Description

Technical Field

[0001] The utility model belongs to the technical field of safety and explosion-proof, and specifically relates to a barrier and explosion-proof ball. Background Art

[0002] The explosive ball is an important protective device during the relocation of explosives. It can limit the explosion range of the explosives inside the tank, preventing and reducing the damage to surrounding people and objects when the explosives explode. It can effectively suppress the lethality of the explosion. Therefore, the device is suitable for on-site use such as public security, airports, railway stations, customs, important places and large-scale events security inspections and bomb disposal.

[0003] The existing explosion-proof ball has a simple structure, which is mostly designed to facilitate the use of staff. However, it still has obvious defects in actual use. The opening and closing of the explosion-proof ball is generally achieved by shaking the threaded rod to drive the sealing cover to rise and fall. Each shaking of the threaded rod requires several rotations, which is not only slow but also physically demanding. Although an electric telescopic rod has been used to replace the lifting, the overall opening and closing speed is still slow, resulting in the explosion-proof ball being unable to close quickly in an emergency, thereby reducing the explosion-proof function and safety. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a barrier and explosion-proof ball.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A barrier explosion-proof ball, comprising a base, an explosion-proof sphere, an explosion-proof ball cover, and an adsorption seat. The explosion-proof sphere is provided above the base and fixed between the explosion-proof sphere and the base via supporting legs. The four corners of the upper end of the base are fixed to the top plate via guide columns. An electric push rod is fixed to the bottom of the top plate, and an adsorption seat is fixed to the telescopic end of the electric push rod. An electromagnet is provided inside the adsorption seat for adsorbing the explosion-proof ball cover. The explosion-proof ball cover is located above the explosion-proof sphere.

[0007] The four corners of the explosion-proof sphere are fixed with guide blocks for sleeved guide posts. A contact plate is fixed to the outside of each guide post. A return spring contacts the contact plate and the guide block. A ball is provided inside the guide block to contact the surface of the guide post.

[0008] The contact surface between the explosion-proof ball cover and the explosion-proof sphere is provided with an anti-dropping piece, and the upper end of the explosion-proof sphere is provided with a plug hole for plugging the anti-dropping piece. One side of each plug hole is connected to an open groove for hinged connection of the limit piece.

[0009] Optionally, a polyurethane protective pad is bonded to the bottom surface of the adsorption seat.

[0010] Optionally, a support block is fixed to the middle of the upper end of the base, and rotating rollers for contacting the bottom of the explosion-proof sphere are rotatably connected to both ends of the support block.

[0011] Optionally, support bars are fixed on both sides of the base, a chassis is symmetrically fixed on the upper end of each support bar, and a damping rod is fixed inside each chassis, the telescopic end of each damping rod passes through the interior of the support bar and is fixed to the support plate, a self-locking universal wheel is installed at the bottom of each support plate, and a buffer spring is provided between the support plate and the support bar, and the buffer spring is sleeved on the outside of the telescopic end of the damping rod.

[0012] Optionally, a trigger support is provided inside the plug-in hole, a rubber protective pad is fixed inside the trigger support, and a J-shaped piece is fixed to the bottom of the trigger support, the J-shaped piece is installed inside the give-way cavity, the two ends of the give-way cavity are respectively connected to the plug-in hole and the open groove, and a give-way ring is fixed inside one end of the give-way cavity, the upper end of the give-way ring is in contact with a spring body, the spring body is sleeved on the outside of the J-shaped piece, and the upper end of the spring body is in contact with the limit ring outside the J-shaped piece, and the other end of the J-shaped piece is used to contact the limit piece.

[0013] Optionally, the limit member is hinged inside the open slot, a guide rod is fixed at the front end of the limit member, and the guide rod is installed in the arc groove on the front side of the open slot, a positioning plate is fixed on the outside of the open side, a limit spring for resisting the limit member is fixed on the side of the positioning plate, and a toggle block is fixed on the outside of the limit member side.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] 1. The explosion-proof ball cover of the utility model uses the electromagnet inside the adsorption seat to adsorb explosive objects. When the explosive object is placed inside the explosion-proof ball, the electromagnet is powered off and loses its magnetic force. The explosion-proof ball cover quickly falls down and closes with the explosion-proof ball, thus completing a quick closure.

[0016] 2. The utility model triggers the limit piece by providing a trigger support, that is, after the explosion-proof ball cover and the explosion-proof sphere are closed, the anti-slip part is pressed into the inside of the plug-in hole. At this time, the trigger support is pressed down, causing the other end of the J-shaped part to drop, so that one side of the limit piece loses its limit. At this time, the limit piece is pressed into the groove body opened in the middle of the anti-slip part, thereby limiting the anti-slip part inserted into the plug-in hole to ensure the sealing between the explosion-proof ball cover and the explosion-proof sphere.

[0017] The specific implementation of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] See also Figures 1 to 6 The utility model provides a technical solution: a barrier explosion-proof ball, comprising a base 1, an explosion-proof sphere 2, an explosion-proof ball cover 9 and an adsorption seat 7. The explosion-proof sphere 2 is provided above the base 1, and is fixed between the explosion-proof sphere 2 and the base 1 by supporting legs 3. The four corners of the upper end of the base 1 are fixed to the top plate 5 by guide columns 4. An electric push rod 6 is fixed to the bottom of the top plate 5, and an adsorption seat 7 is fixed to the telescopic end of the electric push rod 6. An electromagnet 8 is provided inside the adsorption seat 7. The electromagnet 8 is used to adsorb the explosion-proof ball cover 9. The explosion-proof ball cover 9 is located above the explosion-proof sphere 2.

[0032] The four corners of the explosion-proof sphere 2 are fixed with guide blocks 10 for sleeved guide posts 4. A contact plate 11 is fixed to the outside of each guide post 4. A return spring 12 is provided between the contact plate 11 and the guide block 10. A ball 13 is provided inside the guide block 10 to contact the surface of the guide post 4.

[0033] The contact surface of the explosion-proof ball cover 9 and the explosion-proof sphere 2 is provided with an anti-slip part 14, and an insertion hole 15 for the anti-slip part 14 to be inserted is opened at the upper end of the explosion-proof sphere 2. One side of each insertion hole 15 is connected to an open groove 33 for the limit member 16 to be hinged. Considering that the existing explosion-proof ball has a simple structure, most of them are for the convenience of use by staff, but in actual use, it still has obvious defects, that is, the opening and closing of the explosion-proof ball is generally achieved by shaking the threaded rod to drive the sealing cover to lift and lower, and each shaking of the threaded rod requires several turns of rotation, which is not only slow but also physically demanding. Although an electric telescopic rod is used to replace the lifting in the future, the overall opening and closing speed is still slow, resulting in the explosion-proof ball being unable to close quickly in an emergency, thereby reducing the explosion-proof function and safety. The utility model uses the electromagnet 8 inside the adsorption seat 7 to adsorb through the explosion-proof ball cover 9 so that when an explosive object is placed inside the explosion-proof sphere 2, the electromagnet 8 can be powered off and loses its magnetic force, and the explosion-proof ball cover 9 quickly falls and closes with the explosion-proof sphere 2 to complete the quick closure.

[0034] A polyurethane protective pad 17 is bonded to the bottom surface of the adsorption seat 7 , and the polyurethane protective pad 17 protects the contact surface between the adsorption seat 7 and the explosion-proof ball cover 9 .

[0035] Among them, a support block 18 is fixed to the middle part of the upper end of the base 1, and rotating rollers 19 for resisting the bottom of the explosion-proof sphere 2 are rotatably connected to both ends of the support block 18. By setting the support block 18 and the rotating rollers 19, the middle part of the bottom end of the explosion-proof sphere 2 is resisted.

[0036] Among them, support bars 20 are fixed on both sides of the base 1, and a chassis 21 is symmetrically fixed to the upper end of each support bar 20, and a damping rod 22 is fixed inside each chassis 21, and the telescopic end of each damping rod 22 passes through the interior of the support bar 20 and is fixed to the support plate 23. A self-locking universal wheel 24 is installed at the bottom of each support plate 23, and a buffer spring 25 is in contact between the support plate 23 and the support bar 20. The buffer spring 25 is sleeved on the outside of the telescopic end of the damping rod 22. By arranging the damping rod 22 and cooperating with the buffer spring 25, a buffering effect is played on the self-locking universal wheel 24, that is, when the self-locking universal wheel 24 encounters bumps during movement, the elastic force will be absorbed by the buffer spring 25, and then in the process of releasing the elastic potential energy of the buffer spring 25, the damping rod 22 will be used to curb the release of the elastic potential energy to complete the buffering process.

[0037] Among them, the interior of the plug hole 15 is provided with a trigger holder 26, a rubber protective pad 27 is fixed inside the trigger holder 26, and a J-shaped member 28 is fixed to the bottom of the trigger holder 26, and the J-shaped member 28 is installed inside the clearance cavity 29. The two ends of the clearance cavity 29 are respectively connected to the plug hole 15 and the open groove 33, and a clearance ring 30 is fixed inside one end of the clearance cavity 29. The upper end of the clearance ring 30 abuts against the spring body 31, the spring body 31 is sleeved on the outside of the J-shaped member 28, and the upper end of the spring body 31 abuts against the limit ring 32 on the outside of the J-shaped member 28. The other end of the J-shaped part 28 is used to abut the limit part 16. The trigger support 26 is provided to trigger the limit part 16, that is, after the explosion-proof ball cover 9 and the explosion-proof sphere 2 are closed, the anti-slip part 14 abuts against the inside of the plug-in hole 15. At this time, the trigger support 26 is pressed down, causing the other end of the J-shaped part 28 to drop, so that one side of the limit part 16 loses its limit. At this time, the limit part 16 abuts against the groove body opened in the middle of the anti-slip part 14, thereby limiting the anti-slip part 14 inserted into the plug-in hole 15 to ensure the sealing between the explosion-proof ball cover 9 and the explosion-proof sphere 2.

[0038] Among them, the limit member 16 is hinged inside the open groove 33, and a guide rod 34 is fixed at the front end of the limit member 16, and the guide rod 34 is installed in the arc groove 35 on the front side of the open groove 33, and a positioning plate 36 is fixed on the outside of the open side, and a limiting spring 37 for resisting the limit member 16 is fixed on the side of the positioning plate 36, and a toggle block 38 is fixed on the outside of the side of the limit member 16. By setting the limiting spring 37, the limit member 16 is driven, that is, after the J-shaped member 28 descends, the side of the limit member 16 loses its limit, and at this time the limiting spring 37 resets and ejects, so that the side of the limit member 16 is inserted into the groove body on the side of the anti-slip member 14, thereby limiting the anti-slip member 14.
