Description

Field of the Invention

The present invention relates to an improved structure of an anchor dowel tool, more particularly to a tool which is an anchor dowel tool used to extract an anchor pin in order to deploy and fix the dowel in a Wall.

Context of the Invention

There are two common types of anchors available on the market. One of them is an insertion anchor anchor, and the other is an extractable anchor anchor; the insertion type anchor pin is inserted into a pre-drilled hole, and the lateral edge of the anchor pin is expanded to abut against the inner wall of the hole; the extractable anchor pin is equipped with a rod which can be pulled out by a tool while the pin is held outwardly axially, so that the lateral edge of the pin is anchoring is widened to abut against the inner wall of the hole. An anchor anchor tool is a special tool dedicated to extractable anchor anchors and is able to attach the extractable anchor anchor effectively, easily and quickly.

British Patent No. GB2224230A and the Patent of the Republic of China No. 390253 relate to a structure of a tool for anchors, with which, once an ankle is inserted into the hole, the anchor anchor tool pulls on the stem thereof axially outwardly, so that the lateral edge of the peg is expanded to abut against the inner wall of the hole to quickly fix the anchor pin.

The pin of the anchor pin tool according to the above-mentioned patents, however, has no graded display function, and the hollow wall anchor pin is concealed in the other end of the wall, so that users can not easily see the anchor pin and do not know the pulling force or the degree of deployment. If the stem of the hollow wall anchor is too loose, the deployment will be insufficient and the effect of the hollow wall anchor can not be maximized. If the stem of the hollow wall anchor pin is pulled too far, the hollow wall anchor pin may be easily damaged when it is too wide. Clearly, the conventional anchor pin poses usage problems and requires additional improvements. SUMMARY OF THE INVENTION The primary object of the present invention is to provide an improved structure of an anchor dowel tool for efficiently and quickly allowing users to visually inspect the pulling length of an anchor plug. , so as to maximize the fixing effect and also the duration of use of the anchor pin.

Description of Preferred Embodiments

Figures 1 to 5 show an improved structure of an anchor pin tool according to the present invention, which comprises: a gun-shaped body 10, having a base 11 placed at the top of the gun-shaped body 10; the base 11 has a fixed handle 12 placed at the lower end of the base, an end wall 111 placed at one end of the fixed handle 12, a stop device 13 fixed on one end of the base 11 other than the end wall 111; the interior of the base 11 has a front separation plate 112 and a rear separation plate 113, a front chamber 114 formed between the front separation plate 112 and the stop device 13, a rear chamber 115 formed between the rear partition plate 113 and end wall 111, and an intermediate chamber 116 formed between the front and rear chambers 114, 115; a plurality of locating bolts 14 are engaged through the rear chamber 115 and the intermediate chamber 116 pivotally; the front chamber 114 has a sliding seat 15 arranged in it; the sliding seat 15 has a groove 151 substantially V-shaped formed on one side of the sliding seat 15 and close to the stop device 13, adapted to integrate a rod (not shown in the figure) of an anchor pin so to facilitate traction on the anchor pin; the sliding seat 15 has an integrated groove 152 formed on one side of the sliding seat 15 other than the side having the groove 151; a mobile subassembly 20, constituted by a movable handle 21 pivotally connected to the base 11, in a predetermined position, by a turntable 22 having a through hole 221, and a first spring 23; the top of the turntable 22 extends to the rear chamber 115 and abuts a locating bolt 14, and the lower portion of the turntable 22 abuts the movable handle 21; the two ends of the first spring 23 are in abutment against the turntable 22 and against the end wall 111 of the base 11 respectively; a stop and release subassembly 30 constituted by a stop plate 31 and a second spring 32; the abutment plate 31 has a through hole 311, and the top of the abutment plate 31 extends into the intermediate chamber 116 and abuts against the positioning bolt 14; the lower part of the abutment plate 31 extends outside the base 11, and the two ends of the second spring 32 compress the abutment plate 31 and the rear separation plate 113 respectively; a median rod 40, having an indicator portion 41 placed at the outer periphery of one end of the middle rod 40, an integrated groove 42 formed at the outer periphery of one end of the middle rod 40 other than the end having the indicator part 41; one end of the middle rod 40 having the integral groove 42 passes through the end wall 111, the first spring 23, the through hole 221 of the turn-up plate 22, the rear partition plate 113, the second spring 32, the through hole 311 of the abutment plate 31, the front separation plate 112 and a restoring spring 50 placed between the sliding seat 15 and the front separation plate 112; the integrated groove 42 of the middle rod 40 is integrated in the integrated groove 152 of the sliding seat 15, so that the middle rod 40 is connected to the sliding seat 15.

The middle rod 40 has a cross section of circular or oval shape.

The middle rod 40 may have a cross section of polygonal shape.

The indicator portion 41 of the middle rod 40 is a graduation.

The indicator portion 41 of the middle rod 40 may be a label of different colors.

Referring to FIGS. 1-5 again, it will be understood that when a user uses the anchor pin tool of the present invention with the above-mentioned assembly to pull on an anchor pin (not shown on FIG. the figures), the stop plate 31 is stopped by the second spring 32 and the positioning bolt 14 and is slightly inclined, so that the top and the lower part of the through hole 311 adjoin the top and the lower part of the rod median 40 for clamping and securing the center rod 40. Then, the movable handle 21 is actuated to pivot and rotate the turntable 22, so that the top and bottom of the through hole 221 adjoin the top and the lower part of the middle rod 40 to tighten the middle rod 40 and move the middle rod 40 towards the end wall 111. When the turning plate 22 is released, the side wall e of the through hole 221 is separated from the edge of the middle rod 40. In other words, the abutment plate 31 limits the middle rod 40, so that the central rod 40 is stopped and is immobilized, and that it will not resume its original position by the action of the restoring spring 50. When the movable handle 21 is repeatedly actuated repeatedly, the sliding seat 15 is caused to move gradually to pull on the anchor pin.

Once the periphery of the anchor pin is progressively enlarged and positioned stably in the hole, the pin of the anchor pin is removed from the sliding seat 15, and the stop plate 31 is actuated; the through-hole 311 is rotated accordingly, so that the side walls of the top and the bottom of the through-hole 311 are separated from the top and bottom of the middle rod 40. Because the middle rod 40 is not limited by the stop plate 31, the resilience of the restoring spring 50 moves the middle rod 40 in an opposite direction to connect and return the slide seat 15 to its original position. The overall operation of the tool according to the invention is simple and practical.

It should be noted that the median rod 40 has a graduation or an indicator portion 41 with a label of different colors placed at the outer periphery of one end of the middle rod 40. When the middle rod 40 is not extracted, the the indicator part of the middle rod 40 is not exposed to the outside, but is hidden inside the base 11. When a user pulls the middle rod 40 outwards, the indicator portion 41 of the middle stem 40 will appear slowly (as shown in Figures 2 and 5). In this preferred embodiment, the indicator portion 41 is a scale, and the user can visually inspect and easily adjust the graduation to pull the anchor pin to a degree required to handle a different sized anchor pin, so to obtain the best use effect, to avoid the problem caused by excessive or insufficient traction of the anchor anchor, and to improve the fixing effect and the duration of use of the anchor anchor.

To summarize the above description, the improved structure of an anchor plug tool according to the present invention overcomes the disadvantages of the conventional structure of the anchor pin tool; the present invention satisfies the requirements for a patent application, and is therefore duly registered in a patent application.
