New Description: [New Technology Field] This creation department is about a lock expansion type expansion bolt, especially one that cuts a number of grooves at one end of a piece, and then winds a gap to make a The sleeve is designed to reduce the manufacturing cost, and at the same time, in addition to being more labor-saving in implementation, it is also an innovative design of a lock-expansion expansion bolt that increases the gripping force. [Prior Art] Press, general lock expansion expansion bolt, please refer to the first and second figures, the first picture is the exploded view of the existing lock expansion expansion bolt, the second picture is the side of the existing lock expansion expansion bolt The cross-sectional view mainly includes a bolt (91), a sleeve (92), a washer set (93) and a nut (94), wherein the bolt (91) is a rod body, and one end thereof is formed as An enlarged conical head (911), and the other end is provided with a threaded section (912) of a suitable length, and the sleeve (92) is provided with a plurality of grooves (921) at the end of the orifice of the sleeve, so that the tube The mouth edge forms a plurality of pressing pieces (922), and the sleeve (92) and the washer set (93) are sleeved on the outer edge of the bolt (91), and the nut (94) is screwed to one end of the bolt (91). Threaded section (912). In order to fix the object on the wall or the ground, the hole can be drilled in the predetermined position, then the expansion expansion bolt is placed in the hole, and the screw s (94) is rotated to make the bolt (91) The conical head (911) at one end urges the abutting piece (922) of the sleeve (92) to expand outwardly and abut against the inner wall of the circular hole, thereby forming the lock expansion expansion bolt on the inner wall of the circular hole to form a fixer. . However, the above-mentioned prior art structure has been found to have the following disadvantages when it is actually used, and it is urgent to be improved. 5 M313188 ι. The sleeve of the existing structure has a groove formed at one end of the nozzle but is sleeved. The outer periphery of the other end of the cylinder is closed, so that the end of the sleeve is not easily expanded. Therefore, when the nut of the bolt is forced to abut against the sleeve of the sleeve, the sleeve is forced against the piece. It is less difficult to expand outwards, so rotating the nut will be more labor-intensive. 2. Since the sleeve of the existing structure is manufactured in one piece, it is firstly manufactured into a long cylinder, and then the long cylinder is cut into a sleeve of an appropriate length, and then the groove is formed one by one at one end of the sleeve. Therefore, the manufacturing process is rather cumbersome and the manufacturing cost is also quite high. The reason is that the creators, in view of this, adhere to the actual design and manufacturing experience of relevant industries for many years, and research and reform the existing structure and lack, and provide an innovative lock-expansion expansion bolt, in order to completely improve all the existing missing. [New content] This creation department is about a lock expansion type expansion bolt, which is mainly used on a bolt, sequentially wearing a sleeve, a washer set, and then screwing a nut. The bolt is a rod. The body has a --shaped end formed as an enlarged conical head, and the other end is provided with a threaded section, and the sleeve is firstly punched into a plurality of grooves at one end of the piece, and then wound to leave a slit. And by using the groove to form a plurality of pressing pieces at the edge of the nozzle at one end of the sleeve, t (4), the locking cone of the locking type of the bolt is placed in the round hole of the wall, and is borrowed Bolt the threaded section of the screw nut to push the washer set in sequence to push the cylinder, so that the sleeve of the sleeve is expanded outward by the bolt-end enlarged cone head to the top deck card f According to the design, since the sleeve is formed by body-molding and then punching a plurality of grooves and then winding, the manufacturing cost can be reduced, and at the same time, when used, (4) sleeve In the winding M313188, the day inch, leaving a gap along the axis of the outer circumference, can make the sleeve more forceful Expansion, to serve up more effort and increase its efficiency by the bond strength of. [Embodiment] In order to make the technical means and achievement of the creation of this creation easy to understand, the following diagrams are included: » One "The first creation is about a lock expansion expansion bolt, please refer to I, IV, As shown in the figure, the third figure is a three-dimensional view of the creation lock expansion expansion bolt. The fourth figure is a side cross-sectional view of the creation lock expansion expansion bolt. ^The system includes a bolt (1) and a sleeve. (2) a washer set (3) and a nut (4), wherein the bolt 〇 is a rod body, one end of which is formed as an enlarged conical head (11), and the other end is provided with a a threaded section (12) of a suitable length, the sleeve (2) is formed by punching a plurality of grooves (22) at one end of the integrally formed sheet, and then winding a slit (21), and borrowing the groove The groove (22) forms a plurality of pressing pieces (23) at the edge of the sleeve end of the sleeve (2), and sequentially sleeves the sleeve (2) and the washer group (3) on the outer edge of the bolt (丨) So that the pressing piece (23) of the sleeve (2) is placed on the periphery of the conical head (11) of the bolt (丨), and then the nut (4) is screwed to the threaded section of the bolt (1) (10) According to this, the nut (4) is screwed in and pushed by the washer group (3) and the sleeve (2) in order, so that the sleeve (10) is forced by the bolt (1)-end enlarged conical head Part (1)) is broadcasted outwards. When the field is used, please refer to the fifth figure, which is a schematic diagram of the implementation of the lock expansion type expansion bolt. Firstly, the hole (9) of the predetermined depth is drilled on the wall (5), and the lock expansion expansion bolt is inserted. The front end of the bolt (1) _ head (1) is built into the round hole (9), and then the nut (4) is screwed in the direction of the round hole (51), so that the nut (4) can be screwed in while the washer group (3) is inward M313188 Forcing 2 ((L)) and: the conical head (1) of the bolt (1) is forced against the sleeve (2) along its circumference: two = sleeve (2) is externally forced during winding forming = lock: ===== By doing this with the structure and implementation of the creation of the ί 点 可 ' ' 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本When the piece is pressed, the sleeve expands and abuts against the inner wall of the round hole, so the nut 2. The outer circumference of the nut is a gap, so the degree of the sleeve is forced to be larger, so that the forced piece is more It is easy to resist and jam the inner wall of the member hole of the wall soil. Therefore, the force between the lock expansion type expansion bolt and the wall will be better. < 3. The sleeve of the present invention is manufactured by re-winding a plurality of grooves in the body-formed body, so that the manufacture of the spine is relatively simple and the manufacturing cost is relatively low. The above-mentioned embodiment of the creation can indeed achieve the expected use of the power of the government's specific structure, not only has not been seen in similar products, ^ has been disclosed before the application, Cheng has fully complied with the provisions of the Patent Law With the request, the friend proposes a new type of patent according to law, please ask for the review, and give the special brake, then it is really sensible.
