Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the azimuth or positional relationships indicated by the azimuth terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal", and "top, bottom", etc., are generally based on the azimuth or positional relationships shown in the drawings, merely to facilitate description of the present utility model and simplify the description, and these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the scope of protection of the present utility model: the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "upper surface on … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The utility model provides a technical scheme that: the jacket of the hydraulic flat-pushing clamp is shown in fig. 1-5, the jacket 10 is circular, a clamp block groove 5 is arranged in the middle of the front end of the jacket 10, the upper side and the lower side of the clamp block groove 5 are arc-shaped, and clamp blocks 9 are arranged in the clamp block groove 5. A fixed bolt hole 1 is formed in the center of the clamping block groove 5, and a bolt penetrates through the fixed bolt hole 1 when the clamping sleeve 10 is installed to be connected with the flat pushing clamp 11, so that the clamping sleeve 10 is connected with the flat pushing clamp 11. Four corners in the clamping block groove 5 are also provided with four clamping block fixing bolt holes 4 which are connected with the clamping blocks 9 through bolts for installing and fixing the clamping blocks 9. In addition, the left and right sides of the clamp block groove 5 are provided with anti-seize bolt holes 2, which in order to prevent the jacket 10 from being seized by the flat push clamp 11 during installation, the anti-seize bolt holes 2 pass through the side base material of the clamp block groove 5, the purpose of which is to facilitate clamping of the clamp block 9.

The inner surface of the clamping block groove 5 is also provided with elliptic anti-sticking patterns 3 which are uneven so as to prevent the back surface of the clamping block 9 from being stuck to the surface of the clamping sleeve groove 5, thus facilitating installation. Since an oily substance is generally used to increase lubrication during installation, if the back of the clamp block 9 and the clamp block groove 5 are both planar, the clamp block 9 and the clamp block groove 5 will stick together over time.

The jacket 10 should be able to withstand sufficient tensile forces. Structurally, the height of the clamping block groove 5 is smaller than or equal to that of the stress column 6, so that the clamping sleeve 10 is stressed more, and the clamping sleeve 10 is prevented from being deformed or damaged due to stress.

During installation, the flat pushing clamp 11 is in a shape corresponding to the flat pushing clamp, most of the jacket 10 can be wrapped in the flat pushing clamp 11, and the left part is not wrapped in the flat pushing clamp for convenient assembly and disassembly.

The shape of the clamping block 9 is the same as that of the clamping block groove 5, the upper side and the lower side are arc-shaped, the clamping block 9 is provided with bolt holes 7 corresponding to the clamping block fixing bolts 4 on the clamping sleeve 11, the middle part of the clamping block 9 is provided with two clamping block anti-blocking bolts 8 for preventing the clamping block 9 from being blocked by the clamping sleeve 10,
