Description
技术领域 technical field
本实用新型涉及一种方便拧入的螺杆。 The utility model relates to a screw rod which is convenient to be screwed in.
背景技术 Background technique
螺栓为日常生活和工业中常用的一种紧固件，现常用的标准公制螺栓，在锁入时容易划伤定位螺杆的螺纹，导致装配残余扭力过高，在装配时采用预拧入工序，然后再用工具锁紧，费时费力。 Bolts are a kind of fasteners commonly used in daily life and industry. The standard metric bolts commonly used now are easy to scratch the thread of the positioning screw when locking in, resulting in excessive residual torque in assembly. The pre-screwed process is used during assembly. Then use a tool to lock it, which is time-consuming and labor-intensive.
实用新型内容 Utility model content
鉴于背景技术存在的不足，本实用新型所要解决的技术问题是提供一种结构简单、导向效果好、装配效率高且不损伤螺纹的方便拧入的螺杆。 In view of the deficiencies in the background technology, the technical problem to be solved by the utility model is to provide a convenient screw-in screw with simple structure, good guiding effect, high assembly efficiency and no damage to the thread.
本实用新型是采取如下技术方案来完成的：方便拧入的螺杆，其螺杆包括定位部和导向部，其特征是：所述导向部包括倒角导向部和圆形导向螺纹，所述圆形导向螺纹设于倒角导向部和定位部之间，所述圆形导向螺纹的螺纹牙外轮廓为圆弧形，所述圆形导向螺纹的螺纹牙牙高为定位螺杆牙高的一半。 The utility model is completed by adopting the following technical scheme: a screw rod that is convenient to be screwed in, and the screw rod includes a positioning part and a guide part, and the feature is that the guide part includes a chamfered guide part and a circular guide screw thread, and the circular guide part The guide thread is arranged between the chamfered guide part and the positioning part, the thread outer contour of the circular guide thread is arc-shaped, and the thread height of the circular guide thread is half of the tooth height of the positioning screw.
本实用新型中的方便拧入的螺杆，结构简单，导向效果好，在利用通用装配工具自动装配中，倒角导向螺纹将螺栓导入螺纹孔内，圆形导向螺纹使后面的定位螺杆顺利进去螺纹孔中，并且不损伤定位螺杆上的螺纹，省时省力、装配效率高。 The conveniently screwed-in screw in the utility model has simple structure and good guiding effect. In the automatic assembly using a general assembly tool, the chamfered guide thread guides the bolt into the threaded hole, and the circular guide thread allows the positioning screw behind to enter the thread smoothly. In the hole, without damaging the thread on the positioning screw, it saves time and effort, and the assembly efficiency is high.

具体实施方式 detailed description
附图表示了本实用新型的技术方案及其实施例，下面再结合附图进一步描述其实施例的各有关细节及其工作原理。 The accompanying drawings show the technical solution of the utility model and its embodiments, and the details and working principles of the embodiments will be further described below in conjunction with the accompanying drawings.
参照图1、图2所示，本实用新型提供的一种方便拧入的螺杆，包括定位部1和导向部2，定位部1上设置普通螺纹，所述导向部2包括倒角导向部3和圆形导向螺纹4，倒角导向部3实际为斜面倒角，所述圆形导向螺纹4设于倒角导向部3和定位部1之间，所述圆形导向螺纹4的螺纹牙外轮廓为圆弧形，所述圆形导向螺纹4的圈数为2-3圈，所述圆形导向螺纹4的螺纹牙牙高为定位部1牙高的一半，所述圆形导向螺纹4的螺距与定向部1螺距相同。 With reference to Fig. 1, shown in Fig. 2, a kind of screw rod that is conveniently screwed in provided by the utility model comprises positioning part 1 and guide part 2, and common screw thread is arranged on the positioning part 1, and described guide part 2 comprises chamfered guide part 3 and the circular guide thread 4, the chamfering guide part 3 is actually a bevel chamfer, the circular guide thread 4 is arranged between the chamfering guide part 3 and the positioning part 1, and the outer thread of the circular guide thread 4 The contour is arc-shaped, the number of turns of the circular guide thread 4 is 2-3 turns, the thread height of the circular guide thread 4 is half of the tooth height of the positioning part 1, and the height of the circular guide thread 4 is half of that of the positioning part 1. The pitch is the same as that of the orientation part 1.
在利用通用装配工具自动装配中，倒角导向部3将螺杆导入螺母孔内，接着圆形导向螺纹4将定位部杆1外螺纹导入螺母的内螺纹牙，使定位螺杆1螺纹顺利进入螺母。 In the automatic assembly using a general assembly tool, the chamfered guide part 3 guides the screw into the nut hole, and then the circular guide thread 4 guides the external thread of the positioning part rod 1 into the internal thread of the nut, so that the positioning screw 1 thread enters the nut smoothly.
