Detailed Description

In order to facilitate understanding of the invention, the invention will be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the invention are shown, but which can be embodied in many different forms and are not limited to the embodiments described herein, but which are provided so as to render the disclosure of the invention more thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present; when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; the terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; as used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example 1

Referring to fig. 1, 2 and 3, the bolt socket for vehicles of this embodiment includes a socket body 100 and a hexagon bolt 200, the socket body 100 includes a pressing surface 110 attached to a workpiece 300 and a fixing surface 120 for mounting the bolt, the fixing surface 120 is provided with a circular boss 130, the circular boss 130 is internally provided with a hexagonal groove 140, the center of the hexagonal groove 140 is provided with a circular through hole 141, the pressing surface 110 is an outwardly convex circular arc surface 111, the upper end and the lower end of the socket body 100 are both provided with outwardly convex clamping platforms 150, the clamping platforms 150 are symmetrical with respect to a central axis surface a of the socket body 100, if the bolt socket of the present design is not used, the hexagon bolt 200 is directly used for connection, since the vehicle often vibrates during driving, or the mutual movement between the workpieces 300 can cause the bolt head of the hexagon bolt 200 to rotate relatively with the nut, the connection between the workpieces 300 is loosened, further causing hazards such as traffic accidents, and the bolt clamping seat of the design is used, the clamping seat body 100 is clamped with the workpiece 300, the hexagonal groove 140 is used for fixing the bolt head of the hexagonal bolt 200, after long-time use, the bolt head is fixed by the hexagonal groove 140 and does not rotate relative to the nut, and the workpiece 300 is firmly and stably connected.

The distance between the highest point and the lowest point of the arc surface 111 of the embodiment is smaller than 1mm, if the distance between the highest point and the lowest point of the arc surface 111 is too large, that is, the arc surface 111 is convex, the contact position between the arc surface 111 and the workpiece 300 is smaller, the suspension state on both sides of the contact surface is too much, and the connection between the cassette body 100 and the workpiece 300 is easy to shake, so the distance between the highest point and the lowest point of the arc surface 111 should be smaller, but when the distance is too small, the arc surface 111 approaches to a plane, the acting force of the hexagon bolt 200 on the cassette body 100 is smaller along the moment of the cassette table 150, so that the cassette table 150 cannot be slightly deformed to clamp the workpiece 300, and the effect is not good, therefore, the distance between the highest point and the lowest point of the arc surface 111 is limited to 1mm, that the connection stability is satisfied, and the cassette.

The inner sides of the clamping platforms 150 of the embodiment are all provided with the tooth surfaces 151, the tooth space of the tooth surfaces 151 is 1mm, if the tooth space is too large, the density of teeth is small, the friction force with the workpiece 300 is small, the clamping stability of the workpiece 300 and the clamping seat body 100 is not high, if the tooth space is too small, the teeth are dense, the contact surfaces of the teeth and the workpiece 300 are similar to plane contact, the friction force is small, and the clamping stability of the workpiece 300 and the clamping seat body 100 is not high, so the tooth space of the tooth surfaces 151 is set to be 1mm, and the friction force between the clamping platforms 150 and the workpiece 300 is maximum.

The degree of depth of hexagonal groove 140 of this embodiment is greater than half of hexagonal bolt 200 first thickness, because in-service use, the inner wall of hexagonal groove 140 can not laminate completely with hexagonal bolt 200's lateral wall, there is the gap, consequently, hexagonal bolt 200's bolt head can take place slightly to rock in use, further the connection that leads to the nut is the optimum position not, the firmness of connection is not enough, consequently, establish the degree of depth with hexagonal groove 140 into being greater than half of hexagonal bolt 200 first thickness, make hexagonal bolt 200 not take place to rock when using or rock the very little firmness that does not influence the installation.

The diameter of the circular through hole 141 of the embodiment is slightly larger than the diameter of the screw of the hexagon bolt 200, and the design enables the installation of the hexagon bolt 200 to be convenient and fast.

The bolt head lateral surface of hexagon bolt 200 of this embodiment and the laminating of the inner wall of hexagon groove 140, the bolt head of fixed hexagon bolt 200 that this design made hexagon groove 140 can be stable avoids hexagon bolt 200 to take place to rotate.

In the embodiment, an included angle between a connecting line of each tooth height point of the tooth surface 151 and the extrusion surface 110 is 89 °, if the included angle is 90 °, that is, the clamping surface of the clamping table 150 is perpendicular to the extrusion surface 110, when the clamping device is used, the clamping table 150 has almost no acting force on the workpiece 300, the clamping effect is poor, and the included angle is 89 °, the clamping table 150 is slightly deformed under the stress action, the workpiece 300 is tightly clamped, and the clamping effect is good.

The above-mentioned embodiments only express a certain implementation manner of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention; it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention; therefore, the protection scope of the present invention should be subject to the appended claims.
