Detailed implementation mode

[0032] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0033] Please refer to Figures 1-6 , the present utility model details the above technical solutions through the following embodiments:

[0034] A dust and noise reduction device for a breaker, comprising:

[0035] A connection unit 5, detachably installed below the breaker body 1; As shown in the structure of Figure 4 , Figure 5 , the connection unit 5 includes an inner cylinder 51 provided with a lobe 52, and the inner cylinder 51 is provided with an external thread structure.

[0036] A limiting unit 8, detachably installed below the connection unit 5; As shown in the structure of Figure 4 , Figure 5 , the limiting unit 8 includes an outer sleeve 81 provided with an internal thread groove 811, the bottom of the outer sleeve 81 is provided with a ring block 82, and the inner cylinder 51 is threadedly installed at the thread groove 811;

[0037] A protective cylinder 2, slidably installed on the limiting unit 8, and a sponge inner pad 3 and a noise reduction plate 4 are sequentially arranged on the inner wall of the protective cylinder 2 from inside to outside; The protective cylinder 2 includes a top plate 21 provided with a through hole 211, and the through hole 211 is used for inserting the outer sleeve 81.

[0038] It should be noted that after the limiting unit 8 and the connection unit 5 are threadedly connected, the up and down movement of the protective cylinder 2 can be limited based on the lobe 52 and the ring block 82. When installing, the limiting unit 8 needs to be inserted into the through hole 211, and vice versa when disassembling, to prevent the protective cylinder 2 from falling off.

[0039] It is worth explaining that when the breaker body 1 is operating, the hammer head vibrates. To protect the device and avoid hard contact with the ground, there is also a setting as shown in Figures 1-4The two elastic units, the elastic unit includes a plug rod 6 arranged between the connecting unit 5 and the protective cylinder 2, and a spring 7 sleeved on the plug rod 6. The plug rod 6 is threadedly installed at the lug 52, and a jack 212 for inserting the plug rod 6 is provided on the top plate 21. The plug rod 6 is inserted into the jack 212 and will not collide.

[0040] In order to facilitate the quick alignment and installation of the plug rod 6 and the spring 7, a limit protrusion 812 is provided on the outer wall of the outer sleeve 81 in this embodiment.

[0041] It should be noted that, in order to facilitate the disassembly and replacement of the sponge inner pad 3 and the noise reduction plate 4 with dust reduction and noise reduction functions, as Figures 4-6 shown in the structure, a clamping cavity 201 is provided on the wall of the protective cylinder 2, a guide hole 202 is provided on the inner wall of the clamping cavity 201, and a socket is provided above the clamping cavity 201. The socket is used for inserting the sponge inner pad 3 and the noise reduction plate 4.

[0042] The working principle of the dust reduction and noise reduction device of the breaker in this embodiment is as follows: First, insert the limiting unit 8 into the protective cylinder 2 from bottom to top through the through hole 211, then threadedly install the connecting unit 5 from above, and then threadedly install the plug rod 6 at the lug 52 so that the plug rod 6 is inserted into the jack 212, and a spring 7 is sleeved on the plug rod 6. The spring 7 can make the protective cylinder 2 tend to move downward. When the breaker body 1 operates, the protective cylinder 2 can move elastically based on the spring 7, which can avoid damaging the cylinder body of the protective cylinder 2. The generated noise can be absorbed by the porous sponge inner pad 3 and the noise reduction plate 4. In order to reduce dust, the sponge inner pad 3 can be soaked. This device has a reliable structure, low cost, and obvious dust reduction and noise reduction effects.

[0043] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0044] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" can explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0045] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
