Description

Technical Field

[0001] The utility model relates to the technical field of livestock and poultry breeding equipment, in particular to a tensioning mechanism for an adaptive chain. Background Technique

[0002] Chain drive is a transmission method for cargo transportation. In large-scale farms nowadays, in order to collect eggs more conveniently and quickly, elevators are mostly used to collect eggs. The most common way to collect eggs by an elevator is through chain drive. In chain drive, the cooperation between the chain and the sprocket is particularly important. If the chain is too loose, the transmission cooperation will be poor and the chain is likely to fall off; if the chain is too tight, the chain will be subjected to excessive force and is likely to break. Therefore, a proper chain fit is particularly important. However, the traditional chain drive structure has a fixed size for each section, while the distance between the two sprockets is determined according to the actual situation, and problems are inevitable in the cooperation, which brings great trouble to people. Content of the Utility Model

[0003] In order to overcome the problems that in the process of using the traditional chain structure in daily work, the traditional chain structure has a fixed size for each section, while the distance between the two sprockets is determined according to the actual situation, and problems are likely to occur in the cooperation, affecting the normal transmission of goods.

All the fixed parts of this device adopt a riveting structure, which can greatly improve the installation speed. When one end of the adjusting component is fixed to the connection component, the torsion structure of the adjusting component is in an open state in the natural state, and the torsion structure can be pressed to be in a force-generating state according to the length of the installed chain, so as to tighten the rope.

[0006] As a preference, the connection component includes a connection seat and an arc-shaped frame; the connection seat is arranged below the bracket, and the arc-shaped frame is arranged on one side of the connection seat. During use, the position of the arc-shaped frame is fixed through the connection seat.

[0007] Preferably, the tensioning assembly includes a tongue depressor and a fixing bracket; a tongue depressor is arranged below the connecting seat, a fixing bracket is arranged inside the tongue depressor, and the tongue depressor is made of POM material. During use, the fixing bracket supports the inside of the tongue depressor to prevent the tongue depressor from deforming greatly during use, and the wear resistance of the tongue depressor is improved by the POM material.

[0008] Preferably, the adjusting assembly includes a mounting bracket and a torsion spring; a mounting bracket is arranged inside the tongue depressor, and a torsion spring is arranged outside the mounting bracket. During use, one end of the torsion spring is fixed by the tongue depressor, and the other end of the torsion spring is fixed by the arc-shaped bracket. When the torsion spring is in the natural state, the tongue depressor is in an open state. According to the length of the installed chain, the torsion spring can be compressed to be in a stressed state, thereby driving the tongue depressor to rotate and tighten the rope.

[0009] Preferably, the fixing assembly includes a pin and an opening pin; a pin is arranged inside the connecting seat, and an opening pin is arranged inside the pin.

[0011] Preferably, the installation assembly includes a mounting plate and mounting bolts; a mounting plate is arranged on one side of the bracket, and mounting bolts are arranged inside the mounting plate. During use, the bracket can be installed and fixed on the side plate of the chain device through the mounting plate and the mounting bolts, thereby performing installation and fixing processing on the tensioning mechanism.

[0012] The beneficial effects of the present utility model:

[0013] 1. Compared with the traditional elevator that conveys goods by chain drive, in chain drive, if the chain is too loose, the transmission fit will be poor and it is easy to cause the chain to fall off, while if the chain is too tight, the chain will be subjected to excessive force and it is easy to cause the chain to break. However, the traditional chain structure has a fixed size for each section, while the distance between the two sprockets is determined according to the actual situation, and problems are likely to occur in the cooperation, affecting the normal transmission of goods. In this device, the torsion structure is in an open state in the natural state, and according to the length of the installed chain, the torsion structure can be compressed to be in a stressed state, thereby tightening the rope, realizing the adaptive adjustment of the tension degree of the chain;

[0014] 2. The position of the arc-shaped frame is fixed through the connecting seat, and the inside of the tongue depressor is supported through the fixing frame, thereby preventing the tongue depressor from deforming greatly during use. The connecting seat and the tongue depressor are fixed through the pin and the split pin, thereby fixing the position of the torsion spring. One end of the torsion spring is fixed through the tongue depressor, and the other end of the torsion spring is fixed through the arc-shaped frame. When the torsion spring is in the natural state, the tongue depressor is in the open state. According to the length of the installed chain, the torsion spring can be compressed to be in the force state, thereby driving the tongue depressor to rotate and tighten the rope, and thus using the resilience of the tensioning structure of the device to tighten the chain to ensure that the chain is in the best state, realizing the adaptive adjustment of the tension degree of the chain;

[0015] 3. The bracket can be installed and fixed on the side plate of the chain device through the mounting plate and the mounting bolts, thereby installing and fixing the tensioning mechanism. The bracket and the connecting seat are connected and fixed through the rivets. The installation speed of the device can be improved through the riveting method, which is more convenient than the manual adjustment method. BRIEF DESCRIPTION OF THE DRAWINGS
