Detailed implementation manners

[0022] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] Embodiment 1:

[0024] A general-purpose closed-type clamp for insulators, as Figures 1 to 2 shown, includes a clamping body 1, a clamping cover 2 and a fixing member 3. One end of the clamping cover 2 is rotatably connected to one end of the clamping body 1. Specifically, one end of the clamping cover 2 is rotatably connected to one end of the clamping body 1 through a rotating shaft 12.

[0025] The clamping cover 2 and the clamping body 1 cooperate to form a bayonet 4. At least two clamping jaws 5 are rotatably arranged on both the clamping body 1 and the clamping cover 2. In this embodiment, there are four clamping jaws 5 in total and they are evenly distributed along the circumference of the bayonet 4. The clamping jaws 5 are rotatably arranged on the clamping body 1 and the clamping cover 2 through corresponding positioning shafts 13.

[0026] Avoiding grooves 11 for allowing the clamping jaws 5 to rotate are formed on the inner side walls of both the clamping cover 2 and the clamping body 1. The avoiding grooves 11 are V-shaped and correspond to the clamping jaws 5 one by one, so as to effectively avoid the movement tracks of the clamping jaws 5.

[0027] A first positioning groove 6 is formed at the other end of the clamping cover 2, and a second positioning groove 7 is formed at the other end of the clamping body 1. The first positioning groove 6 corresponds to the second positioning groove 7, and the fixing member 3 is detachably arranged in the first positioning groove 6 and the second positioning groove 7.

[0028] Specifically, a first magnetic block 8 and a second magnetic block 9 are respectively arranged in the first positioning groove 6 and the second positioning groove 7. The fixing member 3 is made of magnetically attractive metal, and both the first magnetic block 8 and the second magnetic block 9 cooperate with the fixing member 3 for magnetic attraction.

[0029] As another solution, magnets magnetically attractive to the first magnetic block 8 and the second magnetic block 9 can also be arranged on the fixing member 3.

[0030] It should be noted that when the fixing member 3 is located in the positioning groove 1 6 and the positioning groove 2 7, the magnetic attraction can effectively ensure the stability of the fixing member 3 in the positioning groove 1 6 and the positioning groove 2 7, and the fixing member 3 cannot easily separate from the positioning groove 1 6 and the positioning groove 2 7 without the action of external force; on the contrary, when the fixing member 3 needs to separate from the positioning groove 1 6 and the positioning groove 2 7, it is necessary to apply sufficient external force to the fixing member 3 so that it can overcome the magnetic attraction force and separate from the positioning groove 1 6 and the positioning groove 2 7.

[0031] Furthermore, the shape of magnet 18 is the same as the cross-section of positioning groove 16, and magnet 18 is arranged at the bottom of positioning groove 16. The shape of magnet 29 is the same as the cross-section of positioning groove 27, and magnet 29 is arranged at the bottom of positioning groove 27. It should be noted that when the fixing member 3 is inserted into positioning groove 16 and positioning groove 27, magnet 18 located at the bottom of positioning groove 16 and magnet 29 located at the bottom of positioning groove 27 will produce a strong magnetic attraction with the fixing member 3, which helps to complete the rapid installation and positioning of the fixing member 3, thereby improving the installation efficiency and further improving the stability of the fixing member 3.

[0032] When the fixing member 3 is inserted into the positioning groove 1 6 and the positioning groove 2 7, the card body 1 and the card cover 2 remain relatively fixed. Specifically, the fixing member 3 is matched with the positioning groove 1 6 and the positioning groove 2 7. The cross-section of the positioning groove 1 6 is an inverted trapezoid, and the cross-section of the positioning groove 2 7 is a regular trapezoid. Since the two side edges of the trapezoidal structure are inclined, the positioning groove 1 6 and the positioning groove 2 7 restrict the fixing member 3. After the fixing member 3 is inserted into the positioning groove 1 6 and the positioning groove 2 7, the card body 1 and the card cover 2 cannot be separated due to the cooperation between the positioning groove 1 6 and the positioning groove 2 7 and the fixing member 3, and the fixing member 3 is matched with the positioning groove 1 6 and the positioning groove 2 7, the card body 1 and the card cover 2 remain relatively fixed. When the fixing member 3 is disengaged from the positioning groove 1 6 and the positioning groove 2 7, the card cover 2 can be separated from the card body 1 by rotation, and the user can rotate the card cover 2 by external force to open it.

[0033] When the card cover 2 needs to be opened, it is only necessary to use external force to make the fixing member 3 disengage from the positioning groove 1 6 and the positioning groove 2 7. When the card cover 2 needs to be closed, it is only necessary to use external force to insert the fixing member 3 into the positioning groove 1 6 and the positioning groove 2 7. The operation of opening and closing the card cover 2 is simplified, which can effectively improve work efficiency.

[0034] When the fixing member 3 is inserted into the positioning groove 1 6 and the positioning groove 2 7 , the outer end surface of the fixing member 3 is flush with the outer surface of the card body 1 and the outer surface of the card cover 2 , thereby avoiding collision or friction during use, and effectively reducing space occupancy, which is more conducive to transportation.

[0035] Two oppositely arranged notches 10 are formed at the outer end of the fixing member 3. Both notches 10 are semi-circular and are respectively located on both sides of the fixing member 3. The notches 10 can provide a force application point for the operator, facilitating the operator to take out the fixing member 3 from the first positioning groove 6 and the second positioning groove 7, making the operation more convenient and effectively improving the efficiency.

[0036] Embodiment 2:

[0037] The difference between Embodiment 2 and Embodiment 1 is that, as Figure 3 shown, the cross-section of the first positioning groove 6 is an inverted T shape, and the cross-section of the second positioning groove 7 is a regular T shape. The fixing member 3 is adapted to the first positioning groove 6 and the second positioning groove 7. The fixing member 3 can only be inserted into or disengaged from the first positioning groove 6 and the second positioning groove 7 in one direction. The first positioning groove 6 and the second positioning groove 7 form a restriction on the fixing member 3. Therefore, after the fixing member 3 is inserted into the first positioning groove 6 and the second positioning groove 7, due to the cooperation between the first positioning groove 6 and the second positioning groove 7 and the fixing member 3, the clamping body 1 and the clamping cover 2 cannot be separated, and the clamping body 1 and the clamping cover 2 remain relatively fixed.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention; those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
