Description

Technical Field

[0001] The utility model belongs to the research field of screw processing technology, and in particular relates to a tool box for applying an anti-seizure agent for screws. Background Art

[0002] In some special environments or special occasions where bolts and screws are used, a certain amount of anti-seize agent must be applied to the threads of the screws or bolts before use to facilitate the installation and removal of the screws. Anti-seize agent is a bolt connection assembly lubricant that can reduce the friction between the bolt and the nut, making it easier for the bolt to rotate under a given tightening torque, thereby achieving the desired tightening effect. Therefore, anti-seize agent is widely used.

[0003] The patent with publication number CN201613215U discloses a rotating device for spraying anti-seizure agent on bolts, including at least one working unit, each of which includes multiple driving wheels, each of which rotates in the same direction and at the same speed; a bolt is supported between two adjacent driving wheels, and the threaded portion of the bolt extends from the end of each driving wheel; under the action of friction, the bolt rotates with the driving wheel. When in use, the operator controls the rotation of the bolt by turning the hand wheel with his left hand and holds the spray bottle with his right hand, so that the spraying of the anti-seizure agent and the rotation of the bolt are carried out simultaneously. When the bolt completes the rotation, the anti-seizure agent is also fully sprayed on the thread surface.

[0004] However, in the above technical solution, the operator needs to spray the bolts manually, and during the spraying process, excess anti-seizure agent will be sprayed to the outside of the rotating device, contaminating the operating table and causing inconvenience in operation. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem of inconvenient operation of the existing spraying device.

[0006] In order to achieve the above-mentioned purpose, the technical idea adopted by the utility model is: by adding a nozzle ring on the outside of the screw limiting hole and adding a spraying mechanism connected to the nozzle ring, the surface of the screw is sprayed around; when in use, the anti-bite agent is delivered to the nozzle ring through the spraying mechanism to spray the screw, and there is no need for the operator to spray manually. The operation is convenient and it can ensure that the screw is sprayed all around.

[0007] Based on the above technical ideas, the technical solution adopted by the utility model is:

[0008] A tool box for applying a screw anti-seizure agent, comprising a box body, wherein the box body further comprises:

[0009] retractable anti-seize agent tube;

[0010] The screw limiting cylinder comprises a screw limiting hole, a nozzle ring and a flow ring; one end of the flow ring is connected to the telescopic anti-seizure agent tube through a connecting pipe, and the other end is connected to the screw limiting hole through the nozzle ring;

[0011] The spraying mechanism is arranged at the end of the telescopic anti-bite agent tube, and the anti-bite agent is delivered to the nozzle ring by squeezing the telescopic anti-bite agent tube to spray the screws arranged in the screw limiting holes.

[0012] To further define the above technical solution, preferably, the nozzle ring includes a plurality of nozzles;

[0013] The multiple nozzles are arranged around the screw limiting hole at equal intervals.

[0014] As a further limitation of the above technical solution, a scraping portion is provided above the screw limiting hole.

[0015] As a further limitation of the above technical solution, an anti-seizure agent recovery cylinder is provided below the screw limiting hole.

[0016] In a further limitation of the above technical solution, the spraying mechanism includes an electric push rod and a push plate;

[0017] The push plate is connected to the electric push rod, and the push plate is located close to one end of the telescopic anti-bite agent tube.

[0018] Beneficial effects of the utility model:

[0019] The utility model sprays the screw surface around by adding a nozzle ring and a spraying mechanism connected to the nozzle ring on the outer side of the screw limiting hole; when in use, the spraying mechanism is controlled to work by clicking a switch on the control panel, and the spraying mechanism squeezes the retractable anti-bite agent tube so that the anti-bite agent is transported to the nozzle ring under the action of the squeezing force to spray the screw, without the need for manual spraying by an operator, and the operation is convenient.

[0020] The nozzle ring includes a plurality of nozzles, and the plurality of nozzles are arranged at equal intervals around the screw limiting hole, thereby ensuring uniform spraying of the anti-seizure agent to the greatest extent.

[0021] Secondly, a scraping portion is provided above the screw limiting hole so that after the application of the screw is completed and before the screw is taken out, the excess anti-bite agent on the surface of the screw can be scraped off, so as to achieve a better application effect.

[0022] In addition, a recovery cylinder is provided below the screw limiting hole for recovering excess anti-seizure agent.

[0023] Moreover, the screw limiting cylinder, retractable anti-bite agent tube and spraying mechanism provided by the utility model are all arranged in a box body, which is convenient for operators to carry and operate. When applying, only the screw or bolt needs to be placed in the screw limiting hole and the switch on the control panel can be used to automatically complete the spraying of the anti-bite agent. The operation is simple and maintenance is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0037] like Figure 1-7 As shown, a screw anti-seize agent coating box provided by the utility model includes a box body 4, and a retractable anti-seize agent tube 1, a screw limiter 2 and a spraying mechanism 3 arranged inside the box body 4. In order to facilitate carrying screws and bolts, a screw storage box 8 is also arranged inside the box body 4. Among them, the above devices are all slotted inside the box body 4 to prevent shaking.

[0038] like Figure 2 As shown, the telescopic anti-bite agent tube 1 is a telescopic structure with an opening. Specifically, the opening of the telescopic anti-bite agent tube 1 is connected to the connecting tube 7, and the other end of the connecting tube 7 is connected to the screw limit tube 2.

[0039] The retractable bite-release agent tube 1 is fixed in the box body 4 by a C-shaped clamp 12 .

[0040] The spraying mechanism 3 includes a power source 31 , a driving unit 32 and a control unit 33 .

[0041] The driving part 32 comprises an electric push rod 32a and a push plate 32b. The push plate 32b is arranged at the end of the telescopic anti-bite agent tube 1, and one end of the push plate 32b away from the telescopic anti-bite agent tube 1 is connected to the electric push rod 32a.

[0042] One end of the electric push rod 32a away from the telescopic anti-seize agent tube 1 is connected to the motor.

[0043] The control unit 33 is connected to the power supply 31 and the motor respectively; the control unit 33 controls the start and stop of the spraying mechanism 3 and the time of its spraying operation by controlling the rotation time and rotation direction of the electric push rod 32a in the driving unit 32.

[0044] When in use, the electric push rod 32a rotates under the action of the motor, causing the electric push rod 32a to extend, and then the push plate 32b set at one section of the electric push rod 32a moves toward one end of the retractable anti-bite agent tube 1 to squeeze the retractable anti-bite agent tube 1, causing the retractable anti-bite agent tube 1 to shrink and its internal space to shrink, and then the anti-bite agent in the retractable anti-bite agent tube 1 enters the screw limiting cylinder 2 through the connecting tube 7.

[0045] The screw limiting cylinder 2 is a cylindrical structure, comprising a screw limiting hole 21 , a nozzle ring 22 and a flow ring 23 .

[0046] The screw limiting hole 21 is a T-shaped hole, and is arranged at the center of the screw limiting tube 2, so that it is convenient for the operator to place the screw or bolt in the screw limiting hole 21 for spraying operation, and the operator to take out the screw or bolt after spraying.

[0047] The nozzle ring 22 includes a plurality of nozzles arranged at equal distances, and the plurality of nozzles are arranged outside the screw limiting holes 21 .

[0048] The flow ring 23 is a circular through hole, and is connected to the nozzle ring 22, so that one end of the flow ring 23 is connected to the telescopic anti-seizure agent tube 1 through the connecting pipe 7. The flow ring 23 is provided with a connecting hole 13 connected to the connecting pipe 7.

[0049] A housing 26 and a fixing bolt 25 are provided outside the screw limiting hole 21 .

[0050] The fixing bolt 25 is used to fix the housing 26 to the screw limiting cylinder 2 .

[0051] The housing 26 is provided with a through hole with the same inner diameter as the connecting hole 13, so that the connecting pipe 7 passes through the through hole to connect with the connecting hole 13 on the flow ring 23. Specifically, the connecting pipe 7 is connected to the connecting hole 13 by threads.

[0052] In actual use, the anti-seize agent enters the flow ring 23 through the connecting pipe 7 and flows in the flow ring 23 until it is evenly distributed on the flow ring 23 , and then the anti-seize agent 7 is sprayed on the surface of the screw or bolt through the nozzle ring 21 .

[0053] In order to facilitate the recovery of the excess anti-seize agent sprayed, a recovery hole connected to the screw limit hole 21 is further provided at the bottom of the screw limit tube 2, and a thread is provided inside the recovery hole so as to be connected to the recovery tube 6 provided below the screw limit tube 2. In this way, during the spraying operation, the excess anti-seize agent can be recovered into the recovery tube 6 for reuse, thereby reducing resource waste. Specifically, an interface is provided above the recovery tube 6; the outer surface of the interface is provided with a thread matching and connecting with the recovery hole.

[0054] Since it is easy for too much anti-bite agent to be left on the screws or bolts during the spraying process, a scraper portion 5 is further provided above the screw limiting hole. In this way, after the spraying operation is completed, when the operator takes out the screws or bolts, the surface of the screws or bolts passes through the scraper portion 5, and the excess anti-bite agent can be scraped off.

[0055] Specifically, the scraper part 5 is a fan-shaped structure, and a scraper brush is provided at its front end. In practical applications, a plurality of scrapers 5 are arranged at equal intervals at the opening of the screw limiting hole 21. The scraper part 5 is made of soft silicone.

[0056] Moreover, a fixing strip 9 and a fixing card 10 are provided in the screw storage box 8. The fixing card 10 is a square structure having a plurality of grooves arranged at equal distances so that the screws and bolts can be fixedly placed in the grooves to prevent the screws and bolts from shaking in the box body 4.

[0057] Specifically, a fixing strip 9 is provided between two adjacent grooves, and the fixing strip 9 is detachably connected, so that the width of the groove can be flexibly adjusted to be suitable for screws or bolts of different sizes. In practical applications, the operator can store the screws and bolts in order so that the screws and bolts can be installed in situ later after being coated.

[0058] Furthermore, a cleaning box 11 is included, which can clean the surface of the screws or bolts before spraying.

[0059] Application examples:

[0060] Before the spraying operation starts, open the box 4, connect the retractable anti-bite agent tube 1 filled with anti-bite agent in the C-shaped clamp 12, and connect the opening of the retractable anti-bite agent tube 1 to the connecting tube 7, and connect the other end of the connecting tube 7 to the connecting port 13 on the current ring 23, and connect the control unit 33 to the power supply 31 and the drive unit 32 to complete the preparation work before spraying.

[0061] Then, the operator takes out the screw or bolt, and places it in the screw limiting hole 21, and sets the working time of the electric push rod 32b through the control unit 33, so that the electric push rod 32b drives the push plate 32b to move toward one end of the retractable anti-bite agent tube 1, squeezing the retractable anti-bite agent tube 1 to contract, thereby allowing the anti-bite agent to flow from the connecting tube 7 into the flow ring 23, and then be sprayed out from the nozzle ring 21 through the flow ring 23, completing the spraying of the screw or bolt.

[0062] After the spraying operation is completed, the operator takes out the screw or bolt and scrapes off the excess anti-bite agent on the surface of the screw or bolt through the scraper 5. The excess anti-bite agent flows into the recovery tube 6 arranged below the screw limit hole 21 under the action of gravity and can be reused.

[0063] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
