Description

Technical Field

[0001] The utility model relates to the technical field of sand tank caps, in particular to a high-pressure sand tank cap. Background Art

[0002] In the technical field involved in the utility model, at present, there are some problems in the disassembly and assembly of the threaded sand pot cap: when disassembling by means of a steering wheel, the position of the steering wheel handle is fixed, and the hands need to be constantly changed for continuous rotation, which affects the disassembly and assembly efficiency; when the internal pressure of the sand pot is too high or the residual abrasives on the threads are not cleaned up, the problem of excessive resistance will be encountered during disassembly and assembly; and when the sand pot cap cannot be disassembled, adding a sleeve to the outside of the handle is a solution, but because the steering wheel handle is fixed in position and has a short length and a small outer diameter, it cannot be adapted to the sleeve, and it is easy to interfere with the on-site environment and cause the sleeve to fall off during use, posing a safety hazard.

[0003] The prior art has the technical problems that the handle direction is fixed, two-handed operation is required, and it is not easy to add a sleeve to the steering wheel handle. Summary of the invention

[0004] In view of the deficiencies of the prior art, the utility model provides a high-pressure sand tank cap, which solves the technical problems of the prior art that the handle direction is fixed, two-handed operation is required, and the steering wheel handle is not easy to be equipped with a sleeve.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a high-pressure sand tank cap, including a tank cap and a rocker ring, the upper end surface of the tank cap is provided with a positioning pin, the rocker ring is provided with a positioning hole, the positioning holes are respectively corresponding to the positions and sizes of the positioning pins, and the rocker ring is provided with a detachable rocker structure.

[0006] Preferably, the detachable rocker arm structure comprises a sleeve, and the sleeve is sleeved on the rocker arm ring.

[0007] Preferably, the detachable rocker arm structure also includes a crank sleeve and a bolt, the crank sleeve is rotatably mounted on the rocker arm ring, and the bolt is threadedly connected to the crank sleeve.

[0008] Preferably, the upper end of the tank cap is an inverted frustum, and there are four positioning pins, which are evenly distributed in a circle on the upper end of the tank cap.

[0009] Preferably, the rocker ring is a ring body with a straight rod, and there are four positioning holes, which are evenly distributed in a circle on the rocker ring.

[0010] Beneficial Effects

[0011] The utility model provides a high-pressure sand pot cap. The sand pot cap and the rocker ring are connected by a positioning pin, so that the rocker ring can be quickly disassembled, thereby improving operating efficiency; by rotating the rocker ring and selecting the installation angle, the direction of the rocker arm can be flexibly changed to avoid interference with the on-site environment, thereby ensuring that the sand pot cap can be smoothly disassembled and assembled; the rotatable crank installed on the rocker ring can rotate continuously without changing hands, thereby increasing disassembly and assembly efficiency and saving time and labor; the crank can be disassembled and the sleeve can be replaced to extend the force arm, thereby preventing the problem of excessive disassembly and assembly resistance due to excessive pressure or abrasive contamination of the thread, thereby ensuring that the sand pot cap can be smoothly disassembled and assembled.

[0014] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, rather than all the embodiments. The detailed description is as follows.

[0015] See also Figure 1 The utility model provides a technical solution: a high-pressure sand pot cap, comprising a tank cap 1 and a rocker ring 2, wherein a positioning pin 3 is provided on the upper end surface of the tank cap 1, and a positioning hole is provided on the rocker ring 2, wherein the positioning holes are respectively in the same position and size as the positioning pin 3, and a detachable rocker structure is provided on the rocker ring 2. In order to realize the rapid disassembly and assembly of the sand pot cap, a metal rocker ring 2 that can change the direction of the force arm and a detachable metal crank and sleeve 4 can be used. First, the metal rocker ring 2 is fixed to the four pins on the sand pot cap to ensure a stable connection. The threaded hole position on the metal rocker ring 2 is designed to install a detachable metal crank, and the sand pot cap is rotated to the end of the high-pressure tank port by using the metal crank. When the force arm needs to be extended, the metal crank can be removed, and then the sleeve 4 is installed to securely connect by locking the thread. In this way, by alternately using the metal crank and the sleeve 4, the length of the force arm can be flexibly changed to realize the operational requirements of rapid disassembly and assembly of the sand pot cap. This design combines the direction-adjustable metal rocker arm ring 2 with the detachable metal crank handle and sleeve 4, thereby improving the convenience and efficiency of operation and ensuring the smooth disassembly and assembly process.

[0016] This embodiment is further configured such that the detachable rocker arm structure includes a sleeve 4 , and the sleeve 4 is sleeved on the rocker arm ring 2 .

[0017] The present embodiment is further configured such that the detachable rocker arm structure also includes a crank cover 5 and a bolt 6 , wherein the crank cover 5 is rotatably mounted on the rocker arm ring 2 , and the bolt 6 is threadedly connected to the crank cover 5 .

[0018] The present embodiment is further configured such that the upper end of the tank cap 1 is an inverted frustum, the number of the positioning pins 3 is four, and the positioning pins 3 are evenly distributed in a circle on the upper end of the tank cap 1 .

[0019] This embodiment is further configured such that the rocker ring 2 is a ring body with a straight rod, and there are four positioning holes, which are evenly distributed in a circle on the rocker ring 2 .

[0020] The detailed connection means are well known in the art; Figure 1 As shown, align the rocker ring 2 with the tank cap 1, ensure that the positioning pin 3 corresponds to the positioning hole, and then gently rotate the rocker ring 2 by hand until it is fixed in position; if the sleeve 4 is required, put the sleeve 4 on the rocker ring 2, and ensure that the sleeve 4 is firmly installed to extend the lever arm.

[0021] The appropriate installation angle is selected by rotating the rocker arm ring 2 so that the direction of the rocker arm can adapt to the actual operating environment and avoid interference and obstruction.

[0022] Hold the rotatable crank with your hand for continuous rotation without changing hands, which improves the efficiency of disassembly and assembly.

[0023] If the resistance is too great to be disassembled, the crank handle can be removed, the sleeve 4 can be replaced, the force arm can be extended, the resistance can be reduced, and then the disassembly operation can be carried out.

[0024] During operation, pay attention to the stability and alignment of the installation position to ensure that the positioning pin 3 is completely consistent with the positioning hole.

[0025] Be careful during disassembly and assembly to avoid accidental injury or damage.

[0026] If there are special circumstances that prevent smooth operation, you should stop in time and seek help or perform necessary maintenance.
