The oil cylinder drives the swing arm to enable the sealing door to translate and rotate, and the sealing door is opened and closed. After the sealing door is closed, the oil cylinder contracts to tightly press the sealing rubber strip at the sealing door, so that garbage scattering and sewage leakage are eliminated. Although the structure can realize the pressing force on the sealing rubber strip, the hydraulic oil cylinder has the problem of internal leakage, so that the sealing door and the rear door cannot be always kept in a tight sealing state, the pressing force is loosened due to the vibration of the box body in the transportation process, the sealing performance of the sealing door cannot be completely guaranteed, and sewage leakage is caused.
The other is a manual locking structure, as shown in fig. 2, the left side of the sealing door is hinged on the rear door of the dustbin, and the right vertical beam is provided with two shaft sleeves which are fixed up and down.

The opening and closing locking device of the sealing door 4 of the garbage can avoids the locking hook groove position of the garbage can body 1 after the sealing door 4 is opened, the operation of locking the garbage can of the garbage compressor is not influenced, and the garbage feeding and the unloading operation of the garbage can body 1 at the rear door 2 are not influenced. And the opening and closing locking device of the dustbin sealing door 4 has simple structure, reasonable layout and convenient operation, meets the requirements of sealing and leakage prevention by clamping garbage at the position of the shielded dustbin back door 2, and has reliable performance.
Specifically, in this embodiment, as shown in fig. 3, the front end of the swing arm 6 is hinged to the garbage can 1, the rear end of the swing arm is hinged to the lower end of the sealing door 4, and when the swing arm 6 and the rocker 3 descend to the right position, the sealing door 4 compresses the sealing rubber strip 5 against the frame of the rear door 2. The bottom of the sealing door 4 is fixed with a hook pin 7 which is hooked and locked by a hook plate 8, the middle position of the hook plate 8 is hinged on a lock hook seat 9, and the front end is hinged on a connecting rod 10. The rear end of the hook plate 8 is provided with an arc hook and is matched with the hook pin 7 of the sealing door 4 to lock the sealing door 4. The position of lock hook seat 9 and hook pin 7 is on same water flat line, and behind the hook plate 8 locking, hook pin 7 is used in the pulling force direction that 8 levels of hook plate are backward and is close lock hook seat 9, and the pulling force is balanced by the reaction force of rubbish box 1 basically, can satisfy the condition of 8 auto-locks of hook plate, and locking is more reliable.
Furthermore, the swing rod 11 is hinged on a hinged seat 12, the hinged seat 12 is fixed on the box body 1, and a limiting plate 13 is fixed on the hinged seat 12. The short arm end of the swing rod 11 is hinged with the connecting rod 10, the long arm end of the swing rod 11 is hinged with the lower end of the oil cylinder 14, and the upper end of the oil cylinder 14 is hinged with the swing arm 6. The swing rods 11 with different arm lengths enable the contraction force of the oil cylinder 14 to increase the acting force of the short arm sides of the swing rods 11 on the hook plate 8 through the lever effect, and a large locking force is generated on the sealing door 4 through a small oil cylinder force.
Furthermore, the rubber bump 15 is installed on a supporting seat 16 fixed on the garbage can 1, and the front end of the rocker 3 is hinged on the supporting seat 16. The connecting rod 10 is composed of a first connecting fork 17 with left-hand threads, a left-hand nut 18, a pull rod 19 with left-hand threads and right-hand threads, a right-hand nut 20 and a second connecting fork 21 with right-hand threads from top to bottom. Through rotatory pull rod 19, can freely adjust the vertical distance of pin joint about the connecting rod 10 to the locking dynamics of adjustment hook plate 8 to gib pin 7, sealing door 4 compresses tightly the degree to joint strip 5 promptly. When the sealing door 4 is in a closed and locked state, the swing arm 6 is pulled downwards by the contraction force of the oil cylinder 14, and meanwhile, the hook end of the hook plate 8 is lifted upwards through the connecting rod 10. The joint strip 5 is compressed tightly under the combined action of the downward pulling force of the swing arm 6 and the forward locking force of the hook plate 8 under the self weight of the sealing door 4, so that the sealing performance is realized.
Specifically, in this embodiment, as shown in fig. 4, the force arm of the hinge point of the swing arm 6 on the box body by the gravity of the sealing door 4 is much larger than the force arm of the hinge point of the swing arm 6 on the box body by the oil cylinder 14, and because the force required for unlocking the hook plate 8 is smaller than the force required for opening the sealing door 4, the driving oil cylinder 14 extends out, the oil cylinder 14 rotates the swing rod 11 along the hinge point, and drives the connecting rod 10 to move upwards to pull up the front end of the hook plate 8, and the hook plate 8 rotates around the hinge point at the position of the hook seat 9, and disengages from the hook pin 7 to unlock the hook plate 8. After one side of the long arm of the swing rod 11 moves to be in contact with the limiting plate 13, the swing rod 11 and the connecting rod 10 do not move any more, and the hook plate 8 is completely unlocked. Since the reaction force of the oil cylinder 14 which initially rotates the swing lever 11 is not sufficient to support the swing arm 6, the swing arm 6 and the sealing door 4 do not move during the unlocking of the hook plate 8.
Further, swing arm 6, rocker 3, sealing door 4 constitute four-bar linkage with rubbish box 1, and when hydro-cylinder 14 continued to stretch out, because of limiting plate 13's limiting displacement, pendulum rod 11 no longer rotated, and hydro-cylinder 14 can only upwards stretch out, drives swing arm 6 around the pivot point swing of swing arm 6 on the box, and swing arm 6 swings and drives sealing door 4 upwards through the rotation of rocker 3 jointly and open. After the oil cylinder 14 is extended to the right position, as shown in fig. 5, the top surface of the swing arm 6 just contacts with the top surface of the rubber bump 15, and the sealing door 4 is completely opened. The rubber collision block 15 is arranged on the supporting seat 16 and used for limiting and buffering the swing arm 6 and reducing the impact force of the swing arm 6, so that the sealing door 4 is kept stable under the interaction of the supporting force of the oil cylinder 14 and the counter force of the rubber collision block 15 after being opened. The opening and closing locking device of the sealing door of the garbage can avoids the locking hook groove position of the garbage can body 1 after the sealing door 4 is opened, the operation of locking the garbage can of the garbage compressor is not influenced, and the garbage feeding and the box body discharging operation at the position of the rear door 2 are not influenced.
On the contrary, the oil cylinder 14 can realize descending closing and locking of the sealing door 4 after being retracted, and the closing and locking process is opposite to the unlocking and opening process. The garbage can locking mechanism has the advantages that the single oil cylinders symmetrically arranged on two sides of the garbage can complete the coherent action of driving the sealing door to open and close and lock within a stroke range, the opening and closing and locking actions of the sealing door are not interfered with each other, the hook plate is firmly locked, the locking tightness degree is adjustable, the problem of sewage leakage at the gap between the rear door of the garbage can and the sealing door is well solved, meanwhile, the compression force of the sealing door acts on the rear door, and the locking tightness between the rear door and the garbage can be improved. The opening and closing locking device for the dustbin sealing door has the advantages of simple structure, low manufacturing cost, convenience in operation and strong controllability, and is suitable for the dustbin sealing door.
Further, this embodiment still relates to the dustbin, and wherein the principle and the effect of dustbin are the same with the locking device that opens and close of foretell dustbin sealing door, do not give unnecessary details here.
