Description

Technical Field

[0001] This application relates to the field of tape applicator technology, and in particular to a tape applicator that can be quickly disassembled. Background Technology

[0002] Various types of protective tapes and masking tapes are widely used in building decoration, interior construction, and tile and skirting board installation to cover and protect completed walls, doors, windows, glass and other components, preventing them from being contaminated by paint, varnish or mortar during subsequent construction.

[0003] Existing tape applicators only have basic tape unfolding and cutting functions. Users need to press the tape onto the floor or tiles while unfolding it, making operation inconvenient and prone to crooked application. Furthermore, traditional tape applicators struggle with quick disassembly for rapid tape removal and reassembly.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a tape applicator that can be quickly disassembled to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: a tape applicator that can be quickly disassembled, comprising: a tape applicator body, which is composed of a first housing and a second housing joined together; the tape applicator body has a receiving cavity for accommodating tape and a central support ring for supporting tape; a through hole is formed at the center of the tape applicator body, and an operating beam is horizontally arranged in the through hole and passes through the center of the through hole; a latching locking unit is provided on both the upper and lower sides of the operating beam, the latching locking unit including a locking groove formed on the first housing and an elastic operating plate arranged in the locking groove, and a limiting protrusion formed on the outer wall of the second housing; the second housing is partially inserted into the first housing, and quick assembly is achieved by the limiting protrusion abutting against the inner wall of the locking groove; pressing the elastic operating plate can cause it to elastically deform, driving the limiting protrusion to disengage from the locking groove, thereby realizing the quick disassembly of the tape applicator body.

[0007] In some embodiments, the operating beam includes a first U-shaped plate formed on a first housing and a second U-shaped plate formed on a second housing. The locking groove is U-shaped and opened on the first U-shaped plate, separating the elastic operating plate from the first U-shaped plate. The inner wall of the locking groove facing the elastic operating plate is the locking surface.

[0008] In some embodiments, a plurality of dividing grooves are formed on the second U-shaped plate, the dividing grooves separating the second U-shaped plate to form an elastic locking plate, and the limiting protrusion is formed on the outer surface of the elastic locking plate.

[0009] In some embodiments, the limiting protrusion extends linearly along the width direction of the elastic locking plate, and a vertical plane that mates with the locking surface is formed on one side of the protrusion, the vertical plane being perpendicular to the elastic locking plate, while a chamfered guide portion is formed on the other side.

[0010] In some embodiments, a guide protrusion with a smooth arc surface is formed on the inner wall of the first U-shaped plate, and the guide protrusion is adjacent to the locking surface.

[0011] In some embodiments, corrugated protrusions are formed on the outer wall of the elastic operating plate.

[0012] In some embodiments, the inner wall of the central support ring is provided with a plurality of L-shaped support seats at equal intervals in the circumferential direction.

[0013] In some embodiments, the bottom of the tape machine body has a first foot and a second foot with a horizontal bottom, wherein the bottom of the second foot is provided with a pulley, and a glue-feeding groove is formed between the first foot and the second foot, the glue-feeding groove communicating with the receiving cavity.

[0014] In some embodiments, an observation groove is formed on one side of the tape machine body, and a gripping extension is formed on the other side. One end of the observation groove extends to the first support leg, and the other end is adjacent to the gripping extension.

[0015] In some embodiments, the first housing has a limiting groove at the edge of the end face that contacts the second housing, and the end face of the second housing has a limiting flange that matches the limiting groove.

[0016] The beneficial effects of this application are as follows: By using the latching and locking units on the upper and lower sides of the operating beam, as well as the limiting groove and limiting flange, the first and second housings that make up the main body of the tape machine can be assembled together. Simply pressing the elastic operating plate on the latching and locking unit will drive the elastic locking plate to undergo elastic deformation, causing the limiting protrusion to disengage from the locking surface, thus enabling the quick separation of the first and second housings for convenient tape replacement. Similarly, assembling the first and second housings only requires re-fitting the limiting protrusion and locking surface.

[0017] In addition, the tape applicator of this application has a first leg for pressing and applying the unfolded tape and a second leg with a pulley, the second leg enabling the tape applicator to move more smoothly and easily. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0028] In the embodiments of this application, please refer to Figure 1-7 As shown, this quick-release adhesive tape applicator mainly includes: a tape applicator body, which is composed of a first housing 1 and a second housing 2 assembled together; the tape applicator body has a receiving cavity 27 for accommodating the tape and a central support ring 3 for supporting the tape; a through hole 4 is formed at the center of the tape applicator body, and the central support ring 3 separates the through hole 4 and the receiving cavity 27; the central support ring 3 is also assembled from the first housing 1 and the second housing 2; an operating beam 5 is horizontally arranged in the through hole 4 and passes through the center of the through hole 4, and both ends of the operating beam 5 are fixed to the through hole 4. On the inner wall of the through hole 4; the upper and lower sides of the operating beam 5 are provided with buckle locking units. The buckle locking unit includes a locking groove 10 formed on the first housing 1 and an elastic operating plate 6 provided in the locking groove 10, as well as a limiting protrusion 7 formed on the outer wall of the second housing 2; the second housing 2 is partially inserted into the first housing 1, and quick assembly is achieved by the limiting protrusion 7 abutting against the inner wall of the locking groove 10; pressing the elastic operating plate 6 can cause it to elastically deform, driving the limiting protrusion 7 to disengage from the locking groove 10, thereby realizing the quick disassembly of the tape machine body.

[0029] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0030] like Figure 4-6 As shown, the operating beam 5 includes a first U-shaped plate 8 formed on the first housing 1 and a second U-shaped plate 9 formed on the second housing 2. The locking groove 10 is U-shaped and opened on the first U-shaped plate 8, separating the elastic operating plate 6 from the first U-shaped plate 8. The inner wall of the locking groove 10 facing the elastic operating plate 6 is the locking surface 11. Specifically, the elastic operating plate 6 is disposed in the middle of the first U-shaped plate 8 and protrudes from the first U-shaped plate 8.

[0031] like Figure 6As shown, a plurality of dividing grooves 12 are formed on the second U-shaped plate 9, specifically two pairs / four dividing grooves 12. The dividing grooves are open grooves. The dividing grooves 12 divide the second U-shaped plate 9 to form an elastic locking plate 13. The limiting protrusion 7 is formed on the outer surface of the elastic locking plate 13. Specifically, the limiting protrusion 7 is formed on the outer surface of the elastic locking plate 13 near the end.

[0032] Furthermore, the limiting protrusion 7 extends linearly along the width direction of the elastic locking plate 13, and a vertical plane 14 is formed on one side to cooperate with the locking surface 11. The vertical plane 14 is perpendicular to the elastic locking plate 13, while a chamfered guide portion 15 is formed on the other side. When the second U-shaped plate 9 and the elastic locking plate 13 are inserted into the first U-shaped plate 8, the chamfered guide portion 15 provides guidance for pressing the elastic locking plate 13 inward, making the insertion of the first U-shaped plate smoother.

[0033] like Figure 4 and Figure 7 As shown, a guide protrusion 16 with a smooth arc surface is formed on the inner wall of the first U-shaped plate 8. The guide protrusion 16 is adjacent to the locking surface 11. The guide protrusion 16 can further extend the lower end surface of the locking surface 11 and also guide the elastic locking plate 13. When the elastic locking plate 13 is inserted into the first U-shaped plate 8, the chamfered guide part 15 and the guide protrusion 16 cooperate with each other to guide the elastic locking plate 13 to deform inward toward the second U-shaped plate 9 until the vertical plane 14 on the limiting protrusion 7 contacts the locking surface 11. At this time, the quick assembly of the first housing 1 and the second housing 2 can be completed. The inner side of the elastic operating plate 6 abuts against the outer side of the elastic locking plate 13. When it is necessary to quickly separate the first housing 1 and the second housing 2, simply press the elastic operating plate 6 to make the vertical plane 14 and the locking surface 11 misaligned, and the unlocking and separation can be completed.

[0034] Specifically, the outer wall of the elastic operating plate 6 is formed with corrugated protrusions 17, which are used to facilitate the pressing of the elastic operating plate 6 by fingers.

[0035] like Figure 3 and Figure 6 As shown, several L-shaped support seats 18 are arranged circumferentially at equal intervals on the inner wall of the central support ring 3. The L-shaped support seats 18 are simultaneously arranged on the first housing 1 and the second housing 2, and are used to directly contact and support the adhesive tape placed in the receiving cavity 27. This can reduce the contact area with the adhesive tape, so that the adhesive tape can rotate more smoothly during use, making the operation smoother.

[0036] like Figure 1-2As shown, the bottom of the tape applicator body has a first horizontal support leg 19 and a second horizontal support leg 20. A pulley 21 is provided at the bottom of the second support leg 20. A glue-feeding groove 22 is formed between the first and second support legs 19 and 20, and the glue-feeding groove 22 communicates with the receiving cavity 27. After the tape is unfolded in the receiving cavity 27, it passes through the glue-feeding groove 22 and extends towards the first support leg 19 to adhere to the working surface. The first support leg 19 can press the tape adhered to the working surface firmly. During use, simply moving the tape applicator in a specific direction (the specific direction is along the length of the tape applicator, and the tape can be continuously unfolded; this can be reasonably determined by those skilled in the art based on the accompanying drawings) will allow the tape to unfold smoothly and steadily. The pulley 21 further improves smoothness and work efficiency.

[0037] Furthermore, the tape applicator body has an observation groove 23 annularly formed on one side and a grip extension 24 formed on the other side. One end of the observation groove 23 extends to the first support leg 19, and the other end is adjacent to the grip extension 24. The grip extension 24 serves as a hand grip for operating the tape applicator during operation; while the observation groove 23 has an opening angle of approximately 180 degrees, which saves material and allows for better observation of the tape's usage status.

[0038] like Figure 5-7 As shown, the first housing 1 has a limiting groove 25 at the edge of the end face that contacts the second housing 2, and the end face of the second housing 2 has a limiting flange 26 that matches the limiting groove 25. The limiting flange 26 is placed in the limiting groove 25, so that the joint between the first housing 1 and the second housing 2 fits more closely.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
