Description

Technical Field

[0001] The utility model belongs to the field of hydraulic breakers, and relates to a new type of breaker, in particular to a structure of a rod pin for a new type of breaker. Background Technique

[0002] As an indispensable tool in engineering construction, the breaker is widely used in scenarios such as demolishing buildings, excavating stones and rocks. Its working principle is mainly to drive the rod to vibrate rapidly through hydraulic pressure to break hard materials. However, under the action of high-frequency vibration and huge impact force, the traditional rod pin structure is easily damaged, resulting in a decline in the performance of the breaker and even causing safety accidents. Summary of the Invention

[0003] The purpose of the utility model is to provide a structure of a rod pin for a new type of breaker aiming at the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A structure of a rod pin for a new type of breaker, including a breaker housing and a hammer core assembly. A front cylinder body is arranged on the hammer core assembly, and a rod is installed inside the front cylinder body. It is characterized in that two cross pins are horizontally distributed between the breaker housings, and the two cross pins are arranged one above the other. At least one flat pin is arranged between the cross pins, and shock pads for shock absorption are arranged on one side or both sides of the flat pin.

[0005] In the above structure of a rod pin for a new type of breaker, the shock pad is made of non-metallic material.

[0006] In the above structure of a rod pin for a new type of breaker, a threaded hole for easy disassembly and assembly is opened at the center of the shock pad.

[0007] Compared with the prior art, the structure of the rod pin for the new type of breaker of the present utility model:

[0008] 1. By adding the design of shock pads, the vibration and impact force during the impact process of the rod pin structure are effectively alleviated, and the overall performance and reliability of the breaker are improved.

[0009] 2. The design of the shock sleeve reduces the stress on the rod pin structure and other components, reduces the risk of wear and damage, and thus extends the service life of the breaker.

[0010] 3. The shock pad is wear-resistant, low in cost, and extends the replacement cycle of the cross pin. Description of the Drawings

[0011] Figure 1 It is a cross-sectional view of the structure of the rod pin for the new type of breaker.

[0012] Figure 2It is a schematic diagram of a shock pad for a novel breaker rod pin structure.

[0013] In the figure, 1. breaker housing; 2. hammer core assembly; 3. front cylinder block; 4. rod; 5. cross pin; 6. flat pin; 7. shock pad; 8. threaded hole. Detailed implementation mode

[0014] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0015] As Figure 1 , Figure 2 shown, the novel breaker rod pin structure includes a breaker housing 1 and a hammer core assembly 2. A front cylinder block 3 is provided on the hammer core assembly 2 and a rod 4 installed inside the front cylinder block 3. Two cross pins 5 are horizontally distributed between the breaker housings 1, and the two cross pins 5 are placed one above the other. At least one flat pin 6 is provided between the cross pins 5. A shock pad 7 for shock absorption is provided on one side or both sides of the flat pin 6. The shock pad 7 is stably installed between the cross pin 5 and the flat pin 6 to reduce the vibration and impact force generated during the impact of the breaker.

[0016] Further details, the shock pad 7 is made of non-metallic material, and the shock pad 7 is circular, rectangular and square.

[0017] Further details, a threaded hole 8 for easy disassembly and assembly is provided at the center of the shock pad 7.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although terms such as breaker housing 1, hammer core assembly 2, front cylinder block 3, rod 4, cross pin 5, flat pin 6, shock pad 7, threaded hole 8, etc. are used more in this article, the possibility of using other terms is not excluded.
