Description

Technical Field

[0001] This utility model relates to the field of glass bottle inspection, and in particular to a glass bottle protective stopper that is easy to remove. Background Technology

[0002] The vertical load test for glass bottles is used to measure the force that a glass bottle can withstand in the vertical direction. In the vertical load test, the glass bottle is placed on a pressure testing device, which can gradually apply a vertically downward force. The force that can withstand is usually set with a standard value. The standard value is usually based on various vertical pressures that may be encountered in actual use, such as the weight pressure when stacked or the pressure that may be suffered during transportation. If the glass bottle does not break when the force specified by the standard value is reached, then the glass bottle is judged to be qualified. This judgment standard means that the bottle can safely withstand external pressure under the expected use conditions without structural damage.

[0003] However, when the pressure bar of the pressure testing device applies pressure to the mouth of the glass bottle, a certain impact force is generated at the moment of contact with the mouth of the glass bottle. This impact force can cause the mouth of the glass bottle to break. In order to avoid breakage, a protective plug with an elastic structure is usually used. The elastic structure can absorb the impact force applied to the mouth of the bottle and convert it into elastic potential energy, thereby reducing the impact force directly transmitted to the mouth of the bottle and greatly reducing the damage to the mouth of the glass bottle.

[0004] Protective stoppers typically consist of a plunger and a stopper head. However, due to the elasticity of the protective stopper, when the pressure rod is applied to it, the plunger may be pushed inwards, potentially blocking the bottle opening. As the plunger moves inwards, the stopper head (the top part of the stopper) will press against the bottle opening, reducing the contact area available for the operator to pull out the plunger. This makes it difficult for the operator to find enough space to grip the stopper head and apply force, causing inconvenience in use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a glass bottle protective stopper that is easy to remove. The purpose is to solve the technical problem that due to the inward movement of the stopper, the stopper head will be tightly pressed against the bottle mouth, resulting in a reduction in the contact area of ​​the stopper head that the operator can use to pull out the stopper, making it difficult for the operator to find enough space to hold the stopper head and apply force, thus causing inconvenience in use.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A removable glass bottle stopper includes a stopper head, a stopper post at the bottom of the stopper head, a first contact surface at the top of the stopper head for contacting the pressure rod of a pressure testing device, a second contact surface at the bottom of the stopper head for contacting the bottle neck, the stopper head being elastic, a first protective ring at the second contact surface being elastic, a placement groove at the top of the first contact surface, a first connecting hole inside the placement groove, a second connecting hole inside the stopper post communicating with the first connecting hole, the second connecting hole penetrating the bottom of the stopper post, a pull block inside the placement groove, a movable pull rod at one end of the pull block, the movable pull rod slidingly engaging with the first and second connecting holes, one end of the movable pull rod protruding downwards beyond the second connecting hole, and a pull plate at one end of the movable pull rod located below the stopper post.

[0008] When the stopper is pressed into the bottle neck, the stopper head will be tightly against the bottle neck. Due to the placement groove, when the pressure rod of the testing device applies pressure to the first contact surface, since the glass bottle is placed vertically, the pull block is located inside the placement groove. The pressure rod of the testing device will only contact the first contact surface and will not squeeze the pull block located in the placement groove. After the test is completed, the operator can turn the glass bottle upside down. Due to the sliding engagement between the movable pull rod and the first and second connecting holes, the other end of the movable pull rod will protrude from the first connecting hole under the action of gravity. At this time, the pull block will be exposed outside the stopper head. The operator can use the pull block to drive the movable pull rod and the pull plate upward. Since the pull plate is located below the stopper, the pull plate will pull the stopper out of the bottle neck, so that the stopper and the stopper head can be easily separated from the glass bottle even when the stopper head is tightly against the bottle neck.

[0009] Furthermore, in this application, the top of the plunger is provided with a mounting base, the interior of the mounting base is provided with a third connecting hole, the third connecting hole connects the first connecting hole and the second connecting hole, the bottom of the second contact surface is provided with a fixing groove, and the mounting base is detachably connected to the fixing groove.

[0010] The third connecting hole inside the mounting base connects to the first and second connecting holes, forming a through channel, which facilitates the installation and operation of the movable pull rod. The fixing groove at the bottom of the second contact surface is detachably connected to the mounting base, allowing the stopper to be adjusted and replaced according to different sizes of glass bottles.

[0011] Furthermore, in this application, the plug head has a first fixing hole on both sides, the first fixing hole is connected to the fixing groove, the mounting base has a second fixing hole on both sides, a fixing bolt is inserted in the first fixing hole, and the fixing bolt is threadedly engaged with the adjacent second fixing hole.

[0012] By setting corresponding first and second fixing holes on the plug head and the mounting base respectively, and connecting the two with fixing bolts, the plug head and the plug plunger are detachably connected through bolt connection. This makes it easy to replace the mounting base when needed, thus improving the maintainability and service life of the product.

[0013] Furthermore, in this application, the bottom of the second contact surface is provided with a plurality of first fixing slots, and one side of the first protective ring is provided with a plurality of first mounting posts. The first mounting posts are elastic, and the plurality of first mounting posts are respectively engaged with the plurality of first fixing slots.

[0014] Furthermore, in this application, a second protective ring is provided on the top of the first contact surface, and the second protective ring is elastic.

[0015] Furthermore, in this application, the top of the first contact surface is provided with a plurality of second fixing slots, and one side of the second protective ring is provided with a plurality of second mounting posts. The second mounting posts are elastic, and the plurality of second mounting posts are respectively engaged with the plurality of second fixing slots.

[0016] Furthermore, in this application, a pull groove is provided at the bottom of the plunger, the shape of the pull groove matches the shape of the pull plate, and the pull plate is inserted into the pull groove.

[0017] Furthermore, in this application, a sealing block is provided in the placement groove, the sealing block is elastic, and the sealing block is located above the pull block.

[0018] Furthermore, in this application, the top of the sealing block is provided with a handle.

[0019] Furthermore, in this application, the materials of the first mounting post, the second mounting post, the first protective ring, and the second protective ring are rubber.

[0020] This utility model has the following beneficial effects:

[0021] When the stopper is pressed into the bottle neck, the stopper head will be tightly against the bottle neck. Due to the placement groove, when the pressure rod of the testing device applies pressure to the first contact surface, since the glass bottle is placed vertically, the pull block is located inside the placement groove. The pressure rod of the testing device will only contact the first contact surface and will not squeeze the pull block located in the placement groove. After the test is completed, the operator can turn the glass bottle upside down. Due to the sliding engagement between the movable pull rod and the first and second connecting holes, the other end of the movable pull rod will protrude from the first connecting hole under the action of gravity. At this time, the pull block will be exposed outside the stopper head. The operator can use the pull block to drive the movable pull rod and the pull plate upward. Since the pull plate is located below the stopper, the pull plate will pull the stopper out of the bottle neck, so that the stopper and the stopper head can be easily separated from the glass bottle even when the stopper head is tightly against the bottle neck.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In vertical load testing of glass bottles, protective plugs with elastic structures are typically used to protect the bottle neck from damage. These plugs absorb the impact force applied by the pressure testing device's lever, converting it into elastic potential energy, thus reducing the impact force directly transmitted to the bottle neck and significantly lowering the risk of damage. However, because the plug is elastic, when pressed by the lever, the plug's plunger may move inwards, causing it to block the bottle neck. Simultaneously, this inward movement can cause the plug tip to press tightly against the bottle neck, reducing the contact area available for the operator to pull out the plunger. In this situation, the operator may find it difficult to find enough space to grip the plug tip and apply force, making the plug difficult to remove.

[0033] In the quality inspection department of a glass manufacturing company, hundreds of glass bottles undergo vertical load testing daily. Inspectors use pressure testing equipment to apply vertical pressure to the bottles with protective stoppers to simulate the stacking weights or handling pressures that might be encountered in actual use. During the test, the stoppers effectively protect the bottle openings from damage. However, when it's time to remove the stoppers for the next round of testing, inspectors find that the stopper has penetrated deep into the bottle, with the stopper head tightly fitted to the bottle opening. Due to a lack of space to grip, inspectors have to use additional tools or spend more time and effort to remove the stopper. This not only reduces testing efficiency but also increases the risk of accidentally damaging the glass bottles during handling.

[0034] Reference Figures 1-5 In some specific embodiments, an easy-to-remove glass bottle protective stopper includes a stopper head 1, a stopper post 2 at the bottom of the stopper head 1, a first contact surface 3 at the top of the stopper head 1 for contacting the pressure rod of a pressure testing device, a second contact surface 4 at the bottom of the stopper head 1 for contacting the bottle mouth of the glass bottle, the stopper head 1 being elastic, a first protective ring 5 at the second contact surface 4 being elastic, a placement groove 9 at the top of the first contact surface 3, a first connecting hole 10 inside the placement groove 9, a second connecting hole 12 inside the stopper post 2 communicating with the first connecting hole 10, the second connecting hole 12 penetrating the bottom of the stopper post 2, a pull block 8 inside the placement groove 9, a movable pull rod 6 at one end of the pull block 8, the movable pull rod 6 slidingly engaging with the first connecting hole 10 and the second connecting hole 12, one end of the movable pull rod 6 protruding downwards outside the second connecting hole 12, and a pull plate 7 at one end of the movable pull rod 6 located below the stopper post 2.

[0035] With the above technical solution, when the stopper 2 is pressed into the mouth of the glass bottle, the stopper 1 will be tightly against the mouth of the glass bottle. Due to the placement groove 9, when the pressure rod of the testing device applies pressure to the first contact surface 3, since the glass bottle is placed vertically at this time, the pull block 8 is located inside the placement groove 9. The pressure rod of the testing device will only contact the first contact surface 3 and will not squeeze the pull block 8 located in the placement groove 9. After the test is completed, the operator can turn the glass bottle upside down. Since the movable pull rod 6 slides with the first connecting hole 10 and the second connecting hole 12, the other end of the movable pull rod 6 will protrude from the first connecting hole 10 under the action of gravity. At this time, the pull block 8 will be exposed outside the stopper 1. The operator can use the pull block 8 to drive the movable pull rod 6 and the pull plate 7 to move upward. Since the pull plate 7 is located below the stopper 2, the pull plate 7 will drive the stopper 2 to be pulled out from the mouth of the bottle, so that the stopper 2 and the stopper 1 can be easily separated from the glass bottle even when the stopper 1 is tightly against the mouth of the bottle.

[0036] Specifically, the diameters of the first connecting hole 10 and the second connecting hole 12 should be slightly larger than the diameter of the movable pull rod 6 to ensure that the movable pull rod 6 can slide smoothly. The diameter of the pull plate 7 should be larger than the diameter of the second connecting hole 12, but smaller than the inner diameter of the bottle mouth, so that it can be pulled out without getting stuck in the bottle. The pull block 8 can be designed in a shape that is easy to grip, such as round or hexagonal, and the diameter can be between 10-20 mm.

[0037] Specifically, the length of the movable lever 6 needs to take into account the length of the stopper 2 and the possible insertion depth. For example, if the length of the stopper 2 and the stopper head 1 is 30 mm, the length of the movable lever 6 can be designed to be 40-50 mm to ensure that even if the stopper 2 is fully pressed into the bottle, the pull plate 7 can still be located below the stopper 2. The thickness of the pull plate 7 can be between 1-3 mm to provide sufficient strength without adding too much weight.

[0038] It should be noted that the main purpose of the stopper 1 and the stopper 2 is to protect the mouth of the glass bottle, that is, to replace the mouth of the glass bottle in contact with the pressure rod of the testing equipment. Therefore, the stopper 2 and the stopper 1 do not need to consider how to seal the glass bottle.

[0039] In addition, since the second contact surface 4 is provided with a first protective ring 5, which is elastic, when the stopper 1 comes into contact with the mouth of the glass bottle, the elasticity of the first protective ring 5 protects the mouth of the glass bottle, thus preventing the stopper 1 from having a hard collision with the mouth of the glass bottle.

[0040] Reference Figures 1-5 In some specific embodiments, the top of the plunger 2 is provided with a mounting base 19, and the interior of the mounting base 19 is provided with a third connecting hole 11, which connects to the first connecting hole 10 and the second connecting hole 12. The bottom of the second contact surface 4 is provided with a fixing groove 21, and the mounting base 19 and the fixing groove 21 are detachably connected.

[0041] Through the above technical solution, the third connecting hole 11 inside the mounting base 19 connects the first connecting hole 10 and the second connecting hole 12 to form a through channel, which facilitates the installation and operation of the movable pull rod 6. The fixing groove 21 at the bottom of the second contact surface 4 is detachably connected to the mounting base 19, so that the stopper 2 can be adjusted and replaced according to different specifications of glass bottles.

[0042] Reference Figures 1-5 In some specific embodiments, the plug head 1 has first fixing holes 17 on both sides, the first fixing holes 17 are connected to the fixing groove 21, the mounting base 19 has second fixing holes 20 on both sides, the first fixing holes 17 are fitted with fixing bolts 18, and the fixing bolts 18 are threaded into the adjacent second fixing holes 20.

[0043] Through the above technical solution, by setting corresponding first fixing holes 17 and second fixing holes 20 on the plug head 1 and the mounting base 19 respectively, and connecting the two with fixing bolts 18, the plug 2 and the plug head 1 are detachably connected by bolt connection, which makes it easy to replace the mounting base 19 when needed, thereby improving the maintainability and service life of the product.

The first mounting posts 13 are elastic, and the plurality of first mounting posts 13 are respectively engaged with the plurality of first fixing slots 14.

[0045] Through the above technical solution, the first fixed slot 14 provides a fixed position for the first mounting post 13, and the elastic design of the first mounting post 13 ensures the tightness and reliability of the snap-fit. This design not only simplifies the installation process, but also facilitates the disassembly and replacement of the first protective ring 5, which is beneficial to the maintenance and cleaning of the plug head 1.

[0046] Reference Figures 1-3 In some specific embodiments, a second protective ring 15 is provided on the top of the first contact surface 3, and the second protective ring 15 is elastic.

[0047] Through the above technical solution, the setting of the second protective ring 15 increases the buffering effect between the first contact surface 3 and the pressure rod of the pressure detection device, which can effectively reduce the direct impact of the pressure rod of the pressure detection device on the first contact surface 3, thereby protecting the first contact surface 3 from damage.

[0048] Reference Figures 1-3 In some specific embodiments, the top of the first contact surface 3 is provided with a plurality of second fixing slots 23, and one side of the second protective ring 15 is provided with a plurality of second mounting posts 16. The second mounting posts 16 are elastic, and the plurality of second mounting posts 16 are respectively engaged with the plurality of second fixing slots 23.

[0049] Through the above technical solution, multiple second mounting posts 16 can be engaged with multiple second fixing slots 23 respectively. This design improves installation stability, enhances reliability, facilitates disassembly and assembly, and prevents detachment.

[0051] Through the above technical solution, when the pull block 8 pulls the movable pull rod 6, the movable pull rod 6 drives the pull plate 7 to engage with the pull groove 22, thereby positioning the contact position between the pull plate 7 and the stopper 2, avoiding direct contact between the pull plate 7 and the glass bottle, and reducing wear and damage.

[0052] Reference Figure 4 In some specific embodiments, a sealing block 24 is provided in the placement groove 9. The sealing block 24 is elastic and is located above the pull block 8.

[0053] With the above technical solution, when the stopper 1 and the stopper 2 are not needed, the sealing block 24 engages with the placement groove 9. The presence of the sealing block 24 can also improve the sealing performance of the glass bottle protective stopper and prevent external air or impurities from entering the interior of the stopper 2.

[0055] Reference Figures 1-5 In some specific embodiments, the first mounting post, the second mounting post, the first protective ring 5, and the second protective ring 15 are made of rubber.
