Description

Technical Field

[0001] The present invention relates to the technical field of clamping tools, and more specifically, to a corrosion-resistant dovetail clamp and a production process thereof. Background Art

[0002] Dovetail clips are widely used in people's daily lives and are often used to clamp and organize documents. Because their overall shape resembles a dovetail when viewed from the side, they are called dovetail clips. Commonly used dovetail clips usually consist of an elastic clip that is connected to the elastic clip and an elastic pressing rod connected to the elastic clip.

[0003] People can separate the clamping ends of the elastic clip by pressing the elastic pressing rods on both sides of the dovetail clip with two fingers. The method of use is relatively convenient. However, in general, the size of the dovetail clip determines the force that people need to use to press the elastic pressing rod. A larger dovetail clip requires a larger force to separate the clamping ends. For groups with less strength, such as children, they do not have enough strength to press the elastic pressing rod to open the clamping ends of the dovetail clip. Therefore, the design of the dovetail clip should also take into account the user experience of this group of people. Summary of the invention

[0009] The present invention is further configured such that: the four connecting rods are all located in the same horizontal plane and the two output gears on the same side of the rolling wheel are respectively meshed with the connecting rods at two ends of the horizontal plane.

[0010] The present invention is further configured as follows: the cross-sectional area of ​​the driving gear is smaller than the cross-sectional area of ​​the transmission gear or the rolling wheel, and the cross-sectional area of ​​the output gear is smaller than the cross-sectional area of ​​the transmission gear.

[0011] The present invention is further configured as follows: a plurality of connecting holes are symmetrically arranged on the two elastic clips, and reinforcing ribs are connected to the two corresponding connecting holes of the two elastic clips. The connection between the reinforcing ribs and the connecting holes is configured as an arc segment, and the center line of the arc segment is on the same straight line as the center axis of the connecting piece.

[0012] The present invention is further configured as follows: the upper end of the connecting shell is rotatably connected to two elastic limit rods, the elastic limit rods are respectively located on both sides of the annular surface of the rolling wheel, a plurality of rotating clamping plates are arranged on the inner side of the connecting shell, a rotating shaft is arranged on the central axis of the rolling wheel and the output gear, the rotating shaft is rotatably connected in the rotating clamping plate, and a plurality of protrusions for increasing the friction coefficient are arrayed on the annular surface of the rolling wheel.

[0013] The present invention is further configured as: a production process for a corrosion-resistant dovetail clamp, the steps of which are as follows:

[0014] S1: Stamping forming: first, the elastic steel sheet is cut by a cutting machine and then put into a punching machine for stamping to obtain an elastic clip. A punching machine with a stamping die of a corresponding shape is used to open a number of connecting holes at the corresponding positions of the elastic clip. Then, a bending machine is used to bend a whole linear elastic steel strip and cut it into an elastic pressing rod and an elastic limiting rod.

[0015] S2: Component processing, using carbon steel as the material through CNC machine tools to form a rotating shaft, a driving gear and a rolling wheel with a protrusion on the outer ring surface, a transmission gear and an output gear with a rotating shaft, a connecting rod and a connecting piece with corresponding shapes and specifications, and a connecting shell that is evenly split into two halves from the middle surface in the height direction.

[0016] S3: Surface galvanizing.

[0017] S4: Assemble components. Classify and gather all the components obtained in S3. First, extend the threaded rod into the guide member along the threaded guide groove to connect the connecting member and the connecting rod together.

Then place the rotating shaft in the transmission gear and the rolling wheel into the corresponding rotating clamping piece. After all the gear sets are installed, connect the other half of the connecting shell to the connecting shell with the gear set installed. Use an electric welding device to weld the edges together. Finally, place the elastic limit rod, elastic pressing rod and reinforcing ribs in the corresponding positions to complete the assembly of the dovetail clamp.

At the same time, by limiting the relative specifications and sizes of the rolling wheel and the gear set, a labor-saving linkage mechanism is formed, so that people can use a relatively small force to rotate the rolling wheel, and drive the connecting rod to move through the gear set. The displacement of the connecting rod can drive the clamping ends of the two elastic clamping pieces to separate or approach each other through the torque force between the wall of the threaded guide groove and the threaded rod. Compared with directly using the elastic pressing rod to open the clamping end of the dovetail clamp, the setting of the opening and closing device requires less force, which provides another feasible method of use for people with less strength.

DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment: A corrosion-resistant dovetail clamp, such as Figure 1-Figure 5 As shown, it includes two elastic clips 1 with a "7"-shaped cross-section, and the clamping ends of the elastic clips 1 are detachably connected to the elastic pressing rods 11. The two elastic clips 1 are connected to each other through an opening and closing device 2. The opening and closing device 2 includes a connecting shell 21 and a rolling wheel 22 rotatably connected to the connecting shell 21. Four connecting rods 23 are slidably connected to the two sides of the connecting shell 21. The rolling wheels 22 and the connecting rods 23 are connected by a gear set 26 that forms a labor-saving linkage mechanism. The two connecting rods 23 on the same side of the elastic clip 1 are connected to an elastic clip 1 through a connecting piece 24. When the connecting rod 23 slides relative to the connecting shell 21, the clamping ends of the two elastic clips 1 can be driven to move away from or closer to each other through the connecting piece 24. Rotating the rolling wheel 22 can drive the connecting rod 23 to slide relative to the connecting shell 21. The two connecting rods 23 slide in opposite directions. Through the design of the opening and closing device 2, in addition to pressing the two elastic pressing rods 11 to open the two elastic clips 1, people are also provided with a method of separating the clamping ends of the two elastic clips 1 by rotating the rolling wheel 22. The rotation of the rolling wheel 22 will drive the connecting rod 23 to slide relative to the connecting shell 21 through the gear set 26 that forms a labor-saving linkage mechanism. The sliding of the connecting rod 23 relative to the connecting shell 21 will drive the connecting member 24 to rotate. The rotation of the connecting member 24 will also drive the elastic clip 1 to rotate relative to the central axis of the connecting member 24, thereby allowing the two connected elastic clips 1 to separate or approach each other. Compared with pressing the two elastic pressing rods 11, the method of rotating the rolling wheel 22 to separate the clamping ends of the two elastic clips 1 requires less force, which is convenient for people with insufficient strength to use the present invention.

[0027] like Figure 1-Figure 5As shown, a section of the elastic clip 1 close to the connecting shell 21 is set as a connecting section 13 forming a polygonal hollow through groove, and the connecting member 24 includes a connecting block 241 placed in the connecting section 13 and embedded in the polygonal hollow through groove of the connecting section 13, and a limiting block 242 located on the side of the connecting section 13 and having a cross-sectional area larger than the cross-sectional area of ​​the polygonal hollow through groove in the connecting section 13. When the connecting member 24 rotates, the end face of the connecting block 241 contacts the groove surface of the connecting section 13 to form the polygonal hollow through groove. Under the action of the stress between the connecting block 241 and the connecting section 13, the connecting member 24 can drive the elastic clip 1 to rotate relative to the central axis of the connecting member 24 through the connecting block 241. The setting of the limiting block 242 limits the degree of connection between the connecting member 24 and the elastic clip 1 through the connecting block 241, making the structure more stable and reasonable.

[0028] like Figure 1-Figure 5 As shown, the rod end of the connecting rod 23 extending out of the connecting shell 21 is fixedly connected with a guide piece 231, and the connecting rod 23 is connected to the connecting piece 24 through the guide piece 231. The connecting piece 24 also includes a threaded rod 243 fixedly connected to the side of the limit block 242 away from the connecting block 241, and the guide piece 231 is provided with a threaded guide groove 2311 corresponding to the threaded rod 243. When the connecting rod 23 slides relative to the connecting shell 21, the connecting piece 24 is driven to rotate through the threaded guide groove 2311 and the threaded rod 243. When the guide piece 231 is driven by the connecting rod 23 to move vertically in the length direction of the connecting rod 23, under the stress between the groove wall of the threaded guide groove 2311 in the guide piece 231 and the threaded rod 243, the displacement of the guide piece 231 causes the threaded rod 243 to move along the threaded guide groove 2311, thereby causing the connecting piece 24 to rotate, and then driving the elastic clip 1 to rotate relative to the connecting piece 24.

[0029] like Figure 1-Figure 5As shown, the gear set 26 includes a driving gear 261 coaxially arranged with the rolling wheel 22 and fixedly connected to the rolling wheel 22, a transmission gear 262 meshing with the driving gear 261, and an output gear 263 fixedly connected to the end of the transmission gear 262 away from the rolling wheel 22. The output gear 263 and the transmission gear 262 are coaxially arranged. The rod end of the connecting rod 23 placed in the connecting housing 21 is provided with a plurality of gear ring grooves 232 along the length direction of the connecting rod 23. The output gear 263 meshes with the connecting rod 23 through the gear ring grooves 232. The four connecting rods 23 are respectively connected to the connecting rod 23 through the gear ring grooves 232. The four gear sets 26 are connected to the same rolling wheel 22. The rotation of the rolling wheel 22 drives the driving gear 261 to rotate. The rotation of the driving gear 261 drives the transmission gear 262 to rotate. The rotation of the transmission gear 262 drives the coaxial output gear 263 to rotate. The rotation of the output gear 263 drives the connecting rod 23 with a gear ring groove 232 to make a linear motion, and drives the guide member 231 to make a linear motion. The guide member 231 moves in between and drives the connection to make a rotational motion through the threaded rod 243, and finally drives the clamping ends of the two elastic clips 1 to move away from or close to each other.

[0030] like Figure 1-Figure 5 As shown, the four connecting rods 23 are all in the same horizontal plane and the two output gears 263 on the same side of the rolling wheel 22 are respectively meshed with the connecting rods 23 at the two ends of the horizontal plane. Through the design of this structure, the connecting rods 23 connected to the same elastic clip 1 can move in opposite directions, so that when the threaded rod 243 is displaced relative to the guide member 231, the two connecting members 24 can rotate in the same direction, thereby driving the elastic clips 1 connected to the two connecting members 24 to rotate toward one direction, thereby rotating in the opposite direction to the elastic clip 1 on the other side. The cross-sectional area of ​​the driving gear 261 is smaller than the cross-sectional area of ​​the transmission gear 262 or the rolling wheel 22, and the cross-sectional area of ​​the output gear 263 is smaller than the cross-sectional area of ​​the transmission gear 262. Through the design of gears of different sizes, a labor-saving structure is finally combined, so that a smaller force is used to do work for a longer time to complete the work that originally took a larger force to do in a shorter time, which is convenient for people with insufficient strength to use the present invention.

[0031] like Figure 1-Figure 5 As shown, a plurality of connecting holes 12 are symmetrically provided on the two elastic clips 1, and a reinforcing rib 121 is connected between the two elastic clips 1 through two corresponding connecting holes 12. The connection between the reinforcing rib 121 and the connecting hole 12 is set as an arc segment, and the center line of the arc segment is on the same straight line as the center axis of the connecting member 24. This design allows that when the present invention is used through the opening and closing device 2, the reinforcing rib 121 will not affect the separation of the two elastic clips 1 when the two elastic clips 1 rotate relative to the connecting member 24. At the same time, the reinforcing rib 121 can enhance the stability and toughness of the structure of the present invention when the present invention is used through the elastic pressing rod 11, thereby improving the service life of the present invention.

[0032] like Figure 1-Figure 5 As shown, the upper end of the connecting shell 21 is rotatably connected to two elastic limiting rods 25, and the elastic limiting rods 25 are respectively located on both sides of the annular surface of the rolling wheel 22. The elastic limiting rods 25 can be rotated to contact the rolling wheel 22, and the rotation of the rolling wheel 22 can be limited, thereby improving the stability of the two elastic clips 1 when the opening and closing device 2 is not in use. A plurality of rotating clamping plates 211 are arranged on the inner side of the connecting shell 21, and a rotating shaft is arranged on the central axis of the rolling wheel 22 and the output gear 263, and the rotating shaft is rotatably connected in the rotating clamping plate 211. A plurality of protrusions for increasing the friction coefficient are arrayed on the annular surface of the rolling wheel 22. The rolling wheel 22 and a plurality of gears can be stably arranged in the connecting shell 21 by rotating the clamping plate 211, thereby enhancing the connection strength of the present invention. The design of the protrusions increases the grip of the rolling wheel 22 and the human hand, making it more convenient for people to use the present invention.

[0033] A production process for a corrosion-resistant dovetail clip, such as Figure 1-Figure 5 As shown, an anti-corrosion dovetail clamp for any one of claims 1 to 8 comprises the following steps:

[0034] S1: Stamping forming, first the elastic steel sheet is cut by a cutting machine and then put into a punching machine for stamping to obtain an elastic clip 1, a punching machine with a stamping mold of corresponding shape is used to open a plurality of connecting holes 12 at the corresponding position of the elastic clip 1, and then a bending machine is used to bend a whole linear elastic steel strip and cut it into an elastic pressing rod 11 and an elastic limiting rod 25.

[0035] S2: Component processing, using carbon steel as the material, through CNC machine tools, precision processing to form a roller 22 with a rotating shaft, a driving gear 261 and a protrusion on the outer ring surface, a transmission gear 262 and an output gear 263 with a rotating shaft, a connecting rod 23 and a connecting piece 24 of corresponding shapes and specifications, and a connecting shell 21 that is evenly split into two halves from the middle surface in the height direction.

[0036] S3: Surface galvanizing. All the components obtained in S1 and S2 are pickled, firstly passed through a plating aid containing ammonium chloride and zinc chloride, and then sent into a molten zinc bath at a temperature of about 450°. After a period of time, the components are taken out and passivated after cooling. The corrosion resistance of the present invention is improved by galvanizing the surface of the components.

[0037] S4: Assemble components. Classify and gather all the components obtained in S3. First, extend the threaded rod 243 into the guide member 231 along the threaded guide groove 2311 to connect the connecting member 24 and the connecting rod 23 together. Then extend the connecting member 24 with the connecting rod 23 into the connecting section 13 of the elastic clip 1 for fixation. Then put the connecting rod 23 with the elastic clip 1 installed into the corresponding position in the connecting shell 21 which is divided into two halves and is set towards the clamping end of the elastic clip 1. Then put the rotating shaft in the transmission gear and the rolling wheel 22 into the corresponding rotating clamping piece 211. After all the gear sets 26 are installed, connect the other half of the connecting shell 21 with the connecting shell 21 with the gear set 26 installed. Use an electric welding device to weld the edges together. Finally, place the elastic limiting rod 25, the elastic pressing rod 11, and the reinforcing rib 121 in the corresponding positions to complete the assembly of the dovetail clamp.

[0038] Working principle: When in use, the elastic limiting rod 25 is moved away from the rolling wheel 22, and force is applied to the rolling wheel 22 to make it rotate. The rolling wheel 22 rotates, driving the driving gear 261 in the connecting housing 21 to rotate, and the connecting rod 23 meshed with the output gear 263 is driven to slide relative to the connecting housing 21 through the transmission gear 262 and the output gear 263 meshed with the driving gear 261. When the connecting rod 23 slides, it drives the guide member 231 to move, and the stress between the groove wall of the threaded guide groove 2311 in the guide member 231 and the threaded rod 243 drives the connecting block 2 The elastic clip 1 connected to the connecting member 24 rotates, thereby approaching or separating the two connected elastic clips 1. Since the cross-sectional area of ​​the driving gear 261 is smaller than the cross-sectional area of ​​the transmission gear 262 or the rolling wheel 22, and the cross-sectional area of ​​the output gear 263 is smaller than the cross-sectional area of ​​the transmission gear 262, a force-saving lever principle is formed, so that a smaller force is used to do work for a longer time to complete the work that originally took a larger force to do in a shorter time. The present invention can be used with less effort, and a convenient and practical dovetail clamp method is provided for people with insufficient strength.

[0039] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
