[0005] As a preferred scheme of the present application, the axes of the fixed column one and the guide column are perpendicular to the front face of the damping box, the axis of the fixed column two is parallel to the front face of the damping box, the spring one is movably sleeved on the outer surface of the lifting column, and the two ends of the spring one are elastically connected with the lifting column and the lifting cylinder respectively.

[0006] As a preferred scheme of the present application, the magnetic attraction is generated between the counterweight one and the counterweight two, the counterweight two is movably sleeved on the top of the outer surface of the support column, the counterweight one rotates around the axis of the fixed column one, and the counterweight two rotates around the axis of the fixed column two.

[0007] As a preferred scheme of the present application, the abutting piece comprises a support cylinder fixedly installed on the top of the base plate, the spring two and the telescopic column are movably sleeved in the inside of the support cylinder, the top end of the telescopic column is fixedly connected with the bottom frame, and the telescopic column is elastically supported in the support cylinder through the spring two.

[0008] As a preferred scheme of the present application, the clamping grooves are arranged in multiple groups and horizontally equidistantly distributed on the bottom of the damping plate, and the number of the clamping grooves is greater than that of the abutting columns.

[0009] As a preferred scheme of the present application, the abutting column is circular in cross section and is adapted to be clamped in the clamping groove, and the center of the abutting column is lower than the bottom of the damping plate.

[0010] As a preferred scheme of the present application, the spring three is arranged in two groups and symmetrically distributed on the left and right sides of the rack, and the two ends of the spring three are elastically connected with the rack and the inner wall of the damping box respectively.

[0011] As a preferred scheme of the present application, the guide column penetrates through the two sides of the rack and is located between the hinge block and the upper part of the rack.

[0012] The present application has the following beneficial effects:

[0013] 1. The device divides the damping modules into two parts according to the horizontal and vertical distribution, avoids the rotation phenomenon caused by the traditional rope hoisting counterweight, takes the damping box as the main body, and sets the horizontal damping module (fixed column one-counterweight one) and the vertical damping module (fixed column two-abutting column) which are independently distributed up and down in the damping box through the fixed column one and the fixed column two respectively. The two modules take the axes of the fixed column one and the fixed column two as the rotation center lines, can rotate around the fixed column one and the fixed column two when the device is subjected to vibration, and can offset the vibration from the horizontal and vertical directions respectively. Due to the limiting of the fixed column one and the fixed column two, the counterweight one and the counterweight two for counterweight can be reset to the original position after completing displacement damping each time, and the next damping operation can be performed, which greatly enhances the damping effect.

[0014] 2. At the same time, the transverse shock absorption module (fixed column one to counterweight one) designed in this device, when the counterweight one drives the lifting column and the lifting cylinder to rotate around the axis of the fixed column one, utilizes the inertia of the counterweight one and the lifting column to move downward and extend along the axis of the lifting cylinder, so that the spring one is further compressed, generating an additional rebound force. When the lifting cylinder moves to an angle with its initial axis, the resultant force acting on the counterweight one drives the counterweight one to rotate and makes the counterweight one return to its original position more quickly.

[0015] 3. This device uses gears and racks to convert the rotation of the support column and counterweight into the reciprocating displacement of the rack along the axis of the guide column through rotational damping. The rack drives the damping plate to move, so that the abutment column and the slot can be matched and engaged, generating lateral resistance that hinders the movement of the rack and the damping plate, thus consuming the energy generated by vibration. Since the displacement thrust is not offset by friction between the abutment column and the damping plate, the service life of the device can be extended. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 9 As shown, this embodiment of the invention provides a seismic-resistant connector for a school building, including a base 1 and a base plate 2. A damping box 3 is installed on the top of the base plate 2, and a support plate 4 is fixedly installed on the top of the damping box 3. From top to bottom, a first fixed column 5, a second fixed column 10, and a guide column 16 are sequentially fixed to the inner wall of the damping box 3. A lifting cylinder 6 is rotatably installed on the outer surface of the first fixed column 5. A spring 7 and a lifting column 8 are movably connected inside the lifting cylinder 6. A counterweight block 9 is fixedly connected to the bottom end of the lifting column 8. A hinge is rotatably installed on the outer surface of the second fixed column 10. The hinge block 13 has gears 12 fixedly connected to both sides via connecting cylinders 23. The top of the hinge block 13 is fixedly connected to a support column 14 and a counterweight block 15. The outer surface of the guide column 16 is movably fitted with a rack 17 and a spring 18. The rack 17 meshes with the gear 12. A damping plate 19 is fixedly installed at the bottom of the rack 17. A slot 22 is opened at the bottom of the damping plate 19. An abutment 11 is installed at the top of the base plate 2. A bottom frame 20 is installed at the top of the abutment 11. Multiple sets of abutment columns 21 are fixedly installed on the inner wall of the bottom frame 20.

[0028] The device divides the damping modules into two parts in the vertical direction of the horizontal and vertical direction, avoiding the rotation phenomenon caused by the traditional rope hoisting counterweight, and taking the damping box 3 as the main body, the upper and lower independent horizontal damping modules (fixed column one 5~counterweight block one 9) and the vertical damping modules (fixed column two 10~abutting column 21) are arranged in the damping box 3 through the fixed column one 5 and the fixed column two 10 respectively. The two groups of modules are respectively taken as the rotation center line of the fixed column one 5 and the fixed column two 10, and can rotate around the fixed column one 5 and the fixed column two 10 when the device is subjected to vibration, and can offset the vibration from the horizontal and vertical directions respectively. Due to the limiting of the fixed column one 5 and the fixed column two 10, the counterweight block one 9 and the counterweight block two 15 for counterweight can be reset to the original position after completing displacement damping each time, and the next damping operation is carried out, which greatly enhances the damping effect.

[0029] At the same time, the horizontal damping module (fixed column one 5~counterweight block one 9) designed by the device rotates around the axis of the fixed column one 5 when the counterweight block one 9 drives the hoisting column 8 and the hoisting cylinder 6 to move downward along the axis of the hoisting cylinder 6 and extend, so that the spring one 7 is further compressed, and additional elastic force is generated. When the hoisting cylinder 6 moves to an angle with its initial axis, the resultant force acting on the counterweight block one 9 drives the counterweight block one 9 to rotate and makes the counterweight block one 9 reset faster.

[0030] The device uses the gear 12 and the rack 17 to convert the rotation generated by the rotation damping into the reciprocating displacement of the rack 17 along the axis of the guide column 16, and drives the damping plate 19 to move through the rack 17, so that the abutting column 21 and the clamping groove 22 are matched and clamped, and the lateral resistance which hinders the movement of the rack 17 and the damping plate 19 is generated, and the energy generated by the vibration is consumed. Since the friction force is not used between the abutting column 21 and the damping plate 19 to offset the displacement thrust, the service life of the device can be prolonged.

[0031] Finally, the magnetic attraction between the counterweight block one 9 and the counterweight block two 15 is used to assist the device to maintain the stability of the counterweight block one 9 and the counterweight block two 15 in the normal state.

[0032] The axes of the fixed column one 5 and the guide column 16 are perpendicular to the front of the damping box 3, the axis of the fixed column two 10 is parallel to the front of the damping box 3, the spring one 7 is movably sleeved on the outer surface of the hoisting column 8, and the two ends of the spring one 7 are respectively elastically connected with the hoisting column 8 and the hoisting cylinder 6.

[0033] The fixed column one 5 and the fixed column two 10 are vertically distributed above and below each other, and the damping modules of the device are divided into horizontal and vertical directions, which reduces interference. The guide column 16 is responsible for guiding and supporting the rack 17, and cooperates with the spring three 18 to produce a buffering effect when the rack 17 moves, thereby improving stability.

[0034] The magnetic attraction is generated between the counterweight 9 and the counterweight 15, the counterweight 15 is fixedly sleeved on the top of the outer surface of the support column 14, the counterweight 9 rotates around the axis of the fixed column 5, and the counterweight 15 rotates around the axis of the fixed column 10;

[0035] The auxiliary device maintains the stability of the counterweight 9 and the counterweight 15 in the normal state by the magnetic attraction between the counterweight 9 and the counterweight 15, and assists the hoisting cylinder 6, the hoisting column 8, the counterweight 9 and the support column 14 and the counterweight 15 to be quickly reset.

[0036] The abutting piece 11 comprises a support cylinder 111 fixedly installed on the top of the base plate 2, the inside of the support cylinder 111 movably sleeves a spring 112 and a telescopic column 113, the top end of the telescopic column 113 is fixedly connected with the bottom frame 20, and the telescopic column 113 is elastically supported in the support cylinder 111 through the spring 112;

[0037] The abutting piece 11 is responsible for providing upward pressure for the bottom frame 20, when the rack 17 drives the damping plate 19 to move back and forth along the axis of the guide column 16, the clamping groove 22 formed in the bottom of the damping plate 19 abuts against the outer surface of the abutting column 21, after overcoming the lateral resistance generated by the two, the abutting column 21 is separated from the clamping groove 22 and moves downward under the limitation of the damping plate 19, drives the telescopic column 113 to compress the spring 112 downward, and generates upward elastic force.

[0038] The clamping groove 22 is provided in multiple groups and is horizontally equidistantly distributed on the bottom of the damping plate 19, and the number of the clamping groove 22 is greater than that of the abutting column 21;

[0039] The multiple groups of clamping grooves 22 are clamped and matched with the abutting columns 21, and abut downward under the pressure generated by the abutting piece 11, and generate several times of lateral resistance, thereby playing a role of longitudinal damping, in addition, since the abutting column 21 and the damping plate 19 do not adopt friction force to offset displacement thrust, the service life of the device can be prolonged.

[0040] The abutting column 21 is circular in cross section and is clamped and matched with the clamping groove 22, and the center of the abutting column 21 is lower than the bottom of the damping plate 19;

[0041] The cylindrical abutting column 21 can be clamped and matched with the clamping groove 22 under the displacement of the rack 17, and is separated from the clamping groove 22 after overcoming the lateral resistance.

[0042] Note: the lateral resistance, as shown in the formula, when the damping plate 19 moves horizontally relative to the abutting column 21 (only when the damping plate 19 moves horizontally relative to the abutting column 21, the lateral resistance is generated, and the formula is not applicable when the damping plate 19 moves vertically relative to the abutting column 21); Figure 6 Figure 6 ​When the angle of view, in fact, the moving direction of the damping plate 19 is the front and back movement along the front of the damping box 3, the abutting column 21 is clamped in the clamping groove 22, and the limiting resistance generated by the contact surface of the remaining clamping grooves 22 is the lateral resistance.

[0043] The spring three 18 is arranged in two groups and symmetrically distributed on the left and right sides of the rack 17, and the two ends of the spring three 18 are respectively elastically connected with the rack 17 and the inner wall of the damping box 3.

[0044] The spring three 18 is responsible for buffering the rack 17 by using the elastic force generated by compression and stretching when the rack 17 is displaced, and the lateral resistance generated by the disengagement and re-engagement of the abutting column 21 and the clamping groove 22 cooperates with the spring three 18 to realize longitudinal damping.

[0045] The guide column 16 penetrates through the two sides of the rack 17 and is located between the hinge block 13 and the upper part of the rack 17.

[0046] The guide column 16 is responsible for guiding and supporting the rack 17, and the outer surface of the guide column 16 is further sleeved with the spring three 18 to provide buffering and resetting functions for the movement of the rack 17.

[0047] Working principle:

[0048] When the device is used, the support plate 4 provides support for the building, and when the base 1 and the base plate 2 are vibrated:

[0049] Horizontal: The damping box 3 produces horizontal left and right displacement as a whole, at this time, the counterweight block one 9 drives the hanging column 8 and the hoisting cylinder 6 to rotate around the axis of the fixed column one 5 on the side opposite to the displacement direction of the device, at this time, the hanging column 8 and the counterweight block one 9 are displaced downward along the axis of the hoisting cylinder 6 under the action of inertia, and the spring one 7 is compressed, so that the hanging column 8 obtains additional rebounding tension, and cooperates with the tension of the hanging column 8 and the gravity of the counterweight block one 9 to generate a horizontal reaction force on the counterweight block one 9, which is the same as the displacement generated by the vibration of the device. Since the additional compression rebounding force generated by the spring one 7 increases the tension of the hanging column 8 on the counterweight block one 9, the horizontal tension of the counterweight block one 9 is increased, and the counterweight block one 9 is quickly pulled back, thereby achieving damping and speeding up the resetting speed of the counterweight block one 9.

[0050] Longitudinal (such as Figure 5When the device is shaken from the longitudinal direction, the device is displaced along the axis of the guide column 16, at this time, the hinge block 13, the support column 14 and the counterweight block two 15 rotate around the axis of the fixed column two 10 to the opposite side of the displacement of the device, under the action of inertia, to offset the shock, at this time, the hinge block 13 drives the gear 12 to rotate through the connecting barrel 23, the gear 12 drives the rack 17 to start moving horizontally along the axis of the guide column 16, and compresses one side of the spring three 18 and stretches the other side of the spring three 18, at the same time, drives the shock-absorbing plate 19 to move, through the clamping groove 22 and the clamping and fitting of the abutment column 21, pushes the abutment column 21, the bottom frame 20 and the telescopic column 113 down, and drives the spring two 112 to compress, so that the longitudinal displacement thrust of the shock-absorbing plate 19 is consumed in the clamping and fitting and disengaging of the abutment column 21 and the clamping groove 22;

[0051] Finally, after the shock disappears, the rack 17 is reset under the action of the spring three 18, and drives the gear 12 to rotate back, at the same time, the counterweight block two 15 and the counterweight block one 9 generate magnetic attraction, drive the counterweight block two 15, the support column 14 and the hinge block 13 to reset.
