Description

Technical Field

[0001] The utility model relates to the technical field of punching tools, in particular to a punching tool for installing hinges. Background Art

[0002] Invisible hinges and hinges are important hardware that connect window frames and window sashes to open and close the window sashes. In the early days, many families chose hinges as hinges to connect window sashes due to the high price and lack of technical maturity of hinges. However, as hinge technology became more mature and stable, people were willing to replace the hinges installed on the original windows with hinges because of the functionality of hinges. However, when installing hinges, it is necessary to punch holes in the profiles in advance. The windows originally equipped with hinges do not have holes reserved for the hinges to pass through. Therefore, when replacing hinges with hinges, it is necessary to punch holes in the window sashes that have been assembled into finished products. At present, the existing punching method is to open the profile with a saw blade or a flat shovel. This method is complicated to operate and has low precision. It may damage the profile, causing the profile to crack and lead to water leakage. Summary of the invention

[0003] The utility model provides a punching tool for installing hinges, which is easy to operate and has high precision. The specific technical solution is as follows:

[0004] A punching tool for installing a hinge, comprising a holding handle and a pressing handle connected by a pivot, with an elastic member arranged between the holding handle and the pressing handle. The tool is characterized in that a base is fixed to one side of the holding handle, a stamping part is arranged in the base, and the end of the stamping part away from the base is connected to the holding handle and the pressing handle through a pin shaft. By pressing the pressing handle, the pin shaft moves along the limiting hole of the holding handle, thereby driving the stamping part to move and realize punching.

[0005] Furthermore, a slot hole is provided at the upper end of the gripping handle, and the slot hole is communicated with the through cavity of the base. The stamping part is installed into the through cavity of the base through the slot hole and can move along the through cavity.

[0006] Furthermore, the structures at both ends of the stamping part are the same, so that both ends of the stamping part can be used as working surfaces and then switched for use.

[0007] Furthermore, notches are provided at both ends of the stamping piece, so that the head of the stamping piece forms a punching head capable of punching holes.

[0008] Furthermore, the limiting hole is an arc-shaped hole, and the pin passes through the limiting hole to be connected with the pressing handle and the stamping part, and the moving range of the stamping part can be limited by the limiting hole.

[0009] Furthermore, a notch is provided on the outer wall of the base for avoiding the rubber strip.

[0010] Furthermore, the base is connected and fixed to the holding handle by screws.

[0011] Furthermore, the elastic member is a spring, one end of the spring is sleeved on the positioning pin of the holding handle, and the other end of the spring is against the pressing handle.

[0012] Furthermore, a handle pull ring is provided at the lower end of the holding handle. When not in use, the holding handle and the pressing handle can be connected together through the handle pull ring, so as to reduce the volume for storage.

[0013] The utility model has a simple structure and ingenious design. The punching part can be driven to punch holes by pressing the pressing handle. When the pressing handle is released, the punching part can automatically return to its original position under the action of the elastic part. The operation is convenient, fast and with high precision, which meets the requirements of punching holes during hinge installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to better understand the purpose, function and specific design of the present invention, the punching tool for installing hinges of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-Figure 6As shown, the punching tool for installing hinges of the utility model comprises a gripping handle 1 and a pressing handle 2 connected by a pivot 6, an elastic member 4 is arranged between the gripping handle 1 and the pressing handle 2, and the elastic member 4 is a spring, one end of the spring is sleeved on the positioning pin 3 of the gripping handle 1, and the other end of the spring is against the pressing handle 2. A base 7 is fixed to one side of the gripping handle 1, and a stamping part 8 is arranged in the base 7, and the end of the stamping part 8 away from the base 7 is connected to the gripping handle 1 and the pressing handle 2 through a pin 5, and by pressing the pressing handle 2, the pin 5 moves along the limiting hole 11 of the gripping handle 1, thereby driving the stamping part 8 to move, and punching is achieved.

[0026] Notches 83 are provided at both ends of the punching piece 8 so that the head of the punching piece 8 forms a punching head 82 capable of punching holes.

[0027] Specifically, if Figure 3 and Figure 6 As shown, a slot hole 16 is provided at the upper end of the gripping handle 1, and the slot hole 16 is connected to the through cavity 72 of the base 7. The stamping part 8 is inserted into the through cavity 72 of the base 7 through the slot hole 16 and can move along the through cavity 72. The gripping handle 1 is provided with screw holes 15 at the upper and lower ends near the slot hole 16, and the screws 9 are connected and fixed to the base 7 through the screw holes 15.

[0028] like Figure 6 and Figure 7 As shown, the structures at both ends of the stamping part 8 are the same, so that both ends of the stamping part 8 can be used as working surfaces and then switched for use.

[0029] The upper end of the gripping handle 1 is provided with a limiting hole 11 and an axial hole 12 , the upper end of the pressing handle 2 is provided with an upper connecting hole 21 and a lower connecting hole 22 , and both ends of the stamping part 8 are provided with long slot holes 81 .

[0030] During installation, the pivot 6 passes through the shaft hole 12 and the lower connecting hole 22 to connect the gripping handle 1 and the pressing handle 2, the base 7 is connected and fixed to the gripping handle 1 by means of screws 9, the stamping part 8 is inserted into the through cavity 72 of the base 7 through the slot hole 16, and the pin 5 passes through the limiting hole 11, the upper connecting hole 21 and the long slot hole 81 to connect the stamping part 8 with the gripping handle 1 and the pressing handle 2. The limiting hole 11 is an arc-shaped hole, and the moving range of the stamping part 8 can be limited by the limiting hole 11.

[0031] A notch 71 is provided on the outer wall of the base 7 for evading the rubber strip.

[0032] A handle pull ring 13 is provided at the lower end of the holding handle 1. When not in use, the holding handle 1 and the pressing handle 2 can be connected together through the handle pull ring 13 to facilitate storage in a reduced volume.

[0033] When punching, place the punching tool 8 in the groove at the corner of the profile, and then move one of the punching heads 82 at one end of the punching tool 8 to the inner wall of the groove and fit it with the inner wall of the groove. At this time, the base 7 abuts against the outer side of the profile, and the punching head 82 abuts against the inner side of the profile (such as Figure 8 As shown), press the pressing handle 2 to drive the stamping part 8 to move outward to complete the punching. After the punching is completed, release the pressing handle 2, and the stamping part 8 will automatically return to its original position under the action of the elastic part 4. Then move the other punching head 82 at one end of the stamping part 8 to the other side of the groove and fit with the inner wall of the groove. At this time, the base 7 abuts against the outside of the profile, and the punching head 82 abuts against the inside of the profile. Press the pressing handle 2 to drive the stamping part 8 to move outward to complete the punching. After completing the two punching operations, perform another punching operation next to the two holes according to the above method to complete the entire punching operation (as shown). Fig. 9 and Fig.10 as shown).
