Description

Technical Field

[0001] A clip with adjustable connecting part thickness, belonging to the stationery field, particularly relating to a clip with adjustable connecting part thickness that improves the connection performance between the clip limb and the clamp. Background Technology

[0002] Application number 202320111130.7, entitled "An Invention of a Clip," discloses a clip that holds stationery by changing the thickness of its connecting part. This invention features a slide rail that restricts the sliding of the connecting part of the L-shaped clamping limb, thereby enabling the clamping and releasing operation of the L-shaped clamping limb. It further discloses a clamping clamp and a wire clamping limb, but some problems still exist: 1. Stress causes deformation of the upper and lower walls of the clamp. The clamp defines a slide, which is relatively fragile. Due to the shape of the square tube, the lower wall of the slide opening is more prone to deformation closer to the opening, and even more prone to deformation closer to the middle of the opening. If the slide arm, like the slider arm, is set close to the side wall of the slide, the aesthetic appearance will decrease as the height of the slide increases; moreover, the double-layer setting of the slide arm and slider arm increases the complexity of the process and the difficulty of processing.

[0003] 2. Uneven movement at the connecting part of the slider leg. The clamp defines a sliding track, restricting the movement of the connecting part of the clamp leg; it cannot move up and down or left and right, only forward and backward. However, after the connecting part of the slider leg is divided into two, the movement speed and amplitude of the left and right parts are often different, resulting in an asymmetrical movement state. The locking bolt cannot properly engage with the locking hole of the clamp, leading to failure in clamping the stationery. Summary of the Invention

[0004] After repeated research, the applicant discovered that restricting the left and right connecting parts of the slider separately, rather than restricting the connecting part of the slider as a whole, helps improve the motion performance of the slider. This led to a technical solution that separates the slide rail and reduces its deformation. The specific solution is as follows: Technical Solution 1. A clamp for changing the thickness of a connecting part, comprising a cuboid slide rail with two openings on opposite sides in the middle and multiple side locking holes symmetrically arranged on two other opposite sides, and further comprising two clamping limbs made of steel wire first bent into a frame shape and then bent into an L-shape along the ridge. The opening side of the ridge is the connecting part, and the other side is the clamping part. One clamping limb is a slide rail limb whose connecting part is fixedly connected to the clamp, and the other clamping limb is a symmetrically bent connecting part that mates with the side locking holes of the clamp. The slider limb of the locking bolt is arranged facing the slide rail limb. The locking bolt slides back and forth between the side locking holes of the slide rail, allowing the clamping parts of the slider limb and the slide rail limb to be in both clamped and loose states. Optionally, two central beams that are symmetrically arranged in the middle of the clamp and connected to the upper and lower walls of the slide rail respectively, and simultaneously connecting the two openings of the slide rail, divide the slide rail of the clamp into two side slide rails on the left and right sides and a central slide rail in the middle. The locking bolt of the slider limb is restricted within the corresponding side slide rail.

[0005] The design of the slide rail with a central beam dividing it into left and right side slide rails and a central slide rail restricts the radial movement space of the slider connection, ensuring the two locking bolts maintain axial movement balance and reducing the probability of locking failure. This is the inventive point of this solution. The central beam also increases the slide rail's stability, preventing it from being deformed by the clamping limbs and reducing the dependence of the lower wall on thickness; this is also an inventive point of this solution.

[0006] Beneficial effects: 1. It restricts the movement of the slider joint, keeps the two locking bolts in axial motion balance, and reduces the chance of locking failure; 2. It reduces the dependence of the lower wall on thickness, reduces the probability of deformation of the slide opening under stress, and solves the deformation problem of plastic clamps.

[0007] Technical Solution 2: As the preferred solution of Solution 1, a center beam locking hole is symmetrically provided on each of the two center beams, and locking bolts that cooperate with the center beam locking holes are symmetrically provided on the connecting parts of the slide rail limbs, so that the locking bolts of the slide rail limbs can be locked in the center beam locking holes.

[0008] If the slide rail arm moves like a sliding block arm, the clamping and releasing operations will inevitably be complex. Fixing the slide rail arm helps reduce operational complexity and increases user comfort. For plastic clamps, the heterogeneous fixing process is complex, and for steel clamps, welding increases costs. This solution uses a snap-fit ​​process, which not only eliminates welding but also avoids the production difficulties caused by the material difference between the slide rail arm and the clamp, which is the inventive point of this solution.

[0009] The length of the slide rail limb connection is directly related to the position of the center beam locking hole. The slide rail limb connection enters from one port of the middle slide rail, and the distance from this port to the center beam locking hole determines the length of the slide rail limb connection. The so-called locking bolts that match the center beam locking holes in the slide rail limb connection are from this perspective.

[0010] Beneficial effects: 1. The slide rail is equipped with locking bolts and the center beam is equipped with locking holes, which simplifies the fixing process between the slide rail and the clamp; 2. The fixing of the slide rail and the clamp does not have to be done at the production end, but can be moved to the user end, which provides flexibility for the assembly of the clamp.

[0011] Technical Solution 3: As a preferred embodiment of Technical Solution 2, the upper wall of the clamp near the slide opening also includes an outwardly opening upper locking hole that is adapted to the clamping part of the slide member and matches the locking hole of the middle beam. When the locking bolt of the slide member is locked into the locking hole of the middle beam, the clamping part of the slide member is locked into the upper locking hole of the clamp.

[0012] The upper locking hole serves as the receiving space for the slide rail clamp. It should not be located far from the slide rail end; as long as the slide rail clamp does not protrude from the clamp and can be placed flat on a table, it is sufficient. To ensure a good connection between the locking bolt and the center beam locking hole, the upper locking hole is located on the side of the middle slide rail near the center beam. If the center beam locking hole fixes the front-to-back position of the slide rail, the upper locking hole also fixes the left-to-right position of the slide rail.

[0013] The invention of this solution lies in setting a snap-fit ​​hole on the clamp to ensure the flatness of the slide side of the clamp, so that the slide and the clamp can contact the table at the same time, which facilitates the operation of clamping stationery.

[0014] Beneficial effects: It ensures the flatness of the slide side of the clamp, allowing the slide and the clamp to contact the table simultaneously, making it convenient to clamp stationery.

[0015] Technical Solution 4: As a preferred embodiment of Technical Solution 3, it further includes a slide limb inlet and outlet that is located between the two upper locking holes and enters and exits the upper locking holes, and the slide limb inlet and outlet are connected to the upper locking holes.

[0016] When installing the slide rail, the locking bolts of the slide rail must be engaged in the locking holes of the center beam and the clamping part of the slide rail must be engaged in the upper locking holes of the clamping hoop simultaneously. If the locking holes of the center beam are enlarged, the positional stability of the slide rail will be compromised; if the upper locking holes are widened, the lateral restriction of the upper locking holes on the clamping part of the slide rail will be compromised. However, the elasticity of the slide rail can compensate for this deficiency, which is the inventive point of this solution.

[0017] Beneficial effect: It facilitates the assembly of the slide rail.

[0018] Technical Solution 5: As a preferred embodiment of Technical Solution 2, the left and right side slides also include slide block baffles to prevent the locking bolts of the slide block from accidentally sliding out. The position of the slide block baffles matches the position of the locking holes of the middle beam, so that the locking bolts of the slide block can only disengage from the side slides after overcoming the resistance of the locking bolts of the slide block.

[0019] The slider baffle is installed on the left and right side walls, restricting the slider from entering and exiting the side slideway from the side; the center beam locking hole should open towards the slideway port to release the center beam restriction on the slider entering the side slideway. The cooperation between the center beam locking hole and the slider baffle reduces the risk of accidental detachment of the slider, which is the inventive point of this solution.

[0020] Beneficial effects: The connecting part of the slider can enter the side slide through the locking hole of the middle beam, but it must overcome the resistance of the locking bolt of the slide to disengage, which reduces the risk of the slider falling off accidentally and maintains the integrity of the clamp.

[0021] Technical Solution 6: As a preferred embodiment of Technical Solution 1, the left and right side slides also include slide block baffles to prevent the locking bolts of the slide block from sliding out of the side slides.

[0022] The slider baffle is connected to the clamp sidewall, and its width cannot restrict the elastic engagement between the slider baffle bolt and the clamp side locking hole. If the sum of the width of the slider baffle and the width of the slider bolt is greater than the width of the side slide, then part of the middle beam needs to be cut off. Preferably, the sum of the width of the slider baffle and the width of the slider bolt is less than or equal to the width of the side slide.

[0023] Beneficial effect: The baffle of the slider limb restricts the slider limb from disengaging from the clamp in the normal direction of movement, thus ensuring the integrity of the clamp.

[0024] Technical Solution 7: As a preferred embodiment of Technical Solution 6, an L-shaped slider limb connecting part inlet and outlet is provided on the upper wall of the clamp, and the connecting part of the slider limb is inserted into the slider limb connecting part inlet and outlet.

[0025] Positionally, the slider baffle is closer to the slide opening.

[0026] Beneficial effect: The inlet and outlet of the slider limb connection part are set on the upper wall of the clamp. Although it is possible to enter the slide rail from there, the difference from the conventional direction of movement makes it difficult for it to become a channel for the slider limb to detach from the clamp.
