Specific embodiments

[0023] The present utility model will be further described in detail below in conjunction with the drawings and embodiments.

[0024] See Figures 1 to 6 As shown, an auxiliary device for plastering the external corners of building door openings includes: a pressing assembly for pressing and fixing wooden strips and a C-shaped connecting plate 8. Two pressing assemblies are arranged in parallel up and down. The pressing assembly includes: a U-shaped support 1, a mounting shaft 2, a torsion spring 3, a sleeve 4, an inner tube 5, and a pressure rod 7. The front and rear ends of the inner side of the upper part of the U-shaped support 1 are fixedly connected to the front and rear ends of the mounting shaft 2. A torsion spring 3 is sleeved on the mounting shaft 2. The two ends of the torsion spring 3 face left and right. The two ends of the torsion spring 3 are respectively fixedly connected to one end of two sleeves 4. The other end of the sleeve 4 is slidably connected to one side of the inner tube 5. A locking mechanism for fixing the position of the inner tube 5 is arranged on the sleeve 4. The other end of the inner tube 5 is vertically fixedly connected to the pressure rod 7. The front and rear ends of the two U-shaped supports 1 on the upper and lower sides are symmetrically fixedly connected to two C-shaped connecting plates 8.

[0025] In this embodiment, the middle part of the bottom end of the lower U-shaped support 1 is fixedly connected to one end of a vertical screw rod 9, and the other end of the vertical screw rod 9 is fixedly connected to a support seat 10. The entire device can be well supported by the support seat 10 to avoid the occurrence of the situation where the pressure rod 7 slides down.

[0026] In this embodiment, a U-shaped lower support frame 11 is arranged below the lower U-shaped support 1, and a U-shaped upper support frame 14 is arranged below the upper U-shaped support 1. The U-shaped upper support frame 14 is located above the lower U-shaped support 1. Four connecting rods 15 are symmetrically and fixedly connected to the left and right sides of the front and rear ends of the U-shaped lower support frame 11 and the U-shaped upper support frame 14. The included angle between the ends of the two torsion springs 3 is synchronously adjusted through the U-shaped upper support frame 14 and the U-shaped lower support frame 11. The widths of the left and right sides at the top ends of the U-shaped lower support frame 11 and the U-shaped upper support frame 14 are both greater than the distance between the inner ends of the two sleeves 4 when the two sleeves 4 are arranged at a 180° angle in the same group. The top ends of the U-shaped lower support frame 11 and the U-shaped upper support frame 14 are respectively in pressing contact with the two sleeves 4 in their respective corresponding pressing assemblies. A vertically penetrating circular hole is formed in the middle of the bottom end of the U-shaped lower support frame 11, and a vertical screw 9 passes through and is fixedly connected in the circular hole. A limiting pin 12 is fixedly connected to one side of the inner wall of the circular hole. A vertical sliding groove 901 matching the limiting pin 12 is formed on the outer wall of the vertical screw 9, and the limiting pin 12 is vertically slidably connected in the vertical sliding groove 901. A threaded cylinder 13 is threadedly connected to the vertical screw 9, and the threaded cylinder 13 is located below the U-shaped lower support frame 11. Anti-slip threads are arranged on the outer wall of the threaded cylinder 13. By rotating the threaded cylinder 13, the U-shaped lower support frame 11 can be driven to synchronously move up and down with the U-shaped upper support frame 14, so as to facilitate the smooth placement of the entire device into the door opening during installation.

[0027] In this embodiment, the locking mechanism is a locking knob 6. The locking knob 6 includes a screw part and a handle part. The screw part is perpendicularly welded and fixed to the handle part. A threaded hole is formed on the side of the sleeve 4 away from the torsion spring 3. The screw part is threadedly connected to the threaded hole and presses against the outer wall of the inner tube 5 corresponding to the sleeve 4. Through the arrangement of the locking knob 6, the inner tube 5 can be fixed after being stretched to an appropriate length.

[0028] When the device is in use, first adjust the stretching lengths of the four inner tubes 5 according to the width of the door opening. After the adjustment is completed, fix them through the locking knob 6. Then, rotate the threaded cylinder 13 clockwise to drive the U-shaped lower support frame 11 to synchronously move upward with the U-shaped upper support frame 14. The top ends of the U-shaped lower support frame 11 and the U-shaped upper support frame 14 are respectively in pressing contact with the two sleeves 4 in their respective corresponding pressing assemblies. Continue to move upward so that the distance between the two pressure rods 7 in the same group is less than the width of the door opening. At this time, place the entire device in the middle of the door opening. Then, rotate the threaded cylinder 13 counterclockwise to drive the U-shaped lower support frame 11 to synchronously move downward with the U-shaped upper support frame 14. At this time, the four pressure rods 7 respectively press against the wooden strips on the left and right sides of the inner wall of the door opening. Then, the plastering construction of the door opening corner can be carried out. Through the arrangement of this device, the quality risk of formwork swelling of the wooden strips can be reduced, the quality perception can be improved, the plastering efficiency can be increased, and it is not affected by any construction environment, which is convenient for construction and can be used repeatedly, achieving the effect of cost reduction and efficiency increase.
