Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing jigs for woodworking, and particularly relates to a simple clip. Background Art

[0002] As we know, when processing and manufacturing woodworking parts, some jigs are usually used so that multiple components can be placed and combined together according to the shape and position requirements of the design, and then the multiple components are connected together with screws, nails, glue, etc. to form the required component products. According to the size of the components to be clamped, the jigs are usually divided into three types: large, medium, and small. Among them, the typical structure of the "large" jig is an F-shaped jig; while the typical structure of the "small" furniture is a "clip". Specifically, it includes two clamping parts that can rotate relative to each other. One end of the two clamping parts is a clamping end, and the other end is a control end. The middle of the two clamping parts is rotatably connected and is provided with a torsion spring. When in use, the two control ends are squeezed to separate the two clamping ends from each other, and then the control ends are released. Relying on the elastic force of the torsion spring, the two clamping ends tightly clamp the component.

[0003] Such a clip has the characteristics of simple structure and convenient use, but there are still the following technical defects: Since the clamping force of the two clamping ends is realized by relying on the elastic force of the torsion spring, the magnitude of the clamping force is inversely proportional to the clamping distance. When the size of the clamped component is small, it will cause the clamping force to be too small; when the size of the clamped component is small, it will cause the acting force on the control end to be too large, resulting in inconvenience in use. Summary of the Invention

[0004] The purpose of the present invention is to provide a simple clip that can not only conveniently clamp small-sized components, but also effectively avoid the problem of unstable clamping force magnitude, facilitating reliable clamping of components.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A simple clip includes two clamping parts that are rotatably connected in the middle. One end of the two clamping parts is a clamping end for clamping components, and the other end is a control end for holding by hand. A locking mechanism is provided between the control ends of the two clamping parts. The locking mechanism has a locking state and a release state. When the clamping ends of the two clamping parts clamp the component, the locking mechanism is in the locking state. At this time, the relative positions of the two clamping parts remain unchanged, and the clamping end and the component are in interference fit; when the locking mechanism is in the release state, the two clamping parts can rotate relative to each other, and the component is separated from the clamping part.

[0007] The present invention is a fixture suitable for clamping small-sized components. When clamping a component, first, the locking mechanism is in a released state. At this time, the two clamping ends can be separated from each other through the control ends of the two clamping parts, and the component is located between the two clamping ends. Then, the two clamping ends are brought closer to each other through the two control ends to clamp the component. Next, the locking mechanism is in a locked state, so that the relative positions of the two clamping parts remain unchanged, and an interference fit is formed between the clamping ends and the component to clamp the component tightly.

[0008] In particular, the clamping ends of the two clamping parts clamp the component through the locking mechanism in the locked state, which can effectively avoid the problem of unstable clamping force size that is likely to occur when clamping the component by elastic force or the holding force of the hand, facilitating the reliable clamping of the component.

[0009] Preferably, the two clamping parts are in an X-cross shape. When the two control ends approach each other, the two clamping ends approach each other and clamp the component; when the two control ends move away from each other, the two clamping ends move away from each other and release the component.

[0010] Since the two clamping parts are in an X-cross shape, the distance between the two control ends is proportional to the distance between the two clamping ends, which is conducive to intuitively judging the state of the clamping ends through the control ends.

[0011] In particular, when clamping a component, we should reduce the distance between the two clamping ends. Correspondingly, the distance between the two control ends is correspondingly reduced, and then the locking mechanism bears a tensile force. It can be understood that for components with the same rigidity, the tensile force that can be borne will be much greater than the force that can be borne.

[0012] Preferably, the locking mechanism includes a connection head provided at the control end and a pull rod connected between the two connection heads. The two ends of the pull rod are threadedly connected to the corresponding connection heads, and the thread directions at both ends of the pull rod are opposite.

[0013] As mentioned above, the locking mechanism mainly bears tensile force, and the pull rod can bear sufficient tensile force and avoid its bending deformation. When we rotate the pull rod, since the thread directions at both ends of the pull rod are opposite, the connection heads can be pulled towards the middle simultaneously, and then the clamping ends approach each other to clamp the component.

[0014] Preferably, at least one end of the pull rod passing through the connection head is provided with a regular hexagon rotating section, and a ratchet wrench is sleeved on the rotating section.

[0015] The regular hexagon rotating section facilitates rotating the pull rod through tools such as a wrench, and the ratchet wrench facilitates continuously rotating the pull rod in one direction.

[0016] Preferably, the locking mechanism includes an L-shaped connecting card slot arranged at the control end and a pull rod connected between the two control ends. Both ends of the pull rod are located in the corresponding connecting card slots. A fastening nut is provided at the end of the pull rod extending out of the connecting card slot, and the thread directions at both ends of the pull rod are opposite.

[0017] Since the control end is provided with an L-shaped connecting card slot, it is convenient for the pull rod to enter the connecting card slot, and at the same time, the self-dislodging of the pull rod can be avoided. When the pull rod is rotated, the fastening nuts at both ends can be tightened simultaneously, and then the two control ends are pulled towards the middle to clamp the zero component.

[0018] Preferably, a washer is provided on the pull rod between the control end and the fastening nut. One end of the washer abutted against the control end is hemispherical, and a hemispherical positioning groove is provided on the control end close to the washer.

[0019] It can be understood that when the two control ends approach or separate from each other, the opposite end faces of the two control ends cannot always remain parallel. That is to say, the fastening nut cannot always completely abut against the control end. For this reason, we set a washer on the pull rod between the control end and the fastening nut. A hemispherical positioning groove is provided on the control end close to the washer, and one end of the washer abutted against the control end is hemispherical. In this way, no matter what state the opposite end faces of the two control ends are in, one hemispherical end face of the washer can always be located in the hemispherical positioning groove of the control end, and the other flat end face of the washer can always abut against the fastening nut.

[0020] Preferably, the two clamping parts are connected in an 8-shape, and a clamping block is hinged at the clamping end.

[0021] The clamping parts connected in an 8-shape can be symmetrically opened or closed. The clamping block is beneficial to increasing the contact area with the zero component.

[0022] Therefore, the present invention has the following beneficial effects: it can conveniently clamp small-sized zero components, effectively avoid the problem of unstable clamping force magnitude, and facilitate the reliable clamping of zero components. Description of the Drawings

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] As Figure 1 shown, a simple clip is a woodworking fixture suitable for clamping small-sized components. Specifically, it includes two clamping parts 1, which are rotatably connected in the middle. One end of the two clamping parts is a clamping end 11 for clamping the component, and the other end is a control end 12 for hand holding. A locking mechanism is provided between the control ends of the two clamping parts. The locking mechanism has a locking state and a release state. When the clamping ends of the two clamping parts clamp the component, the locking mechanism is in the locking state. At this time, the relative positions of the two clamping parts remain unchanged, and the clamping end has an interference fit with the component; when the locking mechanism is in the release state, the two clamping parts can rotate relative to each other, and the component is separated from the clamping part.

[0028] It should be noted that the interference fit between the clamping end and the component means that the clamping end closely abuts the component.

[0029] When it is necessary to rotate the clamping part, the locking mechanism can be made to be in the release state: when it is necessary to clamp the component, the locking mechanism is made to be in the locking state. At this time, the relative positions of the two clamping parts remain unchanged. That is to say, the clamping ends of the two clamping parts clamp the component through the locking mechanism in the locking state, which can effectively avoid the problem of unstable clamping force size that is likely to occur when clamping the component through a torsion spring or the gripping force of the hand, and is convenient for reliably clamping the component.

[0030] As a preferred solution, the two clamping parts cross to form an X shape, so that the distance between the two control ends is proportional to the distance between the two clamping ends, which is beneficial to intuitively judge the state of the clamping ends through the control ends. When the two control ends approach each other, the two clamping ends approach each other and clamp the component; when the two control ends move away from each other, the two clamping ends move away from each other and release the component.

[0031] Preferably, the two clamping parts are connected to form an 8 shape, and the clamping parts connected to form an 8 shape can be symmetrically opened or closed. In addition, a clamping block 111 is hinged at the clamping end, which is beneficial to increasing the contact area with the component. Since the clamping end is hinged to the clamping block, it can ensure that the clamping block always closely abuts the component.

[0032] Furthermore, the locking mechanism includes a connecting head 121 provided at the control end and a pull rod 2 connected between the two connecting heads. The two ends of the pull rod are threadedly connected to the corresponding connecting heads, and the thread directions at both ends of the pull rod are opposite.

[0033] It can be understood that when the control ends approach each other and then clamp the component, the pull rod bears tensile force, thus avoiding bending deformation. When we rotate the pull rod, since the thread directions at both ends of the pull rod are opposite, the connecting heads can be pulled towards the middle simultaneously, and then the clamping ends approach each other to clamp the component. On the contrary, when the pull rod is rotated in the reverse direction, the connecting heads at both ends are separated from each other, so that the locking mechanism enters the release state.

[0034] Furthermore, at least one end of the pull rod passing through the connecting head is provided with a regular hexagon rotating section 21, and a ratchet wrench 3 is sleeved on the rotating section.

[0035] When the ratchet wrench is sleeved on the rotating section, the pull rod can be conveniently rotated to make the two connecting heads approach each other. When it is necessary to release the component, the ratchet wrench can be sleeved on the rotating section in the reverse direction and then rotated in the reverse direction, so that the locking mechanism enters the release state.

[0036] It should be noted that the threaded connection part between the pull rod and the connecting head is cylindrical, and the rotating section can be an inscribed regular hexagon of the cylinder to facilitate the rotating section to pass through the connecting head.

[0037] As another preferred solution, as Figure 2 shown, the locking mechanism includes a connection card slot 122 arranged at the control end, a pull rod connected between the two control ends. Both ends of the pull rod are located in the corresponding connection card slots. A fastening nut 4 is provided at the end of the pull rod extending out of the connection card slot, and the thread directions at both ends of the pull rod are opposite. The connection card slot includes a horizontal part and a vertical part, and the horizontal part and the vertical part are connected into an L-shaped connection card slot. The pull rod can first enter the horizontal part and then enter the vertical part to prevent the pull rod from slipping out by itself. When the pull rod is rotated, the fastening nuts at both ends can be tightened simultaneously, and then the two control ends are pulled towards the middle to clamp the component.

[0038] Furthermore, a washer 5 is provided on the pull rod between the control end and the fastening nut. One end of the washer abuting against the control end is hemispherical, and a hemispherical positioning groove 123 is provided on the control end close to the washer.

[0039] When the two control ends approach or separate from each other, the opposite end faces of the two control ends cannot always remain parallel. That is to say, the fastening nut cannot always completely abut against the control end. Therefore, we set a washer on the pull rod between the control end and the fastening nut. A hemispherical positioning groove is provided on the control end close to the washer, and one end of the washer abuting against the control end is hemispherical. In this way, no matter what state the opposite end faces of the two control ends are in, the hemispherical end face of the washer can always be located in the hemispherical positioning groove of the control end, and the other flat end face of the washer can always abut against the fastening nut.
