Description

Technical Field

[0001] This utility model relates to the field of wire laying frame technology, and in particular to a portable wire laying frame for wire laying construction. Background Technology

[0002] Setting out lines is a fundamental operation in construction, road, and bridge engineering. Its main task is to accurately set out and position lines according to design drawings. Traditional line setting out methods mostly rely on manual hand tools or fixed line setting frames. While these methods can accomplish the basic tasks, traditional line setting frames are often bulky, especially when they need to be moved between different construction sites. This makes them inconvenient to carry and operate, reducing work efficiency. Furthermore, in traditional line setting out, the reel is usually directly placed on the line setting frame, which makes it difficult to properly set up the reel and the shaft. This can easily cause the shaft to jump out of its groove and fall off, and the height of the shaft cannot be adjusted.

[0003] Therefore, in order to solve the problems existing in the above-mentioned technologies, a portable wire laying frame for wire laying construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a portable wire laying frame for wire laying construction. The bottom frame is connected to the shaft tube of the main support frame. The product can be folded up to save space and greatly enhances the stability of the support frame.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A portable line-laying frame for line-laying construction includes a base frame. Movable grooves are provided at the rear ends of the outer walls on both sides of the base frame. Multiple locking grooves are provided at the front ends of the inner bottom surfaces of the movable grooves. A main support frame is hinged to the front ends of the inner walls on both sides of the base frame. A secondary support frame is rotatably connected to the middle of the inner wall of the main support frame. A rod-placement groove is provided at the rear end of the upper surface of the main support frame. A baffle is rotatably connected to the edge of the rear end of the upper surface of the main support frame. A shaft is provided inside the rod-placement groove.

[0007] The above technical solution features a toothed groove on the side of the bottom frame that connects to the secondary support frame, allowing for quick adjustment of the shaft height. The top of the main support frame is equipped with a rod placement groove and a baffle, enabling quick placement and fixing of the shaft while effectively preventing it from jumping out and falling.

[0008] Furthermore, each of the lower ends of the outer wall of the secondary support frame away from the middle of the bottom frame is rotatably connected to a fixed locking post, and each fixed locking post is engaged with a locking tooth groove.

[0009] The above technical solution allows for a more stable fixation of the secondary support frame by using fixed locking posts.

[0010] Furthermore, a damping spring is provided at the lower end of the baffle, and the two ends of the damping spring are fixedly connected to the main support frame and the baffle, respectively.

[0011] The above technical solution effectively enhances the damping of the baffle plate while allowing it to automatically reset via the damping spring.

[0012] Furthermore, a fixing bolt is provided at the front end of the upper surface of the baffle, and the lower end of the fixing bolt passes through the baffle and the main support frame;

[0013] The above technical solution allows the baffle plate to more securely seal the rod slot by using the fixing bolts.

[0014] Furthermore, a wire guide ring is snapped onto the inner rear wall of the bottom frame;

[0015] The above technical solution allows for easier guidance of the wire harness through the placement of the wire guide ring.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a portable wire laying frame for wire laying construction. It features a new rod placement groove with an openable and closable baffle. The baffle is damped by a damping spring, allowing for opening and closing at any angle. The wire laying frame is a portable folding product with a multi-position adjustable locking tooth groove, enabling quick opening and closing of the entire frame. The shaft is also quickly adjustable. The lower end of the main support frame has a secondary support frame to increase stability, solving the problem of instability during use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] One embodiment provided by this utility model:

[0026] Reference Figure 1 , Figure 2 and Figure 3 :

[0027] A portable line-laying frame for line-laying construction includes a base frame 1. Movable grooves 11 are provided at the rear ends of the outer walls on both sides of the base frame 1. Multiple toothed grooves 8 are provided at the front ends of the inner bottom surfaces of the movable grooves 11. A main support frame 2 is hinged to the front ends of the inner walls on both sides of the base frame 1. A secondary support frame 3 is rotatably connected to the middle of the inner wall of the main support frame 2. A rod-placement groove 10 is provided at the rear end of the upper surface of the main support frame 2. A baffle 7 is rotatably connected to the edge of the rear end of the upper surface of the main support frame 2. A shaft 5 is provided inside the rod-placement groove 10.

[0028] The bottom frame 1 has a toothed groove 8 on its side, which is connected to the auxiliary support frame 3, allowing for quick adjustment of the height of the shaft 5. The top of the main support frame 2 has a rod placement groove 10 and a baffle 7, which can be quickly removed and fixed, and effectively prevent the shaft 5 from jumping out and falling.

[0029] Reference Figure 3 and Figure 4 :

[0030] The lower end of the outer wall of the auxiliary support frame 3, away from the middle of the bottom frame 1, is rotatably connected with a fixing pin 12. The fixing pin 12 engages with the locking tooth groove 8. The fixing pin 12 can more stably fix the position of the auxiliary support frame 3. The lower end of the baffle 7 is provided with a damping spring 4. The two ends of the damping spring 4 are fixedly connected to the main support frame 2 and the baffle 7 respectively. The damping spring 4 can effectively improve the damping of the baffle 7 and make it automatically reset. The front end of the upper surface of the baffle 7 is provided with a fixing bolt 9. The lower end of the fixing bolt 9 passes through the baffle 7 and the main support frame 2. The fixing bolt 9 can more firmly seal the rod groove 10 of the baffle 7. The inner wall of the rear end of the bottom frame 1 is connected with a wire guide ring 6. The wire guide ring 6 can more conveniently guide the wire harness.

[0031] Working principle: In use, by pulling the main support frame 2, one end of the auxiliary support frame 3 is moved. When the main support frame 2 is pulled to a certain angle, the lower end of the auxiliary support frame 3 is fixed in the appropriate tooth groove 8 by the fixing pin 12. Then, the baffle 7 is rotated, and the shaft 5 is placed into the rod placement groove 10. Then, the baffle 7 is released, and the baffle 7 is reset by the torque of the damping spring 4. Then, the baffle 7 closes the rod placement groove 10 and is fixed by the fixing bolt 9. Then, one end of the wire harness is passed through the wire feeding guide ring 6, and the wire harness is pulled to make the wire harness flow out inside the wire feeding guide ring 6.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
