DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments, but the present utility model is not limited to the following embodiments.

[0025] Example 1:

[0026] See the appendix Figures 1 to 3. A cable support for teaching and training, comprising a main support 1, a top plate 2 and a plurality of fixing clamps 3; the top plate 2 is arranged above the main support 1; at the front and rear ends of the top plate 2, there is respectively provided a fixing and mounting part 21 for detachably mating with the fixing clamp 3; on the top plate 2, there are provided two adjusting and mounting parts 22, and the two adjusting and mounting parts 22 are symmetrically arranged along the transverse axis of the center of the top plate 2; each adjusting and mounting part 22 is used for enabling at least one fixing clamp 3 to be inserted and slide along the length direction of the top plate 2 to a required mounting position and then be fixed; among the plurality of fixing clamps 3, at least one fixing clamp 3 is used for mounting a counterweight; the main support 1 comprises two folding frames 11 and two fixing rods 12; each folding frame 11 comprises a first support rod 111 and a second support rod 112; the top ends of each first support rod 111 and the second support rod 112 are rotatably connected through a first hinge point 113; the lower end of the first support rod 111 is fixedly connected with a first movable rod 114, and the lower end of the second support rod 112 is connected with a second movable rod 115; the inner sides of the first movable rod 114 and the second movable rod 115 are rotatably connected through a second hinge point 116; the two first support rods 111 are laterally connected by one fixing rod 12, and the two second support rods 112 are laterally connected by another fixing rod 12. From the above structure, it can be seen that the main support 1 serves as the basis for mounting the top plate 2 and is used to provide support for the top plate 2 and the fixing clamps 3 mounted on the top plate 2. At the front and rear ends of the top plate 2, there is respectively provided a fixing and mounting part 21, and on each fixing and mounting part 21, a fixing clamp 3 with an unadjustable position is detachably mated. On the top plate 2, there are provided two adjusting and mounting parts 22, and the two adjusting and mounting parts 22 are symmetrically arranged along the transverse axis of the center of the top plate 2. The adjusting and mounting part 22 is used for enabling at least one fixing clamp 3 to be inserted therein and enabling the fixing clamp 3 to slide along the length direction of the top plate 2 to adjust the mounting position. After the fixing clamp 3 is adjusted to a suitable mounting position, it is then fixed. The fixing clamp 3 is a prior art, and specifically, two metal semi-circular ring clamps can be selected. One end of the two semi-circular ring clamps is hinged, and the other end is fixed by bolts. At least one fixing clamp 3 is mounted on each adjusting and mounting part 22, and the number of fixing clamps 3 on the two adjusting and mounting parts 22 is adjusted according to the actual cable situation. Since the cable may cause the instability of the entire support structure due to the offset of the center of gravity after being fixed in position by a plurality of fixing clamps 3, therefore, among the plurality of fixing clamps 3, at least one fixing clamp 3 is used for mounting a counterweight to adjust the center of gravity of the main support 1 and prevent the main support 1 from tipping over or toppling, so as to ensure the stability of the overall structure after the cable is installed. In addition, since operations such as stripping the cable are carried out during training, which further changes the center of gravity of the main support 1 and makes it inconvenient to continue the training operation, the cable is often discarded directly after being used one or two times. However, the present utility model can ensure the stability of the main support 1 by increasing the counterweight and adjusting the position of the counterweight, so that the same section of cable can be used multiple times and repeatedly, saving the training cost.The main support 1 includes two folding frames 11 and two fixed rods 12. The two folding frames 11 are respectively arranged below the front end and the rear end of the top plate 2. Each folding frame 11 includes a first support rod 111 and a second support rod 112. The top ends of each first support rod 111 and the second support rod 112 are rotatably connected through a first hinge point 113. The lower end of the first support rod 111 is fixedly connected with a first movable rod 114, and the lower end of the second support rod 112 is connected with a second movable rod 115. The inner sides of the first movable rod 114 and the second movable rod 115 are rotatably connected through a second hinge point 116. Such a setting enables the folding frame 11 to expand to the left and right sides or fold and store in the middle. The two first support rods 111 are laterally connected by a fixed rod 12, and the two second support rods 112 are laterally connected by another fixed rod 12. After the two fixed rods 12 laterally fix and connect the two folding frames 11, the two folding frames 11 can synchronously extend to the left and right sides to support the top plate 2, or synchronously fold in the middle, facilitating storage and movement. The utility model can ensure the stability of the overall structure after the cable is installed, and also facilitate storage and movement.

[0027] Embodiment 2:

[0028] See attachment Figures 1 to 4 . On the basis of Embodiment 1, an installation screw 31 is provided at the lower end of the fixed clamp 3. The lower end of the installation screw 31 is threadedly matched with a first fixing nut 32 and a second fixing nut 33. The first fixing nut 32 is arranged above the second fixing nut 33. It can be seen from the above structure that this setting is to insert and fix the lower end of the fixed clamp 3 into the adjustment and installation part 22. When installing the fixed clamp 3, the second fixing nut 33 can be removed first, and the installation screw 31 is inserted downward from above the adjustment and installation part 22 so that the first fixing nut 32 is located above the adjustment and installation part 22. Then, the second fixing nut 33 is screwed onto the screw part of the installation screw 31 from below the adjustment and installation part 22, so that the first fixing nut 32 and the second fixing nut 33 clamp from the upper and lower sides of the adjustment and installation part 22 to complete the fixation of the fixed clamp 3.

[0029] The adjusting and mounting part 22 has a number of alternately arranged and interconnected insertion openings 221 and fixing openings 222; the size of the first fixing nut 32 is smaller than the size of the insertion opening 221, and the size of the second fixing nut 33 is larger than the size of the insertion opening 221; the sizes of the first fixing nut 32 and the second fixing nut 33 are both larger than the size of the fixing opening 222. From the above structure, it can be seen that the size of the mounting screw 31 is smaller than the sizes of the first fixing nut 32 and the second fixing nut 33. The size of the first fixing nut 32 is set smaller than the size of the insertion opening 221, and the size of the second fixing nut 33 is larger than the size of the insertion opening 221, so that the mounting screw 31 can be inserted into the adjusting and mounting part 22 from the insertion opening 221. At this time, when the second fixing nut 33 is screwed onto the mounting screw 31 from below the adjusting and mounting part 22, it can prevent the fixing clamp 3 from falling out when sliding in the adjusting and mounting part 22. When the fixing clamp 3 slides to the required mounting position, that is, the suitable fixing opening 222, then the first fixing nut 32 and the second fixing nut 33 located on the upper and lower sides of the fixing opening 222 are clamped towards the middle, and the installation of the fixing clamp 3 can be completed. In addition, before the first fixing nut 32 and the second fixing nut 33 are clamped, the fixing clamp 3 still has a certain amount of movement space. Therefore, at this time, the fixing clamp 3 can rotate relative to the top plate 2 to adjust the installation angle of the cable.

[0030] The shapes of the insertion opening 221 and the fixing opening 222 are both rectangular. From the above structure, it can be seen that the shapes of the insertion opening 221 and the fixing opening 222 are both rectangular, and the size of the insertion opening 221 is larger than that of the fixing opening 222, which is convenient for the insertion of the fixing clamp 3 and enables the first fixing nut 32 and the second fixing nut 33 to cooperate with the plate members around the fixing opening 222 to clamp during fixation.

[0031] The fixing and mounting part 21 is provided with a fixing and mounting opening 211 whose size is smaller than the sizes of the first fixing nut 32 and the second fixing nut 33. From the above structure, it can be seen that the fixing clamp 3 is fixedly mounted on the fixing and mounting part 21 by clamping the plate material around the fixing and mounting opening 211 with the first fixing nut 32 and the second fixing nut 33. Although it cannot slide, at least four fixing clamps 3 are installed on the top plate 2 of the present utility model, which can not only increase the strength of cable fixation, but also increase the overall structural stability by flexibly adjusting the installation position.

[0032] Embodiment Three:

[0033] See attached Figures 1 to 4。Based on the second embodiment, a pressing component is provided at the upper end of the fixed fixture 3; the pressing component includes a pressing rod 34, a handle 35 and an arc-shaped pressing plate 36; a threaded cylinder 37 is also vertically penetrated through the upper end of the fixed fixture 3; a threaded mating portion 341 is provided at the lower part of the pressing rod 34, and the threaded mating portion 341 has an external thread that mates with the internal thread of the threaded cylinder 37; the threaded mating portion 341 passes through the threaded cylinder 37 and extends into the inner side of the fixed fixture 3; the handle 35 is fixedly arranged at the upper end of the pressing rod 34; the arc-shaped pressing plate 36 is recessed upward and is fixedly arranged at the lower end of the threaded mating portion 341. From the above structure, it can be seen that ordinary fixtures cannot adapt to various models of cables. Therefore, in the present utility model, a pressing component is provided at the upper end of the fixed fixture 3, and the arc-shaped pressing plate 36 is used to perform secondary pressing on the cable from top to bottom, further improving the fixing effect on the cable. The setting of the handle 35 facilitates the trainees to hold and rotate the pressing rod 34, thereby adjusting the position of the arc-shaped pressing plate 36 to adapt to cables with different diameters.

[0034] It further includes two tool trays 4; the two tool trays 4 are respectively detachably connected to the left side and the right side of the main bracket 1. From the above structure, it can be seen that since there are many trainees during teaching and training, the tools used are easily lost. Therefore, the tool trays 4 are provided to store the tools. Since there are trainees on both sides of the bracket during training, two tool trays 4 are provided, and one tool tray 4 is provided on each of the left side and the right side of the main bracket 1, so that the trainees on both sides of the main bracket 1 can place the tools on their respective sides. The two tool trays 4 are respectively detachably connected to the left side and the right side of the main bracket 1, and can be removed when the tool trays 4 are not needed, which is convenient for folding and storing the main bracket 1.

[0035] It further includes four fasteners 5; an ear plate is provided at the lower end of each first support rod 111 and the lower end of each second support rod 112; a fastener 5 is cooperatively provided on each ear plate. From the above structure, it can be seen that in order to increase the stability of the overall structure, the main bracket 1 can be fixed to the externally provided bottom plate through the fasteners 5.

[0036] The number of the fixed fixtures 3 is four. From the above structure, it can be seen that the number of the fixed fixtures 3 is set to four in order to reduce the use cost of the equipment on the premise of ensuring the fixing effect on the cable and the stability of the overall structure after installing the cable.

[0037] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
