Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a radial glue auxiliary joint. Background Art

[0002] Glue guns have been widely used in construction, electrical and electronic, furniture and other industries. By applying glue, they can achieve good waterproofing, sealing, beautification and other effects.

[0003] However, with the continuous improvement of equipment precision and complexity, traditional glue guns can no longer meet the needs. For example, some parts have annular grooves on the hole wall. When glue is applied to the annular groove, glue must be filled radially from the annular groove to complete the gluing operation. Although traditional glue guns can glue the annular groove from the radial direction of the hole by adding an extension tube or a special-shaped curved nozzle, it is impossible to ensure uniform glue application by rotating and adjusting the position while applying glue, and a hanging knife is required for trimming after gluing, which is not only difficult to operate, but also time-consuming and labor-intensive. Utility Model Content

[0004] In view of this, the utility model provides a radial gluing auxiliary joint, which aims to make radial gluing easier and more uniform.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A radial gluing auxiliary joint, characterized in that: it includes a joint body, a connecting structure is provided on the joint body, an assembly chamber is provided inside, the connecting structure is used to connect with the glue outlet nozzle of the glue bottle, an axial channel is provided on the top of the assembly chamber and passes through the upper end of the joint body upward, and a first radial channel is distributed on the circumferential side wall of the assembly chamber; a rotating plug is rotatably arranged in the assembly chamber, an annular inner cavity is provided inside the rotating plug, the upper end of the annular inner cavity has an opening connected to the axial channel, and blades are distributed in a circular array inside the annular inner cavity, each of the blades divides the annular inner cavity into a plurality of second radial channels, the inner end of each of the second radial channels is connected to the opening, and the outer end of each of the second radial channels passes through the circumferential side wall of the rotating plug.

[0007] By adopting the above structure, through the rotating plug that is rotated and the blades that are evenly distributed circumferentially, when the glue enters the interior of the joint body, it can enter the annular inner cavity along the openings, and then flow evenly circumferentially through the second radial channel between the blades, thereby realizing radial gluing of the annular groove. When radial gluing of the annular groove is required, it is only necessary to place the joint body at the center of the annular groove, which is very convenient to operate.

[0008] Preferably, the bottom of the annular inner cavity is provided with a tapered portion facing the opening, and the axis of the tapered portion can be colinear with the axis of the glue bottle nozzle. The above structure facilitates the glue to evenly transform from an axial position to a circumferential divergence.

[0009] Preferably, the blades are distributed in a spiral array at the circumferential position of the conical portion. The above structure is more conducive to the glue pushing the rotating plug to rotate.

[0010] Preferably, a first bearing is provided between the side of the joint body away from the glue bottle nozzle and the rotating plug, and a second bearing is provided between the side of the joint body close to the glue bottle nozzle and the rotating plug. With the above structure, the first bearing and the second bearing can assist the rotating plug in rotating, thereby making the radial glue application more uniform.

[0011] Preferably, the first bearing is a thrust ball bearing, and the second bearing is a thrust spherical roller bearing. With the above structure, the first bearing and the second bearing can convert the axial pressure of the glue on the rotating plug to disperse it in all directions.

[0012] Preferably, the joint body is provided with a limiting portion in the circumferential direction, and the limiting portion can support the joint body on the surface of the part to be glued. The above structure can play a limiting role and ensure that the auxiliary joint will not shake or deviate when in use.

[0013] Preferably, the joint body is provided with an inwardly contracted annular groove at a position corresponding to the lower edge of the outer end of the first radial channel. With the above structure, when the inside of the part to be glued is filled with glue and then the joint body is pulled out, the side wall of the joint body can act as a scraper, and the excess glue in the annular groove can be used to fill the part of the hole wall of the glued part that is not filled with glue, eliminating the need for subsequent secondary trimming.

[0014] Preferably, the lower end of the assembly chamber is provided with an installation opening, the aperture of the installation opening is greater than or equal to the outer diameter of the rotating plug, a pressure plate is threadedly connected to the installation opening, and the thrust ball bearing is abutted between the pressure plate and the rotating plug. The above structure is adopted to facilitate the installation and disassembly of various parts of the auxiliary joint.

[0015] Preferably, the connection structure is a threaded mounting head. The above structure ensures that the glue bottle nozzle and the auxiliary joint are fixedly mounted.

[0016] As a preferred embodiment: the rotating plug is provided with an open portion facing the glue bottle nozzle on one side close to the glue bottle nozzle, and a connecting ring facing the open portion is provided inside the joint body, and the open portion is sleeved on the outside of the connecting ring. The above structure ensures the assembly accuracy between the rotating plug and the joint body, and also ensures that the glue directly enters the rotating plug from the axial channel, and does not enter the position of the second bearing through other gaps to affect the service life of the second bearing.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The radial gluing auxiliary joint provided by the utility model is adopted, and the axial flow of glue is converted into the rotation of the blade by rotating the rotating plug, thereby achieving the purpose of radially and uniformly gluing the annular groove on the wall of the part hole. In actual use, it is only necessary to place the joint body in the part hole, and the operation is very convenient.

[0019] 2. When the glue fills the radial hole wall, the inside of the annular groove arranged circumferentially on the joint body is also filled with glue. At this time, the joint body is pulled out from the part hole wall. The side wall of the joint body can act as a scraper, and the glue in the annular groove can effectively fill the gaps that still exist on the radial hole wall, eliminating the need for subsequent secondary repairs.

[0029] The utility model is further described below in conjunction with embodiments and drawings.

[0030] This embodiment is described by taking the glue gun as an example to glue the annular groove 7a on the bottom plate of the battery box of a new energy vehicle. Figure 3 The battery box bottom plate 7 is provided with a hanging hole 7b, and the hanging hole 7b has an annular groove 7a on its wall. Since the gap involved in the annular groove 7a is a weld in the manufacturing process of the battery box bottom plate 7, the glue can not only fill the groove, but also play the role of corrosion prevention and shock absorption.

[0031] like Figures 1 to 7 As shown, a radial gluing auxiliary joint comprises a joint body 1, a connection structure 11 is arranged at the upper end of the joint body 1, and an assembly chamber 1a is formed inside the joint body 1. The connection structure 11 is used to connect with the glue outlet of the glue bottle 6, and the circumferential side wall of the assembly chamber 1a is distributed with a first radial channel 1c. A rotating plug 2 is also rotatably installed inside the assembly chamber 1a, and an annular inner cavity 2a is formed inside the rotating plug 2. The upper end of the annular inner cavity 2a has an opening 2b connected to the axial channel 1b, and blades 21 are distributed in a circular array inside the annular inner cavity 2a. Each blade 21 divides the annular inner cavity 2a into a plurality of second radial channels 2c. The inner end of each second radial channel 2c is connected to the opening 2b, and the outer end of each second radial channel 2c passes through the circumferential side wall of the rotating plug 2.

[0032] With such a design, when the glue comes out of the glue outlet of the glue bottle 6, it can enter the annular inner cavity 2a inside the rotating plug 2 through the axial channel 1b and the opening 2b, then enter the first radial channel 1c through the second radial channel 2c, and finally enter the annular groove 7a. The array-distributed blades 21 allow the glue to flow evenly along the circumference to the inside of the annular groove 7a, thereby achieving the purpose of evenly gluing the annular groove 7a.

[0033] like Figures 4 to 6 As shown, a tapered portion 22 facing the opening 2b is formed at the bottom of the annular inner cavity 2a, and the axis of the tapered portion 22 can be colinear with the axis of the glue outlet of the glue bottle 6. This design can help the glue axially entering the annular inner cavity 2a to flow evenly around along the outer surface of the tapered portion 22.

[0034] In this embodiment, the blade 21 is spiral-shaped. Figure 5 Since the rotating plug 2 is rotatably installed inside the joint body 1, the spiral blades 21 allow the glue to spiral into the annular groove 7a, which helps to promote the rotation of the rotating plug 2, thereby ensuring that the glue inside the annular groove 7a is more uniform.

[0035] In order to facilitate the fixed installation of the joint body 1 and the glue nozzle of the glue bottle 6, in this embodiment, the joint body 1 and the glue nozzle of the glue bottle 6 are installed by threads, the connecting structure 11 is a threaded installation head, and the connecting structure 11 is formed on the upper end of the joint body 1.

[0036] In this embodiment, a limiting portion 12 is formed circumferentially on the connector body 1. When the connector body 1 is placed on the hanging hole 7b of the battery box bottom plate 7, the limiting portion 12 can be supported on the outer surface of the hanging hole 7b to play a supporting and limiting role, thereby ensuring that the connector body 1 will not shake when the glue gun 8 is applying glue.

[0037] like Figure 8 As shown, a first bearing 3 is installed between the bottom of the rotating plug 2 and the joint body 1, and a second bearing 4 is installed between the top of the rotating plug 2 and the joint body 1. The first bearing 3 and the second bearing 4 cooperate with each other to assist the rotating plug 2 in rotating, so that the rotating plug 2 rotates more smoothly and the glue can be applied more evenly. In this embodiment, the first bearing 3 is preferably a thrust ball bearing, and the second bearing 4 is preferably a thrust spherical roller bearing. With this design, the first bearing 3 and the second bearing 4 can assist the rotating plug 2 in rotating, and at the same time, can divert the axial pressure of the glue on the rotating plug 2 to the surroundings.

[0038] Furthermore, an open portion 23 is formed on the top of the rotating plug 2, and a vertically downward connecting ring 14 is formed inside the joint body 1, and the open portion 23 is sleeved on the outer ring of the connecting ring 14. Such a design can ensure the assembly accuracy between the rotating plug 2 and the joint body 1, and can ensure that the glue directly enters the open portion 2b from the axial channel 1b, and then diverges circumferentially along the second radial channel 2c, effectively preventing the glue from entering the second bearing 4 from the gap between the joint body 1 and the rotating plug 2, thereby ensuring the service life of the second bearing 4.

[0039] like Figure 7 and Fig. 9 As shown, an inwardly contracted annular groove 13 is provided at the lower edge of the outer end of the joint body 1 corresponding to the first radial channel 1c. When the inside of the annular groove 7a and the annular groove 13 are filled with glue, the joint body 1 is pulled out from the hanging hole 7b. The side wall of the joint body 1 acts as a scraper, and the glue in the annular groove 13 can be used to fill the air bubbles that may exist in the circumference of the annular groove 7a, eliminating the need for secondary trimming with a scraper at a later time.

[0040] In order to facilitate the installation of various parts of the auxiliary joint, in this embodiment, an installation opening is provided at the lower end of the assembly chamber 1a, and the aperture of the installation opening is greater than or equal to the outer diameter of the rotating plug 2. A pressure plate 5 is threadedly connected to the installation opening, wherein the thrust ball bearing is abutted between the pressure plate 5 and the rotating plug 2. Based on this, the rotating plug 2, the first bearing 3 and the second bearing 4 can be installed and removed from the bottom of the joint body 1.

[0041] Based on the above structure, combined Figure 2 and Fig. 9 The steps and principles of the utility model in actual use are as follows: first, select a joint body 1 with a size that is suitable for the hanging hole 7b on the bottom plate 7 of the battery box, spirally install the joint body 1 on the glue outlet nozzle of the glue bottle 6, and place the joint body 1 in the hanging hole 7b. At this time, the limit part 12 is against the outer surface of the bottom plate 7 of the battery box, and the glue gun 8 is pressed to make the glue enter the axial channel 1b from the glue outlet nozzle of the glue bottle 6, and flow directly to the top of the tapered part 22 along the axial channel 1b. Then the glue diverges circumferentially along the outer surface of the tapered part 22, and finally spirally enters the annular groove 7a uniformly along the molding direction of each blade 21. At this time, the first bearing 3 and the second bearing 4 convert the axial pressure exerted by the glue on the rotating disk 2 to diverge circumferentially on the rotating disk 2 and assist the rotating disk 2 to rotate. When the annular groove 7a is filled with glue, the joint body 1 is pulled out from the hanging hole 7b. At this time, the side wall of the joint body 1 acts as a scraper, making the circumferential hole wall of the annular groove 7a smoother. The excess glue in the annular groove 13 can be used to fill the bubbles that may exist in the circumferential hole wall of the annular groove 7a. With this design, radial gluing of the hanging hole 7b is not only more convenient, but also more uniform. The cooperation between the annular groove 13 and the side wall of the joint body 1 saves the subsequent scraper repair step.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
