Description

Technical Field

[0001] The utility model belongs to the field of spanners for disassembling and assembling motor fixing bolts, in particular to a spanner for motors. Background Art

[0002] like Figure 5 As shown, in the prior art, the plunger pump motor is set on the slide rail 4 through the bolt 5 to be tightened, and the bolt seat is a 42 mm*42 mm square bolt seat. When replacing or adjusting the power belt of the plunger pump motor, it is necessary to loosen and tighten the bolt 5 to be tightened. At this time, someone must assist. The assistant uses a 375 mm adjustable wrench to make a spare clamp, and the operator uses the wrench to loosen and tighten the fixing screw on the upper part of the bolt 5 to adjust the position of the motor. However, due to the small space at the plunger pump motor, it is not suitable for multiple people to cooperate in operation, and the 375 mm adjustable wrench used for the spare clamp is easy to slip from the square bolt seat, which is time-consuming and laborious to operate, seriously affecting work efficiency. Utility Model Content

[0003] The utility model aims to provide a spanner for a motor, so as to solve the technical problems of time-consuming and labor-intensive adjustment of the motor position and low working efficiency in the prior art.

[0004] To achieve the above purpose, the technical solution of the motor wrench provided by the utility model is:

[0005] A motor wrench comprises a sleeve for clamping on a bolt seat and a fixing structure for preventing the sleeve from falling off the bolt seat, a cantilever is provided on the side wall of the sleeve, and a first stopper structure for cooperating with a slide rail stopper under the motor to prevent the sleeve from rotating is provided at one end of the cantilever away from the sleeve;

[0006] The cantilever is arranged on the side wall of one side of the sleeve and forms a counterweight type fixed structure, or the cantilever is provided with a magnet that cooperates with the slide rail magnetically to form a fixed structure;

[0007] The first stopping structure is a baffle or a stop rod.

[0008] The beneficial effects are as follows: the utility model is an improved invention. The motor wrench is clamped on the bolt seat by the sleeve, and the sleeve is prevented from rotating by the first anti-rotation structure, so that the motor wrench can be used as a backup pliers. When the operator uses the wrench to loosen or tighten the fixing screws on the upper part of the bolt to be tightened, the motor wrench used as a backup pliers will not fall off the bolt seat due to the fixed structure. At the same time, when the fixing screws are turned, the baffle contacts the slide rail to prevent the bolt seat from rotating. In summary, the motor wrench disclosed in the utility model can be used by a single person to complete the work of replacing or adjusting the motor power belt, achieving the technical effect of saving time and effort and improving work efficiency.

[0009] By arranging the cantilever on the side wall of one side of the sleeve and clamping the sleeve on the bolt seat, when the motor wrench is used as a backup clamp, the end of the cantilever far away from the sleeve has a large acceleration when falling, while the sleeve is affected by friction and has a small acceleration when falling, thereby causing the motor wrench to rotate. When the motor wrench rotates a small angle, the bolt seat blocks the sleeve from continuing to rotate, thereby fixing the motor wrench on the bolt seat, and conveniently and quickly preventing the sleeve from falling off the bolt seat.

[0010] The magnetic attraction between the magnet and the slide rail can also conveniently and quickly prevent the sleeve from falling off the bolt seat.

[0011] The first stop structure is arranged as a baffle or a baffle rod, which has a simple structure and good effect.

[0012] Furthermore, two ends of the first stop structure protrude from the upper surface and the lower surface of the cantilever respectively, and the magnets are respectively arranged on the upper surface and the lower surface of the cantilever.

[0013] The beneficial effect is: by making the two ends of the first stop structure protrude from the upper surface and the lower surface of the cantilever respectively, and making the magnets respectively arranged on the upper surface and the lower surface of the cantilever, it is possible to use the motor wrench without distinguishing between the front and the back.

[0014] Furthermore, it also includes a latch, a groove is provided on the magnet, and the magnet is connected to the cantilever through the groove and the latch.

[0015] The beneficial effect is that by setting the groove, the upper surface of the magnet can be flush with the upper surface of the pin, so that the magnet can be closer to the slide rail, thereby enhancing the magnetic attraction between the motor wrench and the slide rail, and further preventing the sleeve from falling off the bolt seat.

[0016] Furthermore, the first stop structure is provided with a second stop structure for being inserted into the slide rail and cooperating with the slide rail stop to prevent the sleeve from falling off the bolt seat.

[0017] The beneficial effect is that the second stop structure can further prevent the sleeve from falling off the bolt seat, and can also prevent the motor wrench from falling off the slide rail.

[0018] Furthermore, the second stop structure is an adjustable stop structure, and the adjustable stop structure has a locked state in which the stop structure is inserted into the slide rail and a released state in which the stop structure is not inserted into the slide rail.

[0019] The beneficial effect is: by setting the second stop structure as an adjustable stop structure, the adjustable stop structure can be inserted into the slide rail when the sleeve needs to be fixed on the bolt seat; when the motor is disassembled with a wrench, the adjustable stop structure is pulled out from the slide rail.

[0020] Furthermore, the adjustable stop structure is an adjusting bolt.

[0021] The beneficial effect is that the adjustable stop structure is set as an adjusting bolt, which has a simple and reliable structure.

[0022] Furthermore, the latch is a bolt.

[0023] The beneficial effect is that by setting the latch as a bolt, the structure is simple and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described in detail below in conjunction with the embodiments.

[0032] Specific embodiment 1 of the motor wrench provided by the utility model:

[0033] like Figure 1-5 As shown, taking the use of the motor wrench provided by the utility model to adjust the plunger pump motor set on the slide rail 4 through the bolt 5 to be tightened as an example, the specific embodiment 1 of the utility model is introduced in detail.

[0034] The utility model discloses a motor wrench, comprising a sleeve 11, a cantilever 12 connected to the side wall of the sleeve 11, and a fixing structure for preventing the sleeve 11 from falling off the bolt seat of the bolt 5 to be tightened. A baffle 13 is provided at one end of the cantilever 12 away from the sleeve 11, and the baffle 13 contacts the slide rail 4 below the motor to be adjusted to prevent the sleeve 11 from rotating. The two ends of the baffle 13 protrude from the upper surface and the lower surface of the cantilever 12 respectively, so that it is not necessary to distinguish the front and back sides when using the motor wrench. The sleeve 11, the cantilever 12 and the baffle 13 constitute a wrench body 1. The baffle 13 is also provided with an adjustable stop structure for inserting into the slide rail 4. In this embodiment, the adjustable stop structure has two states: a locked state when inserted into the slide rail 4 and a released state when not inserted into the slide rail 4. When the adjustable stop structure is inserted into the slide rail 4, it can cooperate with the slide rail stop to further prevent the motor wrench from falling off the slide rail 4, and also prevent the sleeve 11 from falling off the bolt seat; when the adjustable stop structure is not inserted into the slide rail 4, it is convenient for installing and removing the motor wrench. However, in other embodiments, the second stop structure can also be a stop structure in a non-adjustable state, for example, a protrusion provided on the baffle 13.

[0035] In this embodiment, the cantilever 12 is disposed on a side wall of one side of the sleeve 11 , and the sleeve 11 is used to be clamped on the bolt seat and cooperate with the cantilever 12 to form a fixed structure.

[0036] When in use, first clamp the sleeve 11 on the bolt seat of the bolt 5 to be tightened of the motor to be adjusted, and clamp the sleeve 11 on the bolt seat, so that when the motor wrench is used as a backup clamp, the acceleration of the cantilever 12 end away from the sleeve 11 is large, and the sleeve 11 is affected by the friction force, and the acceleration of the fall is small, which causes the motor wrench to rotate. When the motor wrench rotates a small angle, the bolt seat blocks the sleeve 11 from continuing to rotate, and then the motor wrench is fixed on the bolt seat, which prevents the sleeve from falling off the bolt seat. After that, the baffle 13 is contacted with the slide rail 4 to prevent the motor wrench from rotating with the bolt seat, and the adjusting bolt 3 is screwed into the slide rail 4, thereby further preventing the sleeve from falling off the bolt seat. Finally, use other wrenches to loosen and tighten the fixing screws on the upper part of the bolt 5 to be tightened. After use, the adjusting bolt 3 is screwed out of the slide rail 4 and the motor wrench is removed.

[0037] The utility model fixes the bolt seat of the bolt 5 to be tightened by the sleeve 11, and prevents the motor wrench used as a spare pliers from falling off the slide rail 4 and the bolt seat by the fixing structure and the adjustable stop structure. When tightening the fixing screw, the motor wrench is prevented from rotating by the baffle 13, thereby preventing the bolt seat from rotating. In summary, the motor wrench disclosed by the utility model can be used by a single person to complete the work of replacing or adjusting the motor power belt, achieving the technical effect of saving time and labor and improving work efficiency.

[0038] Specific embodiment 2 of the motor wrench provided by the utility model:

[0039] The main difference between this embodiment and the specific embodiment 1 is that: in this embodiment, it also includes a magnet 2 and a latch 21 that cooperate with the slide rail magnetic attraction. The magnet 2 constitutes a fixed structure, and the latch 21 is a bolt. The cantilever 12 is also provided with a mounting hole 14, and the magnet 2 is provided with a groove. The latch 21 is located in the groove and cooperates with the mounting hole 14 to pin the magnet 2 to the cantilever 12. The magnet 2 is respectively arranged on the upper surface and the lower surface of the cantilever 12, so that there is no need to distinguish between the front and back sides when using the motor wrench. Compared with the specific embodiment 1, when using this embodiment, the motor wrench is adsorbed on the slide rail 4 by the magnet 2, thereby preventing the sleeve from falling off from the bolt seat, which is convenient and fast, and has high reliability.

[0040] Specific embodiment 3 of the motor wrench provided by the utility model:

[0041] The main difference between this embodiment and the specific embodiment 2 is that in this embodiment, the cantilever 12 is symmetrically arranged at both ends of the sleeve 11, and a baffle 13 is arranged at one end of the cantilever 12 away from the sleeve 11. The baffle 13 is located on both sides of the slide rail 4. At this time, the magnets that are magnetically matched with the slide rail constitute a fixed structure. Figure 5 As shown, the bolts 5 to be tightened fix the slide rail 4 and the square tube together, and the baffle 13 in the specific embodiment 1 is far away from the bolt seat of the bolts 5 to be tightened. The advantage of this is that the baffle 13 can avoid the square tube, so there is no need to limit the specifications of the baffle 13. Compared with the specific embodiment 2, the baffle 13 is arranged just below the square tube in this embodiment. The symmetrically arranged baffle 13 and the adjusting bolt 3 can better prevent the sleeve 11 from falling off from the bolt seat while better preventing the motor from being rotated by the wrench, thereby better preventing the sleeve 11 from rotating.

[0042] Specific embodiment 4 of the motor wrench provided by the utility model:

[0043] The main difference between this embodiment and the specific embodiment 1 is that in this embodiment, the second stop structure is not included. Compared with the specific embodiment 1, this embodiment does not include the second stop structure, which can reduce the weight of the motor wrench, simplify the operation, and complete the work of replacing or adjusting the motor power belt more quickly.

[0044] Specific embodiment 5 of the motor wrench provided by the utility model:

[0045] The main difference between this embodiment and the specific embodiment 1 is that in this embodiment, the first stop structure is a stopper rod. Compared with the specific embodiment 1, the stopper rod can reduce the weight of the motor wrench, thereby further preventing the sleeve hole from falling off the bolt seat.

[0046] Specific embodiment 6 of the motor wrench provided by the utility model:

[0047] The main difference between this embodiment and the specific embodiment 1 is that in this embodiment, one end of the baffle 13 protrudes from the upper surface of the cantilever 12, and the magnet 2 is arranged on the upper surface of the cantilever 12. Compared with the specific embodiment 1, when using the motor wrench, although it is not possible to use it without distinguishing the front and back, the weight of the motor wrench can be reduced, thereby further preventing the sleeve hole from falling off the bolt seat.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
