Description

一种用于钻头连接的套筒技术领域[0001] 本发明涉及一种套筒,具体是一种用于钻头连接的套筒。 A telescopic drill bit for connection Technical Field [0001] The present invention relates to a sleeve, particularly a sleeve for connecting a drill bit. 背景技术[0002] 随着钻孔作业的不断发展,钻头作为一种钻孔工具被运用得越来越多。 [0002] With the continuous development drilling operations, the drill as a drilling tool is using more and more. 通常是将钻头和旋杆通过焊接等方式固定连接,以使钻头具有较强的稳定性。 The bit is usually fixed and the swivel lever are connected by welding or the like, so that the drill bit has a strong stability. 但是,旋杆的长度往往是固定的,而有时我们需要一个合适的旋杆长度与钻头配合进行钻孔作业,这样就造成了一些不便。 However, the length of the rotating rod is often fixed, but sometimes we need a proper spin rod length and drill with drilling operations, thus causing some inconvenience. 还有,当钻头或者旋杆发生损毁后,只能将钻头和旋杆整体更换,这样不但实用性不高,同时还造成了资源的浪费。 Also, when the rotating rod drill or damage occurs, and only the drill bit rotating rod to replace the whole, this is not only practicality is not high, but also resulted in a waste of resources. 发明内容[0003] 本发明所要解决的技术问题是,提供了结构简单、长度可调、方便更换的一种用于钻头连接的套筒。 [0003] The present invention solves the technical problem is to provide a simple structure, adjustable in length, to facilitate replacement of a drill sleeve for connection. [0004] 本发明为解决技术问题主要通过以下技术方案实现:一种用于钻头连接的套筒, 包括套筒本体,所述套筒本体上、下部分别为内接筒与外接筒,内接筒与外接筒连为一体, 内接筒的外径与外接筒的内径相等,内接筒上设有外螺纹,外接筒上设有与外螺纹相配合的内螺纹。 [0004] The present invention is to solve the technical problem is mainly achieved by the following technical solution: A connection sleeve for a drill bit, comprising a sleeve body, the sleeve body, an external cylinder and a lower portion respectively connected to the inner cylinder, inscribed cylindrical external cylinder is integral with, an inner diameter equal to the outer diameter of the external cylinder inscribed cylinder, provided with an external thread inscribed cylinder, provided with an internal thread cooperating with the external thread on the external cylinder. 内接筒用于固定转轴,外接筒用于内接钻头,两个套筒之间可通过内接筒和外接筒相互相连,增加套筒的长度。 Inscribed cylinder for fixing the rotary shaft, an external tube connected to the drill bit can be connected to each other through the inner tube and the external contact between the two cylindrical sleeves, increasing the length of the sleeve. [0005] 所述外接筒与内接筒的中心线相互重合。 The [0005] external cylinder inscribed cylinder center line coincide with each other. [0006] 所述外接筒的长度等于或大于内接筒的长度。 [0006] The external cylinder length equal to or greater than the length of the crimp barrel. [0007] 本发明与现有技术相比具有以下优点和有益效果:(I)本发明替代了原来的旋杆,采用了外接筒和内接筒的组合方式,钻头内接于外接筒,可以使钻头的拆卸很方便。 [0007] The present invention as compared with the prior art has the following advantages and beneficial effects: (I) of the present invention to replace the original rotating rod, using a combination external cylinder and the inner cylinder is connected, an external tube connected to the drill bit, can be so remove the drill bit is very convenient. [0008] (2)本发明之间可以相互连接,使得整个套筒处于可调状态,可很好地满足钻孔的要求。 [0008] (2) of the present invention may be connected to each other, so that the entire sleeve is adjustable state, can satisfy the requirements of the borehole. [0009] (3)本发明结构简单,实用性强。 [0009] (3) the structure of the present invention is simple and practical. 附图说明[0010] 图I为本发明的主视图;图2为本发明的俯视图;图3为本发明的剖面图。 BRIEF DESCRIPTION [0010] Figure I a front view of the present invention; FIG. 2 is a plan view of the invention; FIG. 3 is a sectional view of the invention. [0011] 附图中所对应的附图标记为:1、外接筒,2、内接筒,3、外螺纹,4、内螺纹。 [0011] In the drawings corresponding reference numerals: 1, an external cylinder 2, the inscribed cylinder, 3, external thread 4 and internal thread. 具体实施方式[0012] 下面结合实施例对本发明作进一步的详细说明,但本发明的实施方式不限于此。 DETAILED DESCRIPTION [0012] The following embodiments in conjunction with embodiments of the present invention will be further described in detail, but the embodiment of the present invention is not limited thereto. [0013] 实施例:如图I、图2及图3所示,本发明包括套筒本体,所述套筒本体上、下部分别为内接筒2 与外接筒1,内接筒2用于固定转轴,外接筒I用于内接钻头;内接筒2与外接筒I连为一体,内接筒2的外径与外接筒I的内径相等,外接筒I与内接筒2的中心线相互重合;内接筒2上设有外螺纹3,外接筒I上设有与外螺纹3相配合的内螺纹4,两个套筒之间可通过内接筒和外接筒相互相连,增加套筒的长度;外接筒I的长度等于或大于内接筒2的长度。 [0013] Example: in FIG.
