Technical Field

[0001] This utility model relates to the field of fixing head technology, and more specifically, it relates to a shock-absorbing fixing head. Background Technology

[0002] A fixing head is nailed to a flat wall surface, which can then be used to connect external objects. Traditional fixing heads use a rigid connection to the wall, which results in a large reaction force under significant impact, easily damaging the external objects connected to them, and the overall effect is unsatisfactory. Therefore, this utility model proposes a shock-absorbing fixing head. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a shock-absorbing fixing head that has the characteristics of impact resistance and good shock absorption effect.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to a shock-absorbing fixing head, which includes fixing nails and reinforcing parts. The reinforcing parts include a central tube, and a number of reinforcing wing plates connected to and extending radially are arranged around the central tube. A fixing retaining ring connected to and close to one end is provided outside the central tube. The fixing pin includes a pin body that passes through a central tube. The central tube is slidably connected to the pin body. One end of the pin body has a pointed tip, and the other end has a tail that restricts axial movement. A retaining spring groove is provided on the outer wall of the pin body. The central tube is located between the tail and the retaining spring groove. An outer retaining spring is embedded in the retaining spring groove. An elastic element is fitted on the pin body, with one end abutting against the outer retaining spring and the other end abutting against the fixing retaining ring.

[0005] The present invention is further configured such that one end of the reinforcing wing plate is connected to the fixing retaining ring.

[0006] The present invention is further configured such that the other end of the reinforcing wing plate has a chamfer.

[0007] The present invention is further configured such that the elastic element is a compression spring.

[0008] The present invention is further configured such that the included angle between two adjacent reinforced wing plates is equal.

[0009] In summary, the present invention has the following beneficial effects: The shock-absorbing fixing head involved in the present invention, by fitting a reinforcing member that slides axially onto a fixing nail connected to the wall, and with the addition of an elastic element and an external snap spring, can achieve axial shock absorption function, buffering foreign objects installed on the reinforcing member, resisting impact, with good shock absorption effect, complete overall function, and strong practicality.

Detailed Implementation

[0011] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0012] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0013] Example 1 See Figures 1 to 4 As shown, the shock-absorbing fixing head involved in this embodiment includes a fixing nail 100 and a reinforcing member 200. The reinforcing member 200 includes a central tube 201. Several reinforcing wing plates 202 connected to and extending radially are arranged around the central tube 201. A fixing retaining ring 203 connected to and near one end is provided on the outside of the central tube 201. The fixing nail 100 includes a nail body 101 that passes through a central tube. The central tube 201 is slidably connected to the nail body 101. One end of the nail body 101 has a pointed tip 102 and the other end has a tail 103 that restricts axial movement. A retaining spring groove 104 is provided on the outer wall of the nail body 101. The central tube 201 is located between the tail 103 and the retaining spring groove 104. An outer retaining spring 105 is embedded in the retaining spring groove 104. An elastic element 106, which is a compression spring, is sleeved on the nail body 101, with one end abutting against the outer retaining spring and the other end abutting against the fixing retaining ring.

[0014] Furthermore, the included angle between two adjacent reinforcing wing plates 202 is equal.

[0015] In this embodiment, due to the axial limitation of the outer retaining spring 105, the fixing nail 100 connected to the wall can only be inserted to the position of the outer retaining spring 105, so that the reinforcement 200 floats outside the wall. When the external object is connected to the reinforcement 200, it can move together with the reinforcement 200. When the external object is squeezed, the force can be transmitted to the elastic element 106, which can achieve a buffering and force-relieving effect while compressing it, so as to realize the shock absorption function.

[0016] Example 2 See Figures 1 to 4 As shown, the shock-absorbing fixing head involved in this embodiment is further configured, based on embodiment 1, that one end of the reinforcing wing plate 202 is connected to the fixing retaining ring 203, and the other end has a chamfer (not marked).

[0017] In this embodiment, a chamfer is provided at the end of the reinforcing wing plate 202 facing away from the pointed end, which serves as an installation guide when connecting to external objects.

[0018] The shock-absorbing fixing head involved in this utility model has an axially sliding reinforcement component installed on a fixing nail connected to the wall. With the addition of an elastic element and an external retaining spring, the reinforcement component can achieve axial shock absorption, buffering foreign objects installed on the reinforcement component, resisting impact, and providing excellent shock absorption. The overall function is complete and highly practical.
