Description

Technical Field

[0001] This utility model relates to the field of bottle clamp technology, and in particular to a force-saving bottle clamp device that incorporates the lever principle. Background Technology

[0002] Glass bottles are commonly used containers for holding liquids, and despite the influx of various packaging materials into the market, glass containers still hold an important position in beverage packaging. Glass is made primarily from quartz sand, along with other auxiliary materials, which are melted into a liquid state at high temperatures. This liquid is then poured into molds, cooled, cut, and tempered to form the glass bottle. Bottle clamps are a common tool in the glass bottle manufacturing process, mainly used for holding and transporting the formed glass bottles.

[0003] A search revealed a high-temperature resistant bottle clamp for bottle making molds, with authorization announcement number CN213357351U. The clamp includes two opposing clamp bodies, each comprising a shell and a clamping plate within the shell. The shells have openings on opposite sides, and the clamping plates extend into the shells through these openings. The opposing sides of the clamping plates have an arc-shaped structure and are provided with a high-temperature resistant layer. This invention adds a high-temperature resistant layer to the parts of the clamp that contact the glass bottle, improving the clamp's durability and lifespan, avoiding frequent replacements, reducing production and usage costs, and ensuring the normal operation of glass bottle production. It has significant application and promotion value.

[0004] However, the bottle clamp devices mentioned above still have shortcomings. The handles of ordinary bottle clamps are relatively fixed, making it inconvenient to extend the length of the handles. This results in a short power arm length, requiring a large force to clamp the glass bottle firmly. Furthermore, the use of bolts to install and remove the clamping plate and the high-temperature resistant layer makes the installation and removal of the high-temperature resistant layer cumbersome and inconvenient, hindering the replacement of the worn high-temperature resistant layer in the future. Therefore, we propose a force-saving bottle clamp device that incorporates the lever principle to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings mentioned above by proposing a force-saving bottle clamp device that incorporates the lever principle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lever-based, force-saving bottle clamp device includes two clamp heads. The bottom of each clamp head is equipped with an extended force-saving handle mechanism. The extended force-saving handle mechanism includes two connecting plates, two rotating arms, two connecting rods, and two hollow handles. The two rotating arms are respectively mounted on their corresponding connecting plates. The two connecting plates are fixedly connected to the bottom of their respective clamp heads. An arc-shaped plate is provided on the inner side of each clamp head, and a high-temperature resistant pad is fixedly connected to the inner side of the arc-shaped plate. A limiting sleeve is fixedly connected to the outer side of each clamp head. A convenient disassembly and replacement mechanism is provided between the clamp heads, the limiting sleeves, and the arc-shaped plates.

[0008] As a preferred embodiment of this utility model, the lengthening and labor-saving handle mechanism further includes two upper screws, two mounting brackets, and two lower screws. The front side of the connecting plate has an elongated hole. The rear end of the upper screw passes through the mounting bracket and the elongated hole and extends to the rear side of the mounting bracket. The outer side of the upper screw is threaded with a nut. The mounting bracket is slidably sleeved on the outer side of the connecting plate, and the nut is movably abutted against the rear side of the mounting bracket.

[0009] In a preferred embodiment of this invention, two mounting brackets are fixedly connected to one end of the corresponding rotating arm, and two lower screws are threadedly connected to the front side of the corresponding rotating arm. An extension rod is slidably sleeved inside the rotating arm, and multiple slots are provided on the front side of the extension rod. The lower screws are movably engaged in the corresponding slots, and the two rotating arms are rotatably connected to each other by a pin.

[0010] In a preferred embodiment of this invention, the lower end of the extension rod is fixedly connected to the top end of the connecting rod, the hollow handle is threaded onto the outside of the connecting rod, and a rubber sleeve is fixedly fitted onto the outside of the hollow handle.

[0011] As a preferred embodiment of this utility model, the connecting rod has an external thread on its outer side, and the hollow thread is fitted onto the outer side of the external thread.

[0012] As a preferred embodiment of this utility model, the pliers head has an insertion port on one side. The convenient disassembly and replacement mechanism includes an insertion block fixedly connected to the outside of the arc-shaped plate. The insertion block has two sliding grooves, and a through groove is formed between the two sliding grooves. A compression spring is fixedly connected to the inner wall of the side of the two sliding grooves that are close to each other. A sliding plate is fixedly connected to the outer end of the two compression springs. A snap-fit ​​plate is fixedly connected to the outer side of the two sliding plates. A snap-fit ​​interface is formed at the top and bottom of the limiting sleeve. The two snap-fit ​​plates are movably snapped into the corresponding snap-fit ​​interface. The same main rope is fixedly connected to the side of the two sliding plates that are close to each other. A pull rope is fixedly connected to one side of the main rope.

[0013] As a preferred embodiment of this invention, one end of the pull rope is fixedly connected to a handheld ball.

[0014] In a preferred embodiment of this invention, the insert block is slidably fitted inside the insertion port and the limiting sleeve, and the two sliding plates are respectively slidably fitted inside the corresponding sliding grooves.

[0015] In this utility model, the lever-based bottle pliers device allows for greater effort reduction. To achieve this, the nut can be loosened, allowing the mounting bracket to be unfixed to the connecting plate. The mounting bracket can then be moved upwards to reduce the resistance arm, making it more effortless. After adjustment, the nut is tightened to firmly abut against the rear of the mounting bracket, thus fixing it to the connecting plate. The lower screw is then loosened, dislodging it from the slot and allowing the extension rod to be pulled downwards, increasing the length of the rotating arm for greater effort reduction. After adjustment, the lower screw is tightened to engage in the corresponding slot, securing the extension rod. Finally, the hollow handle is rotated; since it is threadedly connected to the connecting rod, the handle can be adjusted downwards to further increase the length of the connecting rod, making it even more effortless. Furthermore, the pliers head, connecting plate, and rotating arm form a lever; by increasing the length of the rotating arm, the power arm is expanded, further reducing effort.

[0016] In this utility model, a lever-based, force-saving bottle clamp device is described. When the high-temperature resistant pad wears out significantly after prolonged use, the pull rope and main rope are pulled outward by holding the ball. The main rope causes the two sliding plates to move closer together, and the two sliding plates cause the two locking plates to move inward and disengage from the locking interface. At this time, the arc plate, insert block, and high-temperature resistant pad can be removed. Then, a new arc plate, insert block, and high-temperature resistant pad are inserted into the insertion port and the limiting sleeve. At this time, the locking plates are automatically pressed back into the sliding groove and squeeze the compression spring. When fully inserted, the locking plates are aligned with the locking interface. Under the elastic force of the compression spring, the two locking plates move outward and lock into the locking interface, thereby fixing the insert block, arc plate, and high-temperature resistant pad.

[0017] This utility model has a reasonable structural design. By increasing the length of the rotating arm and shortening the distance between the rotating arm and the clamp head, the power arm is increased and the resistance arm is shortened. Based on the lever principle, personnel can use less force to firmly clamp the glass bottle, making it more labor-saving. It also facilitates the efficient disassembly and assembly of the high-temperature resistant pad, making it easy to replace the worn high-temperature resistant pad and ensuring the high-temperature resistance effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A lever-based, force-saving bottle clamp device includes two clamp heads 1. The bottom of each clamp head 1 is equipped with an extended force-saving handle mechanism 2. The extended force-saving handle mechanism 2 includes two connecting plates 201, two rotating arms 206, two connecting rods 210, and two hollow handles 212. The two rotating arms 206 are respectively mounted on corresponding connecting plates 201. The two connecting plates 201 are fixedly connected to the bottom of the corresponding clamp heads 1. An arc-shaped plate 4 is provided on the inner side of each clamp head 1. A high-temperature resistant pad 3 is fixedly connected to the inner side of the arc-shaped plate 4. Limit sleeves 5 are fixedly connected to the outer sides of each clamp head 1. A convenient disassembly and replacement mechanism 6 is provided between the clamp heads 1, the limit sleeves 5, and the arc-shaped plate 4.

[0025] Furthermore, refer to Figures 1-3The growth-saving handle mechanism 2 also includes two upper screws 204, two mounting brackets 203, and two lower screws 207. A long slot 202 is provided on the front side of the connecting plate 201. The rear end of the upper screw 204 passes through the mounting bracket 203 and the long slot 202 and extends to the rear side of the mounting bracket 203. A nut 205 is threaded onto the outer side of the upper screw 204. The mounting bracket 203 is slidably fitted onto the outer side of the connecting plate 201. The nut 205 movably abuts against the rear side of the mounting bracket 203. The two mounting brackets 203 are respectively fixedly connected to the corresponding rotating arms. At one end of 206, two lower screws 207 are threadedly connected to the front side of the corresponding rotating arm 206. An extension rod 209 is slidably sleeved inside the rotating arm 206. Multiple slots 208 are opened on the front side of the extension rod 209. The lower screws 207 are movably engaged in the corresponding slots 208. The two rotating arms 206 are rotatably connected to each other by a pin. The lower end of the extension rod 209 is fixedly connected to the top end of the connecting rod 210. A hollow handle 212 is threaded onto the outside of the connecting rod 210. A rubber sleeve 213 is fixedly sleeved on the outside of the hollow handle 212.

[0026] Using the above method: To save effort, loosen nut 205 so that mounting bracket 203 is not fixed to connecting plate 201. Then move mounting bracket 203 upward to reduce resistance arm and make it easier to adjust. After adjustment, tighten nut 205 so that nut 205 firmly abuts against the rear side of mounting bracket 203, thus fixing mounting bracket 203 to connecting plate 201. Loosen lower screw 207 so that lower screw 207 disengages from slot 208 and does not fix extension rod 209. At this time, extension rod 209 can be pulled down to extend rotation. The length of the boom 206 is adjusted to make it more labor-saving. After adjustment, tighten the lower screw 207 so that the lower screw 207 is engaged in the corresponding slot 208, thereby fixing the extension rod 209. Finally, rotate the hollow handle 212. Since the hollow handle 212 is threadedly connected to the connecting rod 210, the hollow handle 212 can be adjusted downward to further increase the length of the connecting rod 210, thus making it more labor-saving. In addition, the clamp head 1, the connecting plate 201 and the boom 206 form a lever. By increasing the length of the boom 206, the power arm is made larger, making it more labor-saving.

[0027] Furthermore, the connecting rod 210 has an external thread 211 on its outer side, and the hollow handle 212 is threaded onto the outer side of the external thread 211, making it convenient to thread the hollow handle 212 onto the outer side of the connecting rod 210.

[0028] Furthermore, refer to Figures 1-4The clamp head 1 has an insertion port 602 on one side. The convenient disassembly and replacement mechanism 6 includes an insertion block 601 fixedly connected to the outside of the arc plate 4. The insertion block 601 has two sliding grooves 611. A through groove 607 is provided between the two sliding grooves 611. A compression spring 610 is fixedly connected to the inner wall of the side of the two sliding grooves 611 that are close to each other. A sliding plate 608 is fixedly connected to the outer end of the two compression springs 610. A snap-fit ​​plate 609 is fixedly connected to the outer side of the two sliding plates 608. The top and bottom of the limiting sleeve 5 have snap-fit ​​interfaces 603. The two snap-fit ​​plates 609 are respectively movably snapped into the corresponding snap-fit ​​interfaces 603. The same main rope 604 is fixedly connected to the side of the two sliding plates 608 that are close to each other. A pull rope 606 is fixedly connected to one side of the main rope 604.

[0029] Using the above solution: When the high-temperature resistant pad 3 wears out significantly after prolonged use, the pull rope 606 and main rope 604 are pulled outward by holding the ball 605. The main rope 604 causes the two slide plates 608 to move closer to each other. The two slide plates 608 cause the two locking plates 609 to move inward and disengage from the locking interface 603. At this time, the arc plate 4, the insert block 601 and the high-temperature resistant pad 3 can be removed. Then, the new arc plate 4, the insert block 601 and the high-temperature resistant pad 3 are inserted into the insertion port 602 and the limiting sleeve 5. At this time, the locking plate 609 is automatically pressed back into the slide groove 611 and squeezes the compression spring 610. When fully inserted, the locking plate 609 is aligned with the locking interface 603. At this time, under the elastic force of the compression spring 610, the two locking plates 609 move outward and lock into the locking interface 603, thereby fixing the insert block 601, the arc plate 4 and the high-temperature resistant pad 3.

[0030] Furthermore, a hand-held ball 605 is fixedly connected to one end of the pull rope 606, which facilitates pulling the pull rope 606.

[0031] Furthermore, the insert 601 is slidably fitted inside the insertion port 602 and the limiting sleeve 5, and the two slide plates 608 are respectively slidably fitted inside the corresponding slide grooves 611, which facilitates the guidance of the slide plates 608 and the insert 601, making their movement more stable.

[0032] In this invention, to reduce effort during use, the nut 205 can be loosened so that the mounting bracket 203 is not fixed to the connecting plate 201. Then, the mounting bracket 203 can be moved upwards to reduce resistance and make it easier to use. After adjustment, the nut 205 is tightened so that it firmly abuts against the rear side of the mounting bracket 203, thus fixing the mounting bracket 203 to the connecting plate 201. The lower screw 207 is then loosened, causing it to disengage from the slot 208 and no longer fix the extension rod 209. At this point, the extension rod 209 can be pulled downwards to... The length of the rotating arm 206 is increased to make it more labor-saving. After adjustment, the lower screw 207 is tightened so that it engages in the corresponding slot 208, thereby fixing the extension rod 209. Finally, the hollow handle 212 is rotated. Since the hollow handle 212 is threadedly connected to the connecting rod 210, the hollow handle 212 can be adjusted downward to further increase the length of the connecting rod 210, thus making it more labor-saving. Furthermore, the pliers head 1, the connecting plate 201, and the rotating arm 206 form a lever. By increasing the length of the rotating arm 206, the power arm becomes larger, making it more labor-saving.

[0033] When the high-temperature resistant pad 3 wears out significantly after prolonged use, the pull rope 606 and main rope 604 are pulled outward by holding the ball 605. The main rope 604 causes the two slide plates 608 to move closer together. The two slide plates 608 cause the two locking plates 609 to move inward and disengage from the locking interface 603. At this time, the arc plate 4, the insert block 601 and the high-temperature resistant pad 3 can be removed. Then, the new arc plate 4, the insert block 601 and the high-temperature resistant pad 3 are inserted into the insertion port 602 and the limiting sleeve 5. At this time, the locking plate 609 is automatically pressed back into the slide groove 611 and squeezes the compression spring 610. When fully inserted, the locking plate 609 is aligned with the locking interface 603. At this time, under the elastic force of the compression spring 610, the two locking plates 609 move outward and lock into the locking interface 603, thereby fixing the insert block 601, the arc plate 4 and the high-temperature resistant pad 3.
