Description

A locking device for garbage bins and compression bins in a garbage compression station

technical field

The utility model relates to a locking device, in particular to a locking device for a garbage box and a compression box in a garbage compression station.

Background technique

At present, garbage compressors are often used in garbage transfer stations to compress the collected garbage into garbage bins, and then garbage trucks transport the garbage in the garbage bins to landfill plants for processing. When compressing, the garbage bins and garbage compressors are first connected , and lock the two, and then compress. Chinese Utility Model Patent Specification CN203410062U discloses a locking mechanism, including a support, a locking cylinder and a roughly L-shaped locking hook. The support is fixed in the middle of the front end of the side of the compression box. The middle part of the L-shaped lock hook is hinged on the support, the long arm of the L-shaped lock hook protrudes from the front end of the compression box and has a barb, and the end of the short arm of the L-shaped lock hook is hinged with the piston rod of the locking cylinder. The rear end of the locking cylinder block is hinged on the side of the compression box. There are also two problems in the locking mechanism. 1. Due to the manufacturing and installation errors of the joint surface of the box body, there is a deviation in the cooperation between the locking hook and the fastening part on the garbage bin, resulting in locking failure. 2. Due to the thrust of garbage compression , It is difficult to open the locking hook after full load.

Contents of the invention

In order to solve the deficiencies in the prior art, the purpose of the utility model is to provide a simple structure, convenient locking and easy to open garbage compression station garbage box and compression box locking device. In order to achieve the above object, the utility model adopts the following technical solutions:

A locking device for garbage bins and compression boxes at a garbage compression station, which is arranged on both sides of the compression box body, and includes a locking oil cylinder, a support and a locking hook, and the cylinder body and the support of the locking oil cylinder are fixed on the compression box body On both sides, the middle part of the locking hook is connected to the support through a pin shaft. The pin shaft divides the locking hook into a long arm and a short arm. The long arm of the locking hook protrudes from the front end of the compression box and has a barb. The dustbin is provided with a fastening part corresponding to the barb of the locking hook, and the end of the short arm of the locking hook is hinged with the piston rod of the locking cylinder, and the piston rod drives to hook the dustbin tightly. There is a waist-shaped hole on the seat, and the end of the pin shaft on the locking hook is clamped in the waist-shaped hole, and moves along the length direction of the waist-shaped hole, and the part of the pin shaft protruding from the waist-shaped hole is connected with one end of the spring , the other end of the spring is connected to the support, and the elastic tension of the spring connecting the pin shaft is directed towards the direction of the dustbin.

One end of the pin shaft is provided with a shoulder, the diameter of which is slightly larger than the width of the waist-shaped hole, and the other end is provided with a snap ring, the diameter of which is slightly larger than the width of the waist-shaped hole.

The contraction of the piston rod of the oil cylinder drives the locking hook to lock the dustbin, and at the same time, under the action of the pin shaft and the elastic force of the spring clamped in the arc-shaped guide groove, the locking hook retracts inwards and locks the dustbin. The extension of the piston rod drives the locking hook to break away from the dustbin, and at the same time, under the action of the pin shaft clamped in the arc-shaped guide groove and the elastic force of the spring, it opens outwards, and the locking hook releases the dustbin.

The cylinder body of the locking oil cylinder is hinged and fixed on the side of the compression box.

The length direction of the waist-shaped hole and the tension direction of the spring are consistent with the stretching direction of the piston rod.

The utility model adopts the above technical scheme. Driven by the locking oil cylinder, the locking hook moves along the length direction of the waist hole, which avoids the failure of locking due to the existence of manufacturing and installation errors, and prevents sewage from entering the garbage bin and the connection box. Splash or leakage, the spring installed between the pin shaft and the support in the middle of the locking hook is convenient to open the locking hook after the garbage bin is fully loaded, and cooperates with the waist-shaped hole to make the locking and opening process more stable.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Fig. 1 is a structural schematic diagram of a garbage bin and a compression box locking device of a garbage compression station of the present invention;

Fig. 2 is a schematic diagram of the utility model A-A sectional structure.

detailed description

As shown in Figure 1 or Figure 2, the utility model is arranged on both sides of the compression box, which includes a locking oil cylinder 1, a support 2 and a locking hook 3, and the cylinder body 12 and the support 2 of the locking oil cylinder are fixed on the compression box. On both sides of the box body, the middle part of the locking hook 3 is connected to the support 2 through the pin shaft 4. The pin shaft 2 divides the locking hook into a long arm 31 and a short arm 32, and the long arm of the locking hook stretches out and compresses. The front end of the box has a barb, and the garbage bin is provided with a fastening part corresponding to the barb of the locking hook 3, and the end of the short arm 32 of the locking hook is hinged with the piston rod 11 of the locking cylinder. Driven by the piston rod 11 to hook the dustbin, the support is provided with a waist-shaped hole 5, and the end of the pin shaft 4 on the locking hook is engaged in the waist-shaped hole 5, and along the length of the waist-shaped hole 5 Direction moves, and pin 4 stretches out the part of waist-shaped hole 5 and is connected with an end of spring 6, and the other end of spring 6 is connected with support 2, and the elastic tension of spring 6 that connects pin is towards the dustbin direction. One end of the pin 4 is provided with a shoulder 41 whose diameter is slightly larger than the width of the waist hole 5 , and the other end is provided with a snap ring 42 whose diameter is slightly larger than the width of the waist hole 5 . The cylinder body 12 of the locking oil cylinder is hingedly fixed on the side of the compression box. The length direction of the waist-shaped hole 5 and the tension direction of the spring 6 are consistent with the telescopic direction of the piston rod 11 .

The piston rod 11 of the oil cylinder shrinks to drive the locking hook to lock the dustbin, and at the same time, under the action of the pin shaft and spring force clamped in the arc-shaped guide groove, the locking hook 3 is inwardly retracted and locked to the dustbin. The extension of the piston rod 11 of the oil cylinder drives the locking hook to break away from the dustbin, and simultaneously opens outwards under the action of pin shaft and spring force in the arc-shaped guide groove, and the locking hook 3 unclamps the dustbin.

The utility model has a simple structure, through the cooperation of the pin shaft and the waist-shaped hole, the garbage can can still be locked even in the case of installation and manufacturing errors, and the cooperation with the spring facilitates the opening of the garbage box after it is fully loaded, and the locking process is more stable.
