The guide rods on the fascia guns in the prior art are directly slidably set in the guide sleeve, resulting in a large friction resistance when the guide rod reciprocates along the guide sleeve, and the noise generated is also large, affecting the user experience. Utility Model Content

[0003] The utility model provides a fascia gun equipped with a guide sleeve capable of reducing noise, aiming to solve the problem that the guide sleeve on the fascia gun in the prior art generates large friction resistance on the guide rod, resulting in large noise.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A fascia gun equipped with a guide sleeve capable of reducing noise comprises a housing, a guide rod, a guide sleeve and a power assembly arranged in the housing, a massage piece is arranged outside the housing, an output end of the power assembly is connected to the guide rod, and the other end of the guide rod passes through the housing and is connected to the massage piece;

[0006] The guide sleeve is provided with an annular sleeve connection portion which is sleeved on the outside of the guide rod, the inner side surface of the annular sleeve connection portion is arc-shaped, and a connecting portion is provided between the outer wall of the annular sleeve connection portion and the inner wall of the guide sleeve; when the guide rod reciprocates along the annular sleeve connection portion driven by the power component, the annular sleeve connection portion swings back and forth along the inner wall of the guide sleeve driven by the friction force of the guide rod.

[0007] A further solution: the connecting portion is made of elastic material.

[0008] Based on the above technical solution: the connecting part is elastic, so that the annular sleeve part has the ability to restore deformation when reciprocating, and also facilitates the annular sleeve part to smoothly reciprocate along the inner wall of the guide sleeve driven by the friction force of the guide rod.

[0009] A further solution: the guide sleeve, the connecting portion and the annular sleeve connecting portion are integrally formed.

[0010] Based on the above technical solution: the one-piece molding setting is convenient for processing and manufacturing.

[0011] A further solution: the guide sleeve, the connecting part and the annular sleeve connecting part are all made of rubber or silicone.

[0012] Based on the above technical solution: the rubber or silicone material can not only provide a certain support to the guide rod, but also has wear resistance and can extend the service life.

[0013] A further solution: the connecting portion is an annular sheet.

[0014] Based on the above technical solution: when the connecting part is set as an annular sheet, the deformation ability is good, and it is more convenient for the annular sleeve connection part to swing back and forth along the inner wall of the guide sleeve under the friction of the guide rod.

[0015] A further solution: the connecting portion is arranged perpendicular to the inner side wall of the guide sleeve.

[0016] A further solution: the cross section of the annular sleeve portion is D-shaped or semicircular.

[0017] The beneficial effects of the utility model are:

[0018] The utility model provides an annular sleeve connection portion which is sleeved on the outside of a guide rod in the guide sleeve, and the cross section of the annular sleeve connection portion is configured to be arc-shaped, so that when the guide rod reciprocates along the annular sleeve connection portion, the friction force generated between the guide rod and the annular sleeve connection portion will cause the annular sleeve connection portion to swing. Due to the reciprocating swing of the annular sleeve connection portion, it forms a rolling contact match with the outer side wall of the guide rod, thereby reducing the friction resistance of the annular sleeve connection portion to the guide rod, thereby reducing the friction noise generated between the annular sleeve connection portion and the guide rod.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0027] like Figures 1 to 4 As shown, this embodiment provides a fascia gun equipped with a guide sleeve 1 capable of reducing noise, comprising a housing 5, a guide rod 4, a guide sleeve 1 and a power assembly arranged in the housing 5, a massage piece is arranged outside the housing 5, an output end of the power assembly is connected to the guide rod 4, and the other end of the guide rod 4 passes through the housing 5 and is connected to the massage piece;

[0028] The guide sleeve 1 is provided with an annular sleeve connection portion 3 which is sleeved on the outside of the guide rod 4. The inner side surface of the annular sleeve connection portion 3 is arc-shaped, and a connecting portion 2 is provided between the outer wall of the annular sleeve connection portion 3 and the inner wall of the guide sleeve 1; when the guide rod 4 reciprocates along the annular sleeve connection portion 3 driven by the power component, the annular sleeve connection portion 3 swings back and forth along the inner wall of the guide sleeve 1 driven by the friction force of the guide rod 4.

[0029] Specifically, when the guide rod 4 extends outward from the shell body 5, the friction force generated between it and the annular sleeve joint 3 will cause the annular sleeve joint 3 to swing outward along the inner wall of the guide sleeve 1; when the guide rod 4 retracts into the inner side of the shell body 5, the friction force generated between it and the annular sleeve joint 3 will cause the annular sleeve joint 3 to swing inward along the inner wall of the guide sleeve 1; during this process, since the cross-section of the annular sleeve joint 3 is arc-shaped, the reciprocating swinging motion generated by it forms a rolling contact with the outer wall of the guide rod 4, thereby reducing the friction resistance to the guide rod 4.

[0030] The cross section of the annular sleeve portion 3 can be set to be D-shaped or semicircular.

[0031] In this embodiment, the connecting portion 2 is preferably made of an elastic material. Specifically, the guide sleeve 1, the connecting portion 2 and the annular sleeve connection portion 3 are all made of rubber or silicone.

[0032] In order to facilitate processing, the guide sleeve 1, the connecting portion 2 and the annular sleeve connection portion 3 are integrally formed.

[0033] In this embodiment, in order to facilitate the annular sleeve connection portion 3 to swing back and forth along the inner wall of the guide sleeve 1, the connection portion 2 is preferably formed as an annular sheet. Specifically, in the initial state, the connection portion 2 is arranged perpendicular to the inner wall of the guide sleeve 1.

[0034] Working principle description:

[0035] like Figure 4 As shown, when the guide rod 4 extends outward from the shell body 5, the friction force generated between it and the annular sleeve joint 3 will cause the annular sleeve joint 3 to swing outward along the inner wall of the guide sleeve 1; when the guide rod 4 retracts into the inner side of the shell body 5, the friction force generated between it and the annular sleeve joint 3 will cause the annular sleeve joint 3 to swing inward along the inner wall of the guide sleeve 1; during this process, since the cross-section of the annular sleeve joint 3 is arc-shaped, the reciprocating swinging motion generated by it forms a rolling contact fit with the outer wall of the guide rod 4, thereby reducing the friction resistance to the guide rod 4.

[0036] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
