Description

Technical Field

[0001] This utility model relates to the field of bottle opening device technology, and in particular to a reagent bottle inner stopper opening clamp with anti-splash function. Background Technology

[0002] Chemical reagents are among the most common raw materials in chemical experiments, and they are mostly stored in glass bottles. Currently, when opening glass bottles containing chemical reagents during experiments, rubber gloves must be worn. After unscrewing the outer cap, the thumbnail should be inserted between the outer edge of the inner stopper and the bottle mouth, and the thumb and forefinger should be used together to pinch the inner stopper and pull it upwards to open it.

[0003] A search revealed a publication (announcement) number: CN207046814U, which discloses a bottle-opening device for glass bottles containing liquid chemical reagents. This device relates to the technical field of bottle-opening devices and includes a bottle clamp and a bottle opener. A first and second clamping branch of the bottle clamp are respectively fixed to the front ends of a first and second handle of the bottle clamp, and are hinged at the connection point to form the bottle clamp. Similarly, a first and second clamping branch of the bottle opener are respectively fixed to the front ends of a first and second handle of the bottle opener, and are hinged at the connection point to form the bottle opener. During the bottle-opening operation, the hand holds the handle away from the chemical reagent. A protective cover shields the bottle opening and neck, preventing chemical reagents from splashing onto the hand and avoiding direct contact between the chemical reagents and the hand, thus ensuring the operator's safety. The bottle clamp secures the glass bottle, allowing the bottle opener to accurately and conveniently enter between the outer edge of the stopper and the bottle opening, making opening the bottle convenient, fast, and safe.

[0004] Although the above solution uses a bottle clamp to fix the glass bottle body, and the bottle opener can accurately and conveniently enter between the outer edge of the stopper and the bottle mouth, making opening the bottle convenient, fast and safe, the outer edge of the inner stopper is relatively thin and fits tightly with the mouth of the glass reagent bottle. Excessive clamping force can easily cause the inner stopper to break, resulting in reagent leakage. Therefore, we propose a reagent bottle inner stopper opening clamp with anti-splash function. Utility Model Content

[0005] The main purpose of this utility model is to provide a reagent bottle inner stopper opening clamp with anti-splash function. By setting the opening unit and anti-splash unit, it solves the problem that the outer edge of the inner stopper is thin and fits tightly with the mouth of the glass reagent bottle. Excessive clamping force can easily cause the inner stopper to break, resulting in reagent leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A reagent bottle stopper opening pliers with anti-splash function includes an opening unit, a connecting unit disposed inside the opening unit, a gripping unit disposed below the opening unit, and an anti-splash unit disposed above the opening unit. The plugging unit includes a first clamp, a second clamp disposed on the side of the first clamp, a first semi-threaded rod installed on the top of the first clamp, a second semi-threaded rod installed on the top of the second clamp, and rubber sleeves installed on the peripheral sides of the first semi-threaded rod and the second semi-threaded rod. The splash-proof unit includes a first connecting groove and a second connecting groove formed on opposite side walls of the connecting unit, a splash-proof cover sleeved on the periphery of the connecting unit, a rectangular groove formed at the bottom of the splash-proof cover, a connecting post installed on the side wall of the rectangular groove, a receiving groove formed on the other side wall of the rectangular groove, and a locking member disposed inside the receiving groove.

[0007] Preferably, the connecting unit includes a connector disposed between the first clamp and the second clamp, and a connecting spring having one end fixedly connected to the inner wall of the first clamp and the other end fixedly connected to the inner wall of the second clamp.

[0008] Preferably, the connector includes a first connecting seat installed on the inner sidewall of the second clamp, a second connecting seat installed on the inner sidewall of the first clamp, a connecting through hole opened on the top of the second connecting seat, and a connecting rod installed on the top of the first connecting seat and passing through the connecting through hole.

[0009] Preferably, the gripping unit includes handles mounted on the bottom of the second clamp and the first clamp, and anti-slip sleeves mounted on the periphery of the handles.

[0010] Preferably, the splash guard includes a rigid base and a transparent shell mounted on top of the rigid base.

[0011] Preferably, the engaging component includes a movable through hole formed in the side wall of the receiving groove and communicating with the rectangular groove, a return spring installed on the side wall of the receiving groove, a connecting plate installed on the end of the return spring, and an engaging post installed on the side wall of the connecting plate opposite to the return spring and passing through the movable through hole.

[0012] Preferably, the splash-proof unit includes an annular ring installed on the inner sidewall of the transparent shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by incorporating an opening unit and a splash-proof unit, when the liquid inside the reagent bottle is far from the stopper and unlikely to splash, a rubber sleeve is fitted onto the circumferential surfaces of the first and second semi-threaded rods. The two semi-threaded rods with rubber sleeves are then inserted into the inner stopper. Pressing the two handles together causes the rubber sleeves to deform under force, upgrading the contact between the outer diameter of the pliers and the inner diameter of the reagent bottle stopper from a line contact to a surface contact. This increases the contact area and thus the friction between the pliers and the inner stopper. The two parts are tightly joined, preventing slippage, making opening the stopper convenient and effortless, avoiding breakage of the inner stopper due to excessive clamping force, and ensuring that the reagent does not leak. When the liquid in the reagent bottle is close to the stopper, press the connecting plate away from the rectangular groove and compress the return spring until the locking post is completely disengaged from the rectangular groove. At this point, insert the connector of the stopper pliers into the splash guard so that the connecting post connects with the first connecting groove. Then, remove the force applied to the connecting plate. Under the elastic force of the return spring, the locking post connects with the second connecting groove. When the stopper is opened again, the liquid brought out by the stopper will splash onto the inner bottom wall and inner side wall of the splash guard. Subsequently, the splashed liquid will be blocked by the annular ring as it flows down under the action of gravity, thus preventing the reagent from splashing and dripping.

The rubber sleeve 105 increases the friction between the threaded rod and the inner plug. like Figure 5 As shown, the splash guard 4 includes a first connecting groove and a second connecting groove on opposite side walls of the connecting unit 2, a splash guard 401 sleeved on the periphery of the connecting unit 2, a rectangular groove on the bottom of the splash guard 401, a connecting post 402 installed on the side wall of the rectangular groove, a receiving groove on the other side wall of the rectangular groove, and a locking member 403 disposed inside the receiving groove. The locking member 403 facilitates the connection and fixation between the splash guard 401 and the inner plug clamp body.

[0018] like Figure 2 As shown, the connecting unit 2 includes a connector 201 disposed between the first clamp 101 and the second clamp 102, and a connecting spring 202 with one end fixedly connected to the inner wall of the first clamp 101 and the other end fixedly connected to the inner wall of the second clamp 102. The connecting spring 202 facilitates the return movement between the first clamp 101 and the second clamp 102.

[0019] like Figure 1As shown, the connector 201 includes a first connecting seat 2011 installed on the inner sidewall of the second clamp 102, a second connecting seat 2012 installed on the inner sidewall of the first clamp 101, a connecting through hole opened on the top of the second connecting seat 2012, and a connecting rod 2013 installed on the top of the first connecting seat 2011 and passing through the connecting through hole. The connector 201 enables the first clamp 101 and the second clamp 102 to rotate relative to each other.

[0022] like Figure 5 As shown, the engaging component 403 includes a movable through hole formed in the side wall of the receiving groove and communicating with the rectangular groove, a return spring 4031 installed on the side wall of the receiving groove, a connecting plate 4032 installed at the end of the return spring 4031, and an engaging post 4033 installed on the side wall opposite to the return spring 4031 and passing through the movable through hole. The setting of the return spring 4031 facilitates the return movement of the engaging post 4033.

[0023] When the liquid inside the reagent bottle is far from the stopper and unlikely to splash, the rubber sleeve 105 is fitted onto the circumferential side of the first semi-threaded rod 103 and the second semi-threaded rod 104. The two semi-threaded rods with the rubber sleeve 105 are inserted into the inner stopper. Then, the two handles 301 are pressed together, causing the rubber sleeve 105 to deform under force. This changes the contact between the outer diameter of the pliers and the inner diameter of the reagent bottle stopper from line contact to surface contact, increasing the contact area and thus increasing the friction between the pliers and the inner stopper. The two are tightly joined and do not slip, making it easy and effortless to open the stopper. This avoids the inner stopper from breaking due to excessive clamping force and ensures that the reagent will not leak. Example

[0025] like Figure 2 As shown, the connecting unit 2 includes a connector 201 disposed between the first clamp 101 and the second clamp 102, and a connecting spring 202 with one end fixedly connected to the inner wall of the first clamp 101 and the other end fixedly connected to the inner wall of the second clamp 102. The connecting spring 202 facilitates the return movement between the first clamp 101 and the second clamp 102.
