Description

Technical Field

[0001] The present application relates to the technical field of denture processing, and in particular to a glue gun for fixing denture models. Background Art

[0002] Dentures are commonly referred to as "false teeth." In medicine, they are a general term for restorations made after partial or complete tooth loss in the upper or lower jaw. Dentures are categorized as removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be removed and put on by the patient, while removable dentures (commonly known as "removable dentures") can be easily removed and put on by the patient. During the production of dentures, a model is created, and a corresponding mold is produced. The denture model is then bonded and fixed using a hot melt glue gun.

[0003] A hot melt glue gun is a bonding tool that heats a glue stick or other adhesive material and squeezes the heated glue liquid through a metal nozzle. The extruded glue liquid is then used to bond objects. Typical hot melt glue guns can withstand prolonged use at temperatures of 300°C without deforming, and their nozzles are durable.

[0004] However, after the power is turned off, high temperature often remains in the metal nozzle of a traditional hot melt glue gun. When the operator puts the hot melt glue gun away after use, his hand may accidentally touch the metal nozzle and get burned. In addition, the remaining glue in the metal nozzle still has a certain temperature and is prone to flow out of the nozzle naturally under gravity and stick to other surrounding objects. After the flowed glue solidifies, it is inconvenient to clean it up, which also increases the waste of glue. There is room for improvement. Utility Model Content

[0005] In order to solve the above problems, the present application provides a glue gun for fixing denture models.

[0006] The present application provides a glue gun for fixing denture models using the following technical solutions:

[0007] A glue gun for fixing a denture model, comprising a hot melt gun, a nozzle mounted at one end of the hot melt gun for bonding and fixing the denture model, and a protective mechanism mounted at one end of the hot melt gun for protecting the nozzle, the protective mechanism comprising a slip ring slidably mounted on the outer wall of one end of the hot melt gun, and a protective sleeve fixedly mounted on one side of the slip ring for covering the nozzle;

[0008] The glue outlet end of the nozzle is fitted with a cover plate, and a connecting piece is provided on the top of the cover plate. The connecting piece includes a second rotating rod fixed on the top of the cover plate and rotatably connected to the protective sleeve, and an extension sleeve rod slidably arranged on the outer wall of the top end of the second rotating rod. A push plate for pushing is fixed on the top of the extension sleeve rod on the side facing away from the nozzle.

[0009] By adopting the above technical solution, the protective sleeve can cover the nozzle, so that the operator's hand will not directly touch the nozzle and get burned when the hot melt glue gun is powered off and placed, thereby improving the safety performance of the glue gun. The cover plate can seal the glue outlet of the nozzle after the hot melt gun is powered off, so that the residual glue in the nozzle will not flow out naturally and be wasted.

[0010] Preferably, a fixing plate is fixedly provided on the top of the hot melt gun, and a return spring for pushing the slip ring toward the nozzle is fixedly provided on one side of the fixing plate.

[0011] By adopting the above technical solution, the protective sleeve can be continuously sleeved on the outside of the nozzle through the elastic force of the reset spring and the limitation of the slip ring, thereby continuously protecting the nozzle.

[0012] Preferably, a hanging ring is fixedly provided on the top of the side of the slip ring facing away from the protective sleeve, and the hanging ring is located above the reset spring. The top of the fixed plate is rotatably connected to a hook rod for hanging the hanging ring to fix the slip ring when the protective sleeve is pulled away from the nozzle. A limit plate is fixedly provided on one side of the fixed plate to cooperate with and abut against the bottom of the hook rod.

[0013] By adopting the above technical solution, when the denture model needs to be bonded and fixed using a hot melt glue gun, the protective sleeve can be slid away from the nozzle, and the hook rod can be used to hang the hanging ring to fix the sliding protective sleeve and other components.

[0014] Preferably, a notch is provided at the top of one end of the protective sleeve for the second rotating rod to pass through, a first rotating rod is rotatably connected in the notch of the protective sleeve, the second rotating rod is fixedly connected to the outer wall of the first rotating rod, and observation holes are provided at both ends of the protective sleeve for the operator to observe the nozzle and the cover plate.

[0015] By adopting the above technical solution, after the operator pushes the push plate, the cover plate can be pulled away from the nozzle by rotating the connecting piece, which facilitates the use of the hot melt gun, and the top of the connecting piece can be extended by sliding the extension sleeve.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The protective sleeve can cover the nozzle, so that when the hot melt glue gun is powered off and placed, the operator's hand will not directly touch the nozzle and get burned, thereby improving the safety performance of the glue gun. The cover plate can seal the glue outlet of the nozzle after the hot melt gun is powered off, so that the residual glue in the nozzle will not flow out naturally and be wasted. After the operator pushes the push plate, the cover plate can be pulled away from the nozzle through the rotating connector, which is convenient for the use of the hot melt gun. The top of the connector can be extended by sliding the extension sleeve. Under the lever theorem, the operator can push the push plate more labor-saving. After the connector is shortened, the overall volume of the glue gun can be reduced, which is convenient for transportation.

[0018] 2. Through the elastic force of the return spring and the limit of the sliding ring, the protective sleeve can be continuously put on the outside of the nozzle, thereby continuously protecting the nozzle. When the denture model needs to be bonded and fixed with a hot melt glue gun, the protective sleeve can be slid away from the nozzle, and the hook rod can be used to hang the hanging ring to fix the protective sleeve and other components after sliding, which is convenient for operation.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0025] The embodiment of the present application discloses a glue gun for fixing a denture model.

[0026] A glue gun for fixing denture models, referring to Figure 1-2 , including a hot melt gun 1, a nozzle 11 and a protective mechanism. The hot melt gun 1 can heat glue sticks and other glue materials, and extrude the heated glue through the metal nozzle 11. The extruded glue can bond and fix the denture model. The hot melt gun 1 and the nozzle 11 constitute the existing hot melt glue gun, and its internal structure and principle have been disclosed, so I will not elaborate on them here.

[0027] Reference Figure 1-2 The protective mechanism includes a slip ring 2 that is slidably arranged on the outer wall of one end of the corresponding hot melt gun 1, and a protective sleeve 21 that is fixed on one side of the slip ring 2 and is used to cover the nozzle 11. The slip ring 2 can connect the hot melt gun 1 and the protective sleeve 21, so that the protective sleeve 21 can slide horizontally on the hot melt gun 1.

[0028] Reference Figure 1-2 A fixing plate 3 is fixed on the top of the hot melt gun 1, and a return spring 31 for pushing the slip ring 2 toward the nozzle 11 is fixed on one side of the fixing plate 3. One end of the return spring 31 is fixedly connected to the slip ring 2. The fixing plate 3 can connect the hot melt gun 1 and the return spring 31. Under the elastic force of the return spring 31, the protective sleeve 21 will continue to be sheathed on the outside of the nozzle 11, thereby continuously protecting the nozzle 11.

[0029] Reference Figure 1-2 A hanging ring 32 is fixed on the top of the side of the slip ring 2 facing away from the protective sleeve 21. The hanging ring 32 is located above the return spring 31. The top of the fixed plate 3 is rotatably connected to a hook rod 33 for hanging the hanging ring 32 to fix the slip ring 2 when the protective sleeve 21 is pulled away from the nozzle 11. The hook rod 33 consists of a hook that cooperates with the hanging ring 32 and a long rod rotatably connected to the top of the fixed plate 3. When it is necessary to use a hot melt glue gun to bond and fix the denture model, the protective sleeve 21 can be slid toward the side of the fixed plate 3, so that the protective sleeve 21 is separated from the nozzle 11, and then the hook of the hook rod 33 is used to hang the hanging ring 32 to fix the protective sleeve 21 and other components after sliding. The nozzle 11 that is separated from the protective sleeve 21 can be used normally to bond the denture model.

[0030] Reference Figure 1-2 A limit plate 34 is fixedly provided on one side of the fixing plate 3, which is in contact with the bottom of the hook rod 33. The limit plate 34 can support and limit the hook rod 33 to limit the rotation angle and range of the hook rod 33, so that the hook rod 33 will not droop naturally and touch the return spring 31 at the bottom, thereby hindering the expansion and contraction process of the return spring 31.

[0031] Reference Figure 1-2 The glue outlet end of the nozzle 11 is fitted with a cover plate 4, which can seal the glue outlet of the nozzle 11 after the hot melt gun 1 is powered off, so that the residual glue in the nozzle 11 will not flow out naturally, reducing the cleaning intensity of the glue gun in the later stage and reducing the waste of glue.

[0032] Reference Figure 2-4A connecting piece is provided at the top of the cover plate 4, which includes a second rotating rod 41 fixedly arranged on the top of the cover plate 4 and rotatably connected to the protective sleeve 21, and an extension sleeve rod 42 slidably arranged on the outer wall of the top end of the second rotating rod 41. A push plate 43 for pushing is fixedly provided on the top of the extension sleeve rod 42 on the side facing away from the nozzle 11. A notch 22 is provided at the top of one end of the protective sleeve 21 for the second rotating rod 41 to pass through. The first rotating rod 23 is rotatably connected in the notch 22 of the protective sleeve 21. The second rotating rod 41 is fixedly connected to the outer wall of the first rotating rod 23. The notch 22 can provide space for the second rotating rod 41 to rotate. The first rotating rod 23 can connect the protective sleeve 21 with the second rotating rod 41, and the extension sleeve rod 42 can support and fix the push plate 43.

[0033] The operator can push the push plate 43 to drive the connecting piece composed of the second rotating rod 41 and the extension sleeve rod 42 to rotate. After the rotation, the bottom end of the connecting piece can pull the cover plate 4 away from the nozzle 11, so that the nozzle 11 can discharge glue smoothly, which is convenient for bonding the denture model. The operator can slide the extension sleeve rod 42 upward to extend the top of the connecting piece. Since the top end of the connecting piece is long and the bottom end is short, according to the lever theorem, it is more labor-saving for the operator to push the push plate 43. After the connecting piece is shortened, the overall volume of the glue gun can be reduced, which is convenient for transportation.

[0034] Reference Figure 1-3 Observation holes 24 are provided at both ends of the protective sleeve 21 for the operator to observe the nozzle 11 and the cover plate 4. The operator can observe the nozzle 11 and the cover plate 4 in the protective sleeve 21 through the observation holes 24 and can intuitively understand the status of the nozzle 11 and the cover plate 4.

[0035] The implementation principle of a glue gun for fixing a denture model in the embodiment of the present application is as follows:

[0036] When in use, the hot melt gun 1 is preheated to melt the remaining glue in the nozzle 11. Then, the operator pushes the push plate 43 to rotate the connecting member composed of the second rotating rod 41 and the extension sleeve rod 42. After the rotation, the bottom end of the connecting member can pull the cover plate 4 away from the nozzle 11.

[0037] Then, the protective sleeve 21 is slid toward the fixing plate 3 so that the protective sleeve 21 is separated from the nozzle 11. Then, the hook rod 33 is used to hook the hanging ring 32 to fix the sliding protective sleeve 21 and other components. Then, the hot melt gun 1 can extrude the heated glue through the nozzle 11, and the extruded glue can be used to bond and fix the denture model.

[0038] After the denture model is bonded, the hot melt gun 1 is powered off and the hook rod 33 is removed from the hanging ring 32. At this time, the protective sleeve 21 and other components will slide toward the nozzle 11 under the elastic force of the return spring 31, so that the protective sleeve 21 can cover the nozzle 11, thereby preventing the operator's hand from touching the nozzle 11 and being burned when the hot melt glue gun is powered off and placed, thereby improving the safety performance of the glue gun;

[0039] At the same time, by rotating the connector in the opposite direction, the cover plate 4 can be used to seal the glue outlet of the nozzle 11, so that the glue remaining in the nozzle 11 will not flow out naturally and be wasted, which is energy-saving and environmentally friendly.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
