They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example 1: Refer to Figures 1-9 A reusable simple pile head protective sleeve includes a protective sleeve 1 for protecting the pile head. The protective sleeve 1 is equipped with buckles 2 for fixing its two ends around the pile head. The buckles 2 are installed on the outside of one end of the protective sleeve 1, and the other end of the protective sleeve 1 passes through the buckles 2 and is locked to the buckles 2.

[0032] In this utility model, a pre-designed standardized protective sleeve 1 set is used. Two types of protective sleeves 1 with different heights of 5cm and 10cm are made to determine the exposed height of the pile head. They are then fixed and installed with buckles 2. The entire protective sleeve 1 is made of 2mm thick galvanized iron sheet, which greatly improves the protection. The exposed height of the pile head is determined by the protective sleeve 1, and then the pile head is broken. This improves the construction efficiency of pile head breaking and better protects the forming quality of the pile head, avoiding the need for labor to repair it later.

[0033] Example 2: Basically the same as Example 1, but further: Refer to Figures 1-9 A reusable simple pile head protective sleeve, the buckle 2 includes a buckle frame 3 installed on the outer wall of one end of the protective sleeve 1, the buckle frame 3 has a horizontal through slot 7, the slot 7 is slidably connected to the outer wall of the protective sleeve 1.

[0034] The inner wall of slot 2 7 has a slot 3 8 at the front end. The front end of the protective sleeve 1 is fixedly installed with a plug 2 9. The outer wall of plug 2 9 is provided with a locking device between slot 2 7 and slot 3 8. The top of slot 3 8 has an installation space. During assembly, the buckle 2's frame 3 is fixedly installed on one side of the front end of the protective sleeve 1. The other end of the protective sleeve 1 extends into the frame 3, and the two ends of the protective sleeve 1 are closed and fixed by the locking device, and looped around the pile head.

[0035] In this utility model, a pre-designed standardized protective sleeve 1 set is used. Two types of protective sleeves 1 with different heights of 5cm and 10cm are made to determine the exposed height of the pile head. They are then fixed and installed with buckles 2. The entire protective sleeve 1 is made of 2mm thick galvanized iron sheet, which greatly improves the protection. The exposed height of the pile head is determined by the protective sleeve 1, and then the pile head is broken. This improves the construction efficiency of pile head breaking and better protects the forming quality of the pile head, avoiding the need for labor to repair it later.

[0036] Specifically: The locking component includes a ratchet 11, which is located within the installation space and rotatably connected to the inner wall of the installation space; the top of the second insert 9 has a horizontal array of teeth 10, which mesh with the ratchet 11; a pawl 12 is provided on one side of the top of the ratchet 11, and a rotating shaft 13 is rotatably connected to the inner side of the top of the pawl 12, which is fixedly connected to the inner wall of the installation space at the top of the third slot 8; a thrust spring 15 is connected to the outer side of the pawl 12, which is fixedly connected to the inner wall of the installation space at the top of the third slot 8; an arc-shaped groove 17 is provided at the front end of the frame 3, the center of the arc-shaped groove 17 corresponds to the axis of the rotating shaft 13, and a lever 14 is slidably connected to the inner wall of the arc-shaped groove 17, one end of which extends into the installation space and is fixedly connected to the outer wall of the pawl 12; auxiliary gears 16 are provided on both sides of the ratchet 11, which are rotatably connected to the inner wall of the installation space and mesh with the teeth 10;

[0037] A card plate 4 is provided at the connection between the rear side of the card frame 3 and the protective sleeve 1. Top grooves 5 are provided on both sides of the top and bottom of the card plate 4. Top blocks 6 are fixedly connected to both sides of the top and bottom of the rear end of the card frame 3. The top blocks 6 correspond to the top grooves 5.

[0038] Working principle: The card frame 3 is clamped to one side of the outer wall of the protective sleeve 1 by the card plate 4, and is fixedly connected to the inner wall of the top groove 5 by bolts passing through the top block 6;

[0039] The other end of the protective sleeve 1 is passed through slot 2 7, which simultaneously drives the insert block 2 9 to pass through slot 3 8. At the same time, the ratchet 11 and the auxiliary gear 16 are driven to rotate through the meshing teeth 10. The ratchet 11 rotates clockwise, which pushes the pawl 12 to rotate counterclockwise outward, squeezing the thrust spring 15, so that the protective sleeve 1 is wrapped around the pile head. When the protective sleeve 1 is pulled outward, the ratchet 11 rotates counterclockwise, and the pawl 12 is locked in the groove of the ratchet 11, which restricts and fixes the ratchet 11, and at the same time restricts the protective sleeve 1.

[0040] When it is necessary to remove the protective cover 1, pull the lever 14 to move along the arc groove 17, causing the pawl 12 to rotate counterclockwise, separating the pawl 12 from the ratchet 11, releasing the restriction on the counterclockwise rotation of the ratchet 11. Then pull the protective cover 1 to the right. Figure 8 As shown, the ratchet 11 and auxiliary gear 16 rotate counterclockwise, separating the protective sleeve 1 from the card frame 3.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
