Detailed Implementation
[0019] To more clearly illustrate the purpose, technical solution, and advantages of the embodiments of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description will be provided. Obviously, the described embodiments are some, but not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0020] Examples of embodiments of this utility model Figures 1 to 3As shown, an adjustable clamp includes a mounting bracket 1 for mounting the clamp at a corresponding workstation. A fixing block 2 is mounted on the mounting bracket 1. A guide post 3, perpendicular to the top surface of the fixing block 2, is provided on the top surface of the fixing block 2. The fixing block 2 is mounted on the lower part of the mounting bracket 1. The guide post 3 is vertical, and a sliding block 4 is slidably fitted onto the guide post 3. This means that the sliding block 4 has a through hole that matches the guide post 3, through which the guide post 3 passes. The sliding block 4 is directly above the fixing block 2 and slides on the guide post 3, approaching or moving away from the fixing block 2. The interaction between them clamps or releases the golf club. In this case, the mounting bracket 1 is selected as an L-shaped bracket. The structure means it has a horizontal end in the horizontal direction and a vertical end in the vertical direction. The fixing block 2 is installed on the horizontal end of the mounting bracket 1, and the guide post 3 is set on the top surface of the fixing block 2 near the vertical end of the mounting bracket 1. That is, the guide post 3 is set on the inner side of the top surface of the fixing block 2, so as not to affect the clamping of the golf club. In order to ensure the smooth sliding of the sliding block 4, two guide posts 3 are arranged parallel to each other, that is, two guide posts 3 are arranged side by side on the left and right sides of the inner side of the top surface of the fixing block 2. Each guide post 3 is fitted with a telescopic spring 30 between the sliding block 4 and the fixing block 2. The telescopic spring 30 is fitted on the guide post 3, which can buffer the rapid downward impact of the sliding block 4 and also make the sliding block 4 move within the telescopic spring 30. Under the elastic force of 0, it slides upward, returning to the state before the sliding block 4 was compressed; for the installation of the guide post 3 on the fixed block 2, the fixed block 2 is provided with a mounting hole 21 for installing the guide post 3. The telescopic spring 30 is sleeved on the guide post 3 in the mounting hole 21 and a part of it extends out of the mounting hole 21, which means that the outer diameter of the telescopic spring 30 matches the diameter of the mounting hole 21. The lower part of the telescopic spring 30 is in the mounting hole 21, and the upper part of the telescopic spring 30 extends into the sliding block through hole. At this time, the sliding block through hole is set with a structure where the diameter is smaller at the top and larger at the bottom, which can prevent the telescopic spring 30 from passing through the sliding block through hole. At this time, the sliding block through hole and the mounting hole 21 provide the telescopic spring 30 with room to move, preventing the telescopic spring from moving out when the clamp is closed. The effect of spring 30 on clamping; rubber blocks 5 are provided on the opposing surfaces of sliding block 4 and fixed block 2. Each rubber block 5 has a V-shaped groove 50 with an obtuse angle at its apex. The rubber blocks 5 have a certain degree of hardness and can also undergo elastic deformation to a certain extent, facilitating use. The obtuse angle of the V-shaped groove 50 expands its coverage area. The space enclosed by the two V-shaped grooves 50 forms a placement space for the golf club, thus maintaining clamping force and stability when clamping the golf club. The deformation of the rubber blocks 5 also increases the resistance to rotation of the golf club during clamping, making the clamping more stable; a first rotating shaft 6 with its axis perpendicular to the extension direction of the V-shaped groove 50 is horizontally provided on the top surface of the sliding block 4. Figure 1 and Figure 3 As shown, the V-shaped groove 50 extends in the left-right direction, and the first rotating shaft 6 is set in the front-back direction, parallel to the horizontal end of the mounting bracket 1. Regarding the arrangement of the first rotating shaft 6, one option is to extend protrusions on both the front and back sides of the top surface of the sliding block 4, forming a U-shaped structure with the two protrusions and the top surface of the sliding block 4. The two ends of the first rotating shaft 6 are then mounted on the opposing surfaces of the two protrusions, positioned at one end of the U-shaped structure opening. Another option is to provide a top surface groove 40 on the top surface of the sliding block 4, with the top surface groove 40 and the V-shaped groove... The extension direction of the slot 50 is the same, extending in the left and right direction. The first rotating shaft 6 is set on the two side walls of the top surface groove 40, which are parallel to the extension direction of the V-shaped slot 50. The length of the top surface groove 40 is set to be greater than the length of the rotating block 7. The two ends of the first rotating shaft 6 are installed on the front and rear side walls of the top surface groove 40, respectively, near the openings and in the middle position in the left and right direction. The mounting bracket 1 is pivotally connected to the rotating block 7 directly above the first rotating shaft 6. The rotating block 7 is pivotally connected to the vertical end of the mounting bracket 1 and is located above the sliding block 4. The rotation axis of the rotating block 7 is directly above the axis of the first rotating shaft 6. The surface of the rotating block 7 corresponding to the first rotating shaft 6 is an involute curved surface 70. If the involute cam is divided into two halves along the line connecting the starting point, ending point and the center of the involute base circle, one half can be selected as the rotating block 7. The rotation axis of the rotating block 7 is set on the side of the starting point of the involute. The involute curved surface 70 is provided with multiple arc-shaped grooves 71 with minor arc cross-sections that can engage with the first rotating shaft 6 at equal intervals along the rotation direction. That is to say, the arc-shaped grooves 71 are arranged along the starting point of the involute. The rotating block 7 is set at equal intervals from the endpoint to the rotation point. The cross-section of the arc-shaped groove 71 is in the shape of a minor arc to facilitate the rotation of the rotating block 7, while at the same time it can match and engage with the first rotating shaft 6 to position the rotation of the rotating block 7. The rotating block 7 is equipped with a rotating handle 8, which is used to control the rotation of the rotating block 7. The rotating handle 8 is located on the end point side of the involute curve of the rotating block 7. The rotating handle 8 can be detachably mounted on the rotating block 7. For example, an external thread can be provided on the rotating handle 8, and a threaded hole can be provided on the rotating block 7. Then, the rotating handle 8 can be threaded into the threaded hole. In use, the golf club is placed in the V-shaped groove 50 of the rubber block 5 on the fixed block 2, and then the rotating handle 8 is turned to make the rotating block 7 rotate. The rotating block 7 applies a downward force on the first rotating shaft 6, which in turn pushes the sliding block 4 to slide downward to clamp the golf club.
[0021] Further improvements, such as Figure 1 and Figure 2As shown, the involute surface 70 has a positioning groove 72 at one end adjacent to the rotating block 7 and the mounting bracket 1. The positioning groove 72 is a groove with a semi-circular cross section. The positioning groove 72 is located at the starting point of the involute. When not in use, the positioning groove 72 is engaged on the first rotating shaft 6 to keep the rotating block 7 and the sliding block 4 in a stable state.
[0022] Further improvements include ensuring that the sliding distance of the sliding block 4 is no greater than 2 / 3 of the length of the involute surface 70, thus preventing excessive rotation of the rotating block 7 and maintaining the stability of the fixture structure.
[0023] Further improvements, such as Figure 1 and Figure 3 As shown, both the sliding block 4 and the fixed block 2 have a first groove 20 on their opposing surfaces. The rubber block 5 is installed in the first groove 20 and the end of the V-shaped groove 50 protrudes from the opening end of the first groove 20. In this way, when the two rubber blocks 5 abut against each other, there will still be a gap between the sliding block 4 and the fixed block 2, which will prevent the sliding block 4 and the fixed block 2 from colliding and maintain the stability of the structure.
[0024] Further improvements, such as Figure 1 As shown, the rotating block 7 is pivotally connected to the mounting bracket 1 via a second rotating shaft, which can be a bolt. Coaxial through holes are provided on the rotating block 7 and the mounting bracket 1. Finally, the bolt is passed through the through hole and connected to the nut. A stop block 73 is also provided between the rotating block 7 and the mounting bracket 1, which is sleeved on the second rotating shaft. The setting of the stop block 73 ensures that there is a certain space between the vertical ends of the rotating block 7 and the mounting bracket 1. The guide post 3 is set on the fixed block 2 at a position corresponding to this space. The guide post 3 will not affect the rotation of the rotating block 7. The stop block 73 is a cylindrical stop block.
[0025] Although the present invention has been described in detail above with general description and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
