[0002] Advertising light boxes are a common advertising display tool. Their core feature is that they achieve the effect of illuminating advertising content through internal light sources and box structure, which can significantly enhance visual appeal, especially at night or in low-light environments.

[0003] The box structure is an important component of the advertising light box, mainly serving to support and bear weight. The box structure is usually composed of a frame made of multiple square steel pipes welded together. During the welding process, in order to facilitate operation, a positioning device is also needed to position the multiple square steel pipes.

[0004] A search revealed that currently available positioning devices are complex in structure, inconvenient to operate, and unsuitable for the simultaneous and rapid positioning of multiple steel pipes, thus affecting welding efficiency. Therefore, there is an urgent need to improve existing welding positioning devices for advertising light box manufacturing and to provide a new welding positioning device for advertising light box manufacturing. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a welding positioning device for the manufacture of advertising light boxes that is reasonably designed, simple in structure, and easy to operate, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding positioning device for manufacturing advertising light boxes includes a base, a positioning seat fixedly installed on the top of the base, a positioning component provided on the inner side of the upper end of the positioning seat, a first clamping plate provided between the front and rear sides of the positioning component and the positioning seat, the bottom end of the first clamping plate slidingly against the upper end surface of the positioning seat, a sliding groove provided in the middle of the bottom end of the base, a lead screw provided in the sliding groove, the lead screw being connected to the base bearing, a positioning bolt for positioning the lead screw by contacting it is threaded on the outer right front side of the base, a limit block is fixed on the inner side of the left end of the sliding groove, and a clamping component is provided above the limit block.

[0008] In a preferred embodiment, the longitudinal section of the positioning seat is arranged in a U-shape, and the sliding directions of the two first clamping plates are always opposite to each other.

[0009] In a preferred embodiment, the positioning component includes a fixed box, a crossbar, a movable plate, and a protrusion. The fixed box is fixedly installed in the middle of the inner side of the positioning seat. Crossbars are symmetrically fixed on the inner sides of both the left and right ends of the fixed box. Two movable plates are slidably installed on the inner side of the fixed box in a staggered manner. The two movable plates have protrusions on the left and right sides of the end of the fixed box located inside the fixed box. The protrusions are slidably sleeved on the outer side of the corresponding crossbar. The ends of the two movable plates located outside the fixed box are respectively fixedly connected to the two first clamping plates.

[0010] In a preferred embodiment, both the fixing box and the positioning seat have a through groove structure at the bottom center, and the through groove structure is connected to the sliding groove.

[0011] In a preferred embodiment, the two movable plates are linked together and both have inclined grooves inside, with an inclination angle of 45°, and the inclined grooves inside the two movable plates are symmetrically arranged.

[0012] In a preferred embodiment, the clamping assembly includes a movable rod, a vertical shaft, and a second clamping plate. The movable rod is slidably located inside the slide groove and threaded onto the outside of the lead screw. A vertical shaft is fixedly connected to one end of the movable rod, and a second clamping plate is fixedly installed above the other end of the movable rod.

[0015] In the solution of this utility model:

[0016] Three square steel pipes are placed between the positioning seat and the two first clamping plates, and between the first clamping plate and the second clamping plate. Then, the screw is manually rotated to control the clamping assembly to move to the right. At this time, the vertical shaft can squeeze the inclined groove, thereby pushing the two movable plates to drive the two first clamping plates to slide synchronously in a direction away from each other. The inclination of the inclined groove is 45°, which makes it easy for the sliding displacement of the first clamping plate and the second clamping plate to be consistent, thus facilitating the synchronous and rapid positioning of the three square steel pipes and making it convenient for the welding of the box frame.

[0017] This device can achieve synchronous control of the two first clamping plates and the second clamping plate by rotating the lead screw, which is convenient for positioning multiple square steel pipes at the same time.

[0027] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0028] like Figure 1-6 As shown, the welding positioning device for manufacturing advertising light boxes of this utility model includes a base 1, a positioning seat 2 fixedly installed on the top of the base 1, a positioning component 3 provided on the inner side of the upper end of the positioning seat 2, a first clamping plate 4 provided between the front and rear sides of the positioning component 3 and the positioning seat 2, the bottom end of the first clamping plate 4 slidingly against the upper end surface of the positioning seat 2, a sliding groove 5 opened in the middle of the bottom end of the base 1, a lead screw 6 provided in the sliding groove 5, the lead screw 6 being connected to the base 1 by a bearing, a positioning bolt 7 for positioning the lead screw 6 by threading on the outer wall of the right front of the base 1, a limit block 8 fixed on the inner side of the left end of the sliding groove 5, and a clamping component 9 provided above the limit block 8.

[0029] Based on the above structure, the longitudinal section of the positioning seat 2 is set in a "U" shape, and the sliding directions of the two first clamping plates 4 are always opposite to each other.

[0030] In this embodiment, the positioning seat 2 and the two first clamping plates 4 are used to facilitate parallel positioning of the two steel pipes, which is convenient for welding.

[0031] Based on the above structure, the positioning component 3 includes a fixed box 31, a crossbar 32, a movable plate 33, and a protrusion 34. The fixed box 31 is fixedly installed in the middle of the inner side of the positioning seat 2. The left and right ends of the fixed box 31 are symmetrically fixed with crossbars 32. The inner side of the fixed box 31 is slidably installed with two movable plates 33 in a staggered manner. The two movable plates 33 are provided with protrusions 34 on the left and right sides of the end of the fixed box 31. The protrusions 34 are slidably sleeved on the outer side of the corresponding crossbars 32. The ends of the two movable plates 33 located outside the fixed box 31 are respectively fixedly connected to the two first clamping plates 4.

[0032] In this embodiment, the protrusions 34 and crossbars 32 on the left and right sides of the movable plate 33 are used to improve the smoothness and stability of the movable plate 33 during the telescopic sliding process.

[0033] Based on the above structure, a through groove structure is provided at the bottom center of both the fixed box 31 and the positioning seat 2, and the through groove structure is connected to the sliding groove 5.

[0034] Based on the above structure, the two movable plates 33 are linked together and both have inclined grooves 35 inside. The inclined grooves 35 have an inclination angle of 45° and the inclined grooves 35 inside the two movable plates 33 are symmetrically opened.

[0035] In this embodiment, the inclined groove 35 with an inclination angle of 45° is used to facilitate the synchronous sliding of the clamping component 9 and the movable plate 33, and the sliding displacement of the two is equal.

[0036] Based on the above structure, the clamping assembly 9 includes a movable rod 91, a vertical shaft 92, and a second clamping plate 93. The movable rod 91 is slidably located inside the slide groove 5 and threaded onto the outside of the lead screw 6. The vertical shaft 92 is fixedly connected to one end of the movable rod 91, and the second clamping plate 93 is fixedly installed above the other end of the movable rod 91.

[0037] In this embodiment, when the rotating screw 6 controls the clamping assembly 9 to move, the vertical shaft 92 can be used to squeeze the inclined groove 35, thereby controlling the two movable plates 33 to drive the two first clamping plates 4 to slide synchronously in opposite directions, which facilitates cooperation with the second clamping plate 93 to achieve synchronous and rapid positioning of the three square steel pipes, and facilitates the welding processing of the box frame.

[0038] Based on the above structure, the top end of the vertical shaft 92 passes through the bottom through groove structure of the fixing box 31 and the positioning seat 2 and extends into the inclined groove 35. The positioning seat 2 and the second clamping plate 93 are equally spaced from the first clamping plate 4.

[0039] In this embodiment, since the distance between the positioning seat 2 and the second clamping plate 93 and the first clamping plate 4 is equal, and the displacement of the first clamping plate 4 and the second clamping plate 93 is equal, it is convenient to quickly clamp and position square steel pipes of different sizes.

[0040] The working principle of this utility model is as follows:

[0041] In use, first place two long steel pipes between the two first clamping plates 4 and the positioning seat 2, then place a short steel pipe of the same model as the long steel pipes between the second clamping plate 93 and the first clamping plate 4. Then manually rotate the screw 6 to control the clamping assembly 9 to move stably to the right in the slide 5 under the support of the limit block 8. At this time, the vertical shaft 92 can squeeze the inclined groove 35, which makes it easy to push the two movable plates 33 to drive the two first clamping plates 4 to slide synchronously in a direction away from each other. Moreover, since the inclination of the inclined groove 35 is 45°, the sliding displacement of the first clamping plate 4 and the second clamping plate 93 can be kept consistent, which makes it easy to position the three square steel pipes synchronously and quickly, and facilitates the welding of the box frame.

[0042] This device achieves synchronous control of the two first clamping plates 4 and the second clamping plate 93 by rotating the lead screw 6, which facilitates the simultaneous positioning of multiple square steel pipes. Furthermore, by tightening the positioning bolts 7, the lead screw 6 can be positioned against the contact, ensuring the stability of the working state of the first clamping plates 4 and the second clamping plate 93. This device is simple and quick to operate, highly efficient, and has a simple structure and low manufacturing cost. It can well meet the actual needs of the market, effectively enhance the efficiency of advertising light box frame production, and is highly practical.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
