[0027] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0028] like Figure 1-5 As shown, a casing fixing clamp comprises:

[0029] A fixed bracket 1, two movable arms 2 are hinged on the fixed bracket 1, and a connecting spring 3 is provided between the two movable arms 2;

[0030] Two hoop plates 4, the two hoop plates 4 are respectively installed on the corresponding two movable arms 2;

[0031] A connecting frame 41 is provided between the hoop plate 4 and the movable arm 2. Both ends of the connecting frame 41 are provided with hinge seats 42, and the hoop plate 4 is hinged on the hinge seats 42;

[0032] The movable arm 2 is provided with a connecting block 22, which is provided with a connecting groove 221. A connecting piece 411 is hingedly connected to the connecting frame 41. The connecting block 22 is provided with a female connecting hole. The connecting piece 411 is elastically connected to a male connecting portion 412. When the connecting piece 411 is inserted into the connecting groove 221, the male connecting portion 412 springs into the female connecting hole to mount the connecting frame 41 on the movable arm 2.

[0033] The hoop plate 4 is suitable for clamping the sleeve when the two movable arms 2 slide into place.

[0034] In this embodiment, the sleeve fixing clamp is composed of two movable arms 2 and a clamp plate 4. The movable arm 2 and the clamp plate 4 are connected by a connecting frame 41. During the installation process, the operator selects clamp plates 4 of different sizes according to the size of the sleeve and the actual situation on site. The clamp plate 4 and the connecting frame 41 are a standard installation part. The connecting part 411 on the connecting frame 41 is inserted into the connecting groove 221 on the connecting block 22. When installed in place, the male connecting part 412 pops into the female connecting hole to maintain the fixed connection between the movable arm 2 and the connecting frame 41. The hinged seat 42 on the connecting frame 41 can flexibly adjust the position of the clamp plate 4 to better align and fit the sleeve.

[0035] By squeezing the male connecting portion 412 in the female connecting hole to disengage it from the female connecting hole, the connecting piece 411 can be taken out of the connecting groove 221, so that the connecting frame 41 and the clamping plate 4 can be removed, and a suitable clamping plate 4 can be replaced to adapt to sleeves of different sizes. Since the connecting piece 411 is hinged to the connecting frame 41, the connecting frame 41 has a certain degree of rotational freedom on the movable arm 2 after being installed in place.

[0036] Specifically, if Figure 1-4 As shown, the top of the movable arm 2 is hinged with a connecting seat 21, and the connecting spring 3 is installed between the two connecting seats 21. In this embodiment, when the clamping plate 4 clamps or loosens the sleeve, the connecting spring 3 can ease the movement of the movable arm 2, reduce the impact force caused by sudden clamping or loosening, and extend the life of the equipment.

[0037] Specifically, if Figure 1-5 As shown, the casing fixing clamp also includes two synchronization mechanisms, which include a synchronization gear 51, a connecting plate 52 and a connecting rod 53. The synchronization gear 51 is installed on the fixed bracket 1, one end of the connecting plate 52 is connected to the synchronization gear 51, and the other end of the connecting plate 52 is hinged to one end of the connecting rod 53, and the other end of the connecting rod 53 is hinged to the corresponding movable arm 2;

[0038] The synchronizing gear 51 in one synchronizing mechanism meshes with the synchronizing gear 51 in the other synchronizing mechanism.

[0039] Specifically, if Figure 4 As shown, an operating cavity 11 is provided in the fixing bracket 1 , and the synchronization mechanism is arranged in the operating cavity 11 .

[0040] Specifically, if Figure 4 As shown, the synchronization mechanism further includes a mounting shaft 54 , which is mounted in the operating chamber 11 , and the synchronization gear 51 is rotatably mounted on the mounting shaft 54 .

[0041] In this embodiment, the synchronizing gear 51 in one synchronizing mechanism is rotatably mounted on the mounting shaft 54 of the fixed bracket 1 and meshes with the synchronizing gear 51 in the other synchronizing mechanism. This arrangement ensures that the synchronizing gears 61 in the two synchronizing mechanisms maintain synchronous rotation, thereby ensuring that the two movable arms 2 maintain synchronous movement during the sliding process.

[0042] Specifically, if Figure 1-4 As shown, the hoop plate 4 is semicircular and is provided with an anti-skid pad. It can provide additional friction when the hoop plate 4 is clamped, ensuring that the sleeve will not slide or shift due to the clamping action of the hoop plate. At the same time, the anti-skid pad can protect the sleeve and prevent the hoop plate 4 from scratching the sleeve surface.

[0043] Specifically, if Figure 1-4 As shown, the casing fixing clamp also includes a driving mechanism, which includes a driving bracket 61 and a driving motor 62. The driving bracket 62 is installed on the fixing bracket 1, and the driving motor 62 is installed on the fixing bracket 1. The movable end of the driving motor 62 is connected to one of the synchronous gears 51. The driving motor 62 is suitable for driving one of the synchronous gears 51 to rotate to drive the other synchronous gear 51 to rotate, so that the synchronous rotation of the two movable arms 2 drives the clamp plate 4 to clamp the casing.

[0044] In this embodiment, the drive motor 62 drives a synchronous gear 51 connected thereto to rotate counterclockwise. Since the two synchronous gears 51 are meshed, the other synchronous gear 51 also rotates counterclockwise. The two synchronous gears 51 drive the two connecting plates 52 to rotate in opposite directions to drive the two movable arms 2 to rotate inward synchronously, and the hoop plate 4 then moves closer to the casing. When the hoop plate 4 approaches the casing, due to the force of the movable arm 2, the hoop plate 4 rotates along the hinge point, so that the semicircular hoop plate 4 can adapt to the casing. In the process of approaching and clamping, the connecting frame 41 also rotates to a certain extent to cooperate with the hoop plate 4 to better clamp the casing.

[0045] When the sleeve needs to be released, the driving motor 62 drives a synchronous gear 51 connected to it to rotate clockwise. Since the two synchronous gears 51 are engaged, the other synchronous gear 51 also rotates clockwise. The two synchronous gears 51 drive the two connecting plates 52 to rotate toward each other so that the movable arm 2 rotates outward, and the hoop plate 4 moves away from the sleeve to achieve loosening.

[0046] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
