In order to solve the poor problem of gland fastening tool performance among the prior art, this application provides a two eave tile spanners of gland.
As shown in fig. 1, the gland double-hook wrench of the present application includes a main body 10, a handle 20, and a plurality of fastening hooks 30. The main body part 10 is arc-shaped, the main body part 10 comprises a main body section 11, a first clamping section 12 and a second clamping section 13, and the first clamping section 12 and the second clamping section 13 are respectively connected with two ends of the main body section 11; one end of the handle 20 is connected with the main body part 10, and the other end of the handle 20 extends along one side of the direction far away from the center of the main body part 10; the first clamping section 12 and the second clamping section 13 are respectively provided with at least one fastening hook 30, the fastening hook 30 is arranged on one side of the main body 10 away from the handle 20, and the fastening hook 30 extends along the direction close to the center of the main body 10.
When the gland double-hook spanner with the structure is used, an operator can control the main body part 10 to be close to a gland to be fastened through the handle 20, and align the fastening hooks 30 with the slots of the gland respectively. When the fastening hooks 30 are inserted into the slots of the gland, the main body section 11, the first clamping section 12 and the second clamping section 13 of the main body 10 are attached to the gland. At this time, the handle 20 can drive the main body 10 and the fastening hooks 30 to rotate, so as to fasten the gland. Moreover, the double-hook-end wrench for the gland can effectively prevent the gland from slipping in the process of rotating the gland and can improve the working efficiency of operators.
It should be noted that the double-hook-end wrench for the gland in the present application can be used for fastening the gland, and can also be used for detaching the gland.
Specifically, the arc of the body 10 is 90 degrees or more and 180 degrees or less. By such an arrangement, not only can the main body 10 and the gland have a sufficient contact area, but also the plurality of fastening hooks 30 can be inserted into the insertion grooves of the gland more easily.
In one embodiment of the present application, the joints between the first clamping section 12 and the second clamping section 13 and the main body section 11 on the side close to the center of the main body 10 are smooth transitions, and the radian of the main body 10 is 180 degrees.
Specifically, the fastening hooks 30 are two, and the two fastening hooks 30 are symmetrically disposed with respect to the handle 20. Through the arrangement, after the two fastening hook heads 30 are inserted into the slots of the gland, when the handle 20 is used for rotating the fastening hook heads 30, the two fastening hook heads 30 are symmetrically arranged relative to the handle 20, so that the stability of stress of the gland can be effectively ensured. And, can also play certain guard action to the gland through setting up like this to guarantee at the in-process of fastening gland, the gland can not receive the damage.
Optionally, the angle between the two fastening hooks 30 is 180 degrees. In one embodiment of the present application, the pressing cover has 6 slots, and the 6 slots are uniformly distributed on the circumference of the pressing cover, so that the included angle between two adjacent slots is 60 degrees. Therefore, the included angle between the two fastening hook heads 30 is set to be 180 degrees, so that the two fastening hook heads 30 can be ensured to be respectively inserted into the two opposite slots, and the stress of the gland is ensured to be more stable.
In addition, since the plunger pump is generally provided with a plurality of pressing covers, and the interval between the pressing covers is small, when the pressing covers are fastened, the fastening hook 30 needs to be pulled out from the insertion groove after the fastening hook 30 is rotated by a certain angle, and then inserted into the insertion groove again after the position is adjusted.
Specifically, two fastening hooks 30 are respectively disposed at an end of the first clamping section 12 away from the main body section 11 and an end of the second clamping section 13 away from the main body section 11. Through setting up like this, can guarantee effectively that operating personnel is more laborsaving at the in-process of fastening gland.
Optionally, an included angle between a line connecting two sides of the fastening hook 30 to the center of the main body 10 is greater than 20 degrees and less than 40 degrees. The purpose of this arrangement is mainly to ensure that the fastening hook 30 can be fitted into the slot of the gland, and to increase the contact area between the fastening hook 30 and the slot as much as possible.
Specifically, the surface of the fastening hook 30 has a carburized layer. Through such an arrangement, not only the strength of the surface of the fastening hook 30 can be ensured, but also the fastening hook 30 can be more easily pulled out from the slot. Thereby reducing the friction between the fastening hook head 30 and the gland slot, reducing the friction between the fastening hook head 30 and the gland, and prolonging the service life of the fastening hook head 30 and the gland.
Specifically, the cross-sectional area of the main body section 11 is larger than the cross-sectional area of the first clamping section 12 and the cross-sectional area of the second clamping section 13, respectively; the first clamping section 12 and the second clamping section 13 are symmetrically arranged with respect to the main body section 11; the main body section 11, the first clamping section 12 and the second clamping section 13 are of an integrally formed structure. The purpose of this is mainly to strengthen the stability of the main body 10 by the main body segment 11, thereby preventing the main body 10 from being deflected or shaken during fastening of the gland, and improving safety in use.
Specifically, the plurality of fastening hooks 30 are the same length. Through the arrangement, the uniform stress between the plurality of fastening hooks 30 and the gland can be further effectively ensured.
Optionally, the side of the handle 20 remote from the body portion 10 is provided with anti-slip threads.
Optionally, the side of the handle 20 remote from the main body 10 is provided with an anti-slip cover.
Through setting up like this, can play anti-skidding effect through anti-skidding screw thread and antiskid cover to guarantee operating personnel's the sense of gripping and reduce and skid.
From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:
1. the problem that the using part of a filler gland fastening tool is stable in the prior art is effectively solved;
2. the problem that the number of supporting points of a gland fastening tool is small is also solved;
