Description
Technical Field
[0001] This utility model relates to the technical field of clamping and fixing equipment, specifically a clamping and fixing device for bonding and welding operations of anti-theft doors and windows. Background Technology
[0002] Security windows refer to a layer of mesh doors and windows with anti-theft protection functions added to the original windows of a building. Common types of security windows are classified by material: stainless steel security windows, color steel security windows, wrought iron security windows, aluminum alloy security windows, zinc steel security windows, steel-plastic composite security windows, and diamond mesh security windows, etc. When welding security doors and windows, clamping and fixing equipment is needed to hold them in place. However, the most common form of clamping and fixing equipment in existing technology is that the screw and threaded bracket drive the clamping frame to hold the door and window frame. However, during welding and operation, the threaded connection is prone to loosening, resulting in reduced welding accuracy and increased defect rate. Furthermore, different clamping brackets are required for welding different models of door and window frames, but changing the clamping brackets is cumbersome and affects the use of the fixing equipment. Therefore, improvements to existing technology are needed. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model adds a fixing plate, guide rod and limiting post inside the mounting base. The limiting post can be driven by the elastic force of spring one to slide into the inside of the connecting cover to limit the connecting cover and the clamping frame. When it is necessary to change the model of the clamping frame, it is only necessary to remove the limiting post from the clamping frame to release the limitation on the clamping frame, thereby making the clamping frame easier to replace.
[0012] 2. This utility model adds a connecting rod, toothed plate, and gear inside the box. After the clamping frame is clamped by the screw engagement between the positive and negative screws and the threaded bracket, the toothed plate can be driven by the elastic force of the second spring to slide into the tooth groove of the gear to limit the positive and negative screws. This prevents the positive and negative screws from rotating again after adjustment. Attached Figure Description

One end of the positive and negative screws 2 is fixedly connected to a rocker arm 13. Inside the rocker arm 13, a handle 14 is installed via bearings.
[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A support base 3 is fixedly installed at the center of the top inside of the box 1. The support base 3 is threadedly connected to the positive and negative screws 2. The support base 3 can support the positive and negative screws 2. The threaded bracket 5 is threadedly connected to the positive and negative screws 2. The mounting base 6 is slidably connected to the box 1. The connecting cover 7 is in slidable contact with the box 1. The positive and negative screws 2 can drive the threaded bracket 5 to move through the threaded engagement with the threaded bracket 5. One end of the spring 12 is fixedly connected to the limiting post 11, and the other end of the spring 12 is fixedly connected to the fixing plate 9. The limiting post 11 is slidably connected to the mounting base 6 and the connecting cover 7. The spring 12 can drive the limiting post 11 to automatically reset through the elastic force.
[0021] Please see Figure 1 , Figure 2 , Figure 3 The locking mechanism 4 includes a gear 41. The gear 41 is fixedly connected to the outer side of the positive and negative screw 2 and the side near the rocker arm 13. Two symmetrically distributed connecting rods 42 are slidably connected inside the box body 1. A toothed plate 43 is fixedly connected to the end of the connecting rod 42 near the gear 41. A baffle 44 is fixedly connected to the outer side of the connecting rod 42. A handle 45 is fixedly connected to the end of the connecting rod 42 away from the toothed plate 43. A second spring 46 is provided on the outer side of the connecting rod 42. A bracket 47 is fixedly connected to the bottom inner side of the box body 1.

[0022] The specific implementation process of this utility model is as follows: In use, press the limiting post 11, which compresses the spring 12. When the limiting post 11 disengages from the current connecting cover 7, the limiting of the connecting cover 7 can be released. Then, remove the current connecting cover 7 and the clamping bracket 8, replace the corresponding clamping bracket 8 and connecting cover 7, and slide the connecting cover 7 to the outside of the mounting base 6. When the connecting cover 7 contacts the box body 1, the spring 12 returns to its original position. The spring 12 can use its elastic force to drive the limiting post 11 to slide into the interior of the connecting cover 7, thus completing the mounting process. Replace the clamp 8, then pull the handle 45. The handle 45 drives the toothed plate 43 to move through the connecting rod 42 and compresses the spring 46. When the toothed plate 43 disengages from the tooth groove of the gear 41, the limit on the positive and negative screw 2 can be released. Then, the positive and negative screw 2 is driven to rotate through the handle 14 and the rocker arm 13. During the rotation, the positive and negative screw 2 can drive the threaded frame 5 and the mounting base 6 to move through the threaded engagement with the threaded frame 5. During the movement, the mounting base 6 can drive the clamping frame 8 to clamp the door and window frame.
[0023] After clamping is completed, release the handle 45, and the second spring 46 will return to its original position. The second spring 46 can drive the toothed plate 43 to return to its original position through its elasticity. The toothed plate 43 will be re-engaged into the inside of the gear 41, which will complete the limiting of the positive and negative screws 2, thereby making the clamping of the door and window frame more stable.
