Description

  The present invention relates to a lifting / lowering positioning structure for a nail plate of a roll nailer.

  The nail used in the roll nailer is installed in a roll nail base, and when a nail base in which one roll nail is installed in a normal roll nail base is actually used, roll nails of different lengths are used. As it appears, the traditional approach renovates the nail base into a structure that can be adjusted for elevation.

  FIG. 1 shows a conventional structure of the above-described nail base lifting adjustment and positioning structure. A space 12 that extends horizontally is arranged mainly in the central column 11 of the nail winder 10, and a positioning slot hole 13 that is spaced vertically is provided in the space to be removed, and a positioning button 20 that operates horizontally is provided. A control end 21 that is disposed and protrudes into a through hole 32 provided corresponding to the central convex tube 31 of one nail plate 30 is provided, and a clamping edge for fixing the positioning slot hole 13 in the middle of the positioning button 20 is provided. 22, an axle bolt 23 to be inserted into the other axial hole 33 of the central convex tube 31 is installed on one side of the positioning button 20, and the positioning button 20 is placed on the outside of the axle bolt 23 by a single spring 24. The nail plate is in a positioning state by constantly replacing the pinching edge 22 in the direction of the positioning slot hole 13. When adjusting the height of the nail pan 30 having the preceding structure, as shown in FIG. 2, when the control end 21 of the positioning button 20 is pushed inward to release the pinching edge 22 from the positioning slot hole 13, Is released and achieve the purpose of lifting adjustment. However, when this conventional structure is actually used, the following problems exist.

  1. In order to assemble the positioning button 20, the volume of the central column 11 of the nail winder 10 needs to be considerably large and to form a laterally penetrating space 12 that has pierced the contents. Since the thickness becomes thinner and the structural strength of the central pillar 11 becomes weaker, the durability and durability become problems.

  2. Since the control end 21 of the positioning button 20 is not long enough to be hit against the roll nail mounted therein, the pressing end of the positioning button 20 cannot be pushed unless force is applied. Instead, it becomes inconvenient.

  Therefore, the above conventional nail plate lifting positioning adjustment structure is obviously not perfect in terms of structural strength and operational convenience, and it is the efforts of related companies to research and develop the latest design that is more ideal and practical. I am thinking and waiting to break through.

  Taking this point into consideration, the inventor made a suitable design against the above goals based on years of manufacturing and development of related products and design experience, and after careful evaluation, Completed the invention.

  An object of the present invention is to provide an elevating and positioning structure for a nail plate of a roll nailer.

  In order to achieve the above object, the elevation positioning structure of the present invention has the following features. A plurality of positioning slots are provided at intervals on the side wall of the central column of the roll nail base, the positioning member (positioning ball) is movably installed in the through hole of the positioning member, and the brake pipe is loosened. Slide in the axial direction outside the tube in the vertical direction of the nail base in the state. A resistance portion is provided on the inner wall of the brake pipe, and when the brake pipe comes to the bottom dead center, the position is opposed to the through hole of the positioning member, and the positioning member is pushed inward. Further, the top end portion of the upper elastic body is locked by a stopper provided on the tube in the axial direction, and the bottom portion is stopped by the resistance portion of the brake tube, so that the brake tube is always pushed downward.

  The center column only needs to have a positioning slot space for half of the positioning member (positioning ball) on the side wall, so the influence on the structural strength of the center column is minimized, so the center column is stronger and more durable. Have sex.

  This can be achieved by simply pulling and pulling the brake pipe in the axial direction when performing the lifting / lowering adjustment work of the nail base, and thus has a practical effect of convenient operability and a durable structure.

  Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  3-5 is a figure which shows the suitable Example in the raising / lowering positioning structure of the nail plate of the roll nailer of this invention. As shown in FIGS. 3 to 5, the central column 41 of the roll nail base 40 of the roll nailing machine A and the tube 51 in the vertical direction of the nail base 50 are provided at opposite positions, and the vertical position of the nail base 50 is set. The tube 51 in the direction moves in a relaxed state along the central column 41 outside the central column 41 in the axial direction, and a snap ring 412 is disposed at the top end of the central column 41. The elevation positioning structure is configured as follows.

  The plurality of positioning slots 42 are provided on both side walls facing the central column 41 of the roll nail base 40 with a space in the vertical direction.

  The through holes 52 of the two positioning members are provided at predetermined positions on the tube walls on both sides facing the tube 51 in the longitudinal direction of the nail base 50 and penetrate the tube wall in the radial direction.

  As for the positioning member, in this embodiment, two positioning balls 60 are employed and arranged in the through hole 52 of the positioning member in a movable state.

  The brake pipe 70 slides in the axial direction outside the tube 51 in the longitudinal direction of the nail base 50 in a relaxed state, and a resistance portion 71 is provided on the inner wall of the brake pipe 70 (in this embodiment). The resistance portion is in the form of a ring-shaped flange), and when the brake pipe 70 comes to the bottom dead center position, the resistance portion becomes the position opposite to the through hole 52 of the positioning member of the tube 51 of the nail base 50. Then, the positioning ball 60 is pushed inward.

  The upper elastic body 81 employs a spring in this embodiment, and is provided between the top end portion of the inner wall of the brake pipe 70 and the top end portion of the tube 51 in the vertical direction of the nail base 50. The top end portion of the upper elastic body 81 is locked by a stopper 53 provided on the tube 51 in the vertical direction, and the bottom portion of the upper elastic body 81 is stopped at the top end portion of the resistance portion 71 of the brake pipe 70, so that it always moves downward. Place the brake pipe 70 at the bottom dead center position.

  The lower elastic body 82 employs a spring in this embodiment, and is provided between the bottom end of the resistance portion 71 of the braking pipe 70 and the nail base 50. The elastic body pushes the braking pipe 70 upward by elasticity, and the upper elastic body 82 Since a balance effect that cancels the elasticity of 81 is obtained, the brake pipe 70 is maintained in a predetermined position.

  The stopper 53 provided at the top end portion of the tube 51 can employ a snap ring.

  Further, the top end portion of the brake pipe 70 can be sealed by the cover 72.

  The design is assembled by the above structure, and the operation status of the present invention will be described as follows.

  FIG. 6 is a view showing a state in which the nail base 50 is positioned at the lowest position. In this state, the nail base 50 can be mounted with a longer roll nail B1. At this time, the brake pipe 70 is pushed downward by the upper elastic body 81 to a predetermined bottom dead center position, so that the resistance portion 71 is connected to the through hole 52 of the positioning member of the tube 51 of the nail base 50. At the opposing position, the positioning ball 60 is pushed inward and fixed in the positioning slot 42 of the central pillar 41 of the nail base 40, whereby the nail base 50 is in a positioning state.

  As shown in FIG. 7, when the nail base 50 is adjusted, the user directly pulls the brake pipe 70 upward, so that the resistance portion 71 simultaneously moves upward, so that the clogging state of the positioning ball 60 is released. Then, the positioning state of the nail base 50 is released.

  As shown in FIG. 8, the top end portion of the upper elastic body 81 is locked by a stopper 53 provided on the tube 51, and the bottom portion of the upper elastic body 81 is stopped by the top end portion of the resistance portion 71 of the brake pipe 70. When the user continuously pulls the brake pipe 70 upward, the tube 51 and the nail base 50 in the vertical direction rise, and at the same time, the upper elastic body 81 is compressed, so that elasticity is accumulated and the positioning ball is accumulated. When 60 reaches the other positioning slot 42, the brake pipe 70 is released, and the brake pipe 70 receives the elastic release action of the upper elastic body 81 and quickly returns to the downward direction. As a result, the resistance portion 71 also returns to the position facing the through hole 52 of the positioning member, the positioning ball 60 is pushed inward, and is fixed to the positioning slot 42 of the central column 41 of the nail base 40, and the nail base 50 is In another positioning state. In this state, the roll nail B2 having a shorter length can be placed on the nail base 50.

  In the state shown in FIG. 8, when the user wants to adjust the nail base 50 downward, similarly, if the brake pipe 70 is pulled upward, the clogging state of the positioning ball 60 is released, and the positioning state of the nail base 50 is also changed. Released. However, at this time, when the user pushes down the nail base downward with one hand to the next height position and then releases the brake pipe 70, the positioning effect is obtained again.

  11 and 12 are views showing another preferred embodiment of the elevation positioning structure of the present invention. The main difference from the above embodiment is the locking method of the tube 51B in the vertical direction, and the top end portion of the central column 41B passes through the cover 72B and then the top end portion of the central column 41B is the same. The two pin columns 43 are penetrated, and both ends of the pin columns are projecting, thereby locking the upper movement of the tubes 51B, the cover 72B, and the brake pipe 70B in the vertical direction. Another feature of this embodiment is that there is an inner protruding edge 73 on the outside of the brake pipe 70B, and there is an advantage that it does not slip more stably when gripping with a hand and applying force.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this embodiment, and all modifications to the present invention are within the scope of the present invention unless departing from the spirit of the present invention.
