Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a rotatable angled elbow primer application device. Background Technology

[0002] Currently, composite material tailgates and plastic bumpers are widely used in the automotive market. Radar brackets, camera brackets, and switch brackets on these tailgates and bumpers are typically bonded to the surface using a primer and acrylic or polyurethane tape. Due to their design, many structures have very narrow spaces, lacking sufficient operating and working space to apply the primer. This results in incomplete primer application to areas requiring it, leading to bonding failure.

[0003] With the development of the current automotive market, more and more car brands are developing models with composite material tailgates and bumpers, and the designs are becoming increasingly streamlined and sharper in certain areas. As a result, the bonding space for components such as radar brackets, camera brackets, and switch brackets is becoming increasingly three-dimensional and narrow. Therefore, in production, conventional brush bottles are no longer sufficient to solve assembly and application problems, and cannot complete the multi-dimensional, three-dimensional primer application within confined spaces.

[0004] CN206933706U discloses a detachable curved brush, where the quick disassembly and stable connection between the brush handle and brush head prevents axial sliding and radial rotation, improving work efficiency in hard-to-reach areas. CN202375384U discloses a convenient curved brush for cleaning the inside of cups. While the above-mentioned curved brushes can achieve cleaning in confined spaces, neither of these solutions can simultaneously apply and evenly coat the primer, making them unsuitable for primer application; nor can they be used to perform rotational work in the X, Y, and Z planes within confined spaces, failing to meet the required angles for work on various planes.

[0005] Therefore, a new type of elbow-shaped primer application device still needs to be developed to achieve multi-angle primer application in the confined space of primer application. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot perform multi-angle primer application in confined spaces, and to provide a rotatable elbow primer application device.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A rotatable elbow primer application device, comprising a primer brush head, a rotating head, an elbow fixing seat, and a primer bottle for loading primer liquid connected in sequence, wherein the rotating head, the elbow fixing seat, and the primer bottle are internally connected and form a primer liquid flow channel.

[0009] The elbow fixing seat includes a fixing section, an elbow section, and a connecting section connected in sequence; wherein, the fixing section of the elbow fixing seat is connected to the primer bottle, the connecting section can be fitted with a rotating head and is provided with a sealing element on the outer sleeve of the connecting section, and the rotating head can rotate around the connecting section of the elbow fixing seat.

[0010] Furthermore, the rotating head includes a rotating head threaded section and a rotating transition section integrally connected to the rotating head threaded section.

[0011] Furthermore, the end of the primer brush head is provided with an internal thread that mates with the threaded section of the rotating head.

[0012] Furthermore, the inner diameter of the rotary transition section is larger than the outer diameter of the connecting section of the elbow fixing seat.

[0013] Furthermore, the connecting section between the rotating head and the elbow fixing seat is engaged by friction.

[0014] Furthermore, the connecting section of the elbow fixing seat is provided with a sealing element mounting groove for positioning the sealing element.

[0015] Furthermore, the sealing element is a sealing ring.

[0016] Furthermore, the axial direction of the fixed section is perpendicular to the axial direction of the connecting section.

[0017] Furthermore, the primer bottle includes a bottle body and a threaded section of the primer bottle connected to the bottle body.

[0018] Furthermore, the fixing section of the elbow fixing seat is provided with an internal thread that mates with the threaded section of the primer bottle.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The bent-head primer application device of this utility model can freely rotate the primer brush head, find the appropriate operating angle and extend into the narrow space, so as to solve the primer application operation in the narrow space and in different directions, effectively solving the problem that conventional primer application brush heads cannot extend into the work area to apply primer.

[0021] (2) The bent-head base coat application device of this utility model can perform base coat application on planes at various angles in a narrow space, effectively improving the production efficiency and quality of automotive parts such as composite material tailgates and plastic bumpers.

[0022] (3) The bent-head primer application device of this utility model can evenly apply primer to the bonding area of ​​radar bracket, camera bracket and switch bracket in a narrow space during the production of automotive tailgate and bumper assembly parts, i.e. the area that needs to be coated with primer, thereby completing the primer application operation before bonding, thus ensuring that the primer can be evenly covered in areas where ordinary primer brush head cannot apply primer.

[0023] (4) The overall structure of the elbow primer application device of this utility model is compact. It can be detached through modular design, making it suitable for operation in narrow spaces and reducing space restrictions. The internal connection design of the rotating head, elbow fixing seat and primer bottle can ensure smooth flow of primer liquid, avoid interruption or blockage, and achieve continuous liquid supply.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] Example 1:

[0042] This embodiment provides a rotatable elbow-shaped primer application device. For example... Figure 1 As shown, the elbow primer application device of this embodiment includes a primer brush head 1, a rotating head 2, an elbow fixing seat 3, and a primer bottle 4 for loading primer liquid, which are connected in sequence. The interiors of the rotating head 2, the elbow fixing seat 3, and the primer bottle 4 are interconnected and form a primer liquid flow channel for primer liquid circulation.

[0043] The elbow fixing base 3 of this embodiment includes a fixing section 31, an elbow section 32, and a connecting section 33 connected in sequence. The fixing section 31 of the elbow fixing base 3 is connected to the primer bottle 4. The connecting section 33 of the elbow fixing base 3 can be fitted with a rotating head 2, and a sealing element 5 is provided on the outer sleeve of the connecting section 33. The rotating head 2 can rotate around the connecting section 33 of the elbow fixing base 3.

[0044] This embodiment utilizes a bent-head primer application device, which allows the primer brush head 1 to rotate freely according to actual needs, find a suitable operating angle, and extend into narrow spaces. This solves the problem of construction operations in narrow spaces and in the X, Y, and Z directions, effectively addressing the issue that conventional primer application brush heads cannot reach the work area or adjust their angle, thus preventing primer application.

[0045] Example 2:

[0046] This embodiment provides a rotatable elbow primer application device. The elbow primer application device of this embodiment includes a primer brush head 1, a rotating head 2, an elbow fixing seat 3, and a primer bottle 4 for loading primer liquid, which are connected in sequence. The rotating head 2, the elbow fixing seat 3, and the primer bottle 4 are internally connected and form a primer liquid flow channel for the primer liquid to flow.

[0047] like Figure 2 As shown, the rotating head 2 in this embodiment includes a rotating head threaded section 21 and a rotating transition section 22 integrally connected with the rotating head threaded section 21. The end of the primer brush head 1 is provided with an internal thread that mates with the rotating head threaded section 21, so that the primer brush head 1 and the rotating head 2 are threadedly connected.

[0048] like Figure 3-5 As shown, the elbow fixing base 3 of this embodiment includes a fixing section 31, an elbow section 32, and a connecting section 33 connected in sequence. The bending angle of the elbow section 32 is 90°, so that the axial direction of the fixing section 31 is perpendicular to the axial direction of the connecting section 33. The elbow section 32 of the elbow fixing base 3 allows the device to bypass obstacles in confined spaces, facilitating operation.

[0049] The fixing section 31 of the elbow fixing seat 3 is connected to the primer bottle 4. For example... Figure 6 As shown, the primer bottle 4 includes a bottle body 41 and a primer bottle threaded section 42 connected to the bottle body 41. The fixing section 31 of the elbow fixing seat 3 is provided with an internal thread that mates with the primer bottle threaded section 42, so that the primer bottle 4 is threadedly connected to the elbow fixing seat 3, which facilitates the disassembly of the elbow fixing seat 3 and the replenishment of primer liquid into the primer bottle 4.

[0050] The rotating head 2 and the connecting section 33 of the elbow fixing seat 3 are engaged by friction. The inner diameter of the rotation transition section 22 of the rotating head 2 is larger than the outer diameter of the connecting section 33, allowing the connecting section 33 of the elbow fixing seat 3 to fit into the rotating head 2. A sealing element 5 is sleeved on the connecting section 33 of the elbow fixing seat 3, and a sealing element mounting groove 331 for positioning the sealing element 5 is correspondingly provided on the connecting section 33 of the elbow fixing seat 3. Through the cooperation of the rotating head 2, the elbow fixing seat 3, and the sealing element 5, the rotating head 2 can rotate freely around the connecting section 33 of the elbow fixing seat 3. In this embodiment, the sealing element 5 is a conventional sealing ring.

[0051] Example 3:

[0052] This embodiment provides a rotatable elbow-shaped primer application device. In practical use, Figure 7 This is a partial view of the area where a primer additive is applied. Figure 8 These two figures show a cross-sectional view of the primer application area. As can be seen, the primer application area is a narrow region, covering the X, Y, and Z planes. In this narrow structure, the elbow-shaped primer application device of this embodiment is required to complete the application.

[0053] This utility model's elbow-shaped primer application device can evenly apply primer to the bonding areas of radar brackets, camera brackets, and switch brackets—areas requiring primer application—in confined spaces during the production of automotive tailgates, bumper assemblies, and other parts. This completes the primer application work before bonding, ensuring even coverage of primer even in areas inaccessible to ordinary primer brushes, thus facilitating subsequent bracket bonding and assembly.

[0054] Specifically, the elbow primer application device in this embodiment mainly consists of a primer brush head 1, a rotating head 2, an elbow fixing seat 3, a primer bottle 4, and a sealing element 5. The primer brush head 1 and the rotating head 2 are connected by threads, and the rotating head 2 and the elbow fixing seat 3 are engaged by friction. When engaged, the sealing ring (sealing element 5) is pressed together to achieve a seal, allowing for rotational angle switching. The elbow fixing seat 3 and the primer bottle 4 are connected by threads for easy disassembly.

[0055] The working principle of the elbow primer application device in this embodiment is as follows:

[0056] First, pour the primer additive into the primer bottle 4, then tighten the threads of the elbow fixing seat 3 onto the threads of the primer bottle 4. After tightening, put the sealing ring into the sealing ring installation position (i.e., the sealing element installation groove 331) on the elbow fixing seat 3. After installing the sealing ring, put the rotating head 2 into the elbow fixing seat 3, and finally tighten the primer brush head 1 onto the threads of the rotating head 2.

[0057] After completing the above steps, production staff can use this elbow-shaped primer applicator in production. When using it, align the brush head with... Figure 8 The X, Y, and Z planes are extended into the narrow space by the bending design of the elbow fixing seat 3. At the same time, the angle of the primer brush head 1 can be manually rotated to complete the application of the primer. Figure 7-8 Apply the primer evenly to the area shown in the diagram.

[0058] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
