Description

Technical Field

[0001] This utility model belongs to the field of coupling technology, specifically a coupling resistant to lateral impact. Background Technology

[0002] Couplings, also known as couplings, are mechanical components used to firmly connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. However, existing couplings have a simple structure and generally consist of two halves, namely two half couplings, which are connected to the driving shaft and driven shaft respectively. This makes the couplings prone to damage when subjected to lateral impacts. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a coupling that is resistant to lateral impact, which effectively solves the problem that couplings are easily damaged when subjected to lateral impact.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a coupling resistant to lateral impact, comprising two half-couplings, the two half-couplings being symmetrically arranged and fitted together, and a protective mechanism being provided between the two half-couplings;

[0005] The protective mechanism includes two annular frames, which are fixed to the outside of the two half-couplings respectively. Multiple sliders and inner blocks are provided at equal angles inside the two annular frames. A U-shaped frame is provided between the sliders and inner blocks. A rubber stress plate is fixedly connected to the outside of the U-shaped frame.

[0006] Preferably, multiple inner rods are fixedly connected at equal angles inside the two annular frames, and the slider and inner block are respectively movably sleeved on the outer side of the corresponding inner rod. A buffer spring is fixedly connected between the slider and the inner block and the corresponding annular frame, and the buffer spring is sleeved on the outer side of the corresponding inner rod.

[0007] Preferably, the U-shaped frame is fixedly connected to the slider, a positioning block is fixedly connected to the outer side of the U-shaped frame, and a positioning groove is provided on the side of the inner block near the U-shaped frame, into which the positioning block is inserted.

[0008] Preferably, annular rubber plates are fixedly connected to the outer sides of both half-couplings, and the two annular rubber plates are located between two annular frames.

[0009] Preferably, the inner side of the U-shaped frame is symmetrically fixedly connected with two mounting columns, and each mounting column is provided with an elastic ball at one end near the half coupling, and the two elastic balls abut against two annular rubber plates respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the cooperation between the U-shaped frame, positioning block, positioning groove, inner block, slider and inner rod, when the entire coupling is subjected to lateral impact, the impact force acts directly on the rubber force plate to deform it, and at the same time the buffer spring deforms, and under the action of the elastic force of the rubber force plate and the buffer spring, the impact force is partially absorbed, thereby playing a buffering role and preventing the entire coupling from being damaged when subjected to lateral impact;

[0012] 2. This new type of coupling, through the cooperation between the U-shaped frame and the mounting column, allows the elastic ball to move and collide with the annular rubber plate when the rubber bearing plate is impacted. At the same time, both the elastic ball and the annular rubber plate deform, and the impact force is further buffered under the action of the elasticity of the elastic ball and the annular rubber plate, thus protecting the entire coupling.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figure 1 The present invention relates to a coupling resistant to lateral impact, comprising two half-couplings 1, which are symmetrically arranged and fitted together, and a protective mechanism 2 is provided between the two half-couplings 1.

[0023] Specifically, by Figure 2-5 The protective mechanism 2 includes two annular frames 201, which are respectively fixed to the outer sides of the two half-couplings 1. Multiple sliders 205 and inner blocks 208 are provided at equal angles inside the two annular frames 201. A U-shaped frame 203 is provided between the sliders 205 and the inner blocks 208. A rubber force-bearing plate 209 is fixedly connected to the outer side of the U-shaped frame 203. Multiple inner rods 207 are fixedly connected at equal angles inside the two annular frames 201. Each is movably sleeved on the outside of the corresponding inner rod 207. A buffer spring 204 is fixedly connected between the slider 205 and the inner block 208 and the corresponding annular frame 201. The buffer spring 204 is sleeved on the outside of the corresponding inner rod 207. The U-shaped frame 203 is fixedly connected to the slider 205. A positioning block 2011 is fixedly connected to the outside of the U-shaped frame 203. A positioning groove 2012 is provided on the side of the inner block 208 near the U-shaped frame 203. The positioning block 2011 is inserted into the positioning groove 2012.

[0024] In use, when the two half-couplings 1 are connected and fixed, the positioning block 2011 is inserted into the positioning groove 2012. When the entire coupling is subjected to a lateral impact, the impact force acts directly on the rubber force plate 209, causing the rubber force plate 209 to deform. Then, the U-shaped frame 203 drives the slider 205 and the inner block 208 to slide along the two corresponding inner rods 207 respectively. At the same time, the buffer spring 204 deforms and absorbs part of the impact force under the action of the elastic force of the buffer spring 204 and the rubber force plate 209, thereby playing a buffering role and finally preventing the entire coupling from being damaged when subjected to a lateral impact.

[0025] Specifically, by Figure 3-4As shown, annular rubber plates 202 are fixedly connected to the outer sides of the two half-couplings 1. The two annular rubber plates 202 are located between the two annular frames 201. Two mounting columns 2010 are symmetrically fixedly connected to the inner side of the U-shaped frame 203. Each of the two mounting columns 2010 has an elastic ball 206 at one end near the half-coupling 1. The two elastic balls 206 abut against the two annular rubber plates 202 respectively.

[0026] In use, when the impact force acts directly on the rubber bearing plate 209, it drives the U-shaped frame 203 to move and moves the two mounting columns 2010. At the same time, the two elastic balls 206 impact the two annular rubber plates 202 respectively. Both the elastic balls 206 and the annular rubber plates 202 deform, thereby further buffering the impact force under the elastic force of the elastic balls 206 and the annular rubber plates 202, and finally protecting the entire coupling.
