[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-5 , the utility model provides an embodiment: a guide base tension adjustment block, comprising a tension block 1;
[0021] A slide groove 2 is provided in the upper end of the tension block 1, a movable block 3 is slidably installed in the slide groove 2, a threaded hole 4 is provided in the movable block 3, and a limit position assembly is provided in the slide groove 2 and at both ends of the movable block 3. The device inserts the movable block 3 into the slide groove 2, and the screw rod is inserted into the threaded hole 4 to fix the tension block 1 and the movable block 3 to the guide base;
[0022] Furthermore, the inner wall of the slide groove 2 and the movable block 3 are both T-shaped, and the upper and lower heights of the slide groove 2 are greater than the upper and lower heights of the movable block 3. This structure is based on the shape and size of the slide groove 2 and the movable block 3, so that when the movable block 3 is inserted into the slide groove 2 and the screw rod inserted into the threaded hole 4 is loosened, the movable block 3 can move up and down in the slide groove 2.
[0023] Furthermore, the limiting assembly includes four groups of protrusions 5 and multiple groups of grooves 6. The four groups of protrusions 5 are symmetrically installed on the front and rear ends of the movable block 3. The multiple groups of grooves 6 are symmetrically opened on the inner wall of the slide groove 2. The four groups of protrusions 5 are inserted into the multiple groups of grooves 6. When the structure is fixedly connected to the movable block 3 and the guide base by inserting a screw rod into the threaded hole 4 and tightening it, the four groups of protrusions 5 at the front and rear ends of the movable block 3 are inserted into the multiple groups of grooves 6, thereby preventing the movable block 3 from sliding in the slide groove 2.
[0024] Furthermore, the opening diameter of the lower end of the multiple groups of grooves 6 is larger than the diameter of the upper inner wall, and the opening of the lower end of the multiple groups of grooves 6 is trumpet-shaped. This structure facilitates the rapid insertion of the four groups of protrusions 5 into the multiple groups of grooves 6 when the four groups of protrusions 5 are aligned with the multiple groups of grooves 6 according to the shape of the opening of the lower end of the multiple groups of grooves 6.
[0025] Furthermore, through holes 7 are symmetrically opened on the left and right sides of the movable block 3, and the openings on the opposite sides of the two groups of through holes 7 are connected to the threaded hole 4. This structure injects rust remover or lubricating oil into the threaded hole 4 through the two groups of through holes 7 to lubricate or remove rust on the screw rod inserted into the threaded hole 4.
[0026] Furthermore, the two groups of through holes 7 are arranged in an inclined shape, and the openings at the opposite ends of the two groups of through holes 7 are higher than the openings at the opposite ends. This structure is arranged in accordance with the shapes of the two groups of through holes 7 so that the rust remover or lubricant injected into the two groups of through holes 7 flows from bottom to bottom through the two groups of through holes 7, thereby fully filling the threaded hole 4.
[0027] Working principle: When the guide base is connected to the elastic block 1, Figure 3 , Figure 4 and Figure 5As shown, the movable block 3 is inserted into the slide groove 2, the screw on the guide base is inserted into the threaded hole 4 on the movable block 3, the screw rotates to drive the movable block 3 to move upward in the slide groove 2, and the movable block 3 moves upward in the slide groove 2 to drive the four groups of protrusions 5 to insert into the multiple groups of grooves 6, so that the movable block 3 is limited in the slide groove 2, and the tension block 1 can be connected to the guide base. After using it for a period of time, the lubricating oil is injected into the threaded hole 4 from the through hole 7, and the lubricating oil is applied to the screw and the threaded hole 4. The above is the entire working principle of the utility model.
[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
