arranged in opposite directions, and the limiting rod 66 and the bidirectional lead screw 64 connecting the same pressing block 65 are arranged in a staggered manner to avoid interference between the limiting rod 66 and the bidirectional lead screw 64, thereby realizing the limiting and loosening prevention of two fastening nuts 5 through one loosening prevention component 6. In other words, on the pressing block 65 on one side, the limiting rod 66 and the bidirectional lead screw 64 are respectively connected to both sides of the pressing block 65, and the central axes of the limiting rod 66 and the bidirectional lead screw 64 are parallel but not coincident.

[0034] In an alternative embodiment, the end of each worm 62 extends out of the hollow block 61 and is connected to a rotating ring 7. Exemplarily, the outer side of the rotating ring 7 can be square or hexagonal to facilitate turning the worm 62 with a wrench.

[0035] The principle is as follows: The worm 62 is rotated through the rotating ring 7, driving the meshed worm gear 63 to rotate. Bidirectional lead screws 64 are provided at both ends of the worm gear 63, and the two bidirectional lead screws 64 both rotate with the worm gear 63 and in opposite rotation directions; each bidirectional lead screw 64 drives a pressing block 65 to slide in the cavity of the hollow block 61, and at the same time, the pressing block 65 slides along the axis direction of the bidirectional lead screw 64 under the limitation of the cavity of the hollow block 61; the two pressing blocks 65 move in opposite directions, and under the push of the pressing block 65, the limiting rod 66 extends out of the cavity of the hollow block 61 and cooperates with the limiting hole of the linkage bolt 4. Similarly, when the worm 62 is rotated in the reverse direction, under the transmission and limitation of the worm gear 63, the bidirectional lead screw 64, and the pressing block 65, the limiting rod 66 partially retracts into the cavity of the hollow block 61 and disengages from the limiting hole of the linkage bolt 4.

[0036] It should be noted that, due to the self-locking property of the cooperation between the worm 62 and the worm wheel 63, it can resist the position change caused by impact, prevent the limiting rod 66 from disengaging from the limiting hole of the linkage bolt 4, and improve the stability.

[0037] Furthermore, to avoid accidental contact with the rotating ring 7, a protective frame 8 is provided around the outer periphery of the rotating ring 7. The protective frame 8 is fixedly connected to the hollow block 61, and a closing plate 9 is provided thereon away from the hollow block 61. The rotating ring 7 is enclosed by the protective frame 8 and the closing plate 9. At the same time, for the convenience of operating the rotation of the worm 62, the closing plate 9 is also provided to be detachably connected to the protective frame 8. Exemplarily, after rotating the worm 62 to make the limiting rod 66 pass through the limiting hole of the linkage bolt 4, the closing plate 9 is connected to the protective frame 8 through sealant. When it is necessary to replace the bulletproof plate 1, only the sealant needs to be removed to achieve separation.

[0038] In an alternative embodiment, as Figure 4 shown, a plurality of hidden openings 10 are evenly spaced on the edge 2 on the other surface of several bulletproof plates 1. The plurality of hidden openings 10 are arranged in one-to-one correspondence with the plurality of linkage bolts 4, and each hidden opening 10 cooperates with the head of the linkage bolt 4.

[0039] Exemplarily, the hidden opening 10 is recessed in the surface of the edge 2, and the positioning and hiding of the head of the linkage bolt 4 are achieved through the hidden opening 10.

[0040] The working process of the composite structure ceramic insert of this embodiment is as follows: The linkage bolts 4 are sequentially passed through the edge 2 and the bulletproof plate 1, and the connecting block 3 is placed in the linkage groove, so that the connecting hole 31 of the connecting block 3 is sleeved on the linkage bolt 4. The connecting block 3 is tightened by the fastening nut 5, and several bulletproof plates 1 are spliced in sequence. After splicing is completed, the worm 62, the worm wheel 63 and the bidirectional lead screw 64 are rotated by driving the rotating ring 7, and the pressing block 65 slides in the cavity of the hollow block 61, so as to drive the limiting rod 66 to insert into the limiting hole, and the limiting rod 66 abuts against the fastening nut 5, thereby realizing the reinforcement and limitation of the fastening nut 5. When impacted, the fastening nut 5 is limited by the limiting rod 66, and the worm 62 and the worm wheel 63 are locked with each other, so as to be able to resist the loosening caused by the impact and enhance the stability of the entire protection system.

[0041] When some of the bulletproof plates 1 or the functional layers of some of the bulletproof plates 1 are damaged, the worm 62 is rotated to disengage the limiting rod 66 from the limiting hole, and then the fastening nut 5, the connecting block 3 and the linkage bolt 4 are sequentially removed, thereby realizing the separate replacement of the bulletproof plate 1 and the functional layer.

[0042] The composite structure ceramic insert plate provided by the embodiment of the present utility model locks and fixes the bulletproof plate and the edge by a linkage bolt, and realizes the assembly and splicing between two adjacent bulletproof plates through a connecting block. When some of the bulletproof plates are damaged, the damaged bulletproof plate can be replaced separately, thereby reducing the maintenance cost and simplifying the maintenance process. The limiting rod of the anti-loosening component is inserted into the limiting hole of the linkage bolt. When impacted, the worm locks the worm gear, and then the limiting rod abuts and limits the fastening nut, so as to resist the loosening caused by the impact and enhance the stability of the whole protection system.

[0043] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or sequence between these entities or operations. Moreover, the term "comprising", "including" or any other variant is intended to cover non-exclusive inclusion, so that an article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed.

For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
