Description

Technical Field

[0001] The utility model relates to the technical field of flask brushes, in particular to a flask brush with an adjustable grip length. Background Art

[0002] A flask brush is a tool specially used to clean various types of laboratory flasks, test tubes and other glassware. It can effectively remove dirt, residue and sediment from the inner wall of containers such as round-bottom flasks, thereby keeping the utensils clean and the accuracy of the experiment.

[0003] After searching, the Chinese patent "Flask Brush" authorization announcement number "CN215936574U" uses an inner rod, a sleeve rod, a first spring and a limit plate to change the state of the brush strip as the inner rod and the sleeve rod slide relative to each other and lock the adjusted brush strip state. The sliding sleeve allows the length of the brush strip to be adjusted, and the change amplitude of the brush strip can be adjusted, making the flask brush more suitable for round-bottom flasks.

[0004] In the above application, since the first spring is elastic, the position of the flask brush in the round-bottom flask needs to be adjusted back and forth to clean it, which may easily cause the inner rod to loosen on the sleeve rod, and easily affect the unstable opening of the brush strip, thereby affecting the cleaning effect of the round-bottom flask.

[0005] Therefore, a flask brush with adjustable grip length is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a flask brush with an adjustable grip length in order to solve the above problems, thereby improving the problem that the inner rod is easily loosened on the sleeve rod, thereby affecting the unstable opening of the brush strip.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions: a flask brush with an adjustable grip length, comprising: three elastic brush strips; a debugging mechanism, wherein the debugging mechanism is arranged on the surface of the elastic brush strip; wherein the debugging mechanism includes a grip tube arranged at one end of the elastic brush strip, wherein one end of the inner wall of the grip tube is threadedly connected to a screw, one end of the screw is fixedly connected to a long rod, and the other end of the surface of the long rod is fixedly connected to an annularly distributed nylon bristle, and one end of the surface of the grip tube is rotatably connected to a movable ring, one end of the elastic brush strip is fixedly connected to one end of the movable ring, and the other end of the elastic brush strip is fixedly connected to one end of the long rod. Through the screw, long rod, grip tube and movable ring, the three elastic brush strips can be opened, making the elastic brush strips stable after opening. Compared with the existing elastic brush strips used to clean round-bottom flasks, which are easily unstable after opening, this method ensures that the elastic brush strips are stable when cleaning round-bottom flasks. The nylon bristles at one end of the long rod increase the contact area between the flask brush and the bottom wall of the round-bottom flask, ensuring the cleaning effect of the round-bottom flask.

[0008] Preferably, a handle is fixedly connected to the surface of the grip tube, and an anti-slip pad is fixedly connected to the surface of the handle. The handle and the anti-slip pad facilitate better gripping of the grip tube and better adjustment of the specific position of the screw in the grip tube.

[0009] Preferably, one end of the screw is fixedly connected to an elastic sleeve, another end of which is fixedly connected to a mounting ring, the surface of which is rotatably connected to one end of the grip tube. The mounting ring and the elastic sleeve provide a sealed and protective seal on the exposed screw, preventing cleaning fluid from adhering to the screw surface and ensuring the service life of the screw.

[0010] Preferably, a sealing ring is embedded in one end of the grip tube, and the surface of the long rod contacts the inner side of the sealing ring. The sealing ring seals the connection between the long rod surface and the inner wall of the grip tube, preventing cleaning liquid from seeping into the grip tube and ensuring the cleanliness of the grip tube.

[0011] Preferably, a slip ring is fixedly connected to the surface of the long rod.

[0012] Preferably, two retaining rings are fixedly connected to the inner wall of the grip tube, and one end of the surface of the long rod passes through and extends out of the inner side of the retaining ring. The sliding ring and the retaining ring limit the movement range of the long rod, preventing the screw from separating from the inner wall of the grip tube when it rotates and moves within the grip tube.

[0013] Preferably, the sealing ring and the elastic sleeve are both silicone components.

[0014] The beneficial effects of the utility model are:

[0015] 1. The three elastic brush strips are opened through the screw, long rod, handle and movable ring, making the elastic brush strips stable after opening. Compared with the existing elastic brush strips used to clean round-bottom flasks, which are prone to instability after opening, this method ensures that the elastic brush strips are stable when cleaning round-bottom flasks. The nylon bristles at one end of the long rod surface increase the contact area between the flask brush and the bottom wall of the round-bottom flask, ensuring the cleaning effect of the round-bottom flask.

[0016] 2. The handle and anti-slip pad make it easier to hold the barrel and adjust the specific position of the screw in the barrel. The mounting ring and elastic sleeve can seal and protect the exposed screw, preventing the cleaning liquid from adhering to the surface of the screw and ensuring the service life of the screw.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, a flask brush with an adjustable grip length comprises: three elastic brush strips 1; a debugging mechanism 2, which is disposed on the surface of the elastic brush strips 1. The debugging mechanism 2 includes a grip tube 21 disposed at one end of the elastic brush strip 1. A screw 22 is threadedly connected to one end of the inner wall of the grip tube 21. A long rod 211 is fixedly connected to one end of the screw 22. The other end of the surface of the long rod 211 is fixedly connected to an annular arrangement of nylon bristles. A movable ring 23 is rotatably connected to one end of the surface of the grip tube 21. One end of the elastic brush strip 1 is fixedly connected to one end of the movable ring 23, and the other end of the elastic brush strip 1 is fixedly connected to one end of the long rod 211. The surface of the elastic brush strip 1 is fixedly connected to nylon bristles distributed in equal rows.

[0024] When the round-bottom flask needs to be cleaned, a certain amount of cleaning liquid is poured into the round-bottom flask, and after the grip tube 21 is inserted into the appropriate position in the round-bottom flask, one end of the surface of the grip tube 21 is held and the screw 22 is rotated. The screw 22 moves while rotating in the grip tube 21 and drives the long rod 211 to move while rotating. The rotation of the long rod 211 drives the three elastic brush strips 1 to rotate and move toward the direction close to the movable ring 23, so that the three elastic brush strips 1 are squeezed and deformed at the same time. After the three elastic brush strips 1 are opened to the appropriate state, the screw 22 is stopped to increase the holding range of the flask brush. At this time, the user holds the screw 22 and loosens the grip tube 21, so that the elastic brush strip 1 and the nylon bristles on the long rod 211 clean the inner wall of the round-bottom flask back and forth. After cleaning for a period of time, the cleaning liquid in the round-bottom flask is poured out and new cleaning liquid is poured in for rinsing.

[0025] like Figure 4 As shown, a handle 24 is fixedly connected to the surface of the grip tube 21 , and an anti-slip pad 25 is fixedly connected to the surface of the handle 24 .

[0026] When the flask brush needs to be taken out from the round-bottom flask after cleaning, hold the anti-slip pad 25 and rotate the screw 22. The screw 22 moves while rotating on one end of the inner wall of the grip tube 21. The screw 22 that moves while rotating drives the three elastic brush strips 1 to extend simultaneously through the long rod 211. After the three elastic brush strips 1 are contracted to an appropriate degree, pull the screw 22 to move the elastic brush strips 1 away from the round-bottom flask and disinfect and clean the elastic brush strips 1 for next use.

[0027] like Figure 4 As shown, one end of the screw rod 22 is fixedly connected to an elastic sleeve 27, and one end of the elastic sleeve 27 is fixedly connected to a mounting ring 28. The surface of the mounting ring 28 is rotatably connected to one end of the grip tube 21. When the screw rod 22 moves during rotation, it stretches or squeezes the elastic sleeve 27, sealing and protecting the exposed screw rod 22.

[0028] like Figure 3 As shown, a sealing ring 29 is embedded in one end of the handle 21, and the surface of the long rod 211 contacts the inner side of the sealing ring 29. The sealing ring 29 and the elastic sleeve 27 are both silicone components. The handle 21 and the long rod 211 are both polyester components.

[0029] like Figure 3 As shown, a slip ring 210 is fixedly connected to the surface of a long rod 211, and two retaining rings 26 are fixedly connected to the inner wall of the handle 21. One end of the surface of the long rod 211 passes through and extends out of the inner side of the retaining ring 26. The rotation of the long rod 211 drives the rotation of the slip ring 210. The two retaining rings 26 limit the movement of the slip ring 210 and prevent the screw 22 from disengaging from one end of the inner wall of the handle 21.

[0030] When the utility model is in use, a certain amount of cleaning liquid is poured into the round-bottom flask, and after the grip tube 21 is inserted into the appropriate position in the round-bottom flask, the anti-slip pad 25 is held and the screw 22 is rotated. The screw 22 moves while rotating in the grip tube 21 and drives the long rod 211 to move while rotating. The long rod 211 drives the three elastic brush strips 1 to rotate and move toward the direction close to the movable ring 23, so that the three elastic brush strips 1 are squeezed and deformed at the same time. After the three elastic brush strips 1 are opened to the appropriate state, the screw 22 is stopped to increase the holding range of the flask brush. At this time, the user holds the screw 22 and loosens the anti-slip pad 25, so that the elastic brush strip 1 and the nylon bristles on the long rod 211 clean the inner wall of the round-bottom flask.

[0031] It should be noted that the elastic brush strips 1 and the like in the above description are all relatively mature devices in existing technology. The specific models can be selected according to actual needs and will not be described in detail here.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
