Description

Technical Field

[0001] This invention belongs to the technical field of daily necessities, and specifically refers to a fixing device. Background Technology

[0002] A clip is used to hold sheets and mattresses in place, preventing them from shifting or wrinkling. However, commonly used clips are fitted over the sheets and mattresses, such as the invention patent with patent number 2019214292183, entitled "A Sheet Holding Device." Although this patent is applicable to all households and convenient to use, because it is fitted over the sheets and mattresses, the clips need to be fitted over the sheets and mattresses from both ends, and then the clips need to be moved to the middle to reach the desired holding position. A certain amount of force is also required to move it to the desired holding position. Therefore, it is not possible to clamp directly from the desired position and it is also laborious. Summary of the Invention

[0003] The purpose of this invention is to provide a fixing device that uses a first clamp and a second clamp to hinge together, and uses a lever to open the first clamp and the second clamp, so that the user can clamp at any position and use it easily and conveniently. It does not require a hook on the lever to keep the first clamp and the second clamp closed, and solves the problem that existing fixing clamps cannot be directly clamped from the desired position.

[0004] The objective of this invention is achieved as follows:

[0005] A fixing device includes a first clamp and a second clamp, the second clamp being hinged to the first clamp and allowing relative rotation; the first clamp and the second clamp close together to clamp an object; the fixing device further includes:

[0006] A paddle is rotatably mounted on the clamping plate; the paddle has an unlocked state and a locked state.

[0007] The paddle has the following characteristics:

[0008] The actuating end is used to apply external force to switch the lever between the unlocked and locked states; and

[0009] The pushing end is at least partially located on the rotation trajectory of the two ends of the clamping plate;

[0010] When the lever is in the locked state, the pushing end of the lever and the inner end of the second clamping plate are pressed together in the circumferential direction to maintain the locked state, so that the first clamping plate and the second clamping plate remain closed.

[0011] Preferably, the inner side of the inner end is provided with a guide slope, which is interference-fitted with the push end, so that the paddle needs to enter or exit the locking state under a certain external force.

[0012] Preferably, the rear end of the pushing end is located at the front end of the clamping plate two, and a guide is provided on the upper inner wall of the clamping plate two. When the pushing end is driven to move downward by the force of the actuating end, the rear end of the pushing end rotates from the inner end to the inner end face of the guide, thereby switching the actuating plate from the locked state to the unlocked state.

[0013] Preferably, an L-shaped guide groove is provided between the guide member and the inner end, and the rear end of the pushing end pushes the second clamping plate to rotate outward along the guide groove, thereby putting the paddle in the unlocked state and then opening the first clamping plate and the second clamping plate.

[0014] Preferably, one side of the paddle is formed with a relief groove, and the outer wall surface of the relief groove is at least partially located on the movement trajectory of the inner end of the clamp when the two clamps are opened;

[0015] As the opening angle of clamp one and clamp two increases, the inner end further extends into the clearance groove.

[0016] Preferably, a groove is provided in the middle of the first clamping plate, and the groove is an open groove extending to the inner end of the second clamping plate; the lever is rotatably installed in the groove;

[0017] The pushing end extends to the inner end of the clamping plate two.

[0018] Preferably, the first rotating shaft is provided on both sides of the paddle, and the first rotating shaft is located between the paddle end and the push end;

[0019] The clamp is provided with a cavity, and the paddle is rotatably disposed in the cavity;

[0020] The two side walls of the chamber are provided with grooves, and the rotating shaft passes through the groove and rotates within the groove.

[0021] Preferably, the two side walls of the chamber are provided with protrusions, and an abutment is provided between the actuating end and the rotating shaft, and the abutment abuts against the protrusion.

[0022] Preferably, a connecting groove is provided at one front end of the clamping plate, and the actuating end is placed in the connecting groove in the locked state to restrict the actuating end from rotating inward.

[0023] Preferably, a space is provided between the connecting groove and the actuating end to facilitate the user toggling the actuating end;

[0024] Or / and, the inner wall of the toggle end is provided with a recess to facilitate the user toggling the toggle end;

[0025] The clamping plate is provided with connecting plates on both sides, and one end of the connecting plate is provided with a mounting hole;

[0026] The clamping plate is provided with two rotating shafts on both sides, and the rotating shafts pass through the mounting holes and rotate within the mounting holes;

[0027] Both the first and second clamping plates are semi-circular arc plates, thus conforming to the curvature of the mattress edges.

[0028] The outstanding and beneficial technical effects of this invention compared to the prior art are:

[0029] 1. The present invention uses clamp plate one and clamp plate two to be hinged together, and clamp plate one and clamp plate two are opened by a lever, so that the user can clamp and tighten them at any position, which is very easy and convenient to use, just by turning the lever.

[0030] 2. The present invention uses a convex strip to push the clamp plate to rotate outward along the guide, thereby making the rear end of the pushing end contact the guide and thus preventing the paddle from getting stuck.

[0031] 3. The guide of the present invention has an L-shaped guide groove, which increases the contact area with the pushing end and prevents the pushing end from detaching from the guide.

[0032] 4. The present invention designs the first and second clamping plates as semi-circular arc plates to fit the curvature of the mattress edges.

[0033] 5. The present invention places the actuating end in the connecting groove so that the outer end of the actuating end and the outer end of the clamp are on the same plane, thereby providing the user with a comfortable feel.

[0034] 6. The present invention facilitates the user to operate the toggle end by means of the space between the connecting groove and the toggle end and / or the recess in the inner wall of the toggle end.

[0035] 7. In this invention, when clamping plates one and two are closed and the lever is in the locked state, the pushing end and the inner end of clamping plate two are pressed in the circumferential direction; therefore, it is not necessary to hook clamping plates one or two with the lever to achieve the closing of clamping plates one and two. This makes clamping items easier and less strenuous.

[0036] 8. The design of the clearance groove in this invention provides a space for rotation at the inner end, thereby adjusting the angle of rotation at the inner end by adjusting the size of the clearance groove, and ultimately adjusting the opening angle of clamping plate one and clamping plate two, thus expanding the range of applicable product thicknesses of this fixing device.

[0051] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0052] like Figures 1-4 As shown, a fixing device includes a first clamp 1 and a second clamp 2, which are hinged to each other. Therefore, in actual use, the first clamp 1 and the second clamp 2 can be opened and closed relative to each other.

[0053] Meanwhile, a chamber 13 is provided on the clamp 1, and a lever 3 is rotatably mounted inside the chamber 13. The two ends of the lever 3 are a lever end 31 and a push end 32, respectively. Figure 2 As shown, the rear end of the pushing end 32 is located at the front end of the clamping plate 2, and a guide 21 is provided on the upper inner wall of the clamping plate 2.

[0054] Therefore, in actual use, when the actuating end 31 is forced to move the pushing end 32 downward, the rear end of the pushing end 32 pushes the guide 21, that is, the rear end of the pushing end 32 can push the clamping plate 2 outward along the guide 21, thereby opening the clamping plate 1 and the clamping plate 2, allowing the user to clamp and tighten them at any position, thus providing convenience for the user. At the same time, it is very easy and convenient to use, simply by actuating the lever 3.

[0055] In other words, in this embodiment, such as Figure 1-10 As shown, when the lever 3 is in the locked state, the pushing end 32 of the lever and the inner end 24 of the second clamp 2 are pressed together in the circumferential direction to maintain the locked state, so that the first clamp 1 and the second clamp 2 remain closed. Therefore, it is not necessary to lock the first clamp or the second clamp with the lever to keep the first clamp and the second clamp closed. This makes clamping objects easier and less strenuous.

[0056] This is because, in existing technologies, one solution involves using a hook at the end of a lever to engage either clamp 1 or clamp 2, thereby ultimately keeping clamp 1 and clamp 2 closed. However, this solution requires considerable force to engage the hook at the end and also generates noise.

[0057] At the same time, when opening clamp 1 and clamp 2, it is also necessary to disengage the hook from the connecting part. This disengagement process requires a relatively large force and will also generate noise.

[0058] In this embodiment, the paddle only needs to be pressed against the connecting groove 11 to keep the first clamp and the second clamp closed, eliminating the need for a hook structure. This results in no noise and makes both locking and unlocking easier and less strenuous.

[0059] Furthermore, to prevent the paddle 3 from loosening and the clamps 1 and 2 from suddenly opening, the rear end of the push end 32 is placed against the front side of the upper end of the clamp 2, that is, the push end 32 and the clamp 2 are close to each other to form an interference fit, thereby restricting the rotation of the paddle 3 and preventing the clamps 1 and 2 from suddenly opening.

[0060] In other words, in this embodiment, a guide slope 25 is provided on the inner side of the inner end 24. The guide slope 25 is interference-fitted with the push end 32, so that the paddle 3 needs to enter or exit the locking state under a certain external force.

[0061] Therefore, in actual use, a certain amount of force is required to rotate the lever 3, thereby opening the clamping plates 1 and 2. Furthermore, this invention can also be used for sealing snacks to prevent moisture, and for clamping other household items, such as tablecloths or curtains. Thus, the fixing device in this embodiment can clamp even thin snack bags, thick tablecloths and curtains, and even thicker mattress edges, achieving clamping for both thin and thick items.

[0062] like Figures 2-4 and Figures 7-8 As shown, a protrusion 33 is provided on the inner wall of the rear end of the pushing end 32. Therefore, when the actuating end 31 is forced to move the pushing end 32 downward, the protrusion 33 first abuts against the guide 21, thereby pushing the clamping plate 2 to rotate outward along the guide 21, and then the rear end of the pushing end 32 contacts the guide 21, thus avoiding jamming.

[0063] This is because relying solely on the pushing end 32 may cause jamming. That is, when the pushing end 32 moves down, the clamping plate 2 and the pushing end 32 will move to the right, which may cause jamming. Therefore, it is necessary to first open the clamping plate 1 and clamping plate 2 a little through the protrusion 33, and then push through the pushing end 32 to avoid jamming.

[0064] like Figure 10 As shown, the guide member 21 has an L-shaped guide groove 22, and the rear end of the pushing end 32 pushes the clamping plate 2 to rotate outward along the guide groove 22, thereby opening the clamping plate 1 and the clamping plate 2.

[0065] Compared to a flat surface, the L-shaped guide groove 22 has a larger contact area with the pushing end 32. Moreover, during the guiding process, the rear end of the pushing end 32 will eventually fall into the groove of the L-shaped guide groove 22, thereby preventing the pushing end 32 from detaching from the guide member 21.

[0066] In addition, in this embodiment, such as Figures 1-10 As shown, a relief groove 37 is formed on one side of the paddle 3, and the outer wall surface of the relief groove 37 is at least partially located on the movement trajectory of the inner end 24 when the clamp 2 opens;

[0067] As the opening angle of clamp 1 and clamp 2 increases, the inner end 24 extends further into the clearance groove 37.

[0068] In other words, when the lever 3 starts to rotate and is in the unlocked state, the lever 3 has already rotated a certain angle, and the angle of the clearance groove 37 has changed compared to the locked state. Specifically, as follows... Figure 2-4 As shown, the clamp 1 and clamp 2 change from a closed and clamped state to an open state.

[0069] In particular, such as Figure 4 As shown, at this time, the inner end 24 of the clamp 2 has been located in the relief groove 37 after passing through the set rotation trajectory. In extreme cases, the inner end 24 can abut against the outer wall surface of the relief groove 37.

[0070] The advantage of setting the clearance groove 37 is that by changing the depth of the clearance groove 37, the degree to which the inner end 24 extends into the clearance groove 37 can be changed, thereby changing the opening angle of the clamping plate 1 and the clamping plate 2, thus clamping items of different thicknesses.

[0071] like Figures 1-10 As shown, both the first plate 1 and the second plate 2 are semi-circular arc plates, and the edges of the mattress are generally rounded. Therefore, the semi-circular arc plates can better fit the curvature of the mattress edges. The design of the semi-circular arc plates can also be used to organize the wires by coiling the wires between the first plate 1 and the second plate 2.

[0072] like Figures 2-5 As shown, the front end of the clamp 1 has a connecting groove 11, and the actuating end 31 is placed in the connecting groove 11 to restrict the actuating end 31 from rotating inward, and to make the outer end of the actuating end 31 and the outer end of the clamp 1 are on the same plane, thus providing the user with a comfortable feel.

[0073] At the same time, it is convenient for the user to move the toggle end 31. A space 12 can be provided between the connecting groove 11 and the toggle end 31 to facilitate the user to move the toggle end 31.

[0074] Alternatively, the inner wall of the toggle end 31 may be provided with a recess 34 to facilitate the user toggling the toggle end 31. Or a combination of both may be used.

[0075] Combination Figures 5-9 It can be seen that the rotational connection between the paddle 3 and the clamp 1 is achieved by firstly, the paddle 3 has a rotating shaft 35 on both sides, and the rotating shaft 35 is located between the paddle end 31 and the push end 32. At the same time, grooves 14 are provided on both sides of the chamber 13.

[0076] Therefore, in actual use, the lever 3 can be rotatably mounted on the clamp plate 1 by means of the structure in which the rotating shaft 35 passes through the groove 14 and rotates within the groove 14.

[0077] Meanwhile, in order to limit the position of the paddle 3, protrusions 15 are provided on both sides of the chamber 13, and abutment 36 is provided between the paddle end 31 and the rotating shaft 35. The abutment 36 abuts against the protrusions 15, thereby limiting the position of the paddle 3 and preventing the paddle 3 from moving up and down.

[0078] Combination Figure 6 , Figure 9 and Figure 10It can be seen that the rotational connection between clamping plate 1 and clamping plate 2 is achieved by firstly, connecting plates 16 are provided on both sides of clamping plate 1, and one end of the connecting plate 16 is provided with a mounting hole 17. At the same time, rotating shafts 23 are provided on both sides of clamping plate 2.

[0079] In actual use, the clamping plate 2 can be rotatably mounted on the clamping plate 1 by means of the structure in which the rotating shaft 23 passes through the mounting hole 17 and rotates within the mounting hole 17.
