Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle testing technical field, concretely relates to a vehicle tie-down point strength test mechanism. BACKGROUND

[0002] Tie-down points are devices used to secure and support cargo units, widely used in cargo transportation, especially in container transportation and van trucks. To ensure that the goods will not move due to bumps or vibrations during transportation, so as to protect the goods from damage, and also to ensure the safety of the transportation tool.

[0003] According to relevant regulations, the number, installation position and strength of the tie-down points of the towing truck and the trailer must meet the corresponding requirements, so the strength of each tie-down point of the cargo box needs to be tested to ensure that the minimum allowable tension of the tie-down point meets the requirements and does not cause permanent deformation. At present, the test mechanism for tie-down point strength test can only test the strength of a single tie-down point, resulting in low work efficiency. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies in the prior art, the utility model provides a vehicle tie-down point strength test mechanism which can test the strength of two tie-down points at the same time.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical scheme: a vehicle tie-down point strength test mechanism, comprising a driving assembly, a tension member and a dynamometer;

[0006] The driving assembly comprises a telescopic member and a driving source, and the driving source can drive the telescopic member to elongate or shorten; both ends of the telescopic member are provided with a tension member, and one of the tension members is connected with the telescopic member through the dynamometer.

[0007] The two ends of the tension member are connected with two tie-down points respectively, and after the telescopic member is driven to shorten by the driving source, the two tie-down points can be tensioned, the dynamometer can measure the two tensions at the same time, and since the two tie-down points are subjected to the same force, the strength of the two tie-down points can be tested at the same time.

[0008] The above-mentioned vehicle tie-down point strength test mechanism has the beneficial effects that the strength test of double tie-down points can be carried out quickly and conveniently at the same time, and the work efficiency is improved.

[0009] Further, the telescopic member comprises a threaded sleeve and a screw rod, both ends of the threaded sleeve are threadedly connected with the screw rod, and rotation of the threaded sleeve can drive the two screw rods to move relatively.

[0010] By rotating the threaded sleeve to drive the two screw rods to move relatively, the overall elongation or shortening can be realized.

[0011] Further, the threaded sleeve is a bidirectional threaded sleeve, the threads of the two ends are opposite, and the two threaded rods are threaded at the two ends of the threaded sleeve respectively.

[0012] Since the threads of the two ends are opposite, when the threaded sleeve rotates, the two threaded rods can be driven to move in opposite directions, so that the whole is elongated or shortened.

[0013] Further, a pin hole is formed in the middle of the threaded sleeve in the radial direction, and the driving source is an external force arm, which is inserted into the pin hole.

[0014] The pin hole in the middle is used for inserting the external force arm, which can drive the threaded sleeve to rotate more conveniently.

[0015] Further, the tension member is a tension ring.

[0016] The tension ring is used to be connected with the fixing points, so as to exert tension on the two fixing points.

[0017] Further, threaded holes are formed in the ends of the threaded rods away from each other, and the tension ring and the force meter are connected with the threaded holes of the threaded rods through locking bolts.

[0018] The tension ring and the force meter are connected with the threaded rods through locking bolts, which has a good fixing effect. BRIEF DESCRIPTION OF DRAWINGS

[0024] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, but cannot limit the protection scope of the present application.​

[0025] Referring to Figure 1 and Figure 2 The utility model provides a kind of vehicle fastening point strength test mechanism, including drive assembly 10, tension member 20 and dynamometer 30, connect tension member 20 with fastening point, pull fastening point by drive assembly 10 to exert tension, so as to obtain the force value by dynamometer 30.

[0026] Specifically, drive assembly 10 includes telescopic member 11 and drive source, and the drive source can drive telescopic member 11 to lengthen or shorten.Two ends of telescopic member 11 are provided with tension member 20, and one of tension member 20 is connected with telescopic member 11 by dynamometer 30.Two ends of tension member 20 are connected with two fastening points respectively, and then drive telescopic member 11 to shorten by drive source, so as to tension two fastening points, and dynamometer 30 can measure two tensions simultaneously, and continue to shorten telescopic member 11, so as to continuously increase tension.Because the force on two fastening points is the same, the strength of two fastening points can be tested simultaneously.

[0027] In the embodiment, telescopic member 11 includes threaded sleeve 111 and screw rod 112, threaded sleeve 111 is bidirectional threaded sleeve 111, the thread direction of two ends is opposite, and screw rod 112 is threadedly connected to both ends.Because the thread direction of two ends is opposite, threaded sleeve 111 can drive two screw rods 112 to rotate in opposite directions when rotating, so as to drive two screw rods 112 to move relative to each other, and move closer to or away from each other, to lengthen or shorten as a whole.

[0028] The middle part of threaded sleeve 111 is provided with a pin hole in the radial direction, and the drive source is an external force arm 12, which is inserted into the pin hole.The pin hole in the middle part is used for inserting the external force arm 12, which can drive threaded sleeve 111 to rotate through the external force arm 12, and it is more convenient to exert force.

[0029] In the embodiment, tension member 20 is a tension ring, which is connected to the fastening point through a ring structure to exert tension on two fastening points.

[0030] Specifically, one end of screw rod 112, which is away from each other, is provided with a threaded hole, and both ends are connected with tension member 20 and dynamometer 30 respectively through locking bolt 113, which has good fixing effect, as shown in Figure 2 Screw rod and tension member are connected through bolt.

[0031] The working principle of the vehicle tie-down point strength testing mechanism is as follows: first, adjust the threaded sleeve 111 and the threaded rod 112 to a proper length, and fix the two ends of the tensioning member 20 to the tie-down points. Insert the force arm 12 into the middle of the threaded sleeve 111, rotate the threaded sleeve 111 and drive the two ends of the threaded rod 112 to move towards each other. Since the tie-down points are fixed on the carriage plate and cannot rotate, the threaded rod 112 cannot rotate with the threaded sleeve 111 and can only move axially, thereby exerting a pulling force on the two tie-down points from opposite directions, so as to test the strength of the two tie-down points.

[0032] The vehicle tie-down point strength testing mechanism can test the strength of two tie-down points, is convenient to use, improves work efficiency, and has strong practicability.

[0033] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
