Abstract

The utility model discloses a kind of novel measurements to follow closely, including wedging nail, connector and head of a nail body, and circular hole is provided on the connector, and the wedging nail is fixed by circular hole and connector, and the head of a nail body engages connection with connector.The utility model passes through setting connector, wedging nail is connected with head of a nail body, the hardness that ground generates is damaged when connector can prevent from hammering into, so that the wedging ability of the novel measurement nail greatly improves, various ground can be wedged, meanwhile surface marker part not will receive the influence that the tools such as hammer tap wedge timesharing, to ensure that the accurate, clear, intact, durable of surface marker.

Description

A kind of novel measurement nail

Technical field

The utility model relates to engineering measurement field, specifically a kind of novel measurement nail.

Background technique

Engineering survey real training is the important link that colleges and universities' relevant speciality carries out measurement education, before one for measuring real training The condition of mentioning is: measurement control point is laid in campus.Currently, measuring the main laying form at control point in colleges and universities are as follows: in pitch Nail measurement nail, follows closely cement nail on cement pavement on road surface.The shortcomings that measurement nail is: wedging ability is poor；The shortcomings that cement nail Be: surface marker is poor；The common drawback of the two is: direct hammer action of the head of a nail by hammer gets rusty easily.

In view of this, the applicant provides a kind of novel measurement nail, thus this case generates.

Utility model content

The utility model provides a kind of novel measurement nail for preventing ground surface damage.

In order to achieve the above objectives, the concrete scheme of the utility model is as follows:

A kind of novel measurement nail, including wedging are followed closely, connector and head of a nail body, are provided with circular hole on the connector, described Wedging nail is fixed by circular hole and connector, and the head of a nail body engages connection with connector.

Preferably

The connector plane is circle, and the connector edge is equipped with groove and several notches；

The head of a nail body includes hollow cylinder, protruding part and the head of a nail, and the head of a nail plane is circle, the head of a nail bottom surface It is provided with hollow cylinder, is provided with several protruding parts on the outside of the hollow cylinder, several described protruding parts and several A notch adaptation.

For convenience of identification, target cross is carved in the head of a nail upper surface.

To improve hardness and preventing from being corroded, the wedging nail, connector and head of a nail body material are stainless steel.

The utility model is connected by setting connector, by wedging nail with head of a nail body, when connector can prevent from hammering into over the ground The hardness damage that face generates can wedge various ground so that the wedging ability of the novel measurement nail greatly improves, meanwhile, table Face character portion not will receive the influence that the tools such as hammer tap wedge timesharing, to ensure that the accurate, clear of surface marker It is clear, intact, durable.

The utility model is further elaborated below by way of Detailed description of the invention and specific embodiment.

Label declaration

Wedging nail 1, connector 2, groove 21, notch 22, circular hole 23, head of a nail body 3, hollow cylinder 31, protruding part 32, nail Cap 33.

Specific embodiment

Embodiment 1

A kind of novel measurement nail, as shown in Figure 1, including wedging nail 1, connector 2 and head of a nail body 3, three is by high intensity Stainless steel is made.

The 1 nail body of wedging nail is elongated, convenient for squeezing into the ground such as pitch, cement.2 plane projection of connector is circle Shape is followed closely 1 there are circular hole 23 in the center point convenient for wedging and is extended there through, and then connector 2 is fixed on the ground；The wedging nail 1 is fixed by circular hole 23, and the head of a nail body 3 engages connection with connector 2.

Embodiment 2

As shown in figures 1 to 6, other as described in Example 1, are distinguished and are that 2 plane projection of connector is circle, described Connector edge is set there are four groove 21 and four notches 22,

The head of a nail body 3 is by hollow cylinder 31, protruding part 32 and the head of a nail 33 is integrated poured forms, 33 plane of the head of a nail It is projected as circle, 33 bottom surface of the head of a nail is provided with hollow cylinder 31, and there are four convex for setting on the outside of the hollow cylinder 31 Part 32 out, four protruding parts 32 and four cooperations of notch 22 are dynamically embedded into connector 2, and rear rotation head of a nail body 3 makes convex Part 32 blocks and in the groove 21 of connector 2 out, so that connector 2 and head of a nail body 3 are fixed.It carves 33 upper surface of the head of a nail There is target cross.The utility model separates the wedging part that traditional measurement is followed closely and surface marker part, and with connector by two Person connects, so that the wedging ability of the novel measurement nail greatly improves, can wedge various ground, meanwhile, surface marker Part not will receive the influence that the tools such as hammer tap wedge timesharing, to ensure that the accurate, clear, complete of surface marker It is good, durable.

Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection scope it It is interior.
