Description

Novel bolt

Technical Field

The utility model particularly relates to a novel bolt.

Background

The bolts are used for connecting and fastening the effect. The existing bolt driving modes are many, such as a straight slot, a cross slot, a square slot, an inner hexagon, an outer hexagon and the like, corresponding driving tools are different, the head of a common bolt is the outer hexagon, the inner hexagon is arranged on the top surface of the common bolt, and the driving effect can be achieved by using another tool on the premise of lacking the corresponding tool.

In the existing bolt driving, problems can occur in the combination process, and dual-purpose or multi-purpose effects cannot be achieved, particularly in the matching process of the cross groove and the square groove, dual-purpose matching is difficult to achieve.

Disclosure of Invention

The utility model mainly solves the technical problem of providing a novel bolt.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the novel bolt comprises a head, wherein the head is provided with a square groove and a cross groove, the cross groove comprises a transverse groove and a longitudinal groove, the transverse groove is vertically communicated with the longitudinal groove, the transverse groove transversely penetrates through two sides of the head, and an intersection exists at the joint of the square groove, the longitudinal groove and the transverse groove.

Compared with the prior art, if the cross groove is overlapped with the square groove, the cross groove is limited in size, the joint of the cross groove and the square groove is easily worn in the matching process of the screwdriver bit or the screwdriver bit in the driving process, and after multiple use, the slipping phenomenon can occur, so that the cross groove cannot be used continuously. By adopting the structure, the size of the transverse groove is increased, so that the contact area between the screwdriver bit or screwdriver bit and the cross groove in the matching process is larger, and the structure similar to two halves is formed through the transverse groove, so that the head part forms a certain elastic effect, a certain twisting effect is formed in the rotation driving process, a buffer is formed, and the cross groove is not easy to wear, so that the service life is prolonged.

Wherein, be equipped with first guide surface on the junction of horizontal groove and square groove.

The arrangement of the first guide surface plays a guiding effect, so that the screwdriver bit or screwdriver bit can enter more easily, and meanwhile, the contact area between the screwdriver bit and the screwdriver bit is increased.

Wherein, the junction of longitudinal groove and square groove is last to be equipped with the second guide surface.

The arrangement of the second guide surface plays a role in guiding, so that the screwdriver bit or screwdriver bit can enter more easily, and meanwhile, the contact area between the screwdriver bit and the screwdriver bit is increased.

Wherein, be equipped with the stopper on the square groove.

The setting of stopper cooperates with the screwdriver bit or the screwdriver bit of drive square groove, forms spacing driven effect.

The limiting blocks are positioned on the bottom surface of each corner of the square groove.

Wherein, be equipped with the constant head tank on the head, the constant head tank is located the below of square groove, and constant head tank and square groove intercommunication.

Through the setting of constant head tank, form the fixed effect of location, ensure concentricity, improve the driving effect.

Detailed Description

Example 1:

referring to fig. 1-2, a novel bolt includes a head 100.

In this embodiment, the shaft portion of the bolt is provided with external threads, which is a prior art, so that the description of this embodiment is omitted and only the head portion 100 is described.

The head 100 is cylindrical, and is provided with a square groove 1, a cross groove 2 and a positioning groove 3 on the top surface.

The cross slot 2 includes a transverse slot 21 and a longitudinal slot 22, the transverse slot 21 and the longitudinal slot 22 being in vertical communication, i.e. both forming a cross-like structure for cooperation with a cross screwdriver bit or cross screwdriver bit, thereby achieving a driving effect.

The lateral slots 21 extend transversely through the ends of the head 100, i.e. so that the top surface of the head 100 forms two areas which are partially spaced in depth, thus forming a portion of the resilience. Here, a first guide surface 211 is provided at the junction of the transverse groove 21 and the square groove 1. The provision of the first guide surface 211 provides a guiding effect for easier entry of the screwdriver bit or bits while also increasing the contact area therebetween.

The longitudinal grooves 22 are disposed longitudinally, in this embodiment, the longitudinal grooves 22 do not penetrate through the two ends of the head 100, so that the longitudinal grooves 22 and the transverse grooves 21 form a long-short vertical connection. The connection of the longitudinal groove 22 and the square groove 1 is provided with a second guiding surface 221. The provision of the second guide surface 221 provides a guiding effect that allows for easier entry of the screwdriver bit or bits while also increasing the contact area therebetween. It should be noted that, the first guiding surface 211 extends from the bottom surface of the transverse slot 21 toward the square slot 1, the second guiding surface 221 extends from the top surface of the head 100 toward the square slot 1, and the inclination angles of the two guiding surfaces are different, which can be adjusted by those skilled in the art according to practical requirements.

The connection of the transverse groove 21 and the longitudinal groove 22 forms a small square groove, and the square groove is positioned in the square groove 1, so that the connection of the square groove 1, the longitudinal groove 22 and the transverse groove 21 has an intersection.

The square groove 1 is square in cross section and is used for being matched with a square screwdriver head or a square screwdriver head, so that a driving effect is achieved.

A limiting block 11 is arranged on the square groove 1. The arrangement of the limiting block 11 is matched with a screwdriver bit or a screwdriver bit of the driving square groove 1 to form a limiting driving effect. In this embodiment, the number of the limiting blocks 11 is four, and the limiting blocks 11 are located on the bottom surface of each corner of the square groove 1.

The positioning groove 3 is positioned below the square groove 1, and the positioning groove 3 is communicated with the square groove 1. Through setting up of constant head tank 3, form the fixed effect of location, ensure concentricity, improve the driving effect. The positioning groove 3 is specifically in an inverted cone shape, so that the positioning effect is improved.

Compared with the prior art, if the cross groove 2 is overlapped with the square groove 1, the cross groove 2 is easy to abrade the joint of the cross groove 2 and the square groove 1 in the matching process of a screwdriver bit or a screwdriver bit in the driving process because the size of the cross groove 2 is limited, and the cross groove 2 cannot be continuously used because of slipping after multiple use. By adopting the structure, the size of the transverse groove 21 is increased, so that the contact area between the screwdriver bit or screwdriver bit and the cross groove 2 in the matching process is larger, and the structure similar to two halves is formed through the transverse groove 21, so that the head 100 forms a certain elastic effect, a certain twisting effect is formed in the rotation driving process, and buffering is formed, so that the cross groove 2 is not easy to wear, and the service life is prolonged.
