Description

Technical Field

[0001] This utility model relates to the field of anti-loosening clips, specifically an anti-loosening clip for a glass tube syringe. Background Technology

[0002] In the field of medical devices, an infusion pump is a medical device mainly used to control and monitor the injection speed and dosage of liquid drugs. The glass tube syringe is a key component for storing and measuring drugs, so the anti-loosening of the glass tube is crucial to ensure accurate drug delivery.

[0003] Currently, there is no mature solution for the problem of preventing loosening of glass tubes on the market. Many customers choose to apply glue to the threads themselves, which is troublesome to install and disassemble, and glue residue is easy to remain on the valve head. Some customers choose to machine parts and screw them onto the back plate, but machining is costly, inconvenient to install and disassemble, and metal parts can easily damage the glass tube during installation. Therefore, we have proposed a glass tube injector anti-loosening clip. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a glass tube syringe anti-loosening clip, including a back plate, on which a glass tube syringe is movably mounted, and an anti-loosening clip. The glass tube syringe is provided with a threaded part, and the anti-loosening clip is located on the side of the threaded part and is movably mounted on the back plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 This utility model provides a technical solution: a glass tube syringe anti-loosening clip, including a back plate 1, a glass tube syringe 2 movably mounted on the back plate 1, and an anti-loosening clip 4. The glass tube syringe 2 is provided with a threaded part 3, and the anti-loosening clip 4 is located on the side of the threaded part 3 and is movably mounted on the back plate 1.

[0025] Furthermore, the anti-loosening clip 4 includes a fixing member 401, a base 402, a mounting bracket 410, and a connecting bracket 411. The connecting bracket 411 is fixedly connected to the back of the back plate 1, and the mounting bracket 410 is slidably connected to the connecting bracket 411. The anti-loosening clip 4 also includes an adjustment groove 409, which is opened on the back plate 1, and the mounting bracket 410 is movably installed in the adjustment groove 409. The anti-loosening clip 4 also includes a screw 412 and a limiting head 413. The back plate 1 and the connecting bracket 411 have sliding holes corresponding to the position of the screw 412, and the mounting bracket 410 has screw holes corresponding to the position of the screw 412. The screw 412 is movably installed on the back plate 1, the mounting bracket 410, and the connecting bracket 411. The limiting head 413 is fixedly connected to one end of the screw 412 and is located on the side of the connecting bracket 411.

[0026] The mounting bracket 410 is movably installed in the adjustment groove 409 on one side. When the screw 412 rotates in the screw hole on the mounting bracket 410, the mounting bracket 410 can only move up and down along the connecting bracket 411 because the other side of the mounting bracket 410 is slidably connected to the connecting bracket 411. As the screw 412 rotates, the mounting bracket 410 can be adjusted up and down on the connecting bracket 411, making it easy to adjust the height of one side of the mounting bracket 410. The fixing member 401 is fixedly connected to the mounting bracket 410, making it easy to adjust the height of the fixing member 401.

[0027] Furthermore, the anti-loosening clip 4 also includes a knob 414, a mounting groove 415, a washer 416, and an elastic washer 417. The knob 414 is fixedly connected to the other end of the screw 412 and is located on the side of the back plate 1. The mounting groove 415 is opened on the knob 414. The washer 416 and the elastic washer 417 are movably mounted on the screw 412 and are located in the mounting groove 415. One side of the washer 416 is slidably connected to the elastic washer 417, and the other side of the washer 416 is slidably connected to the bottom wall of the mounting groove 415.

[0028] The knob 414 is provided with an elastic washer 417, which pushes the knob 414 outward. The limiting head 413 and the side of the connecting bracket 411 fit tightly against each other. When the screw 412 rotates, it is not easy for the knob to move or vibrate back and forth. The side of the elastic washer 417 slides against the inner wall of the mounting groove 415 through the washer 416, thereby replacing the direct contact between the elastic washer 417 and the mounting groove 415, reducing the friction when the knob 414 rotates, and making the knob 414 easier to rotate.

[0029] Example 2:

[0030] Please see Figures 1-4 Based on embodiment 1, this utility model provides another technical solution: the base 402 is fixedly connected to the mounting bracket 410, the fixing member 401 is snapped to the base 402, and the fixing member 401 is movably installed with the threaded part 3. The anti-loosening clip 4 also includes a limiting groove 403 and a sliding column 404. The limiting groove 403 is opened on the fixing member 401, and the sliding column 404 is fixedly connected to the base 402, and the sliding column 404 is movably connected in the limiting groove 403.

[0031] The sliding column 404 is directly inserted into the fixing member 401, making the fixing member 401 easy to install. Pressing the upper end of the sliding column 404 pushes the fixing member 401 upwards, making it easy to separate the fixing member 401 from the sliding column 404. This facilitates the installation and removal of the fixing member 401. When dealing with different glass tube syringes 2, different fixing members 401 can be used to adapt to different glass tube syringes 2. Furthermore, the height of the fixing member 401 can be finely adjusted by rotating the knob 414, improving the applicability of the anti-loosening clip 4.

[0032] Furthermore, the anti-loosening clip 4 also includes a positioning post 407 and a spring 408. The positioning post 407 is fixedly connected to the middle position of the base 402. A storage groove is provided in the middle of the fixing part 401. One end of the spring 408 is fitted with the positioning post 407, and the other end of the spring 408 is movably installed in the storage groove of the fixing part 401.

[0033] One end of the spring 408 encloses the positioning post 407 in its internal position, and the other end of the spring 408 extends into the storage groove of the fixing member 401, so that the position of the spring 408 is fixed and it is not easy to fall off.

[0034] Furthermore, the anti-loosening clip 4 also includes a fastener 405 and a slot 406. The slot 406 is opened on both sides of the base 402, and the fastener 405 is movably connected to both sides of the fixing member 401. The fastener 405 and the slot 406 are movably installed.

[0035] The fastener 405 and the slot 406 are installed together, making it easy to install the fixing part 401. When it is necessary to disassemble, the fastener 405 can be pried to the side with one hand to separate the fixing part 401 from the base 402, making disassembly more convenient.

[0036] After the threaded part 3 of the glass tube syringe 2 is engaged with the fixing part 401, the fixing part 401 is pushed inward, which compresses the spring 408. The fastener 405 engages with the slot 406 of the base 402, locking the fixing part 401 and the base 402 together. The toothed structure of the fixing part 401 and the threaded part 3 makes the glass tube syringe 2 less prone to loosening. When disassembling, the fastener 405 on the side is pinched outward with one hand, which releases the connection between the fastener 405 and the slot 406, resets the spring 408, and resets the fixing part 401 upward, making the fixing part 401 easy to unlock.
