Description

Technical Field

[0001] This utility model relates to the field of dispensing needle technology, specifically to a sealing device for a non-polluting ointment dispensing needle. Background Technology

[0002] In modern industrial production, especially in fields such as electronics, medical, and optics, precision dispensing technology plays a crucial role. The dispensing needle is one of the core components of dispensing equipment. The plaster dispensing needle is a core tool specifically designed to control the application of adhesive in the plaster production process, and its design must be adapted to the characteristics of the plaster's adhesive and the precision requirements of production. However, when transporting dispensing needles, because the needles are precision tools, if they are directly exposed to the transportation environment, they may be contaminated by dust, moisture, or deformed.

[0003] Medical instruments typically use sealed packaging boxes to effectively isolate them from the external environment and ensure product cleanliness. When transporting dispensing needles, batches of needles can be stored in sealed packaging boxes to protect them. These boxes can be made of pressure-resistant and antibacterial materials. Currently, there is a need for a contamination-proof sealing device for ointment dispensing needles.

[0004] According to the patent search, application number CN200910127182.8 describes a dispensing needle structure. The extension not only increases the surface area of ​​the dispensing needle structure to slow down the downward flow rate of the adhesive, but also provides resistance to slow down the flow rate of the adhesive, thereby achieving control over the amount of adhesive during dispensing.

[0005] The device described in the above patent has shortcomings in use: the traditional dispensing needle has a simple structure and function, lacks a sealing and protective component on the outer periphery, and the dispensing needle is exposed to the external environment for a long time. Not only is the needle easy to be contaminated, but it is also easily damaged when subjected to external impact, which reduces the service life of the device.

[0006] To address the aforementioned problems, a contamination-preventing sealing device for ointment dispensing needles is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a pollution-proof sealing device for plaster dispensing needles. By using this device, the problems mentioned in the background art are solved: the traditional dispensing needles have simple structures and functions, lack sealing and protective components on the outer periphery, and are easily contaminated when exposed to the external environment for a long time. Furthermore, the dispensing needles are easily damaged by external impacts, thus reducing the service life of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pollution-proof plaster dispensing needle sealing device, comprising a needle assembly, the needle assembly including a dispensing needle body, a protective sealing cap being snapped onto one side of the dispensing needle body; the protective sealing cap being a component made of antibacterial material; the sealing device further includes a sealing box, a box cover being snapped onto the top of the sealing box, an insert rod being fixedly connected to the bottom of the box cover, four sets of insert rods being provided, a connecting block being hinged to the front side of the box cover, a slot being provided on one side of the connecting block, the slot penetrating the left and right sides of the connecting block, an insertion cavity being provided at the top of the sealing box, four sets of insertion cavities being provided, the insert rods matching the insertion cavities, a rotating rod being rotatably connected to one side of the sealing box, a rotating plate being fixedly connected to one end of the rotating rod, the rotating plate matching the fixed plate; a rotating disk being rotatably connected to the outside of the sealing box, a limiting cavity being provided on the side wall of the sealing box, two sets of limiting cavities being provided, a movable sealing plate being slidably connected between the two sets of limiting cavities.

[0009] Preferably, a sealing block is fixedly connected to the front side of the movable sealing plate, and an installation slot block is fixedly connected to the side wall of the sealing box, wherein the sealing block and the installation slot block are mutually matched.

[0010] Preferably, a threaded rod is rotatably connected inside the sealing box, and one end of the threaded rod is fixedly connected to the rotating disk.

[0011] Preferably, the movable sealing plate is threaded to the outer periphery of the threaded rod, and a handle block component is provided on the top of the box cover.

[0012] Preferably, a mounting base is fixedly connected to the bottom of the inner cavity of the sealing box, and a positioning support plate is provided above the mounting base.

[0013] Preferably, mounting plates are provided on both sides of the positioning support plate, and the positioning support plate is fixedly connected to the inside of the sealing box through the mounting plates. Insertion cavities are evenly distributed on one side of the positioning support plate, and multiple sets of insertion cavities are provided. The insertion cavities are matched with the needle assembly.

[0014] Preferably, the needle assembly extends through the insertion cavity to one side of the mounting base, and both the sealing box and the box cover are components made of antibacterial material.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] When the dispensing needle body is not in use, the matching protective sealing cap can be snapped onto the end of the dispensing needle body, sealing and protecting the needle inside the protective sealing cap. This protects the needle from contamination when not in use, extends the lifespan of the dispensing needle, and reduces the frequency and cost of needle replacement. When carrying or transporting sealed boxes in bulk, the needles, being precision tools, are susceptible to contamination or deformation from dust and moisture. This application allows for the storage of bulk needle assemblies in sealed boxes. The sealed box and its lid are made of antibacterial material. The sealed needle assembly is inserted into the insertion cavity, ensuring the needle assembly... The bottom of the component rests on the top of the mounting base, which supports the needle assembly. The insertion cavity limits the needle assembly, and each set of insertion cavities can be used to install one set of needle assemblies. After multiple sets of needle assemblies have been installed inside the sealing box, the rotating disk is rotated in the opposite direction. The rotating disk drives the threaded rod to rotate in the opposite direction, and the threaded rod drives the movable sealing plate to move towards the mounting slot block. The movable sealing plate drives the sealing block to move towards the mounting slot block until the sealing block is inserted into the mounting slot block. The sealing block and the mounting slot block are locked together. The mounting slot block, the movable sealing plate, and the fixing plate are used to seal the opening of the sealing box, thereby sealing and storing a batch of needle assemblies and improving the protective performance of the needle assemblies.

[0017] After the top opening of the sealing box is closed, to further improve the sealing performance, move the lid to one side of the sealing box, simultaneously aligning multiple sets of insert rods with multiple sets of insertion holes, and simultaneously lifting one side of the connecting block to insert the insert rods into the insertion holes. Close the lid on top of the sealing box, then release the connecting block to allow it to hang naturally. At this point, the rotating plate will pass through the slot, and the rotating plate will be horizontally positioned in front of the slot, as shown in the attached diagram. Figure 2 The operator then rotates the rotating plate ninety degrees, positioning it vertically in front of the empty slot. The rotating plate acts as a blocking and limiting element in the empty slot, as shown in the attached diagram. Figure 1 This completes the fixed installation between the sealing box and the box cover. The operator can carry the sealing device and transport multiple sets of needle components. The sealing device protects the dispensing needle body and prevents the dispensing needle body from being contaminated.

[0018] When the needle assembly needs to be removed, first rotate the rotating plate 90 degrees to change it from a vertical to a horizontal position, aligning the rotating plate with the empty slot. The user then lifts the side of the connecting block, causing it to move to the front of the rotating plate. At this point, the connecting block is no longer fixed by the rotating plate. Pull the cover away from the sealing box, and multiple sets of inserts will simultaneously be pulled out from multiple sets of insertion cavities, thus separating the cover from the sealing box. Reverse the rotating disc, causing the threaded rod to rotate in the opposite direction, which in turn moves the moving sealing plate away from the mounting slot block. The sealing block is then pulled out from inside the mounting slot block until the moving sealing plate retracts below the fixed plate. At this point, the sealing box opening is opened, and each needle assembly is pulled away from the insertion cavity, thus removing the needle assembly from the sealing box. This design facilitates the operator in removing the needle assembly from the sealing device. When the dispensing needle body needs to be used, simply pull the protective sealing cap off the front end of the dispensing needle body to use it. Attached Figure Description

Four sets of insert rods 21 are provided. A connecting block 22 is hinged to the front side of the box cover 2. A slot 23 is provided on one side of the connecting block 22, and the slot 23 penetrates through it. On the left and right sides of the connecting block 22, the top of the sealing box 1 is provided with a socket cavity 11, which has four sets. The plug rod 21 is matched with the socket cavity 11. A rotating rod 14 is rotatably connected to one side of the sealing box 1. A rotating plate 15 is fixedly connected to one end of the rotating rod 14. The rotating plate 15 is matched with the fixed plate 13. A rotating disk 12 is rotatably connected to the outside of the sealing box 1. A limiting cavity 111 is provided on the side wall of the sealing box 1. Two sets of limiting cavities 111 are provided. A movable sealing plate 122 is slidably connected between the two sets of limiting cavities 111.

[0029] The present invention will be further described below with reference to the embodiments. Example

[0030] This application discloses the following technical solutions, specifically as follows: Figures 1-6As shown, a sealing block 123 is fixedly connected to the front side of the movable sealing plate 122, and an installation slot block 16 is fixedly connected to the side wall of the sealing box 1. The sealing block 123 and the installation slot block 16 are matched with each other. A threaded rod 121 is rotatably connected inside the sealing box 1. One end of the threaded rod 121 is fixedly connected to the rotating disk 12. The movable sealing plate 122 is threadedly connected to the outer periphery of the threaded rod 121. A handle block component is provided on the top of the box cover 2. An installation seat 18 is fixedly connected to the bottom of the inner cavity of the sealing box 1. A positioning support plate 17 is provided above the installation seat 18. Installation plates are provided on both sides of the positioning support plate 17. The positioning support plate 17 is fixedly connected to the inside of the sealing box 1 through the installation plates. Insertion cavities 171 are evenly distributed on one side of the positioning support plate 17. Multiple sets of insertion cavities 171 are provided. The insertion cavities 171 are matched with the needle assembly 3. The needle assembly 3 extends through the insertion cavity 171 to one side of the installation seat 18. Both the sealing box 1 and the box cover 2 are components made of antibacterial material.

[0031] In summary, the working principle is as follows: When the dispensing needle body 31 is not in use, the matching protective sealing cover 32 can be snapped and fixed to the end of the dispensing needle body 31, sealing and protecting the needle inside the protective sealing cover 32. This protects the needle from contamination when not in use, and the protective sealing cover 32 can protect the needle and extend the service life of the dispensing needle. The sealing treatment can extend the service life of the dispensing needle and reduce the number of times and costs of replacing the dispensing needle. When carrying the sealing box 1 or transporting a batch of sealing boxes 1, since the needle is a precision tool, it may be contaminated or deformed by dust, moisture, etc. This application can store a batch of needle assemblies 3 in the sealing box 1. The sealing box 1 and the box cover 2 are made of antibacterial material. The covered needle assembly 3 is inserted into the insertion cavity 171, and the bottom end of the needle assembly 3 rests on the top of the mounting base 18. The mounting base 18 provides support for the needle assembly 3, and the insertion cavity 171 limits the needle assembly 3. Each insertion cavity 171 can be used to install one set of needle assemblies 3. After multiple sets of needle assemblies 3 have been installed inside the sealing box 1, the rotating disk 12 is rotated in the opposite direction. The rotating disk 12 drives the threaded rod 121 to rotate in the opposite direction. The threaded rod 121 drives the movable sealing plate 122 to move towards the mounting slot block 16. The movable sealing plate 122 drives the sealing block 123 to move towards the mounting slot block 16 until the sealing block 123 is inserted into the mounting slot block 16. The sealing block 123 and the mounting slot block 16 are locked together. The mounting slot block 16, the movable sealing plate 122 and the fixing plate 13 are used to seal the opening of the sealing box 1, thereby sealing and storing a batch of needle assemblies 3 and improving the protective performance of the needle assemblies 3.

[0032] After the top opening of the sealing box 1 is closed, to further improve the sealing performance of the sealing box 1, the box cover 2 is moved to one side of the sealing box 1. At the same time, multiple sets of insert rods 21 are respectively aligned with multiple sets of insertion holes 11. Simultaneously, one side of the connecting block 22 is lifted upwards, and the insert rods 21 are inserted into the insertion holes 11. The box cover 2 is then closed on the top of the sealing box 1. Then the connecting block 22 is released, allowing it to hang down naturally. At this time, the rotating plate 15 will pass through the slot 23. The rotating plate 15 is in a horizontal position in front of the slot 23, as shown in the attached figure. Figure 2 The operator then rotates the rotating plate 15, causing it to rotate 90 degrees, so that the rotating plate 15 is in a vertical position in front of the empty slot 23. The rotating plate 15 acts as a blocking and limiting mechanism for the empty slot 23, as shown in the attached diagram. Figure 1 This completes the fixed installation between the sealing box 1 and the box cover 2. The operator can carry the sealing device and transport multiple sets of needle components 3. The sealing device protects the dispensing needle body 31 and prevents the dispensing needle body 31 from being contaminated.

[0033] When the needle assembly 3 needs to be removed, first rotate the rotating plate 15 90 degrees to change it from a vertical to a horizontal position, aligning the rotating plate 15 with the empty slot 23. The user then lifts the side of the connecting block 22, causing it to move to the front of the rotating plate 15. At this point, the connecting block 22 is no longer limited and fixed by the rotating plate 15. Pull the cover 2 away from the sealing box 1, and multiple sets of insertion rods 21 are simultaneously pulled out from multiple sets of insertion cavity 11, thus separating the cover 2 from the sealing box 1. Rotate the rotating disk 12 in the opposite direction, causing the threaded rod 121 to rotate in the opposite direction, thereby moving the sealing box. The sealing plate 122 moves away from the mounting slot block 16, and the sealing block 123 is pulled out from inside the mounting slot block 16 until the moving sealing plate 122 retracts to below the fixing plate 13. At this time, the opening of the sealing box 1 is opened, and each set of needle assembly 3 is pulled away from the insertion cavity 171, thereby removing the needle assembly 3 from the sealing box 1. This design makes it easy for the operator to remove the needle assembly 3 from the sealing device. When the dispensing needle body 31 needs to be used, the protective sealing cover 32 can be directly pulled off from the front end of the dispensing needle body 31, and the dispensing needle body 31 can be used.
