Description

Technical Field

[0001] This utility model relates to the technical field of spray gun fixing devices, and in particular to a fender spraying device. Background Technology

[0002] When fenders are being painted in the paint shop, workers use handheld spray guns to spray paint the surface. During the process, the placement angle of the fenders needs to be adjusted to improve the paint quality. However, currently, the painting equipment in the workshop is often fixed in place with hooks, which cannot be adjusted as needed. As a result, in order to improve work efficiency, the spray guns can only be placed directly on the ground, which is prone to accidental damage. At the same time, the traditional suspension structure has certain requirements on the height of the workers, which limits the actual use and is very inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fender spraying device that addresses the above-mentioned technical deficiencies. The position of the machine box can be adjusted laterally according to the working position, which facilitates the suspension of the spray gun. The suspension height can also be adjusted as needed to make it convenient for workers of different heights to use.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model includes:

[0005] The track has a support that can move laterally, and two extension rods are symmetrically arranged below the support, with the inner surface of the extension rods being flat.

[0006] The chassis has two through holes symmetrically arranged on it that are slidably connected to the extension rod, and the chassis has a locking device inside that contacts the extension rod. The chassis also has multiple hooks at the front.

[0007] Preferably, the bracket has first rollers symmetrically arranged at the front and rear of the top, and a second roller is arranged at the top of the bracket.

[0008] Preferably, the chassis has symmetrical slide rails on both sides inside, and the locking device includes an adjusting rod, a connecting rod, and a slider; the adjusting rod is installed in the middle of the chassis and has a displacement sleeve on it; the sliders are arranged in pairs and are slidably connected to the slide rails, and one side of the slider is connected to the displacement sleeve through a connecting rod.

[0009] Preferably, the extension rod is provided with uniformly spaced grooves, and the slider side is provided with uniformly spaced meshing teeth that cooperate with the grooves.

[0010] Preferably, the upper sides of the chassis are provided with brake wheels connected to the toothed grooves, and the upper part of the slider is provided with a pressure plate connected to the rotating shaft, and the middle part of the pressure plate is connected to the chassis.

[0011] Preferably, the pressure plate has a displacement hole in the middle.

[0012] Preferably, the upper end of the pressure plate is provided with a friction plate.

[0013] Preferably, a spring sheet is provided between the friction plate and the pressure plate.

[0014] Preferably, the displacement sleeve has a guide hole on its upper part, and the middle part of the chassis has a guide rod connected to the guide hole.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Depending on the working position in the painting workshop, the position of the machine box can be adjusted laterally, so that after the painting operation, the spray gun can be quickly suspended and the position of the fender can be adjusted, saving intermediate time and improving work efficiency.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] Specific implementation method one: Combining Figure 1-7 As shown, a fender spraying device includes: a track 1, a support 2 that can be laterally displaced inside the track 1, two extension rods 201 symmetrically arranged below the support 2, and the inner surface of the extension rods 201 being flat; a housing 3, two through holes 301 symmetrically arranged on the housing 3 and slidably connected to the extension rods 201, the through holes 301 having the same shape as the cross-sectional shape of the extension rods 201, and a locking device 4 that contacts the extension rods 201 inside the housing 3, and multiple hooks 302 arranged at the front of the housing 3;

[0030] In use, the bracket 2 is pushed along the track 1 to adjust the lateral displacement according to the work position required in the spraying workshop, so that the hook 302 on the machine box 3 is close to the worker's work position. After one spraying, the spraying equipment can be quickly suspended, avoiding damage to the spray gun caused by placing it on the ground, which would affect the quality of subsequent spraying, and also saving intermediate preparation time and improving work efficiency. After suspension, the worker can adjust the position of the fender to prepare for the next spraying operation, which is convenient for the worker's actual operation. When the worker's height is different, the suspension position will also be different. For this, the locking device 4 can be operated to disengage from the extension rod 201, thereby driving the machine box 3 to move along the upper and lower directions of the extension rod 201 to complete the height adjustment. After adjustment, the locking device 4 is used to contact and complete the positioning. The operation is simple and convenient. The planar structure of the extension rod 201 can increase the contact area with the locking device 4 and improve the stability of the positioning.

[0031] Preferred embodiments, in combination Figure 2 and Figure 3As shown, the first roller 202 is symmetrically arranged at the front and rear of the top of the bracket 2. The first roller 202 contacts the bottom of the track 1 and supports the bracket 2. The top of the bracket 2 is provided with a second roller 203, which is positioned by contacting the top of the track 1. The use of rollers can deal with paint overspray in the spray painting workshop and is more practical and reliable than the structure of sliding blocks.

[0032] Preferred embodiments, in combination Figure 4-6 As shown, slide rails 303 are symmetrically arranged on both sides inside the housing 3. The locking device 4 includes an adjusting rod 5, a connecting rod 6, and a slider 7. The adjusting rod 5 is installed in the middle of the housing 3, and its two ends are connected to the housing 3 as rotating shafts. The surface is machined with external threads, and a displacement sleeve 501 is provided on the adjusting rod 5. The sliders 7 are arranged in pairs, and the two sliders 7 are respectively connected to the slide rails 303 on both sides. One side of the slider 7 is connected to one end of the connecting rod 6 as a rotating shaft, while the other end of the connecting rod 6 is connected to the displacement sleeve 501 as a rotating shaft. By rotating the adjusting rod 5, the displacement sleeve 501 is moved, thereby pushing the slider 7 to contact the extension rod 201. The positioning and braking are achieved by using friction. The operation is simple and convenient, and after adjustment, the self-locking property of the thread itself can be used to quickly fix it.

[0033] Preferred embodiments, in combination Figure 3 As shown, the extension rod 201 is uniformly provided with toothed grooves 204, and the slider 7 is uniformly provided with meshing teeth 701 that cooperate with the toothed grooves 204 on its side. Through the cooperation of the toothed grooves 204 and the meshing teeth 701, the stability of the slider 7 after contacting the extension rod 201 can be greatly increased.

[0034] Preferred embodiments, in combination Figure 5 and Figure 6 As shown, brake wheels 304 connected to toothed grooves 204 are provided on both sides of the upper part of the housing 3. A pressure plate 702 connected to the rotating shaft is provided above the slider 7. The middle part of the pressure plate 702 is connected to the housing 3. When the slider 7 is in contact with the extension rod 201, the pressure plate 702 does not contact the brake wheel 304. However, when the slider 7 is disengaged from the extension rod 201, it drives the upper end of the pressure plate 702 to continuously approach the brake wheel 304 until it makes contact, thereby generating a certain pressure on the brake wheel 304. This prevents the slider 7 from falling rapidly after it is disengaged from the extension rod 201, thus improving the safety of use.

[0035] Preferred embodiments, in combination Figure 5 and Figure 6 As shown, a displacement hole 703 is provided in the middle of the pressure plate 702, which provides displacement space during the rotation of the pressure plate 702 and avoids structural interference.

[0036] Preferred embodiments, in combination Figure 7As shown, the upper end of the pressure plate 702 is provided with a friction plate 704, which is made of rubber to increase the friction after contacting the brake wheel 304. In order to optimize the structure of the brake wheel 304, the toothed structure on the surface of the friction plate 704 or the pressure plate 702 in direct contact with the brake wheel can be removed to avoid damage to the toothed part and maintain the meshing connection with the extension rod 201.

[0037] Preferred embodiments, in combination Figure 7 As shown, a spring plate 705 is provided between the friction plate 704 and the pressure plate 702, which can prevent excessive contact force during the contact process between the friction plate 705 and the brake wheel 304.

[0038] Preferred embodiments, in combination Figure 5 and Figure 6 As shown, a guide hole 502 is provided above the displacement sleeve 501, and a guide rod 305 connected to the guide hole 502 is provided in the middle of the housing 3. The positioning of the displacement sleeve 501 is achieved by sliding the two together, thereby reducing the force at the connection between the two ends of the connecting rod 6.

[0039] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
