A quick connection structure for a convenient mine-proof plate and an armored vehicle chassis

Abstract

The present invention discloses a rapid connection structure for a convenient mine-proof plate and an armored vehicle chassis, including an armored vehicle, a mine-proof plate, and two rapid connection structures. By driving two rotating shafts to rotate clockwise through a handle, two arc connecting rods will push and extrude two movable clamping columns outwards, so that the two movable clamping columns slide towards the direction of the fixed movable clamping column on the outer walls of the two limiting round rods. When the two movable clamping columns come into contact with the two grooved cylinders, the two movable clamping columns and the two fixed movable clamping columns will quickly clamp the grooved cylinders. At the same time, the handle will also drive the ratchet to rotate clockwise. At this time, through the expansion and contraction of the second spring, the inclined surface plug column will be inserted into multiple grooves on the ratchet, and through the vertical surface of the inclined surface plug column, the reverse rotation of the ratchet can be avoided, completing the locking work, so that the mine-proof plate can be quickly installed on the armored vehicle, saving operation time.

Description

Technical Field

[0001] The invention belongs to the technical field related to armored vehicle components, and particularly relates to a rapid connection structure for conveniently connecting an anti-mine plate and an armored vehicle chassis. Background Technique

[0002] An armored vehicle is a variety of tracked or wheeled military vehicles with armor protection, and is a general term for military or police vehicles equipped with armor. A tank is also a type of tracked armored vehicle of an armored vehicle, but it is usually independently classified according to its combat use in practice. Most armored vehicles refer to vehicle types with weaker protection and firepower than tanks. When an armored vehicle is used for combat purposes and passes through an area where landmines are buried, it is likely to detonate landmines. Although the chassis has a certain protective effect, when a landmine explodes and generates a shock wave, the chassis of the armored vehicle will receive a large instantaneous upward dynamic load, and then undergo large deformation, causing the internal structure of the vehicle and its members to bear a great deal. Therefore, in order to protect the internal structure of the vehicle and the safety of its members, an anti-mine plate for protection is installed on the chassis of the armored vehicle, which can effectively protect the internal structure of the vehicle and the safety of its members.

[0003] When installing the existing anti-mine plate, installers need to use tools to pass multiple bolts through the round holes of the anti-mine plate and thread them into the threaded holes of the armored vehicle chassis in order to install the anti-mine plate on the chassis of the armored vehicle. Due to the large number of bolts installed, the operation time will be delayed, the installation efficiency will be reduced, and the ability to respond to emergencies will be weak. Summary of the Invention

[0004] The purpose of the present invention is to provide a rapid connection structure for conveniently connecting an anti-mine plate and an armored vehicle chassis, so as to solve the problems mentioned in the above background technique that installing the anti-mine plate by bolts will delay the operation time, reduce the installation efficiency, and have a weak ability to respond to emergencies.

By moving the two arc connecting rods, the two movable clamping columns slide reciprocally on the outer walls of the two limiting round rods, facilitating the two movable clamping columns and the two fixed movable clamping columns to clamp two grooved cylinders. The middle outer walls of the two limiting round rods are sleeved with first springs, and the two ends of the two first springs are fixedly connected to the two movable clamping columns.

[0007] Preferably, the two locking mechanisms of the present invention include a first protective shell, a ratchet wheel, an inclined surface plug column, a second spring, and a T-shaped cylinder.

When the two movable clamping columns contact the two card slot type cylinders, the two movable clamping columns and the two fixed moving clamping columns will quickly clamp the card slot type cylinder.

[0016] 2. When the handle of the present invention drives the ratchet to rotate clockwise, the inner wall of the groove of the ratchet will contact the inclined surface of the inclined surface plug and push the inclined surface plug and the T-shaped cylinder to move outwards to complete the separation work, and the second spring will also be compressed. At this time, through the expansion and contraction of the second spring, the inclined surface plug will fit with the rotating edge of the ratchet, and the inclined surface plug can also extend into multiple grooves on the ratchet.

The mine protection plate 2 is sleeved on the outer wall of the four card slot type cylinders 6, and the four card slot type cylinders 6 penetrate through and extend out of the two clamping and fixing mechanisms. The two clamping and fixing mechanisms include four movable clamping columns 11 and four fixed movable clamping columns 15, and the four card slot type cylinders 6 are clamped and fixed by the four movable clamping columns 11 and the four fixed movable clamping columns 15, so that the mine protection plate 2 is fixed on the outer wall of the four card slot type cylinders 6, and the two locking mechanisms complete the locking work on the two clamping and fixing mechanisms, so that the mine protection plate 2 is quickly installed on the chassis of the armored vehicle 1. The mine protection plate 2 is used to protect the chassis of the armored vehicle 1.

[0034] Such as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown in the figure, the clamping and fixing mechanism of the present invention includes a second protective shell 4, two movable clamping columns 11, a rotating shaft 12, two limiting round rods 7, two first springs 8, two arc connecting rods 9 and two fixed movable clamping columns 15. A circular sleeve column 17 is welded at the middle of the top of the second protective shell 4. A rotating shaft 12 is rotatably connected inside the circular sleeve column 17. An annular support column 18 is fixedly connected to the outer wall on the upper side of the rotating shaft 12. Second connecting ears 16 are fixedly connected to the outer walls on the left and right sides of the annular support column 18. The lower end of the rotating shaft 12 penetrates through the bottom of the second protective shell 4, and the rotating shaft 12 is rotatably connected to the second protective shell 4. Two fixed movable clamping columns 15 are welded on the front and rear inner walls of the second protective shell 4, and the two fixed movable clamping columns 15 are located on the front and rear sides of the rotating shaft 12. Three equally spaced tapered elastic clamping rings 10 are welded on the inner walls of the middle parts of the two fixed movable clamping columns 15. Two symmetric limiting round rods 7 are fixedly connected between the two fixed movable clamping columns 15, and the two limiting round rods 7 are located on the left and right sides of the rotating shaft 12. Two symmetric movable clamping columns 11 are slidably connected to the outer walls on both sides of the two limiting round rods 7, and the two movable clamping columns 11 are opposite to the two fixed movable clamping columns 15. Three equally spaced tapered elastic clamping rings 10 are welded on the inner walls of the middle parts of the two movable clamping columns 11 close to the two fixed movable clamping columns 15. First connecting ears 14 are welded on the outer walls of the two movable clamping columns 11 close to the rotating shaft 12. Arc connecting rods 9 are rotatably sleeved between the two first connecting ears 14 and the two second connecting ears 16. By the movement of the two arc connecting rods 9, the two movable clamping columns 11 reciprocally slide on the outer walls of the two limiting round rods 7, facilitating the clamping of the two movable clamping columns 11 and the two fixed movable clamping columns 15 on the two grooved cylinders 6. The middle outer walls of the two limiting round rods 7 are sleeved with first springs 8, and the two ends of the two first springs 8 are fixedly connected to the two movable clamping columns 11. By the contraction of the two first springs 8, the two movable clamping columns 11, the two arc connecting rods 9, and the two second connecting ears 16 are restored to the initial state. A handle 5 is fixedly connected to the lower end of the rotating shaft 12. Second through holes are opened on the left and right sides of the upper and lower ends of the second protective shell 4, and the inner diameter of the second through holes is larger than the outer diameter of the grooved cylinder 6. A third through hole matching the rotating shaft 12 is opened in the middle of the lower end of the second protective shell 4, and the third through hole is communicated with the first through hole of the first protective shell 3. Through the clamping and fixing mechanism, the clamping and fixing work with the grooved cylinder 6 can be quickly completed, thus enabling the rapid installation of the anti-mine plate 2.

[0035] As Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown in the figure, the two locking mechanisms of the present invention include a first protective housing 3, a ratchet wheel 13, an inclined surface insertion post 19, a second spring 20, and a T-shaped cylinder 21. The first protective housing 3 is welded to the middle of the lower surface of the second protective housing 4, and the rotating shaft 12 penetrates and extends to the lower surface of the first protective housing 3. The rotating shaft 12 is rotatably connected to the first protective housing 3. The ratchet wheel 13 is sleeved on the outer wall of the lower side of the rotating shaft 12, and the ratchet wheel 13 is located at the center inside the first protective housing 3. One side of the first protective housing 3 is rotatably connected with a T-shaped cylinder 21 extending into its interior. One end of the T-shaped cylinder 21 close to the ratchet wheel 13 is fixedly connected with an inclined surface insertion post 19, and the inclined surface insertion post 19 extends into the groove inside the ratchet wheel 13 to complete the locking work. A second spring 20 is sleeved on the outer wall of the T-shaped cylinder 21 close to the inclined surface insertion post 19, and the two ends of the second spring 20 are respectively in contact with one end of the inclined surface insertion post 19 and the inner wall of one side of the first protective housing 3. Through holes matching the rotating shaft 12 are opened in the middle of the upper and lower ends of the first protective housing 3, and a circular hole matching the T-shaped cylinder 21 is opened in the middle of one side of the first protective housing 3. Through the two locking mechanisms, the locking work can be quickly completed, so that the clamping and fixing mechanism can quickly clamp and fix the grooved cylinder 6, thereby enabling the mine protection plate 2 to be quickly installed on the chassis of the armored vehicle 1.

[0036] As Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown in the figure, four through holes matching the grooved cylinder 6 are opened on the left and right sides of the mine protection plate 2 of the present invention, and the through holes are communicated with the second through holes of the second protective housing 4. The outer wall of the mine protection plate 2 is coated with an insulating and oxidation-resistant paint layer structure. Through the mine protection plate 2, the chassis of the armored vehicle 1 can be protected.

[0037] As Figure 8 As shown in the figure, three conical ring grooves matching the conical elastic engaging ring 10 are opened on the lower side of the grooved cylinder 6 of the present invention. The lower surface of the grooved cylinder 6 is flush with the lower surface of the second protective housing 4. By engaging the conical ring groove of the grooved cylinder 6 with the conical elastic engaging ring 10, the phenomenon of falling off can be avoided.

[0038] As Figure 8 , Figure 10 , Figure 12 and Figure 13 As shown in the figure, a triangular opening groove is opened in the middle of one end of the fixed movable clamping column 15 facing the rotating shaft 12, and three conical elastic engaging rings 10 are welded to the inner wall of the triangular opening groove at equal intervals. Through the fixed movable clamping column 15, the clamping work can be carried out better.

[0039] As Figure 8 ,Figure 9 , Figure 10 , Figure 12 and Figure 13 As shown in Figure 12 , Figure 13 , a triangular opening groove is formed in the middle of one end of the movable clamping column 11 of the present invention facing the fixed movable clamping column 15. Through holes matching the limiting round rods 7 are formed on the left and right sides of the movable clamping column 11. The length, width and height of the movable clamping column 11 are the same as those of the fixed movable clamping column 15. The clamping work can be better carried out through the movable clamping column 11.

[0040] Working principle and usage process of the present invention: When in use, the staff first aligns the four fourth through holes of the anti-mine plate 2 and the four third through holes on the two clamping and fixing mechanisms with the four slot-type cylinders 6, and respectively penetrates the four slot-type cylinders 6 through the four fourth through holes of the anti-mine plate 2 and the four third through holes on the two clamping and fixing mechanisms, so that the four slot-type cylinders 6 are flush with the lower surfaces of the two second protective shells 4, so that the inner walls of the triangular opening grooves of the four fixed movable clamping columns 15 are in contact with the inner walls of the four slot-type cylinders 6, and the three conical elastic engagement rings 10 on the four fixed movable clamping columns 15 are engaged with the three conical ring grooves on the four slot-type cylinders 6. Then, when the staff rotates the handle 5 on a quick connection structure clockwise, the rotating shaft 12 will be driven to rotate clockwise, thereby driving the two second connecting ears 16 to rotate clockwise, so that the two arc connecting rods 9 push the two movable clamping columns 11 outwards. When the two arc connecting rods 9 push the two movable clamping columns 11 outwards, the two movable clamping columns 11 will slide towards the two fixed movable clamping columns 15 on the outer walls of the two limiting round rods 7 and stretch the two first springs 8. When the inner walls of the triangular opening grooves of the two movable clamping columns 11 are in contact with the corresponding two slot-type cylinders 6, and the conical elastic engagement rings 10 on the two movable clamping columns 11 are engaged with the three conical ring grooves on the corresponding two slot-type cylinders 6, the two movable clamping columns 11 and the two fixed movable clamping columns 15 will clamp the slot-type cylinders 6;

[0041] During the rotation of the handle 5, the ratchet wheel 13 will also be driven to rotate clockwise simultaneously. During the rotation of the ratchet wheel 13, one inner wall of the groove on the ratchet wheel 13 will contact the inclined surface of the inclined surface plug 19 and push the inclined surface plug 19 and the T-shaped cylinder 21 to move outward. When the inclined surface plug 19 moves outward, it will squeeze the second spring 20. When the inclined surface plug 19 moves to the edge of the ratchet wheel 13, due to the reaction force of the second spring 20, the inclined surface plug 19 will fit with the ratchet wheel 13. When moving to the next groove, the second spring 20 will elongate, causing the inclined surface plug 19 to extend into the next groove, and through the vertical surface of the inclined surface plug 19, the reverse rotation of the ratchet wheel 13 is avoided. After that, the inclined surface plug 19 will contact multiple grooves according to the above steps. When the two movable clamping columns 11 and the two fixed movable clamping columns 15 clamp the two grooved cylinders 6, the inclined surface plug 19 will extend into the corresponding groove of the ratchet wheel 13 to complete the locking operation, so that a quick connection structure is fixedly connected to the two grooved cylinders 6;

[0042] Subsequently, the staff can operate another quick connection structure according to the above steps, so that another quick connection structure is fixedly connected to the other two grooved cylinders 6, thereby enabling the mine protection plate 2 to be quickly installed on the chassis of the armored vehicle 1.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
